Description

Technical Field

[0001] This invention relates to the field of ship auxiliary equipment technology, specifically to an adaptive locking and shifting device for deck cargo. Background Technology

[0002] On the deck of a ship, especially on the deck of an engineering vessel or cargo ship, securing and adjusting the position of heavy cargo is a demanding and dangerous task.

[0003] Traditional methods mainly rely on fixed mooring points, using lashing rods, chains, etc. to secure cargo to pre-set lugs or bases on the deck. However, this method cannot easily adjust the cargo position. If fine adjustments are needed, all mooring points must be loosened, heavy machinery (such as forklifts) must be used to lift and move the cargo, and then it must be re-secured, which is extremely inefficient. Some methods use simple sliding rails, but positioning and locking the cargo on the rails is still difficult, especially when the ship is rocking, the cargo is prone to shifting, and the safety is poor. Therefore, an adaptive locking and shifting device for deck cargo is proposed. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides an adaptive locking and shifting device for deck cargo to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adaptive locking and shifting device for deck cargo, comprising: A load-bearing base, used to support goods that are to be moved and locked; The deck body, with the load-bearing seat positioned above the deck body; A hydraulic drive assembly, located inside the support base, is used to lift the support base to move up and down; The left and right outer surfaces of the load-bearing seat are equipped with adaptive locking mechanisms. The adaptive locking mechanisms lock the load-bearing seat and the cargo on it onto the deck body. The adaptive locking mechanisms include an autonomous adjustment component, a limiting component, and a transmission component. The limiting component is used to limit the autonomous adjustment component, and the transmission component is used to drive the autonomous adjustment component to rotate.

[0006] As a further explanation of the present invention, the hydraulic drive assembly includes a plurality of hydraulic cylinders, all of which are mounted on the top inner surface of the support base. A connecting plate is mounted on the output end of each hydraulic cylinder, and a set of casters is mounted below the connecting plate.

[0007] As a further explanation of the present invention, the self-adjusting component includes two support seats, both of which are installed outside the load-bearing seat. A rotating plate is rotatably connected inside the support seat. Two fixing blocks are fixedly connected to the outer surface of the rotating plate. A first spring is installed on the outer surface of one of the fixing blocks. A moving block is fixedly connected to the other end of the first spring. A locking pin is provided on one side of the moving block. The locking pin is perpendicular to the rotating plate.

[0008] As a further explanation of the present invention, the limiting component is used to limit the moving block. The limiting component includes a side plate disposed on one side of the two fixed blocks. An L-shaped plate is fixedly connected to the side of the side plate away from the fixed blocks. An electromagnet is installed on the side of the L-shaped plate facing the side plate. Two third springs are fixedly connected to the side of the L-shaped plate facing the side plate. An iron plate is fixedly connected to one end of each third spring. A plurality of second springs are disposed on the side of the iron plate facing the moving block. A limiting rod is disposed on the other end of each of the plurality of second springs. A plurality of limiting holes are opened on the side of the moving block facing the side plate.

[0009] As a further explanation of the present invention, the outer surface of the deck body is provided with a plurality of anchoring holes arranged in a standardized matrix, and the locking pin is inserted into one of the anchoring holes to lock the load-bearing seat.

[0010] As a further explanation of the present invention, the rotating assembly includes a support shaft that rotates through the space between two support seats, a rotating plate is fixedly sleeved on the outside of the support shaft, a gear is fixedly sleeved on the outer surface of the support shaft, mounting plates are fixedly installed on the outer surfaces of the left and right sides of the load-bearing seat, an electric push rod is installed on the bottom outer surface of the mounting plate, a rack is installed at the output end of the electric push rod, and the rack is movably meshed with the outer surface of the gear.

[0011] As a further explanation of the present invention, the omnidirectional wheel assembly is integrated below the connecting plate and achieves steering through a steering system driven by a motor and controlled by an external remote control to move forward, backward, laterally, and rotate in place.

