Flying Movie Theater

technical field

The utility model relates to the field of flying theaters in the amusement industry, in particular to a multi-dimensional servo motion platform for human-computer interaction that highlights the dynamic and spatial sense of the occupant's amusement content.

Background technique

Flying Movie Theater is a new field between traditional movie theater culture and modern large-scale interactive amusement projects. Its important part is to realize the sense of space, dynamics, weightlessness, large viewing angle, looking up, looking down, looking around, multi-degree-of-freedom movement such ride devices and such platforms. Amusement and cultural markets require such devices or platforms to continuously introduce new concepts and technologies, and require flying movie theaters to provide more motion dimensions, more sensitive follow-up of film and television or dynamic models, larger viewing angles and more capacity. Multi-viewer platform. In the flying movie theater market, there is currently no movie theater that integrates the above-mentioned large amount of technical content.

At present, there is no reclining chair-style movie theater looking up, a traditional movie theater with horizontal seats and a wall-mounted flying movie theater. These modes exist simultaneously and dynamically change and transform movie theaters. And interactive amusement projects from looking up at the starry sky to looking down at the distance to overlooking the earth have already raised the demand for this kind of theater. Especially dome theaters need the appearance of this theater machinery.

In addition to its own mechanical safety features, there must be a redundant safety device, and this safety device has a mechanically fixed, non-controllable, and insurmountable position limit. The curve equation specially designed for the rolling mode platform is a long-span cycloid-limited slot and a redundant safety device for limiting the positioning rod, which is not currently available in the flying theater equipment.

In addition to fully matching the film and television and machine models, the movement mode and trajectory of the flying movie theater platform and seats are themselves a hotspot of entertainment interest, so innovation is also required. At present, the Flying Shadow Theater does not have a roll mode such as rim rotation and axis linear motion. The rolling platform is a strong novelty in the flying movie theater industry.

The sports platform and seats of the flying movie theater should try not to block the view of tourists. There should be a wide horizontal field of view and an upward field of view. The obstacles in the left and right field of view of passengers in the current flying movie theater are in front.

Contents of the invention

The utility model mainly aims to solve the above-mentioned technical problems and provide a flying shadow theater for the above-mentioned market demands. The technology of the utility model has six main points: a large-scale interactive amusement dome theater, a rolling platform, a servo hoist wire rope pulling rolling platform mechanism, a rolling platform safety redundant device, a rolling platform The balance component of the rotating platform is a constant speed buffer mechanism when the rolling platform falls back.

A large-scale interactive amusement dome theater with a vertical viewing angle of 270° and a horizontal viewing angle of 180°. The seat has a one-axis servo motion for pitching, and the seat is suspended on the seat suspension hanger of the longitudinal slide. The vertical slide is slidingly connected to the rolling platform, and the vertical slide has a one-axis servo motion for longitudinal translation relative to the rolling platform. The rolling platform has a rolling one-axis servo motion. Seats, longitudinal slides and rolling platforms are controlled by a computerized three-axis motion control system. The three-axis motion control system is integrated with the theater control system, and forms a large-scale interactive amusement facility with film and television, sound and light, audio, dynamic model, and shooting equipment. The platform is divided into two groups, and the two groups move synchronously. There is a passage for personnel between the two groups, and a place for projection equipment at the same time. The occupant can watch and interact with the video when the platform is at any position between the horizontal and vertical and between the horizontal and vertical, and the viewing angle is adjusted by the pitch of the seat. Seats and platforms follow the plot of the film and television during the film and television playing process. The performance control system of the Flying Shadow Theater of the utility model uses a dedicated computer as a clock to uniformly issue time codes to each control computer through the control unit, and the data exchanged in information such as video, lighting, audio, machinery, audience flow, and safety devices are uniform. Contains the event code of the unified programming protocol, which is the so-called synchronous control. Under this kind of synchronous control, all links of the whole theater can be carried out accurately according to the script arrangement.

The utility model relates to a rolling platform, which is used for raising and lowering seat arrays of flying theaters, for interactive amusement platforms, and for bases of human-computer interactive games. The rolling platform is placed on the rack fixed on the frame by meshing the sector gear to realize the rolling of the platform, that is, the rotation of the rim and the horizontal movement of the axis. The position of the rolling platform can be precisely positioned, and the speed, angular acceleration, and torque can be precisely adjusted or followed. This rolling platform has both rotation and up and down and back and forth movement for the viewer (occupant).

