Description

Technical Field

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

[0002] After the manufacturing process is completed, cables are usually stored in rolls. However, in actual cabling operations, it is necessary to unroll the rolls of cables in an orderly and smooth manner to meet construction requirements. Given the size and material characteristics of rolled cables, they often have considerable mass, and unrolling them manually is time-consuming and labor-intensive. Therefore, a cable unwinding device is required.

[0003] Currently, most traditional cable-laying devices employ a relatively basic design. Their core component is a freely rotating disc. During operation, the coiled cable is placed directly on this disc, and by pulling the cable end, external force causes the cable coil to rotate along with the disc, thus achieving the cable laying function. When the laying operation is complete or needs to be paused, the operator must manually operate the braking mechanism to apply braking force to the disc, stopping its rotation and thus halting the cable laying.

[0004] However, the drawback of this traditional cable-laying device is that its braking system relies entirely on manual start-stop, requiring at least two operators during construction: one to pull the cable and the other to focus on starting and stopping the braking mechanism. This manual intervention not only makes it difficult to precisely control the braking timing, easily leading to over-laying or interruption of the cable, but also significantly reduces construction efficiency. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a cable laying device that solves the problem of reduced construction efficiency caused by the need for manual start and stop of the braking structure after cable laying is completed in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a cable laying device, comprising: a rotating disk rotatably mounted on a base, a brake pad provided on the side of the rotating disk for use therewith, and a collar rotatably mounted on the side of the base; wherein, a cable is coiled and placed on the rotating disk, one end of the cable passes through and pulls the collar, the brake pad moves away from the rotating disk when the collar is pulled, and the brake pad resets and tightly abuts against the side of the rotating disk when the collar loses its pull.

[0007] Optionally, a shaft is fixed on the base, and the rotating disk is connected to the shaft via a bearing.

[0008] Optionally, there is a gap between the rotating disk and the base, and a plurality of first rollers are disposed in the gap. The first rollers are rotatably connected to the base, and the wheel surfaces of the first rollers abut against the rotating disk.

[0009] Optionally, the collar is fixed on the actuating shaft, the actuating shaft is fixed on the actuating plate and forms a fixed position, and the end of the actuating plate away from the actuating shaft is hinged to the side of the base and forms a hinge position.

[0010] Optionally, it also includes a tension spring, one end of which is hinged to the side of the base and forms a first tension position, and the other end of which is hinged to the actuating plate and forms a second tension position.

[0011] Optionally, the brake pad is fixed to the toggle plate.

[0012] Optionally, the side of the brake pad that abuts against the rotating disk is provided with a first friction part, and the side of the rotating disk is provided with a second friction part.

[0013] Optionally, a limiting plate is provided on the side of the actuating plate away from the tension spring for use therewith, and the limiting plate is fixed on the base.

[0014] Optionally, a plurality of second rollers are rotatably disposed on the collar, the cable passes through the collar and contacts the wheel surface of the second rollers, and the second rollers roll when the collar is pulled.

[0015] Optionally, it also includes a ball rotatably connected to the toggle plate.

[0016] The beneficial effects of this invention are as follows: By dynamically balancing the traction force and the tension spring force, the brake pads move away from the rotating disc when the collar is pulled, causing the rotating disc to rotate under the traction force to release the line. Simultaneously, when the collar loses traction, the brake pads return to their original position and tightly abut against the side of the rotating disc, rubbing against the side to stop its rotation and achieve braking. This realizes an automatic braking function, avoiding the need for manual start / stop of the braking structure in traditional line-releasing devices, thus improving line-releasing efficiency.

[0017] Meanwhile, in addition to the connection between the rotating disk and the base, this utility model also provides several first rollers. These first rollers provide support for the rotating disk to carry the coiled cable, avoiding the problem that the rotating disk is easily damaged due to uneven force or excessive local pressure under the action of the weight of the coiled cable and the centrifugal force generated by rotation.

[0018] Furthermore, this invention also incorporates a second roller on the collar, allowing the second roller to form a rolling contact at the contact point during cable traction. This contact method ensures that the direction of friction is tangential to the direction of cable movement, significantly reducing frictional resistance. Simultaneously, the rolling characteristics of the second roller effectively disperse contact pressure, preventing damage to the cable sheath caused by localized stress concentration.

[0029] 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.

[0030] As mentioned earlier, the drawback of traditional cable laying devices is that their braking system relies entirely on manual start and stop, requiring at least two operators during construction: one to pull the cable and the other to focus on starting and stopping the braking mechanism. This manual intervention not only makes it difficult to precisely control the braking timing, easily leading to over-laying or interruption of the cable, but also significantly reduces construction efficiency.

[0031] In view of this, the present invention provides a cable laying device that solves the above problems. The present invention solves the problem in the following way.

[0032] Example 1:

[0033] Please refer to the instruction manual appendix. Figures 1 to 7 As shown in the figure, this embodiment provides a cable unloading device, which includes at least a base 1, a rotating disk 2, a brake pad 3, and a collar 4. A shaft 11 is fixed on the base 1, and the rotating disk 2 is connected to the shaft 11 via bearings. The cable is coiled and placed on the rotating disk 2, passing through the shaft 11. In use, the operator pulls one end of the cable, and the cable and rotating disk 2 rotate around the shaft 11, thereby unloading the cable.

