Description

Technical Field

[0001] This utility model relates to the technical field of lifting devices for automobile inspection, and in particular to a lifting frame for automobile inspection. Background Technology

[0002] With the continuous development of the automotive inspection industry and the sustained growth of car ownership, inspection needs are becoming increasingly diversified and sophisticated. As a key piece of equipment in the automotive repair and inspection process, the performance of automotive inspection lifting frames directly affects the efficiency and quality of inspection work. They bear the important task of lifting cars to a suitable height so that repair personnel can conduct comprehensive inspections and repairs on the vehicle's undercarriage, chassis, and other parts. With the continuous advancement of automotive technology, the weight, size, and structure of cars are becoming increasingly complex, placing higher and higher demands on the functions and performance of lifting frames. They not only need to have reliable lifting capabilities but also excellent performance in terms of stability and safety.

[0003] Traditional vehicle inspection lifts typically use simple hydraulic or electric drive systems to achieve their lifting function. Generally, a motor drives a lead screw to rotate, causing the lifting platform to rise or fall. Fixed supports are used to support the weight of the lifting platform and the vehicle. The working principle of this type of lift is mainly based on basic mechanical transmission and gravity support. By controlling the forward and reverse rotation of the motor, the rotation direction of the lead screw is adjusted, thereby changing the height of the lifting platform. During the inspection process, the repair personnel drive the vehicle onto the lift, activate the lifting device to raise the vehicle to the appropriate height, and then perform the inspection operation.

[0004] However, this traditional vehicle inspection lift has its drawbacks. When faced with inspection tasks involving heavier vehicles or when working on uneven ground, the lack of additional support components and reliance solely on fixed supports makes the overall structure of the lift prone to imbalance and swaying. This can severely affect the accuracy of the data obtained during the inspection process, making it difficult to accurately diagnose vehicle faults. It also increases safety risks, as the vehicle may slip off the lift, potentially causing an accident that threatens the lives of repair personnel and the integrity of the vehicle. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lifting frame for vehicle inspection, which aims to improve the problem that the lack of additional support can easily lead to overall structural imbalance and swaying when operating on heavier vehicles or uneven ground, affecting the inspection accuracy and potentially causing the vehicle to slip off the lifting frame and cause a safety accident.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lifting frame for automobile inspection, comprising a device body, a support frame fixedly connected to the outer wall of the device body, a motor fixedly connected to the upper surface of the support frame, a bidirectional threaded rod fixedly connected to the output end of the motor, a lifting platform threadedly connected to the outer wall of the bidirectional threaded rod, a guide column slidably connected to the inner wall of the lifting platform, a sliding column fixedly connected to the upper surface of the lifting platform, a support platform slidably connected to the outer wall of the sliding column, a support assembly provided on the outer wall of the device body, and a clamping assembly provided on the upper surface of the support platform;

[0007] The support assembly includes a second support frame, the outer wall of which is disposed on the outer wall of the device body. A second rotating shaft is fixedly connected to one end of the second support frame. A second fixed platform is rotatably connected to the outer wall of the second rotating shaft. A first fixed platform is fixedly connected to the outer wall of the device body. A first rotating shaft is rotatably connected to the inner wall of the first fixed platform. A hydraulic rod is fixedly connected to the outer wall of the first rotating shaft. A third rotating shaft is fixedly connected to the output end of the hydraulic rod. A spring is disposed on the outer wall of the second support frame. A third fixed platform is fixedly connected to one end of the spring. A support plate is fixedly connected to the lower surface of the third fixed platform. A connecting block is fixedly connected to the upper surface of the support plate.

[0008] Furthermore, the clamping assembly includes a fixed block, the lower surface of which is slidably connected to the upper surface of the support platform, a movable block fixedly connected to the outer wall of the fixed block, a bidirectional threaded rod II threadedly connected to the inner wall of the movable block, a handle fixedly connected to one end of the bidirectional threaded rod II, and a guide rod slidably connected to the inner wall of the movable block.

