Description

Operating device of trolley for moving slag port

The present invention relates to a device for automatically operating a bogie that moves the slag port containing the slag generated during the converter drilling process, more specifically, the slag port movement bogie automatically and semi-automatically using a monitor installed in the central control room. It relates to a device to operate.

In general, during the process of refining molten iron to molten steel, slag, which is an industrial waste, is generated as a by-product, and a slag port moving cart is used to move the slag port containing such slag.

Conventionally, the operation of the slag port moving trolley was performed at the work site, and the slag port moving trolley 4 was moved by operating the operation lever 12 provided at the working site as shown in FIG.

That is, by operating the operation lever 12, the central processor 14 operates the motor of the slag port moving cart 4 and the winder cable operating motor through the bogie motor controller 13, thereby allowing the slag port moving bogie 4 to operate. To make the transition between the furnace bottom and the slag yard.

However, the prior art as described above was inconvenient that the operator must be in the field to operate and operate the slag port moving trolley 4, the operation lever 12 of the slag port moving trolley 4 installed on the site Slag port due to the characteristics of converter work that requires the operator to operate the operation lever 12 for a long time during which the slag port moving trolley 4 moves, and withdraw the slag port moving trolley 4 in a timely manner. By separately designating and managing the workers driving the mobile truck 4, inefficient operation and irrational arrangement of personnel were inevitable.

In case of rain, the slag port moving trolley (4) located in the slag yard must be pulled into the furnace (1) furnace in a short time so that the rainwater is not contained in the slag port (5) to prevent an accident such as an explosion. As a result, more and more fixed arrangements of workers were required, there was a potential for risk of safety accidents as well as accumulation of workers' fatigue.

The present invention is to provide a driving device of the slag port moving cart that can operate the slag port moving trolley in the central control room and to monitor the overall movement of the slag port moving trolley in the central operation room. The purpose.

A slag port detection switch installed on an upper surface of the slag port moving cart; A monitoring camera operated by a signal of the limit switch and installed at one side of the lower part of the converter furnace and the slag yard; A surveillance monitor operated by a monitor controller connected to the surveillance camera and installed in a central operation room; It is connected to the operating lever and the central processor to provide a control device for the slag port moving bogie, characterized in that consisting of a control panel installed in the central operation room.

In addition, the operating panel is further provided with a manual lever for moving the balance.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

2 is an overall schematic view of the present device.

According to the present invention, a striker 6 is attached to one side, and a slag port detection switch 15 is installed at the center of the slag port moving trolley 4 on which a driving motor operated by the motor controller 13 is mounted. do.

In addition, the lower part of the furnace furnace and the slag yard is installed on one side and the monitoring camera (21, 22) operating in accordance with the signal of the limit switch (8, 18) interlocked with the striker (6) of the trolley (4) And a monitor monitor 20 installed at one side of the slag yard and operated by a monitor controller 23 connected to the surveillance cameras 21 and 22 in the central operation room 17.

On the other hand, the central processor 14 to collectively control the slag port detection switch 15, the motor controller 13, the limit switch (8, 18) and the monitor controller 23 and the operating lever installed in the conventional field Is connected to the (12), the operation panel 11 for controlling this is installed in the central operation room 17, the operation panel 11 is a manual lever (10) for manually operating the cart (4) ) Is installed.

Hereinafter, the operation of the present invention will be described.

Looking at the operation of the device of the present invention having the configuration as described above, if the slag port 5 is placed on the upper portion of the trolley 4 to withdraw the slag from the converter 1, the motor by the slag port detection switch 15 When the controller 13 drives the drive motor of the trolley 4 to move the trolley 4 toward the lower furnace front, and the striker 6 on one side of the trolley 4 is detected by the limit switch 8 of the lower furnace front. The movement of the trolley 4 is stopped, and at the same time, the surveillance camera 22 is operated to show the state of the trolley 4 on the surveillance monitor 20 of the central operation room 17.

Then, when the slag discharge from the converter (1) is completed, when the operator pushes the automatic bogie take-off switch on the operation panel 11, the bogie 4 moves to the slag yard, and this process is carried out to the surveillance cameras 21 and 22. By appearing on the monitor 20 by this, the operator can easily monitor the movement of the cart 4.

When the striker 6 of the trolley 4 moved in this way comes into contact with the limit switch 18 provided on one side of the slag yard, the trolley 4 stops, and the slag port 5 is lifted by the overhead crane from the top. When slag is excavated and the slag port 5 is placed on the trolley 4 again, the trolley 4 is moved back to the converter bottom by the slag port detection switch 15.

On the other hand, when the trolley 4 is operated without using the automatic withdrawal switch, the trolley 4 may be moved by using the manual lever 10.

According to the present invention as described above, the operation of the slag port moving trolley for carrying the slag port can be reduced by the one-touch method, thereby reducing the work load of the worker and of course, the monitoring camera according to the present invention. Ease of monitoring can maintain stability throughout the converter blowdown operation.
