Description

Technical Field

[0001] This application relates to the field of amusement equipment technology, and more particularly to a pneumatic catapult. Background Technology

[0002] Nowadays, many large amusement parks use launch start mode for roller coasters and other rides to provide users with a novel and exciting experience. This mode accelerates the stationary vehicle to a very high speed in a very short time, creating a strong sense of acceleration.

[0003] Currently, the launch start method for roller coasters often uses a free-fall mode to obtain a large initial velocity. This involves setting up a steeply inclined lift section at the initial position of the roller coaster track. The train is first lifted onto the lift section by a chain, and then released freely. The train begins to fall entirely under gravity and travels into the horizontal section with a very high initial velocity, thus achieving the launch start of the roller coaster. However, this method of obtaining a large initial velocity by relying on gravitational potential energy requires a straight lift section at the initial position of the track, resulting in a large overall track area and high construction costs. Summary of the Invention

[0004] In view of this, this application proposes a pneumatic catapult.

[0005] According to one aspect of this application, a pneumatic catapult is provided, which is suitable for being installed inside the roller coaster track and located at the starting position of the roller coaster, including: a fixed pulley device, a tensioning pulley device, a traction rope, a catapult cylinder and a launch plate; The tensioning pulley device includes two or more first pulleys, and the fixing pulley device includes two or more second pulleys; The number of traction ropes, the number of first pulleys, and the number of second pulleys are all the same. Each traction rope is wrapped around a first pulley and a second pulley, and each traction rope passes through the cavity of the cylinder of the ejection cylinder. Each traction rope is connected at both ends to the two ends of the launch plate. The launch plate is equipped with a catapult hook assembly at the top, which is suitable for hooking the push rod at the bottom of the roller coaster; The ejection cylinder includes a cylinder barrel and a piston assembly located inside the cylinder barrel, the piston assembly being movable along the length of the cylinder barrel, and the piston assembly being connected to the traction rope; one end of the cylinder barrel has an air inlet for inputting high-pressure gas, and the other end of the cylinder barrel has an air outlet for discharging gas, so that when high-pressure gas is input into the cylinder barrel through the air inlet, the piston assembly moves rapidly inside the cylinder barrel under the pressure of the high-pressure gas, thereby driving the traction rope and the launch plate to move.

[0006] In one possible implementation, the tensioning pulley device further includes: a first mounting frame, on which a first pin is provided, and two or more first pulleys are rotatably mounted on the first pin.

[0007] In one possible implementation, the tensioning pulley device further includes: a tensioning assembly; the tensioning assembly is connected to a first pin and is suitable for tensioning each traction rope by means of two or more first pulleys.

[0008] The tensioning assembly includes: a tensioner and a U-shaped seat; One end of the tensioner is connected to the U-shaped seat, and the two ends of the opening of the U-shaped seat are respectively connected to the two ends of the first pin.

[0009] In one possible implementation, the fixed pulley device further includes: a second mounting bracket, on which a second pin is provided, and two or more second pulleys are rotatably mounted on the second pin.

[0010] In one possible implementation, the fixed pulley device further includes: two or more drive devices, each drive device being connected to each second pulley via a transmission, suitable for driving the second pulley to rotate in order to move the traction rope.

[0011] In one possible implementation, the cylinder barrel includes two or more cylinder pipe sections connected in sequence, with the air inlet and air outlet respectively located on the cylinder pipe sections at two ends.

[0012] In one possible implementation, both ends of two or more traction ropes are connected to the launch plate via rope connectors.

[0013] In one possible implementation, the rope connector includes: a connector, a connecting rod, and tensioners equal in number to the traction ropes; one end of each traction rope is connected to one end of each tensioner, and the other end of each tensioner is connected to the connector, the connector being connected to the launch plate via the connecting rod.

[0014] In one possible implementation, the launch hook assembly includes: a support crank and a lever hook; one end of the support crank is movably connected to the launch plate via a first elastic part, the other end of the support crank is hinged to the lever hook, one end of the lever hook is provided with a hook portion for contacting a push rod at the bottom of the roller coaster, and the other end of the lever hook is hinged to the launch plate.

