At the same time, the lifting plate blocks the bottom of the car, which is not convenient for maintenance personnel to inspect the car chassis. Therefore, we need to propose a lifting device for car detection. Utility Model Content

[0023] Please refer to Figures 1-3 , the present utility model provides a technical solution: a lifting device for vehicle detection, including:

[0024] A frame 100, a lifting mechanism 300 disposed on the top of the frame 100, the lower ends of the lifting mechanism 300 are disposed on both sides of the inner cavity of the frame 100, and a control panel 200 is disposed on one side of the frame 100;

[0025] A bearing mechanism 400 is disposed at the lower end of the lifting mechanism 300. The bearing mechanism 400 is disposed in the inner cavity of the frame 100. Four sets of position-limiting members 600 for fixing tires are disposed above the bearing mechanism 400. Each two sets of position-limiting members 600 are correspondingly provided with a position-limiting mechanism 500.

[0026] The limiting mechanism 500 includes a sliding rod 501 and sliders 502 slidably inserted at both ends of the sliding rod 501, one side of the two sets of sliders 502 are fixedly connected to a support block 503, a cylinder 504 is installed on the upper end of one side of the support block 503, a switch 506 is provided on the lower end of one side of the support block 503, and the telescopic end of the cylinder 504 passes through the support block 503 and is fixedly connected to a top plate 505 for fixing the tire.

[0027] The limiting member 600 includes a tire contact block 601 and a tooth block 602. The tooth block 602 is fixedly connected to the lower surface of the tire contact block 601. The cross-section of the tire contact block 601 is larger than the cross-section of the tooth block 602. The tooth block 602 is convenient for fitting with the teeth in the upper slide groove 406, thereby facilitating the fixation of the tire contact block 601 and improving the effect of fixing the tire.

[0028] The bearing mechanism 400 includes two groups of lifting plates 401 and two groups of connecting beams 404. Bottom grooves 403 for the two groups of connecting beams 404 to be embedded are provided at both ends of the lower surfaces of the two groups of lifting plates 401, and the two groups of connecting beams 404 are detachably connected to the two groups of lifting plates 401. Baffles 405 are fixedly connected to the opposite ends of the upper surfaces of the two groups of lifting plates 401. The baffles 405 prevent the position of the car from shifting when it drives onto the lifting plates 401, facilitate the angle alignment of the tires, and improve the efficiency of limiting the tires.

[0029] The upper surfaces of the two sets of lifting plates 401 are provided with upper sliding grooves 406 for sliding connection of the two sets of limiting members 600, and the bottom of the upper sliding grooves 406 is provided with teeth that fit with the tooth blocks 602. The opposite sides of the two sets of lifting plates 401 are provided with side sliding grooves 407 for sliding connection of the sliders 502.

The load-bearing base plate 101 increases the contact area between the frame 100 and the ground, thereby improving the stability of the frame 100 after installation. In addition, the multiple groups of reinforcement blocks 103 improve the stability of the gantry 102 to prevent the connection between the gantry 102 and the load-bearing base plate 101 from being disconnected when lifting a car.

[0031] The lifting mechanism 300 includes a dual-axis motor 301, multiple groups of bearing seats 302 and two groups of screws 306.

The two groups of rotating shafts 303 are rotatably connected inside the multiple groups of bearing seats 302. The upper ends of the two groups of screws 306 penetrate the gantry 102 and are fixedly connected with a second bevel gear 305. The opposite ends of the two groups of rotating shafts 303 are fixedly connected with a first bevel gear 304 meshing with the second bevel gear 305. The rotating shaft 303 is driven by the dual-axis motor 301, and then the first bevel gear 304 meshes with the second bevel gear 305, so that the screw 306 drives the guide block 402 to rise and fall, which is convenient for lifting and lowering the car on the lifting plate 401, and the operation is simple.

[0032] Both ends of the inner cavity of the gantry 102 are fixedly connected with guide rods 307, and the guide rods 307 are arranged in parallel with the screw rods 306. The two sets of lifting plates 401 and the side slide grooves 407 are fixedly connected with guide blocks 402 threadedly connected to the screw rods 306 on the opposite side. The upper surface of the guide block 402 is provided with a through hole for the guide rods 307 to slide and insert. The guide rods 307 are used to improve the stability of the lifting of the lifting plates 401.

[0033] When in use, the carrying mechanism 400 is located on the upper surface of the load-bearing base plate 101, and the vehicle is moved onto the lifting plate 401 along the inclined portion of the lifting plate 401. The staff first inserts the limiting member 600 into the upper slide groove 406, thereby making the concave surface of the tire contact block 601 contact the tire, and then the teeth of the upper slide groove 406 fit with the tooth block 602, thereby improving the front and rear positioning of the automobile tire, and controlling the lifting mechanism 300 through the control panel 200 to lift the carrying mechanism 400 to improve the stability of the automobile when it is lifted. After the automobile is lifted, the maintenance personnel move the limiting mechanism 500 corresponding to the front and rear tires, and then control the top plate 505 on the cylinder 504 through the switch 506 to contact the inner side of the tire, thereby realizing the left and right positioning of the automobile, avoiding the movement of the automobile during the detection process, and improving the safety of the detection. At the same time, the distance between the two sets of lifting plates 401 is convenient for the staff to detect the bottom of the automobile, thereby improving the detection efficiency.