[0012] As a further explanation of the present invention, the locking pin is tapered on the side facing the anchor hole, and the limiting rod is tapered at the end facing the limiting rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when the locking pin contacts the edge of the anchoring hole but does not fully correspond to the anchoring hole, as the locking pin moves downward, the edge of the anchoring hole is coated with oil to lock the pin, and the moving block moves, causing the first spring to deform. This allows the position of the locking pin to be adaptively adjusted so that the locking pin is fully inserted into the anchoring hole, thereby locking the goods and preventing them from shifting.

[0014] 2. In this invention, the hydraulic cylinder drives the universal wheel assembly to move downwards, so that the universal wheel assembly supports the load-bearing seat and the cargo, and makes the universal wheel assembly contact the deck body. The forward, backward, lateral and rotation of the universal wheel assembly can be controlled by remote control to achieve precise positioning of the cargo, eliminating the trouble of frequently using large cranes, and enabling remote fine-tuning of heavy cargo with high positioning accuracy.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please refer to the following: Figures 1-6 This invention provides a technical solution: an adaptive locking and shifting device for deck cargo, comprising a support seat 100, a deck body 500, and a hydraulic drive assembly, for supporting cargo to be moved and locked. The support seat 100 is disposed above the deck body 500, and the hydraulic drive assembly is located inside the support seat 100 for lifting the support seat 100 to move it up and down. Adaptive locking mechanisms are installed on the outer surfaces of both sides of the support seat 100. The adaptive locking mechanisms lock the support seat 100 and the cargo on it onto the deck body 500. The adaptive locking mechanism includes a self-adjusting assembly, a limiting assembly, and a transmission assembly. The limiting assembly is used to limit the self-adjusting assembly, and the transmission assembly is used to drive the self-adjusting assembly to rotate.

[0019] Specifically, by fixing the cargo to the load-bearing seat 100, and by using a hydraulic drive assembly to lift the load-bearing seat 100 up and down and drive the load-bearing seat 100 to move, the position of the cargo is adjusted. The load-bearing seat 100 and the cargo on it are locked to the deck body 500 by an adaptive locking mechanism, thereby increasing the stability of the cargo.

[0020] The edges of the load-bearing seat 100 are equipped with hanging rings. When goods are stacked on the load-bearing seat 100, the goods are secured by connecting the fixing ropes, chains, steel ropes and other components to the hanging rings.

[0021] In this embodiment, the self-adjusting component includes two support seats 300, both of which are installed outside the load-bearing seat 100. A rotating plate 301 is rotatably connected inside the support seat 300. Two fixing blocks 302 are fixedly connected to the outer surface of the rotating plate 301. A first spring 303 is installed on the outer surface of one of the fixing blocks 302. A moving block is fixedly connected to the other end of the first spring 303. A locking pin 304 is provided on one side of the moving block. The locking pin 304 is perpendicular to the rotating plate 301.

[0022] Specifically, when the locking pin 304 contacts the edge of the anchoring hole 501 but does not fully correspond to the anchoring hole 501, as the locking pin 304 moves downward, the inner wall of the anchoring hole 501 presses against the tapered part of the locking pin 304, thereby driving the moving block to move and causing the first spring 303 to deform. Thus, the compression of the first spring 303 provides a tolerance space for the locking pin 304 to insert into the anchoring hole 501.

[0023] A sliding rod is provided between the two fixed blocks 302, and the movable block is movably sleeved on the outside of the sliding rod. The sliding rod limits the movement of the movable block, so that the movable block can move in a stable linear motion.

[0024] In this embodiment, the limiting component is used to limit the moving block. The limiting component includes a side plate 400 disposed on one side of the two fixed blocks 302. An L-shaped plate 401 is fixedly connected to the side of the side plate 400 away from the fixed blocks 302. An electromagnet 402 is installed on the side of the L-shaped plate 401 facing the side plate 400. Two third springs 407 are fixedly connected to the side of the L-shaped plate 401 facing the side plate 400. An iron plate 403 is fixedly connected to one end of the third spring 407. A plurality of second springs 404 are disposed on the side of the iron plate 403 facing the moving block. A limiting rod 405 is disposed on the other end of each of the plurality of second springs 404. A plurality of limiting holes 406 are opened on the side of the moving block facing the side plate 400.

