Technical Field

[0001] The utility model relates to the technical field of material pallet handling vehicles, and particularly relates to a portable material transfer height adjustment device. Background Technique

[0002] A pallet truck, also known as a pallet jack or a pallet truck, is a manual portable device used for handling materials on pallets or transferring materials, such as the transfer of materials from a warehouse to a loading and unloading area. It is suitable for transferring materials over short distances and can enter narrow spaces;

[0003] As shown in the reference patent "A Pallet Truck" with the publication number "CN217708760U", a driving mechanism is used to drive the upward movement mechanism, and the movement of the lifting mechanism drives the upper body to rise and fall. Thus, the staff can use the lifting mechanism to lift the goods so that the goods are carried on the upper body, facilitating the transportation of the goods. During this process, the staff only needs to control the lifting mechanism to complete the loading and unloading of the goods, reducing the physical effort consumed by the staff when using the pallet truck;

[0004] However, when the existing pallet truck is used for loading, it is usually necessary to first laboriously move the material to the surface of the pallet to complete the loading, which causes great inconvenience when loading heavy materials.

[0005] Therefore, a portable material transfer height adjustment device is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a portable material transfer height adjustment device to solve the above problems, improving the problem that when the existing pallet truck is used for loading, it is usually necessary to first laboriously move the material to the surface of the pallet to complete the loading, which causes great inconvenience when loading heavy materials.

[0007] The utility model realizes the above purpose through the following technical solutions.

When the transfer vehicle is in use, the loading component can be used to move the nearby materials, so as to more conveniently move the materials above the transfer vehicle for convenient loading and transfer of the materials, making the material loading and transfer more convenient. The lifting component can be used to facilitate the movement of the movable frame to enable the movable frame to assist in loading materials at different heights;

[0008] The feeding component includes two movable plates slidably mounted on one side of the movable frame. The movable frame is U-shaped. On one side of each of the two movable plates, an inlet block is fixedly mounted. The inlet block is triangular in shape. On the surface of each movable plate, a plurality of hook plates are fixedly mounted. Each of the plurality of hook plates is in the shape of a hook. When feeding is required, the two movable plates can be synchronously controlled to slide out of the interior of the movable frame. Through the triangular shape of the inlet block, it is inserted under the material, and then the two movable plates are controlled to reset. When the movable plates reset, through the plurality of hook plates on the surface of the movable plates, the hook plates on the surface of the movable plates hook the material, so that when the movable plates are retracted into the interior of the movable plates, the material can be synchronously moved towards the movable frame, which is very convenient for assisting in feeding;

[0009] The feeding component further includes a first motor disposed on one side of the two movable plates. Both of the first motors are fixedly connected to the inner wall of the movable frame. A first screw rod is fixedly mounted at the output end of the first motor. One end of the first screw rod extends into the adjacent movable plate and is threadedly connected to the adjacent movable plate. When driving the movable plate to move, the first motor can be started to rotate the first screw rod to perform a threaded movement with the corresponding movable plate, thereby driving the movable plate to move out of and retract into the movable frame.

[0010] Preferably, a plurality of rollers are fixedly mounted on the inclined surface of the inlet block. The plurality of rollers are evenly distributed. When the inlet block contacts the material, it can conveniently guide the movement of the material through the inclined surface, and the friction between the material and the inlet block can be reduced through the plurality of rollers, thus making feeding more convenient.

[0011] Preferably, a guiding plate is fixedly mounted on one side of each of the plurality of hook plates. The top of each guiding plate is in the shape of an inclined surface. Through the inclined surfaces of the plurality of guiding plates, the movement of the material above the movable plate can be made more convenient, and when the movable plate is retracted and reset, the hook plate on the corresponding guiding plate side can better hook and move the material.

[0012] Preferably, the lifting component includes a second motor fixedly mounted on one side of the transfer vehicle. A second screw rod is fixedly mounted at the output end of the second motor. A support plate is fixedly mounted on one side of the transfer vehicle. The second screw rod and the support plate are externally sleeved with the same driving plate. One side of the driving plate is fixedly connected to the movable frame. The second screw rod is threadedly connected to the driving plate. When it is necessary to control the lifting of the movable frame, the second motor can be used to drive the second screw rod to rotate. The second screw rod performs a threaded movement with the driving plate, and the driving plate can synchronously drive the movable frame to move, so as to feed and transfer materials at different heights.

