Problems solved by technology

Due to the obstruction of the ring plate, these ribs usually cannot be installed directly from above using lifting equipment, and instead need to be installed with self-made lever tools or the entire part is turned over before installation. The aforementioned methods are inefficient, poor in safety, and difficult to operate. higher

Embodiment Construction

[0028] The object of the present invention is to provide a method of using a symmetrical lifting device for circumferential assembly, the structure of which is as follows figure 1 , figure 2 As shown, the use radius of the device can be adjusted, and the device can be used to efficiently, safely and easily install the circumferentially evenly distributed ribs that are located below the ring plate and cannot be directly hoisted from above. The technical solution of the present invention is:

[0029] 1) Between the two layers of the same first metal disc 1 with the first circular holes 16 uniformly distributed in arrays in the radius and circumferential direction, eight first metal tubular tubes with a length slightly smaller than the radius of the first metal disc 1 are inserted. Part 2, each first metal tubular part 2 is radially and uniformly distributed with the central axis of the cylindrical surface of the first metal disc 1 as the reference axis, and the contact surface ...

Abstract

The invention aims to provide a using method for a symmetrical lifting device for circumferential assembly. Supporting arms evenly distributed circumferentially are arranged on the device, the using radius of each supporting arm can be adjusted, a rib plate is placed on each supporting arm symmetrically in the circumferential direction, the purpose that each rib plate is used as the balanced counterweight without the need for a separate-arranged counterweight tool can be achieved, the rib plates can be hoisted once, and the rib plates evenly distributed circumferentially and not capable of being directly hoisted above can be efficiently, safely, simply and conveniently mounted below annular plates by using the device.

Description

technical field [0001] The invention relates to a method of using a symmetrical lifting device for circumferential assembly. Background technique [0002] Supporting ribs are often designed under the ring plates of the lower frame and upper frame of the hydro-generator, and the ribs are mostly arranged at circumferentially uniform positions. Due to the obstruction of the ring plate, these ribs usually cannot be installed directly from above using lifting equipment, and instead need to be installed with self-made lever tools or the entire part is turned over before installation. The aforementioned methods are inefficient, poor in safety, and difficult to operate. higher. This requires a tool with high efficiency, high safety and easy operation to install such ribs. Contents of the invention [0003] The object of the present invention is to provide a method for using a symmetrical lifting device for circumferential assembly, the use radius of the device can be adjusted, a...
