Description

Technical Field

[0001] This utility model belongs to the field of amusement equipment, and in particular relates to an electromagnetic adsorption type double catapult amusement equipment. Background Technology

[0002] Catapult amusement rides are widely used in outdoor amusement parks. Through hydraulic or electromagnetic drive systems, they release energy instantaneously to achieve rapid lifting and lowering, providing riders with an extreme experience. Existing electromagnetic drive systems for catapult amusement rides typically consist of multiple magnetic devices mounted on the upper part of the base. The magnetic attraction between these devices and the catapult chassis creates a combined force that pulls the catapult on. However, their main drawbacks are: due to manufacturing and installation errors, there are distance differences between the various magnetic devices and the catapult chassis, resulting in varying attractive forces exerted by each device on the catapult. This leads to inconsistent electromagnetic attraction in the circumferential direction of the catapult, affecting the energy transfer efficiency of the electromagnetic drive system; the electromagnetic drive system experiences high no-load current and high temperature, easily burning out the electromagnetic coils; and the guide mechanism is prone to wear, resulting in a short equipment lifespan. Utility Model Content

[0003] This invention addresses the problems existing in the prior art by providing an electromagnetic adsorption-type double-person catapult amusement device that employs electromagnetic adsorption and hydraulic energy storage coordinated control, resulting in high energy transfer efficiency, reliable operation of the electromagnetic drive system, and long product lifespan.

[0004] The technical solution of this utility model is as follows: An electromagnetically adsorbed double-person catapult amusement device includes a catapult body, a catapult base, a support frame, and a tension device. A shock-absorbing seat is installed inside the catapult body. A chassis that mates with the upper surface of the catapult base is located at the bottom of the catapult body. The upper end of the catapult body is connected to the tension device via elastic ropes and tension steel cables. The catapult body is installed between the catapult base and the upper beam of the support frame via a vertical guide device. A hydraulic buffer is provided on the catapult base. The device is characterized by: at least three magnetic devices evenly distributed circumferentially within the upper surface of the catapult base; adjustable suction cups located directly above the magnetic devices, with their number equal to the number of magnetic devices; and a position sensing switch connected to the power control circuit of the magnetic devices via a switch signal.

[0005] A preferred embodiment is that the ejector body adopts a hollow sphere structure, and the shock-absorbing seat is installed on the bottom plane of the hollow sphere's inner cavity.

[0006] The preferred embodiment is that the tensioner is a hydraulic tensioning device, which consists of a hydraulic cylinder, a piston rod, and a hydraulic controller; one end of the tension steel rope is connected to the projectile body through an elastic rope, and the other end is connected to one end of the piston rod through a roller assembly, and the other end of the piston rod forms a piston structure with the inner cavity of the hydraulic cylinder.

[0007] In a preferred embodiment, the roller assembly consists of a first roller, a second roller, a third roller, and a fourth roller. The first roller is mounted on the upper crossbeam of the support frame directly above the projectile. The second roller is mounted on another crossbeam of the support frame above the piston rod. The third roller is mounted on one side of the hydraulic cylinder, and the fourth roller is mounted on the end of the piston rod. A lifting nut is provided on one side of the hydraulic cylinder. One end of the tension steel rope is connected to the elastic rope, and the other end passes through the grooves of the first roller, the second roller, the third roller, and the fourth roller in sequence and is fixedly connected to the lifting nut. The grooves of the first roller, the second roller, the third roller, and the fourth roller, as well as the center line of the piston rod, the vertical center line of the projectile, and the lifting nut are located in the same plane. The first roller, the second roller, the third roller, and the fourth roller are each provided with a steel rope guide cover.

[0008] In a preferred embodiment, the vertical guiding device consists of a four-wheel locator and steel wire ropes. There are at least two steel wire ropes, with both ends passing through the guide holes of the launcher and fixed to the upper crossbeam of the support frame and the launcher base, respectively.

