Title: Plane storage and transportation unit of a stereoscopic warehouse with four-direction movable goods allocations

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to the storage field such as stereoscopic warehouse and stereoscopic parking and the filed such as furniture storage and home improvement, and in particular, to a plane storage and transportation unit of a stereoscopic warehouse with four-direction movable goods allocations. 
     2. Description of the Related Art 
     The prior stereoscopic warehouse can be divided into the unit-goods-type stereoscopic warehouse, the through-type stereoscopic warehouse, the automated cabinet-style stereoscopic warehouse, the stripe shelf stereoscopic warehouse, etc., according to the shelf structure thereof. According to the type of machinery for loading goods in the stereoscopic warehouse, it can be divided into the shelf forklift stereoscopic warehouse, roadway stacker stereoscopic warehouse, etc. Regardless of the form, the stereoscopic warehouse has a common shortcoming: the goods allocation itself cannot be moved. The goods access depends on the forklift or the stacker that must operate in the direction of the goods entering and leaving the goods allocation. This limits the depth of the arrangement of the goods allocation: the depth of the goods allocation can only be two. The standard model thus arranged is that the two goods allocations are arranged back to back in a storage unit, and a channel is provided between each two storage units for the forklift or the stacker to access the goods. Even if some stereoscopic warehouses can be moved, the moving direction is only two-way movement, and it is impossible to move in four directions in each plane. The stereoscopic parking garage has lifting and traversing type, vertical circulation type, simple lifting type, vertical lifting type, plane moving type, roadway stacking type, multi-layer circulation type, horizontal circulation type, and car lifting type. Regardless of the form, the stereoscopic parking garage has a common shortcoming: the moving direction of the parking space is mostly two. At most, the local parking space can realize three-way moving in the plane. It is impossible to move in four directions for each parking space. The above characteristics cause the low space utilization rate of the existing stereoscopic warehouse and parking garage. 
     The prior home storage facilities, regardless of cabinets, bookcases, lockers, and sundries cabinets, are visible and convenient for accessing goods, and are divided into numerous small storage spaces, resulting in numerous openings for the cabinet to access goods. It is necessary to leave an operation channel for accessing goods on the opening side of the cabinet, which is the same as the setting of the prior stereoscopic warehouse, and the space utilization efficiency is low. On the other hand, there are many openings for the cabinet to access goods, which need to be covered by the corresponding cabinet doors. Not only the decorative effect is poor, but the sealing is not good, dust is easy to be accumulated, and the anti-theft function is weak. Space that is higher than two meters basically cannot be used as storage space, because manual access is more difficult, and assist climbing tools are required; the space utilization rate is low, dust is easy to be accumulated at the top of the cabinet, and is not easy to be cleaned. Foremost, everyone has the experience that you cannot find something you want; it is difficult for the prior furniture storage to store files intelligently, and the files cannot be accessed automatically.

     This plane storage and transportation unit of a stereoscopic warehouse with four-direction movable goods allocations is used as the basic component of the horizontal or vertical storage and transportation plane of the stereoscopic warehouse or parking garage, and the vertical or horizontal storage and transportation channel vertical to its working plane can be supplemented; for instance, the plane storage and transportation unit of a stereoscopic warehouse with four-direction movable goods allocations is used as the basic component, namely, the storage and transportation layer, of horizontal or vertical storage and transportation plane of the stereoscopic warehouse or parking garage, and if the lifting device is supplemented in the vertical direction, numerous storage and transportation layers can be assembled into a complete stereoscopic warehouse or parking garage. Basically, all available space can be set into the goods (vehicles) position, and the space utilization rate is high. The advantages in ship loading, old building renovation and underground parking lot construction are obvious. It is also suitable for intelligent control; the storage location of the goods (vehicles) is controllable, the positioning is good, the access efficiency is high, and the anti-theft performance is good. For the always changing access needs, the location of the goods (vehicles) can be adjusted at any time to achieve goods (vehicles) access at the fastest speed. For example, in the “Double 11”, a day when Chinese people go on massive Internet shopping sprees because many online stores offer huge discounts on this day, the shipment rate of a certain product increases sharply during a certain period of time; the intelligent control system can control the proper concentration of such goods in the whole warehouse to the pick-up window, which will greatly reduce the workload and improve the shipping efficiency, and this is difficult to be achieved in the traditional stereoscopic warehouse system. Another example is that: consumers go to a large mall for shopping and entertainment, while the car is parked in Area A and the consumption ends in Area F, the two places are far apart, and customers have to get the car at where the car is parked in the prior parking lots. The stereoscopic parking garage composed of this plane storage and transportation unit of a stereoscopic warehouse with four-direction movable goods allocations can be provided with one or several access entrances as needed, and the vehicles allocation is movable, hence, off-site getting the car nearby or even the car moves in the same direction as the owner moves can be completely realized. 
