It is installed on the coaxial shaft 20, the electromagnet 31 is installed on the driven shaft 21, and when energized, the armature 30 moves against the force of the spring and attaches to the electromagnet 31. The coaxial 20 and the driven shaft 21 are connected, and at the time of non-energization, the armature 30 is separated from the electromagnet 31 by the force of the spring, and blocks the coaxial shaft 20 and the driven shaft 21.

In addition, as shown in FIG. 4, the proximity shaft 20 and the to-be-detected part 25a are provided in the main shaft 20, and the proximity switches 32 and 33 are provided in the periphery of the proximity switch panel 25. As shown in FIG. . These proximity switches 32 and 33 are switches for opening and closing the drive circuit of the gear motor 9 by detecting the detected portion 25a.

When the stopper rod 2 shown by the broken line in FIG. 4 rises and becomes vertical, the gear motor 9 is detected by detecting the detected part 25a shown by the solid line in FIG. 4 and transmitting a detection signal. After that, the open state of the stopping rod 2 is maintained by a mechanical brake (not shown) of the gear motor 9.

On the other hand, when the stopper rod 2 shown by the broken line of FIG. 4 is lowered and becomes horizontal, the gear motor 9 transmits a detection signal by detecting the detected part 25a shown by the double-dotted line of FIG. ), And then the closed state of the stopping rod 2 is maintained by a mechanical brake (not shown) of the gear motor 9.

When the stopper rod 2 is rotated horizontally, the stopper arm 24 touches the stopper (not shown), and the stopper rod 2 stops reliably in a horizontal state. When it rotates to become vertical, the stopper arm 24 touches another stopper which is not shown in figure, and the stopper bar 2 stops reliably in a vertical state.

When the stop bar 2 is stopped while the stop bar 2 is in a horizontal state, the electromagnet 31 cuts off and the clutch 22 is cut off, and the driven shaft 21 becomes free, and the stop bar 2 ) Rotates upward by the return spring to open the doorway of vehicle C.

Thus, even if the operation of the stopper rod 2 by the gear motor 9 becomes impossible due to the blackout, the stopper rod 2 automatically rises, so that the vehicle C is not stopped by the breaker 1.

11 and 12, the control unit 16 is connected to the two breakers (1, 1) by wireless or wired, these two breakers (1, 1) is one side of the road construction site 13A It is provided at the entrances 14 and 15 of the shift passage control area 13, respectively. The controller 16 controls the state monitor signal of the vehicle sensors 6 installed in the two breakers 1 and 1 and the second vehicle sensors 17 installed 15 m to 30 m apart from the breakers 1 and 1 along the road. The vehicle presence data is processed, and appropriate signals are sent to the driving circuit of the stopping rod 2 of the breakers 1 and 1 and the signal circuit of the signaling device 4 to open and close the blocking rod 2 and to operate the signaling device 4. The blue and red lights alternately flash.

That is, when the vehicle sensor 6 and the second vehicle sensor 17 of the down-vehicle C circuit breaker 1 detect the down-vehicle C which is stopped for waiting in the state where one side of the up-vehicle C is made to pass, this vehicle is detected. Based on the detection signals of the sensor 6 and the second vehicle sensor 17, the control unit 16 determines that a predetermined number of downward vehicles C are waiting between the vehicle sensor 6 and the second vehicle sensor 17. At the same time as closing the stopping rod 2 of the breaker 1 for the up-vehicle C, a command signal for switching the signal 4 of the breaker 1 to a stop signal (red light) is transmitted. Then, the control unit 16 opens the blocking rod 2 of the breaker 1 for the downward vehicle C at the time when all of the upstream vehicle C passing through the one shift control region 13 passes the same region 13. In addition, a command signal for switching the signal of the signal breaker 4 of the circuit breaker 1 to a progress signal (blue light) is sent to advance the waiting vehicle C that is waiting. The controller 16 repeats the above-described control to alternately pass the uplink vehicle C and the downlink vehicle C alternately through one of the alternating traffic control zones 13.

In addition, by adjusting the distance between the vehicle sensor 6 and the second vehicle sensor 17, it is possible to control according to the progress of the vehicle C. That is, narrowing the interval can cope with a time when the number of progresses of the vehicle C, such as night, is small, and widening the interval can cope with a time when the number of progresses of the vehicle C is high.

In addition, the control part 16 is not limited to the said control content. For example, it is good also as control content which switches the signal of the signal signal 4, and opens and closes the stop rod 2 according to the signal switching time of the signal signal 4 previously set, and the opening / closing time of the blocking rod 2. As shown in FIG.

In addition, the breaker 1 is operated by a state bar of a stop rod bend detection sensor (not shown) which detects the break of the stop rod 2 and a state switch of an obstacle sensor other than the figure which detects the obstacle, and thus the state signal of the state switch. Is transmitted to the control unit 16, the operation is performed based on the command signal from the control unit 16, and the signal of the operation status is returned to the control unit 16. The vehicle C up and down can be alternately made to flow smoothly without stalling the vehicle C.

The obstacle sensor detects an obstacle that is an obstacle of the closing operation of the stopping rod 2, in particular, a vehicle C entering. The control unit 16 receives the obstacle detection signal of the obstacle sensor and moves the blocking rod 2 during the closing operation to the open operation, and when the obstacle sensor does not detect the obstacle, the vehicle sensor 6 and the second vehicle described above. The number of vehicles is judged by the vehicle detection signal of the sensor 17, and the signal C of the signal is switched and the stop bar 2 is opened and closed in accordance with the number of vehicles to proceed without stagnation of the vehicle C.

The breaker 1 is capable of switching between automatic control and manual control with respect to the control of the stop bar 2 and the signal detector 4. As the manual control, either a fully passive type or a semi-passive type may be adopted. The fully manual type controls the opening and closing of the stop bar 2 and the movement of the signal of the signal unit 4 by manual remote control operation at the eyes of the person in charge, and is mainly used in an emergency. Semi-passive type is one of two circuit breakers (1) is a mosquito (main body) by a person in charge to control by manual remote control by eye judgment, another breaker (1) is linked to the operation of the mosquito mainly It is used when the work site is complex and there are many construction vehicles.
