Description

Technical Field

[0001] This utility model relates to the field of oil tanker technology, and in particular to a suspended basket platform for oil tankers. Background Technology

[0002] Product tankers (or crude oil product tankers) are waterborne vessels specifically designed for transporting refined petroleum products such as gasoline, diesel, and kerosene. They primarily transport these products from refineries to end users like ports and gas stations, playing a crucial logistical role in the petroleum supply chain. When welding the hull plating of a product tanker, such as the 114,000-ton AFRAMAX crude oil product tanker, a suspended platform is typically used to assist the welders.

[0003] When suspending a suspended platform on the outside of a ship's hull, lifting lugs are typically welded to the deck for suspension. However, this method can cause damage to the paint on the deck's top surface. Furthermore, typical suspended platforms lack adequate fall protection structures, relying solely on protective railings, which poses a significant risk. Therefore, finding a suitable way to suspend a suspended platform without welding lugs, while also providing adequate fall protection for welding workers, are crucial issues that need to be addressed in the design of suspended platforms for product oil tankers. Utility Model Content

[0004] This utility model addresses the problems of suspended basket platforms requiring welding of lifting lugs onto the deck for suspension and lacking adequate fall protection structures by providing a suspended basket platform for product oil tankers.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions: This utility model provides a suspended basket platform for a product oil tanker, including a base plate, and further including: four support legs fixedly connected to the bottom side wall of the base plate, a guardrail and a welding machine box fixedly connected to the top side wall of the base plate, a lifting mechanism fixedly installed at the bottom of the base plate, and a basket platform fixedly installed at the bottom of the lifting mechanism. A fall protection structure is installed on a suspended platform to protect welding workers from falling. The suspension hook is fixedly installed on the back of the base plate; A clamping structure is provided on the suspension hook.

[0006] Preferably, a second guardrail is fixedly connected to the top side wall of the suspended platform, and two anti-fall bars are fixedly connected to the inner side wall of the second guardrail.

[0007] Preferably, four support rollers are fixedly connected to the side walls of the suspended platform and the second guardrail.

[0008] In this technical solution, the support rollers roll along the side wall of the ship's deck as the suspended platform descends.

[0009] Preferably, the fall protection structure includes a protective sleeve, a fall protection rope, a fixing frame, a hook, and a square through slot. One end of the fall protection rope is fixedly connected to the side wall of the protective sleeve, and the other end of the fall protection rope is fixedly connected to the fixing frame. A square through slot is provided on the side wall of the fixing frame, and a hook is rotatably connected to the side wall of the fixing frame. The hook and the square through slot cooperate with each other.

[0010] In this technical solution, the protective gear is worn on the body, the strap is fastened in front of the chest, and the hook is attached to the fall arrest bar, which provides better fall protection for welding workers.

[0011] Preferably, the protective cover consists of a crotch cover, a connecting strap, a connecting rope, and straps. The connecting strap and two connecting ropes are fixedly connected to the side wall of the crotch cover. The connecting strap and the connecting rope are located on both sides of the crotch cover. The other end of the connecting rope is fixedly connected to the side wall of the other end of the connecting strap. Four straps are fixedly connected to the side walls of the two connecting ropes.

[0012] In this technical solution, when wearing the protective gear, both legs are passed through the crotch cover, the connecting strap is placed behind the welder, and the welder's two arms are passed between the connecting rope and the connecting strap, and then the strap is tied tightly in front of the chest.

[0013] Preferably, the fall protection structure includes a rotating handle block, a threaded rod, a connecting block, and a limiting frame. The threaded rod is threadedly connected to the side wall of the fixed frame. One end of the threaded rod is fixedly connected to the rotating handle block, and the other end of the threaded rod is fixedly connected to the connecting block. The limiting frame is rotatably connected to the connecting block, and the limiting frame is slidably connected inside the fixed frame. The limiting frame has a U-shaped structure.

[0014] In this technical solution, the first rotating handle is manually rotated, which drives the first threaded rod to rotate. The rotation of the first threaded rod causes it to move, which in turn drives the connecting block to move. The connecting block then drives the limiting frame to move, so that the limiting frame is engaged between the hook and the side wall of the fixing frame, preventing the hook from detaching from the square through slot and failing to properly hook onto the fall arrest bar.

