In the coke oven configuration, the extruder, guide car, and fire extinguishing car are placed in the corresponding furnace chamber where the raw coal is charged and fired sequentially by the charging car into each of the furnace chambers in the coke oven configuration. When the red hot coke fired by the extruder is extruded, the fire extinguishing vehicle is moved in synchronization with the extrusion speed, and the fire extinguishing vehicle is opened and closed. On the car with the door closed, red hot coke is loaded and received, and after loading is completed, the fire extinguishing vehicle is moved toward the fire tower and stopped accurately at a predetermined position in the fire tower, and Water from the tank tank on the tower in a state where the fired red hot coke was sprayed to extinguish the fire, and after draining it sufficiently, the fire extinguishing truck was then moved toward the coke wharf and moved to the specified wharf location. Stop accurately before the opening, then open the door and wholesale the extinguished coke on the predetermined wharf location and discharge it, thus ending the kiln receiving work in this way, and thereafter, this work Is repeated sequentially for each furnace chamber to continuously execute required kiln discharge.

[Problems to be solved by the invention]

By the way, regarding the operation of the coke oven fire extinguishing car, the interrelation between the guide car and other working machines such as an extruder is extremely important in the work, and therefore, usually, a wired or wireless telephone is used. It is necessary for workers in the respective places to communicate with each other using communication means, and to proceed with the work while checking the work state, work position, etc. of each work machine one by one.

However, in such a manual and manual driving operation based on mutual communication between workers, false reports are likely to occur due to misunderstandings, and it is not always possible to accurately grasp the work state, work position, and the like. There is a problem.

Therefore, conventionally, means for automatically controlling the operation of each of the working machines such as the extruder, the guide car, and the fire extinguishing car has been proposed. The total weight of the fire extinguishing vehicle and the electric vehicle towing the fire extinguishing vehicle is considerably large (for example, the self-weight of the fire extinguishing vehicle is 55t, the own weight of the electric vehicle is 35t, the total weight 90t), the load weight on the track surface is large, and the relative positional relationship of the track surface with respect to the furnace body, fire tower, coke wharf, etc. tends to fluctuate. In such a case, effective automatic control cannot always be achieved.In order to withstand such an excessive load weight, a sufficient concrete foundation structure is applied to increase the track floor strength. There must, were those that require a lot of foundation work cost.

[Action]

Therefore, in the device of the present invention, a traction system using a winch device via a wire rope is adopted for the traveling operation of the fire extinguishing vehicle traveling on a predetermined track surface. Only the empty weight of the car, or the load on the track surface, is applied, and the load weight on the track surface can be significantly reduced. In addition, the fire extinguishing vehicle with the door kept closed by the door opening / closing actuator is expected. After receiving the fired coke and extinguishing the fire, when the fire extinguishing vehicle position detecting means detects that the fire extinguishing vehicle has stopped positioning at the designated wharf position, the detection signal activates the door opening / closing command actuator to open / close the fire extinguishing vehicle. By switching the switching valve, the coke can be satisfactorily and effectively discharged to the designated wharf portion by opening the opening / closing door and eventually.
