Description

Technical Field

[0001] This invention relates to the field of cruise ship structures, and in particular to a cruise ship roof lifting system. Background Technology

[0002] When ships sail on water, they are affected by gusts of wind and waves, causing them to rise and fall and sway. For some cruise ships with retractable roofs, the large roof area and the fact that the roof will disrupt the streamline of the ship to some extent when it is raised will exacerbate the swaying of the ship.

[0003] When the ship is rocking and the roof needs to be raised or lowered, if lateral winds compress the lifting rod during the raising and lowering operation, the frictional resistance in the lifting direction will increase sharply, often causing the machine to freeze or jam. In this case, the excessive load on the drive unit can easily lead to burnout. Furthermore, because the ship's hull rises and falls with the waves, the load on the drive unit when driving the roof fluctuates, and the acceleration changes constantly, creating irregular impact forces on the drive unit. This not only increases the difficulty of controlling the roof raising and lowering but also accelerates the aging of the drive unit.

[0004] The traditional method uses accelerometers to monitor the condition of the roof and adjust the driving force of the drive unit in real time. This method is not only expensive in terms of hardware, but also, because the actual condition of the hull is complex and random, if the response speed is not fast enough, it will not only fail to solve the impact on the drive unit, but will also increase the damage to the drive unit. Summary of the Invention

[0008] In the preferred embodiment, one end of the canopy is fitted to the outer wall of the extension plate pivot, and a sealing strip is provided inside the end of the canopy at the fitting point.

[0009] In a preferred embodiment, the lifting rod assembly further includes a lead screw and a nut sleeved on the lead screw. The ceiling drive system drives the lead screw to rotate.

[0011] In a preferred embodiment, the telescopic rod assembly includes at least three sector-shaped rods, the ends of which are connected sequentially to form a cylindrical structure. The sleeve also contains at least three sector-shaped sliding plates, the ends of which are connected sequentially to form a cylindrical structure. The sleeve and the sector-shaped sliding plates are slidably connected. One end of each sector-shaped sliding plate is connected to its respective sector-shaped rod. Multiple first buffer springs are provided, with their ends respectively abutting against the sleeve and each sector-shaped sliding plate. Each sector-shaped rod has a conical head at its upper end and a top connecting sleeve. The top connecting sleeve is connected to the frame body. Multiple conical holes are provided inside the top connecting sleeve, with each conical head fitting into its respective conical hole. A countersunk portion is provided at the end of the top connecting sleeve closest to the frame body.

[0012] In the preferred embodiment, a limiting pin is also provided. Multiple limiting pins are provided inside the countersunk hole. Each limiting pin is connected to the cone head, and there is a gap between the pin head and the bottom end of the countersunk hole.

[0013] In the preferred embodiment, the telescopic rod assembly has a hollow structure, with the lower end of the lead screw connected to the hull and the upper end of the lead screw equipped with a sliding brace, the outer wall of which is slidably connected to the inner wall of the telescopic rod assembly.

[0016] The beneficial effects of this invention are as follows: The use of retractable and foldable extension plates reduces lateral wind resistance and prevents excessive force from lateral crosswinds on the canopy, thus affecting its normal raising; the spring-isolated drive system and telescopic rod assembly reduce the instantaneous impact of hull undulations on the drive device, extending hardware lifespan; the transfer case drives multiple lifting rod assemblies to operate in unison, preventing a single telescopic rod assembly from jamming and bending the canopy and rod assembly due to driving force; the fan-shaped rods, fan-shaped slides, and springs form multiple driving lifting circuits, ensuring the continuous raising and lowering of the canopy device even if a single fan-shaped rod is jammed, thus enhancing the visitor experience.

Detailed Implementation

[0032] like Figure 1-13 A cruise ship roof lifting system includes a roof device, lifting rod assemblies, and a roof drive system. At least four lifting rod assemblies are connected to the lower end of the roof device. The roof drive system is located in the bottom cabin of the ship and is used to drive the lifting rod assemblies to lift and lower. The lifting rod assembly includes a guide sleeve 201 connected to the bottom cabin of the ship. A telescopic rod group 2 that can be lifted and lowered is provided in the guide sleeve 201. The upper end of the telescopic rod group 2 is connected to the roof device.