The utility model relates to a mechanism in which a rolling platform is pulled up by a servo hoist wire rope and restored to a horizontal posture by its own weight. Make the platform move and stay freely between horizontal and vertical 90°. Since the wire rope is self-adapting to the direction of the pulling force, the mechanism is simplified. The hoist can be placed on the lower part of the rolling platform, which can effectively reduce the noise of the theater.

A rolling platform safety redundancy device. The curve equation defines the movement trajectory of the positioning rod for the long-width trochoidal groove, which plays a redundant insurance role. The safety redundant device does not participate in driving and braking. There is no mechanical contact with the relative moving parts in the safety redundant device no matter whether the equipment is stopped or moving. Only when a fault or accident occurs does the relative moving parts come into contact and limit the movement track.

A rolling platform balance member. When the rolling platform is designed, the weight on both sides of the axis is balanced, and then the counterweight is added to the side without the occupants when the field equipment is debugged, so that the platform can automatically fall back to the horizontal state and only requires a small vertical tension. The balance member should not only meet the motion index but also reach the minimum driving power.

A constant speed buffer mechanism when a rolling platform falls back. The mechanism is composed of multiple gas springs. The gas spring is equipped with an exhaust manual throttle valve. The gas flow control by manual exhaust limits the maximum falling speed of the motion platform and acts as an elastic air cushion when the platform reaches the level. When the platform moves normally, the falling speed is controlled by the servo winch, and the speed is lower than the set speed of the constant speed buffer mechanism, so the constant speed buffer mechanism has no practical effect. The constant-speed buffer mechanism works only when the rolling platform falls back safely due to power failure or mechanical failure, so the constant-speed buffer mechanism is a safety mechanism.

Compared with the modern technology, the utility model has the following advantages:

The structure is simple and the cost is low. The utility model is the simplest in the main body mechanical structure of the existing flying shadow theater, and the manufacturing process of the parts is simple and the precision is not high, there is no precious material, and the purchased parts are all highly versatile devices, which is easy to purchase. The cost is the lowest among similar flying movie theaters with the same crew size.

Routine maintenance and repair costs are low. The utility model is the simplest in the main body mechanical structure of the existing flying shadow theater, and the parts are easy to achieve safety and high life margin. There is no special lubrication system, and the main body mechanism only needs to be coated with grease.

It provides better theater facilities for entertainment creativity, film and television production, and game arrangement. The drag mechanism of the main body moving part of the utility model adopts servo control, and the movement range is large, and the mechanical movement control software is integrated with the whole theater control software, and the mechanical movement is synchronized with the film and television. technical platform or technical support. Relying on the entertainment creativity and film and television production of the utility model, it can better adapt to people's increasing cultural and entertainment needs, and the economic benefits created are also obvious.

It is more suitable for large-scale flying movie theaters with more passengers (audience), which can significantly increase the box office. The mechanical support of the main body of the utility model is balanced in force, and the larger the volume and weight of the parts, the more structural advantages it can show. Compared with the existing structure of the flying shadow theater, it is more suitable for a large flying shadow theater with more audiences.

Obvious low energy consumption. The rolling platform movement of the utility model adopts a gravity balance design, is pulled by a servo winch, and the return journey depends on gravity, so the power of the servo winch is very small, which has the effect of significantly reducing electric energy. The reduction of electric power affects the reduction of the capacity of the entire power supply system, which not only reduces energy consumption but also reduces the cost of infrastructure.

