Abstract

The invention provides a vertical water turbine upper frame lifting device. The device comprises a base, a frame support column, a coiling mechanism, a transverse bracket, a lifting frame and fixtures; the frame support column is fixedly mounted on one side of the base; the transverse bracket is mounted above the frame support column, and is vertically connected with the frame support column; an electric block is connected under a free end of the transverse bracket; the lifting frame is connected under the electric block; multiple fixtures are uniformly mounted at the bottom of the lifting frame; the transverse bracket is provided with a slide rail in the length direction; an electric slide block is connected above the electric block; the electric slide block is mounted on the slide rail;and a hydraulic lifting rod is arranged between the frame support column and the transverse bracket. The device solves the difficulty of no special lifting tool for upper frames, greatly reduces the lifting difficulty of the upper frames, realizes stable lifting and mounting of the upper frames by using the lifting frame and the fixtures, eliminates potential safety hazards, shortens the maintenance period, and greatly saves the manpower and material resources.

Description

technical field [0001] The invention belongs to the technical field of hoisting and hoisting of hydraulic power plant equipment, and in particular relates to a hoisting device for an upper frame of a vertical water turbine. Background technique [0002] The upper frame of the vertical turbine is a radial frame with 8 arms. During the process of unit expansion or maintenance, the upper frame needs to be hoisted and hoisted. However, during the lifting and hoisting process of the upper frame , since there is no lifting tool used, the steel wire rope is usually used to tie the central axis of the upper frame to hoisting directly on site. It is difficult to adjust the upper frame to the ideal horizontal state for hoisting or hoisting, which makes it difficult to achieve stable lifting and hoisting of the upper frame , which is tantamount to increasing the difficulty of lifting the upper frame, reducing the efficiency of maintenance and construction, and also causing certain safe...
