A slide rail is provided along the long side of the top surface of the support platform. A slider is installed in conjunction with the slide rail, and the fixed pulley is rotatably connected to the slider. The slider is fixed and limited by equidistant grooves on the side of the slide rail using hexagonal head screws. The two support platforms are connected by a threaded long rod, with nuts at both ends to adjust the distance between the support platforms. The ramp is located in front of the support platforms, and its top height is not lower than the highest point of the fixed pulley. During cable laying, the cable reel rotates in place, and the fixed pulley converts sliding friction into rolling friction, significantly reducing rotational resistance.

Description

Technical Field

[0001] This utility model belongs to the field of cable laying devices, specifically relating to a cable reel support device. Background Technology

[0002] On construction sites, cable laying is a common operation. Cables are typically wound on cable reels, which can be released by rolling. However, when the cable reel is large and heavy, its rolling requires a significant amount of space, and the increased friction with the ground necessitates more manpower. Current solutions involve using a suspension device that passes through a central hole in the cable reel to lift it, allowing it to rotate for cable laying. However, suspending the cable reel requires a crane, which can be difficult to access in space-constrained areas. Furthermore, the installation of the suspension device has specific requirements, and the reel is prone to swaying or even falling off during rotation, resulting in poor safety and practicality. Utility Model Content

[0003] The problem this invention aims to solve is to provide a cable reel support device that can support and rotate the cable reel without the need for a crane, is applicable to cable reels of different sizes, and prevents the cable reel from falling off during rotation.

[0004] A cable reel support device is characterized by comprising a support platform, a fixed pulley, and a ramp. A slide rail is provided along the long side of the top surface of the support platform. The fixed pulley is rotatably mounted on a slider. Two sets of sliders are installed on the support platform in cooperation with the slide rail, and a limiting component is provided between the slider and the slide rail. The ramp is located on the front side of the support platform, and the highest point of the ramp is not lower than the highest point of the fixed pulley. At least two through holes are opened on the side of the support platform. The combination of two support platforms and the ramp is symmetrically arranged, and a long rod is inserted into the through holes to connect the two support platforms. The two ends of the long rod are threaded, and the support platform can move within the threaded range and is fixed and limited by nuts provided outside the through holes on both sides of the support platform.

[0005] Furthermore, the limiting component is a hexagon socket head cap screw. Several grooves are equally spaced on the side of the slide rail. A through hole is opened on the side of the slider at the position corresponding to the groove, and the hexagon socket head cap screw is inserted into the through hole. After the slider slides to the appropriate position, the hexagon socket head cap screw is screwed into the groove to realize the slider limiting.

[0006] Furthermore, the top surface of the slope has a recessed section along its long side at its center.

[0007] The beneficial effects of this utility model are as follows: The cable reel is supported by a set of fixed pulleys on the support platform, and the loading is assisted by a ramp, allowing the cable reel to rotate in place on the fixed pulleys. This eliminates the need for a crane, solving the problem of limited space preventing the use of large equipment, and avoiding the safety risks of suspension devices swaying and falling off. Two support platforms are connected by a threaded long rod, which is locked with nuts after the support platforms are moved, accommodating cable reels of different widths. The slider slides on the slide rail and is fixed by inserting hexagonal screws into the slide rail grooves, allowing for flexible adjustment of the fixed pulley spacing to match the cable reel diameter. The four fixed pulleys form a symmetrical support structure, which, together with the limiting components and the long rod nuts, effectively prevents the cable reel from swaying or falling sideways during rotation, improving operational safety. The fixed pulleys convert the sliding friction between the cable reel and the support surface into rolling friction, significantly reducing rotational resistance, saving manpower, and allowing the cable reel to rotate in place to release the cable without long-distance rolling, reducing site occupation. Using standardized mechanical components such as slide rails, sliders, and threaded rods, installation is convenient and cost-effective, making it suitable for complex construction site environments.

[0011] Example 1: A cable reel support device includes a support platform 1, a fixed pulley 2, and a ramp 3. A slide rail 4 is installed along the long side of the top surface of the support platform 1. The fixed pulley 2 is rotatably mounted on a slider 5. Two sets of sliders 5 are fitted onto the support platform 1 in conjunction with the slide rail 4. A limiting component is provided between the slider 5 and the slide rail 4; the limiting component is a hexagonal head screw 6. Several grooves 7 are equidistantly formed on the side of the slide rail 4. Through holes are formed on the side of the slider 5 at positions corresponding to the grooves, and hexagonal head screws 6 are inserted into the through holes. After the slider 5 slides to a suitable position, the hexagonal head screws 6 are screwed into the grooves 7 to limit the slider 5. The ramp 3 is located on the front side of the support platform 1. The highest point of the ramp 3 is not lower than the highest point of the fixed pulley 2. A recess 31 is provided along the long side of the top surface of the ramp. When the cable reel 10 is pushed up the ramp 3, the two sides of the cable reel 10 move along the recess 31 to prevent it from slipping. At least two through holes are opened on the side of the support platform 1. The two support platforms and the ramp are symmetrically arranged and a long rod 8 is inserted into the through holes to connect the two support platforms 1. The two ends of the long rod 8 are threaded. The support platform 1 can move within the thread range and is fixed and limited by nuts 9 set outside the through holes on both sides of the support platform 1.

[0012] In use, first adjust the distance between the two support platforms 1 to match the width of the cable reel 10 and tighten the nuts 9 to fix the two support platforms 1; then move the sliders 5 so that the distance between the two sliders 5 on the same support platform 1 matches the diameter of the cable reel 10, push the cable reel 10 from the ramp 3 onto the support platform 1, and support the cable reel 10 through the four fixed pulleys 3. When pulling the cable for laying, the cable reel 10 rotates, which drives the fixed pulleys 2 to rotate, so that the cable reel 10 rotates in place, so that the cable laying does not require too much space, reduces the friction generated when the cable reel 10 rotates, and saves manpower.