[0009] Furthermore, the outer wall of the second bidirectional threaded rod is threaded to the inner wall of the support platform, and the second bidirectional threaded rod is used to drive the moving block to move.

[0010] Furthermore, the outer wall of the guide rod is fixedly connected to the inner wall of the support platform, and the guide rod is used to guide the movement of the moving block.

[0011] Furthermore, the outer wall of the movable block is slidably connected to the inner wall of the support platform, and the movable block is used to drive the fixed block to move.

[0012] Furthermore, the upper surface of the lifting platform is slidably connected to the lower surface of the support platform, and the lifting platform is used to push the support platform to move.

[0013] Furthermore, the outer wall of the rotating shaft three is rotatably connected to one end of the support frame two, and the rotating shaft three is used to drive the support frame two to rotate.

[0014] Furthermore, the outer wall of the connecting block is fixedly connected to the inner wall of the second support frame, and the second support frame is used to drive the connecting block to move.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the hydraulic rod is activated, and its output end drives the rotating shaft three to rotate, causing the support frame two to rotate, which in turn drives the support plate to contact the ground. At this time, the spring tension plays a buffering role to prevent the device from tilting. After use, the hydraulic rod retracts, driving the support plate to rotate for storage. This solves the problem that when working with heavy vehicles or on uneven ground, the lack of additional support can easily lead to overall structural imbalance and swaying, affecting detection accuracy and potentially causing the car to slip off the lifting frame, causing a safety accident. This invention achieves the goals of preventing device tilting, improving detection accuracy, increasing work efficiency, enhancing safety, improving stability, and strengthening the overall load-bearing capacity of the lifting frame.

[0017] 2. In this utility model, by rotating the handle, the two-way threaded rod is driven to rotate, so that the moving block drives the fixed block to move relative to it under the restriction of the guide rod, thereby clamping and fixing the car tire. This effectively prevents the car from shifting during the inspection process, ensuring the accuracy and safety of the inspection, and avoiding inspection errors or safety accidents caused by the movement of the car.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a lifting frame for automobile testing, including a device body 1, a support frame 3 fixedly connected to the outer wall of the device body 1, a motor 4 fixedly connected to the upper surface of the support frame 3, a bidirectional threaded rod 5 fixedly connected to the output end of the motor 4, a lifting platform 7 threadedly connected to the outer wall of the bidirectional threaded rod 5, a guide column 6 slidably connected to the inner wall of the lifting platform 7, a sliding column 8 fixedly connected to the upper surface of the lifting platform 7, a support platform 2 slidably connected to the outer wall of the sliding column 8, a support assembly provided on the outer wall of the device body 1, and a clamping assembly provided on the upper surface of the support platform 2;

[0027] The support assembly includes a second support frame 10, the outer wall of which is set on the outer wall of the device body 1. One end of the second support frame 10 is fixedly connected to a second rotating shaft 15. The outer wall of the second rotating shaft 15 is rotatably connected to a second fixed platform 14. The outer wall of the device body 1 is fixedly connected to a first fixed platform 12. The inner wall of the first fixed platform 12 is rotatably connected to a first rotating shaft 13. The outer wall of the first rotating shaft 13 is fixedly connected to a hydraulic rod 11. The output end of the hydraulic rod 11 is fixedly connected to a third rotating shaft 17. The outer wall of the second support frame 10 is provided with a spring 19. One end of the spring 19 is fixedly connected to a third fixed platform 18. The lower surface of the third fixed platform 18 is fixedly connected to a support plate 9. The upper surface of the support plate 9 is fixedly connected to a connecting block 16.

[0028] Specifically, the support components on the outer wall of the device body 1 function to activate the hydraulic rod 11. The output end of the hydraulic rod 11 pushes the rotating shaft 17. Since the outer wall of the rotating shaft 17 is rotatably connected to one end of the support frame 10, the movement of the rotating shaft 17 causes the support frame 10 to rotate around the rotating shaft 15. When the support frame 10 rotates, the connecting block 16 moves accordingly, which in turn drives the support plate 9 to move. The support plate 9 moves down to contact the ground, providing additional support for the entire lifting frame and enhancing stability. At the same time, the spring 19 on the outer wall of the support frame 10 plays a role in buffering and fine-tuning the support force.

