Description

Technical Field

[0001] This invention relates to the field of lifting and hoisting equipment technology, specifically a hoisting frame for hoisting ship pipe modules. Background Technology

[0002] Modular construction of ship piping systems has become a core development direction in modern shipbuilding. With the increasing precision requirements and shortening construction cycles in shipbuilding, traditional piecemeal pipe installation processes are no longer sufficient to meet the demands of efficient shipbuilding. The process of pre-assembling numerous loose pipes into modular pipe units, and then hoisting them into the hold for installation, has gained widespread application in large shipyards both domestically and internationally due to its significant advantages, such as increased pre-outfitting rates, shorter dock cycles, and improved working environments. One of the key technologies in the pipe module hoisting process lies in the design and application of the hoisting grate. As a transitional lifting device connecting lifting equipment and piping modules, the performance of the hoisting grate directly determines the safety, efficiency, and finished quality of the pipes during module hoisting.

[0003] Currently, with the increasing demands of shipbuilding, the pipe modules of some large ships are becoming larger and larger. However, the existing lifting racks used for lifting ship pipe modules are relatively small and cannot meet the lifting requirements of larger pipe modules. This presents certain limitations and shortcomings when lifting large pipe modules. Therefore, we propose a lifting rack for lifting ship pipe modules. Summary of the Invention

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Please see Figures 1 to 10 This invention provides a technical solution: a lifting platform for hoisting ship pipe modules, comprising: Main hoist 1; Secondary hoist 2; The first connecting plate 3 is respectively connected to the main hoist 1 and the auxiliary hoist 2; The second connecting plate 4 is connected and fitted with the main hoist 1 and the auxiliary hoist 2; The inner sides of the main hoisting rod 1 and the auxiliary hoisting rod 2 are equipped with lifting frames 5. The top of the main hoisting rod 1 is equipped with two main connecting plates 6. The sides of the main connecting plates 6 are equipped with first reinforcing ribs 7. Two connecting holes 8 are opened through the main connecting plates 6. The top of the auxiliary hanging rack 2 is provided with two auxiliary connecting plates 9 that cooperate with the main connecting plate 6. A second reinforcing rib 10 is provided on one side of the auxiliary connecting plate 9, and a connecting mechanism that cooperates with the connecting hole 8 is provided on the other side of the auxiliary connecting plate 9. The main hoisting frame 1 serves as the basic load-bearing unit, while the auxiliary hoisting frame 2 serves as an extended load-bearing unit, both of which can be used in combination with the main hoisting frame 1. The first connecting plate 3 is used in conjunction with both the main hoisting frame 1 and the auxiliary hoisting frame 2, and can be connected to either the main hoisting frame 1 or the auxiliary hoisting frame 2 individually, or simultaneously with the overall structure formed by combining the two. The second connecting plate 4 is used to further fix the relative positions of the main hoisting frame 1 and the auxiliary hoisting frame 2 from above or below after the main hoisting frame 1 and the auxiliary hoisting frame 2 have been connected laterally or longitudinally, thereby enhancing the overall rigidity and hoisting stability. The longitudinal and transverse beams inside the frames of the main hoisting frame 1 and the auxiliary hoisting frame 2 are arranged in an interlaced manner to form multiple rectangular units, which effectively reduces the self-weight while ensuring structural strength. The main lifting platform 1 and the auxiliary lifting platform 2 can be used independently when lifting small-sized ship pipe units. When the outer dimensions of the pipe module are smaller than the inner diameter of the frame of the main lifting platform 1 or the auxiliary lifting platform 2, one of the lifting platforms can be used directly. The lifting can be completed by connecting the lifting points of the pipe module with the lifting cable. The operation is simple and efficient. When the required ship pipe unit is large and cannot be lifted by the main lifting rack 1 or auxiliary lifting rack 2 alone, the main lifting rack 1 and auxiliary lifting rack 2 can be connected at their ends (spliced ​​along the length) or connected on the front and rear sides (spliced ​​along the width) according to the volume and shape of the ship pipe unit. This increases the lifting area and meets the lifting needs of ship pipe units of different volumes. End connections are suitable for situations where the length dimension of the pipe module is large, forming a straight-line extended lifting rack; side connections are suitable for situations where the width dimension of the pipe module is large, forming a grid-shaped or H-shaped extended lifting rack. When a larger area is required, multiple sets of main lifting racks 1 and auxiliary lifting racks 2 can be alternately spliced ​​to achieve flexible expansion of the lifting area.

