Description

Technical Field

[0001] This invention relates to the field of stage hoisting equipment technology, specifically to an independent feedback high-precision stage hoisting system. Background Technology

[0002] Stage performances require many props, among which stage rigging is a common one. Stage rigging is used in theaters, auditoriums, clubs, studios, multi-purpose halls, and stadiums to suspend lighting fixtures or backdrops. It belongs to the category of suspension machinery and is one of the important stage machinery in modern theaters. Stage rigging is mainly used to suspend various backdrops or curtains as horizontal bars or panels. It usually runs through the entire stage and can be raised and lowered by a hoisting device. Normally, it is suspended above the stage in a position not visible to the audience. It is only lowered to secure the suspended objects when the stage is being set up. In order to improve the strength and hoisting accuracy of stage rigging, an independent feedback high-precision stage rigging system has been designed to meet the needs of higher standards or higher specifications of stage performances.

[0003] Traditional stage rigging systems, in practical use, can generally only be adjusted vertically via a hoisting device, lacking the ability to adjust the horizontal plane of the suspended objects. For items requiring horizontal adjustment, such as spotlights or curtains, multiple horizontal stage rigging rods must be arranged in the plane, making the entire system extremely complex. Modern stage rigging designs, to accommodate horizontal adjustments, often incorporate multiple vertical side rods on either side of the main rigging plate. However, these side rods often have poor adjustability, typically connected vertically to the main rigging plate with bolts and screws, preventing angle rotation. This not only increases the footprint of the entire stage rigging system, making setup more difficult, but also hinders storage, requiring disassembly and reinstallation for each setup, further increasing setup time.

[0004] Therefore, it is necessary to invent an independent feedback high-precision stage rigging system to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide an independent feedback high-precision stage rigging system. This system solves the problem that the side rigging added in existing technologies often has poor adjustability. It is generally connected vertically to the main rigging plate by bolts and screws, which cannot be rotated. This not only increases the floor space of the entire stage rigging system, making actual setup more difficult, but also makes it inconvenient to store. Each setup requires disassembly and reinstallation, further increasing setup time.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An independent feedback high-precision stage rigging system includes a suspended plate detachably connected to a suspension winch device and multiple sliding plates slidably fitted on both sides of the suspended plate. Each sliding plate can be locked at any sliding position. Side suspension rods are rotatably connected to both ends of each sliding plate, and these side suspension rods can be locked at any rotation angle. A movable suspension rod is detachably and rotatably abutted against the middle of the bottom end of each side suspension rod, and this movable suspension rod can be locked at any rotation angle. Multiple first threaded mounting holes are provided inside each side suspension rod, and multiple second threaded mounting holes are provided inside each movable suspension rod. Slide rails are detachably connected to symmetrical positions on the top of each sliding plate. Slide rails are slidably connected to slide blocks, and a pull rod is rotatably connected to the top of each slide block. The other end of the pull rod is rotatably positioned with respect to the end of the side suspension rod furthest from the sliding plate.

[0008] When the slide block is located in the middle section of the slide rail, the side suspension rod is perpendicular to the suspension plate; when the slide block slides to both ends of the slide rail, the side suspension rod is parallel to the suspension plate.

[0009] As a preferred embodiment of the present invention, the hanging plate has side movable grooves with one side open on both sides, and the center of the sliding plate has a first positioning stud that can slide laterally along the side movable groove. Both ends of the first positioning stud are threaded with a first nut that can lock the sliding plate and the hanging plate.

[0010] As a preferred embodiment of the present invention, both ends of the slide plate are connected to side brackets, and the side hanger is rotatably connected to the side brackets by a second positioning stud, and both ends of the second positioning stud are threaded with a second nut that can lock the rotation angle of the side bracket and the side hanger.

[0011] As a preferred embodiment of the present invention, the top center of the movable rod is connected to a third positioning stud that rotates through the side rod and extends above the side rod, and the portion of the third positioning stud above the side rod is threaded with a third nut that can lock the rotation angle between the movable rod and the side rod.

