<p>The present invention relates to a jig device for fixing a bridging of railway train wheels. The objective of the present invention is to accurately and firmly fix a train, which stops for a long time in a sloped rail or inside a railroad station, thereby preventing accidents, such as collisions between trains or train derailment, for protecting valuable lives and property. The jig device includes turnbuckles (200, 210) equipped with screw threads, which are opposite to each other in the right and left sides; a ground plate (100), which is combined to the jig device in order to support the turnbuckles in both ends; and a bridging (30), which is installed below a train wheel in the right and left side. The ground plate (100) is in contact with both ends of the bridging (30). When a clamping unit (200) of the turnbuckles is rotated, tension is delivered to the screw threads opposite to each other so that the bridging (30) can be tightly inserted between the train wheel (10) and the rail (20) for the bridging to be stably installed and fixed. In addition, an emitting unit is equipped inside the ground plate, which has a handle with protrusion units formed on the inner surface of the ground floor.</p> |
