Description

Technical Field

[0001] The utility model relates to the technical field of production spraying of a sub-beam of a fracturing vehicle, in particular to a spraying device for processing the sub-beam. Background Art

[0002] Fracturing truck is a special vehicle used to inject high-pressure, large-volume fracturing fluid into the well, to open the formation and squeeze the proppant into the crack. It is mainly used for various fracturing operations in oil, gas and water wells, and can also be used for hydraulic sandblasting, high-pressure hydraulic coal mining in coal mines, and high-pressure hydraulic rust removal on ships. The equipment can perform stand-alone and online operations. It is mainly composed of a vehicle chassis, a platform engine, a platform transmission box, a fracturing pump, a manifold system, a lubrication system, a circuit system, a gas system and a hydraulic system.

[0003] Among them, the automobile sub-beam is the smaller and narrower beam on the top, also called the second beam, which needs to be sprayed during the production process to achieve corrosion protection.

[0004] Chinese patent announcement No. CN213494480U discloses an automatic spraying tool for automobile anti-collision beams. The anti-collision beams of the same internal strength model can be fixed by an elastic locking mechanism, and the elastic locking mechanism is driven to rotate by a one-way driving device, without the need for manual flipping, thereby improving the painting effect; at the same time, the threaded arm of the lifting device is driven to rotate by a two-way driving device, so that the slider connected to the threaded arm through the threaded hole can move up and down under the action of the rotating threaded arm and the support of the sliding arm, so that the nozzle installed on the slider can realize the rotational painting of the anti-collision beam, thereby realizing automatic painting of the anti-collision beam.

[0005] However, compared with the existing technology and comparative documents, the existing sub-beam has a rectangular structure during the spraying process, and in order to improve the spraying efficiency, an atomized spraying method is adopted. When the sub-beam is fully painted and turned over, the distance between the spray gun and the sub-beam will change, causing the paint mist to splash or fall on the workpiece surface and the paint film to form a virtual mist, thereby reducing the spraying quality.
