Description

Technical Field

[0001] This utility model relates to the field of stage equipment technology, specifically a multi-layer stage lighting lifting device. Background Technology

[0002] With the booming development of the cultural performance industry, the demand for visual presentation in stage art is becoming increasingly diversified. As the core carrier of stage narrative, lighting is being used in large-scale concerts, theatrical performances, variety show recordings, and exhibitions. Audiences' pursuit of immersive viewing experiences is driving stage lighting to evolve from a two-dimensional layout to a three-dimensional and dynamic one. At the same time, the increasing complexity of stage scenes further requires lighting equipment to adapt to multi-dimensional spatial changes and create more layered and impactful visual effects through the synergy between lighting and stage machinery.

[0003] Regarding the fixed installation of lighting fixtures, in most small and medium-sized stages or temporary performance scenarios, the fixtures are fixed to the stage truss, side frame, or ground lighting rig using bolts, clips, and other connectors. Before the performance, the installation position is determined by measuring with a tape measure and calibrating with a level. Once installed, the fixtures cannot be adjusted, but their own angle adjustment function can be used to adapt to limited scenarios. Some large theaters are equipped with fixed rail lighting rigs, where the fixtures can slide horizontally along the rails, but this is limited to position adjustment within a single plane. In terms of individual lifting, for the needs of key lighting, the industry has developed individual lighting lifting devices. These devices use a motor to drive a rope reel, ball screw, or hydraulic rod to control the lifting of a single fixture along a fixed rail, commonly seen in concert lead singer positions and theatrical performance areas.

[0004] Existing stage lighting equipment can meet the needs of basic lighting and simple dynamic adjustment, but it still has shortcomings in adapting to multi-layer three-dimensional stage scenes and improving the efficiency and coordination of lighting layout. Existing equipment is either fixed and cannot be moved, or it can only lift a single lamp, and cannot build multi-layer or multi-group three-dimensional lighting arrays. It is difficult to adapt to the needs of multi-layer stages, immersive theaters and other scenes for layered and staggered lighting distribution. Therefore, a multi-layer stage lighting lifting device is proposed. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a multi-layer stage lighting lifting device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer stage lighting lifting device, including a lifting platform, wherein two lifting platforms are provided, and multiple sets of traction ropes are connected inside the lifting platforms through multiple sets of rope winders of different diameters. A lamp holder is fixedly installed at the end of the traction rope, and a fixed cylinder is fixedly installed at the end of the traction rope. A fixed block is slidably installed at the bottom of the lamp holder. The fixed cylinder and the fixed block cooperate to lock the traction rope and the lamp holder.

[0007] A pressure rod is slidably installed at the end of the fixed block, and a first slider is fixedly installed at the end of the pressure rod slidably installed on the inner wall of the fixed block. A clamping block is fixedly installed at the top of the first slider. A protrusion is fixedly installed on the outer side of the clamping block, and a window corresponding to the protrusion is opened on the body of the fixed cylinder for the fixed block to bite and lock onto the fixed cylinder. A cover is slidably installed on the outer wall of the traction rope, and a notch corresponding to the clamping block is opened at the bottom of the cover for limiting the position of the clamping block.

[0008] By adopting the above technical solution, the innovative design of multiple rope winders of different diameters and the same power unit breaks through the limitations of traditional single-layer or single lamp lifting. The inside of the lift is connected to multiple sets of traction ropes through multiple sets of rope winders of different diameters. By utilizing the difference in the length of the winding and unwinding ropes caused by the difference in diameter, it can drive multiple layers of lamps to complete the spacing adjustment and create a three-dimensional lighting effect. The expansion action of the clamping block realizes the relative fixation of the fixed block and the fixed cylinder. The protrusion cooperates with the fixed cylinder window to form a locking engagement, improving the reliability of the connection.

[0009] Furthermore, the first slider has two sets of fixed blocks slidably installed on the inner wall of the fixed block, and the two sets of fixed blocks are brought closer or further apart by pressure rods. A telescopic rod is fixedly installed on the inner side of the clamping block, and the two sets of clamping blocks are connected to each other by the telescopic rod. A spring is sleeved on the outer wall of the telescopic rod to drive the two sets of clamping blocks to reset.

[0010] By adopting the above technical solution and utilizing the elastic properties of the spring, the two sets of clamping blocks can be automatically reset, ensuring the reliability of the locked state.

[0011] Furthermore, the lamp holder has multiple sets of mounting holes on its edge, and the mounting holes are circular through holes corresponding to the diameter of the outer wall of the fixing cylinder. The multiple sets of mounting holes are connected and have overlapping edges.

[0012] By adopting the above technical solution, the overall side of the mounting port is wavy, and the fixing cylinder cannot move inside multiple mounting ports after installation, thus ensuring the reliability of the connection.

[0013] Furthermore, a second slider is fixedly installed on the top of the fixing block, and the bottom of the lamp holder is provided with grooves on both sides adjacent to the mounting opening that correspond to the second slider, for sliding the fixing block.

