[0004] The lifting frame solves the problem that the lifting frame is easily damaged due to long-term uneven force during maintenance, causing the car to fall, which greatly endangers the life safety of maintenance personnel. However, the application range of the lifting frame is small, and it cannot adjust itself according to the size of different cars. Utility Model Content

[0005] The purpose of the present application is to provide a lifting device for automobile maintenance in order to solve the above-mentioned technical problems. The lifting device can adjust itself according to the sizes of different automobiles so that the device body is suitable for installing automobiles of various sizes and has a wide range of applications.

[0006] The present application provides a lifting device for automobile maintenance, comprising a device body, wherein the device body comprises:

[0007] A distance adjustment mechanism, comprising a motor, an electric telescopic worm and a worm gear;

[0008] Wheel fixing mechanism;

[0009] Scissor telescopic frame;

[0010] A base, which cooperates with the scissor-type telescopic frame;

[0011] Among them, the motor is connected to the electric telescopic worm, the worm wheel is matched with the electric telescopic worm, the distance adjustment mechanism is placed on the base, the distance adjustment mechanism is connected to the scissors-type telescopic frame, and the wheel fixing mechanism is connected to the scissors-type telescopic frame.

[0012] In the technical scheme, by arranging a distance adjustment mechanism and a wheel fixing mechanism in the device body, scissor-type telescopic frames are arranged at the four corners of the base, and a motor, an electric telescopic worm and a worm wheel are arranged in the distance adjustment mechanism, the motor and the electric telescopic worm are connected, the worm wheel and the electric telescopic worm are matched, and the base and the scissor-type telescopic frame are matched. When the staff needs to adjust the wheel-wise spacing of the scissor-type telescopic frame, the electric telescopic worm is controlled to be extended and retracted, so that the wheel-wise spacing of the scissor-type telescopic frame can be adjusted. When the staff needs to adjust the axial spacing of the scissor-type telescopic frame, the motor is controlled to rotate, and the rotation of the motor drives the electric telescopic worm to rotate, and the worm wheel is connected to the electric telescopic worm. Through the cooperation between it and the electric telescopic worm, the worm wheel and the electric telescopic worm rotate together, so that the staff can adjust the axial spacing of the scissors-type telescopic frames through the linkage relationship, so that the device body can adjust the wheel spacing and the axial spacing according to the specific size of the car. The application range is wide. After adjusting the wheel spacing and the axial spacing, the four tires of the car are respectively fixed to the wheel fixing mechanisms at the four corners of the base, and the wheel mechanism is connected to the scissors-type telescopic frames. When the staff needs to repair the bottom of the car, the height of the two scissors-type telescopic frames at the front wheels or the two scissors-type telescopic frames at the rear wheels can be adjusted separately to facilitate maintenance by the staff, and it is very practical.

[0013] Furthermore, the distance adjustment mechanism includes:

[0014] A first gear connected to the worm gear;

[0015] a second gear meshing with the first gear;

[0016] A first screw rod, which cooperates with the first gear;

[0017] A second screw rod, which cooperates with the second gear;

[0018] Wherein, the first screw rod is connected to the scissor-type telescopic frame at one end, and the second screw rod is connected to the scissor-type telescopic frame at the other end.

[0019] In the present technical solution, a first gear, a second gear, a first screw rod and a second screw rod are arranged in the distance adjustment mechanism, the first gear is connected to the worm gear, the second gear is meshed with the first gear, the first screw rod is matched with the first gear, and the second screw rod is matched with the second gear. When the motor rotates, the first gear and the second gear rotate synchronously with the worm gear, and drive the first screw rod and the second screw rod to slide on the corresponding first gear and second gear. Since the first screw rod is connected to the scissors telescopic frame at one end, and the second screw rod is connected to the scissors telescopic frame at the other end, the staff can adjust the axial spacing of the scissors telescopic frame only by rotating the motor, which is more convenient to use.

[0020] Furthermore, the wheel fixing mechanism comprises:

[0021] load-bearing plates;

[0022] A limiting plate, which is rotatably connected to the load-bearing plate;

[0023] A first hydraulic cylinder, one end of which is connected to the load-bearing plate, and the other end of which is connected to the limit plate;

[0024] Wherein, the cross section of the limiting plate is in an arc shape.

