Description

Technical Field

[0001] This utility model relates to the field of orbital flight vehicle technology, specifically a suspended orbital flight vehicle for performances. Background Technology

[0002] The suspended track-mounted aircraft used in performances is a special device tailor-made for stage effects. Operating via a concealed track system on the theater ceiling, it carries actors and props to perform ascents, lateral movements, and rotations. Its core consists of a track support structure, a drive mechanism, and safety locks. Through program control, it achieves precise positioning, satisfying the plot's demands for aerial scenes while ensuring performance safety. In musicals, acrobatic dramas, and other performances, it allows scenes of "flying" and "spacewalking" to realistically unfold, enhancing audience immersion. For example, when depicting mythological stories, actors can be suspended in the air to simulate riding the clouds; when presenting science fiction plots, it can be used with lighting to create an interstellar travel effect. This equipment blends mechanical engineering and artistic creativity, allowing the stage to transcend the limitations of a two-dimensional space, injecting fantasy into performances, and becoming an important element in creating a stunning visual impact in modern stage art.

[0003] For example, patent CN116850612A discloses a spatial flexible cable parallel system for the performance industry, including: a wire harness mechanism, including at least one first wire harness device set on the ground and at least two second wire harness devices set above the ground; a support frame, on which a pulley system is provided; a suspended platform, which is connected to the wire harness mechanism via ropes, the pulley system being connected to the ropes between the suspended platform and the first wire harness device, and the suspended platform being directly connected to the second wire harness device; and a control system, including a control module and multiple automatic balancing devices, which are respectively set on the wire harness mechanism and the suspended platform, and control the wire harness mechanism to raise and lower the ropes according to the flight program preset by the control module, so that the performers suspended below the suspended platform can fly. However, the existing equipment uses a single set of rollers, relying solely on the friction between the rollers and the upper surface of the guide rail for drive. This results in poor stability. When the equipment is running at high speed or traversing curved tracks, the rollers are prone to lateral deviation due to uneven force distribution. In severe cases, this can even lead to the rollers detaching from the guide rail, posing a significant threat to the safety of the performers and the performance flow. Furthermore, the use of a single steel wire rope for suspending the performers carries a high risk factor. If the single steel wire rope wears out and breaks, it will directly cause the performer to fall. At the same time, single-rope suspension is prone to violent swaying due to concentrated force, which not only affects the accuracy of the performance movements but also exacerbates the fatigue wear of the steel wire rope, further reducing the safety redundancy of the equipment operation.

[0004] Therefore, in order to solve such problems, we propose a suspended orbital flying vehicle for performances. Utility Model Content

[0005] The purpose of this invention is to provide a suspended track-mounted flying device for performances, addressing the problems mentioned in the background art. Existing devices, using a single set of rollers and relying solely on friction between the rollers and the upper surface of the guide rail, suffer from poor stability. When the device operates at high speed or traverses curved tracks, the rollers are prone to lateral displacement due to uneven force, potentially even detaching from the guide rail and posing a significant threat to the performers' lives and the performance flow. Furthermore, the use of a single steel cable for suspending performers carries a high risk; wear and breakage of this cable will directly lead to a fall. Additionally, single-rope suspension is prone to violent swaying due to concentrated force, affecting the precision of performance movements and exacerbating fatigue wear on the steel cable, further reducing the safety redundancy of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspended track flying device for performances, comprising an I-beam track, with movable components on both sides of the I-beam track. Each movable component includes a fixed block in a groove on both sides of the I-beam track. Both ends of the inner wall of one side of the fixed block are rotatably connected to a longitudinal moving roller. A side block is fixedly connected to the inner side of the longitudinal moving roller on the inner wall of one side of the fixed block. A transverse moving roller is rotatably connected to the side block. A vertical plate is fixedly connected to the outer side of the bottom of the fixed block. Circular holes are evenly opened at the bottom of the vertical plate. A guide rod is movably connected inside the circular holes. A spring is sleeved on the outer wall of the guide rod. The movable component is fixedly connected to the bottom of the guide rod.

[0007] Furthermore, a limiting block is fixedly connected to the outer end of the inner wall of the I-beam track, and the inner wall of the limiting block is in contact with the inner wall of the longitudinal moving roller.

[0008] Furthermore, the fixing block is threaded with a fixing bolt, the end of which extends into the interior of the upright plate, and the fixing block and the upright plate are fixed together by the fixing bolt thread.

[0009] Furthermore, a connecting plate is fixedly connected to the outer wall of the bottom fixing block of the guide rod, and the connecting plate is U-shaped.

[0010] Furthermore, a U-shaped plate is fixedly connected to the bottom of the connecting plate below the guide rod, and a square groove is opened at the bottom of the U-shaped plate.

