Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, specifically to a cable storage device that prevents aging and insulation degradation. Background Technology

[0002] In the construction industry, cables, as the core carrier of power transmission, directly affect construction safety and power transmission stability due to their insulation performance and anti-aging capabilities. However, construction site environments are highly complex and variable, and influenced by natural weather and site conditions, the storage and use of cables face multiple technical challenges.

[0003] I. To prevent cables from aging and losing insulation due to prolonged exposure to sunlight and rain, some construction sites use sheds to centrally protect unused cables. However, during construction, cables need to be frequently retrieved based on the dynamic changes in the construction site, requiring workers to repeatedly move cables between the sheds and the construction points. Due to the significant weight of the cables, each transfer requires substantial manpower, greatly increasing the workload of construction workers and potentially affecting construction progress due to untimely transfers. Furthermore, the cables, once transferred to the construction point, still need to be temporarily placed in the open air, leaving them vulnerable to aging and insulation degradation caused by sun and rain.

[0004] Second, due to their large size and heavy weight, cables present significant operational obstacles during on-site transport. Existing transport methods often rely on multiple construction workers working together or using ordinary trailers. However, construction sites frequently have muddy, gravel-strewn, and uneven surfaces, making ordinary trailers prone to bumps and jams. This not only further increases the manpower required for transport but may also cause damage to the cable's outer layer due to friction with the ground. Furthermore, the method of multiple workers working together makes it difficult to precisely control the speed and direction of cable transport, easily leading to cable collisions and bends, indirectly increasing the risk of insulation damage.

[0005] Third, increased wear and tear during transport exacerbates insulation hazards: Construction sites contain numerous sharp objects such as gravel, metal components, and construction waste. During frequent transport, the cable's outer sheath is easily rubbed and scratched by these objects, leading to sheath damage. As the number of transports increases, the degree of damage gradually worsens, exposing the cable's internal insulation layer to the external environment. This not only accelerates the aging of the insulation layer but also directly leads to a decline in insulation performance. In severe cases, it may cause safety accidents such as leakage and short circuits, posing a significant threat to the personal safety of construction workers and construction equipment.

[0006] In summary, current technical solutions for the storage, protection, transfer, and insulation protection of cables at construction sites have significant shortcomings and cannot simultaneously meet the dual requirements of "effective anti-aging and guaranteed insulation" and "convenient transfer and adaptation to the construction site environment." There is an urgent need for a cable storage device that can solve the above-mentioned technical problems. Summary of the Invention

[0007] The purpose of this invention is to provide a cable storage device that prevents aging and insulation degradation, in order to solve the technical problems mentioned in the background art, such as "heavy load during cable transportation, aging caused by sun and rain, insulation degradation due to wear during transportation, and inconvenience in retrieval".

[0008] To achieve the above objectives, the present invention provides the following technical solution: a cable storage device for preventing aging and insulation degradation, comprising a storage room and multiple cable racks; by adopting the above technical solution, anti-aging and insulation protection of cables during storage is achieved, while solving the problem of heavy transportation burden, making the cable storage and transportation process both efficient and ensuring insulation performance.

[0009] Furthermore, the storage room is equipped with multiple tracks at its bottom, with multiple cable racks correspondingly placed within these tracks. By employing the above technical solution, the tracks limit the movement of the cable racks, preventing them from moving within the storage room, ensuring stable cable storage, and avoiding wear on the outer layer of the cables due to movement or collisions.

[0010] Furthermore, the storage room is equipped with a fence-shaped bottom support frame at the bottom, a triangular rainproof frame at the top, and symmetrical ventilation frames on both sides. By adopting the above technical solution, the bottom support frame provides moisture and insect protection, the rainproof frame prevents rainwater from entering, and the ventilation frames maintain internal air circulation, thus preventing cables from aging and losing insulation due to environmental factors from multiple dimensions.

[0011] Furthermore, a sealing plate is provided on one side of the storage room. The bottom end of the sealing plate is rotatably installed in the storage room, and the top end is provided with a positioning pin. By adopting the above technical solution, the sealing plate is fixed by the positioning pin when closed, isolating it from the external environment; when opened, it forms a pad, which facilitates the sliding and transportation of the cable placement rack, reduces the manpower burden of transportation, and avoids damage to the cables during transportation.

[0012] Furthermore, each cable placement rack has a circular placement groove on its outer side, and mounting shafts are symmetrically arranged on both sides of the circular placement groove. A pulley mounting plate is mounted on the mounting shaft, and a sliding wheel is mounted on the pulley mounting plate. The pulley mounting plate can rotate along the mounting shaft. By adopting the above technical solution, when the sliding wheel is extended, the cable placement rack can be easily moved on the ground, reducing friction between the outer layer of the cable and the ground; when retracted, it facilitates the cable placement rack to be limited within the track, adapting to both storage and transportation scenarios.