[0025] In the present technical solution, a load-bearing plate and a limit plate are arranged in the wheel fixing mechanism. The load-bearing plate facilitates the wheel fixing mechanism to stably support the automobile. The cross-section of the limit plate is arc-shaped, which facilitates the limit plate to cover the automobile wheel. One end of the first hydraulic cylinder is connected to the load-bearing plate, and the other end is connected to the limit plate. When the automobile wheel needs to be fixed, the staff controls the extension of the first hydraulic cylinder to form a certain angle between the limit plate and the load-bearing plate. The limit plate and the load-bearing plate can cover the wheel after cooperating with each other, so that the automobile wheel can be stably fixed on the wheel fixing mechanism, thereby improving the safety of the device body.

[0026] Furthermore, the base comprises:

[0027] Mobile components;

[0028] An auxiliary vehicle transport plate, which is rotatably connected to the base;

[0029] Support plate including non-slip pads.

[0030] In the present technical solution, a moving component and an auxiliary vehicle transport plate are arranged on the base, and the auxiliary vehicle transport plate is rotatably connected to the base. When the car is to be transported to the device body, the user rotates the auxiliary vehicle transport plate to facilitate the car to move along the auxiliary vehicle transport plate to the device body. The support plate and the anti-skid pad are in contact with the ground. The support plate enables the device body to stably support the car, and the anti-skid pad can effectively increase the friction between the device body and the ground, making it convenient for the staff to stably repair the car on the device body. The moving component makes it convenient for the staff to carry the device body and is convenient for the staff to use.

[0031] Furthermore, the mobile component includes:

[0032] A pull rod, which is rotatably connected to the base;

[0033] The second hydraulic cylinder;

[0034] The rotating wheel is rotatably connected to the second hydraulic cylinder.

[0035] In the present technical solution, a pull rod is provided in the moving assembly, and the pull rod is rotatably connected to the base, which greatly facilitates the staff to carry the device body. The rotating wheel is rotatably connected to the second hydraulic cylinder. When the device body needs to be carried, the staff extends the second hydraulic cylinder to make the rotating wheel contact with the ground, which makes it convenient for users to carry the device body. When the device body needs to be worked, the staff shortens the second hydraulic cylinder to make the anti-slip pad contact with the ground, which makes it convenient for users to repair the car through the device body.

[0036] Furthermore, the device body is also provided with an anti-slip support plate;

[0037] Wherein, the anti-skid support plate includes a third hydraulic cylinder, and the third hydraulic cylinder is placed between the scissor-type telescopic frames at both ends.

[0038] In the present technical solution, an anti-skid support plate is provided in the device body, and the anti-skid support plate is connected to the base through a third hydraulic cylinder. After the staff fixes the car through the wheel fixing mechanism, they adjust the height of the scissor telescopic frames on both sides to repair the bottom of the car. At this time, the car cannot be stably fixed, and the staff further fixes the middle position of the car by adjusting the height of the third hydraulic cylinder to prevent the car from falling and prevent the lives of the staff from being threatened.

[0039] The beneficial effects of this application are:

[0040] 1. The staff adjusts the wheel spacing of the scissor telescopic frames by controlling the electric telescopic worm, and the staff adjusts the axial spacing of the scissor telescopic frames by controlling the rotation of the motor, so that the device body can adjust the wheel spacing and axial spacing according to the specific size of the car. It has a wide range of applications. When the bottom of the car needs to be repaired, the staff can separately adjust the height of the two scissor telescopic frames at the front wheels or the two scissor telescopic frames at the rear wheels to facilitate maintenance, and it is more practical.

[0041] 2. When the motor rotates, the first gear and the second gear rotate synchronously with the worm gear, and drive the first screw rod and the second screw rod to slide on the corresponding first gear and second gear. Since the first screw rod is connected to the scissors-type telescopic frame at one end, and the second screw rod is connected to the scissors-type telescopic frame at the other end, the staff can adjust the axial spacing of the scissors-type telescopic frame only by rotating the motor, which is convenient to use.

[0042] 3. The load-bearing plate facilitates the wheel fixing mechanism to stably support the car, and the limit plate with an arc-shaped cross-section facilitates covering the car wheel. One end of the first hydraulic cylinder is connected to the load-bearing plate, and the other end is connected to the limit plate. When the car wheel needs to be fixed, the first hydraulic cylinder is controlled to extend so that the limit plate and the load-bearing plate cooperate with each other to cover the wheel, thereby fixing the wheel and improving the safety of the device body.
