The invention relates to the technical field of inspection well lids, and discloses an inspection well lid safety lifting device for municipal road construction. The inspection well lid safety liftingdevice comprises a bracket, the upper portion of an inner cavity of the bracket is slidably connected with a connection plate, and the upper wall of the inner cavity of the bracket is provided with atelescopic column extending to the connection plate; a spool pin is fixedly installed at the lower end of the connection plate, and the lower end of the spool pin is provided with a stress slice; thelower portion of the inner cavity of the bracket is slidably connected with a lantern ring; the right side of the bracket is provided with a driving screw extending to the lantern ring, and an innercavity of the lantern ring is rotationally connected with a first movable ring. According to the inspection well lid safety lifting device for municipal road construction, by arranging the stress slice at the lower end of the spool pin and arranging an alarm, during using, the spool pin is driven to descend through the telescopic column, the driving screw drives the lantern ring to descend, then,a clamping jaw part is adjusted, and accordingly, the effects of reminding a user to operate safely and preventing an inspection well lid from falling off in the lifting process are achieved.

    本发明涉及窖井盖技术领域,且公开了一种用于市政道路施工的窖井盖安全提升装置,包括支架,所述支架的内腔上部滑动连接有连接板,所述支架的内腔上壁设置有延伸至连接板上的伸缩柱,所述连接板的下端固定安装有线柱,所述线柱的下端设置有应力片,所述支架的内腔下部滑动连接有套环,所述支架的右侧设置有延伸至套环上的驱动螺杆,所述套环的内腔转动连接有第一活动环。该用于市政道路施工的窖井盖安全提升装置,通过在线柱的下端设置应力片,配合设置警报器,使用时通过伸缩柱带动线柱下降,配合驱动螺杆带动套环下降,再配合调节卡爪部分,从而达到了提醒用户安全操作、防止窖井盖提升途中脱落的效果。