[0011] Furthermore, both sides of the top of the groove above the U-shaped plate are fixedly connected to fasteners. A servo motor is fixedly connected to the outer end of the left fastener. A rotating rod is rotatably connected to the fastener, and the rotating rod is fixedly connected to the output end of the servo motor. A rotating roller is fixedly connected to the rotating rod. A hanging rope is threaded around the outer wall of the rotating rod, and an installation component is fixedly connected to the bottom of the rotating rod.

[0012] Furthermore, a drive gear is fixedly connected to the end of the left rotating rod on the U-shaped plate, and a driven gear is fixedly connected to the end of the right rotating rod on the U-shaped plate, with the drive gear and the driven gear meshing together.

[0013] Compared with the prior art, the beneficial effects of this utility model are: a suspended orbital flying vehicle for performances, adopting a novel structural design, the specific details of which are as follows:

[0014] (1) The suspended track flying device used for performances has symmetrical moving components set on both sides of the I-beam track. In each moving component, the longitudinal moving rollers at both ends of the inner wall of the fixed block roll along the length of the track to provide longitudinal guidance for the device. At the same time, the transverse moving rollers are rotatably connected to the side block inside the fixed block, which can effectively limit the transverse deviation of the device. The two together form a two-way guiding structure, which solves the problem of poor stability coefficient caused by the traditional single set of rollers relying solely on friction with the upper surface of the guide rail. It can avoid transverse deviation caused by uneven force on the rollers when running at high speed or passing through curved track sections, thereby preventing the safety hazard of the device leaving the track. In addition, the limiting block at the outer end of the inner wall of the I-beam track fits tightly with the inner wall of the longitudinal moving roller, further limiting and reinforcing the longitudinal movement, reducing the shaking during the operation of the device, and ensuring the accuracy of the performance movements.

[0015] (2) The suspended track flying device used for performance adopts a double suspension rope design. Through the meshing of the active gear at the end of the left rotating rod inside the U-shaped plate and the driven gear at the end of the right rotating rod, the two rotating rods can be driven to rotate synchronously, so that the two suspension ropes can achieve balanced release and force distribution. Compared with the traditional single rope suspension mode, it forms a double safety guarantee: even if one of the suspension ropes is worn or even broken, the other can still bear the load stably, which fundamentally reduces the risk of falling. At the same time, the elastic buffer system composed of the guide rod and the spring can absorb the instantaneous impact force through the extension and deformation of the spring when the device stops suddenly, changes speed or is impacted, effectively alleviating the instantaneous tension of the suspension rope on the actor. This not only avoids the risk of strangulation, but also reduces the fatigue wear of the suspension rope caused by sudden force changes, and extends the service life of the components.

[0016] Furthermore, the fixed block and the upright plate are connected by a threaded bolt for detachable connection. When components such as the longitudinal moving roller and the transverse moving roller in the moving assembly are worn or malfunction, they can be quickly separated by removing the bolt, which greatly simplifies the operation process of component replacement and improves maintenance efficiency. At the same time, the guide rod and the upright plate adopt a movable connection design. The guide rod passes through the round hole at the bottom of the upright plate and can move flexibly. This structure allows the guide rod to drive the U-shaped plate and the suspension rope below to be finely adjusted within a certain angle range. It can be flexibly adapted to the range of motion of the actors and the suspension requirements of props in different performance scenarios, which enhances the scene adaptability of the device.

[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] This utility model provides the following technical solution: a suspended orbital flying vehicle for performances.

[0026] Example 1: A suspended track flying device for performances utilizes symmetrically arranged moving components 2 to enhance the device's stability. A longitudinal moving roller 22 guides the fixed block 21 longitudinally, and a transverse moving roller 231 further guides the fixed block 21 longitudinally. Combined with the elastic action of spring 251 and guide rod 25, this avoids the risk of strangulation injuries to performers on the suspension rope 35 due to sudden device stops. It also prevents the use of a single-roller design, which relies solely on the friction between the roller and the guide rail surface for drive, resulting in poor stability. When the device operates at high speed or traverses curved tracks, the rollers are prone to lateral deviation due to uneven force, potentially even detaching from the guide rail, posing a significant threat to performers' lives and the performance flow.

