Technical Field

The invention belongs to the field of cranes, in particular relates to a turning stabilizing device of a high-speed mobile crane, and relates to the technology of the turning stabilizing device of the crane.

Background

With the continuous development of science and technology, a mobile crane generally adopts a crane carrier provided with a mechanical rod Steering system and an Electro-Hydraulic Power Steering (EHPS) system to realize the mobile operation function of the mobile crane, and meanwhile, the mobile crane (for example, a five-axis or more all-terrain crane) is widely applied to various scenes and various industry fields due to the characteristic that the mobile crane can movably carry out heavy object hoisting work. Therefore, the mobile crane is inevitably not arranged to a work site with a narrow space for hoisting operation, wherein the turning radius of the crane carrier when moving in the work site with the narrow space is an extremely important index for influencing the passing efficiency of the crane in the work site with the narrow space.

When the existing crane carrier moves in a work place with a narrow space, in order to avoid the phenomenon of abnormal abrasion of tires, the turning radius of the crane carrier during turning is usually regulated and controlled by adopting an all-wheel turning mode meeting Ackerman's theorem. However, the working performance of the EHPS system cannot be fully adjusted in the all-wheel steering mode, so that the turning radius of the crane carrier expressed in the all-wheel steering mode is still larger than the spatial range of the working site, and thus the passing efficiency of the crane in the working site is not high, the turning is difficult, and the danger degree is high; therefore, a new design scheme needs to be proposed.
