[0002] Ships are an important means of water transportation. In the field of modern cargo holds, especially the cargo holds of medium and large multi-purpose ships and ultra-large ore carriers, side-sliding hatch covers are usually equipped.

[0003] In order to facilitate the loading and unloading of cargoes on ships, a side-sliding hatch cover usually includes a cover plate and a driving device. The driving device can lift the cover plate. Rollers are arranged on the cover plate, and the hatch enclosure is provided with a limit device for limiting the movement of the rollers and a guide rail for guiding the movement of the rollers.

[0004] When the cover plate is wide, due to its heavy weight, the driving device can only lift the cover plate near it, and the hatch cover far away from the driving device will be deformed under its own gravity. It is difficult to lift the entire cover plate evenly relying on the driving device alone, which affects the overall lifting effect of the cover plate. In order to allow the roller to disengage from the limit device, it is necessary to add additional lifting devices on both sides of the cover plate. First, the cover plate is lifted vertically to allow the cover plate to move horizontally along the guide rail direction, and then the cover plate is moved horizontally. However, the opening and closing process of the cover plate with a large width is complicated, the opening and closing efficiency is low, and the opening and closing difficulty is great.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] See also Figures 1 to 4 The present invention provides a side-sliding hatch cover, which is arranged on a hatch body 4. The side-sliding hatch cover includes a cover plate 1, a lifting device 2 and a translation device 3. The cover plate 1 is provided with a roller 11, and the hatch body 4 is provided with a guide rail 41. The roller 11 and the guide rail 41 can be selectively connected; the lifting device 2 includes a lifting ear plate 21 and a lifting drive assembly 22. The lifting drive assembly 22 includes a lifting drive member 221. The lifting drive member 221 is connected to the lifting ear plate 21 in a transmission manner so that the lifting ear plate 21 rotates. 1 has a covering position and a lifting position. When the lifting ear plate 21 rotates from the covering position to the lifting position, the cover plate 1 generates displacements in the horizontal and vertical directions, and the roller 11 is located in the guide rail 41; the translation device 3 includes a translation driving arm 31 and a translation driving assembly 32. The translation driving arm 31 is arranged on the cover plate 1 and moves synchronously with the cover plate 1. The translation driving assembly 32 includes a translation driving member 321. The translation driving member 321 is transmission-connected with the translation driving arm 31 to enable the translation driving arm 31 to move in the horizontal direction.

[0036] In this embodiment, the cover plate 1 is provided with one, the lifting device 2 and the translation device 3 are both arranged on the side of the cover plate 1 facing the outside world (that is, the side of the opening direction of the cover plate 1), two groups of rollers 11 are provided, and the two groups of rollers 11 are respectively arranged on the two side walls of the cover plate 1 perpendicular to the translation direction, one group of rollers 11 includes two rollers 11, the guide rails 41 and the rollers 11 are arranged one by one, the hatch body 4 is provided with limiting grooves 42 arranged one by one with the rollers 11, the limiting grooves 42 are correspondingly arranged on the side of the guide rails 41 away from the outside world, for limiting the movement of the rollers 11, the translation driving arm 31 is arranged on the side wall of the cover plate 1 facing the outside world, and the end of the translation driving arm 31 away from the cover plate 1 protrudes from the cover plate 1.

[0037] It should be noted that when the lifting ear plate 21 is in the covering position, the cover 1 is covered on the hatch body 4, and the roller 11 is located in the limiting groove 42, so that the movement of the cover 1 is restricted, and the lifting drive member 221 drives the lifting ear plate 21 to rotate from the covering position to the lifting position, and the cover 1 is subjected to the force in the horizontal direction and the lifting force in the vertical direction, so that the cover 1 is lifted and moved toward the outside, that is, the cover 1 moves in the oblique upward direction, so that the roller 11 is disengaged from the limiting groove 42 and enters the guide rail 41, and the limitation of the roller 11 and the cover 1 is released, and the translation drive member 321 drives the translation drive arm 31 and the cover 1 to translate toward the outside, so as to realize the opening of the cover 1, so that the cabin is connected with the outside, which is convenient for loading cargo; when the cover 1 needs to be covered, the cover 1 is translated in the opposite direction, and the lifting ear plate 21 is rotated in the opposite direction to the covering position.

