Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of salvage ships, in particular to an amphibious ship for salvaging large floating objects. BACKGROUND

[0002] Large floating objects can appear in the open sea, intertidal zone shoals, reefs and the like. In order to successfully salvage large floating objects in the above-mentioned areas, an amphibious ship for salvaging large floating objects is usually used to salvage large floating objects.

[0003] Chinese Patent Publication No. CN207374616U discloses a large floating object offshore recovery equipment, which comprises a salvage ship, a telescopic crane, a large floating object seat frame, and front and rear tensioning devices. The telescopic crane extends to the side and can rotate, and the large floating object seat frame is located within the radius of the telescopic crane. A salvage intercepting arm, an oil cylinder, and an inclination sensor are provided on the telescopic crane. The control center controls the extension and retraction of the oil cylinder according to the inclination parameter of the inclination sensor, thereby compensating for the levelness of the salvage intercepting arm according to the rolling of the ship body. A roll-prevention device is connected to the lower part of the salvage intercepting arm, and a net is connected to the lower part of the salvage intercepting arm. The passive compensation device is composed of a compensation oil cylinder, an accumulator, and a gas bottle group, which effectively reduces the impact of the ship's deep draft on the trawl net and improves the net type. The compensation device consumes less energy. The external control hydraulic oil opens the rotary brake device, making the intercepting arm in a relative floating state in the horizontal direction, greatly improving the stress state of the intercepting arm in adverse sea conditions.

[0004] Traditional salvage ships usually use a single propeller propulsion method, which is not convenient for shallow water areas and complex terrain, limiting the salvage range.

[0005] Traditional salvage ships have a single salvage structure, such as the trawl net used in the above-mentioned case to salvage large floating objects. Since the trawl net is made of soft material, it is easy to cause the large floating object to tilt after lifting it upward, thereby causing safety problems for the personnel inside the large floating object. In addition, since the large floating object has a certain weight, it is easy to fall during the lifting process.

[0006] Secondly, the traditional salvage method blocks the side door and the top door of the large floating object, affecting the personnel inside the cabin. SUMMARY

[0007] The present application aims to at least solve the single fishing structure of the traditional fishing vessel in the prior art, such as the fishing of large floating objects by using the trawl in the above case, since the trawl is soft, the large floating object is easily tilted after being lifted upward, thereby causing the safety problem of the staff in the large floating object, and since the large floating object has a certain weight, the large floating object is easily dropped during the lifting process, secondly, the traditional fishing method blocks the side door and the top door of the large floating object, thereby affecting the egress of the staff in the cabin, therefore, the present application provides an amphibious ship for fishing large floating objects.

[0013] Further, the hook is suspended with a radial hook.

[0014] Further, the middle and rear portions of the two pieces of body are connected as a whole by a connecting bridge, an egress frame is arranged in front of the leading edge of the connecting bridge, and the two side legs of the egress frame are arranged on the decks of the two pieces of body.

[0015] Further, the egress frame is located at the rear side of the hoisting frame, and an egress opening is formed at the top of the egress frame.

[0016] Further, the two intercepting arms are opened and closed by two hydraulic push rods.

[0017] Further, the support arm is telescoped by two sets of hydraulic push rods provided by the seat driving moving mechanism, and the two sets of hydraulic push rods are symmetrically arranged at the lower portions of the two pieces of body.

