[0025] Among them, the hydraulic drive seat 8 is used to connect the first hydraulic cylinder 4 and the second hydraulic cylinder 5 and provide power for the hydraulic cylinders. The lifting parts 6 are used to lift the automobile parts to be repaired. The auxiliary fasteners 7 are used to stabilize the automobile parts to prevent them from shaking during maintenance.

[0026] The hanging member 6 comprises a base 61 , a chain 62 is arranged at the lower end of the base 61 , and a hook 63 is hung at the end of the chain 62 .

[0027] When the first hydraulic cylinder 4 is working, one end of the top frame 3 is driven to deflect relative to the vertical frame 2, and the top frame 3 drives the second hydraulic cylinder 5, and the second hydraulic cylinder 5 drives the hanging piece 6 and the auxiliary fastener 7 at one end thereof to deflect synchronously. By controlling the telescopic stroke of the first hydraulic cylinder 4, the deflection direction and deflection angle of the hanging piece 6 and the auxiliary fastener 7 are flexibly adjusted;

[0028] When the hoisting member 6 deflects downward, the end hook 63 moves downward, and when the hoisting member 6 deflects upward, the end hook 63 moves upward, thereby adjusting the height position of the end hook 63. When hoisting automobile parts, the hook 63 is fixed to the automobile parts, and then the telescopic stroke of the first hydraulic cylinder 4 is controlled to lift the automobile parts through the hook 63 to achieve hoisting.

[0029] When the second hydraulic cylinder 5 is working, it drives the hanging member 6 at one end thereof to adjust the horizontal position of the hanging member 6 . When automobile parts are hung on the hook 63 , the horizontal position of the automobile parts is adjusted by the second hydraulic cylinder 5 .

[0030] The two groups of side seats 71 are respectively welded and fixed on both sides of the base 61 , a rotating shaft 73 is welded and fixed on the adjustment seat 72 , and the rotating shaft 73 is rotationally connected to the side seat 71 , and the rotating shaft 73 and the side seat 71 are fixed by a first fastener 74 .

[0031] Among them, by loosening the first fastener 74, the rotating shaft 73 of the adjustment seat 72 can rotate relative to the side seat 71. At this time, the rotation direction and rotation angle of the limit rod 77 relative to the side seat 71 can be adjusted. After the adjustment is completed, tighten the first fastener 74.

[0032] The adjusting block 75 and the adjusting seat 72 are rotatably connected via a rotating shaft, and the adjusting block 75 and the adjusting seat 72 are fixed via a second fastener 76 .

[0033] Among them, by loosening the second fastener 76, the adjustment block 75 can rotate relative to the adjustment seat 72. At this time, the rotation direction and rotation angle of the limit rod 77 relative to the adjustment seat 72 can be adjusted. After the adjustment is completed, the second fastener 76 is tightened.

[0034] Among them, the first fastener 74 and the second fastener 76 both include a handle 761 and a stud 762, and the first fastener 74 is threadedly connected to the side seat 71, and the second fastener 76 is threadedly connected to the adjustment seat 72. The loosening and locking methods of the first fastener 74 and the second fastener 76 are simple, and only a certain external force needs to be applied to rotate the handle 761 of the first fastener 74 and the second fastener 76.

[0035] The limiting rod 77 includes a sleeve 771 and a telescopic rod 772 . One end of the telescopic rod 772 is slidably embedded in the sleeve 771 . The sleeve 771 and the telescopic rod 772 are fixed by a tightening screw 773 .

[0036] Among them, loosen the tightening screw 773, then the telescopic rod 772 can slide relative to the sleeve 771, the extension length of the telescopic rod 772 can be adjusted, and then the total length of the limit rod 77 can be adjusted. After the adjustment is completed, tighten the tightening screw 773 to tighten it.

[0037] The angle position and length of the limit rods 77 on both sides of the auxiliary fastener 7 can be flexibly adjusted and stabilized. When the automobile parts to be repaired are hung on the hook 63, the limit rods 77 on both sides can be adjusted, and the automobile parts can be locked by two sets of limit rods 77 to prevent them from shaking, thereby improving the stability of the automobile parts when they are suspended for repair.

[0038] When the auxiliary fastener 7 is not used, as Figure 4 As shown, the auxiliary fastener 7 is folded on one side without affecting the normal lifting operation of the lifting member 6.

[0039] Among them, the tail end of the first hydraulic cylinder 4 is rotatably connected to the vertical frame 2 through a rotating shaft, one end of the push rod of the first hydraulic cylinder 4 is rotatably connected to the top frame 3 through a rotating shaft, and one end of the top frame 3 is rotatably connected to the vertical frame 2 through a rotating shaft.

[0040] When the first hydraulic cylinder 4 is working, its push rod pushes the top frame 3, causing the top frame 3 to deflect relative to the vertical frame 2. At the same time, one end of the push rod of the first hydraulic cylinder 4 is adaptively deflected relative to the top frame 3, and the end of the first hydraulic cylinder 4 is adaptively deflected relative to the vertical frame 2.

[0041] The hydraulic drive seat 8 includes a hydraulic pump assembly, a valve assembly, an oil tank and an oil pipe. The first hydraulic cylinder 4 and the second hydraulic cylinder 5 are connected through the hydraulic drive seat 8 and provide power for the first hydraulic cylinder 4 and the second hydraulic cylinder 5.

The setting of the rollers 11 facilitates the movement of the overall lifting frame, and can move the lifting frame to a designated working area. After lifting, the overall lifting frame remains stable under the action of the gravity of the automobile parts.

[0043] Working principle: Move the lifting frame to the designated working area, the first hydraulic cylinder 4 works, driving one end of the top frame 3 to deflect relative to the vertical frame 2, the top frame 3 drives the second hydraulic cylinder 5, the second hydraulic cylinder 5 drives the lifting part 6 and the auxiliary fastener 7 at one end thereof to deflect synchronously, by controlling the telescopic stroke of the first hydraulic cylinder 4, the deflection direction and deflection angle of the lifting part 6 and the auxiliary fastener 7 are flexibly adjusted, the lifting part 6 deflects downward, the end hook 63 moves downward, the hook 63 is fixed to the automobile parts, the lifting part 6 is driven to deflect upward by the first hydraulic cylinder 4, and the lifting part 6 is driven linearly by the second hydraulic cylinder 5 to lift the automobile parts to the designated height. When the auxiliary fastener 7 is not used, the auxiliary fastener Part 7 is folded on one side, which does not affect the normal lifting operation of the lifting part 6. When using the auxiliary fastener 7, loosen the first fastener 74 and adjust the rotation direction and rotation angle of the limit rod 77 relative to the side seat 71. After the adjustment is completed, tighten the first fastener 74 to tighten it, loosen the second fastener 76, and adjust the rotation direction and rotation angle of the limit rod 77 relative to the adjustment seat 72. After the adjustment is completed, tighten the second fastener 76 to tighten it, loosen the tightening screw 773, and adjust the extension length of the telescopic rod 772. After the adjustment is completed, tighten the tightening screw 773 to tighten it, adjust the limit rods 77 on both sides, and lock the automobile parts through two sets of limit rods 77 to prevent the automobile parts from shaking, which is convenient for maintenance.
