Description

Technical Field

[0001] This utility model relates to the field of power and emergency rescue equipment technology, and in particular to a portable cable reel. Background Technology

[0002] In current emergency flood drainage and disaster relief operations, electric pumps are widely used as core drainage equipment. However, the laying and retrieval of their associated cables have long faced significant operational challenges, seriously affecting the efficiency of disaster relief.

[0003] On the one hand, in actual emergency rescue operations, to meet the needs of large-scale drainage, cables are not only heavy individually, but also often laid over distances of tens or even hundreds of meters. Due to the complex on-site environment and operating conditions, cable laying currently still mainly relies on manual labor, carrying and transporting the cables back and forth. Workers not only have to endure extreme physical strain in harsh environments, but also face safety risks such as slipping and bumping. The entire laying process is not only labor-intensive and extremely inconvenient, but also significantly slows down the emergency response speed. On the other hand, after the emergency rescue mission is completed, the temporarily laid cables are often messy and tangled, requiring manual sorting, organization, and coiling for recovery. This usually requires multiple people working together, which is time-consuming and labor-intensive, increasing labor costs and operating time. Utility Model Content

[0021] 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.

[0022] The purpose of this utility model is to provide a portable cable reel to solve the problems existing in the prior art, enabling flexible movement, convenient laying and efficient recycling of cables, improving work efficiency and reducing the labor intensity of personnel.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a portable cable reel, such as Figures 1-2 As shown, the cable reel assembly includes a support frame 1, wheels 2, a reel assembly 3, and a crank 4. Wheels 2 are mounted on the bottom of the support frame 1. The reel assembly 3 includes a rotating shaft 6, a reel 7, and a transmission assembly. The reel 7 is fixedly mounted on the rotating shaft 6, which is rotatably connected to the support frame 1. The crank 4 is rotatably connected to the support frame 1 and is connected to the rotating shaft 6 via the transmission assembly. Turning the crank 4 causes the transmission assembly to operate and drives the rotating shaft 6 to rotate. The wheels 2 at the bottom of the support frame 1 allow the cable reel 7 to be easily pushed or pulled to the work site, reducing manual handling effort and providing high portability. This makes it suitable for on-site work scenarios requiring mobile cabling, such as power construction, communication cabling, and equipment maintenance. The crank 4 transmits the force of manual rotation to the transmission assembly, which drives the rotating shaft 6 to rotate, simultaneously rotating the reel 7 to achieve cable winding, storage, or release. The portable cable reel primarily relies on mechanical transmission, making maintenance convenient, cost-effective, and suitable for environments without power.

[0025] In a further preferred embodiment of this utility model, the portable cable reel also includes a handle 5, which is connected to the support frame 1. The handle 5 provides the operator with a point of force to push, pull, or manipulate the reel 7, improving the mobility and operability of the equipment.

[0026] In a further preferred embodiment of this utility model, the handle 5 is a telescopic structure. The telescopic structure handle 5 can save space when stored and adapt to different heights or operating scenarios when used, thus improving the convenience of use.

[0027] In a further preferred embodiment of this invention, the transmission assembly includes a large gear 8 and a small gear 9. The large gear 8 is fixedly connected to the crank handle 4, and the large gear 8 meshes with the small gear 9. The small gear 9 is fixedly connected to the rotating shaft 6. Through the gear reduction ratio, the small torque input to the crank handle 4 is converted into a large torque on the rotating shaft 6. The operator does not need to exert much force to rotate the reel 7, making cable winding and unwinding easier, especially suitable for winding heavy-duty cables. Furthermore, the gear transmission system is small in size and lightweight, making it suitable for integration into portable devices without occupying excessive space.

[0028] In a further preferred embodiment of this utility model, the crank handle 4 is a folding crank handle 4. The folding crank handle 4 can be unfolded when in use for manual cranking by the operator; when not in use, it can be folded and stored on the support frame 1 to reduce the overall size, avoid protrusion, and facilitate carrying and storage.

[0029] In a further preferred embodiment of this utility model, the traveling wheel 2 is a planetary traveling wheel 2, which is connected to the support frame 1 via an axle 12. The planetary traveling wheel 2 includes a planetary frame 10 and three planetary gears 11 arranged in a triangle on the planetary frame 10. All three planetary gears 11 are rotatably connected to the planetary frame 10, and the axle 12 is located at the geometric center of the planetary frame 10. The planetary traveling wheel 2 can solve the problems of passability and stability of traditional single-wheel or double-wheel vehicles on complex terrain, and is especially suitable for portable cable reels and other equipment that need to move on uneven ground such as construction sites and outdoors. The three planetary gears 11 are arranged in a triangle, which has good stability and balance in contact with the ground. When the portable cable reel moves in a straight line, two planetary gears 11 on the planetary frame 10 contact the ground and rotate under the action of friction, thereby realizing the translational movement of the entire cable reel 7. When the portable cable reel encounters an obstacle or climbs a staircase, all planetary gears 11 revolve together, and the three planetary gears 11 alternately contact the ground, thereby realizing the function of climbing stairs.

[0030] In a further preferred embodiment of this invention, both the reel 7 and the support frame 1 are made of aluminum alloy. Using a lightweight aluminum alloy frame reduces the weight of the portable cable reel, making it easier to move and carry.

[0031] In a further preferred embodiment of this utility model, the portable cable reel also includes a reverse-locking device. The reverse-locking device includes a ratchet, a pawl, and a tension spring. The ratchet is fixedly connected to the rotating shaft, and the middle part of the pawl is rotatably connected to the support frame. The pawl can engage with the ratchet. One end of the tension spring is fixedly connected to the support frame, and the other end of the tension spring is fixedly connected to one end of the pawl. The tension spring prevents the pawl from contacting the ratchet. The tension spring keeps the pawl from contacting the ratchet teeth. When the reel stops rotating and locking is required, the operator uses external force to overcome the spring force, causing the pawl to engage with the ratchet teeth, thus locking the reel. Releasing the pawl causes it to disengage from the ratchet teeth under the spring force, releasing the lock.

[0032] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
