Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a movable double-station stone conveying system for deep- and shallow-sea precise riprap operations. Background Art

[0002] At present, the only vessel type that can realize the deep-sea precise riprap operation is the drop tube riprap vessel type, which can realize various precise riprap operations from shallow water to deep water.

[0003] The pipe-dropping ship is generally equipped with a large stone tank and a stone dumping operation system. The stone dumping operation system usually includes excavators, conveyor belts, stone dumping towers, underwater robots for stone dumping and other equipment. Its operation method is: a large number of rock dumping pipe sections are stored in the stone dumping tower, and the rock dumping pipe sections are extended one by one to the top of the seabed operation position. The end of the pipeline is equipped with a special underwater robot for stone dumping, which can cooperate with the ship's own dynamic positioning system to achieve precise positioning of the stone dumping pipe head. The stones in the stone tank are transported to the conveyor belt by the excavator and then to the rock dumping pipe, and then thrown to the designated position on the seabed through the rock dumping pipe to achieve precise stone dumping operation.

[0004] At present, the mainstream riprap ship generally adopts the single-station operation mode of riprap in the middle moon pool or riprap on the side. Therefore, the conveyor belt usually adopts the form of a fixed conveyor belt to realize the single-station feeding.

[0005] This type of fixed conveyor belt is suitable for single-station riprap operations. Currently, there is no riprap ship that can operate at both the moon pool and the side. If the fixed conveyor belt method is used, two fixed conveying systems need to be arranged on the ship to feed the two stations. This method has the following disadvantages:

[0006] 1) The number of conveying equipment is greatly increased, which in turn increases the configuration cost and maintenance cost. At the same time, the equipment utilization rate is low.

[0007] 2) The deck of the riprap ship is equipped with a variety of facilities such as large stone cabins and riprap towers. The deck utilization rate is very high and the deck area is very precious. The conveying system generally needs to be arranged on the deck surface. This design method will cause the conveying system to occupy too much deck area, which is very unfavorable to the overall layout.

[0008] 3) In order to realize double-station feeding, the conveyor belt must reach the riprap take-over position, that is, the middle moon pool and the side. In order to realize the operation function, the riprap must also be located at these two positions during operation and needs to slide between the two stations. Therefore, it is very likely to conflict with the layout position and movement path of the riprap, which is likely to cause the position of the riprap to move up, thereby increasing the overall center of gravity of the ship, which is very unfavorable to stability. Summary of the invention

[0009] The technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a movable double-station stone conveying system for deep and shallow sea precise riprap operations.

[0010] The present invention solves the above technical problems through the following technical solutions:

[0032] The second movable hopper 32 has a second power component 42 for driving the second movable hopper to move toward a direction approaching the moon pool or toward a direction away from the moon pool.

[0033] In this embodiment, the second power component 42 includes a second motor 52 and a second rotating wheel 62 driven by the second motor.

[0034] The movable telescopic conveyor belt 30 has a third power component 43 for driving the movable telescopic conveyor belt to move toward a direction approaching the moon pool or toward a direction away from the moon pool.

[0035] In this embodiment, the third power component 43 includes a third motor 53 and a third rotating wheel 63 driven by the third motor.

[0036] The movable telescopic conveyor belt 30 also has a telescopic section 40 which can extend across the moon pool to the fixed longitudinal conveyor belt to receive stones and can be retracted to the other side of the moon pool.

[0037] The movable telescopic conveyor belt 30 further includes a non-telescopic section 50 ; the telescopic section 40 is arranged above the non-telescopic section 50 .

[0038] exist Figure 1 , Figure 2 , Figure 3 and Figure 4 In order to clearly distinguish the telescopic section 40 from the non-telescopic section 50, the telescopic section 40 is indicated by a dotted line. It should be noted that the dotted line does not mean that the component is invisible.

[0039] The end of the fixed longitudinal conveyor belt 20 located in the area where the moon pool is located is higher than the end located in the stone cabin.

[0040] The fixed longitudinal conveyor belt 20 is distributed along the longitudinal direction of the ship. The movable telescopic conveyor belt 30 is distributed along the transverse direction of the ship. In the ship, the direction from the bow to the stern is the longitudinal direction, and the direction from the port side to the starboard side is the transverse direction.

