Description

Technical Field

[0001] This invention relates to the field of lighting equipment hanging technology, specifically to an energy-saving studio lighting equipment hanging device. Background Technology

[0002] The studio lighting equipment hoisting device refers to an integrated steel structure frame extending from the lower chord of the studio roof structural beam to the lighting equipment installation layer. It is an inseparable load-bearing system welded from steel profiles, steel plates, and gratings. It is the core infrastructure supporting, fixing, and adjusting the position of the lighting fixtures, forming the "skeleton" of the lighting system. Its core function is to ensure the stable suspension, flexible movement, and safe operation of the lighting fixtures. By raising and lowering the lighting fixtures, the height of the fixtures can be adjusted to precisely control the illumination angle, thereby meeting the lighting needs of different program productions. The hoisting power is provided by an electric winch unit, and the hoisting rod is pulled by a steel wire rope. At the same time, the power is physically cut off when the hoisting rod exceeds its travel range to prevent accidents. The hoisting rod is usually made of high-strength materials and has a multi-point load-bearing design to prevent the lighting fixtures from shaking or falling during filming. The intelligent PLC control system improves the positioning accuracy and adapts to the needs of digital lighting programming.

[0003] The lighting requirements of different areas in a studio typically vary, and the lighting fixtures suspended on the booms in different areas will also differ. The distribution of lighting fixtures at both ends of the same boom may also differ, and the weight of different lighting fixtures often varies. When the lighting fixtures on the boom are unevenly distributed or the lighting fixture models are inconsistent, the difference in vertical load on both ends of the boom creates a lateral bending moment, forcing the boom to tilt towards the side with a greater load. If the spacing between the suspension points is too large or the boom itself is not stiff enough, the tilting amplitude will increase significantly. During lifting, starting, or braking, the eccentric load generates a swinging moment due to inertia, exacerbating the swaying. The connection point of the boom on the side with greater force bears periodic alternating stress. During lifting, uneven load causes fluctuations in stress amplitude. After long-term operation, micro-cracks are prone to develop in areas of stress concentration, creating certain safety hazards. Therefore, we propose an energy-saving studio lighting equipment hanging device. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving studio lighting equipment hanging device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving studio lighting equipment hanging device, comprising a lamp grid layer and several hoisting rods fixedly installed on the lamp grid layer. Several pulleys are rotatably installed on the lamp grid layer. A winding reel is fixedly installed at the output end of each hoisting rod. Several steel wire ropes are wound on each winding reel.

[0006] Preferably, several connecting rods are evenly distributed between each balance bar and its corresponding hanger. A pointer is fixedly installed in the middle of each balance bar. Several scale bars are fixedly installed on each fixing component. The scale bars are arranged in a circle and correspond one-to-one with the connecting rods. Each first counterweight and each second counterweight are set in an L-shape and are arranged symmetrically about the center line of the corresponding balance bar. The lower end of each connecting rod is rotatably connected to the corresponding balance bar. A sliding component is rotatably installed on the upper end of each connecting rod. Several limiting components for guiding the sliding component are fixedly installed on the lower end of each hanger. A second spring is fixedly connected between the upper end of each sliding component and the corresponding hanger.

[0007] Preferably, each sliding member has a sliding rod fixedly installed at its upper end, each sliding rod is vertically slidably installed in the corresponding hanging rod at its upper end, each sliding rod has an insertion hole at its upper end, each hanging rod has several insertion rods that cooperate with the insertion holes slidably installed laterally inside, each insertion rod is fixedly connected to the inner wall of the hanging rod with a third spring, each hanging rod has a pull rod on one side, and each insertion rod is fixedly connected to the corresponding pull rod through a rod member.

[0008] Preferably, each first counterweight has several magnetic shafts slidably mounted on one side, and each second counterweight has several limiting holes corresponding to the magnetic shafts. The limiting holes correspond one-to-one with the magnetic shafts, and a magnetic block that is magnetically attracted to the magnetic shaft is fixedly installed on the inner wall of each limiting hole.

