The invention discloses a chassis floating hydraulic system and an aerial work platform, and belongs to the technical field of aerial work platforms. The chassis floating hydraulic system comprises a first floating oil cylinder, a second floating oil cylinder and a floating control valve, and a piston rod of the first floating oil cylinder is connected with a front axle of a chassis and used for controlling floating of a left front wheel; a piston rod of the second floating oil cylinder is connected with the front axle of the chassis and used for controlling floating of the right front wheel; and the first floating oil cylinder and the second floating oil cylinder communicate with an oil inlet way and an oil return way through the floating control valve, the floating control valve is configured to control stretching and retracting of the piston rod of the first floating oil cylinder and the piston rod of the second floating oil cylinder, and reversing of the floating control valve is controlled by swinging of a rear axle of the chassis. According to the chassis floating hydraulic system and the aerial work platform, full-time floating can be achieved, and the work efficiency is improved; and the operation safety can be ensured.
本发明公开了一种底盘浮动液压系统及高空作业平台,属于高空作业平台技术领域。该底盘浮动液压系统包括第一浮动油缸、第二浮动油缸和浮动控制阀,其中,第一浮动油缸的活塞杆与底盘的前桥连接,用于控制左前轮的浮动;第二浮动油缸的活塞杆与底盘的前桥连接,用于控制右前轮的浮动;第一浮动油缸和第二浮动油缸通过浮动控制阀与进油油路和回油油路连通,浮动控制阀被配置为控制第一浮动油缸的活塞杆和第二浮动油缸的活塞杆的伸缩,浮动控制阀的换向由底盘的后桥的摆动控制。该底盘浮动液压系统及高空作业平台能够实现全时浮动,提高了作业效率;且能够保证作业的安全性。
