Marine detachable lifting clamps

Abstract

This invention discloses a detachable lifting clamp fixture for ships. It includes a connecting assembly, a driving assembly, and a suspension assembly. The connecting assembly includes a clamping member and a top support member. The clamping member can clamp and fix the web of a pre-shaped profile, and the top support member can abut against the panel of the pre-shaped profile from top to bottom. The driving assembly is connected to the connecting assembly to drive the connecting assembly to clamp and release the web. The suspension assembly is connected to the connecting assembly and is used to install the lifting clamp. Through the clamping member and the top support member, the pre-shaped profile can be detachably fixed in a clamping manner, and the lifting weight can be applied to both the web and the panel simultaneously. Compared with welding the lifting clamp, this avoids welding work, improves lifting efficiency, reduces lifting costs, and reduces damage to the hull structure. Furthermore, by distributing the weight, it reduces the risk of deformation and damage to the hull structure, especially the panel of the pre-shaped profile.

Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a detachable lifting fixture for ships. Background Technology

[0002] During the shipbuilding phase, there are several methods for moving equipment into the ship's hold. One is to position the equipment before the ship sections are hoisted, and the other is to hoist it in after the ship sections are hoisted, using access holes, hatches, or other openings. Regardless of the method used, the equipment needs to be hoisted into the ship's hold; some equipment may need to be moved, while others may require drilling holes in the base for installation. Because aluminum ships have a relatively weak structure, methods such as temporary clamping with hoists or using hook holes generally cause structural damage. Therefore, it is necessary to weld lifting clamps and use them to lift the equipment.

[0003] Existing methods for hoisting equipment inside aluminum ships generally involve first determining the number and welding positions of lifting clamps based on the equipment's weight, distance from the external crane's lowering position, and the actual location. Then, the lifting clamps are assembled and welded to the cabin. Next, flaw detection is performed on the welded areas to ensure the strength and firmness of the welded connections, meeting the load-bearing requirements for hoisting. Finally, hoists are installed on the lifting clamps, and the equipment is hoisted using a swinging motion. After hoisting, the lifting clamps need to be removed, and the welded areas inside the cabin need grinding and repair welding. The entire hoisting process is time-consuming and labor-intensive, and carries a high risk of structural deformation and damage during transport.

[0004] Therefore, there is an urgent need for a detachable marine lifting fixture to solve the above-mentioned technical problems. Summary of the Invention

[0039] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] Furthermore, features specified as "first" or "second" may explicitly or implicitly include one or more of those features, used to distinguish and describe features, without any order or emphasis. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0042] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] The following is for reference. Figures 1 to 15 This invention introduces the detachable marine lifting fixture. For example... Figures 1 to 3 As shown, this detachable marine lifting fixture can install the lifting bracket 4 onto a pre-shaped profile of the hull, thereby applying the weight of the equipment to the pre-shaped profile (including aluminum, steel, etc.) during equipment lifting. Specifically, the pre-shaped profile (hereinafter referred to as "profile" for ease of explanation) includes T-profiles, I-profiles, etc., as long as at least one web and at least one face plate of the profile are connected in an inverted "T" shape, it can be used to install the detachable marine lifting fixture.

[0044] For example, refer to Figures 1 to 3As shown, the marine detachable lifting clamp includes a connecting assembly 1, a driving assembly 2, and a suspension assembly 3. The connecting assembly 1 includes a clamping member 11 and a top support member 12. The clamping member 11 secures the marine detachable lifting clamp to the web of the profile in a clamping manner, while the top support member 12 abuts against the profile's face plate from top to bottom, thus applying the weight during lifting simultaneously to both the web and the face plate. The driving assembly 2 drives the connecting assembly 1 to clamp and release the web, and maintains the connecting assembly 1 and the pre-shaped profile relatively fixed during clamping, preventing the marine detachable lifting clamp from falling. The suspension assembly 3 is connected to the connecting assembly 1 via the driving assembly 2 and can mount a lifting clamp 4, thereby applying the weight borne by the lifting clamp 4 simultaneously to the web and face plate of the profile through the driving assembly 2 and the connecting assembly 1.

