Anchor chain guide mechanism for ladle conveyance

Abstract

There is provided a guide mechanism of an anchor chain for conveying ladles, which can prevent an anchor chain from being twisted or sagged and can transmit motive power to the anchor chain reliably and efficiently. A linear anchor chain guide 30 is provided in a motive power transmission region where the motive power is transmitted from a conveyer chain 21 to the anchor chain 10, and the anchor chain 10 is introduced and guided to the anchor chain guide 30. The guide side parts 32 in the left and right guide half members 31, 31 constituting the anchor chain guide 30 can limit a leftward or rightward movement of the anchor chain 10. The guide upper parts 33 can limit an upward movement of the anchor chain 10. A downward stopper 13 placed at the upper end of each vertical unit ring 11 of the anchor chain 10 cannot pass downwardly through the clearance 34 set between the guide upper parts 33, 33 of the left and right guide half members31, 31, so a downward movement of the anchor chain 10 can be limited. In the motive power transmission region, a conveyer chain guide 40 is also provided for preventing the conveyer chain 21 from floating and the like.

Description

technical field [0001] The present invention relates to an anchor chain guide mechanism for ladle conveyance, and more specifically relates to an anchor chain for conveying a ladle receiving a product (calcium carbide) from a calcium carbide manufacturing furnace along a circular track to a power transmission The guide mechanism in the area and conducts the guide. Background technique [0002] Calcium carbide (hereinafter referred to simply as carbide) is made by heating a mixture of lime and coke to over 2000°C in an electric furnace. Products melted in the furnace are successively received by multiple ladles from the outlet of the furnace, and these ladles are transported to the product processing area away from the furnace. In the product processing area, the product is unloaded from the ladle using an overhead crane or the like, and the product is further cooled or pulverized. Ladles that become empty in the product handling area are conveyed again to the tap opening o...

AI Technical Summary

Problems solved by technology

Such a heavy anchor chain sometimes twists or sags in the area where the power is transmitted from the drive unit to the anchor chain. In this case, the power cannot be efficiently transmitted to the anchor chain.

In addition, if the position of the transmission chain of the driving device is shifted, the engagement with the anchor chain will fail, and in this case, the efficiency of power transmission to the anchor chain will also decrease.

In addition, in order to improve the efficiency of taking out products, the current mainstream method is to use a circular furnace with three outlets at intervals of 120 degrees in the circumferential direction. A sharp turn, such as slack in the anchor chain on the sharp turn, can also cause twisting of the anchor chain in the power transmission area, etc.
