Description

Technical Field

[0001] This invention relates to the field of marine ceiling technology, specifically to a marine lifting ceiling assembly. Background Technology

[0002] Simply put, a suspended ceiling refers to the decoration of the ceiling, which is an important part of interior decoration.

[0003] The ceiling structure mainly uses a keel as a frame and then assembles the panels. In ships such as cruise ships, the conventional ceiling keel base is hoisted by a large crane using suspension rods to realize the ceiling keel system, thereby fixing the ceiling to the top layer. However, this method is not only troublesome to fix, but also makes it impossible to install the ceiling. When the transportation system inside the ceiling malfunctions and needs to be repaired, the ceiling also needs to be disassembled, which is not only very troublesome, but may also cause damage to the ceiling.

[0004] Therefore, the ceilings of ship cabins generally have raised or lowered areas. However, traditional ceiling profiles do not have the function of raising or lowering. If the connection between the raised or lowered areas of the ceiling is not handled properly, it will affect the overall visual effect of the cabin ceiling, as well as the overall reliability, safety, fire resistance and other performance of the cabin. Therefore, a ship ceiling raised or lowered ceiling profile was invented. This profile is used for connecting the raised or lowered areas of the ceiling. Summary of the Invention

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] I. This invention uses an electric push rod to press the pressure plate against the upper surface of the horizontal end of the L-shaped plate, thereby achieving the purpose of clamping and fixing the ceiling, making the ceiling more stable in this ceiling assembly, and making the ceiling more difficult to move during subsequent vertical movement. Furthermore, the setting of four sets of stabilizing plates can further improve the clamping and stabilizing effect of the ceiling, further improving the stability of this ceiling assembly. Also, by having the four stabilizing plates close to the pressure plate when not pressing, the space for installing the ceiling is further increased, making this ceiling assembly more convenient for ceiling installation.

[0027] Second, this invention automatically identifies the ceiling when installing it on the ceiling assembly, thereby reducing the time required for installers to manually activate the electric push rod. Furthermore, when removing the ceiling, simply turning the threaded rod releases the pressure lock on the ceiling, making ceiling removal very convenient and further improving the practicality of this ceiling assembly.

[0028] Third, this invention achieves the alignment of two ceiling panels by moving straight toothed racks one and two in different directions, thereby driving the ceiling panels on L-shaped plates one and two to move to the same height. This makes the ceiling installation neater and more aesthetically pleasing. Furthermore, since the two ceiling panels move in different directions during alignment, the alignment or unfolding time is accelerated. In case of emergency, the two ceiling panels can be opened more quickly, creating an opening that allows fire-fighting equipment on the upper part of the two ceiling panels to function more rapidly, further improving the practical effect of this device.

[0029] Fourth, this invention changes the distance between the ceiling and the steel frame by moving the straight toothed rack three up and down, which in turn drives the L-shaped plate one and L-shaped plate two up and down. This allows the ceiling assembly to increase the interior space by moving the ceiling upwards, or to increase the distance between the ceiling and the steel frame by moving the ceiling downwards. This makes it easier to maintain the safety protection device between the ceiling and the steel frame, and further improves the practicality of the ceiling assembly. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1:

[0040] Please see Figures 1 to 7 This embodiment provides a technical solution: a marine lifting ceiling assembly includes a steel frame plate 1 and a ceiling 5, the ceiling 5 being disposed below the steel frame plate 1, and an L-shaped plate 4 and an L-shaped plate 6 being disposed below the steel frame plate 1. The marine lifting ceiling assembly also includes:

[0041] A pressure-fixing component is installed on L-shaped plate 4;

[0042] The pressure fixing components include:

[0043] The fixed block 9 has its end face fixedly connected to the vertical end surface of the L-shaped plate 4. An electric push rod 29 is fixedly connected to the lower surface of the fixed block 9. A transmission plate 10 is fixedly connected to the output end of the electric push rod 29. A spline sleeve 18 is fixedly connected to the other end of the transmission plate 10. A connecting block 20 is fixedly connected to the outer surface of the spline sleeve 18. A spline rod 11 is slidably connected to the inner wall of the spline sleeve 18. A pressure plate 14 is fixedly connected to the lower surface of the spline rod 11. A top plate 22 is also fixedly connected to the upper end face of the spline rod 11. Four sets of through sliding grooves 21 are opened on the upper surface of the top plate 22.

