Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drive device for a coke oven fire extinguishing vehicle.

[Prior art 1] Conventionally, fire extinguishing trucks in coke ovens have been driven by electric cars that pull the fire extinguishing trucks, and their operation has generally been controlled by a worker riding on the electric car. The operating procedure for the electric car is to first accurately align the extruder, guide car, and fire extinguisher to the designated furnace chamber location for unloading the kiln in the coke oven configuration, and then park the car. state, red-hot coke is extruded by an extruder (
Then, while moving the fire extinguisher in synchronization with the extrusion speed, red-hot coke is loaded onto the fire extinguisher with its door closed, and the carcasses are buried. After loading, the fire extinguisher is moved to the fire extinguishing tower. After driving towards the fire tower and stopping accurately at a predetermined position inside the fire tower, fire extinguishing water was sprayed from the tank on top of the tower onto the loaded red-hot coke to extinguish it, and water was drained. The fire extinguishing truck is driven towards the coke wharf, stopped precisely in front of a predetermined wharf point, and then the extinguished coke is dumped onto the predetermined wharf point by opening the opening/closing door of the fire extinguisher and discharged. In this way, the current kiln receiver completes its work, and thereafter, this kiln receiver repeats the work sequentially for each furnace chamber where firing has been completed to 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 using an electric vehicle, the interaction with other working machines such as a guide vehicle and an extruder is extremely important. For this purpose, in normal cases, workers in their respective positions communicate with each other using communication means such as wired or wireless telephones, and check the working status and working position of each working machine. It is necessary to proceed with the work.

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 automatic control of the operation of each working machine, such as a fire extinguisher, based on a predetermined time schedule. Taking this into consideration, the total weight of the fire engine and the electric vehicle that tows the fire engine is quite large (for example, the fire engine's dead weight is 55 tons, the electric vehicle's dead weight is 35 tons, and the total weight is about 90 tons). Due to the heavy load on the raceway surface, the relative positional relationship of the raceway surface with respect to the reactor body, fire tower, coke wharf, etc. is likely to change (and the raceway surface itself cannot be used as a reference surface for operation, etc.). On the other hand, on the track surface, in order to withstand the load weight, sufficient concrete foundation structure must be provided to increase the strength of the track method. However, there were problems such as a large amount of cost required for this purpose.

This invention was made to solve these conventional problems, and its purpose is to improve the driving method for running a fire extinguishing truck in a coke oven, and to improve the effectiveness of the fire extinguishing truck. This enabled automatic control operations. It is an object of the present invention to provide a drive device for a coke oven fire extinguishing vehicle of this type.

[Means for Solving the Problems] In order to achieve the above object, a drive device for a coke oven fire extinguishing vehicle according to the present invention includes a drive device for a coke oven fire extinguishing vehicle that uses wire ropes to drive a fire extinguishing vehicle that runs on a predetermined track surface. A traction method using a winch device is adopted to reduce the load weight on the track surface of the fire extinguisher and prevent the position of the track surface from changing. This system ensures that the fire extinguisher's operation is controlled effectively and reliably.

That is, the present invention relates to each oven chamber of a coke oven.

It travels in a controlled manner in a reciprocating manner on a track laid between the fire tower and the coke wharf, and carries the calcined coke pushed out from the designated furnace chamber of the coke oven by an extruder onto the vehicle and moves it into the fire tower. A drive device for a coke oven fire extinguishing vehicle that extinguishes the coke that has been buried in the coke wharf, and moves to a designated wharf location of the coke wharf to dispose of the coke, the drive device comprising a drive and a driven vehicle disposed at both ends of the track. A wire rope wrapped endlessly between the drums is connected to the fire extinguisher, and the drive drum is rotated by a winch device, and the fire extinguisher is pulled by the wire rope and driven back and forth on the track. This is a drive device for a coke oven fire extinguishing vehicle, characterized in that it is capable of

In addition, the wire rope for towing the fire extinguishing vehicle includes a rope tensioning means for absorbing the amount of extension of the wire rope and slack at the time of start of travel to prevent slipping on the drive drum, and a rope tensioning means for preventing slipping on the drive drum. an emergency stop means for detecting abnormal extension or breakage of the fire extinguisher and stopping the fire extinguisher; This is a drive device for a coke oven fire extinguishing vehicle, characterized in that an out-of-travel range detecting means is provided, and the fire extinguishing vehicle can be brought to an emergency stop when detecting an out-of-travel range.

[For production]

Therefore, in the device of the present invention, in order to drive the fire extinguisher that runs on a predetermined track surface, a traction means using a winch device via a wire rope is adopted, and therefore, unlike the conventional device, electric vehicles Unlike in the case of driving by
Since only the live load is applied, the load weight on the raceway surface can be significantly reduced, positional fluctuations can be prevented, and the raceway surface itself can be used as a reference surface for driving operations. As a result, Not only does this enable effective automatic control by ensuring the relative position of the track surface and fire engine with respect to the reactor body, fire tower, coke wharf, etc., but it also reduces the equipment costs required to obtain the strength of the track method. It has the advantage of being able to be significantly reduced.

In addition, for the traction means using a winch device via the wire rope of the fire extinguisher, by providing a rope tensioning means, it is possible to absorb the amount of extension of the traction wire rope and the slack at the start of running, and to raise the tension on the drive drum. In order to prevent slippage, the drive amount by the winch device can accurately secure the running position on the track, and by providing an emergency stopping means, it is possible to prevent abnormal extension or breakage of the traction wire rope. In order to detect and make an emergency stop of the fire extinguisher, it is possible to prevent accidents in the event of an abnormality in traction using the wire rope.Furthermore, each end of the track is equipped with an out-of-travel area that detects when the fire extinguisher is out of the travel range. By providing the detection means, it is possible to prevent the fire extinguisher from running away when the fire extinguisher goes out of its travel range.