[0023] The connecting mechanism includes a first connecting rod 11, with a sliding hole 12 inside the first connecting rod 11. A through groove 13 is provided around the sliding hole 12. An installation shaft 14 is fixedly installed inside the through groove 13. A locking plate 15 is movably provided on the outside of the installation shaft 14. A slide rod 16 is slidably installed through one end of the first connecting rod 11. An end plate 17 is provided at one end of the slide rod 16. A second connecting rod 18 is hinged to the sides of the end plate 17. One end of the second connecting rod 18 is hinged to the locking plate 15. A first abutment plate 19 is provided on the outside of the slide rod 16. A first spring 20 that cooperates with the first abutment plate 19 is provided on the outside of the slide rod 16. A pull plate 22 is provided at the other end of the slide rod 16. When the main lifting plate 1 and the auxiliary lifting plate 2 are connected, the auxiliary lifting plate 2 is brought closer to the main lifting plate 1, so that the first connecting rod 11 on the side of the auxiliary connecting plate 9 is aligned with the connecting hole 8 on the main connecting plate 6. The auxiliary lifting plate 2 is then pushed further, and the end of the first connecting rod 11 passes through the connecting hole 8. At this time, the locking plate 15 at the end of the first connecting rod 11 is in an unfolded state, i.e., open outwards. The inclined surface on the outer side of the locking plate 15 contacts the inner wall edge of the connecting hole 8, and is subjected to radial pressure from the connecting hole 8. The radial component of this pressure pushes the locking plate 15 to rotate inwards about the mounting shaft 14 towards the sliding hole 12, i.e., tilt inwards. When the locking plate 15 rotates inward, it pushes the end plate 17 away from the locking plate 15 via the second connecting rod 18, and the end plate 17 drives the slide rod 16 to move synchronously. When the slide rod 16 moves, the first abutment plate 19 compresses the first spring 20, causing the first spring 20 to be further compressed and store elastic potential energy. As the first connecting rod 11 continues to penetrate deeper into the connecting hole 8, the locking plate 15 is completely inserted into the interior of the connecting hole 8. At this time, there is a small gap or just contact between the outer surface of the locking plate 15 and the inner wall of the connecting hole 8. When the locking plate 15 has completely passed through the connecting hole 8, that is, when the free end of the locking plate 15 has fully extended to the other side of the main connecting plate 6, the radial constraint of the connecting hole 8 on the locking plate 15 is released. At this time, the elastic potential energy stored in the first spring 20 is released, pushing the first abutment plate 19 to reset the slide rod 16 towards the locking plate 15. The slide rod 16 drives the end plate 17 to move towards the locking plate 15, and the end plate 17 pushes the locking plate 15 to rotate outward about the mounting shaft 14 through the second connecting rod 18, thus unfolding it. After the locking plate 15 is unfolded, its outer side abuts against the side of the main connecting plate 6, that is, the side away from the auxiliary connecting plate 9, thereby limiting it on one side of the main connecting plate 6 and preventing the first connecting rod 11 from coming out of the connecting hole 8. At this point, the connection between the main lifting rod 1 and the auxiliary lifting rod 2 is completed. The whole process is simple to operate, requires no additional tools, and the connection is firm and reliable. When it is necessary to separate the main lifting rod 1 and the auxiliary lifting rod 2, the operator manually pulls the pull plate 22 outwards, away from the first connecting rod 11, causing the sliding rod 16 and the end plate 17 to move away from the locking plate 15. As the end plate 17 moves, it pulls the locking plate 15 via the second connecting rod 18, causing the locking plate 15 to rotate inwards about the mounting shaft 14 towards the sliding hole 12. When the locking plate 15 is fully retracted into the sliding hole 12, meaning its outer surface does not exceed the outer contour of the first connecting rod 11, the locking plate 15 releases its restriction on the main connecting plate 6. At this point, the operator moves the auxiliary lifting rod 2 laterally away from the main lifting rod 1, allowing the first connecting rod 11 to be completely pulled out of the connecting hole 8, thus completing the separation of the main lifting rod 1 and the auxiliary lifting rod 2. After releasing the pull plate 22, the first spring 20 will automatically reset the sliding rod 16 and the locking plate 15, preparing for the next connection.

