[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling device for fine adjustment of a fixed position of a coke oven moving machine.

[0002]

2. Description of the Related Art A traveling device for finely adjusting a fixed position of a coke oven moving machine of this type has been implemented as follows according to a conventionally known configuration.

[0003] In order to stop the moving machine at the target position of the coke oven, it is necessary to detect the target position. The moving machine is provided with an axle rotation speed detector and a distance measuring wheel with a touch roller to the rail. In addition, an optical sensor for detecting the relative position between the moving machine and the coke oven was provided. The detected signal is sent to a drive motor provided on the drive-side wheel of the mobile machine to stop the mobile machine at a target position.

However, the actual stop position has deviated from the target stop position due to various causes. Fine adjustments have additionally been made to correct this shift by inching the drive motor or by operating a hydraulic cylinder.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to create a means for correcting a deviation between a target stop position and an actual stop position of a mobile machine with respect to a coke oven.

An object of the present invention is to provide a configuration described in claim 1 of a utility model registration, that is, a fine adjustment drive device is attached to a longitudinally moving wheel of a mobile machine, and the mobile machine is provided with a fine adjustment drive device. The problem is solved by providing a relative position detector between the coke oven and the moving machine and a fixing device for fixing the moving machine to the rail.

The present invention is characterized in that the role of traveling of the mobile machine 1 over a large distance and the traveling of fine adjustment are separated into the drive motor 8 and the fine adjustment drive device 3. (Operation) The moving machine is provided with a fine adjustment drive device on the driven wheel of the moving machine, a relative position detector between the coke oven and the moving machine, and a fixing device for fixing the moving machine on the rail. Is accurately moved to the target position and fixed at that position.

【Example】

(Configuration) According to FIGS. 1 to 5, the moving machine 1 traveling on a rail 5 installed on the floor in front of a furnace (not shown) has a driving side on which driving wheels 7 are largely driven. Motor 8 for driving the moving machine 1 to the driven wheel 2 on its driven side
And a fine adjustment driving device 3 for small-width driving. As a moving machine around the coke oven, there are a guide car, a coal car and an extruder.

On the driving side of the mobile machine 1, a distance measuring wheel 9 for measuring a large moving distance of the mobile machine 1 is provided. A position detector 4 for detecting a position detection mark provided in a furnace (not shown) is provided on the driven side of the mobile machine 1.
Is provided.

A door lifter 12 for opening and closing a furnace door 10 (not shown) is attached to a central frame of the mobile machine 1, and the door 1 is opened when the mobile machine 1 stops in front of the furnace.
0 is attached and detached. The door lifter 12 also rotates the door 10 about the door center 11 to clean the door 10. The guide 13 is also attached to the center frame of the mobile machine 1, and coke is carried out by moving the guide 13 forward and backward at the guide center 14.

The weight of the mobile machine 1 is about 180 tons,
The output of the drive motor 8 of the mobile machine is 22 KW2 units.
The traveling speed of the mobile machine by the drive motor 8 is about 5 to 10 m / min at low speed.

As the fine adjustment driving device 3 of the mobile machine 1, there are two electric motors having an output of 1.5 kW. The electric motor 3 arranged on the driven-side support plate is operatively connected to the shaft of the driven-side wheel 2 via, for example, a screw gear or a reduction gear 16 composed of a worm and a worm wheel. When the hydraulic cylinder 15 is used instead of the electric motor 3, the piston rod of the hydraulic cylinder 15 disposed on the driven-side support plate is similarly connected to a lever 17 fixed to the shaft of the driven wheel 2 via a joint. Are operatively connected. Thereby, the driven wheel 2 is rotated to one or the other (in the forward or backward direction of the mobile machine 1) by the operation of the electric motor 3 or the hydraulic cylinder 15.
The speed at which the mobile machine 1 travels by the fine adjustment driving device 3 is about 0.5 m / min. The mobile machine 1 is provided with a fixing device 6 for fixing the position of the mobile machine on the rail 5. (Operation) The position detector 4 is a proximity sensor using a magnetic field. As another method, an optical sensor may be used. The signal from the position detector 4 is sent to the drive motor 8 to stop the moving machine 1. The actual stop position deviates from the target stop position by 0 to ± 40 mm. This shift is caused by a change in running resistance, a change in friction coefficient due to dust on the rail, and the like. The target stop position can also be approached by the distance measuring drive wheel 9 for detecting the position from the traveling distance of the rail 5.
Cannot be detected up to the exact relative position of.

When the moving machine 1 is a guide car when traveling between kilns, the distance L from the center 11 of the door 10 to the center 14 of the guide 13 when the machine 1 travels between kilns.
When traveling between the guide wheels, the guide wheel 1 is moved by the drive motor 8 provided on the drive side wheels 7. The target stop position of the mobile machine 1 is detected by the distance measuring wheel 9. The detected stop signal is transmitted to the drive motor 8, but since the heavy-weight moving machine 1 is stopped by the large-size drive motor 8, even a minute mechanical movement cannot be controlled. As a result, the actual stop position deviates from the target stop position. This displacement is detected by the position detector 4. This detection method may be based on a mechanical measure cylinder in addition to the proximity sensor using a magnetic field. This difference is at most 0 to ± 40 mm as described above. Next, the difference signal is sent to a small-sized fine-adjustment moving device 3 provided on the driven wheel 2, which is started to move the moving machine 1 to about 0.5 m / min, and thus to about 8 m / min.
It is moved to a target position at a speed of mm / s. The travel time is a few seconds. Since the fine-adjustment moving machine 3 is dedicated to fine-adjustment, it does not require the action of the large and fast moving motor 8 of the moving machine 1. Therefore, the driven machine 2 is provided with the small-sized fine adjustment drive device 3 and the driven wheel 2 provided with a gear having a large reduction ratio, so that the moving machine 1 can move smoothly and minutely over a small distance and accurately stop at the target position.

When the moving machine 1 stops, the fixing device 6 attached to the moving machine 1 operates to fix the moving machine 1 to the rail 5. When the fixation is completed, the work of the coke oven by the attachment / detachment of the door 10 by the door lifter 12 or the forward / backward movement of the guide 13 is performed.

[0015]

[Effect of the Invention] The traveling control of the mobile machine is facilitated by the separation of the functions of the large drive and the fine adjustment drive.

A deceleration mechanism is provided by separating functions of driving and fine adjustment.
The control mechanism has become very simple. Accordingly, the mobile machine 1 can be accurately and easily stopped at the target position by the fine adjustment traveling. Being able to easily stop at the target position does not require re-running, and does not waste working time.

The amount of movement by the fine adjustment driving device 3 is at most ± 4.
Since the distance is 0 mm, the driving power can be extremely small. In the case where an existing mobile machine is modified for automation purposes, the drive wheels may be left as they are and only the periphery of the driven wheels may be modified. There are few remodeling places,
Since the remodeling is simple, the home position fine-tuning traveling can be easily realized.
