Abstract
The utility model discloses a mounting device for a runner blade of an axial-flow Kaplan turbine. The mounting comprises four threaded support pull rods respectively connected with tumbler screw holes in a threaded manner, each support pull rod is sleeved with an inner washer, a hollow hydraulic jack and an outer washer sequentially and is screwed with a screw nut tightly, in this way, the inner washers cling to blade bolt hole flanges, the hollow hydraulic jacks cling to the inner washers, and the outer washers cling to the hollow hydraulic jacks. The hollow hydraulic jacks are respectively connected with an oil distributor through high-pressure hoses, and the oil distributor is connected with an electric pressurizing pump. Stress applied by the hydraulic jacks synchronously is uniform, and extension force of the hydraulic jacks is applied on tumblers and pivots, so that the blade can slowly move in place without force throwing, threads of screw holes are less prone to being damaged, and equipment is protected from damage.

The axial-flow Kaplan unit of hydroelectric power plant is when the overhaul of expansion property, rotary wheel of water turbine paddle is decomposed, the installation big event that is absolutely necessary, conventionally adopt four hangers are installed on runner paddle, then use four hangers of bridge machine (overhead traveling crane) suspension hook and runner paddle to be connected by chain block, and it is stressed by chain block, to adjust paddle, adjust palm axle head perpendicularity, gudgeon orifice angle is consistent with pivot pin angle, by bridge machine, paddle is inserted at leisure towards corresponding pivot, after pin-and-hole is inserted in pin, paddle set bolt is screwed on, in paddle two, lower two, bridge machine is goed ahead at leisure towards pivot direction, with spanner, follow and screw bolt, and urgent with sledgehammer.There is following defect in this mounting means: 1., because the walking of bridge machine is stable not, has certain deviation, also have pivot spindle nose perpendicularity to have certain deviation, cause and skim strength phenomenon, need to constantly adjust paddle orientation; 2. due to sledgehammer urgent bolt, the screw thread that once occurred bolt, the screw phenomenon that sustains damage.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of erecting device and installation method of axial-flow Kaplan rotary wheel of water turbine paddle, utilize this device can complete steadily, rapidly the fitting operation of paddle, and laborsaving, easy to operate, safety coefficient is high, operating efficiency is high, damage equipment not.
The utility model addresses the above problem with following technical scheme:
The erecting device of the utility model axial-flow Kaplan rotary wheel of water turbine paddle, it is by four threaded tie-struts that match with pivoted arm screw hole, four hollow hydraulic jack, four nuts, a separator, an electronic pressuring pump and several high-pressure hoses form, four threaded tie-struts are threaded with pivoted arm screw hole respectively, and be even, symmetrical, on each tie-strut, be socketed an inner washer, be socketed again a hollow hydraulic jack, be socketed again again an outer washer, finally nut is screwed in to tie-strut, screw, inner washer is clung on paddle bolt hole flange, hollow hydraulic jack clings on inner washer, outer washer clings on hollow hydraulic jack, four hollow hydraulic jack are connected with separator by high-pressure hose respectively, and separator is connected with electronic pressuring pump.
The installation method of the utility model axial-flow Kaplan rotary wheel of water turbine paddle, comprises following operating procedure:
(1) first four hangers are installed on runner paddle, with bridge machine suspension hook and four hangers of runner blade, by chain block, are connected;
(2) after being connected, by chain block, adjust stressedly, adjust palm axle head perpendicularity, gudgeon orifice angle is consistent with pivot pin angle;
(3) by bridge machine, paddle is inserted at leisure towards corresponding pivot, after pin-and-hole is inserted in pin, in four orientation that are evenly distributed of runner paddle flange bolt hole, respectively a threaded tie-strut is screwed in to pivoted arm screw hole, on the threaded tie-strut of each root, be set with successively from inside to outside again inner washer, hollow hydraulic jack, outer washer, then in outer washer outside, screw on again nut and tighten;
(4) above-mentioned four hollow hydraulic jack are connected with separator by high-pressure hose respectively, separator is connected with electronic pressuring pump again;
(5) start pressuring pump, give the pressurization of hollow hydraulic jack, make hollow hydraulic jack stand and drive runner paddle to move at leisure, bridge machine is also followed at leisure towards runner paddle installation direction and is walked simultaneously;
(6) after being added interference fit bridge machine runner paddle is moved into place by hollow hydraulic jack, lay down erecting device, suspender, screw on by number bolt, nut tightens and puts in place, and knocks and urgently can complete paddle fitting operation with sledgehammer.
The utility model device tool has the following advantages:
1. simple in structure, easy to operate, safe and reliable, laborsaving;
2. utilize synchronous hydra-ulic jacks to pressurize, stressed even, stable, easily Fast Installation puts in place, increases work efficiency simultaneously;
3. by the extending force of hydraulic jack is applied on pivoted arm, blade is moved into place at leisure, can not produce and skim strength phenomenon, the screw thread of screw can easily not sustain damage, can damage equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model erecting device.
Fig. 2 is the structural representation that hydraulic jack, separator and electronic pressuring pump are connected.
In figure: 1-tie-strut, 2-inner washer, 3-hollow hydraulic jack, 4-outer washer, 5-nut, 6-paddle, 7-pivot, 8-pivoted arm, 9-separator, 10-electronic pressuring pump.
The specific embodiment
As shown in Figure 1, the utility model device consists of four threaded tie-struts 1, four inner washers 2, four 6, one electronic pressuring pumps 7 of 5,1 separators of 4, four nuts of 3, four outer washers of hollow hydraulic jack and four high-pressure hoses.Four threaded tie-struts 1 are threaded with pivoted arm 8 screw holes respectively, and be even, symmetrical, on each tie-strut, be socketed an inner washer 2, be socketed again a hollow hydraulic jack 3, be socketed again again an outer washer 4, finally nut 5 is screwed in to tie-strut 1, screw, inner washer 2 is clung on paddle 6 bolt hole flanges, and 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 will four hangers be installed on runner paddle, with bridge machine suspension hook and four hangers of runner blade, by chain block, be connected.After being connected, by chain block, adjust stressed, adjust palm axle head perpendicularity, gudgeon orifice angle is consistent with pivot pin angle, by bridge machine, paddle is inserted at leisure towards corresponding pivot, after pin-and-hole is inserted in pin, in four orientation that are evenly distributed of runner paddle flange bolt hole, respectively a tie-strut is screwed in to pivoted arm screw hole, on each root tie-strut, be set with successively from inside to outside again inner washer, hollow hydraulic jack, outer washer, then in outer washer outside, screw on again nut and tighten; Above-mentioned four hollow hydraulic jack are connected with separator by high-pressure hose respectively, separator is connected with electronic pressuring pump by pipeline more again; Start pressuring pump, give the pressurization of hollow hydraulic jack, make hollow hydraulic jack stand and drive runner paddle to move at leisure, bridge machine is also followed at leisure towards runner paddle installation direction and is walked simultaneously; After being added interference fit bridge machine runner paddle is moved into place by hollow hydraulic jack, lay down erecting device, suspender, screw on by number bolt, nut tightens and puts in place, and knocks and urgently can complete paddle fitting operation with sledgehammer.
