Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier for bulk material, which is an amorphous solid cargo. The present invention relates to a bulk carrier equipped with cargo handling equipment.

[0002]

2. Description of the Related Art A bulk carrier for transporting bulk solids such as ores, coal, limestone, wood chips, grains, cement, and other irregular solid cargoes consisting of particles, powder, and the like is mainly used in sea transport. Those navigating along coastal areas often have to unload and dock at piers with incomplete cargo handling facilities.

For this purpose, Japanese Unexamined Utility Model Publication No. 2-333196 discloses that a bulk carrier is equipped with an automatic cargo handling facility for unloading bulk materials in a hold to the land, which is in practical use. .

[0004] That is, the automatic cargo handling equipment of a bulk carrier presented in the above-mentioned gazette and currently being implemented is characterized in that the bottom of the long hold in the longitudinal direction of the hull is formed by a hopper-shaped inclined portion and a flat portion at its lowest point. A payout machine and a vertical feed conveyor are arranged above and below a discharge port provided in the center of the flat portion over the entire length of the hold, and further extend from the end of the vertical feed conveyor to above the upper deck. It has a vertical conveyor and a boom with a conveyor that can rotate above the upper deck.

[0005] The dispensing machine has a wheel that rotates along the surface of the flat portion, and rotates the wheel while traveling in the longitudinal direction above the discharge port to remove the bulk material in the hold from the lowermost layer. From the outlet and drop onto the vertical conveyor from the discharge port. The dropped bulk material is sent from the end of the vertical feed conveyor to the upper deck by the vertical conveyor, and is then thrown by the boom conveyor into a receiving hopper for transfer to a conveyor or the like installed on the pier.

[0006]

According to the above-mentioned automatic cargo handling equipment, the bottom of the hold is a hopper type, and since the bulk is scraped off at its lowest position, it can be discharged without leaving it and landed. There is an advantage that there is no problem in terms of labor and health because there is no need for an operator to enter the area, and there is almost no scattering of dust generated from loose materials, so that the surrounding environment is not adversely affected.

However, since the bottom of the hold is hopper-shaped and the vertical feed conveyor is installed below the lowest point, a considerably large space exists below the hold, so that the ship has a relatively large space. In addition to the inevitable decrease in the capacity of the hold, a tunnel is installed in the hold that allows the dispensing machine to travel without being buried in bulk, which reduces the effective capacity of the hold and reduces the loading capacity. There was a problem.

In addition, since the dispensing machine and the vertical feed conveyor are installed near the bottom of the ship, maintenance and inspection are troublesome. In particular, when the dispensing machine stops due to biting loose materials or when a failure occurs. Restoration was very cumbersome and unloading had to be interrupted for a long time.

The present invention has a problem that a bulk carrier having an automatic cargo handling facility having the above-mentioned structure has a small loading capacity, and in addition to this, maintenance and inspection are troublesome and repair in the event of trouble is troublesome. The purpose of the present invention is to provide an automatic cargo handling facility that can increase the loading capacity, can easily perform maintenance, inspection, repair, etc., and can smoothly discharge the cargo. And

[0010]

That is, in the present invention, a hold having a hatch on the upper deck is provided from near the bow to near the stern, and the bridge is arranged on either the bow side or the stern side. For bulk carriers, scraping means for removing bulk material from the hold above the hatch, inboard conveyor means for sending the bulk material to one location on the bow or stern side, and bulk material sent to one location An automatic loading and unloading facility having an outboard conveyor and means for transporting goods to a predetermined location on the wharf was provided.

The scraping means includes a traveling body that reciprocates over the hatch over substantially the entire length thereof, a bucket conveyor that is mounted on the traveling body and has a lower part that can be raised and lowered, and that is moved into and out of the hold from the hatch. A supply chute is provided on the traveling main body and guides loose materials sent out from the bucket conveyor to one side of the hatch of the upper deck.

The above-mentioned in-vehicle conveyor means includes a vertical conveyor provided in a side clearance between the hull and the hold, and a vertical feeder provided substantially over the entire traveling section of the traveling main body to directly feed bulk materials from a supply chute. And a guiding conveyor for dropping onto the conveyor, and a lifting conveyor for sending the bulk material sent out from the vertical conveyor to the upper deck.

