Description

Technical Field

[0001] This utility model relates to the field of stage hoist control technology, specifically to a stage hoist control device with preset actions. Background Technology

[0002] Stage rigging is mainly used for suspending and raising various stage equipment, such as lighting, curtains, and scenery. It can quickly and accurately adjust the height and position of the equipment according to the needs of the performance, creating different visual effects and scene atmospheres for the performance. The rigging control device can realize remote control of the rigging, including raising, lowering, and stopping operations.

[0003] A search revealed Chinese Patent Publication No. CN221375275U, which discloses a lifting device for stage rigging. This device uses a motor to drive a rotating arm and a rotating disk, causing the disk to move up and down. The rotating disk then uses a push rod to move a sliding ball at its bottom up and down. Since the sliding ball is fitted into the top of a sliding block, it drags the sliding block along the inner wall of the sliding groove, thus adjusting the height of the lighting. This allows for precise control of the rigging height and, due to its rapid adjustment capability, effectively improves work efficiency. The device can quickly adjust the rigging height as needed in different scenarios to adapt to various work requirements.

[0004] The device described above can quickly adjust the height of the rigging rod when in use. However, considering that existing stage performances take many forms and different performance occasions usually require different chandeliers to enhance the atmosphere of the performance, simply adjusting the height of the rigging rod limits the occasions in which the chandeliers can be used, thereby reducing the applicability and effectiveness of the stage rigging rod.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] Reference Figures 1 to 2 The diagram illustrates a stage rigging control device with preset actions, comprising a housing 1, a moving mechanism 2, and an assembly / disassembly mechanism 3. The moving mechanism 2 is located inside the housing 1 and is used to drive the stage rigging to move. It can also preset the actions of the rigging body 21. The assembly / disassembly mechanism 3 is fixedly installed at the bottom of the moving mechanism 2 and is used to assemble and disassemble stage spotlights, improving the efficiency of spotlight assembly and disassembly, thereby increasing the working efficiency of the rigging body 21. The moving mechanism 2 includes the rigging body 21, a translation mechanism 22, a lifting mechanism 23, and a rotating mechanism 24. The rod body 21 is located inside the housing 1, and the translation mechanism 22 is located inside the housing 1. The translation mechanism 22 is used to drive the rod body 21 to move laterally. At the same time, during the movement, it can trigger the action of the lifting mechanism 23 and the rotating mechanism 24. The lifting mechanism 23 is located at the top of the rod body 21. The lifting mechanism 23 is used to drive the rod body 21 to move vertically, thereby driving the spotlight 32 to move up and down. The rotating mechanism 24 is located inside the housing 1. The rotating mechanism 24 is used to drive the rod body 21 to rotate, thereby driving the spotlight 32 to rotate.

[0026] Reference Figure 2 and Figure 3 The lifting mechanism 23 includes a connecting block 231, a connecting rod 232, and a slider 233. The connecting block 231 is rotatably connected to the top of the boom body 21. The vertical movement of the connecting block 231 can drive the boom body 21 to move vertically. One end of the connecting rod 232 is hinged to the left side of the connecting block 231, and the other end of the connecting rod 232 is hinged to the top of the slider 233. The vertical movement of the connecting rod 232 can drive the connecting block 231 to move vertically. The slider 233 is slidably connected to the top of the inner side of the housing 1. When the slider 233 gradually approaches the boom body 21, the connecting rod 232 moves.

[0027] Reference Figure 2 and Figure 3The translation mechanism 22 includes a motor 221, a reciprocating lead screw 222, and a moving block 223. The motor 221 is fixedly installed on the left side of the housing 1 to prevent it from falling off. The output shaft of the motor 221 is fixedly connected to the left end of the reciprocating lead screw 222. By starting the motor 221, the reciprocating lead screw 222 is driven to rotate. The reciprocating lead screw 222 is rotatably connected to the inner side of the housing 1. The rotation of the reciprocating lead screw 222 causes the moving block 223 to reciprocate laterally along the reciprocating lead screw 222. The inner side of the moving block 223 is threadedly connected to the outer circumference of the reciprocating lead screw 222. The movement of the moving block 223 drives the gear 243 to reciprocate laterally, thereby driving the boom body 21 to reciprocate laterally. The back of the moving block 223 is slidably connected to the inner back of the housing 1. The housing 1 guides the moving block 223 to prevent it from shifting during movement.

[0028] Reference Figure 2 and Figure 3 The rotating mechanism 24 includes a rack block 241, a threaded rod 242, a gear 243, a fixed block 244, and a knob 245. The gear 243 is rotatably mounted inside the movable block 223. The rotation of the gear 243 drives the fixed block 244 to rotate. The fixed block 244 is fixedly mounted inside the gear 243, and four sets of fixed blocks 244 are arranged in a circular array. The outer periphery of the threaded rod 242 is rotatably connected to the inner side of the housing 1. The rotation of the threaded rod 242 drives the knob 245 to rotate. The rack block 241 is moved laterally. Knob 245 is fixedly installed on the left end of threaded rod 242. By turning knob 245, the operator can easily rotate threaded rod 242 to adjust the position of rack block 241. The inner side of rack block 241 is threadedly connected to the inner side of threaded rod 242. By adjusting the position of rack block 241, the contact position between rack block 241 and gear 243 can be adjusted, thereby adjusting the rotation timing of boom body 21. The outer wall of boom body 21 is provided with a sliding groove.