[0045] When using this marine detachable lifting fixture, the clamping member 11 and the top support member 12 can be used to easily fix and separate the marine detachable lifting fixture from the profile in a clamping manner. Moreover, during lifting, the weight of the equipment can be applied to the web and the panel of the profile simultaneously. Compared with the welding of the lifting fixture 4 in the prior art, this method avoids the work of welding, flaw detection, cutting, grinding, and repair welding of the lifting fixture 4, improves lifting efficiency, reduces lifting costs, and reduces damage to the hull structure. Furthermore, by distributing the weight, it reduces the risk of deformation and damage to the hull structure, especially the panel of the profile.

[0046] Specifically, refer to Figures 1 to 3 As shown, the clamping member 11 includes a first clamping member 111 and a second clamping member 112. The first clamping member 111 and the second clamping member 112 are tractively connected to the drive assembly 2 and can move towards each other and away from each other under the drive of the drive assembly 2. When the drive assembly 2 drives the first clamping member 111 and the second clamping member 112 to move towards each other, the distance between the first clamping member 111 and the second clamping member 112 decreases until both abut against the web of the profile. At this time, the web can be clamped and fixed between the first clamping member 111 and the second clamping member 112. When it is necessary to insert the web plate between the first clamping member 111 and the second clamping member 112, or when it is necessary to separate the marine detachable lifting fixture from the profile after clamping, so that the web plate is detached from the first clamping member 111 and the second clamping member 112, the drive assembly 2 causes the first clamping member 111 and the second clamping member 112 to move apart, so that the distance between the first clamping member 111 and the second clamping member 112 increases to a value greater than the width of the panel, and the marine detachable lifting fixture can be moved so that the panel and the web plate are detached from the first clamping member 111 and the second clamping member 112.

[0047] Optionally, in this embodiment, the first clamping member 111 and the second clamping member 112 are made of L-shaped steel plates with a thickness of 8mm, a length of 400mm, a width of 100mm, and a height of 100mm. Their relatively large length allows for even weight distribution across the longer web, preventing deformation or damage to the web during lifting. Preferably, a portion of the surface of the first clamping member 111 and the second clamping member 112 is further padded with approximately 2mm of rubber. The length and width of the rubber are slightly larger than the length and height of the L-shaped steel plate. This increases the friction between the clamping member 111 and the web, enhancing the clamping strength, and also provides some protection to the outer surface of the web, preventing scratches, indentations, and other marks during clamping.

[0048] Reference Figure 4 , Figure 5 As shown, the connecting component 1 and the driving component 2 are spaced apart to form a clearance space. This clearance space can accommodate the panel and prevent interference between the panel and part of the structure in the marine detachable lifting fixture when the marine detachable lifting fixture is fixed to the profile, which would otherwise cause damage or deformation to the panel during installation or lifting.

[0049] Continue to refer to Figure 4 , Figure 5 As shown, the top support 12 includes a first top support 121 and a second top support 122. Both the first top support 121 and the second top support 122 are located within the clearance space and connected to the clamping member 11, thereby abutting against the panel from top to bottom. Preferably, in this embodiment, the web is welded to the middle of the panel, the first top support 121 is fixedly connected to the end of the first clamping member 111 near the second clamping member 112, and the second top support 122 is fixedly connected to the end of the second clamping member 112 near the first clamping member 111. When the clamping member 11 clamps and fixes the web, the first top support 121 and the second top support 122 are located on both sides of the web and can abut against the middle of the panel. Through the first top support 121 and the second top support 122, the pressure on the panel can be concentrated at the connection between the panel and the web and symmetrically distributed on both sides of the web. Because this connection point has stronger resistance to deformation compared to the edge of the panel, it can significantly reduce the risk of deformation and damage to the panel edge compared to the method of distributing pressure evenly across the panel, thus avoiding damage to the hull structure and improving the safety of hoisting operations.

