Device for catching hoisting steel rope with force-sensing manipulator to protect hoisting steel rope against slipping

Abstract

The invention discloses a device for catching a hoisting steel rope with force-sensing manipulators to protect the hoisting steel rope against slipping, which belongs to the mine equipment and is used for the vertical shaft hoisting system. The device comprises a stand (7), a plurality of force-sensing manipulators (2) and a stepping motor (3) for driving the force-sensing manipulators (2) to move. The stand (7) is a rectangular steel structure frame; one side of the stand (7) is a detachable movable beam (9); a force-sensing manipulator mounting beam (10) and a blocking beam (8) which can move in the stand (7) are transversely arranged in the inner cavity of the stand (7), and the force-sensing manipulator mounting beam (10) and the blocking beam (8) are connected with the stepping motor(3) by synchronous screws; the stepping motor (3) is arranged outside the stand (7); and the force-sensing manipulators (2) are arranged on the force-sensing manipulator mounting beam (10). The device can be used for automatically detecting the hoisting steel rope on line and rapidly braking the hoisting steel rope by applying variable force through the programmable logic control (PLC). The device can be controlled remotely and installed conveniently and safely.

Description

technical field [0001] The invention relates to a mine equipment, in particular to an automatic protection equipment used in the shaft hoisting system of a coal mine and a non-coal mine when a slipping rope occurs. Background technique [0002] Mine vertical shaft hoisting devices generally use multiple wire ropes of endless rope winches to lift, and the movement of the wire ropes is driven by friction wheels driven by motors. Once the steel wire rope slips and slides, the hoist will fail to work at least, resulting in a stoppage of production, and at worst, the car will slide, and the cage will fall rapidly, causing a safety accident. At present, the domestic research on the sliding rope car only stays in the monitoring of the sliding rope car. When the rope sliding car occurs in the hoist, it can only be braked by the parking brake, and the moving steel wire rope and the hoisting car cannot be controlled. The container stops, so that the serious accident of sliding rope s...

Once the steel wire rope slips and slides, the hoist will fail to work at least, resulting in production stoppage; at worst, the car will slide, and the cage will fall rapidly, causing a safety accident

At present, the domestic research on the sliding rope car only stays in the monitoring of the sliding rope car. When the rope sliding car occurs in the hoist, it can only be braked by the parking brake, and the moving steel wire rope and the hoisting car cannot be controlled. The container stops, resulting in a serious accident of slipping the rope and sliding the car cannot be avoided
