Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted.

[0042] To enhance the stage atmosphere, modern performances employ increasingly complex cross-track stage scenery systems, including scenery pieces 300, a track system, a mobile platform that operates on the track system to carry the scenery pieces 300 or scenery, and some large-scale display systems. However, conventional stage tracks and platform systems often utilize a single track or multiple parallel tracks, allowing scenery pieces 300 and scenery to move only in one direction. This design limits the efficiency of stage space utilization and prevents the full potential of the three-dimensional space from being fully utilized.

[0043] For example, a single-track system can only achieve forward and backward movement or left and right movement. Although a multi-track parallel arrangement can increase the number of movable tracks, it can only move in the same left and right or forward and backward directions, restricted to the limitations of a two-dimensional plane. This limits the richness of stage art expression and makes it difficult to meet the needs of modern stage art creation.

[0044] In order to solve the above problems, the present invention proposes a scenery system based on a cross track, which aims to expand the utilization efficiency of the stage space and improve the flexibility of the stage art performance form.

[0045] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0046] Example 1

[0047] An embodiment of the present invention provides a cross-track-based scenery system, which is applied to a performance stage. The cross-track-based scenery system includes: a cross-track system 100 and a mobile platform 200; the cross-track system 100 includes: a first track mechanism 110 and a second track mechanism 120 that are perpendicular to each other; the mobile platform 200 includes: multiple wheel groups 210; the mobile platform 200 is rollingly connected to the track of the cross-track system 100 through the wheel groups 210.

[0048] Specifically, the cross-track-based scenery system consists of multiple sets of horizontal and vertical tracks, forming a cross-shaped layout. The tracks are constructed of high-strength steel rails with excellent wear resistance and stability. The track system layout can be flexibly adjusted according to specific stage design requirements, allowing for the creation of a variety of complex scenery effects. In some preferred embodiments of the present invention, a double track can be used with a track spacing of 2.6 to 2.8 meters to accommodate scenery and props of different sizes.

[0049] Each mobile platform 200 includes a base plate, which is also a load-bearing platform 220. The base plate is usually made of high-strength aluminum alloy or steel plate to ensure sufficient rigidity and strength. Each mobile platform 200 is provided with a plurality of wheel sets 210. The wheel sets 210 are connected to the platform base plate through a slewing support structure 230 and can be adjusted within a certain steering angle so that the platform can adapt to different moving directions. In some preferred embodiments of the present invention, each wheel set 210 consists of two pairs of wheels, and the inner edge of the wheel protrudes 3 to 5 cm to ensure good contact with the track. The outer diameter width of the wheel is consistent with the track width, with a radius of 25 to 35 cm, and the horizontal distance between the two wheel axles is 60 to 80 cm to ensure that the platform remains stable when passing through the cross-track gap. The wheel axle diameter is 50 to 70 mm to ensure sufficient strength, and the outer edge width of the wheel is 10 to 15 cm to ensure good contact with the track.

[0050] Multiple sets of horizontal and vertical tracks are arranged on the stage, and multiple mobile platforms 200 are deployed on each set of tracks. These platforms can move individually or in combination to form a variety of complex scenery effects. The mobile platforms 200 can be flexibly arranged as needed, for example, see Figure 4 The diagram shows a combination of scenery and a supporting platform, according to an embodiment of the present invention. Scenery 300 is deployed on the horizontal track, while props are deployed on the vertical track, creating a layered or crisscrossing, undulating scenery effect. Because the platform and wheel assembly 210 are connected via a slewing support structure 230, they can move on different tracks, creating different orientations for scenery 300 and enhancing the expressiveness of scenery 300 on stage.

[0051] The cross-track-based scenery system provides both horizontal and vertical paths for the mobile platform 200 through a crisscross track system. Compared to traditional single-direction track arrangements, this significantly expands the scope of stage space utilization. The wheel sets 210 at each end of the mobile platform 200 are connected to the platform via a slewing support structure 230, allowing for steering adjustment within a certain angle, enabling the platform to move at any angle. By deploying multiple sets of horizontal and vertical tracks on the stage, placing multiple mobile platforms 200 on each set of tracks, or even deploying large platforms spanning multiple tracks, more complex stage scenery designs can be achieved.