[0050] More preferably, such as Figure 5As shown, the first top support 121 and the second top support 122 are provided with a chamfered structure 1211. The chamfered structure 1211 is used to avoid the weld between the web and the panel, preventing damage to the weld from excessive pressure. This ensures the integrity of the profile's appearance and structure, and also ensures the safety of hoisting operations. For example, in this embodiment, the first top support 121 and the second top support 122 are made of aluminum blocks 400mm long, 10mm wide, and 10mm high, with a 400mm*6mm*6mm top corner cut off along their long angle.

[0051] like Figure 6 As shown, in this embodiment, the drive assembly 2 includes a first transmission member 21 and a second transmission member 22. The first transmission member 21 is fixedly connected to the first clamping member 111, and the second transmission member 22 is fixedly connected to the second clamping member 112. The first transmission member 21 and the second transmission member 22 are connected in a driving manner, so that the distance between the first transmission member 21 and the second transmission member 22 is adjustable. When the distance between the first transmission member 21 and the second transmission member 22 decreases, the distance between the first clamping member 111 and the second clamping member 112 also decreases, thereby clamping the web plate. When the distance between the first transmission member 21 and the second transmission member 22 increases, the distance between the first clamping member 111 and the second clamping member 112 also increases, thereby releasing the web plate.

[0052] It should be noted that the first transmission component 21 and the second transmission component 22 can be connected in various ways, such as through hinges, worm gears, racks and pinions, etc. This invention does not impose specific limitations on these methods, as long as clamping and fixing are achieved. Furthermore, the drive assembly 2 can achieve clamping manually, or through electric, pneumatic, or other methods; this invention also does not impose specific limitations on these methods.

[0053] like Figure 6 As shown, specifically in this embodiment, the drive assembly 2 further includes a first bolt 23, a second bolt 24, a first threaded sleeve 25, and a second threaded sleeve 26. The first threaded sleeve 25 is fixedly installed on the first transmission member 21, and the first bolt 23 is rotatably connected to the first transmission member 21, with a limiting arrangement between the first bolt 23 and the first transmission member 21. The second threaded sleeve 26 is fixedly installed on the second transmission member 22, and the second bolt 24 is rotatably connected to the second transmission member 22, with a limiting arrangement between the second bolt 24 and the second transmission member 22. The first bolt 23 and the second threaded sleeve 26 are axially opposite to each other, and the second bolt 24 and the first threaded sleeve 25 are axially opposite to each other.

[0054] When the first clamping member 111 and the second clamping member 112 need to clamp the web plate, the first bolt 23 is inserted into the second threaded sleeve 26, and the second bolt 24 is inserted into the first threaded sleeve 25. The first bolt 23 is rotated in the direction of penetrating the second threaded sleeve 26, and the second bolt 24 is rotated in the direction of penetrating the first threaded sleeve 25. This increases the thread engagement length, causing a change in the axial position between the first bolt 23 and the second threaded sleeve 26, and between the second bolt 24 and the first threaded sleeve 25, thus reducing the distance between the first transmission member 21 and the second transmission member 22, thereby clamping the web plate. Furthermore, when the web plate needs to be released, the first bolt 23 is rotated in the direction of unscrewing the second threaded sleeve 26, and the second bolt 24 is rotated in the direction of unscrewing the first threaded sleeve 25. This decreases the thread engagement length, causing a change in the axial position between the first bolt 23 and the second threaded sleeve 26, and between the second bolt 24 and the first threaded sleeve 25, thus increasing the distance between the first transmission member 21 and the second transmission member 22, thereby releasing the web plate.

