Spraying device for uniformly spraying inner wall of pipeline

Abstract

The invention discloses a spraying device for uniformly spraying the inner wall of a pipeline. The spraying device comprises a base and a coating pipe, wherein a connecting shaft is arranged in the base, the two ends of the connecting shaft are connected with first rollers in a rotating mode, a first gear is rotationally connected to the connecting shaft at the rear side, a protective shell is arranged on the surface of the base, a motor is arranged in the protective shell, the motor is rotationally connected with a motor shaft, the motor shaft is rotationally connected with a second gear, thesecond gear is connected with a first gear in a meshed mode, shock absorbers are arranged on the periphery of the protective shell, and the tops of the shock absorbers are connected with the bottom of the shell. The spraying device for uniformly spraying the inner wall of the pipeline is provided with the base, the first rollers, the motor, telescopic connecting rods, telescopic supports, springs, second rollers, a spraying disc and a nozzle, so that the self-walking capability is provided for the device, the stability of the device in moving in the pipeline is improved, uniform spraying of the interior of the pipeline is ensured, and the using convenience is improved.

Description

technical field [0001] The invention relates to the technical field of spraying devices, in particular to a spraying device for uniform spraying on the inner wall of a pipeline. Background technique [0002] The spraying device refers to a device that disperses the paint into uniform and fine droplets by means of pressure or centrifugal force and applies it to the surface of the object to be coated. Some pipes, especially metal pipes, are prone to overlook due to their own characteristics and working environment. It is usually necessary to spray protective paint, so a spraying device for uniform spraying of the inner wall of the pipe is required. [0003] Existing spraying devices are usually fixed and have a large volume. When it is necessary to spray the interior of some pipeline materials, it is inconvenient to use, and the traditional small pipeline interior spraying device itself lacks the ability to move, so it is not enough to use Convenience, in view of the above pr...
