Description

[Detailed description of the invention] This invention is used in steel manufacturing processes, etc. This invention relates to an automatic destruction device for breaking the lining bricks lined in ladle and other ladle for processing molten metal.

As is well known, this type of molten metal processing pot has an iron shell lined with permanent bricks, and a lining brick is attached to the inside of the permanent bricks.

When the lining bricks become worn and damaged with use, only the lining bricks are replaced with new ones.

By the way, this lining brick destruction work has traditionally been carried out by
A worker enters the pot and uses air braking power.

However, this work is extremely hard labor in heat and dust.

For this reason, automatic destruction devices that mechanically destroy lining bricks using robots have recently been provided.

However, when destroying the lining bricks, care must be taken not to destroy the permanent bricks, and conventional automatic destruction devices lack technical consideration in this respect.

The present invention is an automatic pot lining brick that can reliably destroy only the lining brick without destroying the permanent brick, and is equipped with a control means that has an extremely simple structure on the device and can be manufactured at low cost. It seeks to provide a destructive device.

In order to achieve this purpose, the automatic destruction device according to the present invention fixes a bracket that moves forward and backward together with the air braking force, and a rod extends parallel to the striking blade of the air braking force to remove the bricks lining the pot wall. A hydraulic cylinder that can move forward and backward with respect to the bracket and can be fixed at a fixed position with respect to the bracket is fixed to the bracket, and a stopper is fixed to the tip of the rod, and further, the rod pressing force of the hydraulic cylinder is set to the air brake force. The rod pressing force of the hydraulic cylinder is set to be larger than that of the hydraulic cylinder, so that when the air brake force has finished destroying the lining brick, the tip of the stopper of the hydraulic cylinder rod fixed to the bracket will come into contact with the unbroken surface of the lining brick. It is characterized by the fact that by operating the airbrake force, the blowing blade of the airbrake force does not advance any further.

The present invention will be described in detail below with reference to the illustrated embodiments.

FIG. 1 shows the entire destruction device.

First, the overall outline of this automatic destruction device will be explained.

In FIG. 1, reference numeral 1 denotes a pedestal, and a base 2 of the destruction device is placed on this pedestal 1.

Is there a spiral on the base 2? A table 3 is placed thereon, and this swivel table 3 can be rotated with respect to the base 2 by a drive motor 4.

A support 5 is erected on the swivel base 3, and an arm 6 is connected from the support 5.
, and an arm 7 is connected to the arm 6.

Hydraulic cylinders 8 and 9 are attached to these arms 6 and 7, respectively.

These hydraulic cylinders 8 and 9 are driven by a hydraulic unit 10 installed on the swivel base 3, and can freely expand and contract the arms 6 and 7.

A hydraulic motor 11 and a bracket 12 are attached to the lower end of the arm 7.

A guide rail 13 is attached to the lower end of the bracket 12,
An air breaker 14 is installed on this guide rail 13.

As shown in the figure, the above-mentioned destruction device has a rotating motor 4.
By operating the cylinders 8 and 9, the air breaker 14 can be set at any position within the pot wall 15 consisting of the iron skin 15a, permanent brick 15b, and lining wall 15C.

Next, the main parts of the present invention will be explained in more detail based on FIGS. 2 and 3, I and II.

A hydraulic cylinder 16 is installed between the guide rail 13 and the bracket 12, and the setting angle of the guide rail 13 with respect to the bracket 12 is adjusted by this hydraulic cylinder 16.

The guide rail 13 is provided with a long hole 17 in its longitudinal direction, and the wheels 18a, 1 of the air breaker 14 are inserted into the long hole 17.
8b is fitted and runs.

A bracket 19 is fixed to the air breaker 14, and the tip of a rod 21 of a hydraulic cylinder 20 provided on the guide rail 13 is fixed to the bracket 19.

The air breaker 14 can move forward and backward relative to the pot wall 15 by moving the rod 21 of the hydraulic cylinder 20.

A hydraulic cylinder 22 is now fixed to the bracket 19, and its rod 23 is arranged parallel to the striking blade 14a of the air breaker 14.

A stopper 24 having a spherical end face is fixed to the tip of the rod 23 as shown in FIGS. 3I and II.

Incidentally, the gap 11 between the stopper 24 and the blowing blade 14a of the air braking force is slightly larger than the width dimension 1 of one lining brick.

Now, in order to destroy the lining brick 15C of the pot wall using the above-mentioned destruction device, the air breaker 14 is inserted into the pot wall 1.
5, and the stopper 24 of the hydraulic cylinder 22 is sequentially moved in a direction in which it always comes into contact with undestructed bricks to destroy them.

Before starting the destruction work, the position of the rod 23 is set so that the parallel distance between the tip of the stopper 24 and the tip of the blowing blade 14a of the air brake force is equal to the thickness of the lining brick 15C.

The pressing force of this rod 23 is set to be greater than the rod pressing force of the cylinder 20.

In this state, the hydraulic cylinder 20 is operated to move the bracket 19 forward, and the blowing blade 14a of the air brake force destroys the lining brick 15C.

At the same time as the destruction of the lining brick 15C is completed, the stopper 24 comes into contact with another undestructed lining brick and stops the air breaker 14 from moving further.

Since the stopper 24 always comes into contact with the undestructed brick, the air breaker 14 can be reliably stopped.

In addition, since the tip of the stopper 24 has a spherical shape, even if the blowing blade 14a of the air brake force contacts the pot wall 15 at a slight angle, the tip of the stopper 24 will surely contact the lining brick. I can do that.

The rod 23 to which the stopper 24 is fixed may be adjusted by using a multistage cylinder type cylinder 22 or by using a potentiometer type.

According to the pot lining brick breaking device of the present invention, it has an extremely simple structure of just installing a racket on the air breaker and a hydraulic cylinder on this racket, and can destroy only the lining bricks and avoid damage to the permanent bricks. and achieve the intended purpose.
