Trackless hydraulic self-climbing formwork system and construction process thereof
The trackless hydraulic self-climbing formwork system comprises a climbing frame and a climbing formwork, a climbing rail is arranged on the climbing frame, the climbing rail is driven by a hydraulic oil cylinder to move upwards, a first hydraulic control one-way valve and a second hydraulic control one-way valve are installed on the hydraulic oil cylinder, the hydraulic oil cylinder comprises a first valve cavity and a second valve cavity, and a pilot rod is arranged in the first valve cavity; the first valve cavity is divided into a first cavity and a second cavity by the partition plate; the first hydraulic control one-way valve is provided with a first oil port, a second oil port and a first working oil port, wherein the first oil port and the second oil port communicate with the first cavity and the second cavity, and the first working oil port communicates with the second valve cavity and the rodless cavity. A valve sleeve of the second hydraulic control one-way valve is provided with a third oil port, a fourth oil port and a second working oil port, wherein the third oil port and the fourth oil port are communicated with the first cavity and the second cavity, the second working oil port is communicated with the rod cavity and the second valve cavity, and the third oil port and the fourth oil port are both communicated with an external hydraulic system. By arranging the first hydraulic control one-way valve and the second hydraulic control one-way valve, when the hydraulic rubber pipe is broken or power failure occurs, the pressure of hydraulic oil in the hydraulic oil cylinder is kept constant, and the hydraulic self-climbing formwork system is prevented from falling off.
本发明公开了无轨液压自爬模系统，包括爬架和爬升模板，爬架上设有爬轨，爬轨在液压油缸的驱动下上行，液压油缸上安装有液控单向阀一和液控单向阀二，其包括第一阀腔和第二阀腔，第一阀腔内设有先导杆，其将第一阀腔阻隔成第一腔室和第二腔室；液控单向阀一上设置与第一腔室和第二腔室连通的油口一和油口二、连通第二阀腔和无杆腔的工作油口一；液控单向阀二的阀套上设置有与第一腔室和第二腔室连通的油口三和油口四、连通有杆腔和第二阀腔的工作油口二，所述油口三和油口四均连通外部的液压系统。本发明通过设置液控单向阀一和液控单向阀二，在液压胶管破裂或发生断电故障时，保持液压油缸内液压油压力恒定，避免液压自爬模系统坠落。
