In addition, some aspects disclosed in the present invention can be used alone or in any appropriate combination with other aspects disclosed in the present invention.
[0024] Example 1
[0025] like Figure 1-5The first embodiment of the present invention is shown in FIG. 1 , which provides a hatch cover for a side-thrust bulk carrier, including a hatch cover assembly 1. The hatch cover assembly 1 includes a hatch 101 and a cover plate 102. There are two cover plates 102, which are respectively installed on both sides of the top of the hatch 101. An opening and closing mechanism 2 is installed on the surface of the hatch 101. The opening and closing mechanism 2 is provided with four groups and is respectively located around the hatch cover assembly 1. The opening and closing mechanism 2 includes a through slot 201, a gear 202, a servo motor 203, a reducer 204, a transmission rod 205, a rack 206, a connecting rod 207, and a concave plate 208. , guide roller 209, guide rail 210, concave plate 208, guide roller 209 and guide rail 210 are used to limit the movement trajectory of the cover 102, the through slot 201, gear 202, servo motor 203, reducer 204, transmission rod 205 and rack 206 are used to open and close the cover 102, the rack 206, connecting rod 207, concave plate 208 and guide roller 209 are all installed at the bottom of the cover 102, and the through slot 201, gear 202, servo motor 203, reducer 204, transmission rod 205 and guide rail 210 are all installed on the surface of the hatch 101.
[0026] like Figure 1-5 As shown, the hatch 101 and the cover plate 102 cooperate to seal the cargo hold, and the gap formed by the separation of the two cover plates 102 can facilitate the addition of bulk materials into the cargo hold. The output shaft of the servo motor 203 rotates through the reducer 204 to drive the transmission rod 205 to rotate. When the transmission rod 205 rotates, it drives the gear 202 to rotate. When the gear 202 rotates, it drives the rack 206 to move. When the rack 206 moves, it drives the cover plate 102 to move through the connecting rod 207. While the cover plate 102 moves, it drives the guide roller 209 to move along the surface of the guide rail 210 through the concave plate 208, so that the cover plate 102 can seal or release the cargo hold. There are four opening and closing mechanisms 2, and each two opening and closing mechanisms 2 form a group to drive one cover plate 102 to move. The independent drive of the opening and closing mechanism 2 allows the cover plate 102 to be opened and closed individually, which effectively improves the flexibility of the use of the cover plate 102.
[0027] Example 2
[0028] Reference Figure 1 、 2 , 3 and 5 are the second embodiment of the present utility model, which is based on the previous embodiment.
[0029] In this embodiment, the through groove 201 is opened around the top of the hatch 101, the gear 202 is installed in the inner cavity of the through groove 201, and is movably connected to the inner wall of the through groove 201 through a bearing, the servo motor 203 and the reducer 204 are both fixed to the surface of the hatch 101, one end of the transmission rod 205 is transmission-connected to the output shaft of the reducer 204, and the other end of the transmission rod 205 is transmission-connected to the gear 202.
[0030] One end of the connecting rod 207 is fixedly connected to the cover plate 102 , and the other end of the connecting rod 207 is fixedly connected to the rack 206 . The gear 202 is meshed with the rack 206 .
[0031] The guide rail 210 is fixed to the top of the hatch 101, the concave plate 208 is fixed to the bottom of the cover plate 102, and the guide roller 209 is installed in the inner cavity of the concave plate 208 through a bearing. The surface of the concave plate 208 is engaged with the guide rail 210 and is slidably connected to the surface of the guide rail 210.
[0032] like Figure 1 、 2 As shown in Figures 3 and 5, the cover plate 102 moves while the guide roller 209 is driven by the concave plate 208 to move along the surface of the guide rail 210. The concave plate 208, the guide roller 209 and the guide rail 210 cooperate to limit the movement trajectory of the cover plate 102 to prevent the cover plate 102 from deflecting during the movement. The output shafts of the two opening and closing mechanisms 2 on the left and the two opening and closing mechanisms 2 on the right move in opposite directions, thereby ensuring that the two cover plates 102 gradually move away from or closer to each other.
[0033] Example 3
[0034] Reference Figure 1 、 2 and 4, which are the third embodiment of the present invention, and this embodiment is based on the first two embodiments.
[0035] In this embodiment, the hatch cover assembly 1 also includes a support rod 103, a support roller 104, an airbag 105, a positioning groove 106 and a positioning plate 107. The support rod 103 and the support roller 104 are used to provide support for the cover 102, and the airbag 105, the positioning groove 106 and the positioning plate 107 are used to seal the hatch 101 and the cover 102.
[0036] One end of the support rod 103 is fixedly connected to the cover plate 102 , and the other end of the support rod 103 is movably connected to the support roller 104 via a bearing. The airbag 105 is installed at the edge of the hatch 101 surface.
[0037] The positioning groove 106 is formed on the surface of one side cover plate 102 , and the positioning plate 107 is fixed on the surface of the other side cover plate 102 . One end of the positioning plate 107 extends to the inner cavity of the positioning groove 106 and is movably connected to the inner cavity of the positioning groove 106 .
[0038] like Figure 1 、 2As shown in Figure 4, the cover 102 moves while the support roller 104 is driven to move by the support rod 103. The support rod 103 and the support roller 104 can provide support for the cover 102. After the two cover plates 102 are attached, the positioning plate 107 extends to the inner cavity of the positioning groove 106, so that the connection between the two cover plates 102 can be sealed. After the cover plates 102 are closed, the airbag 105 is inflated by compressed air, so that the airbag 105 can fill the connection between the hatch 101 and the cover plate 102, thereby achieving a sealing effect.
[0039] When in use, the output shaft of the servo motor 203 rotates through the reducer 204 to drive the transmission rod 205 to rotate. When the transmission rod 205 rotates, it drives the gear 202 to rotate. When the gear 202 rotates, it drives the rack 206 to move. When the rack 206 moves, it drives the cover 102 to move through the connecting rod 207. When the cover 102 moves, it drives the guide roller 209 to move along the surface of the guide rail 210 through the concave plate 208, so that the cover 102 can cover or release the cargo hold. While 102 is moving, the support roller 104 is also driven to move through the support rod 103. The support rod 103 and the support roller 104 can provide support for the cover plate 102. After the two cover plates 102 are fitted together, the positioning plate 107 extends to the inner cavity of the positioning groove 106, so that the connection between the two cover plates 102 can be sealed. After the cover plates 102 are closed, the airbag 105 is inflated by compressed air, so that the airbag 105 can fill the connection between the hatch 101 and the cover plate 102, thereby achieving a sealing effect.
