Done.

At this time, the traffic light support 225 is also interlocked with the advancing, it is to support the separated traffic light 30 while being inserted into the second locking hole (32).

In this state, when the detachable performing unit 220 is lowered according to the driving of the lifting operation unit 230, the traffic light 30 is completed by the horizontal support 20 while being separated from the horizontal support 20 while being supported by the traffic light support 225.

On the contrary, when engaging after maintenance, if the detachable execution unit 220 is raised in accordance with the driving of the lifting operation unit 230, as shown in (a) of FIG. 8, the locking plate of the coupling separation arm 240 ( 244 is located at the rear of the pin operating table 23, when the moving frame 223 moves backwards in this state, the coupling separation arm 240 is interlocked backwards in conjunction with the pin operation as shown in FIG. Pull the base 23 to allow the fastening pin 22 to be locked to the first catching hole 31 again.

And when the locking is completed and the pin operating platform 23 is in a state that can not be pulled, since the rotational force greater than the restoring spring 245 is generated in the rotation locking plate 244, as shown in (c) of FIG. The upper part of the rotation locking plate 244 is pushed and rotated, and finally, the pin operating part 23 is returned to its original state.

Of course, at this time, as the reverse of the moving frame 223 can be understood that the traffic light support 225 is also separated from the second catching hole 32 which was supported while reversing.

On the other hand, the traffic light support 225 for supporting the traffic light 30 is separated from the horizontal support 20 as described above is provided with a fall preventing means 250 for preventing the departure of the traffic light due to the weight or external impact of the traffic light Can be.

As the wedge member 254 is downward, it can be easily inserted without being caught.

After the insertion, as shown in FIG. 10 by raising the wedge member 254 while the operation rod 251 is returned to its original position by the restoring force of the spring 253, the release catching jaw 254b of the wedge member 254 is shown. The second catching hole 32 is caught so that the separation can be prevented.

When the signal light support 225 is to be detached again, power is applied to the solenoid 252 to move the manipulation rod 251 backward. Then, since the wedge member 254 is lowered by its own weight, the catch of the detachment catching jaw 254b is released so that the traffic light support 225 can be easily exited from the second catching hole 32.

On the other hand, the detachable towing actuator 200 according to the present embodiment detects the operating state of the main moving unit 210, detachable performing unit 200, elevating operation unit 230 of the control box 216 or the ground It is possible to further include a variety of sensing switches for transmitting a signal to a separate remote controller or the like to automatically control the driving or to be recognized by the operator on the ground.

That is, before the maintenance work of the traffic light 30, the worker on the ground checks the position of the traffic light 30 requiring maintenance among the plurality of traffic lights 30 fixed to the horizontal support 20 and is assigned to the corresponding position. The protruding length of the stop setting pin 274 may be adjusted in advance so that the stop setting pin 274 may be caught on the position identification table 271. Accordingly, the traction movement is detected when the corresponding traffic light 30 is reached. Detection of the switch 261 is to be made.

Looking at the configuration according to an embodiment of the present invention as described above, the operation is briefly described as follows.

First, when maintenance of the traffic light 30 is required as shown in FIG. 1, the detachable towing actuator 200 is horizontally moved toward the traffic light 30.

In the horizontal movement, when the traction drive motor 213 is driven first, the moving wheel 212 is rotated by the driving force, and thus the moving wheel 212 is the horizontal rail part 120 of the guide rail 100. ) And the slider 211 is supported by the vertical rail portion 110 of the guide rail 100 to perform a sliding movement.

And when the horizontal movement toward the traffic light 30 in this way, the detachable execution unit 220 is kept in a lowered state, accordingly there is a fastening structure, such as other traffic lights, traffic signs or road guide plate on the movement route Even if it does not interfere with these structures it is possible to easily move horizontally to the position of the desired traffic light.

In addition, in the horizontal support 20, a plurality of reinforcing wires 40 for preventing sagging of the horizontal support 20 due to its own weight may be connected to the upper end of the horizontal support 20 to act as an obstacle for parallel movement. , The detachable towing actuator 200 is moved along the guide rail 100 spaced apart from the rear of the horizontal support 20 by a predetermined distance irrespective of the reinforcing wire 40, so that the reinforcing wire 40 is affected. It can be seen that the horizontal movement can be easily performed without receiving.

When the detachable towing actuator 200 reaches the maintenance target signal light 30 by driving the traction drive motor 213 as described above, the detachable execution part 220 is driven by the driving of the lifting drive motor 233. It rises to the position of fastening structure of 30).

Then, the coupling separation arm 240 is advanced by the driving of the horizontal drive motor 224 to release the fastening of the traffic light, and at the same time the traffic light support 225 is coupled with the traffic light 30 to stop the traffic light 30. Will be supported.

At this time, since the traffic light 30 is supported by the fall preventing means 250 provided in the traffic light support 225 as described above, even if a flow or vibration occurs during the towing process, the traffic light 30 falls down, such as a safety accident. It can be seen that there is no concern.

When the separation and the support of the traffic light 30 is completed in this way, the lifting driving motor 233 is driven again to detach the traffic light 30 from the horizontal support 20 by completely lowering the detachable execution part 220 (FIG. 10). Reference)

Then, by the driving of the traction movement driving motor 213, the detachable towing actuator 200 supporting the traffic light 30 is horizontally moved to the support side so that the support side traction of the traffic light 30 is made. (See Figure 11)

On the other hand, the combined process after the maintenance of the traffic light 30 is carried out in the reverse order of the above process, the detachable towing device 200 for supporting the traffic light is completed to pull the traffic light again to the original traffic light from the holding side After the horizontal movement is completed, the horizontal movement is completed, the detachable execution unit 220 is raised to enable the fastening of the traffic light, and after the completion of the coupling separation arm 240 and the traffic light support 225 is moved to the rear Again, the traffic light 30 is coupled to the horizontal support 20.
