Description

Technical Field

[0001] The utility model relates to the technical field of underground coal mine machinery, in particular to an underground coal mine chute cable supporting device. Background Art

[0002] The underground drift of a coal mine is a tunnel for people and coal mining equipment to enter and exit. The coal mining equipment is powered by cables, which travel through the drift and connect to the coal mining equipment. In most cases, the cables are directly dragged on the ground of the drift during the movement of the coal mining equipment. The cables are damaged by long-term friction with the ground, which reduces the service life of the cables.

[0003] The invention patent with application number 202010013057.0 discloses an automatic cable storage device for mining chute tunnels, including a first cable storage vehicle, a middle cable storage vehicle, a rear cable storage vehicle, an automatic telescopic connection device, a cable carrying device and an auxiliary power system. The first cable storage vehicle is connected to the rear of the equipment train in the front, and the vehicle body of the equipment train carries an auxiliary power system. The auxiliary power system includes an electric winch and a steel wire rope. Several middle cable storage vehicles are connected to each other through two sets of left and right automatic telescopic connection devices. The middle cable storage vehicle is connected to the rear cable storage vehicle, and the rear cable storage vehicle is provided with a connection mechanism for connecting to a rear transfer machine or an advance bracket. The automatic storage device is adopted to avoid long-term friction and wear between the cable and the ground, thereby improving the service life of the cable.

[0004] Because the equipment train, transfer machine, bracket, and cable cannot move together with the storage vehicle, the equipment train, transfer machine, and bracket move one after another, the length of several storage vehicles expands and contracts periodically, and the cable is relatively fixed to the storage vehicle, so the cable bends and stretches repeatedly, causing damage. Summary of the invention

A type of advanced hydraulic bracket 30 with a rotatable self-resetting top beam as disclosed in the application number 201811061948.2 of the applicant can be used. The guide rail 20 extends in a straight line along the direction in which the bracket 30 moves in the coal mine shaft chute 10. It is preferable that the guide rails 20 of each bracket 30 are collinear in the coal mine shaft chute 10. It is preferable that the guide rail 20 forms a small angle with the horizontal plane. The rolling part 40 moves from one end of the guide rail 20 to the other end under the action of gravity. The direction in which the rolling part 40 moves under the action of gravity is the direction in which the bracket 30 moves.
