Description
Technical Field
[0001] This utility model relates to the field of amusement launcher technology, and in particular to a launcher ball. Background Technology
[0002] As people's living standards improve, their demand for amusement experiences is growing. Traditional amusement facilities such as Ferris wheels and roller coasters can no longer fully satisfy people's pursuit of thrills and novel experiences. High-altitude catapult balls, as a new type of amusement facility, have emerged to meet this need. Their design concept draws on the technologies of catapult devices and spherical amusement facilities. Based on early catapult devices, such as ejection seats in the military field and aircraft ejection devices on aircraft carriers, these have been adapted for civilian use, applying catapult power to amusement facilities. At the same time, the spherical structure of amusement facilities also provides aesthetic and some safety design ideas for high-altitude catapult balls; for example, some large transparent spherical amusement facilities allow people to experience the fun of rolling inside.
[0003] However, existing technologies have the following shortcomings: the braking system of a winch typically consists of brake pads, a brake disc, and related hydraulic or mechanical transmission devices. Excessive wear of the brake pads, deformation of the brake disc, or leakage in the hydraulic system can lead to brake failure. Prolonged and frequent use may thin the brake pads; when their thickness falls below a critical value, they cannot provide sufficient friction to stop the drum's rotation. Motor malfunctions, such as a stuck motor shaft or a short circuit in the motor windings, can also prevent the winch from stopping properly. A stuck motor shaft due to bearing damage will prevent the motor from operating normally, while a short circuit in the motor windings may cause the motor to run uncontrollably at high speed. If the launch ball rises uncontrollably and then falls, due to its great height, its impact speed upon landing will be extremely high, potentially causing severe fractures, internal organ rupture, or even death to passengers. Therefore, those skilled in the art have provided a launch ball to address the aforementioned problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a catapult ball. To achieve the above objective, this utility model provides the following technical solution: A safety seat is installed in the middle of both sides inside the catapult ball body, providing seating space for passengers and ensuring their safety during launch. The seat design conforms to ergonomics and is equipped with protective facilities such as seat belts, effectively securing the passenger's body and preventing injury due to inertia during acceleration, deceleration, and operation. A buffer base is installed in the middle of the bottom, matching the ground buffer seat. The buffer base is made of materials with good elasticity and cushioning performance, such as rubber or special shock-absorbing alloys. When the catapult ball is stationary on the buffer seat, it reduces the pressure on the ground caused by its own weight. During launch, whether it is the impact force at the moment of launch or the reaction force during braking or collision, the buffer base and buffer seat can absorb and disperse energy through their own elastic deformation, thereby protecting the structural integrity of the catapult ball body, reducing damage to ground facilities, and ensuring the stability and safety of the entire device.
[0005] Preferably, a traction groove is provided between the front and rear side walls of the launch ball body, and a traction rope is installed between the front and rear sides of the top of the buffer base, with the other end of the traction rope connected to the roof. The traction groove and traction rope work together to tightly connect the launch ball to the roof, providing stability and guidance. During the launch ball preparation phase, they limit the horizontal displacement of the launch ball, preventing it from deviating from the predetermined launch trajectory due to external factors such as wind or slight equipment shaking. During launch, the traction rope provides a certain lateral tension to the launch ball, causing it to accelerate along the preset direction, ensuring the accuracy and reliability of the launch, and preventing the launch ball from swaying, rotating, or other unstable states, thereby ensuring the safety of passengers.
[0006] Preferably, the winch body is installed on the inner wall of the winch fall arrester, which is one of the core power sources of the entire catapult power system. The output end of the winch body is connected to the transmission box, which plays the role of power transmission and speed change, and can adjust the power output to the traction drum and the speed according to different catapult requirements.
[0007] Preferably, when it is necessary to stop the rotation of the traction drum or brake it, the operator presses down the brake lever. Since the brake lever is connected to the drive shaft, the drive shaft drives the crank to rotate synchronously. The rotation of the crank pushes two semi-circular brake friction pads towards the inside of the traction drum and into contact with it via a connecting rod. The friction force generated between the brake friction pads and the inner wall of the traction drum can quickly stop the rotation of the traction drum, thereby braking the pull rope. This braking method has the characteristics of rapid response and large braking force, which can effectively prevent the pull rope from becoming excessively slack or out of control, and ensure the safety of the catapult ball in a timely manner in case of accidents such as winch failure, avoiding dangerous acceleration, falling, or collision of the catapult ball due to power system failure.