Safer and still keep people comfortable during breakdown evacuation. In similar flying movie theaters, safety considerations are the focus of equipment. But the utility model has two distinctive designs in particular, one is to virtualize a point in the space, scan out the trajectory of the rolling platform during normal operation, construct a limit slot with this trajectory, and establish a redundant safety device. Second, the design of maintaining the comfort of personnel during failure evacuation is currently unavailable in similar flying movie theaters. This design can completely avoid economic claims caused by failure and evacuation caused by the mental and physical discomfort of the audience, which is a potential economic benefit. .

detailed description

Fig. 1 is a side view and a rear view of a flying shadow theater according to an embodiment of the present invention. In order to make the main structure display clear, this figure does not show buildings such as waiting platform stairs irrelevant to the utility model. 01 is a ball screen, and the ball screen is a spherical shape missing 1/4 part. In the dome theater, the audience's pitch angle of view (vertical field of view) is 270°, and the yaw angle of view (horizontal field of view) is 180°. The 1/4 spherical opening of the dome screen is used to arrange the audience's access and projection equipment. The yaw angle of view induces the audience's subjective visual scanning by video and audio, that is, shaking their heads left and right. The tilting angle of view is completed by the compound movement of the rolling platform and the pitching seat, supplemented by the human-machine compound movement of the audience's visual scanning. 02 is the mechanism assembly of the audience array seat platform. The movements of this mechanism assembly are all servo movements, and they can realize speed, speed, acceleration, angular acceleration, comfortable acceleration and deceleration of ergonomics, synchronous control, power-off braking or releasing braking, torque control, etc. This mechanism assembly has a redundant safety mechanism and a comfortable occupant return mechanism in case of failure. This mechanism assembly is equipped with multiple strain detection sensors. When abnormal deformation or abnormal vibration or abnormal noise is detected in the structure, it will report to the computer system and respond according to the level of the plan. The multi-axis motion control software of this mechanism assembly is integrated with the theater performance control system, and shares a clock with the performance system, which is the so-called synchronous control, which realizes the follow-up of the audience (crew) and the film and television. This set of mechanism assembly can be realized not only in the flying movie theater, but also in other large-scale interactive amusement projects. It can not only cooperate with film and television, but also cooperate with machine models, shooting and throwing equipment. This implementation example adopts two rolling platforms, and the two platforms are respectively pulled by their respective servo winches, and the two platforms can either run synchronously, or run differently according to the program arrangement. Each row of seats is driven by a servo motor, controlled by the theater performance system, and follows the plot of the film, either synchronously or asynchronously according to the program. Even if the number of platforms is not 2, but 1 or more than 2, even if the number of seats is more or less than this embodiment, it all belongs to the category of this embodiment.

Fig. 2 is a side view of the rolling platform of the Flying Shadow Theater in a horizontal position according to an embodiment of the utility model. The rolling platform 08 is in a horizontal position, which is not only the boarding and evacuation position of the spectators (passengers) but also the interactive position for watching films or interacting with films and televisions. At this time, the seat 02 can be tilted within a range of 90°, and the audience can watch movies and TV within about 180° between looking up and horizontally. At this time, the longitudinal sliding board 03 can move longitudinally, and the pitching motion of the compound seat can achieve the interactive effect with the film. At this time, the seat can be controlled by the follow-up and can also be released to hang vertically freely by gravity. Especially in the case of power failure, the seats are naturally suspended due to gravity, which is convenient for the audience to evacuate. During the real performance, except for the evacuation and waiting of the audience, the rolling platform does not have much time to be purely horizontal. It has been moving with the plot of the film. When the movement of the platform is small, it can also be called fluctuation. The horizontal position of the rolling platform is completed by its own gravity. Whether the drive is braked or passive, the rolling platform will be stabilized to the horizontal position, and the seat will be stabilized in the vertical position.

Fig. 3 is a side view of the rolling platform 08 of the flying shadow theater in a position between the horizontal and vertical positions according to an embodiment of the present utility model. This position is not only the process of turning the motion platform from the horizontal position to the standard suspended flying movie theater mode, but also the dynamic position of the platform during the projection of the dome theater. It needs to be specially pointed out that this position is a position that often appears during performances. The current model of similar flying movie theaters is that the audience boards in the horizontal position, and the audience in the vertical hanging position watches the film and television. The utility model is different from them, and the rolling platform of the utility model is between 0° and 90°, which are video performances and audience follow-up positions. The rolling platform 08 moves from horizontal to vertical, and the pitching attitude control servo motor of the seat 02 can follow the gravity of the earth to keep the upper body of the passenger upright. It is also possible to control the pitching attitude and release the control of the servo motor, the seat 02 naturally droops, and the upper body of the occupant is basically upright and slightly shakes naturally. It should be pointed out that the control and release of the seat pitch control motor are both control strategies of the theater control system. Since the dome theater plays at a large vertical angle of 270°, the rolling platform 08 rotates between horizontal and vertical within a considerable period of time. At this time, the vertical sliding plate 03 can move vertically, and participate in the audience's follow-up of the film.

