Description
Technical field:
The present invention relates to a kind of feathering vane runner operating mechanism.
Background technology:
Feathering vane runner operating mechanism is all the change being realized blade working angle by hydraulic oil operation at present, traditional arrangement
Mode is that servomotor cylinder is arranged in web top, and crosshead is arranged in web bottom, owing to web bottom is to sluice
Cone, space is less, transmission operation mechanism especially low oil pressure drive mechanism difficult design, and structure space arranges deficiency, easily sends out
Raw movement interference, is unfavorable for reducing web spherical diameter, reducing draft cone size, raising runner anti-cavitation performance.
Summary of the invention:
It is an object of the invention to provide a kind of layout pattern the compactest, design easily realizes, lower the turning of manufacturing cost
Paddle runner operating mechanism.The technical scheme is that a kind of feathering vane runner operating mechanism, web (1) is in entirety
Empty cast structure, shell middle part is sphere, and lower cavity part is as the cylinder body of runner servomotor；Piston rod (4) is with alive
Plug (5) forms an assembly after being assembled by the first snap ring (6), and piston (5) and piston rod (4) can be at the works of both sides oil pressure
Pump in cylinder body under with；Cylinder cap (2) is fixed on web (1) bottom as servomotor cylinder cap by bolt (3),
Cylinder cap (2) and cylinder body collectively constitute servomotor cylinder, and height of cylinder determines the movement travel of piston (5)；Crosshead (7) is disk
Shape, is fixed on piston rod (4) by the second snap ring (8), pumps with piston rod (4), crosshead (7) circle
All cylindrical bands are fluted, are used for and guide holder (9) matched in clearance；Guide holder (9) be cross section be the slide block of concave shape, guide holder
(9) conjunction being fixed on web (1) by bolt (10) at intermediate recessed portions, guide holder (9) both sides are by being slidably matched
In the groove of embedding operation frame (7)；Web gland (20) is fixed on web (1) top, runner by bolt (21) conjunction
Body gland (20) central aperture, axle bed (19) is mounted within the bore by matched in clearance, piston rod (4) and the endoporus of axle bed (19)
Being slip cooperating relationship, axle bed (19) is support guide when piston rod (4) moves up and down；Connecting rod (13) and link pin (14) group
Becoming a set of linkage, this linkage comprises two pieces connecting rod (13) and two pieces link pin (14), the two of two pieces link pin (14)
End is separately mounted in the bore at connecting rod (13) two ends, and the middle part of two pieces link pin (14) is separately mounted to ear handle (11) and connecting lever
(15) in connecting rod pin-and-hole.
Operation principle:
Piston rod and piston pump under the effect of hydraulic oil, drive the crosshead on piston rod up and down reciprocatingly
Motion, guide holder, for crosshead motion guide, prevents crosshead from rotating, and crosshead is by ear handle and by connecting rod and company
The linkage of lever pin composition drives connecting lever, pivot and blade to rotate, thus realizes the change at blade working angle.
When inner oil tube internal switching pressure oil, pressure oil enters piston underside servomotor cylinder, and piston is at the work of pressure oil
Moving upward under with, piston upwards all followed by piston rod and crosshead, and crosshead drives ear handle and linkage upwards to transport
Dynamic, linkage drives connecting lever, pivot and vane clockwise (looking out inside runner) to rotate, and blade working angle diminishes.
Between inner oil tube and piston rod during cut-in pressure oil, pressure oil enters servomotor cylinder on the upside of piston, and piston is in pressure
Moving downward under the effect of power oil, piston rod and crosshead are all followed piston and are moved downward, and crosshead drives ear handle and connecting rod machine
Structure moves downward, and linkage drives connecting lever, pivot and blade (looking out inside runner) counterclockwise to rotate, blade working angle
Become big.
Technique effect:
The feathering vane runner operating mechanism that the present invention relates to is compared traditional arrangement pattern and is creatively utilized web bottom
Casting cavity is used as runner servomotor cylinder body, and runner servomotor is arranged in runner bottom, has both made full use of web bottom empty
Between save again material；Creatively crosshead is arranged in web top, utilizes guide holder motion guide, be conducive to increasing behaviour
Make frame overall dimensions, increase vane operation moment, reduce servomotor cylinder diameter；Linkage is also predominantly located at web centrage
Above, web top larger space is made full use of, it is not easy to move interference；Crosshead drive ear handle and linkage to
During upper motion, linkage drives connecting lever, pivot and vane clockwise (looking out inside runner) to rotate, and blade working angle becomes
Little, when crosshead drives ear handle and linkage to move downward, linkage drives connecting lever, pivot and blade counterclockwise (from turning
Look out inside wheel) rotate, blade working angle becomes big, thus realizes the change of runner bucket operating angle, improves runner work effect
Rate.
This kind of layout pattern compact conformation, drive mechanism especially low oil pressure drive mechanism or the design of multiple-blade drive mechanism
Easily realize, web spherical diameter can be reduced under the conditions of identical runner diameter, reduce draft cone size, reduce runner weight
Amount, improves the anti-cavitation performance of runner simultaneously.
Accompanying drawing illustrates:
Fig. 1 is feathering vane runner operating mechanism schematic diagram
Fig. 2 is that runner operating mechanism Q is to schematic diagram
Detailed description of the invention: as it is shown in figure 1, web 1 is integral hollow cast structure, shell middle part is sphere,
Lower cavity part is as the cylinder body of runner servomotor；Piston rod 4 forms a group after being assembled by the first snap ring 6 with piston 5
Zoarium, piston 5 and piston rod 4 can pump under the effect of both sides oil pressure in cylinder body；Cylinder cap 2 is by bolt 3
Being fixed on web 1 bottom and collectively constitute servomotor cylinder as servomotor cylinder cap, cylinder cap 2 and cylinder body, height of cylinder determines work
The movement travel of plug 5；Crosshead 7 is disc-shape, is fixed on piston rod 4 by the second snap ring 8, with on piston rod 4
Lower reciprocating motion, crosshead 7 circumference cylindrical band is fluted, for coordinating with guide holder 9 glade plane space；Guide holder 9 is that cross section is
The slide block of concave shape, guide holder 9 is fixed on web 1 by 10 conjunctions of bolt at intermediate recessed portions, and guide holder 9 both sides lead to
Cross and be slidably matched in the groove of embedding operation frame 7；Web gland 20 is fixed on web 1 top by 21 conjunctions of bolt, turns
Wheel body gland 20 central aperture, axle bed 19 is mounted within the bore by matched in clearance, and piston rod 4 is to slide with the endoporus of axle bed 19
Matching relationship, axle bed 19 is support guide when piston rod 4 moves up and down；Connecting rod 13 and link pin 14 form a set of connecting rod machine
Structure, this linkage comprises two pieces connecting rod 13 and two pieces link pin 14, and the two ends of two pieces link pin 14 are separately mounted to connecting rod 13
In the bore at two ends, the middle part of two pieces link pin 14 is separately mounted in the connecting rod pin-and-hole of ear handle 11 and connecting lever 15；Inner oil tube 22
It is arranged on the inside of piston rod 4, the cavity composition two-way pressure between internal cavities and inner oil tube 22 and the piston rod 4 of inner oil tube 22
Power oil circuit, respectively leads to the both sides of piston 5；Ear handle 11 is securely fitted on crosshead 7 by bolt 12, and bottom is with link pin
