Oil and gas pipeline directional drilling crossing auxiliary pull-back device

The utility model relates to the technical field of oil and gas pipeline crossing construction, in particular to an oil and gas pipeline directional drilling crossing auxiliary pull-back device. According to the technical scheme, the device mainly aims at solving the problems that when an existing device assists an oil and gas pipeline in moving, the oil and gas pipeline is likely to be separated from a roller, meanwhile, the inclination angle of the roller is not conveniently adjusted according to the diameter change of the oil and gas pipeline, and practicability is poor. Positioning screws for fixing the position of the base are arranged on the base, turnover frames are installed on the top of the base, auxiliary mechanisms for assisting the pipeline in moving are arranged on the two turnover frames respectively, and portal frames for assisting the auxiliary mechanisms in position fixing are symmetrically welded to the top of the base. Adjustment is carried out according to pipelines with different diamete
