The invention discloses an anti-rust device for a vehicle tubular structural member. The anti-rust device comprises a plurality of turning joints, wherein the plurality of turning joints communicate to form a runner, the one end of which is closed while the other end of which is opened, and adjacent two turning joints are connected through a rubber soft joint; an injection hole is formed in each rubber soft joint; a through hole formed by a straight section and a transition section is formed in each nozzle, the small inner diameter end and the straight section of the transition section communicate, and the large inner diameter end of the transition section communicates to each injection hole. Anti-corrosion spraying on the inner wall of a straight steel tube can be carried out by means ofthe rubber soft joints between two adjacent turning joints. The inner walls of the steel tubes with certain bending amplitudes and various corners can be sprayed, so that the application range of a spray gun head is improved. Similarly, the nozzles among the plurality of turning joints can spray the inner wall of the steel tube repeatedly for many times according to the moving direction thereof toguarantee that the anti-corrosion coating is continuous and intact in the inner wall of the steel tube, so that the stable performance of the steel tube in the using process is guaranteed.
Description
technical field [0001] The invention relates to the field of steel pipe anticorrosion, in particular to an antirust device for tubular structural parts of vehicles. Background technique [0002] During the operation of long-distance pipelines, the presence of various corrosive substances in the transport medium causes corrosion of the inner wall of the pipeline, which in turn causes accidents such as perforation and leakage, resulting in problems such as production stoppage and environmental pollution. Media flow is inefficient. In the prior art, when carrying out anticorrosion treatment on the inner wall of steel pipes, manual operation is generally used as the main means to carry out open sand blasting and extrusion coating anticorrosion coating on steel pipes to achieve the purpose of prolonging the service life of steel pipes. However, when the inner wall of the steel pipe is coated, the anti-corrosion layer formed is unevenly dispersed, and due to the length of the pip...
