Technical Field

The invention relates to the technical field of ships, in particular to a movable double-station stone conveying system for precise stone throwing operation in deep and shallow sea.

Background

The only ship type that can realize the accurate stone operation of throwing in deep sea at present is the falling pipe stone throwing ship type. The ship type can realize various precise stone throwing operations from shallow water to deep water.

The drop tube riprap boat is generally provided with a large stone cabin and a riprap operation system, wherein the riprap operation system generally comprises an excavator, a conveying belt, a riprap tower, a special underwater robot for riprap and the like. The operation mode is as follows: a large number of rock falling pipe sections are stored in the rock throwing tower, the rock falling pipe sections are lengthened to the position above a seabed operation position in sections, a special underwater robot for stone throwing is arranged at the tail end of the pipeline and can be matched with a dynamic positioning system of a ship to realize accurate positioning of a rock throwing pipe head, stones in the stone material cabin are conveyed to a conveying belt through an excavator and then conveyed to the rock falling pipe, and therefore the rock falling pipe is thrown to a designated position on the seabed to realize accurate stone throwing operation.

At present, the mainstream riprap boat generally adopts a single-station operation mode of middle moon pool riprap or side riprap. The conveyor belt therefore usually takes the form of a fixed conveyor belt for single-station feeding.

The fixed conveyer belt is suitable for single-station stone throwing operation. At present, no stone throwing boat for double-station operation of a moon pool and a side is available. If a fixed conveying belt mode is adopted, 2 sets of fixed conveying systems are required to be arranged on the ship to respectively supply materials for double stations. Such an approach has the following disadvantages:

1) the number of conveying devices is greatly increased, and further configuration cost and maintenance cost are increased. And meanwhile, the utilization rate of the equipment is low.

2) The stone throwing boat has the advantages that various facilities such as large stone cabins and stone throwing towers are arranged on the deck of the stone throwing boat, the utilization rate of the deck is high, the area of the deck is very precious, the conveying system generally needs to be arranged on the deck surface, and the design mode enables the conveying system to occupy too much area of the deck, so that the overall arrangement is very unfavorable.

3) In order to realize double-station feeding, the conveying belt must reach the joint pipe positions of the stone throwing tower, namely the middle moon pool and the side, and in order to realize the operation function, the stone throwing tower is also necessarily positioned at the two positions during operation and needs to slide between the two stations, so that the collision with the arrangement position and the movement path of the stone throwing tower is likely to occur, the position of the stone throwing tower is likely to move upwards, the integral gravity center of a ship is improved, and the stability is very unfavorable.

The end of the fixed longitudinal conveyor belt 20 in the region of the moon pool is higher than the end of the stone compartment.

The fixed longitudinal conveyor belts 20 are distributed longitudinally along the vessel. The movable telescopic conveyor belts 30 are distributed transversely along the vessel. In a ship, the bow to stern direction is the longitudinal direction, and the port to starboard direction is the transverse direction.

In this embodiment, the movable telescopic conveyor belt 30 and the second movable material conveying hopper 32 are located between the moon pool and the starboard; the fixed longitudinal conveyor belt 20 and the first movable transport bin 31 are located between the moon pool and the port side.

In further implementations, the movable telescopic conveyor belt and the second movable material conveying hopper are located between the moon pool and the port; the fixed longitudinal conveyor belt and the first movable material conveying hopper are positioned between the moon pool and the starboard.

The movable double-station precise riprap operation stone conveying system has two operation states, namely a moon pool station operation state and a side station operation state.

In the operating state of the moonpool station, as shown in fig. 1, a rock dropping tower (not shown in the figure) in the moonpool is firstly connected with a rock dropping pipe, after the rock dropping pipe in the moonpool is connected with the rock dropping tower, the first movable material conveying hopper moves towards the moonpool until the first movable material conveying hopper is positioned below a rock outlet end of the fixed longitudinal conveyor belt, and a discharge port of the first movable material conveying hopper is aligned with the rock dropping pipe; the first movable material conveying hopper is locked at the position; the stone is conveyed from the stone cabin to the first movable conveying hopper through the fixed longitudinal conveying belt and then enters the stone falling pipe, so that the stone falling pipe is supplied with materials, and stone throwing is completed.

When the station operation state of the moon pool is in the working state, the telescopic section of the movable telescopic conveyer belt retracts to the upper part of the non-telescopic section, and the movable telescopic conveyer belt and the second movable conveying hopper are both positioned on the other side of the moon pool.

In the operation state of the side station, as shown in fig. 2 and 3, a rock dropping pipe is firstly connected to a rock throwing tower (not shown in the figures) on the side, and after the rock dropping pipe on the side is connected, the first movable material conveying hopper moves towards the direction away from the moon pool and leaves the position of a rock outlet end of the fixed longitudinal conveying belt; the telescopic section of the movable telescopic conveyer belt extends out towards the fixed longitudinal conveyer belt, crosses over the moon pool, is connected with the stone outlet end of the fixed longitudinal conveyer belt and is locked at the position; the second movable material conveying hopper moves towards the side working station until the discharge hole of the second movable material conveying hopper is aligned with the rock falling pipe, and then the second movable material conveying hopper is locked at the position; the building stones are conveyed from the building stones cabin through the fixed type longitudinal conveying belt and the movable telescopic conveying belt, then conveyed into the second movable conveying hopper, and then enter the stone falling pipe, so that the stone falling pipe is supplied with materials, and stone throwing is completed.

After the operation of the side station is completed, as shown in fig. 4, the telescopic section of the movable telescopic conveyor belt retracts to the position above the non-telescopic section, and the movable telescopic conveyor belt and the second movable material conveying hopper both move and are locked at the storage position between the moon pool and the side.

According to the invention, double-station stone throwing operation feeding and feeding switching operation of the middle moon pool and the side can be realized on one ship; and a mode of combining a fixed conveying belt and a movable conveying belt is adopted to realize double-station feeding.

The stone conveying system is used as a key component in a stone throwing system of the stone throwing boat, and a movable combined design form is adopted to realize stone supply of the stone throwing tower during operation at different stations, so that the realization of the operation functions of the moon pool and the shipboard double stations is ensured, and the applicability and the competitiveness of the falling pipe stone throwing boat type are improved.

The invention can realize the stone throwing operation of the moon pool station and the stone throwing operation of the shipboard station, can realize the consideration and the coverage of different water depths and operation types, and realizes the improvement of the stone throwing operation capability.
