Abstract
The invention discloses a kind of turbine chamber fixing means, include the following steps: 1) the auger shell hole in the positioning of runner envelope and support plate；2) drill-through hole on runner locular wall；3) with round steel that the reinforcement foundation net in base plate and former concrete is integrally welded before being poured concrete；4) feather nail is welded on runner chamber outer wall, and rigid support is set inside runner envelope；5) runner envelope is adjusted in place by chock block, screw rod is passed through into runner locular wall, is screwed into the base plate of embedment；6) nut is brought on inner wall of runner chamber one screw rod；7) it is all brought into nut, nut and inner wall of runner chamber spot welding are secured；8) it links into an integrated entity outside runner envelope with the base plate in Transducers Embedded in Concrete, secures runner envelope.Runner envelope is poured using the present invention is interior in a limited space, guarantees that pressure is influenced when runner envelope is not poured by concrete, it is therefore prevented that the installation center of unit deviates, and ensure that unit operational safety is stablized.
Description
Technical field
The present invention relates to a kind of hydraulic turbine construction method of installation, especially a kind of turbine chamber fixing means.
Background technique
Currently, kaplan turbine runner room is the installation center of the hydrogenerator unit, meanwhile, runner envelope is all
In Transducers Embedded in Concrete, its purpose is to guarantee the stability and safety of unit operation.But runner envelope is also that unit is easy
The position cavitated, once the destruction of runner envelope, will affect the stable operation and efficiency of unit.At this stage the case where
Under, power station runner envelope is destroyed in the case where be all that repair welding and polishing are carried out to local breakdown point, but for the broken of large area
In bad situation, so far still without better solution.
Summary of the invention
It is an object of the invention to provide one kind be poured and not by concrete pressure shadow to runner envelope in the confined space
Loud turbine chamber fixing means.
It is realized the purpose of the present invention is technical solution in this way, a kind of turbine chamber fixing means is special
Sign is that described method includes following steps:
1) a certain number of screw holes are bored in the positioning of runner envelope and support plate；
2) boring on the screwhole position of corresponding base plate on runner locular wall can be by the via hole of screw rod, while crossing hole site
Carry out cushion block thickening；
3) the reinforcement foundation net in base plate and former concrete is welded into before being poured concrete using round steel by base plate
One；
4) feather nail is welded on fresh processed runner chamber outer wall, and rigid support is set inside runner envelope；
5) after being adjusted in place runner envelope by chock block, screw rod is passed through into runner locular wall, is screwed into the base plate of embedment,
Until screw rod is screwed into place；
6) nut is brought on inner wall of runner chamber one screw rod；
7) secured to nut and inner wall of runner chamber spot welding after nut is all brought into, between base plate and runner envelope
Screw rod just plays the role of tensing grasp；
8) base plate in the outside and Transducers Embedded in Concrete of runner envelope links into an integrated entity, inside setting rigid support, Gu
Runner envelope is determined.
Wherein, it in the step 6), need to symmetrically be tensed when nut is installed.
By adopting the above-described technical solution, the present invention has the advantages that easy for construction, low in cost, service-strong, adopt
With it in a limited space in runner envelope is poured, guarantee runner envelope when not being poured by concrete pressure influenced, prevent
The installation center offset of unit, ensure that safely and steadily running for unit.
Detailed description of the invention
Detailed description of the invention of the invention is as follows:
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing, but the present invention does not limit to
In these embodiments, any improvement or substitution on the present embodiment essence spirit still falls within the claims in the present invention and is wanted
Seek the range of protection.
Embodiment 1: as shown in Figure 1, 2, a kind of turbine chamber fixing means, described method includes following steps:
1) a certain number of screw holes are bored in the positioning of runner envelope and support plate 1；
2) being drilled on the screwhole position of corresponding base plate 2 on runner locular wall can be by the via hole of screw rod, while should be in mistake
Hole site carries out cushion block thickening；
3) base plate 2 need to use round steel 3 by the reinforcement foundation net in base plate 2 and former concrete before being poured concrete
It is integrally welded；
4) feather nail is welded on fresh processed runner chamber outer wall, and rigid support 4 is set inside runner envelope；
5) after being adjusted in place runner envelope by chock block 5, screw rod 6 is passed through into runner locular wall, is screwed into the base plate 2 of embedment
It is interior, until screw rod 6 is screwed into place；
6) nut 7 is brought on inner wall of runner chamber one screw rod 6；
7) secured to nut 7 and inner wall of runner chamber spot welding after nut 7 is all brought into, between base plate 2 and runner envelope
Screw rod just play the role of tense grasp；
8) base plate 2 in the outside and Transducers Embedded in Concrete of runner envelope links into an integrated entity, inside setting rigid support, Gu
Runner envelope is determined.
Wherein, it in the step 6), need to symmetrically be tensed when nut 7 is installed.
In the present invention, through the above steps, quickly runner envelope can be fixed, very good solution axial-flow type
Turbine chamber is not influenced in casting Concrete by concrete pressure, and runner envelope can be completely fixed on to installation
On position, it ensure that concrete does not generate irreversible influence to runner envelope in casting process, ensure that unit running process
In safety and stability.
