Description
Technical field：
The present invention relates to the side in power station in-site installation movable propeller turbine, turned over to rotary wheel of water turbine
Method.
Background technology：
At present, most domestic Kaplan turbine rotary wheel of water turbine is inverted structure, that is, installs and grasped inside web
When making mechanism, runner is inversion state.Runner is carried out after installing integrally to turn over, then the parts such as runner bucket are installed.Turn
It is important step in whole runner installation process that wheel, which turns over, and runner weight is big during due to turning over, and center of gravity is difficult to hold, therefore turns over
Body has higher risk.
Coordinated according to most of each axle stream type power station electromechanics installation situation in the current country, prior art using bridge machine double hook
Air turning mode.Prior art is exactly first to bear weight with a suspension hook, and another suspension hook plays righting runner, when turn
When wheel translates into certain position, the exchange roles of two suspension hooks.Using existing traditional air turning mode, start and tie turning over
Stress point moves at the edge of wheel hub during beam, and force unbalance causes steel wire rope and bridge crane frequently to bear instantaneous impulse,
It is dangerous high, and hub body is easily injured, when turning in the air, due to the transfer of center of gravity, hoist controlling difficulty is big, easily causes
Suspension centre breaks off relations, and occurrence of equipment damage is very risky with personal injury accident.
Due to needing to consider the upstream and downstream lifting limit when power station bridge crane designs, ordinary circumstance is set using double trolley
The crane of meter and car after, it is in larger distance between two main hooks, much larger than turn over when runner on two suspension centre distances, therefore turn over when
Steel wire rope skew is larger, the risk of groove skipping of steel rope while be present, therefore prior art coordinates air turning mode using bridge machine double hook,
It is impossible to meet Hoisting Security requirement.
Existing traditional air turning method is used in addition, is also limited by crane gear, some power station overhead traveling cranes
Machine is the crane gear of single hook, and the method for air turning can not just be completed, therefore higher to the requirements of type selecting of power station bridge machine, power station
Cost of investment increase.
The content of the invention：
It is an object of the invention to provide a kind of simple in construction, cost is low, operation easily, safety, the high axle of operating efficiency
Flow type rotary wheel of water turbine single hook and turn over dress method.
What the present invention was realized in：
Used tool of the present invention includes suspender, first and second support, first, second, third and fourth suspender member, first and second support, institute
State first and second support to be made up of column and base, there is groove column upper end, and there are coaxial aperture, first and second hanging in the two side of groove
Part is symmetrical, has free bearing on its curved plate, has hole on free bearing, if having dry hole and rotary wheel of water turbine on curved plate inner edge circumference
Upper wheel bore coordinates, and the 3rd suspender member is made up of riser with bottom plate, there is first and second hole arranged side by side on riser, and the two of bottom plate are symmetrical
If there is dry hole to coordinate with rotary wheel of water turbine lower whorl hub bore on the circumference of arc side, the 4th suspender member is made up of riser with bottom plate, on riser
There is hole, if there is dry hole to coordinate with wheel bore on rotary wheel of water turbine on the circumference of bottom plate arc side, described first and second supports for supporting water
Turbine Runner.
It is as follows that rotary wheel of water turbine single hook turns over step：
1）If dry hole on the curved plate inner edge circumference of first and second suspender member is connected with wheel bore on runner by bolt
Connect, the steel wire rope of the hole of the free bearing on the curved plate of first and second suspender member two and suspender is connected, by the 3rd suspender member bottom plate
Hole on two symmetrical arc side circumference is bolted with rotary wheel of water turbine lower whorl hub bore；
2）Runner is hung to first support from installation station, the coaxial aperture of the two side of the groove of first support column upper end with
The first hole on the riser of 3rd suspender member is connected with bearing pin；
3）Bridge machine slowly moves, while discharges main hook, completes 90 ° of turns for the first time, runner is positioned in the first support；
4）By first on the riser of the coaxial aperture of the two side of the groove of the column upper end of first support and the 3rd suspender member
Bearing pin in hole takes out, the hole with the 4th suspender member, the 3rd hanging respectively after the taking-up of first and second suspender member by wire rope of sling
The second hole connection of part, rotary wheel of water turbine is sling, first and second support will be supported on by wheel hub thereon, its lower hub is supported on
Second support, the coaxial aperture of the groove of the column upper end of first and second support pass through the hole of axle and the free bearing of first and second suspender member respectively
Connection；
5）By wire rope of sling from the hole of the 4th suspender member, the second hole of the 3rd suspender member take out after by wire rope of sling only
It is connected with the 3rd the first hole of suspender member, suspender lifting, bridge machine slowly moves, while lifts main hook, completes second of 90 ° of runner and turns over
Body.
Used tool of the present invention is simple in construction, and cost is low, and operation is easy, safety, and operating efficiency is high, can make bridge machine single hook
The turn work of axle stream type runner is completed, the security of runner turn greatly improved, avoid because bridge machine steel wire rope is inclined
The excessive lifting risk brought in angle, avoids injury of the steel wire rope to runner, and moment caused by eliminating runner centre-of gravity shift rushes
Risk is measured, makes turn process steady, safe, solves the problem that power station runner turns over, reduce the security risk of runner turn.
The application of the present invention, is turned over using bridge machine list main hook to runner, can be under different occasions, different power stations, different condition
Use, available for institute it is in need carry out runner turn axial-flow rotary propeller type power station, effectively avoid runner turn during, bridge
The potential safety hazards such as machine job-hopping, center of gravity transient deflections, it greatly strengthen security, stability and reliability during turning over.
