Transfer transport table for electrical equipment of transformer substation

Abstract

The invention relates to the technical field of transfer devices, in particular to a transformer substation electrical equipment transfer transport table. The device comprises a movable frame, and the movable frame is of a U-shaped structure in the overlook view angle; a hand-operated movable pulley hoisting assembly is installed on the movable frame, bearing bottom plates are hinged to the inner sides of the two vertical edges of the movable frame, and the hinge axes of the bearing bottom plates are parallel to the vertical edges of the movable frame. The bearing bottom plate has an initial state that the cantilever end is vertically downward and a working state that the cantilever end rotates towards the inner side of the moving frame to be horizontal and bears the electrical equipment, and when the electrical equipment is hoisted to the position above the bearing bottom plate, the bearing bottom is driven by elastic force and switched from the initial state to the working state. A bearing rod which horizontally moves on the movable frame moves to the lower plate surface of the bearing bottom plate so as to lock the bearing bottom plate; and an unlocking trigger piece for driving the bearing rod to unlock the bearing bottom plate is arranged on the moving frame. The lifting device does not need to be driven by electric power, is small in occupied space, and can realize lifting transportation operation executed by a single person.
