Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-4, the utility model relates to a plugging device for pressure test of lining pipe, its constitution includes: 1-winding an extrusion shaft; 2-fixing the extrusion clamp.
1-winding the extrusion shaft to meet the requirement of 3-winding the shaft-shaped part folded in half by the lining pipe. The outer diameter of the steel pipe is determined according to the bending and folding radius of the 3-lining pipe and the comprehensive design of bending resistance and extrusion resistance. The connecting flange at the end part is connected with the connecting hole at the end part of the 2-fixed extrusion clamp by adopting a bolt, so that the stability of the 1-winding extrusion shaft is maintained in the pressure test process, and the safety of the structure is improved. The width between the connecting flanges at the two ends meets the maximum size of the 3-lining pipe, and the 3-lining pipe exceeding the width needs to adopt a wider plugging device and can be used when the width is not exceeded.
The 2-fixed extrusion clamp is a clamp for clamping a 3-lining pipe, a steel plate is bent into a groove shape or heavy channel steel to serve as a machine body, a thin steel rod-shaped structure with a smaller diameter is welded in the part, which is in vertical surface contact with the 3-lining pipe, of the pipe, the thin steel rod-shaped structure is welded in the part, which is in transverse arrangement along the machine body, of the pipe, the steel rods which are arranged oppositely are arranged in a staggered mode, and the steel rods and the aligned machine body plate face form multi-gap extrusion on the 3-lining. 2-the fixed extrusion fixture is two same fixtures, and is designed and manufactured in a symmetrical mode, bolt holes for connecting and fixing the two fixtures are formed in two ends of the machine body groove-shaped part, the two fixtures are fastened through the bolts, and at the moment, the inner steel rod-shaped structure extrudes the 3-lining pipe to form fixing and sealing.