Further, the above-mentioned outboard conveyor means includes a boom which is cantileverably mounted on the upper deck and a land which is provided along the boom and which sends bulk materials delivered from the lifting conveyor to the boom tip. And a lifting conveyor.

In the automatic cargo handling equipment of the present invention, a bucket conveyor is inserted into a hold from a hatch to scrape loose objects, and a supply chute, a guide passage, a vertical conveyor, a lifting conveyor, and a landing conveyor are used. It is sent to a predetermined location on the wharf.

Since the lower part of the bucket conveyor can be raised and lowered, it is easy to put it in and out of the hold. In addition, by changing the position of the lower part, ie, the scraping portion, and moving the traveling body, the bucket conveyor can be unloaded without leaving any bulk material. be able to.

In particular, by adopting a configuration in which bulk materials are scraped from above and a vertical conveyor is disposed outside the hold, the bottom of the hold can be made closer to the bottom of the ship and the bottom can be made flat to increase the effective volume. And each conveyor is not located near the bottom of the ship, so maintenance, inspection, repair, etc. are easy,
Even if the operation is interrupted due to trouble, it can be repaired in a short time.

Next, if the bucket conveyor is made reciprocable in the hatch transverse direction and a transfer conveyor for sending the bulk material sent out from the hatch to the supply chute is provided, a large hold width can be obtained. However, it is possible to scrape loose objects continuously.

In particular, a first scraping portion at the tip of the bucket conveyor which is maintained in a horizontal state, a second scraping portion in which the inclination angle can be arbitrarily changed between a vertical state and a horizontal state, a vertical state If the first and second scraping portions are configured to be located higher than the hatch when the first and second scraping portions are in a horizontal state, the posture is changed in accordance with the loading state of bulk materials. Efficient scraping can be performed, the bottom can be dredged, landing can be performed with almost no residue, and the hatch can be easily taken in and out and evacuated to the outside of the hatch.

In this case, by setting the first and second scraping portions in the horizontal state to a height position which does not interfere with the winder of the hatch cover installed on the upper deck, the hatch is moved outward from the hatch when not operating. Evacuation becomes easier.

Here, the storage space for the scraping means is provided along the back and one side of the bridge so that the traveling body is located between the hatch and the bridge and the bucket conveyor is located on one side of the bridge. In this case, the ship can sail without obstructing the view from the bridge.

Further, the upper end entrance of the guide passage of the inboard conveyor means may be closed with a hatch cover, or the portion of the lifting conveyor that protrudes upward from the upper deck and the landing conveyor may be covered with a covering structure. If you have a configuration,
There is no concern that each conveyor will be flooded or the equipment will rust due to rainwater or waves during navigation. Further, since each conveyor is shielded from the atmosphere, there is a dustproof effect.

Further, when the lifting conveyor is configured to enclose and transport loose objects with two endless belts facing each other, the loose objects can be transported upward without spilling, and can be inclined in the lateral direction of the hull. As a result, it is possible to effectively utilize the narrow space in the hull for installation.

[0023]

1 and 2 schematically show an embodiment of the present invention. In FIG. 1 and FIG. 2, a hold 2 extending in the longitudinal direction of the hull from near the bow to near the stern is provided inside a hull 1 at an intermediate position. The hold 2 is open and closed by a hatch 4 provided on an upper deck 5. In addition, the partition wall 3 of the hold 2
Winders 7a, 7b for hatch covers 6a, 6b for opening and closing the bow-side half and the stern-side half respectively defined by
Are placed on the upper deck 5 close to the front and rear ends of the hold 2. Further, a bridge 8 is provided further on the stern side than the winder 7b on the stern side.

In FIGS. 1 and 2, A is a scraping means, B
Denotes an inboard conveyor means, and C denotes an outboard conveyor means, and an inboard conveyor means B extending in the vertical direction of the hull while the scraping means A moves in the vertical direction of the hull while moving the bulk material scraped out of the hold 2 near the bow. It is sent to the installed outboard conveyor means C, and is discharged to a predetermined place on the pier.

