When the cable well lid lifting device works, firstly, an electromagnet is started to tightly attract a well lid, a base frame is moved to drive a supporting rod to move into a supporting groove of a supporting frame, a worker applies force to press downwards through a handle, and a lever structure with a roller as a fulcrum is formed; the control panel adjusts the position of the balance weight assembly on the base frame through the adjusting mechanism according to pressure information detected by the pressure detection device, that is, the balance weight assembly is driven to be close to the handle, a certain auxiliary lifting effect is achieved, manpower loss is reduced, and a worker can easily lift the well lid and push the well lid to the empty ground to be placed; when the well lid is placed, the control panel drives the counterweight assembly to be away from the handle and close to the roller according to pressure information detected by the pressure detection device, the situation that after complete force unloading, the counterweight assembly still drives the handle to be stressed to swing downwards to cause safety accidents is prevented, after the well lid completely falls to the ground, only the electromagnet needs to be closed, and the well lid has the advantages of being easy and convenient to operate, time-saving and labor-saving.
本发明提供了一种线缆井盖提升装置,工作时,首先启动电磁铁将井盖吸紧,通过移动基架驱使支撑杆移入支撑架的支撑槽上,工作人员通过手柄施力下压,形成以滚轮为支点的杠杆结构,控制面板根据压力检测装置检测到的压力信息通过调节机构调节配重组件在基架上的位置,即驱使配重组件向把手靠近,起到一定的辅助提升的作用,减少人力损耗,工作人员能够轻松将井盖抬起,并将井盖推动至空地处放置;放置井盖时,控制面板根据压力检测装置检测到的压力信息驱使配重组件远离把手并向滚轮靠近,防止完全卸力后,配重组件仍驱使把手受力向下摆动造成安全事故,井盖完全落地后,关闭电磁铁即可,具有操作简便,省时省力的优点。