[0015] like Figure 1 , Figure 2 , Figure 3The electromagnetic adsorption type double-person catapult amusement equipment shown includes a catapult body 1, a catapult base 2, a support frame 5, and a tension device. The catapult body 1 contains two shock-absorbing seats 11, which are installed on the base plate of the catapult body 1. Each shock-absorbing seat 11 is equipped with a safety belt 12 to reliably bind the user to the seat, preventing separation during launch and thus avoiding accidents. The bottom of the catapult body 1 has a chassis that mates with the upper surface of the catapult base 2. The upper longitudinal centerline of the catapult body 1 is connected to the tension device via an elastic rope 7 and a tension steel rope 9. The elastic rope 7 is stretched by the tension steel rope 9, causing the elastic rope 7 to generate elastic energy storage. The projectile 1 is installed between the upper crossbeam 10 of the projectile base 2 and the support frame 5 through a vertical guide device to maintain the longitudinal movement of the projectile 1. A hydraulic buffer 24 is provided on the projectile base 2 to prevent the projectile 1 from colliding with the projectile base 2 when it falls. The projectile base 2 is characterized by having magnetic devices 14 in its upper plane. There are at least three magnetic devices 14, which are evenly arranged in the circumferential direction in the upper plane of the projectile base 2. The three magnetic devices 14 are arranged in a triangular position to generate energy on the chassis of the projectile 1. The magnetic device 14, composed of an electromagnet core and an electromagnetic coil, provides a balanced suction force. When the electromagnetic coil is energized, it generates an electromagnetic force that holds the projectile 1 firmly against the projectile base 2. Adjustable suction cups 15 are installed on the lower plane of the base at the bottom of the projectile 1. The number of adjustable suction cups 15 is the same as that of the magnetic device 14. They are installed directly above the three magnetic devices 14 using adjusting bolts and fastening nuts. By adjusting the three adjusting bolts, the distance between the lower plane of the three adjustable suction cups 15 and the upper plane of their corresponding magnetic devices 14 is equal, ensuring that the three magnetic devices 14 exert a balanced suction force on the projectile 1. Equal forces improve electromagnetic energy conversion efficiency. A position sensing switch 23 is installed between the upper plane of the launch base 2 and the lower plane of the launch body 1 chassis. The switching signal of the position sensing switch 23 is connected to the power control circuit of the magnetic device 14. When the launch body 1 approaches the launch base 2, the switching signal of the position sensing switch 23 energizes the electromagnetic coil of the magnetic device 14 through the controller. When the launch body 1 leaves the launch base 2, the switching signal of the position sensing switch 23 de-energizes the electromagnetic coil of the magnetic device 14 through the controller, preventing the electromagnetic device 14 from overheating and burning out the electromagnetic coil due to no-load current. The launch base 2 is equipped with a base leveling bolt 13 to adjust the levelness of the upper plane of the launch base 2. An animal-shaped decorative top 16 is provided at the upper end of the launch body 1 to improve the aesthetics of the equipment.

[0016] The catapult 1 adopts a hollow sphere structure to reduce air resistance during the up-and-down movement of the catapult 1. Two shock-absorbing seats 11 are symmetrically installed on the bottom plane on both sides of the longitudinal center line of the hollow sphere to maintain the gravitational balance on both sides of the longitudinal center line of the catapult 1.

[0017] The tensioner employs a hydraulic tensioning device, which consists of a hydraulic cylinder 4, a piston rod, and a hydraulic controller 3. One end of the tension steel rope 9 is connected to the projectile 1 via an elastic rope 7, and the other end is connected to one end of the piston rod via a roller assembly. The other end of the piston rod forms a piston structure with the inner cavity of the piston cylinder 4. The hydraulic cylinder 4 is fixedly mounted on the bottom plane inside the support frame 5 via a hydraulic cylinder bracket 6. The hydraulic controller 3 is fixedly mounted on the bottom plane inside the support frame 5. The hydraulic controller 3 controls the longitudinal movement of the piston rod, pulling the tension steel rope 9 to achieve the stretching or contraction of the elastic rope 7.

