The invention discloses a double-column type well lid lifting hanger which comprises an upper device body device, a lower device body device and a lifting device, the upper device body device is connected with symmetrically-arranged fixing legs, and the fixing legs are connected with first angle measuring pieces; the upper transformer body device is connected with a lifting device located between the symmetrically-arranged fixing legs, and the lifting device is connected with a laser corresponding to the first angle measuring piece. The cable well lid lifting device can be adaptive to cable well lids of different sizes to generate lifting force of different sizes, and the situation that the lifting force is not enough or too large is avoided, so that dangerous situations such as lifting failure are avoided; the signal size can be changed according to the light irradiation position, the lifting force can be adjusted according to a linear or certain uniform rule, micro-angle monitoring is achieved, and small lifting force adjustment at a micro angle is achieved; elastic operation time can be provided for fixing of the fixed base, it can be ensured that the sliding block is stopped after the fixed base is fixed, elastic operation space is provided through the rotating structure, and the fixing reliability of the whole device is ensured.

    本发明公开了一种双柱式井盖提升挂架,包括:上部器身装置,上部器身装置连接有对称布置的固定腿,固定腿连接有第一测角件;上部器身装置连接有位于对称布置的固定腿之间的起吊装置,起吊装置连接有与第一测角件对应的激光器;能够实现自适应大小电缆井盖产生不同大小的起吊力,避免起吊力不够或过大的情况,从而避免造成起吊失败等危险情况;能够根据光线照射位置来改变信号大小,能够根据线性或一定均匀规律来调节起吊力,实现微小角度的监测,并实现微小角度下的小起吊力调整;能够为固定底座固定提供弹性操作时间,能够确保固定底座固定后停止滑块,并且通过转动结构提供弹性操作空间,确保整个装置固定可靠性。
