Description

Technical Field

[0001] The invention relates to intelligent forming equipment for hull outer plate, and in particular to air supply equipment for intelligent forming equipment for hull outer plate. Background Art

[0002] Before sailing, ships will install lifeboats and lifebuoys on the outside of the hull for emergency avoidance of water disasters, which is an important safety reserve for ship navigation. In order to ensure navigation safety, reduce the space occupied by the hull, and prevent affecting the navigation speed of the ship, the lifeboats and lifebuoys on the ship are generally in an uninflated state to reduce their own volume. When in use, they are quickly inflated. The inflated lifeboats and lifebuoys can float on the water surface and use the buoyancy of the water to provide support.

[0003] After searching, the patent document with the announcement number CN 216508885 U discloses an air supply device for intelligent forming equipment of hull outer plate, which hides the air supply device inside the side of the hull, makes full use of the redundant space of the hull, controls the access of the carrying platform, and facilitates the inflation of external equipment and the inspection and maintenance of facilities such as air pumps. The air supply facilities are closer to the equipment installed on the carrying platform, and the air ducts provided by the group air pumps can be used to inflate different equipment at the same time, which greatly improves the inflation rate. When the equipment is not in use, the carrying platform is retracted into the hull, which can protect the air pump and power supply lines and prevent them from being corroded by seawater and air.

[0004] However, when the ship sinks rapidly, the lifeboat may not be fully inflated, making it impossible for the passengers to escape in time. Furthermore, since the end of the inflation tube is in a locked docking state with the lifeboat, the passengers will not have time to separate the two. The sinking ship may cause the lifeboat to tilt downward due to the traction of the inflation tube, causing it to tip over (or the inflation hole may tear and leak), causing the passengers on the lifeboat to fall into the water.

[0039] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] The following describes an embodiment of the present invention based on its overall structure.

[0042] A partition 250 is fixed at a transversely centered position in the operating chamber 220, two sets of driving shafts 290 are fixed at the bottom end of the partition 250 near the rear surface of the partition 250, the bottom end of the driving shaft 290 extends to the top of the carrier plate 100, an inner eight groove 110 is provided at the contact position between the top of the carrier plate 100 and the two sets of driving shafts 290, a transverse groove 260 is provided at the contact position between the bottom end of the frame seat 210 and the driving shaft 290, a steel wire rope 240 arranged in a U shape is fixed to the curved outer wall of the driving shaft 290, the end of the steel wire rope 240 is fixed to the top of the support assembly 400, and two sets of reversing wheels 241 located at the bending position of the steel wire rope 240 are rotatably provided on the lower inner wall of the operating chamber 220;

[0043] The support assembly 400 includes an L seat 410 slidably arranged in the U groove 230, the end of the wire rope 240 is fixed to the top of the L seat 410, the top of the L seat 410 is equipped with a locking frame 420, and the two sides of the locking frame 420 are equipped with frame 440. The locking frame 420 is equipped with a diamond frame 430 that is rotatably connected to the frame 440 on both sides. The middle and end parts of the diamond frame 430 are provided with a base shaft 431 that is rotatably arranged with the locking frame 420 and the frame 440, and the top of each group of frame 440 is provided with two groups of storage slots. 443, a right-angle plate 441 is assembled in the storage slot 443, two groups of locking blocks 480 are fixed to the bottom end of the locking frame 420, a shallow groove 411 is provided at the contact position between the L seat 410 and the two groups of locking blocks 480, a locking frame 412 which is slidably provided in the shallow groove 411 and is engaged with the locking block 480, a yielding groove 423 is provided at the bottom of the locking frame 420, a driven plate 422 connected to the bottom end of the base shaft 431 is slidably provided in the yielding groove 423, and a first sliding groove 421 for the base shaft 431 to slide is provided in the yielding groove 423.

