Description

Technical Field

[0001] The present application relates to the technical field of pallets, and in particular to a pallet for a three-dimensional warehouse. Background Art

[0002] Three-dimensional warehouse pallets are used to facilitate cargo loading and unloading, transportation, storage and distribution. Most three-dimensional warehouse pallets are loading and unloading pads composed of a load surface that can carry a certain number of items and a forklift socket. In order to meet the needs of cargo of different shapes, other pallets with accommodating cavities will also appear, such as U-shaped pallets for placing steel pipes. Pallets are the most inconspicuous but ubiquitous logistics equipment in the logistics industry. They are the main means of converting static cargo into dynamic cargo.

[0003] Currently, most pallets are made of welding and have a simple structure and high strength. However, after production, if they are damaged, they need to be replaced as a whole, which wastes resources. Moreover, the size cannot be changed after production, so usually a variety of pallets of different specifications are made to meet the use of different goods. For longer pallets, part of them will be suspended in the air due to the forklift socket at the bottom. When carrying heavy goods, it is easy to cause local deformation of the suspended part, which may affect the use function and safety.

[0004] Based on the above-mentioned defects, how to develop a pallet for a three-dimensional warehouse with adjustable size and improved support strength is a technical problem to be solved by this application. Utility Model Content

[0005] In view of this, the present application provides a pallet for a three-dimensional warehouse, which can be used in combination with an extended pallet part and / or reinforced legs and a pallet carrier body to solve the technical problems that the existing pallet size cannot be changed and the suspended part cannot increase the supporting strength.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pallet for a stereoscopic warehouse includes a pallet carrier body, wherein the pallet carrier body includes a U-shaped frame formed by welding a plurality of square tubes, the bottom of the U-shaped frame has a fork channel, a steel skin layer is laid in a concave cavity of the U-shaped frame, and the surface of the skin layer is sprayed with plastic.

[0008] Furthermore, a detachable extended tray portion is connected to at least one end of the tray carrier body.

[0009] Furthermore, a first limit locking mechanism is provided on one side of the extended pallet part, and the first limit locking mechanism includes a boss and a locking plate rotatably arranged on the boss, and the boss cooperates with a mounting hole located on the corresponding first leg of the pallet carrier body, and the locking plate is rotated to hook with the corresponding first leg to prevent the extended pallet part from separating from the pallet carrier body.

[0010] Furthermore, a sliding rod is provided on the boss, and the locking plate is rotatably arranged on the sliding rod. A first return spring sleeved on the sliding rod drives the sliding rod to move, and can drive the locking plate to automatically press against the corresponding first leg or the boss.

[0011] Furthermore, a limiting groove for limiting the locking piece is provided on the corresponding first leg.

[0012] Furthermore, the boss is provided with a positioning groove extending in the transverse direction, and after the locking piece is rotated to a corresponding angle, it can enter the positioning groove and be locked in position under the action of the first return spring.

[0013] Furthermore, it also includes at least one reinforcing leg, which is detachably installed in the fork channel.

[0014] Furthermore, the reinforced leg includes a leg body that is abutted against the bottom surface of the U-shaped frame, and the top surface of the leg body is provided with at least two limit blocks that can respectively abut against the corresponding square tubes, and the second limit locking mechanism arranged on the limit block can act on the corresponding square tube to achieve locking of the reinforced leg.

[0015] Furthermore, the second limiting locking mechanism includes a locking rod slidably arranged on the limiting block and a second return spring sleeved on the locking rod, and the locking rod can be automatically inserted into the limiting hole located on the corresponding square tube under the action of the second return spring.

[0016] It can be seen from the above technical solution that the advantages of the utility model are:

[0017] 1. The pallet carrier body in the present application includes a U-shaped frame and a skin layer. The provision of the skin layer can reduce the wear of the U-shaped frame, and the service life of the present application can be extended by replacing the skin layer.

[0018] 2. In the present application, a pallet carrier body and an extended pallet portion detachably connected to the pallet carrier body are provided, and the size of the pallet is adjusted by adjusting the number of extended pallet portions used.

[0019] 3. The present application also provides a reinforced support leg that can be detachably connected to the pallet carrier body. The reinforced support leg is used to increase the support strength of the suspended portion of the pallet without affecting the coordinated use of the pallet and the forklift.

[0020] 4. The first limit locking mechanism and the second limit locking mechanism in the present application have simple structures, which makes it convenient to disassemble and assemble the extended pallet part and the reinforced legs, and minimizes the impact on the strength of the pallet carrier body.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the implementation modes and the accompanying drawings. Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.

[0033] refer to Figures 1 to 9 ,like Figure 1 As shown, this embodiment provides a pallet for a stereoscopic warehouse, including a pallet carrier body 1, the pallet carrier body 1 includes a U-shaped frame 11 made by welding multiple square tubes, the bottom of the U-shaped frame 11 has a fork channel 112, and a steel skin layer 12 is laid in the concave cavity of the U-shaped frame 11, and the surface of the skin layer 12 is sprayed. The U-shaped frame 11 made by welding multiple square tubes vertically and horizontally has a simple manufacturing process and is light in weight. The setting of the skin layer 12 can not only serve as a cover, but also prevent the goods from directly contacting the U-shaped frame 11 and causing wear of the U-shaped frame 11. The skin layer 12 can be replaced separately after being damaged, which can reduce the equipment loss cost.

