Abstract

PURPOSE:To convey objects to be conveyed such as bulk materials from a very deep place of up to a very high place by constituting a bucket conveyor of brackets connected to respectively corresponding links of an anchor chain, buckets fixed to the brackets and sprockets to convey the chain. CONSTITUTION:In a vertically constructed derrick 1, a sprocket 3 driven in rotation by means of a motor 2 through a chain power transmission mechanism is supported on a shaft in the oblique upward direction from the upper edge, and sprockets 5 and 6 setting as guides to bend an anchor chain in the oblique upward direction are also supported in the upper part, and a sprocket 7 is supported in the lower part as well respectively with the shafts, and an endless anchor chain 4 guided by means of the sprockets 5 and 6 is spanned betwen the upper and lower sprockets 3 and 7 so as to be circularly driven by means of the motor 2. Next, when the sprocket 3 is driven in rotation by means of the motor 2, the chain 4 is driven circularly in the arrow direction, and a bucke 13 loaded with earth and sand by means of a belt conveyor and/or the like in the lower part ascends to the upper edge of the derrik, and then changes its direction, and by being turned upside down by means of the sprocket 3, the earth and sand can be discharged.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket conveyor that uses an anchor chain and is suitable for transporting objects such as powder or granules from great depths or to very high places.

0002

[Prior Art] Bucket conveyors are known for vertically conveying objects such as powder and granules. Conventional bucket conveyors have a structure in which buckets are connected to plate-shaped links of a roller chain via brackets. ing.

0003

[Problems to be Solved by the Invention] Due to the strength of the roller chain, the conventional bucket conveyor described above can only transport objects such as powder and granules up to a height of several tens of meters at most, and it is difficult to carry objects on the seabed. It cannot be used for purposes such as transporting earth and sand when excavating deep seabeds or deep wells.

[0004] An object of the present invention is to provide a bucket conveyor that can also be used for the above-mentioned purposes.

[0005]

[Means for Solving the Problems] Therefore, the bucket conveyor of the present invention includes a pair of endless anchor chains, and both ends of the anchor chains arranged in parallel are connected to corresponding links of the anchor chains on both sides at predetermined intervals. a bracket; a bucket fixed to the bracket;
It consists of a sprocket that engages with the links of the anchor chain and feeds the anchor chain.

[0006] The links constituting the anchor chain may all have the same length, but preferably long links and short links are connected alternately so that the brackets are connected to the long links. The long links make it possible to increase the distance between the short links, thereby increasing the mounting location of the bracket, increasing the mounting strength, and allowing a large capacity bucket to be firmly mounted.

[0007]

[Operation] Anchor chains have high tensile strength and can be suspended in series to a height of several hundred meters or more, and it is also necessary to use buckets to scoop up earth and sand from the seabed or deep underground and carry it out. This is possible.

[0008]

[Example] A vertically installed tower 1 has a sprocket 3 that is rotatably driven by a motor 2 via a chain transmission mechanism and is pivotally supported diagonally above the upper end, and an anchor chain is bent diagonally upward at the top. Splots 5 and 6 are used as guides, and a sprocket 7 is pivotally supported at the bottom. An endless anchor chain 4 guided by the sprockets 5 and 6 is stretched between the upper and lower sprockets 3 and 7, and the motor 2 It is now more circularly driven.

As shown in FIGS. 2 and 3, the anchor chain has a structure in which long links 8 and short links 9 are alternately connected, and a stud 10 with a flat surface is fixed to each long link 8. Corresponding long links 8 of the anchor chain 4 on both sides are connected at regular intervals of the anchor chain 4 by brackets 11 whose end plate portions are fixed to studs 10 with bolts 12. A bucket 13 is fixed to each bracket 11.

The present embodiment is constructed as described above, and when the sprocket 3 is rotationally driven by the motor 2, the anchor chain 4 is circulated in the direction of the arrow in FIG. bucket 13
After rising to the top of the tower, it changes direction and is turned downward by sprocket 3 to discharge the earth and sand.

[0011]

According to the bucket conveyor of the present invention, since the tensile strength of the chain is high, it is possible to transport objects such as earth and sand from, for example, the deep seabed or deep underground. Furthermore, by configuring the anchor chain with long links and short links and connecting the bucket to the long links, the capacity of the bucket can be increased and the strength of its attachment can be increased.
