Abstract

The invention discloses a special lifting appliance for an inner top cover of a power station unit and a lifting method of the special lifting appliance. The special lifting appliance comprises a plurality of lifting lugs fixed on the inner top cover of the power station unit, wherein each lifting lug comprises an outer lifting lug used for being arranged on an outer ring frame of the inner top cover and an inner lifting lug used for being arranged on an inner ring frame of the inner top cover; each outer lifting lug comprises an outer arc-shaped base plate matched with the outer ring frame, an outer lug plate which is longitudinally arranged is fixedly connected to the middle of the outer arc-shaped base plate, each lifting lug comprises an inner arc-shaped base plate and an inner lug plate, lifting holes are formed in the outer lug plate and the inner lug plate, and bolt holes matched with the outer ring frame and the inner ring frame of the inner top cover are formed in the outer arc-shaped base plate and the inner arc-shaped base plate. A structure of the inner top cover at the top of the unit is connected by virtue of a fitted bolt so as to form the special lifting appliance; the special lifting appliance is simple in structure, and flexible and convenient to install on a site; selection and inspection workloads of hoisting and suspending points can be greatly reduced, and the hoisting process is balanced, safe and reliable.

Description

technical field [0001] The invention relates to a special spreader for the inner top cover of a power station unit and a lifting method thereof. Background technique [0002] The inner top cover of the hydropower unit figure 1 As shown, the inner roof 100 includes an inner ring frame 110 and an outer ring frame 120, and a connecting rod 111 is provided between the inner ring frame 110 and the outer ring frame 120. Since there is no hanger on the inner roof, the installation and maintenance process is based on the site Due to the actual situation of the components, the hoisting method is temporarily adopted by winding steel wire ropes, which brings great danger to the lifting work. Contents of the invention [0003] The object of the present invention is to provide a special spreader and its hoisting method for the inner roof of the hydropower unit, so as to solve the current problem of complicated operation and high risk of lifting the inner roof of the hydropower unit. ...
