Detailed Description

The present invention will be further described with reference to fig. 1 to 4.

The automobile maintenance lifting device with the safety brake function comprises upright columns 1 symmetrically distributed on two sides, wherein each upright column 1 is hollow and columnar, and a screw rod 15 is rotatably connected in the inner cavity of each upright column. The outer side of the upright post 1 is connected with a motor 16, and the screw rod 15 is driven by the motor 16. The screw rod 15 is connected with lifts the arm 2, it is connected with nut 17 to lift the arm 2, thereby nut 17 is connected with the screw rod 15 cooperation makes and lifts the arm and slide from top to bottom along stand 1. A brake groove 3 is connected to the inner cavity of the upright post 1, one side of the lifting arm 2 extends into the upright post 1 and is connected with a brake wheel 4, and the brake wheel 4 extends into the brake groove 3; two side wall plates 5 of the brake groove 3 can move relatively to change the groove width of the brake groove 3, and the brake wheel 4 can be connected with the two side wall plates 5 of the brake groove 3 in a pressing mode. When the lifting arm 2 needs to be lifted up and down, the two side wall plates 5 are opened to enable the groove width of the brake groove 3 to be larger than the diameter of the brake wheel 4, so that the brake wheel can be freely lifted up and down; when the lifting arm 2 is at the corresponding height, the groove width of the bottom of the braking groove 3 is adjusted to enable the groove width of the bottom of the braking groove 3 to be smaller than the diameter of the braking wheel 4, so that the braking wheel and the braking groove are prevented from being extruded relatively to form braking when the lifting arm is lowered accidentally.

Specifically, the brake groove 3 includes a bottom plate 6 and two side wall plates 5, the top of the side wall plate 5 is rotatably connected with the bottom plate through a connecting pin, the upright post 1 is connected with an ejector rod 7 through a thread, and the ejector rod 7 extends into the upright post 1 and is connected with the side wall plates 5 in a jacking manner.