[0024] A limiting rod 21 that mates with the end plate 17 is provided on one side inside the sliding hole 12; The limiting rod 21 serves to limit and block the position of the end plate 17, preventing it from moving too far away from the locking plate 15. If the end plate 17 moves too far, the second connecting rod 18 may excessively pull the locking plate 15, potentially causing the locking plate 15 to rotate beyond its design range, affecting the fit accuracy between the locking plate 15 and the main connecting plate 6, and even causing plastic deformation of the locking plate 15 or the second connecting rod 18. The limiting rod 21 ensures that the locking plate 15's retraction angle in the unlocked state is just right, facilitating the removal of the first connecting rod 11 from the connecting hole 8 without damaging the transmission components.

[0025] The end of the first connecting rod 11 is provided with a cone head 23; A conical head 23 is provided at the end of the first connecting rod 11. This design allows the first connecting rod 11 to slide smoothly into the connecting hole 8 even if there is a certain parallel deviation between the axis of the first connecting rod 11 and the axis of the connecting hole 8. This conical head 23 provides guidance, ensuring the first connecting rod 11 slides smoothly into the connecting hole 8. This significantly reduces the alignment accuracy requirements when the main lifting rod 1 and the auxiliary lifting rod 2 are connected, improving the convenience and efficiency of on-site operation.

[0026] The top of the connection point of the lifting frame 5 is provided with a first hanging lug 24, and the bottom of the connection points between the main lifting rod 1 and the auxiliary lifting rod 2 and the lifting frame 5 are provided with a second hanging lug 25; With the first lug 24 installed, the hoisting cable can be connected to the hook of the lifting equipment to achieve the overall lifting of the hoisting platform. With the second lug 25 installed, the hoisting cable can be connected to the lifting point on the ship's pipe module to be lifted, suspending the pipe module below the hoisting platform for lifting.

[0027] The top of both ends and sides of the main hoist 1 and the auxiliary hoist 2 are hinged with a third connecting rod 26. The top of both ends and sides of the first connecting plate 3 and the second connecting plate 4 are provided with mounting seats 27. A connecting seat 28 is provided on one side of the mounting seat 27. A connecting groove that mates with the third connecting rod 26 is formed in the middle of the mounting seat 27 and the connecting seat 28. A threaded rod 29 is installed in the internal thread of the mounting seat 27. The end of the third connecting rod 26 is provided with a hole that mates with the threaded rod 29. When the main lifting platform 1 or the auxiliary lifting platform 2 needs to be connected to the first connecting plate 3, firstly, the first connecting plate 3 is hoisted above the main lifting platform 1 or the auxiliary lifting platform 2, so that the first connecting plate 3 is roughly aligned with the frame of the main lifting platform 1 or the auxiliary lifting platform 2. Then, the third connecting rod 26 is flipped upward, causing it to rotate upward around the hinge axis until the free end of the third connecting rod 26 is inserted into the connecting groove in the middle of the mounting base 27 and the connecting base 28, and the hole at its end is aligned with the threaded rod 29. Finally, the threaded rod 29 is rotated so that it passes through the hole at the end of the third connecting rod 26 and is threadedly connected to or abuts against the connecting base 28, thus fixing the third connecting rod 26 in the connecting groove, thereby completing the fixed connection between the first connecting plate 3 and the main lifting platform 1 or the auxiliary lifting platform 2. Similarly, when the main lifting platform 1 and the auxiliary lifting platform 2 are connected and need to be connected to the second connecting plate 4, the same operation can be performed. By cooperating with the connecting plate, the relative displacement between the main hoisting rod 1, the auxiliary hoisting rod 2 and the connecting plate can be effectively limited, thereby enhancing the rigidity and anti-tilting ability of the overall structure.

