The invention discloses an underground coal mine manual anti-power-off protection lifting device in the technical field of lifting devices, which comprises a foundation, a mine is arranged in the foundation, limiting seats are fixed at the top and the bottom of the inner walls of the left side and the right side of the mine, and a lifting mechanism is movably arranged between the limiting seats at the top and the bottom. A lifting mechanism is arranged, when power failure occurs, an electromagnetic block is also powered off, then under the action of an elastic telescopic rod, a driving frame upwards enables a driving device to face upwards, then a driving gear is separated from a driven gear, and meanwhile the driving frame upwards drives a second connecting frame to enable a left connecting sleeve to drive a left movable column to face upwards; and the bearing piece is in a fixed state, so that the guide column body cannot rotate, the supporting rotary column cannot rotate, the situation that the supporting rotary column falls down during power failure is avoided, and the use safety is guaranteed.

    本发明公开了提升装置技术领域的一种煤矿井下人工用防断电保护的提升装置,包括地基,所述地基内开设有矿井,所述矿井左右侧内壁顶部和底部均固定有限位座,顶部和底部所述限位座之间活动设置有提升机构。本发明设置有提升机构,当出现断电时,电磁块也断电,随即在弹性伸缩杆的作用下,带动架向上使驱动装置向上,进而主动齿轮与从动齿轮分离,同时带动架向上带动连接架二进而使左侧连接套带动左侧活动柱向上,从而使左右侧的从动锥齿轮分别与左右侧主动锥齿轮相啮合,由于承载件为固定状态,进而导柱体无法转动,所以支撑转柱不会发生转动,进而不会出现在断电时发生下坠的情况,保证使用安全性。
