[0002] With the rapid development of the automobile industry, the number of automobiles is increasing, and the automobile maintenance industry is also growing. In the process of automobile maintenance, lifting equipment is often used to lift the automobile so that the maintenance personnel can check and maintain the bottom of the automobile. For small repair workshops, two-column lifting machines are one of the most commonly used automobile lifting equipment. The two-column lifting machine is mainly composed of two columns, a lifting slide, a supporting arm and the like. The operator moves the automobile between the two columns and manually adjusts the supporting arm under the vehicle chassis, and then runs the hydraulic rod to push the lifting slide to realize the lifting of the vehicle. However, this two-column lifting machine completely relies on manual movement of the vehicle and adjustment of the supporting arm, which not only has high requirements for the experience and skills of the operator, but also is prone to inaccurate position of the supporting arm due to human error, thereby affecting the lifting stability. On the other hand, the two-column lifting machine is only supported and limited by the two columns on the sides, so the lifting slide is prone to shaking the whole vehicle when continuing to lift the vehicle, thereby causing the vehicle to overturn, increasing the risk of the operator when repairing the automobile, and reducing the repair efficiency.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0016] As Figures 1 to 8 shown, the present application provides a vehicle maintenance lifting device with automatic correction of vehicles, comprising a support assembly 1 and a hydraulic support 5 for lifting the support assembly 1, the support assembly 1 comprising a connecting plate 11 and adjusting seats 12 arranged on both sides thereof, further comprising: a synchronous assembly 2 installed on the connecting plate 11 for synchronously and oppositely moving the two adjusting seats 12; The adjusting seat 12 comprises support seats 121 arranged on both sides of the connecting plate 11, and the opposite sides of the two support seats 121 are fixedly connected with a limiting plate 122 and an elastic damping limiting rod 123 located inside the connecting plate 11, the limiting plate 122 is movably connected inside the connecting plate 11, and the elastic damping limiting rod 123 is elastically connected inside the connecting plate 11 for enabling the support seat 121 to have a tendency to move towards the connecting plate 11; The support seat 121 is further movably installed with a support damping roller set one 1211 and a support damping roller set two 1213, the support damping roller set one 1211 and the support damping roller set two 1213 are inclined towards the opposite sides, The support seat 121 is further elastically supported with an elastic support 124, the top of the elastic support 124 is fixedly connected with a support grid 1241, the grid plate part of the support grid 1241 passes through the gap between the roller shafts of the support damping roller set one 1211 and the support damping roller set two 1213 upwards, and the top end of the grid plate part of the support grid 1241 is at the same height plane as the top of the connecting plate 11 and the adjusting seat 12. The two support seats 121 on the same connecting plate 11 are inclined on the opposite side, and the bottom of the connecting plate 11 and the support seat 121 are in contact with the ground in the initial state; The synchronous assembly 2 comprises a gear 22 movably connected to the support assembly 1, and the gear 22 is movably connected with the connecting plate 11 through a rack 21 arranged above and below the gear 22; The two racks 21 are fixedly connected with the two support seats 121 at the opposite ends, respectively; By using the above scheme, the support assembly 1 is driven to move upward by the hydraulic support 5, at this time, the support grid 1241 is pressed downward under the action of the gravity of the vehicle, and the vehicle tires will contact the support damping roller set two 1213 or the support damping roller set one 1211, when one of the vehicle tires is on the support damping roller set one 1211, the vehicle wheel will force one of the support seats 121 and the rack 21 to move away from the connecting plate 11, and the other rack 21 will drive the other support seat 121 to move synchronously and oppositely through the rotation of the gear 22, since each roller shaft on the support damping roller set two 1213 or the support damping roller set one 1211 will rotate, at this time, the two groups of vehicle wheels will move along the support damping roller set two 1213 or the support damping roller set one 1211, finally, the two groups of vehicle wheels are supported by the bottom ends of the support damping roller set two 1213 and the support damping roller set one 1211 and the relative position is kept unchanged, at the same time, the stability of the vehicle in the lifting process is ensured; Further, when the two support seats 121 move oppositely, the limiting plate 122 extends outward. When the driving hydraulic support 5 moves reversely and resets the support assembly 1, the bottom of the elastic support 124 will first contact the ground, then the support seat 121, the support damping roller set one 1211 and the bent block 1212 will continue to move downward until they contact the ground, in this process, the support grid 1241 will gradually replace the support damping roller set one 1211 and the bent block 1212 to support the vehicle tires, then the vehicle moves reversely, since the support seat 121 will have a gap with the connecting plate 11 at this time, the limiting plate 122 can support the vehicle to facilitate the vehicle to move out reversely; It is worth noting that the initial distance between the two groups of support damping roller set two 1213 and the support damping roller set one 1211 is smaller than the distance between the front and rear tires of a general vehicle, by using this design, it can be ensured that at least one group of vehicle tires is on the support damping roller set one 1211.

