Fig. 17 is a schematic view similar to the view shown in Fig. 8, and information related to how the implementation shown in Fig. 16.
Quick-coupling device shown in Fig.1, contains two parts 1, 2. The first part 1, which forms the body of the gear, pivotally connected by a pin 3 with the end of the boom 4 excavator or loader, and it has the ability to rotate around this axis under the concerted action of the two levers 5, 6, driven by a piston rod 7 of a conventional hydraulic power cylinder.
The second part 2 is fixed on the attachments 8, representing in this case the bucket.
In accordance with another variant of realization of the bodies forming the second part may constitute an integral part of this attachment.
In the most simple variant of realization of the second part 2 is made in view of the part having the form of a bracket and secured in its middle part on the surface 8A of this attachment. Both branches of the brackets are connected by a pin 9, and its middle part is uhodit in the direction opposite with respect to axis 9.
The first part 1, forming the body of the mesh contains lodgement 13, forming a hook, and provides for the raising of this wall-mounted equipment, the axis 9 which is located in the cradle, as shown in Fig. 8.
In accordance with one possible implementation of the present invention, the first part 1 is made essentially in the form of staples through the lateral branch which passes, in particular, the axis 3.
The middle part 1A part 1 contains the cutout 14, through which can pass the item 10 during the rotation of this part 1 of the body around the axis 3.
In this implementation, the upper portion of the part 10 forms a stop 15 that can, in his meeting with the swing finger 16 to release the plate 17 of the lock, which is able to slide on the middle part of the first part 1 in order to come under the ledge 12.
In accordance with one possible implementation plate 17 includes a neck 18, which can essentially be flush with the recess 14 in the case when the plate 17 is in its “cocked” position, i.e. the position, in particular, is schematically shown in Fig. 2.
The plate 17 is constantly exposed to utilisatio this effort is realized by means of two springs 19 (Fig. 3).
There is a special tool to hold the plate 17 in its cocked position.
Thus, the plate 17 is held in its cocked position by means of the finger 16 of the lock. As shown in the figures, the finger 16 is hinged by one of its ends over the middle part 1A so that under the action of its weight, he tried to turn in the direction of the middle part and stay in this position. Based on the precautionary principle, this effect can be reinforced by special action of a spring (not shown).
The finger 16 includes a part made in the form of ledge 20, which rests against a corresponding surface of the plate 17, and contains, outside of this part in the form of a ledge, part 21, which passes over the neck 14.
The process of engagement in this case is as follows.
The resulting displacement of the boom 4 and the piston rod 7 capture attachments 8 and raise it to translate in the position shown in Fig. 6.
Then perform the rotation of the first part 1 in the direction shown by the arrow F1 by extension of the piston rod 7. In the process of making this movement the stop 15 meets along the way made esteem its return spring is under the tab 12 ( Fig. 8), and part 1A part 1 this rests with its lower surface in the surface 11 of the second part 2.
In this variant implementation of the protrusion 12 and the stop 15 are an integral part of the workpiece 10. However, these two functions can be performed in two different bodies.
Guiding device for a plate 17 does not create any problems, and it is schematically presented in figures rails 22.
The contact between the protrusion 12 and the plate 17 of the lock is performed by surfaces inclined relative to the direction of movement of the said plate.
As shown in the figures, the plate 17 block has a beveled edge on his part 23, which should go under the ledge 12. In accordance with a possible option for this part forms with the bottom surface of the plate 17, the angle having a magnitude of about 7°.
Similarly, the surface 12A (Fig. 8) of the protrusion 12, which must be in contact with part 23, forms an angle identical to the angle of the support surface of the adapter and formed by the surfaces 11. Thus, the body engagement pressed tightly against the adapter under the action of efforts to develop the said springs, which tend PI, which allows you to refuse the use of the finger lock. Under the force, which tends to displace the plate 17, the plate is pressed against the stop 24 and partially closes the slot 14.
The ledge 12 includes at its end inclined surface 25. During the rotational movement of the first part 1 of the upper part of the inclined surface 25 comes into contact with the edge 26 of the recess 18 of the plate of the lock and moves the plate, opposing force, which acts on the plate, in particular, in the direction shown by the arrow F2. At the end of the above-mentioned rotational motion of the end of the projection 12 is located above the notches 18, and the plate under the influence of the current on her efforts included under this ledge.
The said finger lock can be replaced by a hydraulic power cylinder (not shown).
In some cases, manual release may be preferred, and next will be described the combination of means providing for the possibility of its implementation.
It is clear that to detach this mounted equipment necessary to move the plate lock in the direction shown by the arrow F2.
