Description

[Detailed description of the invention] Industrial application field: This invention enables efficient stacking of large bricks, which is difficult with conventional construction methods, when constructing lining bricks for converters and various refining vessels. It is related to the device.

Background of the idea: In various types of kilns and refining vessels, permanent bricks are applied to the iron skin, and block-shaped refractory bricks are also piled up. The bricks that form these linings are
It is a block body shaped to follow the construction area, and the stowage on the bottom or the circumference of the refining container is carried out using open joints without using joints, except in specific cases. In particular, since the lining bricks are conventionally laid by hand, they are divided into small pieces and stacked in two layers, but if the bricks become eroded, the bricks at the joints may fall off. In order to prevent this, there is a recent trend toward single-layer stacking, longer lengths, and larger sizes.

As the bricks have become larger and larger, it has become impossible to stack them by hand using only human power, and mechanical equipment has come to be used to stack these large blocks of bricks.

Prior art: As a device for lining a converter with bricks, for example, as disclosed in Utility Model Publication No. 51-19604, there is a vertical conveyor for carrying the bricks into the converter, a suitable beam for setting the bricks at the loading place, and the like. Many have a combination of the following. Furthermore, methods for positioning the bricks by rolling them on a roller shelf, setting them with a clamping arm, or moving them using a suction cup have been reported. However, these conventional devices have become larger to keep pace with the increasing size of lining bricks.
Furthermore, the mechanism for stacking bricks in close contact with each other has become complex, and may not be applicable depending on the installed state of the target furnace, or may be structurally difficult to construct at or near the bottom of the furnace. .

Purpose of the invention: In view of the current situation, this invention was made to solve the above problems, and it is possible to perform visual operation without being restricted by the installation conditions of refining vessels, etc., and with a minimum human load. The purpose of this invention is to provide a stacking device for lining bricks.

Structure/Example of the invention: Hereinafter, one embodiment of the invention will be described based on the drawings.

As shown in FIG. 1, the brick laying device 10 of the present invention exhibits an excellent function in laying bricks 21 at the bottom of the converter 1. The refining vessels, including converter 1, are made of iron shells and
A bottom brick 21 and a side brick 22 are stacked inside the permanent brick 2, and lining is performed. At this time, in the present invention, a hoist rail 4 is provided in the upper space of the converter 1 installed in a normal state, and the bricks 20 are carried into the converter 1 by the hoist 3 that moves along with the hoist rail 4. Work can proceed smoothly even in tight spaces.

Inside the converter 1, there is provided a square or circular frame frame 11 such as a cross-shaped frame, and a main girder 11' which has almost the same shape as the frame frame and which is mounted on the frame frame 11. A balance arm 16 that can freely move laterally is attached via a drive trolley 15 of the type. The frame frame 11 is connected to a suspension chain 13 from a suspension part 14 such as a chain block secured to a beam spanning the opening of the converter 1.
It can be hung at the desired hanging height. As shown in FIG. 2, a plurality of outriggers 12 are provided on the frame 11 to protrude in the radial direction, and the ends of the outriggers 12 are extended and brought into contact with the inner wall surface of the converter to prevent horizontal movement. to bound. Therefore, the frame frame 11 can maintain and fix the required vertical height and horizontal position by the weight of itself and the balance arm 16, the length of the suspension chain 13, and the extension of the outrigger 12.

The drive trolley 15 with the balance arm 16 attached thereto as described above is attached to the main girder 11' of the frame frame 11, and one or more swingable vacuum suction cups 17 are attached to the tip of the balance arm 16. This balance arm 16 has a rotatable base shaft that is attached to the drive trolley 15, and has several hinges, and the position of the tip of the balance arm 16 has a large degree of freedom within the entire length of the arm. Furthermore, a counter spring or sub-arm is attached to each hinge part or between the hinge parts, and the torque derived from these counteracts the load of the brick held by the vacuum suction cup 17 at the tip, maintains its original shape in an equilibrium state, and at the same time balances The arm 16 can be turned or deflected using a small amount of additional force on the order of human power.

A manipulator 18 is attached near the tip of the balance arm 16 or at an appropriate location. The manipulator 18 controls suction and release of the vacuum suction cup 17 and movement of the drive trolley 15 forward and backward along the main girder 11'. Air piping to the vacuum suction cup 17, electrical wiring to the drive trolley 15, etc. are not shown.
Furthermore, if the outrigger 12 that restrains the frame frame 11 is of a fluid pressure or screw type, and the suspension part 14 is of an electric type, the position of the frame frame 11, that is, the main girder 11' can also be adjusted by the manipulator 18. It is possible.

Effects and Effects of the Invention: The brick laying device 10 of the present invention having such a configuration can be moved to an appropriate height position in the target converter 1 by the suspension part 14, the suspension chain 13, or the outrigger 12 during actual use. to take root. Next, using the hoist 3, the large block-shaped lining bricks 20 are carried into the converter 1. The bricks 20 can be directly unloaded to the bottom of the furnace at the beginning of the work, and after the work has progressed to a certain extent, they can be unloaded onto the bottom bricks 21 that have already been stacked.

In this state, the operator inside the furnace operates the manipulator 18 to move and move the balance arm 16.
It is steered and the required brick is sucked and held by the vacuum suction cup 17. By handling the bricks 20 via the balance arm 16, even large block-shaped bricks can be handled freely and safely.
It is possible to align the bricks at desired locations and stack them without creating gaps between the bricks or making the bricks unstable. After the bottom bricks 21 are stacked, a smooth transition can be made to the side bricks 22.

Furthermore, since the brick laying device 10 can be easily disassembled and assembled into the main structural parts to be formed, during construction, the brick stacking device 10 is brought into the furnace using the hoist 3 in a disassembled state and assembled. An advantage of the present invention is that the process can be reversed after construction and the work can be carried out easily.

When using the brick stacking device of the present invention, the human labor load is greatly reduced, so it is possible to stack large blocks of bricks in refining vessels, etc., which have open joints but are tightly packed to prevent molten metal from entering. ,
It improves work efficiency and has great industrial applicability.
