Elevator traction wheel slipping amount detecting device and method

Abstract

The invention discloses an elevator traction wheel slipping amount detecting device and method. The device comprises an elevator traction system, an image acquiring device, a wireless transmission device and a monitoring center; the elevator traction system comprises a traction wheel, a traction wheel motor, a steel wire rope with a scale mark and a control cabinet; the traction wheel motor is electrically connected with the traction wheel; the steel wire rope is placed in a rope groove of the traction wheel; the steel wire rope is matched with the rope groove of the traction wheel; the control cabinet is electrically connected with the traction wheel motor; the control cabinet is used for reading the revolution of the traction wheel motor; the image acquiring device is arranged above the traction wheel; the image acquiring device is used for acquiring a scale mark image of the steel wire rope; the wireless transmission device is connected with the image acquiring device and the control cabinet; and the wireless transmission device is used for transmitting the scale mark image acquired by the image acquiring device and the revolution of the traction wheel motor to the monitoring center. The device and method solve the problem that elevator maintaining personnel have danger in the measuring process.

Description

technical field [0001] The invention relates to the technical field of elevator safety detection, in particular to an elevator traction sheave slip detection device and method. Background technique [0002] The elevator traction machine is used as the driving mechanism. The steel wire rope is hung on the sheave of the traction machine, and the car is suspended at one end, and the counterweight is suspended at the other end. When the traction machine rotates, the friction between the traction sheave and the wire rope generates traction force to drive the car to move up and down. When the car is rising or falling, due to the unbalanced force on both ends of the wire rope, a certain elastic stretch will occur, and the slippage between the traction sheave and the wire rope is normal slippage. However, during the long-term use of the elevator, due to the wear and tear between the traction sheave and the wire rope, a certain amount of slippage will occur between the traction shea...