[0013] Preferably, two moving frames are slidably installed on one side of the driving plate. The two moving frames are respectively located on both sides of the support plate. Contact wheels are rotatably installed on the adjacent sides of the two moving frames. The contact wheels are in contact with the support plate. On the far sides of the two moving frames, two springs are fixedly installed respectively. The other ends of the two springs are fixedly connected to the driving plate. When the driving plate moves up and down, the driving plate slides outside the support plate. At this time, the rotation of the two contact wheels can reduce the friction when the driving plate moves. Moreover, the vibration generated when the driving plate moves can be buffered by the synchronous movement of the moving frame to squeeze the corresponding spring, thereby further reducing the damage caused to the support plate when the driving plate moves.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. When the transfer vehicle is in use, the feeding assembly can move the nearby materials, so as to more conveniently move the materials above the transfer vehicle for convenient feeding and transfer of the materials, making the feeding and transfer of the materials more convenient. The lifting assembly can facilitate the movement of the movable frame to enable the movable frame to assist in feeding materials at different heights.

[0016] 2. When it is necessary to control the lifting of the movable frame, the second motor can be started to make the driving plate drive the movable frame to move synchronously for feeding and transferring materials at different heights. When the driving plate moves up and down, the rotation of the two contact wheels can reduce the friction when the driving plate moves, and the buffer can also be carried out by the synchronous movement of the moving frame to squeeze the corresponding spring, thereby further reducing the damage caused to the support plate when the driving plate moves.

[0024] During specific implementation: As Figures 1-5 shown, a portable material transfer height adjustment device includes: a transfer vehicle 1, with a pull rod 2 hinged to one side of the transfer vehicle 1; a lifting and feeding mechanism 3, a telescopic lifting and feeding mechanism 3 for facilitating the feeding and transfer of materials is arranged on one side of the transfer vehicle 1; wherein, the lifting and feeding mechanism 3 includes a movable frame 31 arranged on one side of the transfer vehicle 1, a feeding assembly 32 is arranged on one side of the movable frame 31, the feeding assembly 32 includes two movable plates 321 slidably installed on one side of the movable frame 31, the movable frame 31 is arranged in a U shape, guiding blocks 322 are fixedly installed on one side of both movable plates 321, the guiding blocks 322 are arranged in a triangular shape, a plurality of hook plates 324 are fixedly installed on the surfaces of the movable plates 321, and all the hook plates 324 are arranged in a hook shape. The feeding assembly 32 further includes a first motor 326 arranged on one side of the two movable plates 321, both first motors 326 are fixedly connected to the inner wall of the movable frame 31, and a first screw rod 327 is fixedly installed at the output end of the first motor 326. One end of the first screw rod 327 extends into the adjacent movable plate 321 and is threadedly connected to the adjacent movable plate 321;

[0025] On one side of the transfer vehicle 1, a lifting component 33 is provided. When the transfer vehicle 1 is in use, the feeding component 32 can be used to move nearby materials, so as to more conveniently move the materials above the transfer vehicle 1 for convenient feeding and transfer of the materials, making the feeding and transfer of the materials more convenient. The lifting component 33 can be used to facilitate the movement of the movable frame 31, so that the movable frame 31 can assist in feeding materials at different heights. When feeding is required, the two movable plates 321 can be synchronously controlled to slide out of the interior of the movable frame 31. Through the triangular shape of the guiding block 322, it is inserted into the bottom of the material, and then the two movable plates 321 are controlled to reset. When the movable plates 321 are reset, through the multiple hook plates 324 on the surface of the movable plates 321, the hook plates 324 on the surface of the movable plates 321 hook the materials, so that when the movable plates 321 are retracted into the interior of the movable plates 321, the materials can be synchronously moved towards the movable frame 31 for convenient auxiliary feeding. When driving the movable plates 321 to move, the first motor 326 can be started to make the first motor 326 rotate the first screw rod 327 to perform a threaded movement with the corresponding movable plates 321, thereby driving the movable plates 321 to move out of and retract into the movable frame 31.