[0060] As Figure 1 shown, a set of caterpillar walking device 2 is arranged at each of the front and rear parts of the outer side of each piece of body 1, and a full-rotation rudder 3 is arranged at the tail end of each piece of body 1; a contraction groove 14 is arranged at the tail end of the piece of body 1, a gas cylinder 15 is arranged in the contraction groove 14, and the gas cylinder 15 realizes the extension and contraction of the full-rotation rudder 3; when salvaging on the sea surface, the ship body is moved out of the land warehouse through the caterpillar walking device 2; when the ship body is driven to the intertidal shallow water area, the average draft has not reached the designed waterline, the ship body is subjected to considerable buoyancy, but the caterpillar walking device 2 is not completely separated from the ground, the gripping force of the caterpillar walking device 2 is weakened due to the buoyancy, which is not conducive to walking, at this time, sea water is injected into the ballast tank in the ship to appropriately offset part of the buoyancy, so as to ensure the gripping capacity of the caterpillar walking device 2, thereby facilitating walking; when the ship body continues to move forward to the deep water area, the caterpillar walking device 2 is completely separated from the ground under the action of the buoyancy, at this time, the sea water in the ballast tank is discharged, and the ship body propulsion system is switched from the caterpillar walking device 2 to the rudder propulsion device, that is, the gas cylinder 15 pushes the full-rotation rudder 3 out of the contraction groove 14, and the full-rotation rudder 3 drives the ship body to move forward.

[0061] As Figure 3 shown, the intercepting mechanism comprises two movable intercepting arms 10 arranged at the bow of the piece of body 1, a detection and feedback mechanism is arranged on the intercepting arm 10, the detection and feedback mechanism can adopt ultrasonic sensors, infrared sensors and laser radars to detect the obstacles in front, so as to prevent the intercepting arm 10 from colliding with the floating object, the two intercepting arms 10 are respectively opened and closed through two hydraulic push rods 11, in the above ship body moving process, the intercepting arm 10 is in a closed state, after the ship body sails to the working area, the large floating object floating on the sea surface is found, the intercepting arm 10 is opened, the two intercepting arms 10 are opened to the outside of the piece of body 1, at this time, the ship body continues to move forward to the large floating object, after the large floating object completely enters the line connecting the front ends of the two opened intercepting arms 10, the two intercepting arms 10 are gradually closed, at this time, the ship body slows down.

[0062] Specifically, as Figures 9-13 shown, it is the state of the amphibious ship for salvaging large floating objects approaching the target object to be salvaged.

[0063] As Figure 4 and Figure 8As shown, the righting mechanism includes support arms 16 between the two pieces 1, the support arms 16 for supporting the bottom of the fishing object, the support arms 16 through the seat driving mechanism provided with two sets of hydraulic push rod three 17 to achieve expansion, two sets of hydraulic push rod three 17 symmetrical distribution in the lower part of the two pieces 1 inside, and below the designed water line, the ship body drives to the appropriate area, so that the lifting frame 5 is located above the large floating object, at this time the support arms 16 under the action of hydraulic push rod three 17 stretch out, and hold the bottom of the large floating object, due to the two pieces 1 of the deck on the symmetrical installation of hydraulic push rod two 12, the piston end of the hydraulic push rod two 12 is provided with a detent rod 13, at the same time, the hydraulic push rod two 12 pushes the detent rod 13 to stretch out, the length of the detent rod 13 is controlled by the ship body operator, so as to realize the righting of the large floating object, under the expansion and contraction adjustment of the support arms 16 and the detent rod 13, the righting of the large floating object makes it face the lifting hook 8 of the lifting frame 5, and then the seat driving mechanism further includes hydraulic push rod four 19.

[0064] As shown in Figure 5 and Figure 7 , the lifting mechanism includes a lifting frame 5 across the two pieces 1, the lifting frame 5 top mounted with winch 6, the rope body wound by the winch 6 is connected with the sling 7, the lower end of the sling 7 is installed with the lifting hook 8, the lifting hook 8 is lowered, the radiation lifting claw 9 suspended under the lifting hook 8 is stretched out, each radiation lifting claw 9 holds one lifting ring on the top of the large floating object, then the detent rod 13 is retracted to the original position, the winch 6 is started, the large floating object rises with the lifting hook 8, and then the support arms 16 are retracted to the original position.

