[0007] As a further solution of the present invention, a partition is fixed in the middle of the lifting frame, the support assembly passes through the partition and is installed on both sides of the lifting frame, two sliding grooves are opened at the bottom of one side of the lifting frame, and the support assembly is slidably connected in the two sliding grooves.
[0008] As a further solution of the present invention, the supporting assembly includes a screw rod, the threads on both sides of the screw rod are in opposite directions, the two ends of the screw rod are installed in the lifting frame through bushings, the two sides of the screw rod are threadedly connected with threaded caps, a fork is fixed outside the threaded cap, the fork is L-shaped, and the two ends of the screw rod are respectively fixedly connected with a turning handle.
[0009] As a further solution of the present invention, the bottom support assembly includes two support plates, which slide through the sliding holes. The support plates are L-shaped, and a support wheel is installed on one side of the bottom of the support plate. A push rod is fixedly connected between the two support plates. A through hole is opened on the side wall of the support plate, and the locking assembly is installed in the through hole.
[0010] As a further solution of the present invention, the locking assembly includes a card plate, which is arranged in the through hole. The side of the card plate close to the counterweight base is designed in a barb shape and is clamped in the slot. Two sliding rods slide through the card plate, and the sliding rods are fixed in the through hole. A spring is connected to the outer sleeve of the sliding rod, and the two ends of the spring are respectively fixed to the inner wall of the through hole and the bottom of the card plate, and a pull rod is fixedly connected between the two card plates.
[0011] As a further solution of the present invention, walking wheels are respectively installed on both sides of the bottom of the counterweight base, and a handle is fixedly connected to the side of the fixing frame away from the lifting assembly.
[0012] A method for using a lifting device for transporting automobile parts, the method comprising the following steps: When transporting auto parts, the driving motor is controlled to drive the stud to rotate. During the rotation of the stud, the nut can drive the lifting frame to move downward, so that the lifting frame drives the two forks to move downward. When the forks are close to the ground, the driving motor stops working, and the fixed frame is pushed by the handle, so that the fixed frame drives the walking wheels at the bottom of the counterweight base to roll on the ground. When the counterweight base drives the two pallets to move to the position of the parts, the parts are located between the two pallets, and the two forks are inserted into the bottom of the parts. The handle is continued to be pushed to make the parts contact with the inner side of the forks. Secondly, the driving motor is controlled to drive the stud to rotate in the opposite direction, and the nut drives the lifting frame to move upward in the fixed frame. The lifting frame drives the parts to move upward through two forks. When the parts are lifted to the top of the trailer of the transfer vehicle, the fixed frame is pushed by the handle so that the fixed frame drives the fork to move through the lifting frame, and the fork delivers the parts to the inside of the trailer of the transfer vehicle. When putting down the parts, the driving motor is controlled to drive the stud to rotate forward, so that the fork moves down and can put down the parts. Secondly, the bottom of the fork contacts the trailer of the transfer vehicle. When the driving motor continues to work, the fork is at a high place and supported by the trailer, so that it can support the counterweight base and the driving motor. At this time, the two pallets are below the trailer of the transfer vehicle, causing interference with the rise of the counterweight base. By holding the pull rod and pressing it down, the pull rod drives the two pallets to move downward, so that the pallet can move down in the card slot in the counterweight base, so that it is out of the locked state with the card slot, and the card plate is limited by the sliding rod inside the through hole to ensure the stability of the pallet moving up and down. Secondly, the pull rod is pulled outward, so that the pull rod drives the two pallets to slide in the sliding hole through the card plate until the end of the pallet moves into the sliding hole. At this time, the pallets under the two forks are removed. As the counterweight base drives the two pallets to move up, when the pallet is higher than the trailer of the transfer vehicle, the two pallets are driven to move in the sliding hole by the push rod, and the pallet is moved again to the bottom of the fork. During the movement of the pallet, the pallet is driven to be stuck in the card slot. After the card plate with a hook-shaped design is embedded in the card slot, the card plate is supported by the elastic force of the spring, so that the card plate can be buckled on the top of the inner wall of the card slot to achieve the purpose of locking the pallet. At this time, the entire lifting device is transferred to the trailer of the transfer vehicle; When the positions of the two forks need to be adjusted, the screw rod is driven to rotate by the turning handle. Since the threads on both sides of the screw rod are in opposite directions, the two threaded caps respectively drive the two forks to move away from or closer to each other, and the forks drive the slider to slide in the slide slot, thereby improving the stability of the horizontal movement of the forks. Therefore, by adjusting the distance between the two forks, it is convenient to carry and lift automobile parts of different specifications.
