It is a cross-sectional view of a state in which the jig is installed, and FIG. 8 is a conceptual view showing an operation of moving between the wing rails in a state in which the nose rail is installed in the conventional auxiliary locking device of the track changer.

The present invention relates to a fixing jig for preventing cracking of an auxiliary locking device for a track changer. Although there are various line changers, the configuration of the present invention has a nose provided between a pair of wing rails 210, as shown in FIG. It is installed in the crossing part made of the rail 220 and is installed in the auxiliary locking device 300 for moving the nose rail 220 to the left and right.

Here, the auxiliary locking device 300 is located between the sleepers constituting the track and is provided to be movable in the direction perpendicular to the wing rail 210 under the wing rail 210 and the load block 310 and the It consists of link arms 320 installed on both sides of the load block 310 to press both sides of the nose rail 220 located in the upper center of the load block 310 .

So, when the driving device moves the rod block 310 to the left and right, the nose rail 220 is completely in close contact with the wing rail 210 by the link arms 320 that press from both sides of the nose rail 220 . will become

That is, in the branching machine other than the crossing part, the tongue rail is provided on only one side of the basic rail and installed so that the tongue rail is attached to and detached from the basic rail by a driving device, whereas in the crossing part, the nose positioned between the wing rails 210 on both sides Since the rail 220 must be in close contact with both the wing rails 210 on both sides, a pair of link arms 320 for pressing both sides of the nose rail 220 are required.

On the other hand, a first link bracket 312 and a second link bracket 314 are respectively formed on both ends of the rod block 310 constituting the auxiliary locking device 300 on which the nose rail 220 is installed. One end of the link arm 320 is coupled.

Here, the first fixing hole 313 formed to penetrate left and right through the first link bracket 312 is formed in a circular shape, and the second fixing hole 315 is formed to penetrate left and right through the second link bracket 314 . is formed as a rectangular long hole, and the coupling part 326 formed at the end of the link arm 320 is provided with a fixing pin 328 so as to penetrate left and right, so that the end of the fixing pin 328 is connected to the first and second ends of the fixing pin 328 . It is inserted into the fixing holes (313,315).

At this time, the diameter of the fixing pin 328 is formed to be the same as the inner diameter of the first fixing hole 313 , so that the link arm 320 installed in the first link bracket 312 is coupled without play, but the second The link arm 320 installed in the link bracket 314 has a certain clearance by the second fixing hole 315 having a long hole shape.

That is, the nose rail 220 is installed on the upper part of the auxiliary locking device 300 , and due to the nature of the place where the nose rail 220 and the auxiliary locking device 300 are installed [the load block 310 as shown in FIG. 8 ] ) moves through the lower space of the wing rail 210, and the link arm 320 is inserted through a through hole formed to penetrate left and right in the wing rail 210 to fix the nose rail 220 in the center] Gap Since installation is impossible without forming the

However, even when the nose rail 220 is in close contact with the wing rail 210 due to this play, a certain amount of play is formed, so that when the railway vehicle runs the crossing, the vibration between the wheel and the nose rail 220 is greater. As a result, a load is added to the structurally weak portion of the link arm 320 that presses the nose rail 220 from both sides, thereby causing cracks.

When exposed to such strong vibration for a long time, there is a problem in that the link arm 320 is damaged around the cracked portion.

Accordingly, in the present invention, the fixing jig 400 is installed on the second link bracket 314 formed on one side of the rod block 310 to prevent play, thereby preventing damage to the link arm 320 .