[0028] The bottom of the first connecting plate 3 and the second connecting plate 4 are evenly provided with third hanging ears 30, and the top of the first connecting plate 3 and the second connecting plate 4 are evenly provided with fourth hanging ears 31. By providing the third lug 30, when the first connecting plate 3 is mounted on the main lifting frame 1 or the auxiliary lifting frame 2 and connected to it, it can be connected to the third lug 30 and the first lug 24 via the lifting cable, thereby further improving the firmness and stability of the connection between the first connecting plate 3 and the main lifting frame 1 and the auxiliary lifting frame 2. This dual connection method can effectively distribute the lifting load, reduce the stress on a single connection point, and improve safety redundancy. Similarly, the second connecting plate 4 can be connected to the main lifting frame 1 and the auxiliary lifting frame 2 in the same way as described above.

[0029] The lifting frame 5 is provided with several snap-fit ​​boxes 32 that cooperate with the third connecting rod 26. The snap-fit ​​box 32 has an inner sliding groove 33 in the middle. The inner sliding groove 33 has a fixed plate 34 fixedly installed inside both ends. The fixed plate 34 has a pin 35 that is slidably installed through it. The pin 35 passes through the side wall of the snap-fit ​​box 32 and is slidably connected to it. The outer side of the pin 35 is provided with a second base plate 36. The outer side of the pin 35 is provided with a second spring 37 that cooperates with the second base plate 36. One end of the pin 35 is fixedly installed with a handle 38. The third connecting rod 26 has a pin hole 39 that cooperates with the pin 35. When the third connecting rod 26 is not needed during hoisting, such as when the main hoisting rod 1 or the auxiliary hoisting rod 2 is used alone and there is no need to connect it to the first connecting plate 3 or the second connecting plate 4, the third connecting rod 26 needs to be stored and fixed to prevent it from swinging freely during hoisting and causing safety hazards. First, the operator uses two fingers or a tool to simultaneously pinch the two handles 38 in the inner slide groove 33 and pulls them towards each other, thereby moving the two pins 35 into the inner slide groove 33 of the snap-fit ​​box 32. When the pins 35 move, the second base plate 36 compresses the second spring 37, causing the second spring 37 to be further compressed and store elastic potential energy. At this time, the ends of the two pins 35 retract from the side wall of the snap-fit ​​box 32. Then, the operator rotates the third connecting rod 26 downwards, laying it flat and overlapping it on the lifting frame 5, so that the middle or end of the third connecting rod 26 is in the opening position of the snap-fit ​​box 32, and the pin hole 39 is aligned with the axis of the pin 35. Subsequently, the pull handle 38 is released, the elastic potential energy stored in the second spring 37 is released, pushing the second base plate 36 to reset the pin 35 towards the outside of the snap-fit ​​box 32. The ends of the two pins 35 are simultaneously inserted into the pin holes 39 on the third connecting rod 26 from both sides, thereby fixing the third connecting rod 26 to the lifting frame 5. This double-sided pin design effectively prevents the third connecting rod 26 from falling off during vibration or tilting, serving as a firm and limiting fixation for the third connecting rod 26. When the third connecting rod 26 needs to be used again, simply pull the pull handle 38 again to disengage the pins 35 from the pin holes 39, and the third connecting rod 26 can be flipped upwards.

[0030] The other end of the pin 35 is tapered; The tapered shape of one end of the pin 35 facilitates its insertion into the pin hole 39. Even if there is a slight misalignment between the pin 35 and the pin hole 39, the tapered surface can act as a guide, allowing the pin 35 to slide smoothly into the pin hole 39.

[0031] The ends of the first lug 24, the third lug 30 and the fourth lug 31 are all provided with reinforcing ribs; The reinforcing ribs can be triangular, trapezoidal, or arc-shaped steel plates, welded to the connection between the lugs and the lifting structure or connecting plate structure. By adding these reinforcing ribs, the load-bearing capacity and fatigue resistance of the first lug 24, the third lug 30, and the fourth lug 31 are effectively increased, stress concentration is reduced, and service life is extended. Especially when lifting large, heavy ship pipe modules, where the lifting load can reach several tons or even tens of tons, the presence of the reinforcing ribs ensures that the lugs will not tear at the root or undergo plastic deformation under extreme loads, thus guaranteeing the safety of the lifting operation.