[0014] By adopting the above technical solution, the slide and the second slider are precisely matched to form a guide trajectory, thereby ensuring that the fixed block can move smoothly along the preset path and accurately align with different installation ports, thereby improving the ease of operation of lamp installation and layer adaptation and the versatility of lamp holders.

[0015] Furthermore, the outer side of the cover is provided with multiple sets of elastic buckles, and the outer wall of the fixing cylinder is provided with a slot corresponding to the elastic buckles.

[0016] By adopting the above technical solution, the slot and buckle are precisely matched to form a rigid lock, preventing the cover from loosening and falling off. The bottom structure of the cover fills the gap of the clamping block and restricts the position of the clamping block, thereby further preventing the traction rope from accidentally unlocking the connection with the lamp holder and improving the overall safety of the device.

[0017] In summary, the present invention has the following main advantages:

[0018] This invention, through its innovative design of five different diameter rope reels with the same power unit, breaks through the limitations of traditional single-layer or single-lamp lifting and lowering, achieving differentiated speed lifting and lowering of multiple lamps. Utilizing the difference in rope length resulting from the difference in drum diameter, it allows for flexible control of multiple lamps to dynamically increase or decrease spacing, creating a staggered, three-dimensional layout of lights in vertical space, rather than a fixed arrangement on a single plane. The lamp base has multiple pre-set mounting holes at the bottom matching the number of layers, allowing operators to quickly select the target mounting hole based on the actual number of lamp layers without additional drilling or lamp body modifications. Furthermore, the locking connection between the traction rope and the lamp base is achieved in four steps: squeezing the lever, sliding the fixing block, inserting the fixing cylinder, and releasing the lever, without relying on professional tools. This significantly improves efficiency compared to traditional bolt fixing. The fixing block uses a sliding matching mounting hole method, enhancing the lamp base's versatility. The secondary protection of the cover resists the impact of stage vibrations and sudden loads on the springs, completely eliminating the risk of accidental unlocking and falling of the lamps, providing a solid guarantee for performance safety.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Example 1: A multi-layer stage lighting lifting device, such as... Figure 1-6 As shown, the system includes a lift 1, of which two lifts are provided. Inside the lift 1, multiple sets of traction ropes 3 are connected by multiple sets of rope winders of different diameters. The ends of the traction ropes 3 are fixedly installed with lamp holders 2. Through the innovative design of multiple sets of rope winders of different diameters and the same power unit, the limitations of traditional single-layer or single lamp lifting are broken. Inside the lift 1, multiple sets of traction ropes 3 are connected by multiple sets of rope winders of different diameters. By utilizing the difference in the length of the ropes due to the difference in diameter, multiple layers of lamps can be driven to complete the spacing adjustment and create a three-dimensional lighting effect. The ends of the traction ropes 3 are fixedly installed with fixed cylinders 32, and the bottom of the lamp holders 2 is slidably installed with fixed blocks 21. The connection position can be flexibly adjusted to adapt to different installation positions of the fixed cylinders 32. The fixed cylinders 32 and fixed blocks 21 work together to achieve quick locking through mechanical interlocking, which is used for locking the installation between the traction ropes 3 and the lamp holders 2.

[0029] A pressure rod 213 is slidably installed at the end of the fixed block 21, providing a convenient force application point for unlocking operations. The end of the pressure rod 213, which is slidably installed on the inner wall of the fixed block 21, is fixedly installed with a first slider 214 to ensure effective force transmission and component sliding stability. A clamping block 211 is fixedly installed on the top of the first slider 214, and a protrusion 212 is fixedly installed on the outside of the clamping block 211. The expansion action of the clamping block 211 achieves relative fixation of the fixed block 21 and the fixed cylinder 32. The protrusion 212 and the window of the fixed cylinder 32 form a biting lock to improve the connection reliability. The cylinder body of the fixed cylinder 32 has a window corresponding to the protrusion 212 for the fixed block 21 to bite and lock the fixed cylinder 32. A cover 31 is slidably installed on the outer wall of the traction rope 3, and a notch corresponding to the clamping block 211 is opened at the bottom of the cover 31 to limit the position of the clamping block 211. It can move flexibly along the traction rope 3 for easy installation. By filling the gap, the displacement of the clamping block 211 is limited to restrict the position of the clamping block 211 and prevent accidental unlocking.

[0030] Please see Figure 1-6 Two sets of first sliders 214 are slidably installed on the inner wall of fixed blocks 21, and the two sets of fixed blocks 21 are brought closer or further apart by pressure rods 213. By applying pressure to the outside of pressure rods 213, the clamping blocks 211 are contracted and expanded to complete locking and unlocking. A telescopic rod 216 is fixedly installed on the inner side of the clamping blocks 211 to ensure that the movement direction of the clamping blocks 211 does not deviate, thereby improving the stability of the connecting mechanism. The two sets of clamping blocks 211 are connected to each other by telescopic rods 216. A spring 215 is sleeved on the outer wall of telescopic rods 216 to drive the two sets of clamping blocks 211 to reset. By utilizing the elastic properties of springs 215, the two sets of clamping blocks 211 can automatically reset, ensuring the reliability of the locked state.

