Description

Technical Field

[0001] This utility model relates to the field of suspension device technology, and in particular to a suspension device for air-supported membrane building equipment. Background Technology

[0002] Air-supported membrane structures are a new type of building. They use special membrane materials as their outer shell and rely on air pressure to support the entire structure. Compared to traditional concrete or steel structures, air-supported membrane structures do not require a large amount of building materials or complex construction processes, resulting in relatively lower construction and maintenance costs. The membrane material also has excellent heat insulation and light transmission properties, effectively reducing heat loss from the interior and heat transfer from the outside, thus lowering energy consumption for air conditioning and other equipment. Furthermore, it provides good natural lighting, reducing reliance on artificial lighting during the day and saving energy. In practical use, items such as projectors are often suspended from the top of the air-supported membrane structure. To facilitate the suspension and subsequent maintenance of these items, a suspension device is required.

[0003] A search revealed an equipment suspension device for air-supported membrane structures, publication number CN218114874U. The device comprises an air-supported membrane structure with a base inside. Two support plates are fixedly mounted on the top of the base. An electromagnetic motor is fixedly mounted on the top of the base, and a drive shaft is fixedly mounted on the output shaft of the electromagnetic motor. One end of the drive shaft passes through a corresponding support plate and is rotatably connected to it. A worm gear is rotatably mounted on one side of each support plate, and the drive shaft is connected to the worm gear. A common rotating rod is rotatably mounted on both support plates. A worm wheel is fixedly mounted on one end of the rotating rod, and the worm gear meshes with the worm wheel. A take-up wheel is fixedly sleeved on the rotating rod, and a suspension rope is wound around the take-up wheel. This invention provides an equipment suspension device for air-supported membrane structures that allows for convenient raising and lowering of projection equipment.

[0004] Based on the aforementioned patent, the suspension rope is wound up by a winding wheel. However, the suspension rope needs to suspend the object on the top of the air-supported structure, which makes the suspension rope long. Furthermore, the winding wheel lacks a rope management structure during the winding process, which makes the wound suspension rope tend to concentrate on one side, causing excessive friction and compression of the suspension rope. In response to this technical problem, this application proposes a suspension device for air-supported structure equipment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the winding reel, which lacks a cable management structure during winding, causing the wound-up suspension ropes to tend to concentrate on one side. The invention proposes a suspension device for air-supported membrane structures that evenly distributes the suspension ropes on the winding reel, preventing them from concentrating on one side. This avoids excessive friction, compression, or stretching caused by localized concentration, thereby reducing the risk of rope wear and breakage, extending the overall service life, and ensuring the connecting plate remains stable during lifting and lowering without swaying.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspension device for air-supported membrane building equipment, comprising an air-supported membrane building body, a support frame fixedly connected to the bottom of the inner wall of the air-supported membrane building body, a winding reel rotatably connected to the inner wall of the support frame, a rotating shaft fixedly connected to the front end of the winding reel, the rotating shaft being connected to a reciprocating screw via a transmission assembly, the outer wall of the reciprocating screw being rotatably connected to the inner wall of the support frame, a cable management assembly provided on the outer wall of the reciprocating screw, a suspension rope wound around the outer wall of the winding reel, a plurality of pulleys fixedly connected to the top of the inner wall of the air-supported membrane building body, the suspension rope being connected to a connecting plate via the pulleys, and limit components provided on both the left and right sides of the connecting plate.

[0007] Furthermore, the transmission assembly includes a first pulley fixedly connected to the outer wall of the rotating shaft, the first pulley being connected to a second pulley via the inner side of a transmission belt, and the outer wall of the reciprocating screw being fixedly connected to the inner wall of the second pulley.

[0008] Furthermore, the cable management assembly includes a threaded sleeve fitted on the outer wall of the reciprocating lead screw, a cable management rod fixedly connected to the left end of the threaded sleeve, and the suspension rope passing through the inner wall of the cable management rod.

[0009] Furthermore, a limiting rod is fixedly connected to the right end of the threaded sleeve, a horizontal plate is fixedly connected to the right end of the support frame, and the right end of the limiting rod is slidably connected to the left end of the horizontal plate.

[0010] Furthermore, the limiting component includes a fixing plate fixedly connected to both sides of the bottom end of the inner wall of the air-supported membrane structure. A first sliding plate is slidably connected to the inner wall of the fixing plate, and a second sliding plate is slidably connected to the inner wall of the first sliding plate. The left and right ends of the connecting plate are respectively fixedly connected to the opposite ends of the second sliding plate on the left and right sides.

[0011] Furthermore, a through groove is provided on the inner wall of the top of the fixed plate on the left, and the suspension rope passes through the inner wall of the through groove.

[0012] Furthermore, an electromagnetic motor is fixedly connected to the bottom of the inner wall of the air-supported membrane structure, and the front end of the rotating shaft is fixedly connected to the drive end of the electromagnetic motor.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the reciprocating screw at the top is driven to rotate when the winding reel takes in the rope, which causes the rope guide rod to move back and forth, thereby making the rope evenly distributed on the winding reel. This avoids the rope being concentrated on one side of the winding reel, and avoids excessive friction, compression or stretching caused by local concentration, thereby reducing the risk of rope wear and breakage and extending the overall service life.