[0009] Preferably, each first counterweight and each second counterweight has a number of balls on its inner wall to reduce friction, and each first counterweight and each second counterweight has an elastic pad that is compressed to increase friction on one side.

[0010] Preferably, each first counterweight has several rotating shafts rotatably installed inside, with each rotating shaft corresponding to a magnetic shaft. Each magnetic shaft is laterally slidably connected to the end of its corresponding rotating shaft. Each first counterweight has a knob rotatably installed on it, and each knob is connected to its corresponding rotating shaft by a transmission belt. Each magnetic shaft end has a threaded groove, and each limiting hole end has a threaded strip that mates with the threaded groove fixedly installed on its inner wall.

[0011] Preferably, each boom is fixedly equipped with a balancing component, each balancing component has a balancing groove, the balancing groove is arc-shaped, and the lowest point of the arc is located in the middle of the balancing groove. The midpoint of each balancing groove coincides with the midpoint of the corresponding boom. Each balancing groove is equipped with a rolling ball, and each balancing component has observation grooves on both sides for observing the position of the rolling ball.

[0012] Preferably, two connecting plates are fixedly installed on the drooping section of each wire rope, and a first spring and a flexible sleeve are fixedly installed between each pair of corresponding connecting plates. Each flexible sleeve is fitted over the corresponding first spring, and the length of the flexible sleeve is equal to the length of the wire rope between the two connecting plates and greater than the unstretched length of the first spring.

[0013] Preferably, each hanger is fixedly equipped with several connecting seats, each connecting seat is rotatably equipped with a rotating rod at its upper end, each rotating rod is rotatably equipped with a telescopic rod at its upper end, and the upper end of each telescopic rod is fixedly installed to the lower end of the light grid layer.

[0014] Preferably, each boom hoist is fixedly equipped with a fire stop limiter to prevent the boom from falling or overshooting the top.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a connecting rod to connect the suspension rod and the balance rod, and uses a plug rod to limit the sliding rod, facilitating the installation of the lighting fixtures. When the balance rod is subjected to uneven force, it will rotate and no longer maintain a horizontal state. The larger the rotation angle of the balance rod, the more uneven the force on the balance rod; conversely, when the rotation angle of the balance rod is smaller, the degree of uneven force on the balance rod is smaller. Furthermore, according to the scale bar pointed to by the pointer, it is easy to install the counterweight to keep the balance rod under balanced force, reduce swaying during the lifting process, and ensure the lighting effect in the studio.

[0016] This invention utilizes the cooperation between the magnetic shaft and the limiting hole, as well as the magnetic attraction force generated by the magnetic block on the magnetic shaft, to initially fix the first and second counterweights. At this time, the elastic pad is not compressed, making it easy to manually slide the first and second counterweights to achieve a balanced state for the balance bar. Then, when the knob is rotated, the inner rotating shaft of the first counterweight will rotate synchronously with the magnetic shaft. The threaded groove of the magnetic shaft will cooperate with the threaded strip to further fix the first and second counterweights, and the elastic pad will be compressed, increasing the friction between it and the balance bar, preventing the first and second counterweights from sliding during the lifting process, and ensuring that the balance bar is always under balanced force.

