Technical Field

The invention relates to the technical field of mine transportation, in particular to an anti-falling device for an emergency stop protection pull rope of a belt conveyor.

Background

Mine transportation refers to underground transportation work of a mine, and mainly aims to transport out coal, transport waste gangue out of the ground, transport material equipment to a place where the material equipment is used, transport personnel to work and work, and the like. Useful minerals (ore, coal), waste rocks or waste rocks extracted underground are transported to ground transfer stations and washing and dressing plants from a mining working face or various transportation operations for transporting personnel, materials, equipment and other materials in and out, wherein the transportation operation from a shaft bottom yard to a shaft top belongs to mine hoisting. The mine transportation is characterized by large transportation volume, multiple varieties, narrow roadway, different transportation distances, complex line and short visible distance, thereby having complex operation, difficult maintenance and high safety requirement. In mines with the risk of gas and coal dust and mine dust explosions, the transport operations must strictly comply with the regulations relating to safety regulations. Mine transportation starts from manual basket carrying and basket pulling, and gradually develops to realize various mechanization and automation through manual mine pushing and car pulling and animal-drawn pulling. Before 1949, the transportation of Chinese mines is quite laggard, and the mechanization of the mine transportation is gradually realized later. Mine transportation is divided into the following parts according to transportation equipment: mine locomotive transportation, steel wire rope transportation, mine conveyor transportation, trackless transportation and hydraulic transportation (see a hydraulic coal mining method); the first two of which are also known as rail or rail transport. The transportation operation is divided into sections according to the transportation operation, and comprises the transportation of a working face and a mining area, the transportation of a stage or a main transportation roadway (a main roadway), the transportation of an inclined shaft and the ground transportation.

The pull rope of the emergency stop protection device of the belt conveyor used in the coal mine often drops, and due to the fact that a reliable locking device is not arranged, the pull rope drops in the process of pulling the pull rope, and due to the gravity of the pull rope, the pulling force is required to be increased, and if the pulling force is insufficient or the pull rope is clamped, the emergency stop protection device fails, and the pull rope is similar to a nominal pull.