Fig. 4 is a side view of the rolling platform of the Flying Shadow Theater in a vertical position according to an embodiment of the utility model. The vertical position of the rolling platform 08 is the main mode of the suspended flying theater. The audience can get the greatest volley and flying feeling in this position. Therefore, the main performance of the dome theater is arranged when the rolling platform 08 is in the vertical position. During this position, the pitch posture of the seat 02 and the longitudinal slide plate 03 change with the plot. Appropriate seat 02 depression angle will enhance the sensory stimulation of the ride to the occupants. The ball screen extends to the vertical line of the rolling platform 08, and the audience has sufficient space to look down at the vertical suspension position. A transparent top cover is installed above the seat, which can prevent the upper occupants from dropping their belongings and causing damage to the lower occupants. The motion effect of the vertical slide board 03 is more prominent when it is vertical, and the overweight and weightless feeling of the audience's accelerated ascent and accelerated fall mainly comes from the motion of the vertical slide board. The up and down of the longitudinal slide combined with the pitch of the seat can simulate the dynamics of an airplane taking off and landing.

Fig. 5 is an overall axonometric view of the flying shadow theater according to the embodiment of the utility model. In order to make the main structure display clear, this figure does not show buildings such as waiting platform stairs irrelevant to the utility model. Seat 02 is installed on the seat hanger of vertically moving slide plate 03. The seat either falls naturally due to gravity or is pitched by a servo motor. The longitudinal slide 03 is connected with the rolling platform 08 by a slide rail and a servo cylinder 05 . The longitudinal slide 03 can move longitudinally relative to the rolling platform 08 . The rolling platform 08 is fixed on the sector gear 11 . The sector gear 11 meshes with the rack gear 10 . The rack 10 is fixed on the frame 01. Rack 01 is fixed with the theater building. The servo hoist 13 is fixed on the theater building, and the rolling platform is pulled by the wire rope 14 to rotate and move to the front of the audience's field of vision. The joint mechanism of the rolling platform 08, the vertical sliding board 03 and the seat 02 has been designed with light weight at the front and heavy weight at the rear, light weight at the top and heavy weight at the bottom. At the same time, it is equipped with a counterweight body 07. When the servo hoist 13 unwinds the wire rope 14, it rolls The platform 08 rotates and moves in the opposite direction to the viewer's field of vision under the gravity drive. At this time, the servo hoist controls the speed of unwinding the rope, thereby controlling the falling speed of the rolling platform. Since the rim of the rolling platform 08 is rotating and the axis is moving in a straight line, the movement track of the audience is rotation + horizontal movement + vertical movement. The cylinder barrel of the gas spring 09 is connected to the frame 01 through a hinge, and the cylinder rod is connected to the motion platform 08 through a hinge. When the equipment is working normally, the gas spring has no effect. Only when there is an accident such as equipment failure or power failure, the servo hoist 13 is unlocked and the wire rope is released. When the falling speed of the rolling platform 08 is greater than the set value, the gas spring 09 acts as a speed limiter. , and play a buffer role when the motion platform is close to the level. It should be pointed out that the wire rope is not loosened completely when the fault occurs, but the servo winch has a brake disc. The brake disc intentionally retains a little friction during equipment debugging. The purpose of this is to prevent the winch drum from being too Stall causes the steel wire rope to be slack, that is to say, when the rolling platform is powered off and falls back, the steel wire rope is always tensioned. The extension length of the cylinder rod of the gas spring 09 reaches the limit when the rolling platform 08 reaches vertical, that is to say, no matter what kind of accident occurs, the gas spring 09 will pull the rolling platform so that it cannot be further tilted when the rolling platform 08 is vertical. turn. The gas spring 09 is also an ergonomic comfort mechanism for replaying the rolling platform 08 in response to accidents. Redundant safety device 12 is fixed on building foundation, and it has a safety slot. The motion platform 08 has a protruding rod running in a safety slot. The center line of the safety groove is the geometric repetition of the motion track of the rolling platform 08. When the equipment is working normally, the redundant safety device 12 has no effect, and the extension rod does not touch the safety slot. Only when there is an accident such as equipment failure or power failure, the extension rod of the rolling platform 08 will contact the safety slot. The safety slot The limit does not allow the movement platform 08 to deviate from the rolling track, so as to achieve the safety effect. The gravity falling back design of the rolling platform 08 has reached the safety purpose, and the redundant safety device 12 belongs to the redundant safety mechanism. The gas spring 09 has achieved the safety purpose of the anti-rolling platform 08 from over-overturning, and the redundant safety device 12 belongs to the over-overover redundant safety mechanism. Counterweight 07 is a multi-piece structure, increasing or decreasing the number of pieces can adjust the weight of the counterweight. This embodiment is 16 rows of seats, which only means that the number of seats is relatively large, and does not mean that the number of rows of seats is a fixed number. Each row of seats is driven by an independent pitching servo, which can be synchronous or asynchronous. For example, if the movie is a rising wave, the seats in the lower row can be raised first, and then the fourth row can be reached.

