Description

Technology Field

[0001] The present invention relates to an inclination measuring device for maintenance of a tapered device for a nuclear power plant, and more specifically, to an inclination measuring device for measuring the uniformity of surface inclination when it is necessary to measure the inclination of the outer or inner surface of various devices used in a nuclear power plant. Background Technology

[0003] In general, various devices are utilized in nuclear power plants, and these devices are typically bulky and heavy.

[0004] Therefore, devices such as brackets used to fix or support the aforementioned devices are naturally bound to be heavy and large.

[0005] Therefore, devices and brackets such as the above often have a tapered shape with an inclined outer or inner surface. However, due to the nature of operating under adverse conditions, the surface may become uneven and uneven as the inclined surface wears down or is damaged.

[0006] Ultimately, for the device and the bracket to interlock, the surface slope of the device and the surface slope of the bracket must be the same so that the gap does not widen, preventing gas and contents from leaking through the gap.

[0007] To achieve this, the surface slope of the device and the bracket is measured, and any parts that do not meet the slope are filled in, while any parts that exceed the slope are cut with a grinder or similar tool to minimize the gap when the device and the bracket interlock.

[0008] However, the problem is that since the device and bracket are large in weight and size, it is not easy to measure the inclination of their outer or inner surfaces.

[0009] In addition, no inclination measuring device suitable for maintenance of tapered devices used in nuclear power plants has ever been developed, so it has the disadvantage of having to rely on the operator's eye.

[0025] Hereinafter, preferred embodiments of an inclination measuring device for maintenance of a tapered device for a nuclear power plant according to the present invention will be described in detail with reference to the attached drawings.

[0027] First, it should be noted that identical components or parts in the drawings are indicated by the same reference numerals whenever possible. Additionally, in describing the present invention, specific descriptions of related known functions or configurations are omitted to avoid obscuring the essence of the invention.

[0028] The inclination measuring device (100) for maintenance of a tapered device for a nuclear power plant according to the present invention comprises a coupling part (110) that is movable horizontally along the circular periphery of the tapered device, and a straight ruler (120) that is detachably attached to the coupling part (110) to allow for inclination adjustment, wherein the coupling part (110) comprises a body (110a), a pair of protrusions (111) protruding at the same angle from an imaginary line passing through the center of the body (110a), a straight ruler insertion part (112) formed in the same direction as the imaginary line passing through the center of the body (110a), a straight ruler (120) that is fitted and coupled to the straight ruler insertion part (112), an angle adjustment means formed on the straight ruler insertion part (112) to adjust the angle of the straight ruler (120), and the bottom surface of the body (110a) and A roller (130) is formed on the bottom surface of each of the protrusions (111), and they are all configured to form an isosceles triangle.

[0029] In order for the above-mentioned coupling part (110) to be rotatable while maintaining a horizontal position along the circular periphery of the device having a tapered shape, a roller (130) must be formed on the bottom surface of the coupling part (110). However, the roller (130) is not installed vertically on the bottom surface of the coupling part (110), but is formed horizontally along with the coupling part (110). This is because the rollers (130) formed on the bottom surfaces of the protrusions (111) must be guided and moved along the circular periphery (edge) of the device.

[0030] At this time, the roller (130) formed on the bottom surface of the body (110a), strictly speaking, at the center of the bottom surface of the body (110a), is also formed horizontally like the connecting part (110). This is to ensure that the roller (130) formed on the bottom surface of the protrusions (111) is supported, thereby forming a right angle. In other words, the roller (130) formed on the bottom surface of the protrusions (111) comes into contact with the periphery of the device, and the roller (130) formed at the center of the bottom surface of the body (110a) is placed on a step that forms a right angle with the periphery, so that the body (110a) of the connecting part (110) naturally forms a horizontal position, and consequently forms a right angle with the periphery which is in a vertical state.

[0031] As a result, the connecting part (110) forms a precise right angle as shown in FIG. 4. When a precise right angle is formed by the rollers (130) formed on the bottom surface of the protrusions (111) and the roller (130) formed in the center of the bottom surface of the body (110a), the straight ruler (120) can easily measure the inclination of the outer or inner surface of the tapered shape of the devices.

[0032] Also, after determining and fixing the basic inclination of the straight ruler (120) in this way, if the inclination measuring device (100) of the present invention is moved by pressing the roller (130) located at the front of the circular periphery, it can be immediately determined whether the surface condition of the outer or inner surface of the tapered devices is an inclination that meets the standard.

[0033] That is, if the slope is lower than the standard, it will be formed lower than the bottom of the straight ruler (120), and if the slope is higher than the standard, the straight ruler (120) will be lifted upward at that position, so the difference in slope can be identified.

[0034] As such, for outer or inner surfaces with a slope lower than the standard, workers fill in the material to match the standard slope, and for outer or inner surfaces with a slope higher than the standard, workers grind them down with a grinder or similar tool to match the standard slope.

[0035] As such, the straight ruler (120) serves as a reference for the angle of inclination and must be attached at an accurate position. To this end, the straight ruler insertion part (112) is formed with an insertion groove (112a) into which the straight ruler (120) can be inserted, and the straight ruler (120) inserted into the insertion groove (112a) must be fixed to maintain the corresponding angle by tightening it with an angle adjustment means, namely a bolt (112b) or a bolt and nut.

[0036] In addition, it is preferable that the roller (130) formed on the bottom surface of the body (110a) and the bottom surface of the protrusions (111) be installed to form an isosceles triangle, and in particular, it is preferable that the roller (130) formed on the bottom surface of the protrusions (111) be arranged at an obtuse angle with respect to the roller (130) formed on the bottom surface of the body (110a).

[0037] Additionally, it is preferable that the roller (130) be equipped with a bearing to facilitate rolling motion, and is coupled to the body (110a) and the protrusion (111) by a roller coupling member forming the axis of the roller (130). It is preferable that coupling holes (111a) be drilled in the body (110a) and the protrusion (111) for coupling of these roller coupling members (140).

[0038] At this time, as shown in FIG. 7, an angle gauge may be provided on one side of the straight ruler insertion part (112) to measure the angle of inclination of the straight ruler (120) or to adjust the angle of inclination of the straight ruler (120) according to the angle gauge.

[0039] In addition, for convenience of use, the present invention may be provided with a handle (150) formed vertically on the upper part of the body (110a). In this case, it is preferable that the handle (150) has a structure that allows it to rotate freely.

[0041] As described above, although the present invention has been explained by limited embodiments, the present invention is not limited thereto, and various modifications and variations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the patent claims described below by those skilled in the art to which the present invention belongs.
