The invention belongs to the technical field of hoisting, and particularly relates to a hoisting device for a green building assembly type building assembly wallboard. The device comprises steel wireropes and an installation block. According to the device, in the using process, after one of the two steel wire ropes is broken, two sliding blocks are closed towards the middle through ingenious design, the hanging point of the unbroken steel wire rope and the installation block moves to the middle point of the installation block as much as possible, and the facts that the hoisting device reciprocates to swing under the action of gravity of an assembly wallboard and the device, large dynamic loads are generated on the remaining steel wire ropes, the assembly wallboard falls off, and the lifeand property safety on the ground is endangered are prevented. When one of the two steel wire ropes breaks, an installation sliding block on the side moves downwards relative to the corresponding sliding block, and the installation sliding block moves downwards to trigger a corresponding limiting mechanism, so that the limiting mechanism on the side controls the other limiting mechanism to limit an installation sliding block on the other side through the transmission of a gear and a rack; and the resistance in the sliding block moving process is reduced.
本发明属于起吊技术领域,尤其涉及一种绿色建筑装配式建筑装配墙板用的起吊装置,它包括钢丝绳、安装块,本发明中在使用过程中,当两股钢丝绳中其中一股钢丝绳断裂后,通过巧妙设计使得两个滑块向中间靠拢,未断裂的钢丝绳与安装块的挂点尽可能移动到安装块的中点,防止起吊设备在装配墙板和设备的重力作用下发生往复摆动,对剩余的钢丝绳产生较大的动载荷,引起装配墙板掉落,危及地面上的生命财产安全。当两股钢丝绳中其中一个断裂后,该侧的安装滑块就会相对对应的滑块下移,安装滑块下移触发对应的限位机构,使得该侧的限位机构通过齿轮和齿条的传动控制另一个限位机构对另一侧的安装滑块限位;减少了滑块移动过程中的阻力。
