FIELD OF THE INVENTION

The present invention relates to composite reeling devices and more particularly to a composite reeling device for reeling cables, steel ropes, cords, etc.

BACKGROUND OF THE INVENTION

A reeling device is for use in reeling cables, steel ropes, and cords (hereinafter collectively referred to as wires) to facilitate the storage and transport thereof Referring toFIG. 1, there is shown a schematic view of a conventional reeling device.

Referring toFIG. 1, the conventional reeling device comprises an internal shaft60, a drum70, two outer wheel frames80and a plurality of inner wheel frames90. The internal shaft60has two opposing ends each provided with an end plate61. The internal shaft60is penetratingly disposed in the drum70. The two outer wheel frames80are disposed at the two opposing ends of the drum70, respectively. The outer wheel frames80each have a plurality of connection bars81and an outer ring84. The connection bars81have welding portions82coupled to the end plates61and welding portions83coupled to the drum70. The connection bars81are fixedly disposed inward to the outer ring82and arranged radially. The inner wheel frames90each have a supporting ring92and a plurality of spokes93. The spokes93are fixedly disposed inward to the supporting ring92and arranged radially. The spokes93each have a welding portion91coupled to the drum70. The inner wheel frames90are arranged between the two outer wheel frames80to define a plurality of spaces for receiving the wires.

However, the conventional reeling device is characterized in that the outer wheel frames80and the inner wheel frames90are coupled to the drum70and the internal shaft60by welding, and thus it is impossible to remove the outer wheel frames80and the inner wheel frames90. Since there are spaces between each of the outer wheel frames80and two adjacent inner wheel frames90, it is difficult to stack up the conventional reeling devices, thereby causing a waste of storage space and an increase in transport costs (because just a limited number of the conventional reeling devices can be carried by a vehicle.)

SUMMARY OF THE INVENTION

It is an objective of the present invention to provide a composite reeling device which is not only easy to use and easy to assemble but also allows its components, such as a shaft, sleeve, outer wheel frames and inner wheel frames, to be separated, stored, and stacked during a storage process or a transport process, not to mention that more said composite reeling devices can be stored in a specific storage space than their conventional counterparts.

In order to achieve the above and other objectives, the present invention provides a composite reeling device which comprises a shaft, a sleeve, two outer wheel frames and a plurality of inner wheel frames. The shaft has two opposing ends each provided with a fixing end plate. The sleeve is fitted around the shaft and has two opposing ends each provided with a fixing flange. The fixing flanges correspond in position to the fixing end plates, respectively. The two outer wheel frames are disposed at the two ends of the sleeve, respectively, and removably coupled to the fixing flanges and the fixing end plates, respectively. The inner wheel frames each comprise a belt, a supporting ring and a plurality of spokes. The spokes each have two ends connected to corresponding ones of the belts and corresponding ones of the supporting rings, such that the belts are fitted around the sleeve removably.

The composite reeling device further comprises an adjustment unit disposed at two adjacent inner wheel frames removably.

Regarding the composite reeling device, the adjustment unit comprises a plurality of rods each having two ends coupled to the spokes of two adjacent inner wheel frames removably.

Regarding the composite reeling device, a screw hole is disposed at each of the two ends of each rod, and the spokes each have a plurality of screw holes arranged lengthwise and adapted to fasten the rods, respectively.

Regarding the composite reeling device, the outer wheel frames each comprise a fixing disk, an outer ring and a plurality of connection elements, with the connection elements connected to the fixing disks and the outer rings, and the fixing disks are removably coupled to the fixing flanges and the fixing end plates.

Regarding the composite reeling device, a protruding portion and a positioning portion are disposed at the two opposing ends of the shaft, respectively, and correspond in position to the two fixing end plates, respectively, wherein the fixing disks each have a central hole and a positioning opening, wherein the protruding portions are penetratingly disposed in the central holes, respectively, and the positioning portions are engaged with the positioning openings, respectively.

Regarding the composite reeling device, the fixing flanges each have a positioning slot, and the fixing disks each have a positioning bump, wherein the positioning bumps correspond in shape and position to the positioning slots, respectively, to therefore enable engagement therebetween.

Regarding the composite reeling device, the sleeve has a positioning guiding groove extending axially from an end of the sleeve to another end of the sleeve, wherein a positioning sliding bump protrudes from each of the belts of the inner wheel frames and slides along the positioning guiding groove.

