The invention discloses an automatic lifting and placing control system for a derrick base of a petroleum drilling machine, which comprises the automatic lifting and placing control system for the derrick base of the petroleum drilling machine. Comprising a control operation box, a first hydraulic winch, a second hydraulic winch, a first safety gear, a second safety gear, a first displacement sensor, a second displacement sensor, a first buffer hydraulic cylinder, a second buffer hydraulic cylinder and a control unit. An oil inlet, an oil return port and an oil drainage port are formed in the control operation box, and the oil inlet is connected with the first throttling valve and an oil inlet of the multi-way valve; the electric proportional multi-way valve is used for controlling the two sets of hydraulic winches to lift and release, the high-precision synchronous motor is used for guaranteeing synchronism in the lifting and releasing process, automatic fine adjustment is conducted through the fine adjustment unit when asynchronization occurs, the automation degree is high, and the synchronization performance is good; the system not only can realize synchronous lifting and placing of the derrick base, but also can realize independent action, the two hydraulic winches do not influence each other during independent action, different lifting and placing working conditions are met, and the application is wide.
本发明公开了一种石油钻机井架底座自动起放控制系统,包括一种石油钻机井架底座自动起放控制系统,包括控制操作箱、第一液压绞车、第二液压绞车、第一安全钳、第二安全钳、第一位移传感器、第二位移传感器、第一缓冲液压缸、第二缓冲液压缸和控制单元;所述控制操作箱上设有进油口、回油口和泄油口,进油口分别连接第一节流阀和多路阀的进油口;本发明采用电比例多路阀控制两组液压绞车进行起放,采用高精度同步马达保证起放过程的同步性,当出现不同步时通过微调联进行自动微调,自动化程度高、同步性能好;该系统不仅可以实现井架底座同步起放,也可以实现单独动作,单独动作时两液压绞车互不影响,满足不同起放工况,应用广泛。