[0052] For example, the cross track system 100 is provided with one or more cross tracks on a large stage. Figure 1 The embodiment of the present invention provides a top view of a cross track and Figure 2 The embodiment of the present invention provides a schematic diagram of a cross track combination, wherein the track system includes a horizontal track and a vertical track. Figure 2 Among them, track 1# is the first track mechanism 110, and track 6# is the second track mechanism 120. The track in each direction is composed of two parallel steel rails with a track spacing of 2.6 to 2.8 meters. A 15cm gap is left at the cross-intersection. Compared with the traditional single-track or multi-track parallel arrangement, this cross-track design greatly expands the space available for activities on the stage. Not only can it move forward and backward, but it can also move left and right, and even complete complex turning movements. The track is made of high-strength steel with good wear resistance and stability, and can carry heavier scenery and props. The layout of the track system can be adjusted according to the requirements of the stage design, and the horizontal and vertical tracks can be flexibly combined to form a variety of scenery effects.

[0053] See also Figure 3The diagram shows the position of a wheel assembly and slewing support structure provided by an embodiment of the present invention. A wheel assembly 210 is provided at each end of the mobile platform 200, connected to the platform base via a supporting frame 240 and a slewing support structure 230. The slewing support structure 230 is typically a low-profile, large-radius nested bearing assembly, ensuring overall structural stability. The slewing support structure 230 supports the wheel assembly 210 in steering within a certain angle, allowing the platform to adapt to different movement directions. Each wheel assembly 210 on each platform consists of two pairs of wheels placed at either end of an axle, with the two axles arranged parallel to each other. The inner edge of each wheel protrudes 3 to 5 cm. The horizontal distance between the two axles is slightly larger than the outer diameter of the wheels, at 60 to 80 cm. The advantage of this wheel assembly 210 design is that it ensures the platform remains stable during travel. Because each wheel assembly 210 at each end of the platform always has a wheel on one axle in contact with the track, it maintains relatively stable movement even when passing through gaps in the intersecting tracks.

[0054] Wheelset 210 is guided by guide wheels, installed in front and behind the main wheels. The guide wheels have a diameter of 15 to 20 cm to ensure stable passage at intersections. A photoelectric or mechanical positioning system is installed to monitor the platform position in real time to ensure automatic adjustment of the direction of wheelset 210 at intersections.

[0055] Furthermore, in some preferred embodiments of the present invention, multiple sets of horizontal and vertical tracks can be arranged on the stage, with multiple mobile platforms deployed on the horizontal tracks and multiple mobile platforms deployed on the vertical tracks; each mobile platform can be equipped with a different large-scale scenery piece 300. Another deployment method is to deploy one end of each platform on the horizontal track and one end on the vertical track. Because the platform and the wheel assembly 210 are connected by a steering support, the wheel assembly 210 at each end of the platform can form different orientations for the scenery piece 300 when it moves on the two tracks. This serves as a new type of scenery arrangement and increases the expressiveness of the scenery piece 300 on the stage.

[0056] This multi-carriage system can further improve the efficiency of stage space utilization and realize more complex scenery designs. For example, it can realize layered or crisscrossing scenery effects, which are impossible to achieve with previous single-track or parallel track systems.

[0057] The cross track system 100 and the mobile platform work together to realize various flexible movements of stage props and scenery.

[0058] Firstly, the cross-track system provides both horizontal and vertical paths for the mobile stage, which greatly expands the scope of stage space utilization compared to the traditional single-direction track arrangement.

[0059] Secondly, the wheels 210 at each end of the mobile platform are connected to the platform via a slewing support structure 230, allowing for steerable adjustment within a certain range. This allows the platform to be positioned on both the horizontal and vertical tracks as needed, enabling the platform to move at any desired angle. The slewing support structure 230 is constructed from high-strength aluminum alloy or steel, offering excellent rigidity and shock absorption. Connected to the platform's baseplate via an adjustable steering mechanism, it allows for a certain degree of rotation to accommodate different track orientations.

[0060] A spring suspension system is used to cushion vibrations caused by uneven tracks. The spring stiffness is 1000-2000N / mm, ensuring stability under varying loads.

[0061] Furthermore, by deploying multiple sets of horizontal and vertical tracks on the stage and placing multiple mobile platforms on each set of tracks, or even deploying large platforms spanning multiple tracks, more complex stage set designs can be achieved.

