Tail rope twisting detection device of lifting machine

Abstract

The invention relates to a tail rope twisting detection device of a lifting machine and particularly relates to underground mining operations. The tail rope twisting detection device of the lifting machine comprises two detection boxes, a detection fiber, a signal fiber and a light transmitting and receiving device, wherein the detection fiber is fixed on an isolation sleeper; during operation, a light-emitting diode emits light; the light is transmitted into the detection fiber through the signal fiber; the light finally enters a photosensitive diode; a light signal processing circuit is used for determining that the isolation sleeper operates normally so long as signals from the photosensitive diode are received when the light-emitting diode emits light operates; once the photosensitive diode does not receive the light signals, the light signal processing circuit outputs fault signals instantly and determines that the isolation sleeper is abraded or the tail rope twisting fault occurs. The tail rope twisting detection device of the lifting machine is high in adaptability to environment, ingenious in mounting position design, accurate in detection and low in manufacturing cost.

Description

technical field [0001] The invention relates to a hoist tail rope kink detection device, especially related to underground mining operations. Background technique [0002] In the multi-rope lifting system, the balance tail rope is an important part, but when the tail rope is raised and lowered, it will generate axial force and radial deflection, which will cause the tail rope to rotate. The underground environment is harsh, and the tail rope rotating device at the bottom of the hoisting container is prone to failure, which will also lead to increased tension on the tail rope and kinking. The use of the balance tail rope is directly related to the operation of the hoist and the normal production of the mine. When the tail rope of the hoist is kinked, if the hoist cannot be stopped in time, the resulting economic losses range from tens of thousands to tens of millions. , and when dealing with tail rope kink faults, they all work at high altitude in the wellbore. It takes a fe...
