Abstract
The utility model discloses a manual turning tool for a small capacity vertical hydrogenerator. The manual turning tool comprises an annular supporting plate and a supporting tube. The periphery of the annular supporting plate and the circumference corresponding to a thrust head are uniformly distributed with two or more through holes. The lower end of the supporting tube is fixed on the annular supporting plate. The upper tube wall of the supporting tube is provided with at least one row of holes which comprise at least two round holes. The axes of the two round holes are on the same diameter of the supporting tube. The manual turning tool has the advantages of simple structure, low cost, repeatable use and convenient operation, the manual turning tool is especially suitable for the small capacity vertical hydrogenerator, multiple rows of round holes mean that there are multiple operating heights, and a proper operating height can be selected according to the height of an operator in use. When carrying out turning, the annular supporting plate is fixed on the thrust head by using a bolt, then a push rod is inserted into a round hole with a proper height, and the turning can be carried out.
Description
Technical field
The utility model relates to a kind of artificial hand turning tool for the low capacity vertical hydrogenerator, belongs to vertical machine design, test, Installation and Debugging and maintenance field.
Background technology
The supporting composition generating set of low capacity vertical hydrogenerator and the hydraulic turbine in test, Installation and Debugging and maintenance process, for guaranteeing the generator normal operation, needs unit axis is measured and adjusted, and this is a very important operation.
The axis of so-called unit is exactly the geometric center lines of each link combination of unit rotating shaft, and the space angle relation of this line and runner plate working face and flange faying face formation.During the unit running, if there are the complications of axis, will make each parts produce beat.For example, have larger non-perpendicularity at thrust runner end face or two end face of flange, being reflected in water, to lead the throw at place just very large, more obvious to this phenomenon of suspension type unit.So in the situation that various complications and out of plumb all exist, unit will produce maximum beat.Due to the unit axis out of plumb, on-streamly will produce periodic unequal loading to thrust bearing, throw is excessive simultaneously also has a significant impact water pilot bearing and sealing thereof, causes unit to play pendulum.Therefore after the unit general assembly, for guaranteeing reliable and stable operation, make axis as far as possible near the desired center position, unit axis should be adjusted to the state perpendicular with the runner plate face.
The throw value that unit axis is located by jiggering mode and measurement top guide bearing, lower guide bearing, collector ring, shaft coupling flange and water pilot bearing etc. is determined.Because measurement and the adjustment of unit axis is a loaded down with trivial details job, improves jiggering mode and hand turning tool and also seem particularly important.Restriction due to setting height(from bottom) and the installation dimension of small-capacity generator, the hand turning tool of former disc type uses very inconvenience: generator shaft upper end diameter Φ 110mm, the endoporus that also has Φ 55mm, wall thickness only has 27.5mm, only be drilled with the screw of 6-M12 for mounting or dismounting thrust runner, slip ring instrument are installed, the screw of M12 is less than normal, can't satisfy the size that hand turning tool is installed, and can only get out in the upper surface of thrust runner the screw of 6-M16 in order to hand turning tool to be installed; Only there is 657mm the upper surface of thrust runner apart from ground level, with the artificial jiggering of the hand turning tool operating space insufficient height of disc type; And the weight of former disc type hand turning tool is generally all near 300 kilograms, and volume is larger, and weight is heavier, lifting inconvenience and uneconomical, and this type of hand turning tool often is mounted the workman and abandons, and makes separately easy hand turning tool by oneself as required.This simple and easy hand turning tool is that recruitment some leftover pieces on the ground are welded, disposable often, make coarse and crude, through adjusting, to use dangerously, its surface is without any antirust processing, mostly all can not use when again overhauling to unit, disposable, can only again make when needing jiggering, be also a kind of waste.
The utility model content
The purpose of this utility model is to provide a kind of reusable, and the artificial hand turning tool that is used for the low capacity vertical hydrogenerator easy and simple to handle.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of artificial hand turning tool for the low capacity vertical hydrogenerator, comprise annular support plate and stay pipe, annular support plate is used for being fixed on thrust runner, be evenly distributed with plural through hole on its peripheral circumference corresponding with thrust runner, the stay pipe lower end is fixed on annular support plate, have at least one round on the tube wall of stay pipe top, at least comprise two circular holes in every round, the axis of described two circular holes is positioned on the same diameter of stay pipe.
Preferably, have the hole more than two rows on the stay pipe tube wall, every round is positioned on the different cross section of stay pipe.
Preferably, every round comprises four circular holes that are positioned on the same cross section of stay pipe, and the axis of two relative circular holes is positioned on the same diameter of stay pipe.Best described circular hole has totally 16 of 4 rows.
Preferably, also comprise push rod, the external diameter of described push rod is less than Circularhole diameter.
Preferably, described stay pipe lower end is welded on described annular support plate.
Preferably, described stay pipe is the carbon structure hot rolled seamless steel tube of diameter 219mm.
Preferably, described Circularhole diameter is 70mm.
Preferably, described annular support plate is that steel plate is made.
Preferably, the quantity of described through hole is 6, and through-hole diameter is 18mm.
The utility model is simple in structure, cost is low, reusable, easy to operate, be specially adapted to the low capacity vertical hydrogenerator, annular support plate is fixed on thrust runner, and need not to be arranged on the little generator shaft of diameter, arranging of stay pipe highly improves operation, makes the operating space become large, many row's circular holes mean a plurality of operation height, can select suitable operation height according to operating personnel's height during use.During jiggering, annular support plate is fixed in above thrust runner with bolt, then push rod is inserted in suitable circular hole highly can carry out jiggering.

Embodiment
In the present embodiment, comprise annular support plate 1 and stay pipe 2, be evenly distributed with the through hole 3 of 6 on the peripheral circumference corresponding with thrust runner of annular support plate 1, stay pipe 2 lower ends are fixed on annular support plate 1, and top has 4 and arranges the circular hole 4 of totally 16 Φ 70mm.Four circular holes 4 of every row are positioned on the same cross section of stay pipe 2, and wherein the axis of two relative circular holes 4 is positioned on the same diameter of stay pipe 2.This artificial hand turning tool post-weld annealed, Bluing treatment, weight is 70 kilograms of left and right.
As shown in Figure 5, during use, set bolt 5 with 6 M16 is fixed in annular support plate 1 above thrust runner 6 by through hole 3, and wherein L1～L4 is 4 operation height, can select any one height according to site operation personnel's height, push rod 7 is penetrated in the circular hole 4 of stay pipe 2 of suitable height, promote push rod 7 and rotate, stay pipe 2 namely drives annular support plate 1 and rotates, and annular support plate 1 drives thrust runner 6 and rotates, thrust runner 6 drives generator shaft 8 and rotates, and plays the effect of jiggering.The multiplex external diameter of push rod 7 is that the steel pipe cutting of Φ 60 left and right forms, and can be provided for oneself by the user.
