Abstract
The utility model provides a quick installation frock of hydroelectric set runner shaft coupling bolt, includes rigid support, and the rigid support both sides all are equipped with the layer board, are equipped with on the rigid support and rotate the base, rotate base and stopper normal running fit, and the stopper is located between two layer boards, is used for placing the shaft coupling bolt on the stopper, and the hexagonal head of shaft coupling bolt and the spacing groove looks adaptation of stopper. The utility model can realize quick and stable installation, avoid the problem of collision damage of screw holes and initial screw teeth of the stud, and avoid the problems of time and labor waste and easy damage of installation components.
Description
Technical Field
The utility model belongs to the field of mounting tools for coupling bolts of water turbine generator sets, and particularly relates to a quick mounting tool for a coupling bolt of a runner of a water turbine generator set.
Background
The lower coupling bolt single piece of the rotating wheel coupling is heavy, the bolts are simply flipped by manpower (the bolts are positioned below the threaded holes, the screwing mode of the bolts is from down to up) to the screw holes of the lower flange of the main shaft in the actual installation process, the screw holes and the initial screw teeth of the studs are damaged in a collision manner in the multiple installation process, and the method is time-consuming, labor-consuming and easy to damage installation components. Therefore, the technical scheme solves the problems that: how to adopt the instrument to prop the shaft coupling bolt, guarantee simultaneously that the shaft coupling bolt is installed steadily, avoid utilizing the manual work to go direct flip-chip.
Disclosure of Invention
In view of the technical problems existing in the background art, the quick installation tool for the runner coupling bolt of the hydroelectric generating set can realize quick and stable installation, avoid the problem that screw holes and studs start screw collision damage, and avoid the problems that time and labor are wasted and damage to installation components is easy to cause.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a quick installation frock of hydroelectric set runner shaft coupling bolt, includes rigid support, and the rigid support both sides all are equipped with the layer board, are equipped with on the rigid support and rotate the base, rotate base and stopper normal running fit, and the stopper is located between two layer boards, is used for placing the shaft coupling bolt on the stopper, and the hexagonal head of shaft coupling bolt and the spacing groove looks adaptation of stopper.
In the preferred scheme, the supporting plate is matched with a jack, and the jack is used for driving the supporting plate and the rigid support to move up and down.
In a preferred scheme, the upper surface of the supporting plate is provided with a level meter.
The following beneficial effects can be achieved in this patent:
because the weight of the lower coupling bolt single piece of the rotating wheel coupling is large, manual installation is adopted in actual work, which is time-consuming and labor-consuming and is easy to cause damage of installation components. Quick and steady installation can be realized through adopting runner shaft coupling bolt quick installation frock. The problem of screw hole and the initial screw tooth of double-screw bolt collide with the damage appears to avoid wasting time and energy and easily cause the damage of installing component is avoided.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a three-dimensional block diagram of the present utility model;
FIG. 2 is a diagram showing the effect of the present utility model.
In the figure: the device comprises a rigid support 1, a supporting plate 2, a level meter 3, a rotating base 4, a limiting block 5, a limiting groove 501, a coupling bolt 6 and a jack 7.
Detailed Description
Example 1:
the preferable scheme is as shown in fig. 1-2, a quick installation tool for a runner coupling bolt of a hydroelectric generating set, wherein the rigid support 1 is provided with supporting plates 2 on two sides of the rigid support 1, the rigid support 1 is provided with a rotating base 4, the rotating base 4 is in rotating fit with a limiting block 5, the limiting block 5 is positioned between the two supporting plates 2, the limiting block 5 is used for placing a coupling bolt 6, and the hexagonal head of the coupling bolt 6 is matched with a limiting groove 501 of the limiting block 5. The rigid support 1 is a U-shaped frame supported by steel plates, the supporting plates 2 are welded on two sides of the rigid support 1, the supporting plates 2 are matched with the jacks 7, and the jacks 7 are used for driving the supporting plates 2 and the rigid support 1 to move up and down. The lower surface of the pallet 2 may be provided with grooves for cooperation with telescopic rods of the jacks 7. The two jacks 7 are used for synchronously jacking the rigid support 1, the limit block 5 is rotatably arranged in the middle of the rigid support 1, the limit block 5 is used for supporting the coupling bolt 6, the coupling bolt 6 can be rotated by using external force, the jacks 7 are used for jacking while the coupling bolt 6 is rotated, manual supporting of the coupling bolt 6 can be avoided to rotate, so that the labor-saving effect is achieved, and in addition, the rotation process of the coupling bolt 6 is stable due to synchronous lifting of the two jacks 7, and collision damage of screw teeth is avoided. After the coupling bolts 6 are screwed into a plurality of circles, the tool is removed, and the wrench is used for installation continuously.
Further, the upper surface of the supporting plate 2 is provided with a level meter 3. The stability of the two supporting plates 2 is monitored, and the stability of the installation process of the coupling bolts 6 is further improved. The level 3 is a bubble level.
The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
