Embodiment 1

[0023] Embodiment 1, the main body support 1 is fixed on the side wall of the rope outlet of the mine hoist with expansion bolts, and one end of the steel wire rope 6 with a diameter of 8 mm is fixed at the upper end connection of the counterweight 4. After passing through the pulley 2, the steel wire rope 6 pieces Tighten and fix the other end to the opposite wall. The counterweight 4 can slide longitudinally along the guide rail 3 . The normally open proximity switch 5 is a metal induction normally open switch. When there is metal close to its end, the normally open point is closed, and when no metal is close, the normally open point is disconnected. The corresponding frequency is 100 times / second. When the hoist main rope 7 was slack, the hoist main rope 7 hung down on the steel wire rope 6, and the counterweight 4 was lifted by the steel wire rope 6. Counterweight 4 is a metal material and adopts a cast iron structure. When counterweight 4 rises along guide rail 2 and its...

Abstract

The invention discloses a mine hoist rope looseness detecting device. The mine hoist rope looseness detecting device comprises a main body bracket and a steel wire rope; a pulley is fixedly connected to the upper end of the main body bracket, and a guide rail is fixedly connected to the lower end; a counterweight block is arranged on the guide rail, and slides on the guide rail; a normally open proximity switch is fixedly connected to the side edge of the main body bracket, is positioned beside the guide rail, and is matched with the counterweight block; the counterweight block is fixedly connected to one end of the steel wire rope; and the other end of the steel wire rope penetrates through the pulley, and extends for fixation. The rope looseness detecting device with the structure is stable, reliable and not easy to damage; as the non-contact proximity switch is adopted, actions are sensitive, no wear is generated, and meanwhile, such problems as failure caused by rusting cannot occur; through use of the normally open proximity switch, the corresponding speed is higher; and through the height adjustment of the normally open proximity switch, the rope looseness detecting sensitivity can be adjusted.

Description

technical field [0001] The invention relates to the field of hoist protection, in particular to a detection device capable of detecting the slack state of a steel wire rope of a mine hoist. Background technique [0002] During the operation of the mine hoist, there may be accidents such as tank jamming, road drop, and over-discharging. If the hoist control system cannot detect this state in time, the hoist will be stopped in time. When the accident expands, it may cause broken ropes and tanks falling serious safety accidents. At present, the occurrence of the appeal fault is judged by detecting whether the wire rope of the hoist is slack. Timely and reliable detection of appeal accidents can avoid further amplification of accidents. [0003] The main method of the current slack rope protection detection device is: use a mechanical travel switch to realize it, that is, a mechanical travel switch is fixed on the wall of the rope exit of the hoist or the wall in the pit under...