[0015] Preferably, a ladder is fixedly connected to the front side wall of the base plate.

[0016] In this technical solution, welding workers enter the suspended platform via a ladder.

[0017] Preferably, the clamping structure includes a support frame, a first fixing block, a connecting rod, a second threaded rod, a rotating block, a rotating plate, and a second rotating handle block. The support frame is fixedly connected to the top side wall of the suspension hook. The first fixing block is fixedly connected to the inner side wall of the support frame. A connecting rod is rotatably connected to the side wall of the first fixing block. Two second threaded rods are rotatably connected to both ends of the connecting rod. A rotating block is fixedly connected to the other end of the two second threaded rods. The rotating block is rotatably connected to the side wall of the support frame. The rotating plate is fixedly connected to the end of the rotating block. The second rotating handle block is fixedly connected to the side wall of the rotating plate.

[0018] In this technical solution, the second rotating handle is manually rotated, which drives the rotating plate to rotate, which in turn drives the rotating block to rotate, which in turn drives the threaded rod 2 to rotate, which in turn drives the threaded rod 2 on the other side to rotate via the connecting rod, and the rotation of the two threaded rods 2 drives the moving frame 2 to move.

[0019] Preferably, the threads on the threaded rods on both sides of the connecting rod are opposite to each other, the rotating plate has threaded grooves at equal intervals on its side wall, the threaded grooves are connected to fixing bolts, the support frame has threaded grooves on its side wall, and the threaded grooves and fixing bolts cooperate with each other.

[0020] In this technical solution, the fixing bolts are threaded into threaded groove one and threaded groove two, fixing and restricting the rotating plate, thereby restricting the movement of the clamping frame.

[0021] Preferably, the clamping structure includes a movable frame 1, a clamping frame, a fixed block 2, a push rod, and the movable frame 2. The movable frame 2 is threadedly connected to two threaded rods 2. One end of the push rod is rotatably connected to the side wall of the movable frame 2, and the other end of the push rod is rotatably connected to the fixed block 2. The movable frame 1 is fixedly connected to the side wall of the fixed block 2. The movable frame 1 is slidably connected to the top side wall of the suspension hook. Two clamping frames are fixedly connected to the side wall of the movable frame, and the clamping frames are slidably connected to the side wall of the suspension hook.

[0022] In this technical solution, the movement of the second movable frame drives the movement of the push rod, which in turn drives the movement of the first movable frame, which in turn drives the movement of the clamping frame, so that the clamping frame presses firmly against the side wall of the ship plate, thereby ensuring that the suspension hook is tightly clamped and fixed to the top of the ship plate, preventing the suspension hook from falling off.

[0023] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0024] The positive and progressive effects of this utility model are as follows: 1. By attaching the suspension hook to the top of the ship's deck, the entire suspended platform is suspended on the outside of the deck. This facilitates better suspension of the platform and eliminates the need to weld lifting lugs to the deck, saving the later grinding process and avoiding damage to the deck's paint.

[0025] 2. By manually rotating the second rotating block, the second rotating block drives the second threaded rod to rotate, the second threaded rod drives the second moving frame to move, and the second moving frame drives the clamping frame to move, so that the clamping frame tightly abuts against the side wall of the ship plate, making it easy to firmly clamp and fix the suspension hook to the top of the ship plate and prevent the suspension hook from falling off.

[0026] 3. Welders entering the suspended platform shall wear protective gear, fasten the straps in front of their chests, and hook the hooks onto the fall arrest bar to better protect them from falling.

[0027] 4. The end of the hook in this application passes through the square through slot and the limiting frame. The rotating handle is manually rotated. The rotating handle drives the threaded rod to rotate. The rotation of the threaded rod causes it to move. The movement of the threaded rod causes the connecting block to move. The connecting block causes the limiting frame to move, so that the limiting frame is engaged between the side wall of the hook and the fixed frame. This helps to prevent the hook from coming out of the square through slot and being unable to hook onto the fall arrest bar properly. Attached Figure Description

[0037] like Figure 1-7 As shown, the suspended platform for a product oil tanker includes a base plate 2, and further includes: four support legs 1 fixedly connected to the bottom side wall of the base plate 2, a guardrail 3 and a welding machine box 4 fixedly connected to the top side wall of the base plate 2, a lifting mechanism 5 fixedly installed at the bottom of the base plate 2, and a suspended platform 6 fixedly installed at the bottom of the lifting mechanism 5. A fall protection structure 10 is installed on the suspended platform 6 to protect welding workers from falling. The suspension hook 11 is fixedly installed on the back of the base plate 2; A clamping structure 13 is provided on the suspension hook 11.

