Description

Technical Field

[0001] This utility model belongs to the field of handling vehicle technology, specifically relating to an electric handling vehicle that is easy to assemble and disassemble. Background Technology

[0002] Forklifts are common handling tools used frequently in daily life. When in use, the forks are inserted into the pallet holes, and a hydraulic lifting system is driven to lift and lower the palletized goods, with the drive unit completing the handling operation. Existing patent CN221397197U discloses a walk-behind single-fork manual pallet truck, including: a handle, a frame, a hydraulic lifting system located at the bottom of the handle, and a linkage mechanism. It also includes: auxiliary wheels, respectively located on both sides of the hydraulic lifting system support. The frame includes: a drive wheel located below the support, a front plate connected to the linkage mechanism, a top plate located at the upper part of the front plate, a single fork, and a self-supporting device located below the fork. Existing pallet trucks are large in size, and the handle and hydraulic lifting system are often not detachable, resulting in a large overall structure that is inconvenient for transportation and transfer. Furthermore, existing pallet trucks rely on manual lifting and pushing, resulting in a low level of automation. Therefore, there is a need to design an easily detachable electric pallet truck to overcome these difficulties. Summary of the Invention

[0003] This utility model addresses the problems existing in the prior art by designing an electric transport vehicle that is easy to assemble and disassemble. The lifting component, rotating component and handle component of this utility model can be disassembled from each other, and the packaged size is small, making it easy to store and transport.

[0005] Preferably, the main support is provided with a rotatable adapter, a drive assembly is fixedly connected to the adapter below it, and a lifting assembly is fixedly connected to the adapter above it.

[0006] Preferably, the drive assembly includes a motor bracket, a motor body, and a roller body; the motor bracket is fixedly connected to the adapter, and the motor bracket is provided with a roller body that is rotatably connected to it; the motor body is fixedly installed on the motor bracket, and when the motor body is working, it drives the roller body to rotate relative to the motor bracket.

[0007] Preferably, the main support is provided with a pair of caster wheel assemblies on both sides, and the caster wheel assemblies are rotatably connected to the main support; the two caster wheel assemblies are arranged on both sides of the drive assembly.

[0008] By setting up an adapter, both the drive assembly and the lifting assembly can rotate relative to the main support. When the motor is working, it drives the roller assembly to rotate. The linkage roller assembly is a commonly used component in existing forklifts and will not be discussed in detail here. Thus, the roller assembly and the linkage roller assembly can drive the pallet truck, resulting in a high degree of automation. By setting up a caster wheel assembly, the stability of the pallet truck is increased, preventing it from swaying left and right under light load.

[0009] Preferably, the lifting assembly includes a hydraulic assembly with a lifting rod inside, which extends and retracts when the hydraulic assembly is working. The hydraulic assembly has a mounting groove on its side, and a rotating assembly is located within the mounting groove. The rotating assembly includes a rotating mounting base, a connecting cover plate, a spindle, a backing body, and a pair of supporting bushings. The rotating mounting base is rotatably connected to the mounting groove, and the spindle is mounted on the rotating mounting base. Supporting bushings are fitted over the outer layer of the spindle, and a locating pin is provided between the supporting bushings and the spindle to fix them together. The backing body is fitted over the outer layer of the spindle and is located between the two supporting bushings. A telescopic rod that can extend and retract relative to the mounting groove is provided within the mounting groove, and the telescopic rod is fitted into the backing body.

[0010] Preferably, the support bushing is provided with a limiting step, and when the support bushing is installed on the rotary mounting base, the limiting step is fitted with the inner wall of the rotary mounting base; an open retaining ring is provided between the spindle and the abutment body, and the abutment body is in the shape of a hollow cylinder; the outer contour of the abutment body and the outer contour of the open retaining ring are adapted to each other, and the axial length of the abutment body is greater than the axial length of the open retaining ring; a connecting shaft is provided between the rotary mounting base and the mounting groove to connect the two.

