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）It is with round steel that the reinforcement foundation net in base plate and former concrete is integrally welded before concrete is poured into a mould；4）Feather nail is welded on runner chamber outer wall, 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 the screw rod of inner wall of runner chamber one；7）Treat that nut all substitutes into, nut and inner wall of runner chamber spot welding are firm；8）Link into an integrated entity outside runner envelope with the base plate in Transducers Embedded in Concrete, secure runner envelope.Runner envelope is poured into a mould using the present invention is interior in a limited space, ensures the influence of pressure when runner envelope is poured into a mould from concrete, it is therefore prevented that the installation center offset of unit, ensure that unit operation safety and stability.

Description

A kind of turbine chamber fixing means
Technical field
The present invention relates to a kind of hydraulic turbine construction method of installation, particularly a kind of turbine chamber fixing means.
Background technology
At present, 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 ensure the stability and security of unit operation.But runner envelope is also that unit is easy The position cavitated, once the destruction of runner envelope, will influence stable operation and the efficiency of unit.In situation at this stage Under, power station destroyed for runner envelope in the case of be all that repair welding and polishing are carried out to local breakdown point, but for the broken of large area In the case of bad, so far still without more preferable solution.
The content of the invention
Runner envelope is poured into a mould in the confined space it is an object of the invention to provide one kind and from concrete pressure shadow Loud turbine chamber fixing means.
Realized the purpose of the present invention is technical solution in this way, a kind of turbine chamber fixing means, it 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）Being bored on runner locular wall on the screwhole position of corresponding base plate can carry out by the via of screw rod, while crossing hole site Cushion block thickeies；
3）Reinforcement foundation net in base plate and former concrete is welded into one by base plate before concrete is poured into a mould, using round steel Body；
4）Feather nail is welded on fresh processed runner chamber outer wall, rigid support is set inside runner envelope；
5）After 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, until Screw rod is screwed into place；
6）Nut is brought on the screw rod of inner wall of runner chamber one；
7）After nut all substitutes into, screw rod base plate and runner envelope between firm to nut and inner wall of runner chamber spot welding Just play the role of tensing grasp；
8）Base plate in the outside and Transducers Embedded in Concrete of runner envelope links into an integrated entity, and there is rigid support in inside, secures runner Room.
Wherein, in the step 6）In, need to symmetrically it be tensed when nut is installed.
By adopting the above-described technical solution, the present invention has the advantages that easy for construction, of low cost, service-strong, adopt With its influence poured into a mould runner envelope, ensure pressure when runner envelope is poured into a mould from concrete interior in a limited space, prevent The installation center offset of unit, ensure that safely and steadily running for unit.
Brief description of the drawings
The brief description of the drawings of the present invention is as follows：
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the top view of Fig. 1.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings, but the present invention does not limit to In these embodiments, any improvement or replacement on the present embodiment essence spirit, still falls within the claims in the present invention and wants Seek the scope 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 with runner locular wall on the screwhole position of corresponding base plate 2 can be by the via of screw rod, while should be in via position Put and carry out cushion block thickening；
3）Base plate 2 need to use round steel 3 to weld the reinforcement foundation net in base plate 2 and former concrete before concrete is poured into a mould Integrally；
4）Feather nail is welded on fresh processed runner chamber outer wall, rigid support 4 is set inside runner envelope；
5）After runner envelope is adjusted in place by chock block 5, screw rod 6 is passed through into runner locular wall, is screwed into the base plate 2 of embedment, Until screw rod 6 is screwed into place；
6）Nut 7 is brought on the screw rod 6 of inner wall of runner chamber one；
7）After nut 7 all substitutes into, spiral shell base plate 2 and runner envelope between firm to nut 7 and inner wall of runner chamber spot welding Bar just plays the role of tensing grasp；
8）Base plate 2 in the outside and Transducers Embedded in Concrete of runner envelope links into an integrated entity, and there is rigid support in inside, secures runner Room.
Wherein, in the step 6）In, need to symmetrically it be tensed when nut 7 is installed.
In the present invention, by above-mentioned steps, quickly runner envelope can be fixed, solves axial-flow type well Runner envelope, from the influence of concrete pressure, can be completely fixed on installation by turbine chamber in cast Concrete On position, it ensure that concrete does not produce irreversible influence in casting process on runner envelope, ensure that unit running process In safety and stability.
