220 kilovolt (kv) adjustable type triangular derrick

Abstract

The invention discloses a 220 kilovolt (kv) adjustable type triangular derrick and belongs to the field of live working tools. The 220kv adjustable type triangular derrick is a framework formed by no less than three uprights. The upper ends of the uprights are fixedly connected with a connecting plate, the upper end face of the connecting plate is movably connected with the lower end face of a top plate, and a hoisting ring is fixed at the center of the top plate. Flanges are fixed at the lower ends of the uprights, a transition flange is fixed on the lower end face of each flange, and anti-slipping supporting legs are fixed at the lower end faces of the transition flanges. The 220kv adjustable type triangular derrick has the advantages of being fast and convenient to assemble, high in stability, and capable of effectively reducing working intensity and lowering construction safety hazards, facilitating actual operations of working staff, lowering working difficulty, and meeting requirements of hoisting operation of power transformation equipment of 110kv voltage grade and 220kv voltage grade and the like.

Description

technical field [0001] The 220kv adjustable triangular holding pole of the invention belongs to the field of live working tools. Background technique [0002] There is no lifting device required for maintenance work in the substation, and the equipment in the substation is compactly arranged, the space is small, it is difficult to get in and out of the lifting crane, and the crane has a large operating range, it is not easy to maintain a sufficient safe distance from other substation equipment, and the safety risk is high. Large; when the substation equipment is overhauled and replaced, there is no reliable lifting point on the equipment structure for hoisting, and the temporarily selected lifting point is often not the best lifting point for hoisting operations, and is greatly affected by the layout of the equipment. The implementation of security measures has brought certain difficulties, which has virtually increased the difficulty of the operation. Contents of the inve...
