Self-adaptive passive cleaning robot for flammable and explosive dust pipelines

Abstract

The invention discloses a passive pipeline cleaning robot. A cleaning device and a pusing plate are arranged close to an air inlet and an air outlet respectively and are hinged through two supporting devices; one end of the cleaning device is coaxially connected with one end of the first supporting device, one end of the pushing plate is coaxially connected with one end of a second supporting device, and the other ends of the first supporting device and the second supporting device are flexibly hinged through a flexible connector; the cleaning device comprises a cleaning fixing shaft, a cleaning seat body, a plurality of cleaning assemblies, fan blades and a speed reducing mechanism; and the first supporting device and the second supporting device are the same in structure and each comprise a supporting shaft, a supporting arm, a supporting seat body, a left rotating wheel, a right rotating wheel and an elastic supporting assembly. The self-adaptive passive cleaning robot is short in transmission route, high in transmission efficiency, large in cleaning torque, high in working reliability, capable of preventing wheels from being abraded easily and more suitable for cleaning operation of bent pipelines, cleaning power and walking power do not interfere with each other, and power is sufficient.

Description

technical field [0001] The invention relates to a pipeline cleaning robot, in particular to an adaptive passive cleaning robot for inflammable and explosive dust pipelines. Background technique [0002] The existing scheme is usually: windshield - drive wheel rotation - synchronous belt drive - worm drive - flexible coupling - cleaning device, the structure increases the positive pressure of the drive wheel and the pipe wall, and the wheels are easy to clean. Wear and tear, work reliability is not high. [0003] The power device, cleaning device and support device of the existing scheme have the same elastic expansion mechanism, and all use the axial spring to compress the slider to generate axial movement to push the rocker to swing to change the radial size of the road wheel or cleaning head. This structure makes the axial dimension of these devices relatively long, which leads to an increase in the overall size of the robot, making it difficult for the robot to walk in c...

Problems solved by technology

[0002] The existing scheme is usually: windshield - drive wheel rotation - synchronous belt drive - worm drive - flexible coupling - cleaning device, the structure increases the positive pressure of the drive wheel and the pipe wall, and the wheels are easy to clean. Wear and tear, low working reliability

[0003] The power device, cleaning device and support device of the existing scheme have the same elastic expansion mechanism, and all use the axial spring to compress the slider to generate axial movement to push the rocker to swing to change the radial size of the road wheel or cleaning head. This structure makes the axial dimension of these devices relatively long, which leads to an increase in the overall size of the robot, making it difficult for the robot to walk in curved pipes, especially when turning, and it is easy to scratch the inner wall of the pipe, and the weight of the whole machine also increases.

In the existing scheme, the power generated by the windward plate is divided into transmission, one path is provided to the cleaning head, and the other path is used for the robot to walk. The transmission chain is long and the efficiency is low, which will cause insufficient power and power problems.
