[0030] As shown in Figure 12 , a hydraulic system is used as the power source of each actuator, driven by a hydraulic cylinder, to realize the lifting and erecting of super large loads; through the control of three degrees of freedom of the main frame 4, the folding arm 8 and the lifting hook 10, the super large load is lifted and filled from the ground to the vehicle body, and can be unloaded to the ground automatically, reducing the auxiliary hoisting equipment, avoiding the danger of high-altitude operation in the hoisting process, improving the stability, universality and space utilization of the filling equipment, and reducing the energy consumption. In practice, based on the control system 13, the filling and erecting mechanism is generally automatically controlled by using main control combination, handheld controller and sensor, software to realize automatic filling and unloading, and improve the automation degree of the product.

[0031] The present application is to improve the autonomy, stability, universality and loading speed of heavy vehicle loading and transportation, to adapt to the transportation and handling of super large load, and mainly solves the following technical problems: a) single vehicle operation can be realized to reduce auxiliary handling equipment; b) the operation of loading and unloading is simple and convenient to reduce the number of workers; c) the loading and unloading process is as smooth as possible to avoid the influence of running speed and wind load and other external environment during loading and unloading, reduce the operation difficulty and improve the stability; d) different structural forms of load handling and transportation can be realized to improve the universality of the equipment; e) the equipment should realize automatic control to improve the operability of the equipment and reduce the operation intensity of the workers.

Specifically, the main frame is hinged to the tail beam of the chassis through a rotating base, and the folding arm is driven by the overturning oil cylinder to form a "main frame-folding arm-lifting hook" three-stage linkage structure. The folding arm is telescopic, and the lifting hook is connected to a universal bracket to realize the whole process of load grabbing, lifting, overturning and placing.

This design decomposes the load gravity into axial pressure and rotary torque, and reduces the single-point stress concentration.

[0034] Through the combination of the overturning oil cylinder, the connecting hinge and the folding arm, the action stroke amplification is realized, and the layout space and the energy required for driving the load are effectively saved.
