Description

Technical Field

[0001] This invention relates to the field of ship bridge hoisting technology, specifically a ship bridge hoisting device for entering the cabin. Background Technology

[0002] A ship's control console is a control device used above a ship to facilitate the control of the ship's direction and status. During the construction of the intelligent technology test ship, due to the short project cycle and heavy workload, the project construction plan required that the console be installed in the cabin before the roof of the bridge was put on.

[0003] The ship's bridge is an enclosed tower, surrounded entirely by floor-to-ceiling windows, making it inconvenient to drill process holes. Therefore, the control panels must be installed in advance. However, the bridge has numerous control panels, including the forward control panel, aft control panel, port wing control panel, starboard wing control panel, radio station, safety center control panel, test bench, and chart table. According to the manufacturer's normal schedule, delivery cannot be made on time, but the on-site assembly progress cannot be delayed. Therefore, an alternative solution is needed to lift the control panels into the bridge. Existing technology uses cranes for lifting, which is prone to swaying during transport due to unbalanced lifting ropes. Therefore, a ship's control panel loading and unloading device is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a hoisting device for the ship's bridge control, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hoisting device for entering the cabin of a ship's bridge, comprising a base plate, extended side plates, and a gantry frame. A winding shaft is rotatably connected to the opposite outer surfaces of the left and right sides of the gantry frame. Two winding wheels are fixedly sleeved on the outer surface of the winding shaft. A first motor is fixedly installed on the outer surface of the gantry frame, and the output end of the first motor is fixedly connected to the winding shaft. A hoisting rope is wound around the outer surface of the winding wheels, and a hook is fixedly connected to the other end of the hoisting rope. An adjusting cylinder is provided outside the hoisting rope. A support shaft rotatably passes through the outer surface of the adjusting cylinder. An adjusting wheel is fixedly sleeved on the outer surface of the support shaft. The hoisting rope movably passes through the upper and lower outer surfaces of the adjusting cylinder. The middle end of the hoisting rope inside the adjusting cylinder is fixed to the outer surface of the adjusting wheel. Two ratchet wheels are fixedly sleeved on the outer surface of the support shaft. Pads are rotatably connected to the inner surfaces of the left and right sides of the adjusting cylinder. The pawls engage with two adjacent teeth of the ratchet wheels. An adjusting rope is fixedly connected to the outer surface of the pawls, and the other end of the adjusting rope movably passes through the outer surface of the adjusting cylinder.

[0006] As a further explanation of the present invention, it also includes a vertical plate, a rotating seat fixedly connected to the front outer surface of the vertical plate, a rotating shaft rotatably passing through the outer surface of the rotating seat, a rotating block fixedly sleeved on the outer surface of the rotating shaft, the rotating block being fixedly connected to the extended side plate, a worm gear fixedly sleeved on the outer surface of the rotating shaft, a second motor fixedly mounted on the outer surface of the rotating seat, a worm fixedly connected to the output end of the second motor, and the worm engaging movably with the outer surface of the worm gear.

[0007] As a further explanation of the present invention, two fixing plates are fixedly connected to the bottom outer surface of the extended side plate, and a lead screw is rotatably connected between the two fixing plates. A third motor is fixedly installed on the outer surface of one of the fixing plates, and the output end of the third motor is fixedly connected to the lead screw. A threaded plate is threadedly connected to the outer surface of the lead screw, and the bottom outer surface of the threaded plate is fixedly connected to the gantry frame.

[0008] As a further illustration of the present invention, a scissor lift is fixedly installed on the top outer surface of the base plate, and the vertical plate is installed on the top outer surface of the scissor lift.

[0009] As a further explanation of the present invention, two hydraulic cylinders are fixedly installed on the bottom outer surface of the base plate, and a vacuum suction cup is fixedly installed at the output end of the hydraulic cylinder.

[0010] As a further explanation of the present invention, a counterweight plate is fixedly installed at the center of the bottom outer surface of the base plate.

[0011] As a further explanation of the present invention, the ratchet teeth of the two ratchet wheels are oriented in opposite directions.

[0012] As a further explanation of the present invention, a sliding rod is fixedly connected between the two fixed plates, and the threaded plate is movably sleeved on the outer surface of the sliding rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by using existing windows to bring the platform into the shipyard during the later stages of ship construction, the platform's entry into the shipyard can be delayed, allowing ample time for design and fabrication. This results in a higher level of platform integrity, more complete internal wiring, and easier modifications at the platform manufacturer should any discrepancies between the installed components and the drawings. Furthermore, it avoids the need to drill process holes in the hull structure later, which could damage the structure, allowing for a more gentle entry process. This resolves the contradiction of an earlier platform entry point but a later platform delivery date.

