The invention relates to the technical field of service platforms, in particular to an automatic leveling and emergency descending hydraulic control system for a service platform. An oil outlet A of a first control valve is communicated with a rod cavity of a left supporting oil cylinder and a pilot port of a first balance valve, and an oil outlet B of the first control valve is communicated with an oil outlet of the first balance valve; an oil outlet A of the second control valve is communicated with a rod cavity of the right supporting oil cylinder and a pilot port of the second balance valve, and a rodless cavity of the right supporting oil cylinder is communicated with an oil inlet of the second balance valve and an oil inlet B of the one-way valve set. And an oil outlet of the one-way valve group is communicated with an oil inlet of the ball valve. Automatic leveling of the service platform is achieved in a hydraulic control mode, operators in the service platform can control the service platform to descend under the emergency condition, operation is simple and reasonable, and construction safety and comfort are effectively improved.

    本发明涉及服务平台技术领域,具体涉及一种服务平台自动调平及应急下降液压控制系统。本发明的第一控制阀的出油口A与左支撑油缸的有杆腔和第一平衡阀的先导口相连通,所述第一控制阀的出油口B与第一平衡阀的出油口相连通;第二控制阀的出油口A与右支撑油缸的有杆腔和第二平衡阀的先导口相连通,所述右支撑油缸的无杆腔与第二平衡阀的进油口和单向阀组的进油口B相连通;所述单向阀组的出油口与球阀的进油口相连通。本发明利用液压控制的方式实现服务平台的自动调平,且在紧急情况下可由服务平台内部作业人员控制服务平台下降,操作简单合理,有效地提高了施工的安全性和舒适性。