[0029] Reference Figure 2 and Figure 3 The inner side of gear 243 is slidably connected to the outer periphery of boom body 21, and the fixing block 244 is slidably connected to the inner side of slide groove. There are four sets of slide grooves in a circular array. The slide groove and the fixing block 244 limit the boom body 21, so that when gear 243 rotates, it can drive boom body 21 to rotate. The front side of rack block 241 is slidably connected to the inner front end of housing 1. The housing 1 guides rack block 241. Gear 243 meshes with rack block 241. When gear 243 meshes with rack block 241, the lateral movement of moving block 223 can make gear 243 rotate.

[0030] Reference Figure 2 and Figure 3 The lifting mechanism 23 also includes a stop block 234, a guide rod 235, a threaded rod 236, and a knob 237. The stop block 234 is slidably connected to the inner top of the housing 1. The position of the stop block 234 can be adjusted by the sliding effect of the stop block 234. The guide rod 235 is fixedly installed on the inner side of the housing 1. The outer periphery of the guide rod 235 is slidably connected to the inner rear end of the stop block 234. The guide rod 235 guides the stop block 234, thereby preventing the stop block 234 from shifting during movement. The threaded rod... The outer periphery of threaded rod 236 is threadedly connected to the inner front end of stop 234. The outer periphery of threaded rod 236 is rotatably connected to the inner side of housing 1. Through the rotation of threaded rod 236, stop 234 can be moved laterally. Knob 237 is fixedly installed on the left end of threaded rod 236. By using knob 237, it is convenient for the operator to rotate threaded rod 236 to adjust the position of stop 234, thereby adjusting the contact position between stop 234 and slider 233, and thus adjusting the lifting timing of boom body 21.

[0031] Reference Figure 4 and Figure 5 The mounting and disassembly mechanism 3 includes a mounting plate 31, a spotlight 32, a cylinder 33, a circular block 34, and a spiral spring 35. The mounting plate 31 is fixedly installed at the bottom end of the rod body 21. The fixing effect of the mounting plate 31 prevents the mounting plate 31 from falling off. The outer wall of the cylinder 33 is rotatably connected to the inner wall of the mounting plate 31. The rotation effect of the cylinder 33 makes the groove position on the cylinder 33 correspond to the through groove position on the mounting plate 31. The circular block 34 is fixedly installed on the top of the spotlight 32. One end of the spiral spring 35 is fixedly connected to the inner top of the mounting plate 31, and the other end of the spiral spring 35 is fixedly connected to the top of the cylinder 33. Through the elastic force of the spiral spring 35, the cylinder 33 always maintains a fixed position when no external force is applied, that is, the groove position is perpendicular to the through groove position.

[0032] Reference Figures 4 to 6The mounting and disassembly mechanism 3 also includes a spring 36 and a plug rod 37. One end of the spring 36 is fixedly connected to the inner side of the round block 34, and the other end of the spring 36 is fixedly connected to the outer wall of the plug rod 37. Through the elastic force of the spring 36, the plug rod 37 maintains the insertion effect with the groove when no external force is applied, thereby limiting the round block 34 and keeping the spotlight 32 fixed. The round block 34 is inserted into the inner side of the cylinder 33. The bottom of the cylinder 33 has a groove, and the bottom of the mounting plate 31 has a through groove. The outer wall of the plug rod 37 is slidably connected to the inner side of the round block 34. The plug rod 37 is wedge-shaped. The sliding effect allows the insertion rod 37 to engage or disengage with the groove. The outer wall of the insertion rod 37 engages with the inner wall of the groove. When the operator inserts the round block 34 into the cylinder 33, the mounting plate 31 will squeeze the insertion rod 37, causing the insertion rod 37 to retract until the insertion rod 37 corresponds to the groove. Then, the insertion rod 37 will pop out under the action of the spring 36, limiting the round block 34. When the operator rotates the round block 34 until the groove corresponds to the through groove, the insertion rod 37 can move out of the groove and through groove, thereby releasing the limitation on the round block 34. Subsequently, the cylinder 33 will reset under the action of the spiral spring 35.

[0033] This pre-programmable stage hoist control device drives the lifting and rotating mechanisms through the translation mechanism in the moving mechanism. Simultaneously, by rotating knob one or knob two, the working timing of the lifting or rotating mechanisms can be adjusted, thereby achieving the purpose of pre-programming the stage hoist actions, improving the hoist's usage effect and applicability. In addition, the installation and removal mechanism facilitates the quick installation and removal of spotlights by staff, further improving the stage hoist's usage effect and work efficiency.

[0034] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