[0014] 2. In this invention, by pulling the corresponding adjusting rope, the corresponding pawl is disengaged from the adjacent ratchet, the ratchet is released from its limit, and the support shaft can rotate. The support shaft drives the adjusting wheel to rotate, adjusting the length of the suspension rope so that the platform is in a balanced state when it is lifted, thus enabling the platform to be transported more smoothly and avoiding collisions with the window opening during transport.

[0015] 3. In this invention, when no hoisting work is being performed, the second motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate, causing the extended side plate to rotate to a state parallel to the vertical plate, thereby retracting the extended side plate and facilitating the movement of the device in a small space.

[0018] 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.

[0019] Example 1: Please refer to the following: Figures 1-6This invention provides a technical solution: a hoisting device for entering the cabin of a ship's bridge, comprising a base plate 1, extended side plates 2, and a gantry frame 3. A winding shaft 4 is rotatably connected to the opposite outer surfaces of the left and right sides of the gantry frame 3. Two winding wheels 5 are fixedly sleeved on the outer surface of the winding shaft 4. A first motor 6 is fixedly installed on the outer surface of the gantry frame 3, and the output end of the first motor 6 is fixedly connected to the winding shaft 4. A lifting rope 7 is wound around the outer surface of the winding wheels 5, and a hook 9 is fixedly connected to the other end of the lifting rope 7. An adjusting cylinder 8 is provided outside the lifting rope 7, and a support shaft 10 rotatably passes through the outer surface of the adjusting cylinder 8. An adjusting wheel 11 is fixedly fitted on the outer surface of the support shaft 10. A suspension rope 7 movably passes through the upper and lower outer surfaces of the adjusting cylinder 8. The middle end of the suspension rope 7 inside the adjusting cylinder 8 is fixed to the outer surface of the adjusting wheel 11. Two ratchet wheels 12 are fixedly fitted on the outer surface of the support shaft 10. Pads 13 are rotatably connected to the inner surfaces of the left and right sides of the adjusting cylinder 8. The pads 13 mesh with two adjacent ratchet teeth of the ratchet wheels 12. An adjusting rope 14 is fixedly connected to the outer surface of the pads 13. The other end of the adjusting rope 14 movably passes through the outer surface of the adjusting cylinder 8. Specifically, the end of the extension side plate 2 away from the bottom plate 1 is extended into the inner part of the cockpit. The disassembled platform is secured using ropes. Hook 9 is attached to the ropes, and the platform is hoisted. The lengths of the two hoisting ropes 7 and the platform's tilt are observed. When the platform tilts, the support shaft 10 at the corresponding adjusting cylinder 8 is rotated. At this time, the designated adjusting rope 14 is pulled. The adjusting rope 14 pulls the pawl 13 upwards, causing the pawl 13 to disengage from the teeth of the ratchet 12, releasing the limit on the support shaft 10. This allows the support shaft 10 to rotate clockwise or counterclockwise. By pulling different adjusting ropes 14, the clockwise or counterclockwise direction of the support shaft 10 is limited. When the support shaft 10 rotates, it... The adjusting wheel 11 rotates, causing it to wind up or unwind the suspension rope 7 to a certain extent until the lengths of the two suspension ropes 7 are relatively consistent. After adjustment, the adjusting rope 14 is released, and the pawl 13, due to its own weight, gets stuck in the two adjacent ratchet teeth of the ratchet 12, limiting the ratchet 12 and thus limiting the support shaft 10, preventing the support shaft 10 from rotating. Then, the first motor 6 drives the winding shaft 4 to rotate, which in turn drives the winding wheel 5 to rotate, winding up the suspension rope 7 and lifting the platform. This allows the platform to be transported more smoothly, avoiding collisions with the window opening during transport.

[0020] In this embodiment, two fixed plates are fixedly connected to the bottom outer surface of the extended side plate 2, and a lead screw 26 is rotatably connected between the two fixed plates. A third motor 25 is fixedly installed on the outer surface of one of the fixed plates. The output end of the third motor 25 is fixedly connected to the lead screw 26. A threaded plate 27 is threadedly connected to the outer surface of the lead screw 26. The bottom outer surface of the threaded plate 27 is fixedly connected to the gantry frame 3. Specifically, the lead screw 26 is driven to rotate by the third motor 25. When the lead screw 26 rotates, it drives the threaded plate 27 to move. The movement of the threaded plate 27 moves the platform into the cockpit, and then the platform is lowered.

[0021] In this embodiment, a scissor lift 21 is fixedly installed on the top outer surface of the base plate 1, and a vertical plate 15 is installed on the top outer surface of the scissor lift 21. Specifically, by operating the scissor lift 21, the height of the extension side plate 2 is adjusted so that when the device is in use, the extension side plate 2 contacts the top of the window opening, thus saving as much hoisting space as possible below the window opening.