[0008] Preferably, a pull rope is fitted onto the outer wall of the traction drum, with the other end of the rope passing through the top of the winch's fall arrestor and connected to the conveying mechanism. As a crucial medium for power transmission, the pull rope, driven by the winch itself, converts the rotational motion of the traction drum into linear tension, pulling the conveying mechanism. The pull rope is made of high-strength, low-elongation materials, such as steel wire rope or special synthetic fiber rope, to ensure it will not break or over-elongate under significant tension, thus guaranteeing the stability and reliability of power transmission.
[0009] Preferably, the conveying mechanism is installed on the roof beam or the roof where the equipment is placed, and its output end is connected to the transmission mechanism. The conveying mechanism can run on the track or support structure on the roof, transmitting and converting the tension from the pull rope to provide a suitable power input for the transmission mechanism. The transmission mechanism is also installed on the roof, which further processes and regulates the power, converting it into an energy form suitable for launching the ball, and transferring the energy to the elastic rope to store elastic potential energy.
[0010] Preferably, the output end of the transmission mechanism is connected to an elastic rope, which stores the energy transmitted by the transmission mechanism using its own elastic properties. During the launch preparation phase, as the rope is pulled and the transmission mechanism operates, the elastic rope is gradually stretched, and elastic potential energy accumulates continuously. When the launch conditions are met, the elastic rope releases the stored elastic potential energy, rapidly contracts, and converts the energy into the kinetic energy of the launch ball, propelling it to launch. The elastic rope is made of a material with high elastic modulus, good fatigue life, and corrosion resistance, such as high-strength rubber or special elastic alloy wire, to ensure stable and reliable operation during multiple launch cycles.
[0011] Preferably, an elastic adjuster is installed near the top of the middle of the outer wall of the elastic rope. Adjusting rollers are installed at both the upper and lower ends of the inner wall of the elastic adjuster, with the upper roller driven by an adjusting motor located at the upper middle of the right side of the elastic adjuster. By precisely controlling the position or rotation of the upper adjusting roller through the adjusting motor, the winding angle and tension of the elastic rope between the rollers are changed, thereby achieving precise adjustment of the elasticity of the elastic rope. This adjustment method allows for flexible adjustment of the launch force and speed according to different launch scenarios, passenger weight, safety requirements, and other factors.
[0012] This utility model has the following beneficial effects:
[0013] 1. In this invention, when the winch malfunctions and continues to operate, the operator can immediately manually operate the spread-out brake assembly to ensure the brake block makes tight contact with the drum, generating friction and thus preventing the drum from continuing to rotate. This prevents the catapult ball from being excessively launched, avoiding a dangerous situation where it exceeds its design height. Timely braking also prevents the traction rope from breaking due to excessive tension. Keeping the rope intact ensures the catapult ball remains within a controllable range, preventing it from going out of control in the air.
[0014] 2. In this utility model, when the winch malfunctions and continues to operate, the fall arrestor below the catapult ball can slow down the catapult ball's descent speed, prevent the traction rope from being subjected to excessive tension and breaking, and keep the rope intact to ensure that the high-altitude catapult ball is within a controllable range and avoids it from going out of control in the air.
[0015] 3. In this utility model, the operator can adjust the tension of the elastic rope to make the catapult ball fall at a safe speed, avoiding the serious impact and injury to passengers caused by high-speed fall. The limiting device allows the operator to precisely control the catapult ball's launch height, so that it lands in a stable posture, reducing the risk of passengers being hit and crushed inside the ball due to an unstable landing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 — Figure 5 A catapult ball includes a catapult ball body 1, with safety seats 102 installed on both sides of the middle of its inner wall, providing safety protection for passengers during launch. A buffer base 104 is installed at the middle of the bottom of the catapult ball body 1, matching a buffer seat 101 on the ground. When the catapult ball is stationary or moving and generates impact, the buffer base 104 interacts with the buffer seat 101, effectively reducing damage to the catapult ball body 1 and the ground.
[0026] Furthermore, a winch fall arrestor 2 is installed on the ground, located on the right side of the launch ball body 1. A winch body 201 is installed on the inner wall of the winch fall arrestor 2. The output end of the winch body 201 is connected to a transmission box 202, and the output end of the transmission box 202 is connected to a traction drum 203. A drive shaft 208 is rotatably connected to the middle of the inner wall of the traction drum 203. A crank 205 is fixedly sleeved on the outer wall of the drive shaft 208. Connecting rods 207 are installed at the top middle of the front and rear side walls and at the bottom middle of the rear side wall of the crank 205. Brake friction pads 206 are pin-connected between the two sets of connecting rods 207. Both brake friction pads 206 have a semi-circular arc structure. A brake lever 204 is connected to the output end of the drive shaft 208. The output end of the brake lever 204 passes through the middle of the rear side wall of the winch fall arrestor 2, slightly to the left. When it is necessary to stop the rotation of the traction drum 203 or to brake it, the operator presses down the brake lever 204, causing the crank 205 to rotate synchronously. This drives the two sets of connecting rods 207 to simultaneously apply emergency braking to the inside of the traction drum 203 using the two semi-circular brake friction pads 206. The braking is achieved by using friction to prevent accidents such as excessive slack or loss of control of the pull rope 8 or winch failure, thus ensuring the safety and stability of the ejection process.
