Description

Technical Field

[0001] This utility model relates to a cable transport protection device, specifically, to a cable reel transport bracket. Background Technology

[0002] Cable reels are indispensable basic equipment in fields such as power, communications, and engineering, used for winding and transporting large quantities of cables. A fully loaded cable reel can weigh several tons or even more than ten tons, and its stable fixation during storage and road transportation is a major safety challenge.

[0003] Currently, there are two main methods for securing cable reels: one is to directly bind them to the transport vehicle using steel wire ropes or chains, and the other is to use a dedicated steel structure bracket for support and fixation. The steel wire rope binding method has disadvantages such as low assembly and disassembly efficiency, difficulty in controlling pre-tension, and susceptibility to wear. Furthermore, it is prone to loosening during long-distance, bumpy transport, causing the cable reel to roll and potentially leading to serious safety accidents. While dedicated steel structure brackets provide more stable support, they generally suffer from the following technical defects:

[0004] Firstly, the most common cable trays use square steel pipes or channel steel welded into a grid-like frame as the main load-bearing structure. This type of material has sharp edges and corners, with 90° sharp angles at the planar joints. The side plate of the cable reel, however, is a complete arc surface. When a heavy cable reel is placed on the tray, its arc surface forms line contact or very small point contact with the right-angled edges of the tray. Under the pressure of several tons, the contact area generates enormous pressure, easily leading to localized impacts and deformation of the cable reel's side plate. A deformed cable reel not only damages itself but also compresses the cable inside, causing damage to the cable insulation layer, affecting its electrical performance and service life, resulting in "secondary damage."

[0005] Secondly, existing cable trays are mostly rigid, welded-in-one structures. The moment the cable reel is hoisted and placed, a tremendous impact is generated; during road transport, vehicle bumps also produce continuous vibrations. These impacts and vibrations are transmitted to the cable reel and cable without any buffering through the rigidly connected trays, posing a potential threat to the cable reel's structure and the cable's performance.

[0006] Furthermore, different engineering projects use a wide variety of cable reel diameters. Existing cable trays are typically designed for specific diameter reels, lacking versatility. Customizing dedicated trays for different cable reels is costly and inconvenient to manage.

[0007] Therefore, there is an urgent need in this field for a new type of cable reel transport bracket that can not only effectively prevent the cable reel from rolling, but also solve the stress concentration problem at the contact point between the cable reel and the bracket, and provide a certain buffering and shock absorption function. At the same time, it can also adapt to cable reels of different specifications, so as to overcome the above-mentioned defects of the prior art. Utility Model Content

[0008] To address the shortcomings of the existing technology, this utility model provides a cable reel transport bracket with a simple structure that prevents the cable reel from rolling and protects the cable from deformation.

[0009] The technical solution adopted by this utility model is:

[0010] A cable reel transport bracket includes a grid-shaped frame body. The frame body includes a lower support beam and an upper support beam. The lower support beam includes a left support beam and a right support beam. The upper support beam includes a front support beam and a rear support beam arranged opposite to each other. The inner sides of the front support beam and the rear support beam are provided with arc-shaped support plates for supporting the cable reel.

[0011] The arc-shaped support plate has a continuous corrugated cross-section, which is used to buffer impacts and vibrations through its own structural elastic deformation.

[0012] Preferably, the two ends of the arc-shaped support plate are provided with horizontal connecting plates, and the horizontal connecting plates are detachably connected to the front support beam and / or the rear support beam by fasteners.

[0013] Preferably, the radius of curvature of the arc-shaped support plate is adapted to the radius of curvature of the side plate of the cable reel to be supported.

[0014] Preferably, the surface of the arc-shaped support plate is provided with an anti-slip structure, which is one of a rubber pad, a pressed pattern, or a protrusion attached to its surface.

[0015] Preferably, the width of the arc-shaped support plate is greater than the thickness of the cable reel side plate.

[0016] Preferably, the frame body is further provided with an adjustable tensioning device, which includes a rotating tube with internal threads of opposite directions at both ends. Threaded rods are connected to both ends of the rotating tube through the internal threads, and a connecting hook is provided at the free end of each threaded rod.

[0017] Preferably, the rotating tube has a through hole in the middle along the radial direction for inserting an operating rod.

[0018] Preferably, a nut is fixedly fitted in the middle of the rotating tube.

