Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray for electrical engineering. Background Technology

[0002] Cable trays, as crucial support and protection equipment in electrical engineering, are widely used in building, industrial, and infrastructure construction. They are primarily used for laying power cables, control cables, and communication cables, providing support, fixation, and protection to ensure the safety and stability of the wiring. Cable trays not only allow for the rational planning of wiring routes and improve the neatness of construction, but also reduce damage to cables exposed to the external environment, such as mechanical damage, environmental corrosion, and human interference, thereby extending the service life of the cables and ensuring the stable operation of the power system. With the continuous increase in the demands of electrical engineering, the structure and function of cable trays are constantly being optimized to adapt to various complex construction environments.

[0003] Currently, the most common cable trays on the market include three basic types: ladder type, trough type, and tray type. These trays are usually made of materials such as metal or fiberglass, capable of supporting cables of different specifications and providing a certain degree of support and protection. Traditional cable trays are generally fixed by bolts or welding, and their main function is to provide a routing channel for cables and reduce cable bending damage to some extent. However, in practical applications, cables are usually laid directly inside the tray, relying on their own weight for stability, lacking additional fixing devices. Some trays may be equipped with pressure strips or cable ties for auxiliary fixing, but these fixing methods often cannot guarantee the stability of the cables under external forces or vibrations, and still pose certain safety hazards.

[0004] Traditional cable trays only serve a load-bearing and supporting function, failing to effectively secure cables. This allows cables to shift and rub against external impacts or prolonged vibrations, affecting their safety and lifespan. In high-vibration or high-load environments, such as industrial plants, bridges, and high-rise buildings, loose cables can even lead to safety accidents. Therefore, how to incorporate appropriate fixing structures into cable trays to improve cable stability has become an urgent problem to be solved. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cable tray for electrical engineering, which aims to improve the problem that traditional cable trays only play a role in bearing and supporting, but cannot effectively fix the cables. This can lead to displacement and friction of the cables when subjected to external impact or long-term vibration, thereby affecting the safety and service life of the cables.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable tray for electrical engineering, comprising a shelf, a protective frame fixedly connected to the upper surface of the shelf, a threaded rod internally threaded to the protective frame, a handle fixedly connected to the top of the threaded rod, a clamping plate rotatably connected to the bottom of the threaded rod, an elastic pad fixedly connected to the outer wall of the clamping plate, and a linkage component provided on the outer wall of the elastic pad;

[0007] The linkage assembly includes a first linkage, a turntable, and a second linkage. One end of the first linkage and the second linkage are rotatably connected to the outer wall of the clamping plate, and the other end of the first linkage and the second linkage are rotatably connected to the outer wall of the turntable. A rotating shaft is rotatably connected inside the turntable.

[0008] Furthermore, an extension column is fixedly connected to the outer wall of the shelf, a fixed column is slidably connected to the outer wall of the extension column, a fixing component is provided inside the extension column, a support is fixedly connected to one end of the fixed column, and a mounting plate is fixedly connected to the top of the support.

[0009] Furthermore, the fixing component includes a locking block and a locking groove. The outer wall of the locking block is slidably connected to the interior of the extension column. The locking groove is formed inside the fixing column. A sliding groove is formed inside the fixing column. A bidirectional screw is rotatably connected inside the extension column. A bearing is fixedly connected to the outer wall of the bidirectional screw. The inner thread of the locking block is connected to the outer wall of the bidirectional screw. A limit block is fixedly connected to the outer wall of the locking block.

[0010] Furthermore, the outer wall of the limiting block is slidably connected to the inside of the extension column, and the limiting block is used to limit the movement of the card block.

[0011] Furthermore, the outer ring of the bearing is fixedly connected inside the extension column, and the bearing is used to limit the bidirectional screw.

[0012] Furthermore, the outer wall of the card block is slidably connected to the inside of the card slot, and the outer wall of the bidirectional screw is slidably connected to the inside of the slide groove.

[0013] Furthermore, the slot and the slide are connected to limit the bidirectional screw and the locking block.

[0014] Furthermore, the turntable is elliptical in shape and is rotatably connected inside the protective frame to drive one end of connecting rod one and one end of connecting rod two to move.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the cooperation between the threaded rod and the protective frame enables the clamping plate to move synchronously relative to each other, and the elastic pad clamps and limits the cable, which can effectively prevent the cable from shifting and rubbing due to vibration or external force, thus improving the safety and service life of the cable. In addition, the structure is simple and easy to operate, and can quickly complete the fixing of the cable, improving construction efficiency.

