Monitoring device and method for rope regulating state of deep-well lifting equipment

Abstract

The invention discloses a monitoring device and method for the rope regulating state of deep-well lifting equipment. The whole system comprises micro fluid-flow power generators, synchronous pulleys, encoders, a communicating vessel, electromagnetic speed regulating valves, connecting plates and an acquiring device which are all mounted at the positions of tension balancing devices; electric energy can be generated by utilizing the flow of hydraulic oil of a rope regulating device, thereby supplying power to the monitoring device; the rope regulating speed can be controlled by regulating the openings of the electromagnetic speed regulating valves; the encoders can be driven by the synchronous pulleys to effectively measure the rope regulating state; and a digital-quantity acquiring and transmitting method is adopted for the monitoring device, so that the interference to wireless transmission can be reduced to the great extent. The monitoring device is compact in structure; a simple and convenient detecting method is adopted; no manual maintenance is needed; the reliability is high; the abnormal running state of the rope regulating device can be effectively monitored and controlled visually and correctly; and the occurrence of a steel wire rope breaking accident can be effectively avoided.

Description

technical field [0001] The invention relates to a monitoring device and method for a rope adjustment state, in particular to a monitoring device and method for a rope adjustment state suitable for deep well hoisting equipment. Background technique [0002] Known as the "throat of the mine", the hoist plays an important role in lifting coal gangue and lifting personnel equipment, and is the link connecting the mine's underground production system and the ground industrial square. With the increase of mining depth, the self-weight of the hoisting wire rope increases sharply, and single-rope hoisting equipment can no longer meet the requirements of deep well hoisting. In this case, multi-rope hoisting equipment has become the first choice for deep well mining. But at the same time, multi-rope hoisting also brings about the problem of inconsistent effective rope lengths, which brings hidden dangers to the safe and stable operation of deep well hoisting equipment. According to t...

Problems solved by technology

[0003] However, in daily use, the tension balance device has problems such as jumping the rope and short adjustment stroke. If the state of the rope adjustment cannot be monitored and managed in real time, and the extension of the balance device can be adjusted in time, once a failure occurs, the lifting safety and the use of the wire rope will be damaged. Life is seriously threatened
