Double-column well lid lifting hanger

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 li
