Description

Technical Field

[0001] This utility model relates to the field of pallet handling vehicle technology, and in particular to a pallet handling vehicle with lifting function. Background Technology

[0002] Pallet trucks are basic, efficient, and indispensable manual material handling equipment, designed for short-distance movement of goods loaded on standard pallets over flat, hard surfaces. Their core structure includes a robust, low-profile chassis with two forks at the front that insert into holes in the bottom of the pallet, and steering wheels and a hydraulic lifting system at the rear. This significantly saves manpower and improves efficiency, allowing individuals or small teams to easily move hundreds of kilograms or even tons of weight without complex mechanical assistance, while protecting the bottom of the goods from ground abrasion. They are a cornerstone tool for basic operations such as loading, unloading, transferring, and stacking palletized goods in modern logistics, warehousing, factories, supermarkets, and other locations. However, when using them, if the goods need to be moved to a higher position, workers need to lift the goods from the lower part of the truck to the higher position, which can be quite strenuous. Utility Model Content

[0003] In view of this, the present invention aims to provide a pallet transport vehicle with lifting function to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0004] The technical solution of this utility model embodiment is implemented as follows: it includes a support frame, two fork rods are fixedly installed at one end of the support frame, a fork base plate is fixedly connected to the bottom of the fork rods, a fork top plate is slidably connected above the fork rods, a scissor lift assembly is rotatably connected to one end of the fork base plate and the fork top plate, a lower slide and an upper slide are rotatably connected to both ends of the scissor lift assembly, one end of the lower slide is slidably connected to the top of the fork base plate, the upper slide is slidably connected to the bottom of the fork top plate, and an anti-fall baffle is slidably connected to the inner side of the fork top plate.

[0005] In some embodiments, the fork top plate has an internal mounting groove, a drive rack is slidably connected to the inside of the mounting groove, and one side of the drive rack is fixedly connected to the upper slide table.

[0006] In some embodiments, a drive gear set, an idler gear, and a transmission gear are rotatably connected inside the mounting slot. One end of the drive gear set meshes with the drive rack, and the other end of the drive gear set meshes with the idler gear.

[0007] In some embodiments, one end of the idler wheel is fixedly connected to a first synchronous pulley, and one end of the transmission gear is fixedly connected to a second synchronous pulley. The first synchronous pulley and the second synchronous pulley are connected by a first synchronous belt.

[0008] In some embodiments, a lifting gear plate is fixedly connected inside the anti-fall baffle, and a limit plate is fixedly connected below the anti-fall baffle, with the transmission gear and the lifting gear plate meshing with each other.

[0009] In some embodiments, a control component is fixedly connected above the support frame, and a roller assembly is fixedly connected to the bottom of the support frame and the fork arm.

[0012] The present invention has the following advantages due to the adoption of the above technical solution:

[0013] 1. A pallet handling vehicle with lifting function, wherein the lower slide slides along the fork base plate, driving the scissor lift assembly to deform and push the fork top plate to vertically lift the pallet. Through the mechanical lever principle, horizontal sliding is converted into vertical lifting force, eliminating the need for workers to manually lift heavy objects by bending over, significantly reducing the labor intensity of handling. Simultaneously, the upper slide drives the drive rack to move horizontally, thereby pushing the anti-fall baffle to extend obliquely. The baffle action is triggered synchronously during the lifting process, effectively preventing the pallet from sliding sideways and causing goods to fall.

[0014] 2. A pallet handling vehicle with lifting function, wherein the lifting motor drives the adjusting screws on both sides to rotate synchronously via a synchronous belt, thereby driving the adjusting nuts to push the drive bracket to move in parallel, ensuring that the deformation of the scissor fork frame components on both sides is consistent, thus ensuring the high stability of the pallet lifting process and avoiding the risk of tilting caused by uneven force on one side.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1:

[0028] like Figure 1-6As shown, a pallet truck with lifting function includes a support frame 1. Two fork rods 2 are fixedly installed at one end of the support frame 1. A fork base plate 5 is fixedly connected to the bottom of the fork rods 2. A fork top plate 6 is slidably connected above the fork rods 2. The support frame 1, fork rods, fork base plate 5, and fork top plate 6 are all made of high-strength metal. A scissor lift assembly 19 is rotatably connected to one end of the fork base plate 5 and the fork top plate 6. A lower slide 20 and an upper slide 21 are rotatably connected to both ends of the scissor lift assembly 19, respectively. One end of the lower slide 20 is slidably connected above the fork base plate 5, and the upper slide 21 is slidably connected to the bottom of the fork top plate 6. An anti-fall baffle 15 is slidably connected to the inner side of the fork top plate 6.

[0029] When in use, the lower slide 20 slides toward the support frame 1, thereby deforming the scissor lift assembly 19. This allows the upper slide 21, which is installed below the fork top plate 6, to slide, thereby moving the fork top plate 6 upward and pushing the pallet installed on the pallet truck upward. This way, when workers move goods, they do not need to bend over to lift heavy objects, which is more labor-saving.