[0033] In a preferred embodiment, the canopy device includes a canopy 1 and a frame 102. The frame 102 supports the canopy 1. Each of the four sides of the canopy 1 is provided with a rotatable extension side plate 101. One end of each extension side plate 101 is provided with an extension plate shaft 103. Each extension plate shaft 103 is provided with a first bevel gear 104 at its end. Adjacent extension plate shafts 103 are arranged vertically and are sequentially meshed and driven by the first bevel gears 104. An extension plate driving device is also provided to drive the extension plate shafts 103 to rotate.

[0034] The frame 102 is a rectangular plate or rectangular frame structure, with at least four corners equipped with raised connecting blocks 107, the upper ends of which support the canopy 1. The frame 102 is also equipped with a support base, which contains a bearing and is rotatably connected to the extension plate pivot 103.

[0035] Each extension plate shaft 103 is arranged in a rectangular structure, wherein the three corners of the rectangle are engaged by the paired first bevel gears 104, and the last corner is not engaged. The installed bevel gears are used to engage with the bevel gears at the shaft end of the extension plate drive device, namely the extension plate drive motor 105. The extension plate drive motor 105 is connected to the frame 102 through a bracket, and the extension plate drive motor 105 is a geared motor.

[0036] The extension panel 101 has an adjustable flip angle, allowing it to unfold outwards to provide shade, and the angle is adjustable. It can also be flipped inwards and retracted to reduce wind resistance.

[0037] In the preferred embodiment, one end of the canopy 1 is fitted to the outer wall of the extension plate pivot 103, and a sealing strip 106 is provided inside the end of the canopy 1 at the fitting point.

[0038] The sealing strip 106 is made of rubber or silicone to prevent rainwater from seeping into and dripping from the ceiling.

[0039] In a preferred embodiment, the lifting rod assembly further includes a lead screw 202 and a nut 204 sleeved on the lead screw 202. The ceiling drive system drives the lead screw 202 to rotate. A sleeve 205 is also provided, which is slidably connected to the guide sleeve 201. The nut 204 is connected to the sleeve 205. The sleeve 205 is slidably sleeved with the telescopic rod assembly 2. A first buffer spring 210 is provided between the sleeve 205 and the telescopic rod assembly 2.

[0040] The outer wall of the sleeve 205 is provided with a guide strip-shaped protrusion, which slides in the groove on the inner wall of the guide sleeve 201. The sleeve 205 can only slide and cannot rotate.

[0041] The first buffer spring 210 can isolate the roof drive system and the telescopic rod assembly 2. When the lead screw 202 rotates, the lead nut 204 rises along the guide sleeve 201 and lifts the sleeve 205. The sleeve 205 squeezes the first buffer spring 210. The upper end of the first buffer spring 210 squeezes the telescopic rod assembly 2 and forces the telescopic rod assembly 2 to rise. When the cruise ship rises and falls with the waves, the sudden increase or decrease in force between the hull and the roof is buffered by the first buffer spring 210, effectively improving the damage to the roof drive system caused by the sudden change in vertical acceleration.

[0042] When the roof structure is subjected to lateral wind force, the traditional guide rods or lifting rods rub against the guide sleeves, causing one or more of them to experience increased frictional resistance. Even if the guide sleeve 201 contains ball bearings, if the lifting rods adopt an independently driven structure, the lifting rods with increased frictional resistance will move slowly, while the smoothly driven lifting rods will move quickly. Since the roof of a cruise ship is generally equipped with lifting rods at the four corners, the span is large and the lever arm is long, making it easy to bend the lifting rods or the roof frame, causing jamming and making subsequent repairs difficult. The first buffer spring 210 can store driving force for a short time, but when the spring is fully compressed, the drive system will still directly act on some lifting rods, causing a situation similar to off-center loading and bending the structural components.

[0043] Therefore, in the preferred embodiment, each lead screw 202 is provided with a second bevel gear 203 at its lower end. The roof drive system includes a transfer case 4, which is provided with an input shaft and a first output shaft and a second output shaft that rotate in the same direction. It is also provided with at least two transverse drive shafts 405. The first output shaft and the second output shaft are connected to each transverse drive shaft 405 by belt drive or chain drive. Each transverse drive shaft 405 is provided with a third bevel gear 406 at both ends, and each third bevel gear 406 meshes with each second bevel gear 203.

