Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1:

[0035] As Figures 1-6As shown in the figure, an embodiment of the present invention provides a lift for automobile maintenance and disassembly, including: a fixed column 1, a lifting plate 2, a handle frame 3, and a ladder frame 4. The number of fixed columns 1 is four. First sliding grooves 101 are respectively provided inside the fixed columns 1. Sliders 201 are slidably engaged inside the first sliding grooves 101. During the lifting process of the lifting plate 2, the sliders 201 are slidably engaged with the first sliding grooves 101 to increase stability. The inner sides of the sliders 201 are fixedly connected to the lifting plate 2. Both sides of the bottom ends of the fixed columns 1 are fixedly connected with bottom plates 7. Chute plates 701 are fixedly connected to one end above the bottom plates 7 and the bottom ends of the lifting plate 2 respectively. Diagonal braces 6 are rotatably connected inside the chute plates 701. Through the cross-rotation action of the diagonal braces 6, the lifting plate 2 can be lifted. The number of diagonal braces 6 is two and they are cross-arranged. The other ends of the diagonal braces 6 are respectively rotatably engaged with the upper part of the bottom plate 7 and the bottom end of the lifting plate 2. A first connecting rod 5 is fixedly connected between one side of a group of diagonal braces 6 close to the chute plate 701. A second connecting rod 503 is fixedly connected between one side of the middle part of the other group of diagonal braces 6 above the first connecting rod 5. The two ends of the first connecting rod 5 are respectively rotatably connected with first rotating blocks 501. The two ends of the second connecting rod 503 are respectively rotatably connected with second rotating blocks 504. A hydraulic cylinder 502 is fixedly connected between the first rotating block 501 and the second rotating block 504. When the hydraulic cylinder 502 extends, since both ends of the hydraulic cylinder 502 are rotatably engaged, after support, the other group of diagonal braces 6 can be hydraulically pushed, thus completing the lifting function;

[0036] Second sliding grooves 202 are respectively provided inside the lifting plate 2. T-shaped grooves 204 are provided inside the second sliding grooves 202. T-shaped blocks 2031 are slidably engaged inside the T-shaped grooves 204. Workers can perform maintenance and disassembly work at the bottom end of the lifting plate 2. When the cross plate 203 affects the installation of parts during the disassembly process, the cross plate 203 can be slid. Since both ends of the cross plate 203 adopt the sliding fit of the T-shaped blocks 2031 and the T-shaped grooves 204, the position can be slid and adjusted as required. The cross plate 203 is fixedly connected between the T-shaped blocks 2031. The cross plate 203 is arranged between the lifting plates 2 during the lifting process, and the stability of the two lifting plates 2 is increased through the cross plate 203. Baffles 205 are fixedly connected to the ends of the lifting plate 2, and the baffles 205 are used to resist and limit the vehicle;

[0037] A horizontal fixed plate 401 is fixedly connected to the top of the fixed columns 1 on one side, and a ladder frame 4 is fixedly connected to one side of the horizontal fixed plate 401. The staff can climb into the top of the lifting platform 2 through the ladder frame 4 to check the vehicle's fault problems. There is no need to repeatedly adjust the lifting and lowering of the lifting platform 2, which reduces the lifting operation. The four corners of the outer side of the fixed columns 1 are fixedly connected to the mounting seats 102, and the bottom ends between the front fixed columns 1 are fixedly connected to the L-shaped fixed plate 103. The inner side of the L-shaped fixed plate 103 is consistent with the height of the lifting platform 2 after recovery. The front ends of the L-shaped fixed plate 103 are fixedly connected to the inclined plates 104. After the lifting platform 2 is lowered, it can be recovered inside the L-shaped fixed plate 103. At this time, the four wheels of the vehicle can be stably placed above the lifting platform 2 through the inclined plates 104, and the top of the fixed column 1 is fixedly connected to the handle frame 3.

[0039] Step S1: First, the vehicle to be repaired is driven inside the fixed column 1 and above the lifting plate 2. Since the lifting plate 2 can be recovered inside the L-shaped fixed plate 103 after being lowered, the four wheels of the vehicle can be stabilized to the top of the lifting plate 2 through the inclined plate 104 and contact the baffle 205 to limit the position;

[0040] Step S2: The hydraulic cylinder 502 extends. Since both ends of the hydraulic cylinder 502 are in rotational cooperation, the hydraulic push is achieved on the diagonal brace 6 of another group after the support, thereby completing the jacking action. Through the cross-rotation action of the diagonal brace 6, the lifting plate 2 can be lifted. During the lifting process, a cross plate 203 is arranged between the lifting plates 2. The cross plate 203 increases the stabilization effect of the two lifting plates 2. During the lifting process of the lifting plate 2, the slider 201 and the first slide groove 101 slide in cooperation to increase stability.

[0041] Step S3: The staff can perform maintenance and disassembly work at the bottom end of the lifting plate 2. When the horizontal plate 203 affects the installation of parts during the disassembly process, the horizontal plate 203 can be slid. Since both ends of the horizontal plate 203 adopt the sliding cooperation of the T-shaped block 2031 and the T-shaped slot 204, the sliding adjustment of the position can be performed as required;

[0042] Step S4: The staff can climb onto the lifting platform 2 through the ladder frame 4 to check the fault problem of the vehicle without repeatedly adjusting the lifting of the lifting platform 2, thereby reducing the lifting operations.