[0044] The control hydraulic cylinder 120 pushes the frame seat 210 to slide forward on the top of the carrier plate 100 so that it extends out of the outside of the hull. The two sets of driving shafts 290 will move toward the middle due to the constraints of the inner eight grooves 110, and under the limiting effect of the transverse grooves 260, the two sets of driving shafts 290 will be located at the top of the carrier plate 100 and close to the center of the front surface as the frame seat 210 moves. The two sets of driving shafts 290 will pull the wire rope 240 to move along the preset trajectory, so that the support assembly 400 moves synchronously with the frame seat 210 and extends out of the frame seat 210. 0, at this time, an external force can be applied to the frames 440 on both sides away from the locking frame 420, and the end of the diamond frame 430 and the base shaft 431 in the middle will slide in the first slide groove 421 and the second slide groove 442, and the diamond frame 430 is gradually stretched and unfolded, and at the same time, the right-angle plate 441 is opened and erected on the top of the frame 440 and in a relative state. At this time, the deflated lifeboat can be spread on the platform formed by the locking frame 420, the frame 440 and the diamond frame 430, and the lifeboat can be inflated;

[0045] The handle 331 is held and a certain pulling force is applied to drive the hose 340 to extend out of the frame 210, and the hose 340 is connected to the inflation port of the lifeboat. When the frame 210 is extended, the two sets of driving shafts 290 are relatively close to each other, and the two sets of slats 280 fixedly connected to the driving shaft 290 are close to each other, so that the restraining wheel 251 located on the inner side of the hose 340 moves synchronously, and the restraint of the folded hose 340 is released. As the pulling force is applied to the handle 331, the hose 340 can be smoothly extended out of the frame 210, so as to prevent the hose 340 from being intertwined and affecting the inflation efficiency. Multiple handles 331 can inflate multiple lifeboats and lifebuoys at the same time to carry more escapees.

[0046] After the lifeboat is inflated, the hook 451 located on the outside of the frame 440 is connected to the anchor rope on the outer wall of the lifeboat, and the unfolded diamond frame 430, the locking frame 420 and the frame 440 are stably placed on the bottom of the lifeboat under the connection of the elastic rope 450, which plays a certain protective role for the lifeboat. Finally, the handle screw rod 460 is manually rotated to make the traction arm 470 drive the locking frame 412 to move, so that the lock between the locking frame 412 and the clamping rod 482 is released. At this time, the lifeboat can be lifted and thrown into the water, and people can enter the lifeboat one by one.

[0047] When the boat sinks quickly or has sunk below the water surface before the lifeboat is fully inflated, the passengers can directly enter the lifeboat. Since the load-bearing plate 100 is fixed to the boat, the hose 340 will generate a pulling force (pulling force inclined toward the water) on the lifeboat. At this time, the hose 340 will separate from the handle 331 due to the pulling force, and no additional pulling force will be generated on the lifeboat. When the boat sinks, the deployed support assembly 400 will also be driven to contact the water surface and have a certain draft. At this time, the water will exert a pulling force on the diamond frame 430 and the frame 44 of the floating plate material. 0 and the locking frame 420 generate an upward buoyancy, which drives the driven plate 422 to move upward in the give way groove 423 through the base shaft 431, and the driven bar 481 fixed at the bottom moves accordingly, and the middle part of the pulling cable 483 is bent downward, so that the clamping rods 482 at both ends are retracted into the locking block 480, so that the lock between the locking frame 420 and the L seat 410 can be released by the buoyancy of water, so as to realize the separation of the locking frame 420, the frame 440 and the diamond frame 430 from the L seat 410 that sinks together with the hull, without manual operation, which can better ensure the personal safety of the personnel supporting the hull.

[0048] See also Fig. 9 , body 10 and Fig.11 The inner wall of the frame 440 is provided with a second sliding groove 442 for the base shaft 431 to slide, two groups of base rods 445 are fixed on the inner wall of the storage groove 443 and near the end, and a straight groove 444 is provided at the outer wall of the right-angle plate 441 and the corresponding position of the base rod 445.

