Abstract

The invention discloses a real-time monitoring device and method for the comprehensive gear abrasion condition of a winch hoist. The device comprises an electric motor, wherein the motor is connectedwith a gearwheel at a drum shaft end through a speed reducer and a pinion; a motor angular speed rotation coding sensor is arranged at a motor rotating shaft end; a motor vibration sensor is also arranged on the motor; a drum shaft end vibration sensor is arranged at the drum shaft end; a drum shaft end follow-up cable system component is arranged at the lower portion of the drum shaft end; and the motor, the motor angular speed rotation coding sensor, the motor vibration sensor and the drum shaft end vibration sensor are all connected with a controller. The comprehensive gear abrasion condition of the winch hoist can be obtained in real time in an on-line mode, early warning can be conducted on the running safety condition of the hoist in advance, and operation and maintenance personnel can be guided to conduct predictive maintenance.

Description

technical field [0001] The invention relates to the technical field of hoist in water conservancy and hydropower projects, in particular to a real-time monitoring device for hoist-type hoist, and also to a real-time monitoring method for the hoist. Background technique [0002] Hoist hoist is an important permanent equipment in water conservancy and hydropower projects, and its own operation safety directly affects the safety of reservoir dams. Since the hoist hoist is a heavy-duty operating equipment, the wear of its gear transmission system is relatively serious, especially in the western region and the Hetao Plain where the wind and sand are relatively large. [0003] At present, there is no real-time online method to obtain the comprehensive gear wear status of the winch hoist in real time, let alone realize the early warning of the operation safety status of the winch hoist and guide the operation and maintenance personnel to perform predictive maintenance.
