Stepper cable holding car and fully-mechanized mining surface stepper cable management system using same

Abstract

The invention proposes a stepper cable holding car. The stepper cable holding car comprises guide rails, a front cable holding car and a rear cable holding car, wherein a push-pull cylinder is connected between the front cable holding car and the rear cable holding car; the cable holding cars comprise shells and wedge-shaped clamping devices; the shells are provided with cable holding tanks and front wheels and back wheels for walking on the guide rails; the wedge-shaped clamping devices comprise clamping cylinders; the clamping cylinders have two piston rods arranged in opposite directions; the piston rods are fixedly provided with wedge-shaped mechanisms; tension spring mechanisms are connected between the two wedge-shaped mechanisms; the wedge-shaped mechanisms have wedge-shaped clamping parts; the wedge-shaped clamping parts of one wedge-shaped mechanism are clamped at the front sides of the positions in contact with the guide rails below the front wheels; the wedge-shaped clamping parts of the other wedge-shaped mechanism are clamped at the back sides of the positions in contact with the guide rails below the back wheels; and the push-pull cylinder and the clamping cylinders are connected with a control device. The invention further discloses a fully-mechanized mining surface stepper cable management system. The stepper cable holding car is simple in structure, and adapts to movement in upslope and downslope directions.

Description

technical field [0001] The invention relates to the technical field of a step-by-step cable management system for a fully-mechanized mining face, in particular to a step-by-step cable car and a step-by-step cable management system for a fully-mechanized mining face using the same. Background technique [0002] Due to the large power and tonnage of fully mechanized mining equipment and the high flow requirements of waterways and fluids, it is necessary to be equipped with large-diameter, large-capacity, large-number power supply cables, water supply and liquid supply pipelines, and the transportation from the mobile equipment train to the working face. There are 13 kinds of cables, water and liquid circuits, control lines and signal lines. With the displacement of the machine, the cable must also move. For example, when the coal mining machine is mining coal, its electric energy is transmitted through the cable. Advance forward, and the power cable must be dragged along unti...
