Technical Field

[0001] This utility model relates to the field of automotive testing technology, specifically a lifting frame for automotive testing. Background Technology

[0002] Currently, when vehicles are lifted and inspected using a lifting bracket, the structural limitations of the bracket mean that when a vehicle is raised or lowered rapidly, the force generated by the vehicle's acceleration affects the structural stability of the lifting bracket. This results in existing lifting brackets only being able to raise and lower slowly, which affects the speed of vehicle inspection. Utility Model Content

[0003] The purpose of this invention is to provide a lifting frame for automobile inspection, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A lifting frame for vehicle inspection includes a base with an inspection and observation port inside. Fixed frames are fixedly connected to both sides of the base. A lifting groove is provided within the fixed frames, and a lifting seat is slidably connected within the lifting groove.

Sliding limiting grooves are provided on both sides of the lifting groove, and a first lifting frame and a second lifting frame are slidably connected within the sliding limiting grooves. A connecting rod is fixedly connected between the first and second lifting frames. A buffer damping rod is fixedly installed on the lifting seat, and its input end is fixedly connected to the first lifting frame. A rotating connecting block is fixedly connected to the top of the second lifting frame. A rotating power arm is provided between the first and second lifting frames. A first fixed shaft is fixedly connected to the bottom of the rotating power arm and is rotatably connected to the rotating connecting block. A second fixed shaft is fixedly connected to one end of the rotating power arm and is located within the adjustment limiting groove. A connecting frame is fixedly connected to the other end of the rotating power arm, and a lifting platform is fixedly connected to the connecting frame. The lifting platform is located within the inspection and observation port.

Detailed Implementation

[0015] 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.

[0016] See Figures 1-3In this embodiment of the present invention, a lifting frame for vehicle inspection includes a base 1, with an inspection observation port 3 inside the base 1. Fixed frames 4 are fixedly connected to both sides of the base 1. A lifting groove 5 is provided inside the fixed frame 4. A lifting seat 8 is slidably connected inside the lifting groove 5. A connecting seat 9 is fixedly connected to the bottom of the lifting seat 8. An adjusting limiting groove 10 is fixedly connected to the bottom of the connecting seat 9. A hydraulic telescopic pump 7 is fixedly connected to the top of the fixed frame 4. The output end of the hydraulic telescopic pump 7 is fixedly connected to the lifting seat 8. Sliding limiting grooves 6 are provided on both sides of the lifting groove 5. A first lifting frame 12 and a second lifting frame 14 are slidably connected inside the sliding limiting grooves 6. A connecting rod 1 is fixedly connected between the first lifting frame 12 and the second lifting frame 14. 3. A buffer damping rod 11 is fixedly installed on the lifting seat 8. The input end of the buffer damping rod 11 is fixedly connected to the first lifting frame 12. A rotating connecting block 15 is fixedly connected to the top of the second lifting frame 14. A rotating power arm 16 is provided between the first lifting frame 12 and the second lifting frame 14. A first fixed shaft 17 is fixedly connected to the bottom of the rotating power arm 16. The first fixed shaft 17 is rotatably connected to the rotating connecting block 15. A second fixed shaft 18 is fixedly connected to one end of the rotating power arm 16. The second fixed shaft 18 is set in the adjustment limit groove 10. A connecting frame 19 is fixedly connected to the other end of the rotating power arm 16. A lifting platform 20 is fixedly connected to the connecting frame 19. The lifting platform 20 is set in the detection and observation port 3. In operation, this invention first uses a hydraulic telescopic pump 7 to raise and lower the lifting seat 8, which in turn lowers the lifting platform 20 into the detection observation port 3. At this point, the vehicle can be driven onto the base 1, and its wheels can be fixed to the lifting platform 20. Then, the hydraulic telescopic pump 7 raises the lifting platform 20. The vehicle's weight acts on the lifting platform 20, converting it into a tilting driving force. The lifting platform 20 uses the first fixed shaft 17 and the rotating connecting block 15 as fulcrums, and the rotating power arm 16 as a lever, to leverage the downward force acting on the lifting platform 20. The rotational driving force is converted into an upward rotational driving force on the side of the rotating power arm 16 away from the lifting platform 20. This upward rotational driving force is then counteracted by the hydraulic telescopic pump 7. At the same time, the rotating power arm 16 also applies a set of downward pressure to the second lifting frame 14 through the first fixed shaft 17 and the rotating connecting block 15. The pressure acts on the buffer damping rod 11 through the connecting rod 13 and the first lifting frame 12. The buffer damping rod 11 then buffers and absorbs the downward pressure, thereby buffering and absorbing the force generated by the acceleration during the vehicle's lifting process, and thus improving the stability of the vehicle during the lifting process.

[0017] In one embodiment, as shown in Figures 1 and 2, a ball bearing slider 24 is fixedly connected to the side of the lifting platform 20 near the inner wall of the base 1, and a ball bearing groove 25 is provided on the side of the fixing frame 4 near the lifting platform 20. The ball bearing slider 24 and the ball bearing groove 25 cooperate with each other. This utility model uses the cooperation between the ball bearing groove 25 and the ball bearing slider 24 to laterally fix the lifting platform 20 and the fixing frame 4, thereby limiting the downward rotation of the lifting platform 20 and enhancing the structural stability of the lifting platform 20.

[0018] In one embodiment of this invention, please refer to Figures 1 and 2. The base 1 is provided with ramps 2 at both ends. The present invention facilitates the entry and exit of vehicles by providing ramps 2.

[0019] In one embodiment, referring to Figures 2 and 3, the lifting platform 20 is fixedly connected to two ends with flipping limit frames 21. One set of flipping limit frames 21 is provided with a slot 22, and the other set of flipping limit frames 21 is fixedly connected with a locking rod 23, which is disposed in the slot 22. When the vehicle drives onto the lifting platform 20, the vehicle's gravity acts on the lifting platform 20, thereby converting the vehicle's gravity into a flipping driving force for the lifting platform 20, which in turn drives the lifting platform 20 to flip and fold downwards. The lifting platform 20 drives the two sets of tilting limit frames 21 to fold inward and rotate. The tilting limit frames 21 then drive the locking rod 23 to slide relative to each other in the slot 22. When the lifting platform 20 is unfolded, the locking rod 23 moves to the bottom of the slot 22. At this time, the locking rod 23 and the slot 22 limit each other, and the locking rod 23 and the slot 22 can no longer slide relative to each other. This limits and fixes the two sets of tilting limit frames 21, thereby offsetting the rotational driving force on the lifting platform 20 and enhancing the load-bearing capacity of the lifting platform 20.
