[0004] The composite pipe joint butt assembly pipe pressing device provided in the present application adopts the following technical solution:

[0005] A composite pipe joint butt assembly pipe presser comprises a connecting body for fixing the joint, a fixing block is arranged on the top wall of the connecting body, a driving block is arranged on the side wall of the connecting body, a transmission shaft is rotatably connected between the fixing block and the driving block, a transmission wheel is arranged on the transmission shaft, a driving cavity is opened in the driving block, a transmission gear set is arranged in the driving cavity, a winding main shaft is rotatably connected in the connecting body, the transmission shaft and the winding main shaft are both connected to the transmission gear set, a traction rope is arranged on the peripheral wall of the winding main shaft, and a valve for fixing the composite pipe is arranged on the end of the traction rope away from the winding main shaft.

[0006] By adopting the above technical scheme, the joint is fixed to the connecting body, and then the Chava is sleeved on the composite pipe so that one end of the composite pipe is aligned with the joint, and the transmission wheel is rotated to drive the transmission shaft to rotate. Under the transmission of the transmission gear set, the winding main shaft rotates, driving the traction rope to gradually wind around the peripheral wall of the winding main shaft. In this process, as the traction rope is continuously wound, the Chava and the composite pipe fixed by the Chava will also be driven to move toward the joint, thereby completing the docking of the composite pipe and the joint. The operation is convenient, saving working time and physical strength of the staff, and effectively improving the efficiency of docking the composite pipe and the joint.

[0007] Optionally, the peripheral wall of the winding main shaft is provided with two winding rope clamping shafts for limiting the traction rope.

[0011] Optionally, a mounting hole is opened on the surface of the transmission wheel, and a force rod is arranged in the mounting hole.

[0012] By adopting the above technical solution and providing a force adding rod, the workers can more easily rotate the transmission wheel and the transmission shaft, thus saving the workers' physical strength and further improving the assembly efficiency of the composite pipe and the joint.

[0013] Optionally, a manual wrench transmission clamp shaft is provided on the side wall of the fixed block, the manual wrench transmission clamp shaft is coaxially arranged with the transmission shaft, and the manual wrench transmission clamp shaft is connected to the transmission shaft.

[0014] By adopting the above technical solution, the manual wrench transmission clamp shaft provides the pipe presser of the present application with another form of power output in addition to the transmission wheel. Compared with the transmission wheel, the manual wrench transmission clamp shaft has the advantage of occupying less space, so that the pipe presser of the present application can operate in a small space, and has high applicability and flexibility.

[0015] Optionally, the Chava includes two semicircular tubes hinged to each other and a locking screw for fixing the two semicircular tubes.

[0016] By adopting the above technical solution, the Chava is provided with two semicircular tubes that can be hinged to each other, which improves the convenience of assembling the composite pipe and the Chava, and further improves the docking efficiency of the composite pipe and the joint.

[0017] Optionally, the inner wall of the driving cavity is rotatably connected to a gear block for positioning the transmission gear set.

[0018] By adopting the above technical solution, the gear block positions the transmission gear set, which can effectively prevent the transmission gear set from deflecting, so as to maintain the stability of the transmission gear set.

[0019] Optionally, the connection body is provided with a mounting groove for installing the joint, and a connection body clamping shaft is arranged below the mounting groove.

[0020] By adopting the above technical solution, the connecting spindle clamping shaft can tighten the lower end of the joint installed in the installation groove, thereby maintaining the installation stability of the joint and the connecting body, so that the docking of the joint and the composite pipe is more accurate and convenient.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. Fix the joint and the connecting body, then put the Chava on the composite pipe, align one end of the composite pipe with the joint, rotate the transmission wheel, drive the transmission shaft to rotate, and under the transmission of the transmission gear set, the winding main shaft rotates, driving the traction rope to gradually wind around the peripheral wall of the winding main shaft. In this process, as the traction rope is continuously wound, the Chava and the composite pipe fixed by the Chava will also be driven to move toward the joint, thereby completing the docking of the composite pipe and the joint. The operation is convenient, saving working time and physical strength of the staff, and effectively improving the efficiency of docking the composite pipe and the joint;
