[0020] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0021] Embodiment 1: A new type of foldable hatch coaming platform for timber carriers, such as Figure 1 As shown, it includes a hatch coaming 1, which is arranged on the deck. The hatch coaming 1 includes a vertical coaming 2 and a horizontal coaming 3. The horizontal coaming 3 is connected to the outer side of the upper edge of the horizontal coaming 3 to form an installation space 4 below the horizontal coaming 3. A plurality of webs 5 parallel to the horizontal coaming 3 are welded on the vertical coaming 2. In actual production, a plurality of webs 5 are provided. Only one web is shown in this embodiment. In actual use, a track or the like is provided on the horizontal coaming 3 to cooperate with the hatch cover to play the functions of opening, closing, sealing, etc., which is inconvenient for operators to stand, and the probability of falling into the large cabin when standing on the horizontal coaming 3 is higher, which is dangerous; the foldable hatch coaming 1 platform is arranged in the installation space 4, including a flip platform plate 6, which rotates around a flip axis 15 to form a storage state and a use state. In the storage state, the flip platform plate 6 is turned into the installation space 4, and the flip platform plate 6 is divided by the flip axis 15 on one side as a footrest area 36 7 and the other side as a fixed area 8; as shown Figure 1 , 2 As shown, when it is needed, the flip platform board 6 is turned out to a horizontal state, so that its footrest 36 area 7 is horizontally extended to the outside of the horizontal coaming 3 when in use, forming an operating space for personnel to stand; so that the crew can stand on the platform to observe the situation in the large cabin, and it is also convenient to operate the hatch cover and other related equipment, which is safer. And as a timber transport ship, its deck is also used as a place for stacking logs. In order not to affect the stacking of logs and the platform cannot be crushed by logs, so when not in use, the flip platform board 6 is transformed into Figure 2 The storage state shown in the figure can free up the loading space on the deck without affecting the stacking of logs.

[0022] It also includes a support structure 9, which serves as the installation base of the flip platform plate 6, for its rotation and positioning and providing a certain height; Figure 1 , 2 As shown, the support structure 9 includes columns 14 respectively arranged on both sides of the flip platform plate 6. In this embodiment, the columns 14 are made of L-shaped steel, and other profiles can also be used without limitation. In short, it is sufficient to provide an installation foundation for a flip axis 15 for the flip platform plate 6, so that the flip platform plate 6 can be rotated and changed. The bottom of the column 14 is fixedly connected to the deck, and the upper ends of the two columns 14 are connected to form a flip axis 15 for the flip platform plate 6 to rotate; Figure 1 , 2 As shown, in this embodiment, screw holes are provided on the column 14 and the flip platform plate 6 at corresponding positions of the flip axis 15. During installation, the flip platform can be conveniently installed by inserting bolts into the corresponding screw holes of the two components, and it is also convenient to disassemble. The flip axis 15 can also adopt other forms, such as using an axial rod to pass through the screw holes of the two components. Preferably, two bolts are used on both sides of the flip platform plate 6 as the flip axis 15, which is convenient for installation and disassembly, and its flip function is normal.

[0023] It also includes a positioning structure for maintaining the state of the flip platform plate 6 when it is in the storage state or the use state, including a first positioning base point 10, a second positioning base point 11, and a third positioning base point 12. The first positioning base point 10 is set at one end of the flip platform plate 6 located in the installation space 4, the second positioning base point 11 is set on the web 5, and the third positioning base point 12 is set on the horizontal enclosure 3. The first positioning base point 10 rotates around the flip axis 15 as the axis to form an arc trajectory, so that the second positioning base point 11 and the third positioning base point 12 are located on the arc trajectory; the first positioning base point 10 is respectively connected with the second positioning base point 11 and the third positioning base point 12 to form the storage state or the use state.

