Description

  The present invention relates to a branching device at a rail branching point used in railways, and more particularly to a branch having a track short-circuit prevention structure.

  A special branching device such as a double slip switch (DSS) has a complicated structure as compared with a normal branching device. For example, if the left and right slip rails come into contact with each other at a point equipped with a DSS, a phenomenon may occur in which an unexpected track short circuit occurs because the polarities of the left and right rails on the track circuit are different. And once a signal malfunction occurs due to this track short circuit, a great deal of labor is required for safety confirmation.

  Since all the parts constituting the point are formed as a single body, they are conducted even with a slight contact. The cause of the track short-circuit is not only the mutual contact of the Tongrel, but also the mutual contact by the parts (for example, the rolling rod, the connecting member mounting bolt, the elbow bracket, the elbow bracket mounting bolt) attached to the Tongrail. It may occur at various points such as contact between parts and basic rail.

For example, this contact may be caused when rail advancement, sleeper interval, rightward movement of the sleeper, orbital displacement, etc. occur beyond the limit or compete with each other. Further, as a mechanical problem, there is a case where a signal comes in contact with a temporary contact during the slip point change. This is because the rear Tongleil starts to convert first due to the timing of adjusting the left and right switch adjusters or the characteristic that the Tonglele at the elastic point tries to return to the center of the stroke by the restoring force.

Of these protrusions 13 and 14, the protrusion 13 provided on the second Tongrel 4 b protrudes in the direction of the first Tongler 3 a, and the protrusion 14 provided on the first Tongrel 3 a is the second Projecting to the Tongrel 4b side. And between these protrusions 13 and 14, it sets to the minimum magnitude | size which can ensure the operation | movement stroke of the 1st tongrel 3a and the 1st tongrel 4b at the time of point switching.

  At the point configured as described above, the rail 12 on the other side of the first track, the rail 22 on the other side of the second track, the first Tongler 3b, the second Tongler 4b, the adjuster rod 7, And the arm brackets 8 and 9 are directly connected to the rail 12 on the other side, the rail 22 on the other side, the first tongrel 3b, the second tongrel 4b, the adjuster rod 7 and the arm brackets 8 and 9. Is electrically homopolar. In addition, the rail 11 on one side of the first track, the rail 21 on the other side of the second track, the first tongrel 3a, and the second tongrail 4a are directly connected (not shown). The rail 11 on one side of the first track, the rail 21 on the other side of the second track, the first Tongler 3a, and the second Tongler 4a are electrically identical in polarity.

As the first rolling rod 5 and the second rolling rod 6 are driven, the first tongley 3a and the coupling connected to the second rolling rod 6 by the coupling member 16 The second tongrel 4b connected to the first rolling bar 5 by the member 17 moves in the gauge direction, and the path can be switched.

  At the time of such switching, the protrusion 14 provided on the connecting member 16 of the first Tongrel 3a and the protrusion 13 provided on the connecting member 17 of the second Tongrel 4b are connected to the first Tongrel 3a and the first Tongrel 3a. Since the two tongrels 4b come into contact with each other before they come into contact with each other, it is possible to avoid contact between rails having different polarities. And since each processus | protrusion which mutually contacts is electrically neutral and is insulated with respect to each rail, conduction | electrical_connection by a contact, ie, a track short circuit, does not generate | occur | produce.

  For example, the dimensions of the protrusions provided on the connecting member 16 and the connecting member 17 are designed such that the distance between the protrusions of both the connecting members 16 and 17 is narrower than the shortest distance between the other members. When an error such as rail travel ± 15 mm is included, the design gap between both protrusions can be set to 10 mm, and a minimum gap of 2.4 mm at the time of contact between both protrusions can be ensured.

  The connecting members (15 to 18), the connecting portions 5a and 5b of the first rolling rod 5 and the connecting portions of the second rolling rod 6 are connected by pins (19 and 20). It is also effective to eliminate the dismantling work.

  Furthermore, it is also effective to provide a device for preventing the tongrel from jumping up by the insulator on the first rolling rod 5 and the second rolling rod 6.

  Furthermore, it is designed so that replacement parts from the already installed DSS are minimized.
