Description

Multi-joint remnant opening machine universal moving device

The present invention is to move the remnant open air through the remnant opening installed to discharge the melt composed of molten iron and slag stored in the Main Iron Runner and Pond of the Blast Furnace. It is a universal moving device of articulated remnant open air. More specifically, the device fixed to the side of the remnant opening is operated hydraulically, so that the remnant opening can be freely moved to any of the remnant openings or wired pond outlets. It relates to a universal moving device of the articulated residual air opening through the.

In general, the melt produced in the furnace is discharged to the large tap water through the outlet 1 as shown in FIG. 1, and the discharged melt is stored for a predetermined time in the large tap water (2) to reduce the specific gravity. The molten iron is separated into pig iron and slag, and the molten iron flows into the molten iron, and the slag flows into the wired pond 5 through the exhaust port 4 to separate the molten iron that is not completely separated in the molten iron once again. It flows along the tap water 6 to a treatment plant. As such, the large hot water and the wired pond 5, such as a container in which the melt is stored, are constructed with the refractory 21, and since the melt is always stored therein, it is impossible to check the wear and erosion of the refractory. For the purpose of discharging the residual melt in the large hot waterway (2) through the large hot water remnants (7), and the wired pond (5) through a plurality of molten iron pond discharge port (8) a day to recover the collected molten iron Drain the molten iron.

Residual melt discharge operation inside the large bathway (2) is installed by moving the residual open air (10) shown in FIG. 2 by a crane in the front of the large open water (2) residual line (7) and the residual open air (10) By using the drilling bit (11) to penetrate the residual hole (7) to discharge the melt.

However, there is no way to fix the movable residual open air 10 in the wired pond discharge port 8 and there is not enough space to penetrate the outlet by the residual open air so that 100% manual oxygen opening work is performed to melt the melt. It is discharged | emitted to the residual water line 9. On the other hand, in order to discharge the residual melt inside the large bath (2) to the mobile residual open air, it is necessary to open a plurality of the cover, and also a lot of preparatory work such as opening the cover to remove the residual melt inside the wired pond (5).

Therefore, the discharging work of the large melt (2) and the discharging of the wired pond (5) are difficult to prepare and discharge the melt of high temperature (over 1500 degrees). The high and long working time, as well as the heavy work load, particularly caused the pollution of the surrounding environment due to the generation of large amounts of dust during the oxygen opening work.

The present invention has been made to solve the problems of the prior art as described above, and the pivot shaft is installed in the horizontal direction to the vertical axis to move up and down, and the pivot shaft is geared to match the gear of the swing motor and , A screw shaft for penetrating through the mounting members attached to the upper end and the lower end of the central shaft and moving the pivot arm up and down by the rotation of the moving motor, and the cylinder shaft mounted on the side of the pivot arm. Provided is a universal moving device of a multi-joint residing open air consisting of a guide coupled to, and a residing open air rotatably attached to the lower portion of the rotating shaft.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing the universal moving device of the articulated residual air opening of the present invention.

3 is a perspective view showing the present invention, the base iron plate 101 is fixed on the columnar bottom and the central shaft 102 is installed on the base iron plate, and the pivot rock is movable up and down in the horizontal direction from the central axis ( 110 is installed and the guide 115 is attached to the lower side of the swivel rock 110 through a plurality of rollers 116, the residual air opening 10 having a rotating shaft 117 at the lower portion of the guide 115 Is installed. In addition, a gear 105 is installed below the central shaft 102 to rotate the pivotal arm 110 by the gear 104 of the central shaft pivoting motor 103, and the members 120 mounted on the upper and lower portions of the central shaft 102. And a screw shaft 109 for moving the pivot arm 110 up and down through 121, which is connected to the gear 107 of the motor 106 mounted under the member 120. It is rotated by the gear 108 of the coupled screw shaft to move the swinging arm 110 up and down. The guide 115 is moved forward and backward by a cylinder 111 installed horizontally on the lower side of the swivel arm 110, and the gear 114 and the gear of the rotating motor 112 are installed on the open air shaft 117 of the lower guide. 113, the residual open air 10 is configured to rotate left and right.

Hereinafter, the operation of the large hot water remaining after opening 7 or wired pond discharge port 8 through the remnant open air universal moving device of the present invention will be described.

First, by turning the turning motor 103 of the central axis 102 to turn the turning arm 110 to the desired place, and then by operating the cylinder 111 to move the remnant opening air 10 to the desired distance and open air rotary motor (112) is operated so that the large hot water remnant line 7 and the residual open air 10 are aligned in a straight line (when penetrating the wired pond discharge port 8, the wired pond discharge port is aligned with the residual open air in a straight line), turning When the arm up and down movement motor 106 is operated, the screw shaft 109 is rotated to move the pivoting arm 110 downward so that the hook 14 installed in the remnant opening air 10 is the hook for the retreat of the large waterway 7. ) And then advances the body 15 of the remnant opening air 10 and penetrates the remnant opening 7 with the excavation bit 11.
