Auxiliary support for lap joint of heat supply pipelines

Abstract

The invention discloses an auxiliary support for lap joint of heat supply pipelines. The auxiliary support comprises a support member, a mounting base, a gas conveying channel, stop blocks and attaching pieces, wherein the inner end of the support member is in threaded connection with a threaded rod; the outer surface of the support member is in bearing connection with a movable rod; a first rotating shaft is arranged at the outer end of the movable rod in a penetrating mode; the upper end of the movable rod is in bearing connection with the mounting base; the outer side of the lower end of the movable rod is fixedly connected to a first pull rope; and the first pull rope is connected to the inner side of the support member. According to the auxiliary support for lap joint of the heat supply pipelines, an abutting piece making contact with a pipe fitting in advance is stressed along with automatic upward movement of the mounting base according to the height of the pipe fitting, and then the stop blocks connected to the abutting piece are stably driven to move inwards by the corresponding pull ropes through meshing structures between the abutting piece and gears, so that the workingeffect of automatic limiting is achieved on the outer side of the pipe fitting; and meanwhile, a third pull rope in butt joint with the upper end of the pipe fitting drives the two sets of attachingpieces to synchronously move downwards, and then the working effect of secondary self-limiting on the upper end of the pipe fitting is achieved.

Description

technical field [0001] The invention relates to the technical field of heating pipelines, in particular to an auxiliary support for overlapping heating pipelines. Background technique [0002] With the continuous development of urban construction, all kinds of industrial equipment are gradually increasing. Among them, the pipes that transport steam or hot water are called heating pipes, which can transport the heat energy produced by the boiler to indoor use through steam, hot water and other heat media. In order to meet the needs of production and life, the heating equipment needs to be adapted to the corresponding auxiliary supporting equipment during the lapping process. However, the existing auxiliary supports for overlapping heating pipes still have certain defects, such as: [0003] 1. The existing auxiliary brackets for lap joints of heating pipes do not have good support stability, which leads to unfavorable phenomena such as positional deflection when the pressure i...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an auxiliary support for heating pipe lapping, to solve the problem of lack of good support stability in the above background technology, which leads to the occurrence of positional deviation and other defects when the pressure is too large Phenomena, leading to certain defects in its support efficiency, and its limited support area, resulting in the inability to effectively guarantee the support strength per unit area, and unable to stably realize the self-limiting working effect on the pipe fittings that need to be supported. At the same time, its The support area is limited, which leads to certain safety hazards in the support stability during the operation of different types of pipe fittings
