The present invention relates to a wheel gauge inspection block gauge for accurately and conveniently inspecting the precision of a wheel gauge.

The wheel wear measurement gauge (hereinafter, referred to as a wheel gauge) is a state of the flange 22 and the tread surface 23, which are each component of the wheel 21 assembled to the axle 25 of the railway vehicle, and the wear and deformation of the rim 24, etc. It is a device for measuring condition accurately and easily.

An example of such a wheel gauge is shown in FIG.

According to Fig. 5, the wheel gauge is a gauge which is vertically in close contact with a vertical direction perpendicular to the left side face 23 portion and the right rim face 24b on the center of the flange 22 of the wheel 21, the measurement object. Adjacent to the horizontal mover 2 inserted into the main body 1, the horizontal groove 1c on the left side of the gauge main body 1, and capable of sliding left and right, and the vertical ruler 1e on the right side of the gauge main body 1. Inserted into the vertical groove (1f) is a vertical mover (3) capable of up and down sliding movement, the assembly of the gauge body (1) and the horizontal mover (2), as well as the guide function to smoothly move left and right Guide nut (4) and bolt (5), and guide nut (6) and bolt (7) having a guide function for assembling, fastening, and moving the gauge body and vertical mover (3) smoothly. It is.

In addition, the main body 1 measures the rim thickness gauge 1d 1 for measuring the flange rim thickness 24a inside the vertical bar 1d of the gauge main body 1 , and measures the flaw surface scratch 23a on the outside. It is possible to measure by measuring the surface scratch gauge (1d 2 ), and convexly processed with semi-circle of a certain dimension to measure the depth of groove (26) remaining on the inner surface of the flange at the center of the lower end of the vertical bar (1d). It has a machined surface with a groove depth measurer (1k) remaining on the inside of the flange.

In addition, the horizontal body (2) is inserted into the left horizontal groove (1c) of the gauge main body (1), and moved horizontally to measure the flange thickness (22a) by the horizontal ruler (1b) to indicate the measured value, and horizontal It consists of a guide nut (4) and a guide bolt (5) having a fastening, tightening, and guiding function for assembling and fastening the mover (2) and the main body (1) to smoothly move the left and right, and the right vertical groove of the main body (1) (1f) is inserted and mounted and slid up and down to measure the height of the flange 22b by the vertical ruler (1e) and the vertical mover (3) pointing to the measured value, and assembled between the vertical mover and the main body (1) to move up and down It consists of a guide nut (6) and a guide bolt (7) having a fastening, tightening, and guiding function.

However, the conventional wheel gauge has the following problems.

Since there is no dedicated tool and gauge for inspecting the wheel gauge at present, there is a problem in that the measurement value is different for each wheel gauge for inspecting the wheel and the measurement error cannot be determined.

In addition, when the wheel gauge for inspecting the wheel is defective, accurate wheel measurement is impossible, and even if the wheel gauge is repaired through the wheel correction, an error may occur as much as an error of the wheel gauge for measuring the repair result.

This causes not only a problem in the reliability of measurement data between the worker inspecting the wheel and the worker repairing the wheel, but also a large safety accident such as a railway vehicle derailment when the wheel shape exceeds the prescribed range.

Hereinafter, the inspection state of the wheel gauge inspection block gauge of the present invention configured as described above is as follows.

Slightly loosen the fastening means 210 of the fixing plate 200, slightly loosen the fastening means 310 of the fixing washer 300, and as shown in FIG. 2, the vertical bar in the slide groove 101. Slide (1d) to seat.

Then, after confirming that the lower end support point 1a of the wheel gauge 1 abuts the lower end of the extension part 123, the fastening means 210 is completely tightened to fix the fixing plate 200 to one side of the upper surface of the vertical bar 1d. Cover, and tighten the fastening means 310 so that the fixing washer 300 is in close contact with the upper surface of the vertical bar (1d).

Thus, the vertical bar (1d) is completely fixed to the slide groove 101, the following inspection can be made.

First, as shown in Figure 2, using the reference scale formed in the first measuring unit 110, the scale of the rim thickness measurer (1d 1 ) for measuring the height of the height of the step formed on the vertical bar (1d) is Can be checked for accuracy

Next, as illustrated in FIG. 3, the fastener 6 of the wheel gauge 1 is released to move the longitudinal mover 3 upward so that the longitudinal mover 3 comes into close contact with the third measurement unit 130. Then tighten the fastening means (6) to secure.

In this state, it is checked whether the flange height measuring point 3a of the longitudinal mover 3 refers to 25 of the scale of the longitudinal ruler 1e, and the wear and gauge error of the longitudinal mover 3 are examined.

Finally, as shown in FIG. 4, the guide nut 4 fastened to the horizontal ruler 2 of the wheel gauge 1 is released so that the horizontal ruler 2 closely adheres to the side of the block gauge template 100. Tighten the next guide nut (4) to fix it.

Then, after slightly loosening the fastening means 124 fastened to the sons 122, the sons 122 are moved downward to abut on the upper end of the horizontal ruler 2.

In this state, it is examined whether the flange thickness measurement point 2a of the horizontal ruler 2 refers to 34 of the scale of the horizontal ruler 1b of the wheel gauge 1.

And it is checked whether the horizontal ruler 2 exactly touches the reference scale 125 and the measurement position of the horizontal ruler 2 is correct.

Then, check whether the first division part 121b and the second division part 122b coincide with each other to check whether the height of the horizontal ruler 20 is correct, and whether the reference point 123a matches the reference line of the second division part 122b. Check and measure the error.

If the reference point 123a is higher than the reference line of the second division portion 122b, the Hurenji thickness is thinner than the stationary number, and if the reference point 123a is lower than the reference line of the second division unit 122b, the flange thickness is greater than the stationary number. It comes out thick.

As described above, according to the wheel gauge inspection block gauge of the present invention, by easily fixing the wheel gauge (1) to be measured in the slide groove 101, anyone who is not skilled in the art can inspect the wheel gauge (1) accurately and easily It is convenient to be able to do it.
