Problems solved by technology

[0003] The existing detection device installs the rotary encoder directly on the wire rope to measure the distance traveled by the wire rope. Because the surface of the wire rope is rough and wears a lot, using the rotary encoder to directly contact the wire rope to detect slippage is not conducive to long-term and all-weather use. to detect slippage

Abstract

The invention discloses an elevator traction wheel sliding detection device and method. The elevator traction wheel sliding detection device comprises a traction wheel angular displacement measuring device, a speed limiter angular displacement measuring device and a signal processing system, wherein the traction wheel angular displacement measuring device and the speed limiter angular displacementmeasuring device are electrically connected with the signal processing system, the traction wheel angular displacement measuring device is fixedly connected to an elevator frame, and the traction wheel angular displacement measuring device, the speed limiter angular displacement measuring device and the signal processing system are all arranged on an iron plate at the top of an elevator machine room. The traction wheel angular displacement measuring device and the speed limiter angular displacement measuring device are used to calculate the slippage amount between a traction wheel and a steelwire rope, and the measurement belongs to non-contact measurement so that the defect of direct contact measurement can be overcome; and long-time and all-weather automatic detection of the slippage amount can be realized conveniently, and a scientific basis is provided for scientifically judging whether the traction wheel loses efficacy or not.

Description

technical field [0001] The invention relates to the technical field of elevator detection, in particular to an elevator traction sheave slip detection device and a detection method thereof. Background technique [0002] The elevator traction motor drives the traction wheel to rotate, and drives the steel wire rope to drag the car and the counterweight device for relative movement, so that the car performs the vertical lifting task of the elevator along the guide rail in the hoistway. Due to the friction and wear between the traction sheave and the wire rope, abnormal slippage occurs between the traction sheave and the wire rope. The failure form of the traction sheave is mainly manifested in the excessive slip between the traction sheave and the wire rope. If there is too much slip between the wire rope and the traction sheave during the normal operation of the elevator, it will affect the transmission efficiency and safety of the elevator, and may cause the car to fall, ca...
