[Problems to be solved by the device]

 By the way, in the case of a conventional railroad crossing barrier, after changing the rail, it is necessary to adjust the time to fall or rise due to the weight of the rail as described above, check the operation, etc. There was a problem in that the traffic had to be cut off for the test, which caused traffic congestion.

In view of this, the present invention solves the above-mentioned conventional problems, does not need to test the crossing for a long period of time, does not cause traffic congestion on the crossing, and replaces the crossing rod. It is an object of the present invention to provide a railroad crossing breaker capable of performing work.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is, in the above-described railroad crossing breaker, equipped with a saddle in which a guide protrusion is erected on the upper surface of a stand, and has a guide hole to be fitted into the guide protrusion of the saddle. The rotating member, which is guided by the protrusion and is slidable on the upper surface of the saddle, can be rotated on the lower surface of the upper mechanism portion in the track side direction where the railroad crossing exists and in the track side direction opposite to the railroad crossing. The rotary member and the saddle are fastened together by the fastening member.

[0006]

[Action]

 If the breaking rod is broken, remove the broken breaking rod from the bar holder of the upper mechanism, and then release the fastening with the fastening member to slide the rotating member and the upper mechanism along the lower surface of the rotating member along the upper surface of the saddle. Move it and rotate it from the side of the railroad track where the railroad crossing exists to the side of the railroad track opposite to the railroad crossing. Then, if necessary, a new cutting rod is attached to the bar holder while being temporarily fastened by the fastening member. Then, adjust the time to fall or rise due to the weight of the shutoff rod, and check the operation. After the adjustment and operation check are completed, release the temporary fastening with the cutoff rod attached, and re-rotate the rotating member and the upper mechanism from the side of the track opposite to the railroad crossing to the original railroad crossing. Rotate to the side of the track and fasten the rotating member and saddle with the fastening members.

【Example】

 FIG. 1 is a front view of a railroad crossing breaker according to an embodiment of the present invention, FIG. 2 is a perspective view thereof, FIG. 3 is an exploded perspective view, and FIG. 4 is a sectional view of essential parts. Reference numeral 1 denotes a stand on which a saddle 2, a plate 3 as a rotating member, and an upper mechanism portion 5 are sequentially mounted. A cutoff rod 6 is attached to the bar holder 7 in the upper mechanism portion 5 and is moved up or down between a substantially horizontal position and a substantially vertical position by an electric motor (not shown) when the train approaches or passes. In FIG. 1, an arrow X indicates the up and down movement range, and 8 indicates a weight arm.

The upper flange of the stand 1 and the lower flange of the saddle 2 are fastened with bolts 10. As shown in FIGS. 3 and 4, a shaft bolt 11 as a guide protrusion is screwed into the center of the upper surface of the saddle 2. A wiring hole 12 is formed in a U shape around the shaft bolt 11.

On the other hand, the plate 3 is fastened to the lower surface of the upper mechanism portion 5 with bolts 13. A guide hole 15 is formed in the center of the plate 3 so that the shaft of the shaft bolt 11 can be loosely fitted therein. When the axial bolt 11 is screwed into the saddle 2, it is screwed through the guide hole 15 of the plate 3, so that the plate 3 and the upper mechanism portion 5 are pulled out by the head of the axial bolt 11 and fall out. There is no such thing. Further, in the plate 3 and the upper mechanism portion 5, the lower surface of the plate 3 slides on the upper surface of the saddle 2 through the guide hole 15 guided by the axial bolt 11, and the railroad crossing as shown by arrows B and C. It is possible to rotate over a range of approximately 180 ° in the direction of the side of the railroad track and in the direction of the side of the railroad track opposite to the railroad crossing. The plate 3 and the upper flange of the saddle 2 are fastened with bolts 17. Reference numeral 18 denotes a wiring hole formed in the plate 3, and 19 denotes a wiring cable arranged through the wiring holes 18 and 12.

In the above description, the stand 1 and the saddle 2 are attached with 10 bolts and 4 bolts, the saddle 2 and the plate 3 are attached with 17 bolts and 4 bolts, and the plate 3 and the upper mechanism part 5 are 13 bolts and 4 bolts. Installed.

The operation of this embodiment will be described. The procedure for replacing the breaking rod 6 when it breaks is as follows. First, the broken cutting rod 6 is removed from the bar holder 7 of the upper mechanism portion 5. After detaching, loosen the bolt 17 and remove it, and slide the plate 3 and the upper mechanism part 5 along the upper surface of the saddle 2 through the guide hole 15 guided by the shaft bolt 11 on the lower surface of the plate 3. , Rotate from the side of the railroad track where there is a railroad crossing to the side of the railroad track opposite the railroad crossing. After that, the bolts 17 are temporarily fixed, and a new cutting rod is attached to the bar holder 7 with the bolts 17 temporarily fixed. Then, with the shut-off rod 6 facing the side of the railroad track on the side opposite to the railroad crossing, the time for the shut-down rod 6 to fall or rise due to its own weight is adjusted, and the operation is checked.

After the adjustment and the operation check are completed, the bolt 17 is loosened and removed with the blocking rod 6 attached, and the plate 3 and the upper mechanism portion 5 are again removed from the side of the railroad track opposite to the railroad crossing. Rotate to the side of the track where the original railroad crossing is located. After that, if the plate 3 and the saddle 2 are fastened with the bolts 17, the railroad crossing breaker is restored to a normal usable state. When the plate 3 and the upper mechanism portion 5 are rotated, the lower surface of the plate 3 slides on the upper surface of the saddle 2 while the guide hole 15 of the plate 3 is guided by the shaft bolt 11, so that the rotation is extremely smooth. In addition, even if the plate 3 and the upper mechanism 5 are inadvertently tilted, the head of the shaft bolt 11 prevents the plate 3 from falling off, which is highly safe.

In this example, the plate 3 is used as the rotating member, but a member other than the plate such as the saddle 2 may be used, and the shaft bolt 11 is used as the guide protrusion. However, a pin other than this may be used. Further, although the bolt 17 is mentioned as the fastening member, other members may be used as long as they can be fastened and the like, and various modifications can be made within the scope of the invention when the invention is put into practice.

[0014]

[Effect of device]

 Since the present invention has the above-mentioned configuration, when a breaking rod is broken, a new cutting rod is attached to the bar holder for replacement work, and the dropping time or rising time of the cutting rod is adjusted and the operation is confirmed. It is possible to perform such work in the direction of the side of the track on the opposite side of the railroad crossing. Therefore, during that time, the railroad crossing is not blocked for a long time, and there is an excellent effect that traffic congestion on the railroad crossing, which has conventionally occurred due to the work, can be reliably prevented.
