Abstract

The invention relates to a pneumatic-crawler traveling mechanism in a pipeline, which comprises a frame, driving wheels and traveling wheels, wherein two traveling wheels, the driving wheels and two traveling wheels are arranged on the frame orderly along a central shaft of the frame; looked from an axial direction, the traveling wheels are located on a low semi-circle of the frame; the driving wheels are located on an upper semi-circle of the frame; two traveling wheels are distributed on a radial direction symmetrically around a Y axle; the traveling wheels are mounted on the frame; the driving wheels are mounted on one end of a support arm through a pin shaft; the other end of the support arm is linked to a sliding sleeve through a hinge; the support arm can be rotationally mounted on a gyrating shaft; a central shaft base is fixedly connected with a frame central shaft; the sliding sleeve can be sleeved on the frame central shaft in a sliding manner; the sliding sleeve is connected with a first driving air cylinder; an air motor is mounted on a machine frame; chain wheels are mounted on an air motor shaft, the gyrating shaft and driving wheel shafts; and power is transmitted from the air motor to the driving wheels. According to the invention, crawler wheels are used, so that positive pressure of the driving wheels, the travelling wheels and a pipeline wall is improved; and the pneumatic-crawler traveling mechanism is adapted to travel in a large-gradient pipeline.

Description

technical field [0001] The invention relates to a walking mechanism in a pipeline. Background technique [0002] The sealing of the pipeline and the working environment determine the difficulty of pipeline construction. Pipeline robot is an essential tool in pipeline construction. Today, through the efforts of scholars from various countries, various pipeline robots have emerged. From the structural point of view, it is mainly divided into wheeled pipeline robots, footed pipeline robots, crawler pipeline robots and peristaltic pipeline robots. Wheeled pipeline robots are usually pneumatic. 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 pri...
