Description

Technical Field

[0001] This utility model relates to the field of amusement equipment technology, and in particular to a pirate ship drive device. Background Technology

[0002] As a core attraction of large-scale amusement rides, the stability and safety of the pirate ship's drive system are paramount. Traditional pirate ship drive systems primarily employ a hydraulic cylinder structure that directly lifts the friction wheel, transmitting power through the contact between the friction wheel and the ship's hull. However, the vertical stroke of the friction wheel is limited by the hydraulic cylinder's stroke, allowing only a limited range of positional adjustment. This results in insufficient contact time between the friction wheel and the hull, leading to low kinetic energy transfer efficiency during acceleration and a longer acceleration time, thus limiting the thrill for riders. Furthermore, traditional pirate ship drive systems often use rigid connections, resulting in significant noise and vibration during transmission. This not only reduces rider comfort but also increases the risk of fatigue damage to the transmission components. Utility Model Content

A lifting mechanism is provided on the sliding table to drive the swing frame to swing upward around the bearing seats so that the wheel surface of the friction wheel abuts against the bottom surface of the pirate ship.

A lower support rod is passed through the two hinged seats. Two lower connecting rods are rotatably sleeved on the outer circumference of the lower support rod. The other end of each lower connecting rod is rotatably connected to an upper connecting rod. The other ends of the two upper connecting rods are rotatably connected to the floating block.

Detailed Implementation

[0025] The specific technical solutions of this utility model are further described below to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0027] Please refer to Figures 1-4 A pirate ship drive device includes a base 1, a transmission box 2 fixedly welded to one side of the upper part of the base 1, a limit plate 3 fixedly welded to the base 1 on one side of the transmission box 2, a horizontal linear slide rail 4 fixedly welded to the base 1 between the limit plate 3 and the transmission box 2, the linear slide rail 4 is a precision guide rail structure with several guide grooves 7 inside, and a sliding table 5 connected to the power output end of the linear drive mechanism is set inside the linear slide rail 4, the main drive unit that drives the pirate ship to swing back and forth is mounted on the sliding table 5; during installation, the extension direction of the linear slide rail 4 should be coplanar with the swing direction of the pirate ship's hull.

[0028] The main drive unit includes a swing frame 6 mounted above the sliding table 5, a power device fixedly mounted on the swing frame 6, and a friction wheel 8 rotatably mounted on the swing frame 6 and connected to the power device for transmission. Two symmetrically distributed bearing seats 9 are fixedly mounted on the front side of the upper surface of the sliding table 5. One end of the swing frame 6 is rotatably connected to the bearing seat 9 through an integrally connected connecting shaft. A lifting mechanism is provided on the sliding table 5 to drive the swing frame 6 to swing upward around the bearing seat 9 so that the wheel surface of the friction wheel 8 abuts against the bottom surface of the pirate ship.

[0029] In the above structure, in order to achieve the buffering and shock absorption effect, a buffer groove 10 is provided on the lower surface of the other end of the swing frame 6. A floating block 11 is provided in the buffer groove 10. Multiple energy-absorbing springs 12 are provided between the floating block 11 and the bottom of the buffer groove 10. The power output end of the lifting mechanism is connected to the swing frame 6 through the floating block 11. The floating block 11 and the buffer groove 10 are in sliding fit.

[0030] In the above structure, to increase the maximum swing angle of the swing frame 6 while ensuring a compact overall structure, the lifting mechanism includes two hinged seats 13 fixedly mounted on the upper surface of the sliding table 5 and symmetrically distributed on the left and right. A lower support rod 14 passes through both hinged seats 13. Two lower connecting rods 15 are rotatably sleeved on the outer circumference of the lower support rod 14. Each lower connecting rod 15 has an upper connecting rod 16 rotatably connected to its other end. The other ends of the two upper connecting rods 16 are rotatably connected to the floating block 11. An upper support rod 17 is fixedly connected to a section of the two upper connecting rods 16 away from the floating block 11. The upper support rod 17 is parallel to the lower support rod 14 and is connected via a telescopic component. The lower connecting rods 15 and upper connecting rods 16 form a two-stage lever mechanism. When the telescopic component pushes the upper support rod 17, the linear displacement is converted into an amplified angular displacement through the linkage ratio. Compared to the traditional structure (i.e., directly connecting the hinged seats 13 and the swing frame 6 via a telescopic component), this effectively increases the swing stroke, maximizes the contact transmission time between the friction wheel 8 and the hull, and ensures a compact overall structure.

