Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of stage machinery, and in particular relates to an ultra-large load horizontal long-distance traveling auditorium driving device. Background Art
[0002] With the development of the cultural tourism industry, immersive live-action performances are increasingly popular with tourists, even becoming popular check-in spots at many tourist attractions. These shows embody the directors' deep understanding and creativity of Chinese culture, and utilize advanced performance techniques to immerse audiences in the realities of the events. Customized and invented stage machinery is essential for these performances, as it provides the physical foundation for these various artistic expressions and is therefore particularly crucial.
[0003] There are many horizontally running stage equipment in theaters and performing arts shows at home and abroad, such as cart stages, vehicle-mounted turntables, ballet cart stages, ice cart stages, water cart stages, etc. However, due to the limitations of the performance venues, their operating stroke is relatively short, generally not exceeding 40 meters, and the total operating load of the equipment is generally not more than 100 tons. They are mostly driven by rack and pinion relay, rack and pinion trolley push drive, electric friction self-drive, horizontal rigid chain drive, wire rope winch drive, etc.
[0004] Currently, no effective solutions have been proposed for the problems in related technologies.
[0005] Therefore, in order to solve the above problems, the present invention provides an ultra-large load horizontal long-distance walking auditorium driving device. Summary of the Invention
[0006] In order to overcome the above technical problems, the purpose of the present invention is to provide an ultra-large load horizontal long-distance walking auditorium driving device.
[0007] The purpose of the present invention can be achieved through the following technical solutions: A super-large load horizontal long-distance walking audience seat drive equipment includes an audience seat trolley. A power output mechanism, a flexible power transmission mechanism, a load supporting mechanism, a multi-degree-of-freedom mechanical node and an ultra-thin power traction plate are arranged under the audience seat trolley. The power output mechanism is connected to the ultra-thin power traction plate through a flexible power transmission mechanism. The ultra-thin power traction plate is connected to the audience seat trolley. The load supporting mechanism is used to support the audience seat trolley and bear its load. The multi-degree-of-freedom mechanical node is used to eliminate the lateral thrust caused by structural deformation of the audience seat trolley when it is empty and fully loaded.
[0008] Furthermore, there are four sets of power output mechanisms, which are respectively arranged at the four corners of the theater. Two sets of power output mechanisms form a group. The two sets of power output mechanisms are relatively independent and have no mechanical connection. Furthermore, each set of the power output mechanism includes a base, a motor, a brake, a speed reducer, a sprocket box, and a position adjustment component. The motor, the brake, the speed reducer, and the position adjustment component are all installed above the base. The brake is arranged between the motor and the speed reducer. One side of the speed reducer is connected to the sprocket box, and the sprocket box is assembled on the position adjustment component.
[0009] Furthermore, there are two sets of the flexible power transmission mechanisms, which correspond to two groups of power output mechanisms. Furthermore, the flexible power transmission mechanism includes a double-layer bracket, a chain guiding support plate, and a flexible chain. The chain guiding support plate is installed on the double-layer bracket, and the flexible chain is assembled on the chain guiding support plate. The flexible chain is a three-row roller chain and is connected to the sprocket boxes on the power output mechanisms at both the head and the tail.
[0010] Furthermore, the load support mechanism includes a bracket with a steel structure as the main body. A load distribution beam and load-bearing rollers are arranged below the bracket, and the load-bearing rollers are assembled below the bracket. The load-bearing rollers are divided into two rows, and the two rows of load-bearing rollers are connected by the load distribution beam. The load distribution beam cooperates with the multi-degree-of-freedom mechanical joint.
[0011] Furthermore, the multi-degree-of-freedom mechanical joint includes an upper connection component, a horizontal sliding component, a ball head mechanism, a self-lubricating spherical tile mechanism, and a lower connection component. The upper connection component is connected to the bracket. The horizontal sliding component is assembled below the upper connection component by bolts. The ball head mechanism is assembled below the horizontal sliding component by bolts. The ball head mechanism is assembled on the self-lubricating spherical tile mechanism. The lower connection component is assembled below the self-lubricating spherical tile mechanism by bolts, and the lower connection component is assembled on the load distribution beam. <{
[0012] Furthermore, the ultra-thin power traction plate includes a guiding component, a load detection component, a power traction plate, a mobile power transmission component, and a tension rod. The load support mechanism is connected to the flexible power transmission mechanism through the ultra-thin power traction plate. The two ultra-thin power traction plates are connected by the tension rod. A load detection component is connected between the power output mechanism and the flexible chain. The power traction plate and the mobile power transmission component are assembled on the spectator stand trolley.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the power output mechanism drives the flexible power transmission mechanism to move. The flexible power transmission mechanism cooperates with the ultra-thin power traction plate to drive the auditorium trolley to move, realizing the reciprocating operation of the auditorium trolley within the full stroke range. The flexible power transmission mechanism enables the installation position of the power output mechanism to be more flexible, and it can be installed on both sides of the auditorium without affecting the main space of the auditorium and the stage performance.
