A pneumatic means for pipeline threading

The utility model discloses a pneumatic means for pipeline threading is particularly useful for wearing the feelings type of fine rule in long pipeline, the device includes observation window on shell, the shell, fixes the air compressor of the sealed bearing on the shell, the pivot of crossing the shell and handle, the epaxial spool of commentaries on classics and shell bottom and treat threading pipeline interface, during the threading, pipeline and the air compressor machine of treating the threading with correspond interface sealing connection, the epaxial linear system of line is on the piston, the piston is placed in the pipeline, provide the high pressure draught through the air compressor machine, promote the pipe in piston motion deviate from from the other end until the piston, accomplish the threading. 本实用新型公开了种用于管道穿线的气动装置，尤其适用于在长管道中穿细线的情型，该装置包括外壳、外壳上的观察窗、固定在外壳上的密封轴承、横穿外壳的转轴及手柄、转轴上的线轴以及外壳底部的空气压缩机和待穿线管道接口；穿线时，待穿线的管道和空压机与对应接口密封连接，线轴上的线系在活塞上，活塞置于管道里；通过空压机提供高压气流，推动管中活塞运动直至活塞从另端脱出，完成穿线。