[0038] A second guardrail 8 is fixedly connected to the top side wall of the suspended platform 6, and two anti-fall bars 14 are fixedly connected to the inner side wall of the second guardrail 8.

[0039] Four supporting rollers 12 are fixedly connected to the side walls of the suspended platform 6 and the guardrail 8.

[0040] As the suspended platform 6 descends, the support rollers 12 roll along the side wall of the ship's deck.

[0041] The fall protection structure 10 includes a protective sleeve 1001, a fall protection rope 1002, a fixing frame 1003, a hook 1004, and a square through groove 1005. One end of the fall protection rope 1002 is fixedly connected to the side wall of the protective sleeve 1001, and the other end of the fall protection rope 1002 is fixedly connected to the fixing frame 1003. A square through groove 1005 is provided on the side wall of the fixing frame 1003, and the hook 1004 is rotatably connected to the side wall of the fixing frame 1003. The hook 1004 and the square through groove 1005 cooperate with each other.

[0042] Wearing the protective gear 1001 and fastening the strap 1024 in front of the chest, and hooking the hook 1004 onto the fall arrest bar 14, the welder is better protected from falling.

[0043] The protective cover 1001 consists of a crotch cover 1021, a connecting strap 1022, a connecting rope 1023, and straps 1024. The connecting strap 1022 and two connecting ropes 1023 are fixedly connected to the side wall of the crotch cover 1021. The connecting strap 1022 and the connecting ropes 1023 are located on both sides of the crotch cover 1021. The other end of the connecting rope 1023 is fixedly connected to the side wall of the other end of the connecting strap 1022. Four straps 1024 are fixedly connected to the side walls of the two connecting ropes 1023.

[0044] When putting on the protective cover 1001, the two legs are put through the crotch cover 1021, the connecting strap 1022 is placed behind the welder, the welder's two arms are put through the connecting rope 1023 and the connecting strap 1022 respectively, and then the strap 1024 is tied tightly in front of the chest.

[0045] The fall arrestor structure 10 includes a rotating handle block 1011, a threaded rod 1012, a connecting block 1013, and a limiting frame 1014. The threaded rod 1012 is threadedly connected to the side wall of the fixed frame 1003. One end of the threaded rod 1012 is fixedly connected to the rotating handle block 1011, and the other end of the threaded rod 1012 is fixedly connected to the connecting block 1013. The limiting frame 1014 is rotatably connected to the connecting block 1013. The limiting frame 1014 is slidably connected within the fixed frame 1003 and has a U-shaped structure.

[0046] Manually rotate the rotating handle 1011. Rotating the handle 1011 causes the threaded rod 1012 to rotate. The rotation of the threaded rod 1012 causes it to move. The movement of the threaded rod 1012 causes the connecting block 1013 to move. The connecting block 1013 causes the limiting frame 1014 to move, so that the limiting frame 1014 is engaged between the hook 1004 and the side wall of the fixing frame 1003, preventing the hook 1004 from disengaging from the square through slot 1005 and failing to hook properly onto the fall arrestor 14.

[0047] A ladder 7 is fixedly connected to the front side wall of the base plate 2.

[0048] Welders climb ladder 7 to access the suspended platform 6.

[0049] The clamping structure 13 includes a support frame 1301, a fixing block 1302, a connecting rod 1303, a threaded rod 1304, a rotating block 1305, a rotating plate 1306, and a rotating handle block 1307. The support frame 1301 is fixedly connected to the top side wall of the suspension hook 11. The fixing block 1302 is fixedly connected to the inner side wall of the support frame 1301. The connecting rod 1303 is rotatably connected to the side wall of the fixing block 1302. Two threaded rods 1304 are rotatably connected to both ends of the connecting rod 1303. The other ends of the two threaded rods 1304 are fixedly connected to the rotating block 1305. The rotating block 1305 is rotatably connected to the side wall of the support frame 1301. The rotating plate 1306 is fixedly connected to the end of the rotating block 1305. The rotating handle block 1307 is fixedly connected to the side wall of the rotating plate 1306.