[0015] Beneficial effects: The first pulley of the tensioning pulley device and the second pulley of the fixing pulley device are suitable for providing support for the traction rope and enabling the traction rope to be turned. The tensioning pulley device is suitable for tightening the traction rope, adjusting its tension to ensure it is securely wound around the first and second pulleys, preventing slippage due to loosening. The two ends of the traction rope are connected to the launching plate, thus forming a closed-loop structure with the launching plate. When the traction rope moves on the first and second pulleys, it can simultaneously drive the launching plate to move. The cylinder is suitable for providing a pressure space for high-pressure gas, which enters from the air inlet. The high-pressure gas in the cylinder impacts the piston assembly, causing it to move rapidly within the cylinder. This piston assembly drives the traction rope at high speed, which in turn drives the launch plate at high speed. The launch hook assembly at the top of the launch plate hooks onto the push rod at the bottom of the roller coaster. The launch plate moves the roller coaster and provides it with a large initial velocity. When the piston stops moving at the other end of the cylinder, the traction rope stops moving, and the launch plate stops simultaneously. The roller coaster continues to move forward due to inertia, thus achieving the launch launch. In summary, this application utilizes a pneumatic launch method to achieve high-speed starts for the roller coaster, providing a powerful acceleration experience. It eliminates the need for a diving lift section at the initial track position, simplifying the track structure and reducing construction costs. The overall equipment boasts high operational reliability, low maintenance costs, and ease of subsequent repair and maintenance.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0025] Figure 1 This diagram shows the main structure of the pneumatic catapult according to an embodiment of this application; Figure 2 This invention provides a schematic diagram of the structure of a pneumatic catapult according to an embodiment of the present application. Figure 3 A partial structural diagram of the pneumatic catapult according to an embodiment of this application is shown; as follows: Figure 1 As shown, this pneumatic catapult includes: a fixed pulley device 100, a tensioning pulley device 200, a traction rope 300, a catapult cylinder, and a launch plate 500; the tensioning pulley device 200 includes two or more first pulleys 210, and the fixed pulley device 100 includes two or more second pulleys 110; the number of traction ropes 300, the number of first pulleys 210, and the number of second pulleys 110 are all the same, each traction rope 300 is wound around one first pulley 210 and one second pulley 110, and each traction rope 300 passes through the cavity of the cylinder 400; the two ends of each traction rope 300 are respectively connected to the two ends of the launch plate 500; the top of the launch plate 500 is provided with a catapult hook. The components include a catapult hook assembly suitable for hooking the push rod 910 at the bottom of the roller coaster 900; the catapult cylinder includes a cylinder 400 and a piston assembly 600, the piston assembly 600 is located inside the cavity of the cylinder 400 and can move along the length of the cylinder 400, and the piston assembly 600 is connected to the traction rope 300; one end of the cylinder 400 is provided with an air inlet 410 for inputting high-pressure gas, and the other end of the cylinder 400 is provided with an air outlet 420 for discharging gas, so that when high-pressure gas is input into the cylinder 400 through the air inlet 410, the piston assembly 600 moves inside the cylinder 400 under the pressure of the high-pressure gas and drives the traction rope 300 and the launch plate 500 to move.

[0026] It should be noted that this application is applicable to the starting position of roller coaster 900 on roller coaster track, located between two rails, so that the catapult hook assembly at the top of the launch plate 500 can contact the push rod 910 at the bottom of roller coaster 900. The tensioning pulley device 200's first pulley 210 and the fixing pulley device 100's second pulley 110 are used to provide support for the traction rope 300 and to enable the traction rope 300 to turn. The tensioning pulley device 200 is used to tighten the traction rope 300, adjust its tension to make it securely wrapped around the first pulley 210 and the second pulley 110, and prevent slippage due to loosening. The two ends of the traction rope 300 are connected to the launch plate 500, so the traction rope 300 and the launch plate 500 form a closed loop structure. When the traction rope 300 moves on the first pulley 210 and the second pulley 110, it can simultaneously drive the launch plate 500 to move. The cylinder 400 is used to provide a pressure space for high-pressure gas. In the initial state, the piston assembly 600 is located at the air inlet 410 of the cylinder 400. The high-pressure gas entering the cylinder 400 from the air inlet 410 can impact the piston assembly 600 and drive the piston. The piston assembly 600 moves rapidly within the cylinder 400. Since the piston assembly 600 is connected to the traction rope 300, and the traction rope 300 passes through the cylinder 400, the piston assembly 600 can drive the traction rope 300 to move at high speed during its high-speed movement. The traction rope 300, in turn, drives the launch plate 500 to move at high speed. The launch hook assembly at the top of the launch plate 500 is designed to engage with the push rod 910 at the bottom of the roller coaster 900 (amusement ride). The launch plate 500 can drive the roller coaster to move and provide it with a large initial velocity. When the piston assembly 600 stops at the other end of the cylinder 400, the traction rope 300 stops moving, and the launch plate 500 stops simultaneously. The roller coaster 900 continues to move forward due to inertia. The fixed pulley device 100 can reset the launch plate 500 via the traction rope 300, ready for the next launch of the roller coaster 900.

[0027] In summary, this application utilizes a pneumatic catapult system to achieve a high-speed start for the roller coaster 900, providing passengers with an extremely intense and thrilling acceleration experience. The elimination of the need for steep drops or mechanical lifting devices in the initial track section simplifies the overall track structure, and the significantly more compact track layout greatly reduces design and construction costs. Furthermore, based on the inherent characteristics of the pneumatic drive system, this process boasts high energy conversion efficiency and controllable acceleration, effectively ensuring high reliability and safety during the initial launch phase. The overall equipment operation is more stable and reliable, with lower construction and long-term maintenance costs, and it facilitates fault diagnosis and subsequent maintenance.

[0028] In one possible implementation, such as Figure 2As shown, the tensioning pulley device 200 further includes: a first mounting bracket 220, on which a first pin 240 is provided, and two or more first pulleys 210 are rotatably mounted on the first pin 240. The first pin 240 is suitable for providing a mounting base for the first pulleys 210.

[0029] Furthermore, such as Figure 8 and Figure 9 As shown, the first mounting bracket 220 includes: a first base 223, four first support rods 221, two guide posts 224, and two support platforms 225. The main body of the first base 223 is a rectangular frame structure, suitable for installation on the ground. The four first support rods 221 are respectively vertically arranged at the four corners of the top surface of the first base 223, and a reinforcing rod 222 is provided between each first support rod 221 and the first base 223. Each guide post 224 is arranged on the top of two adjacent first support rods 221 and the two guide posts 224 are arranged parallel to each other. The two support platforms 225 are respectively installed on the two guide posts 224 and are located between the two guide posts 224. Each support platform 225 is provided with a first mounting block 226. A through hole is opened in the middle of the first mounting block 226 for the first pin 240 to pass through. The two ends of the first pin 240 pass through the through holes of the first mounting blocks 226 on the two support platforms 225 to realize the installation of the first pin 240.

[0030] Furthermore, such as Figure 11 As shown, round nuts 246 are fixedly provided at both ends of the first pin 240 to limit the first pin 240 and prevent the first pin 240 from falling off from the first mounting block 226.

