Abstract

The invention discloses a mounting device used for a T-shaped joint nodular cast iron pipe. The mounting device comprises an open hoop with a hinge, a power steel block, a power screw, an auxiliary steel block, an auxiliary screw, power polish rods, lantern rings and three-joint universal joints. The open hoop with the hinge is composed of a moment input hoop and a moment output hoop. The power steel block is composed of a right-hand thread hole steel block, a left-hand thread hole steel block, two thread-free through hole steel blocks. The power screw is composed of a right-hand thread powerscrew and a left-hand thread power screw. The auxiliary steel block is composed of eight steel blocks with thread-free through holes. The auxiliary screw is composed of four right-hand thread screws.The total number of the power polish rods is two, the total number of the lantern rings is four, and the total number of the three-joint universal joints is two. The device is reasonable and simple instructure, light and small in requirement of operation space; and compared with the traditional mounting manner of mounting the T-shaped joint nodular cast iron pipe through a guide chain, operationof the device is more convenient, rapid and reliable, and the device has popularization value.

Description

technical field [0001] The invention relates to the technical field of ductile iron pipe installation, in particular to an installation device and an installation method for T-shaped joint ductile iron pipes. Background technique [0002] Ductile iron pipes are often used in the installation of water supply and drainage, gas and other pipelines. There are many types of interface. The ductile iron pipe with T-type interface is a socket connection. The socket and the socket are sealed by a rubber sealing ring. The outdoor installation of cast iron pipes usually uses guide chains, crowbars, excavators, etc. for installation, and the T-shaped joint ductile iron pipes installed indoors are generally installed with guide chains, using traditional installation methods such as guide chains, crowbars, and excavators. The biggest difficulty is that during the socketing process of the pipe / fitting, due to the uneven friction force between the socket and the rubber ring, the angle betwe...
