Description of the Related Art In a level crossing breaker, a large load moment is generated due to the mass of a level crossing cut-off rod for cutting off a level crossing road. . Therefore, in a conventional level crossing breaker, a motor equipped with weights (hereinafter abbreviated as “weight”) is provided by providing a bar (hereinafter abbreviated as “weight”) in order to provide a function as a balancer for the level crossing rod on the rotating shaft of the level crossing rod. The output has been reduced. However, when a weight is used, a large installation space is required, and when installing in a snow-covered area, the weight needs a cover for snow protection.

ができないという問題点があった。It is desirable that the residual balance be constant irrespective of the rotation angle of the crossing rod 55, but in the case of the weight system, the balancer I (-) shown in FIG. ). The railroad crossing rod 55 used for the railroad crossing cutoff machine has a variable mass and length. Therefore, in order to obtain a balance force suitable for each crossing rod, the amount of eccentricity of the spring fulcrum 58 must be variable. However, in order to reduce the amount of eccentricity corresponding to a lightweight crossing rod,
It is necessary to make the 56 a cantilever support structure, and as a result, there is a problem in that it is not possible to provide shaft ends for mounting a crossing rod at both ends of the rotating shaft 56.

たようなものになる。In the above, the eccentric amount of the spring fulcrum 28 can be changed to zero by using the second rotating shaft 25 as a cantilever support structure, so that it can be applied to the crossing rod 15 in a wide range. . Moreover, shaft ends for mounting the level crossing rod can be provided on both sides of the mechanism of the circuit breaker. Also,
The balancer characteristics can be improved by making the length a of the link 17 and the length b of the link 23 constituting the link mechanism unequal so that a> b. That is, since the links 17 and 23 have unequal lengths as described above and the rotating shaft 16 and the second rotating shaft 25 have unequal speeds, the residual balance can be made more uniform and smaller. As a result, it is possible to reduce the output of the motor 3 that drives the railroad crossing rod 15 up and down. When the lengths of the links 17 and 23 are equal, the rotations of the rotation shaft 16 and the second rotation shaft 25 are equal. In this case, the balancer characteristics are the same as those of the conventional system (the balancer I in FIG. 5). By making the lengths of the links 17 and 23 unequal as described above, the rotation ratio and the torque transmission ratio between the rotating shaft 16 and the second rotating shaft 25 are 1: 1.
Not. An example in which this property is used to improve the balance characteristic is as shown in FIG. 5 as “Balancer II”.

Can be achieved. Also, by using the ball screw shaft 6 for the drive transmission mechanism from the motor 3 to the rotary shaft 16, the number of parts can be reduced as compared with the conventional multi-stage gear train type rotation transmission mechanism, and the lubrication and maintenance of the mechanism can be reduced. Can be reduced. Further, since the mounting position (the amount of eccentricity) of the spring fulcrum 28 can be changed, it can be adapted to the railroad crossing rod 15 having various masses and lengths.

Can be provided. Therefore, it is possible to mount the railroad crossing cutting rod to both shaft ends. According to the second aspect of the present invention, since the rotation axis and the second rotation axis are further unequal, the residual balance can be made more uniform and small, and the crossing rod can be driven up and down. There is an excellent effect that the output of the motor can be reduced.