[0013] Furthermore, it also includes an arc-shaped pulley fixing plate. The upper ends of the two pulley mounting plates are provided with fixing grooves, and the inner sides are provided with limiting grooves. The pulley fixing plate has limiting blocks at both ends and fixing blocks on both sides in the middle. By adopting the above technical solution, the limiting blocks of the pulley fixing plate can hold the pulley in the extended state when engaged in the limiting grooves, and the fixing blocks can hold the pulley in the retracted state when engaged in the fixing grooves, ensuring the stability of the pulley and preventing accidental switching.

[0014] Furthermore, each of the cable placement racks is equipped with a cable mounting shaft, on which a cable mounting rod is fitted. The cable mounting rod is internally connected to the cable mounting shaft via a bearing. By adopting the above technical solution, the cable reel can rotate flexibly around the cable mounting shaft with the cable mounting rod, avoiding jamming during cable pulling and making the cable retrieval process smoother.

[0015] Furthermore, the cable mounting rod is equipped with multiple rubber anti-slip pads. By adopting the above technical solution, the rubber anti-slip pads increase the friction between the cable reel and the cable mounting rod, preventing slippage when the cable reel rotates, ensuring smooth cable traction, and avoiding cable damage due to slippage.

[0016] Furthermore, the cable placement rack has an opening on one side, with a closing plate at the opening. The closing plate is surrounded by mounting blocks, and the cable placement rack has a matching mounting groove. By adopting the above technical solution, the closing plate, through the cooperation of the mounting blocks and the mounting groove, seals the cable placement rack, isolating it from external dust and gravel during transport, reducing wear on the outer layer of the cable, and preventing the cable reel from accidentally coming off.

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

[0018] 1. This invention utilizes a multi-layered protective structure within the storage enclosure to create a comprehensive protection system for complex construction site environments: the fence-shaped bottom support frame, with its perforated structure, isolates ground moisture and insects, preventing cable insulation degradation due to dampness and mold; the triangular rainproof frame, with its sloping drainage characteristics, quickly channeles rainwater, preventing it from seeping into the storage enclosure and wetting the cable insulation; the side ventilation frames maintain airflow to avoid overheating and accelerated aging, while their built-in dustproof nets prevent construction dust from adhering to the cable surface; and the locking plate, secured by positioning pins, completely isolates the cable from external sources of corrosion such as sunlight, rain, and dust. This structure provides closed-loop protection from multiple dimensions—moisture-proof, rainproof, ventilation, and dustproof—directly solving the problems of accelerated aging and insulation degradation of existing construction site cables due to exposed storage.

[0019] 2. This invention completely changes the traditional manual handling mode through the linkage between the enclosed plate and the sliding structure of the cable placement rack: the bottom end of the enclosed plate of the storage room is rotatably connected, and when opened, it naturally forms an inclined pad, the surface of which smoothly transitions with the ground and the internal track of the storage room; the pulley mounting plate of the cable placement rack can rotate along the mounting shaft, and after the sliding wheels are unfolded, the limiting block of the pulley fixing plate engages with the limiting slot of the pulley mounting plate to achieve locking, allowing the placement rack to slide smoothly along the pad and the track. During transportation, no multiple construction workers are required to lift and transport the cable rack; only one person is needed to push it to complete the storage and retrieval of the cable rack, which not only reduces the labor cost of transportation by more than 80%, but also avoids collision and dragging damage between the cables and the ground and building components during transportation.

[0020] 3. This invention optimizes the cable handling experience through the precise coordination of the internal rotating structure and anti-slip design of the cable placement rack: The cable mounting rod is connected to the cable mounting shaft via bearings, forming a flexible rotating support structure that allows the cable reel to rotate synchronously with the traction action, completely solving the jamming problem caused by high rotational resistance in traditional cable reel handling; the evenly distributed rubber anti-slip pads on the cable mounting rod increase the friction with the inner wall of the cable reel, preventing relative slippage during cable reel rotation and avoiding sudden loosening or collision damage to the cable due to slippage. Simultaneously, the rounded edges of the cable outlet and the slightly larger diameter design further reduce frictional loss between the outer layer of the cable and the outlet during traction, ensuring the integrity of the insulation layer.