[0022] In this embodiment, two hydraulic cylinders 23 are fixedly installed on the bottom outer surface of the base plate 1. A vacuum suction cup 24 is fixedly installed at the output end of the hydraulic cylinder 23. Specifically, after the base plate 1 is moved to a suitable position in the ship, the hydraulic cylinder 23 works to drive the vacuum suction cup 24 to move downward, so that the vacuum suction cup 24 is adsorbed on the deck of the ship, increasing the stability of the device.

[0023] In this embodiment, a counterweight plate 22 is fixedly installed at the center of the bottom outer surface of the base plate 1. Specifically, by setting the counterweight plate 22 at the bottom of the base plate 1, the center of gravity of the device is located at the bottom of the base plate 1, so as to avoid the center of gravity of the entire device deviating when the platform is lifted, thus preventing the device from becoming unstable.

[0024] In this embodiment, the ratchet teeth of the two ratchet wheels 12 are oriented in opposite directions. Specifically, the ratchet teeth of the two ratchet wheels 12 are oriented in opposite directions, so that the locking direction of the pawl 13 on the ratchet wheels 12 is opposite. The two sets of ratchet wheels 12 simultaneously limit and lock the support shaft 10 in both clockwise and counterclockwise directions.

[0025] In this embodiment, a slide rod is fixedly connected between the two fixed plates, and the threaded plate 27 is movably sleeved on the outer surface of the slide rod. Specifically, when the lead screw 26 rotates, it drives the threaded plate 27 to move, so that the threaded plate 27 slides on the outer surface of the slide rod, so that the threaded plate 27 moves in a stable straight line, and avoids the threaded plate 27 from rotating with the lead screw 26.

[0026] In the specific implementation process, the device is moved to the center window on the front side of the cockpit. The end of the extended side plate 2 away from the bottom plate 1 is extended into the interior of the cockpit. The disassembled platform is fixed with ropes, and the hook 9 is hung on the ropes. The platform is then hoisted, and the lengths of the two hoisting ropes 7 and the tilt of the platform are observed. When the platform tilts, the support shaft 10 at the corresponding adjusting cylinder 8 is rotated. At this time, the designated adjusting rope 14 is pulled. The adjusting rope 14 drives the pawl 13 to pull upward, causing the pawl 13 to disengage from the teeth of the ratchet 12, releasing the limit on the support shaft 10, allowing the support shaft 10 to rotate clockwise or counterclockwise. By pulling different adjusting ropes 14, the clockwise or counterclockwise direction of the support shaft 10 is limited. When the support shaft 10 rotates, it drives the adjusting wheel 11. The adjustment wheel 11 rotates, causing the lifting rope 7 to be wound or unwound to a certain extent until the lengths of the two lifting ropes 7 are relatively consistent. After adjustment, the adjustment rope 14 is released, and the pawl 13, due to its own weight, gets stuck in the two adjacent ratchet teeth of the ratchet 12, limiting the ratchet 12 and thus limiting the support shaft 10, preventing the support shaft 10 from rotating. Then, the first motor 6 drives the winding shaft 4 to rotate, which in turn drives the winding wheel 5 to rotate, winding the lifting rope 7 and lifting the platform. The third motor 25 drives the lead screw 26 to rotate, which in turn drives the threaded plate 27 to move. The movement of the threaded plate 27 moves the platform into the cockpit, and then the platform is lowered. This allows for relatively stable transport of the platform, avoiding collisions with the window openings during transport.

[0027] In actual use, for example, after checking the dimensions of the entire cab's floor-to-ceiling windows, it was found that the two windows in the center front and rear of the cab are the largest, and both are rectangular. The opening size of the enclosure on the steel structure is 2480x2072mm. After checking the front control console, the platform can be removed from the base. The widest part is 1100mm wide and 1208mm high. The rear control part is 1027mm wide and 1660mm high. The radio part is 900mm wide and 1308mm high. The safety center part is 900mm wide and 1308mm high. The two wing platforms are 860mm wide and 1284mm high. The test platform is 906mm wide and 868mm high. According to these calculations, all platforms can pass smoothly through the window openings. By utilizing existing windows, the platform can be installed in the shipyard during the mid-to-late stages of shipbuilding. This allows for a later installation time, providing ample time for platform design and fabrication, resulting in greater integrity and more complete internal wiring. Furthermore, any discrepancies between the installed components and the drawings are easier to correct at the platform manufacturer. It also avoids the need to drill process holes in the hull structure later, which could damage the structure, allowing for a more gentle installation. This resolves the contradiction of an earlier platform installation but a later delivery date.