[0065] Specifically, as shown in Figures 14-18 , it is the lifting state of the amphibious ship after fishing the large floating object;

[0066] As shown in Figure 4 and Figure 8 , the seat mechanism includes a seat body 18, the seat body 18 is located on the upper side of the support arm 16, the support arm 16 slides on the bottom of the seat body 18, the seat body 18 is driven by the hydraulic push rod four 19, the hydraulic push rod four 19 is divided into the inside of the two pieces 1, the ejection rack 4 is located at the rear side of the lifting frame 5, at the same time of the retraction of the support arm 16, the seat body 18 is forwardly stretched to the directly below of the large floating object under the action of the hydraulic push rod four 19, holds and locks the large floating object, and then the radiation lifting claw 9 is unlocked from the lifting ring of the large floating object and is retracted, and then the hydraulic push rod four 19 retracts with the seat body 18, so that the large floating object is just brought to the directly below of the ejection rack 4 by the seat body 18.

[0067] And the ejection port 20 is opened on the top of the ejection rack 4, the personnel on the ship or stands in front of the connecting bridge deck to open the side door of the large floating object, or climbs on the ejection rack 4 to open the top door of the large floating object, so that the personnel can enter the ejection rack 4 from the ejection port 20.

[0068] Specifically, as shown in Figures 19-23 It is the amphibious ship for salvaging large floating objects in the state of completing the salvage target.

[0069] Example Two

[0070] Considering that large floating objects can fall in different sea areas, when salvaging in the intertidal shallow water area, since the large floating objects are mostly exposed to the water surface at this time and are in an upright state, the operation method is as follows:

[0071] The ship body is moved out of the land warehouse by the track walking device 2. When the ship body travels to the intertidal shallow water area and the average draft has not reached the designed waterline, the ship body is subjected to considerable buoyancy, but the track walking device 2 is not yet separated from the ground, and due to the action of the buoyancy, the gripping force of the track walking device 2 is weakened, which is not conducive to walking. At this time, sea water can be injected into the ballast tank in the ship to appropriately offset part of the buoyancy, so as to ensure the gripping ability of the track walking device 2 and facilitate walking.

[0072] During the above forward movement, the intercepting arms 10 are in a closed state. After the ship body sails to the working area and the large floating object in an upright state is found, the intercepting arms 10 are opened, and the two intercepting arms 10 are opened to the outside of the sheet body 1. At this time, the ship body continues to move forward to the large floating object. After the large floating object completely enters the line connecting the front ends of the two opened intercepting arms 10, the two intercepting arms 10 are gradually closed. At this time, the ship body slows down.

[0073] After the ship body travels to the appropriate area, so that the lifting frame 5 is located above the large floating object, the lifting hook 8 is lowered, the radiation lifting claws 9 suspended below the lifting hook 8 are extended, each radiation lifting claw 9 grabs a lifting ring at the top of the large floating object, and then the clamping rod 13 is retracted to the original position. The winch 6 is started, and the large floating object rises with the lifting hook 8.

[0074] The seat frame body 18 is extended straight under the large floating object under the action of the hydraulic push rod 19, supports the large floating object, and locks the large floating object. Then the radiation lifting claws 9 are unlocked from the lifting rings of the large floating object and are retracted. Next, the seat frame body 18 with the large floating object is retracted to the original position. At this time, the large floating object is just brought to the seat frame body 18 below the ejection rack 4. The personnel on the ship stand in front of the connecting bridge deck and open the side door of the large floating object, or climb onto the ejection rack 4 and open the top door of the large floating object for personnel to exit the cabin.

[0075] Example Three

[0076] When salvaging in the intertidal beach area, since the large floating object is in an upright state and is located in a waterless area, the operation method is as follows:

[0077] The ship body moves out of the land warehouse, at this time, the track walking device 2 pushes the ship body to move forward, compared with the wheel walking system, the track walking system has a large contact area with the beach and is not easy to sink into the sand. During the above movement, the intercepting arm 10 is in the closed state. When the ship body sails to the working area and a large floating object is found, the intercepting arm 10 is opened, and the two intercepting arms 10 open outwardly of the sheet body 1. At this time, the ship body continues to move forward to the large floating object. When the large floating object completely enters the front end connecting line of the two fully opened intercepting arms 10, the two intercepting arms 10 gradually close, and at this time, the ship body slows down.

