Description

Technical Field

[0001] This utility model relates to the technical field of cable installation equipment, specifically to a cable laying device. Background Technology

[0002] In cable laying operations in fields such as power engineering and construction engineering, cables are typically stored and transported wrapped in cylindrical cable reels. The cable laying device, as a core auxiliary equipment in cable laying, primarily functions to support the cable reel and guide the cable out smoothly, directly impacting the efficiency, safety, and material loss rate of cable laying. With the acceleration of power construction and urbanization, cable laying scenarios are becoming increasingly complex, involving diverse cable specifications (such as diameter and length)—from low-voltage small-diameter cables to high-voltage large-diameter cables, from short-distance indoor laying to long-distance outdoor installation. The requirements for cable reel specifications also change accordingly, with common cable reel supports exhibiting significant differences in diameter and length.

[0003] In actual construction, the cable laying device must first be adapted to the cable reel support before the laying operation can begin. Insufficient compatibility can easily lead to the cable reel support shifting or tipping over, or excessive resistance during laying can cause cable wear or jamming. If the operation process is complicated, it will increase the construction preparation time and labor costs.

[0004] Existing cable laying devices mostly use fixed-size support structures, and the distance between the rollers and the support mechanism cannot be flexibly adjusted. They can only be adapted to a single or a few specifications of cable reel supports. When faced with cable reel supports of different diameters and lengths, the corresponding cable laying device must be replaced. This not only increases the equipment procurement cost but also requires a lot of time for equipment disassembly and replacement, resulting in low construction efficiency and difficulty in meeting diverse cable laying needs. Utility Model Content

[0005] This utility model provides a cable laying device that can solve the problem in the prior art where the fixed-size support structure cannot flexibly adjust the distance between the rollers and the support mechanism, and can only adapt to a single or a few specifications of cable roll brackets.

[0006] A cable laying device includes a support mechanism and a crossbar. The support mechanism comprises two sets, each including a support frame, a guide plate, a first roller, a insertion rod, and a second roller. The support frame has a groove, and the guide plate is fixedly installed in the groove at an angle. The first roller is horizontally rotatably installed in the groove and located near the guide plate. The top of the support frame has a slot communicating with the groove. Several slots are arranged at equal intervals along the transverse direction. The insertion rod is slidably connected to the slot, and the second roller is rotatably connected to the insertion rod. The support frame is slidably connected to the crossbar.

[0007] According to one embodiment of this utility model, the support mechanism further includes a sleeve, which is horizontally fixedly connected to the support frame and slidably connected to the crossbar. The support mechanism also includes a limiting rod; the side of the crossbar has several through holes arranged in a rectangular array at equal intervals; the sleeve has a limiting hole; and the limiting rod passes through the limiting hole and the corresponding through hole. The limiting rod has an external thread on its outer side, and the limiting hole has an internal thread that engages with the threaded connection of the limiting rod. The outer side of the crossbar has graduations.

[0008] According to one embodiment of this utility model, the side of the support frame is provided with a sliding groove communicating with the slot. A baffle is slidably disposed in the sliding groove, one end of the baffle being located above the insertion rod, and the other end of the baffle being located outside the groove opening. A horizontal guide rod is fixedly disposed in the sliding groove, and the baffle has a guide hole that slidably engages with the guide rod. A spring is wound around the outside of the guide rod, one end of the spring abutting against the baffle, and the other end of the spring being fixedly connected to the end of the guide rod away from the slot. An inclined surface is provided on the top of the baffle at the end above the insertion rod. An anti-slip protrusion is provided on the end of the baffle outside the groove opening.

[0009] The advantages of this utility model compared to the prior art are: With the cooperation of multiple slots and plugs, the distance between the first and second rollers can be flexibly adjusted according to the diameter of the cable reel bracket. By sliding the support frame along the crossbar, it can also be adapted to cable reel brackets of different lengths. This completely solves the problem that traditional cable laying devices are difficult to adapt to various specifications of cable reel brackets due to their fixed size. It can meet the needs of different cable laying scenarios without frequent equipment replacement, significantly improving the versatility of the equipment and reducing construction costs.