[0026] As Figure 2 , Figure 3 and Figure 5 shown, a plurality of rollers 323 are fixedly installed on the inclined surface of the guiding block 322, and the plurality of rollers 323 are evenly distributed. When the guiding block 322 contacts the material, the inclined surface can be used to conveniently guide the movement of the material, and the plurality of rollers 323 can reduce the friction force of the material when passing through the guiding block 322, thus making feeding more convenient. On one side of each of the plurality of hook plates 324, a guiding plate 325 is fixedly installed, and the tops of the guiding plates 325 are all inclined surfaces. Through the inclined surfaces of the plurality of guiding plates 325, it is more convenient for the material to move above the movable plate 321, and when the movable plate 321 is retracted and reset, the hook plates 324 on one side of the corresponding guiding plate 325 can better hook and move the material.

[0027] As Figure 2 , Figure 4 and Figure 5As shown, the lifting assembly 33 includes a second motor 331 fixedly installed on one side of the transfer vehicle 1. The output end of the second motor 331 is fixedly installed with a second screw rod 332. A support plate 334 is fixedly installed on one side of the transfer vehicle 1. The outer sides of the second screw rod 332 and the support plate 334 are penetrated and sleeved with the same driving plate 333. One side of the driving plate 333 is fixedly connected to the movable frame 31. The second screw rod 332 is threadedly connected to the driving plate 333. When it is necessary to control the lifting of the movable frame 31, the second motor 331 can be used to drive the second screw rod 332 to rotate.

Two moving frames 335 are slidably installed on one side of the driving plate 333. The two moving frames 335 are respectively located on both sides of the support plate 334. Contact wheels 336 are rotatably installed on the adjacent sides of the two moving frames 335. The contact wheels 336 are in contact with the support plate 334. Two springs 337 are fixedly installed on the opposite sides of the two moving frames 335. The other ends of the two springs 337 are fixedly connected to the driving plate 333. When the driving plate 333 moves up and down, the driving plate 333 slides on the outside of the support plate 334. At this time, the rotation of the two contact wheels 336 can be used to reduce the friction when the driving plate 333 moves. Moreover, the vibration generated when the driving plate 333 moves can be buffered by the synchronous movement of the moving frame 335 to squeeze the corresponding spring 337, thereby further reducing the damage caused to the support plate 334 when the driving plate 333 moves.

[0028] When the utility model is in use and feeding is required, two movable plates 321 can be synchronously controlled to slide out of the movable frame 31.

When driving the movable plates 321 to move, the first motor 326 can be started to rotate the first screw rod 327 to perform a threaded movement with the corresponding movable plates 321, so as to drive the movable plates 321 to move out of and retract into the movable frame 31. When the guiding block 322 contacts the material, the inclined surface can facilitate the guiding movement of the material, and a plurality of rollers 323 can reduce the friction of the material when passing through the guiding block 322, thus making feeding more convenient. Through the inclined surfaces of a plurality of guiding plates 325, the material can be moved more conveniently when moving above the movable plates 321, and when the movable plates 321 are retracted and reset, the hook plates 324 on one side of the corresponding guiding plates 325 can better hook and move the material. When it is necessary to control the lifting of the movable frame 31, the second motor 331 can be used to drive the second screw rod 332 to rotate, and the second screw rod 332 performs a threaded movement with the driving plate 333, so that the driving plate 333 can synchronously drive the movable frame 31 to move, thereby performing feeding transfer for materials at different heights. When the driving plate 333 moves up and down, the driving plate 333 slides outside the support plate 334. At this time, the rotation of two contact wheels 336 can reduce the friction when the driving plate 333 moves, and the vibration generated when the driving plate 333 moves can be buffered by the synchronous movement of the moving frame 335 to squeeze the corresponding spring 337, thereby further reducing the damage caused to the support plate 334 when the driving plate 333 moves.