[0055] For example, in this embodiment, such as Figure 4 , Figure 6 As shown, both the first transmission component 21 and the second transmission component 22 are welded together using a first steel plate 211 (300mm long, 80mm wide, and 25mm thick) and a second steel plate 212 (300mm long, 30mm wide, and 8mm thick). The first bolt 23 and the second bolt 24 are M16 bolts, and M16 nuts are fixedly installed at a predetermined distance from the nut portion. The second steel plate 212 is positioned between the nut portion and the M16 nut. A first threaded sleeve 25 is installed on the first steel plate 211 of the first transmission component 21, and a second threaded sleeve 26 is installed on the first steel plate 211 of the second transmission component 22.

[0056] When the web plate needs to be clamped, the first bolt 23 and the second bolt 24 are rotated along the direction of penetration into the first threaded sleeve 25 and the second threaded sleeve 26, respectively. The nut abuts against the outer side of the second steel plate 212, thereby pushing the first transmission member 21 and the second transmission member 22 to move towards each other. When the web plate needs to be released, the first bolt 23 and the second bolt 24 are rotated along the direction of unscrewing the threaded sleeve, respectively. The nut abuts against the inner side of the second steel plate 212, thereby pushing the first transmission member 21 and the second transmission member 22 to move away from each other. Optionally, in this embodiment, the first steel plate 211 of the first transmission member 21 and the first steel plate 211 of the second transmission member 22 are both provided with triangular grooves, so that the first transmission member 21 and the second transmission member 22 can be interlocked with each other. Thus, while meeting the strength requirements, the distance between the first clamping member 111 and the second clamping member 112 after locking the first bolt 23 and the second bolt 24 meets the requirements for clamping the web plate.

[0057] like Figure 7 , Figure 8 As shown, the suspension assembly 3 includes a connecting block 31 and a connecting rod 32. The drive assembly 2 is fixedly provided with the connecting block 31, and the connecting rod 32 is adjustablely inserted through the connecting block 31. The connecting rod 32 is used to install the suspension bracket 4. For example, as shown... Figure 7 As shown, multiple connecting blocks 31 are fixedly disposed on the bottom surfaces of the first transmission member 21 and the second transmission member 22, and are provided with through slots 311 that are 16mm wide and 30mm long. Connecting rods 32 are adjustablely inserted into the through slots 311 of the multiple connecting blocks 31, and limiters are provided at both ends of the connecting rods 32 to prevent them from detaching from the connecting blocks 31. Figure 8 As shown, the lifting bracket 4 is made of a steel plate with a thickness of 20mm, a length of 50mm, and a width of 60mm. A through hole is drilled at one end, 15mm from the end face, for the connecting rod 32 to pass through. Optionally, the end face of this end has a chamfer R=5mm to facilitate the rotation of the lifting bracket 4 around the axis of the connecting rod 32. The other end of the lifting bracket 4 is CNC-cut into a semicircle with an approximate diameter of 60mm, and a 40mm diameter hole is cut at the center of the semicircle for suspending hoists, hooks, and other tools.

[0058] Optionally, such as Figure 9 As shown, multiple drive components 2 and connecting components 1 can be connected to the suspension assembly 3 to meet different lifting requirements. Exemplarily, the suspension assembly 3 also includes a connecting beam 33, which is made of 600mm or 1100mm long I-beams and has a channel with a cross-sectional width of 50mm and a thickness of 20mm. Along the length of the connecting beam 33, a drive component 2 is connected to each end of the connecting beam 33, and each drive component 2 is connected to a connecting component 1. Each connecting component 1 is clamped and fixed to the web plate. The lifting bracket 4 is adjustablely installed on the connecting beam 33 along its length, further facilitating the positioning of the lifting bracket 4.

