The invention relates to the technical field of anti-falling protection devices, and discloses a cage lifting anti-falling protection device for a coal mine, which comprises a hoistway main body, the outer side of the hoistway main body is rotatably connected with a hoistway door through a rotating shaft, and the outer side of the hoistway door is fixedly provided with a connecting handle; the device is provided with the anti-falling protection mechanism, if the situation that the lifting rope body is broken occurs, the situation that the cage body is unbalanced is avoided through limiting of the guide frame in the hoistway body, meanwhile, the anti-falling supporting frame can be clamped into the corresponding anti-falling connecting groove to complete supporting and locking, the cage body is limited to the current position, and therefore the lifting rope body is prevented from being damaged. The anti-falling protection effect is achieved, and timely protection can be achieved; the device is provided with a reinforcing protection mechanism, reinforcing of the connecting portion of the supporting limiting frame and the cage body is conveniently completed, the connecting strength of the connecting portion can be improved after the supporting limiting frame and the cage body are fixed, and the safety performance of the cage body is further improved.
本发明涉及防坠保护装置技术领域,公开了一种用于煤矿的罐笼提升防坠保护装置,包括井道主体,所述井道主体的外侧通过转轴转动连接有井道门,所述井道门的外侧固定有连接把手;本装置设置有防坠保护机构,如果出现提升绳主体断裂的情况,通过导向架在井道主体内限位,避免出现罐笼主体失衡的情况,同时防坠落支撑架可以卡入对应防坠连接槽内完成支撑与锁死,使罐笼主体限位在当前位置,达到了防坠保护的效果,而且能够及时保护;本装置设置有加固保护机构,方便地完成支撑限位架和罐笼主体连接部位的加固,可以在支撑限位架与罐笼主体固定后提升连接部位的连接强度,进一步提升罐笼主体的安全性能。