[0025] Specifically, when electromagnet 402 is energized, it attracts iron plate 403, causing third spring 407 to deform. Iron plate 403 moves limiting rod 405, causing limiting rod 405 to disengage from the limiting hole 406, releasing the moving block from its position. Electromagnet 402 is then de-energized, causing third spring 407 to reset. Third spring 407 then moves iron plate 403 back to its original position, ensuring that at least one tapered portion of limiting rod 405 contacts one of the limiting holes 406, thus limiting the moving block. The limiting rod 405 not in contact with the limiting hole 406 contacts the surface of the moving block, causing second spring 404 to deform. The L-shaped plate 401 has a guide rod fixedly connected to its outer surface, and the iron plate 403 is movably sleeved on the outside of the guide rod, so that the iron plate 403 slides on the outer surface of the guide rod when it moves, and the iron plate 403 moves stably in a straight line.

[0026] A telescopic rod is provided between the iron plate 403 and the limiting rod 405. When the limiting rod 405 moves, the telescopic rod moves accordingly, so that the telescopic rod moves stably in a straight line.

[0027] The outer surface of the side plate 400 has a through hole, and multiple limit rods 405 are located inside the through hole.

[0028] The spacing between the multiple limiting rods 405 is uneven, so that after the moving block moves, the end of at least one limiting rod 405 can correspond to the inside of one of the limiting holes 406.

[0029] In this embodiment, the outer surface of the deck body 500 is provided with a number of anchoring holes 501 arranged in a standardized matrix, and the locking pin 304 is inserted into one of the anchoring holes 501 to lock the load-bearing seat 100.

[0030] Specifically, the locking pin 304 is inserted into one of the anchoring holes 501 to lock the load-bearing seat 100, thereby increasing the stability of the load-bearing seat 100 and preventing the goods from shifting.

[0031] In this embodiment, the rotating assembly includes a support shaft 603 that rotates through the space between two support seats 300. A rotating plate 301 is fixedly sleeved on the outside of the support shaft 603. A gear 602 is fixedly sleeved on the outer surface of the support shaft 603. Mounting plates are fixedly installed on the outer surfaces of both sides of the load-bearing seat 100. An electric push rod 600 is installed on the bottom outer surface of the mounting plate. A rack 601 is installed at the output end of the electric push rod 600. The rack 601 and the outer surface of the gear 602 are movably meshed.

[0032] Specifically, when the electric push rod 600 retracts, it drives the rack 601 to move. The rack 601 meshes with the gear 602, causing the gear 602 to rotate. The gear 602 then drives the support shaft 603 to rotate, causing the rotating plate 301 on it to rotate. This makes the locking pin 304 perpendicular to the deck body 500. When the electric push rod 600 extends, it makes the locking pin 304 parallel to the deck body 500.

[0033] The stroke of the electric actuator 600 is L, L=(1 / 4)×π×d, where d is the pitch circle radius of gear 602. Assuming that the pitch circle diameter of gear 602 is d=40cm, then L= (1 / 4)×3.14×40=31.4cm.

[0034] In this embodiment, the locking pin 304 is tapered on the side facing the anchor hole 501, and the limiting rod 405 is tapered at one end.