[0027] like Figure 1 - Figure 5 As shown, a suspended track-mounted flying device for performances includes an I-beam track 1. Movable components 2 are provided on both sides of the I-beam track 1. Each movable component 2 includes a fixing block 21 within a groove on either side of the I-beam track 1. The movable component 2 is precisely engaged with the groove on either side of the I-beam track 1 via the fixing blocks 21. Longitudinal moving rollers 22 are rotatably connected to both ends of the inner wall of one side of the fixing block 21. The longitudinal moving rollers 22 at both ends of the inner wall of the fixing block 21 roll along the inner wall of the track, providing longitudinal movement power along the track direction for the device. Side blocks 2 are fixedly connected to the inner side of the longitudinal moving rollers 22 on one side of the inner wall of the fixing block 21. 3. A transverse moving roller 231 is rotatably connected to the side block 23. The transverse moving roller 231 on the side block 23 is in close contact with the side of the track, effectively limiting lateral displacement and ensuring the accuracy and stability of the overall movement trajectory. A vertical plate 24 is fixedly connected to the outer side of the bottom of the fixed block 21. The bottom of the vertical plate 24 has evenly spaced circular holes, and a guide rod 25 is movably connected inside the circular holes. When the device encounters longitudinal impact forces such as sudden stops, the guide rod 25 slides up and down along the circular holes at the bottom of the vertical plate 24. A spring 251 is sleeved on the outer wall of the guide rod 25. The spring 251 sleeved on the outer wall undergoes elastic deformation, which can quickly absorb impact energy and significantly reduce the impact. The tension fluctuation of the suspension rope 35 ensures suspension safety. The bottom of the guide rod 25 is fixedly connected to the moving component 2. The outer end of the inner wall of the I-beam rail 1 is fixedly connected to the limiting block 11. The limiting block 11 at the outer end of the inner wall of the I-beam rail 1 is in close contact with the inner wall of the longitudinal moving roller 22, forming additional support when the device turns or changes speed, structurally eliminating the risk of the moving component 2 detaching from the rail. The inner wall of the limiting block 11 is in close contact with the inner wall of the longitudinal moving roller 22. The fixing block 21 is threadedly connected to the fixing bolt 241, the end of the fixing bolt 241 extends into the interior of the vertical plate 24, and the fixing block 21 and the vertical plate 24 are fixed together. The guide rod 25 is fixed by bolt 241 with thread. A connecting plate is fixedly connected to the outer wall of the bottom fixing block 21. The connection structure between the U-shaped connecting plate at the bottom of the guide rod 25 and the U-shaped plate 3 is flexible and adjustable. By finely adjusting the position of the guide rod 25, the track installation error can be compensated, ensuring that the hanging components always maintain a horizontal balance and adapting to the precision requirements of diverse performance scenarios. The connecting plate is U-shaped, and its running stability is ensured by a double guide structure. The overall movement trajectory of the moving component 2 is accurate and stable. In addition, the fixing block 21 and the upright plate 24 are fixed by bolt 241 with thread, ensuring the stability of the structural connection.

[0028] Example 2: Unlike Example 1, the meshing of the driving gear and the driven gear enables the two rotating rollers 34 to rotate synchronously, thereby improving the safety of the performers and preventing the use of a single steel wire rope for performer suspension, which has a high risk factor. Once a single steel wire rope wears out and breaks, it will directly cause the performer to fall. At the same time, single rope suspension is prone to violent swinging due to concentrated force, which not only affects the accuracy of the performance movements, but also aggravates the fatigue wear of the steel wire rope, further reducing the safety redundancy of the equipment operation.

[0029] like Figure 6 As shown, a U-shaped plate 3 is fixedly connected to the bottom of the connecting plate below the guide rod 25. A square groove 31 is opened at the bottom of the U-shaped plate 3. Fixing members 32 are fixedly connected to both sides of the top of the groove 31 above the U-shaped plate 3. A servo motor is fixedly connected to the outer end of the left fixing member 32. A rotating rod 33 is rotatably connected to the fixing member 32, and the rotating rod 33 is fixedly connected to the output end of the servo motor. When the servo motor drives the left rotating rod 33 to rotate, the active gear at the end of the left rotating rod 33 meshes with the driven gear at the end of the right rotating rod 33, which can synchronously drive the two rotating rods 33 to rotate precisely. A rotating roller 34 is fixedly connected to the rotating rod 33, and the outer wall of the rotating rod 33 is threaded. There are suspension ropes 35. Since the suspension ropes 35 are wrapped around the outer wall of the rotating roller 34 on the rotating rod 33, the two suspension ropes 35 can be evenly extended and retracted with the synchronous rotation of the rotating rod 33, thereby driving the actor or prop to complete a smooth lifting and lowering action. The bottom of the rotating rod 33 is fixedly connected to the mounting part 36. The end of the left rotating rod 33 on the U-shaped plate 3 is fixedly connected to the drive gear, and the end of the right rotating rod 33 on the U-shaped plate 3 is fixedly connected to the driven gear. The drive gear and the driven gear are meshed and connected. At the same time, the servo motor can precisely control the rotation speed of the rotating rod 33. By adjusting the extension and retraction speed of the suspension ropes 35, the lifting and lowering process is highly matched with the performance rhythm, meeting the precise requirements for lifting and lowering speed in different scenarios.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
