[0002] In the warehouse field, the goods shelf as the core equipment of bearing goods, its hoisting safety directly influences operation efficiency and personnel safety. At present, the conventional connection mode of goods shelf and lifting ring generally adopts welding process, and the lifting ring is directly welded on the surface of goods shelf stand or crossbeam. Although welding has the advantages of high connection strength and low cost, but this mode has significant defects:

[0003] 1, fixedly not detachable. Welding makes the lifting ring and the goods shelf form permanent rigid connection, and cannot be separately disassembled and checked or replaced. When the lifting ring appears wear, crack or rust due to long-term load, the weld seam needs to be cut and welded again, so that the maintenance cost is high and the structural integrity of the goods shelf is damaged.

[0004] 2, hidden damage is difficult to detect. The welding area is prone to fatigue cracks due to stress concentration, but when the weld surface is covered with coating or rust, visual inspection cannot find internal defects, and professional equipment such as ultrasonic and magnetic particle inspection is needed, which increases the difficulty and cost of daily inspection.

[0005] 3, poor adaptability. The welding process has high requirements for the material (such as steel, aluminum alloy) and structure of the goods shelf. If the thermal expansion coefficient of the lifting ring and the goods shelf material is large, the connection may fail due to inconsistent deformation under extreme temperature.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example

[0022] A type of heavy-duty lifting rack, such as Figure 1 As shown, the shelf body includes a shelf main body, which includes a load-bearing component 100 for placing items and a support component 200 disposed on the load-bearing component 100 for supporting the load-bearing component 100. The shelf main body is provided with a lifting component 300 for cooperating with a lifting device. The lifting component 300 includes a disassembly part 310 connected to the shelf main body and a lifting part 320 connected to the lifting device, as shown. Figure 2As shown, the dismounting part 310 has a cylindrical accommodating cavity 311, one end of the accommodating cavity 311 is provided with a through hole 312, the shelf body is provided with a plurality of insertion rods inserted into the through hole 312, the end of the accommodating cavity 311 close to the through hole 312 is arc-shaped, the end of the accommodating cavity 311 close to the through hole 312 is provided with at least two partitions 313 arranged in a circumferential array around the central axis of the accommodating cavity 311, the partitions 313 are arranged along the length direction of the central axis of the accommodating cavity 311, the adjacent two partitions 313 form a mounting area, the mounting area is provided with a ball 314, the distance between the two sides of the adjacent two partitions 313 close to the central axis of the accommodating cavity 311 is smaller than the diameter of the ball 314, the middle of the accommodating cavity 311 is provided with a sleeve ring 315 which can be sleeved on the outside of the insertion rod, the outer periphery of the sleeve ring 315 is provided with a limiting plate 316 corresponding to the ball 314, the limiting plate 316 is located on the side of the ball 314 away from the through hole 312, the sleeve ring 315 and the end of the accommodating cavity 311 away from the through hole 312 are connected by a spring 317, the outer periphery of the part of the insertion rod inserted into the through hole 312 is provided with an arc-shaped part matched with the ball 314, the limiting plate 316 and the ball 314 are both made of steel material with magnetic conductivity.

[0023] In order to realize the quick dismounting of the lifting part 300 and the shelf body, so as to check or replace the lifting part 300, the lifting part 300 is divided into two parts, the lifting part 320 is used to connect the lifting device, and the dismounting part 310 is used to connect the shelf body. When the dismounting part 310 is connected with the shelf body, the through hole 312 is aligned with the insertion rod, the insertion rod is inserted into the through hole 312, and the insertion rod cannot be continuously inserted, so as to ensure that the arc-shaped part of the insertion rod is completely inserted into the accommodating cavity 311 and matched with the ball 314. After the insertion rod is inserted into the through hole 312, if the dismounting part 310 is pulled, the limiting plate 316 will always be pushed to the end of the accommodating cavity 311 close to the through hole 312 under the action of the spring 317, so that the ball 314 is always close to the through hole 312. When the arc-shaped part of the insertion rod also moves to the end of the accommodating cavity 311 close to the through hole 312, the ball 314 will be trapped in the arc-shaped part of the insertion rod, and the ball 314 will be clamped in the arc-shaped part of the insertion rod under the cooperation of the limiting plate 316 and the arc-shaped area of the end of the accommodating cavity 311 close to the through hole 312, so that the insertion rod cannot be continuously separated from the through hole 312, thereby ensuring the connection between the dismounting part 310 and the insertion rod. When the dismounting part 310 needs to be dismounted, a strong magnet is only needed to be used at the end of the accommodating cavity 311 away from the through hole to adsorb the limiting plate 316 and the ball 314, so that the ball 314 is separated from the arc-shaped part of the insertion rod, and then the dismounting part 310 can be easily taken off from the insertion rod. The partitions 313 can isolate the balls 314 from each other, so as to avoid the mutual influence between the balls 314 in some extreme cases, so that the balls 314 cannot be smoothly positioned into the arc-shaped part of the insertion rod.

[0024] Of course, even if the ball 314 is trapped in the arc-shaped part of the plug, it only prevents the tumbler from coming out of the insertion hole 312, but cannot prevent the plug from being inserted further, which may cause shaking during lifting. Therefore, a ring-shaped baffle can be arranged on the side of the arc-shaped part of the plug close to the rack body to prevent the plug from being inserted further into the insertion hole 312 during lifting, which may cause shaking. As long as the distance between the baffle and the arc-shaped part is controlled, the ball 314 can be stabilized in the arc-shaped part of the tumbler after the plug is inserted, and there is no need to pull the plug back to confirm. Further, in order to buffer the vibration caused by the machine during lifting, a rubber cushion can also be arranged on the side of the baffle close to the arc-shaped part of the plug. When the plug is inserted in place, the cushion remains in contact with the outer side wall of the accommodating cavity 311 of the disassembling part 310.

[0025] In order to further reduce the shaking during lifting, the height of the lifting part 300 is higher than the height of the carrier 100, so that the lifting part 320 is higher than the stress point of the carrier plate.

[0026] In the case of ensuring sufficient strength, the structure is simplified as much as possible to save costs. The carrier 100 is a rectangular plate, the support 200 is a support leg arranged at the four corners of the carrier 100, and the bottom of the carrier 100 is connected with the support 200 through a reinforcing rod 400 for preventing the mutual loosening between the support 200 and the carrier 100. Of course, a reinforcing rod can also be further added between adjacent supports 200 to further strengthen the structural strength.

[0027] In order to prevent the force applied by the tumbler to the goods along the axial direction during lifting, the plug is arranged horizontally on both sides of the carrier 100, so as to avoid the plug applying force to the disassembling part in the axial direction during lifting, which may cause long-term damage to the arc-shaped surface of the accommodating area, the ball 314 and the arc-shaped part of the tumbler.

[0028] The above heavy lifting rack can also be combined into a heavy lifting rack group, as shown in Figure 3 As shown, a plurality of heavy lifting racks as described in any of the above are stacked from bottom to top through the support 200. The stacking of the plurality of racks forms a rack group, which can save floor space, and the reinforcing rod 400 of the upper rack can also serve as a guardrail for the lower rack to prevent goods from falling. The uppermost rack can be additionally provided with a guardrail around the carrier plate.

[0029] In order to prevent the stacked racks from moving relative to each other and increase the stability of the stacking, the support 200 of the upper rack body is clamped between the support 200 of the adjacent lower rack body. Specifically, a clamping groove can be formed at the bottom of the support 200 of the upper rack, and during installation, the clamping groove of the support 200 of the upper rack is wrapped around the top end of the support 200 of the lower rack to achieve clamping.

[0030] The above-described embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