[0031] In one possible implementation, such as Figure 10 As shown, the support platform 225 is composed of multiple plate-shaped structures. Two supports 228 are provided on one side of the support platform 225 that connects to the guide column 224. Each support 228 is a rectangular block structure. Each support 228 has a through hole for the guide column 224 to pass through. Four cover plates 229 suitable for connecting the support 228 are fixed on the guide column 224. Each support 228 is connected to the two cover plates 229 that are tightly attached to each other by four bolts 2291, thereby firmly installing the two support platforms 225 on the two guide columns 224.

[0032] Furthermore, such as Figure 10 As shown, the first mounting block 226 on the support platform 225 is mounted on the support platform 225 by two or more first bolts 227.

[0033] Two or more first pulleys 210 are arranged in parallel between two support platforms 225. Each of the two or more first pulleys 210 is fitted with a first pin 240 and is coaxially arranged with the first pin 240. Further, such as... Figure 10 and Figure 11 As shown, each first pulley 210 has a first coupling 241 on both sides. The two first couplings 241 are connected to one first pulley 210 by two or more second bolts 244. The two first couplings 241 are used to firmly clamp the middle first pulley 210. Each of the two first couplings 241 has a limiting ring 243 on the side away from the middle first pulley 210. The limiting ring 243 is fixedly connected to the first pin 240. Under the action of the two limiting rings 243, the two middle first couplings 241 and the first pulley 210 are limited to avoid the first pulley 210 from displacing along the length direction of the first pin 240.

[0034] In one possible implementation, such as Figure 11 As shown, each first coupling 241 and the first pin 240 is provided with a bearing 242 to ensure the rotational accuracy of the first pulley 210 and reduce friction.

[0035] Furthermore, such as Figure 8 As shown, the tensioning pulley device 200 has two first pulleys 210. The two first pulleys 210 are arranged sequentially along the length of the first pin 240. The two first pulleys 210 are connected to the first pin 240 in the same way. Each first pulley 210 is wound with a traction rope 300.

[0036] In one possible implementation, the tensioning pulley device 200 further includes: a tensioning assembly; the tensioning assembly is connected to the first pin 240 and is suitable for tensioning each traction rope 300 by two or more first pulleys 210; so that the traction rope 300 fits tightly against the first pulley 210 and the second pulley 110. Further, the tensioning assembly includes: a tensioner 230 and a U-shaped seat 231; one end of the tensioner 230 is connected to the U-shaped seat 231, and the two ends of the opening of the U-shaped seat 231 are respectively connected to both sides of the first mounting bracket 220; as shown... Figure 10 As shown, the clamping end of the tensioner 230 is connected to the closed side of the U-shaped seat 231 through the first connecting shaft 232, and the two open ends of the U-shaped seat 231 are respectively connected to the two support platforms 225 of the first mounting bracket 220 through two or more third bolts 234.

[0037] Furthermore, the tensioner 230 employs a hydraulic device, such as a hydraulic cylinder; preferably, pads 233 are provided on both the upper and lower sides of the opening of the U-shaped seat 231.

[0038] In one possible implementation, such as Figure 2As shown, the fixed pulley device 100 further includes: a second mounting bracket 120, on which a second pin 150 is provided, and two or more second pulleys 110 are rotatably mounted on the second pin 150. The second pin 150 is suitable for providing a rotating mounting base for the second pulleys 110.

[0039] Furthermore, such as Figure 4 As shown, the second mounting bracket 120 includes: a second base 121, four second support rods 122, and two support beams 130; the main body of the second base 121 has a rectangular frame structure, suitable for installation on the ground; the four second support rods 122 are respectively vertically arranged at the four corners of the top surface of the second base 121, and each support beam 130 is arranged on the top of two adjacent second support rods 122 and the two support beams 130 are arranged parallel to each other. A through hole 134 is opened in the middle of the support beam 130 for the second pin 150 to pass through. The two ends of the second pin 150 pass through the through hole 134 on the two support beams 130 to realize the installation of the second pin 150.

[0040] Furthermore, round nuts 154 are also fixed at both ends of the second pin 150, thereby limiting the second pin 150 to the second mounting bracket 120.

[0041] In one possible implementation, each support beam 130 has a first screw 132 at one end, one end of which is threadedly connected to a threaded sleeve 137, and the other end of the threaded sleeve 137 is connected to the support beam 130 via a second connecting shaft 136. Further, as... Figure 6 As shown, the end of the support beam 130 has a groove for the threaded sleeve 137 to pass through. One end of the threaded sleeve 137 is inserted into the groove and fitted with a second connecting shaft 136. One end of the first screw 132 is inserted into the threaded sleeve 137 and threadedly connected to the threaded sleeve 137. The other end of the first screw 132 is vertically provided with a handle 138, which is used to rotate the first screw 132 to adjust the length of the first screw 132 inserted into the threaded sleeve 137. The handle 138 can be engaged with other external structures. The second mounting bracket 120 is pulled by the first screw 132 to keep the traction rope 300 taut.

[0042] In one possible implementation, one end of each of the two support beams 130 is connected to a U-shaped plate 131, such as... Figure 5 and Figure 6 As shown, the two ends of the U-shaped plate 131 are respectively placed on the ends of the two support beams 130, and the inner side of the U-shaped plate 131 is adapted to make way for the two second pulleys 110; and the two ends of the U-shaped plate 131, the two support beams 130 and the two second support rods 122 are connected by a plurality of fourth bolts 133.