Fig. 6 is a diagram of the longitudinal slide mechanism of the Flying Shadow Theater according to the embodiment of the present utility model. The longitudinal sliding slide 03 is connected to the rolling platform 08 for longitudinal movement and sliding. Acceleration is a very important element in somatosensory amusement projects. Due to the large mass of the rolling platform, it is difficult to produce large acceleration due to factors such as power, braking force, and mechanical strength. Therefore, the effect of linear acceleration is produced by the longitudinal slide. . Considering factors such as high acceleration, small size, and appropriate elasticity, the longitudinal slide is driven by a servo cylinder. The cylinder barrel of the servo oil cylinder 05 is fixed on the rolling platform 08, and the piston rod of the servo oil cylinder is hingedly connected to the longitudinal slide plate. The oil source circuit of the servo cylinder is equipped with a large-capacity accumulator, which can provide instantaneous large-flow high-pressure hydraulic oil, so the longitudinal sliding plate 03 can realize forward and reverse large-value acceleration according to performance control. Since there is an accumulator in the oil source circuit, the working time of the longitudinal sliding board 03 is less than the resting time in the whole performance cycle due to the limitation of ergonomics tolerance to acceleration, so the power of the oil source of the longitudinal sliding board is very small, It has obvious energy-saving and cost-reducing effects. The servo cylinder is equipped with a displacement sensor and a servo valve, which can precisely control the position, speed and acceleration, and provide a good mechanical platform for the performance script and performance effect.

Fig. 7 is a diagram of a pitching mechanism of a seat in a flying movie theater according to an embodiment of the present invention. In this embodiment, 6 people are arranged in a row to be driven by a servo motor. There will be no objection to the inventiveness of this embodiment if the number of seats in a row is more than 6 or less than 6. The seat 16 of a row of 6 people is suspended on the seat support 17 on the vertically moving slide plate 03. The pitch angle of the seat can be controlled by the servo motor 06, or the servo motor can be unlocked, and the seat can hang freely by gravity. The rows of seats can operate synchronously or asynchronously. Each servo motor is equipped with an encoder, which can precisely control the angle, rotation speed and angular acceleration of the seat, providing a good mechanical platform for the performance script and performance effect. Due to the adoption of servo motor control, the increase and deceleration of the seat can be increased or decreased gradually to make the passengers feel comfortable, or can be increased or decreased rapidly to make the passengers feel stimulated. The asynchronous pitching of each row of seats has the practical significance of performance control. For example, when the explosion shock wave is played at a slow speed, it will gradually impact the occupants from top to bottom.