[0017] This invention utilizes an observation groove to observe the position of the rolling ball within the balance groove, thereby determining whether the boom is in a balanced state. By adjusting the length of the corresponding spiral buckle, the rolling ball rolls towards the center of the observation groove, gradually adjusting the boom to a horizontal state. Simultaneously, the corresponding spiral buckle is shortened according to the degree of bending of the flexible sleeve, ensuring that each flexible sleeve is straightened and each wire rope is under tension, making the boom more balanced in terms of force. Furthermore, the telescopic rod prevents the boom from rotating or swaying horizontally, further improving the stability of the boom during lifting and lowering. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-12This invention provides a technical solution: an energy-saving studio lighting equipment hanging device, comprising a light grid layer 1 and a plurality of hoisting rods 2 fixedly installed on the light grid layer 1. A plurality of pulleys 6 are rotatably mounted on the light grid layer 1. A winding reel 4 is fixedly installed at the output end of each hoisting rod 2. A plurality of steel wire ropes 5 are wound on each winding reel 4. One end of each steel wire rope 5 is fixedly connected to the winding reel 4, and the other end of each steel wire rope 5 passes through a corresponding pulley 6 and hangs downwards under gravity. The lower end of each steel wire rope 5 is folded in half and fixedly mounted with a plurality of rope clamps 7. The lower end of each steel wire rope 5 rotates... Each hoist 2 is equipped with a spiral buckle 8 (the spiral buckle 8 is a known existing structure, so it will not be described in detail here). Each hoist 2 has a hoist 10 below it, and each hoist 10 has several clamps 9 fixedly installed on it. Each clamp 9 is rotatably connected to the lower end of the spiral buckle 8, and the clamps 9 correspond one-to-one with the spiral buckles 8. Each hoist 2 is also equipped with a fire-stop limiter 3 (the fire-stop limiter 3 is a known existing structure, so it will not be described in detail here) to prevent the hoist 10 from falling or hitting the top. Each hoist 10 has a balance component 17 fixedly installed, and each balance component 17 contains a balance... Each balancing groove 18 is arc-shaped, with the lowest point of the arc located in the middle of the balancing groove 18. The midpoint of each balancing groove 18 coincides with the midpoint of the corresponding boom 10. Each balancing groove 18 contains a ball 19. Each balancing component 17 has observation grooves 20 on both sides for observing the position of the ball 19. The observation grooves 20 are connected to the balancing groove 18. The ball 19 rolls towards the lowest point in the middle of the balancing groove 18 under the influence of gravity. The position of the ball 19 in the balancing groove 18 is observed through the observation grooves 20, thereby determining whether the boom 10 is in a balanced state. If the boom 10 is not in a balanced state, the ball 19 is not in the middle position of the balance groove 18. By adjusting the length of the corresponding spiral buckle 8, the ball 19 rolls towards the middle position of the balance groove 18, and the boom 10 is gradually adjusted to a horizontal state. Two connecting plates 11 are fixedly installed on the hanging section of each wire rope 5. A first spring 12 and a flexible sleeve 13 are fixedly installed between each pair of corresponding connecting plates 11. Each flexible sleeve 13 is sleeved on the outside of the corresponding first spring 12. The length of the flexible sleeve 13 is equal to the length of the wire rope 5 between the two connecting plates 11 and is greater than the unstretched length of the first spring 12.When the boom 10 is adjusted to a horizontal position, one of the spiral buckles 8 may be adjusted too long, causing the corresponding wire rope 5 to be not taut. This wire rope 5 will not be able to provide tension, and the boom 10 may experience uneven stress. Since the wire rope 5 is not taut, the corresponding first spring 12 will contract to a certain extent, and the corresponding flexible sleeve 13 will bend instead of straightening. The spiral buckle 8 is shortened according to the degree of bending of the flexible sleeve 13, so that each flexible sleeve 13 is straightened. At this time, each wire rope 5 will also be taut and bear tension, making the boom 10 more balanced. Several connecting seats 16 are fixedly installed on each boom 10. Each of the upper ends is rotatably mounted with a rotating rod 15, and each rotating rod 15 is rotatably mounted with a telescopic rod 14 at its upper end. The upper end of each telescopic rod 14 is fixedly installed to the lower end of the light grid layer 1. The boom hoist 2 controls the winding reel 4 to rotate and wind and release the wire rope 5, adjusting the height of the boom 10. The telescopic rods 14 will also extend and retract accordingly. When the boom 10 tilts and no longer maintains a horizontal state, the telescopic rod 14 on one side will extend and the telescopic rod 14 on the other side will shorten, and the two ends of the rotating rod 15 will rotate accordingly. This does not affect the level detection and adjustment of the boom 10. At the same time, the telescopic rods 14 can prevent the boom 10 from rotating or swaying horizontally, further improving the stability of the boom 10 during lifting and lowering.

