Description
Technical Field
[0001] This application relates to the field of amusement equipment technology, and in particular to a catapult hook device for launching roller coasters. Background Technology
[0002] In modern roller coaster technology, the catapult launch method is becoming increasingly widely used due to its faster instantaneous start and more intense thrill. The catapult launch system can accelerate the roller coaster from a standstill to a predetermined high speed in a short period of time on the launch track, providing an instantaneous burst of power and a high-speed experience that cannot be matched by traditional chain lifts.
[0003] In existing technology, a launch structure is installed in the track groove, and a power unit is connected to the launch structure. A pawl structure is located on the top of the launch structure, which is designed to contact or engage the thrust rod at the bottom of the roller coaster train. When the power unit drives the launch structure to move at high speed, the launch structure propels the roller coaster train at high speed via the pawl. When the power unit drives the launch structure to a momentary stop, the roller coaster train disengages from the pawl due to inertia and departs at extremely high speed. Therefore, to ensure that the pawl on the launch structure can contact the thrust rod at the bottom of the roller coaster train, the pawl needs to... The roller coaster extends from the launch structure and tilts up to the height of the push rod. After the launch is completed, the launch structure needs to return to the initial launch position. After the roller coaster completes its journey, it also needs to return to the launch position to wait for the next launch. During the return to the launch position, the train will pass over the claw. Therefore, the claw needs to descend quickly after the launch to avoid interference with the roller coaster returning to the launch position. However, if the claw is not fixed and locked after it descends, it may tilt up again due to vibration caused by the movement of the roller coaster. This may cause the roller coaster equipment structure to interfere with and collide with the claw.
[0004] This application proposes a catapult hook device for launching a roller coaster, which is suitable for locking and fixing the pawl after the roller coaster has launched and descended, so as to prevent the pawl from lifting during the return journey. Summary of the Invention
[0005] In view of this, this application proposes a catapult hook device for launching roller coasters.
[0006] According to one aspect of this application, a catapult hook device for launching a roller coaster is provided, comprising: a connecting plate, a pawl, a support member, a limiting handle, a first elastic part and a second elastic part; both ends of the connecting plate are adapted to connect to a catapult drive device so as to be driven by the catapult drive device to move at high speed in a straight line. One end of the pawl is located on the top of the connecting plate and is rotatably connected to the connecting plate. The other end of the pawl is provided with a hook for contacting the push rod at the bottom of the roller coaster. The pawl is suitable for attaching to the push rod at the bottom of the roller coaster through the hook so that the connecting plate drives the roller coaster to move at high speed in a straight line through the pawl. When the connecting plate stops moving and the pawl disengages from the push rod at the bottom of the roller coaster, the pawl falls under its own weight. One end of the support member is connected to the clearance hole of the connecting plate through the first pin, and the other end of the support member is hinged to the pawl. The first pin is connected to the connecting plate through the first elastic part. The limiting handle and the connecting plate are rotatably connected, and the side of the limiting handle away from the pawl is connected to the second elastic part. One end of the limiting handle is provided with a limiting protrusion, and the end of the pawl away from the support is provided with a limiting groove that matches the limiting protrusion. The second elastic part is used to press the limiting handle tightly to prevent the limiting handle from rotating freely.
[0007] In one possible implementation, the claw includes: an integrally formed clamping portion and a contact portion; The clamping part is clamped on the connecting plate and hinged to the connecting plate through the second pin. The side of the contact part away from the clamping part is provided with a hook part, and the main body of the hook part has an arc-shaped groove structure.
[0008] In one possible implementation, the contact portion of the pawl is hinged to the support via a third pin.
[0009] In one possible implementation, the support includes two opposing and parallel clamping plates with a preset gap between them, and the pawl and the connecting plate are clamped between the two clamping plates.
[0010] In one possible implementation, the clearance hole is an oblong hole structure, and the length direction of the clearance hole is parallel to the length direction of the connecting plate. In one possible implementation, the first elastic part includes: a first spring, a first fixing block, and a first connecting rod; The first fixing block is fixed on the connecting plate, the first connecting rod passes through the first fixing block and is connected to the first pin, the first spring is sleeved on the first connecting rod and one end of the first spring abuts against the first fixing block, and the other end of the first spring abuts against the end of the first connecting rod away from the first pin.
