Research on a mechanical device to prevent people from being squeezed in elevator pit

Service elevators are widely used in restaurants, shopping malls, canteens and other places. With the development of Commerce, the number is increasing day by day. In order to ensure the normal operation of the utility elevator, the maintenance of the utility elevator is particularly important. The pit of the service elevator is generally small in area and shallow in depth. When repairing the elevator parts in the pit, due to the small space, the maintenance personnel are particularly vulnerable in the narrow space. It often happens that the head accidentally touches the bottom of the car when standing up, or the car accidentally moves or falls and squeezes the maintenance personnel. Therefore, it is very necessary to install a mechanical device to prevent personnel from being squeezed in the sundry elevator pit to ensure the safety of maintenance personnel. This paper studies a mechanical device, which can effectively solve this kind of problem, and is convenient and reliable.
