Description

Automatic opening and closing device of dummy bar winch hole

The present invention is a dummy bar winch in the dummy bar winch system of the continuous casting machine in which the dummy bar winch hook has a hole formed in the column to move up and down. The present invention relates to an automatic opening and closing device of a hole, in particular, to prevent a worker from falling into the dummy bar winch hole due to carelessness during work and to prevent the radiant heat of the cast steel from rising to the dummy bar winch hole, thereby forming a safe working condition for the worker. .

In general, the dummy bar winch system of the continuous casting machine is in a state where the dummy bar winch hole is opened, and if the user loses his foot or loses his balance due to a worker's mistake, he falls to the dummy bar winch hole and causes a fatal injury. Occasionally, there was a risk of safety at all times. In addition, under the dummy bar winch hole, high temperature slab radiant heat went up to the dummy bar winch hole through an open dummy bar winch hole while a hot cast steel during casting was passed. As a result, the work condition of the worker may be impaired, and in particular, in summer, the temperature of the work place and the rate of cast iron are increased, and thus the work is avoided due to the difficulty of work by the room temperature of the work place. It led to inefficiency of the work.

The present invention is designed to solve this problem in consideration of the above-mentioned problems, and its purpose is to ensure the safety of the worker and to improve the working environment by blocking the rise of radiant heat generated from the cast steel, which is a dummy bar winch. Safety cover rails are installed on the left and right sides of the panel where the holes are formed, and the driving wheels are installed on the front and rear sides, respectively, and the safety locker with nimit switch is mounted on the front center and the rear of the panel. The safety cover operating cylinder and the limit switch on one side and the valve stand on the other side, and the dummy bar winch is connected to the frame is installed by installing a control box having a warning light.

The present invention provides a dummy bar winch 13 having a hook 14 and a hoist 15 having hooks 16 connected to each of the frames 17 and 17 ', and a dummy bar winch hole 7 and The dummy bar car rail 9 is provided, and in the usual case where the handrail 10 is provided around the dummy bar winch hole 7, the dummy bar winch hole 7 is formed. Safety cover rails (4) and (4 ') are installed on both left and right sides, and drive wheels (2) and (2') are installed on both sides of the front and rear, respectively, and the limit switch (3) is attached to the front center. The safety cover 1 is seated, while the rear cover of the panel 8 is provided with a safety cover operating cylinder 6 and a limit switch 3 'on one side and a valve stand 5 on the other side. 13 is connected to the frame 17 is provided by installing a control box 12 having a warning light (11).

Reference numeral 18 is an operation box.

Referring to the effect of the present invention configured as described above are as follows.

In the present invention, the dummy bar 20 mounted on the dummy barcar 21 waits while the dummy bar winch 13 is positioned at the rising end point, and molds the dummy bar car 21 at the time of preparing for the casting operation. The dummy bar 20 is inserted into the installation by moving toward the head, and the head part of the dummy bar 20 is positioned in the mold 22.

When the insertion of the dummy bar 20 is completed as described above, the dummy bar car 21 moves to the standby position and is ready for casting. In this case, the dummy bar winch 13 is lowered to move the dummy bar 20. You stop at a position where you can walk up.

In addition, when the ladle 23 of the molten steel to start the casting operation arrives, the middle of the ladle 23 and the mold 22, the tundish 24, which is an intermediate container, is moved by the tundish car 21, Molten steel is injected into the tundish 24 and casting is performed by continuously injecting molten steel into the mold 22 again from the tundish 24.

On the other hand, the head portion of the dummy bar 20 is connected to the initial molten steel injected into the mold 22, and when the draw bar 26 draws the dummy bar 20, the cast steel begins to solidify in the mold 22 As the casting is continuously made, the dummy bar 20 is drawn out of the facility. At this time, the dummy bar 20 rises up to the main column by the dummy bar winch 13 and the dummy bar head separating device 27 The dummy bar 20 and the slab 25 are separated from each other by the mold 22 and the dummy bar 20 is lifted up to the columnar phase by the dummy bar winch 13 and then stopped.

In addition, when the dummy bar 20 rises on the column and stops, the dummy bar 20 is transferred to the dummy bar car 21, and the dummy bar winch 13 transfers the dummy bar 20 to the dummy bar car 21. After that, it rises and waits until it reaches the end point of the ascending position.

As described above, the dummy bar car 21 waits at the standby position, and then adjusts the head width of the dummy bar 20 according to the casting width for the next casting operation, and then replaces the head portion using the head replacement hoist 15.

In addition, when the casting operation is completed, the dummy bar 20 is inserted into the equipment again, so that the circulation of the dummy bar 20 is performed. The operation of the safety cover 1 of the present invention is performed in the operation box 18. When the automatic operation is selected, the safety cover 1 is opened and closed according to the position of the dummy bar winch 13, and the closing operation is a dummy bar winch 13 with a dummy bar 20 coming out of the facility and coming up with a dummy bar 20 ), After taking over the dummy bar car 21 and rising to the rising end point, the timer is operated by receiving a signal of the dummy bar car 21 after the dummy bar 20 is completely loaded on the dummy bar car 21. The driving wheels 2, 2 'installed at the front and rear of the safety cover 1 are driven along the safety cover rails 4, 4' by the signal, and the safety cover 1 is a dummy bar winch hole ( 7) closes.

In addition, the present invention is the safety cover (1) is in a closed state until the dummy bar winch (13) is moved and the safety cover (1) immediately after the dummy bar winch (13) starts to descend to the rising end point Will be opened. At this time, if the dummy bar winch 13 starts to descend and the lamp for opening the safety cover 1 does not turn on even after a certain time, the dummy bar winch 13 is automatically opened by the limit switch 3 at the lower end point. do.

The present invention as described above can be carried out by the operation of the limit switch to automatically open and close the dummy bar winch hole by the operation of the limit switch to prevent the risk of falling of the operator and to prevent the radiant heat of the slab to rise to the dummy bar winch hole By preventing the temperature rise in the workplace there is an effect that can ensure the safety as well as the efficiency of the work.
