Description

Technical Field

[0001] This utility model relates to the field of cable winding and unwinding technology, and in particular to a microgrid cable winding and unwinding auxiliary device. Background Technology

[0002] In the construction, operation, maintenance, and upgrading of microgrids, cable laying and retrieval are frequent and critical operations. These operations typically involve a large number of cable reels of different specifications, sizes, and weights, and their efficient and safe handling directly affects project progress and personnel safety.

[0003] Currently, cable reels are typically supported on construction sites using temporary wooden blocks, simple supports, or large machinery (such as cranes). These existing technologies have significant shortcomings: they cannot flexibly adjust the spacing, are difficult to match reels of different specifications, leading to uneven or even jammed reel rotation, and exhibit poor stability. Under the continuous traction and vibration generated by rapid cable winding and unwinding, reels are prone to displacement or overturning, posing serious safety hazards. Relying on large machinery is costly, inflexible, and unsuitable for space-constrained or rapid-response work scenarios.

[0004] In response to this technical problem, this application proposes a microgrid cable retraction and deployment auxiliary device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies, such as inability to adapt to multiple cable reels and insufficient stability, resulting in low operating efficiency and safety hazards. Therefore, a microgrid cable winding and unwinding auxiliary device is proposed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A microgrid cable reeling and unloading auxiliary device includes two support frames. Each support frame has a through groove on its top side. A fixed support roller is rotatably connected to the front end of the inner wall of the through groove, and multiple positioning grooves are provided at the rear end. Movable support rollers are engaged with the inner walls of the positioning grooves to collectively support the cable reel. One support frame is connected to a sleeve rod, and the other is connected to a sliding rod. The sliding rod is slidably inserted into the sleeve rod, and both are provided with a first locking mechanism to fix the distance between the two support frames. Each support frame has a slot at its bottom, into which a plug fixed to a ground anchor is inserted. A second locking mechanism is provided to lock the plug within the slot.

[0007] Furthermore, the first locking mechanism includes a plurality of positioning holes axially formed on the outer sides of the sleeve and the slide, and positioning pins that can be inserted into the positioning holes for selectively fixing the relative positions of the sleeve and the slide.

[0008] Furthermore, the second locking mechanism includes a limiting rod that passes through the support frame and through the insert, and a threaded sleeve that is threadedly connected to the limiting rod, for pressing and locking the insert by tightening the threaded sleeve.

[0009] Furthermore, the two ends of the limiting rod are threaded in opposite directions to allow the screw sleeve to be tightened simultaneously from both sides.

[0010] Furthermore, the movable support roller can be selectively engaged in the positioning groove at different positions to accommodate coils of different diameters.

[0011] Furthermore, multiple fixing plates are fixedly connected to the outer side of the ground anchor along the axial direction to enhance the anchoring force in the ground.

[0012] Furthermore, the bottom of the support frame is provided with foot pads to provide stable support in the non-anchored state.

[0013] Furthermore, the front end of the support frame is beveled, and its surface is provided with anti-slip grooves to facilitate the winding of the thread and prevent slippage.

[0014] This utility model has the following beneficial effects: 1. This utility model allows for quick and flexible adjustment to accommodate reels of different sizes and specifications, greatly expanding its application range. Through an innovative adaptive adjustment mechanism, operators can quickly match the diameter and width of the reel without the need for any special tools.

[0015] 2. In this utility model, by providing stable and reliable anchoring support and effective anti-slip measures, the displacement and overturning of the device during operation are effectively prevented, ensuring operational safety. Even under the continuous vibration and impact load generated by the rapid winding and unwinding of the cable, it can still maintain excellent stability, completely solving the safety hazards of easy slippage and overturning of traditional support devices.