Fig. 8 is an axonometric view of the redundant safety mechanism of the rolling platform of the Flying Shadow Theater according to the embodiment of the utility model. The limit guide groove structure 12 is fixed on the basic structure of the theater, and the rolling platform metal structure has a safety bar 18 rigidly connected with the rolling platform. The safety bar moves in the limit guide groove. When the equipment is normal, the safety bar is not in contact with the limit guide groove. Only when the equipment breaks down and causes the movement track and posture to change, the safety bar contacts the limit guide groove. A rolling platform has two sets of redundant safety mechanisms with a certain distance between them. The redundant safety mechanism has no power device and has nothing to do with the movement of the rolling platform. From the perspective of equipment operation, it is completely redundant. It just draws a virtual curve at a point in space during normal operation of the equipment. A fixed slot is created equidistantly on both sides, and this slot is used to limit the motion track of the rolling platform in turn, so as to achieve a redundant safety limit. This redundant safety mechanism not only restricts the limit position of the rolling platform, but also restricts the deviation of the entire motion track. redundant mechanism. Specifically, if the tooth shape of the rack and pinion is worn off, the rolling platform still operates normally and the track is correct by relying on the limit guide groove and the safety bar. In fact, the meshing of the rack and pinion and the cooperation of the limit guide groove and the safety bar are both motion mechanisms and safety mechanisms for each other.

Fig. 9 is a planocycloid diagram of the redundant safety mechanism of the rolling platform of the Flying Shadow Theater according to the embodiment of the present invention. The shape of the limiting guide groove is the mathematical transformation of the rack and pinion meshing mathematical curve at the position of the safety bar, and the mathematical equation is a flat epicycloid. This equation can be deduced by mathematical equations, can also be simulated by 3D engineering design software, and can also be obtained by traditional methods of amplifying samples. In order to ensure sufficient rigidity and prevent misoperation during commissioning and maintenance, the limit guide groove has no post-adjustment parts, it is completely rigid, and it must be correct when it is manufactured.

Fig. 10 is a side view of the sector gear meshing with the rack on the rolling platform of the flying theater according to the embodiment of the utility model. In this embodiment, the sector angle of the sector gear is slightly greater than 90°. In order to make the rotation angle of the rolling platform greater or less than 90°, the sector angle of the sector gear will be greater than or less than 90°, no matter it is greater than or less than 90°, the rights of the utility model cannot be changed. In order to improve the safety and service life of the rolling platform, the sector angle modulus of the sector gear is selected as large as possible. This embodiment adopts a standard tooth with a modulus of 50, which is the largest modulus in the GB standard. Because the rolling platform adopts a large modulus tooth shape, the gravity of the normal running rolling platform ensures that the sector gear will not be detached upwards. In addition, the large modulus tooth shape is more conducive to the segmental manufacturing and splicing of sector gears and racks. Whether adopting involute tooth shape or other types of tooth shape, whether adopting standard tooth shape or shifted tooth shape, the rights of the utility model cannot be changed.

Fig. 11 is an axonometric view of the meshing of sector gears and racks on the rolling platform of the Flying Shadow Theater according to an embodiment of the present invention. There is a set of rack and pinion meshing mechanisms on both sides of the rolling platform, and the tension point of the steel wire rope is on the middle surface of the rolling platform, so that the force of the mechanism is balanced. Because the tooth modulus is very large, the gears are lubricated with lubricating grease, and it is enough to wipe off the oil stains by hand and apply new oil regularly. In this embodiment, there are two groups of rolling platforms, including four racks and four sector gears, which are processed together by group technology to ensure consistent size, so that the rolling platforms run smoothly.

Fig. 12 is a cross-sectional view of the rolling safety buffer mechanism of the flying movie theater according to the embodiment of the utility model. Gas spring 09 is made up of cylinder barrel 22 and piston rod 21. The piston rod is hinged to the rolling platform 08 through the hinge assembly 20 . The cylinder barrel is hinged with the frame 01 through the hinge assembly 19 . When the rolling platform is running, the protruding length of the piston rod of the gas spring will change, and the air will enter and exit the cylinder, which will hinder the gas and slow down the moving speed of the rolling platform. 23 is a pneumatic one-way throttle valve. When the piston rod is stretched out, the one-way valve of the pneumatic one-way throttle valve is opened, and the air enters the cylinder smoothly without affecting the running speed of the rolling platform. When the piston rod is retracted, the one-way valve is closed, and the air only remains in the throttle valve channel. The air is hindered by the throttle valve and cannot be exhausted smoothly, which in turn hinders the movement of the rolling platform and achieves the purpose of making the rolling platform run at a limited speed. After the speed limit is set and fixed by the one-way throttle valve in the debugging stage, lock the adjusting handle. When the equipment is working normally, the gas spring has no effect. Only when there is an accident such as equipment failure or power failure, the servo hoist 13 is unlocked and the wire rope is released. When the falling speed of the rolling platform 08 is greater than the set value, the gas spring 09 acts as a speed limiter. , and play a buffer role when the motion platform is close to the level. Without the presence of gas springs, in the event of an accident or failure, the occupants would feel uncomfortable due to the rapid fall of the rolling platform. Since the gas spring limits the maximum falling speed of the rolling platform and acts as an elastic air cushion when the platform reaches the level, the audience (passengers) feel comfortable. The protruding length of the piston rod reaches the maximum when the rolling platform is vertical, and can no longer be extended, so that the maximum rolling angle of the rolling platform is quite controlled, so the gas spring is not only an ergonomic and comfortable mechanism for failure fallback Another security agency.

