Abstract
The utility model relates to a kind of Kaplan turbine crossheads, including crosshead and connected ear handle integrated with crosshead, crosshead offers centre bore, central hole, which is worn, is connected to servomotor bar, servomotor bar is connected with key and transmits torque by key, ear handle is movably connected by connecting plate pin with connecting plate, and connecting plate is then connected with pivoted arm power, drives blade rotation by pivoted arm.Processing technology has effectively been simplified, the production cost of part is reduced；Crosshead and ear handle be it is integrated, be entirely capable of bearing big transverse load, be conducive to the structure design of correlated parts；In the process of running, there is the case where ear handle falls off never again in the hydraulic turbine, so that the economic benefit in power station be avoided therefore to be affected.
Description
Technical field
The utility model belongs to turbine equipment technical field, is related to a kind of Kaplan turbine crosshead.
Background technique
In existing Kaplan turbine blade operating system, crosshead and ear handle are individual parts, in their difference
After processing, then it will be assembled in the hole of ear handle screw rod insertion operation frame by attaching nut.In the feelings that production technology falls behind
Under condition, this structure is conducive to processing and size Control.But after processing technology is mature, this structure seems excessively cumbersome, adds
Work and assembly it is at high cost；If threaded pre-tightening power control or locking measures are done badly when assembly, operational process there is also
The phenomenon that middle ear handle falls off.In addition, due to not being tight fit between ear handle screw rod and operation frame aperture, so unbearable big cross
To load, which limits the structures of correlated parts.
Utility model content
In order to overcome the disadvantages mentioned above of the prior art, the utility model provides a kind of Kaplan turbine crosshead, operation
Frame carries ear handle, simple and compact in structure, has effectively achieved the optimization of structure and performance.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of Kaplan turbine crosshead, packet
It including crosshead and connected ear handle integrated with crosshead, crosshead offers centre bore, central hole, which is worn, is connected to servomotor bar,
Servomotor bar is connected with key and transmits torque by key, and ear handle is movably connected by connecting plate pin with connecting plate, connecting plate then with pivoted arm power
It is connected, blade rotation is driven by pivoted arm.
The ear handle quantity is identical as blade quantity and is evenly arranged on crosshead.
Feather key is provided with for preventing crosshead from rotating in the side of the ear handle.
The servomotor bar is fixedly linked by snap ring and stop collar with crosshead.
The beneficial effects of the utility model are: effectively having simplified processing technology, the production cost of part is reduced；Operation
Frame and ear handle be it is integrated, be entirely capable of bearing big transverse load, be conducive to the structure design of correlated parts；The hydraulic turbine is being run
In the process, occurs the case where ear handle falls off never again, so that the economic benefit in power station be avoided therefore to be affected.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
In figure: 1- crosshead, 2- connecting plate pin, 3- connecting plate, 4- servomotor bar, 5- pivoted arm, 6- feather key, 7- stop collar, 8-
Snap ring, 9- key, 10- ear handle.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to Fig. 1, a kind of Kaplan turbine crosshead, including crosshead 1 and connected ear handle integrated with crosshead 1
10,10 quantity of ear handle is identical as blade quantity and is evenly arranged on crosshead 1；The side of the ear handle 10 is provided with feather key 6
For preventing crosshead 1 from rotating；Crosshead 1 offers centre bore, and central hole, which is worn, is connected to servomotor bar 4, and servomotor bar 4 passes through
Snap ring 8 and stop collar 7 are fixedly linked with crosshead 1, and servomotor bar 4 is connected with key 9 and transmits torque by key 9, and ear handle 10 passes through
Connecting plate pin 2 is movably connected with connecting plate 3, and connecting plate 3 is then connected with 5 power of pivoted arm, drives blade rotation by pivoted arm 5.
The utility model has effectively simplified processing technology, reduces the production cost of part；Crosshead 1 is with ear handle 10
One, it is entirely capable of bearing big transverse load, is conducive to the structure design of correlated parts；The hydraulic turbine in the process of running, then
The case where ear handle 10 falls off will not occur, so that the economic benefit in power station be avoided therefore to be affected.
