A self-limiting support device for maintenance of municipal pipelines that is easy to disassemble

Abstract

The invention discloses a convenient-to-disassemble and assemble self-limited supporting device for municipal pipeline overhauling. The device comprises a base body, a containing groove, a supportingblock and a movable block, wherein the containing groove is formed in the inner side of the upper end of the base body, and the supporting block is arranged on the outer side of the containing groovein a penetrating mode; first pull ropes are connected to the outer side of the lower end of the supporting block through bearings, and the first pull ropes are connected with the inner surface of theupper end of the base body; and connecting shafts are arranged at the outer end of the base body in a nested mode, the connecting shafts are connected with the tail ends of the first pull ropes, and first torsional springs are fixedly connected to the outer surfaces of the middle ends of the connecting shafts. According to the convenient-to-disassemble and assemble self-limited supporting device the for the municipal pipeline overhauling, a pipe fitting applies pressure to the supporting block through the dead weight of the pipe fitting, and then two arc-shaped limiting blocks are stably driven to move oppositely through transmission force between the first pull ropes, so that transverse guide wheels on the inner sides of the limiting blocks are stably matched, and the requirement for transverse movement of the pipe fitting is met while the device carries out self-limiting on the pipe fitting.

Description

technical field [0001] The invention relates to the technical field related to municipal administration, in particular to a self-limiting support device for municipal pipeline maintenance that is easy to assemble and disassemble. Background technique [0002] With the continuous improvement of people's quality of life, the quality of urban management is also constantly improving, and the municipal industry includes a variety of projects, among which the municipal pipeline is one of the important items to maintain the urban underground water supply and gas supply. After a long period of use, it needs Professionals carry out regular inspection and maintenance or replacement work, so pipe support devices need to be used during the inspection and repair process. However, the existing support devices for municipal pipeline inspection still have certain defects, such as: [0003] 1. For example, the liftable pipeline support device whose publication number is CN207298070U, it sets...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a self-limiting support device for maintenance of municipal pipelines that is easy to disassemble, so as to solve the problem that the above-mentioned background technology can only support pipelines of a single type of diameter, and cannot be stable and self-adaptive. Different municipal pipelines carry out limit work, and most of the installation methods are relatively cumbersome. They need to be operated and fixed by responsible installation objects such as bolts, which cannot allow users to conveniently disassemble and install the device and the pipe fittings required for maintenance.
