Cable duct bank dredging robot capable of self-adapting to shape of pipeline

Abstract

The cable duct bank dredging robot comprises a front cabin and a rear cabin, multiple sets of first walking wheels capable of rotating in one direction are arranged on the periphery of the rear cabin, the multiple first walking wheels in the same set are arranged along a spiral line, and the axis of each first walking wheel and the axis of the rear cabin form a set acute angle; the end, close to the front cabin, of the rear cabin is fixed to a first thrust washer of a thrust bearing, a second thrust washer of the thrust bearing is fixed to a connecting piece, the connecting piece is connected with an output shaft of a walking driving piece located in the front cabin, a shell of the walking driving piece is fixed to the front cabin, the connecting piece is in universal connection with the front cabin, and a cleaning mechanism is installed in the front cabin. The robot is high in adaptability to the shape of the pipeline.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a cable pipe dredging robot capable of adapting to the shape of pipes. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The cable line project is to lay the cable pipes underground along with the road construction process in advance. When it is necessary to add cables to clear the lines later, the cables are directly passed through the underground preset pipelines to realize the line laying. The large-scale application of cable conduit is becoming the mainstream. [0004] This kind of pre-embedded construction scheme also exposed some problems during the application process, the most prominent one is the problem that the cable pipes cannot be used normally or are directly discarded due to foreign matter entering and blocking. The common blockage is caus...

Problems solved by technology

The pipeline robot can realize adsorption, fixation and crawling work on the inner and outer walls of large and small pipelines. It is equipped with sensors, robotic arms and other operating devices, and it can be executed automatically under the instructions of the pre-designed program or semi-automatically under the remote control of the control technician. The operation tasks in the pipeline can realize the cleaning of the blockage in the cable pipe. The cable pipe dredging robot currently used adopts a relatively mature peristaltic pipeline robot, which is generally divided into a front cabin and a rear cabin. The cylinder is connected, and the cylinder can expand and contract, thereby driving the whole robot to move forward in a peristaltic manner. However, the inventors found that the peristaltic robot in this way is only suitable for traveling in a straight line pipeline, and the ability to adapt to the shape of the pipeline is poor.