[0022] Furthermore, a fixing member 21 is fixedly installed at the lower end of each hanging rod 10, and a balance rod 22 for mounting the light fixture is rotatably installed on each fixing member 21. Each fixing member 21 is located in the middle position between the hanging rod 10 and the balance rod 22. Several connecting rods 25 are evenly distributed between each balance rod 22 and the corresponding hanging rod 10. The lower end of each connecting rod 25 is rotatably connected to the corresponding balance rod 22. A sliding member 26 is rotatably installed at the upper end of each connecting rod 25. Several limiting members 30 for guiding the sliding member 26 are fixedly installed at the lower end of each hanging rod 10. A second spring 27 is fixedly connected between the upper end of each sliding member 26 and the corresponding hanging rod 10. A sliding rod 28 is fixedly installed at the upper end of each sliding member 26. Each slide bar 28 is vertically slidably installed in its corresponding hanger 10. Each slide bar 28 has an insertion hole 29 at its upper end. Several insertion rods 31, which mate with the insertion holes 29, are horizontally slidably installed in each hanger 10. Each insertion rod 31 is fixedly connected to the inner wall of the hanger 10 by a third spring 32. Each hanger 10 has a pull rod 33 on one side. Each insertion rod 31 is fixedly connected to its corresponding pull rod 33 via a rod member. Initially, the balance bar 22 is horizontal, each second spring 27 is neither compressed nor stretched, each sliding member 26 is located in the middle of the limiting member 30, each connecting rod 25 is vertical, and each insertion rod 31 is inserted into the insertion hole 29 of its corresponding slide bar 28. The rod 28 is limited by the sliding member 26, and the connection through the connecting rod 25 makes the balance rod 22 subject to tension at multiple points, making the force on the balance rod 22 more balanced and reducing swaying during lifting and lowering. After the lamp is installed, the pull rod 33 is pulled, which drives the plug rod 31 to be pulled out of the plug hole 29. The plug rod 31 no longer limits the sliding member 28, and the third spring 32 is compressed. Since the fixing member 21 is located in the middle position of the balance rod 22, the balance rod 22 rotates according to the force distribution of the lamp. If the lamp is unevenly distributed, the heavier end of the balance rod 22 rotates downward, and the corresponding connecting rod 25 will also rotate accordingly, pulling the sliding member 26 and the sliding member 28 to slide downward along the limiting member 30. The corresponding second spring 27 is stretched. The lighter end of the balance bar 22 will rotate upward, causing the corresponding connecting rod 25 to rotate and push the slider 26 and slide bar 28 upward. The corresponding second spring 27 is compressed. After the slide bar 28 slides upward, the insertion hole 29 is no longer aligned with the insertion rod 31, preventing the insertion rod 31 and pull rod 33 from resetting. At the same time, the elastic force of the second spring 27 causes the balance bar 22 to rotate to a certain angle and then stop rotating, preventing the balance bar 22 from rotating to a vertical state. The greater the rotation angle of the balance bar 22, the longer the second spring 27 at the heavier end will be stretched, and the shorter the second spring 27 at the lighter end will be compressed, indicating that the balance bar 22 is subjected to more uneven force. Conversely, when the rotation angle of the balance bar 22 is smaller, it indicates that the balance bar 22 is subjected to less uneven force.