[0017] 2. In this utility model, the cooperation between the bidirectional screw and the locking block allows the locking block to slide within the internal slots of the fixed column and the extension column, thereby realizing the adjustable function of the storage plate. This allows for flexible adjustment of the cable tray storage space according to actual needs, adapting to the requirements of different specifications and quantities of cables. This not only improves the applicability of the cable tray but also enhances the stability of the overall structure, meeting the usage requirements in complex engineering environments.

[0024] 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.

[0025] Reference Figures 1-3This utility model provides an embodiment of a cable tray for electrical engineering, including a shelf 1. A protective frame 2 is fixedly connected to the upper surface of the shelf 1, providing an overall support structure and forming a sliding guide rail for the clamping plate 5. A threaded rod 4 is threadedly connected to the inside of the protective frame 2, forming a threaded engagement relationship with the protective frame 2. Its rotation can be converted into linear movement, driving the clamping plate 5 to slide inside the protective frame 2. A handle 3 is fixedly connected to the top of the threaded rod 4 for manually or electrically driving the clamping mechanism of the entire device. Rotating the handle 3 can drive the threaded rod 4 to rotate, thereby realizing the movement of the clamping structure. The clamping plate 5 is rotatably connected to the bottom of the threaded rod 4. An elastic pad 6 is fixedly connected to the outer wall of the clamping plate 5, mainly used for clamping cables. During synchronous movement, the elastic pad 6 provides a buffering effect to prevent the cables from being damaged due to excessive clamping force. The outer wall of the elastic pad 6 is provided with a linkage component.

[0026] The linkage assembly includes a first linkage 7, a turntable 8, and a second linkage 10. One end of the first linkage 7 and the second linkage 10 are rotatably connected to the outer wall of the clamping plate 5, and the other end of the first linkage 7 and the second linkage 10 are rotatably connected to the outer wall of the turntable 8, connecting the turntable 8 to the clamping plate 5 on the other side, so that the clamping plate 5 on the other side can move synchronously with the clamping plate 5 on the first side, achieving the effect of double-sided clamping. The turntable 8 is rotatably connected to a rotating shaft 9, which supports the turntable 8 and allows it to rotate around itself.

[0027] Specifically, the cable is first passed through the gap between the two clamping plates 5 for subsequent clamping operations. During operation, the handle 3 is driven manually or electrically, causing the handle 3 to rotate the threaded rod 4 inside the protective frame 2. Because there is a threaded engagement between the threaded rod 4 and the protective frame 2, this threaded design ensures stable linear movement when the threaded rod 4 rotates, thus pushing the clamping plate 5 to slide along the internal track of the protective frame 2. The movement of the clamping plate 5 is not just a single motion; it also achieves a more complex linkage effect through the movement of the connecting rod 7 connected to it. When plate 5 slides along the inside of the protective frame 2, the part where one end of it is connected to connecting rod 7 will be subjected to traction force, causing one end of connecting rod 7 to move accordingly. At the same time, the other end of connecting rod 7 is connected to turntable 8. As connecting rod 7 moves, it will drive turntable 8 to rotate along the outer wall of rotating shaft 9, which can convert the motion from linear motion to rotational motion. Then, through the connection between the other end of turntable 8 and connecting rod 10, the rotational motion is converted back into linear motion. The other end of connecting rod 10 is connected to the opposite clamping plate 5. Therefore, through the traction of connecting rod 10, the synchronous movement of the opposite clamping plate 5 is achieved.

