Description

Technical Field

[0001] The utility model relates to the technical field of vehicle detection, in particular to a lifting device used for vehicle detection. Background Art

[0002] With the rapid development of the automotive industry and the increasing number of cars on the road, the demand for vehicle repair and maintenance is also growing. During vehicle repairs, it's often necessary to lift the car to a certain height so that repair personnel can work underneath it. Consequently, vehicle lifts have become essential equipment for auto repair shops and 4S stores. Consequently, there's an urgent need for a vehicle lift for inspection.

[0003] However, the prior art still has the following problems:

[0004] First of all, most traditional lifting devices use two lifting plates, which are used to move the tires on both sides of the vehicle to the two lifting plates respectively before lifting. If the weight distribution on both sides of the vehicle is uneven, the rising speed of the lifting plate on one side may be out of sync with that on the other side, seriously affecting the stability of the lifting.

[0005] Secondly, traditional lifting devices may lack effective anti-skid and anti-slip measures, and the vehicle is at risk of sliding when lifted. If the vehicle slides, it will not only cause serious damage to the vehicle itself, but may also endanger the life safety of the inspection personnel.

[0006] In response to the above problems, the inventors propose a lifting device for vehicle detection to solve the above problems. Utility Model Content

[0009] Preferably, a rectangular groove is provided at the top of the lifting frame, and four springs are fixedly connected to the lower inner wall of the rectangular groove. The four springs are distributed at equal intervals. The equally spaced springs can provide a consistent buffering effect. In the process of the vehicle entering the lifting frame, a certain impact force may be generated, and the function of the spring is to absorb and alleviate this impact force. The top ends of the four springs are jointly fixedly connected to an anti-slip plate, and the top edge of the lifting frame is fixedly connected to the anti-slip frame. Two insertion rods are movably inserted at both ends of the anti-slip frame, and the two insertion rods respectively pass through the two ends of the anti-slip frame and are movably connected to the two ends of the anti-slip plate.

Both ends of the anti-slip plate are fixedly connected to sliders used in conjunction with the sliding grooves.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This utility model realizes synchronous lifting of the entire structure by setting a lifting mechanism. With multiple fixed blocks and lifting rods driving the lifting frame to rise and fall, it reduces the imbalance problem caused by independent lifting of both sides and greatly improves the lifting stability.

[0012] 2. The utility model provides an anti-slip plate. Under the action of the anti-slip frame, anti-slip plate and spring and other structures provided on the top of the lifting frame, the vehicle can be effectively prevented from sliding down when it is lifted, thereby improving the safety of the vehicle and the life safety of the inspection personnel.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: Figure 1-3As shown, the utility model provides a lifting device for vehicle inspection, including a base plate 1, the top of the base plate 1 is fixedly connected to a lifting mechanism 5, the lifting mechanism 5 includes a lifting frame 2, the top of the base plate 1 is fixedly connected to a stepping plate 18, the stepping plate 18 is located just below the lifting frame 2, providing a stable standing position for the inspection personnel, facilitating the inspection personnel to better observe and control the lifting process when operating the lifting device, thereby improving the safety and convenience of the operation, the lifting frame 2 is parallel to the base plate 1, and a through-type detection slot 4 is provided at the bottom end of the lifting frame 2. The parallel distribution of the lifting frame 2 and the base plate 1 ensures the stability of the lifting process and reduces the lifting The rocking and tilting during the lifting process improve the accuracy and safety of the detection. The through-type detection slot 4 provides a convenient detection channel for the detection equipment. The detection personnel can more conveniently conduct a comprehensive detection of the bottom of the vehicle, thereby improving the detection efficiency. The top of the lifting frame 2 is fixedly connected with an anti-slip pad 6 to increase the friction between the vehicle and the lifting frame 2 to prevent the vehicle from sliding in the lifted state. One end of the lifting frame 2 is fixedly connected with a boarding frame 8, which provides a transition channel for the vehicle, so that the vehicle can be driven onto the lifting frame 2 more steadily and smoothly. The lower inner wall of the lifting frame 2 and the top of the bottom plate 1 are fixedly connected with four fixing blocks 19, and the corresponding two fixing blocks 19 is connected to the lifting rod 12 for rotation, and the two adjacent lifting rods 12 are connected to each other for rotation. The lower inner wall of the lifting frame 2 and the top of the bottom plate 1 are fixedly connected with four support blocks 14. The corresponding two support blocks 14 are fixedly connected with a slide rod 16. The corresponding two slide rods 16 are slidably sleeved with a movable plate 11. The bottom end of the bottom plate 1 is fixedly connected to the motor 17. The output end of the motor 17 is fixedly connected with a threaded rod 15. The end of the threaded rod 15 facing away from the motor 17 is fixedly connected to a limit block 13 to prevent the movable plate 11 from separating from the threaded rod 15 during movement, thereby ensuring the stable operation of the lifting device. The outer surface of the threaded rod 15 is fixed to the bottom plate 17. The movable plate 11 at the bottom is threadedly connected. When the vehicle needs to be inspected, the vehicle is driven onto the lifting frame 2 through the boarding frame 8, and the motor 17 is started. The output end of the motor 17 drives the threaded rod 15 to rotate. Under the rotation of the threaded rod 15, the movable plate 11 moves along the sliding rod 16. The movement of the movable plate 11 will push the lifting rod 12 to move. Because the two ends of the lifting rod 12 are respectively rotatably connected to the fixed blocks 19 on the base plate 1 and the lifting frame 2, and the adjacent lifting rods 12 are rotatably connected to each other, the lifting frame 2 is gradually lifted as the movable plate 11 moves. During the inspection process, the inspector can stand on the stepping plate 18 at the top of the base plate 1 to inspect the vehicle.

