Slope winch safety protection device and slope winch

Abstract

The invention relates to the technical field of winches, in particular to a slope winch safety protection device and a slope winch. The device comprises a first connecting shaft, a second connecting shaft, an elastic part, a first gear, a second gear, an electromagnet, a shifting piece, a first supporting seat and a second supporting seat. When the slope winch encounters sudden power failure in the transportation process, especially in the upward lifting transportation process, the electromagnet is suddenly in a power-off state, the electromagnet loses magnetism, the first gear and the secondgear can be connected together in a meshing mode under the action of resilience force of the elastic part, due to the fact that the second gear cannot rotate, after the first gear and the second gearmesh with each other, the first gear can be stuck and cannot rotate, a winding drum cannot rotate due to the rotation failure of the first gear, and the winding drum is safely braked, so that cargoesare effectively prevented from sliding downwards along a rail, the possibility of safety accidents is reduced, and the use safety of the slope winch is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of winches, in particular to a safety protection device for a slope winch and a slope winch. Background technique [0002] The slope hoist is mostly used in underground mines or open-air slope hoistways, coal mine slope hoistways, water pump stations, etc. The slope hoist includes a reel, which drives the wire rope to move through the clockwise or counterclockwise rotation of the reel, thereby driving the transportation of goods. The braking system of the slope hoist, that is, the braking system of the drum is the guarantee for the safe transportation of the hoist. At present, the braking system is mainly a set of brake shoes. The operating system of the brake shoes is set in the driver's control room. The operation of the brake system needs to be operated under the condition of electricity, so that when the hoist encounters a sudden power failure during transportation, especially during the upward lifting t...

Problems solved by technology

The braking system of the slope hoist, that is, the braking system of the drum is the guarantee for the safe transportation of the hoist. At present, the braking system is mainly a set of brake shoes. The operating system of the brake shoes is set in the driver's control room. The operation of the braking system needs to be operated under the condition of electricity, so that when the hoist encounters a sudden power failure during transportation, especially during the upward lifting transportation, the goods will reverse the reel under the action of its gravity , the cargo slides down the track, which may cause a safety accident. It can be seen that the existing slope hoist is less safe to use
