Urban underground pipeline spraying anti-corrosion device

Abstract

The invention discloses an urban underground pipeline spraying anti-corrosion device. The urban underground pipeline spraying anti-corrosion device comprises a shell; a plurality of supporting legs are installed at the bottom end of the shell; the upper end of the shell is fixedly connected with a vertically-arranged feeding pipe; the feeding pipe is rotatably communicated with a transfer box, andthe transfer box is of a hollow and sealed structure; the transfer box is fixedly connected to the inner wall of the shell and rotatably communicated with a spraying pipe; and the end, away from thetransfer box, of the spraying pipe extends out of the shell and is connected with a reciprocating driving mechanism through a transmission mechanism, wherein the reciprocating driving mechanism drivesthe spraying pipe to rotate in a reciprocating mode. According to the urban underground pipeline spraying anti-corrosion device provided by the invention, the reciprocating driving mechanism is arranged, power is provided through an air cylinder, reciprocating motion of a center gear is achieved through mutual cooperation of a side edge gear, a sector gear and a rack, and therefore the transmission mechanism drives the spraying pipe to do reciprocating motion finally, reciprocating spraying of a spraying head is achieved, the effect is better, the coverage area is larger, and meanwhile spraying dead corners can be avoided.

Description

technical field [0001] The invention relates to the technical field of pipeline spraying, in particular to a spraying anticorrosion device for urban underground pipelines. Background technique [0002] Urban underground pipelines refer to pipelines and ancillary facilities for water supply, drainage, gas, heat, electricity, communications, radio and television, industry, etc. within the city, and are important infrastructure and "lifelines" to ensure urban operation. In recent years, accidents such as urban waterlogging, road subsidence, and pipeline bursts caused by problems in underground pipe networks have become more frequent in various places. Therefore, it is necessary to spray paint on underground pipes to increase their physical properties such as corrosion resistance. [0003] In the prior art, manual spraying or fixed spraying is usually used in the spraying of underground pipelines. The former is more labor-intensive and requires certain requirements for the exper...