[0059] Specifically, such as Figures 9 to 11As shown, in this embodiment, the suspension assembly 3 further includes a suspension member 34, a bidirectional threaded sleeve 36, a third bolt 35, and a fourth bolt 37. The suspension member 34 is mounted on the connecting rod 32, the third bolt 35 is mounted on the suspension member 34, and the fourth bolt 37 is mounted on the connecting beam 33. The third bolt 35 and the fourth bolt 37 are connected by the bidirectional threaded sleeve 36. Exemplarily, the suspension member 34 includes a steel plate 20mm thick, 50mm long, and 60mm wide. A 16mm through hole is drilled at one end of the steel plate, 15mm from the end face, and the connecting rod 32 is rotatably inserted into the through hole. A bolt mounting plate 60mm long, 50mm wide, and 20mm thick is welded to the other end of the steel plate, and an M20 third bolt 35 is welded to the middle of the bolt mounting plate. The connecting beam 33 is fitted with an M20 fourth bolt 37. The threads of the third bolt 35 and the fourth bolt 37 are opposite. The third bolt 35 is threaded to one end of the double-threaded sleeve 36, and the fourth bolt 37 is threaded to the other end of the double-threaded sleeve 36. Thus, the third bolt 35 and the fourth bolt 37 are conveniently and firmly fixed by the double-threaded sleeve 36.

[0060] More specifically, such as Figures 10 to 12 As shown, in this embodiment, the lifting bracket 4 includes a locking bolt 41, which abuts against the connecting beam 33, thereby fixing the lifting bracket 4 to the connecting beam 33. Exemplarily, the lifting bracket 4 includes a third steel plate 42, a fourth steel plate 43, a fifth steel plate 44, and a sixth steel plate 45 welded together. The sixth steel plate 45 is 20mm thick, 50mm long, and 60mm wide, with one end CNC-cut into a semicircle with an approximate diameter of 60mm. A 40mm diameter hole is cut at the center of the semicircle for suspending tools such as hoists and hooks. The third steel plate 42 is 60mm long, 100mm wide, and 20mm thick; the fourth steel plate 43 is 60mm long, 50mm wide, and 20mm thick; and the fifth steel plate 44 is 60mm long, 20mm wide, and 20mm thick. The bottom surface of the third steel plate 42 is welded to the sixth steel plate 45, and the top surface of the third steel plate 42 has a fourth steel plate 43 welded to each end along its width direction. The fourth steel plate 43 is connected to the third steel plate 42 at one end along its width direction (after connection, due to different orientations, the width direction of the fourth steel plate 43 is perpendicular to the width direction of the third steel plate 42), and to the fifth steel plate 44 at the other end. In this embodiment, a lifting bracket 4 is mainly formed by welding together a third steel plate 42, two fourth steel plates 43, two fifth steel plates 44, and a sixth steel plate 45. A receiving cavity is formed between the third steel plate 42, the fourth steel plate 43, and the fifth steel plate 44, and the connecting beam 33 passes through the receiving cavity. The fifth steel plate 44 can abut against the connecting beam 33 from top to bottom, thereby applying weight to the connecting beam 33.

[0061] like Figure 11 , Figure 12As shown, a nut is welded to the fifth steel plate 44, and the aforementioned locking bolt 41 passes through the nut. By adjusting the connection position of the locking bolt 41 and the nut, the end of the locking bolt 41 can be made to abut or disengage from the connecting beam 33. When the end of the locking bolt 41 abuts against the connecting beam 33, the lifting bracket 4 and the connecting beam 33 are relatively fixed. When the end of the locking bolt 41 disengages from the connecting beam 33, the lifting bracket 4 can slide along the length of the connecting beam 33, thereby adjusting the relative position between the lifting bracket 4 and the connecting beam 33. Optionally, 10mm through holes are provided at both ends of the connecting beam 33, and M10 pins 38 are provided in the through holes to prevent the lifting bracket 4 from disengaging from the connecting beam 33 during sliding.

