Description
Technical field
The utility model relates to a kind of guide vane bottom bracket axles, specifically, it is related to a kind of guide vane bottom bracket axle fast dismounting device,
Belong to field of mechanical technique.
Background technique
The hydroelectric power plant Fan Cuo is equipped with three ZZD673-LH-450 hydraulic turbines, wherein guide vane bottom bracket axle as guide vane and top cover it
Between connection, seal member.During unit maintenance, hung out guide vane bottom bracket axle by overhauling project requirement top cover after overhauling
It extracts and clean processing and replace outer ring packing etc., installed after bottom bracket axle overhaul plan is good.
Currently, the conventional method for removing bottom bracket axle is that bottom bracket axle both ends are provided with symmetrical two M10 top wire holes, by two
People respectively screws in a M10*100 mandril in top wire hole and uniformly screws in jackscrew, and slow with jackscrew is screwed in bottom bracket axle slowly
Bottom bracket axle mounting hole is ejected, realizes the maintenance craft for removing bottom bracket axle.
This kind of maintenance craft there are the problem of: 1. bottom bracket axles remove when bottom bracket axle and top cover level requirement it is relatively high, symmetrically
The screw-in length of two jackscrews screwed in must be consistent, if the length for symmetrically screwing in jackscrew has difference, bottom bracket axle center
Line is glanced off with Fast Installation centerline hole, and bottom bracket axle can be stuck in Fast Installation hole, can not normally be split out；2. using this
Kind maintenance craft removes 24 copper sheathings and needs 4 workaday times of 2 people, and maintenance takes a long time；3. top wire hole is soaked for a long time
Deng the problems such as thread corrosion, dirt collection, incrustation, is more, influences the normal development that bottom bracket axle removes work.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of guide vane bottom bracket axle fast dismounting devices, adopt
After this dismounting device, work efficiency is high, failure rate is low, stability is high.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of guide vane bottom bracket axle fast dismounting device,
It is characterised in that it includes upper support bar and lower support bar, set between upper support bar and lower support bar there are two upright bar, upright bar is distinguished
Equipped with limited block, ladder flange is set in the upright bar between limited block and lower support bar, ladder flange can be in limited block under
It is moved between support rod, down-set pull rod is fixed on lower support bar, tie rod end has screw thread, can use spiral shell on pull rod
Cap mounting flange.
The middle position of a kind of prioritization scheme, upper support bar is equipped with downward upper location hole.
A kind of prioritization scheme has lower Positioning holes on ladder flange.
The utility model uses above-mentioned technical proposal, compared with prior art, as long as having the advantage that 1
People can quickly remove completion on half of working day, greatly improve work efficiency；The center of bottom bracket axle and mounting hole
It is easy to be consistent, thoroughly solves the phenomenon for causing bottom bracket axle demolishing process stuck because of bias, failure rate is low, stability
It is high.
The utility model is described in detail below with reference to embodiment.
Detailed description of the invention

Specific embodiment
Embodiment, as shown in Figure 1, a kind of guide vane bottom bracket axle fast dismounting device, including upper support bar 1 and lower support bar 2,
Upright bar 3, upright bar 4 are equipped between upper support bar 1 and lower support bar 2, upright bar 3 is equipped with limited block 5, upright bar 4 is equipped with limited block
6, ladder flange 7 is set in the upright bar 3, upright bar 4 between limited block 5, limited block 6 and lower support bar 2, and ladder flange 7 is limiting
It is moved between position block 5, limited block 6 and lower support bar 2, the middle position of upper support bar 1 is equipped with downward upper location hole 8, lower branch
Down-set pull rod 9 is fixed on strut 2,9 end of pull rod has screw thread, can use nut mounting flange 10 on pull rod 9.
As shown in Fig. 2, the course of work: whole to be inserted into shaft mounting hole 11 on water-turbine top cover guide vane, in bottom bracket axle 13, flange
It 10 is placed on 13 bottom of bottom bracket axle, connect with nut with pull rod 9 firm, ladder flange 7 is mounted on axis on water-turbine top cover guide vane
Big head support member of the plane as jack 12 on mounting hole 11 is covered, there are lower Positioning holes 15 on ladder flange 7, as jack 12
Major part location hole, flange 10 are mounted on 13 lower plane of guide vane bottom bracket axle (bottom bracket axle microcephaly), pull out support as rising for bottom bracket axle 13
Part；1 centre bit of upper support bar is equipped with location hole 8 and is used as jack microcephaly location hole, moves upwards jack-up by jack 12
Upper support bar 1 moves upwardly together middle pull rod 9, lower flange 10 together with bottom bracket axle 10, realizes the maintenance for quickly extracting bottom bracket axle
Technique.