[0027] Furthermore, a pull rope 8 is sleeved on the outer wall of the traction drum 203. The other end of the pull rope 8 passes through the top of the winch fall arrester 2 and is connected to a conveying mechanism 7. The output end of the conveying mechanism 7 is connected to a transmission mechanism 6. Both the transmission mechanism 6 and the conveying mechanism 7 are installed on the roof beam or the roof of the equipment placement site. The conveying mechanism 7 runs on the roof beam or roof, transmitting energy from the transmission mechanism 6 and converting it into a suitable form of power. The two work together to prepare the power required for launch.
[0028] Furthermore, the output end of the transmission mechanism 6 is connected to an elastic rope 4, and an elastic adjuster 5 is installed near the top of the middle of the outer side wall of the elastic rope 4. Adjusting rollers are installed at both the upper and lower ends of the inner side wall of the elastic adjuster 5, and an adjusting motor is connected to the input end of the upper adjusting roller. The adjusting motor is installed at the upper right side of the elastic adjuster 5. By changing the relative position or rotation state of the adjusting rollers, precise control of the tension and elasticity of the elastic rope 4 can be achieved, thereby meeting different ejection requirements within a safe range.
[0029] Furthermore, traction grooves 103 are installed at the middle of the front side wall and the middle of the rear side wall of the catapult ball body 1, and traction ropes 3 are installed at the middle of the front and rear sides of the top of the buffer base 104. The other end of the traction ropes 3 is connected to the roof, and its function is to connect the catapult ball to the roof, so as to play a certain role in stabilization and guidance.
[0030] Working principle: First, passengers enter the ejection ball body 1, sit in the safety seat 102, and put on their seat belts and other protective equipment. Then, the winch body 201 is started. The transmission box 202 connected to its output end transmits power to the traction drum 203. The traction drum 203 starts to rotate and tightens the pull rope 8. The pull rope 8 acts on the transmission mechanism 6 and starts to work. The elastic rope 4 connected to its output end stores elastic potential energy. Then, the conveying mechanism 7 runs on the roof of the beam or equipment placement site, transmitting the energy from the transmission mechanism 6 and converting it into a suitable form of power. The output end of the conveying mechanism 7 is connected to the transmission mechanism 6. The two work together to prepare the power required for ejection. The output end of the conveying mechanism 7 is connected to the pull rope 8. The other end of the pull rope 8 passes through the top of the winch fall arrester 2 and is connected to the conveying mechanism 7. The elasticity adjuster 5 can adjust the elasticity of the elastic rope 4. Adjusting rollers are installed at the upper and lower ends of its inner side wall. The upper adjusting roller is driven by the adjusting motor installed at the middle upper end of the right side of the elasticity adjuster 5. By changing the relative position or rotation state of the adjusting roller, the tightness and elasticity of the elastic rope 4 can be precisely controlled, thereby controlling different ejection requirements within a safe range. The ejection ball body 1 is placed on the ground buffer seat 101 through the bottom buffer base 104. The buffer base 104 and the buffer seat 101 match each other and can play a buffering role when the ejection ball is stationary or moving and generates impact, reducing damage to the ejection ball body 1 and the ground. The traction groove 103 located between the front and rear side walls of the catapult ball body 1 and the traction rope 3 located between the front and rear sides of the top of the buffer base 104 connect the catapult ball to the roof, providing a certain degree of stability and guidance.
[0031] When it is necessary to stop the rotation of the traction drum 203 or to brake it, the operator presses down the brake lever 204, causing the crank 205, which is fixedly sleeved on the outer wall of the drive shaft 208, to rotate synchronously. Connecting rods 207 are installed at the top midpoint of the front and rear side walls and at the bottom midpoint of the rear side wall of the crank 205. As the crank 205 rotates, the two sets of connecting rods 207 drive two semi-circular brake friction pads 206 to simultaneously apply emergency braking to the interior of the traction drum 203. This braking utilizes friction to prevent the pull rope 8 from becoming excessively slack or out of control, or to prevent winch malfunction or other unexpected situations, ensuring the safety and stability of the launching process. Through the coordinated operation of all components, the launching of the ball and related safety control and power adjustment functions are ultimately achieved.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