[0014] 2. In the present invention, the motor is a variable-frequency motor with a large torque ratio. The motor is installed in the foundation pit under the stage floor. After the motor is decelerated by the reducer, the torque is transmitted to the sprocket in the sprocket box, and then it can drive the flexible power transmission mechanism to move.
[0015] 3. In the present invention, the two sets of flexible power transmission mechanisms use three rows of roller chains as the force-bearing structure and are connected to the power output mechanisms at both ends, so that the two sets of power output mechanisms form a closed loop through the flexible chains, and the double-layer brackets assist the flexible chains to achieve a horizontal single-sided length of more than 120 meters for an ultra-long distance.
[0016] 4. In the present invention, the entire set of driving equipment has a total of forty mechanical nodes with degrees of freedom. These mechanical nodes jointly bear the load of about 1000 tons of the auditorium. At the same time, through the design of the internal structure, these nodes have the characteristics of multiple degrees of freedom and also have a position compensation function in the horizontal direction. The mechanical nodes with degrees of freedom are mainly used to eliminate the lateral thrust caused by the structural deformation of the auditorium when it is unloaded and fully loaded.
[0017] 5. In the present invention, the two groups of ultra-thin power traction plates are the key force-bearing units of the driving equipment. The ultra-thin power traction plates pass through the slits in the stage floor, connect the load support mechanism and the flexible power transmission mechanism, and realize the transmission of the driving force of the motor to the auditorium.

[0021] Next, in combination with the accompanying drawings and specific embodiments, the invention will be further described: Please refer to Figures 1 - 12, A driving device for a spectator stand with an ultra-large load for horizontal long-distance walking according to an embodiment of the present invention includes a spectator stand trolley. Below the spectator stand trolley, there are a power output mechanism 1, a flexible power transmission mechanism 2, a load support mechanism 3, a multi-degree-of-freedom mechanical node 4, and an ultra-thin power traction plate 5. The power output mechanism 1 is connected to the ultra-thin power traction plate 5 through the flexible power transmission mechanism 2. The ultra-thin power traction plate 5 is connected to the spectator stand trolley. The load support mechanism 3 is used to support the spectator stand trolley and bear its load. The multi-degree-of-freedom mechanical node 4 is used to eliminate the lateral thrust caused by the structural deformation of the spectator stand trolley when it is unloaded and fully loaded. By driving the flexible power transmission mechanism 2 through the power output mechanism 1, the flexible power transmission mechanism 2 cooperates with the ultra-thin power traction plate 5 to drive the spectator stand trolley to move, realizing the reciprocating operation of the spectator stand trolley within the full stroke range. The flexible power transmission mechanism 2 can make the installation position of the power output mechanism 1 more flexible and can be installed on both sides of the spectator stand without affecting the main space of the spectator stand and the stage performance.
[0022] As Figure 1 , 2 , as shown in Figures 4 and 5, there are four sets of power output mechanisms No. 1, which are respectively arranged at the four corners in the theater. Two sets of power output mechanisms No. 1 are taken as a group, and the two groups of power output mechanisms No. 1 are relatively independent and have no mechanical connection. Each set of power output mechanism No. 1 includes a base 11, a motor 12, a brake 13, a speed reducer 14, a sprocket box 15, and a position adjustment component 16. The motor 12, the brake 13, the speed reducer 14, and the position adjustment component 16 are all installed above the base 11. A brake 13 is arranged between the motor 12 and the speed reducer 14. One side of the speed reducer 14 is connected to the sprocket box 15, and the sprocket box 15 is assembled on the position adjustment component 16. The motor 12 is a variable-frequency motor with a large torque ratio, and the motor 12 is installed in a foundation pit below the stage floor. After the motor 12 is decelerated by the speed reducer 14, the torque is transmitted to the sprocket in the sprocket box 15, and then it can drive the flexible power transmission mechanism 2 to move.
