車をもつ、 上記の機能を備えた管の変形防止装置。[Scope of Claim for Utility Model Registration] (a) A reinforcing ring made of shaped steel, etc. whose outer diameter is the inner diameter of the pipe, with two circular arcs of equal length on the left and right with the apex of the pipe as the dividing point and the center at the lowest point. 3 in one arc
It is divided into three arcs with pin hinges at two points: a point that connects the upper ends of the left and right arcs, and a point that connects the lower end of one of the left and right arcs to one end of the adjacent lower arc. (b) A hydraulic cylinder is attached between each arc and a mechanism is provided to enable bending action.When the cylinder is pushed, it creates the circumference of the inner diameter of the tube, and when it is pulled, the two hinge pins can be folded up and down. C. A link lever-shaped wedge operated by a hydraulic cylinder is provided at one end of the triple arc, and the wedge is press-fitted into the gap created at the tip of the ring formed by the triple arc, and the triple arc is fixed to the inner surface of the pipe as a ring. D. A pipe deformation prevention device with the above functions, which has a trolley that holds a fulcrum with a triple-arc lifting cylinder.