Fig. 13 is an axonometric view of the rolling safety buffer mechanism of the Flying Shadow Theater according to the embodiment of the utility model. In this embodiment, 4 gas springs are installed on each rolling platform, and 8 gas springs are installed on the two rolling platforms. The first thing to do with more gas springs is to reduce the force of each gas spring in order to disperse the force of the gas springs. Component stress, enhancing the safety of the gas spring is also enhancing the safety of the entire mechanical system. The second is that the gas spring has redundant backup, and the failure of individual gas springs will not affect the performance of the safety buffer mechanism.

Fig. 14 is an axonometric view of a rolling platform counterweight device in a flying movie theater according to an embodiment of the utility model. Rolling platform 08 is designed to balance the weight on both sides of the axis, and then the counterweight 07 is added to the non-occupant side during on-site equipment debugging, so that the platform can automatically fall back to the horizontal state and only requires a small vertical tension. The balance member should not only meet the motion index but also reach the minimum driving power. The counterweight is made of multiple pieces of cast iron. If the cast iron body is added more, the counterweight will be heavier, and the rolling platform will fall faster, but the traction force of the hoist will also increase at the same time. If the counterweight is added less, the traction force of the winch is reduced, but the falling speed of the rolling platform is slow. Therefore, the amount of counterweight is changed according to the requirements of the film for the follow-up of the rolling platform.

Fig. 15 is a side view of the traction mechanism of the rolling platform of the flying movie theater according to the embodiment of the utility model. The movement of the rolling platform 08 depends on the traction of the wire rope 14, which is pulled by the servo winch 13. The sector gear 10 and the rack 11 are the generating mechanism of the rolling platform motion trajectory. The return journey of the rolling platform depends on gravity, and the servo hoist controls the rolling speed of the rolling platform at the speed of the rope. Relying on the balance of the tension of the wire rope and the gravity of the rolling platform, the rolling platform can move and stay freely between the horizontal and vertical 90°. Since the steel wire rope is self-adapting to the direction of the pulling force, the mechanism is simplified. The servo hoist can be gradually accelerated and decelerated according to ergonomic principles to make the audience comfortable, and it can also be accelerated or decelerated instantly to follow the plot of the film. If the wire rope is cut or the winch stalls, the rolling platform will fall back to the horizontal position at a limited speed under the drive of gravity, and the occupants (spectators) will evacuate safely. Due to the use of wire rope traction, the servo hoist can be placed in the basement below the rack, allowing the audience at the lower part of the rolling platform to overlook the space, and at the same time can effectively reduce the winding noise of the hoist wire rope in the theater. The servo motor equipped with the hoist has a brake friction disc. During debugging, the friction disc maintains some friction. When the power is off, the edge line speed of the hoist drum will not be greater than the speed of the wire rope, which means that the wire rope will not slack, or the wire rope will always be taut. The hoist is driven by a servo motor, which can precisely control the position, speed and acceleration of the rolling platform.

Fig. 16 is an axonometric view of the rolling platform traction mechanism of the flying movie theater according to the embodiment of the present utility model. The present embodiment has two groups of rolling platforms, and each rolling platform is respectively pulled by a servo winch. The two platforms can run synchronously, or one can run independently, and the operating mode is managed by the theater performance control system. The two rolling platforms are equipped with alignment sensors, which can be calculated by the computer to adjust the servo hoist to make the two rolling platforms precisely synchronized. The mode of running a rolling platform alone sometimes appears. For example, if there are too few audiences in a certain show, only one rolling platform can be run.
