Lining cold rolling pipe expansion device

Abstract

The invention discloses a cold rolling pipe expanding device for linings. The cold rolling pipe expanding device comprises a base and a lining; the upper end of the base is sequentially provided witha first support, a fixing frame, a second support and a first motor from left to right, wherein the second support is provided with two first bearing seats from top to bottom, and an output shaft of the first motor is connected to one of the first bearing seats; the first support and the second support are connected with a first rotating shaft in a rotating mode, and the first rotating shaft is connected with the output shaft of the first motor through a belt transmission mechanism; a roller adopting conical structure sleeves the first rotating shaft; one end of the first rotating shaft is fixedly connected to the second support through the other one of the first bearing seats; and the first support is provided with a clamping device. The cold rolling pipe expanding device for the liningshas the advantages that structure is stable, operation is simple, design is scientific and reasonable, the production period is short, the device can be conveniently detached and fed, the radian of the device can be conveniently adjusted and fixed, so that the device is applicable to the linings of different specifications, a lot of time and energy of workers can be saved, and the device is worthyof popularization.

Description

technical field [0001] The invention relates to the technical field of pipe expansion devices, in particular to an inner liner cold rolling pipe expansion device. Background technique [0002] In the vast depths of the earth, especially around the major oil fields, there are a large number of oil, gas and sewage pipelines buried like a network. Most of these pipelines have been corroded, aged, and close to At the same time, many water supply pipelines in large and medium-sized cities have already leaked. If these pipelines are fully updated, pipe trenches need to be excavated. The amount of work is large, the cost is high, and the construction period is long. Public facilities cause a lot of inconvenience to the public. Therefore, how to repair and partially replace pipelines in a short period of time has always been an engineering project worthy of attention. [0003] The stainless steel lining technology began to be used in the mid-1960s. It uses thin-walled stainless ste...