[0023] Furthermore, a pointer 23 is fixedly installed at the middle position of each balance bar 22, and several scale bars 24 are fixedly installed on each fixing member 21. The scale bars 24 are arranged in a circle and correspond one-to-one with the connecting rods 25. Each balance bar 22 is provided with a first counterweight 34 and a second counterweight 45 to balance the forces at both ends. The first counterweight 34 and the second counterweight 45 are both L-shaped and arranged symmetrically about the center line of the corresponding balance bar 22. Several balls 35 are provided on the inner wall of each first counterweight 34 and each second counterweight 45 to reduce friction. An elastic pad 36 that increases friction under pressure is fixedly installed on one side of each first counterweight 34 and each second counterweight 45. A sliding pad 36 is installed on one side of each first counterweight 34. The system comprises several magnetic shafts 40. Each second counterweight 45 has several limiting holes 41 corresponding to the magnetic shafts 40. Each limiting hole 41 corresponds one-to-one with a magnetic shaft 40. A magnetic block 42, attracted to the magnetic shaft 40, is fixedly installed on the inner wall of each limiting hole 41. Several rotating shafts 38 are rotatably mounted within each first counterweight 34, each corresponding to a magnetic shaft 40. Each magnetic shaft 40 is laterally slidably connected to the end of its corresponding rotating shaft 38. Each first counterweight 34 has a rotatably mounted knob 37, connected to its corresponding rotating shaft 38 by a transmission belt 39. Each magnetic shaft 40 has a threaded groove 44 at its end. A threaded strip 43, matching the threaded groove 44, is fixedly installed on the inner wall of the end of each limiting hole 41. (See attached...) Figure 6As shown, based on the rotation angle of the balance bar 22, the pointer 23 at the lighter end of the balance bar 22 will point to the corresponding scale bar 24. Since a larger swing angle of the pointer 23 corresponds to a scale bar 24 further away from the pointer 23, the larger the swing angle of the pointer 23, the greater the deviation, and the farther the connecting rod 25 corresponding to the indicated scale bar 24 is from the pointer 23; conversely, a smaller swing angle of the pointer 23 indicates a smaller deviation, and the closer the connecting rod 25 corresponding to the indicated scale bar 24 is to the pointer 23. Observe which two scale bars 24 the pointer 23 points to, so that the magnetic shaft 4... After aligning the first counterweight 34 and the second counterweight 45 with the limiting holes 41, merge them between the corresponding two connecting rods 25. After the magnetic shaft 40 is inserted into the limiting hole 41, it will be attracted by the magnetic force of the magnetic block 42 until the end of the magnetic shaft 40 abuts against the threaded strip 43, preventing the first counterweight 34 and the second counterweight 45 from falling off. Simultaneously, the elastic pad 36 is not compressed, thus not affecting the sliding of the first counterweight 34 and the second counterweight 45. The distance between the two connecting rods 25 is greater than the length of the first counterweight 34 and the second counterweight 45. The distance can be reduced according to the indication on the scale strip 24. The installation range is widened, increasing installation speed, but may not be precise enough. In this case, manually slide the first counterweight 34 and the second counterweight 45 to gradually bring the balance bar 22 to a balanced state, resetting the connecting rod 25, sliding member 26, and slide bar 28. The insertion rod 31 will be pushed by the spring force of the third spring 32, re-inserting into the insertion hole 29 to limit the slide bar 28, making the balance bar 22 more stable with multiple points of force. After the balance bar 22 reaches balance, rotate the knob 37. Through the transmission belt 39, all the rotating shafts 38 inside the first counterweight 34 will rotate synchronously. Due to the magnetic shaft 40... The magnetic shaft 40 is laterally slidably connected to the end of the rotating shaft 38. The magnetic shaft 40 will rotate synchronously with the rotating shaft 38. Through the magnetic attraction force generated by the magnetic block 42 on the magnetic shaft 40, the threaded groove 44 of the magnetic shaft 40 will cooperate with the threaded strip 43, so that the distance between the first counterweight 34 and the second counterweight 45 is further reduced, thereby fixing the first counterweight 34 and the second counterweight 45. The elastic pad 36 is compressed, increasing the friction between it and the balance bar 22, preventing the first counterweight 34 and the second counterweight 45 from sliding during the lifting process, so that the balance bar 22 is always under balanced force.