[0043] Two or more second pulleys 110 are arranged in parallel between two support beams 130. Each of the two or more second pulleys 110 is fitted with a second pin 150 and is coaxially arranged with the second pin 150. Further, such as... Figure 7 As shown, each second pulley 110 is provided with a second coupling 151 on both sides. The two second couplings 151 are connected to the second pulley 110 by two or more fifth bolts 152. The two second couplings 151 are used to firmly clamp the middle second pulley 110. Each of the two second couplings 151 is provided with a limiting ring on the side away from the second pulley 110. The limiting ring is fixedly connected to the second pin 150. Under the action of the two limiting rings, the two middle second couplings 151 and the second pulley 110 are limited to avoid the second pulley 110 from displacing along the length direction of the second pin 150.

[0044] Furthermore, there are two second pulleys 110. The structures of the first pulley 210 and the second pulley 110 are the same. The distance between the two first pulleys 210 is the same as the distance between the two second pulleys 110. Each first pulley 210 is opposite to each second pulley 110, so that the two traction ropes 300, which are individually wound on the two first pulleys 210 and the two second pulleys 110, can maintain a parallel relationship with each other.

[0045] In one possible implementation, such as Figure 7 As shown, each second coupling 151 and the second pin 150 is provided with a bearing 153 to ensure the rotational accuracy of the second pulley 110 and reduce friction.

[0046] In one possible implementation, such as Figure 5 As shown, the fixed pulley device 100 further includes two or more drive devices 140, each drive device 140 being connected to each second pulley 110 for driving the second pulley 110 to rotate and move the traction rope 300. It should be noted that after high-pressure gas is injected, the launch plate 500 moves rapidly from one end of the cylinder 400 to the other end of the cylinder 400 under the action of the piston assembly 600 and stops with the piston assembly 600. After the launch plate 500 stops moving, it needs to be moved back to its original position to prepare for the next launch operation. Therefore, the fixed pulley device 100 provides a drive device 140 for each second pulley 110 to drive the second pulley 110 to rotate synchronously.

[0047] Preferably, the drive device 140 is a geared motor.

[0048] Furthermore, it also includes a gear transmission assembly, with each drive unit 140 connected to each second pulley 110 via the gear transmission assembly; such as Figure 3As shown, the two drive units 140 are located on opposite sides of the two second pulleys 110. Further, as... Figure 5 and Figure 7 As shown, each gear transmission assembly includes: a drive shaft 181, a pinion 170 and a gear 160 meshing with each other; the output shaft of the drive unit 140 is connected to one end of the drive shaft 181 via a clutch, and the other end of the drive shaft 181 passes through the center hole of the pinion 170 and is keyed to the pinion 170; as shown Figure 7 As shown, the large gear 160 is sleeved on one of the second couplings 151 and fits against one side of the second pulley 110. The large gear 160, the two second couplings 151 and the second pulley 110 are fixedly connected by a plurality of fifth bolts 152. Thus, when the drive device 140 drives the small gear 170 to rotate, the small gear 170 synchronously drives the large gear 160 and the second pulley 110 to rotate. During the rotation of the second pulley 110, the traction rope 300 is moved.

[0049] Furthermore, the second mounting bracket 120 is equipped with drive unit support brackets on both sides, suitable for supporting and mounting two drive units 140 respectively, improving their positional stability and operational reliability. Further, such as Figure 7 As shown, the drive unit support frame includes: a first support member 124 and a support ramp 126; both sides of the first support member 124 are fixedly connected to two adjacent second support rods 122; one end of the support ramp 126 is connected to the second base 121, and the other end of the support ramp 126 is connected to the bottom of the first support member 124 to reinforce and support the first support member 124; the top surface of the first support member 124 is suitable for mounting the drive unit 140; the housing of the drive unit 140 is connected to the first support member 124 by four sixth bolts 125. Preferably, both the first support member 124 and the support ramp 126 are made of U-shaped steel.

[0050] In one possible implementation, a second support member 123 is provided above the drive unit support frame. The main body of the second support member 123 is plate-shaped, and its two sides are fixedly connected to two second support rods 122. The top surface of the second support member 123 is provided with two bearings 180 with vertical seats. The bearing seats of the two bearings 180 with vertical seats are fixedly connected to the second support member 123 by bolts. The drive shaft 181 passes through the inner ring of the two bearings 180 with vertical seats. The two bearings 180 with vertical seats are used to support the drive shaft 181 to make it stable, and to maintain the meshing connection between the pinion 170 and the gear 160.

[0051] In one possible implementation, the cylinder 400 includes two or more cylinder pipe sections 430 connected in sequence, with an inlet 410 and an outlet 420 respectively located on the cylinder pipe sections 430 at their two ends. Figure 12 As shown, the main body of the cylinder pipe section 430 is a circular tube structure with connecting flanges at both ends. Adjacent cylinder pipe sections 430 are connected by multiple seventh bolts 431. The multiple seventh bolts 431 pass through the flange connecting plates of the two adjacent cylinder pipe sections 430 and are arranged sequentially along the circumference of the flange connecting plates. The seventh bolts 431 are locked with nuts, thereby realizing the connection between the two cylinder pipe sections 430.

[0052] Preferably, an O-ring can be installed between two adjacent cylinder pipe sections 430 for sealing.

[0053] This application does not limit the specific number of cylinder pipe sections 430, and the specific number of cylinder pipe sections 430 can be determined according to the actual site conditions.

[0054] In one possible implementation, both cylinder pipe sections 430 at both ends are provided with end caps 470, and the end caps 470 cover the outer end faces of the cylinder pipe sections 430; such as Figure 14 As shown, the main body of the end cap 470 is a disc structure with multiple bolt holes at its edge. The end cap 470 covers the opening of the cylinder tube section 430 and is connected to the end face of the cylinder tube section 430 by multiple eighth bolts. The end cap 470 is designed to seal the cylinder barrel 400 so that the high-pressure gas moves in one direction inside the cylinder barrel 400.