[0031] Specifically, the telescopic component comprises two symmetrically arranged lifting cylinders 18. The cylinder barrel of the lifting cylinder 18 is rotatably connected to the lower support rod 14, and the piston rod of the lifting cylinder 18 is rotatably connected to the upper support rod 17. The telescopic component can also be a common component structure in the art, such as an electro-hydraulic actuator or a hydraulic cylinder.

[0032] To ensure transmission accuracy and response speed, the linear drive mechanism is specifically a lead screw and nut mechanism, wherein the lead screw 19 of the lead screw and nut mechanism is parallel and rotatably mounted in the linear slide rail 4 through a bearing, and the nut of the lead screw and nut mechanism is fixedly connected to the sliding table 5 as a whole; the two ends of the lead screw 19 are respectively rotatably mounted inside the transmission box 2 and the limiting plate 3.

[0033] One end of the aforementioned lead screw 19 extends into the transmission box 2 and is fixedly fitted with a driven bevel gear 20. A shift motor 21 is vertically arranged on the top of the transmission box 2. The power output end of the shift motor 21 passes downward through the top wall of the transmission box 2 and is fixedly fitted with a driving bevel gear 22 that is in transmission connection with the driven bevel gear 20.

[0034] The base 1 is welded from high-strength steel. The side of the base 1 is integrally connected with several connecting ears 23 for easy installation and fixing. Each connecting ear 23 is provided with a mounting hole 24 for bolts to pass through.

[0035] The power unit is a drive motor 25 fixedly installed on the swing frame 6. The power output end of the drive motor 25 is fixedly fitted with a drive pulley 26, and a driven pulley 27 is fixedly fitted on the axle of the friction wheel 8. The drive pulley 26 and the driven pulley 27 are connected and transmitted through a synchronous belt 28.

[0036] The outer circumferential surface of the friction wheel 8 is provided with rubber anti-slip treads to further improve the friction transmission efficiency.

[0037] In use, this utility model first securely mounts the entire drive unit onto a preset foundation via the mounting holes 24 on the connecting ears 23 of the base 1, ensuring that the extension direction of the linear slide 4 remains parallel to the swing trajectory of the pirate ship. Before startup, the shift motor 21 drives the lead screw 19 to rotate via a bevel gear pair, causing the sliding table 5 to move along the linear slide 4 to the initial position. Figure 1 Simultaneously, the lifting cylinder 18 actuates, pushing the swing frame 6 to rotate around the bearing seat 9 via the linkage mechanism, causing the friction wheel 8 to contact the bottom surface of the hull with appropriate pressure. When the drive motor 25 starts, it drives the friction wheel 8 to rotate via the synchronous belt 28, thereby driving the pirate ship to begin swinging.

[0038] During operation, the shift motor 21 intelligently adjusts the position of the sliding table 5 according to a preset program, causing the sliding table 5 to move synchronously with the hull's swing direction. Simultaneously, the lifting cylinder 18 remains extended, ensuring continuous contact between the friction wheel 8 and the hull. When the hull swings to its limit position, the sliding table 5 automatically returns to its initial position, and the lifting cylinder 18 retracts synchronously to avoid interference with the hull. This process is repeated in the next swing cycle. Throughout the entire operation, the energy-absorbing spring 12 effectively absorbs impact energy through the sliding displacement of the floating block 11, significantly reducing the vibration amplitude of the transmission system and ensuring the smooth operation of this drive device.

[0039] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
