Description
Technical field
The present invention relates to water guide shoe method for dismounting and the extracting tool of a kind of hydroelectric power plant, particularly one
Plant sectional type water guide shoe method for dismounting and extracting tool.
Background technology
In current hydroelectric power plant, the water pilot bearing of the hydraulic turbine is typically located on rotary wheel of water turbine
Side, is one of critical piece controlling spindle of hydroelectric generator set throw, and its effect is and other
Guide bearing together, makes the main shaft of control turbine-generator units be maintained at certain center and rotates
And bear the radial force that main shaft passes over.Regulation bush gap and installation for convenience, generally
Use piecemeal metal tile water pilot bearing, including water guide shoe frame, water guide shoe seat, water guide shoe,
Chock block, the first regulation bolt and the second regulation bolt etc., fastening the first regulation bolt can make
Chock block moves down, and fastening the second regulation bolt can make chock block move up, thus adjusts
Gap between water saving guide shoe and turbine shaft, completes the regulation of bush gap.
When overhauling water guide shoe, need to dismantle water guide shoe, check after hanging out watt seat, it is ensured that
Water guide shoe surface impulse-free robustness and high point, after maintenance return dress water guide shoe and by first regulation bolt with
Second regulation bolt regulates bush gap, thus prevents from going out when hydraulic turbine large-diameter is to throw
The situation of existing tile kilning, improves the service life of water guide shoe.
The method of existing dismounting water guide shoe is usually first by the second regulation disassembling bolts, then will
Steel wire rope penetrates in the gap between chock block and water guide shoe that (steel wire rope need to regulate spiral shell through first
Bolt, i.e. between the first regulation bolt and chock block), then steel wire rope is hung to boom hoisting
On suspension hook, then chock block, water guide shoe seat are hung out together with water guide shoe, thus complete water and lead
Watt dismounting.But, the gap between chock block and water guide shoe is less, causes can only using relatively
Thin steel wire rope, and the weight of chock block, water guide shoe seat and water guide shoe is relatively big, during dismounting lifting
Safety is undesirable.Additionally, need during dismounting to remove regulation bolt, cause the position of chock block
Variation occurs, and then makes bush gap that variation to occur, need to readjust after returning dress, check man
Phase is longer；And steel wire rope penetrates and also can cause chock block and the damage of water guide shoe, the cost of overhaul is relatively
Greatly.Therefore, existing maintenance time sectional type water guide shoe method for dismounting also exist safety undesirable,
The problem that maintenance duration is longer and the cost of overhaul is bigger.
Summary of the invention
It is an object of the invention to, it is provided that a kind of sectional type water guide shoe method for dismounting and dismounting work
Tool.The present invention can not only improve safety, additionally it is possible to shortens maintenance duration, reduces and overhauls into
This.
Technical scheme: a kind of sectional type water guide shoe method for dismounting, the method is first will
The both sides being connected to chock block that two hoisting boards are symmetrical, make the jaws on two hoisting boards respectively
Clamp the two ends of chock block top bending part；Then screw the trip bolt connected on screw, make
The end face of trip bolt dog wedge sub-block top bending part；Again by two hoisting boards of steel wire penetrating
On lifting eye, and steel wire rope is connected on the suspension hook of boom hoisting；Finally use lifting
Putting slings two hoisting boards carries out the dismounting of water guide shoe；Thus conveniently dismounting, when shortening dismounting
Between, improve safety.
In aforesaid a kind of sectional type water guide shoe method for dismounting, the side of described train wheel bridge and lower folder
The side of plate is all identical with the arc of water guide shoe arcuate flanks.
In aforesaid a kind of sectional type water guide shoe method for dismounting, described lifting eye be positioned at water guide shoe and
Between chock block, and the side of deflection water guide shoe.
According to the extracting tool constructed by aforesaid a kind of sectional type water guide shoe method for dismounting, including
Hoisting board, the top ends of hoisting board is provided with lifting eye；The bottom connection of hoisting board is horizontally disposed with
Lower plate, lower plate be provided above horizontally disposed train wheel bridge；The one end of train wheel bridge
It is provided with that the other end of screw train wheel bridge is fixing with hoisting board to be connected.
In aforesaid extracting tool, described train wheel bridge is connected by screw and has fastening bolt.
In aforesaid extracting tool, between described lower plate and train wheel bridge, it is provided with jaws, jaws
It is highly 18mm～22mm.
In aforesaid extracting tool, described lower plate and train wheel bridge are arc.
In aforesaid extracting tool, the outside of described lifting eye this have rounding.
Compared with prior art, present invention improves over sectional type water guide shoe method for dismounting and devise
A kind of extracting tool, clamps the two of chock block top bending part by the jaws on two hoisting boards
End, the then top of the tightened bolt presses chock block top bending part by connecting on train wheel bridge
Face, then by the lifting eye on two hoisting boards of steel wire penetrating, finally by boom hoisting
Lift by crane after suspension hook connecting steel wire ropes, thus hang chock block and water guide shoe, the not only side of operation
Just, the demounting procedure of the second regulation bolt is also eliminated, it is to avoid variation occurs in bush gap, keeps away
Exempt from time to readjust bush gap during dress, thus shortened maintenance duration, it is possible to one will have been dismantled
The time-consuming of block piecemeal watt foreshortened to 0.25 hour from original 2 hours；Connected by lifting eye
Connect steel wire rope, thicker steel wire rope can not only be used, improve safety during dismounting lifting,
Damage of steel cable chock block and water guide shoe can also be prevented, reduce the cost of overhaul.Additionally, this
Bright train wheel bridge and the side of lower plate are arc, and the arc one of the radian of arc and water guide shoe
Causing, during convenient lifting, train wheel bridge and lower plate go deep into, between chock block and water guide shoe, not only improving
Safety, additionally it is possible to prevent the scratch of water guide shoe or damage, reducing the cost of overhaul；During lifting
Lifting eye (i.e. lifting by crane stress point) is positioned at the position of deflection water guide shoe in the middle of water guide shoe and chock block,
In center of gravity after lifting force can be made to act on chock block and the combination of water guide shoe, make lifting stationarity
Good, further increase safety.And, the service kit simple in construction that the present invention uses,
Easy to use.Therefore, the present invention can not only improve safety, additionally it is possible to shortens maintenance duration,
Reduce the cost of overhaul, there is simple in construction, advantage easy to use.
