Concrete Pipe roller machine is an ideal machine equipment for producing reinforced concrete pipes. The machine can produce reinforced concrete pipes with various joints with a length of 2-5m and an inner diameter of 300-2500mm.Suspended roller pipe making machine has:
1. Short production cycle; 2. Using dry hard concrete, no waste slurry.3. High production efficiency.

When the existing hanging roller pipe making machine performs pipe making operations, the rotation of the rotating shaft is often used to drive the pipe making mold. During the movement of the pipe making mold, due to the presence of centrifugal effect, the left and right shaking will occur. The nearby staff pose a safety hazard.
Therefore, it is necessary to design a suspended roller cement pipe making machine:
A suspension roller type cement pipe making machine includes a main frame, the main frame includes a fixing frame, the upper end frame of the fixing frame is fixed with a rotating shaft, and one end of the rotating shaft away from the fixing frame is connected and fixed with a supporting frame, so The side frame of the fixing frame is provided with a through hole transversely penetrating the side frame of the fixing frame, a threaded structure is arranged inside the through hole, and the fixing frame is connected and fixed with a protective fence capable of shrinking and stretching through the through hole. The protective fence forms an enclosed protection for the pipe-making mold, and one end of the protective fence away from the fixing frame is connected and fixed with the support frame.

By adopting the above-mentioned technical solution, the tube-making mold is enclosed by the protective fences of the retractable pull ropes provided on both sides of the main frame, which effectively prevents the mold from forming due to its own centrifugal movement during the tube-making process. The staff on both sides of the pipe machine caused injury.
The utility model is further configured as follows: the protection fence includes a plurality of door body frames, the two door body frames are connected and fixed by a cross plate, and the two cross plates are overlapped and hinged by a cross shaft.
By adopting the above technical solution, the protection fence is composed of a door frame and a hinged cross plate, so that the protection fence can be contracted, and the space occupied by the protection fence is effectively reduced.
The utility model is further configured as follows: a connecting block is fixed on one end of the door frame close to the fixing frame, a fixing groove is arranged on the side of the connecting block, and a bearing is sleeved and fixed in the fixing groove; the through hole is connected and fixed by a thread structure The push rod includes a rotating rod with a threaded structure on the surface, the rotating rod passes through the through hole and is rotatably sleeved with the bearing in the fixing groove, and one end of the rotating rod is fixed with a rotating wheel.
The utility model is further configured as follows: a connecting plate is fixed between the two side frames of the support frame, the connecting plate is provided with a through groove that penetrates the connecting plate in the elongation direction, and a sliding groove is connected in the through groove Clamping plate; one end of the door frame close to the support frame is fixed with a tension spring, and the tension spring is detachably connected to the clamping plate.
By adopting the above technical solution, the relative position of the protection fence on the main frame can be changed correspondingly through the above structure, and the pipe-making molds of different diameters can be well restricted and protected.