[0024] Specifically, the fixing area 8 is a fixing arm 16 extending from both sides of the flip platform plate 6 in the length direction. Figure 1-3As shown, when the flip platform plate 6 is switched between the storage state and the use state, the fixed arm 16 moves with its end portion along an arc trajectory in the installation space 4. In this embodiment, the second positioning base point 11 includes an avoidance vertical plate 17 extending outward to avoid interference with the web 5. The end of the avoidance vertical plate 17 is connected to a horizontal positioning vertical plate 18 for positioning the flip platform plate 6 in a horizontal position. When setting the second positioning base point 11, a web 5 with a more suitable position can be selected as its installation basis, and the avoidance vertical plate 17 is welded and fixed to the web 5 so that its end portion extends outward, thereby preventing the fixed arm 16 from interfering with the web 5. In addition, in order to locate the horizontal position of the flip platform plate 6, a horizontal positioning plate in the vertical direction is provided at the end of the avoidance vertical plate 17, as shown in FIG. Figure 1 As shown, according to the horizontal position of the flip platform plate 6, a second positioning hole 21 is drilled on the horizontal positioning plate, and the end of the fixed arm 16 is provided with a first positioning hole 20. When the flip platform plate 6 is in a horizontal position, the first positioning hole 20 coincides with the second positioning hole 21. Bolts are inserted into the two holes and tightened to position the flip platform plate 6 in a horizontal position. Furthermore, in order to position the flip platform plate 6 in the storage state, a third positioning base point 12 is provided, which includes a vertical positioning stand 19 installed on the horizontal enclosure 3. Figure 1 As shown, the vertical positioning plate 19 is welded to the lower end surface of the horizontal enclosure 3, and a third positioning hole 22 is provided on the vertical positioning plate 19. Figure 3 As shown, when the device is turned to the storage state, the first positioning hole 20 and the third positioning hole 22 overlap each other, and bolts are inserted into the two holes and tightened to position the flip platform plate 6 in a vertical position.

[0025] It also includes a fence structure 13, which is detachably connected to the flip platform plate 6. Figure 1 As shown, the fence frame 23 is installed on the flip platform. Specifically, the fence structure 13 includes a fence frame 23 arranged in an L-shaped corner on two adjacent sides of the footrest 36 area 7 except the horizontal enclosure 3, and the other side is for personnel entrance and exit. A fence chain (not shown in the figure) with a blocking function and easy to open is pulled on the entrance and exit; a plug rod 24 is provided at the bottom of the fence frame 23, and a positioning sleeve 25 corresponding to the plug rod 24 is provided on the footrest 36 area 7.

[0026] In this embodiment, the fence structure 13 is a fixed structure, and its bottom is installed and fixed by inserting the plug rod 24 into the positioning sleeve 25 set at the corresponding position around the pedal 36 area 7. Figure 1The fence structure 13 is inserted into the positioning sleeve 25 when in use. It is understood that the positioning sleeve 25 should fix the plug rod 24 to prevent the fence frame 23 from falling off during use. Specifically, the positioning sleeve 25 and the insertion foot can be fixed by bolts through holes; or elastic keys and pin holes can be used to achieve convenient installation and removal. The fixing method is not limited. When the platform is finished using, first remove the fence structure 13 from the footrest 36 area 7, and then turn the flip platform board 6 to the vertical storage state, such as Figure 2 shown.

[0027] Embodiment 2: Improvements are made on the basis of the above-mentioned embodiment. In the above-mentioned embodiment, the fence structure 13 is a fixed form, and it is an L-shaped corner structure. When it is stored, it is separated from the platform and needs to be stored separately, which takes up space and is repeatedly carried and moved, which is easy to cause loss or damage. As a result, the crew does not install the fence when using it, which increases the danger. In order to facilitate the erection of the fence structure 13 and to facilitate storage, it will not be lost or abandoned due to separation and storage. In this embodiment, the fence structure 13 is combined with the flip platform plate 6 to store or unfold them together.

