Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the utility model, fall within the scope of protection of the utility model.

Embodiments of the utility model:

as shown in fig. 1 to 4, a guide rail for a cargo elevator with an auxiliary braking function comprises a guide rail 1, a brake column 2 and a hinge rod 3.

The guide rail 1 is vertically arranged, and a brake groove 10 for being matched with the brake column 2 is formed in the guide rail 1; the left and right spaces of the brake column 2 are provided with two; the brake column 2 penetrates through the side wall of the loading shelf 8 in a sliding manner, one end of the brake column 2 is positioned in the brake groove 10, and the other end of the brake column is hinged with one end of the hinge rod 3; the two hinging rods 3 are arranged in total, one ends of the two hinging rods 3 are mutually hinged, and the other ends of the two hinging rods are respectively hinged with the two braking columns 2; the carrier 8 is provided with a pulling rod 5 for driving the hinging rod 3 to abut against the brake column 2 to contact the brake groove 10; when the pulling rod 5 is pulled, the pulling rod 5 drives the two hinging rods 3 to act, so that the two ends of the two hinging rods 3 are respectively abutted leftwards and rightwards, thereby causing the brake posts 2 to respectively move leftwards and rightwards to be abutted with the brake grooves 10, and braking is realized.

Two groups of guide rails 1 are arranged at left and right intervals; the opening of the brake groove 10 is arranged oppositely; in this embodiment, two sets of guide rails 1 are disposed at left and right intervals, and the two sets of guide rails 1 are located at two corners of the rear side of the carrier 8, where the braking slot 10 on each guide rail 1 is disposed toward the middle of the left and right directions, that is, the openings are disposed opposite to each other.

The carrier 8 comprises sliding sleeves 80, two sliding sleeves 80 are arranged at intervals corresponding to the left and right braking columns 2, and the two braking columns 2 are respectively arranged in the two sliding sleeves 80 in a sliding mode.

The end of the brake column 2 facing the brake groove 10 is provided with a brake circular table 20, and the diameter of the brake circular table 20 is larger than the inner diameter of the sliding sleeve 80, so that the brake column 2 can be prevented from being separated from the sliding sleeve 80.

The left end of the hinging rod 3 at the left end is hinged with the left brake column 2, and the right end of the hinging rod 3 at the right end is hinged with the right brake column 2; the two hinging rods 3 are hinged by a fixing pin 4; the right end of the left hinging rod 3 is hinged with the left end of the right hinging rod 3, and the fixed pin 4 is rotatably arranged at the hinging position of the two hinging rods 3; the carrying shelf 8 is provided with a fixing plate 81, the fixing plate 81 is positioned at the front sides of the two sliding sleeves 80, the fixing plate 81 is transversely arranged, and the left end and the right end of the fixing plate 81 are respectively fixed on the left side wall and the right side wall of the carrying shelf 8; the fixed plate 81 is provided with a connecting rod 6 in a sliding way back and forth, the rear end of the connecting rod 6 is positioned at the rear side of the fixed plate 81 and is connected with the fixed pin 4, the front end of the connecting rod 6 is positioned at the front side of the fixed plate 81 and is connected with the pulling rod 5, and the length direction of the pulling rod 5 is arranged along the left-right direction; the connecting rod 6 is sleeved with a spring 7, the rear end of the spring 7 is abutted against the fixed pin 4, and the front end of the spring 7 is abutted against the rear side of the fixed plate 81; when the carrier 8 normally operates, under the action of the spring 7, the fixing pin 4 moves backwards, the two hinging rods 3 are in an inclined state, namely the hinging positions of the two hinging rods 3 are relatively back, at the moment, the two braking posts 2 are pulled out towards the middle by the hinging rods 3, when braking is needed, the pulling rod 5 is pulled forwards, the fixing pin 4 moves forwards under the action of the connecting rod 6, the two hinging rods 3 tend to be collinear, and the two hinging rods are abutted to the braking posts 2 to move towards the inside of the braking groove 10 respectively, so that the braking round platforms 20 are in contact with the braking groove 10, friction is generated, and the upward and downward movement of the carrier 8 is assisted.