[0044] A first curved rod 19 is hinged at one end to the upper surface of the connecting block 20, and a pressure rod 16 is hinged at the other end of the first curved rod 19. A second curved rod 17 is also hinged at the lower surface of the pressure rod 16, and the other end of the second curved rod 17 is hinged to the lower surface of the connecting block 20. A stabilizing plate 15 is fixedly connected to the lower surface of the pressure rod 16, and the upper surface of the pressure rod 16 is slidably connected to the wall of the sliding groove 21. A limit plate 23 is also fixedly connected to the upper surface of the pressure rod 16.

[0045] More specifically, in this embodiment: when using this ceiling assembly, firstly, the ceiling assembly is installed on the steel frame plate 1 at the top of the ship, and then the ceiling 5 is placed between the L-shaped plate 4 and the pressure plate 14. When the presence of the ceiling 5 between the L-shaped plate 4 and the pressure plate 14 is detected, the electric push rod 29 will be activated. The operation of the electric push rod 29 will further drive the transmission plate 10 to move downward, thereby driving the spline sleeve 18 to move downward, which will further enable the pressure fixing assembly to have the following two movement states:

[0046] Firstly, when the pressure plate 14 is not in contact with the ceiling 5, due to gravity, the top plate 22 will be in close contact with the upper surface of the spline sleeve 18, so that the spline rod 11 will descend together with the spline sleeve 18, thereby further driving the pressure plate 14 and the stabilizing plate 15 to continue to descend towards the ceiling 5, thus reducing the distance between the L-shaped plate 4 and the pressure plate 14.

[0047] Secondly, when the pressure plate 14 comes into contact with the ceiling 5, the support of the ceiling 5 will stop the pressure plate 14 from moving. This will cause the spline sleeve 18 to continue to descend without moving the spline rod 11. As the spline sleeve 18 continues to descend, the distance between the spline sleeve 18 and the top plate 22 will further increase, causing the first crank rod 19 and the second crank rod 17 to deflect. Then, the pressure rod 16 will move outward in the sliding groove 21, further increasing the distance between the four stabilizing plates 15. This will increase the pressure area on the ceiling 5. Since the pressure rod 16 can only move horizontally in the sliding groove 21 and cannot move up and down, the pressure effect on the ceiling 5 can be further improved.

[0048] The clamping and fixing assembly uses an electric push rod 29 to press the pressure plate 14, thereby pressing the ceiling 5 against the upper surface of the horizontal end of the L-shaped plate 4, thus achieving the purpose of clamping and fixing the ceiling 5. This makes the ceiling 5 more stable in the ceiling assembly and makes it more difficult for the ceiling 5 to move during subsequent vertical movement. Furthermore, the four sets of stabilizing plates 15 further enhance the clamping and stabilizing effect of the ceiling 5, further improving the stability of the ceiling assembly. When not pressing, the four stabilizing plates 15 are close to the pressure plate 14, further increasing the space for installing the ceiling 5, making it easier to install the ceiling 5.

[0049] It is worth noting that this embodiment also includes: a triggering component, which is disposed on the L-shaped plate 4;

[0050] Triggering components include:

[0051] Press plate 24, with spring 27 fixedly connected to the lower end face of press plate 24. The lower end of spring 27 is fixedly connected to the upper surface of the horizontal end of L-shaped plate 4. A threaded groove penetrating the upper surface of the horizontal end of L-shaped plate 4 is provided below press plate 24. A threaded rod 26 is threadedly connected to the groove wall. A press switch 28 is fixedly connected to the upper end face of threaded rod 26. A limit plate 25 is also fixedly connected to the lower end face of threaded rod 26.