[0078] When the ship body moves to the appropriate area, so that the lifting frame 5 is located above the large floating object, the hook 8 is lowered, the radiation lifting claws 9 suspended below the hook 8 are extended, each radiation lifting claw 9 grabs a lifting ring on the top of the large floating object, and then the clamping rod 13 is retracted to the original position. The winch 6 is started, and the large floating object rises with the hook 8;

[0079] The seat frame body 18 is extended under the action of the hydraulic push rod 19 to be directly below the large floating object, supports the large floating object, and locks the large floating object. Then the radiation lifting claws 9 are unlocked from the lifting ring of the large floating object and are retracted. Then the seat frame body 18 with the large floating object is retracted to the original position. At this time, the large floating object is just brought to the seat frame body 18 below the ejection rack 4. The personnel on the ship open the side door of the large floating object by standing in front of the connecting bridge deck or climb onto the ejection rack 4 and open the top door of the large floating object to provide personnel to exit the cabin.

[0080] Example four

[0081] When salvaging at the reef, at this time, the large floating object is located on the reef and is half exposed to water, close to the upright state, the operation method is as follows:

[0082] The ship body is moved out of the land warehouse by the track walking device 2. When the ship body moves to the intertidal shallow water area and the average draft has not reached the designed waterline, the ship body is subjected to considerable buoyancy, but the track walking device 2 is not completely separated from the ground due to the buoyancy, and the gripping force of the track walking device 2 is weakened, which is not conducive to walking. At this time, sea water can be injected into the ballast tank in the ship to appropriately offset part of the buoyancy, so as to ensure the gripping ability of the track walking device 2. When the ship body continues to move to the deep water area, the track walking device 2 is completely separated from the ground under the action of the buoyancy. At this time, the ballast sea water is discharged, and the ship body propulsion system is switched from the track walking device 2 to the rudder paddle propulsion device, and the ship body is pushed forward by the full-rotation rudder paddle 3.

[0083] In the above process, the intercepting arms 10 are in the closed state, and when the ship body sails to the working area and a large floating object is found floating on the sea surface, the intercepting arms 10 are opened, and a detection and feedback mechanism is installed on the intercepting arms 10 to detect the obstacles in front to prevent the intercepting arms 10 from colliding with the floating object. The two intercepting arms 10 open to the outside of the body 1, and at this time the ship body continues to sail towards the large floating object, and when it sails to the appropriate position, the ship body stops advancing, the frogman carries an automatic inflatable airbag ring with a rope into the water, the other end of the rope is connected to the ship body winch, the frogman climbs onto the rock, puts the airbag ring on the large floating object, and the airbag ring slides to the bottom of the large floating object, and then the airbag is automatically inflated, so that the large floating object floats up and separates from the rock, and the winch is started to pull the rope and drive the large floating object to gradually leave the rock and its attached shallow water area and enter the working area where the ship body can carry out sea salvage; the frogman cuts off the rope and the airbag ring.

[0084] The ship body sails slowly until the large floating object completely enters the inside of the fully opened front connecting line of the intercepting arms 10, and then the two intercepting arms 10 gradually close, the lifting hooks 8 are lowered, the radial lifting claws 9 suspended below the lifting hooks 8 are extended, each radial lifting claw 9 grabs a lifting ring on the top of the large floating object, and then the locking rod 13 is retracted to the original position, the winch 6 is started, and the large floating object rises with the lifting hooks 8.

[0085] The seat frame body 18 is extended straight under the large floating object under the action of the hydraulic push rod 19 provided on the seat frame moving mechanism, supports the large floating object, and locks the large floating object, and then the radial lifting claws 9 are unlocked from the lifting rings of the large floating object and are retracted, and then the seat frame body 18 with the large floating object is retracted to the original position, at this time the large floating object is just brought to the position directly below the ejection rack 4 by the seat frame body 18, and the personnel on the ship open the side door of the large floating object by standing in front of the connecting bridge deck or climb onto the ejection rack 4 and open the top door of the large floating object for personnel to exit the cabin.
