Pipeline inner wall spraying device

Abstract

The invention relates to a pipeline inner wall spraying device. The pipeline inner wall spraying device comprises prepositioned stators, postpositioned stators and a support column, wherein one end of the support column is fixedly connected with one ends of the prepositioned stators, the other end of the support column is fixedly connected with one ends of the prepositioned stators, spray heads are arranged at the other ends of the prepositioned stators, at least three groups of first landing legs are uniformly distributed on the circumferential surfaces of the prepositioned stators, first motors for driving the spray heads to rotate are arranged in the prepositioned stators, spray pipe adaptors are arranged at the other ends of the postpositioned stators, at least three groups of second landing legs are uniformly distributed on the circumferential surfaces of the postpositioned stators, the spray heads are connected with the spray pipe adaptors by guide pipes, and rolling wheels and second motors for driving the rolling wheels are arranged at the tail ends of the second landing legs. According to the pipeline inner wall spraying device, at least three prepositioned stators and the postpositioned stators with driving rolling wheels are uniformly distributed at two ends of the support column respectively, so that the spraying device can walk flexibly.

Description

technical field [0001] The invention relates to a spray coating device, in particular to a pipeline inner wall spray coating device. Background technique [0002] Sandblasting and gluing is a common means of industrial surface treatment. In the past, sandblasting and gluing on the inside of rectangular pipes or circular pipes were manually entered, manually operated, or operated by feeling from the outside. It is impossible to observe the internal working conditions and it is easy to cause leakage. Paint, overpaint. [0003] The existing Chinese patent 200820033683.0 proposes a large-diameter gas transmission steel pipe inner coating spraying equipment, which mainly includes a V-shaped support frame, a trolley and trolley driving and traveling devices, and a spraying device. Wherein, the spraying device includes a nozzle, a telescopic frame, a paint pump, a paint storage tank, and the like. Install the nozzle on the telescopic frame, and adjust the position of the nozzle b...

Also, Chinese patent 201110202843.6 proposes a pipe diameter self-adaptive inner wall spraying equipment for large-diameter steel pipes. These two spraying devices are all provided with a device similar to a guide rail to provide a walking track for the trolley, so that the trolley cannot walk freely. The length of the spray will be affected by the track
