The compensation device comprises a buffer device and a control system, the buffer device comprises a supporting seat, the bottom of the supporting seat abuts against a crown block platform, a buffer cylinder is fixedly connected to the outer side of the supporting seat and located on the crown block platform, a position sensor is arranged on the crown block platform, an energy accumulator is installed on the crown block platform, and the energy accumulator is connected with the control system. The energy accumulator is communicated with the buffering cylinder through a pipeline, a control valve is arranged on the pipeline, and the position sensor, the control valve and the winch are all connected with a control system. The compensation device is installed on the crown block, when a traveling block impacts upwards after a winch roller brakes emergently, the control system controls the energy accumulator to supply liquid to a piston cavity of the buffering cylinder through the control valve and the pipeline, a piston rod of the buffering cylinder stretches out of a fixed pulley block supporting the crown block and moves upwards at the same time, and therefore the relative distance between the fixed pulley block of the crown block and the traveling block is compensated. The purpose of keeping the tension of the rope system is achieved, so that rope disorder of a winch drum is prevented; the structure is simple and maintenance is easy.
本发明公开的防止石油钻井绞车滚筒乱绳的补偿装置,包括缓冲装置和控制系统,缓冲装置包括支撑座,支撑座底部与天车台抵接,支撑座外侧固接有缓冲缸,缓冲缸位于天车台上,天车台上设置有位置传感器,天车台上安装有蓄能器,蓄能器通过管路与缓冲缸连通,管路上设置有控制阀件,位置传感器、控制阀件、绞车均与控制系统连接。本发明的补偿装置,安装在天车上,当绞车滚筒紧急刹车后游车往上冲击时,控制系统控制蓄能器通过控制阀件和管路向缓冲缸塞腔供液,缓冲缸活塞杆伸出支撑天车的定滑轮组同时往上运动,以补偿天车定滑轮组和游车间的相对距离,达到保持绳系张紧力的目的,从而防止绞车滚筒乱绳;结构简单,易于维护。