[0049] By providing the second sliding groove 442, the end of the diamond frame 430 has a sliding space, so that the rotation and folding of the diamond frame 430 are not restricted, ensuring that the two sets of frame frames 440 can be relatively far apart and opened;

[0050] The right angle plate 441 is rotated with the base rod 445 as the base point to be in an upright state, and a vertical downward external force is applied to the right angle plate 441, so that the right angle plate 441 slides into the storage groove 443, and the base rod 445 slides along the straight slot 444, so that the right angle plate 441 remains in an upright state.

[0051] See also Fig.12 and Fig.13 The bottom end of the base shaft 431 is connected to the top of the driven plate 422 through a dovetail block. A dovetail groove that matches the dovetail block is opened on the top of the driven plate 422. The diamond frame 430 is connected to the outer wall of the base shaft 431 through a bearing. The diamond frame 430 and the frame 440 are both made of floating plate materials. A hidden groove is reserved on the outer wall of the frame 440. An elastic rope 450 is fixed in the hidden groove. The free end of the elastic rope 450 is connected to a hook 451.

[0052] The dovetail block is used to allow the base shaft 431 to slide on the top of the driven plate 422 as the state of the diamond frame 430 changes, thereby preventing the diamond frame 430 from being obstructed. When the diamond frame 430 and the frame 440 are in contact with the water surface, the buoyancy generated can make the diamond frame 430 and the frame 440 rise to a certain height, and the elastic rope 450 is taken out to make the hook 451 at the end hook with the cable of the outer wall of the lifeboat, so that the diamond frame 430 and the frame 440 are firmly located at the bottom of the lifeboat.

[0053] See also Fig.12 , Fig.13 and Fig.15 The end of the L seat 410 away from the carrier plate 100 is rotatably provided with a handle screw 460, the outer wall of the handle screw 460 is threadedly sleeved with a traction arm 470, the end of the traction arm 470 is fixed to the outer wall of the lock frame 412, the lock frame 412 is slidably arranged with a slider on the inner wall of the shallow groove 411, an operating groove is opened in the L seat 410 at a position in contact with the traction arm 470 and the handle screw 460, and two sets of card slots 413 are opened on the inner wall of the L seat 410;

[0054] Restraining blocks sliding on the inner wall of the U groove 230 are provided on both sides of the L seat 410. The inner wall of the U groove 230 is provided with a sliding groove for the restraining blocks to slide, which can prevent the L seat 410 from falling when the frame seat 210 extends forward, and play a supporting role for the lifeboat after being deflated and inflated.

[0055] Two groups of locking rods 482 extending into the slots 413 are slidably provided in each group of locking blocks 480, a cable 483 is fixed to one end close to the two groups of slots 413, a follower bar 481 fixed to the bottom end of the follower plate 422 is provided in the transverse middle position of the cable 483, a T-slot is provided in the locking block 480 at a position in contact with the locking rod 482 and the follower bar 481, a spring 484 fixed to the outer wall of the locking rod 482 is mounted on the outer wall of the locking rod 482, and the other end of the spring 484 is fixed to the outer wall of the locking rod 482.

[0056] An external force can be manually applied to the handle screw 460 to rotate it, so that the traction arm 470 drives the lock frame 412 to move. At this time, the card slot 413 slides on the outer wall of the end of the card rod 482. When the handle screw 460 cannot be rotated further, the support assembly 400 can be lifted upward and put into the water surface;

[0057] When the present invention contacts the water surface, the water surface generates an upward force on the diamond frame 430 and the two sets of frame frames 440, which drives the clamping rod 482 to retract into the locking block 480, automatically releasing the lock between the clamping rod 482 and the locking frame 412, so that the support assembly 400 can be automatically detached.

[0058] See also Figure 3 , Figure 4 and Fig.17 The inflation assembly 300 includes an inflation pump 310 installed on the top of the frame seat 210.