[0044] It also includes a roof lifting drive motor 407 with a reducer, which is connected to the input shaft. The transfer case 4 contains a first transmission wheel 401, which is sleeved on the input shaft. On both sides of the first transmission wheel 401, there are a second transmission wheel 402 and a third transmission wheel 403 that drive the first transmission wheel 401. The second transmission wheel 402 is sleeved on the first output shaft, and the third transmission wheel 403 is sleeved on the second output shaft. The first transmission wheel 401, the second transmission wheel 402, and the third transmission wheel 403 are gears or friction wheels. The second synchronous belt device 404 is a synchronous belt, a friction belt, or a wheel and sprocket device. When it is a synchronous belt device, the output shaft end and the middle of the transverse transmission shaft 405 are sleeved with synchronous pulleys.

[0045] Because a single drive system simultaneously drives all four lifting rod assemblies, once one lifting rod assembly is engaged and the first buffer spring 210 is compressed to its limit, the transverse drive shaft 405 and the transfer case 4 are also engaged. There is no additional pushing force on the other lifting rods besides the spring holding force, thus the four lifting rods are in balance. When short-term gusts of wind arrive, the first buffer spring 210 can buffer and store some of the upward driving force, causing the canopy device to rise intermittently. When long gusts of wind arrive, the drive system engages, and all four lifting rods remain stationary, preventing the structure from being bent.

[0046] The roof lifting drive motor 407 can be a servo motor with a set maximum torque, or a torque sensor can be installed. When the telescopic rod assembly 2 jams and the motor exceeds the maximum set torque, the drive can be stopped to prevent further torque output to the telescopic rod assembly 2. Alternatively, it can first reverse to lower the specified height, and then continue to rotate forward until it rises to the target height; that is, the device itself reverses to repair or reduce jamming. If repeated self-adjustment still results in jamming, for example, if it reverses three times, each time with a slightly larger reverse adjustment (similar to climbing a slope), then manual fault handling is prompted.

[0047] The intermittent raising and lowering effect described above can meet the daily needs of ordinary cruise ships, but for some high-end yachts, if gusts of wind cause the roof to raise and lower intermittently or stop raising and lowering, it will undoubtedly greatly reduce the experience of tourists.

[0048] Therefore, in the preferred embodiment, the telescopic rod assembly 2 includes at least three fan-shaped rod pieces 207, the ends of which are connected sequentially to form a cylindrical structure. The sleeve 205 also has at least three fan-shaped sliding pieces 206, the ends of which are connected sequentially to form a cylindrical structure. The sleeve 205 and the fan-shaped sliding pieces 206 are slidably connected. One end of each fan-shaped sliding piece 206 is connected to each fan-shaped rod piece 207. There are multiple first buffer springs 210, with both ends of the first buffer springs 210 abutting against the sleeve 205 and each fan-shaped sliding piece 206 respectively. The upper end of the fan-shaped rod piece 207 is provided with a cone head 211 and a top connecting sleeve 208. The top connecting sleeve 208 is connected to the frame 102. The top connecting sleeve 208 has multiple cone holes 212, and each cone head 211 is sleeved with each cone hole 212. The end of the top connecting sleeve 208 near the frame 102 is provided with a countersunk hole 214.

[0049] When the roof is raised or lowered, it is best to flip and retract the extension side plate 101 to reduce lateral wind resistance. When lateral gusts occur, the lateral force is transmitted to the telescopic rod assembly 2 through the roof device. The friction between the telescopic rod assembly 2 and the guide sleeve 201 increases. Since the telescopic rod assembly 2 consists of three independently rising and falling fan-shaped rods 207, even if the contact position of two fan-shaped rods 207 with the guide sleeve 201 is too tight, that is, the friction between two fan-shaped rods 207 and the inner wall of the guide sleeve 201 increases at the same time, it can still be ensured that at least one fan-shaped rod 207 is in a smooth state. At this time, the sleeve 205 continues to rise under the drive of the roof drive system. Since the fan-shaped sliding plate 206 is connected to the sleeve 205 through the first buffer spring 210, two of the fan-shaped sliding plates 206 are fixed and the first buffer spring 210 is compressed, while the other fan-shaped sliding plate 206 is pushed by the first buffer spring 210 to continue to rise. The cone 211 at the upper end of the sector-shaped rod 207 pushes against the cone hole 212, causing the top connecting sleeve 208 to rise. Since the top connecting sleeve 208 and the sector-shaped rod 207 are connected by a conical surface, the other two cone holes 212 can easily disengage from the other two cones 211. At the moment of disengagement, the force of the canopy device on the originally clamped sector-shaped rod 207 disappears, and the force on the originally smooth sector-shaped rod 207 suddenly increases, which may cause this sector-shaped rod 207 to also become clamped. However, since the other two sector-shaped rods 207 are in a smooth state, under the action of the first buffer spring 210 in a compressed state and the continuous driving force of the drive system, these two sector-shaped rods 207 are pushed up by the cone 211 again, causing the canopy device to continue to rise, and another cone 211 disengages from the cone hole 212. This cycle alternates to ensure the continuous rise of the canopy device.