[0062] For example, it is possible to create overlapping or staggered scenery effects, which are impossible with traditional single-directional track systems. The mobile stage can move freely within the crisscrossing track network, making full use of the three-dimensional space of the stage and greatly enhancing the flexibility and richness of theatrical performance.

[0063] Furthermore, on a larger stage, multiple sets of crisscross track systems 100 are deployed, along with multiple large carriages spanning multiple tracks. The wheels 210 of these large carriages are placed on different tracks. By controlling the movement and steering of the wheels 210, more complex scenery designs can be achieved. For example, multi-layered scenery effects can be created, or different tracks can be used to move in different directions, increasing the expressiveness of the stage.

[0064] The present invention provides a cross-track-based scenery system, which is applied to a stage, comprising: a cross-track system 100 and a mobile platform 200; the cross-track system 100 comprises: a first track mechanism 110 and a second track mechanism 120 that are perpendicular to each other; the mobile platform 200 comprises: a plurality of wheel sets 210; the mobile platform 200 is connected to the track of the cross-track system 100 through the wheel sets 210 in a rolling manner; by setting up mutually interlaced track mechanisms, the movement direction of the mobile platform 200 on the stage is increased, the existing two-dimensional flat scenery is upgraded to a three-dimensional scenery, enriching the artistic expression form of the stage and providing more possibilities for modern stage art creation. This cross-track-based scenery system, through its unique cross-track design and multifunctional mobile platform 200, not only improves the efficiency of stage space utilization, but also greatly enriches the performance techniques and visual effects of stage art. In addition, through the sophisticated wheel set 210 design and efficient track layout, the efficiency and stability of the system are guaranteed, enabling modern stage performances to reach new heights.

[0065] Furthermore, in some preferred embodiments of the present invention, the first track mechanism 110 and the second track mechanism 120 both include: two mutually parallel first rails and second rails; the wheel set 210 includes: at least one pair of parallel first wheels and second wheels; the distance from the outer side of the first rail to the outer side of the second rail is equal to the distance from the outer side of the first wheel to the outer side of the second wheel.

[0066] For details, see Figure 5 The embodiment of the present invention provides a schematic diagram of a track plan, in which the width and thickness of each track are designed according to the expected load and the specifications of the platform. The spacing between the tracks (i.e., the distance from the outside of the first track to the outside of the second track) is a key parameter, which must be exactly equal to the distance from the outside of the first wheel to the outside of the second wheel on the mobile platform 200. Such a design ensures maximum stability and minimum swing of the platform during movement. The tracks are usually made of high-strength steel to withstand repeated use and heavy loads. The steel undergoes special treatments, such as quenching or coating, to improve its wear resistance and corrosion resistance.

[0067] The design of wheelset 210 ensures that the distance from the outside of the first wheel to the outside of the second wheel exactly matches the distance from the outside of the first rail to the outside of the second rail. This matching is crucial because it prevents any potential wobbling or derailment of the platform during use. Each wheelset 210 includes at least a pair of parallel first and second wheels. These wheels are typically made of highly wear-resistant materials, such as forged steel or alloy steel, and may be hardened for increased durability.

[0068] The design of this track and wheel assembly 210 system allows stage technicians to quickly adjust or replace scenery according to different performance requirements. The system's modularity makes maintenance and upgrades easier. Through precise calculation and design of the fit between the wheels and tracks, operational safety is greatly improved, reducing the risk of accidents caused by equipment failure. Through the carefully designed first and second track mechanisms 110, 120, and the matching wheel assembly 210, this cross-track-based scenery system provides unparalleled stability, safety, and the ability to adapt to a variety of stage settings. This not only enhances the visual effects of stage performances, but also improves operational efficiency and reliability.

[0069] Furthermore, in some preferred embodiments of the present invention, the first wheel and the second wheel are both provided with wheel rims on the inner sides of the wheels along the circumference of the wheels.

[0070] Specifically, the wheel flange guides the wheels along the track, reducing the risk of wheel derailment and ensuring smoother train travel. The wheel flange also limits lateral wheel displacement, preventing the wheels from straying from the track during travel and improving train safety. On curved tracks, the wheel flange abuts against the inner side of the outer rail, guiding the train along the curve and providing guidance. The presence of the wheel flange ensures more uniform contact between the wheel and the track, reducing wear on both wheels and the track. This improves the train's adaptability to different routes, including straight and curved tracks.

