The invention relates to the technical field of building waste transportation, and discloses a protection device for building waste hoisting and vertical transportation. The device comprises a shell, limiting teeth are arranged on the inner wall of the middle of the shell, a rotating shaft is movably connected to the inner wall of the middle of the shell, an air cavity is formed in the inner wall of the middle of the rotating shaft, and a clamping block is movably connected to the outer side of the rotating shaft; and a reaction cavity is formed in the inner wall of the middle of the rotating shaft, and the inner wall of the middle of the reaction cavity is fixedly connected with an arc trigger column. According to the protection device for building waste hoisting and vertical transportation, the rotating shaft drives a centrifugal block to move, the centrifugal block drives a dielectric plate to move, and then a reset spring and a piezoresistor are used in cooperation, so that the effect of triggering the arc trigger column is achieved; and the rotating shaft rotates rapidly, centrifugal force borne by the centrifugal block is larger than traction force of the reset spring, therefore, the centrifugal block drives the dielectric plate to move towards the outer side, at the moment, the dielectric plate shifts, the working voltage of the piezoresistor is triggered, and the arc trigger column generates high-temperature electric arc.
本发明涉及建筑废料运输技术领域,且公开了一种建筑废料吊装垂直运输用保护装置,包括外壳,所述外壳中部内壁开设有限位齿,外壳中部内壁活动连接有转轴,转轴中部内壁开设与气腔,转轴外侧活动连接有卡块,转轴中部内壁开设有反应腔,反应腔中部内壁固定连接有电弧触发柱。该建筑废料吊装垂直运输用保护装置,通过转轴带动离心块运动,离心块带动电介质板运动,再通过复位弹簧与压敏电阻的配合使用,从而达到触发电弧触发柱的效果,转轴快速转动,离心块受到的离心力大于复位弹簧的牵引力,从而使得离心块向外侧带动电介质板运动,此时电介质板发生偏移,从而触发压敏电阻的工作电压,使得电弧触发柱产生高温电弧。