[0028] Specifically, the fence structure 13 is a foldable and retractable connection, such as Figure 3-5 As shown, it includes a first hinged fence 26 and a second hinged fence 27. The bottom of the first hinged fence 26 is hinged to the side of the footrest 36 area 7 away from the horizontal enclosure 3, so that the first hinged fence 26 overlaps within the range of the flip platform board 6 when stored, as shown in FIG. Figure 3 As shown, the fence structure 13 is first overlapped and then folded and fitted onto the flip platform board 6. Specifically, the bottom of the first articulated fence frame 26 is hinged to the footrest 36 area 7, and the footrest 36 area 7 is provided with an articulated seat. Taking the figure as an example, two articulated seats are provided, and then two corresponding articulated ears are provided at the bottom of the first articulated fence frame 26, so that the first articulated fence frame 26 can be rotated to form a state of being fitted onto the flip platform board 6 or vertically on the flip platform board 6; further, a second articulated fence frame 27 is hingedly provided on one side of the first articulated fence frame 26, so that one side of the L-shaped fence structure 13 can be rotated to fit on the other side to form a flat structure that is easy to store, and then the two are fitted onto the flip platform board 6 as a whole. When the first articulated fence frame 26 and the second articulated fence frame 27 are unfolded, Figure 4 , 5 As shown, the second articulated fence 27 is unfolded on the side of the first articulated fence 26 to form a fence on the adjacent two sides of the footrest area 36 7, so as to achieve the purpose of protecting the safety of the standing area of ​​​​people; when the second articulated fence 27 is stored, it overlaps with the first articulated fence 27 for easy storage, such as Fig. 9As shown. The bottom end of the second articulated fence frame 27 away from the first articulated fence frame 26 is provided with a fixed foot 28, and the footrest 36 area 7 is provided with a slot 29 matched with the fixed foot 28; since the bottom of the first articulated fence frame 26 is hinged, in order to fix the fence structure 13, in this embodiment, the second articulated fence frame 27 is fixed to the footrest 36 area 7, and when the footrest 36 area 7 of the second articulated fence frame 27 is rotated and opened, the fixed foot 28 at the bottom end of the second articulated fence frame 27 is just inserted into the slot 29, and the two can be fixed by inserting bolts, so that the entire fence frame body 23 can be fixed. This structure is easy to use, fast to unfold or store, simple in structure, and effectively avoids the disadvantage of inconvenient storage of the fence frame body 23.

[0029] Embodiment three: The pillar 14 is hinged with a side support plate 32, which is rotated outward and supported on the lower end surface of the footrest 36 when in use. Figure 5 , 6 As shown, in order to improve the bearing capacity of the footrest 36 area 7 and improve the stability of the footrest 36 area 7, a side support plate 32 that is flipped outward is provided, which is supported on the lower end surface of the footrest 36 area 7 to maintain the flip platform plate 6 on a horizontal plane, thereby effectively improving the stability and bearing capacity. In this embodiment, a side support plate 32 is hingedly provided on one side column 14, and can also be provided on both sides. Since the side support plate 32 is hinged, it can be formed when stored as shown. Fig. 9 The superimposed structure shown.

[0030] In order to prevent the side support plate 32 from excessively rotating and losing support for the footrest 36 area 7 after opening, a limiting groove structure for the side support plate 32 is set on the bottom surface of the footrest 36 area 7, and a protrusion 33 is provided at the upper end of the side support plate 32, which supports the footrest 36 area 7 through the protrusion 33. The limiting groove structure is set on the arc trajectory of the rotation of the protrusion 33. The limiting groove structure includes a baffle 34 and a slope 35. During the process of the side support plate 32 rotating and opening, the protrusion 33 first passes through the slope 35, and enters the limiting groove structure along with the moving guide. The baffle 34 and the slope 35 limit the two sides of the protrusion 33 to prevent the side support plate 32 from rotating.

[0031] Preferably, the side support plate 32 is arranged on the side of the personnel entrance and exit, and a footrest 36 for personnel to climb is formed on the side support plate 32; Figure 5 , 6 As shown, the footrest 36 is a through hole set on the side support plate 32. People can step on the hole to climb up, so that the side support plate 32 not only has the function of supporting the flip platform plate 6, but also has the function of a ladder for people to go up and down, making it convenient for crew members to go up and down the hatch enclosure 1 platform.

[0032] Embodiment 4: The support structure 9 also includes an inner diagonal brace 30 disposed inside the column 14, an X-shaped diagonal brace 31 is connected between the two columns 14, and the planes where the inner diagonal brace 30 and the X-shaped diagonal brace 31 are located are perpendicular to each other. In the aforementioned embodiment, support is achieved only by two vertical columns 14, and its lateral stability is poor. In this embodiment, the lateral stability of the hatch coaming 1 platform is effectively improved by adding the X-shaped diagonal brace 31 and the inner diagonal brace 30.

[0033] It is worth noting that when this embodiment is combined with the third embodiment, the second positioning base point 11 and the third positioning base point 12 do not need to be set, so that the hot welding on the hatch coaming 1 can be reduced. Since the hatch coaming 1 is a strong structure on the cargo hold deck to reduce the torsional stress of the hull, the welding and flame cutting of its plate are reduced, and its strength can be effectively maintained. On the basis of the combination of the third and fourth embodiments, the second positioning base point 11 and the third positioning base point 12 can be cut off.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
