High-pressure rotary spray gun

Abstract

The invention discloses a high-pressure rotary spray gun. The high-pressure rotary spray gun comprises a spray gun rod, retractable supporting wheels and a rotary sprayer, wherein the spray gun rod is provided with a hollow cavity, a high-pressure air connection port is formed in the tail of the spray gun rod, the retractable supporting wheels are fixedly arranged outside the spray gun rod, the rotary sprayer is mounted at the head of the spray gun rod through a bearing and is provided with three spray heads, of which the end parts are provided with identical bends, hollow cavities of the spray heads are communicated with the hollow cavity of the spray gun rod, and sealing gaskets are respectively arranged a junction between the rotary sprayer and the bearing and a junction between the bearing and the spray gun rod; each retractable supporting wheel consists of a supporting rod and a wheel, the length of each supporting rod is adjustable, one end of each supporting rod is connected onto the spray gun rod, and the other end of each supporting rod is connected with the corresponding wheel; a rope fixing ring is arranged at the most front end of the spray gun rod. The high-pressure rotary spray gun can conveniently move back and forth inside a pipeline, adjustable supporting wheels are applicable to cleaning operation of internal walls of pipelines of different pipe diameters, repeated cleaning can be carried out through pulling the spray gun back and forth, and thus, the aims of saving time, saving labor and guaranteeing processing quality are achieved.

Description

technical field [0001] The invention relates to a novel high-pressure rotary spray gun, in particular to a spray gun for cleaning the inner wall of a pipeline. Background technique [0002] In the field of purification and cleaning of the inner wall of the pipeline, when cleaning the inner wall of the pipeline, it is necessary to drill into the inside of the pipeline, or when cleaning a thinner pipeline, you can only put your hand into the pipeline and hold a high-pressure spray gun to clean the inner wall of the pipeline laboriously. This method is both laborious and uneven. , The cleaning is still not clean, so a portable and efficient equipment is needed to clean the inner wall of the pipeline. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a time-saving, labor-saving and easy-to-operate pipe inner wall cleaning device for the problems existing in the prior art. [0004] To solve this technical problem, the ...