Referring mainly to FIGS. 3, 4 and 5, the scraping means A is mounted on the traveling rail 11 which is positioned on both sides of the hold 2 and is laid on the upper deck 5 in the longitudinal direction of the hull. Gate-shaped traveling body 12 that reciprocates over substantially the entire length of
And a bucket conveyor 15 mounted in a suspended state on a carriage 14 reciprocatingly traveling on a guide rail 13 laid on the traveling main body 12 and extending in the lateral direction of the hull, that is, in the transverse direction of the hatch.
And a transfer conveyor 20 comprising a belt conveyor extending in the hatch transverse direction and provided on the traveling body 12, and a supply chute 21 extending downward.

The bucket conveyor 15 is a well-known conveyor in which a number of buckets are laid at fixed intervals on two mutually parallel endless chains. 16b, guide rail 16c,
A tip-reversing chain wheel 16d supported at the tip of the first arm member 17a of the first arm member 17a and the second arm member 17b rotatably connected to each other, a first bent wheel wheel 16e provided at a connection point of these, An endless chain is hooked on a second bent chain wheel 16f provided at a position where the base end of the two-arm member 17b is rotatably connected to the carriage 14, and travels in a counterclockwise direction in FIGS. Let me do. An elastic member 18 is provided at the center of each of the two arm members 17a and 17b.
The base end of the cylinder and the tip of the piston rod of the fluid pressure cylinder are connected to each other.

The bucket conveyor 15 has a tip inverted chain wheel 16
d and a first scraping portion 1 that is kept horizontal between the first bent sprocket 16e and mainly scrapes loose objects on a horizontal plane.
5a, the first bent wheel 16e and the second bent wheel 16e
f, a second scraping portion 15b is formed, the inclination angle of which is arbitrarily variable between the vertical state and the horizontal state, and which mainly scrapes loose objects on the inclined surface. A carry-out portion 15c extending upward in a vertical state is formed between the second bent chain wheel 16f and the terminal reversing wheel 16a.
When the bucket faces downward during the travel from the to the guide sheave 16b, loose objects fall from the bucket conveyor 15 and are sent out.

FIGS. 4 and 5B show a state in which the expansion and contraction member 18 is in a substantially middle extension state, and the second scraping portion 15b has an inclination angle of about 45 degrees. The loose material is scraped off by the two scraping portions 15a and 15b. The bulk loaded in hold 2 is the second scraping part 1
5b is substantially horizontal, and the scraping is started by gradually inclining it, and by continuously adding the operation of reciprocating the traveling main body 12 in the hull longitudinal direction and the operation of reciprocating the bogie 14 in the hull lateral direction as needed, to continuously separate loose objects. Perform a scraping operation.

As the bulk of the hold 2 decreases, the inclination angle of the second scraping portion 15b is increased, and finally the vertical state as shown in FIG. 5 (C) through the state of FIG. 5 (B). . At this time, the length of the second arm member 17b and the height position of the second bent chain wheel 16f are set such that the bucket of the first scraping portion 15a substantially contacts the bottom wall 2a of the hold 2. Thereby, the bottom of the hold 2 can be dredged.

Since the endless chain of the bucket conveyor 15 and the sheaves 16d and 16e which are put into and taken out of the hold 2 are arranged on both outer sides of the bucket, the bucket is connected to the side wall 2b and the bottom wall 2a of the hold 2. I can't hit the corner and I can't scrape the bulk of this part. Therefore, in the illustrated embodiment, the portion of the bucket shown in FIG. 3 outside the hull lateral movement limit 15A is defined as the inclined wall 2c, and loose objects fall into the bucket traveling area and are scraped out with almost no residue. Was made possible. Since the inclined wall 2c has a slight height, the decrease in the volume of the hold 2 can be ignored.

