Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compressed air generator for a coke oven fire extinguishing vehicle, and more particularly, to compressed air generation in a coke oven extinguishing vehicle driven and driven by wire rope traction means. It concerns the device.

[Conventional technology]

Conventionally, this type of coke oven equipment usually includes a coke oven for firing raw coal in individual furnace chambers arranged side by side, a charging vehicle for charging raw coal into each of the oven chambers, An extruder for extruding the fired red hot coke from each furnace chamber, a fire extinguishing car loading and receiving red hot coke extruded by the extruder, and a red hot coke loaded on the fire extinguishing car And a coke wharf for receiving coke discharged from the fire extinguishing vehicle. A track is laid for each of these parts, and a trolley wire is erected above it. On the track, the fire extinguishing vehicle was towed by an electric vehicle driven and driven by power supply from the trolley wire, and on the fire extinguishing vehicle, the door was opened and closed. Or has an electric air compressor, and the like compressed air tank is mounted as a compressed air source to be used in order to brake stops the extinguishing vehicle itself.

And, regarding the operation control of the fire extinguishing vehicle in the coke oven having the above configuration, generally, the operation is performed by the operation of a worker who is in a cab of an electric vehicle towing the fire extinguishing vehicle. After the raw coal is charged and fired sequentially into the furnace chambers in the coke oven configuration by the charging vehicle, an extruder, a guide vehicle, and a fire extinguishing vehicle are placed in the corresponding furnace room where the kiln is discharged. Each extruder extrudes red hot coke as it is fired by the extruder, and the fire extinguishing car moves in synchronization with the extrusion speed while opening and closing the fire extinguishing car. Red hot coke is loaded and received on the car with the door closed, and after loading is completed, the fire extinguishing vehicle is run toward the fire tower and stopped accurately at a predetermined position in the fire tower. Spray the loaded red-hot coke from the tank aquarium on the tower to extinguish the fire, and after draining it sufficiently, run the fire extinguishing truck toward Coke Wharf this time to make sure that And then open the door to open and extinguish the extinguished coke on the predetermined wharf and discharge it, thus ending the kiln receiving work in this way. The required kiln dispensing is continuously performed by repeating the process sequentially for each room.

[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. Even if the track surface itself takes up itself, the total weight of the fire extinguishing vehicle and the electric vehicle towing the fire extinguishing vehicle is considerably large (for example, the own weight of the fire extinguishing vehicle is 55 t, the own weight of the electric vehicle is 35 t, (Weight of about 90 tons), the load weight on the track surface is large, and the relative positional relationship of the track surface to the furnace body, fire tower, coke wharf, etc. tends to fluctuate. It is not always possible to achieve effective automatic control because it cannot be made on a surface, and in order to withstand such an excessive load weight, a sufficient concrete foundation structure must be provided to improve the track floor strength. There must order, it was those that require a lot of foundation work cost.

On the other hand, in the coke oven equipment operated as described above, it is necessary to load the raw coal into the furnace chamber, unload the coke itself to be fired and extinguished, and extinguish the fire. It has the disadvantage that the operating atmosphere is extremely bad because of the tendency of dust scattering and soaring, and the electric vehicle on the trolley wire and the fire extinguishing vehicle in such a bad environment. Various undesired problems also occur in each power supply to the air compressor and the like.

The present invention has been made in order to solve such a conventional problem, and an object of the present invention is to improve a driving system for running a fire extinguishing vehicle in a coke oven facility by using a trolley. In a state in which traction is avoided in an electric vehicle which receives power from the line, in other words, in a state where a trolley line is not used, a compressed air generation source mounted on the fire extinguishing vehicle can be operated effectively. An object of the present invention is to provide a compressed air generator for a coke oven fire extinguishing car of this type.

[Means for solving the problem]

In order to achieve the above object, the compressed air generator of the coke oven fire extinguishing vehicle according to the present invention is driven by a winch device via a wire rope for driving the fire extinguishing vehicle. In addition, as the fire extinguishing vehicle travels by pulling a wire rope, the air compressor is driven by using the rotational force of the traveling wheels to obtain required compressed air.

That is, the present invention is operated in conjunction with the extruder,
It has a fire extinguishing car that travels on the track by wire rope pulling means, and after the extruder receives fired coke extruded from the designated furnace chamber of the coke oven on the fire extinguishing car, the fire extinguishing car travels inside the fire extinguishing tower In a coke oven fire extinguishing vehicle that moves to perform coke extinguishing and that travels to a designated wharf location of coke wharf and discharges the processed coke, power transmission between the extinguishing vehicle and running wheels An air compressor connected and connected via a device, and a compressed air tank for storing compressed air obtained by the air compressor are mounted on each of the air compressors. Characterized in that coke is transmitted to an air compressor through a power transmission device, and the air compressor is driven to rotate to generate compressed air. A fire-fighting vehicle of the compressed air generator.

[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 loaded load is applied, so that the load weight on the track surface can be remarkably reduced, and the conventional trolley wire for supplying electricity to the electric car can be eliminated. Since the air compressor is connected and connected via a power transmission device between the fire extinguisher and the driving force of the traveling wheels, the air compressor can be driven. Since the compressor is driven, compressed air at a required pressure can always be generated effectively.