[0035] Specifically, the locking pin 304 is tapered at the end, allowing it to be inserted into the anchoring hole 501 with some error. When the locking pin 304 contacts the edge of the anchoring hole 501 but does not completely correspond to it, as the locking pin 304 moves downward, the inner wall of the anchoring hole 501 presses against the tapered part of the locking pin 304. By setting one end of the limiting rod 405 into a tapered shape, the tapered part of the limiting rod 405 can be inserted into the limiting hole 406, so that at least one tapered part of the limiting rod 405 contacts one of the limiting holes 406, thereby limiting the moving block by the limiting rod 405. Example 2: Please refer to the following: Figures 1-6This invention provides a technical solution: a hydraulic drive assembly includes multiple hydraulic cylinders 200, all of which are mounted on the top inner surface of the load-bearing seat 100. A connecting plate 201 is mounted on the output end of each hydraulic cylinder 200, and a set of universal wheels 202 is mounted below the connecting plate 201. Specifically, when the hydraulic cylinders 200 operate, they drive the connecting plate 201 to move downwards, causing the universal wheels 202 to contact the deck body 500, which in turn causes the load-bearing seat 100 to move upwards. This allows the weight of the load-bearing seat 100 and the cargo to be fully applied to the universal wheels 202. The universal wheels 202 can be controlled by a remote control to move forward, backward, laterally, and rotate in place, achieving precise positioning of the cargo. When the hydraulic cylinders 200 retract, the load-bearing seat 100 contacts the deck body 500, and the weight of the cargo and the load-bearing seat 100 is borne by the deck body 500.

[0036] In this embodiment, the omnidirectional wheel assembly 202 is integrated below the connecting plate 201 and achieves steering through a steering system. It is driven by a motor and controlled by an external remote control to move forward, backward, laterally, and rotate in place.

[0037] Specifically, when the omnidirectional wheel assembly 202 comes into contact with the deck body 500, it is controlled by an external remote controller to move forward, backward, laterally, and rotate in place, thereby precisely controlling the position of the cargo. The omnidirectional wheel assembly 202, the steering system, and the remote control system are known existing technologies, and they are only used without modification. Therefore, their specific structure is not described in detail.

[0038] Working Principle: In use, the cargo is secured to the load-bearing seat 100 using straps or chains. When the cargo position needs to be adjusted, the hydraulic cylinder 200 operates, causing the connecting plate 201 to move downwards, bringing the caster wheel assembly 202 into contact with the deck body 500. This causes the load-bearing seat 100 to move upwards, ensuring that the weight of the load-bearing seat 100 and the cargo is fully distributed across the caster wheel assembly 202. The caster wheel assembly 202 can be remotely controlled to move forward, backward, laterally, and rotate in place, achieving precise positioning of the cargo and moving it to the desired location. After reaching the appropriate position, the electric push rod 600 is activated, retracting to move the rack 601. The rack 601 meshes with the gear 602, causing the gear 602 to rotate. The gear 602 then rotates the support shaft 603, causing the rotating plate 301 on it to rotate. This makes the locking pin 304 perpendicular to the deck body 500, energizing the electromagnet 402. The electromagnet 402 attracts the iron plate 403, causing the third spring 407 to deform. The iron plate 403 then moves the limiting rod 405, causing the limiting rod 405 to move from the limit position. The internal part of the positioning hole 406 disengages, releasing the limiting position of the moving block. Then, it retracts via the hydraulic cylinder 200, causing the load-bearing seat 100 to contact the deck body 500. The weight of the cargo and the load-bearing seat 100 is borne by the deck body 500. At this time, the locking pin 304 corresponds to the nearest anchoring hole 501 and is inserted into it. When the locking pin 304 contacts the edge of the anchoring hole 501 but is not fully aligned, as the locking pin 304 moves downward, the inner wall of the anchoring hole 501 presses against the tapered part of the locking pin 304, thereby... The moving block is moved, causing the first spring 303 to deform. The compression of the first spring 303 provides a tolerance space for the locking pin 304 to insert into the anchoring hole 501. Then, the electromagnet 402 is de-energized, causing the third spring 407 to reset. The third spring 407 drives the iron plate 403 to reset, and at least one of the tapered parts of the limiting rod 405 contacts one of the limiting holes 406, thereby limiting the moving block through the limiting rod 405. The limiting rod 405 that does not contact the limiting hole 406 contacts the surface of the moving block, causing the second spring 404 to deform.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
