The invention discloses a lifting device for a tunnel side wall construction trolley, and relates to the technical field of trolley lifting devices. Comprising a bottom support, a bottom support, a lifting mechanism, a driving device, a sliding main rod and an anti-falling protection device, and can run under the condition of power failure on a construction site, active triggering is not needed, and the passive safety of the lifting device is improved. The displacement motion of the anti-falling protection device during falling is utilized to drive a rotating gear to rotate, the rotating gear drives a clamping protection device to slide through a transmission gear, so that a clamping spring is lengthened, and when a clamping strip slides to a clamping groove along with a lifting box falling at a reduced speed, the clamping strip automatically stretches out and is embedded into the clamping groove, so that the clamping strip is prevented from falling off. And the anti-falling protection device cannot continue to slide downwards, so that the lifting box body is prevented from falling, and the lifting device is stopped. Friction rotating plates rotate to be close to and attached to the surface of the sliding main rod, friction force generated by the friction rotating plates and the sliding main rod is utilized, the falling speed of the lifting box is reduced, and harm to workers during falling is reduced.
本发明公开了一种隧道边墙施工台车用升降装置,涉及台车升降装置技术领域。包括底支座、底托、升降机构、驱动装置、滑动主杆和防坠保护装置,本发明可在施工现场断电的情况下运行,无需主动触发,提升了升降装置的被动安全性。利用防坠保护装置坠落时自身的位移运动,带动转动齿轮旋转,转动齿轮通过传动齿轮带动卡位保护装置滑动,使卡位弹簧被拉长,当卡接条随着减速下落的升降箱体滑移至卡槽位置处时,卡接条自动伸出并嵌入卡槽内,使防坠保护装置无法继续向下滑移,从而阻止升降箱体下落,实现升降装置的止停。摩擦转板旋转靠拢并贴合在滑动主杆表面,利用两者产生的摩擦力,降低升降箱体的坠落速度,降低坠落时工作人员受到的伤害。