[0055] Furthermore, such as Figure 18 As shown, the end caps 470 of the two cylinder pipe sections 430 at both ends are provided with the same number of rope passage holes 490 as the traction ropes 300. Each traction rope 300 enters and exits the cylinder 400 through the rope passage hole 490. A sealing seat 492 and a sealing nozzle 480 are provided at the rope passage hole 490 of the end cap 470. The sealing seat 492 is connected to the end cap 470 by bolts 491 and is coaxially arranged with the rope passage hole 490. One end of the sealing nozzle 480 passes into the central hole of the sealing seat 492 and is fixedly connected to the sealing seat 492 to cover the rope passage hole 490. A through hole is provided on the central axis of the sealing nozzle 480. The traction rope 300 passes through the through hole of the sealing nozzle 480 and can move within the through hole, thereby improving the sealing performance of the cylinder 400 while ensuring the smooth movement of the traction rope 300.

[0056] In one possible implementation, such as Figure 14As shown, a buffer device is provided in the middle of the inner side (the side facing each other) of the two end caps 470; it is suitable for providing buffer force for the piston assembly 600 to stop, avoiding damage to the piston assembly 600 caused by direct impact with the end cap 470, so as to improve the service life of the overall equipment. Furthermore, the buffer device includes: a buffer sleeve 471, a spring 472, and a buffer rod 473; one end of the buffer sleeve 471 is connected to the end cap 470 via a pad 477, and the three are fixed by bolts; one end of the buffer rod 473 passes through the inner hole of the buffer sleeve 471 and can move within the buffer sleeve 471 along its length; the other end of the buffer rod 473 is fitted with a first retaining ring, which is fixedly connected to the buffer rod 473; a second retaining ring is fitted on the outer wall of the buffer sleeve 471, which is fixedly connected to the buffer sleeve 471; the spring 472 is fitted on the buffer rod 473, with one end connected to the first retaining ring and the other end connected to the second retaining ring. When the piston assembly 600 impacts the buffer device, the piston assembly 600 presses down the buffer rod 473 and gradually compresses the spring 472, relying on the deformation of the spring 472 to absorb the impact energy, thus achieving a buffering effect.

[0057] Preferably, the length of the pad 477 on the end cap 470 near the air inlet 410 needs to be greater than the distance between the air inlet 410 and the end cap 470, so as to ensure that the high-pressure gas can push the piston assembly 600 towards the air outlet 420.

[0058] In one possible implementation, the buffer device further includes: a guide rod 474; one end of the guide rod 474 is fixedly connected to the first snap-fit ​​ring, the guide rod 474 passes through the limiting plate 476 on the outside of the second snap-fit ​​ring, and the other end of the guide rod 474 is provided with a limiting block 475. When the buffer rod 473 moves with the first snap-fit ​​ring, the guide rod 474 moves synchronously; when the buffer rod 473 is reset under the elastic force of the spring 472, the guide rod 474 also moves synchronously. The limiting plate 476 on the outside of the second snap-fit ​​ring is used to limit the limiting block 475 of the guide rod 474, which can prevent the buffer rod 473 from moving excessively and disengaging from the buffer sleeve 471.

[0059] In one possible implementation, there are two air inlets 410, which are arranged adjacently on the same cylinder manifold section 430; preferably, as shown in the example. Figure 4 As shown, the cylinder pipe section 430 where the air intake 410 is located is close to the fixed pulley device 100; as Figure 8 As shown, the cylinder pipe section 430 where the air outlet 420 is located is close to the tensioning pulley device 200. Both the air inlet 410 and the air outlet 420 have protruding flange connecting plates on their outer walls. The flange connecting plate of the air inlet 410 is suitable for connecting to an external air supply pipeline. The air compressor injects high-pressure gas into the air inlet 410 through the external air supply pipeline.

[0060] In one possible implementation, such as Figure 12 As shown, the cylinder barrel 400 is also provided with two pressure relief ports 440. The two pressure relief ports 440 are respectively provided on the two cylinder pipe sections 430 located in the middle. The pressure relief ports 440 are used to assist the exhaust port 420 in timely discharge of gas in the cylinder barrel 400, so as to ensure the smooth movement of the piston assembly 600 in the cylinder barrel 400 and avoid the gas pressure in the cylinder barrel 400 from hindering the movement of the piston assembly 600.

[0061] In one possible implementation, the cylinder barrel 400 is provided with two or more first fixing brackets; the two or more first fixing brackets are arranged evenly along the length of the cylinder barrel 400, such as... Figure 12 As shown, the first fixing frame includes: a base plate 451, a vertical plate 452, and two curved plates 450; the vertical plate 452 is vertically fixed to the top surface of the base plate 451, and the top of the vertical plate 452 is connected to the two curved plates 450, which are symmetrically arranged. The inner sides of the two curved plates 450 are suitable for simultaneously contacting and supporting the cylinder 400; reinforcing ribs 453 are also provided between the vertical plate 452, the curved plates 450, and the base plate 451 for reinforcement.

[0062] Preferably, a first fixing bracket is provided every two cylinder barrels 400.

[0063] In one possible implementation, the cylinder barrel 400 is provided with a second fixing bracket; the second fixing bracket is located at the connection of the two cylinder tube sections 430 located in the middle. For example... Figure 13 As shown, the second fixing frame includes: four fixing inclined plates 460; the four fixing inclined plates 460 are arranged in pairs opposite each other, each fixing inclined plate 460 has a base plate 463 at its bottom end, and each base plate 463 has a cross-shaped piece 462 at its bottom, which is suitable for insertion into the installation position, such as the ground. Each fixing inclined plate 460 has a vertical plate 464 at its other end. The vertical plate 464 is connected to the flange connecting plate of the cylinder pipe section 430 by a seventh bolt 431, and the vertical plates 464 of two opposite fixing inclined plates 460 are reinforcedly connected by bolts 461.

