The invention discloses a lifting device for a grid supporting piece. The lifting device comprises a lifting frame, a lifting beam, a grid supporting holder, a fixed counterweight, an adjustable counterweight and an adjusting device, wherein the grid supporting holder is connected to the front end of the lifting beam, the fixed counterweight and the adjustable counterweight are connected to the rear end of the lifting beam, and the adjusting device adjusts the adjustable counterweight to move back and forth. According to the lifting device for the grid supporting piece, the grid supporting piece is fixed to the front end of the lifting beam through the grid supporting holder, the fixed counterweight and the adjustable counterweight which are used for balancing the lifting beam are arrangedat the rear end of the lifting beam, and the position of the adjustable counterweight is adjusted through the adjusting device under the load state of the grid supporting piece; after load balance isestablished, the grid supporting piece is slowly pushed to the required position in a barrel, the grid supporting piece is loosened, the adjustable counterweight is adjusted to move forwards to the proper position, the lifting beam can be slowly withdrawn after the no-load balance state is established, instantaneous change of the counterweights can be avoided, and the hoisting safety is improved.The lifting device for the grid supporting piece is applied to technical field of steam generator assembly.

    本发明公开了一种栅格支撑件的吊装装置,包括起吊架、吊梁、栅格支撑夹持器、固定配重、可调配重和调节装置,栅格支撑夹持器连接于吊梁的前端,固定配重和可调配重连接于吊梁的后端,调节装置调节可调配重前后移动。此栅格支撑件的吊装装置,吊梁的前端通过栅格支撑夹持器固定栅格支撑件,吊梁的后端设置用于平衡吊梁的固定配重和可调配重,在栅格支撑件负载状态下,通过调节装置调节可调配重的位置,建立负载平衡后缓慢推进格栅支撑件至筒体内所需位置,待松开栅格支撑件,调节可调配重前移至合适位置,待吊梁建立空载平衡状态后即可缓慢退出,能够避免配重瞬间变化,提高吊装安全性,此发明用于蒸汽发生器装配技术领域。