[0011] In one possible implementation, a relief groove is provided on the top of the connecting plate, and the pawl and the support are located on both sides of the relief groove, with the pawl being able to be embedded in the relief groove.
[0012] In one possible implementation, the second elastic part includes: a second spring, a second fixing block, and a second connecting rod; The second fixing block is fixed on the connecting plate, the second connecting rod passes through the second fixing block and is connected to the limiting handle, the second spring is sleeved on the second connecting rod and one end of the second spring abuts against the second fixing block, and the other end of the second spring abuts against the end of the second connecting rod near the limiting handle.
[0013] In one possible implementation, the first elastic portion and the second elastic portion are located on opposite sides of the connecting plate.
[0014] In one possible implementation, both ends of the connecting plate are provided with hooks for connecting the catapult drive device.
[0015] Beneficial effects: The connecting plate is suitable for connecting the launch drive equipment, and the protruding claws on the connecting plate are suitable for connecting the push rod at the bottom of the roller coaster. Thus, when the launch drive equipment drives the connecting plate to move at high speed, the connecting plate drives the claws to move at high speed, and the claws push the roller coaster train to move. The support component is suitable for providing upward protrusion auxiliary support force for the claws to improve the contact stability between the claws and the push rod and avoid power transmission failure caused by poor contact. When the connecting plate and the claws stop moving, after the roller coaster train starts moving, the claws disengage from the push rod. At this time, the claws fall rapidly under the action of their own weight and the pulling action of the first elastic part, and the support component moves within the clearance hole. After the pawl rotates as it descends, the limiting groove of the pawl rotates to the position of the upper limiting protrusion on the limiting handle. The limiting protrusion on the limiting handle then embeds itself into the limiting groove. Under the pressing action of the second elastic part on the limiting handle, the limiting handle firmly locks the pawl, preventing the pawl from resetting, rotating, or tilting, thus maintaining the pawl in its current state. This ensures that subsequent structures of the roller coaster train will not touch the pawl again. This application features a compact overall structure that is adaptable to high-speed moving environments, avoids impact and wear between equipment, reduces the risk of malfunctions during the roller coaster's launch process, and enhances operational safety.

Those skilled in the art should understand that the present invention can be practiced without certain specific details. In some instances, methods, means, elements, and circuits well known to those skilled in the art have not been described in detail in order to highlight the spirit of the invention.
[0025] Figure 1 This diagram shows the main structure of the catapult hook device for launching roller coasters according to an embodiment of this application; Figure 2 This diagram shows the main structure of the catapult hook device for launching roller coasters according to an embodiment of this application; Figure 3 This application shows a partial structural diagram of a catapult hook device for launching roller coasters according to an embodiment of the present application; as shown... Figure 1 As shown, a catapult hook device for launching a roller coaster includes: a connecting plate 100, a pawl 200, a support member 300, a limiting handle 500, a first elastic part, and a second elastic part. Both ends of the connecting plate 100 are adapted to connect to a catapult drive device, so that it can be driven by the catapult drive device to move at high speed in a straight line. One end of the pawl 200 is disposed on the top of the connecting plate 100 and rotatably connected to the connecting plate 100. The other end of the pawl 200 is provided with a hook portion 220 for contacting the push rod 910 at the bottom of the roller coaster 900. The pawl 200 is adapted to be mounted on the push rod 910 at the bottom of the roller coaster 900 via the hook portion 220, so that the connecting plate 100 can be driven by the pawl 200 to launch the roller coaster 900. The roller coaster 900 moves in a straight line at high speed; one end of the support member 300 is connected to the clearance hole 120 of the connecting plate 100 through the first pin 310, and the other end of the support member 300 is hinged to the pawl 200; the first pin 310 is connected to the connecting plate 100 through the first elastic part; the limiting handle 500 is rotatably connected to the connecting plate 100, and the side of the limiting handle 500 away from the pawl 200 is connected to the second elastic part; one end of the limiting handle 500 is provided with a limiting protrusion 510, and the end of the pawl 200 away from the support member 300 is provided with a limiting groove 242 that matches the limiting protrusion 510; the second elastic part is used to press the limiting handle 500 to prevent the limiting handle 500 from rotating freely.