[0021] 4. In this invention, the orderly and stable storage of cables is achieved through the combined action of track limiting and sliding wheel retraction positioning: multiple tracks inside the storage room correspond one-to-one with the cable placement racks. The track sidewalls limit the placement racks, preventing displacement caused by construction site vibrations or personnel contact. When the placement rack enters the storage state, the pulley mounting plate is rotated to retract the sliding wheels into the circular placement groove. Then, the fixing blocks of the pulley fixing plate are engaged with the fixing grooves at the upper end of the pulley mounting plate, keeping the sliding wheels in a retracted state and preventing them from protruding and affecting the stable placement of the placement rack within the track. This dual limiting structure ensures that multiple rolls of cable are stored independently without colliding with each other, reducing the risk of insulation damage during storage.

[0022] 5. This invention, through the ingenious combination of a switchable sliding wheel structure, enables the device to simultaneously meet the dual needs of storage and transportation: the sliding wheel mounting plate, with the mounting shaft as its rotation center, can switch between two states—expanded and retracted. When expanded, the limiting blocks and slots of the sliding wheel fixing plate engage to lock the wheel, adapting to ground transportation on construction sites; when retracted, the fixing blocks and slots engage to position the wheel, adapting to the track-based positioning of storage rooms. This "dual-purpose" structural design eliminates the need for additional transportation tools, saving storage space on construction sites, simplifying cable storage and retrieval procedures, and significantly improving the device's adaptability in dynamic construction scenarios.

[0023] 6. This invention provides dual protection during the cable placement process through the coordinated protection of a closed plate and sliding wheels: the open portion of the cable placement rack is sealed by the mounting blocks of the closed plate engaging with the mounting groove of the rack, preventing impurities such as gravel and sand from entering the rack during transport and avoiding scratches to the insulation layer caused by friction between impurities and the cable's outer layer; simultaneously, the extended sliding wheels maintain a gap between the cable placement rack and the ground, reducing direct contact between the cable's outer layer and the ground, and preventing scratch damage to the insulation layer from sharp objects on the ground. This dual protection structure effectively reduces cable loss during transport and extends its service life.

[0024] 7. The design of the various structures in this invention fully considers ease of operation on construction sites: the positioning pins of the sealing plate can be inserted and removed without tools, allowing for quick closing and opening; the locking blocks and slots of the pulley fixing plate adopt an interference fit design, allowing for manual locking and unlocking without additional fasteners; the closing plate is installed via a snap-fit ​​structure, making disassembly and removal convenient, facilitating the placement and replacement of cable reels. All operations require no professional skills or complex tools; construction personnel can become proficient in using the device after simple training, significantly reducing the application threshold and operational error rate.

[0034] The technical solutions of the embodiments 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.

[0035] The embodiments of the present invention will now be described.

[0036] Example 1

[0037] This embodiment provides a cable storage device to prevent aging and insulation degradation, which is suitable for the conventional cable storage and transfer in medium-sized construction sites. The specific structure is as follows: it includes a storage house 1 and multiple cable placement racks 2 for placing cables.

[0038] Storage room's protective and transport adaptation design

[0039] The storage house 1 is installed on the outdoor ground of the construction site or inside the construction site building, serving as the core protective carrier for the cables. Its structural design specifically addresses the cable aging problems caused by sun exposure, rain, moisture, and dust.

[0040] Moisture and insect prevention: The bottom of the storage house 1 is equipped with a bottom support frame 12 in the shape of a fence, with a fence spacing of 5-10cm. This not only ensures the support stability of the storage house 1, but also effectively isolates the moisture and insects from the construction site ground, preventing the insulation performance of the cable from deteriorating due to moisture and mold.

[0041] Rain protection: The top of the storage house 1 is equipped with a triangular rainproof frame 13. The triangular structure can quickly drain rainwater and prevent rainwater from seeping into the interior of the storage house 1 and wetting the cables, thus avoiding cable aging caused by rainwater from the source.

[0042] Ventilation and dust prevention: Ventilation racks 14 are symmetrically installed on both sides of the storage room 1. The ventilation racks 14 penetrate the side walls of the storage room 1 and are equipped with dustproof nets inside. This can maintain air circulation inside the storage room 1, avoid the hot and stuffy environment from accelerating the aging of the cable insulation layer, and prevent construction site dust from entering and adhering to the cable surface, thus reducing the burden of cleaning the insulation layer.

[0043] Meanwhile, the structural design of storage room 1 also solves the problem of "inconvenient transportation":

[0044] Track limiting: Multiple tracks 11 for limiting are provided at the bottom of the storage room 1. Multiple cable racks 2 are placed inside the storage room 1 and each cable rack 2 corresponds to one track 11. The track 11 limits the cable rack 2 to prevent it from moving inside the storage room 1 due to construction site vibration or personnel collision, thus ensuring the stability of cable storage.

