Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a compressed air generation device for a coke oven fire extinguishing vehicle, and more particularly, to a compressed air generating device for a coke oven fire extinguishing vehicle that is driven by a wire rope traction means. It is related to the device.

[Conventional technology]

Conventionally, this type of coke oven equipment usually includes a coke oven that burns raw coal in individual furnace chambers installed in parallel, a charging vehicle that charges raw coal into each furnace chamber, and an extruder that extrudes calcined red-hot coke from each furnace chamber; a fire extinguisher that loads and receives the red-hot coke extruded by the extruder through the intervention of a guide car;
Each station has a fire tower that extinguishes the red-hot coke loaded on the fire extinguisher by spraying water, and a coke wharf that receives the coke scraped from the fire extinguisher. Tracks are laid corresponding to each of these parts. A trolley line is installed above the trolley line, and a fire extinguishing truck is towed on the track by an electric car that receives power from the trolley line and is operated. The engine is equipped with an electric compressor, a compressed air tank, etc. as a compressed air source used to open and close the fire extinguisher, or to brake and stop the fire extinguisher itself.

The operation control of a fire extinguisher in a coke oven with the above configuration is generally performed by a worker in the driver's cab of an electric car pulling the fire extinguisher, and the operation procedure is as follows: In a coke oven configuration, raw coal is sequentially charged and fired into each furnace chamber using a charging car, and then an extruder, a guide car, and a fire extinguisher are installed at the corresponding furnace chamber position where the furnace is discharged from the kiln. The fire extinguishing trucks are parked with accurate alignment, and when the extruder extrudes the calcined red hot coke, the extinguishing truck is opened and closed while moving in synchronization with the extrusion speed. Red-hot coke is loaded on top of the car with the door closed, and the carcasses are disposed of. After loading, the fire extinguishing truck is driven toward the fire tower, stopped precisely at a predetermined position inside the fire tower, and In this state, the loaded red-hot coke is extinguished by being sprayed with water from the tank on top of the tower, and after the water has been thoroughly drained, a fire extinguisher is driven towards the coke wharf and the fire extinguisher is driven to the designated wharf location. After that, the door is opened and the extinguished coke is unloaded onto the specified wharf point to be disposed of. In this way, the half-cycle of the kiln receiver is completed, and from now on, this This process is repeated in sequence for each furnace chamber to continuously carry out the required unloading of the kiln.

[Problems to be Solved by the Invention] By the way, regarding the operation of the above-mentioned coke oven fire extinguishing vehicle, the interaction with other working machines such as guide vehicles and extruders is extremely important, and for this purpose, Normally, it is necessary for workers in each department to communicate with each other using communication means such as wired or wireless telephones, and to proceed with work while checking the working status and working position of each working machine. be.

However, in such artificial and manual operation operations based on mutual communication between workers, false alarms are likely to occur due to misunderstandings, and it is not always possible to accurately grasp the work status, work position, etc. There is a problem.

Therefore, in the past, these extruder guide wheels,
There have also been proposals for automatically controlling the operating operations of various working machines such as fire engines and fire engines. In addition, since the total weight of the electric cars towing the fire engine is quite large (for example, the weight of the fire engine is 55 tons, the weight of the electric car is 35 tons, and the total weight is about 90 tons), the load on the track surface is large. (The relative positional relationship of the raceway surface with respect to the reactor body, fire tower, coke wharf, etc. is likely to fluctuate, and this raceway surface itself cannot be used as a reference surface for operation.) Therefore, effective automatic control is not always possible. In order to withstand such an excessive load, it is necessary to increase the strength of the track method by constructing a sufficient concrete foundation structure, which requires a large amount of foundation construction costs. there were.

On the other hand, in the coke oven equipment operated as described above, there are inevitably It is easy to cause dust to scatter and fly up, and has the disadvantage of an extremely poor operating atmosphere. The power supply to electric compressors and the like also causes various undesirable problems.

This invention was made to solve these conventional problems, and its purpose is to improve the operating method for running a fire extinguisher in a coke oven facility, and to improve the trolley system. The compressed air generation source mounted on the fire extinguishing vehicle can be effectively operated in a state in which towing by an electric vehicle receiving power from the line is avoided, in other words, in a state in which the trolley wire is not used. It is an object of the present invention to provide a compressed air generating device for a coke oven fire extinguishing vehicle of this type.

[Means to solve the problem]

In order to achieve the above object, the compressed air generating device for a coke oven fire extinguishing vehicle according to the present invention is provided with a traction system using a winch device via a wire rope to drive the fire extinguishing vehicle. , when the fire extinguisher is stopped under the fire tower to extinguish red-hot coke trapped on top of the vehicle, in other words, the time the fire extinguisher is stopped is relatively long (during work that can be done, In response to a stoppage, power is supplied to the installed electric compressor in a concentrated manner, making it possible to obtain the required compressed air.

That is, the present invention has a fire extinguishing vehicle equipped with a compressed air generator including an electric compressor, and is operated in conjunction with an extruder and runs on a track by means of wire rope pulling means, and the extruder drives a coke oven. The calcined coke pushed out from the designated furnace room is deposited on a fire extinguisher, and the fire extinguisher is moved into the fire extinguishing tower to extinguish the coke, and then moved to the designated wharf location of the coke wharf for disposal. In the coke oven fire extinguishing vehicle, the fire extinguishing tower is provided at a predetermined position with fixed position detection means for detecting entry of the fire extinguishing vehicle into a fixed position and outputting a detection signal, and a power supply means that is energized and controlled by the detection signal. , In addition, the fire extinguishing truck includes:
A power receiving means is provided that receives power by contacting the power feeding means as it enters a fixed position within the fire tower, and stops the fire extinguishing vehicle at a fixed position within the fire tower according to the detection signal, and receives the power. This is a compressed air generation device for a coke oven fire extinguishing vehicle, characterized in that the electric compressor is driven by electric power supplied through the means to generate compressed air.

[Function] Therefore, in the device of this invention, a traction method using a winch device via a wire rope is adopted for the running operation of the fire extinguishing truck that runs on a predetermined track surface.
Only the empty weight or the live load of the fire extinguisher is applied to the track surface, which significantly reduces the load weight on the track surface, and the conventional trolley wire for energizing electric cars can be abolished. Moreover, a fixed position detection means for detecting the entry of a fire extinguisher into a fixed position and a power supply means controlled by the detection signal are provided at a predetermined position of the fire extinguishing tower, and the fire extinguisher is provided with Since the device is equipped with a power receiving means that receives power from the power supply means as it approaches a fixed position, the electric compressor on the fire extinguisher can be operated by the supplied electric power when the fire engine is stopped at a fixed position in the fire tower. It can be driven to effectively generate compressed air.
