Description

Technical Field

[0001] This utility model relates to the field of bulk carrier hatch cover technology, specifically an electric remote-controlled hatch cover device for bulk carriers. Background Technology

[0002] Bulk carriers, also known as dry bulk carriers or bulk cargo ships, are vessels that transport large quantities of bulk cargo (usually including ores, coal, cement, and other such bulk cargoes). After the cargo is loaded, hatch covers are installed on the top of the bulk carrier's holds to seal the hatches and prevent the cargo from being corroded by rainwater.

[0003] Due to the large size of bulk carriers, the hatch covers that are installed are quite heavy, making it inconvenient to manually handle and control the opening and closing of the hatch covers. Therefore, electric remote control devices are usually installed on the hatch covers to control the opening and closing of the hatch covers through mechanical drive. However, after the hatch covers are opened, the lack of a limiting structure makes the hatch covers less stable and poses certain safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide an electric remote-controlled hatch cover device for bulk carriers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric remote-controlled hatch cover device for a bulk carrier, comprising a bulk carrier hold, side frames fixedly connected to the front and rear sides of the bulk carrier hold, a connecting frame fixedly connected to the side of the side frames away from the bulk carrier hold, a sliding rod slidably connected inside the connecting frame, a limit plate fixedly connected to the end of the sliding rod away from the side frame, a return spring movably sleeved on the surface of the sliding rod, a baffle provided on the side of the return spring away from the connecting frame, the baffle fixedly connected to the surface of the sliding rod, a first motor fixedly connected to the inner wall of the side frame, a connecting shaft fixedly connected to the output end of the first motor, and a rotating plate fixedly sleeved on the surface of the connecting shaft.

[0006] As a further preferred embodiment of this technical solution, two connecting frames are provided, and the two connecting frames adopt an L-shaped structure. The reset spring is located between the connecting frame and the baffle, and the baffle is in contact with the rotating plate.

[0008] As a further preferred embodiment of this technical solution, the number of guide grooves is four, the number of hydraulic cylinders corresponds to the number of guide grooves, and the support plate is adapted to the guide grooves.

[0009] As a further preferred embodiment of this technical solution, a first hatch cover is provided at the top of the bulk carrier hold, a second hatch cover is provided at the top of the bulk carrier hold, sealing gaskets are provided at the bottom of the second hatch cover and the first hatch cover, rollers are rotatably connected to the front and rear sides of the second hatch cover and the first hatch cover, and positioning frames are fixedly connected to the front and rear sides of the second hatch cover and the first hatch cover.

[0010] As a further preferred embodiment of this technical solution, the bottom of the second hatch and the first hatch are provided with grooves, the inner wall of the groove is fixedly connected with a rack plate, a second motor is provided inside the groove, the second motor is fixedly connected to the top of the side frame, and the output shaft of the second motor is fixedly sleeved with a rotating gear.

[0011] As a further preferred embodiment of this technical solution, two grooves are provided, the thickness of the rack plate is greater than that of the rotating gear, and the rack plate and the rotating gear mesh.

[0012] As a further preferred embodiment of this technical solution, a locking block is fixedly connected to the top of the first hatch, and mounting grooves are provided on the front and rear sides of the locking block.

[0013] This utility model provides an electrically controlled remote hatch cover device for bulk carriers, which has the following advantages:

[0014] (1) After the hatch cover is opened, the positioning frame corresponds to the connecting frame. At this time, the first motor is started, and its output shaft drives the connecting shaft to rotate. The rotating plate rotates and separates from the baffle. Due to the lack of limit, the reset spring rebounds and pushes the baffle closer to the positioning frame. The slide rod slides on the connecting frame and is locked inside the positioning frame, thereby fixing the position of the hatch cover and preventing it from sliding.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, an electric remote-controlled hatch cover device for a bulk carrier includes a bulk carrier hold 1. Side frames 2 are fixedly connected to the front and rear sides of the bulk carrier hold 1. A connecting frame 3 is fixedly connected to the side of the side frame 2 away from the bulk carrier hold 1. A sliding rod 4 is slidably connected inside the connecting frame 3. A limit plate 5 is fixedly connected to the end of the sliding rod 4 away from the side frame 2. A return spring 6 is movably sleeved on the surface of the sliding rod 4. A baffle 7 is provided on the side of the return spring 6 away from the connecting frame 3. The baffle 7 is fixedly connected to the surface of the sliding rod 4. A first motor 8 is fixedly connected to the inner wall of the side frame 2. A connecting shaft 9 is fixedly connected to the output end of the first motor 8. A rotating plate 10 is fixedly sleeved on the surface of the connecting shaft 9.

[0024] By setting a photoelectric sensor on the slide rod 4, the position of the positioning frame 20 is detected. When the positioning frame 20 corresponds to the connecting frame 3, the first motor 8 works, and its output shaft drives the connecting shaft 9 to rotate. The rotating plate 10 rotates accordingly and separates from the baffle 7. Due to the lack of a limit, the return spring 6 rebounds and pushes the baffle 7 closer to the positioning frame 20. The slide rod 4 slides on the connecting frame 3 and engages inside the positioning frame 20, thereby realizing the automatic limit of the hatch cover to ensure the stability of the hatch cover after opening. When it is necessary to release the restriction of the hatch cover, the first motor 8 drives the rotating plate 10 to reverse and squeezes the return spring 6. The slide rod 4 disengages from the positioning frame 20, and the hatch cover can be moved.

[0025] There are two connecting frames 3, and the two connecting frames 3 adopt an L-shaped structure. The return spring 6 is located between the connecting frame 3 and the baffle 7, and the baffle 7 is in contact with the rotating plate 10.