[0030] Furthermore, when the fork top plate 6 moves upward, the anti-fall baffle 15 will rise simultaneously to prevent the pallet from slipping and damaging the goods when it moves upward.

[0031] In this embodiment, the fork top plate 6 has an installation groove 8 inside, and a drive rack 10 is slidably connected to the inside of the installation groove 8. One side of the drive rack 10 is fixedly connected to the upper slide table 21.

[0032] When the upper slide 21 slides toward the support frame 1, it can drive the drive rack 10 to move.

[0033] Inside the mounting slot 8, a drive gear set 9, an idler gear 11, and a transmission gear 14 are rotatably connected. One end of the drive gear set 9 meshes with the drive rack 10, and the other end of the drive gear set 9 meshes with the idler gear 11. One end of the idler gear 11 is fixedly connected to a synchronous pulley 12, and one end of the transmission gear 14 is fixedly connected to a synchronous pulley 13. The synchronous pulley 12 and the synchronous pulley 13 are connected by a synchronous belt 18.

[0034] The anti-fall baffle 15 has a lifting toothed plate 16 fixedly connected inside, and a limit plate 17 is fixedly connected below the anti-fall baffle 15. The transmission gear 14 and the lifting toothed plate 16 mesh with each other.

[0035] When the drive rack 10 moves, it will drive the drive gear set 9 to rotate. The drive gear set 9 consists of two identical gears mounted together on the same axis, which can drive the idler gear 11 meshing on the other side to rotate in the opposite direction.

[0036] Furthermore, the idler wheel 11 can drive the transmission gear 14 at the other end to rotate through the synchronous pulley 12, the synchronous pulley 13 and the synchronous belt 18. In this way, during the rotation of the transmission gear 14, the anti-fall baffle 15 can be pushed out obliquely upward. The raised anti-fall baffle 15 can prevent the pallet from slipping due to tilting during the lifting of the fork top plate 6.

[0037] In this embodiment, a control component 3 is fixedly connected above the support frame 1, and a roller assembly 4 is fixedly connected to the bottom of the support frame 1 and the fork lever 2. The control component 3 consists of components such as lever arm, handle, hydraulic cylinder and rocker arm, which can drive the lower roller assembly 4 to rise and lift. The control component 3 is the existing technology.

[0038] In this embodiment: When in use, the lower slide 20 is slid towards the support frame 1, thereby causing the scissor lift assembly 19 to deform. This allows the upper slide 21, which is installed below the fork top plate 6, to slide, thereby causing the fork top plate 6 to move upward and push the pallet installed on the pallet truck upward. This way, when workers move goods, they do not need to bend over to lift heavy objects, which is more labor-saving.

[0039] Furthermore, when the fork top plate 6 moves upward, the anti-fall baffle 15 will rise simultaneously to prevent the pallet from slipping and damaging the goods when it moves upward.

[0040] When the upper slide 21 slides toward the support frame 1, it can drive the drive rack 10 to move; and when the drive rack 10 moves, it will drive the drive gear set 9 to rotate. The drive gear set 9 consists of two identical gears coaxially mounted together, which can drive the idler wheel 11 meshing on the other side to rotate in the opposite direction.

[0041] Furthermore, the idler wheel 11 can drive the transmission gear 14 at the other end to rotate through the synchronous pulley 12, the synchronous pulley 2 13 and the synchronous belt 18. In this way, during the rotation of the transmission gear 14, the anti-fall baffle 15 can be pushed out obliquely upward. The raised anti-fall baffle 15 can prevent the pallet from slipping due to tilting during the lifting of the fork top plate 6.

[0042] The control component 3 consists of components such as a lever arm, a handle, a hydraulic cylinder, and a rocker arm, which can drive the lower roller assembly 4 to rise and lift. The control component 3 is currently the existing technology.

[0043] Example 2:

[0044] A pallet transporter with lifting function is provided in this embodiment, which is improved based on embodiment 1 as follows: Figure 1-6 As shown,

[0045] In this embodiment, drive brackets 7 are fixedly connected to both sides of the lower slide 20, and the other end of the drive bracket 7 is slidably connected to the fork rod 2. An adjusting nut 23 is fixedly connected to one side of the drive bracket 7. An adjusting screw 24 is rotatably connected to one end of the support frame 1 and the fork rod 2. One end of the adjusting screw 24 is threaded to the adjusting nut 23, and the other end of the adjusting screw 24 is fixedly connected to a synchronous pulley 25. The multiple synchronous pulleys 25 are connected to each other by a synchronous belt 26. A lifting motor 22 is fixedly connected inside the support frame 1, and the power output end of the lifting motor 22 is fixedly connected to one side of the synchronous pulley 25.

[0046] When the lifting motor 22 is working, the adjusting screws 24 on both sides can be rotated simultaneously by the synchronous pulley 3 25 and the synchronous belt 26. Then, the driving brackets 7 on both sides can be moved backward by the adjusting nut 23, which simultaneously drives the lower slide 20 in front to slide, so that the scissor lift assemblies 19 on both sides can deform at the same time, thereby making the pallet rise and fall stably.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