[0050] In a preferred embodiment, a limiting pin 213 is also provided. Multiple limiting pins 213 are provided in the countersunk hole 214. Each limiting pin 213 is connected to the cone head 211. The pin head of the limiting pin 213 has a gap with the bottom end of the countersunk hole 214.

[0051] The upper end of the limiting pin 213 is provided with a large end. When the cone 211 is disengaged from the cone hole 212 by a certain height, it is limited by the large end. The depth of the large end from the bottom of the countersunk hole 214 is less than the length of the cone 211, so that the top connecting sleeve 208 will not completely detach from the cone 211, preventing the entire roof 1 from being blown away by the wind.

[0052] In the preferred embodiment, the telescopic rod assembly 2 has a hollow structure, the lower end of the lead screw 202 is connected to the hull, and the upper end of the lead screw 202 is provided with a sliding support 209, the outer wall of the sliding support 209 is slidably connected to the inner wall of the telescopic rod assembly 2.

[0053] Since the upper end of the lead screw 202 is a cantilever structure, the sliding support 209 uses copper ceramic or Teflon-coated outer wall to reduce the coefficient of friction and slides with the inner hole of the telescopic rod assembly 2 to form effective support.

[0054] In a preferred embodiment, the outer wall of the sleeve 205 is provided with a first strip-shaped protrusion 215, the inner wall of the guide sleeve 201 is provided with a first strip-shaped groove, the first strip-shaped groove is slidably engaged with the first strip-shaped protrusion 215, the outer wall of the fan-shaped slide 206 is provided with a second strip-shaped protrusion 216, the inner wall of the sleeve 205 is provided with a second strip-shaped groove, the second strip-shaped protrusion 216 is slidably engaged with the second strip-shaped groove.

[0055] The combination of the strip groove and the strip protrusion can ensure sliding while preventing circumferential rotation.

[0056] In a preferred embodiment, the lower end of the frame 102 is provided with a support connection device 3. The support connection device 3 includes a connection seat 301. One side of the connection seat 301 is provided with a connection flange sleeve 303 that connects to the telescopic rod assembly 2. The other side of the connection seat 301 is provided with a universal connection seat 302 with a ball joint 304. The universal connection seat 302 is connected to the frame 102. A ball joint connecting block 305 is also provided. One end of the ball joint connecting block 305 is connected to the ball joint 304. A partition is provided in the middle of the connection seat 301. A second buffer spring 306 and a third buffer spring 308 are respectively provided on both sides of the partition of the connection seat 301. The two ends of the second buffer spring 306 abut against the partition of the connection seat 301 and the ball joint 304, respectively. A connecting screw 307 is also provided. The connecting screw 307 passes through the partition of the connection seat 301 to connect to the ball joint 304. The two ends of the third buffer spring 308 abut against the connecting screw 307 and the partition of the connection seat 301, respectively.

[0057] Since the canopy 1 is generally made of fiberglass or thin-walled steel plate, it has a large area, thin thickness, and is prone to deformation. Therefore, the installation positions at the four corners are often not uniform in height and have a certain degree of deformation. By connecting the frame 102 with the telescopic rod assembly 2 through the support connection device 3, it can adapt to this deformation and installation height difference, and reduce the difficulty of installation and debugging of multiple lifting rod assemblies connected to the frame 102.

[0058] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
