The invention discloses a high-voltage line lower group tower operation protection device which comprises a screw rod and a stand column, the lower end of the screw rod is in transmission connection with a first brake motor, the upper end of the screw rod is sleeved with a sliding block and an electromagnetic brake, the sliding block is located below the electromagnetic brake, and the sliding block is in threaded connection with the screw rod. The protection device for group tower operation under the high-voltage line has the beneficial effects that the lifting rope of the tower crane can be bent, so that goods hung below the lifting rope are moved to the position below the high-voltage line to complete goods lifting work on the premise that the lifting rope keeps a safe distance from the high-voltage line, and therefore group tower operation can be smoothly carried out under the high-voltage line; and the construction progress and efficiency under the high-voltage line are improved.
本发明公开了一种高压线下群塔作业防护装置,包括螺杆和立柱,所述螺杆的下端传动连接有刹车电机一,所述螺杆的上端套设有滑块和电磁制动器,所述滑块位于电磁制动器下方,所述滑块与螺杆螺纹旋接。有益效果:本申请的高压线下群塔作业防护装置能够折弯塔吊的吊绳,使吊绳在与高压线保持安全距离的前提下将吊绳下方悬挂的货物移动至高压线下完成货物吊运工作,因此能够使群塔作业在高压线下顺利展开,提升了高压线下施工作业进度和效率。