[0052] More specifically, in this embodiment: when the ceiling 5 is placed on the L-shaped plate 4, the L-shaped plate 4 will press down on the pressing plate 24 under the action of gravity. Pressing down on the pressing plate 24 will press the pressing switch 28 below the pressing plate 24, thereby causing the electric push rod 29 to operate and achieve the pressing and fixing of the ceiling 5.

[0053] When it is necessary to remove the ceiling 5, simply rotate the threaded rod 26 to move the push switch 28 downward, so that the push switch 28 is not pressed, which will send a command to the electric push rod 29 to drive the anti-fixing component to return to its original position and release the fixation of the ceiling 5.

[0054] The trigger component is designed to automatically identify the ceiling 5 when it is installed on the ceiling assembly, thereby reducing the time required for installers to manually activate the electric push rod 29. Furthermore, when removing the ceiling 5, simply rotating the threaded rod 26 is sufficient to release the pressure lock on the ceiling 5, making the removal of the ceiling 5 very convenient and further improving the practicality of the ceiling assembly.

[0055] Example 2:

[0056] Based on the above embodiments:

[0057] Please see Figure 4 and Figure 5 In this embodiment, a distance changing component is included, which is disposed on the steel frame plate 1;

[0058] The distance change component includes:

[0059] A toothed ring 31 is meshed with a straight toothed row 3 on the side of the toothed ring 31 near the L-shaped plate 4. The back tooth surface of the straight toothed row 3 is fixedly connected to the vertical end surface of the L-shaped plate 4. A straight toothed row 7 is meshed with the tooth surface of the toothed ring 31 near the L-shaped plate 6. The back tooth surface of the straight toothed row 7 is fixedly connected to the vertical end surface of the L-shaped plate 6. A rotating rod 30 is also fixedly connected to the inner wall of the toothed ring 31.

[0060] The equipment box 34 contains a motor 37, and a straight toothed rack 36 is fixedly connected to the outer side of the equipment box 34. The end of the rotating rod 30 away from the toothed ring 31 rotates through the side of the equipment box 34 facing the toothed ring 31, and the end face of the rotating rod 30 away from the toothed ring 31 is fixedly connected to the output end face of the motor 37.

[0061] Both the upper end face of the first straight toothed rack 3 and the upper end face of the second straight toothed rack 7 are provided with through slots. The slot wall of the through slot of the first straight toothed rack 3 is slidably connected to a limiting rod 2, and the upper end face of the limiting rod 2 is fixedly connected to the lower surface of the steel frame plate 1. The slot wall of the through slot of the second straight toothed rack 7 is slidably connected to a limiting rod 8, and the upper end face of the limiting rod 8 is fixedly connected to the lower surface of the steel frame plate 1.

[0062] More specifically, in this embodiment: In this distance changing component, after the ceiling 5 is installed on L-shaped plate 4 and L-shaped plate 6, since L-shaped plate 4 and L-shaped plate 6 form a Z-shape, after installation, the ceiling 5 on L-shaped plate 4 and L-shaped plate 6 needs to be on the same horizontal plane. By starting motor 37 to rotate, the rotation of motor 37 will further drive the rotating rod 30 to rotate. The rotation of rotating rod 30 will cause the gear ring 31 to rotate, which will cause the straight gear row 3 and straight gear row 7 to move. By the straight gear row 3 moving downward and the straight gear row 7 moving upward, the ceiling 5 on L-shaped plate 4 and L-shaped plate 6 can be moved to the same height.

[0063] The distance-changing component is designed to move straight toothed racks 3 and 2 in different directions, thereby driving the ceiling panels 5 on L-shaped plates 4 and 6 to move to the same height, achieving alignment of the two ceiling panels 5. This makes the ceiling installation neater and more aesthetically pleasing. Furthermore, since the two ceiling panels 5 move in different directions during alignment, the alignment or unfolding time is accelerated. In case of emergency, the two ceiling panels 5 can open more quickly, creating an opening that allows fire-fighting equipment on top of the ceiling panels 5 to function more rapidly, further improving the practicality of the device.

[0064] Example 3:

[0065] Based on the above embodiments:

[0066] Please see Figure 5 , Figure 6 and Figure 7 In this embodiment, it also includes an overall height changing component, which is disposed on the steel frame plate 1.

