The invention relates to the technical field of wind generating set equipment, and particularly discloses a protection device for preventing a crane chain from falling to a tower bottom, which comprises a fixed column body, a fixed mounting piece capable of being fixed on the fixed column body and a fixed connecting piece arranged on the fixed mounting piece, one end of the fixed connecting piece is connected with the fixed mounting piece, one end of the fixed connecting piece penetrates through the side wall of the crane chain box and is connected with a cover plate of the crane chain box, and the fixed column body, the fixed mounting piece and the fixed connecting piece are arranged, so that the cover plate of the crane chain box can be protected through the fixed connecting piece; the cover plate is prevented from falling to the bottom face along with the chain, so that the limiting switch at the tail of the chain can be clamped on the cover plate to limit falling of the chain, then the chain is prevented from falling to the bottom face, the safety performance is improved, the risk that the lifting chain and a lifted object fall to the ground under the emergency situation is prevented, and the safety of personnel and equipment is remarkably guaranteed. And the reliability of the equipment is effectively improved.
本发明涉及风力发电机组设备技术领域,具体公开了一种关于防止吊机链条脱落掉至塔底的保护装置,包括固定柱柱体、可固定在固定柱柱体上的固定安装件和设在固定安装件上的固定连接件,所述固定连接件的一端与固定安装件相互连接,固定连接件的一端穿过吊机链条箱的侧壁并与吊机链条箱的盖板相互连接,通过设置固定柱柱体、固定安装件以及固定连接件,使得可以通过固定连接件对吊机链条箱的盖板进行防护,防止盖板随着链条脱落至底面,从而使得链条尾部的限位开关可以卡在盖板上以限制链条的脱落,进而防止链条脱落至底面,提高安全性能,防止突发状况下起重链条连同吊物掉落至地面的风险,显著保证了人员与设备的安全,有效提高了设备的可靠性。