[0041] In the present embodiment, there are two stone bunkers, namely the front stone bunker 12 and the rear stone bunker 13; the moon pool 11 is arranged between the front stone bunker 12 and the rear stone bunker 13, and there are two fixed longitudinal conveyor belts 20, one of which extends from the front stone bunker to the area where the moon pool is located, and the other fixed longitudinal conveyor belt extends from the rear stone bunker to the area where the moon pool is located.

[0042] In this embodiment, the movable telescopic conveyor belt 30 and the second movable feed hopper 32 are located between the moon pool and the starboard side; the fixed longitudinal conveyor belt 20 and the first movable feed hopper 31 are located between the moon pool and the port side.

[0043] In another embodiment, the movable telescopic conveyor belt and the second movable hopper are located between the moon pool and the port side; the fixed longitudinal conveyor belt and the first movable hopper are located between the moon pool and the starboard side.

[0044] The movable dual-station stone conveying system for deep- and shallow-sea precise riprap operations of this embodiment has two operating states, namely, a moon pool station operating state and a side station operating state.

[0045] Moon pool station operation status, such as Figure 1 As shown, the rock-dropping tower (not shown in the figure) located in the moon pool is first connected to the rock-dropping pipe. After the rock-dropping pipe in the moon pool is connected, the first movable hopper moves toward the moon pool until it is located below the stone outlet end of the fixed longitudinal conveyor belt, and the discharge port of the first movable hopper is aligned with the rock-dropping pipe; the first movable hopper is locked in this position; the stone is transported from the stone cabin through the fixed longitudinal conveyor belt to the first movable hopper, and then enters the rock-dropping pipe, so that the rock-dropping pipe is fed and the rock-dropping is completed.

[0046] When the moon pool station is in operation, the telescopic section of the movable telescopic conveyor belt is retracted above the non-retractable section, and the movable telescopic conveyor belt and the second movable feed hopper are both located on the other side of the moon pool.

[0047] Working status of side station, such as Figure 2 and Figure 3As shown, the rock dumping tower (not shown in the figure) located on the side is first connected to the rock drop pipe. After the rock drop pipe on the side is connected, the first movable feed hopper moves in the direction of leaving the moon pool and leaves the position of the stone outlet end of the fixed longitudinal conveyor belt; the telescopic section of the movable telescopic conveyor belt extends in the direction of the fixed longitudinal conveyor belt, the telescopic section of the movable telescopic conveyor belt crosses the moon pool, and connects with the stone outlet end of the fixed longitudinal conveyor belt, and then is locked at this position; the second movable feed hopper moves in the direction of the side working station until the discharge port of the second movable feed hopper is aligned with the rock drop pipe, and then is locked at this position; the stone is transported from the stone cabin through the fixed longitudinal conveyor belt and passes through the movable telescopic conveyor belt, and then is transported to the second movable feed hopper, and then enters the rock drop pipe, so that the rock drop pipe is fed and the rock dumping is completed.

[0048] After the side station work is completed, Figure 4 As shown, the telescopic section of the movable telescopic conveyor belt is retracted to the top of the non-retractable section, and the movable telescopic conveyor belt and the second movable feed hopper are both moved and locked in the storage position between the moon pool and the side.

[0049] The present invention can realize the riprap operation feeding and feeding switching operation of the middle moon pool and the side double workstations on one ship; the double workstation feeding is realized by combining a fixed conveyor belt and a movable conveyor belt.

[0050] The stone conveying system of the present invention, as a key component of the riprap system of the riprap ship, adopts a movable modular design to realize the stone supply when the riprap tower is operating at different workstations, thereby ensuring the realization of the moon pool and the side double-workstation operation functions, and improving the applicability and competitiveness of the drop-tube riprap ship type.

[0051] The present invention can realize the stone throwing operation at the moon pool work station and the stone throwing operation at the side work station, can take into account and cover different water depths and operation types, and realize the improvement of the stone throwing operation capacity.

[0052] Compared with two sets of fixed conveyor belts, the present invention saves configuration cost and maintenance cost, improves the utilization rate of the conveyor belt, and greatly reduces the occupied area of ​​the deck, which is very beneficial to the overall layout.

[0053] In the present invention, the movable arrangement of the conveyor belt and the overlapping storage method greatly increase the flexibility of the arrangement, provide more adjustable space for the arrangement and sliding movement of the riprap tower, reduce the arrangement pressure of the riprap tower, and the riprap tower does not need to be raised, which is very beneficial to lowering the center of gravity of the ship.

[0054] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