[0067] The overall height changing components include:

[0068] Gear ring 2 33, the tooth surface of gear ring 2 33 meshes with the tooth surface of straight gear row 3 36. Rotating rod 2 32 is fixedly connected to the inner wall of gear ring 2 33. Connecting plate 40 is rotatably connected to the surface of rotating rod 2 32. Steel corner block 41 is fixedly connected to the upper end of connecting plate 40. The upper surface of steel corner block 41 is fixedly connected to the lower surface of steel frame plate 1. Limiting frame 39 is fixedly connected to the side of steel corner block 41. The groove wall of limiting frame 39 is slidably connected to the adjacent tooth surface of straight gear row 3 36. Support plate 38 is also fixedly connected to the side of steel corner block 41. Motor 2 42 is provided on the upper surface of support plate 38. Transmission rod 35 is fixedly connected to the output end of motor 2 42. Belt drive is applied to the surface of rotating rod 2 32.

[0069] More specifically, in this embodiment: starting the second motor 42 to rotate will further drive the transmission rod 35 to rotate. The rotation of the transmission rod 35 will drive the second rotating rod 32 to rotate through the leather, which will further cause the second gear ring 33 to rotate. This will cause the second gear ring 33 to roll on the tooth surface of the third straight gear row 36, causing the third straight gear row 36 to move up and down, which will further drive the equipment box 34 to move up and down, thereby causing the first L-shaped plate 4 and the second L-shaped plate 6 to move up and down, changing the distance between the ceiling 5 and the steel frame plate 1.

[0070] The overall height-changing component is designed to change the distance between the ceiling 5 and the steel frame plate 1 by moving the straight toothed rack 36 up and down, which in turn moves the L-shaped plate 4 and L-shaped plate 2 6 up and down. This allows the ceiling component to increase the interior space by moving the ceiling 5 upwards, or to increase the distance between the ceiling 5 and the steel frame plate 1 by moving the ceiling 5 downwards. This makes it easier to inspect and maintain the safety protection device between the ceiling 5 and the steel frame plate 1, and further improves the practicality of the ceiling component.

[0071] Example 4:

[0072] Based on the above embodiments:

[0073] Please see Figure 2 In this embodiment, the L-shaped plate 4 has a rounded corner block 13 fixedly connected to the horizontal end away from the vertical end, and a leveling block 12 fixedly connected to the horizontal end of the L-shaped plate 4 near the vertical end. The upper surface of the L-shaped plate 6 is also provided with rounded corner blocks 13 and leveling blocks 12.

[0074] More specifically, in this embodiment: the rounded corner block 13 makes the edge of the L-shaped plate 4 smoother, so that workers will not be injured by the cut edges of the L-shaped plate 4 when installing the ceiling 5, thus further improving the safety performance of this ceiling component. Furthermore, a leveling block 12 is also provided on the L-shaped plate 4, which further enables the ceiling 5 to remain in a horizontal state after being pressed by the pressure fixing component, thereby further improving the installation effect of the ceiling using this ceiling component.

[0075] Working principle: This marine lifting ceiling assembly has the following steps when in use:

[0076] S1: First, install this ceiling assembly onto the steel frame plate 1 at the top of the ship, and then place the ceiling 5 between the L-shaped plate 4 and the pressure plate 14.

[0077] S2: Next, the ceiling 5 presses the pressing plate 24, which causes the pressing plate 24 to press the pressing switch 28 below, causing the electric push rod 29 to operate.

[0078] S3: The operation of the electric push rod 29 will cause the pressure fixing component to operate, so that the pressure plate 14 and the stabilizing plate 15 abut against the upper surface of the ceiling 5.

[0079] S4: Then, by moving the ceiling 5 on motor 137L-shaped plate 14 and L-shaped plate 26 to the same height, the two ceiling 5 are aligned.

[0080] S5: Finally, by starting motor 42, the L-shaped plate 4 and L-shaped plate 6 are moved up and down as a whole, so that the ceiling 5 is at an appropriate height.

[0081] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
