Tail car connecting and separating device and connecting and separating method of stacker-reclaimer

Abstract

The subject of the present invention is a stacker / reclaimer (1) that is formed from connecting a tripper (6) and that hoistably and rotatably supports a boom (5) at a traveling girder (3) that travels over rails (2). The stacker / reclaimer is provided with: a connector (70) that separably connects the tripper (6) to the traveling girder (3); a tripper holding means (for example, a storm anchor (63)) that holds the tripper at an anchoring position; and a tripper holding detection means (for example, a limit switch (63a)) that detects that the tripper (6) is being held by the tripper holding means. The operation of separating the connector (70) can be performed only when the held state of the tripper (6) is detected. As a result, the tripper (6) can be safely and reliably separated from and then reconnected to the traveling girder (3) without relying on visual confirmation by a worker.

Description

technical field [0001] The present invention relates to a stacker-reclaimer (stacker-reclaimer) that doubles as a stacker that accumulates bulk materials such as coal in a stockyard and a reclaimer that continuously takes out and sends out the full bulk materials. ), a device for separating or connecting a tail car (tripper) used in stacking, and a method for separating or connecting it. Background technique [0002] In the past, for example, in the loading and unloading facilities of the wharf and ironworks, the bulk materials such as ore and coal that were imported were piled up and stored on the stockyard, and the stacker for the accumulation and the bulk material delivery were also used. So-called stackers and reclaimers are well known. The stacker-reclaimer has a traveling body running on a rail extending along a stockyard, a rotating body rotatably provided thereon, and a boom (boom) supported on the rotating body so as to be pitchable. A bucket wheel (bucket wheel) ...

AI Technical Summary

Problems solved by technology

Therefore, the pitchable and rotatable range of the boom is generally limited to prevent interference, resulting in a decrease in operating efficiency

[0006] In addition, the trailer that is not in use is separated from the traveling body at the time of sending out, but in fact, the work of separating and connecting takes time and labor, and the avoidance of collision regardless of the movement of heavy objects depends entirely on the visual confirmation of the operator. , and there is a possibility of collision due to operator fatigue and weather
