Abstract

The embodiment of the invention provides a wheel pressure balance structure and a crane, and relates to the technical field of wheel pressure balance. The problem that an existing wheel pressure balance structure is limited in wheel pressure balance effect is solved. The wheel pressure balance structure comprises a wheel frame, auxiliary wheels and a hydraulic pressure maintaining system, the auxiliary wheels are arranged in the middle of the wheel frame, the hydraulic pressure maintaining system comprises a constant pressure assembly and a hydraulic cylinder, the constant pressure assembly isused for adjusting fluid in the hydraulic pressure maintaining system so as to enable pressure of the hydraulic cylinder to be kept constant, the two ends of the hydraulic cylinder are connected withthe middle of the wheel frame and the auxiliary wheels, and the crane comprises the wheel pressure balance structure. Through the hydraulic pressure maintaining system, the pressure of the auxiliarywheels is always and constantly controlled within the limited range, the wheel pressure is constant and known, the wheel pressure balance effect is better, meanwhile, the auxiliary wheels are arrangedin the middle of the wheel frame, the whole machine width is not affected, the multi-unit combined work efficiency of the crane is not affected, meanwhile, the space limiting problem is solved, the effect of reducing the wheel pressure of the single wheel is achieved, and the problem that the existing wheel pressure balance structure is limited in balance effect is solved.

Description

technical field [0001] The invention relates to the technical field of wheel pressure equalization, in particular to a wheel pressure equalization structure and a crane. Background technique [0002] In the prior art, by dividing the wheels into several parts, and then reducing the distance between the wheels in each part, this can balance the wheel pressure of each group of trolleys or trolley groups under the same hinge shaft , but there is a problem of limited equilibrium effect. Contents of the invention [0003] The object of the present invention includes, for example, to provide a wheel pressure equalization structure, which can improve the problem of limited wheel pressure equalization effect of the existing wheel pressure equalization structure. [0004] The purpose of the present invention is also to provide a crane, which can improve the problem of limited wheel pressure equalization effect of the existing wheel pressure equalization structure. [0005] Embodi...