[0038] In this way, the lifting drive member 221 lifts the cover plate 1 and moves toward the outside at the same time, generating displacements in the vertical and horizontal directions, and enabling the roller 11 to disengage from the limiting groove 42 and directly enter the guide rail 41, so that the translation drive member 321 can drive the cover plate 1 to translate, thereby simplifying the opening and closing process of the cover plate 1, and making the lifting process and the opening and closing process proceed continuously, thereby improving the opening and closing efficiency and reducing the opening and closing difficulty; the lifting device 2 and the translation device 3 are both arranged on the side of the cover plate 1 facing the outside, which can reduce the interference between the cover plate 1 and the lifting device 2 and the translation device 3 during the movement of the cover plate 1, and the lifting device 2 and the translation device 3 have a simple structure, which is convenient for the staff to assemble and maintain.

[0039] It is understandable that two cover plates 1 can also be provided, and both cover plates 1 are provided with a lifting device 2 and a translation device 3, and the moving directions of the two cover plates 1 are opposite. The number and setting positions of the cover plates 1 can be adjusted according to the actual design of the cabin, and no further examples are given here.

[0040] Furthermore, the hatch body 4 may be provided with a sensor for detecting the lifting status of the cover 1, and the sensor and the translation drive component 321 may be communicated through the control module, so that after the sensor receives the signal that the cover 1 is lifted into place, it controls the translation drive component 321 to work, so as to drive the translation drive arm 31 and the cover 1 to translate, and the roller 11 to roll in the guide rail 41.

[0041] See also Figure 1 In some embodiments, two lifting devices 2 are provided, and the translation device 3 is provided between the two lifting devices 2 .

[0042] In this embodiment, the two lifting devices 2 are respectively arranged at the two ends of the side wall of the cover plate 1 facing the outside, that is, the two lifting devices 2 are respectively arranged close to the two groups of rollers 11, and the two lifting devices 2 are symmetrically arranged along the axis of the translation direction of the cover plate 1, the axis of the translation driving arm 31 coincides with the axis of the translation direction of the cover plate 1, and the translation device 3 is arranged at a position corresponding to the translation driving arm 31.

[0043] In this way, the two groups of lifting devices 2 can lift the cover plate 1 respectively, so that the rollers 11 on both sides disengage from the limiting grooves 42 and enter the guide rails 41, thereby improving the stability of the cover plate 1 during the lifting process. The translation device 3 arranged in the middle position of the cover plate 1 makes the cover plate 1 more evenly stressed during translation, reduces the deformation of the cover plate 1, and enables the cover plate 1 to be lifted and translated smoothly, thereby reducing the difficulty of opening and closing and improving the opening and closing efficiency.

[0044] It is understandable that the jacking device 2 can also be provided with four groups or six groups, and the translation device 3 can also be provided with multiple groups accordingly. The setting positions of the jacking device 2 and the translation device 3 can be adjusted according to actual needs, and can achieve stable lifting and translation of the cover plate, which will not be elaborated here.

[0045] Furthermore, the side-sliding hatch cover also includes a frequency conversion system (not shown in the figure), which is connected to the jacking drive components 221 of the two sets of jacking devices 2, so that the two jacking drive components 221 can synchronously drive the jacking ear plates 21 to rotate, thereby realizing synchronous jacking of both sides of the cover plate 1.

[0046] It should be noted that controlling the synchronous driving of the lifting drive member 221 by a frequency conversion system is a prior art and will not be described in detail here.

[0047] See also Figure 6 to Figure 7 In some embodiments, the cover plate 1 is connected with a pin shaft 12, and the pin shaft 12 is arranged in a one-to-one correspondence with the lifting ear plate 21. The lifting ear plate 21 includes a connecting portion 211, and the connecting portion 211 is a hook-shaped structure. The connecting portion 211 and the lifting ear plate 21 can be selectively clamped.

[0048] In this embodiment, a transition plate 13 is connected to the side of the cover plate 1 facing the outside, a pin shaft 12 is fixedly arranged at the end of the transition plate 13 facing the outside, the pin shaft 12 is located below the cover plate 1, and a connecting portion 211 is arranged on the side of the lifting ear plate 21 facing the cover plate 1, and when the lifting ear plate 21 is in the lifting position, the opening of the connecting portion 211 is arranged to face the outside.

