| description | A ground direction adjusting device for laying a horizontal pipeline in a soft stratum comprises an outer sleeve, an inner sleeve and a weight reducing assembly. The outer sleeve and the inner sleeve can slide relatively and cannot rotate relatively; the weight reduction assembly is installed in an inner hole of the inner sleeve and comprises a plane thrust bearing and a connector. The connector is movably installed in an inner hole of the inner sleeve through the plane thrust bearing and can rotate relative to the inner sleeve, one end of the connector is a drilling machine power end, and the other end of the connector is a drill rod output end. The device is used for horizontally laying the pipeline in a soft and broken stratum, so that effective extraction of coalbed methane in the coalbed becomes possible, the high-quality energy is effectively utilized, the greenhouse effect negative influence caused by direct discharge of the high-quality energy is avoided, the probability of gas accidents during coal m |