[0071] Furthermore, in some preferred embodiments of the present invention, a gap is provided at the intersection of the vehicle rail of the first track and the vehicle rail of the second track; the width of the gap is greater than the thickness of the wheel rim.

[0072] Specifically, the presence of the gap eliminates the need for the wheels to closely contact the track when passing through the intersection, reducing wear on both wheels and tracks. The gap also reduces friction between the wheels and tracks, thereby reducing noise generated during train operation. The gap design prevents wheels from getting stuck when passing through the intersection, thereby improving train safety. The width of the gap is greater than the thickness of the wheel rim, allowing the wheels to smoothly pass through the gap and transition between different tracks.

[0073] The gap at the track intersection adopts an arc transition design to reduce the vibration when the wheel set 210 passes. A sliding plate is installed at the track intersection, and the height is adjusted by a spring or hydraulic system to ensure that the wheels pass smoothly.

[0074] In addition, the gap can adapt to the changes in track size caused by temperature changes, ensuring the normal operation of the train under different temperature conditions. Overall, this design improves the flexibility, safety and adaptability of the train by providing gaps at the track junctions, while reducing wear and noise.

[0075] Furthermore, in some preferred embodiments of the present invention, the wheels include two pairs of first wheels and second wheels arranged in parallel.

[0076] Specifically, two pairs of parallel wheels can provide a larger contact area, increase the stability of the train, and reduce shaking and tilting. The four-wheel structure can disperse the weight of the train, reduce the load on a single wheel, and reduce the pressure on the track. More wheels are in contact with the track, increasing grip, improving the traction and braking force of the train. Two pairs of parallel wheels can better adapt to the unevenness of the track, making the train run more smoothly. If one of the wheels fails, the other wheels can still keep the train running stably, improving the safety of the train. In general, this design improves the stability, safety and driving smoothness of the train by adopting two pairs of parallel first wheels and second wheels, while dispersing pressure and increasing grip.

[0077] Furthermore, in some preferred embodiments of the present invention, the mobile platform 200 also includes: a slewing support structure 230 and a carrying platform 220; the wheel group 210 is connected to the carrying platform 220 through the slewing support structure 230, and the wheel group 210 can be relative to the carrying platform 220 through the slewing support structure 230.

[0078] Specifically, the slewing support structure 230 allows the wheel set 210 to rotate relative to the carrying platform 220, thereby achieving flexible steering of the mobile platform 200 and meeting the movement requirements in different directions. For example, when the mobile platform 200 wants to move from one track to a track perpendicular to it, when the wheel set 210 moves to the intersection of the two sets of tracks, the slewing support structure 230 rotates the direction of the wheel set 210 so that the wheel set 210 rotates 90° relative to the original position on the horizontal plane, and then it can move on the new track. The slewing support structure 230 usually uses rolling elements (such as balls or rollers) to reduce the friction between the wheel set 210 and the carrying platform 220 and improve the smoothness of rotation. The slewing support structure 230 can withstand large axial and radial loads to ensure the stability of the mobile platform 200 under heavy load conditions. Through the rotation function of the slewing support structure 230, the mobile platform 200 can adjust the direction of travel without changing the direction of the vehicle body, thereby improving work efficiency.

[0079] Furthermore, the slewing support structure 230 is typically designed to facilitate maintenance and replacement, improving the maintainability of the equipment. The slewing support structure 230 is compact, space-saving, and makes the overall dimensions of the mobile platform 200 more reasonable. The use of the slewing support structure 230 to connect the wheels 210 and the load-bearing platform 220 and enable the wheels 210 to rotate relative to the load-bearing platform 220 improves the steering flexibility, operating efficiency, and adaptability of the mobile platform 200, while also reducing friction, increasing load-bearing capacity, and facilitating maintenance.

[0080] Furthermore, in some preferred embodiments of the present invention, the slewing support structure 230 includes: a first ring and a second ring that are mutually socketed and can rotate relative to each other; the first ring is connected to the wheel set 210; and the second ring is connected to the supporting platform 220.