The end of the handle 331 close to the second metal L-tube 334 is in an open trumpet shape. A rubber cone plug connected to the open end is fixed to the outer wall of the second metal L-tube 334.

[0060] When the boat has sunk, the hose 340 will generate pulling force on the handle 331 connected to the lifeboat. Since the docking nozzle 332 is locked with the lifeboat, the second metal L-tube 334 will be pulled to one side, and the trapezoidal ring 333 on the outer wall will push the ladder block 339 and the abutment strip 335 to move accordingly. The guide column 337 slides along the guide groove 338, which will cause the abutment strip 335 to gradually move away from the trapezoidal ring 333. When the interval between the two groups of ladder blocks 339 is larger than the outer wall diameter of the trapezoidal ring 333, the second metal L-tube 334 will be separated from the movable handle 331 and no longer generate pulling force on the lifeboat, ensuring that the passengers are safely in the lifeboat.

[0061] The air pump 310 no longer generates a blowing force on the one-way valve sheet, and the one-way valve sheet will close and block the docking nozzle 332 to prevent the gas in the lifeboat from being discharged;

[0062] The elastic member 336 will hinder the movement of the resistance slat 335, so that there is a certain connection force between the second metal L-tube 334 and the handle tube 331, ensuring that normal in and out inflation can be achieved when the handle tube 331 is manually held to drive the hose 340 to extend, and the rubber cone plug can fill the space between the outer wall of the second metal L-tube 334 and the handle tube 331, which can improve the appearance and prevent the second metal L-tube 334 from bending.

[0063] See also Figures 1 to 3 The outer wall of the frame seat 210 and the inflation head mechanism 330 are provided with a storage groove, and a rubber pad is fixed in the storage groove.

[0064] The storage groove provides storage space for the inflation head mechanism 330, and the rubber pad can increase the friction between the frame seat 210 and the inflation head mechanism 330, prevent the inflation head mechanism 330 from falling off, and conveniently and quickly take out the inflation head mechanism 330 to inflate the lifeboat.

[0065] See also Figure 4 and Figure 6 , multiple groups of hoses 340 are placed in an upper and lower stacked state, and a layered plate 270 fixed to the inner wall of the operating chamber 220 is provided between the upper and lower groups of hoses 340, and a straight groove 271 is provided at the corresponding position of the layered plate 270 and the constraint wheel 251, and the top of the partition 250 is located at the inner side of the return-shaped hose 340 and has multiple groups of travel grooves 252, and the bottom of the partition 250 and is located at the edge position and is slidably provided with a slat 280 fixed to the top of the active shaft 290, and the slat 280 is located directly below the constraint wheel 251 at the edge position, and the top of the slat 280 is fixed and slidably provided with a bottom block 281 in the travel groove 252, and the top of the bottom block 281 is rotatably connected to the bottom end of the constraint wheel 251 at the edge position, and balls are fixed on both sides of the bottom block 281, and the inner wall of the travel groove 252 is provided with a ball groove that matches the ball;

[0066] A plurality of sets of restraining wheels 251 are rotatably provided on the top of the partition 250 , and each set of restraining wheels 251 is located at the inner side of the bend of the hose 340 .

[0067] Multiple air pumps 310 can simultaneously inflate multiple lifeboats and lifebuoys to carry more escapees;

[0068] When the frame 210 is pushed out, the restraining wheel 251 at the edge position will be driven to move toward the middle along the straight groove 271, thereby releasing the restraint on the hose 340. The layered plate 270 prevents the upper and lower sets of hoses 340 from winding, ensuring that the hoses 340 can be smoothly extended when the handle 331 is held, thereby ensuring the efficiency of inflating the lifeboat.

