[0002] In the motor maintenance industry, due to the wide variety of motors and their different sizes, especially after disassembly, a large number of loose parts are generated, and both the placement and site usage are very messy and inefficient.

[0003] There are usually two ways of storage in the warehousing industry: one is a highly automated stacking warehouse shelf, and the other is to place items on the shelf by manually operating a stacker. Both types of shelves require items to be placed on pallets, and then the pallets and items are placed on the shelves by equipment such as forklifts. Due to the limitation of the fixed size of the pallet, the actual space utilization rate of the shelf is not high, and it is not suitable for the efficient storage of motors and their components in the above-mentioned motor maintenance industry.

[0004] Chinese patent document CN208217602U discloses a trolley-type drawer storage cabinet for warehousing, which overcomes the defects of traditional drawer-type storage. The drawer can store heavy objects through the trolley load-bearing, and does not need a forklift to transport, thereby improving the flexibility and diversity of drawer-type storage. However, due to structural limitations, this trolley-type drawer-type container is only suitable for storing light objects, and is not suitable for storing heavy objects. Summary of the invention

The guide rails 2 are symmetrically arranged at both sides of the interior of the shelf body 1 in the vertical direction, and load-bearing blocks 21 and rear stoppers 22 are respectively provided at both ends of the guide rails 2. Rollers 31 are arranged at intervals on both sides of the rear part of the bottom surface of the pallet 3, load-bearing surfaces 32 are arranged at intervals on both sides of the front part, and a traction block 33 is arranged in the center of the front. The pallet 2 is located on two guide rails 2 on the same horizontal plane, and the rollers 31 on the bottom surface of the pallet 3 slide along the guide rails 2, and the load-bearing blocks 21 and the rear stoppers 22 respectively limit the sliding of the rollers 31. When the pallet 3 is closed on the shelf body 1, the load-bearing surface 32 is located on the load-bearing blocks 21. The forklift 4 is located on the front side of the shelf body 1, and a traction slot 42 is provided on the surface of the shovel arm 41, and the traction slot 42 matches the traction block 33 on the bottom surface of the pallet 3.

[0013] Preferably, Figure 5 As shown, a slide-stopping protrusion 34 is provided on the load-bearing surface 32 of the bottom surface of the tray 3 , and the slide-stopping protrusion 34 matches the load-bearing block 21 of the guide rail 2 .

[0014] Preferably, the forklift 4 is a hydraulic forklift or an electric forklift.

[0015] like Figure 6 As shown, a method for using the heavy-duty drawer-type shelf comprises the following steps: Step 1: When storing items, the forklift 4 moves to the front side of the shelf body 1, the shovel arm 41 extends to the bottom surface of the selected pallet 3, and the traction card slot is inserted into the traction block on the bottom surface of the pallet, and the shovel arm 41 is lifted to raise the load-bearing surfaces on both sides of the front of the pallet, detach from the top surface of the load-bearing block of the guide rail and hang in the air, and the front of the pallet 3 is supported by the shovel arm; Step 2: The forklift 4 moves backward and moves the pallet 3 out along the guide rail through the traction slot. The rollers on the bottom of the pallet slide along the guide rail until they hit the load-bearing block and stop. The pallet 3 is located outside the front side of the shelf body 1. Step 3: Light objects can be carried in or out of the pallet 3 by manpower, and heavy objects 5 can be lifted in or out of the pallet by a sling 6 using a crane; Step 4: After the items are placed or taken out, the forklift 4 moves forward to move the pallet 3 back into the shelf body 1, and then lowers the shovel arm 41 to make the load-bearing surfaces on both sides of the front of the pallet 3 abut against the load-bearing blocks, and the pallet 3 is reset to complete the storage operation of the items.

[0016] Preferably, when the pallet is reset in step 4, the anti-slip protrusion on the load-bearing surface of the bottom surface of the pallet is elastically clamped on the rear part of the load-bearing block to prevent the pallet from sliding outward.

[0017] This heavy-duty drawer-type shelf is equipped with multi-layer rails on the shelf body, with double roller trays on the rails. The double rollers are placed on the bottom surface of the rear end of the tray, and the lower part of the front end of the tray is placed on the load-bearing block of the shelf. When in use, drive the forklift to the front end of the tray, extend the shovel arm into the bottom of the tray, raise the front end of the tray, separate it from the load-bearing block, and then back off the forklift to pull the tray out of the shelf body. Then use the crane to lift the heavy objects in the tray in or out. After lifting and placing, the forklift can be reversed to push the tray into the shelf body and reset it, thereby realizing convenient and efficient storage of items.

[0018] Usually, the existing heavy-duty shelves can only hold one pallet, and one object is placed on the pallet. If the objects are of different sizes, it will cause a waste of area. However, the present invention can place all objects in a pallet regardless of size, maximizing the use of the pallet area. In addition, the forklift of the present invention only bears half the weight of the pallet and the objects therein, and the rollers at the bottom of the pallet serve as another fulcrum, so the shovel arm and the roller arm at the bottom of the forklift can be shortened, so that the floor space required for the forklift to move forward, backward and turn can be saved, and about one-third of the floor space can be saved compared to the same type of electric or hydraulic forklifts that match the existing heavy-duty shelves. The shelf structure can be hoisted by a traveling crane to place heavy objects weighing hundreds of kilograms to several tons, and can be used as heavy-duty storage equipment.
