The invention relates to the technical field of drilling equipment, and discloses a derrick lifting device capable of quickly moving a drilling machine, which comprises a vehicle-mounted body, a front support assembly is arranged above the front end of the vehicle-mounted body, a power hydraulic station is arranged on the vehicle-mounted body, and a power supply assembly is arranged on one side of the power hydraulic station. A front hydraulic supporting leg and a rear hydraulic supporting leg are arranged below the front end and the rear end of the vehicle-mounted body respectively, a cable winding assembly is arranged on the vehicle-mounted body, and a lifting hydraulic assembly is arranged at the rear end of the vehicle-mounted body. The explosion-proof servo motor enables the connecting rod mechanism to control the multi-way reversing valve to work, the displacement precision of the multi-way reversing valve is controlled to be within 0.5 mm, the lifting hydraulic assembly and the telescopic hydraulic cylinder are driven to work, the delay time of lifting operation of the derrick outside 50 m is shorter than 100 ms, the lifting and stretching delay of the derrick is increased to 100 ms from 5 s, and the safety of the derrick is improved. And the hysteresis phenomenon during hydraulic control is eliminated.
本发明涉及钻井设备技术领域,且公开了一种钻机快移的井架起升装置,包括车载本体,车载本体的前端上方设有前支撑组件,车载本体上设有动力液压站,动力液压站一侧设有动力电源组件,车载本体前后两端下方分别设有前液压支腿和后液压支腿,车载本体上设有线缆收卷组件,车载本体后端设有起升液压组件。本发明通过防爆伺服电机使连杆机构控制多路换向阀进行工作将多路换向阀的位移精度控制在0.5mm以内,并驱动起升液压组件和伸缩液压缸进行工作,使井架在50m以外起升操作的延迟时间低于100ms,使井架起升、伸缩的延时由5s提升到100ms,消除液压控制时的滞后现象。
