The present invention relates to a ladle movement detecting apparatus, and specifically, when a flame or dust generated during a process of charging molten iron from a ladle to a converter may obstruct a vision of a converter driver or a crane driver, the state of the ladle may be checked. It relates to a ladle movement detection device.

In general, hot metal produced in a blast furnace is transported to a dog house by a chartered bogie in a ladle, and the molten iron transported to the dog house is transferred to the ladle and the ladle. Together, it is hoisted by a crane, charged into a converter, and then produced into molten steel through a degassing and decarburizing process.

In more detail, the ladle loading process is carried out by the crane's sovereign hook, and the ladle raised to a certain height is inclined by the boring hook to charge the charter to the converter. At this time, the crane driver and the converter driver check the coupling state of the hook and ladle and the charging process of the molten iron with the naked eye or a camera to notify each other with a radio signal and adjust breathing.

By the way, check the coupling state of the ladle and the charging process of the charterer through the naked eye or camera, it takes a lot of time, and if the flame or dust occurs during the charterer, the visual confirmation is not easy to cause instantaneous judgment and confusion. have.

Therefore, when the operator or the driver tilts the ladle in a state in which the hook is not correctly identified, as shown in FIG. 1A, the ladle L falls to the ground while the hook h is separated from the trunnion t. Large accidents can occur.
In addition, when the tilting speeds of the converter C and the ladle L do not coincide with the charter loading, as shown in FIG. 1B, the pelican mouse M of the ladle L is the furnace ball of the converter C. By being stuck to m), it can be pushed out of the furnace (m) and a large accident can occur.

Therefore, the present invention is to solve the above-mentioned problems as the ladle movement detection that can prevent large accidents by checking the latching state of the hook and the loading state of the molten iron which is difficult to check with the naked eye when the ladle hoisting and chartering To provide a device.

When the trunnion t rises in the direction of the first arrow X in the drawing in the initial state of the sensing process, one end of the sensing rod (part in which the coupling bar is formed, 130a) is raised with the trunnion t and sensed. The other end of the rod 130b descends with the connector 150 as the central axis. The lower sensing rod other end 130b presses the contact bar 142 of the lift sensing unit 140a to generate a signal, and the generated signal is displayed to the display unit 106 provided in the tilt chamber 104 and the crane driver's seat. Delivered to indicate that the ladle has been raised.

On the other hand, when the trunnion (t) in the initial state moves in the direction of the second arrow (Y) of the drawing, the one end 130a of the sensing rod in the front direction (the second arrow direction) together with the trunnion (t) The contact bar 134 moves in the rear direction with the connector 150 as the central axis. The moved contact bar 134 presses the contact bar 142 of the slide detecting unit 140b to generate a signal, and the generated signal is transmitted to the display unit 106 provided in the tilt chamber 104 and the crane driver's seat. Indicates that the ladle has moved in the front direction.

As described above, although the configuration and operation of the ladle movement detecting apparatus according to the preferred embodiment of the present invention are shown in accordance with the above description and drawings, this is merely an example and the scope does not depart from the spirit of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made therein.