[0045] Enclosure Plate Pad: One side of the storage room 1 is equipped with an enclosure plate 15 for closing or opening the internal space. The bottom end of the enclosure plate 15 is rotatably installed on the storage room 1, and the top end is equipped with a positioning pin 16. The storage room 1 has a positioning hole at the corresponding position. When the enclosure plate 15 is closed, the positioning pin 16 is inserted into the positioning hole to lock it, isolating the interior of the storage room 1 from the external environment. When open, one end of it is placed on the ground to form an inclined pad. In conjunction with the sliding structure of the cable placement rack 2, the cable placement rack 2 can be conveniently slidably transferred between the storage room 1 and the construction point without the need for multiple construction personnel to carry it, greatly reducing the manpower burden of transportation, and at the same time avoiding damage to the cables due to collisions and dragging during transportation.

[0046] Sliding and protective design of cable rack

[0047] Each of the cable racks 2 is a circular cylindrical structure, with an internal space suitable for accommodating one roll of standard construction cable (50-200cm in diameter). Its design focuses on solving the problems of "wear during transportation and inconvenience in access".

[0048] Cable outlet protection: The top of the cable placement rack 2 is provided with a cable outlet 21. The diameter of the cable outlet 21 is 2-5cm larger than the diameter of the cable. The opening edge is rounded to facilitate the cable from inside the rack to outside the rack and to prevent the outer layer of the cable from being damaged by friction with the edge of the outlet during the pulling process.

[0049] Sliding wheel deployment / retraction: The cable placement rack 2 has a circular placement groove 22 on its outer side. Two mounting shafts 23 are symmetrically arranged on both sides of the circular placement groove 22. Each mounting shaft 23 has an arc-shaped pulley mounting plate 24, and each pulley mounting plate 24 has a sliding wheel 25. The portion of the sliding wheel 25 protruding from the placement groove 22 is 1 / 3 to 1 / 2 of its diameter. The pulley mounting plate 24 can rotate along the mounting shaft 23. When deployed, the sliding wheel 25 stably contacts the ground, allowing the cable placement rack 2 to move easily on the construction site ground or the pad of the enclosed plate 15 via the sliding wheel 25, reducing direct friction between the outer layer of the cable and the ground and lowering the risk of insulation wear. When retracted, the sliding wheel 25 is stored within the placement groove 22, without affecting the limiting stability of the cable placement rack 2 within the track 11.

[0050] Pulley fixing plate positioning: To ensure the stability of the sliding wheel 25, the device is equipped with an arc-shaped pulley fixing plate 3. The upper end of the two pulley mounting plates 24 is provided with a fixing groove 231 and the inner side is provided with a limiting groove 241. The pulley fixing plate 3 is provided with limiting blocks 32 at both ends and a fixing block 31 in the middle: When the sliding wheel 25 is unfolded, the limiting block 32 is engaged with the limiting groove 241; when it is retracted, the fixing block 31 is engaged with the fixing groove 231 to prevent the sliding wheel 25 from accidentally switching states.

[0051] Cable access stability design

[0052] Each of the cable placement racks 2 is equipped with a cable mounting shaft 26 and a cable mounting rod 27 to solve the problem of "cable rotation jamming and slippage".

[0053] Flexible rotation: The cable mounting rod 27 is connected to the cable mounting shaft 26 through the bearing 271. The cable roll is mounted on the cable mounting rod 27 and can rotate flexibly around the cable mounting shaft 26 with the cable mounting rod 27, avoiding the traction effort caused by rotation jamming during the traditional cable roll handling process;

[0054] Anti-slip and anti-loosening: Multiple rubber anti-slip pads 272 are provided on the cable installation rod 27, which can increase the friction between the cable roll and the cable installation rod 27, prevent the cable roll from slipping when rotating, ensure the cable pulling process is smooth, and avoid the cable from suddenly loosening and colliding and being damaged due to slipping.

[0055] Additional enclosed protective design

[0056] The cable placement rack 2 has an opening on one side for placing cable rolls. A closing plate 273 is provided at the opening. The closing plate 273 is surrounded by mounting blocks. The cable placement rack 2 is provided with an appropriate mounting groove. The closing plate 273 is installed at the opening through the cooperation of the blocks and the groove. This can close the internal space of the cable placement rack 2, further isolate the cable from external dust and gravel during transportation, reduce the wear of the insulation layer, and prevent the cable roll from accidentally coming out of the opening.

[0057] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
