Description

Guide for segment fixing of instrument {Guide for segment fixing of continuous caster}

The present invention relates to a guide for joining the segment of the player, and more particularly, for the segment joining of the player which can quickly join the segments by allowing the segment to rotate along the curved part of the player by the weight of the segment. It's about a guide.

Generally, when producing molten steel in molten state contained in a tundish, a caster having a predetermined width and thickness is used as shown in FIG. 1, and a plurality of (about 19 pieces) are used at the lower part of the instrument to guide the cast. Segment S) is provided to form a vertical curved portion.

Since the segment (S) guides the hot slab, it must be regularly repaired and replaced. In this case, the segment (S) is removed from the player and mounted.

In this way, when detaching and mounting the segment S, the pair of guides 1 are coupled to the player and the wires 2 are gradually pulled with the segments S seated on the guides 1. Or unscrewing and mounting the segment (S).

Since the player is a vertical curved type, the first to seventh segments S from the upper side of the plurality of segments S are located in the curved portion, so that the center of gravity acts downward and always sags downward. ), The cotter pin (3) is separated smoothly, but when mounting the segment (S), the center of gravity acts as a lower portion so that the cotter pin (3) in the insertion hole (4) formed in the segment (S) There was a problem that this is not combined smoothly.

In order to solve this problem, as shown in FIG. 2, the hydraulic jack 5 is installed on the upper surface of the segment S installed in the lower part, and then the hydraulic jack 5 is operated to insert the hole formed in the segment S. As shown in FIG. (4) is fitted to the cotter pin (3) to join the segment (S).

However, this conventional method requires a separate hydraulic jack (5) is required to combine the segment (S), so the work time was excessively excessive due to the work to install and operate the hydraulic jack (5) as well as safety accidents There was a problem such as is generated.

The present invention has been invented to solve the above problems, the object is that the insertion hole formed in the segment is rotated by the weight of the segment as the segment is moved along the guide when coupling the segment to the player cotter pin It is to provide a guide for joining the segment of the player to be able to quickly perform the joining operation of the segment by exactly matching to.

Referring to the characteristic configuration of the present invention for achieving the above object is as follows.

The guide for joining the segment of the player of the present invention is a stopper which is mounted on a fixed plate installed in the player is moved by the driving means so as to fix the support bar, the guide bar is installed along the player to the front end, the support bar; Rotating bar is built in the insertion groove formed on the top end of the support bar is rotated around the hinge, and the spring is provided between the pivoting bar and the insertion groove resiliently installed.

Referring to the present invention having such characteristics in detail as follows.

Figure 3 is an exploded perspective view showing a guide for joining the segment according to the invention, Figure 4 is a cross-sectional view of the coupling state showing the guide for joining the segment according to the present invention.

As referred to herein, the present invention includes a guide groove 6 formed in the player at the distal end of the support bar 10 for guiding the segment S when the segment S is coupled to and separated from the player. The guide roll 11 is rotated in the inserted state is installed, the drive means 20 is installed on one surface of the support bar 10, the electric drive is installed as the drive means 20 The screw shaft 22 is provided in the rotating shaft 21 of the electric motor, and the screw shaft 22 is screwed to the stopper 30.

The stopper 30 is to fix the support bar 10 so that the support bar 10 does not flow when the segment S is coupled and separated, and the tip end of the stopper 30 is seated in the guide groove 6 of the player. The plate 7 is provided.

In addition, an insertion groove 12 is formed on an upper end of the support bar 10, and a support piece 13 is formed to protrude upward from the bottom of the insertion groove 12, and the support piece 13 is pivoted on the support piece 13. Protruding pieces 41 formed on the bottom of the bar 40 are coupled via the hinge 14.

And between the rotation bar 40 and the insertion groove 12, a spring 50 for imparting an elastic force to the rotation bar 40 is elastically installed.

Referring to the operating state of the present invention configured as described in detail as follows.

First, when coupling the segment (S) to the player, the support bar 10 is positioned at a position to which the segment (S) is to be coupled, and the support bar (10) is a guide groove (6) formed in the player When the support bar 10 is moved as described above, the support bar 10 is rotated in the state where the guide roll 11 installed at the distal end of the support bar 10 is inserted into the guide groove 6. ) Moves smoothly.

When the position of the support bar 10 is adjusted through the above process, the driving means 20 is operated to prevent the support bar 10 from flowing. When the driving means 20 is operated, the rotating shaft 21 and the screw shaft 22 installed on the rotating shaft 21 rotate, so that the stopper 30 screwed to the rotating shaft 21 is a guide groove 6 of the player. ), The stopper 30 stops the driving means 20 when the stopper 30 is seated on the fixed plate 7.

In this state, as shown in FIG. 5, the guide rolls 9 installed on both sides of the segment S are seated on the upper surface of the support bar 10, and the wire 2 connected to the segment S is released. (S) is to be moved while being guided by the support bar 10 by its own weight.

As the segment S is moved, as shown in FIG. 6, the rotating bar 40 is not rotated until just before the pair of guide rolls 9 are seated on the upper surface of the rotating bar 40. Insertion grooves 12 formed in (S) is to be in a state close to the cotter pin (3).

At this time, when the wire 2 is further loosened, the pair of guide rolls 9 installed on the segment S are seated on the upper surface of the rotation bar 40, and the rotation bar 40 is hinged as shown in FIG. 7. Since the pivot (14) is rotated about the center (14) is rotated together, the cotter pin (3) is smoothly inserted into the insertion groove 12 formed in the segment (S).

As described above, the present invention is characterized in that the segments are smoothly coupled to the cotter pin as the segments are rotated by their own weight according to the curved portion of the player when the segments are coupled to the player, so that the segments can be quickly combined without any additional work. Has the effect of.