[0034] like Figure 2 and Figure 3 As shown, at least one end of the pallet carrier body 1 is connected to at least one detachable extension pallet portion 2. The extension pallet portion 2 can be used to extend the length of the pallet, thereby achieving size adjustment, making it convenient to use goods of different sizes. When the pallet carrier body 1 is flat, the extension pallet portions 2 can be installed on all four sides of the pallet to achieve adjustment of the length and width of the pallet, and also avoid the problem of high idle rate of pallets of various specifications.

[0035] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a first position-limiting locking mechanism 22 is provided on the outer side of the corresponding second leg 21 of the extended pallet part 2, and the first position-limiting locking mechanism 22 includes a boss 221 and a locking piece 223 rotatably arranged on the boss 221, and the boss 221 cooperates with the mounting hole 113 located on the corresponding first leg 111 of the pallet carrier body 1, and the locking piece 223 is rotated and hooked with the corresponding first leg 111 to prevent the extended pallet part 2 from being separated from the pallet carrier body 1. The cooperation between the boss 221 and the mounting hole 113 provides support for the extended pallet part 2, so that the extended pallet part 2 can be reliably installed and bear a large load.

[0036] Specifically, the first leg 111 is formed by two vertical leg columns and a crossbeam transversely connected between the two leg columns, the mounting hole 113 is formed between the two leg columns, the crossbeam and the table top, and the locking piece 223 is rotated and hooked with the crossbeam to prevent the boss 221 from separating from the mounting hole 113.

[0037] In a specific embodiment of the present application, the boss 221 is formed by welding a square tube and the second leg 21, and a sliding rod 222 is also provided on the boss 221. The locking plate 223 is rotatably set on the sliding rod 222. The first return spring 224 mounted on the sliding rod 222 drives the sliding rod 222 to move, and can drive the locking plate 223 to automatically press against the corresponding first leg 111 or the boss 221.

[0038] Specifically, an end block connected by a thread is respectively provided at both ends of the sliding rod 222, and the two end blocks are respectively located on both sides of the boss 221. One end block is used to limit the locking plate 223, and the other end block is used to limit the first return spring 224. The first return spring 224 is supported between the corresponding end block and the boss 221. The first return spring 224 is used to increase the friction between the locking plate 223 and the boss 221, so that the locking plate 223 is not easy to rotate at will.

[0039] In a specific embodiment of the present application, a limiting groove 114 is provided on the corresponding first leg 111 for limiting the locking piece 223. The limiting groove 114 can more stably prevent the locking piece 223 from swinging, so that the extended pallet part 2 is reliably connected to the pallet carrier body 1, and the connection method between adjacent extended pallet parts 2 is the same as above.

[0040] In the specific embodiment of the present application, the boss 221 is provided with a positioning groove 2211 extending in the transverse direction. After the locking piece 223 is rotated to a corresponding angle, it can enter the positioning groove 2211 to be locked in position under the action of the first return spring 224. When the extended tray part 2 needs to be removed, the locking piece 223 is toggled to separate from the limiting groove 114 and then driven to rotate. After rotating to the right position, it can enter the positioning groove 2211 to be locked in position. At this time, the state of the locking piece 223 will not affect the disassembly and assembly process of the extended tray part 2.

[0041] In a specific embodiment of the present application, the pallet further includes at least one reinforcing leg 3 , and the reinforcing leg 3 is detachably installed in the fork channel 112 .

[0042] In a specific embodiment of the present application, the reinforced leg 3 includes a leg body 31 that is abutted against the bottom surface of the U-shaped frame 11, and at least two limit blocks 32 that can respectively abut against the corresponding square tubes are provided on the top surface of the leg body 31, and the second limit locking mechanism 33 arranged on the limit block 32 can act on the corresponding square tube to achieve locking of the reinforced leg 3.

[0043] Specifically, the limit blocks 32 provided on both sides can prevent the reinforcing legs 3 from moving or rotating randomly along the width direction of the pallet, so that the reinforcing legs 3 can be installed reliably.

[0044] In a specific embodiment of the present application, the second limiting locking mechanism 33 includes a locking rod 331 slidably arranged on the limiting block 32 and a second return spring 333 sleeved on the locking rod 331. The locking rod 331 can be automatically inserted into the limiting hole 115 located on the corresponding square tube under the action of the second return spring 333.

[0045] Specifically, one end of the locking rod 331 is provided with a shoulder 332 that abuts against one end of the second return spring 333, and the other end of the locking rod 331 is provided with an end stop 334 that prevents the locking rod 331 from separating from the limit stop block 32. The end stop portion 334 can be a nut, and the limit stop block 32 is made of channel steel. The concave cavity of the limit stop block 32 is used to accommodate the shoulder 332 and the second return spring 333. The limit hole 115 is formed by a sleeve welded on the corresponding square tube. The limit stop block 32 made of channel steel can also avoid mutual interference with the sleeve. When in use, the locking rod 331 is aligned with the corresponding limit hole 115 by moving the reinforcing leg 3 along the length direction, and the reinforcing leg 3 is made to have high strength.

[0046] The first position limiting locking mechanism 22 and the second position limiting locking mechanism 33 may also be bolts, and the bolts and corresponding holes or abutments realize the locking function.

[0047] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the embodiments of the present application may have various modifications and variations.