[0012] In a preferred embodiment of the present invention, a fourth positioning stud is connected to the top of the slide block, the pull rod is rotatably sleeved on the fourth positioning stud, and the portion of the fourth positioning stud above the pull rod is threaded onto a fourth nut that can lock the rotation angle between the pull rod and the slide block. A locking pin is connected to the bottom surface of the end of the pull rod away from the slide block, and the locking pin is rotatably inserted through the end of the side hanger away from the slide plate. A fifth nut is threaded onto the portion of the locking pin below the side hanger.

[0013] As a preferred embodiment of the present invention, baffles are connected to both ends of the slide rail;

[0014] When the slide block slides to both ends of the slide rail and abuts against the baffle, the side suspension rod and the suspension plate are parallel.

[0015] As a preferred embodiment of the present invention, mounting studs are provided at symmetrical positions on the top of the slide plate centered on the slide rail, and side mounting plates that can be detachably sleeved on the mounting studs are connected to both sides of the slide rail. The portion of the mounting stud located above the side mounting plate is threaded with a sixth nut.

[0016] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0017] In this invention, the connection position between the side hangers and the hanging plate is adjusted by a sliding plate, thereby adjusting the lateral distance between multiple side hangers located on the same side of the hanging plate. This allows for flexible adjustment during actual layout. Simultaneously, by driving the sliding block to change its position on the slide rail, the side hangers and the sliding plate rotate, allowing the side hangers to be adjusted at different angles from parallel to perpendicular to the hanging plate. This facilitates flexible adjustment of the connection angle between the side hangers and the hanging plate during actual layout, and allows for the placement of hanging objects in different horizontal directions within the plane of the side hangers. Furthermore, by adding a movable hanger below the side hangers that can rotate at any angle, the use of the first and second threaded mounting holes further increases the number of horizontal mounting positions for hanging objects, improving the adjustability during actual layout. When not in use, the side hangers and the hanging plate can be paralleled by sliding the sliding block to the end of the slide rail, reducing the shared horizontal footprint of the hanging plate and multiple side hangers without disassembly, thus simplifying actual layout while facilitating storage.

[0025] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0026] This invention provides, for example Figure 1-5 The illustrated independent feedback high-precision stage rigging system includes a suspension plate 1 detachably connected to a suspension winch device and multiple sliding plates 3 slidably fitted on both sides of the suspension plate 1. The sliding plates 3 can be locked at any sliding position. Side suspension rods 7 are rotatably connected to both ends of the sliding plates 3, and the side suspension rods 7 can be locked at any rotation angle. A movable suspension rod 9 is detachably and rotatably abutted against the middle of the bottom end of the side suspension rod 7, and the movable suspension rod 9 can be locked at any rotation angle. Multiple first threaded mounting holes 10 are provided inside the side suspension rods 7, and multiple second threaded mounting holes 10 are provided inside the movable suspension rod 9. The mounting hole 25 and the top of the slide plate 3 are symmetrically connected to the slide rail 11. The slide rail 11 is slidably connected to the slide seat 12. The top of the slide seat 12 is rotatably connected to the pull rod 14. The other end of the pull rod 14 is rotatably set to the end of the side hanging rod 7 away from the slide plate 3. The suspension winch device is detachably connected to the hanging plate 1 to realize the longitudinal lifting and lowering adjustment of the device. The object to be suspended can be detachably installed between the side hanging rod 7 and the movable hanging rod 9 through the first threaded mounting hole 10 and the second threaded mounting hole 25 respectively, which completes the disassembly and installation of the object to be suspended from the hanging plate 1.

[0027] When the slide block 12 is located in the middle section of the slide rail 11, the side hanger 7 is perpendicular to the hanger plate 1. When the slide block 12 slides to both ends of the slide rail 11, the side hanger 7 is parallel to the hanger plate 1.

[0028] Both sides of the hanging plate 1 are provided with side movable grooves 2, one of which is open. The center of the sliding plate 3 is provided with a first positioning stud 4 that can slide laterally along the side movable groove 2. Both ends of the first positioning stud 4 are threaded with a first nut 17 that can lock the sliding plate 3 and the hanging plate 1. During the process of the sliding plate 3 sliding laterally along the hanging plate 1, the first positioning stud 4 slides laterally along the side movable groove 2 to limit the movement. At the same time, the sliding plate 3 and the hanging plate 1 can be locked by rotating the first nut 17.