[0026] It should be noted that the connecting plate 100 is suitable for connecting the catapult drive device, and the protruding pawl 200 on the connecting plate 100 is suitable for connecting the push rod 910 at the bottom of the roller coaster 900. Furthermore, the hook portion 220 of the pawl 200 can rest on the push rod 910. At this time, under the action of the push rod 910, the hook portion 200 remains raised and in contact with the push rod 910. The support member 300 is suitable for providing an upwardly protruding auxiliary support force for the pawl 200 to improve the contact stability between the pawl 200 and the push rod 910, avoiding power transmission failure caused by poor contact. Therefore, when the catapult drive device drives the connecting plate 100 to move at high speed, the connecting plate 100 drives the pawl 200 to move at high speed. The pawl 200 moves the roller coaster 900. Since the pawl 200 can be rotatably connected to the connecting plate 100, when the connecting plate 100 and the pawl 200 stop moving, after the roller coaster train 900 starts moving, the pawl 200 disengages from the push rod 910. At this time, the pawl 200 rotates and falls rapidly under its own weight and the pulling action of the first elastic part on the support member 300, no longer maintaining an upward convex state. Other equipment structures at the bottom of the roller coaster 900 will no longer contact the pawl 200. At the same time, the support member 300 moves within the clearance hole 120. The clearance hole 120 is to provide space for the horizontal movement of the support member 300, ensuring that the pawl 200 can smoothly press down the support member 300. After the pawl 200 falls and rotates, the limiting groove 242 rotates to the position of the limiting protrusion 510. The limiting protrusion 510 on the limiting handle 500 then embeds into the limiting groove 242. Under the pressing action of the second elastic part on the limiting handle 500, the limiting handle 500 remains in its current state and does not rotate, thus firmly locking the pawl 200 and preventing the pawl 200 from resetting and rotating. This prevents the pawl 200 from lifting up again due to vibration or other reasons, thus ensuring that the subsequent structure of the roller coaster train will not touch the pawl 200 again.
[0027] The overall structure of this application is compact and adaptable to high-speed moving environments, which can effectively avoid collision and wear between various devices, reduce the risk of failure during the roller coaster launch process, and enhance operational safety.
[0028] In one possible implementation, such as Figure 6As shown, the pawl 200 includes an integrally formed clamping portion 240 and a contact portion 250. The clamping portion 240 is clamped onto the connecting plate 100 and hinged to the connecting plate 100 via a second pin 210. The contact portion 250 has a hook portion 220 on its side away from the clamping portion 240, and the contact portion 250 has a through hole 251 for the third pin to pass through. The end of the clamping portion 240 has a clamping groove, and the clamping portion 240 has a through hole 241 for the second pin 210 to pass through. The connecting plate 100 is embedded in the clamping groove of the clamping portion 240 and hinged to the clamping portion 240 via the second pin 210.
[0029] Furthermore, the main body of the contact portion 250 has a block-shaped structure. It should be noted that a preset angle is provided between the length direction of the contact portion 250 and the length direction of the clamping portion 240 to ensure that the contact portion 250 is in a horizontal state when the claw 200 is kept in a raised and protruding state.
[0030] Furthermore, such as Figure 6 As shown, the main body of the hook part 220 has an arc-shaped groove structure, such as... Figure 10 and Figure 11 As shown, the main body of the push rod 910 has a cylindrical structure, which is suitable for embedding into the arc-shaped groove 220 of the contact part 250. Due to the special structure of the hook part 220, the pawl 200 can remain supported by the push rod 910 during the process of pushing the push rod 910 to move. With the auxiliary support of the support member 300, the connection between the pawl 200 and the push rod 910 is more stable.
[0031] Preferably, the material of the claw 200 is steel.
