The invention discloses a safe in-position system for a jacking cross beam of a tower crane. The device mainly comprises a standard section, the standard section is sleeved with a sleeve frame, the sleeve frame is connected with one end of an oil cylinder through a pin shaft, the other end of the oil cylinder is connected with a jacking cross beam through a pin shaft, a position switch K1 is installed at the position, close to the oil cylinder, of the upper end of the sleeve frame, and jacking cross beam pedals are installed at the two ends of the jacking cross beam. A position switch K2 and a position switch K3 are installed above the jacking beam pedal, the standard section comprises a standard section stand column, a standard section pedal is installed on the side face of the standard section stand column, a hydraulic station is fixedly installed on the sleeve frame, a bypass electromagnetic valve is installed on the hydraulic station, and a pressure switch K0 is arranged in a large cavity of the oil cylinder and sinks into the oil cylinder. The travel switch on the jacking cross beam is used for automatically identifying whether the position of the jacking cross beam is a safe position or not; when the jacking cross beam is located at the safe position, the hydraulic pump station can drive the hydraulic oil cylinder to conduct jacking operation. Otherwise, the jacking operation is interrupted, so that the jacking danger is avoided.
本发明公开了一种塔机顶升横梁安全就位系统。本发明主要包括标节,标节上套设有套架,套架通过销轴连接油缸的一端,油缸的另一端通过销轴连接有顶升横梁,套架的上端靠近油缸的位置安装有位置开关K1,顶升横梁的两端安装有顶升横梁踏板,顶升横梁踏板的上方分别安装有位置开关K2和位置开关K3,标节包括标节立柱,标节立柱的侧面安装有标节踏板,套架上固定安装有液压站,液压站上安装有旁路电磁阀,油缸的大腔设置有压力开关K0且沉入油缸的内部。实现利用顶升横梁上的行程开关,自动识别顶升横梁位置是否处于安全位置;当顶升横梁处于安全位置时,液压泵站能驱动液压油缸进行顶升作业;否则中断顶升作业,以此避免顶升危险。
