Combined pipeline washing and spraying robot

Abstract

The invention discloses a combined pipeline washing and spraying robot. The combined pipeline washing and spraying robot comprises a moving mechanism, a spraying mechanism and a milling mechanism, wherein the moving mechanism is arranged at the rear end of the whole device, wherein the moving mechanism comprises a driving motor, a worm and a worm gear; one end of the driving motor is fixedly connected to an intermediate shaft at the left side; the spraying mechanism comprises spraying guns which are arranged at equal intervals around the intermediate shaft and are rotated synchronous with theintermediate shaft; the milling mechanism is arranged at the right end of the whole device; the motor is arranged in a flexible mechanism; and one end of the motor is connected to the flexible mechanism through a spring. According to the combined pipeline washing and spraying robot, the moving mechanism mainly composed of the worm gear and the worm is capable of driving the whole device to move ina pipeline; and meanwhile, the milling mechanism is arranged at the front part of the whole device, and dirt on the inner wall of the pipeline can be removed by milling through a cutter; and moreover, a novel cutter coating is adopted, and the process of passivating processing can be avoided, so that the influence of toxic passivating liquid on surrounding environment is avoided, and as a result,the purpose of environmental protection is achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning equipment, in particular to a combined pipeline cleaning and spraying robot. Background technique [0002] As an efficient means of fluid and gas transportation, pipeline transportation is widely used in nuclear industry, petroleum and coal, and various aspects of society and people's livelihood. Due to the closed nature of the pipeline and the different sizes, it is very troublesome to detect flaws, repair and maintain, dredging, and spraying. [0003] At present, my country's pipeline cleaning methods mainly include physical and chemical methods. Physical methods include hammering and beating methods and high-pressure water jet cleaning methods. The first type is relatively labor-intensive, while the second type consumes a lot of clean water. After cleaning, a large amount of waste water will be discharged and the local vegetation will be destroyed. Chemical cleaning is a technology...
