[0002] At present, with the increasing demand for the exploitation of unconventional resources such as shale gas, fracturing technology has been widely used. Fracturing is a method of using hydraulic force to form cracks in oil and gas layers, thereby facilitating the exploitation and collection of resources; in the actual application of fracturing, it is generally necessary to deploy a fracturing truck with a fixed fracturing pump on site to squeeze high-pressure and high-volume working fluid into the oil and gas layers.

[0003] However, existing fracturing trucks often directly fix equipment such as fracturing pumps on the vehicle body by welding or other means, and the fracturing truck cannot be moved during operation. This has a high production cost for the equipment manufacturer and is also difficult to maintain in the later stage. In some existing technologies, each device is transported to the site independently, placed on the pre-treated ground and then connected through a corresponding mechanical structure, which increases the difficulty of early construction on site, and the noise generated by the equipment directly exposed on site is relatively large, which also directly affects the working environment of the on-site staff.
