Grab-bucket ship unloader and operation method thereof

Abstract

The invention relates to a grab-bucket ship unloader and an operation method thereof. When the grab-bucket ship unloader is used for unloading, the opening limit and the closing limit of a grab bucketare set according to the characteristics of material goods, so that the grab bucket can better grab the material goods; and the hoisting height of the hatch height is set, so that a sufficient safetydistance between the grab bucket and a cabin is kept when the grab bucket is lifted to move to a wharf, and the position of the outside of the cabin and the position of the inside of the cabin are set so that the grab bucket can reliably grab the material goods in the cabin; and after the parameters are set, a control device controls a walking crane and the grab bucket to cycle back and forth according to the set parameters, and then the material goods are released into a storage hopper after the material goods are grabbed from the cabin and conveyed above the storage hopper on the wharf. Therefore, by means of the grab-bucket ship unloader and the operation method thereof, the material goods can be automatically unloaded, and the operation is efficient and reliable.

Description

technical field [0001] The invention relates to a grab ship unloader and an operation method thereof. Background technique [0002] There is no standard for semi-automatic circulation hatch setting and grab opening and closing limit setting. During the setting process of grab opening and closing limit, due to the different setting habits of field operators, the setting of grab opening and closing limit is also different. If If the closing limit of the grab is set too tight, it will easily cause the twitch of the opening and closing wire rope when the grab is closed, which will affect the automatic cycle time; if the closed limit of the grab is set too loose, the closing delay of the grab will also affect the automatic cycle time (closing time). During the setting process of the automatic circulation hatch, due to the difference in the height setting of the cabin along the inner side, the outer side and the cabin, the automatic circulation track is shorter (the cycle time is...