[0050] Manually rotate the second rotating block 1307, which drives the rotating plate 1306 to rotate. The rotating plate 1306 drives the rotating block 1305 to rotate, which drives the threaded rod 1304 to rotate. The threaded rod 1304 drives the other threaded rod 1304 to rotate through the connecting rod 1303. The rotation of the two threaded rods 1304 drives the moving frame 1315 to move.

[0051] The threads on the threaded rods 1304 on both sides of the connecting rod 1303 are opposite to each other. The rotating plate 1306 has threaded grooves 1321 at equal intervals on its side wall. The threaded grooves 1321 are threaded with fixing bolts 1323. The support frame 1301 has threaded grooves 1322 on its side wall. The threaded grooves 1322 and fixing bolts 1323 cooperate with each other.

[0052] The fixing bolt 1323 is threaded into the first threaded groove 1321 and the second threaded groove 1322, fixing and restricting the rotating plate 1306, thereby restricting the movement of the clamping frame 1312.

[0053] The clamping structure 13 includes a movable frame 1311, a clamping frame 1312, a fixed block 1313, a push rod 1314, and a movable frame 1315. The movable frame 1315 is threadedly connected to two threaded rods 1304. One end of the push rod 1314 is rotatably connected to the side wall of the movable frame 1315, and the other end of the push rod 1314 is rotatably connected to the fixed block 1313. The movable frame 1311 is fixedly connected to the side wall of the fixed block 1313. The movable frame 1311 is slidably connected to the top side wall of the suspension hook 11. Two clamping frames 1312 are fixedly connected to the side wall of the movable frame, and the clamping frames 1312 are slidably connected to the side wall of the suspension hook 11.

[0054] The movement of the second movable frame 1315 drives the movement of the push rod 1314, which in turn drives the movement of the first movable frame 1311. The first movable frame 1311 then drives the movement of the clamping frame 1312, which in turn presses the clamping frame 1312 firmly against the side wall of the ship plate, thereby clamping the suspension hook 11 tightly to the top of the ship plate and preventing the suspension hook 11 from falling off.

[0055] When this utility model is in use, the electrical components mentioned in this application are all connected to an external power supply and control switch. When welding the hull plate, the suspension hook 11 is hooked on the top of the hull plate, so that the entire suspension basket platform 6 is suspended on the outside of the hull plate. This eliminates the need to weld lifting lugs to the deck, saves the later grinding process, and avoids the burning of the top paint on the deck. Manually rotate the second rotating block 1307, which drives the rotating plate 1306 to rotate. The rotating plate 1306 drives the rotating block 1305 to rotate. The rotating block 1305 drives the second threaded rod 1304 to rotate. The second threaded rod 1304 drives the other threaded rod 1304 to rotate through the connecting rod 1303. The rotation of the two threaded rods 1304 drives the second moving frame 1315 to move. The movement of the second moving frame 1315 drives the push rod 1314 to move. The push rod 1314 drives the first moving frame 1311 to move. The first moving frame 1311 drives the clamping frame 1312 to move, so that the clamping frame 1312 tightly abuts against the side wall of the ship plate, thereby making the suspension hook 11 tightly clamped and fixed to the top of the ship plate, preventing the suspension hook 11 from falling off. Welders climb ladder 7 to enter the suspended platform 6. Once on the platform 6, they put on protective gear 1001, fasten straps 1024 around their chests, and hook hooks 1004 onto the fall arrestor bar 14 for better fall protection. The end of hook 1004 passes through square slot 1005 and restraint frame 1014. Then, they manually rotate the rotating handle 1011, which rotates the threaded rod 1012. The rotation of threaded rod 1012 causes it to move, which in turn moves connecting block 1013. Connecting block 1013 then moves restraint frame 1014, causing restraint frame 1014 to engage between hook 1004 and the side wall of the fixing frame 1003. This prevents hook 1004 from detaching from square slot 1005 and being properly hooked onto fall arrestor bar 14.

[0056] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