[0029] Reference Figure 1 , Figure 4 and Figure 5The clamping assembly includes a fixed block 22, the lower surface of which is slidably connected to the upper surface of the support platform 2. A movable block 21 is fixedly connected to the outer wall of the fixed block 22. A bidirectional threaded rod 24 is threadedly connected to the inner wall of the movable block 21. A handle 20 is fixedly connected to one end of the bidirectional threaded rod 24. A guide rod 23 is slidably connected to the inner wall of the movable block 21. The outer wall of the bidirectional threaded rod 24 is threadedly connected to the inner wall of the support platform 2. The bidirectional threaded rod 24 is used to drive the movable block 21 to move. The outer wall of the guide rod 23 is fixedly connected to the inner wall of the support platform 2. The guide rod 23 is used to guide the movement of the moving block 21. The outer wall of the moving block 21 is slidably connected to the inner wall of the support platform 2. The moving block 21 is used to drive the fixed block 22 to move. The upper surface of the lifting platform 7 is slidably connected to the lower surface of the support platform 2. The lifting platform 7 is used to push the support platform 2 to move. The outer wall of the rotating shaft 17 is rotatably connected to one end of the support frame 10. The rotating shaft 17 is used to drive the support frame 10 to rotate. The outer wall of the connecting block 16 is fixedly connected to the inner wall of the support frame 10. The support frame 10 is used to drive the connecting block 16 to move.

[0030] Specifically, by rotating the handle 20, the handle 20 drives the double-threaded rod 24 to rotate. The outer wall of the double-threaded rod 24 is threadedly connected to the inner wall of the support platform 2, and one end of it is threadedly connected to the moving block 21. Therefore, when the double-threaded rod 24 rotates, it drives the moving block 21 to move. The inner wall of the moving block 21 is slidably connected to the guide rod 23, and the outer wall of the guide rod 23 is fixedly connected to the inner wall of the support platform 2. The guide rod 23 ensures that the moving block 21 can only move along the direction of the guide rod 23. When the moving block 21 moves, it drives the fixed block 22 fixedly connected to it to move. By adjusting the position of the fixed block 22, the car tire can be clamped and fixed to prevent the car from shifting during the inspection process.

[0031] Working principle: When a lifting frame for vehicle inspection is needed, motor 4 is first started, and its output end drives the bidirectional threaded rod 5 to rotate. When the bidirectional threaded rod 5 rotates, it drives the lifting platform 7 to move. The lifting platform 7 is guided by the guide column 6. At this time, the lifting platform 7 pushes the support platform 2 to start lifting and lowering. The sliding column 8 slides inside the support platform 2, thus realizing lifting and lowering. When the device deviates, hydraulic rod 11 is first started, and its output end drives the rotating shaft 17 to rotate. Hydraulic rod 11 rotates through rotating shaft 13, and rotating shaft 17 drives the support frame 10 to start rotating. When the output end of hydraulic rod 11 is fully extended, it drives the support plate 9 to rotate. At this time, spring 19 is stretched. When the support plate 9 contacts the ground, it provides support and prevents deviation. To prevent the device from tilting, after use, the output end of the hydraulic rod 11 retracts to move the rotating shaft 17. The rotating shaft 17 drives the support frame 10 to rotate. At this time, the spring 19 retracts to drive the support plate 9 to rotate, thus realizing the storage of the support assembly. In addition, by turning the handle 20, the handle 20 drives the bidirectional threaded rod 24 to rotate. The bidirectional threaded rod 24 drives the support platform 2 to move. The moving block 21 drives the fixed block 22 to move relative to it. The guide rod 23 ensures that the moving block 21 can only move along the direction of the guide rod 23. When the moving block 21 moves, it drives the fixed block 22 that is fixedly connected to it to move. By adjusting the position of the fixed block 22, the car tire can be clamped and fixed to prevent the car from shifting during the inspection process.
