Figures 1 and 2 show an embodiment of the present invention; Figure 1 is a front view showing the normal lowering state of a level crossing barrier with a breakage preventer installed with a motion detector; FIG. 3 is an enlarged front view showing a fixed state. Third
The figure is an enlarged view of the breakage prevention device bent by the shock absorber when a car, etc. comes into contact with the cut-off rod, and the contact of the motion detector is released due to the sliding of the restraining protrusion and the current is cut off. This shows that. Fourth
Fig. 5 and Fig. 5 are schematic diagrams showing the internal mechanism of the bending motion detector, and Fig. 4 shows the state in which the actuating rod is pressed by the restraining protrusion and an electric circuit is constituted by the contact piece and the contact. FIG. 5 is an enlarged front view showing a state in which the pressing force applied to the actuating rod is removed, the actuating rod is projected by the spring, the contact is released, and the electric circuit is cut off. FIG. 6 is a circuit diagram showing the operation (conditions) of each relay for the purpose of alternately flashing the red light of the emergency stop light, as described at the beginning of the configuration. 1...