The second bent sprocket 16f is also provided with the second arm member 1
When the traveling main body 12 and the bucket conveyor 15 are placed in the storage space 10 described later with the traveling body 7b in a horizontal state, a height that does not collide with the winder 7b. It is installed at a height position that does not collide with the winding shaft of the take-up machine 7b. Therefore, when the hatch 4 is opened for loading and unloading, the bucket conveyor 15 is moved above the hatch 4 so as not to hinder the winding of the hatch cover 6b onto the winder 7b. When the hatch 4 is closed after loading, the traveling body 12 and the bucket conveyor 15 are stored in the storage space 1.
Move to zero.

When unloading, open the hatch 4
5A, the second arm member 1 is positioned above
From the position where 7b is in the horizontal state, the guide rail 16c of the bucket conveyor 15 and the portion on the tip side from the second bent chain wheel 16f are pivoted down, and the bulk of the hold 2 is scraped from the surface layer by the bucket. .

In the position shown in FIG. 5 (A), the expansion and contraction member 18 is in a substantially maximum extended state, and the two arm members 17 are extended.
The opening angles of a and 17b are close to 180 degrees.
The tip reversing chain wheel 16d is located farthest from the second bent wheel wheel 16f and is located above the lowermost end of the arc-shaped guide rail 15c, and pulls the endless chain of the bucket conveyor 15. For this reason, the endless chain contacts almost the entire length of the guide rail 16c and meshes with the second bent wheel 16f in a phase range of 90 degrees, so that the portion between these portions of the bucket conveyor 15 is not rotated down by its own weight.

When the telescopic member 18 is contracted, the opening angle of the two arm members 17a and 17b becomes small,
6d comes closer to the second bending wheel 16f. As a result, the endless chain is maintained in a tensioned state while gradually moving away from the exit end side of the guide rail 16c, and the bucket conveyor 1 is maintained.
The lower end portion between the guide rail 16c and the second bent chain wheel 16f, that is, the lower portion is rotated down by its own weight.

As a result, the second scraping portion 15b along the second arm member 17b moves from the horizontal state shown in FIG. 5A to the vertical state shown in FIG. Leads to. On the other hand, the first arm member 17a
7b is rotatably connected to the tip of the extension 7b.
Is connected to the center of the second arm member 17 by
Accordingly, the first scraping portion 15a can be kept horizontal regardless of the inclination angle of the second scraping portion 15b.

When the scraping is completed, the elastic member 1
8, the two arm members 17a, 17b
FIG. 5
The state returns to (A). Thus, the bucket conveyor 1
5 can be moved up and down from above the hatch 4 by making the lower part of the hatch 4 undulating. In addition, the lower part is further bent by two scraping portions 15a and 15b.
According to the illustrated embodiment, it is possible to scrape out almost no bulky material.

The bulk material scraped by the bucket and conveyed upward is supplied to the end reversing chain wheel 16 at the top end of the bucket conveyor.
When it is reversed along a, it is discharged from the bucket, falls through the chute 19 onto the transfer conveyor 20, and is sent toward one end of the traveling body 12. The reversal point of the conveyor 20 is set at the upper end of the supply chute 21, and the scraps scraped while the bucket conveyor 15 moves in the vertical and horizontal directions of the hull are thrown into the supply chute 21.

A suction port of a dust collector 22 installed on the traveling body 12 is opened at a lower end of the supply chute 21 so that dust generated from falling bulk materials is prevented from scattering around. The truck 14 is composed of the guide rail 16c of the bucket conveyor 15, the second bent chain wheel 16f.
And a housing 23 surrounding the transfer conveyor 20 so as to minimize the scattering of dust.

Further, an upper deck portion between the hatch 4 and the bridge 8 and on one side of the bridge 8 forms a storage space 10 for the scraping means A, and the hatch 4 is provided with hatch covers 6a and 6a.
When the vehicle is not being loaded or unloaded, the traveling main body 12 is positioned between the hatch 4 and the bridge 8 and the two scraping portions 1 of the bucket conveyor 15 are covered.
5 a and 15 b are located on the side of the bridge 8.

As described above, by disposing the scraping means A mounted on the deck 5 along the rear surface and one side surface of the bridge 8, the view from the bridge 8 is not obstructed during navigation. Further, a wall or a roof may be provided on one side of the bridge of the storage space 10 to insert the two scraping portions 15a and 15b which are in a horizontal state, thereby protecting them from waves and rainwater.