[0034] In this first embodiment, as Figure 1 or Figure 2 As shown, the brake pad 3 has a first friction part on the side near the rotating disk 2, and the rotating disk 2 has a second friction part on its side. Both the first and second friction parts are composed of several small particles. When the first and second friction parts come into contact with each other, friction is generated. This friction force overcomes the rotational force of the cable and the rotating disk 2, thereby stopping the rotation of the cable and the rotating disk 2, and thus achieving braking.

[0035] In this first embodiment, as Figure 1 or Figure 2As shown, brake pad 3 is fixed to actuation plate 42. One end of actuation plate 42 is hinged to base 1, forming hinge position 421, and the other end of actuation plate 42 is fixed to actuation shaft 41, forming fixed position 411. A collar 4 is fixed on actuation shaft 41. The traction end of the cable passes through collar 4. During traction, the outer sheath of the cable contacts the inner ring surface of collar 4, forming traction position. Using this traction position as a lever, collar 4, actuation shaft 41, and actuation plate 42 rotate around hinge position 421.

[0036] In this first embodiment, as Figure 1 or Figure 2 As shown, a tension spring 5 is also provided between the actuating plate 42 and the base 1. One end of the tension spring 5 is hinged to the side of the base 1, forming a first tension position 51, and the other end of the tension spring 5 is hinged to the actuating plate 42, forming a second tension position 52. When the operator pulls the cable, the collar 4, the actuating shaft 41, and the actuating plate 42 move around the hinge position 421 as shown. Figure 4 The rotation is shown in direction a. At this time, the brake pad 3 also rotates, moving away from the side of the rotating disk 2, and the braking effect disappears, allowing the rotating disk 2 to rotate and release the cable. At this time, the second tension position 52 also rotates with the actuating plate 42 and moves away from the first tension position 51, stretching the tension spring 5 and causing it to deform.

[0037] A limiting plate 6 is provided on the side of the actuating plate 42 away from the tension spring 5 to cooperate with it, and the limiting plate 6 is fixed on the base 1. When the actuating plate 42 abuts against the limiting plate 6, the distance between the second tension position 52 and the first tension position 51 reaches its maximum, and the tension spring 5 also deforms to its maximum.

[0038] After the cable laying is completed, the operator stops pulling the cable. Under the deformation of the tension spring 5, the second tension position 52 moves closer to the first tension position 51, causing the actuating plate 42 to return to its initial position. At this time, the brake pad 3 also rotates with the actuating plate 42, returning to the contact state with the surface of the rotating disk 2. At this time, under the frictional force of the first friction part and the second friction part, the rotational force of the rotating disk 2 is overcome, thereby stopping its rotation and completing the braking.

[0039] In this first embodiment, as Figures 6 to 7 As shown, a ball 7 is rotatably disposed on the bottom surface of the actuating plate 42. The ball 7 rolls during the rotation of the actuating plate 42, providing support for the actuating plate 42 in addition to the hinge position 421.

[0040] Example 2:

[0041] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figure 5As shown, in this second embodiment, a plurality of second rollers 43 are rotatably arranged on the collar 4. The cable passes through the collar 4 and contacts the wheel surface of the second rollers 43. The second rollers 43 roll when the collar 4 is pulled, thereby reducing the friction of the cable sheath when it is pulled.

[0042] Example 3:

[0043] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Three. For example... Figure 1 or Figure 2 As shown in this second embodiment, there is a gap between the rotating disk 2 and the base 1. Several first rollers 12 are arranged within this gap. The first rollers 12 are distributed along the rotation axis of the rotating disk 2 and are rotatably connected to the base 1. The wheel surfaces of the first rollers 12 abut against the rotating disk 2. When the rotating disk 2 rotates about the sleeve shaft 11 as its rotation axis, the first rollers 12 rotate accordingly, providing support for the rotating disk 2 while reducing friction. This allows the operator to rotate and unwind the coiled cable with less traction.

[0044] Therefore, in summary, the cable laying device and its various embodiments of this utility model have the following advantages compared with the prior art, including but not limited to:

[0045] This invention achieves automatic braking by dynamically balancing the traction force and the elastic force of the tension spring 5. When the collar 4 is pulled, the brake pad 3 moves away from the rotating disk 2, causing the rotating disk 2 to rotate under the traction force to release the line. Simultaneously, when the collar 4 loses traction, the brake pad 3 returns to its original position and tightly abuts against the side of the rotating disk 2, rubbing against the side to stop its rotation and thus achieving braking. This function avoids the need for manual start / stop of the braking structure required in traditional line-releasing devices, improving line-releasing efficiency.

[0046] Meanwhile, in addition to the connection of the sleeve shaft 11 between the rotating disk 2 and the base 1, this utility model also provides a number of first rollers 12. These first rollers 12 provide support for the rotating disk 2 to carry the coiled cable, thus avoiding the problem that the rotating disk 2 is easily damaged due to uneven force or excessive local pressure under the action of the weight of the coiled cable and the centrifugal force generated by rotation.

[0047] Furthermore, this invention also includes a second roller 43 on the collar 4, which allows the second roller 43 to form rolling contact at the contact point during the cable traction process of the collar 4. This contact method ensures that the direction of friction is tangential to the direction of cable movement, greatly reducing frictional resistance. At the same time, the rolling characteristics of the second roller 43 effectively disperse the contact pressure, avoiding damage to the cable sheath caused by localized stress concentration.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
