Technical Field

The utility model relates to the technical field of play ejection devices, in particular to an ejection ball.

Background

With the improvement of living standard of people, the demand for amusement experience is growing. Traditional amusement rides such as ferris wheels, roller coasters, etc. have not fully met the needs of people pursuing a stimulating and novel experience. The high-altitude catapulting ball is used as a novel recreation facility. The design concept of the ball game device uses the related technologies of the ejection device and the ball game facility. Based on the early catapulting devices, such as catapulting seats in the military field, aircraft catapulting devices on aircraft carriers and the like, the catapulting power is applied to recreation facilities through civil transformation. Meanwhile, the amusement facility with the ball structure also provides appearance and part of safety design ideas for high-altitude shooting balls, for example, some large transparent ball amusement facilities can enable people to experience funs such as rolling and the like.

However, the prior art has the disadvantage that the brake system of the hoisting machine usually consists of brake pads, brake discs and associated hydraulic or mechanical transmission. Brake failure can result if the brake pads wear excessively, the brake discs deform, or the hydraulic system leaks. The brake block can be thinned when the brake block is frequently used for a long time, when the thickness of the brake block is lower than a critical value, enough friction force cannot be provided to prevent the winding drum from rotating, if a motor self malfunctions, such as the motor shaft is blocked, a motor winding is short-circuited, and the like, the winch can not be normally stopped, the motor shaft is blocked due to the damage of a bearing, but if the motor winding is short-circuited, the motor can not be normally operated, but the motor can be possibly caused to be operated at an uncontrolled high speed, if the ejection ball falls after rising out of control, the speed of the ejection ball during falling down can be very high due to the excessively high height, and the impact force generated by the high-speed falling can cause serious fracture, viscera rupture and other injuries of passengers, and even endanger life. Accordingly, a skilled person provides a launch ball to solve the above-mentioned problems.

Disclosure of utility model

The utility model aims to solve the defects in the prior art, and provides an ejection ball which comprises a safety seat arranged at the middle positions of two sides inside an ejection ball body, so as to provide a riding space for passengers and ensure the safety of the passengers in the ejection process. The seat design accords with human engineering, is equipped with protection facilities such as safety belt, can effectively fix the passenger's health, prevents to launch acceleration, deceleration and in-process passenger and hurt because of inertia, installs the buffering base in the middle of the bottom, and its and the buffer base on ground mutually matches. The buffer base is made of a material with good elasticity and buffer performance, such as rubber or special shock absorbing alloy. The impact force at the moment of starting or the reaction force during braking or collision can be absorbed and dispersed by the buffer base and the buffer seat, so that the structural integrity of the ejection ball body is protected, the damage to ground facilities is reduced, and the stability and the safety of the whole device are ensured.

Preferably, traction grooves are formed in the middle positions of the front side wall and the rear side wall of the ejection ball body, traction ropes are arranged in the middle positions of the front side and the rear side of the top of the buffering base, and the other ends of the traction ropes are connected to the roof. The traction groove and the traction rope act together to tightly connect the ejection ball with the roof, so as to play a role in stabilizing and guiding. In the preparation stage of the ejection balls, the horizontal displacement of the ejection balls can be limited, and the ejection balls are prevented from deviating from a preset ejection track due to external factors such as wind power, slight shaking of equipment and the like. In the ejection process, the traction rope provides a certain lateral pulling force for the ejection ball, so that the ejection ball accelerates along a preset direction, the ejection accuracy and reliability are ensured, unstable states such as swinging, rotation and the like of the ejection ball are avoided, and the safety experience of passengers is ensured.

The rotation of the crank drives the two semicircular arc braking friction plates to approach and attach to the inside of the traction roller through the connecting rod. The friction force generated between the braking friction plate and the inner wall of the traction roller can prevent the rotation of the traction roller rapidly, thereby realizing the braking of the pull rope. The braking mode has the characteristics of quick response and large braking force, can effectively prevent the pull rope from excessively loosening or being out of control, and can timely ensure the safety of the ejection ball under the unexpected conditions of failure of a winch and the like, thereby avoiding dangerous acceleration, falling or collision of the ejection ball caused by power system faults.

The stay cord is used as an important medium for power transmission, and the rotation motion of the traction roller is converted into linear tension under the driving of the winch body, so that the conveying mechanism is pulled to operate. The stay cord is made of high-strength low-elongation materials, such as steel wire ropes or special synthetic fiber ropes, so that the stay cord cannot break or excessively stretch when bearing large tensile force, and stability and reliability of power transmission are guaranteed.

Preferably, the conveying mechanism is arranged on the roof of a house beam or a place where equipment is placed, and the output end of the conveying mechanism is connected with the transmission mechanism. The conveying mechanism can run on a track or a supporting structure of the roof, and the pulling force from the pulling rope is transmitted and converted to provide proper power input for the transmission mechanism. The transmission mechanism is also arranged on the roof, and further processes and adjusts the power, converts the power into an energy form suitable for ejection of the ejection ball, and transmits the energy to the elastic rope to store elastic potential energy.

Preferably, the output end of the transmission mechanism is connected with a bungee cord, and the bungee cord stores energy transmitted by the transmission mechanism by utilizing the own elastic characteristic. In the ejection preparation stage, the elastic rope is gradually stretched along with the pulling of the pull rope and the working of the transmission mechanism, and the elastic potential energy is continuously accumulated. When the ejection condition is reached, the elastic potential energy stored by the elastic rope is released, the elastic potential energy is quickly contracted, the energy is converted into the kinetic energy of the ejection ball, and the ejection ball is pushed to be ejected. The material of the elastic cord has a high elastic modulus, good fatigue life and corrosion resistance, such as a high strength rubber or a special elastic alloy wire woven to ensure stable and reliable operation over multiple ejection cycles.

Preferably, a spring force regulator is arranged near the top in the middle of the outer side wall of the elastic rope. The regulating rollers are arranged at the upper end and the lower end of the inner side wall of the spring force regulator, and the regulating roller close to the upper end is driven by a regulating motor arranged at the upper end position in the middle of the right side of the spring force regulator. The position or the rotation state of the upper end regulating rollers is accurately controlled through the regulating motor, the winding angle, the tightness degree and the like of the elastic rope between the regulating rollers are changed, and therefore the accurate regulation of the elastic force of the elastic rope is achieved. The adjusting mode can flexibly adjust the ejection force and speed according to different ejection scenes, the weight of passengers, safety requirements and other factors.
