Description

The present invention relates to an inclination angle measuring device for confirming an inclination in order to adjust the section insulator to a horizontal state in the left-right direction at the time of installation, replacement, etc. of a section insulator connecting adjacent sections of a train line.

If the section insulator is twisted due to the habit of the trolley wire or the like and the vertical angle is inclined in the left-right direction, the contact force of the pantograph becomes non-uniform on the left and right, and the insulating member becomes uneven. In order to prevent this one-sided slip, it is necessary to adjust the section insulator horizontally, but if the adjustment is insufficient, the insulating member or the whole must be replaced due to the one-sided slip.
Conventionally, a spirit level is configured by exposing a bubble tube containing liquid and bubbles to the surface and fixing it to the body, and applying it to the measurement surface to be measured, and depending on the bubble position of the bubble tube, the levelness or verticality of the measurement surface. Is visually confirmed (Patent Document 1). When adjusting the tilt angle of the section insulator using this level, batten the section insulator to make a flat surface, place the level on the batten to check the tilt, and remove it. After that, the twist of the trolley wire is corrected. Since this adjustment work installs a batten and a spirit level every time the twist of the trolley wire is adjusted and visually checks it, it becomes a troublesome work in which the angle check and the twist adjustment are repeated alternately, and the work efficiency is improved. It is bad and the work load is heavy.

Therefore, an object of the present invention is to provide an inclination angle measuring device that can be easily and relatively accurately confirmed while adjusting the inclination angle of a section insulator.

In order to solve the above problems, the inclination angle measuring device 1 of the section insulator S of the present invention measures the inclination with respect to the horizontal in the left-right direction when the section insulator S is installed. The tilt angle measuring device 1 displays angle scales 6 at predetermined intervals in an arc shape in the left-right direction with a position vertically below a specific reference point as the origin on the surface of the trolley line T in the direction orthogonal to the extension line. A pointer 5 that is rotatably pivotally supported at a specific reference point of the panel 4 and the display panel 4 and hangs vertically downward from the reference point by its own weight to indicate an angle scale 6, and an insulating member S1 of the section insulator S. Hooks 3 for hooking to arc horns S3 fixed to both sides of the connection fitting S2 connected to the trolley wire T are provided at the upper ends, and the reference point of the display panel 4 is located on the extension line of the intermediate point of these hooks 3. It is provided with mounting arms 2a and 2b that support the display panel in such a posture. When the mounting arms 2a and 2b are mounted on the section insulator S, the scale 6 on the display panel 4 pointed by the pointer 5 indicates the inclination of the section insulator.

The inclination angle measuring device of the section insulator of the present invention will be described with reference to the drawings.
In FIGS. 1 to 8, the inclination angle measuring device 1 includes a pair of left and right mounting arms 2a and 2b having hooks 3 at the upper ends, and a display panel 4 supported below the mounting arms 2a and 2b. It is provided with a pointer 5 that points to a scale on the display panel 4.

One of the pair of mounting arms 2a facing the left and right has a base portion that continuously rises forward at a substantially right angle from the one-sided edge portion of the upper portion of the display panel 4 and extends upward. The other 2b of the mounting arm extends upward with its base connected to a mounting piece 4a whose base is continuously raised at a substantially right angle forward to the other edge of the upper part of the display panel 4. The mounting arm 2b is provided with a long hole 2d in the vertical direction for inserting a screw 2c penetrating the insertion hole 4b of the mounting piece 4a, and the length is adjusted by changing the relative position vertically with respect to the mounting piece 4a. Provide a possible length adjusting means. The mounting arms 2a and 2b are made of steel plates, and the upper half thereof is wider than the lower half to secure a stable width in the extending direction of the hook 3 at the upper end. The hook 3 is an arc in which the upper ends of the mounting arms 2a and 2b are folded back inward in a U-shape so as to face each other, and the insulating member S1 of the section insulator S is fixed to both sides of the connecting metal fitting S2 for connecting the insulating member S1 to the trolley wire T. It is formed in a substantially U shape so as to be hooked on the horn S3. The mutual distance between the mounting arms 2a and 2b is set so widely that the section insulator S can be received from the lateral direction and can rotate in the direction orthogonal to the extension line without expanding between the mounting arms 2a and 2b.

The display panel 4 is made of a trapezoidal steel plate that extends downward at the bottom of the upper half of the rectangle. The lower edges of both sides of the display panel 4 are provided with an arc-shaped angle scale 6 that bulges downward at equal intervals to the left and right from "0" degrees, which is the origin representing the horizontal of the central portion. An arc-shaped slit 7 that bulges downward in the lateral direction is provided above the angle scale 6. A transparent cover 10 having the same shape and size as the display panel 4 is fixed to the front and rear sides of the display panel 4 in parallel with a collar 10b at intervals by a plurality of screws 10a.

The pointer 5 is composed of a pair facing each other on both front and rear sides of the display panel 4. These pointers 5 are rotatably centered on the upper end portion of the upper end portion, which is a specific reference point of the display panel 4 located on the extension line of the intermediate points of the hooks 3 and 3 of the mounting arms 2a and 2b, respectively. Axis is supported. The pointer 5 faces vertically downward due to its own weight, its tip is located on the angle scale 6 of the display panel 4, and indicates the angle at which the display panel 4 is tilted together with the section insulator S. The lower ends of both pointers 5 and 5 are joined and integrated by a connecting screw 9 that can move through the slit 7 of the display panel 4.

When adjusting the horizontal posture of the section insulator S using this angle measuring device 1, the angle measuring device 1 is held in a lateral position tilted by 90 °, and the section insulator S is received from the side between the mounting arms 2a and 2b. Hook the lower hook 3 of the angle measuring device 1 in the sideways state on the arc horn S3 on the back side of the angle measuring device 1, and rotate the arc horn S3 about 90 ° in the direction orthogonal to the extension line to the front. Hook the other hook 3 on the arc horn S3. If the section insulator S is mounted horizontally in the left-right direction, the pointer 5 points to "0" on the angle scale 6 of the display panel 4 located vertically below the section insulator S. Further, if it is tilted up and down in the left-right direction, the pointer 5 indicates the tilt angle of the angle scale 6 of the display panel 4 located vertically below. Therefore, the twist of the trolley wire can be adjusted with a tool while looking at the angle scale 6. After the adjustment, when the angle measuring device 1 is rotated around one of the arc horns S3 on which one of the hooks 3 is hung in the direction orthogonal to the extension line, the hook 3 hung on the other arc horn S3 comes off on the way. If the angle measuring device 1 is tilted 90 ° and the other hook 3 is removed in a lateral position, the angle measuring device 1 can be separated from the side of the section insulator S. The length of the mounting arm 2b can be adjusted according to the difference in the vertical position of the left and right arc horns S3 of the section insulator S by changing the screw 2c fixing position up and down within the range of the elongated hole 4b of the mounting piece 4a.