[0029] Both ends of the slide plate 3 are connected to side brackets 5. The side hanger 7 is rotatably connected to the side bracket 5 by a second positioning stud 6. Both ends of the second positioning stud 6 are threaded with a second nut 18 that can lock the rotation angle between the side bracket 5 and the side hanger 7. The rotatable connection between the side hanger 7 and the side bracket 5 realizes the adjustment of the angle position between the side hanger 7 and the hanging plate 1. Furthermore, by rotating the second nut 18, the position of the side hanger 7 can be locked at any rotation angle.

[0030] The top center of the movable rod 9 is connected to a third positioning stud 8 that rotates through the side rod 7 and extends above the side rod 7. The portion of the third positioning stud 8 above the side rod 7 is threaded with a third nut 19 that can lock the rotation angle between the movable rod 9 and the side rod 7. The third positioning stud 8 rotates through the side rod 7 to complete the rotation of the movable rod 9, and the movable rod 9 can be locked at any rotation angle by rotating the third nut 19.

[0031] The top of the slide block 12 is connected to a fourth positioning stud 13. The pull rod 14 is rotatably sleeved on the fourth positioning stud 13. The part of the fourth positioning stud 13 above the pull rod 14 is threaded onto a fourth nut 20 that can lock the rotation angle between the pull rod 14 and the slide block 12. The bottom surface of the end of the pull rod 14 away from the slide block 12 is connected to a locking pin 15. The locking pin 15 is rotatably inserted through the end of the side hanger 7 away from the slide plate 3. The part of the locking pin 15 below the side hanger 7 is threaded onto a fifth nut 21. The fifth nut 21 is mainly used to lock the sleeve position of the locking pin 15 on the side hanger 7, ensuring that the side hanger 7 is always parallel to the pull rod 14, and preventing the side hanger 7 from shifting downward due to gravity.

[0032] Both ends of the slide rail 11 are connected to baffles 16;

[0033] When the slide block 12 slides to both ends of the slide rail 11 and abuts against the baffle 16, the side hanger 7 and the hanging plate 1 are parallel. The baffle 16 can prevent the slide block 12 from sliding excessively and falling off the slide rail 11, and can also serve as a basis for judging when the side hanger 7 and the hanging plate 1 are parallel.

[0034] Mounting studs 23 are provided at symmetrical positions on the top of the slide plate 3 with the slide rail 11 as the center. Side mounting plates 22 that can be detachably sleeved on the mounting studs 23 are connected to both sides of the slide rail 11. The part of the mounting stud 23 above the side mounting plate 22 is threaded with a sixth nut 24. The side mounting plate 22 and the sixth nut 24 can facilitate the installation and removal between the slide rail 11 and the slide plate 3.

[0035] In this invention, the connection position between the side suspension rod 7 and the hanging plate 1 is adjusted by the sliding plate 3, thereby adjusting the lateral distance between multiple side suspension rods 7 located on the same side of the hanging plate 1. This facilitates flexible adjustment during actual arrangement. Simultaneously, by driving the sliding block 12 to change its position on the slide rail 11, the side suspension rod 7 and the sliding plate 3 are rotated, allowing for adjustment of the side suspension rod 7 at different angles from parallel to perpendicular to the hanging plate 1. This facilitates flexible adjustment of the connection angle between the side suspension rod 7 and the hanging plate 1 during actual arrangement, and further facilitates the arrangement of suspension rods in different horizontal directions within the plane of the side suspension rod 7. The device allows for hanging items, and by adding a movable hanging rod 9 below the side hanging rod 7 that can rotate at any angle with the side hanging rod 7, the use of the first threaded mounting hole 10 and the second threaded mounting hole 25 further increases the number of horizontal mounting positions for hanging items, improving the adjustability during actual arrangement. When not in use, the side hanging rod 7 and the hanging plate 1 can be made parallel by sliding the slide block 12 to the end of the slide rail 11, reducing the horizontal footprint of the hanging plate 1 and multiple side hanging rods 7 without disassembly, thus reducing the difficulty of actual arrangement while facilitating storage.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
