Abstract

A pneumatic pipeline internal traveling device includes a frame, driving wheels and traveling wheels. The frame is provided with two traveling wheels, the driving wheels and two traveling wheels that are arranged sequentially in the direction of a central shaft of the frame, wherein seen from the axial direction, the traveling wheels are located at the lower semicircle of the frame, and the driving wheels are located at the upper semicircle of the frame; and on the radial distribution, the two traveling wheels are symmetric around an axis Y, the driving wheels are mounted at one end of a supporting arm through a pin shaft, the other end of the supporting arm is connected with a central shaft seat through a hinge, the central shaft seat is fixedly connected with the central shaft of the frame, the central shaft of the frame is glidingly sleeved with a sliding sleeve, the sliding sleeve is fixedly connected with a telescopic rod, the telescopic rod is connected with a driving cylinder, the sliding sleeve is connected with one end of a driving arm through a hinge, and the other end of the driving arm is hinged with the supporting arm; a pneumatic motor shaft, a rotating shaft of the supporting arm and a driving wheel shaft are equipped with chain wheels to transmit power from a pneumatic motor to the driving wheel. The pneumatic pipeline internal traveling device improves the positive pressures of the driving wheels and the traveling wheels on the pipeline wall, and is suitable for traveling in a steep pipeline.

Description

technical field [0001] The invention relates to a walking device in a pipeline. Background technique [0002] Pipeline robot is an essential tool in pipeline construction. The sealing of the pipeline and the working environment determine the difficulty of pipeline construction. From the structural point of view, it is mainly divided into wheeled pipeline robots, footed pipeline robots, crawler pipeline robots and peristaltic pipeline robots. Japan's Toshiba Corporation developed the first wheeled pipeline robot in 1997. In order to increase traction, the robot adopted multi-wheel drive, but the wheel diameter was too small, the ability to overcome obstacles was limited, and the structure was complicated; developed by Werner Neubern et al. There are three types of spider-type micro-pipe robots with 3, 6, and 8 legs. The principle is to use the legs to push the pipe wall to move, and the multi-legs can easily move in various shapes of curved pipes; Canada Inuktun and BioVac S...
