Automatic spraying machine for inner wall and outer wall of steel pipe

Abstract

The invention discloses an automatic spraying machine for the inner wall and the outer wall of a steel pipe, and belongs to the field of steel pipe spraying equipment. The automatic spraying machine comprises an inner wall spraying mechanism, an outer wall spraying mechanism, an operation table and a rotating mechanism, wherein the inner wall spraying mechanism comprises a first spraying assembly,a second spraying assembly and a material moving assembly; the first spraying assembly and the second spraying assembly comprise an extending and feeding component and a rotating and spraying component; the material moving assembly comprises a lifting component, a material moving plate and a material moving component; and the lifting component is arranged at the top of the material moving plate.According to the automatic spraying machine disclosed by the invention, the inner wall spraying mechanism can extend to the inner part of the steel pipe and automatically perform the operation of uniform spraying on the inner wall of the steel pipe, the situation that the local inner wall of the steel pipe is not sprayed is avoided; and the operation of spraying can be automatically performed on the outer wall of the steel pipe through the outer wall spraying mechanism, so that the automation degree is high, and the situation that a worker manually performs the operation of spraying on the outer wall of the steel pipe is not needed.

Description

technical field [0001] The invention relates to the field of steel pipe spraying equipment, in particular to an automatic spraying machine for inner and outer walls of steel pipes. Background technique [0002] Traditional finished steel pipes are usually formed by cold rolling, and the inner and outer walls of cold rolling are generally not sprayed with paint. In construction projects, it takes about 2-3 years from the beginning to the completion. In this way, steel pipes It is easy to rust and rot outdoors in the wind, sun and rain, which greatly shortens the service life of the steel pipe. In order to improve the antirust ability of the steel pipe, the current method is to manually spray the inner and outer walls of the steel pipe. The traditional manual spraying The labor intensity of the way is big, brings bigger labor load for worker, and it is difficult to carry out spraying operation to the inner wall of pipeline manually. [0003] The invention patent No. CN10300...
