A kind of working principle of dynamic cylinder movable propeller turbine draft cone provision for disengagement of the utility model:
As shown in figure 4, before installing this dynamic cylinder movable propeller turbine draft cone provision for disengagement, first have to lower cover plate and
Guide holder removes draft cone；Symmetrically disengaging section is mounted in the mounting hole of guiding axis for mutually fixed with piston cylinder again
Fixing bolt is detachably fixed the half of bolt sum, then the upper end of screw rod is screwed into the guiding after having dismantled fixing bolt
In the mounting hole of axis, fix the cylinder cap bottom of screw rod, guiding axis and piston cylinder mutually, it is necessary to assure the guarantee load of all screw rods
Summation is not less than twice of draft cone weight；The first working plate is promoted from below, and screw rod is made to pass through the first tooling from first through hole
Plate, and the first working plate is mounted in the installation site of lower cover plate of draft cone；Screw rod is set to pass through the center of hollow hydraulic top
Hole, then the second working plate is installed in the lower section of hollow hydraulic top, and the second working plate is fixed on screw rod by nut, at this time
Hollow hydraulic top is supported on the top of the second working plate, that is, completes the preparation for separating draft cone with hub body.
Support component is symmetrically divided into two groups, to guarantee draft cone energy stress balance；Rotate first group of support component
Nut will rise up the hollow of first group of support component of state and hydraulic hold out against between the first working plate and the second working plate；It revolves again
Turn second group of support component nut will rise up state second group of support component hollow hydraulic jacking in than first group support
The slightly lower position of the hollow hydraulic top of component, the weight of draft cone is fully fallen in first group of support component at this time；Disassembly sluices
The hollow hydraulic top of first group of support component is slowly unloaded drops by the connection bolt between cone and hub body, and draft cone is in weight
Also and then slowly decline is let out at this time until the first working plate is fallen on the hollow hydraulic top of second group of support component under power effect
The weight of water cone goes to second group of support component by first group of support component and bears；Lower the height of the nut of first group of support component
Degree, the hollow hydraulic jacking that will rise up first group of support component of state are slightly lower in the hollow hydraulic top than second group of support component
Position, so that the hollow hydraulic top of second group of support component is slowly unloaded drops, under draft cone continues slowly under the effect of gravity
Drop, until the first working plate is fallen on the hollow hydraulic top of first group of support component again；Step rotation recycles according to the method described above
Operation, until draft cone is dropped to the suitable position such as Fig. 5, draft cone is mutually separated with hub body at this time, to open chamber
Body, operator can carry out the upkeep operation of blade operating mechanism.
It, will be on draft cone according to the opposite operating method of disassembly draft cone after completing the maintenance of blade operating mechanism
It is moved back to dress, and is connected with hub body, the connection bolt between draft cone and hub body is tightened, that is, completes tearing open for entire draft cone
Work is filled, realizes in the case where dynamic cylinder Kaplan runner not being hung out the disintegration of machine hole, completes blade operating mechanism
Upkeep operation.
It should be pointed out that above-described embodiment is only to illustrate the technical ideas and features of the present invention, its object is to
It enables those skilled in the art to understand the contents of the present invention and implement them accordingly, it is practical new that this can not be limited with this
The protection scope of type.All equivalent change or modifications according to made by the spirit of the present invention essence should all cover practical new at this
Within the protection scope of type.