[0032] Furthermore, the second pin 210 is a bolt shaft, which passes through the through hole 241 of the pawl 200 and the through hole 130 of the connecting plate 100. The nut 212 is sleeved on the bolt shaft to lock the bolt shaft on the pawl 200, so that the pawl 200 rotates around the second pin 210.
[0033] In one possible implementation, the contact portion 250 of the pawl 200 is hinged to the support member 300 via a third pin. Furthermore, washers 230 are provided on both sides of the support member 300, and the third pin passes through the washers 230, the support member 300, and the pawl 200 in sequence, thereby connecting the three and allowing the support member 300 to rotate about the third pin.
[0034] In one possible implementation, such as Figure 3As shown, the support member 300 includes two opposing and parallel clamping plates with a preset gap between them. The pawl 200 and the connecting plate 100 are both clamped between the two clamping plates. It should be noted that the main body of the clamping plate has an elongated oval plate structure, and through holes are opened at both ends for the third pin and the first pin 310 to pass through.
[0035] In one possible implementation, such as Figure 3 As shown, the first elastic part includes: a first spring 420, a first fixing block 400 and a first connecting rod 410; the first fixing block 400 is fixed on the connecting plate 100, the first connecting rod 410 passes through the first fixing block 400 and is connected to the first pin 310 of the support member 300, the first spring 420 is sleeved on the first connecting rod 410 and one end of the first spring 420 abuts against the first fixing block 400, and the other end of the first spring 420 abuts against the end of the first connecting rod 410 away from the first pin 310.
[0036] Furthermore, the first pin 310 is a bolted shaft that passes through the through hole and the clearance hole 120 of the support member 300 and is locked and fixed with a matching nut. The end of the first connecting rod 410 is sleeved on the first pin 310.
[0037] Furthermore, the main body of the first fixing block 400 is a cube. The first fixing block 400 is connected to the connecting plate 100 by two screws, and the first fixing block 400 has a through hole for the first connecting rod 410 to pass through. When both the support member 300 and the pawl 200 are in the raised state, the first spring 420 is in the compressed state. When the roller coaster 900 starts, the first spring 420 pulls the support member 300 to assist the pawl 200 in falling quickly.
[0038] The limiting handle 500 is rotatably connected to the connecting plate 100. One end of the limiting handle 500 has a limiting protrusion 510, and the end of the pawl 200 away from the support member 300 has a limiting groove 242 that matches the limiting protrusion 510. It should be noted that setting the limiting handle 500 to limit the position of the pawl 200 further improves safety performance. Furthermore, as... Figure 7As shown, the main body of the limiting handle 500 is rod-shaped. A through hole 530 is provided in the middle of the limiting handle 500 for the fourth pin 520 to pass through. The limiting handle 500 is rotatably connected to the connecting plate 100 via the fourth pin 520. The fourth pin 520 is a bolt shaft, which passes sequentially through the through hole 530 of the limiting handle 500 and the through hole 140 of the connecting plate 100. A nut locks the fourth pin 520 in place. When the pawl 200 falls and rotates, the limiting groove 242 rotates to the position of the limiting protrusion 510. The limiting protrusion 510 on the limiting handle 500 then embeds into the limiting groove 242. Under the pressing action of the second elastic part on the limiting handle 500, the limiting handle 500 maintains its current state and does not rotate, thus firmly locking the pawl 200. The limiting handle 500 has two connecting parts 540 protruding from the side opposite to the limiting protrusion 510. The two connecting parts 540 are arranged opposite each other and each has a through hole 541 for the fifth pin to pass through.
[0039] In one possible implementation, the limiting handle 500 is connected to the connecting plate 100 via a second elastic portion, the second elastic portion being adapted to press against the limiting handle 500 to prevent the limiting handle 500 from rotating freely. Further, as... Figure 4 As shown, the second elastic part includes: a second spring 620, a second fixing block 600, and a second connecting rod 610; the second fixing block 600 is fixed on the connecting plate 100, the second connecting rod 610 passes through the second fixing block 600 and is hinged to the fifth pin on the limiting handle 500, the second spring 620 is sleeved on the second connecting rod 610 and one end of the second spring 620 abuts against the second fixing block 600, and the other end of the second spring 620 abuts against the end of the second connecting rod 610 near the limiting handle 500.
