ActiveCN111927530BSimple structureNo maintenanceMining devicesSafety equipmentsArchitectural engineeringRock bolt
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.
