Abstract
The utility model provides a power station fluted disc speed measuring probe installation and measuring tool, including hugging closely the dogtooth outside and setting up the thickness reference board, the thickness reference board is unanimous with the outer facade radian of dogtooth, and thickness reference inboard is equipped with at least a set of clamping board, forms the draw-in groove that clamps on the dogtooth between clamping board and the thickness reference board. The tool is convenient for determining the installation distance of the speed measuring probe, is simple to operate and can effectively reduce errors.
Description
Technical Field
The utility model belongs to test the speed probe installation auxiliary assembly, a power station fluted disc test the speed probe installation and measuring tool very much.
Background
The speed measuring probe is important equipment for measuring the rotating speed of the unit, and the installation distance of the speed measuring probe is directly related to the accuracy of the rotating speed measurement. The installation distance of the speed measuring probe refers to the distance between the speed measuring probe and the convex teeth, and is optimal within the range of 3 +/-0.5 mm. When the mounting distance of the probe is measured or the probe is replaced, the optimal mounting distance needs to be adjusted repeatedly for multiple times, and time and labor are consumed. Especially, VGS unit, speed probe and fluted disc are located water and lead the oil groove, and the space is narrow and small, and the operation is inconvenient.
The current measurement of the installation distance of the speed measuring probe mainly adopts the steps of selecting proper feeler gauge thickness to be clamped between the convex teeth and the probe, and then reading the feeler gauge thickness to obtain the installation distance. The VGS unit probe installation is firstly roughly installed, then the installation distance is measured by using a feeler gauge, the position is adjusted according to the measured installation distance, and the steps are repeated to enable the probe to gradually reach the required installation distance. The other type of unit firstly determines the installation distance of the probe, selects the feeler gauge with the determined thickness, tightly attaches the feeler gauge to the surfaces of the two convex teeth, adjusts the probe to enable the probe to be attached to the feeler gauge, and tightens the fastening nut to finish the installation.
The fluted disc probe of VGS unit is installed inside the water guide oil groove, and the operation mouth only can hold down alone and install the operation, and maintainer need lie prone at the access hole and measure repeatedly and adjust, and it is extremely inconvenient to operate, and falls into water guide oil groove with foreign matters such as instrument easily.
The clearance gauge is formed by stacking stainless steel sheets with certain thickness, distance measurement or installation is carried out by selecting sheets with different thicknesses, gaps exist among the sheets, and when the probe is pressed against the sheets, the sheets can deform, so that the measurement result is influenced, and the measurement error is increased.
Disclosure of Invention
The utility model aims to solve the technical problem that a power station fluted disc speed probe installation and measuring tool are provided, make things convenient for the installation distance of speed probe to confirm, easy operation, can effectively reduce the error.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a thickness reference plate is arranged on the outer side of a tooth disc speed measuring probe in a clinging mode, the radian of the thickness reference plate is consistent with that of the outer vertical surface of the tooth disc, at least one group of clamping plates are arranged on the inner side of the thickness reference plate, and a clamping groove clamped on the tooth disc is formed between each clamping plate and the corresponding thickness reference plate.
In a preferable scheme, the lower end of the clamping plate is provided with an inclined surface, and the inclined surface inclines towards one side far away from the thickness reference plate.
In a preferable scheme, the clamping plate comprises a V-shaped plate at the upper end, and a vertical plate is arranged at the lower end of the V-shaped plate.
The utility model provides a pair of power station fluted disc speed probe installation and measuring tool only need select the thickness reference board of suitable thickness, through the card dress board with thickness reference integrated circuit board dress at the dogtooth, the adjustment speed probe nut makes the probe support on the outer facade of thickness reference board, and the mounting nut is taken out measuring tool from the dogtooth upside and can be accomplished the probe installation to last nut. The tool can greatly improve the working efficiency, reduce the working difficulty and the maintenance cost, and has popularization value.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the installation of the present invention;
in the figure: convex tooth 1, thickness reference plate 2, clamping plate 3, clamping groove 4, inclined surface 301, vertical plate 302 and "V" shaped plate 303.
Detailed Description
As shown in fig. 1-2, a tool for installing and measuring a speed measuring probe of a fluted disc of a hydropower station comprises a thickness reference plate 2 tightly attached to the outer side of a convex tooth 1, wherein the thickness reference plate 2 is consistent with the radian of the outer vertical surface of the convex tooth 1, the thickness of the thickness reference plate 2 is set according to the distance between the probe and the convex tooth 1, tools with various specifications and sizes in the thickness range of 2.50 mm-3.50 mm can be manufactured, at least one group of clamping plates 3 are arranged on the inner side of the thickness reference plate 2, in the embodiment, the two groups of clamping plates 3 are respectively clamped on the inner sides of two adjacent convex teeth 1, and a clamping groove 4 clamped on the convex tooth 1 is formed between each clamping plate 3 and the thickness reference plate 2.
Selecting a thickness reference plate 2 with proper thickness, clamping the thickness reference plate 2 on the convex teeth 1 through a clamping plate 3, adjusting a speed measuring probe nut to enable the probe to be abutted against the outer vertical surface of the thickness reference plate 2, tightening the nut, and taking out a measuring tool from the upper side of the convex teeth 1 to finish installation. The tool can greatly improve the working efficiency, reduce the working difficulty and the maintenance cost, and has popularization value.
Preferably, the lower end of the clamping plate 3 is provided with an inclined surface 301, and the inclined surface 301 inclines to a side far away from the thickness reference plate 2.
Through setting up inclined plane 301, be favorable to clamping the board 3 of clamping on dogtooth 1, need not break off with the fingers and thumb the board 3 of clamping and can realize the cartridge of the board 3 of clamping.
Preferably, the clamping plate 3 comprises a V-shaped plate 303 at the upper end, and a vertical plate 302 is arranged at the lower end of the V-shaped plate 303.
