JPS60184452A - Dummy bar guide device in continuous casting installation - Google Patents

Abstract

PURPOSE:To prevent failure of a driving mechanism part by forming the titled device into such mechanism in which a dummy bar guide is provided on the upper stream side of a hook for winding a dummy bar and the guide body is projected upward from below a roll top by the revolution of a cam. CONSTITUTION:When the tail part of a dummy bar 3 moves a detecting roller 6 after casting is started, a striker 23 contacts with the arm of a limit switch 25 and a hook 2 moves upward. The hook 2 engages with a pin 3A and a dummy bar 3 is wound up. A motor cylinder 14 is then actuated and a pinion 11 is revolved via a rack 12. The projecting part of a cam 7A is disengaged from a guide body 7B and since the guide body 7B and the roller 6 move both downward below the roll top, the billet does not collide against the same. Even if the dummy bar 3 hunts and collides against the body 7B, the body 7B is placed on the cam 7A and therefore no impact force is transmitted to the driving part. The failure thereof is thus prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tummy bar guide device in continuous casting equipment.

Conventional configuration and its problems In continuous casting equipment, the slab is pulled out along the slab conveyance path by pulling the tammy bar from the seventh lead, and then the tail portion of the tammy bar is placed at an appropriate position on the slab conveyance path. The hook for winding E is attached to the arranged tumbler, the connection between the head group of the tumbler bar and the slab is uncoupled, and the hook is raised to hoist the tumbler bar to the operating floor. In order to properly hold the pin of the Tammy Battail against the hook, a third bar guide is provided slightly on the E-stream side of the hook. Conventional glue bar guides are integrally connected to their drive mechanism, so if the meandering of the Tammy bar is larger than expected and it collides with the bar guide in Item 1, the drive mechanism part in Item F will also be damaged. The disadvantage is that it can cause a lot of damage. Furthermore, in the past, in order to make the tummy bar guide protrude from the bottom of the 0-ru top of the 0-ru that constitutes the slab conveyance path in the E direction, the tummy bar guide was swung. The disadvantage is that the structure becomes complicated, leading to increased costs.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a dummy bar guide device for continuous casting equipment that eliminates the drawbacks of the prior art.

Structure of the Invention In order to achieve the above object, the tummy vacaid device in the continuous casting equipment of the present invention is arranged so as to be able to rise and fall freely at an appropriate position on the slab conveyance path. The provided tummy bar guide is composed of a cam and a guide main body which is projected in the L direction from below the roll size of the roll constituting the slab conveyance path by the rotation of the gum.

Embodiment and Function An embodiment of the present invention will be described below with reference to the drawings. (1
) is the 0-ru that makes up the entire slab conveyance route l118, (2) is the 52-3 bar (52) which is placed at the appropriate place on the slab conveyance path so that it can be raised and lowered.
The winding hook (3), (4) has its proximal end fixed to the horizontal shaft (5) directly below the hook (2), and its tip has a 0-L top (
A) is a detection lever capable of protruding from below to the E force, and a tip lever (6) for abutting the tail of the tummy bar (3) is disposed at its tip. (7) A tabular blade installed slightly on the F-flow side of the t/mafunk (2), which has a pair of gums (7) fixed to the support shaft (8).
A), the fucoid frame (9) supports the cam (7A) so that it can be raised and lowered, and the L cam (7A) l: K is mounted and the gum (7A
It consists of a pair of noid bodies (7B) which are made to protrude from below to above by the rotation of the 0-ru heaven (-00). The elongated hole at the other end is a connecting rod that fits into the palm of the guide body (7B), and the kite body (7B) is connected to the gum (7A).
This was created just in case to ensure that it is linked with the above. (
1]) is a pinion fixed to one end of the support shaft (8);
) is a rack that meshes with the pinion 01), and is slidably supported by the support frame 01. α Xun is a rack (l
7-tacillinta that makes the draw 1, α ~ is an interlocking rod supported horizontally movably on a fixed frame αQ, and Qη is an interlocking bolt bolted to one end of the interlocking rod, and is formed on it. The long hole 0 machine has an arm O fixed to the horizontal shaft (5).
) is fitted into the pin at the tip of the kettle. eυ is interlocking rod αυ
This is a crank mechanism that connects the other end to the appropriate position on the outer circumference of the pinion αυ. @ is a fan-shaped frame fixed to one end of the horizontal m (5), and two strikers - are fixed thereto. (2) is a hook engagement detection limit switch provided opposite to () on the striker, and (to) is an abnormality detection limit switch provided opposite to the strike force (2).

Hereinafter, the operation of the above configuration will be explained.

The solid line in Figures 2 and 3, the solid line in Figure 4, and the solid line in Figure 5 show the table before the start of continuous casting. The upper part of the noid body (7B) is pushed up to the F side of the roll top (A). Next, start casting and Tameeba (3)
is pulled from the L-rud, thereby pulling out the slab,
The O-Meba (3) is carried eastward by the O-ru (1), and the tail part (8A) engages with the hook (2) waiting in the position shown in Fig. 4. , the tail part hits the detection roller (6), and this detection roller (6)
1) When the hook is moved and twisted, the rotation of the detection bar (4) causes the striker to hit the detection arm of the limit switch (c), and a hook pull signal is issued.

This signal does not cause the hook (2) to rise, and the hook (2) is engaged with the screw (8A), so that the tummy bar (3) is wound up. Anyway, hook (2) to Jin (8A)
If the &CVi does not engage, the tail part pushes the detection 0-ra (6) further, so the detection 'J11o-ra (6)
When is moved (α2), the striker ■ hits the detection arm of the limit switch (A) and an abnormal signal is generated. Therefore, unexpected accidents will not occur. Next, when the winding of the rack (3) begins (or after the winding is completed), the shaft cylinder α is operated to slide the rack in the direction of arrow (B). The kneading causes the pinion a→ to rotate in the direction of the arrow (C), and the cam (7A) is also rotated in the same direction via the support shaft (8), so that the protrusion of the ham (7A) rotates in the direction of the guide body (7B). ), and the guide body (7B) is shown in solid line in Figure 6.
b) It descends further downward. Therefore, there is no possibility of the slab colliding with the kite body (7B). At the same time, the detection lever (4 ) is rotated in the direction of the arrow (6), and the detection O-ra (6) is brought below the O-L top (A).Therefore, the slab is rotated between the detection O-R (6) and the detection lever (A). There is no chance of it colliding with the kite 4).Next, even if the meandering of the kite 3) is large and it collides with the guide body (7B), the kite body (7B) will be placed on the cam (7A) and Therefore, the impact force will not be transmitted to the support shaft (3), and will not damage the shaft (6), the screwdriver (6), the cylinder head (04), etc.

Effects of the Invention E As described above, according to the present invention, even if the Tammy bar collides with the guide body, the impact force is not transmitted to the gum, so the drive mechanism that rotates the cam will not be damaged. This allows damage to be kept to a minimum. The hide body is raised and lowered by a twisted cam, and the structure is simpler than conventional ones, reducing costs.
can be achieved.
