AI Technical Summary

Technical Problem

The existing dredging machinery can only be used for single-size drainage pipes, resulting in a narrow scope of application and cannot effectively solve the problem of blockage in the railway tunnel drainage system.

Method used

A self-adaptive-diameter railway tunnel drainage pipe dredging device is designed, using a guide mechanism and a support mechanism. Through the combination of moving rods and micro springs, adaptive dredging of pipes of different inner diameters is achieved, and the shaking of the blocked soft shaft is restricted through the support mechanism to reduce the destructive impact on the pipeline wall.

Benefits of technology

The device can adapt to rail tunnel drainage pipes with different inner diameters for dredging, significantly expanding the scope of application and reducing the destructive impact of dredging operations on the pipeline wall.

Abstract

The utility model relates to the technical field of pipeline desilting, and solves the problem that most desilting machines can only desilt drainage pipelines with single sizes, so that the application range of a sewage pipeline desilting device is narrow. The self-diameter-adaptive railway tunnel drainage pipeline dredging device comprises a dredging mechanism which forms an acting surface on drainage pipeline sludge, and a supporting mechanism which circumferentially surrounds the dredging mechanism to support the dredging mechanism and comprises two fixed connecting rings, the two fixed connecting rings are connected through a fixed rod, and the fixed rod is connected with the dredging mechanism. A plurality of fixed side plates used for forming a central supporting surface are arranged in the two fixed connecting rings, a camera used for observing the working condition in the pipeline is arranged on one of the fixed side plates, and the guide mechanism is arranged between the two fixed connecting rings, is used for self-adapting to the change of the pipe wall and is provided with a guide rail connected with the fixed connecting rings; and two moving rods penetrating through the guide rail are mounted on the guide rail in a bilateral symmetry manner.
