Description

Technical Field

[0001] The utility model relates to the field of oilfield fracturing vehicles, in particular to a chassis of an oilfield fracturing vehicle. Background Art

[0002] Oilfield fracturing trucks are special vehicles used to inject high-pressure, large-volume fracturing fluid into wells to press the formations open and squeeze proppants into cracks. They are mainly used for various fracturing operations in oil, gas and water wells. They can also be used for hydraulic sandblasting, high-pressure hydraulic coal mining in coal mines, and high-pressure hydraulic rust removal on ships.

[0003] In the prior art, the oilfield fracturing truck adopts an 8×4 drive type and uses an ordinary truck frame structure. 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 are arranged on the frame. When working, the starting motor of the platform engine is driven by the power of the chassis engine to make the platform engine work. The power generated by the platform engine is transmitted to the power end of the fracturing pump through the hydraulic transmission box and the drive shaft to drive the fracturing pump to work. The fracturing fluid enters the fracturing pump from the suction manifold, is discharged from the high-pressure discharge pipe after being pressurized by the fracturing pump, and is injected into the well to carry out fracturing operations.

[0004] With the changes in the oilfield exploitation environment, oilfield fracturing trucks are required to have strong mobility and environmental adaptability, and to be more diversified in form and more complete in function. However, the frame structure strength of ordinary trucks is relatively low, which causes the following problems: on the one hand, it is difficult to add more upper equipment or large equipment to meet the needs of diversified functions; on the other hand, the road conditions in the oilfield exploitation environment are poor, and the vehicle is subject to strong bumps during driving, which exerts a large force on the frame and easily causes problems such as frame deformation. Fracturing trucks operate in this environment for a long time, and the low frame strength is bound to lead to problems such as short vehicle service life and many failures. Utility Model Content

[0005] In order to solve the technical problem of low frame strength of the oilfield fracturing truck chassis in the above-mentioned prior art, the utility model provides an oilfield fracturing truck chassis, whose frame has high strength and can carry a variety of large-scale upper equipment to meet multi-functional needs while extending the service life of the entire vehicle.
