[0002] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art. At present, in the process of semi-submersible cargo transportation, in order to effectively tie and secure the cargo and prevent the cargo from slipping and overturning during transportation, some standard reinforcements are set on the deck of the semi-submersible ship for fixing. Due to the limited precision of floating loading, the standard reinforcements are usually welded and installed on board after the cargo is floated. After the transportation is completed, since the standard reinforcements usually affect the floating unloading operation, the standard reinforcements need to be removed before floating unloading. The above operation process takes a long time to construct, and welding and cutting operations are required during the floating loading and unloading of the semi-submersible ship. Summary of the invention

[0003] The present invention aims to solve at least one of the above-mentioned technical problems in the prior art to a certain extent. To this end, an embodiment of the present invention provides a wedge-shaped reinforcement member for automatic floating loading and unloading of a semi-submersible vessel, which reduces the construction time of floating loading and unloading of the semi-submersible vessel, avoids welding work after floating loading, and avoids cutting work before floating unloading.

[0004] According to an embodiment of the present invention, a semi-submersible ship automatic floating loading and unloading wedge reinforcement comprises a suspension rigging; a wedge block connected to the lower end of the suspension rigging, the wedge block having a first wedge surface, the first wedge surface facing obliquely downward, and the first wedge surface being provided with at least one first opening; a fixed base, the fixed base having a second wedge surface matching the first wedge surface, the second wedge surface facing obliquely upward, and the second wedge surface being provided with at least one second opening; and at least one locking screw, which comprises a double-headed threaded rod and two claw nuts respectively installed at both ends of the double-headed threaded rod, the two claw nuts both having locking claws, the locking claw of one of the claw nuts being clamped into the first opening, and the locking claw of the other claw nut being clamped into the second opening, and the two claw nuts being brought closer to each other or moved away from each other by rotating the double-headed threaded rod, thereby locking or unlocking the wedge block and the fixed base.

[0007] In an optional or preferred embodiment, a plurality of rotating protrusions are provided in the middle of the double-start threaded rod, and the locking screw comprises a handle, and an end of the handle has an inner hole for the rotating protrusion to be inserted into.

[0008] In an optional or preferred embodiment, two locking screws are provided, and the two locking screws share one handle.

[0009] In an optional or preferred embodiment, the first opening is located above the second opening, the lower end of the double-headed threaded rod passes through the fixed base, the first wedge surface of the wedge block is arranged with a first through hole, and the locking claw in the claw nut connected to the lower end of the double-headed threaded rod passes through the second opening and is inserted into the first through hole.

[0010] In an optional or preferred embodiment, the fixed base includes a top sealing plate, and the top sealing plate is provided with a second through hole for the double-start threaded rod to pass through.

[0011] In an optional or preferred embodiment, the first wedge-shaped surface is arranged on the outside of the wedge-shaped block, and an anti-collision wooden board is installed on the inside of the wedge-shaped block.

[0014] Based on the above technical scheme, the embodiment of the present invention has at least the following beneficial effects: by designing a fixed base and a wedge block, the second wedge of the fixed base and the first wedge surface of the wedge block are matched. When floating loading is carried out, according to the arrangement of the cargo, the fixed base can be pre-welded on the lifting deck of the semi-submersible vessel, and then floated up. After the cargo falls into place, the wedge block and the suspension rigging are installed on the cargo, and then the two locking claws of the locking screw are respectively inserted into the second opening of the fixed base and the first opening of the wedge block, and the double-headed threaded rod is rotated to make the two locking claws approach each other, thereby locking the fixed base and the wedge block, and the cargo can be fixed on the semi-submersible vessel; when floating unloading is carried out, the double-headed threaded rod is rotated to make the two locking claws move away from each other, the locking screw is removed, the semi-submersible vessel sinks, and the wedge block enters the water with the cargo. Under the action of buoyancy, the wedge block and the base are separated to achieve floating unloading. By using the present invention, during navigation, the semi-submersible ship's automatic floating loading and unloading wedge-shaped reinforcement piece can not only effectively prevent the cargo from slipping, but also prevent the cargo from turning over, thereby reducing the construction time of the semi-submersible ship's floating loading and unloading, avoiding welding work after floating loading, and avoiding cutting work before floating unloading.

[0038] Figure 1 What is shown is an installation diagram of a standard reinforcement piece 13 used in the floating and unloading process of a semi-submersible vessel in the prior art. After the transportation is completed, since the standard reinforcement piece 13 affects the floating and unloading operation, the standard reinforcement piece 13 needs to be removed before the floating and unloading. The above operation process takes a long time to construct, and welding and cutting operations are involved in the floating and unloading process of the semi-submersible vessel 11.

[0039] Reference Figures 2 to 13 , a semi-submersible ship automatic floating loading and unloading wedge-shaped reinforcement, comprising a suspension rigging 20, a wedge-shaped block 30, a fixed base 50 and two locking screws 40. Figure 2 As shown, both sides of the cargo 12 are installed with wedge-shaped reinforcements for automatic floating loading and unloading of semi-submersible vessels.

[0040] Reference Figure 4 Specifically, the suspension rigging 20 includes a first eye plate 24 for mounting on the cargo 12, a second eye plate 25 for mounting on the wedge block 30, and a connecting rope connecting the first eye plate 24 and the second eye plate 25. Further, the connecting rope includes a steel wire rope 21 and a rigging turnbuckle 22 connected to the steel wire rope 21, the steel wire rope 21 is connected to the first eye plate 24 through a shackle 23, and the rigging turnbuckle 22 is connected to the second eye plate 25 through the shackle 23.

