In contrast to the prior art, the vehicle carrier of a vehicle crane basically employs an integrated frame, while the crane assembly is mounted on the frame. When the crane is in small tonnage, the moment is small, the gravity center is not high as a whole, but when the crane is in large tonnage or ultra-large tonnage, the lifting moment becomes larger, wherein the moment arm is longer, the whole gravity center of the crane is seriously moved upwards, the whole gravity center is severely limited in the movement process, and the risks such as side turning and the like are easily generated. Especially internationally, the maximum lifting of the traditional crane is generally about 1200T, but China is currently in the leading position in the world, and the maximum lifting has been developed to be 2000T, 2200T and 2400T.2600T, but because of the limitation of the frame of the crane, the center of gravity of the crane is higher, so that the crane has a certain danger in the running process, and the maximum hoisting is required to be further enhanced, so that the consideration of how to lower the center of gravity of the whole crane is needed. In the utility model, the crane assembly is partially installed between the axial hydraulic power module vehicles 1 and is not installed on the load vehicle any more, so that the installation height of the crane assembly is effectively reduced, and the crane assembly is the first technical means for lowering the center of gravity. Along with the lifting of the hydraulic suspension system of the axis hydraulic power module vehicle 1, the crane assembly part can be integrally lowered until the crane assembly part is close to the ground, and the hydraulic power module vehicle is a second technical means for lowering the center of gravity. The gravity center of the whole crane can be effectively lowered, and the maximum crane can be further lifted.

The hydraulic module vehicle assembly further comprises a power module PPU connected to the end of one of the axis hydraulic power module vehicles 1 or integrated in the crane assembly. The power module PPU can be independently designed, and the power part of the crane can be used as the power module PPU to integrate the power module PPU. The power module PPU includes an engine, a hydraulic pump and a hydraulic oil tank, and is mainly used for driving the axial hydraulic power module vehicle 1 to walk, supporting a suspension system, providing hydraulic steering and the like, and the hydraulic power system of the power structure of the axial hydraulic power module vehicle 1 is a structure which is more common for large-piece transportation, and will not be repeated here.

A longitudinal splicing cable and a longitudinal splicing hydraulic pipeline are arranged between the axes of the two adjacent axis hydraulic power module vehicles 1. The cables and the longitudinal hydraulic pipelines are mainly used for transmitting hydraulic signals and hydraulic oil.

The two sides of the crane base 2 are respectively provided with a connecting plate 3 which is matched with the docking mechanism, and a plurality of connecting bolt holes are arranged on the connecting plates 3. The multiple axis hydraulic power module cars 1 are mutually spliced to form at least two multi-axis hydraulic axis cars, the multi-axis hydraulic axis cars are respectively connected to the connecting plates 3 on two sides of the crane base 2, and the height of the frame 5 of the multi-axis hydraulic axis car is flush with the bottom of the crane base 2. Even further, the height of the crane chassis can be made lower than the height of the axle carriage frame.

The multi-axis hydraulic axis vehicle is connected to the power modules PPU, respectively. Each axis hydraulic power module car 1 is provided with a hydraulic brake assembly. The traditional axis hydraulic power module vehicle is low in speed and is mainly stopped by the disappearance of hydraulic driving force. The hydraulic braking component is newly added in the application, and functions such as parking braking can be completed.

The composition of the axis car can be spliced arbitrarily according to the requirement, for example, an ultra-large crane with a lifting weight of more than 2000T can be used for load sharing by adopting an 8-axis car. For example, in the present utility model, it may be divided into two axis vehicles in the form of front 5-axis and rear 3-axis, that is, the front axis vehicle is composed of 5-axis hydraulic power module vehicles 1, and the rear axis vehicle is composed of 3-axis hydraulic power module vehicles 1. And the device can be divided into a scheme of front 4 shafts, rear 4 shafts and the like according to specific use disclosure, and the whole structure is more flexible and reliable. The two multi-axis vehicles are connected in a longitudinal splicing mode. It can of course also be spliced in other ways, such as a 7-axis car.

Of course, the hydraulic power module vehicle of the axial vehicle used in the application can also adopt a transverse splicing mode, and in this mode, the axial vehicle is subjected to transverse widening treatment. The chassis of the crane is arranged between the left and right 4-axis vehicles in a mode of the left and right 4-axis vehicles. And the articulated plug connector and a plurality of connecting bolts are used for fixedly connecting. In the technical field of axis vehicles, how to realize the connection between axis vehicles belongs to the technology known to those skilled in the art, and the applicant does not repeat the description here.

In practical use, in fig. 1-2, the power module PPU is integrated into the crane assembly, and no additional power module is required. As shown in fig. 1, a front vehicle is connected by 5 axis hydraulic power module vehicles 1 to form a front axis vehicle, a rear vehicle is connected by 3 axis hydraulic power module vehicles 1 to form a rear axis vehicle, a power system adopts a water-cooled turbo-charged engine of Hua-chai 330KW, and other engines can be adopted as power sources of course. And integrating the power module PPU into the lifting assembly. The jack-up subassembly is connected between front and back axis car, and the hoist base 2 bottom among the jack-up subassembly flushes with the frame height of axis car, compares with traditional automobile crane, and the application provides a self-walking ultra-low gravity center hydraulic module automobile crane has reduced the installation height on hoist chassis, installs it between the axis car, need not to install hoist subassembly on vehicle platform again. As shown in FIG. 2, in the second state, the height of the frames of the two multi-axis vehicles is controlled and further reduced by the hydraulic lifting system, the bottom of the chassis of the crane is flush with the height of the frames of the multi-axis vehicles, and when the frames of the axis vehicles descend along with the hydraulic lifting system, the height of the chassis of the crane also descends, so that the height of the lifting assembly descends integrally, and the whole platform is closer to the ground. As shown in the figure, the total lifting travel of the whole platform is 600mm, so that the gravity center of the whole lifting assembly part is effectively moved downwards, and the gravity center height is reduced for the second time in the working process. The overall lower center of gravity will be able to give further lifting space for the maximum hoisting weight of the truck crane.

As shown in fig. 3, the power module PPU is separately integrated, and is disposed at an end of one of the multi-axis vehicles, and the power module PPU is used as a separate component.