For this purpose the free end of the plate 17, the opposite 3. This design decision allows to use the tool 29 (Fig. 12) containing the handle 30 and having at one of its ends two fingers 31 and 32, and the finger 31 has two diametrically opposite trunnion 33.
In the process of introducing these pins in the slots 28 of the lower finger 32, which has the appropriate size parameters, rests on the surface of the middle part 1A part 1.
When it becomes clear that providing rotation of the handle 30 in the direction shown by the arrow F3, can result in the movement of the plate 17, which is moved in the direction shown by the arrow F2.
In accordance with the proposed invention also provides means intended to counteract the formation of gaps between parts 1, 2 and compensate for these gaps when they occur.
In accordance with a variant implementation of the invention, as schematically shown in Fig. 15 referred to the adapter contains two edges 34 perpendicular to the axis 9, and the surface 35 of these edges machined in such a way as to be in the shape of the letter V. the Middle part of the body gearing includes a plate 36, the surface 37 which score is when the two parts 1, 2 come into contact with each other, the first part 1 is still fixed in the transverse direction relative to the second part 2, and Vice versa.
Needless to say that the machining required for the implementation of the surfaces 35, 37, can be performed directly on the surface 11 of the second part and on the surface of the middle part 1A part 1.
Next with reference to Fig. 16 and 17 will be described another embodiment of the means providing the opportunity to hold the plate 17 in its cocked position.
In accordance with the invention the middle part 1A contains on its surface, which rests against the plate 17 of the lock, a small stop 38, which is pressed end 17A mentioned plate under the action of springs 19 in the case when it is provided, in essence, matching notches 14 and 18.
In this embodiment, the implementation of the said spring also perform the function of the pressing plate 17 to part 1A, and only one pair of rails 22, as shown in Fig.16 and 17, in this case, useful. Here there is a significant gap between the guide and the upper part of this plate 17.
The upper portion of the part 10 opposite to the protrusion 12, contains the ledge 39.
In the case when asanam arrow F1, the end 17A of the plate lock meets on his way ledge 39, causing uplift. Indeed, the plate 17 is slightly rotated in the reverse direction, abutting the edge portion 1A and flexing every spring 19 in the plane of its longitudinal axis. As a consequence, the end 17A passes over the stop 38 and, under the action of springs 19, which in this stretch, the plate 17 occupies the position which is shown in Fig. 17.
To facilitate the transition plate 17 from its position shown in Fig. 17, in the position shown in Fig. 16, the stop 38 includes behind his support surface 38 and the inclined surface 38b.
A set of hand tools, described above with reference to Fig. 10 - 14 and designed to unlock this device, gearing, can also be used in regard to the implementation shown in Fig. 16 and 17, and noted that in this case, the finger 31 is pivotally secured to the handle 30.

Method for robotic destruction of post-earthquake collapsed structures // 2553692
FIELD: medicine, life-saving equipment.
SUBSTANCE: refers to equipment for saving the people under collapsed structures. Concrete is destructed fast by section, extension, and cyclic actions. Mechanisms are equipped by powerful reciprocating cyclic hydraulic actuators for column concrete jacking, crushing and wedging and reinforcement stripping by reinforce cutters, e.g. friction disks. A bulldozer blade is equipped with steel durable horns and a pair of powerful hydraulic mountings. A jib-type crane has three telescopic levers mounted on the vehicle. One of the telescopic crane levers is provided with a riveting brace and a powerful pulsating jack actuating a steel hydraulic tooth, whereas the second one has a hydraulic claw. The bulldozer is driven to a collapsed structure. That is followed by anchoring the bulldozer; the longitudinal horn travel is actuated, and sliding along the ground bed pushes the horn by the pulsating jack underneath the collapsed column. Cyclic oil feed into the hydraulic mountings is actuated, and the collapsed column is lifted 1 or 2 metres higher. The lever with the hydraulic claw is led to the column; a shaft is gripped tightly; the collapsed column shaft concrete is crushed in the cyclic mode for the reinforcement stripping. As may be required, remote control enables leading the second lever to the column; the riveting brace is put on the column shaft; the hydraulic tooth is actuated to pulsate by remote control to crush the concrete. The third lever is led to the stripped reinforcement. One of the devices is used to cut the stripped reinforcement with securing the column shaft not to fall down with the hydraulic claw. The cycles are repeated with the second column end gripped by the collapsed structure; the separated piece of the structure is removed and taken away from the obstruction site to the dumping ground or onto the vehicle; then the cycles are repeated, and the obstruction site is cleared by removing all the collapsed structures.