Detailed Implementation

[0016] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0017] like Figures 1 to 4 As shown, a cable laying device includes a support mechanism 1 and a crossbar 2. The support mechanism 1 is provided in two sets. The support mechanism 1 includes a support frame 3, a guide plate 4, a first roller 5, an insertion rod 6, and a second roller 7. The support frame 3 has a groove 8. The guide plate 4 is fixedly installed in the groove 8 in an inclined state. The first roller 5 is rotatably installed in the groove 8 in a horizontal state and is located at one end close to the guide plate 4. The top of the support frame 3 has a slot 9 that communicates with the groove 8. Several slots 9 are provided and are arranged at equal intervals in the transverse direction. The insertion rod 6 is slidably connected to the slot 9. The second roller 7 is rotatably connected to the insertion rod 6. The support frame 3 is slidably connected to the crossbar 2.

[0018] Two sets of support mechanisms 1 provide support and guidance for the cable reel brackets. Since different specifications of cable reel brackets vary in diameter and length, workers can first select appropriate slots 9 on the top of the support frame 3 according to the diameter of the cable reel bracket and insert the insertion rod 6. The slots 9 are arranged at equal intervals along the horizontal direction, allowing for flexible adjustment of the installation position of the insertion rod 6. The second roller 7, which rotates in conjunction with the insertion rod 6, will synchronously change its horizontal spacing with the insertion rod 6, ultimately creating a support space on the support mechanism 1 between the first roller 5 and the second roller 7 to accommodate different diameters, ensuring the cable reel brackets can be placed stably without shifting. Subsequently, workers can utilize the sliding fit between the support frame 3 and the crossbar 2 to adjust the spacing of the two sets of support mechanisms 1 along the crossbar 2 to further accommodate cable reel brackets of different lengths.

[0019] During the cable laying stage, workers roll the cable reel bracket at both ends into the space between the first roller 5 and the second roller 7 along the inclined guide plates 4 within the grooves 8 of the support frame 3. The inclined design of the guide plates 4 not only reduces the difficulty of placing the cable reel bracket but also prevents damage caused by hard collisions between the bracket and the support frame 3. When the cable is pulled out, as the cable is gradually removed from the cable reel bracket, the cable reel bracket will rotate naturally under the combined support of the first roller 5 and the second roller 7. This converts the sliding friction of the cable reel bracket into rolling friction, significantly reducing the resistance during the bracket's rotation. This effectively prevents jamming during the cable laying process, ensuring that the cable can be pulled out continuously and smoothly, and guaranteeing the efficient progress of the cable laying operation.

[0020] With the cooperation of the slots 9 and the rods 6, the distance between the first roller 5 and the second roller 7 can be flexibly adjusted according to the diameter of the cable reel bracket. By sliding the support frame 3 along the crossbar 2, it can also be adapted to cable reel brackets of different lengths. This completely solves the problem that traditional cable laying devices are difficult to adapt to various specifications of cable reel brackets due to their fixed size. It can meet the needs of different cable laying scenarios without frequent equipment replacement, significantly improving the versatility of the equipment and reducing construction costs.

[0021] According to one embodiment of the present invention, the support mechanism 1 further includes a sleeve 10, which is horizontally fixedly connected to the support frame 3 and slidably connected to the crossbar 2. The support mechanism 1 also includes a limiting rod 11. The side of the crossbar 2 has several through holes 12 arranged in a rectangular array at equal intervals. The sleeve 10 has limiting holes 13, and the limiting rod 11 passes through the limiting hole 13 and the corresponding through hole 12. The limiting rod 11 has an external thread on its outer side, and the limiting hole 13 has an internal thread that engages with the limiting rod 11. The outer side of the crossbar 2 has graduations 14.

