The invention discloses a synchronous moving double-counterweight balance tower crane, which relates to the technical field of tower cranes, and comprises a stand column support, a rotating platform is mounted at the upper end of the stand column support, a triangular mounting rack is fixed at the top of the rotating platform, a hoisting support is hinged to one side of the top end of the mounting rack, and a counterweight support is fixed to the other side of the top end of the mounting rack; the lifting support and the counterweight support are supports with the tail ends rising upwards, a lifting crane is installed on a bottom rod of the lifting support in a sliding mode, a double-counterweight device is installed on a bottom rod of the counterweight support, and a linkage device is arranged between the double-counterweight device and the lifting crane. When the hoisting crane moves towards the tail end of the hoisting support, the hoisting support rotates downwards to extrude the piston rod of the oil cylinder I, oil is fed into the oil cylinder II, the piston rod in the oil cylinder II is pushed to move, then the load balance weight is pushed to move towards the tail end of the balance weight support, and according to the lever principle, it is guaranteed that the weight of the two sides of the stand column support is kept stable all the time, and deflection is avoided.
本发明公开了一种同步移动双配重平衡塔吊,涉及塔吊技术领域,包括立柱支架,立柱支架上端安装有一个旋转平台,旋转平台顶部固定有一个三角形的安装架,安装架顶端一侧铰接有起重支架、另一侧固定有配重支架,起重支架与配重支架均为末端上扬的支架,起重支架的底杆上滑动安装有一个起吊车,配重支架的底杆上安装有一个双配重器,双配重器与起吊车之间设置有联动装置。本发明起吊车向起重支架末端移动时,起重支架向下转动挤压油缸一的活塞杆,将油送入油缸二中,推动油缸二中的活塞杆移动,进而推动负荷配重向配重支架末端移动,根据杠杆原理,保证立柱支架两侧始终保持重量稳定,不会发生歪斜。