[0017] As shown in Figures 1-3 The top of the connecting plate 11 is further provided with a through hole 111 in communication with the piston end of the elastic damping limiting rod 123; the diameter of the through hole 111 is smaller than the diameter of the cross section of the piston part of the elastic damping limiting rod 123; With the above scheme, when the device is reset, the vehicle will be separated from the support assembly 1, at this time the support seat 121 will be reset under the action of the spring force outside the elastic damping limiting rod 123, at this time the piston part of the elastic damping limiting rod 123 will discharge the gas in the connecting plate 11 through the through hole 111, since the diameter of the through hole 111 is smaller than the diameter of the piston of the elastic damping limiting rod 123, at this time the speed of the elastic damping limiting rod 123 will be slowed down, thereby avoiding the impact between the support seat 121 and the connecting plate 11 or the impact on the person.

[0018] As shown in Figures 2-6 One of the support seats 121 is hinged with a bent block 1212 near one end of the connecting plate 11; the upper surface of the bent block 1212 at the end inside the support seat 121 is at the same height as the top surface of the support seat 121; The other end of the bent block 1212 is above the connecting plate 11 and is initially in an inclined state, the bent block 1212 can rotate to make the end above the connecting plate 11 rotate into the connecting plate 11, and the upper surface of the other end of the bent block 1212 inclines towards the connecting plate 11; With the above scheme, the vehicle is moved above the support assembly 1, when the front wheels of the vehicle contact the bent block 1212, the bent block 1212 is pressed to rotate, so that the part of the bent block 1212 above the connecting plate 11 rotates into the connecting plate 11, at this time the other end of the bent block 1212 will be raised, thereby ensuring that the front and rear wheels of the vehicle can be located above the two support grilles 1241 respectively, thereby facilitating the positioning of the subsequent vehicle; Further, when the vehicle is reset, the front wheels will press the part of the bent block 1212 away from one end of the support seat 121 and make it rotate to the initial state.

[0019] As shown in Figures 1-3 and Figures 7-8 The jacking assembly 3 includes a driving assembly 31 fixedly installed in the middle of the connecting plate 11 and a limiting cross rod 35 fixedly installed on both sides of the connecting plate 11; a sliding block 32 movably connected inside the connecting plate 11 and sleeved outside the limiting cross rod 35; a connecting rod one 33 symmetrically hinged to the end of the sliding block 32 away from the driving assembly 31; The driving assembly 31 is used to drive the two sliding blocks 32 to move, the top of the connecting rod one 33 is hinged with a top plate 36 movably connected with the connecting plate 11, and the top surface of the top plate 36 is initially at the same height as the top surface of the connecting plate 11; With the above scheme, by driving the two groups of sliding blocks 32 to move away from each other by operating the driving assembly 31, the top end of the connecting rod one 33 lifts the top plate 36, at this time the upward movement of the top plate 36 lifts the part of the chassis between the front and rear wheels of the vehicle, thereby making the tire part of the vehicle separate from the contact with the support damping roller group one 1211, thereby facilitating the maintenance or replacement of the vehicle wheel part by the operator.

