The invention discloses a coal mine goaf filling auxiliary isolation device based on a pulley lifting technology, and relates to a mechanical device for underground coal mine filling isolation, in particular to a filling support auxiliary isolation device based on a pulley lifting structure. Due to the fact that the sealing effect on the top of a filling support and between supports is poor, slurry leakage and escape accidents are often caused, the production rate is low, the labor intensity is large, and the operation risk is high, the device adopts a flexible rubber pad top isolation structure which is tightly attached to a top plate, and thus the top sealing problem is solved. The tail of the support is fully isolated through isolation color band cloth, the problem of sealing between the supports is solved, and meanwhile due to the flexibility of the isolation color band cloth, the color band cloth is effectively prevented from being torn and damaged in the forward moving process of the support. A pulley block structure is designed, so that the requirement of the auxiliary isolation device on traction force can be reduced, and energy-saving, low-consumption and low-intensity mechanical operation is realized. The device is matched with a filling support to be applied to a goaf behind an isolation working face and serves as a to-be-filled area.

    “基于滑轮提升技术的煤矿采空区充填辅助隔离装置”的发明涉及一种煤矿井下充填隔离的机械装置,特别是涉及一种基于滑轮提升结构的充填支架辅助隔离装置。由于充填支架顶部、架间密封效果差,常引起漏浆、跑浆事故,生产率低、劳动强度大、作业风险高。因此,本发明采用柔性橡胶垫顶部隔离结构,与顶板紧密贴合,解决顶部密封难题。通过采用隔离彩条布对支架尾部进行全隔离,解决了架间密封难题,同时隔离彩条布的柔韧性,有效避免支架前移过程中的撕扯损坏。设计滑轮组结构可降低辅助隔离装置对牵引力的需求,实现节能、低耗、低强度的机械化作业。本发明装置与充填支架配套应用于隔离工作面后方的采空区,并作为待充填区域。