[0081] Specifically, the interlocking structure of the first ring and the second ring enables relative rotation between the two, thereby realizing the rotation of the wheel set 210 relative to the load-bearing platform 220 and providing flexible steering capabilities. The slewing support structure 230 can withstand large axial and radial loads, ensuring the stability of the mobile platform 200 under heavy load conditions. Rolling elements (such as balls or rollers) are usually used between the first ring and the second ring to reduce friction and improve the smoothness of rotation. The interlocking first and second rings are compact in design, saving space, making the overall size of the mobile platform 200 more reasonable. Due to the relative rotation of the first and second rings, the slewing support structure 230 is usually designed to be easy to maintain and replace, improving the maintainability of the equipment. Through the rotation function of the slewing support structure 230, the mobile platform 200 can adjust the direction of travel without changing the direction of the vehicle body, thereby improving work efficiency. The rotation capability of the slewing support structure 230 enables the mobile platform 200 to better adapt to complex working environments, such as narrow spaces or changing terrain.

[0082] Furthermore, in some preferred embodiments of the present invention, the mobile platform 200 also includes: a rotating motor and a reduction mechanism; the rotating motor is connected to the slewing support structure 230 through the reduction mechanism, and the rotating motor is used to drive the slewing support structure 230 to rotate so that the wheel group 210 rotates relative to the supporting platform 220.

[0083] Specifically, through the drive of the rotating motor, the automatic rotation control of the wheel set 210 relative to the supporting platform 220 can be achieved, thereby improving the convenience and accuracy of operation. The reduction mechanism can reduce the output speed of the rotating motor, provide a speed more suitable for the rotation of the slewing support structure 230, and ensure the smoothness of the rotation process. The reduction mechanism can also increase the output torque of the rotating motor to ensure that the slewing support structure 230 can still rotate smoothly when bearing heavy loads. By precisely controlling the rotation angle and speed of the wheel set 210, work efficiency can be improved, especially in situations where the direction of travel needs to be adjusted frequently. This design enables the mobile platform 200 to better adapt to complex working environments, such as narrow spaces or changing terrain. By precisely controlling the working state of the rotating motor, unnecessary energy waste can be avoided, achieving the effect of energy saving and emission reduction. The automated control system can reduce human error and improve the safety of the mobile platform 200.

[0084] In general, this design uses a rotating motor and a reduction mechanism to drive the slewing support structure 230 to rotate, thereby realizing automatic rotation control of the wheel group 210 relative to the supporting platform 220, improving operational convenience, accuracy, work efficiency and safety, while enhancing the adaptability and energy-saving and emission reduction effects of the mobile platform 200.

[0085] Furthermore, in some preferred embodiments of the present invention, the mobile platform 200 also includes: a linear module; the guide rail of the linear module is connected to the wheel set 210; wherein, the extension direction of the guide rail of the linear module is parallel to the axial direction of the wheel of the wheel set 210; the slider of the linear module is connected to the supporting platform 220; the linear module is used to drive the supporting platform 220 to move along the axial direction of the wheel of the wheel set 210.

[0086] Specifically, the linear module can provide high-precision linear motion, allowing the carrier platform 220 to move accurately along the axial direction of the wheel, meeting the requirements of precise positioning. The cooperation between the guide rail and the slider of the linear module can ensure the stability of the carrier platform 220 during movement and reduce shaking and vibration. The linear module adopts an efficient transmission method, such as a ball screw or a synchronous belt, which can convert rotational motion into linear motion and improve transmission efficiency. The linear module can select different strokes and speeds according to actual needs to adapt to the usage requirements of different scenarios. The linear module structure is relatively simple and easy to install and maintain. Since the guide rail of the linear module is connected to the wheel group 210, and the extension direction of the guide rail is parallel to the axial direction of the wheel, the overall design is compact and space-saving. The linear module can make the carrier platform 220 swing left and right relative to the forward direction of the wheel group 210, allowing more creative designs at the bends of the track.

[0087] The present invention provides a cross-track-based scenery system that significantly improves the efficiency of stage space utilization and enhances the flexibility and richness of stage art performances. By arranging multiple sets of horizontal and vertical tracks on the stage and deploying multiple mobile platforms on each set of tracks, complex scenery designs can be achieved, meeting the needs of modern stage art creation.
