The installation method of movable propeller turbine runner blade of the present invention, including following operating procedure:
(1) first four hangers are installed on runner blade, are connected by chain block with four hangers of bridge machine suspension hook and runner blade；
(2) adjusting stress by chain block after being connected, adjustment blade spindle nose perpendicularity, gudgeon orifice angle are consistent with pivot pin angle；
(3) by bridge machine, blade is inserted at leisure towards corresponding pivot, after pin-and-hole is inserted in pin, a piece threaded tie-strut is screwed in pivoted arm screw hole by be evenly distributed four orientation of runner blade flange bolt hole respectively, on each threaded tie-strut, it is set with inner washer, hollow hydraulic jack, outer washer more successively, outside outer washer, then screws on nut again and tighten；
(4) aforementioned four hollow hydraulic jack is connected with separator by high-pressure hose respectively, will be connected with electronic pressuring pump by separator again；
(5) starting pressuring pump, pressurize to hollow hydraulic jack, make hollow hydraulic jack stand and drive runner blade to move at leisure, bridge machine is followed the most at leisure and is walked towards runner blade installation direction simultaneously；
(6) adding after runner blade moves into place by press-fit bridge machine by hollow hydraulic jack, lay down erecting device, suspender, screw on bolt by number, nut tightens and puts in place, and taps the urgent blade that can complete with sledgehammer and install operation.
Apparatus of the present invention have the advantage that
1. simple in construction, easy to operate, safe and reliable, laborsaving；
2. utilizing synchronous hydra-ulic jacks to pressurize, uniform force, stable, easy Fast Installation puts in place, improves work efficiency simultaneously；
3. by being applied on pivoted arm by the extending force of hydraulic jack, making blade move into place at leisure, will not produce slash strength phenomenon, the screw thread of screw will not be easily subject to damage, will not damage equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of erecting device of the present invention.
Fig. 2 is the structural representation that hydraulic jack, separator and electronic pressuring pump are connected.
In figure: 1 tie-strut, 2 inner washers, 3 hollow hydraulic jack, 4 outer washers, 5 nuts, 6 blades, 7 pivots, 8 pivoted arms, 9 separators, 10 electronic pressuring pumps.
Detailed description of the invention
As it is shown in figure 1, apparatus of the present invention are made up of four threaded tie-struts, 2, four hollow hydraulic jack 3 of 1, four inner washers, four outer washers 4,5,1 separator 6 of four nuts, an electronic pressuring pump 7 and four high-pressure hoses.Four threaded tie-struts 1 are threadeded with pivoted arm 8 screw hole respectively, and in uniform, symmetrical, an inner washer 2 it is socketed on each tie-strut, it is socketed a hollow hydraulic jack 3 again, is socketed an outer washer 4 the most again, finally nut 5 is screwed in tie-strut 1, screw, making inner washer 2 cling on blade 6 bolt hole flange, hollow hydraulic jack clings on inner washer 2, and outer washer 4 clings on hollow hydraulic jack；Four hollow hydraulic jack 3 are connected with separator 9 by high-pressure hose respectively, and separator 9 is connected with electronic pressuring pump 10.
In use, first by installing four hangers on runner blade, it is connected by chain block with four hangers of bridge machine suspension hook and runner blade.Stress is adjusted by chain block after being connected, adjustment blade spindle nose perpendicularity, gudgeon orifice angle are consistent with pivot pin angle, by bridge machine, blade is inserted at leisure towards corresponding pivot, after pin-and-hole is inserted in pin, a piece tie-strut is screwed in pivoted arm screw hole by be evenly distributed four orientation of runner blade flange bolt hole respectively, on each tie-strut, it is set with inner washer, hollow hydraulic jack, outer washer more successively, outside outer washer, then screws on nut again and tighten；Again aforementioned four hollow hydraulic jack is connected with separator by high-pressure hose respectively, will be connected with electronic pressuring pump by pipeline by separator again；Starting pressuring pump, pressurize to hollow hydraulic jack, make hollow hydraulic jack stand and drive runner blade to move at leisure, bridge machine is followed the most at leisure and is walked towards runner blade installation direction simultaneously；Adding after runner blade moves into place by press-fit bridge machine by hollow hydraulic jack, lay down erecting device, suspender, screw on bolt by number, nut tightens and puts in place, and taps the urgent blade that can complete with sledgehammer and install operation.