[0022] When workers need to adjust the spacing between the two sets of support mechanisms 1 along the crossbar 2 to accommodate cable reel supports of different lengths, the sleeve 10 of the support mechanism 1 is slidably connected to the crossbar 2, allowing the support frame 3 to be directly pushed to cause the sleeve 10 to slide laterally along the crossbar 2. At this time, workers can visually read the real-time spacing between the two sets of support mechanisms 1 through the scale 14 on the outer side of the crossbar 2, accurately adjusting it to a value matching the length of the cable reel support without the need for additional measuring tools, thus avoiding spacing deviations caused by traditional experience-based adjustments.

[0023] Once the spacing is adjusted to the target position, stop sliding the sleeve 10, aligning the limiting hole 13 on the sleeve 10 with the corresponding through hole 12 on the side of the crossbar 2. The side of the crossbar 2 has several through holes 12 arranged in a rectangular array at equal intervals, ensuring that there are suitable through holes 12 for different adjustment positions. Then, insert the limiting rod 11 with external threads through the limiting hole 13 and the corresponding through hole 12. Since the limiting hole 13 has an internal thread that engages with the threaded limit rod 11, rotating the limiting rod 11 will achieve threaded fixation between the limiting rod 11 and the sleeve 10, thereby tightly locking the sleeve 10 and the crossbar 2, preventing the support mechanism 1 from sliding due to external forces such as vibration and cable pulling during the cable laying operation, and ensuring that the support spacing remains stable.

[0024] According to one embodiment of the present invention, the support frame 3 has a sliding groove 15 on its side that communicates with the slot 9. A baffle 16 is slidably disposed in the sliding groove 15, with one end of the baffle 16 located above the insertion rod 6 and the other end of the baffle 16 located outside the groove opening of the sliding groove 15. A horizontal guide rod 17 is fixedly disposed in the sliding groove 15, and the baffle 16 has a guide hole that slidably engages with the guide rod 17. A spring 18 is wound around the outside of the guide rod 17, with one end of the spring 18 abutting against the baffle 16 and the other end of the spring 18 fixedly connected to the end of the guide rod 17 away from the slot 9. An inclined surface 19 is provided on the top of the baffle 16 at the end above the insertion rod 6. An anti-slip protrusion 20 is provided on the end of the baffle 16 outside the groove opening of the sliding groove 15.

[0025] When installing the insertion rod 6, the operator first needs to push the end of the baffle 16 outside the groove 15, causing the baffle 16 to slide away from the slot 9 along the guide rod 17 inside the groove 15. The baffle 16 has a guide hole that slides with the guide rod 17 to ensure a smooth sliding process. At this time, the spring 18 wrapped around the outside of the guide rod 17 is compressed, and the end of the baffle 16 above the insertion rod 6 leaves the area of ​​the slot 9. The slot 9 is in an open state, and the operator can smoothly insert the insertion rod 6 into the target slot 9.

[0026] After inserting the rod 6, release the force applied to the baffle 16. The compressed spring 18 will generate a restoring force, pushing the baffle 16 along the guide rod 17 towards the slot 9 until the end of the baffle 16 above the rod 6 abuts against the top of the rod 6, forming a longitudinal limit on the rod 6 and preventing it from coming out of the slot 9 due to vibration or external force during the wire laying operation. Furthermore, the top of the baffle 16 above the rod 6 has an inclined surface 19. To install the rod 6, the operator only needs to press down on the rod 6, and the bottom of the rod 6 will press against the baffle 16 along the inclined surface 19, causing the baffle 16 to automatically slide outwards from the groove 15 and compress the spring 18. This eliminates the need for manual pushing of the baffle 16, making the operation more convenient. Simultaneously, the end of the baffle 16 outside the slot has an anti-slip protrusion 20, which increases the friction between the hand and the baffle 16, preventing slippage during pulling.

[0027] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
