Description

Portable measuring device for correcting a deviation of a trolley line in electric railway

The present invention relates to a laser deflection measuring apparatus, and more particularly, to a portable deflection measuring apparatus capable of measuring the deflection and height of a trolley line for supplying power to a mobile device using a plurality of laser pointers. will be.

In general, a trolley wire refers to supplying electric energy as a power source by friction with an upper end of a pentagon graph of a mobile device whose main movement is a place movement using electric power such as a train, an electric locomotive, a crane, and the like. In particular, trolley lines used in electric trains and electric locomotives, etc. are hypothesized to have a certain deviation and height specified in the electric railway facility regulations.

The trolley line is installed at a height of 4850 mm to 5400 mm on the upper surface of the railroad rail, and is arranged in a zigzag shape with a deviation of 250 mm left and right at the center of the railroad rail.

However, the above-described trolley line has a problem in that the height and the deviation change due to the long time operation of the tram and the electric locomotive and the line repair work, thereby bringing about a problem in the tram and the electric locomotive.

A conventional biasing device used to solve this problem is shown in FIG.

Referring to FIG. 3, the conventional biasing device 10 includes a flat body 12. The lower end of the body 12 is equipped with a plurality of wheels 14 that can move along a rail consisting of a double line. In the center of the body 12 is formed a vertical rod 18 having a guide hole 16 therein. The vertical rod 18 extends upwardly perpendicular to the body 12. The gauge 20 is inserted into the guide hole 16 so as to be transported up and down. On the upper end of the measurer 20 is formed a horizontal plate 22 capable of measuring the deviation. A scale is formed on the top surface of the horizontal plate 22 so that the deviation can be measured, and a hook 24 is attached to the center of the horizontal plate 22. At the lower center of the horizontal plate 22 is formed an extension rod 26 extending downwardly perpendicular to the horizontal plate 22. The outer circumferential surface of the extension rod 26 is formed with a scale for measuring the height.

The measuring device 10 moves to a place to be measured using a vehicle and places a plurality of wheels on the top surface of the railroad rail. And a plurality of worker measuring device 10 is moved to a position to measure the deviation and height. The measuring device 10 thus transported measures the trolley line's deflection and height using a pulley. First, the end of the pulley is hooked to the hook 24 and the horizontal plate 22 of the measurer 20 is in close contact with the bottom of the trolley wire. Pull it upward until it Thus, reading the scale of the horizontal plate 22 in close contact with the trolley line to measure the deviation, the height is measured by reading the scale of the extension rod 26.

However, the above-described measuring device 10 has a problem that the manufacturing cost is put a lot because the volume is large, its own weight is heavy, and a vehicle must be used. In addition, a large number of workers are required to avoid collisions with tanks and electric locomotives when measuring deviations and heights, and there is a problem in that excessive labor costs are input. In addition, when measuring the place where the evacuation places such as tunnels and bridges are narrow, there was a problem that a collision with a train may occur.

The present invention was devised to solve the above-mentioned conventional problems, and an object of the present invention is to provide a portable deviation measuring device capable of measuring the deflection and height of a trolley wire for supplying power to a mobile device using a plurality of lasers. To provide.

The first guide groove 112 extends from one end of the first body 110 to the other end. One side of the first guide groove 112 is formed with a first ruler 120 to measure the deviation. The first ruler 120 has a zero point formed at the center of the top surface of the first body 110 and is symmetrically formed left and right.

The first leg 114 has a first plate 122 extending inwardly along the bottom surface of the first body 110 at one end of the first body 110. At an end of the first plate 122 extending inwardly, a first extension part 124 extending downwardly with respect to the first plate 122 is formed. Similarly, the second leg 116 has a second plate 126 extending inward along the bottom surface of the first body 110 at the other end of the first body 110.

In this case, when the operator reads the first ruler 120 displayed on the upper surface of the first body 110 through the transparent body 140 on which the zero point display unit 144 is formed, the deviation of the trolley line may be measured.

On the other hand, in order to measure the height of the trolley line, the operator first sets an arbitrary reference point so that the light generated by the first laser pointer 134 matches the trolley line. At this time, the operator operates the second laser pointer 136 to adjust the second laser pointer 136 so that the light of the second laser pointer 136 coincides with the reference point. At this time, the second laser pointer 136 is transferred along the second guide groove 142.

When the reference point and the light generated by the second laser pointer 136 match, the operator reads the scale of the second ruler 146 and the distance between the second laser pointer 136 and the reference point and the second laser pointer 136. The height of the trolley line can be measured by converting the angle of inclination of the car.

As described above, the portable deviation measuring device 100 according to the present invention can be manufactured in a small size so as to be portable by reducing the volume, thereby reducing the manufacturing cost. In addition, since the measuring device 100 is small in volume, it is easy to measure a trolley wire at a place where evacuation sites such as tunnels and bridges are narrow.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the present invention without departing from the spirit and scope of the present invention described in the utility model registration claims I can understand that you can.