[0032] In summary, when using this lifting platform for lifting ship pipe modules, if it is necessary to lift small and lightweight ship pipe units, either the main lifting platform 1 or the auxiliary lifting platform 2 can be used alone, depending on the actual situation. The operator connects the lifting cable of the lifting equipment to the first lug 24 on the main lifting platform 1, and then connects the lifting cable from the second lug 25 to the lifting point of the ship pipe module. After confirming that all connections are secure, the pipe unit can be lifted smoothly using the lifting equipment. During this process, the third connecting rod 26 is fixed to the lifting frame 5 by the snap-fit ​​box 32 and the pin 35, without causing interference. When it is necessary to install the first connecting plate 3 on the main lifting frame 1 to lift the pipe unit, First, by simultaneously pulling the two handles 38 inside the inner slide groove 33, the pin 35 is moved into the inner slide groove 33, causing the pin 35 to be completely pulled out from the pin hole 39, thus releasing the restriction on the third connecting rod 26. Then, the third connecting rod 26 is flipped upwards, changing it from a horizontal storage state to a vertical or tilted state. Next, the first connecting plate 3 is hoisted above the main hoisting frame 1, and its position is adjusted so that the first connecting plate 3 is aligned with the frame of the main hoisting frame 1. The third connecting rod 26 is then rotated so that its free end is inserted into the connecting groove in the middle of the mounting base 27 and the connecting base 28, and the hole at its end is aligned with the threaded rod 29. The threaded rod 29 is rotated so that it passes through the hole at the end of the third connecting rod 26 and is threadedly connected to the connecting base 28, thus fixing the third connecting rod 26 in the connecting groove and completing the connection between the first connecting plate 3 and the main hoisting frame 1. To further enhance connection stability, a hoisting cable can be used to connect the first lug 24 and the third lug 30 to form a flexible auxiliary connection. Finally, the hoisting cable of the lifting equipment is connected to the fourth lug 31 on the top of the first connecting plate 3, and the pipe module is hoisted through the combination of the hoisting bar and the connecting plate. When the pipe unit to be hoisted is large in volume and heavy in weight, and a single hoisting bar cannot meet the requirements for bearing area and stability, it is necessary to connect and combine the main hoisting bar 1 and the auxiliary hoisting bar 2 for use. First, following the aforementioned operating method of the connecting mechanism, the main suspension rod 1 and the auxiliary suspension rod 2 are spliced ​​together. Specifically, the first connecting rod 11 on the side of the auxiliary connecting plate 9 at the end of the auxiliary suspension rod 2 is aligned with the connecting hole 8 on the main connecting plate 6, and after being pushed in, the locking plate 15 automatically unfolds and locks, completing the quick connection between the main suspension rod 1 and the auxiliary suspension rod 2. Depending on the shape of the pipe module, end connection or side connection can be selected, and multiple sets of suspension rods can be used for expansion if necessary. Then, following the connection method described above, the second connecting plate 4 is connected above the assembled main hoist 1 and auxiliary hoist 2 to further fix their relative positions and improve overall rigidity. Similarly, the first lug 24 and the third lug 30 can also be connected via lifting cables. Finally, connect the lifting cable of the lifting equipment to the fourth lug 31 at the top of the second connecting plate 4, or simultaneously to the first lug 24 of each lifting block, selecting the optimal combination of lifting points based on the actual stress analysis. After confirming that all connections are secure, safe and stable lifting operations can be carried out on large-volume ship pipe units; After the hoisting operation is completed, the combined structure needs to be disassembled. When disassembling the main hoisting rod 1 and the auxiliary hoisting rod 2, pull the pull plate 22 outwards to retract the locking plate 15, then move the auxiliary hoisting rod 2 laterally out. When disassembling the connecting plate, rotate the threaded rod 29 in the reverse direction to disengage the third connecting rod 26 from the connecting groove, then lift the connecting plate away. Finally, flip the third connecting rod 26 downwards and secure it to the lifting frame 5 using the snap-fit ​​box 32 and the pin 35, completing the storage process.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
