HDPE pipe pulling device
This utility model relates to the technical field, specifically to an HDPE pipe traction device, including a U-shaped base. Movable plates are slidably connected to the top two ends of the U-shaped base, and a clamp is provided on the top of the movable plate. Crossbars are fixed to both sides of the movable plate. This utility model supports the bottom of the pipe by setting up the support plate, while the clamp on the support plate can fix the middle or the other end of the pipe. This restricts pipe displacement, ensuring the pipe remains straight during connection and improving connection accuracy. It also reduces the pulling force on clamp one, distributing some of the pulling force and reducing the load on clamp one, thereby reducing the chance of slippage and ensuring smooth traction. This eliminates the need for repeated pipe tightening by personnel, improving convenience during use. Furthermore, since the sliding plate can slide on the crossbars, the positions of the support plate and clamp two can be adaptively adjusted according to the pipe length.
