Construction hoist emergency self-rescue equipment for engineering construction

The construction hoist emergency self-rescue equipment for engineering construction comprises a hoist body, a hoist cavity is formed in the hoist body, and a cover plate and a safety rope are arranged in the hoist cavity; a guide sliding rail is slidably connected in the elevator body and located on the left side of the elevator cavity, the upper end of the guide sliding rail extends upwards and penetrates through a pressurizing cavity formed in the left end of the cover plate, and pressurizing plates capable of sliding left and right are symmetrically arranged on the left side and the right side in the pressurizing cavity. A balance block cavity is formed in the right end in the elevator body, and a balance block capable of sliding up and down is arranged in the balance block cavity. The falling state of the elevator body is detected through the balance block, then the safety rope is driven to fall downwards into the elevator cavity to be fixedly connected with a trapped person, then the fixing block is driv
