Abstract

A rescue and retraction device for underground excavation and mining equipment and its use method, which belong to the field of coal mine excavation and mining technology, can solve the problem of low rescue efficiency in existing coal mine excavation and mining working faces, high risk of roof falling twice, and high labor intensity of rescuers. Issues with major safety hazards, including the traction and withdrawal device, the two-arm bolt scraper and the traction chain, the two-arm bolt scraper transports the traction and withdrawal device to the rescue site, and performs necessary support and cleaning of the roof collapse area , connected with the traction retraction device controller and providing a power source, the traction retraction device is connected with the rescued equipment, and pulls the buried equipment away from the roof fall area. The present invention can timely rescue the buried equipment and avoid the risk of secondary roof fall, and The personnel working area is always in the safe area provided by the rescue system, which improves safety and reduces labor intensity. The rescue system can also be used as an auxiliary driving equipment when large-slope excavation equipment is in a nest, so as to improve the adaptability of the equipment.

Description

technical field [0001] The invention belongs to the technical field of coal mine excavation, and in particular relates to a rescue and withdrawal device for underground excavation equipment and a use method thereof. Background technique [0002] Coal mine underground excavation and mining equipment is at the forefront of underground roadway development. Due to the inability to achieve timely support during the excavation and mining process, the area where the excavation and mining equipment is located is prone to roof collapse, chipping, etc., and equipment is buried, crushed, and stuck Accidents happen all the time. In particular, the continuous miner is in the pressure island area in the corner coal mining, the mine pressure is abnormal, and the roof fall accidents occur frequently. After the roof fall accident, there is no professional rescue system equipment, and the rescue of the equipment requires a large number of personnel to carry out gangue cleaning and rescue wor...
