[0036] The working principle of the emergency brake of the slider of a waterproof cloth trolley provided by the utility model is as follows: in the operation of laying waterproof cloth on the rock wall of a tunnel, it is necessary to operate through the waterproof cloth operation trolley, and when operating the waterproof cloth trolley, in order to facilitate the braking of the track and the sliding platform inside the trolley, at this time, the inner wall of the track body 1 and the movable plate 2 slide, and the inner rocker plate 412 on the surface of the movable plate 2 is pulled by the chain 3, so that the inner rocker plate 412 drives the outer rocker plate 410 on one side of the movable plate 2, and the outer rocker plate 410 limits the position of the baffle plate 402 with the help of the tensile force of the tension spring 411 on one side of the movable plate 2, so that the baffle plate 402 drives the sliding extrusion rod 403 in the cover frame 401 with the help of the fixed shaft 408 to slide up and down, so that The stop pin 404 fixed at the bottom end of the extrusion rod 403 is plugged into the inlay hole 6 opened in the track body 1 for stop and limit. When the position of the stop pin 404 is moved, the limit column 405 fixed on the inner wall of the movable plate 2 can be used to slide and limit the position of the stop pin 404. Since both ends of the entire baffle 402 are in contact with the outer rocker arm plate 410, no matter which of the two outer rocker arm plates 410 is connected to a chain 3 that breaks, the other outer rocker arm plate 410 can effectively protect the baffle 402 to avoid large displacement after the chain 3 suddenly breaks. At the same time, the position of the baffle 402 is effectively and conveniently deflected, and then the position of the entire stop pin 404 is moved, which is convenient for plugging and braking the inlay hole 6 in the track body 1.

[0037] In the process of using the movable plate 2 to move along the inner wall of the track body 1, in order to facilitate the connection between the stop pin 404 set on the surface of the movable plate 2 and the inlay hole 6 to avoid clogging of the inner wall of the track body 1, the two connecting plates 51 are first fixed to one side of the movable plate 2, and then the limit frame 52 is slid along the sliding column 53 on the surface of the connecting plate 51, and then the roller rotating at the bottom end of the limit frame 52 is moved along the inner wall of the track body 1. At the same time, the scriber 56 at the bottom end of the limit frame 52 can slide along the inner wall of the track body 1 to clean up debris, and the tensile force generated by the second spring 54 on the surface of the sliding column 53 squeezes and limits the limit frame 52, and the protective sheet 57 made of carbide protects the scriber 56. At this time, the clogging of debris between the inlay holes 6 is effectively avoided, thereby preventing the stop pin 404 from being unable to be connected and fixed with the inlay hole 6.
