The invention relates to the technical field of hoisting equipment, and discloses a counterweight device for a crane, which comprises a welding assembly, the welding assembly comprises a welding base, a connecting frame is welded on the inner wall of the welding base, and a welding plate is welded on the outer surface of the connecting frame. The worm is driven by the servo motor to rotate, the worm gear can be driven to rotate in the first mounting rod due to the fact that the worm gear is meshed with the worm gear, the bevel gear is driven to rotate in the second mounting rod due to the fact that the worm gear is meshed with the bevel gear, the driving fluted disc is ensured to rotate, and due to the fact that the driving fluted disc is meshed with the rack, the driving fluted disc is driven to rotate. The auxiliary frame assembly can be driven to ascend and descend under limiting of the pressure-bearing type high-strength bolt, the balancing weight can be conveniently installed in the device, when the balancing weight needs to be added, the adding operation of the balancing weight can be conveniently achieved, and it is ensured that the whole balance weight device can stably and effectively work under different balance weight requirements.
本发明涉及起重设备技术领域,公开了一种起重机用配重装置,包括焊接组件,焊接组件包括焊接底座,所述焊接底座的内壁焊接有连接架,所述连接架的外表面焊接有焊接板。本发明通过伺服电机驱动蜗杆进行转动,由于蜗轮与其相啮合,可以带动蜗轮在第一安装杆内进行转动,再由于蜗轮与斜齿轮是啮合状态,带动斜齿轮在第二安装杆内进行转动,确保驱动齿盘得到转动,而由于驱动齿盘与齿条处于啮合状态,可以带动辅助框架组件在承压型高强度螺栓的限位下进行升降,方便将配重块安装在装置内,而当存在需要增加配重块的情况时,也能够方便实现配重块的增加操作,确保整个配重装置在不同配重需求下都能够稳定有效地工作。
