Indoor transformer bell cover hoisting device

The invention discloses an indoor transformer bell cover hoisting device. A left base and a right base are equipped with a left double-shear lifting device and a right double-shear lifting device which are driven to go up and down by a left hydraulic cylinder and a right hydraulic cylinder respectively; a cross beam is arranged on the top portions of the left and right double-shear lifting devices; the cross beam is provided with a lifting hook for lifting a transformer hanging bell cover; the cross beam is provided with displacement sensors for detecting whether the lifting height of the left double-shear lifting device and the lifting height of the right double-shear lifting device are consistent; and the displacement sensors are connected with a control system. The cross beam comprises left and right groups of longitudinal rods and front two cross rods and back two cross rods, wherein the left and right groups of longitudinal rods are respectively formed by two longitudinal rods; each longitudinal rod is fixedly connected with the top of a shear lifting member of each double-shear lifting device; and the four mutually-parallel cross rods are fixedly connected with the left and right two groups of longitudinal rods mutually. The transformer bell cover hoisting device adopts a double-shear gantry structure; and the maximum lifting height can reach 8 m, and the maximum weightlifting can reach 10 t.