[0021] The top of the lifting frame 2 is provided with a rectangular groove 34, and the lower inner wall of the rectangular groove 34 is fixedly connected with four springs 33. The tops of the four springs 33 are fixedly connected with an anti-slip plate 7. The top edge of the lifting frame 2 is fixedly connected with the anti-slip frame 3. Two insertion rods 32 are movably inserted at both ends of the anti-slip frame 3. The two insertion rods 32 respectively pass through the two ends of the anti-slip frame 3 and are movably sleeved with the two ends of the anti-slip plate 7. The two ends of the anti-slip plate 7 are respectively slidably connected to the inner walls of the two sides of the rectangular groove 34. The inner walls of the two sides of the rectangular groove 34 are provided with sliding grooves 35. Both ends of the anti-slip plate 7 are fixedly connected with sliding grooves 35 for use. The block 31 ensures that the anti-slip plate 7 can slide smoothly during operation, thereby improving the reliability of the anti-slip plate 7. Before the vehicle passes the boarding frame 8 to the lifting frame 2, the two insertion rods 32 are first pulled out. The setting of the four springs 33 allows the anti-slip plate 7 to return to its original position quickly after the vehicle passes the anti-slip plate 7. After the vehicle drives onto the lifting frame 2, the two insertion rods 32 are respectively inserted, which can effectively prevent the vehicle from sliding. The anti-slip pad 6 at the top of the lifting frame 2 can increase the friction between the vehicle and the lifting frame 2 to prevent the vehicle from sliding. The sliders 31 at both ends of the anti-slip plate 7 cooperate with the sliding grooves 35 on the inner walls of both sides of the rectangular groove 34 to ensure that the anti-slip plate 7 can slide smoothly.

[0022] Working principle: When a vehicle needs to be inspected, the vehicle is driven onto the lifting frame 2 through the boarding frame 8, and the motor 17 is started. The output end of the motor 17 drives the threaded rod 15 to rotate. Under the rotation of the threaded rod 15, the movable plate 11 moves along the slide rod 16. The movement of the movable plate 11 pushes the lifting rod 12 to move. Because the two ends of the lifting rod 12 are respectively rotatably connected to the fixed blocks 19 on the base plate 1 and the lifting frame 2, and the adjacent lifting rods 12 are rotatably connected to each other, the lifting frame 2 is gradually lifted as the movable plate 11 moves. During the inspection process, the inspector can stand on the stepping plate 18 at the top of the base plate 1 to inspect the vehicle.

[0023] When the vehicle passes the boarding frame 8 and moves to the front of the lifting frame 2, first pull out the two insertion rods 32. The arrangement of the four springs 33 allows the anti-slip plate 7 to return to its original position quickly after the vehicle passes the anti-slip plate 7. After the vehicle moves onto the lifting frame 2, the two insertion rods 32 are respectively inserted to effectively prevent the vehicle from sliding. The anti-slip pad 6 at the top of the lifting frame 2 can increase the friction between the vehicle and the lifting frame 2 to prevent the vehicle from sliding. The sliders 31 at both ends of the anti-slip plate 7 cooperate with the slide grooves 35 on the inner walls of the two sides of the rectangular groove 34 to ensure that the anti-slip plate 7 can slide smoothly.

[0024] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