Detailed Implementation

[0018] 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.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a microgrid cable winding and unwinding auxiliary device, comprising two support frames 1. A through groove 2 is provided on the top side of the support frame 1. A fixed support roller 3 is rotatably connected to the front end of the inner wall of the through groove 2, and a plurality of positioning grooves 4 are provided at the rear end. A movable support roller 5 is engaged with the inner wall of the positioning groove 4 to jointly support the cable reel 6. The fixed support roller 3 and the movable support roller 5 with adjustable position form a flexible support structure for the cable reel 6. This structure allows the cable reel 6 to rotate smoothly through the rotation of the rollers when winding and unwinding the cable. At the same time, by engaging the movable support roller 5 into the positioning grooves 4 of different depths, it can adapt to cable reels 6 of different diameters, effectively improving the versatility of the device. One support frame 1 is connected to a sleeve rod 7, and the other is connected to a sliding rod 8. The sliding rod 8 is slidably inserted into the sleeve rod 7, and both are provided with a first locking mechanism to fix the distance between the two support frames 1. The bottom of the support frame 1 is provided with a slot 12, in which a plug 13 fixed to the ground anchor 16 is inserted, and a second locking mechanism is provided to lock the plug 13 into the slot 12. The first locking mechanism includes multiple positioning holes 9 opened axially on the outside of the sleeve rod 7 and the sliding rod 8, and positioning pins 10 that can be inserted into the positioning holes 9 to selectively fix the relative position of the sleeve rod 7 and the sliding rod 8. The distance between the two support frames 1 is adjusted by the sliding cooperation of the sleeve rod 7 and the sliding rod 8, and then fixed by the first locking mechanism composed of the positioning holes 9 and the positioning pins 10, so that the device can flexibly match the coils 6 of different widths and ensure the stability of the coils 6 when rotating. The second locking mechanism includes a limiting rod 14 that passes through the support frame 1 and through the insert 13, and a threaded sleeve 15 that is threadedly connected to the limiting rod 14, for pressing and locking the insert 13 by tightening the threaded sleeve 15. The design of the reverse threads at both ends allows the tightening of the threaded sleeve 15 to generate a bidirectional locking force, thereby firmly fixing the insert 13 in the slot 12. Reference Figures 1-3 The limiting rod 14 has threads in opposite directions at both ends to allow the screw sleeve 15 to be tightened simultaneously from both sides; the movable support roller 5 can be selectively inserted into the positioning groove 4 at different positions to accommodate spools 6 of different diameters; multiple fixing plates 17 are fixedly connected axially to the outside of the ground anchor 16 to enhance the anchoring force in the ground; the bottom of the support frame 1 is provided with foot pads 18 to provide stable support in the non-anchored state; the front end of the support frame 1 is beveled and its surface is provided with anti-slip grooves 11 to facilitate the spool 6 rolling on and prevent slippage; The ground anchor 16 and its outer fixing plate 17 can penetrate deep into the ground to form a reliable anchoring effect, preventing the device from shifting during cable winding and unwinding. When used on hardened ground, the foot pads 18 at the bottom of the support frame 1 can provide a stable support foundation, while the beveled surface and anti-slip groove 11 at the front end of the support frame 1 form a guiding and anti-slip structure, which not only facilitates the cable reel 6 to roll onto the support frame 1, but also prevents the operator from slipping when stepping on it, thereby fully ensuring operational safety and efficiency.

[0020] Working principle: In use, firstly, adjust the distance between the two support frames 1 according to the width of the spool 6: the operator holds the support frame 1 and pulls it to the sides or pushes it inward, so that the slide bar 8 slides axially within the sleeve 7. When it reaches the position that matches the width of the spool 6, insert the positioning pin 10 into the positioning hole 9 at the corresponding position, and fix the distance of the support frame 1 through the first locking mechanism; then, adjust the support position of the movable support roller 5 according to the diameter of the spool 6, take it out of the current positioning groove 4, and insert it into the positioning groove 4 of the corresponding depth, forming a support curved surface suitable for the diameter of the spool 6 with the fixed support roller 3; after completing the above adjustment, push the spool 6 onto the support frame 1 along the beveled surface at the front end of the support frame 1, so that its outer side rests stably on the support surface formed by the fixed support roller 3 and the movable support roller 5. At this time, the anti-slip groove 11 on the beveled surface can not only assist the spool 6 to roll smoothly, but also prevent the operator from slipping when stepping on it; When working on soft ground, insert the plug 13 into the slot 12 at the bottom of the support frame 1, so that the limiting rod 14 passes through the plug 13. By tightening the threaded sleeves 15 with reverse threads at both ends, the plug 13 is firmly fixed by the bidirectional locking force generated by the second locking mechanism. Then, the ground anchor 16 is hammered into the ground. The fixing plate 17 on its outer side can significantly enhance the anchoring force and effectively prevent the device from shifting during cable laying and winding. When used on hard ground, there is no need to install the ground anchor 16. The foot pads 18 at the bottom of the support frame 1 can be used directly to provide stable support. During the cable laying and winding process of the reel 6, the fixed support roller 3 and the movable support roller 5 rotate synchronously to form a flexible support structure, which not only ensures the smooth rotation of the reel 6, but also avoids wear on the side of the reel 6. The whole device achieves adaptive support for reels 6 of different specifications through multiple adjustment and fixing mechanisms, which significantly improves the efficiency and safety of microgrid cable laying and winding operations.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