[0024] Specifically, first, the clamp 9 is fixed to the boom 10. The position of the ball 19 in the balance groove 18 is observed through the observation groove 20. If the boom 10 is not in a balanced state, the length of the corresponding spiral buckle 8 is adjusted so that the ball 19 rolls towards the middle of the balance groove 18, and the boom 10 is gradually adjusted to a horizontal state. At the same time, the corresponding spiral buckle 8 is shortened according to the degree of bending of the flexible sleeve 13 so that each flexible sleeve 13 is in a straight state. At this time, each wire rope 5 will also be in a taut state and bear tension, and the boom 10 will be more balanced. Then, the boom machine 2 controls the winding reel 4 to rotate to wind and release the wire rope 5, and adjusts the height of the boom 10. At this time, the telescopic rod 14 will extend and retract accordingly, which can prevent the boom 10 from rotating or swaying horizontally, further improving the stability of the boom 10 during lifting and lowering. Then, the required lamps are installed on the corresponding positions on the balance rod 22. After installation, pull the lever 33 to pull the plug 31 out of the socket 29. The plug 31 no longer limits the slide bar 28. The balance bar 22 will rotate according to the force distribution of the lamp. If the lamp is unevenly distributed, the heavier end of the balance bar 22 will rotate downward. The corresponding connecting rod 25 will also rotate accordingly and pull the sliding member 26 and the slide bar 28 to slide downward along the limiting member 30. The corresponding second spring 27 will be stretched. The lighter end of the balance bar 22 will rotate upward. The corresponding connecting rod 25 will rotate and push the sliding member 26 and the slide bar 28 to slide upward. The corresponding second spring 27 will be compressed. After the slide bar 28 slides upward, the socket 29 will no longer be aligned with the plug 31, preventing the plug 31 and the lever 33 from resetting. At the same time, the elasticity of the second spring 27 will cause the balance bar 22 to rotate a certain angle and then stop rotating, preventing the balance bar 22 from rotating to a vertical position.The larger the rotation angle of the balance bar 22, the more uneven the force on the balance bar 22. Conversely, when the rotation angle of the balance bar 22 is smaller, the unevenness of the force on the balance bar 22 is smaller. The pointer 23 at the lighter end of the balance bar 22 will point to the corresponding scale bar 24. Observe which two scale bars 24 the pointer 23 points to, align the magnetic shaft 40 with the limiting hole 41 one by one, and merge the first counterweight 34 and the second counterweight 45 between the corresponding two connecting rods 25. After the magnetic shaft 40 is inserted into the limiting hole 41, it will be attracted by the magnetic block 42 until the end of the magnetic shaft 40 abuts against the threaded strip 43, so that the first counterweight 34 and the second counterweight 45 will not fall off. Manually slide the first counterweight 34 and the second counterweight 45 to make the balance bar 22 gradually... As the balance is gradually reached, connecting rod 25, sliding member 26, and sliding rod 28 return to their original positions. Insert rod 31, pushed by the spring force of third spring 32, re-inserts into insertion hole 29 to limit sliding rod 28, making the multi-point force distribution on balance rod 22 more stable. After balance rod 22 reaches equilibrium, rotating knob 37 causes all rotating shafts 38 and magnetic shaft 40 within the first counterweight block 34 to rotate synchronously. The threaded groove 44 of magnetic shaft 40 engages with threaded strip 43, further fixing the first counterweight block 34 and second counterweight block 45 together. The elastic pad 36 is compressed, increasing friction with balance rod 22 and preventing slippage between the first counterweight block 34 and second counterweight block 45 during lifting, thus ensuring that balance rod 22 remains under balanced force.
