[Conventional technology]

Conventionally, as the one for loading the scorching coke discharged from the coke oven on the bucket car through the guide car, for example,
There is something like the one shown in the figure. The scorching coke coming out of the coke oven 1 is extruded by an extruder 3 running on a rail 2 parallel to the coke oven 1, and the scorching coke is
It is moved to a guide wheel 5 running on a rail 4 parallel to the coke oven 1 on the opposite side of the extruder 3, and is further loaded on a bucket truck 7 running on a rail 6 parallel to the coke oven. To this end, the extruder 3 and the extrusion port of the coke oven 1,
It is necessary that the stop position of the guide vehicle 5 and the stop position of the bucket vehicle 7 are at predetermined positions. Therefore, the worker visually confirmed the predetermined position, but recently, for example, the guide car 5 is provided with the light emitter 8 and the bucket car 7 is provided with the light receiver 9.
When the light receiver 9 of the bucket wheel 7 receives the light of the light emitter 8 of the guide wheel 5, it is determined that the positions of the guide wheel 5 and the bucket wheel 7 are coincident with each other, and the pushing operation of the caustic coke is started. That was done (Actually 52-78449
(See the official gazette).

[Problems to be solved by the device]

By the way, in such a conventional position confirmation device for a coke oven working machine, a lot of skilled manpower is required when performing the position adjustment manually, and in the device for detecting the position by light as described above, However, if the relative positions of the guide vehicle 5 and the bucket vehicle 7 coincide with each other, there is a problem that the pushing operation is started because a signal indicating that the alignment is completed is output even when the two are traveling.

The present invention has been made in view of such a conventional problem, and the extruder 3, the extrusion port of the coke oven 1, the stop position of the guide car 5 and the stop position of the bucket car 7 are all at predetermined positions. It is an object of the present invention to obtain a position confirmation device for a coke oven working machine in which extrusion of the caustic coke is started only when

[Means for Solving the Problems]

As a means for solving the above problems, the present invention uses a coke extruder that runs coke in a coke oven on a rail parallel to the coke oven, sandwiching the coke extruder and the coke oven. In a device for loading on a bucket truck that also travels on a rail that is parallel to the coke oven via a guide vehicle that travels on a rail that is parallel to the rail, the guide vehicle is provided, and the guide rail is a coke extruder. To reach a predetermined position which is arranged to push out, and when the grid of the guide wheel moves toward the coke oven and reaches the predetermined position, the reaction object for position detection is moved to a specific position in the guide wheel. And a reaction object moving device for moving the bucket vehicle to detect the presence and position of the position-detecting reaction object to stop the bucket vehicle. Next, the operation of the present invention will be described. In the reaction object moving device provided in the guide car, the guide car is arranged so that the coke extruder pushes out the coke. When a certain position is reached and the grid of the guide car moves toward the coke oven and reaches the predetermined position, the reaction object for detecting the position of the bucket car is moved to a specific position inside the guide car. .
When the position detection device provided in the bucket vehicle detects the presence and position of the position detecting reaction object, it is detected that the bucket vehicle is at the position to stop. Therefore, when the position detecting device is operated, the confirmation signal is sent from the position detecting device to the extruder, whereby the coke pushing operation is started and the work is always performed at the correct position.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, a coke oven
The burning coke coming out of 11, as shown in Fig. 2,
It is extruded by a coke extruder 12, and is injected into a fire extinguishing bucket provided on the opposite side of the extruder 12 with respect to the coke oven 11. To describe the configuration of the fire extinguishing bucket portion on the opposite side of the extruder 12, a rail 14 is laid parallel to the coke oven 11 extending in the longitudinal direction, and a guide wheel 15 travels on the rail 14. Then, the caulking coke is injected into the bucket car 17 via the guide car 15, but like the rail 14, there is a rail 16 parallel to the coke oven 11, on which the bucket car 17 runs. The guide wheel 15 and the bucket wheel 17 are aligned with each other. Guide car 15
Inside, the guide wheel 15 reaches the position of the extrusion kiln 18 in which the coke extruder 12 is arranged to push out the coke, and the lattice 19 of the guide wheel 15 moves toward the coke oven to reach the predetermined position. Then, there is an air cylinder 21 as a reaction object moving device that moves the reflection plate 20 as a position detection reaction object provided in the guide wheel 15 to a specific position in the guide wheel 15. On the other hand, in the bucket car 17, the guide car 15
There is an ultrasonic transmission / reception device 23 as a position detection device that detects the presence and position of the reflection plate 20 inside. Ultrasonic transceiver
23 includes a controller 24, an ultrasonic transmitter 25, an ultrasonic sensor 26, and a control device (not shown) that transmits a confirmation signal to the push-out vehicle 12 after confirming the position, which stops the bucket vehicle 17. This is for detecting the position where the operation is performed.