[0031] Please see Figure 1-6 The lamp holder 2 has multiple sets of mounting holes 201 on its edge. The lamp holder 2 has multiple sets of mounting holes 201 pre-cut, and the connection position can be flexibly selected according to the number of layers of the lamp, which can adapt to the installation needs of different numbers of multi-layer lamps. The mounting holes 201 are circular through holes corresponding to the outer diameter of the fixing cylinder 32, which ensures that there is no radial shaking after the fixing cylinder 32 is inserted, thus improving the tightness of the connection. Furthermore, the multiple sets of mounting holes 201 are connected and overlapped at the edges, so that the overall side of the mounting holes 201 is wavy. After installation, the fixing cylinder 32 cannot move inside the multiple sets of mounting holes 201, thereby ensuring the reliability of the connection after completion.

[0032] Please see Figure 1-6 The top of the fixing block 21 is fixedly installed with a second slider 217. The second slider 217 provides a stable carrier for sliding, avoiding jamming or displacement when the fixing block 21 moves. The bottom of the lamp holder 2 is provided with grooves on both sides adjacent to the mounting port 201, which correspond to the second slider 217. These grooves are used to slide the fixing block 21. The grooves and the second slider 217 are precisely matched to form a guide trajectory, thereby ensuring that the fixing block 21 can move smoothly along the preset path and accurately align with different mounting ports 201. This improves the ease of operation for lamp installation and layer adaptation, as well as the versatility of the lamp holder 2.

[0033] Please see Figure 1-6 The outer side of the cover 31 is provided with multiple sets of elastic buckles, which can be quickly engaged and disengaged without tools. The outer wall of the fixing cylinder 32 is provided with a slot corresponding to the elastic buckle. The slot and buckle are precisely matched to form a rigid lock, preventing the cover 31 from loosening and falling off. The bottom structure of the cover 31 fills the gap of the clamping block 211 and restricts the position of the clamping block 211, thereby further preventing the traction rope 3 from being accidentally unlocked from the lamp holder 2 and improving the overall safety of the device.

[0034] The working principle of this utility model is as follows: The elevator 1 is equipped with five groups of rope winders with different diameters for winding ropes. With the same power device, the larger the diameter of the drum, the longer the traction rope 3 is, and the smaller the diameter, the shorter the winding and unwinding length is. When the rope winder drum is winding and unwinding the traction rope 3, it can widen or narrow the spacing between the lamps, so that the lamps can achieve a three-dimensional lifting and lowering performance during the lifting and lowering process. By pulling four traction ropes 3 through two elevators 1, each lamp is lifted and lowered synchronously, so that the lamps are lifted and lowered in a horizontal state.

[0035] Each set of traction ropes 3 and lamp holders 2 are fixedly installed through a fixing cylinder 32 and an installation port 201. After selecting the target installation port 201 according to the number of lamp layers, the operator pinches the pressure rods 213 at both ends of the fixing block 21 with both hands and applies pressure to the middle. At this time, the two sets of pressure rods 213 drive the first sliders 214 at the ends to move in adjacent directions along the internal sliding groove of the fixing block 21. The clamping blocks 211 at the top of the two sets of first sliders 214 retract synchronously to the middle. At this time, the spring 215 is compressed and stores energy, and the telescopic rod 216 shortens synchronously with the retraction of the clamping blocks 211. When the fixing... Block 21 slides along the groove at the bottom of lamp holder 2 to the position of the corresponding mounting port 201 via the second slider 217. The fixed cylinder 32 at the end of the traction rope 3 is vertically inserted into the mounting port 201. Then the pressure rod 213 is released, and the spring 215 releases its elastic potential energy by losing the pressure of the clamping block 211. This pushes the two sets of clamping blocks 211 to cause the protrusion 212 to expand in opposite directions. When the outer wall of the clamping block 211 touches the inner wall of the fixed cylinder 32, the protrusion 212 is embedded in the window of the fixed cylinder 32, forming an interlocking structure, which plays the role of locking the lamp holder 2 to the fixed cylinder 32.

[0036] After the fixed cylinder 32 and the lamp holder 2 are locked, the operator slides the cover 31 down the traction rope 3 to the top of the fixed cylinder 32. During the sliding process, the cover 31 is aligned with the two sets of clamping blocks 211 that have been expanded into place through the notch at the bottom of the cover 31 to ensure that the cover 31 is not blocked by the clamping blocks 211. Then the cover 31 is pressed into the fixed cylinder 32. The elastic buckle on the outside of the cover 31 engages with the groove on the outer wall of the fixed cylinder 32, realizing the quick connection between the cover 31 and the fixed cylinder 32. At this time, the bottom of the cover 31 fills the gap between the two sets of clamping blocks 211. Even if the spring 215 is slightly deformed due to stage vibration or sudden load during the use of the lamp, the clamping blocks 211 are also restricted by the cover 31 and cannot retract to the middle. The protrusion 212 always remains inside the window of the fixed cylinder 32, completely eliminating the risk of accidental unlocking.
