Special car supporting balance system

Abstract

The invention relates to a special car supporting balance system. A first wingspan system and a second wingspan system in the wingspan systems are arranged in parallel front and back, and the length of the two wingspan systems after shrinkage is matched with the width of a carriage; each wingspan system is divided into a fixed cavity and a wingspan section, wherein the wingspan section does stretchable motion in the fixed cavity, supporting systems are arranged in the vertical direction of the end of the wingspan section and are divided into the first supporting system and the second supporting system which correspond to the first wingspan system and the second wingspan system correspondingly, the ends of the fixed cavities of the first wingspan system and the second wingspan system are inwards provided with opening grooves of U-shaped structures, the opening grooves vertically penetrate the first supporting system and the second supporting system and contain the first supporting system and the second supporting system after shrinkage, and therefore the wingspan area is increased; and the opening grooves are formed in the ends of the fixed cavities, and the first supporting systemand the second supporting system are contained after shrinkage, due to the fact that the length of a hydraulic cylinder is increased after unfolding, and therefore the stress area is increased withina limited scope.

Description

technical field [0001] The invention relates to a support system for a special vehicle, in particular to a support and balance system for a special vehicle. Background technique [0002] Special-purpose cranes and truck-mounted cranes have been widely used. In order to increase stability, it must have a stable center of gravity. Therefore, the method of pulling wing hydraulic support legs is used to expand the force-bearing area and stabilize the center of gravity. [0003] However, each model has a size and tonnage limit in the announcement. The purpose is to ensure the safety and quality of the vehicle. When the size is limited, its size cannot be changed at will. It can only be modified within the original range, but it is affected by the hydraulic system. , It is impossible for the hydraulic system to be made into a multi-stage extended wing. At the same time, the multi-stage extended wing will also lead to a reduction in strength and an ultra-wide width, which will dire...

[0003] However, each model has a size and tonnage limit in the announcement. The purpose is to ensure the safety and quality of the vehicle. When the size is limited, its size cannot be changed at will. It can only be modified within the original range, but it is affected by the hydraulic system. , the hydraulic system cannot be made into a multi-stage extended wing, and the multi-stage extended wing will also lead to a reduction in strength and an ultra-wide width, which will directly affect the car announcement and its own quality and safety hazards
