Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and in particular to a hatch cover and a ship. Background Technology

[0002] In ships equipped with storage rooms, a lifting port is usually installed above the storage room to facilitate the entry and exit of goods. A hatch cover is also installed on the lifting port. At the same time, a crane with appropriate lifting capacity is provided according to the type of goods to lift and transport the goods.

[0003] For small vessels, the cargo stored in the storage compartments is usually small in volume and light in weight, so cargo can be transferred without the need for cranes. Furthermore, some vessels omit cranes altogether to reduce overall weight and save costs. Therefore, in both of these cases, cargo transportation requires manual handling, which is not only inefficient but also a significant waste of human and material resources.

[0004] Therefore, there is an urgent need for a hatch cover and a vessel to solve the above problems. Summary of the Invention

[0005] One objective of this invention is to provide a hatch cover with a simple structure and lifting capability, which eliminates the need for a crane, thus facilitating ship lightweighting. It also eliminates the need for manual cargo handling, resulting in high transportation efficiency and effective labor savings.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Hatch covers, including:

[0008] The hatch body is rotatably connected to the hull to close or open the hatch of the hull;

[0009] The boom includes a support rod portion and a lifting rod portion connected at an angle, the support rod portion being rotatably connected to the hatch body, and the lifting rod portion being equipped with a lifting ring;

[0010] When the hatch cover is closed on the hatch opening, the boom rests against the surface of the hatch cover that is away from the hull.

[0011] When the hatch body opens the hatch, the support rod rotates, which can cause the hoisting rod to flip so that the vertical projection of the hoisting ring is located inside the hatch.

[0012] Optionally, it also includes a first locking mechanism, which includes a positioning seat and a first connecting member. The positioning seat is disposed on the upper surface of the hatch body, and a first through hole is formed on the positioning seat. A second through hole is formed radially through the boom. When the boom is attached to the hatch body, the first connecting member passes through the first through hole and the second through hole in sequence.

[0013] Optionally, multiple second through holes are provided, and the multiple second through holes are spaced apart along the extension direction of the lifting rod on the support rod portion and the lifting rod portion, and multiple positioning seats and the first connecting member are provided accordingly.

[0014] Optionally, the system further includes a flip-connecting mechanism, which includes a connecting seat, a connecting pin, a first hinge plate, and a second hinge plate. The connecting seat is rotatably connected to the hatch body about its own axis. The axis of the connecting seat is spaced apart from and parallel to the upper surface of the hatch body. One end of the first hinge plate and one end of the second hinge plate are rotatably connected by the connecting pin. The other end of the first hinge plate is connected to the connecting seat, and the other end of the second hinge plate is connected to the hoisting rod. The first hinge plate and the second hinge plate rotate about the connecting pin, which can cause the hoisting rod to flip relative to the connecting seat, so that the axis of the support rod is parallel to or coincides with the axis of the connecting seat.

[0015] Optionally, when the axis of the support rod coincides with the axis of the connecting seat, the support rod abuts against the connecting seat.

[0016] Optionally, the flip-connecting mechanism further includes a first fixed seat, a second fixed seat, and a positioning sleeve. The first fixed seat and the second fixed seat are spaced apart on the hatch body along the axial direction of the connecting seat. A rotating connecting hole is provided on the second fixed seat. The positioning sleeve is fixedly connected to the side of the first fixed seat facing the second fixed seat and is coaxially arranged with the rotating connecting hole. The connecting seat is rotatably passed through the rotating connecting hole and sleeved on the positioning sleeve.

[0017] Optionally, it also includes a second locking mechanism, the second locking mechanism including a second connector that can radially connect the connecting seat and the positioning sleeve.

[0018] Optionally, the flipping connection mechanism further includes a lubricant for injecting lubricating oil between the connecting seat and the positioning sleeve.

[0019] Optionally, a weighted rod is fixedly installed on one side of the hatch body, and a first hinge block is provided on the edge of the end face of the hatch body near the weighted rod. The first hinge block is hinged to a second hinge block, and the second hinge block is fixed to the outer wall of the hatch. The hatch cover also includes a support mechanism, which is connected between the hatch body and the inner wall of the hatch, and is used to support the hatch body when the hatch body opens the hatch.

[0020] Another object of the present invention is to provide a ship, including a hull and the above-mentioned hatch cover, wherein a storage compartment is provided in the hull, the storage compartment has a hatch, and the hatch cover body is rotatably connected to the hull, capable of closing or opening the hatch.