[0049] In this way, when the lifting ear plate 21 is in the covering position, the opening of the connecting portion 211 faces upward, and the pin shaft 12 is located above the connecting portion 211 and is engaged with the connecting portion 211. During the process of the lifting ear plate 21 rotating to the lifting position, the connecting portion 211 hooks the pin shaft 12 and lifts the pin shaft 12, so that the pin shaft 12 drives the transition plate 13 and the cover plate 1 to produce horizontal and vertical displacements. Since the cover plate 1 moves toward the outside, it can drive the roller 11 to produce horizontal displacement, disengage from the limiting groove 42 and enter the guide rail 41. When the lifting ear plate 21 is in the lifting position, the opening of the connecting portion 211 faces the outside, so that the cover plate 1 can move outward, thereby realizing the opening action of the side-sliding hatch cover.

[0050] It can be understood that the pin shaft 12 can also be directly set on the cover plate 1. In this embodiment, the pin shaft 12 is set on the transition plate 13 to facilitate the horizontal and vertical displacement of the cover plate 1 under the action of the lifting ear plate 21 and reduce the movement interference with the cover plate 1. The setting position of the pin shaft 12 can be flexibly adjusted according to actual needs.

[0051] See also Figure 7 In some embodiments, the lifting drive assembly 22 also includes a driving base 222, a driving connecting rod 223 and a lifting lever 224. The lifting drive member 221 is connected to the driving base 222 in a transmission manner so that the driving base 222 slides in a horizontal direction. The two ends of the driving connecting rod 223 are respectively hinged to the driving base 222 and the lifting lever 224. The end of the lifting lever 224 that is away from the driving connecting rod 223 rotates synchronously with the lifting ear plate 21.

[0052] In this embodiment, the driving base 222 is slidably arranged on the hatch body 4 along the horizontal direction, and the first hinge 2231 and the second hinge 2232 are respectively arranged at both ends of the driving connecting rod 223. The driving connecting rod 223 and the driving base 222 are hinged through the first hinge 2231, and the driving connecting rod 223 and the lifting lever 224 are hinged through the second hinge 2232. The driving connecting rod 223 and the lifting lever 224 are arranged on the same side of the driving base 222, and the length of the driving connecting rod 223 is greater than the length of the lifting lever 224.

[0053] It should be noted that when the cover plate 1 needs to be lifted, the driving base 222 slides in the direction close to the cover plate 1 under the action of the lifting driving member 221, so that the lifting ear plate 21 is driven by the driving connecting rod 223 and the lifting lever 224 to rotate from the covering position to the lifting position. After the lifting ear plate 21 rotates to the lifting position, the cover plate 1 can move freely in the direction toward the outside, and the translation driving member 321 drives the translation driving arm 31 and the cover plate 1 to move outward, so as to realize the side-shift cabin. Opening of the opening cover; when the hatch body 4 needs to be closed, the translation drive member 321 reversely drives the translation drive arm 31 and the cover plate 1 to move inward (that is, in the direction close to the hatch body 4), and after the pin shaft 12 abuts against the connecting part 211, the jacking drive member 221 drives the jacking ear plate 21 to rotate from the jacking position to the closing position. As the cover plate 1 gradually moves inward and closes the hatch body 4, the roller 11 moves along the guide rail 41 and enters the limit groove 42, thereby limiting the cover plate 1.

[0054] In this way, the driving base 222 slides in the horizontal direction and drives the driving connecting rod 223 and the lifting lever 224 to move, so that the lifting driving component 221 can be set outside the hatch body 4, and the overall structure of the lifting device 2 is simplified, which is convenient for the staff to operate and maintain, and the lifting action of the cover 1 is more stable and controllable, which makes it easier to disengage the roller 11 from the limiting groove 42, thereby reducing the influence of the cover 1's own weight on the lifting process, improving the opening and closing efficiency, and reducing the difficulty of opening and closing.

[0055] It can be understood that the jacking drive member 221 can also directly drive the jacking ear plate 21 to rotate. In this embodiment, the driving connecting rod 223 and the jacking lever 224 are provided to reduce the interference between the jacking drive member 221 and the cover plate 1 and make the rotation of the jacking ear plate 21 more stable. The connection method between the jacking drive member 221 and the jacking ear plate 21 can be flexibly adjusted according to actual needs, which will not be elaborated here.

[0056] See also Figure 7 and Figure 8 In some embodiments, the lifting drive assembly 22 also includes a lifting gear 225 and a lifting rack 226, the lifting drive member 221 is connected to the lifting gear 225 in a transmission connection, the lifting gear 225 is arranged on the driving base 222, and the lifting rack 226 is connected to the lifting gear 225 in a transmission connection so that the driving base 222 slides in a horizontal direction.