[0040] Furthermore, the main body of the second fixing block 600 is a cube. The second fixing block 600 is connected to the connecting plate 100 by two screws 630. The second fixing block 600 has a through hole for the second connecting rod 610 to pass through. When the pawl 200 falls and rotates, the pawl 200 first compresses the second spring 620 through the limiting handle 500. When the limiting groove 242 on the pawl 200 rotates to the position of the limiting protrusion 510, the second spring 620 elastically resets and pushes the limiting handle 500 towards the pawl 200, thereby causing the limiting protrusion 510 to be embedded in the limiting groove 242.
[0041] Furthermore, one end of the second connecting rod 610 is provided with an insertion part, which is inserted between the two connecting parts 540 of the limiting handle 500 and sleeved on the fifth pin. Preferably, the fifth pin is also a bolt shaft.
[0042] In one possible implementation, the first elastic portion and the second elastic portion are located on opposite sides of the connecting plate 100. This arrangement can balance the weight on both sides of the connecting plate 100 and prevent the connecting plate 100 from tipping over during movement.
[0043] In one possible implementation, the main body of the connecting plate 100 is a rectangular plate structure. A relief groove 110 is provided on the top of the connecting plate 100. The pawl 200 and the support member 300 are located on both sides of the relief groove 110, and the pawl 200 can be embedded in the relief groove 110. The relief groove 110 on the connecting plate 100 is designed to provide placement space for the pawl 200, ensuring that the pawl 200 can be completely embedded in the connecting plate 100 after it is lowered.
[0044] In one possible implementation, the connecting plate 200 has a clearance hole 120, and the clearance hole 120 is located beside the clearance groove 110. The main body of the clearance hole 120 has an elongated oval hole structure. The first pin 310 passes through the clearance hole 120, and the clearance hole 120 is suitable for providing space for the movement of the first pin 310.
[0045] In one possible implementation, the center of the connecting plate 100 is provided with two or more weight-reducing holes 150, thereby reducing the overall weight of the connecting plate 100.
[0046] In one possible implementation, both ends of the connecting plate 100 are provided with connectors 800 for connecting to the catapult drive device, such as... Figure 9 As shown, the connecting plate 100 has a sixth pin 810 at both ends. The sixth pin passes through the hole 160 at the end of the connecting plate 100 and is perpendicular to the connecting plate 100. The main body of the connector 800 is a Y-shaped rod structure. The open end of the connector 800 is sleeved on the sixth pin 810 and is located on opposite sides of the connecting plate 100. The other end of the connector 800 is provided with a connecting hole 801 for connecting the catapult drive device. Two limiting wheels 820 are sleeved on the sixth pin 810 and are located on both sides of the connector 800. Two washers 811 are sleeved on the sixth pin 810 and are located on one side of the two limiting wheels 820. Two retaining rings 812 are fixedly sleeved on both ends of the sixth pin 810 to limit the position of the connector 800 on the sixth pin 810.
[0047] Furthermore, the four corners of the connecting plate 100 are provided with a sixth pin 810, and the connector 800 can be connected to the two sixth pins 810 on the upper and lower sides.
[0048] In one possible implementation, such as Figure 3As shown, it also includes: a reset clip 700; one end of the reset clip 700 is fixedly disposed on the side wall of the pawl 200, and the end of the reset clip 700 away from the pawl 200 has a protrusion 710 and the protrusion 710 is located on the side of the reset clip 700 away from the support member 300, as shown. Figure 11 As shown, the fixing block 920 is set on the sleeper of the track. The reset clip 700 is adapted to contact the fixing block 920 on the sleeper of the track. After the roller coaster 900 has finished its departure, the connecting plate 100 needs to be reset and moved to its original position to wait for the next departure. In order to ensure that the connecting plate 100 is accurately reset and avoids excessive movement, a fixing block 920 is fixedly installed at the corresponding position on the sleeper inside the track. During the reset movement of the connecting plate 100, when the protrusion 710 of the reset clip 700 contacts the fixing block 920, it continues to move. At this time, the fixing block 920 pushes the reset clip 700 towards the support member 300. Since the reset clip 700 is fixedly connected to the pawl 200, and the reset clip 700 is sleeved on the second pin 210, the reset clip 700 will rotate around the second pin 210 as the axis, and drive the pawl 200 to rotate and lift upward around the second pin 210 as the center; at this time, it means that the connecting plate 100 has reached the original position and the reset movement can be stopped; after the pawl 200 is fully lifted upward, the connecting plate 100 moves towards the push rod 910 of the already parked roller coaster 900 so that the pawl 200 is placed on the push rod 910, and the next launch movement can be carried out.
