2. Description of the Related Art FIG. 3 is a block diagram of a conventional tip locking device for a branching device. Here, 1 is a rolling machine, 2 is a locking lock, 3 is a basic rail, 7 is a tongue rail, 8 is a front rod, 15 is a front rod elbow, 16 is a connecting rod, and 17 is a rolling rod. , 18 is a switch adjuster, 1
9 is a motion. In the railroad turnout conversion lock, the switch adjuster 18 connected to the rolling rod 17 connecting the right and left tongue rails 7 is connected to the operating rod 19 of the rolling machine 1 directly or through cranks, Conversion is performed by moving the operating rod 19 of the rolling machine 1, and when the conversion is completed, the operating rod 19 is mechanically locked in the rolling machine. On the other hand, at the position of the tip of the tongue rail, the front rod 8 attached to the tip of the right and left tongue rail 7 is connected to the lock can 2 which is the tip locking mechanism of the rolling machine 1 via the connecting bar 16. When the conversion is completed, the lock can 2 is mechanically locked by the lock piece in the rolling machine. Since the position where the lock can 2 of the rolling machine 1 is attached is fixed, the cutout position of the lock 2 should be in a state in which the direction of change of the tongue rail 7 is correct and it is bonded to the basic rail 3. For example, the lock piece is regularly adjusted by the maintenance engineer so that it can be inserted in the central position of the notch of the lock can 2. In this case, there is a slight gap between the lock piece and the notch of the lock can 2, and the lock piece is inserted into the notch of the lock can 2 even if the positional relationship is slightly misaligned while the gap is acceptable. can do. Therefore, if the tongue rail 7 is turned in the correct direction and is adhered to the basic rail 3, the lock piece is cut into the notch of the lock can 2 when the motion can 19 is locked in the rolling machine. By inserting the lock piece into the notch of the lock can 2, the adhesive state of the tip of the tongue rail is mechanically checked and the lock of the tip of the tongue rail 7 is performed.

[0003]

According to the prior art,
When using a rolling machine to convert and lock a switch with a long tongue rail length, if the outside air temperature changes significantly, the amount of expansion and contraction due to the temperature of the tongue rail will increase and the position of the tip of the tongue rail will move (hereinafter, If the amount of advance exceeds the allowable range, the tongue rail conversion end direction is correct and the basic rail is Even if it is adhered, the lock notch position will be misaligned, and the lock piece will not fit, making it impossible to lock. If it cannot be locked, the train will not be able to pass safely on the turnout, which will cause great social confusion. Therefore, it is necessary to check and adjust the locked state without fail, and the maintenance is a troublesome facility.

The present invention has been made in order to solve the above-mentioned problems. Even if the tongue rail is swollen due to a change in temperature, if the tongue rail conversion end direction is correct and it is adhered to the basic rail. It is an object of the present invention to provide a tip locking device for properly mechanically checking the lock piece for secure entry.

[0005]

According to a first aspect of the present invention, there is provided a connecting device for a tip locking device of a branching device, wherein a slider is connected to a locking can of a rolling machine through a fitting, and a locking can is attached. Attach a guide metal fitting that guides the slider near the position, fit the slider into the guide of the guide metal fitting, and attach the front rod to the tip of the tongue rail or movable rail through the arm rod of the front rod, and attach the slider and front rod to the rail. It is configured to be engaged by a connecting fitting provided with an elongated hole in the moving direction. According to a second aspect of the present invention, in the connecting device for the tip lock of the branch device, the slider is connected to the lock can of the rolling machine through the joint metal fitting, and the guide metal for guiding the slider to the vicinity of the mounting position of the lock can. Attach the slider to the guide of the guide fitting, and attach the front rod through the tongue rail or the armature that has a long hole in the tip of the movable rail in the rail advancing direction, and attach it to the slider and rail advancing direction. The elbow metal provided with the hole is configured to be engaged by the connecting fitting. In addition, it is important to make the width of the elongated hole in the moving direction sufficiently larger than the moving amount of the tongue rail or the tip of the movable rail.

[0006]

When the connecting device for tip locking of the branching device constructed as described above is used, when the tongue rail moves forward, the front rod moves and the position of engagement with the slot changes, but in the direction perpendicular to the basic rail. Since it has almost no effect on the amount of movement of the slider to, it is possible to prevent the locking position of the rolling machine from shifting. Therefore, if the conversion end position of the tongue rail is correct and it is in a state of being adhered to the basic rail, it can be correctly inspected by the lock piece of the rolling machine, and the lock can be reliably performed.
