Abstract

The invention relates to the technical field of tensile compression installation of expansion joints, in particular to a tensile compression tool and a large-displacement tensile compression method ofan expansion joint. The tensile compression tool comprises a first fixed fixture, a second fixed fixture and a drive device, wherein a first holding space is formed between two first vertical platesand a first bottom plate of the first fixed fixture and is used for installing a first flange of the expansion joint; and a second holding space is formed between two second vertical plates and a second bottom plate of the second fixed fixture and is used for installing a second flange of the expansion joint. Therefore, the first fixed fixture and the second fixed fixture can be arranged on the corresponding first flange and the corresponding second flange, and the drive device can drive the second flange to move relative to the first flange so as to stretch or compress a corrugated pipe between the two flanges, so that the expansion joint is quickly and stably loaded, and especially, unilateral stretching or compressing loading operation can be realized; and the tensile compression tool is simple, convenient and easy to install, disassemble and adjust.

Description

Technical field [0001] This application relates to the technical field of expansion joint tension and compression installation, in particular to a tension and compression tooling and a large displacement tension and compression method for expansion joints. Background technique [0002] At present, a gas-insulated metal-enclosed transmission line (GIL) is a transmission line that uses a conductive rod enclosed in a grounded metal shell to transmit electrical energy and uses pressure gas insulation. The main components include: high-voltage conductor and grounding shell, insulator, sliding contact assembly and expansion joint (metal compensator). Among them, the expansion joint is mainly used for installation and adjustment, absorbing the relative displacement between the foundations, and absorbing the displacement of the pipeline caused by thermal expansion and contraction. It is a very important part of the GIL. The construction of pipe gallery is a kind of gas-insulated metal e...