[0049] Furthermore, such as Figure 8 As shown, the reset clip 700 and the pawl 200 are fixedly connected by four bolts 720. The reset clip 700 is sleeved on the second pin 210, and the washer 211 is sleeved on the second pin 210 and is set close to one side of the reset clip 700.
[0050] In one possible implementation, such as Figure 10 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 limit handle 500. The assisting protrusion structure 930 is a protrusion with a trapezoidal structure on the side. Before the reset clip 700 contacts the fixing block 920, the limit handle 500 contacts the assisting protrusion structure 930 first. When the connecting plate 100 moves during reset, the limit handle 500 contacts the assisting protrusion structure 930, which lifts the bottom end of the limit handle 500 and causes it to rotate. During the rotation of the limit handle 500, the limit protrusion 510 disengages from the limiting groove 242 of the pawl 200. At this time, the limit handle 500 releases the pawl 200. Then, when the reset clip 700 contacts the fixing block 920, the fixing block 920 can easily lift the pawl 200.
[0051] In summary, the working process of this application is described as follows: During the start-up process, the pawl 200 hooks onto the push rod 910, the connecting plate 100 is driven to move at high speed by the ejection drive device, and the pawl 200 pushes the roller coaster 900 to move at high speed. When the connecting plate 100 moves to the preset position, the connecting plate 100 stops moving. At this time, the roller coaster 900 starts smoothly and the pawl 200 remains in a low position after falling. The limit handle 500 tightens and limits the pawl 200. During the reset process of the connecting plate 100, the pawl 200 remains in a low position, and the limit handle 500 continuously limits and locks the pawl 200. After the roller coaster 900 completes one stroke, it returns to the ejection position. After the position is reached and the vehicle is completely stopped, the limit handle 500 on the resetting moving connecting plate 100 will contact the assisting protrusion structure 930 on the sleeper. The limit handle 500 is lifted by the assisting protrusion structure 930, causing it to rotate and release the pawl 200. Then, the resetting clip 700 contacts the fixing block 920. During the continued resetting movement of the connecting plate 100, the fixing block 920 lifts the pawl 200. After the pawl 200 is fully lifted, the resetting is completed, and the resetting movement of the connecting plate 100 stops. Finally, the connecting plate 100 is moved toward the push rod 910 of the already parked roller coaster 900, so that the pawl 200 can be smoothly placed on the push rod 910. Therefore, before practical application, the relative positional relationship between the position of the fixed block 920 and the initial position of the push rod 910 of the roller coaster 900 after it is parked needs to be precisely determined. It is necessary to ensure that the push rod 910 does not interfere with the reset and lifting process of the pawl 200, and also to ensure that the reset clip 700 does not detach from the fixed block 920 before the pawl 200 hooks onto the push rod 910, so as to avoid the phenomenon that the pawl 200 falls back on its own before hooking onto the push rod 910, resulting in failure to hook smoothly.
[0052] After the roller coaster 900 successfully starts, the pawl 200 quickly descends, thus avoiding motion interference between the pawl 200 and the roller coaster 900 during the start-up process. The limit handle 500 tightens and limits the pawl 200, preventing it from lifting during the subsequent reset process, effectively avoiding motion interference between the pawl 200 and the roller coaster 900 during the reset process. It also allows the pawl 200 to lift when the connecting plate 100 returns to the launch position, so that the pawl 200 can contact the push rod 910 at the bottom of the roller coaster 900 for the next launch.
