Problems solved by technology

Conventional internal anti-corrosion measures for penstocks are manual spraying: place the penstock horizontally on the roller frame, rely on the roller frame to rotate, and use manual spraying, the spraying efficiency is low, the manual spraying is uneven, and the spraying quality is difficult to control
Spraying not only produces a lot of waste of labor and materials, but also has high safety and quality risks in the construction process and slow progress

Abstract

The invention discloses a device for spraying the inner wall of a pressure steel pipe. The device comprises: a base and a spraying mechanism; the bottom of the base is provided with a walking mechanism; the spraying mechanism comprises a main supporting frame, a spraying support and a spraying device; the main support frame comprises a fixed frame and a telescopic frame; the spraying support comprises a vertical support extending upwards along the telescopic frame and a horizontal support perpendicular to the vertical support; and the spraying device comprises a rotating shaft, a plurality of spraying gun nozzles, large-diameter spraying telescopic rods and a paint spraying tank, wherein the spraying gun nozzles and the large-diameter spraying telescopic rods are arranged in a matched mode. The rotating shaft penetrates through the paint spraying tank in a sealing mode and drives the paint spraying tank to rotate, the large-diameter spraying telescopic rods are arranged on the radial section of the pressure steel pipe at intervals and communicate with the paint spraying tank, and the spraying gun nozzles just spray the inner wall of the pressure steel pipe. According to the device for spraying the inner wall of the pressure steel pipe, manual spraying can be replaced, spraying engineering automation is achieved, the spraying quality is effectively controlled, and safety in the construction process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pressure steel pipe spraying. More specifically, the present invention relates to a device for spraying the inner wall of a penstock. Background technique [0002] The penstock is a steel pipeline that forcibly transports extremely high pressure water flow. The penstock is a closed environment, and the intensity of the water flow can be controlled through the switch of the water gate or the fence. In modern times, penstocks are often used in fields such as hydropower generation, oil transportation, and sewage treatment. Conventional internal anti-corrosion measures for penstocks are all manual spraying methods: place the penstock horizontally on the roller frame, rely on the roller frame to rotate, and use manual spraying, the spraying efficiency is low, the manual spraying is uneven, and the spraying quality is difficult to control. Spraying not only produces a lot of waste of labor and materials, but ...
