The invention discloses a hydraulic control device of a hybrid power rotary drilling rig and the rotary drilling rig, and the hydraulic control device of the hybrid power rotary drilling rig comprises an engine, a motor, a first pump group, a second pump group, a first main valve group, a second main valve group, an auxiliary valve group, a first actuating mechanism, a second actuating mechanism and a third actuating mechanism, the first pump set and the second pump set separately drive the first executing mechanism, the second executing mechanism and the third executing mechanism to work through the first main valve set, the second main valve set and the auxiliary valve set. The execution mechanism can be driven to work through the engine or the motor, energy conservation and environmental protection can be achieved, the use cost of a user is greatly reduced, normal work can be achieved under the emergency situation or under site condition limitation, the motor can still be adopted to drive the power head during electric driving, the rotational inertia is small, the soil throwing effect is good, and the construction efficiency is high; and no high-voltage wiring harness exists on the vehicle during electric driving, no electromagnetic interference exists, the stability is good, in addition, no transfer case or other components are needed, and the fault rate is low.

    本申请公开一种混合动力旋挖钻机液压控制装置及旋挖钻机,该混合动力旋挖钻机液压控制装置包括发动机、电机、第一泵组、第二泵组、第一主阀组、第二主阀组、副阀组、第一执行机构、第二执行机构和第三执行机构,第一泵组和第二泵组通过第一主阀组、第二主阀组和副阀组分别单独驱动第一执行机构、第二执行机构和第三执行机构工作。本申请中,可分别通过发动机或电机驱动执行机构工作,既能实现节能环保,使用户使用成本大幅降低,又能在突发情况或场地条件限制时正常工作,且能够在电驱时依然采用马达驱动动力头,转动惯量小,甩土效果好,施工效率高,并且电驱时上车无高压线束,没有电磁干扰,稳定性好,另外无需分动箱等部件,故障率较低。