[0028] Reference Figures 1-4An extension column 11 is fixedly connected to the outer wall of the shelf 1, and can slide inside the fixed column 16 to adjust the position of the shelf 1 to ensure it can adapt to different construction needs. The fixed column 16 is slidably connected to the outer wall of the extension column 11. A fixing component is provided inside the extension column 11. A support 19 is fixedly connected to one end of the fixed column 16, and a mounting plate 20 is fixedly connected to the top of the support 19. The fixing component includes a locking block 14 and a locking groove 17. The outer wall of the locking block 14 is slidably connected inside the extension column 11 and cooperates with the double-acting screw 12. Under its drive, it slides along the locking groove 17, which plays a limiting and fixing role. The locking groove 17 is opened inside the fixed column 16 and is set inside the fixed column 16 and the extension column 11 to provide sliding guidance for the locking block 14, so that it remains stable during movement. A sliding groove 18 is opened inside the fixed column 16. The double-acting screw 12 with a double-acting thread structure is rotatably connected inside the extension column 11, which can drive both sides simultaneously. The relative movement of the locking blocks 14 enables the adjustment function of the overall device. The outer wall of the bidirectional screw 12 is fixedly connected to the bearing 13. The internal thread of the locking block 14 is connected to the outer wall of the bidirectional screw 12. The outer wall of the locking block 14 is fixedly connected to the limiting block 15 to prevent the locking block 14 from shifting or tilting during movement, thereby improving the accuracy and stability of the overall movement. The outer wall of the limiting block 15 is slidably connected to the inside of the extension column 11. The limiting block 15 is used to limit the locking block 14. The outer ring of the bearing 13 is fixedly connected to the inside of the extension column 11. The bearing 13 is used to limit the bidirectional screw 12. The outer wall of the locking block 14 is slidably connected to the inside of the locking groove 17. The outer wall of the bidirectional screw 12 is slidably connected to the inside of the slide groove 18. The locking groove 17 and the slide groove 18 are connected to limit the bidirectional screw 12 and the locking block 14. The turntable 8 is elliptical in shape and is rotatably connected to the inside of the protective frame 2 to drive one end of the connecting rod 1 7 and the connecting rod 2 10 to move.

[0029] Specifically, the bidirectional screw 12 is designed to pass through the interior of the extension post 11 and engage with it via a threaded connection. In actual operation, rotating the bidirectional screw 12 enables relative movement of the locking blocks 14. The bidirectional screw 12 has a bidirectional threaded characteristic, meaning that during its rotation, it can simultaneously drive the locking blocks 14 on both sides to move in opposite directions, allowing the locking blocks 14 to slide along the length of the extension post 11. Meanwhile, the limiting block 15 acts as a guide, ensuring that the locking blocks 14 do not deviate or tilt during movement. The movement trajectory of the locking blocks 14 is along the extension post 11. The extension column 14 slides within the pre-set slot 17 inside the fixed column 16. The slot 17 provides a precise guiding effect, improving the movement accuracy and stability of the locking block 14. When the operator rotates the bidirectional screw 12 to move the locking block 14 completely into the interior of the extension column 11, the extension column 11 can slide freely inside the fixed column 16. This is achieved by pulling or pushing the extension column 11. The sliding of the extension column 11 will drive the connected shelf 1 to move synchronously, which can realize the precise adjustment of the shelf 1 between different positions to adapt to the use needs of the cable tray in different construction scenarios.

[0030] Working principle: When the cable tray for electrical engineering is needed, the cable is first passed between the two clamping plates 5. Then, the drive handle 3 drives the threaded rod 4 to rotate inside the protective frame 2. With the threaded relationship between the threaded rod 4 and the protective frame 2, the threaded rod 4 drives the clamping plate 5 to slide inside the protective frame 2. At the same time, when the clamping plate 5 moves, it will drive one end of the connecting rod 7 to move. Then, the other end of the connecting rod 7 drives the turntable 8 to rotate on the outer wall of the rotating shaft 9. At this time, the other end of the turntable 8 drives one end of the connecting rod 10 to move. Then, the other end of the connecting rod 10 drives the clamping plate 5 on the other side to move synchronously. Thus, the two clamping plates 5 move synchronously relative to each other. Then, the clamping plate 5 drives the elastic pad 6 to clamp and limit the cable, avoiding random movement and friction.

[0031] Furthermore, the bidirectional screw 12 rotates inside the extension post 11. In conjunction with the threaded relationship between the bidirectional screw 12 and the locking block 14, and the guide of the limiting block 15, the locking blocks 14 on both sides move relative to each other as the bidirectional screw 12 rotates. This causes the locking blocks 14 to slide inside the pre-set slots 17 inside the extension post 11 and the fixed post 16. When the locking blocks 14 have completely moved into the interior of the extension post 11, they can pull the extension post 11 to slide inside the fixed post 16, thereby moving the shelf 1 and achieving distance adjustment.