[0041] Combination Figures 5 to 7The wedge block 30 is connected to the lower end of the suspension rigging 20, specifically, the second eye plate 25 is welded to the top of the wedge block 30, and the rigging turn buckle 22 is connected to the second eye plate 25 through the shackle 23. In addition, the wedge block 30 has a first wedge surface 31, which is arranged outside the wedge block 30, facing obliquely downward, and the first wedge surface 31 is provided with at least one first opening 32. In this embodiment, as Figure 6 As shown, the first wedge surface 31 has two first openings 32 .

[0042] Combination Figures 11 to 13 The fixed base 50 has a second wedge surface 51 that matches the first wedge surface 31. The second wedge surface 51 faces obliquely upward and is provided with at least one second opening 52. Fig.12 As shown, the second wedge surface 51 has two second openings 52 in total.

[0043] Combination Figures 8 to 10 The locking screw 40 includes a double-threaded rod 41 and two claw nuts 42 respectively mounted at both ends of the double-threaded rod 41. The two claw nuts 42 both have locking claws 421. The locking claw 421 of one claw nut 42 is inserted into the first opening 32, and the locking claw 421 of the other claw nut 42 is inserted into the second opening 52. The two claw nuts 42 move toward each other or away from each other by rotating the double-threaded rod 41, thereby locking or unlocking the wedge block 30 and the fixed base 50. In this embodiment, each semi-submersible ship automatic floating loading and unloading wedge reinforcement member includes two locking screws 40. Therefore, two first openings 32 of the first wedge surface 31 are provided for the corresponding locking claws 421 to be inserted; and two second openings 52 of the second wedge surface 51 are provided for the locking claws 421 to be inserted. Of course, in some other embodiments, only one locking screw 40 may be provided, with the first opening being horizontally centered and the second opening being horizontally centered, but the locking effect is not as good as that of two locking screws.

[0044] like Fig.14 As shown, before floating, according to the arrangement of the cargo 12, the fixed base 50 can be pre-welded on the lifting deck of the semi-submersible vessel 11, and then floated. Fig.15 As shown, after the cargo 12 is dropped into place, the wedge block 30 and the suspension rigging 20 are installed on the cargo 12. Prior to this, the first eye plate 24 needs to be installed at the upper edge of the side of the cargo 12, and then the two locking claws 421 of the locking screw 40 are respectively inserted into the second opening 52 of the fixed base 50 and the first opening 32 of the wedge block 30, and the double-headed threaded rod 41 is rotated to make the two locking claws 421 approach each other, thereby locking the fixed base 50 and the wedge block 30, and the cargo 12 can be fixed on the semi-submersible vessel 11. When the wedge block 30 and the fixed base 50 are locked, the first wedge surface 31 and the second wedge surface 51 are tightly attached.

[0045] Specifically, if Figure 8 As shown, the threads at both ends of the double-threaded rod 41 are respectively forward-spinning and reverse-spinning, and the locking claws 421 of the two claw nuts 42 are arranged opposite to each other, that is, the two locking claws 421 are directly opposite to each other. A plurality of rotating protrusions 44 are arranged in the middle of the double-threaded rod 41, and the locking screw 40 includes a handle 43. The end of the handle 43 has an inner hole for the rotating protrusion 44 to be inserted into. It can be understood that by inserting a suitable rotating protrusion 44 into the inner hole of the handle 43 and rotating the double-threaded rod 41, the two locking claws 421 can be moved closer to each other, and the specific rotation direction can be set accordingly during the design. In addition, there are two locking screws 40 in this embodiment, and the two locking screws 40 share one handle 43. Of course, if Figure 2 As shown, this floating installation requires two semi-submersible vessels to automatically float and unload wedge-shaped reinforcement members, that is, there are four locking screws 40, and a handle 43 can also be shared.

[0046] Combination Figure 3 When the two locking claws 421 approach each other, the wedge block 30 moves obliquely downward inward to tighten the suspension rigging 20 connected to the cargo 12, and the cargo 12 is clamped inside the wedge block 30. Preferably, an anti-collision board 34 is installed inside the wedge block 30, and the anti-collision board 34 is fastened to the inside of the wedge block 30 by bolts. The semi-submersible ship automatic floating loading and unloading wedge reinforcement member of the embodiment of the present invention can effectively prevent the cargo from slipping during navigation, and can also prevent the cargo from turning over.

[0047] like Fig.16 When performing floating unloading, the double-threaded rod 41 is rotated to move the two locking claws 421 away from each other, and the locking screw 40 is removed. Fig.17 , the semi-submersible vessel 11 sinks, and the wedge-shaped block 30 enters the water together with the cargo 12. Under the action of buoyancy, the wedge-shaped block 30 and the base 50 are separated to achieve floating unloading.

[0048] The embodiments of the present invention can reduce the construction time of floating loading and floating unloading of a semi-submersible vessel, avoid welding work after floating loading, and avoid cutting work before floating unloading.

[0049] Preferably, the first opening 32 is located above the second opening 52, the lower end of the double-threaded rod 41 passes through the fixed base 50, the first wedge surface 31 of the wedge block 30 is arranged with a first through hole 33, and the locking claw 421 in the claw nut 42 connected to the lower end of the double-threaded rod 41 passes through the second opening 52 and is inserted into the first through hole 33. Further, the fixed base 50 includes a top cover plate, and the top cover plate is provided with a second through hole 53 for the double-threaded rod 41 to pass through. It should be noted that the first through hole 33 is further preferably designed according to the specific structure of the wedge block 30, and the second through hole 53 is further preferably designed according to the specific structure of the fixed base 50. Those skilled in the art can adjust the structural mode of the wedge block 30 and the fixed base 50 accordingly, without the need to design the first through hole 33 or the second through hole 53 separately.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
