The invention relates to the technical field of double-rocker-arm electric derricks and discloses a double-rocker-arm electric derrick which comprises a lower base frame, a slewing bearing is arranged at the top of the lower base frame, an upper base frame is arranged on the upper portion of the slewing bearing, a supporting mechanism is arranged outside the upper base frame, and rocker arm frames are arranged at the two ends of the supporting mechanism. One end of each rocker arm frame is provided with a tension cable used for fixing the angle of the rocker arm frame and a traction cable used for providing traction force to lift a heavy object. By means of the fulcrum adjusting mechanism and the supporting mechanism, when the rocker arm frame lifts a heavy object, large lateral bearing force can be generated, lateral force is applied to the lateral force adjusting mechanism through the fulcrum adjusting mechanism, the lateral bearing capacity of the whole derrick can be increased, the lateral bearing capacity of a slewing bearing can be reduced, and the bearing capacity of the derrick can be improved. The supporting mechanism and the fulcrum adjusting mechanism are matched to form a triangular supporting state, so that the lateral bearing force of the slewing bearing can be reduced to the maximum extent.
本发明公开了一种双摇臂电力抱杆，涉及到双摇臂电力抱杆技术领域，包括下基架，下基架的顶部设置有回转支承，回转支承的上部设置有上基架，上基架的外部设置有支撑机构，且支撑机构的两端均设置有摇臂架，两个摇臂架的一端均设置有用于固定摇臂架角度的拉力索和用于提供牵引力提起重物的牵引索。本发明设置的支点调节机构和支撑机构，当摇臂架起吊重物时会产生较大的侧向承重力，通过支点调节机构将侧向力施加在侧力调节机构上，可以增加整个抱杆的侧向承重能力，减轻回转支承的侧向承重力，支撑机构和支点调节机构的配合能够形成一个三角的支撑状态，可以最大限度地减轻回转支承的侧向承重力。