[0062] By connecting beam 33 and providing at least two drive components 2 and connecting components 1, lifting brackets 4 can be installed between the two sides of a localized location where a suitable web is unavailable. The position of the lifting brackets 4 is adjustable, facilitating installation and enabling multiple supports for leverage, thus reducing the difficulty of lifting. Simultaneously, it avoids stress concentration on a single profile, providing excellent protection for the hull structure.

[0063] Alternatively, in some embodiments, such as Figures 13 to 15 As shown, the lifting bracket 4 includes a rotatably mounted polygonal roller 46. The outer circumference of the polygonal roller 46 rotates from top to bottom and abuts against the connecting beam 33, providing resistance as it rolls along the connecting beam 33. This resistance prevents the lifting bracket 4 from easily slipping and allows it to adjust its position along the length of the connecting beam 33 under a certain traction force. This enables the connecting beam 33 to form a sliding track during lifting, which is safer and more convenient than swinging, and improves the efficiency of translation within a local area.

[0064] Specifically, the lifting bracket 4 includes a seventh steel plate 47, an eighth steel plate 48, a ninth steel plate 49, and a polygonal roller 46. The ninth steel plate 49 is 20mm thick, 50mm long, and 60mm wide. One end is CNC-cut into a semicircle with an approximate diameter of 60mm, and a 40mm diameter hole is cut at the center of the semicircle for suspending hoists, hooks, and other tools. The seventh steel plate 47 is 60mm long, 90mm wide, and 20mm thick, and the eighth steel plate 48 is 60mm long, 50mm wide, and 20mm thick. The bottom surface of the seventh steel plate 47 is welded to the ninth steel plate 49, and the top surface of the seventh steel plate 47 is welded to each end along its width direction with an eighth steel plate 48. The eighth steel plate 48 has a 20mm mounting hole, through which the polygonal roller 46 rotatably passes. Both sides of the mounting hole are drilled and fitted with washers and cotter pins to prevent detachment.

[0065] In this embodiment, a lifting bracket 4 is mainly formed by connecting a seventh steel plate 47, two eighth steel plates 48, a ninth steel plate 49, and four polygonal rollers 46. The two eighth steel plates 48 are located on both sides of the connecting beam 33, and each eighth steel plate 48 is equipped with two polygonal rollers 46 to improve translational stability. Optionally, in this embodiment, the polygonal rollers 46 are machined from cylinders, and the cylindrical surface away from the side plate hole is machined into an octagonal prism with an outer tangent circle of 20mm. The octagonal prism part is used to rotate and abut against the connecting beam 33. Optionally, the lifting bracket 4 is also provided with the aforementioned locking bolts 41, which can play a fixing role, so that the lifting bracket 4 can both translate along the connecting beam 33 and remain relatively fixed to the connecting beam 33.

[0066] In use, first fix the connecting beam 33 to the profile, then attach the lifting bracket 4 to the connecting beam 33. At this point, the locking bolt 41 is pressed against the connecting beam 33 to fix the lifting bracket 4, which serves as a fixed fulcrum for lifting equipment. Alternatively, if the locking bolt 41 is detached from the connecting beam 33 and the lifting bracket 4 is pulled by ropes, the lifting bracket 4 can be used as a movable fulcrum to move the equipment. It can be understood that by setting multiple connecting beams 33 and connecting them together, the lifting bracket 4 can slide between the connecting beams 33, or by changing the fulcrum, tools such as hoists and hooks can be switched between different lifting brackets 4 connected to two different connecting beams 33, thus meeting the needs for long-distance or staggered horizontal lifting. Of course, connecting beams of other shapes, such as U-shaped ones, can also be used to meet the needs for horizontal lifting in different directions.

[0067] For example, a piece of equipment to be lifted has multiple hooks. When the equipment to be lifted is moved between two connecting beams 33, one of the free hooks can be directly hooked to the lifting weight 4 on the connecting beam 33 to be reached, and the original hook can be separated from the original lifting weight 4. This allows for convenient translation without having to put it down and then lift it again.