[0023] As Figure 1 , 2 , as shown in Figures 6 and 7, there are two sets of flexible power transmission mechanisms No. II, which correspond to the two groups of power output mechanisms No. 1. The flexible power transmission mechanism 2 includes a double-layer bracket 21, a chain guide plate 22, and a flexible chain 2III. The chain guide plate 22 is installed on the double-layer bracket 21, and the flexible chain 2III is assembled on the chain guide plate 22. The flexible chain 2III is a three-row roller chain and is connected to the sprocket boxes 15 on the power output mechanisms No. 1 at the head and tail. The two sets of flexible power transmission mechanisms No. II use the three-row roller chain as the stress structure and are connected to the power output mechanisms No. 1 at the head and tail, so that the two sets of power output mechanisms No. 1 form a closed loop through the flexible chain II, and the double-layer bracket 21 assists the flexible chain 2III to exceed 120 meters in the horizontal direction of the ultra-long single-side length.
[0024] As Figure 1 、 2 、shown in Figures 3 and 8, the load support mechanism 3 includes a bracket with a steel structure as the main body. A load distribution beam 31 and load-bearing rollers 32 are arranged below the bracket. The load-bearing rollers 32 are assembled below the bracket. The load-bearing rollers 32 are divided into two rows, and the two rows of load-bearing rollers 32 are connected by the load distribution beam 31. The load distribution beam 31 cooperates with the multi-degree-of-freedom mechanical node 4. There are two sets of load support mechanisms 3, each with a length of about 34 meters and a width of about 2.6 meters, with a steel structure as the main body. All the loads are borne by the two rows of load-bearing rollers 32, and the loads of the auditorium are proportionally distributed to the two rows of load-bearing rollers 32.
[0025] As Figure 1 、 2 、shown in Figures 3, 9, and 10, the multi-degree-of-freedom mechanical node 4 includes an upper connection assembly 41, a horizontal sliding assembly 42, a ball head mechanism 43, a self-lubricating spherical tile mechanism 44, and a lower connection assembly 45. The upper connection assembly 41 is connected to the bracket. The horizontal sliding assembly 42 is assembled below the upper connection assembly 41 by bolts. The ball head mechanism 43 is assembled below the horizontal sliding assembly 42 by bolts. The ball head mechanism 43 is assembled on the self-lubricating spherical tile mechanism 44. The lower connection assembly 45 is assembled below the self-lubricating spherical tile mechanism 44 by bolts. The lower connection assembly 45 is assembled on the load distribution beam 31. There are a total of forty degree-of-freedom mechanical nodes 4 in the whole set of driving equipment. These mechanical nodes jointly bear the load of about 1000 tons of the auditorium. At the same time, through the design of the internal structure, these nodes all have the characteristics of multiple degrees of freedom and also have the function of position compensation in the horizontal direction. The degree-of-freedom mechanical node 4 is mainly used to eliminate the lateral thrust caused by the structural deformation of the auditorium when it is unloaded and fully loaded.
[0026] As Figure 1 、 2 、shown in Figures 11 and 12, the ultra-thin power traction plate 5 includes a guiding assembly 51, a load detection assembly 52, a power pulling plate 53, a mobile power transmission assembly 54, and a tension rod 55. The load support mechanism 3 is connected to the flexible power transmission mechanism 2 through the ultra-thin power traction plate 5. The two sets of ultra-thin power traction plates 5 are connected by the tension rod 55. A load detection assembly 52 is connected between the power output mechanism 1 and the flexible chain 23. The power pulling plate 53 and the mobile power transmission assembly 54 are assembled on the auditorium trolley. The two sets of ultra-thin power traction plates 5 are the key force-bearing units of the driving equipment. The ultra-thin power traction plate 5 passes through the slit on the stage floor to connect the load support mechanism 3 with the flexible power transmission mechanism 2, realizing the transmission of the driving force of the motor 12 to the auditorium.
[0027] The working principle of a driving device for a super-large load horizontal long-distance walking auditorium in this invention is as follows: After the motor 12 is decelerated by the speed reducer 14, the torque is transmitted to the sprocket in the sprocket box 15, and then the flexible chain 23 can be driven to move. The two sets of flexible power transmission mechanisms 2 use three rows of roller chains as the force-bearing structure and are connected to the power output mechanisms 1 at both ends, enabling the two sets of power output mechanisms 1 to form a closed loop through the flexible chain 23. Cooperating with the ultra-thin power traction plate 5, the auditorium trolley is driven to move, realizing the reciprocating operation of the auditorium trolley within the full stroke range. The flexible power transmission mechanism 2 can make the installation position of the power output mechanism 1 more flexible and can be installed on both sides of the auditorium without affecting the main space of the auditorium and the stage performance.