[0028] Example 2: Please refer to the following: Figures 1-6 The present invention provides a technical solution: it further includes a vertical plate 15, a rotating seat 16 is fixedly connected to the front outer surface of the vertical plate 15, a rotating shaft is rotatably passed through the outer surface of the rotating seat 16, a rotating block 17 is fixedly sleeved on the outer surface of the rotating shaft, the rotating block 17 is fixedly connected to the extended side plate 2, a worm gear 18 is fixedly sleeved on the outer surface of the rotating shaft, a second motor 19 is fixedly installed on the outer surface of the rotating seat 16, a worm 20 is fixedly connected to the output end of the second motor 19, and the worm 20 is movably meshed with the outer surface of the worm gear 18. Specifically, when not hoisting, the second motor 19 works, drives the worm 20 to rotate, the worm 20 drives the worm gear 18 to rotate, and when the worm gear 18 rotates, it drives the rotating block 17 to rotate, so that the extended side plate 2 moves to a position parallel to the vertical plate 15, and the extended side plate 2 is retracted, which facilitates the movement of the device in a small space.

[0029] In the specific implementation process, when not hoisting, the second motor 19 operates, driving the worm 20 to rotate. The worm 20 drives the worm wheel 18 to rotate, and the rotation of the worm wheel 18 drives the rotating block 17 to rotate, causing the extension side plate 2 to move to a position parallel to the vertical plate 15, thus retracting the extension side plate 2. This facilitates the movement of the device in a small space. The relationship between the rotation angle of the worm wheel 18 and the rotation angle of the worm 20 is: θ=N*360*z1 / z2, where z1 and z2 are the number of worm heads and the number of teeth of the worm wheel 18, respectively, and N is the number of motor rotations. For example, taking the common "single-head worm 20 + 40-tooth worm wheel 18" as an example, z1=1, z2=40. If the motor rotates the base plate 1 revolution, N=1, then the rotation angle of the worm wheel 18 is 1*360*1 / 40=9°.

[0030] Working Principle: In use, the device is moved to the center window at the front of the cockpit. The end of the extended side plate 2 away from the bottom plate 1 is extended into the cockpit. The disassembled platform is fixed with ropes, and the hook 9 is hung on the ropes. The platform is then lifted, and the lengths of the two suspension ropes 7 and the tilt of the platform are observed. When the platform tilts, the support shaft 10 at the corresponding adjusting cylinder 8 is rotated. At this time, the designated adjusting rope 14 is pulled. The adjusting rope 14 drives the pawl 13 to pull upward, causing the pawl 13 to disengage from the teeth of the ratchet 12, releasing the restriction on the support shaft 10. This allows the support shaft 10 to rotate clockwise or counterclockwise. By pulling different adjusting ropes 14, the clockwise or counterclockwise direction of the support shaft 10 is limited. When the support shaft 10 rotates, it drives the adjusting wheel. Rotating the adjustment wheel 11 causes the lifting rope 7 to be wound or unwound to a certain extent until the lengths of the two lifting ropes 7 are relatively consistent. After adjustment, the adjustment rope 14 is released. The pawl 13, due to its own weight, is stuck in the two adjacent ratchet teeth of the ratchet 12, limiting the ratchet 12 and thus limiting the support shaft 10, preventing the support shaft 10 from rotating. Then, the first motor 6 drives the winding shaft 4 to rotate, which in turn drives the winding wheel 5 to rotate, winding the lifting rope 7 and lifting the platform. The third motor 25 drives the lead screw 26 to rotate. When the lead screw 26 rotates, it drives the threaded plate 27 to move. The movement of the threaded plate 27 moves the platform into the cockpit, and then the platform is lowered. This allows for relatively stable transport of the platform, avoiding collisions with the window openings during transport. By utilizing existing windows, the platform can be installed in the shipyard during the mid-to-late stages of shipbuilding. This allows for a later installation time, providing ample time for platform design and fabrication, resulting in greater integrity and more complete internal wiring. Furthermore, any discrepancies between the installed components and the drawings are easier to correct at the platform manufacturer. It also avoids the need to drill process holes in the hull structure later, which could damage the structure, allowing for a more gentle installation. This resolves the contradiction of an earlier platform installation but a later delivery date.

[0031] When not in use for hoisting, the second motor 19 operates, driving the worm 20 to rotate. The worm 20 then drives the worm wheel 18 to rotate, which in turn drives the rotating block 17 to rotate. This causes the extended side plate 2 to move to a position parallel to the vertical plate 15, allowing the extended side plate 2 to be retracted. This facilitates the movement of the device in a small space. The relationship between the rotation angle of the worm wheel 18 and the rotation angle of the worm 20 is: θ = N * 360 * z1 / z2, where z1 and z2 are the number of worm heads and the number of teeth of the worm wheel 18, respectively, and N is the number of motor rotations. For example, taking the common "single-head worm 20 + 40-tooth worm wheel 18" as an example, z1 = 1, z2 = 40. If the motor rotates the base plate 1 revolution, N = 1, then the rotation angle of the worm wheel 18 is 1 * 360 * 1 / 40 = 9°.