[0069] The multiple bottom blocks 281 can make the constraint wheel 251 move synchronously and ensure the normal rotation of the constraint wheel 251, reducing the friction force on the hose 340 when moving. The bottom block 281 moves in a straight line along a preset trajectory in the travel groove 252, and the ball and the ball groove cooperate to make it move more smoothly.

[0070] When in use, the control hydraulic cylinder 120 pushes the frame seat 210 to slide forward on the top of the carrier plate 100, so that the frame seat 210 extends out of the outside of the hull, and the two sets of driving shafts 290 will move closer to the middle due to the constraints of the inner eight grooves 110, and under the limiting effect of the transverse grooves 260, the two sets of driving shafts 290 will be located at the top of the carrier plate 100 and close to the center of the front surface as the frame seat 210 moves. The two sets of driving shafts 290 pull the wire rope 240 to move according to the preset trajectory, so that the support assembly 400 moves synchronously with the frame seat 210. and extends out in front of the frame seat 210. At this time, an external force can be applied to the frame 440 on both sides away from the locking frame 420. The base shaft 431 at the end and the middle of the diamond frame 430 will slide in the first slide groove 421 and the second slide groove 442, and the diamond frame 430 will be gradually stretched and unfolded. At the same time, the right-angle plate 441 is moved to stand on the top of the frame 440 and in a relative state. At this time, the deflated lifeboat can be spread on the platform formed by the locking frame 420, the frame 440 and the diamond frame 430, and the lifeboat can be inflated.

[0071] The handle 331 is held and a certain pulling force is applied to drive the hose 340 to extend from the frame 210, and the clamping rod 482 is connected to the inflation port of the lifeboat. When the frame 210 is extended, the two sets of driving shafts 290 are relatively close to each other, and the two sets of slats 280 fixedly connected to the driving shaft 290 are close to each other, so that the restraining wheel 251 located on the inner side of the hose 340 moves synchronously, and the restraint of the hose 340 in a folded shape is released. When the handle 331 is pulled, it can be smoothly extended from the frame 210, so as to prevent the hose 340 from being intertwined and affecting the inflation efficiency. Multiple handles 331 can inflate multiple lifeboats and lifebuoys at the same time to carry more escapees.

[0072] After the lifeboat is inflated, the hook 451 located on the outside of the frame 440 can be connected to the anchor rope on the outer wall of the lifeboat, and the unfolded diamond frame 430, the locking frame 420 and the frame 440 can be stably placed on the bottom of the lifeboat under the connection of the elastic rope 450, which plays a certain protective role for the lifeboat. Finally, the handle screw rod 460 is manually rotated to make the traction arm 470 drive the locking frame 412 to move, and the lock between the locking frame 412 and the clamping rod 482 is released. At this time, the lifeboat can be lifted and thrown into the water, and people can enter the lifeboat one by one.

[0073] When the boat sinks quickly or the lifeboat has sunk below the water surface before the inflation is completed, the support plate 100 is fixed to the boat, and a pulling force (pulling force inclined toward the water) is generated on the lifeboat under the action of the hose 340. At this time, the hose 340 is separated from the handle 331 due to the pulling force, and no additional pulling force is generated on the lifeboat. When the boat sinks, the unfolded support assembly 400 is also driven to contact the water surface and has a certain draft. Since this water generates an upward buoyancy on the diamond frame 430, the frame 440 and the locking frame 420 made of the floating plate material, the base shaft 4 The driven plate 422 is driven to move upward in the clearance groove 423, and the driven bar 481 fixed at the bottom moves accordingly, and the middle part of the cable 483 is bent downward, so that the clamping rods 482 at both ends are retracted into the locking block 480, so that the buoyancy of the water can be used to release the lock between the locking frame 420 and the L seat 410, so as to realize the separation of the locking frame 420, the frame 440 and the diamond frame 430 from the L seat 410 that sinks together with the hull, without manual operation, which can better ensure the personal safety of the personnel supporting the hull. The parts not involved in the device are the same as the prior art or can be realized by the prior art.
