Abstract

The invention discloses a pneumatic pipeline internal traveling device capable of braking reliably, which comprises a frame, a shoe brake, driving wheels and traveling wheels. The frame is provided with two traveling wheels, the shoe brake, the driving wheels and two traveling wheels 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 shoe brake and the driving wheels are located at the upper semicircle of the frame; on the radial distribution, the two traveling wheels are symmetric around an axis Y and mounted on the frame; the driving wheels are connected with a driving transmission mechanism; the shoe brake is connected with a brake transmission mechanism; a central shaft seat is fixedly connected with the frame central shaft; the frame central shaft is glidingly sleeved with an upper sliding sleeve and a lower sliding sleeve; the lower end of the lower sliding sleeve is fixedly connected with a telescopic rod of a driving cylinder; and the upper end of the upper sliding sleeve is fixedly connected with the telescopic rod of a brake cylinder. A pneumatic motor comprises a pneumatic motor shaft, wherein the pneumatic motor shaft, a rotating shaft and a driving wheel shaft are equipped with chain wheels to transmit power from the pneumatic motor to the driving wheel. The pneumatic pipeline internal traveling device can be used for braking reliably and safely.

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. Wheeled pipeline robots are usually pneumatic. The existing pneumatic pipeline internal walker brakes very unreliably when walking on slopes. On the one hand, the braking ability is weak, and on the other hand, the interlocking mode of the brake control valve and the travel control valve causes poor reliability. Contents of the invention [0003] In order to overcome the lack of braking ability of the existing pneumatic pipeline inner walker when walking on a slope, the invention provides a pneumatic inner pipeline walker capable of ...