[0064] In one possible implementation, such as Figure 15 As shown, the piston assembly 600 includes: a piston disc 610, a balance ring 620, and two or more piston rods 630. The piston disc 610 is connected to the balance ring 620 through two or more piston rods 630, and the two or more piston rods 630 are arranged parallel to each other between the piston disc 610 and the balance ring 620.

[0065] In one possible implementation, such as Figure 17As shown, a supporting connecting rod structure is provided between the piston disc 610 and the balance ring 620. Two or more piston rods 630 are connected to the piston disc 610 and the balance ring 620 through the supporting connecting rod structure. Furthermore, the supporting connecting rod structure is composed of two or more inclined rods 640 connected end to end in sequence, and a "V" shape is formed between any two adjacent inclined rods 640. A connecting hole 641 suitable for inserting the piston rod 630 is opened at the connection point of any two adjacent inclined rods 640. One end of the piston rod 630 is inserted into the connecting hole 641, and the other end of the piston rod 630 is connected to the piston disc 610 or the balance ring 620 through a bolt 621.

[0066] Furthermore, the traction rope 300 is connected to the third connecting shafts on both sides of the piston disc 610 via hooks, such as... Figure 15 and Figure 16 As shown, each traction rope 300 is divided into two sections. One section is connected to the first hook 310, which is hooked onto the third connecting shaft on one side of the piston disc 610. The other section is connected to the second hook 320, which is hooked onto the third connecting shaft on the other side of the piston disc 610. The bearing seats 650 on both sides of the piston disc 610 are opposite each other to ensure that the traction ropes 300 on both sides of the piston disc 610 are in a straight line. The two bearing seats 650 on opposite sides of the piston disc 610 are connected to the piston disc 610 by two or more eighth bolts 612. The first hook 310 and the second hook 320 are hooked onto the third connecting shaft of the two bearing seats 650 on opposite sides of the piston disc 610, thereby firmly connecting the traction ropes 300 to the piston disc 610.

[0067] In one possible implementation, the piston assembly 600 further includes: contact blocks 611; contact blocks 611 are provided at the middle positions on both sides of the piston disc 610, and the contact blocks 611 on both sides are respectively opposite to the buffer devices of the two end caps 470, and are suitable for contacting the buffer rods 473 of the buffer devices.

[0068] In one possible implementation, the ends of the traction ropes 300 are all connected to the launch plate 500 via rope connectors. For example... Figure 19 As shown, the main body of the launch plate 500 is a rectangular plate structure. A fourth connecting shaft 540 is provided at each of the four corners of the launch plate 500, and the length direction of the fourth connecting shaft 540 is perpendicular to the plane of the launch plate 500. Each fourth connecting shaft 540 has a limiting wheel 541 fixed at both ends. The limiting wheel 521 is sleeved on the fourth connecting shaft 540 and is used to limit the movement of the connecting rod 340 in the middle. Figure 22As shown, the rope connector is suitable for connecting the ends of two traction ropes 300 into one piece and simultaneously connecting them to the launch plate 500. This ensures the stability of the launch plate 500 under force when the two traction ropes 300 move, and avoids the launch plate 500 from tilting due to asynchronous movement of the two traction ropes 300.

[0069] In one possible implementation, the rope connector includes: a connector 350, a connecting rod 340, and tensioners equal in number to the traction ropes 300; one end of each traction rope 300 is connected to one end of each tensioner, and the other end of each tensioner is connected to the connector 350; the connector 350 is connected to the launch plate 500 via the connecting rod 340. Figure 22 As shown, the connector 350 consists of two parallel triangular plates and three fifth connecting shafts 351; the three fifth connecting shafts 351 are vertically arranged between the two triangular plates and are located at the three corners of the triangular plates respectively; two tensioners are connected to two of the fifth connecting shafts 351 respectively; the main body of the connecting rod 340 is a "Y"-shaped rod structure, one end of the connecting rod 340 is sleeved on another fifth connecting shaft 351, the other end of the connecting rod 340 is sleeved on the fourth connecting shaft 540, and the launching plate 500 is embedded in the opening at one end of the connecting rod 340, thereby improving the uniformity of force on both sides of the launching plate 500.

[0070] Furthermore, the main body of the fifth connecting shaft 351 is cylindrical, with a through hole along its central axis for bolts to pass through. The fifth connecting shaft 351 passes through the top triangular plate and abuts against the bottom triangular plate. The bolt passes through the bottom triangular plate, the fifth connecting shaft 351 and the top triangular plate in sequence, and is locked with a nut to achieve a stable connection between the fifth connecting shaft 351 and the two triangular plates.

[0071] In one possible implementation, each tensioner includes: a second screw 352, a third screw 355, and a tensioning ring 354; the second screw 352 and the third screw 355 are respectively connected to both ends of the tensioning ring 354; as shown Figure 22 As shown, the tensioning ring 354 has through holes at both ends for the second screw 352 and the third screw 355 to pass through. Nuts 353 are fixed to both ends of the tensioning ring 354, and the nuts 353 are coaxial with the through holes. One end of the second screw 352 passes through the nut 353 and the through hole and is threadedly connected to the nut 353. One end of the third screw 355 passes through the nut 353 and the through hole on the other side. The other ends of the second screws 352 of the two tensioners are respectively sleeved on the two fifth connecting shafts 351; the other ends of the third screws 355 of the two tensioners are respectively sleeved on the connectors 330 at the ends of the two traction ropes 300.

