Description

Kinematic device for injecting sand into the ladle outlet

The present invention relates to a device for injecting sand into the SLIDING NOZZLE of the ladle, and more particularly, it is easy to operate only by human force based on the kinematic principle by the BALANCE WEIGHT. The present invention relates to a device capable of simplifying the work and process of sand injection and simplifying the facility by simple equipment itself as a possible device.

In general, ladles, which are containers needed to transport and store molten steel of high temperature (about 1300 ° C or more) in steelmaking and steelmaking processes, have holes for ejecting molten steel in the lower part. When molten steel is charged into the tundish of the instrument through this hole, sand is charged into the water outlet after each use.

Conventionally, in the apparatus for injecting sand into the ladle water outlet as shown in Figs. 7 and 8, the wire rope 180 is mounted on the sieve tower assay part 100 and the lower end of the sieve tower assay part 100. The filler tube assay unit 160 having the filler tube 200 installed thereon is provided with a tube guide support 260 formed on the filler tube assay unit 160 and the sieve tower assay unit 100 and the filler tube assay unit. The handle 220 is positioned between the 160.

The hopper assay part 120 is installed at one side of the lower end of the sieve tower assay part 100, and a gate 240 is formed at the lower end of the hopper assay part 120, and the traveling device assembly is located at one side of the hopper assay part 120. The shae 140 is formed, and the rail 280 is installed at the bottom of the traveling device assay 140.

The rail 280a by the rail support 300 is installed at the upper part of the traveling device assay unit 140, and the upper support roller 320 and the cable trolley 340 are formed at one side of the rail 280a, and the frame ( The motor 400, the hoist 420, and the control panel 380 are installed inside the 360, and the end support roller 440 is mounted as the bearing unit 500.

In the accompanying drawings, reference numeral 460 denotes a side glass, and 480 denotes a cam unit.

However, the conventional apparatus as described above has an uneconomical problem due to the expensive equipment cost compared to the function by moving the storage tank (HOPPER) using mechanical and electrical operating devices (MOTOR & HOIST).

The present invention has been made to solve the above problems, and its purpose is to enable the operation of the sand filling (SAND CHARGING HOPPER) smoothly by using pure mechanical force without using mechanical and electrical operation device kinematic principle It is to provide a kinematic device for injecting sand into the ladle water outlet.

The present invention achieves the above object by adjusting the center of gravity to easily move the center of gravity (ROPE PULLEY ASS'Y) and small force to easily move the tank (HOPPER) by the rope (ROPE) This is achieved by providing a BALANCE / COUNTER WEIGHT and SAND CHARGING HOPPER ASS'Y, which serves as a path to move the sand.
