Description
Technical field
This utility model belongs to hydraulic turbine maintenance of equipment field, power station, is specifically related to a kind of water turbine shear pin and extracts specially
Use instrument.
Background technology
When closing turbine gate mechanism, there may be the foreign matters such as wood between two stators so that water distributor
Cannot close.So that other stator in addition to two stators that card has foreign body closes off, it is unlikely to destroy driver
Structure, is provided with the shear pin device of destructible on guide vane lever.When having foreign body to block when between stator, guide vane teunnion and guide vane lever can not
Dynamic, and connecting plate rotates under jaw drives, and break pin is produced shearing, when this shearing is more than 1.5 times of normal operating stress
Time, break pin will be cut off, and this stator can depart from control, but other stator still can normal rotation, it is to avoid fault spread.
Break pin needs repairing after being cut off replacing.At present during dismounting break pin, be to use general tool, by break pin from
Under up tap, and space ratio residing for break pin is narrow, taps highly difficult, can waste the plenty of time, and during tapping
Due to the firmly bad grasp of size, easily cause the deformation of other parts of the hydraulic turbine, result in greater loss.
Utility model content
For solving the problem that above technology exists, this utility model provides a kind of and changes simple and convenient, safe and efficient water
Specific purpose tool extracted by turbine break pin.
Its technical scheme is:
A kind of water turbine shear pin extracts specific purpose tool, including instrument overcoat, jacking block, jacking boss, hydraulic pressure storehouse, goes out liquid
Pipe, feed liquor storehouse, piston, connecting rod, depression bar, feed tube, fluid storage storehouse, liquid back pipe, relief valve and check valve, described instrument overcoat
Inner side is provided with hydraulic pressure storehouse, and jacking block is arranged on instrument jacket internal, and jacking block lower end is provided with draw-in groove, jacking block is provided with
Jacking boss, jacking boss is arranged in hydraulic pressure storehouse, and hydraulic pressure storehouse is connected to drain pipe, and drain pipe is connected to feed liquor storehouse, feed liquor storehouse
Inside being equipped with piston, piston upper end is fixedly connected connecting rod, and connecting rod extends to, outside instrument overcoat, wear through instrument overcoat
The small end crossing instrument overcoat is fixedly installed depression bar, and depression bar one end is hinged with instrument overcoat, and feed liquor storehouse is connected to feed tube,
Feed tube stretches into inside fluid storage storehouse, and drain pipe and feed tube are provided with check valve, and fluid storage storehouse is also connected with
One end of liquid back pipe, the other end of liquid back pipe is connected to hydraulic pressure storehouse, and liquid back pipe is provided with relief valve.
The break pin top that the hydraulic turbine uses is provided with bayonet socket.During this tool work, first by the jacking block lower end of instrument
Draw-in groove level puts clamping in water turbine shear pin bayonet socket under, closes the relief valve on liquid back pipe.Mention depression bar, make connecting rod by piston
Mentioning, now the feed liquor storehouse below piston is in negative pressure state, and the liquid in fluid storage storehouse can be along feed tube by unidirectional
Valve enters in feed liquor storehouse；Pressure depression bar, make connecting rod promote piston move downward, piston just by the liquid in feed liquor storehouse along going out liquid
Pipe is entered in hydraulic pressure storehouse by check valve.Owing to check valve prevents the liquid in hydraulic pressure storehouse to pass back in feed liquor storehouse, so top
Rise block and jacking boss will be lifted up.Repeating to press depression bar, the liquid in hydraulic pressure storehouse can get more and more, jacking block and jacking
Boss is the most just lifted higher and higher, and the break pin in the hydraulic turbine has the most just been pulled out out.After break pin is just pulled out completely, beat
Carrying out relief valve, the liquid in hydraulic pressure storehouse also moves down from liquid back pipe flow back fluid storage warehouse, jacking block, finally takes off jacking block
On break pin, fulfil assignment content.
The beneficial effects of the utility model:
This utility model simple in construction, easy to operate, other parts will not be damaged during replacing, it is little to extract strength used, right
Operator require low, and withdrawal process is safe and efficient, practical.