When the coke is charged into the coke oven 11 by a coke charging vehicle (not shown), and when the coke is burned, the extruding unit 12 moved to a predetermined position causes the burning coke to be extruded. Therefore, when a coke push command is issued from the pre-programmed central controller, the coke is transferred to the bucket vehicle 17, so the bucket vehicle 17 starts moving and the extruder 12 is arranged by the command of the central controller. It is aligned and stopped at the extrusion kiln 18 that is currently installed. The guide wheel 15 also starts moving to the position of the coke pushing kiln 18 and stops when it reaches a predetermined position.
Advancing the lattice 19 in the direction of the coke oven. When the lattice 19 reaches the predetermined position of the coke oven, the air cylinder 21 in the guide wheel 15 is activated to lower the reflection plate 20 to the predetermined position as shown in FIG. The bucket car 17 has an ultrasonic transceiver
There is 23, from the ultrasonic transmitter 25 in this, when the bucket car 17 is stopped at all times, it is adapted to emit ultrasonic waves, when the reflector 20 descends and approaches a predetermined position. The ultrasonic waves are reflected by the reflection plate 20 and received by the ultrasonic sensor 26.

In this way, the positions of the bucket wheel 17 and the guide wheel 15 are confirmed.At that position, the coke extruder 12 extrudes the scorching coke, so that the coke extrusion can be injected into the bucket wheel 17 via the guide wheel 15. Machine 12, guide car
The 15 and the bucket car 17 are arranged at appropriate positions. With this confirmation signal, the turning bucket of the bucket vehicle 17 starts turning, and transmits a positioning completion signal to the central control position. The central control unit sends a signal of alignment completion to the coke extruder 12 waiting for extrusion preparation, adjusts the extrusion interlock condition, and starts extrusion. When the pushing out of the coke is completed, the lattice 19 of the guide wheel 15 automatically moves backward, the air cylinder 21 also rises, and the reflector 20 rises.
Return to the initial state and wait.

As described above, the alignment of the guide car 15 and the bucket car 17 is
According to a command from the central control unit, the bucket wheel 17 first stops at the extrusion kiln 18 in which the extruder 12 is arranged, then the guide wheel 15 reaches a predetermined position, and the reflector plate 20 descends according to the condition and aligns. Therefore, there is no signal that the alignment is completed while the guide vehicle 15 is moving, and the safety of work is secured. As a result, safe work is always performed, and the work can be automatically performed even if the worker does not monitor it.

Although the reflecting plate 20 is used as the position detecting reaction object of the guide wheel in the above-described embodiment, other means such as a reflecting mirror or a magnetic material may be used as long as it can be used for position detecting. Further, although the air cylinder 21 is used as the reaction object moving device, a moving device using an electric motor, a hydraulic device or any other moving device may be used, and it is decided that the reflecting plate 20 is also lowered from the above. Good. Further, although the ultrasonic transmitting / receiving device 23 is used as the position detecting device, an appropriate device such as a device using light, a magnetic proximity sensor, or the like can be selected and used depending on the case.
