Description

Technical Field

[0001] This utility model relates to the field of movable grandstand technology, and in particular to a movable grandstand moving mechanism. Background Technology

[0002] Portable grandstands, as flexible viewing and activity facilities, are widely used in stadiums, performance venues, and other similar locations. With the diversification of modern venue functions, higher demands are placed on the flexibility and ease of operation of portable grandstands. However, existing portable grandstand technologies have shortcomings in terms of flexibility.

[0003] Currently, the methods for moving grandstands mainly fall into two categories: one is using forklifts. Forklifts have poor maneuverability and turning flexibility, especially in confined spaces or complex site layouts. Their turning and operation are severely limited, making it difficult to meet the rapid transition needs of different venue scenarios. Furthermore, coordinating multiple forklifts simultaneously is challenging, increasing the risk of collisions or operational errors, leading to safety accidents. The other method involves using swivel casters in conjunction with a tow truck. This requires extensive preparation before movement, such as checking the wheel condition and connecting the tow truck, and necessitates significant manpower, reducing work efficiency. While swivel casters offer some steering capability, the synchronization of steering and movement is difficult to guarantee when using a tow truck, resulting in a slow movement process and hindering rapid adjustments to the grandstand's position. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a mobile mechanism for a flexible movable grandstand.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a movable grandstand moving mechanism, including a base, a lifting drive assembly, a lifting frame and at least two drive motors, with movable rollers respectively provided on opposite sides of the base, the drive motors being installed on the base and drivingly connected to the movable rollers, and the lifting drive assembly being installed on the base and connected to the lifting frame.

[0006] Furthermore, auxiliary rollers are provided on opposite sides of the base.

[0007] Furthermore, at least one of the opposite sides of the base is provided with at least two auxiliary rollers, and the auxiliary rollers located on the same side of the base are distributed in the same direction as the movable rollers.

[0008] Furthermore, the base is also provided with at least two first reduction gearboxes, and the drive motor is connected to the moving rollers through the first reduction gearboxes.

[0009] Furthermore, the lifting drive assembly includes a lifting motor, a transmission rod, and a lifting platform connected in sequence. The lifting motor and the lifting platform are mounted on the base, and the output end of the lifting platform is connected to the lifting frame.

[0010] Furthermore, it also includes a second gearbox, through which the lifting motor is connected to the transmission rod.

[0011] Furthermore, the lifting frame can be detachably installed at the output end of the lifting platform.

[0012] Furthermore, the number of lifting platforms is at least two, and at least two of the lifting platforms are connected to the transmission rod.

[0013] Furthermore, the lifting frame is provided with a protective component, which is L-shaped and protrudes from the surface of the lifting frame.

[0014] Furthermore, the protective component is made of rubber.

[0015] The beneficial effects of this utility model are as follows: The movable grandstand moving mechanism provided by this utility model, through the coordinated operation of the base, lifting drive assembly, lifting frame, and at least two drive motors, enables the movable grandstand to move flexibly in different directions while in a lifted state. The base, as the basic support structure, not only provides a stable mounting platform for other components but also enables the grandstand to slide horizontally via its side-mounted rollers. At least two drive motors are respectively mounted on the base and connected to the rollers for transmission. By precisely controlling the motor's direction, the grandstand can move laterally and steer. This dual-motor drive design greatly enhances the flexibility and controllability of the grandstand's movement.

At least two drive motors 4 are respectively mounted on the base 3 and connected to the moving rollers 31. By precisely controlling the direction of the motors, the grandstand can move laterally and in a turning direction. This dual-motor drive design greatly enhances the flexibility and controllability of the grandstand's movement. The combination of the lifting drive assembly and the lifting frame 2 allows the movable grandstand 1 to be smoothly lifted before movement, ensuring that the bottom of the grandstand is completely off the ground, thus avoiding friction and wear during movement. This lifting mechanism not only protects the grandstand and the ground but also allows the moving rollers 31 to roll more smoothly, improving movement efficiency. Overall, through the optimized configuration of each component, the adaptability and mobility of the activity grandstand 1 in various application scenarios have been significantly improved, providing users with an efficient and convenient solution for adjusting the grandstand position.

[0026] Furthermore, auxiliary rollers 32 are provided on opposite sides of the base 3.

[0027] As described above, the auxiliary roller 32 helps to share the load of the main roller, reduce wear, and provide better stability and guidance during movement, ensuring smooth movement.

[0028] Furthermore, at least one of the opposite sides of the base 3 is provided with at least two auxiliary rollers 32, and the auxiliary rollers 32 located on the same side of the base 3 are distributed in the same direction as the movable rollers 31.

[0030] Furthermore, the base 3 is also provided with at least two first reduction gearboxes 41, and the drive motor 4 is connected to the moving roller 31 through the first reduction gearboxes 41.

[0031] As can be seen from the above description, the first reduction gearbox 41 can significantly improve the torque output of the drive motor 4, ensuring that the moving roller 31 can obtain sufficient driving force under various ground conditions, thereby enhancing the reliability of movement.

[0032] Furthermore, the lifting drive assembly includes a lifting motor 5, a transmission rod 6, and a lifting platform 7 connected in sequence. The lifting motor 5 and the lifting platform 7 are mounted on the base 3, and the output end of the lifting platform 7 is connected to the lifting frame 2.

[0033] As described above, the lifting motor 5, transmission rod 6 and lifting platform 7 work together to achieve smooth lifting and lowering, providing stable support and a reliable ground-lifting mechanism for the movement of the movable grandstand 1.

[0034] Furthermore, it also includes a second reduction gearbox 51, through which the lifting motor 5 is connected to the transmission rod 6.

[0035] As described above, the second gearbox 51 further optimizes the torque and speed matching during the lifting process, making the lifting action smoother, reducing structural shaking that may be caused by excessive lifting speed, and improving safety.

[0036] Furthermore, the lifting frame 2 can be detachably installed at the output end of the lifting platform 7.

[0037] As described above, the detachable design enhances the system's flexibility and maintainability, facilitating quick adjustment or replacement of the lifting frame 2 according to different needs of the movable grandstand 1, thus reducing maintenance costs.

[0038] Furthermore, the number of lifting platforms 7 is at least two, and both of the at least two lifting platforms 7 are connected to the transmission rod 6 in a transmission manner.

[0039] As can be seen from the above description, the dual lifting platform 7 design can distribute the lifting force more evenly, avoid structural deformation caused by single-point force, and improve the stability of the lifting process and the durability of the overall structure.

[0040] Furthermore, the lifting frame 2 is provided with a protective component 21, which is used to abut against the movable grandstand 1.

[0041] As described above, the protective component 21 effectively prevents direct collision between the movable grandstand 1 and the lifting frame 2, reduces wear and potential damage risks, and extends the service life of the equipment.

[0042] Furthermore, the protective component 21 is made of rubber.

[0043] As can be seen from the above description, the use of rubber material as protective component 21 not only provides a good cushioning effect, but also has the characteristics of wear resistance and weather resistance, adapting to different usage environments and further improving the protective performance.

[0044] Furthermore, the movable roller 31 is made of PU material.

[0045] As described above, the PU material moving roller 31 maintains good rolling performance while having high wear resistance and grip, adapting to various ground conditions, reducing rolling resistance and noise.
