Abstract
The technical scheme of the utility model is to provide an anti-loosing structure of a stator supporting rib, which comprises a supporting rib, wherein the supporting rib is provided with a nut outside a partitioning pressure plate; an external tab washer, a washer and an insulating washer are sequentially arranged between the nut and the partitioning pressure plate; the tongue end of the external tab washer is embedded into the washer; and the washer, the insulating washer and the partitioning pressure plate are fixed together through pins. The utility model has the advantages of simple method and convenient inspection after implementation, can not generate careless omission easily, can not damage the thread of the supporting rib and the thread of the nut of the supporting rib, can bring convenience for the retightening of an stator core and the field repair in a power plant, and can realize the purpose of using for many times.
Description
Technical field
The utility model relates to a kind of anti-loose structure of stator support bar, is used to prevent that generator stator core back support bar nut from the project organization of loose or dislocation taking place under permanent ruuning situation, belongs to the stator of steam turbine generator technical field.
Background technology
As shown in Figure 1, be original stator support bar nut anti-looseness structural representation, described stator support bar nut anti-looseness structure comprises support bar 1, support bar 1 is provided with nut 2 in the outside of minute block pressur plate 5, be provided with packing ring 3 and insulating washer 4 successively between nut 2 and the branch block pressur plate 5, original turbine generator stator end support bar nut anti-looseness structure has following two kinds of installation methods:
One, stator end support bar nut adopts the spot welding positioning and fixing structure to vapour end and support bar of encouraging end and nut after closed assembly unshakable in one's determination is finished.This structure is fixed together support bar and nut with Type of Welding, guarantee unshakable in one's determination in long-time running nut do not shaken pine, come off; Though this anti-loose structure can be realized the positioning and fixing means, and easy enforcement simple in structure, this structure has certain damage to support bar screw thread, support bar nut thread, and the tightening up again of stator core, power plant's spot repair are made troubles.
Two, stator end support bar nut adopts ocean hair positioning and fixing structure in a state of excitement to vapour end and support bar of encouraging end and nut after closed assembly unshakable in one's determination is finished.This structure is that hair is fixing in a state of excitement with the ocean with support bar and nut, guarantee in the long-time running unshakable in one's determination nut do not shaken pine, come off; This anti-loose structure realizes that method is simple easily, checks difficulty but implement the back, careless omission easily, support bar screw thread, support bar nut thread are had certain damage, the tightening up again of stator core, power plant's spot repair are made troubles, existing repeatedly accident takes place in concrete the enforcement.
Summary of the invention
The purpose of this utility model provides a kind of generator stator core end support bar nut that can effectively prevent under the long-time running situation, does not become flexible, comes off, and satisfied iron core tightens up the safe and reliable fixing locking project organization of requirement again.
In order to achieve the above object, the technical solution of the utility model provides a kind of anti-loose structure of stator support bar, comprise support bar, support bar is provided with nut in the outside of minute block pressur plate, be provided with lock washer with tongue at outside, packing ring and insulating washer successively between nut and the branch block pressur plate, the tongue end of lock washer with tongue at outside embeds in the packing ring, and packing ring, insulating washer and branch block pressur plate are fixed together by pin.
After screwing in the support bar nut,, can prevent that the support bar nut from rotating, and realizes the nut anti-looseness purpose by the locking of lock washer with tongue at outside flange.This anti-loose structure, method is simple, implements that the back is convenient to be checked, is difficult for careless omission, support bar screw thread, support bar nut thread is not produced damage can offer convenience to the tightening up again of stator core, power plant's spot repair.
The utility model has the advantages that to prevent that effectively generator stator core support bar nut from becoming flexible, coming off, realize unshakable in one's determination tightening up again and do not damage support bar screw thread, support bar nut thread repeat implement structure and can offer convenience the tightening up again of stator core, power plant's spot repair.

Fig. 1 is original stator support bar nut anti-looseness structural representation;
Fig. 2 is the anti-loose structure schematic diagram of stator support bar of the present utility model;
Fig. 3 is that insulating washer is connected end view with pin;
Fig. 4 is that insulating washer is connected vertical view with pin.
Embodiment
Specify the utility model below in conjunction with example.
Embodiment
As shown in Figure 2, be the anti-loose structure schematic diagram of stator support bar of the present utility model.The anti-loose structure of described stator support bar is by support bar 1, nut 2, lock washer with tongue at outside 6, packing ring 7, pin 8, insulating washer 9 and divide block pressur plate 10 to form.Support bar 1 is provided with nut 2 in the outside of minute block pressur plate 10, be provided with lock washer with tongue at outside 6, packing ring 7 and insulating washer 9 successively between nut 2 and the branch block pressur plate 10, the tongue end of lock washer with tongue at outside 6 embeds in the packing ring 7, and packing ring 7, insulating washer 9 and branch block pressur plate 10 are fixed together by pin 8.
Described pin 8 and insulating washer 9 are made up of heatproof insulating material.Pin 8 is combined in the insulating washer 9, one embeds in the branch block pressur plate 10, the other end is embedded in the packing ring 7, lock washer with tongue at outside 6 tongue ends embed in the packing ring 7, so just lock washer with tongue at outside 6, packing ring 7, insulating washer 9 and branch block pressur plate 10 are coupled together, form one, nut 2 prevents that by the locking of lock washer with tongue at outside 6 flange nut from rotating.With the leveling of lock washer with tongue at outside 6 flange, rotatable nut is realized repeatedly application target when tightening up again.
