Description

Description: TECHNICAL FIELD The present invention relates to an electric turning machine that also uses an escape crank in order to perform switching / locking of a point or movable crossing of a turnout in a railway. is there.

[Prior Art] A point or movable crossing of a turnout in a railway is changed in a traveling direction of a train and fixed (locked) so that it does not move at that position while the train is passing. The roll machine is a device that powers the conversion and locking of this point or the movable crossing.

The rolling machine is a conversion mechanism that linearly moves the operating rod to convert the point, the locking rod that engages by engaging with the rod connected to the tip of the point, and the lock piece is inserted and removed in the notch of the locking rod. It has a locking mechanism. The locking rod has two notches into which the lock pieces are inserted, and the two notches are located at positions corresponding to the point orientation and the point inversion.

When passing a train, the point is always in the orientation or inversion, and the locking rod has the lock piece inserted in the notch corresponding to the orientation or inversion of the point. Therefore,
To switch points, remove the lock piece from the notch of the locking rod (unlock) before the locking mechanism starts conversion, and then the moving rod moves linearly or indirectly by the conversion mechanism. The point is changed to, and when the conversion is completed, the lock piece is inserted into the other notch of the locking rod (locking) to perform a series of operations.

On the other hand, the escape crank is composed of a driving crank and a driven crank.When the operating rod of the rolling machine makes a linear motion, the driving crank connected by a link rotates, and the rollers of the driving crank make the escape surface and the conversion surface of the driven crank. , The other escape surface in that order, the point or movable crossing is converted while pressing the conversion surface.

When converting and locking the point or the movable crossing, one or several escape cranks are installed near the point or the movable crossing separately from the rolling machine, and the rolling machine moves through the escape crank to the point or There is a method to convert and lock the movable crossing. In this case, in the conventional rolling machine, first, the locking mechanism of the rolling machine unlocks the locking rod so that the point or the movable crossing can be freely changed. Then, when the operating rod is operated by the conversion mechanism, it engages with it and the driving crank moves. When the roller of the driving crank moves on the escape surface of the driven crank and passes through the escape surface, it then pushes the conversion surface and the driven crank operates. The point or the movable crossing is converted by engaging with the driven crank, and when the conversion is completed, the roller of the driving crank of the escape crank moves to the other escape surface and stops at a predetermined position. After that, the locking mechanism of the rolling machine moved to perform the locking rod. That is, in the case where an escape crank is also used, if a conventional turning machine is used, the chain out of the time required from the start of unlocking the rolling machine to the completion of locking (hereinafter referred to as the conversion time). There is a drawback that the time required for locking is increased by the time required to move the escape surface of the escape crank.

[Problems to be Solved by the Invention] It is necessary to reduce train arrival time and waiting time in high-density sections of main trunk lines. In order to solve this problem, there has been a strong demand for shortening the conversion time of the turning machine. However, shortening the conversion time of the rolling machine is nothing but increasing the power of the rolling machine.In order to power up with the conventional mechanism, increase the motor capacity of the rolling machine and reduce Need to increase. In this case, the body becomes larger,
In addition, it was necessary to change incidental equipment such as power supply capacity, control device, cable capacity, etc., and it was difficult to realize because the economic impact was great. The present invention is for shortening the conversion time of a rolling machine without changing the auxiliary equipment.

[Means for Solving the Problem] In order to solve the above-mentioned problems, the electric switching machine of the present invention has a structure in which a switch for a branch device is converted through an escape crank (12).
An electric switch having a locking rod (5) for locking and an operating rod (4), wherein the locking rod (5) has locking rod notches (6a, 6b). , The operating rod (4) is a lock piece (7a,
7b), the drive crank (9) of the escape crank (12) is connected to one end of the lock crank, and the lock pieces (7a, 7b) are arranged so as to be orthogonal to the lock rod (5). ) Is engaged with the lock rod notches (6a, 6b), the operating rod (4) moves, and the roller (10) of the driving crank of the escape crank (12) moves to the escape surface (12a) of the driven crank (11). , 12
While moving b), the connecting rod (1
The lock rod (5) is driven through the lock lever (9) to unlock the lock, the operating rod (4) further moves, and the roller (10) of the drive crank (9) of the escape crank (12) moves to the driven crank ( 1
The point (1) is changed by pushing the conversion surface (13a, 13b), and the roller (10) of the driving crank of the escape crank (12) moves on the escape surface (12a or 12b) of the driven crank (11). While locking the lock rod (5), the lock pieces (7a, 7b) are inserted from the notches (6a, 6b) of the lock rod (5) to lock the lock rod (5). It is a machine.

[Operation] When the lock as described above is incorporated in the electric type turning machine and the point or the movable crossing is changed in combination with the escape crank, the operation is performed in the following order.

(1) First, when the conversion mechanism of the rolling machine starts to operate, the operating rod directly moves to unlock the locking machine of the rolling machine and the roller of the driving crank of the escape crank comes off the escape surface.

(2) The roller of the drive crank of the escape crank pushes the conversion surface to operate the driven crank, and the point or the movable crossing engaged with the roller starts the conversion, and then the conversion is completed.

(3) When the conversion is completed, the roller of the driving crank of the escape crank moves from the conversion surface to the other escape surface, and the rolling machine starts locking.

(4) The roller of the drive crank of the escape crank stops on the other escape surface, and at the same time, the rolling machine completes the locking. By doing so, the conversion time can be shortened by the time required to unlock the lock and the lock of the conventional turning machine.

[Embodiment] FIG. 1 shows an embodiment of an electric type rolling machine of the present invention in which a motor is used for power and a ball screw is used for a conversion mechanism to lock and unlock the present invention. The operation will be described with reference to FIG. First
In the figure, when the motor 1 rotates and the operating rod 4 operates via the reduction gears 2a, 2b and the ball screw 3, FIG. 2 (a)
As shown in the figure, the lock piece 7a
Exit through. At the same time, the roller 10 of the driving crank 9 of the escape crank, which is connected to the operating rod 4 by the link 8, passes through the escape surface 12a of the driven crank 11 of the escape crank. Next, as shown in FIG. 2 (b), the roller 10 of the driving crank pushes the conversion surface 13b of the driven crank to move the driven crank 11, and the driven crank 11 rolls through the conversion rod 14 connected to the driven crank 11. Stick 15 works.

The point is composed of two tongue rails 16a, 16b and a rolling rod 15 connecting them, and the rolling rod 15 is a basic rail 17a, 17
When you move in the direction perpendicular to b, the points start to change.
At this time, the locking rod 5 connected by the rod 19 from the front rod 18 connecting the tips of the tongue rails 16a, 16b also moves in the changing direction at the same time. When the conversion of points is completed, the roller 10 of the driving crank enters the escape surface 12b of the other driven crank as shown in FIG. piece
7b starts inserting. When the insertion is completed, as shown in FIG. 2 (d), the limit switch 20b operates to turn off the power of the motor, and the conversion of the rolling machine is completed. The same applies when switching to the other side. Further, as the conversion mechanism, the same effect can be obtained as long as it is a mechanism such as a cam mechanism, a rack and pinion, a hydraulic cylinder, etc., which moves linearly, instead of the ball screw 3.

[Advantages of the Invention] (1) The conversion time can be shortened without changing the power capacity or incidental equipment.

(2) Since a part of the operation of the operating rod locks and a special locking mechanism for operating the lock piece can be omitted,
Can be made compact and can be scaled.

(3) Since the mechanism is simplified and the number of parts is reduced, the reliability of the device is increased.
