Embodiment Construction

[0020] Below in conjunction with accompanying drawing, structure and principle of the present invention are described in detail:

[0021] A kink detection device for the tail rope of a hoisting machine, such as figure 1 As shown, two detection boxes 1, detection optical fibers 9, signal optical fibers 10 and optical transceivers are included, the detection optical fibers 9 are fixed on the isolation sleepers, and the detection boxes 1 are fixed on the steel beams of the fixed isolation sleepers and are located at both ends of the isolation sleepers, Both ends of the detection fiber 9 are respectively connected to the signal fiber 10 in the detection box 1 , and the signal fiber 10 is connected to the optical transceiver. The detection box 1 is provided with a first track 2, a second track 3, a first slider 5 and a second slider 4 that are respectively arranged on the two tracks and can slide along them, and a pushing device. The first track 2 is a straight line. Row track, th...

Abstract

The invention relates to a kink detection device for a tail rope of a hoisting machine, especially related to underground mining operations. The kink detection device for the tail rope of the hoisting machine according to the present invention includes two detection boxes, detection optical fibers, signal optical fibers and optical transceivers. Optical fiber, finally the light enters the photodiode. When the light-emitting diode is working, the optical signal processing circuit considers that the isolation sleeper is working normally as long as it receives the signal from the photodiode. Once the photodiode does not receive the light signal, the optical signal processing circuit board outputs the output. A fault signal, it is believed that the isolation wood is worn or a tail rope kink fault has occurred. The hoist tail rope kink detection device of the present invention has high environmental adaptability, ingenious installation position design, accurate detection and low manufacturing cost.

Description

technical field [0001] The invention relates to a kink detection device for a tail rope of a hoisting machine, especially related to underground mining operations. Background technique [0002] In the multi-rope hoisting system, the balance tail rope is an important part, but when the tail rope is raised and lowered, axial force and radial deflection will be generated, 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 cause the tail rope to bear more tension and kink. 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 economic loss caused by the hoist is as little as tens of thousands to tens of millions. , and when dealing with the kink fault of the tail rope, it is all wellbore ...
