Abstract
The utility model discloses the two trans damping vibration-proof structure of a kind of high rotating speed suspended hydrogenerator group, main employing is in the top of high rotating speed suspended hydrogenerator group, the i.e. position that contacts with concrete pedestal, the generator upper cover plate outer ring of generator dcm layer, be evenly arranged this kind of two trans damping vibration-proof structure, this kind of structure is by cover board body, contact bolt, locking nut, the assembly compositions such as ring are imbedded on basis can adjust arbitrarily axis, the self-locking structure of radial force, generator upper strata upper cover plate and peripheral concrete pedestal are combined into entirety to greatest extent, thus make concrete pedestal share Generator Vibration effect, reduce Generator Vibration and vibration sense, ensure that generator set safely and steadily runs.
Description
Technical field:
The utility model relates to the two trans damping vibration-proof structure of high rotating speed suspended hydrogenerator group.
Background technique:
High rotating speed suspended hydrogenerator group causes the radial throw of generator shaft large because the rotating speed of unit own is high; And on whole unit, lead position due to thrust-bearing, be not easy to use conventional vibration protection, cause the type unit usually to vibrate comparatively large, in factory building, generator upper cover plate place can obviously feel that vibration sense is strong.
Summary of the invention:
The object of the utility model patent openly a kind ofly effectively can solve the large two trans damping vibration-proof structure of high rotating speed suspended hydrogenerator group vibration, and the technical solution of the utility model is: by upper cover plate body (1), adjustment bolt (2), locking nut (3), contact bolt (4), ring (5) is imbedded on basis, Y type support (6) forms.
Basis imbed ring (5) and Y type supports (6) be welded into overall after buried foundation, upper cover plate body (1) and basis are imbedded ring (5) and are fixed closing by Use Adjustment bolt (2); After locking nut (3), contact bolt (4) fix conjunction, to contact bolt (4) is screwed in the screw of upper cover plate body (1), make contact bolt (4) all imbed ring (5) with basis to contact completely, then use locking nut (3) to lock and contact bolt (4), reach complete lock state.
Technique effect:
1) in the process of unit operation and vibration passing, locking nut (3) will contact bolt (4) and tightly lock, ensure upper cover plate body (1) and basis imbed ring (5) evenly, close contact, transfer vibrations to efficiently, uniformly in basis.
2) Y type support (6) and basis are imbedded ring (5) and are welded into entirety, add basis imbed ring (5) with basis area of contact with contact the degree of depth, the stability that ring (5) are imbedded on basis can be increased on the one hand, also can increase the transmission efficiency of vibration.
3) when high rotating speed suspended hydrogenerator group is run, unit vibration can be delivered to upper cover plate body (1), now, imbed with basis adjustment bolt (2) that ring (5) tightly contacts, contact bolt (4) and the basis be embedded in basis can be delivered to uniformly imbed vibrating on ring (5), thus vibration is delivered in basis uniformly, base absorption is vibrated, reaches unit vibration damping object.
Accompanying drawing illustrates:
Fig. 1 is the two trans damping vibration-proof structure of high rotating speed suspended hydrogenerator group
Embodiment:
As shown in Figure 1, the two trans damping vibration-proof structure of a kind of high rotating speed suspended hydrogenerator group.
First basis is imbedded ring 5, Y type support 6 be welded into overall after in buried foundation, when installing cover board body 1, ring 5 phase is imbedded closing in Use Adjustment bolt 2 and basis, the height locking of upper cover plate can be realized herein, making upper cover plate body 1 be axially fixed in basis imbeds above ring 5, improves global stability, by locking nut 3, contact bolt 4 is after conjunction, contact bolt 4 is screwed in the screw of upper cover plate body 1, by adjustment with basis imbed ring 5 contact distance and stressed, make the contact bolt 4 on each aspect of circumference uniform distribution all imbed ring 5 with basis to contact completely, adjust rear use locking nut 3 and lock contact bolt 4, reach complete lock state, now because the overall 1 radial even support of upper cover plate is imbedded on ring 5 on basis, make upper cover plate and basic uniform stressed and form stressed entirety, when unit operation vibrates, after vibration passing to upper cover plate, can be delivered in basis uniformly, basis is made to share greatly and to absorb unit vibration, reach damping effect.
Claims (1)
1. the one kind high two trans damping vibration-proof structure of rotating speed suspended hydrogenerator group: it is characterized in that: by upper cover plate body (1), adjustment bolt (2), locking nut (3), contact bolt (4), ring (5) is imbedded on basis, Y type support (6) forms, basis imbed ring (5) and Y type supports (6) be welded into overall after buried foundation, upper cover plate body (1) and basis are imbedded ring (5) and are fixed closing by Use Adjustment bolt (2); After locking nut (3), contact bolt (4) fix conjunction, to contact bolt (4) is screwed in the screw of upper cover plate body (1), make contact bolt (4) all imbed ring (5) with basis to contact completely, then use locking nut (3) to lock and contact bolt (4), reach complete lock state.