[0021] The beneficial effects of this invention are:

[0022] The hatch cover provided by this invention is rotatably connected to the hull to close or open the hatch, thereby sealing the hatch. The boom includes a support rod and a lifting rod connected at an angle. The support rod is rotatably connected to the hatch cover, and a lifting ring is mounted on the lifting rod. When the hatch cover is closed to the hatch, the boom rests against the surface of the hatch cover facing away from the hull, allowing the boom to be laid flat on the hatch cover for storage. When the hatch is opened, the support rod rotates, causing the lifting rod to flip so that the vertical projection of the lifting ring is inside the hatch, facing the hatch, facilitating cargo handling by operators using the lifting ring. This hatch cover can be used to lift cargo by simply rotating the support rod and flipping the lifting rod when cargo needs to be moved. When lifting is not needed, the lifting rod can be stored on the hatch cover body. The overall structure is simple and easy to operate. No crane is required, which helps to achieve the weight reduction of ships. At the same time, no manual cargo handling is required, resulting in high transportation efficiency and effective saving of manpower. Attached Figure Description

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] This embodiment provides a hatch cover with lifting capabilities, enabling cargo lifting without the need for a crane. This facilitates ship weight reduction, increases transportation efficiency, and effectively saves manpower. Figure 1 As shown, the hatch cover includes a hatch cover body 1 and a boom 2.

[0046] The hatch cover body 1 is rotatably connected to the hull 100 to close or open the hatch 101 of the hull 100, thus sealing the hatch 101. The boom 2 includes a support rod portion 21 and a lifting rod portion 22 connected at an angle. The support rod portion 21 is rotatably connected to the hatch cover body 1, and a lifting ring 23 is mounted on the lifting rod portion 22. When the hatch cover body 1 is closed over the hatch 101, the boom 2 rests against the surface of the hatch cover body 1 facing away from the hull 100, allowing the boom 2 to be laid flat on the hatch cover body 1 for storage. When the hatch cover body 1 opens the hatch 101, the support rod portion 21 rotates, causing the lifting rod portion 22 to flip so that the vertical projection of the lifting ring 23 is located inside the hatch 101, facing the hatch 101, facilitating cargo handling by operators using the lifting ring 23. When cargo needs to be moved, the hatch cover can be used to lift the boom 2 by simply rotating the support rod 21 and flipping the lifting rod 22. When lifting is not needed, the boom 2 can be stored on the hatch cover body 1. The overall structure is simple and easy to operate.

[0047] In this embodiment, the lifting rod 22 and the support rod 21 are arranged perpendicularly, and a liner 25 is provided at the connection between the lifting rod 22 and the support rod 21 to improve the overall structural strength of the lifting rod 2.

[0048] Continue to refer to Figure 1 When the hatch cover body 1 is closed on the hatch 101, in order to ensure that the boom 2 is firmly placed on the hatch cover body 1, the hatch cover also includes a first locking mechanism 3.

[0049] Specifically, the first locking mechanism 3 includes a positioning seat 31 and a first connecting member 32. The positioning seat 31 is disposed on the upper surface of the hatch body 1, and a first through hole is formed on the positioning seat 31. A second through hole 24 is formed radially through the boom 2. When the boom 2 is against the hatch body 1, the first connecting member 32 passes through the first through hole and the second through hole 24 in sequence, thereby realizing a reliable connection between the boom 2 and the hatch body 1. In this embodiment, two positioning seats 31 are provided, and the two positioning seats 31 are spaced apart. The distance between the two positioning seats 31 is slightly larger than the diameter of the boom 2. The boom 2 is placed between the two positioning seats 31 to perform initial positioning of the boom 2. Then, the first connecting member 32 connects one positioning seat 31, the boom 2 and the other positioning seat 31 in sequence to further fix the boom 2.

[0050] More specifically, the first locking mechanism 3 also includes a first nut 33. The first connecting member 32 is preferably a bolt, with the bolt shank passing sequentially through a positioning seat 31, the lifting rod 2, and another positioning seat 31. The first nut 33 is screwed onto the portion of the bolt shank that extends out of the other positioning seat 31 to improve the reliability of the connection. In this embodiment, the first nut 33 is a wing nut for ease of operation.

[0051] More specifically, multiple second through holes 24 are provided, and these multiple second through holes 24 are spaced apart along the extension direction of the boom 2 on the support rod portion 21 and the lifting rod portion 22. Multiple positioning seats 31 and first connecting members 32 are correspondingly provided. By providing multiple first locking mechanisms 3 between the boom 2 and the hatch body 1, the reliability of the boom 2 when fixed is ensured.

[0052] like Figure 1 , Figures 3-5 As shown, the hatch cover also includes a flip-up connecting mechanism 4. The flip-up connecting mechanism 4 includes a connecting seat 41, a connecting pin 42, a first hinge plate 43, and a second hinge plate 44. The connecting seat 41 is rotatably connected to the hatch cover body 1 about its own axis. The axis of the connecting seat 41 is spaced apart from and parallel to the upper surface of the hatch cover body 1. One end of the first hinge plate 43 and one end of the second hinge plate 44 are rotatably connected via the connecting pin 42. The other end of the first hinge plate 43 is connected to the connecting seat 41, and the other end of the second hinge plate 44 is connected to the lifting rod portion 22. The rotation of the first hinge plate 43 and the second hinge plate 44 about the connecting pin 42 can cause the lifting rod portion 22 to flip relative to the connecting seat 41, so that the axis of the support rod portion 21 is parallel to or coincides with the axis of the connecting seat 41.

