Assembly and disassembly tool for clamping-pressing type mechanical connector

Abstract

The invention provides an assembly and disassembly tool for a clamping-pressing type mechanical connector. The assembly and disassembly tool for the clamping-pressing type mechanical connector comprises an axial hydraulic cylinder loading mechanism and a hydraulic cylinder open-close mechanism. The axial hydraulic cylinder loading mechanism is composed of two half parts which are symmetrical in a left-right mode. The two half parts are axially and sequentially loading mechanism clamping claws, loading hydraulic cylinder pistons and loading hydraulic cylinder base seats from front to back. The loading hydraulic cylinder pistons are connected with the loading mechanism clamping claws. The left loading hydraulic cylinder base seat is connected with the right loading hydraulic cylinder base seat through a connecting hinge. Semi-circle grooves of the connector are formed in the central sides of the left hydraulic cylinder base seat and the right hydraulic cylinder base seat. Hydraulic cylinder base seat convex platforms are arranged inside the semi-circle grooves. The hydraulic cylinder open-close mechanism comprises an open-close hydraulic cylinder which is fixed between the left hydraulic cylinder base seat and the right hydraulic cylinder base seat through supports. Assembly and disassembly of the clamping-pressing type mechanical connector can be achieved rapidly.

Description

Technical field [0001] The invention relates to a pipeline connecting device. Background technique [0002] The compression mechanical connector has the advantages of simple configuration, high sealing pressure, complex working environment, and it can bear a certain axial force and bending moment of the pipeline in place. Its sealing principle is reliable by the extrusion deformation of the metal surface The ring-shaped sealing surface is sealed, so the installation of the press-type mechanical connector requires a large load force, and the installation process must be carried out smoothly; in the same way, due to the effect of external environmental factors or the internal reasons of the mechanical connector, the connector When it fails, the connector must be removed from the pipeline and replaced with a new connector. The special environment in which the connector works often hinders the implementation of traditional disassembly methods such as cutting, and the disassembly of t...

AI Technical Summary

Problems solved by technology

[0002] The press-type mechanical connector has the advantages of simple structure, high sealing pressure, adaptability to complex working environment, and can withstand certain in-position axial force and bending moment of the pipeline. Its sealing principle is to form a reliable seal by extrusion deformation of the metal surface. The annular sealing surface of the mechanical connector is sealed, so a large loading force is required to complete the installation of the press-type mechanical connector, and the installation process must be carried out smoothly; similarly, due to external environmental factors or internal reasons of the mechanical connector, the connector may be damaged. When it fails, the connector must be removed from the pipeline and replaced with a new connector. Some special environments in which the connector works often hinder the implementation of traditional disassembly methods such as cutting, and the disassembly of the connector requires a lot of work. The axial pull-out force is completed, which limits the wide application of press-type mechanical connectors