[0019] Preferably, a reinforcing support beam is provided below the front support beam and the rear support beam. The two ends of the reinforcing support beam are fixedly connected to the left support beam and the right support beam, respectively, and its top end is fixedly connected to the corresponding front or rear support beam.

[0020] Preferably, the corrugated arc support plate 6 has a wave height of 5-15mm and a wave pitch of 20-50mm.

[0021] The advantages of this utility model over the prior art are:

[0022] Firstly, it possesses excellent buffering and shock absorption performance, effectively protecting the cable reel and cable: 1. Buffering impact loads: When hoisting and placing a cable reel weighing several tons, a huge impact force is generated. The corrugated structure can effectively absorb and dissipate the impact energy through the elastic bending deformation of the material between its troughs and crests, transforming the violent instantaneous impact into a gentle buffer dynamic load, thus greatly avoiding the deformation of the cable reel side plates due to instantaneous overload. 2. Attenuating continuous vibration: During long-distance road transportation, vehicle bumps generate continuous vibration. As a continuous elastic body, the corrugated arc plate can undergo slight elastic deformation with the vibration, forming a natural "shock absorber" that continuously attenuates the vibration energy transmitted from the bracket to the cable reel. This effectively prevents fatigue loosening of the cable reel structure and wear of the internal core wires of the cable caused by long-term vibration, especially playing a crucial protective role for the insulation layer.

[0023] Secondly, this invention completely solves the problem of stress concentration and prevents cable reel deformation due to compression. It uses an arc-shaped support plate with a matching curvature to contact the cable reel's side plate, transforming the harmful line contact (or point contact) of traditional square steel brackets into a safe and uniform surface contact. This disperses the pressure of several tons onto a larger contact area, drastically reducing the pressure on the contact surface and fundamentally eliminating the risk of the cable reel's side plate being deformed by the sharp corners of the bracket, thus protecting the integrity of the cable reel.

[0024] Furthermore, its versatility and adaptability significantly reduce equipment and management costs. Through the design of detachable, curved support plates (such as bolted connections), users can quickly replace the plates with curved plates that match the radius of curvature of the cable reels being transported. This allows a single bracket body to accommodate various cable reel sizes, achieving a universal and modular application. This avoids the high cost of customizing dedicated brackets for each cable reel size, while also reducing the complexity of warehousing and management, bringing customers significant economic benefits and convenience.

[0025] Meanwhile, this invention is easy to operate, highly safe, and convenient to maintain. The adjustable tensioning device (such as a bidirectional threaded rotary tube) is simple and intuitive to operate. Rotating the central rotary tube quickly tightens or loosens the threaded rods on both sides, achieving the fastening and release of the cable reel, with a working efficiency far exceeding that of traditional wire rope binding. This device provides a stable and reliable pre-tension force and facilitates inspection and re-tightening during long-distance transportation, ensuring the safety and reliability of the entire transportation process. It offers two implementation methods: through-hole and nut, adaptable to tools under different working conditions (such as pry bars or torque wrenches), providing high operational flexibility.

[0026] Finally, anti-slip and limiting features comprehensively ensure transportation safety. Anti-slip structures (such as rubber pads and patterns) are added to the surface of the curved support plate, significantly increasing the friction between it and the cable reel side plate. This effectively prevents minor slippage or displacement of the cable reel on the curved plate surface, providing extra safety, especially during sudden braking or turning. The curved support plate, wider than the cable reel side plate, and the optional limiting plate design naturally limit the cable reel in the width direction, further enhancing its stability on the bracket. The structure is robust and has a strong load-bearing capacity. The reinforced support beams greatly enhance the overall structural rigidity and strength of the bracket, enabling it to safely withstand the load of heavy cable reels, preventing deformation of the bracket body under heavy pressure, and ensuring long-term durability and reliability.

[0027] In summary, this utility model not only solves the core problem of cable reels being bumped by sharp corners of traditional brackets, but also endows them with excellent dynamic buffering performance through an innovative corrugated structure. At the same time, it takes into account versatility, ease of operation and overall safety, providing a comprehensive and optimized cable reel transportation solution.

[0028] This utility model cable reel transport bracket addresses the issue that when cables are transported to high-altitude and high-latitude regions for use, the temperature difference between the cable reel at the factory and the high-altitude and high-latitude regions increases. Therefore, it is necessary to adjust the pre-tightening force between the cable reel and the transport bracket according to the temperature changes. The adjustable tensioning device makes adjusting the pre-tightening force more convenient and faster. Attached Figure Description