[0020] As shown in Figure 3 and Figures 7-8 The connecting plate 11 is also symmetrically hinged with a telescopic connecting rod 34 below the top plate 36, and the bottom end axis of the telescopic connecting rod 34 is the rotating shaft 341; the top end of the telescopic connecting rod 34 is hinged with the top plate 36; the connecting rod 33 and the telescopic connecting rod 34 are cross and staggered arranged; The connecting plate 11 is also symmetrically and movably connected with a rubber pressing block 4, which is movably sleeved on one end of the rotating shaft 341; The rotating shaft 341 is also circumferentially arrayed and provided with a guide groove 3411, and the rubber pressing block 4 is internally fixedly connected with a plurality of convex shafts 41 which can slide in the guide groove 3411, and the convex shaft 41 is initially located at one end of the guide groove 3411 close to the telescopic connecting rod 34; The rubber pressing block 4 close to the limiting plate 122 is arc-shaped, and the rubber pressing block 4 can extrude the limiting plate 122 when moving towards the limiting plate 122; By using the above scheme, the driving assembly 31 drives the slider 32 to make the top plate 36 go up, and also makes the top plate 36 drive the top end of the telescopic connecting rod 34 to go up, so that the telescopic connecting rod 34 rotates and drives the rotating shaft 341 to rotate, so that the guide groove 3411 forces the convex shaft 41 to move and drive the rubber pressing block 4 to move towards the limiting plate 122 and generate deformation to fix the limiting plate 122, so as to ensure that after the top plate 36 is removed from the vehicle, the vehicle tire is still between the support damping roller group one 1211 and the support damping roller group two 1213.

[0021] The working principle and use process of the present application are as follows: First, the operator moves the vehicle above the support assembly 1, and when the front wheels of the vehicle contact the bent block 1212, the bent block 1212 will be extruded and rotated, so that the part of the bent block 1212 above the connecting plate 11 is rotated into the connecting plate 11, and at this time the other end of the bent block 1212 will be raised, so that the front and rear wheels of the vehicle can be located above the two support grilles 1241 respectively, thereby facilitating the positioning of the subsequent vehicle; Subsequently, the hydraulic support 5 drives the support assembly 1 to move upwards, at this time, due to the gravity of the vehicle, the tires will press the support grid 1241 to move downwards, and the vehicle tires will contact the support damping roller set two 1213 or the support damping roller set one 1211, when one set of tires on the vehicle is on the support damping roller set one 1211, the wheels will force the support seat 121 to move away from the connecting plate 11, and under the action of the synchronous assembly 2, the other support seat 121 is synchronously and oppositely moved, and at this time, each roller shaft on the support damping roller set two 1213 or the support damping roller set one 1211 rotates, at this time, the two sets of wheels move along the support damping roller set two 1213 or the support damping roller set one 1211, finally, the two sets of wheels are supported by the bottom ends of the support damping roller set two 1213 and the support damping roller set one 1211 and the relative positions are kept unchanged, and the overall vehicle is always kept in the center position on the support assembly 1; When it is necessary to replace or repair the vehicle tires, the operator drives the driving assembly 31 to drive the two sets of sliders 32 to move away from each other, so that the top plate 36 is lifted by the top end of the connecting rod one 33, at this time, the upward movement of the top plate 36 lifts the chassis part between the front and rear wheels of the vehicle, so that the tire part of the vehicle is separated from the contact with the support damping roller set one 1211. Before the top plate 36 lifts the vehicle, the top end of the telescopic connecting rod 34 is also lifted, so that the telescopic connecting rod 34 rotates, at this time, the telescopic connecting rod 34 also rotates the rotating shaft 341, so that the guide groove 3411 forces the convex shaft 41 to move and drives the rubber pressing block 4 to move towards the limiting plate 122 and deform to fix the limiting plate 122, so that after the top plate 36 is lifted, the vehicle tires are still between the support damping roller set one 1211 and the support damping roller set two 1213.