[0011] Preferably, a hollow guide shaft is provided perpendicularly to the mounting groove, and the telescopic rod is slidably installed inside the hollow guide shaft; a limiting cover is fixedly connected to the telescopic rod, and a compression spring is provided between the limiting cover and the bottom of the mounting groove; one end of the compression spring is installed on the limiting cover, and the other end of the compression spring abuts against the bottom of the mounting groove; the compression spring is sleeved on the outer layer of the hollow guide shaft; a limiting pin is fixedly connected to the mounting groove, and a connecting cover plate is detachably connected to the rotating mounting base, with a limiting plate fixedly connected to the bottom of the connecting cover plate; in the default state, the telescopic rod is in the extended state, and the bottom of the limiting plate abuts against the limiting pin.

[0013] Preferably, the connecting cover is mounted on the rotary mounting base by screws; a handle assembly is provided between the connecting cover and the rotary mounting base, and the handle assembly is mounted on the rotary mounting base by screws.

[0014] By incorporating a support bushing and locating pin, the mandrel is easily installed into the rotary mounting base. A limiting step on the support bushing prevents axial movement of the mandrel relative to the rotary mounting base. An open retaining ring securely mounts the abutment body to the outer layer of the mandrel, preventing unauthorized movement and ensuring constant contact between the abutment body and the telescopic rod. In the default state, the compression spring is compressed, keeping the telescopic rod abutting against the abutment body. This keeps the rotary mounting base upright, facilitating easier gripping of the handle assembly. Users can easily grasp the handle assembly without bending over. A limiting pin within the mounting groove limits the initial position of the rotary mounting base. A buffer prevents significant impact on the lifting assembly when the rotary mounting base automatically resets after use. The handle assembly is positioned between the rotary mounting base and the connecting cover, ensuring a more stable and reliable connection. Furthermore, the rotary mounting base, mounting groove, and handle assembly are all detachable, reducing initial packaging size and facilitating storage and transportation.

[0015] Compared with the prior art, the present invention has the following advantages: 1. The present invention can control the movement of the transport vehicle through the drive component and can control the lifting of the transport vehicle through the lifting component, with a high degree of automation; 2.

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figures 1 to 5 As shown, this embodiment discloses an electric pallet truck that is easy to assemble and disassemble, including a main frame 1, a base plate 2 fixedly mounted on the main frame 1, and a connecting rod roller assembly 3 between the base plate 2 and the main frame 1; a main support 4 is provided on the rear side of the main frame 1, and a drive assembly 5 is provided below the main support 4 and rotatably connected thereto; a lifting assembly 6 is provided above the main support 4 and rotatably connected thereto, the lifting assembly 6 including a lifting rod 61, the lifting rod 61 being rotatably connected to the main frame 1; the lifting assembly 6 also includes a mounting groove 62, in which a rotating assembly 7 is rotatably connected thereto; a telescopic rod 8 that can move relative to it is provided in the mounting groove 62, the telescopic rod 8 being arranged adjacent to the rotating assembly 7; and a handle assembly 9 detachably connected thereto is provided on the rotating assembly 7.

[0018] The main support 4 has an adapter seat 10 rotatably connected to it. Below the adapter seat 10 is a drive assembly 5 fixedly connected to it, and above the adapter seat 10 is a lifting assembly 6 fixedly connected to it. The drive assembly 5 includes a motor bracket 51, a motor body 52, and a roller body 53. The motor bracket 51 is fixedly connected to the adapter seat 10, and the roller body 53 is rotatably connected to it. The motor body 52 is fixedly mounted on the motor bracket 51, and when the motor body 52 is working, it drives the roller body 53 to rotate relative to the motor bracket 51. Pairs of universal wheel assemblies 11 are provided on both sides of the main support 4, and the universal wheel assemblies 11 are rotatably connected to the main support 4. The two universal wheel assemblies 11 are located on both sides of the drive assembly 5.

