Description

Measuring instrument for measuring distance

Technical Field

The utility model belongs to the measuring tool field, concretely relates to measuring instrument of measurement interval.

Background

The feeler gauge is a sheet-type measuring tool for measuring the gap size, and at present, China with a publication number of CN205843570U specially facilitates 2016, 12 and 28 discloses an anti-slip single-sheet feeler gauge. The anti-slip clearance gauge can simply and conveniently measure the clearance, and effectively ensures the accuracy of the detection result. In the guide vane structure of the water turbine, a transverse distance exists between two guide vanes of the water turbine, a longitudinal vertical distance exists between one guide vane and the shell, the anti-slip clearance gauge cannot detect the left, the right, the upper and the lower parts of the guide vane simultaneously when detecting regular clearance, and the clearance between the guide vanes of the water turbine needs to be measured one by one, so the measurement efficiency is low.

Disclosure of Invention

An object of the utility model is to provide a can a plurality of intervals of simultaneous measurement's high-efficient measuring instrument.

In order to achieve the above object, the utility model provides a measuring instrument of measurement interval, including clearance gauge shell, fixed column, a plurality of clearance gauges, tooth's socket and elasticity chi, its characterized in that: the shell is provided with a sliding device and a plurality of limiting parts, the sliding device is connected with the limiting parts in a sliding mode, the limiting parts are provided with positioning grooves, and the surface of the shell is provided with scale marks.

In order to limit the guide vane position, be convenient for calculate and read measured data, slider is located the shell upper surface, slider is the recess fretwork form and matches with the shell shape, the constant head tank is located the same one side of each locating part, and the shape indent matches with the guide vane shape.

Because each locating part perfectly agrees with the hydraulic turbine stator appearance, inject each hydraulic turbine stator position, use first locating part as the benchmark, calculate and read the interval between each locating part through the sign on shell surface.

In order to conveniently adjust the corresponding number relationship between the limiting parts and the guide vanes of the water turbine, the limiting parts and the sliding devices are detachably connected.

In order to measure the clearance above or below a plurality of turbine guide vanes, the shell and the feeler are matched with the shape of the turbine.

The utility model has the advantages that: the utility model discloses a constant head tank fixed water turbine stator of locating part, through reading the interval between locating part and the locating part, measure interval about a plurality of hydraulic turbine stator, convex chock block measures a plurality of hydraulic turbine stator below or top interval to also can detect below or top interval when detecting hydraulic turbine stator left and right sides interval, make the arc chock block both detect the measurement of horizontal direction, also can detect the measurement of vertical direction, greatly improved detection efficiency.

Detailed Description

The following is a more detailed description of the present invention by way of specific embodiments.

Example (b): a measuring instrument for measuring distance comprises a shell 1 of a plug piece 6, a fixed column, a plurality of plug pieces, a tooth socket and an elastic ruler, wherein the plug pieces are connected in a plug piece connecting mode disclosed in the Chinese patent with the publication number of CN 205843570U. Be equipped with slider 4 and a plurality of locating part 2 on the shell 1, the technical staff agrees with shell 1 and the outer circumference of hydraulic turbine stator together to use first locating part 2 as the benchmark, adjust slider 4 with bolt on a plurality of locating parts 2 and the elasticity cooperation of nut carry out sliding adjustment, 2 inboard sides of locating part set up constant head tank 5, constant head tank 5 agrees with on the stator, locating part 2 with the scale sign parallel and level that the shell 1 surface set up agrees with every guide vane and constant head tank 5 back of agreeing with together, read 2 position scales of locating part at the back with the scale position of first locating part 2 as zero point.

In order to limit the position of the guide vane and facilitate calculation and reading of measurement data, the sliding device 4 is located on the upper surface of the housing 1, the sliding device 4 is in a hollow groove shape and is matched with the housing 1 in shape, and the positioning groove 5 is located on the same side of each limiting part 2 and is concave in shape.

Because the blades of different water turbines are different, in order to enable the number of the limiting parts 2 to correspond to the number of the guide blades of the water turbine, the limiting parts 2 and the sliding devices 4 are detachably connected.

After position about every stator is injectd to above-mentioned locating part 2, in order to measure the clearance of a plurality of hydraulic turbine guide vane tops or below,

shell

1 and 6 shape of chock pieces match with hydraulic turbine appearance, through locating part 2 to hydraulic turbine guide vane's location, promote a plurality of 6 pieces of chock pieces and fill in the clearance, adjust the upper and lower position of the hydraulic turbine guide vane that is surveyed simultaneously until being had the clearance and can't fill in. The plug 6 can be inserted into a gap above or below the guide vane to perform measurement while measuring the pitch of the guide vanes.
