Automatically revolving robot used for cleaning shrimp curved pipe

Abstract

Disclosed is an automatically revolving robot used for cleaning a shrimp curved pipe. The automatically revolving robot used for cleaning the shrimp curved pipe is composed of a walking trolley, a constant force pushing mechanism, a revolving mechanism and a sweeping mechanism. Four hemispherical wheels are installed on the walking trolley, a motor is matched with a worm decelerator to drive the hemispherical wheels to walk. An air pump, a hydraulic pump, a hydraulic oil tank and the like are integrated on a trolley frame. The constant force pushing mechanism pushes tensioning wheels through a cylinder. According to the revolving mechanism, the motor drives the worm decelerator to drive an L-shaped revolving arm to rotate. A brush body beam can move on the revolving arm, and the brush body beam and the revolving arm operate synergistically to ensure that brush body moves along the axis of the shrimp curved pipe all the time. The brush body is composed of a plurality of small brushes, and each small brush is formed by the process that a thin wire is rolled on a thick steel wire. A dust collecting pipe is fixed under the brush body, so that real-time dust collecting is achieved, and the sweeping effect is guaranteed. After working, the L-shaped revolving arm can be taken back into a trolley body to enable the brush body to be located in front of the trolley body.

Description

technical field [0001] The invention relates to robot technology, in particular to pipeline robot technology for cleaning shrimp bends. Background technique [0002] At present, the gas gathering and transportation of natural gas adopts the process of high-pressure gas gathering, multi-well heating at the same time, throttling and pressure reduction, and natural gas heating is often required in the process of mining, transportation and use of natural gas, so natural gas heating furnaces are used in natural gas transportation As an indispensable important equipment in the system, the safe use and heat transfer efficiency of the heating furnace directly affect the safe and stable production of natural gas. Natural gas contains hydrates, hydrocarbons with small molecules, carbon dioxide and hydrogen sulfide molecules, etc. When the pressure and temperature conditions change during heating, scales will be deposited on the inner surface of the heating furnace pipe and the end fac...

AI Technical Summary

Problems solved by technology

Natural gas contains hydrates, hydrocarbons with small molecules, carbon dioxide and hydrogen sulfide molecules, etc. When the pressure and temperature conditions change during heating, scales will be deposited on the inner surface of the heating furnace pipe and the end surface of the smoke pipe, which will affect the heat dissipation. transmission efficiency, and even cause accidents in severe cases

At present, the commonly used descaling methods are chemical cleaning method and artificial vibration method, but the chemical method is expensive, corrodes the pipeline, pollutes the environment, and the artificial vibration method is time-consuming and laborious, which cannot meet the requirements of environmental protection, safety, economy and good technology, and Most pipe robots are only suitable for cleaning straight pipes, and cannot clean well for situations such as natural gas heating furnaces with shrimp bends and end faces of smoke pipes
