The invention discloses a hydraulic steering system, high-altitude operation equipment and a steering control method, and relates to the technical field of high-altitude operation devices. The braking double-speed control valve group is provided with a braking control valve for controlling the braking of the steering wheel; an oil source power assembly; one end of the first connecting oil way is connected to the oil inlet end, connected with the oil source power assembly, in the axle control valve set, and the other end of the first connecting oil way is connected to the oil inlet end of the brake control valve; when the oil source power assembly conveys hydraulic oil to the axle control valve group, the hydraulic oil entering the axle control valve group is divided into one path to the first connecting oil path, so that the brake control valve controls the steering wheel to relieve braking. According to the hydraulic steering system, the friction force between the steering wheels and the ground in the steering process can be effectively reduced, the acting force borne by the steering oil cylinder is reduced when the steering wheels steer, and the steering response speed and synchronism of the left steering wheel and the right steering wheel are improved.

    本发明公开了一种液压转向系统、高空作业设备、转向控制方法,涉及高空作业装置技术领域,液压转向系统包括:轮轴控制阀组,用于控制转向轮转向;制动双速控制阀组,设置有用于控制转向轮制动的制动控制阀;油源动力组件;第一连接油路,其一端连接于轮轴控制阀组中与油源动力组件连接的进油端,另一端连接于制动控制阀的进油端;油源动力组件向轮轴控制阀组输送液压油时,进入轮轴控制阀组的液压油分一路至第一连接油路,以使制动控制阀控制转向轮解除制动。本发明中的液压转向系统可有效减小转向轮在转向过程中与地面之间的摩擦力,使转向轮在转向时转向油缸所受作用力减小,提高左侧转向轮与右侧转向轮转向的响应速度和同步性。