Regarding the composite reeling device, the inner wheel frames are arranged equidistantly.

Therefore, the composite reeling device has an advantage, that is, a plurality of inner wheel frames define a plurality of spaces for receiving the wires of different types to thereby enhance ease of use. The composite reeling device has some other advantages: the shaft, sleeve, outer wheel frames and inner wheel frames can be removed during a storage process and a transport process so as to be stored and stacked separately. Unlike the prior art, the present invention has important advantages as follows: storing more composite reeling devices in a space of a specific volume, increasing the storage space utilization rate, and using less vehicles required for transport. Furthermore, in this embodiment, the composite reeling device is equipped with the adjustment unit for adjusting the perimeter of the windings of the wires.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

According to an embodiment of the present invention, a composite reeling device is for use in reeling cables, steel ropes and cords (hereinafter collectively referred to as wires) to facilitate the storage and transport thereof

Referring toFIG. 2, there is shown an exploded view of a composite reeling device1according to an embodiment of the present invention. The composite reeling device1comprises a shaft10, a sleeve20, two outer wheel frames30and a plurality of inner wheel frames40. A fixing end plate11is disposed at each of the two opposing ends of the shaft10. The sleeve20is fitted around the shaft10. A fixing flange21is disposed at each of the two opposing ends of the sleeve20. The fixing flanges21correspond in position to the fixing end plates11, respectively. The two outer wheel frames30are disposed at the two ends of the sleeve20, respectively. The outer wheel frames30are removably coupled to the fixing flanges21and the fixing end plates11, respectively. The inner wheel frames40each comprise a belt41, a supporting ring42and a plurality of spokes43. The two ends of each of the spokes43are connected to a corresponding one of the belts41and a corresponding one of the supporting rings42. The belt41is fitted around the sleeve20.

The outer wheel frames30each have a fixing disk31, an outer ring32and a plurality of connection elements33. The connection elements33are connected to the fixing disks31and the outer rings32, respectively. In this embodiment, the connection elements33are rods with V-shaped cross-sections. The two ends of the connection elements33are fixed, by welding, for example, to the fixing disks31and the outer rings32, respectively, and arranged radially and annularly.

The fixing disks31are removably coupled to the fixing flanges21and the fixing end plates11, respectively. The fixing end plates11each have a plurality of first mounting holes111. The fixing flanges21each have a plurality of second mounting holes211. The fixing disks31each have a plurality of innermost apertures311corresponding in position to the first mounting holes111and a plurality of outermost apertures312corresponding in position to the second mounting holes211, respectively. Screws314are penetratingly disposed at the first mounting holes111and the innermost apertures311; hence, the outer wheel frames30are fixed to the fixing end plates11, respectively. Screws315are penetratingly disposed at the second mounting holes211and the outermost apertures312; hence, the outer wheel frames30are fixed to the fixing flanges21, respectively.

The sleeve20is cylindrical and thus is defined with an outer cylindrical surface. Wires (not shown) are wound onto the outer cylindrical surface of the sleeve20. Referring toFIG. 3, the inner wheel frames40are fitted around the sleeve20and spaced apart, such that spaces are formed between two adjacent inner wheel frames40and between each outer wheel frame30and its neighboring inner wheel frames40. Hence, the sleeve20has a plurality of spaces for receiving various wires. The inner wheel frames40are arranged equidistantly.

The outer cylindrical surface of the sleeve20has a plurality of third mounting holes201. Mounting holes411are disposed on the belts41of the inner wheel frames40and correspond in position, shape and quantity to the third mounting holes201. Screws412are penetratingly disposed at the third mounting holes201and the mounting holes411, respectively, to allow the inner wheel frames40to be fixed to the sleeve20.

Referring toFIG. 4andFIG. 5, in this embodiment, a protruding portion12and a positioning portion13are disposed at the two opposing ends of the shaft10, respectively, and correspond in position to the fixing end plates11, respectively. The fixing disks31each have a central hole313and a positioning opening317. When each outer wheel frame30is mounted at one end of the shaft10, the protruding portions12can penetrate the central holes313, respectively, and thus the positioning portions13can be engaged with the positioning openings317, respectively. In this embodiment, on the fixing end plates11at each end of the shaft, the protruding portions12are cylindrical and each have an axis which overlaps the axial line of the shaft10, whereas the positioning portions13come in the form of bumps and are adjacent to the protruding portions12. Furthermore, the innermost apertures311of the fixing disks31and the first mounting holes111of the fixing end plates11are configured in a manner to allow the innermost apertures311of the fixing disks31to correspond in position to the first mounting holes111of the fixing end plates11, respectively, when the positioning portions13are engaged with the positioning openings317, respectively. Hence, to mount the outer wheel frames30on one end of the shaft10, the user only needs to pass the protruding portions12through the central holes313of the fixing disks31, respectively, then allow the positioning portions13to get engaged with the positioning openings317, respectively, and eventually align the innermost apertures311of the fixing disks31with the first mounting holes111of the fixing end plates11, respectively.