[0019] The lifting assembly 6 includes a hydraulic assembly 63, within which a lifting rod 61 is provided. When the hydraulic assembly 63 is working, it drives the lifting rod 61 to extend and retract. The side of the hydraulic assembly 63 has a mounting groove 62, within which a rotating assembly 7 is provided. The rotating assembly 7 includes a rotating mounting base 71, a connecting cover plate 72, a spindle 73, abutment body 74, and a pair of support bushings 75. The rotating mounting base 71 is rotatably connected to the mounting groove 62, and the spindle 73 is mounted on the rotating mounting base 71. Support bushings 75 are fitted over the outer layer of the spindle 73, and a positioning pin 76 is provided between the support bushings 75 and the spindle 73 to fix them together. The abutment body 74 is fitted over the outer layer of the spindle 73 and is positioned between the two support bushings 75. A telescopic rod 8, which can extend and retract relative to the mounting groove 62, is provided within the mounting groove 62, and the telescopic rod 8 is fitted against the abutment body 74. The support bushing 75 is provided with a limiting step 77. When the support bushing 75 is installed on the rotary mounting base 71, the limiting step 77 is fitted with the inner wall of the rotary mounting base 71. An open retaining ring 78 is provided between the spindle 73 and the abutment body 74. The abutment body 74 is a hollow cylinder. The outer contour of the abutment body 74 is adapted to the outer contour of the open retaining ring 78. The axial length of the abutment body 74 is greater than the axial length of the open retaining ring 78. A connecting shaft 79 is provided between the rotary mounting base 71 and the mounting groove 62 to connect the two. A hollow guide shaft 12 is provided perpendicularly within the mounting groove 62, and the telescopic rod 8 is slidably mounted within the hollow guide shaft 12. A limiting cover 13 is fixedly connected to the telescopic rod 8, and a compression spring 14 is provided between the limiting cover 13 and the bottom of the mounting groove 62. One end of the compression spring 14 is mounted on the limiting cover 13, and the other end abuts against the bottom of the mounting groove 62. The compression spring 14 is sleeved on the outer layer of the hollow guide shaft 12. A limiting pin 15 is fixedly connected to the mounting groove 62, and a connecting cover 72 is detachably connected to the rotating mounting base 71. A limiting plate 16 is fixedly connected to the bottom of the connecting cover 72. In the default state, the telescopic rod 8 is in the extended state, and the bottom of the limiting plate 16 abuts against the limiting pin 15. A buffer 17 is fixedly mounted on the limiting plate 16, and the buffer 17 is positioned facing the side wall of the mounting groove 62. The connecting cover plate 72 is mounted on the rotating mounting base 71 by screws; a handle assembly 9 is provided between the connecting cover plate 72 and the rotating mounting base 71, and the handle assembly 9 is mounted on the rotating mounting base 71 by screws.

[0020] The specific operation process of this embodiment is as follows: By setting the adapter 10, both the drive assembly 5 and the lifting assembly 6 can rotate relative to the main support 4. When the motor body 51 is working, it drives the roller body 52 to rotate. The connecting rod roller assembly 3 is a commonly used component in existing forklifts and will not be discussed in detail here. Then, the roller body 52 and the connecting rod roller assembly 3 can drive the pallet truck to move, with a high degree of automation. By setting the universal wheel assembly 11, the stability of the pallet truck is increased, preventing the pallet truck from swaying left and right under light load.

[0021] By setting up a support bushing 75 and a positioning pin 76, the spindle 73 is easily installed into the rotary mounting base 71. Since the support bushing 75 has a limiting step 77, axial movement of the spindle 73 relative to the rotary mounting base 71 is prevented. By setting an open retaining ring 78, the abutment body 74 is stably installed on the outer layer of the spindle 73, preventing the abutment body 74 from moving freely and ensuring that the abutment body 74 is always in contact with the telescopic rod 8. In the default state, the compression spring 14 is in a compressed state, so the telescopic rod 8 always abuts against the abutment body 74. This keeps the rotary mounting base 71 in an upright position, making it easier for the user to grip the handle assembly 9. The user can easily grip the handle assembly 9 without bending over. Since a limiting pin 15 is provided in the mounting groove 62, the initial position of the rotary mounting base 71 is limited. By setting a buffer 17, when the rotary mounting base 71 automatically resets after use, it prevents the rotary mounting base 71 from having a large impact on the lifting assembly 6. Because the handle assembly 9 is positioned between the rotating mounting base 71 and the connecting cover plate 72, the connection between the handle assembly 9 and the rotating assembly 7 is more stable and reliable. At the same time, the rotating mounting base 71, the mounting groove 62, and the handle assembly 9 are all detachable from each other, thus reducing the initial packaging size and facilitating storage and transportation.
