Background
Along with the development of road construction and modern management, the requirements of people on life quality and environmental conditions are higher and higher, and the requirements on living environment and sanitary conditions are also higher and higher, so that the cleaning of roads becomes a necessary work every day in order to improve the living environment of residents, reduce road pollution and guarantee the health of people. The cleaning vehicle is a widely used cleaning vehicle in road cleaning operation, and compared with the traditional cleaning vehicle operation, the cleaning vehicle combining vacuum dust collection and wet dust removal can effectively avoid secondary dust pollution.
The tank body of the existing cleaning vehicle is more common that a clean water tank and a sewage tank are arranged in the same tank body, and a vertical partition plate and an inclined partition plate are arranged in the tank body to divide an inner cavity of the tank body into the clean water tank with an L-shaped cross section and the trapezoidal sewage tank.
In order to enhance the strength of the tank body of the cleaning vehicle, a plurality of upright columns are inevitably arranged on the two side plates, and the common upright columns are closely attached to the inner sides of the side plates. The stand column and the side plate are connected, no matter the stand column is installed firstly or the side plate is installed firstly, the joint surface between the stand column and the side plate cannot be welded and sealed completely, a communicating channel between the sewage tank and the clean water tank can be formed between the joint surfaces, the seal between the two tanks can be damaged, and namely the sewage of the sewage tank on the upper portion of the tank body can flow into the clean water tank on the lower portion along the joint surface.
If the sealing is to be realized, the gaps on the two sides of the connecting surface can be completely sealed and welded up and down, the welding points of the junction part of the inclined partition plate and the upright column are sealed, the upright column is generally 2-3 m long, the welding workload is too large, leakage points are easily formed, and the phenomenon of mutual invasion of sewage and clean water can exist.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the welding method of the upright post of the tank body, which has simple structure and convenient welding, completely isolates the clean water tank and the sewage tank in the tank body by welding the upright post, the partition plate and the side plate, and avoids mutual invasion between clean water and sewage.