Incidentally, it is preferable that the scraping means A housed in the storage space 10 be fixed to the structural portion or the outfitting portion of the hull 1 with a steel cable, a chain or the like so as not to run away due to the shaking of the hull 1. . However, if the traveling main body 12 is provided with a clamp and is fixed by grasping the traveling rail 11 using electromagnetic force or fluid pressure, the scraping means A can be automatically and instantaneously fixed and released, and labor can be performed. In addition to being reduced, it can be fixed at an arbitrary location above the hatch 4 and the scraping at that location can be performed stably.

Next, the inboard conveyor means B is shown in FIGS.

The vertical conveyor 27 extends from near the stern end of the hold 2 to the front of the bow end face, and the lower end outlet of the supply chute 21 approaches the upper end inlet of the guide passage 28. For this reason, the scraps scraped out of the hold 2 while the scraping means A moves in the vertical direction of the hull are sent to the guide passage 28 regardless of the position of the scraping means A, and the conveyor for vertical feeding is directly held without stagnation. 27 can be dropped.

The entrance at the upper end of the guide passage 28 may be opened to the outside of the hatch 4. However, when it is opened to the inside of the hatch 4 as in the illustrated embodiment, the hatch cover 6a,
The hatch 4 can be opened and closed simultaneously without changing the width of 6b. By covering the upper end entrance of the guide passage 27 with the hatch covers 6a and 6b, the vertical conveyor 27 is installed below the upper deck 5, and the water is immersed in waves and rainwater, and the equipment parts are removed. This eliminates concerns about rust and breakdown.

The lifting conveyor 29 has the same configuration as a well-known vertical belt conveyor that conveys bulk materials from a low place to a high place in a sealed state with two endless belts 29a and 29b facing each other. In the illustrated embodiment, the hull 1 is installed in the gap between the hull 1 and the hold 2 on the bow side so as to be inclined in the lateral direction of the hull.
That is, the low-end feed end is located orthogonally below and below the discharge end of the vertical conveyor 27, and the high-end send end is positioned above the upper deck 5 on the side opposite to the hull in the lateral direction. I have.

As described above, by using the narrow space in the hull 1 and installing the hull in the horizontal direction, the length of the conveyor is shortened as compared with the configuration having a horizontal portion and a vertical portion. , And can efficiently convey the bulk material without fear of leaking. This lifting conveyor 29
Receives the bulk material sent from the vertical conveyor 27 at the feeding end on one belt 29a, then faces the other belt 29b, and overlaps and closes both side edges of the bulk material to remove the bulk material. It is sealed and conveyed to a height according to an inclined conveyance path, and is delivered at a belt reversal point or delivery end at a height.

The portion of the lifting conveyor 29 projecting upward from the upper deck 5 is incorporated in a housing 30 provided on the upper deck 5 to protect it from waves and rainwater, and these enter the hull 1. Not to be.

A fluid pressure cylinder 35 for raising and lowering the boom 33 between a horizontal state and an upright state is provided.

The delivery end of the landing conveyor 34 is located below the delivery end of the lifting conveyor 29, and the bulk material delivered from the lifting conveyor 29 passes through the chute 36 for landing. The landing is completed by dropping to the feed end of the conveyor 34 and then dropping from the output end of the boom 33 to a predetermined location on the pier.

The boom 33 has a housing 37 surrounding the landing conveyor 34. This housing 3
Reference numeral 7 functions as a covering structure for protecting the landing conveyor 34 from waves and rainwater, similarly to the housing 30 surrounding the upper deck of the lifting conveyor 29 provided outside the hull.

It should be noted that the boom 33 is stored above the upper deck 5 along the side of the ship and can be turned so as to protrude toward the wharf at the time of unloading. The ability to undulate to accommodate height variations relative to the wharf is the same as in the prior art.

The transfer conveyor 20, the vertical conveyor 27, and the landing conveyor 34 are not limited to the belt conveyor, but may be a slat conveyor, a screw conveyor, or the like.
