The invention discloses a high-stability elevator falling protection structure, and relates to the technical field of elevators, the high-stability elevator falling protection structure comprises a base, a placing frame and a lifting plate, two side baffles are fixedly mounted at the top of the base, a top plate is fixedly mounted at the tops of the two side baffles, and a plurality of sliding rods are fixedly connected between the top plate and the base; the device has the beneficial effects that when a rope is broken, a rolling wheel loses support, and a fourth gear rotates under the elastic force action of a first telescopic spring, so that the rope is broken, the fourth gear is driven to rotate, and the rope is driven to rotate; and an inserting rod on one side of a moving block is clamped into a gap between every two adjacent limiting columns, so that a second rotating shaft is limited, a lifting plate is static, the falling protection effect is achieved, and the problem that in the prior art, a rope is broken, materials rapidly descend, and the life of workers is threatened is solved.
本发明公开了一种稳定性高的提升机坠落防护结构,涉及提升机技术领域,包括底座、放置框、升降板,所述底座的顶部固定安装有两个侧挡板,两个所述侧挡板的顶部固定安装有顶板,所述顶板与底座之间固定连接有多个滑杆,所述升降板与多个所述滑杆滑动连接,所述顶板的顶部固定安装有两个第一支撑板,本发明的有益效果为:当绳索发生断裂时,滚轮失去支撑并在第一伸缩弹簧的弹力作用下,使得第四齿轮进行转动,使得移动块一侧的插杆卡进相邻两个限位柱的间隙中,从而将第二转轴进行限位,使得升降板静止,起到坠落防护的作用,解决了现有技术中绳索发生断裂物料急速下降对工作人员的生命造成威胁的问题。