[0026] The top of the side frame 2 is provided with a guide groove 11, the inner wall of the side frame 2 is fixedly connected with a hydraulic cylinder 12, the top of the hydraulic cylinder 12 is fixedly connected with a support plate 13, the top of the support plate 13 is fixedly connected with a connecting guide rail 14, and the top of the side frame 2 is fixedly connected with a moving guide rail 15.

[0027] There are four guide grooves 11, the number of hydraulic cylinders 12 corresponds to the number of guide grooves 11, and the support plate 13 is adapted to the guide grooves 11.

[0028] The top of the bulk carrier hold 1 is provided with a first hatch cover 16, and the top of the bulk carrier hold 1 is provided with a second hatch cover 17. The bottom of the second hatch cover 17 and the first hatch cover 16 are provided with sealing gaskets 18. The front and rear sides of the second hatch cover 17 and the first hatch cover 16 are rotatably connected with rollers 19, and the front and rear sides of the second hatch cover 17 and the first hatch cover 16 are fixedly connected with positioning frames 20.

[0029] By adopting a split structure for the connecting guide rail 14 and the moving guide rail 15, the hydraulic cylinder 12 can easily control the height of the first hatch cover 16 and the second hatch cover 17. When the first hatch cover 16 and the second hatch cover 17 are closed, the hydraulic cylinder 12 drives the support plate 13 and the connecting guide rail 14 to move downward in the guide groove 11, and the roller 19 moves into the guide groove 11, thereby limiting the first hatch cover 16 and the second hatch cover 17. At the same time, the first hatch cover 16 and the second hatch cover 17 contact the bulk carrier hold 1, and the sealing gasket 18 is used to ensure the sealing of the connection to reduce the entry of rainwater, dust, etc. When it is necessary to open the first hatch cover 16 and the second hatch cover 17, the hydraulic cylinder 12 pushes the support plate 13 upward, the connecting guide rail 14 and the moving guide rail 15 are connected as one unit, and the roller 19 moves out of the guide groove 11, thereby facilitating the movement of the first hatch cover 16 and the second hatch cover 17.

[0030] The bottom of the second hatch 17 and the first hatch 16 are provided with a groove 21. A rack plate 22 is fixedly connected to the inner wall of the groove 21. A second motor 23 is provided inside the groove 21. The second motor 23 is fixedly connected to the top of the side frame 2. A rotating gear 24 is fixedly sleeved on the output shaft of the second motor 23.

[0031] When the second motor 23 is started, its output shaft drives the rotating gear 24 to rotate. Since the rack plate 22 and the rotating gear 24 are meshed, the rack plate 22 drives the first hatch cover 16 and the second hatch cover 17 to move closer to or further away from each other, thereby facilitating the opening and closing of the hatch cover. Moreover, the thickness of the rack plate 22 is greater than that of the rotating gear 24. After the first hatch cover 16 and the second hatch cover 17 move up and down, the rack plate 22 and the rotating gear 24 can always maintain a meshed state to ensure their normal operation.

[0032] There are two grooves 21. The thickness of the rack plate 22 is greater than that of the rotating gear 24. The rack plate 22 and the rotating gear 24 mesh.

[0033] The top of the first hatch 16 is fixedly connected to a locking block 25. The front and rear sides of the locking block 25 are provided with mounting grooves 26. The inner wall of the mounting groove 26 is fixedly connected to a connecting spring 27. The mounting groove 26 is provided with a positioning ball 28. The front and rear sides of the locking block 25 are provided with locking seats 29. The locking seats 29 are fixedly connected to the second hatch 17. The side of the locking seat 29 near the locking block 25 is provided with a positioning groove 30. The positioning ball 28 is engaged inside the positioning groove 30.

[0034] When the first hatch 16 and the second hatch 17 are closed, the locking block 25 slides inside the locking seat 29. Due to the compression of the locking seat 29, the positioning ball 28 moves into the mounting groove 26, and the connecting spring 27 is compressed and contracted. When the end faces of the first hatch 16 and the second hatch 17 contact, the connecting spring 27 rebounds and drives the positioning ball 28 to move inside the mounting groove 26. The positioning ball 28 is engaged in the positioning groove 30, thereby reinforcing the connection between the first hatch 16 and the second hatch 17 and ensuring the stability after closure.

[0035] This utility model provides an electrically controlled remote hatch cover device for bulk carriers, the specific working principle of which is as follows:

[0036] In operation, the hydraulic cylinder 12 is activated, and its output rod pushes the support plate 13 and the connecting guide rail 14 upward. The roller 19, the first hatch cover 16, and the second hatch cover 17 move accordingly. The rack plate 22 and the rotating gear 24 slide longitudinally. When the tops of the connecting guide rail 14 and the moving guide rail 15 are on the same plane, the roller 19 moves out of the guide groove 11, the hydraulic cylinder 12 stops working, and the second motor 23 is activated. Its output shaft drives the rotating gear 24 to rotate. Because the rack plate 22 and the rotating gear 24 mesh, the rack plate 22 drives the first hatch cover 16 and the second hatch cover 17 to move away from each other. As the roller 19 moves in the direction of the position, it slides on the combined guide rail. The positioning ball 28 disengages from the positioning groove 30, allowing the hatch cover to be opened. When the positioning frame 20 aligns with the connecting frame 3, the first motor 8 is started, and its output shaft drives the connecting shaft 9 to rotate. The rotating plate 10 rotates accordingly and separates from the baffle 7. Due to the lack of a limit switch, the return spring 6 rebounds and pushes the baffle 7 closer to the positioning frame 20. The sliding rod 4 slides on the connecting frame 3 and engages inside the positioning frame 20, thus fixing the positions of the first hatch cover 16 and the second hatch cover 17 to facilitate loading and unloading of bulk carriers.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