[0015] 2. In this utility model, the connecting plate will drive the first sliding plate to slide inside the fixed plate during the lifting process, while the second sliding plate slides inside the first sliding plate, so that the connecting plate remains stable during the lifting process and will not sway left and right.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of a suspension device for air-supported membrane building equipment, comprising an air-supported membrane building body 1, a support frame 5 fixedly connected to the bottom of the inner wall of the air-supported membrane building body 1, a winding reel 4 rotatably connected to the inner wall of the support frame 5, a rotating shaft 3 fixedly connected to the front end of the winding reel 4, a first pulley 6 fixedly connected to the outer wall of the rotating shaft 3, the first pulley 6 being connected to a second pulley 7 via the inner side of a transmission belt, a reciprocating screw 8 fixedly connected to the inner wall of the second pulley 7, the outer wall of the reciprocating screw 8 rotatably connected to the inner wall of the support frame 5, a threaded sleeve 9 sleeved on the outer wall of the reciprocating screw 8, a cable management rod 10 fixedly connected to the left end of the threaded sleeve 9, a suspension rope 13 passing through the inner wall of the cable management rod 10, a limit rod 11 fixedly connected to the right end of the threaded sleeve 9, a horizontal plate 12 fixedly connected to the right end of the support frame 5, the right end of the limit rod 11 slidably connected to the left end of the horizontal plate 12, an electromagnetic motor 2 fixedly connected to the bottom of the inner wall of the air-supported membrane building body 1, and the front end of the rotating shaft 3 fixedly connected to the drive end of the electromagnetic motor 2.

[0025] Specifically, the electromagnetic motor 2 is a motor with a special braking device. When the motor is powered off, the braking device is activated by electromagnetic force, which quickly holds the motor shaft and stops the motor rotor from rotating, thus achieving a function similar to self-locking. The reciprocating screw 8 has a movable part in the thread on its outer wall. The reciprocating screw 8 drives the threaded sleeve 9 to move back and forth through the movable part. The reciprocating screw 8 is existing technology and will not be described in detail. This device can be used to hoist objects such as projectors in the air-supported membrane building 1 to the top, so that the equipment can be kept in a suitable position and posture, ensuring the structural safety of the entire air-supported membrane building.

[0026] Reference Figure 1 , Figure 4 and Figure 5 The outer wall of the winding reel 4 is wound with a hoisting rope 13. Multiple pulleys 14 are fixedly connected to the top of the inner wall of the air-supported membrane structure 1. The hoisting rope 13 is connected to the connecting plate 15 through the pulleys 14. Fixed plates 16 are fixedly connected to both sides of the bottom of the inner wall of the air-supported membrane structure 1. The inner wall of the fixed plate 16 is slidably connected to the first sliding plate 17. The inner wall of the first sliding plate 17 is slidably connected to the second sliding plate 18. The left and right ends of the connecting plate 15 are fixedly connected to the opposite ends of the second sliding plate 18 on the left and right sides, respectively. A through groove is opened on the inner wall of the top of the left fixed plate 16, and the hoisting rope 13 passes through the inner wall of the through groove.

[0027] Specifically, the pulley 14 has the ability to change the direction of force transmission. The direction of the suspension rope 13 can be changed through the pulley 14. When the connecting plate 15 falls, the first sliding plate 17 will first move down in the fixed plate 16. However, when the first sliding plate 17 moves to the bottom of the fixed plate 16, the second sliding plate 18 will move down on the inner wall of the first sliding plate 17, so that the connecting plate 15 continues to fall and remains stable. In actual use, the number of sliding plates can be added according to the specific height of the air-supported membrane structure 1.

[0028] Working principle: When an object is hoisted to the top of the air-supported membrane structure 1, the object is first connected to the connecting plate 15. Then, the electromagnetic motor 2 is started, which drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the winding reel 4 to rotate, winding up the hoisting rope 13. At the same time, the rotating shaft 3 drives the first pulley 6 on the outer wall to rotate. The first pulley 6 drives the second pulley 7 to rotate through the transmission belt. The second pulley 7 drives the reciprocating screw 8 to rotate. The reciprocating screw 8 drives the threaded sleeve 9 on the outer wall to move back and forth. The threaded sleeve 9 drives the cable management rod 10 to move back and forth, causing the inner wall of the cable management rod 10 to move back and forth. The hoisting rope 13 moves back and forth, so that the hoisting rope 13 is evenly distributed on the outer wall of the take-up reel 4 and is not concentrated on one side. When the take-up reel 4 is winding, the hoisting rope 13 changes direction through the pulley 14 and is fixed to the top of the connecting plate 15, thereby moving the connecting plate 15 upward. When the connecting plate 15 moves upward, it will drive the second slide plate 18 to move on the inner wall of the first slide plate 17. When the second slide plate 18 moves to the top of the first slide plate 17, it will drive the first slide plate 17 to move on the inner wall of the fixed plate 16, so that the connecting plate 15 remains vertical during the upward movement and does not sway left and right.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
