Control device capable of preventing elevator deceleration

Abstract

The invention discloses a control device capable of preventing elevator deceleration. The control device comprises an elevator shaft; a car is movably connected to the surface of the inner wall of theelevator shaft; a steel strand is fixedly connected to the top of the car; a top plate is fixedly connected to the surface of the inner wall of the elevator shaft and positioned at the top of the car; the left side of the top of the top plate is connected with a control box through a bolt; the top of the top plate is rotationally connected with a first transmission wheel; a motor is fixedly mounted on the back surface of the first transmission wheel; a second transmission wheel is rotationally connected to the top of the top plate and positioned on the right side of the first transmission wheel; and the steel strand is movably connected to the surfaces of the first transmission wheel and the second transmission wheel. Through cooperation of an electric extension rod, a limiting block, a photoelectric speed sensor, a chute, a spring, a linear speed sensor, a damping plate and a damping spring, the problem of incapability of guaranteeing the life safety of users under emergencies due toa certain potential safety hazards in a traditional elevator is solved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a control device for preventing rapid descent of an elevator. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings...
