Description

Technical Field

[0001] The utility model belongs to the field of coal mine production, in particular to a system for protecting a winch wire rope at a right-angle turn of a steeply inclined lane. Background Art

[0002] The mining winch is a single wire rope traction, multi-layer winding winch used for dispatching mine cars and other auxiliary transportation work. The electrical equipment is explosion-proof and suitable for places with coal dust and gas. It is mainly used for traction of mine cars in coal mine loading stations or inclined tunnels, and can also be used for other auxiliary transportation. This type of winch has adjustable working speed and two installation methods: temporary support and foundation installation. It has the characteristics of small size, light weight and easy operation.

[0003] Mining winches are mechanical equipment that use wire ropes wound on drums to pull loads and move. They are mainly used for traction of vehicles underground or on the ground, removal of pillars at coal mining faces, and other auxiliary transportation work. In the daily lifting work of inclined tunnels in mines, it is found that the wire ropes are worn heavily on the side walls of the tunnels at the bends of large-angle inclined tunnels, which not only affects the safety of lifting and transportation, but also affects the service life of the wire ropes due to the large tangential force of the rope guard wheels, resulting in hidden dangers in the lifting and transportation work. Utility Model Content

[0004] The utility model aims to provide a system for protecting winch wire ropes at right-angle turns in steeply inclined lanes, so as to solve the problem of severe wear between the winch wire ropes and the sidewalls of the lanes at right-angle turns in steeply inclined lanes.

[0005] The utility model adopts the following technical scheme: a system for protecting the winch wire rope at a right-angle turn in a steeply inclined lane, comprising a plurality of protection units, each of which is arranged along the direction of the right-angle turn of the lane and arranged at intervals, and each of which is located on the outer side of the turn of the lane;

[0006] Each protection unit includes:

[0007] The protective pole is set vertically, with its lower end extending into the tunnel ground and fixed;

[0008] A fixed diagonal rod is arranged obliquely, one end of which is fixed on the side wall of the tunnel near the outer road, and the other end of which is fixedly connected to the upper end of the protective upright rod to provide support force for the protective upright rod;

[0009] The vertical roller is arranged vertically and parallel to the protective pole. Its upper end is fixed to the upper end of the protective pole, and its lower end is fixed to a position close to the lower end of the protective pole. It is used to intercept the winch wire rope at the bend and prevent the wire rope from rubbing against the side wall of the tunnel, thereby damaging the wire rope.

[0010] Furthermore, each protection unit also includes:

[0011] A horizontal protection rod is horizontally arranged and located above the protection vertical rod, one end of which is fixedly connected to one end of the fixed diagonal rod, and the other end of which extends into the tunnel;

[0012] The horizontal roller is arranged parallel to the horizontal protection rod and is located below the horizontal protection rod. One end of the horizontal roller is fixed to the upper end of the protection vertical rod, and the other end is fixedly connected to the other end of the horizontal protection rod. It is used to intercept the winch wire rope at the turning point and prevent the wire rope from being lifted upward, and keep the wire rope within the area surrounded by the horizontal roller and the vertical roller.

[0013] Furthermore, upper and lower ends of the vertical roller and the horizontal roller are fixed to the corresponding protective upright pole and the horizontal protective pole through two ear plates.

[0014] The beneficial effects of the utility model are:

[0015] The utility model has a high safety factor and is easy to manufacture. It can be manufactured using waste parts, so that the winch wire rope is always in the area surrounded by the horizontal roller and the vertical roller, greatly extending the service life of the wire rope.

[0016] The utility model can reduce deformation in the process of bearing radial force of the wire rope, so that the wire rope can fully contact the horizontal roller and the vertical roller without deviation, is simpler and more practical in use and maintenance, can reduce maintenance costs; and prolongs the service life of the wire rope and reduces the number of maintenance and replacement times.
