Abstract

The invention discloses an electric push rod type elevator car accidental movement stop device, which comprises U-shaped fixing seats respectively installed at the two ends of the upper beam of the elevator car, and the two ends are inserted through two U-shaped fixing seats respectively. The electric push rod and the controller used to control the action of the electric push rod, the controller is connected with the control system of the elevator car, the middle part of the electric push rod is suspended, and the leveling area of ​​each layer of the elevator guide rail corresponds to the end of the electric push rod The positions are respectively provided with a stop plate, and a stop hole matching with the end of the electric push rod is provided on the stop plate. The two side walls of the U-shaped fixed seat are extended and retracted. The position of the shell end of the electric push rod corresponding to the U-shaped fixed seat on the same side is also respectively provided with the two side walls of the U-shaped fixed seat. Offset extension limit plate and retraction limit plate. Suitable for elevators.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an electric push rod type elevator car accidental movement stop device. Background technique [0002] In recent years, safety accidents about elevators have been reported frequently, making people pay more attention to elevator safety. For example, recently there have been shearing accidents caused by sudden movement of the elevator car when the door of the elevator car is open. When the elevator car door is in the open state, theoretically the elevator car should not be lifted or lowered, but in practice, due to various reasons, this kind of shearing accident may occur, which poses a potential hazard to the people in the elevator car. security risks. Therefore, it is necessary to design a stop device that can avoid the accidental lifting and moving of the elevator car for the above situation, so as to improve the safety of the elevator. Contents of the invention [0003] The purpose...