[0018] The roller assembly consists of a first roller 17, a second roller 18, a third roller 19, and a fourth roller 20. The first roller 17 is mounted on the upper crossbeam 10 of the support frame 5 directly above the catapult 1. The second roller 18 is mounted on another crossbeam of the support frame 5 above the piston rod. The third roller 19 is mounted on one side of the hydraulic cylinder 4, and the fourth roller 20 is mounted on the end of the piston rod. A lifting nut 22 is provided on the other side of the hydraulic cylinder 4. The tension steel cable 9 passes sequentially through the grooves of the first roller 17, the second roller 18, the third roller 19, and the fourth roller 20 and is fixedly connected to the lifting nut 22. When the piston rod rises, it pushes the fourth roller 20 to lift the tension steel cable 9. This pulley structure principle allows the tension cable to be greater than twice the length of the piston rod. The tension rope 7 stores energy at a height of 10 times. When the controller de-energizes the electromagnetic coil of the magnetic device 14, the energy stored in the tension rope 7 and the gravity of the launcher 1 cause the launcher 1 to reciprocate longitudinally, giving the riders inside the launcher 1 an aerial flight experience. The grooves of the first roller 17, the second roller 18, the third roller 19, and the fourth roller 20, as well as the center line of the piston rod, the vertical center line of the launcher 1, and the nut 22 are all located in the same plane, reducing the resistance of each roller to the tension steel rope 9 and reducing the wear and pulling noise of the tension steel rope 9. The first roller 17, the second roller 18, the third roller 19, and the fourth roller 20 are each equipped with a steel rope guide cover 21 to prevent the tension steel rope 9 from detaching from the groove of the roller.

[0019] The vertical guiding device consists of a four-wheel positioner 25 and steel wire ropes 8. There are at least two steel wire ropes 8, with both ends passing through two longitudinal guide holes in the launcher 1 and fixed to the upper crossbeam 10 of the support frame 5 and the launch base 2, respectively. The two longitudinal guide holes are symmetrically arranged on both sides of the longitudinal centerline of the launcher 1. The plane formed by the two longitudinal guide holes and the longitudinal centerline of the launcher is a mirror plane of the two shock-absorbing seats 11. The four-wheel positioners 25 are respectively installed at the upper and lower ends of the longitudinal guide holes in the launcher 1 to achieve radial positioning of the steel wire ropes 8 and prevent frictional contact between the steel wire ropes 8 and the longitudinal guide holes of the launcher 1. The four-wheel positioner 25 consists of a mounting base 28 and guide wheels 27. The mounting base 28 has a central hole, and there are four guide wheels 27 evenly installed around the central hole of the mounting base 28. The steel wire ropes 8 pass through the central hole of the mounting base 28 and roll in cooperation with the four guide wheels 27, reducing the frictional force of the launcher 1 moving on the steel wire ropes 8. Figure 4 As shown.

[0020] Two elastic ropes 7 are used, with their lower ends connected to the catapult 1 via the catapult nut 26, and their upper ends connected to the tension steel rope 9 via the connecting plate 29. Figure 3 As shown, the two catapult supports 26 are symmetrically arranged on both sides of the longitudinal centerline of the catapult 1, so that the two elastic ropes 7 are subjected to uniform force, and the tension steel rope 9 coincides with the longitudinal centerline of the catapult 1.

[0021] The diameters of the wire rope 8 and tension rope 9 and the elastic modulus of the elastic rope 7 are determined based on the maximum weight of the catapult 1 when carrying two people plus a safety factor. The hydraulic tension device is equipped with a mechanical locking device to ensure safety performance in the event of hydraulic system failure such as pressure loss. The support frame 5 is fixedly installed on the ground, and a fence is set up around the support frame 5. These are known technologies and will not be described in detail.
