Abstract
The utility model discloses a special dismounting tool for runner blade copper sleeves, which comprises a main beam, at least four screws (3) and screw caps thereof and a sector steel plate (2), wherein the main beam is mounted on a runner body through the four screws and the screw caps, and the sector steel plate (2) is placed on a copper sleeve to be utilized as a supporting point of a jack. The main beam is a case-shaped beam (1) assembled by two channel steels. The special dismounting tool for runner blade copper sleeves is adaptable for dismounting all bulb tubular turbines, movable propeller turbines and other shaft sleeves of other transitional fit components, and can complete dismounting work under the condition of not breaking the shaft sleeves. The complete shaft sleeves bring convenience for use level survey, and provide data basis for changing spare parts in the future.
Description
Technical field
The utility model relates to a kind of dismounting specific purpose tool, particularly relates to a kind of runner blade copper sheathing dismounting specific purpose tool.
Background technology
The runner of disintegration hydroelectric generator and complete dismounting blade and bindiny mechanism's copper bush difficulty of construction thereof are big, the general at present destructiveness dismounting copper sheathing that adopts, and then the web of local damage repaired, not only destroyed the complete of copper sheathing, and damage is caused to web in the dismounting back.
The utility model content
Technical problem to be solved in the utility model provides a kind of injury-free runner blade copper sheathing dismounting specific purpose tool of complete sum web that can guarantee copper sheathing.
In order to solve the problems of the technologies described above, the runner blade copper sheathing dismounting specific purpose tool that the utility model provides, comprise a girder, comprise at least 4 described girder is installed in screw rod and nut thereof on the web, also comprise a fan-shaped steel plate that is positioned on the copper sheathing as the strong point of jack.
Described girder is by two box-girders that channel-section steel is assembled.
Adopt the runner blade copper sheathing dismounting specific purpose tool of technique scheme, broken traditional method of knocking of conventional dismounting interference fits parts, avoided destructive dismounting copper sheathing that web is caused damage, adopt even stressed method integral body to dismantle, for the dismounting of component of the same type provides a kind of new dismounting technology, has certain generalization.
The making of this runner blade copper sheathing dismounting specific purpose tool is used, and following advantage is arranged:
(1), copper sheathing dismounting specific purpose tool makes simply, draws materials easily, cost of manufacture is low, easy to use and effect is better;
(2), intactly finish the dismounting of copper bush, avoided to the destruction of copper sheathing with to the damage of web;
(3), complete copper sheathing helps the measurement to the copper sheathing physical dimension, draws the use level at each position by the dimensional measurement to copper sheathing and web matching part, the data that draw are changed the data foundation are provided for later major overhaul carries out copper sheathing;
(4), the processing and fabricating of specific purpose tool has alleviated the labour intensity that copper sheathing is dismantled, has accelerated copper sheathing dismounting progress, has shortened the unit maintenance duration.
In sum, the utility model is a kind of injury-free runner blade copper sheathing dismounting specific purpose tool of complete sum web that can guarantee copper sheathing.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, box-girder 1 is by [120 * 800 two channel-section steels are assembled into, box-girder 1 is as the strong point of 32T screw jack 6, box-girder 1 is installed in blade by 4 " D " M20 * 600mm screw rod 3 on the type sealing clamp bolt hole and equipped eight M20 fixed by nut on web 5, be positioned on the copper sheathing 4 another strong point by the fan-shaped steel plate 2 of δ 20 * 530 * 200 as 32T screw jack 6.
Referring to Fig. 5, disassembling section step: at first dismantle the neat seam bolt (20) between φ 500 copper sheathings 4 and runner, box-girder 1 usefulness M20 * 600mm screw rod 3 of making is fixed in the bolt hole of blade " D " type sealing clamp, box-girder 1 must be installed in the center of copper sheathing 4, then with 6 one positive one anti-being placed on the fan-shaped steel plate 2 of 32T screw jack, the two ends of fan-shaped steel plate 2 must not surpass the wall thickness of copper sheathing 4, in order to avoid damage female web 5 in unloading process; After two 32T screw jack 6 are evenly stressed, by two staff's while application of forces copper sheathing is slowly ejected again.
This runner blade copper sheathing dismounting specific purpose tool has been avoided in the φ 500 copper sheathing unloading process former copper sheathing and web being caused damage, has guaranteed that the complete sum of φ 500 copper sheathings does not cause damage to web.
This runner blade copper sheathing dismounting specific purpose tool is applicable to the Φ 500 axle sleeves dismounting of all bulb through-flow turbines, movable propeller turbine and other interference fits parts, under the situation of not destroying axle sleeve, finish dismantlement work, the use level that complete axle sleeve is convenient to overlap with the hole is measured, and changing for later spare unit provides the data foundation.
