Description

[Detailed description of the invention] The present invention relates to a swing tower.

A conventional swing tower will be explained based on FIG. 1.

1 is a mold, 2 is a tundish, 3 is a tundish nozzle stopper, and 4 is a swing tower, which includes a single tower 5 and a swing disposed on the single tower 5 so as to be able to freely rotate around a vertical axis. An arm 6, a total of eight cylinder devices 8, two cylinder devices 8 each disposed at both ends of the arm 60, sandwiching notches 7 formed at both ends of the arm 6, and both cylinder devices 8 in each group. A pair of elevating frames 9 disposed on the piston condo 8a of the cylinder device 8, a pair of trunnions 10a protruding from the outer peripheral surface, and a ladle 10 placed on each of the elevating frames 9, and a guide post 11. Each frame 9 is provided under each of the above-mentioned elevating frames 9.
A weighing device (not shown) is placed to receive 100 weights per dollar.

In such a conventional swing tower, when each cylinder device 8 is operated to extend each piston rod 8a and raise the elevating frame 9 and ladle 10, the connection with the weighing device is severed, making it impossible to weigh. have a problem

Therefore, the present invention provides a swing tower that solves these problems.

An embodiment of the present invention will be described below based on the drawings.

In this embodiment, the same parts as those shown in FIG. 1 are given the same part numbers, and the explanation will be omitted.

12 is a revolving body with a rectangular planar shape that is disposed on a single tower 5 so as to be freely rotatable around a vertical axis, and each one costs $10.
Four portions 12a are formed at locations corresponding to .

Reference numeral 13 denotes a set of two arms, a total of four arms, and the two arms 13 of each set are parallel to each other, sandwiching the respective recesses 12a, and the base ends are connected to the pins 15 on the brackets 14 on the revolving body 12. The tips are rotatably supported through the
The revolving body 12 also protrudes outward and extends above the tundish 2.

Reference numeral 16 denotes a rectangular hole formed at the tip of each arm 13 along the vertical direction from the upper surface to the center, and the surface corresponding to the ladle 10 is open.

17 is a pair of guide grooves formed along the vertical direction on the inner circumferential surface of each of the square holes 16; 18 is a pair of guide grooves formed in the inner peripheral surface of each of the square holes 16;
Each frame 18 has a trunnion 10a on top of which it is vertically movable.
is listed.

A guide rod 19 is fixed to each of the seven frames 18 and slidably inserted into each guide groove 17.

Reference numeral 20 denotes a hole 2 whose main body is formed under each of the square holes 16.
The piston rod 20a is a cylinder device that is arranged and fixed inside the lift frame 18, and the tip of the piston rod 20a comes into contact with the lower surface of the lift frame 18.

Reference numeral 22 indicates a protrusion extending horizontally from both sides of the central portion of each arm 13, and reference numeral 23 indicates a load cell disposed on the revolving body 12 below each protrusion 22. The sensing protrusion of each load cell 23 23a is in contact with the lower surface of each projection 22 and receives a weight of 100 centimeters through the arm 13, cylinder device 20, guide rod 19 and lifting frame 18.

As described above, according to the swing tower in the continuous casting equipment of the present invention, the swinging body is provided with a weighing device that receives the weight of one dollar through the arm, and the ladle is placed on the arm through the lifting device. Therefore, it is possible to accurately weigh the weight regardless of the operation, not only when the lifting device is not operating, but also when the lifting device is activated and the ladle is raised. This completely eliminates the problems of the conventional method.
