The connection holes are provided on the tightening member to facilitate its connection with the tensioning device, saving time.
[0025] Further, as a preferred implementation manner rather than a limitation of this solution, the tensioning device 2 is a steel wire rope or a nylon rope, and the tensioning device 2 is arranged on both sides of the traction device 5. In this embodiment, tensioning devices are provided on both sides of the traction device, so that the forces on both sides of the traction device are evenly distributed during movement.
[0026] Further, as a preferred implementation manner rather than a limitation of this solution, the traction device 5 includes a frame 51 composed of square tubes welded or bolted together; universal wheels 55 fixedly connected to the bottom of the frame 51, enabling the frame 51 to move in any direction; a jack 52 arranged at the central axis position of one side of the frame 51 away from the pressing device 4, the jack 52 being fixedly connected to the frame 51, and the jack 52 propping against the inner wall of the first pipe fitting 31; a driving device 53 arranged inside the traction device 5, the driving device 53 being a motor or an electric hoist, the starting end of the tensioning device 2 being connected to the driving device 53, and after the driving device 53 is powered on, it rotates and contracts the tensioning device 2 to drive the traction device 5 to traction the first pipe fitting 31 to axially move towards the second pipe fitting 32; the traction device 5 extends into the first pipe fitting 31. In this embodiment, the universal wheels arranged at the bottom of the frame facilitate easily moving the traction device to the designated position during use, saving time and effort; the jack propping against the inner wall of the first pipe fitting ensures that the first pipe fitting is evenly and stably stressed longitudinally during movement; the driving device maintains a stable rotation speed by being powered on, and the traction device moves at a constant speed, reducing waste of manpower, and improving the fastening efficiency and fastening quality.