     This plane storage and transportation unit of a stereoscopic warehouse with four-direction movable goods allocations has broad application prospects in library collections, archives archiving, collection of museum collections, and storage of the goods. It not only has the similar advantages described above. If the functions such as temperature and moisture control, prevention of biological damage, fire prevention and theft are to be achieved in the traditional warehousing, it is basically aimed at the building envelope structure or the separation structure of the building space, because the entire storage system requires too many access passages, and it is difficult to achieve the centralized and sealed storage. The invention can be only provided with one or a few controllable access channels to store the stored goods in a centralized manner, and to reduce the space of the environment control, so that a more optimized storage environment can be provided under the premise of being economical, effective and controllable. At the same time, because the environmental space is controlled to be compact, the cost for environmental control and preservation is lower, the energy consumption is less, and it is more energy-saving and environmental-friendly. With the supplementary of the intelligent system, it is extremely convenient to record the date, content, storage location and other information for the electronic file of the stored goods; it is extremely convenient to search information and access goods, and it is easier to be implemented and more efficient in automated management of collection status monitoring, environmental status monitoring, and accident alarms. 
     Due to the heavy dust in northern China, the cabinets, bookcases, lockers, sundries and other furniture used in the traditional household storage are poor in dustproof performance; this plane storage and transportation unit of a stereoscopic warehouse with four-direction movable goods allocations can be used as the storage cabinet under the cabinet or the tatami, and it can be completely sealed and has good dustproof performance. In southern China, the environment is humid and the biological damage is serious. This plane storage and transportation unit of a stereoscopic warehouse with four-direction movable goods allocations can be used as the storage space and can be completely sealed; the temperature and humidity can be controlled to prevent mildew; measures to kill pests can be used in the space without worrying about affecting human health. The prior architectural concrete frames and steel structural frames are becoming more and more widely used, and has become the mainstream, which brings an issue that whether the space occupied by the partition wall in the room can be changed into the storage space. And at the same time, it has the function of storage and separation, and the space utilization rate is higher, which makes the room neater. The idea is good. However, the problem is that the current furniture has two problems as a partition wall: the open cabinets without cabinet doors are not soundproof, and all cabinets for all purposes are not suitable to be set as non-door structure; while when the cabinet doors are provided, it is unsightly that the cabinet doors are everywhere; even if there is a gap, it is not beautiful for aesthetic purposes, and the overall decoration style of the room is not easy to be coordinated; moreover, if the cabinet doors are provided, other furniture cannot be placed in front of the cabinet wall, otherwise the furniture needs to be moved and the space utilization rate is low. This plane storage and transportation unit of a stereoscopic warehouse with four-direction movable goods allocations can be used as the storage space, and only a small opening for accessing goods is needed in an unobtrusive position, such as behind a door; and when it is used as the bookcase, even an opening of the size of the book section is required. Accordingly, the walls on both sides of the cabinet can be integrated, the wall is seamless, and it is easy to be coordinated with the overall decoration style and to handle sound insulation problems, the structural strength is higher, the anti-theft effect is good, and the room is neater and more orderly. Because the upper space of the room is utilized, the space utilization is more efficient and more goods can be stored. Foremost, with the supplementary of the intelligent system, the electronic file of the goods can be created when storing the goods to record the date, content, storage location and other information, which can be searched at any time; with one click for accessing goods, there will be no troubles to find goods, which meet the needs for smart home. 
     The technology can also be applied to display museum collections, artworks, jewelry, clothing and other display systems. The exhibition arrangement and removal are convenient and fast, and the display position of the exhibits can be changed during the exhibition process.
