Abstract

The invention relates to a rescue withdrawing device for underground excavation equipment and a use method of the rescue withdrawing device, belongs to the technical field of coal mine excavation, andcan solve the problems of the low rescue efficiency of an existing coal mine underground excavation working surface, the high risk of secondary roof caving, the high labor intensity of rescue workersand the high potential safety hazard. The rescue withdrawing device comprises a traction withdrawing device, a two-arm anchor rod scraper and a traction chain, wherein the two-arm anchor rod scrapercarries the traction withdrawing device to a rescue site, conducts necessary supporting and cleaning on a roof caving area, is connected with a traction withdrawing device controller, and provides a power source, and the traction withdrawing device is connected with rescued equipment and pulls the buried equipment to evacuate from the roof caving area. According to the device, the buried equipmentcan be rescued in time, the secondary roof caving risk is avoided, a personnel operation area is always located in a safety area provided by a rescue system, the safety is improved, meanwhile, the labor intensity is relieved, the rescue system can also be used for auxiliary driving equipment when large-gradient tunneling equipment is stopped, and the adaptability of the equipment is improved.

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...
