Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an automatic coke oven fire extinguishing vehicle for driving an unmanned dry fire extinguishing vehicle and a manned wet fire extinguishing vehicle in common on a coke oven fire extinguishing truck travel path. Regarding an operation control method.

Conventional technology Coke oven kiln unloading work involves repeated operations by sequentially operating the extruder, coal loading car, coke guide car, and fire extinguishing truck in the kiln unloading furnace chamber determined based on the work plan. It is done. Therefore, each mobile machine can proceed with its work while maintaining communication with each other and confirming each other's work and position.

Conventionally, communication between these mobile machines has been confirmed directly with the naked eye, by telephone, or by radio. but,
With these methods, mutual position confirmation is not sufficient;
In particular, there was no guarantee of safe operation due to contact with fellow aircraft traveling on the same trajectory.

Therefore, many automatic operation controls for coke oven fire extinguishing trucks have been proposed, and automatic operation controls for various moving machines surrounding coke ovens, including extruders, coal loading trucks, coke guide trucks, etc., have been proposed.

The automatic operation control method for a coke oven fire extinguisher is to install a guided radio line along the entire length of the fire extinguisher's driving route, continuously detect the position of the extinguisher, and send the signal to the fire extinguisher's control device on the ground. There is a method (Japanese Patent Publication No. 63-24633) of instructing a fire extinguisher to move, stop, and load and unload coke in sequence according to the work process based on each piece of information.

As with the automatic operation control method for the fire extinguisher mentioned above, the automatic control method for mobile coke oven machinery is to continuously detect the position of the mobile machine by installing a guided radio line along the entire driving route of the mobile machine, and to continuously detect the position of the mobile machine while working. There is a method (Japanese Unexamined Patent Publication No. 187789/1989) for transmitting information such as information and working kiln information.

In addition, as a device to prevent collisions between moving machines in a coke oven, when multiple moving machines share one track,
There is a device (Japanese Unexamined Patent Publication No. 172979/1983) that provides deceleration sections before and after the deceleration section and detects the presence or absence of other moving machines in the commonly used section to prevent collisions.

As is well known, there are two types of coke oven fire extinguishing trucks: wet type fire extinguishing trucks and dry type fire extinguishing trucks.

The driving pattern of the wet-type fire extinguishing truck is that it travels from a fixed stop position to the unloading kiln, and after arriving at the coke loading position, it loads the coke while traveling while driving toward the water tower, and then runs to the water tower. Extinguish the fire with water at the location. After extinguishing the fire, move to the front of the coke wharf, unload coke to the coke wharf, and drive to the fixed stop position.

In addition, the driving pattern of a dry fire extinguishing truck is that it travels from a fixed stop position to the unloading kiln, arrives at the coke loading position and receives the coke, then travels to the dry fire extinguishing tower, picks up the empty packets, and moves on to release the coke. The machine passes the loaded packet and travels to the next kiln, or travels to a fixed stopping position.

The former type of wet-type fire extinguishing truck requires the vehicle to be inched while checking the coke loading, unloading, and extinguishing conditions during wreckage work, fire extinguishing work, and coke unloading work, but water spray extinguishing uses a large amount of steam. There are problems such as dust generation and difficulty in detection for control purposes. On the other hand, the latter type of dry fire extinguishing truck is relatively easy to control automatically as it is handed over at a fixed location. Therefore, in the current fire extinguishing equipment of coke ovens, dry fire extinguishing trucks are fully unmanned and automated, while wet fire extinguishing trucks are operated by friends.

Problem to be Solved by the Invention In order to extinguish coke using the dry fire extinguishing equipment of a coke oven, in normal operation, there are multiple dry fire extinguishing trucks on one track laid between the coke oven and the dry fire extinguishing tower. , operating under automatic control.

However, when the dry fire extinguishing equipment is closed, and when the exhaust heat boiler is inspected,
Alternatively, in the event of equipment failure, the attached wet fire extinguishing equipment is used and a wet fire extinguishing truck is operated by a man.

Therefore, when the dry fire extinguishing equipment restarts, the dry fire extinguishing truck and the wet fire extinguishing truck share the same track, but sometimes the wet fire extinguishing truck is interposed between the dry fire extinguishing trucks and the operation is continued. It is done.

Therefore, it is necessary to prevent collisions between dry fire extinguishing trucks and wet fire extinguishing trucks at high speeds (10.8 km/hr). Also,
Because the location and operating status of manned wet fire extinguishing trucks are not input into the automatic control system, it is not possible to manage the schedule of dry fire extinguishing trucks, leading to problems such as delays in unloading kilns.

In order to solve the problem of the above-mentioned operation in which an unmanned dry fire extinguishing vehicle and a manned wet fire extinguishing vehicle coexist, the driving control of the wet fire extinguishing vehicle is controlled by an automatic control device on the ground together with the dry fire extinguishing vehicle through the intervention of the driver. In this paper, we propose an automatic operation control method for a coke oven fire extinguishing vehicle in which the wet fire extinguishing vehicle is manually operated to control the damping, extinguishing, and coke discharge operations.

Means for Solving the Problems In order to achieve the above object, the automatic operation control method for a coke oven fire extinguishing truck of the present invention continuously controls the position of the fire extinguishing truck by means of a guided radio line arranged along the entire length of the fire extinguishing truck's driving route. When a manned wet fire extinguishing vehicle is used in the driving route of an unmanned dry fire extinguishing vehicle whose operation is automatically controlled by an automatic operation control WJ device on the ground, a wet fire extinguishing vehicle is manually operated at the work point on the wet fire extinguishing vehicle. A manual operation panel for carrying out work, a movement requestor for automatically controlling the automatic operation IIJ1iIl device to move between work points, a travel controller, and a transmitter/receiver for transmitting information with the ground station. and transmit the signal from the movement requester to the automatic operation control device on the ground.
A traveling control device is installed to control the running of each fire extinguishing truck, including manned wet fire extinguishing trucks, and a transmitter/receiver is installed to transmit information and commands to and from the vehicle. This information is sent to the automatic driving control device on the ground using the manual operation panel on the vehicle, and based on this information, including information about the dry fire extinguishing vehicle, it is determined whether or not the wet fire extinguishing vehicle can run. The movement of the wet fire extinguishing truck between work points is controlled by commands from the automatic operation control device based on the results of calculations received from the movement request device manually operated by the driver. Ukketsu running,
Sprinkling water and discharging coke must be done manually using a manual control panel.

The operation status of the wet fire extinguisher, the position of the fire extinguisher, and the work schedule are sent as information to the automatic operation control device at the ground station.
By controlling the dry fire extinguishing vehicle in combination with information on its location and work schedule, it is possible to safely and automatically move manned wet fire extinguishing vehicles between work locations without competing with unmanned dry fire extinguishing vehicles. In addition, we will carry out carcasses at the work site,
Inching during water sprinkling and coke unloading is performed manually by the driver while visually observing the situation at the time, so each operation is performed accurately and quickly.

Since information such as the start and end of manually operated work is input to the automatic operation control device as information, movement between work points and work performed at each fixed position are organically combined, and fire extinguishing can be carried out efficiently.