[0072] In one possible implementation, such as Figure 20As shown, the catapult hook assembly includes: a support crank 700 and a detonating hook 800; one end of the support crank 700 is movably connected to the launch plate 500 through a first elastic part, and the other end of the support crank 700 is hinged to the detonating hook 800; one end of the detonating hook 800 is hinged to the launch plate 500; and the other end of the detonating hook 800 is provided with a hook portion 850. It should be noted that the launch plate 500 drives the actuation hook 800 to move at high speed, and the actuation hook 800 pushes the roller coaster 900 to move. The support crank 700 is used to provide an upward protruding auxiliary support force for the actuation hook 800 to improve the contact stability between the actuation hook 800 and the push rod 910, and avoid power transmission failure caused by poor contact. When the launch plate 500 and the actuation hook 800 stop moving, after the roller coaster train 900 starts moving, the actuation hook 800 disengages from the push rod 910. At this time, the actuation hook 800 falls rapidly under its own weight and the pulling action of the first elastic part. The actuation hook 800 presses down on the support crank 700, so that the actuation hook 800 and the support crank 700 fall smoothly into the relief groove 550 of the launch plate 500 to ensure that the structure at the bottom of the roller coaster 900 will not touch the actuation hook 800, so that it can continue to run smoothly.

[0073] like Figure 21 As shown, the top of the launch plate 500 has a rectangular recess 550 to accommodate the crank 700 and the actuating hook 800. The actuating hook 800 can be pressed into the recess 550 of the launch plate 500. Figure 20 As shown, the launch plate 500 has an elongated oval hole 560 through which the sixth connecting shaft 720 passes. The length direction of the elongated oval hole 560 is parallel to the length direction of the launch plate 500. The sixth connecting shaft 720 passes through the elongated oval hole 560 and can move inside it along the length direction of the elongated oval hole 560. The end of the support crank 700 is sleeved on the sixth connecting shaft 720 so as to be movably connected to the launch plate 500.

[0074] Furthermore, such as Figure 20 As shown, the support crank 700 consists of two opposing crank plates. One end of each crank plate is clamped to the opposite sides of the launch plate 500 and is hinged to the sixth connecting shaft 720. The other end of each crank plate is hinged to the actuating hook 800. Two limiting seats are fixedly provided on the sixth connecting shaft 720. The two limiting seats are located on both sides of the two crank plates to limit the two crank plates in the middle, thereby improving the installation stability of the sixth connecting shaft 720.

[0075] Furthermore, the first elastic part includes: a first spring 730, a first stop 740, and a first connecting rod 750; the first stop 740 is fixed on the launch plate 500, the first connecting rod 750 passes through the first stop 740 and connects to the sixth connecting shaft 720, the first spring 730 is sleeved on the first connecting rod 750 and one end of the first spring 730 abuts against the first stop 740, and the other end of the first spring 730 abuts against the end of the first connecting rod 750 away from the sixth connecting shaft 720; when the support crank 700 and the toggle hook 800 are both in the raised state, the first spring 730 is in the compressed state; when the roller coaster 900 starts, the first spring 730 pulls the support crank 700 to assist the toggle hook 800 in falling.

[0076] like Figure 21 As shown, one end of the actuating hook 800 is provided with a hook portion 850, and the other end of the actuating hook 800 is provided with a clamping groove. A seventh connecting shaft 830 is connected to the actuating hook 800. Two crank plates supporting the crank 700 are located on both sides of the actuating hook 800 and are sleeved on the seventh connecting shaft 830. The end of the actuating hook 800 with the clamping groove is clamped on the launching plate 500 and is hinged to the eighth connecting shaft 810 on the launching plate 500. The end of the actuating hook 800 near the supporting crank 700 is provided with a hook portion 850. The main body of the hook portion 850 is an arc-shaped groove structure, such as... Figure 23 As shown, the main body of the push rod 910 has a cylindrical structure, which is suitable for embedding into the arc-shaped groove of the toggle hook 800. Due to the special structure of the hook part 850, the toggle hook 800 can remain supported by the push rod 910 during the process of pushing the push rod 910 to move, and with the auxiliary support of the support crank 700, the connection between the toggle hook 800 and the push rod 910 is more stable.

[0077] In one possible implementation, such as Figure 21As shown, the ejector hook assembly also includes: a second spring 823, a second stop 824, a second connecting rod 822, and a locking handle 820; the middle part of the locking handle 820 is sleeved on the ninth connecting shaft 821, which is vertically mounted on the launch plate 500. The locking handle 820 can rotate on the launch plate 500 with the ninth connecting shaft 821 as the axis. The side of the locking handle 820 away from the actuating hook 800 is connected to the second connecting rod 822. The second connecting rod 822 passes through the second stop 824. The second spring 823 is sleeved on the outside of the second connecting rod 822, and one end of the second spring 823 is connected to the second stop 824. The first end is connected to the second link 822, and the second end is connected to the outer ring of the second link 822. Under the action of the second spring 823, the locking handle 820 can be rotated and tightened. The locking handle 820 has a protrusion 825 at one end facing the toggle hook 800, and a groove is opened at the other end facing the locking handle 820. After the toggle hook 800 falls and rotates, the protrusion 825 of the locking handle 820 will be embedded in the groove of the toggle hook 800. Under the action of the second spring 823, the locking handle 820 will lock and fix the toggle hook 800 to prevent it from rotating and tilting, so as to avoid interfering with the operation of the roller coaster 900.