[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention lifts the parts to the top of the trailer of the transfer vehicle, pushes the fixing frame through the handle, so that the fixing frame drives the fork to move through the lifting frame, and the fork delivers the parts to the inside of the trailer of the transfer vehicle. When putting down the parts, the drive motor is controlled to drive the stud to rotate forward, so that the fork moves down and can put down the parts. Secondly, the bottom of the fork contacts the trailer of the transfer vehicle. When the drive motor continues to work, the fork is at a high place and supported by the trailer, so that it can support the counterweight base and the drive motor. The pull rod is held and pressed down, and the pull rod drives the two pallets to move downward, so that the pallets It can move down in the slot in the counterweight base to disengage it from the locked state with the slot, and then pull the pull rod outward to drive the two pallets to slide in the sliding hole through the card plate until the end of the pallet moves into the sliding hole. At this time, the pallets under the two forks are removed. When the pallet is higher than the trailer of the transfer vehicle, the two pallets are driven to move in the sliding hole by the push rod, and the pallet is moved back to the bottom of the fork. The fixed frame can be pushed to transfer the entire lifting device to the trailer of the transfer vehicle. Therefore, it only needs to assist in adjusting the position of the bottom support assembly to achieve the purpose of automatic climbing of the device and improve the convenience of operation.
[0014] 2. The present invention drives two pallets to move in the sliding hole through a push rod, and moves the pallets again to the bottom of the fork. During the movement of the pallet, the pallet is driven to be stuck in the slot. After the barbed-hook-shaped pallet is embedded in the slot, the pallet is supported by the elastic force of the spring, so that the pallet can be buckled on the top of the inner wall of the slot, thereby achieving the purpose of locking the pallet and improving the stability of the device supported by the pallet and the support wheel. When the position of the fork needs to be adjusted, the screw rod is driven to rotate by the turning handle. Since the threads on both sides of the screw rod are in opposite directions, the two threaded caps respectively drive the two forks away from or close to each other, and the fork drives the slider to slide in the slide slot, thereby improving the stability of the horizontal movement of the fork. Therefore, the spacing between the two forks is adjusted to facilitate the handling and lifting of automobile parts of different specifications, so that the lifting device has wide versatility.

At this time, the two support plates (801) are below the trailer of the transfer vehicle, causing interference with the rise of the counterweight base (1); By holding the pull rod (10) and pressing it downward, the pull rod (10) drives the two pallets (901) to move downward, so that the pallet (901) can move downward in the slot (11) in the counterweight base (1), so that it is out of the locked state with the slot (11), and the pallet (901) is limited by the slide bar (902) inside the through hole (804) to ensure the stability of the pallet (901) moving up and down. Then, the pull rod (10) is pulled outward, so that the pull rod (10) drives the two pallets (801) to slide in the slide hole (7) through the pallet (901) until the end of the pallet (801) moves into the slide hole (7). At this time, the pallet (801) under the two forks (404) is removed. The counterweight base (1) drives the two pallets (801) to move upward. When the pallets (801) are higher than the trailer of the transfer vehicle, the push rod (803) drives the two pallets (801) to move in the slide hole (7) to move the pallets (801) back to the bottom of the fork (404). During the movement of the pallets (801), the card plate (901) is driven to be inserted into the card slot (11). After the card plate (901) with a barbed hook design is embedded in the card slot (11), the elastic force of the spring (903) supports the card plate (901), so that the card plate (901) can be buckled on the top of the inner wall of the card slot (11), thereby achieving the purpose of locking the pallet (801). At this time, the entire lifting device is transferred to the trailer of the transfer vehicle; When the positions of the two forks (404) need to be adjusted, the screw rod (401) is driven to rotate by the rotating handle (402). Since the threads on the two sides of the screw rod (401) are in opposite directions, the two threaded caps (403) respectively drive the two forks (404) to move away from or towards each other, and the forks (404) drive the slider (405) to slide in the slide groove (304), thereby improving the stability of the horizontal movement of the forks (404). Therefore, by adjusting the distance between the two forks (404), it is convenient to carry and lift automobile parts of different specifications.
