Traveling device for detecting internal quality of concrete pipeline and operation method

Abstract

The invention provides a traveling device for detecting the internal quality of a concrete pipeline and an operation method. The traveling device comprises a rack structure. A head traveling wheel setand two head supporting wheel sets used for supporting the inner wall of the pipeline to travel are connected to a first middle supporting plate of the rack structure. A tail traveling wheel set andtwo tail supporting wheel sets used for supporting the inner wall of the pipeline to travel are connected to a second middle supporting plate of the rack structure. The rack structure is provided witha head opening device used for driving the head traveling wheel set and the head supporting wheel sets to open symmetrically. The head opening device is connected with a tail opening device through asynchronous transmission mechanism. The tail opening device is connected with the tail supporting wheel sets and the tail traveling wheel set in a matched mode. The traveling device can carry a concrete quality detection device and a camera device to detect the internal quality of the concrete pipeline so as to ensure the detection quality.

Description

technical field [0001] The invention relates to the field of construction concrete quality detection devices, in particular to a walking device and an operation method for internal quality detection of concrete pipelines. Background technique [0002] In the process of building construction or municipal infrastructure construction, concrete pipes are needed. Concrete pipes are mainly used for sewage discharge or laying of electricity and networks. During the construction process, their quality needs to be tested. Due to the limited space inside the pipes, and The length is long, and there are certain joints at the joints of adjacent pipelines. After the construction or pipeline laying is completed, the internal quality of the concrete pipeline needs to be inspected, mainly including the inspection of the surface quality of the pipeline lining and the quality inspection of the joints. , in the detection process, the pipeline robot is usually equipped with corresponding camera...

Problems solved by technology

[0003] Although there are many different structures and types of pipeline walking devices, for example: CN 110159869 A discloses a pipeline detection robot and its multi-sensor fusion detection method, which carries three groups of walking components on the main frame to realize The walking of the whole robot uses a quadrilateral linkage mechanism in order to adapt to different pipe diameters, but the structure of the above-mentioned robot is relatively complicated, and the stability of the structure cannot be well guaranteed

[0004] A pipeline robot is disclosed in CN20301011, which adopts multiple joints, and mainly solves the problem of smooth walking inside the variable-diameter pipeline. It connects the two joints through a turning mechanism. Although it is disclosed that the thread transmission is used to achieve stretching, its In essence, it cannot be in good contact with the inner wall of the pipeline, and cannot achieve normal walking

[0005] A pipeline detection robot is disclosed in CN105276334, which adopts a universal joint and a multi-stage belt-driven rocker mechanism to realize walking close to the inside of the pipeline, but the above-mentioned belt-type rocker mechanism cannot actually control the inner wall of the pipeline well. The fit, its walking stability cannot be controlled, and the structure is relatively complicated
