Description

  The present invention relates to a front rod connected to a tongrail used in a branching device for selecting a course of a vehicle.

  For example, there is a tipping device described in Non-Patent Document 1 below as a tipping device that bears the point portion of the branching device. This switch device has the structure shown in FIG. 6, for example, and includes a conversion device and a lock device, and is operated by the electric switch 100. Here, the conversion device is for bringing the Tongrel T into close contact with or away from the fixed basic rail R, while the locking device is for maintaining the close contact between the Tongrel T and the basic rail R. It is.

  The electric switch 100 is installed on two sleepers extending outside the gauge (outside between the pair of basic rails R). The electric switch 100 transmits the driving force from the AC motor M, which is a driving source, in the order of a friction clutch, a reduction gear, and a conversion gear with a conversion roller (each not shown), and is operated by the conversion roller 101. Move.

  The motion can 101 moves linearly in a direction perpendicular to the basic rail R as a cam (not shown) connected to the motion can 101 is moved by a conversion roller. The electric switch 100 converts the tongrel T through the switch adjuster 102 connected to the operation cannula 101 and the tie bar 103 connected to the tip end side of the switch adjuster 102, and Whether the tip is in a normal position is checked by the front rod 104, the connecting rod 105, and the locking rod 106. If the front end of the tongue rail T is in a normal position, the operation lever 101 and the locking lever 106 are locked by a cam bar (lock piece) (not shown).

  The front rod 104 disposed between the tips of the tongue rails T has a substantially L-shaped elbow fitting connected to each Tongrel T attached to both ends of the rod portion, and a bracket to which the connecting rod 105 is connected. It is attached in the center. The connecting rod 105 is arranged in parallel to the front rod and is connected to the front rod 104 via a bracket. The positional relationship between the front rod 104 and the connecting rod 105 connected in this way differs depending on the position of the tip of the tongrel T with respect to the connecting rod 105. That is, depending on the type of branching device and the facility location, the tip of the Tongle rail T with respect to the connecting cannula 105 is arranged in front of the connecting cannula 105 (the tip direction side of the Tonglerel T), and the connection as shown in FIG. There is a case where it is arranged behind the can 105 (on the opposite side to the tip direction of the Tongrel T). In the former case, the front rod T connected between the tips of the tongue rails T is connected to the connecting rod 105 in front of the connecting rod 105 (the tip direction side of the tongrail T). In the latter case, the connecting rod 105 is connected. It is connected with the connecting can 105 on the rear side (the direction opposite to the tip direction of the Tongrel) from 105. Therefore, the front rod corresponding to each branching device is selected for each branching device.

  Under such circumstances, the conventional front rod described in Patent Document 1 below can correspond to each branching device by including a mechanism for changing the direction of the bracket. According to this mechanism, the direction of the bracket is changed by reversing the front rod in the horizontal direction, and the front rod can be connected to the connection rod on the front side or the rear side of the connection rod.
