Coiling spring elevator rescue device

Abstract

The invention relates to a coiling spring elevator rescue device, which consists of a top base, a coiling spring, a hanger frame and a shaft pin. The coiling spring elevator rescue device is characterized in that the top base is fastened at the top end of a lifting box by bolts, the top base and the hanger frame are integrally designed, the coiling spring is arranged in a hanger frame bin, one end of the coiling spring is combined with the hanger frame through the shaft pin, and the other end of the coiling spring is connected with a pull ring. When people take an elevator, the pull ring is held by one handle of people. When the elevator descends at a high speed because of faults, the pull ring can be directly used by people to enable feet to leave a base plate of the lifting box, and the weight of the people can be entirely transferred to the coiling spring. When the lifting box touches the ground, the weight of the human body is superposed with instantaneous weight generated by the inertia speed to draw the coiling spring downwards, and then, the spring resets to transfer the hard force to the coiling spring so as to realize the function of protecting staffs in the high-speed descending process of the elevator.

Description

Technical field [0001] The invention relates to an elevator safety protection device, in particular to a coil spring elevator rescue device. Background technique [0002] Elevators have become a necessary facility for high-rise buildings, but the hidden dangers of elevators have not been completely solved, especially when the elevators fail at a high speed, which poses a serious threat to the lives of passengers. Summary of the invention [0003] The purpose of the present invention is to provide a coil spring elevator rescue device, which effectively solves the protective effect of personnel during the high-speed descent of the elevator when the elevator fails. [0004] The invention is realized by the following technical scheme: a coil spring elevator rescue device, which is composed of a top seat, a coil spring, a hanger, and an axle pin. It is characterized in that the top seat is fastened to the top of the lifting box by screws, the top seat and the hanger are integrated desi...