[0053] In other words, after opening the hatch body 1, when the boom 2 needs to be used, firstly, the first locking mechanism 3 is unlocked; then, the connecting seat 41 is controlled to rotate around its own axis, thereby causing the boom 2 to rotate and move away from the hatch body 1. When the axis of the lifting rod 22 of the boom 2 is perpendicular to the hatch body 1, the first hinge plate 43 is rotated so that the axis of the support rod 21 coincides with the connecting seat 41, completing the "erecting" of the boom 2 relative to the hatch body 1. See details below. Figure 4 At this point, the goods can be lifted and transported using the lifting ring 23.

[0054] Preferably, the support rod 21 abuts against the connecting seat 41 when the axis of the support rod 21 coincides with the axis of the connecting seat 41. This arrangement allows the connecting seat 41 to provide support for the support rod 21, ensuring the stability of the boom 2 when lifting goods.

[0055] Specifically, such as Figure 5As shown, the flip-connecting mechanism 4 also includes a first fixed seat 45, a second fixed seat 46, and a positioning sleeve 47. The first fixed seat 45 and the second fixed seat 46 are spaced apart on the hatch body 1 along the axial direction of the connecting seat 41, and a rotating connection hole is formed on the second fixed seat 46. The positioning sleeve 47 is fixed to the side of the first fixed seat 45 facing the second fixed seat 46 and is coaxially arranged with the rotating connection hole. The connecting seat 41 rotatably passes through the rotating connection hole and is sleeved on the positioning sleeve 47. The first fixed seat 45 and the second fixed seat 46 can support the connecting seat 41, and the positioning sleeve 47 is used to limit the rotation direction of the connecting seat 41.

[0056] Furthermore, the flipping connection mechanism 4 also includes a lubricant. The lubricant is used to inject lubricating oil between the connecting seat 41 and the positioning sleeve 47 to improve the smoothness of rotation of the connecting seat 41. The lubricant can be a straight-through pressure injection cup as used in the prior art.

[0057] More specifically, the tilting connection mechanism 4 also includes a safety support structure. A support block 461 is provided on the side of the second fixed seat 46 near the hatch 101, and a connecting plate 26 is provided on the support rod portion 21. When the axis of the support rod portion 21 coincides with the axis of the connecting seat 41, the connecting plate 26 abuts against the support block 461. The support block 461 can support the support rod portion 21, preventing it from tipping over during hoisting and improving safety.

[0058] Preferably, in order to ensure the reliability of the connection between the support block 461 and the connecting plate 26, when the connecting plate 26 and the support block 461 abut, the connecting plate 26 and the support block 461 are fixedly connected by fasteners.

[0059] Optionally, such as Figure 1 As shown, the hatch cover also includes a second locking mechanism 5. The second locking mechanism 5 includes a second connector 51, which radially connects the connecting seat 41 and the positioning sleeve 47. This arrangement prevents the connecting seat 41 from rotating during cargo hoisting, improving safety during use.

[0060] Specifically, the second locking mechanism 5 further includes a second nut 52. The second connector 51 is preferably a bolt, with the bolt shank passing radially through the connector 41 and the positioning sleeve 47. The second nut 52 is screwed onto the portion of the bolt shank that extends out of the connector 41 to improve connection reliability. In this embodiment, the second nut 52 is a wing nut for ease of operation.

[0061] like Figure 2 and Figure 3As shown, a weighted rod 11 is fixedly installed on one side of the hatch body 1. A first hinge block 12 is provided on the edge of the end face of the hatch body 1 near the weighted rod 11. The first hinge block 12 is hinged to a second hinge block 13, which is fixed to the outer wall of the hatch 101. The hatch cover also includes a support mechanism 6, which is connected between the hatch body 1 and the inner wall of the hatch 101, and is used to support the hatch body 1 when the hatch 101 is opened.

[0062] Specifically, the support mechanism 6 includes a support plate 61, a strut 62, and a support base 63. The support plate 61 is disposed on the side of the hatch body 1 facing the hatch 101, and the support base 63 is disposed on the inner wall of the hatch 101. One end of the strut 62 is rotatably connected to the support plate 61, and the other end can slide relative to the inner wall of the hatch 101. The strut 62 has a latch on the side facing the support base 63. When the hatch body 1 rotates to be perpendicular to the plane of the hatch 101, the latch of the strut 62 engages with the support base 63 to support the hatch body 1. Of course, in other embodiments, the support mechanism 6 can also be a hydraulic cylinder or pneumatic cylinder support mechanism as in the prior art, and this embodiment is not limited thereto.

[0063] This embodiment also provides a vessel, including a hull 100 and a hatch cover provided in this embodiment. The hull 100 has a storage compartment with a hatch 101. The hatch cover body 1 is rotatably connected to the hull 100, capable of closing or opening the hatch 101. When the hatch cover's boom 21 can meet the lifting requirements, a crane can be directly eliminated, reducing the vessel's cost. Furthermore, the boom 21 is simple to install, applicable to hatch covers of various vessels, has a wide range of applications, and offers high flexibility in use.

[0064] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
