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.
本实施例提供的轮压均衡结构及起重机,涉及轮压均衡技术领域。旨在改善现有轮压均衡结构轮压均衡效果有限的问题。辅助车轮设置在轮架的中部;液压保压系统,液压保压系统包括恒压组件和液压缸,恒压组件用于对液压保压系统中的流体进行调节,以使液压缸的压力保持恒定;液压缸的两端分别连接轮架的中部和辅助车轮。起重机包括轮压均衡结构。采用液压保压系统,使辅助车轮的压力的始终恒定地控制在限制范围内,轮压恒定且可知,轮压均衡效果更好;同时辅助车轮设置在轮架的中部,不影响整机宽度,不影响起重机多机联合作业效率,同时规避空间限制的问题,具有降低单个车轮轮压的效果,改善了现有的轮压均衡结构均衡效果有限的问题。
