Coating spraying device for interior of thin and long pipeline

Abstract

The invention relates to a coating spraying device for the interior of a thin and long pipeline. The coating spraying device comprises a walking mechanism, a spraying mechanism and a camera device. The walking mechanism comprises a first motor, a first speed reducer, a chain transmission mechanism, a runner and two supporting plates provided with spring control supporting wheels. Multiple connecting rods are arranged between the two supporting plates, and the spring control supporting wheels are installed on the supporting plates through spring control supporting wheel rods. A chain in the chain transmission mechanism is wound around the runner, and the chain is connected with the supporting plates through a buckle structure. The spraying mechanism comprises a coating transmission shaft, arotating nozzle, a material conveying pipe and a material disc. The coating transmission shaft is in transmission connection with an output shaft of a second speed reducer. The coating transmission shaft is of a hollow structure, and a small hole is formed in the shaft wall of the coating transmission shaft. The material disc is installed at the head portion of the coating transmission shaft, andthe rotating nozzle is installed on the material disc. The camera device comprises a camera and an illumination lamp. Compared with the prior art, the coating spraying device can be suitable for thinand long pipelines with the pipeline inner diameter being 100 mm to 600 mm, and the spraying conditions in the pipelines can be observed conveniently.

Description

[technical field] [0001] The invention relates to the technical field of paint spraying in pipelines, in particular to a paint spraying device in elongated pipelines. [Background technique] [0002] At present, the existing spraying devices in the market are often suitable for pipes with an inner diameter greater than 600mm, and it is difficult to work when encountering a pipe with an inner diameter smaller than 600mm. Moreover, manual operation inside the slender pipe is time-consuming and laborious, and it is impossible to directly observe the spraying situation inside the pipe. Therefore, it will be of great significance to provide a spraying device that can be flexibly adapted to different inner diameters and observe internal conditions. [Content of the invention] [0003] The purpose of the present invention is to solve the above-mentioned deficiencies and provide a kind of paint spraying device in the slender pipeline, which can be applied to the slender pipeline wit...

[0002] At present, the existing spraying devices in the market are often suitable for pipes with an inner diameter greater than 600mm. When encountering a pipe with an inner diameter smaller than 600mm, it is difficult to work

Moreover, manual operation inside the slender pipe is time-consuming and laborious, and it is impossible to directly observe the spraying situation inside the pipe. Therefore, it will be very important to provide a spraying device that can be flexibly applied to different inner diameters and observe the internal conditions.