[0057] Among them, the jacking gear 225 and the jacking rack 226 are both arranged above the driving base 222, the relative position of the jacking rack 226 and the hatch body 4 is fixed, the jacking gear 225 is arranged on the side of the jacking rack 226 away from the driving connecting rod 223, the jacking driving member 221 is a motor, and the jacking driving member 221 is arranged below the driving base 222, and the output end of the jacking driving member 221 is fixedly connected to the jacking gear 225 to drive the jacking gear 225 to rotate.

[0058] In this way, the lifting drive member 221 transmits the driving force to the lifting gear 225 and the lifting rack 226, and drives the driving base 222 to move in the horizontal direction, thereby driving the driving connecting rod 223 and the lifting lever 224 to move, so that the lifting ear plate 21 rotates, and the lifting ear plate 21 is switched between the covering position and the lifting position, which simplifies the opening and closing process of the cover 1 and improves the opening and closing efficiency. The two lifting ear plates 21 are respectively connected to the corresponding pin shafts 12, which can stably lift the two sides of the cover 1, so that the roller 11 moves out of the limit groove 42 and enters the guide rail 41, reducing the difficulty of opening and closing.

[0059] It can be understood that the jacking drive member 221 can also be arranged above the driving base 222. The jacking drive member 221 can also be a linear drive mechanism such as a cylinder or a linear motor directly connected to the driving base 222. The setting position and specific type of the jacking drive member 221 can be flexibly adjusted according to actual needs, so as to enable the driving base 222 to move in the horizontal direction and drive the jacking ear plate 21 to rotate. No more examples are given here. In this embodiment, the jacking drive member 221 is arranged below the driving base 222 to reduce the interference between the cover plate 1 and the jacking drive member 221 during the movement, so as to improve the stability and safety of the opening and closing process.

[0060] See also Figure 7 and Figure 8 In some embodiments, the lifting device 2 further includes a lifting base 23 and a guide slide bar 24 , the guide slide bar 24 is fixedly disposed on the lifting base 23 , and the driving base 222 is slidably disposed on the guide slide bar 24 .

[0061] In this embodiment, the jacking base 23 is fixedly arranged on the deck (not shown in the figure), and the jacking rack 226 is fixedly arranged on the jacking base 23. The length direction of the jacking base 23, the length direction of the jacking rack 226, and the length direction of the guide slide bar 24 are all parallel, so that the driving base 222 can slide along the length direction of the guide slide bar 24. A third hinge 2241 is arranged on the end of the jacking lever 224 away from the driving connecting rod 223, and the jacking lever 224 is hinged to the jacking base 23 through the third hinge 2241.

[0062] In this way, the lifting base 23 can stably support the driving base 222, so that the driving base 222 can move smoothly along the length direction of the guide slide rod 24, and drive the lifting ear plate 21 to switch between the covering position and the lifting position, thereby simplifying the opening and closing process of the cover 1 and improving the stability of the cover 1 during movement.

[0063] Furthermore, the lifting lugs 21 of the two lifting devices 2 are respectively arranged on the side of the two driving bases 222 away from each other, that is, the driving connecting rods 223 and lifting levers 224 of the two lifting devices 2 are respectively arranged on the side of the two moving bases 222 away from each other.

[0064] It can be understood that the lifting ear plates 21 of the two sets of lifting devices 2 can also be set on the side where the two driving bases 222 are close to each other. In this embodiment, they are set on the side away from each other in order to make the lifting ear plates 21 closer to the roller 11, so as to facilitate the roller 11 to disengage from the limiting groove 42 and enter the guide rail 41 during the lifting process.

[0065] See also Figure 4 and Fig. 9In some embodiments, the translation drive assembly 32 also includes a translation base 322, a translation gear 323 and a first rack 324. The translation drive member 321 and the translation gear 323 are both arranged on the translation base 322. The translation drive member 321 is transmission-connected to the translation gear 323. The translation gear 323 is transmission-connected to the first rack 324. The first rack 324 is arranged on the translation drive arm 31.

