JPS5953054A - Coupling method for retainer for upper plate of upper bracket of vertical shaft rotary electric machine - Google Patents

Abstract

PURPOSE:To facilitate the assembling work for a vertical shaft rotary electric machine by opening threaded holes for a bolt at a wahser plate which is secured to each arm of an upper bracket and at a washer plate which is secured to a retainer, mounting a mounting plate on each washer plate, and securing the retainer onto the mounting plate. CONSTITUTION:Threaded holes for a bolt are opened at a washer plate which is welded to the prescribed position of each arm 9 of an upper brakcet 7 and at a washer plate which is welded to the prescribed position of a retainer 11. A mounting plate is mounted via a bolt on each washer plate, and the ends of retainers 10-13 are respectively placed onto the mounting plates. Then, after the retainers 10-13 are positioned, they are welded fixedly to the mounting plates.

2).

In the above-mentioned conventional joining method, one or more bolt holes had to be drilled in the -C seat plate to match the bolt holes in each mounting plate +27Il, and the production quality was not good. In recent years, the capacity of water turbine generators has increased, and they have become extremely large, and the bridges have many parts, and the number of screws for the bolts, which are made by matching the actual seats of the seat plates, is in many places, which takes a lot of time to process. Ta.

This invention provides for screw holes for bolts to be drilled in the seat plate fixed by welding to a predetermined position of each arm of the upper bracket, and in the seat plate fixed by welding to a predetermined position of a specific support member. Attach the mounting plate to the plate with bolts, place the end of the member on the corresponding receiver on the plate, and after positioning, secure the member to the mounting plate by welding, and insert the screw hole in the seat plate. The purpose of the support for the upper plate of the upper bracket of a vertical shaft rotating electric machine is to provide a method for joining members, which can be easily processed in a machine shop and which greatly reduces assembly time.

Hereinafter, a coupling method according to an embodiment of the present invention will be explained with reference to FIGS. 2 and 14. Each joint part (1, 1) of each arm part (9) of the upper bracket (7), (at the position 1~, a seat plate is attached via a support plate (a) as shown in Figs. 5 to 4). (A) is fixed by welding, and the connecting part (at the position 1G, the seat plate is fixed via the support plate (A) as shown in Figures 6 to 8) by welding.These seat plates are fixed by welding. Drill a screw hole for the bolt in the bolt. This screw hole machining can be done easily in a machine shop. Also, the receiver should be placed at the joint part a of member 01) as shown in Figures 9 to 21. Weld and secure the support plate (to the seat plate via the support plate) as shown in the figure. Drill screw holes for bolts in this seat plate (A). In addition, screw holes for bolts were also drilled in the seat plate welded onto the connecting part (1 frame + support plate OI of O!a), and then transported to the site and installed on the inner wall of the wind fuselage (to). Embed in.

Next, attach the mounting plate (C) to each seat plate (T) via the liner (C) with bolts (E). Continuing,
For each receiver, place each end of the member (Itj ~ θ[present] on each corresponding mounting plate (c), determine (rl t5j), and weld and secure the receiver member to the mounting plate (c). liner) and align each receiver with the upper surface of the arm part (9) of members 00 to 190F.In this way, each upper plate (20a) to (20c
), the arm portion (9) and each receiver are mounted on the member (10 to θ) with mounting screws.

In addition, the receiver is a member (1 side, (13 other end connecting part rlQl
, Q! For the connection of i, during on-site assembly, attach the liner on each seat board (to the liner) to the mounting plate with bolts (c), and each bridge is attached to the other end of member 0'4, ([6]). Place it on the mounting plate ζη, and after positioning, weld and secure both sides.

As described above, according to the present invention, each seat plate fixed by welding to a predetermined location of each arm of the upper bracket and the receiver disposed between the arms are located at the middle part of the outermost part of the member. Prepare screw holes for bolts on the seat plates fixed by welding, attach the mounting plates to each of these seat plates with bolts, place the end of each receiver on the above mounting plate, and fix both by welding. As a result, the screw holes in the seat plate can be easily machined, and the assembly time can be greatly reduced. No need for a special drilling machine to machine the screw holes in the seat plate by matching the actual parts during assembly, which was previously required.