In addition, in this embodiment, regarding the composite reeling device1, the fixing flanges21of the sleeve20each have a positioning slot212, whereas a positioning bump316is disposed on each of the fixing disks31corresponding in position to the fixing flanges21. The positioning bumps316correspond in shape and position to the positioning slots212for the sake of engagement therebetween. In this embodiment, the positioning bumps316protrude from the fixing disks31toward the sleeve20, respectively. Furthermore, the outermost apertures312of the fixing disks31and the second mounting holes211of the fixing flanges21are configured in a manner that the outermost apertures312of the fixing disks31correspond in position to the second mounting holes211of the fixing flanges21, respectively, when the positioning bumps316get engaged with the positioning slots212. Hence, the user mounts the outer wheel frames30on one end of the sleeve20to allow the positioning bumps316to get engaged with the positioning slots21, respectively, such that the outermost apertures312on the fixing disks31are aligned with the second mounting holes211of the fixing flanges21, respectively.

In this embodiment, regarding the composite reeling device1, the sleeve20has a positioning guiding groove202. The positioning guiding groove202is concavely formed on the outer cylindrical surface of the sleeve20and extends axially from one end of the sleeve20to the other end of the sleeve20. A positioning sliding bump413which protrudes is disposed on each of the belts41of the inner wheel frames40. The positioning sliding bumps413can slide along the positioning guiding groove202. In this embodiment, to mount the inner wheel frames40at one end of the sleeve20, the user slides the positioning sliding bumps413of the inner wheel frames40from one end of the sleeve20into the positioning guiding groove202, and then slide the inner wheel frames40axially to adjust their positions so as to align the mounting holes411of the belts41with the third mounting holes201of the sleeve20.

Referring toFIG. 6, in this embodiment, the composite reeling device1further comprises an adjustment unit50disposed on two adjacent inner wheel frames40to not only allow wires to be reeled but also adjust the perimeter of the windings of the wires according to the total length of the wires. For example, when the adjustment unit50is not mounted on the composite reeling device1, the wires are wound around the sleeve20, and in consequence the perimeter of the first winding of the wires equals the external perimeter of the sleeve20. However, when the adjustment unit50is already mounted on the two adjacent inner wheel frames40, the wires are wound around the adjustment unit50, thereby increasing the perimeter of the first winding of the wires. In case with a small total length of the wires, it is feasible to mount the adjustment unit50on two adjacent inner wheel frames40, such that the wires thus wound are close to the supporting ring42to enable easy access to the wires.

In this embodiment, the adjustment unit50comprises a plurality of rods51. The two ends of each rod51are coupled to spokes43of the two adjacent inner wheel frames40. Referring toFIG. 7, each spoke43has a plurality of positioning holes431arranged lengthwise and neatly. The rods51are fastened to the positioning holes431with screws52. Hence, depending on the intended perimeter of the windings of the wires, the rods51are selectively fastened to the intended positioning holes431of the spokes43. For instance, the rods51fastened to the outermost positioning holes431achieve a larger perimeter of the first winding of the wires than the rods51fastened to the innermost positioning holes431.

Therefore, in this embodiment, regarding the composite reeling device1, a plurality of inner wheel frames40define a plurality of spaces for receiving the wires of different types to thereby enhance ease of use. In this embodiment, the composite reeling device1has some other advantages: the shaft, sleeve, outer wheel frames and inner wheel frames can be removed during a storage process and a transport process so as to be stored and stacked separately. Unlike the prior art, the present invention has important advantages as follows: storing more composite reeling devices in a space of a specific volume, increasing the storage space utilization rate, and using less vehicles required for transport. Furthermore, in this embodiment, the composite reeling device1is equipped with the adjustment unit50for adjusting the perimeter of the windings of the wires.