[0066] In this embodiment, the translation base 322 is fixedly arranged on the hatch body 4, and the translation base 322 includes a vertical support portion 3221 and a horizontal driving portion 3222. The vertical support portion 3221 is fixedly arranged on the deck, and the translation driving member 321 is a motor. The translation driving member 321 is arranged below the driving portion 3222 of the translation base 322. The output end of the translation driving member 321 passes through the driving portion 3222 and is fixedly connected to the translation gear 323. Two sets of synchronous gears 3231 are respectively connected on both sides of the translation gear 323 (see Figure 5 ) so that the driving force of the translation drive member 321 is transmitted to the two sets of synchronous gears 3231 through the translation gear 323, and the two sets of synchronous gears 3231 rotate synchronously, one set of synchronous gears 3231 includes two gears arranged vertically coaxially, and the length of the first rack 324 is greater than the interval between the two sets of synchronous gears 3231.

[0067] In this way, when the lifting ear plate 21 rotates to the lifting position, the roller 11 is lifted to enter the guide rail 41. Due to the horizontal and vertical displacements of the cover 1, the first rack 324 arranged on the translation drive arm 31 engages with the synchronous gear 3231 arranged near the cover 1, and the translation drive member 321 drives the synchronous gear 3231 to rotate, so that the first rack 324 moves in the horizontal direction and engages with another set of synchronous gears 3231, thereby realizing the opening action of the cover 1, so that the cover 1 can be linked to perform a translation action after being lifted, thereby simplifying the opening and closing process of the cover 1, improving the opening and closing efficiency, and reducing the difficulty of opening and closing.

[0068] It can be understood that the top surface of the translation base 322 may also be provided with a guiding groove, and the translation driving arm 31 may be provided with a slider corresponding to the groove, so that the translation driving arm 31 can drive the cover 1 to move along a fixed direction, which will not be listed in detail here; the translation driving member 321 may also be a linear driving mechanism directly connected to the translation driving arm 31, such as a linear motor, a cylinder, etc., which is not limited to the present embodiment.

[0069] See also Figure 4In some embodiments, the translation drive assembly 32 further includes a second rack 325, the second rack 325 is coaxially arranged with the first rack 324, the second rack 325 is transmission-connected with the translation gear 323, and the second rack 325 is spaced apart from the first rack 324. Further, in some embodiments, the length of the second rack 325 is greater than the length of the first rack 324.

[0070] Among them, the length direction of the second rack 325 is parallel to the translation direction of the cover 1, and the interval between the second rack 325 and the first rack 324 is smaller than the interval between the two sets of synchronous gears 3231, so that when the cover 1 is translated outward, when the first rack 324 is disengaged from the synchronous gear 3231 set close to the outside, the second rack 325 can engage with the synchronous gear 3231 set close to the cover 1, thereby realizing the continuity of the translation of the cover 1, and the lower edge of the second rack 325 is lower than the outer edge of the hatch body 4.

[0071] In this way, the second rack 325 with a longer length can extend the moving distance of the cover 1 and improve the opening and closing effect, so that after the cover 1 is lifted, the first rack 324 engages with the synchronous gear 3231, and the cover 1 enters a translation state. At the same time, the second rack 325 moves synchronously to a position at the same height as the synchronous gear 3231, so that the second rack 325 can smoothly pass through the hatch body 4 and engage with the synchronous gear 3231, thereby simplifying the opening and closing process, improving the opening and closing efficiency, and reducing the difficulty of opening and closing.

[0072] It is understandable that there may be multiple groups of translation devices 3 to improve the translation stability of the cover plate 1. The number and location of the translation devices 3 may be adjusted according to the actual specifications of the cover plate 1, which will not be elaborated here.

[0073] Furthermore, the tooth pitch of the first rack 324 is not equal to the tooth pitch of the second rack 325. For example, the tooth pitch of the second rack 325 is greater than the tooth pitch of the first rack 324, so as to extend the movable distance of the cover plate 1 and save the space occupied by the first rack 324 and the second rack 325, so as to make the overall structure of the side-sliding hatch cover more compact and avoid interference between the second rack 325 and the hatch body 4.

[0074] See also Figure 1 The present invention also provides a ship, comprising a hatch body 4 and a side-sliding hatch cover, wherein a cover plate 1 is arranged on the hatch body 4. The hatch body 4 is provided with a clamp (not shown in the figure) and a stopper (not shown in the figure), and the depth of the stop groove 42 is greater than the depth of the guide rail 41, so that when the roller 11 is located in the stop groove 42, the cover plate 1 is limited.

[0075] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