[0078] In one possible implementation, such as Figure 20 As shown, the ejection hook assembly also includes: a return hook 710, one end of which is fixed to the side wall of the actuating hook 800 by four bolts; the end of the return hook 710 away from the actuating hook 800 has a protrusion 711, and the protrusion 711 is located on the side of the return hook 710 away from the supporting crank 700, as shown. Figure 24 As shown, the fixing member 920 is installed on the sleeper of the track. The return hook 710 is designed to contact the fixing member 920 on the sleeper of the track. After the roller coaster 900 has finished its departure, the launch plate 500 needs to be reset and moved to its original position to wait for the next departure. In order to ensure that the launch plate 500 is accurately reset and avoids excessive movement, the fixing member 920 is fixed at the corresponding position on the sleeper inside the track. During the reset and movement of the launch plate 500, when the protrusion 711 of the return hook 710 contacts the fixing member 920, it continues to move. At this time, the fixing member 920 pushes the return hook 710 in the direction of the supporting crank 700. The forward hook 710 is fixedly connected to the actuation hook 800, and the return hook 710 is sleeved on the eighth connecting shaft 810. Therefore, the return hook 710 will rotate around the eighth connecting shaft 810 as the axis, and drive the actuation hook 800 to rotate and lift upward around the eighth connecting shaft 810 as the center. At this time, it also indicates that the launch plate 500 has reached the original position and can stop resetting. After the actuation hook 800 is fully lifted upward, the launch plate 500 moves towards the push rod 910 of the already parked roller coaster 900 so that the actuation hook 800 is placed on the push rod 910, and the next launch movement can be carried out.

[0079] In one possible implementation, such as Figure 23 As shown, it also includes: an assisting protrusion structure 930, which is fixedly installed on the sleeper inside the roller coaster track and located below the initial position of the locking handle 820. The assisting protrusion structure 930 is a protrusion with a trapezoidal structure on the side. Before the return hook 710 contacts the fixing member 920, the locking handle 820 contacts the assisting protrusion structure 930 first. When the launch plate 500 moves during the reset process, the locking handle 820 contacts the assisting protrusion structure 930, which lifts the bottom end of the locking handle 820 and causes it to rotate. During the rotation of the locking handle 820, the protrusion 825 of the locking handle 820 disengages from the groove of the actuating hook 800. At this time, the locking handle 820 releases the actuating hook 800. Then, when the return hook 710 contacts the fixing member 920, the fixing member 920 can easily lift the actuating hook 800.

[0080] In one possible implementation, such as Figure 19 As shown, both sides of the bottom of the launching plate 500 are provided with fixing beams 510. The length direction of the fixing beams 510 is parallel to the length direction of the launching plate 500. One side of each fixing beam 510 is connected to the launching plate 500 by multiple ninth bolts 511. The bottom of each fixing beam 510 is provided with two or more clamping blocks 520, which are evenly arranged along the length direction of the fixing beams 510. The main body of each clamping block 520 is a Π-shaped block structure, and its top is connected to the two fixing beams 510 by multiple bolts. The inner side of the opening of each clamping block 520 is suitable for installing two braking magnets 530. The two braking magnets 530 are arranged parallel to each other, and their length direction is suitable for being parallel to the moving direction of the launching plate 500.

[0081] The working process of this application is described as follows: Before departure, the actuation hook 800 is securely hooked onto the push rod 910 at the bottom of the roller coaster 900. Then, high-pressure gas is injected into the cylinder 400, impacting the piston assembly 600 and causing it to move rapidly within the cylinder 400. The launch plate 500 moves at high speed, and the actuation hook 800 pushes the roller coaster 900 to move at high speed. When the launch plate 500 reaches the preset position and stops moving, the roller coaster 900 starts smoothly. After the actuation hook 800 rotates and falls, it remains in a low position. The locking handle 820 tightens and limits the actuation hook 800. Then, the drive device 140 drives... The traction rope 300 and the launch plate 500 are reset and moved. During the reset process, the toggle hook 800 remains in a low position, and the locking handle 820 continuously limits and locks the toggle hook 800. When the roller coaster completes one operation, returns to its original position, and stops completely, the locking handle 820 contacts the assisting protrusion structure 930 on the sleeper. The locking handle 820 is lifted by the assisting protrusion structure 930, causing it to rotate and release the toggle hook 800. The return hook 710 contacts the fixing member 920, and during the continued reset movement, the fixing member 920 lifts the toggle hook 800. After the toggle hook 800 is fully lifted, the reset is completed, and the launch plate 500 stops resetting and moving.

[0082] Currently, some roller coasters use linear synchronous motors for launch, which involves laying a series of carefully arranged electromagnetic coils on or below the launch track, and installing permanent magnets on the bottom or sides of the roller coaster. When the electromagnetic coils are energized, they generate a strong moving magnetic field. This moving magnetic field interacts with the permanent magnets on the coaster, generating a powerful electromagnetic thrust (Lorentz force). However, this drive method generates electromagnetic interference to the outside world. Due to the extremely high transient magnetic field strength during launch, it can easily interfere with wireless communication within the park. Furthermore, it requires a transformer of over 2000 kilowatts for power supply, resulting in a large power demand. This application, however, will not generate electromagnetic interference to external equipment and will not be affected by electromagnetic interference during normal launch operation.

[0083] Steam catapults, designed for aircraft carriers, can accelerate heavy carrier-based aircraft to takeoff speed in a very short distance. Essentially, they utilize the immense energy of high-pressure steam to directly propel objects. However, this requires a massive boiler room, steam storage tanks, and a complex piping system. For an amusement park, this would be too large a space, too costly, and the boiler would take a very long time to generate sufficient high-pressure steam, making it unsuitable for the high-frequency, continuous launch requirements of an amusement park. This application, however, eliminates the need for a complex energy storage system and only requires the use of an air compressor.

[0084] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
