Main mechanism of pipeline crossing device for preventing track deviation and device

Abstract

The invention discloses underground pipeline detection techniques and provides a main mechanism of a pipeline crossing device for preventing track deviation and the device. The main mechanism comprises a sliding mechanism arranged on a linear guide rail and a supporting hinge mechanism hinged to the sliding mechanism. The sliding mechanism is connected with an elastic piece arranged on the linear guide rail. The other end of the elastic piece is fixed to the linear guide rail. The supporting hinge mechanism comprises three or more supporting rods and limiting rods, wherein the supporting rods are hinged to the sliding mechanism, and the limiting rods are hinged to the supporting rods. The supporting rods are evenly arranged on the sliding mechanism with the linear guide rail as the center. The other end of each limiting rod is hinged to the linear guide rail. The device comprises two main mechanisms which are connected through a universal coupling. The device can be adapted to detection of underground pipelines with different diameters; in addition, the situation that the pipelines deviate from pipeline center lines under the influences of the factors such as the gravity can be avoided, so that the accuracy of detection data is greatly improved, and safety use of the pipelines is guaranteed.

Description

technical field [0001] The invention relates to an underground pipeline detection technology, in particular to a main mechanism and a device of a pipeline crossing device for preventing track deviation. Background technique [0002] Urban underground pipelines are the basis and guarantee for the survival and development of cities, and the nerves and blood vessels to ensure the normal functioning of cities and people's living and working in peace and contentment. There are many kinds of underground pipelines, the main ones include water supply, drainage, gas, electrical, communication and industrial pipelines, etc. For different pipelines and types, the materials, sizes and burial methods of pipelines are different. During the maintenance stage, it is necessary to detect the actual condition of the pipeline to make timely replacement, repair or move measures to ensure the safety performance of the pipeline. [0003] With the development of underground pipeline detection tech...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome that the detector carrier used in the existing underground pipeline non-excavation detection cannot adapt to underground pipelines of different diameters, and cannot avoid gravity and other factors to make it deviate from the pipeline centerline, so that the pipeline can not pass through the carrier smoothly and accurately. Through underground pipelines, the accuracy of pipeline detection data cannot be guaranteed, and a main mechanism and device of a pipeline crossing device that prevents track deviation is provided. This device can adapt to the detection of underground pipelines with different diameters, and can avoid factors such as gravity It affects its deviation from the centerline of the pipeline, greatly improving the accuracy of the detection data and providing a guarantee for the safe use of the pipeline
