1. The utility model provides an adjustable angle undergauge machine, includes undergauge machine, basic frame, connects otic placode, hinge pin, adjusting nut, adjusting screw, earth anchor, characterized by: the connecting lug plate of the reducing machine is hinged with the base frame through a hinge pin, the front end of the base frame is provided with an adjusting screw rod, the adjusting screw rod penetrates through a corresponding hole in the reducing machine, an adjusting nut is respectively arranged above and below the hole, and the reducing machine rotates by a certain angle around the hinge pin by rotating the adjusting nut.

One, the technical field

The invention relates to a plastic pipe reducing machine used in equal-diameter penetration construction, in particular to a reducing machine with an adjustable included angle between the central line of the reducing machine and the horizon during construction.

Second, background Art

At present, the angle of the diameter reducing equipment for the equal-diameter insertion repair of the pipeline cannot be adjusted, so that the included angle between a plastic pipe and the pipeline to be repaired is large after the plastic pipe is machined by the diameter reducing machine, the plastic pipe is bent in a transition mode, the construction difficulty is increased, the surface of the plastic pipe can be damaged, and the construction quality is reduced.

Third, the invention

The invention aims to provide an angle-adjustable reducing machine, which can adjust the included angle between the central line of a reducing pipe and the horizon according to the construction terrain when the equal-diameter penetration repair construction of a pipeline is carried out. The included angle between the plastic pipe and the pipeline to be repaired from the diameter reducing machine is reduced, the construction difficulty is reduced from the surface, and the construction quality is improved.

The technical scheme is as follows:

the purpose of the invention is realized as follows: the foundation frame is placed on a working foundation and fixed by the ground anchor, the connecting ear plate of the reducing machine is hinged with the foundation frame through the hinge pin, the front end of the foundation frame is provided with the adjusting screw rod, the adjusting screw rod penetrates through the corresponding hole on the reducing machine, the upper part and the lower part of the hole are respectively provided with the adjusting nut, and the reducing machine can rotate by a certain angle around the hinge pin by rotating the adjusting nut, so that the included angle between the reducing machine and the foundation is adjusted.

Has the advantages that:

by adopting the technical scheme, when the equal-diameter interpenetration repair construction of the pipeline is carried out, the included angle between the plastic pipe and the pipeline to be repaired can be reduced, so that the construction difficulty is reduced, and the construction quality is improved.

Description of the drawings:
