Description

Technical Field

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

[0002] A cable puller is an auxiliary tool that helps cables pass through conduits and cable trays. It is usually made of high-strength steel wire or fiber material and has a guide head at the front end. When laying cables in conduits, the cable puller is first passed through the conduit, and then the cable is connected to the cable puller. By pulling the cable puller, the cable can be easily guided into the conduit, reducing friction between the cable and the inner wall of the conduit and protecting the cable sheath from damage.

[0003] During the cable pulling process, the cable may pull back due to external force or its own weight. Traditional cable pullers are often designed with the pulling function in mind, neglecting the development of anti-pull-back function.

[0004] The newly designed cable routing device features an improved puller design with an added anti-reverse function, and the anti-reverse direction can be adaptively adjusted according to the direction of wire pulling. Utility Model Content

[0005] (a) Technical issues The present invention aims to at least solve the problem of retraction that occurs when manually pulling the steel wire in the prior art.

[0006] (II) Technical Content This solution provides a cable wiring device, achieved through the following specific technical means: including... A circular spool contains a traction rope wound inside, with the front end of the traction rope passing through a fixed outlet tube on the outer wall of the circular spool. An anti-reverse assembly is provided on the outlet pipe. The anti-reverse assembly includes a connecting sleeve fixedly sleeved on the outlet pipe, and mounting brackets extending to the front of the outlet pipe port on both sides of the connecting sleeve. The eccentric shafts on the first eccentric anti-reverse wheel and the second eccentric anti-reverse wheel are rotatably mounted on the mounting frame and symmetrically located on both sides of the front end of the outlet pipe. The first movable shaft and the second movable shaft are also rotatably mounted on the mounting frame. A convex shaft is fixed at another eccentric position of the first eccentric anti-reverse wheel, and a convex shaft is fixed at another eccentric position of the second eccentric anti-reverse wheel. A spring is connected between the convex shaft and the movable shaft that is close to the first eccentric anti-reverse wheel, and a spring is connected between the convex shaft and the movable shaft that is close to the second eccentric anti-reverse wheel. The rebound tension of the first spring and the second spring provides the initial clamping force of the first eccentric anti-reverse wheel and the second eccentric anti-reverse wheel on the traction rope. When the traction rope is pulled outward, the anti-reverse component is used to limit the traction rope from retracting; when the traction rope is wound up, the anti-reverse component is used to limit the traction rope from being pulled outward.

[0007] Preferred technical solution 2: A rotating sleeve is rotatably sleeved on the eccentric anti-reverse wheel 1 and the eccentric anti-reverse wheel 2, and an anti-slip pad layer is wrapped on the outside of the rotating sleeve.

[0008] Preferred technical solution three: At the same time, anti-retraction force adjustment components are also provided on the first and second movable shafts to adjust the initial tension of the first and second springs.

[0009] Preferred technical solution four: Threaded holes are provided on the side walls of both the first and second movable shafts. The anti-reverse force adjustment component includes a threaded rod and a connector rotatably mounted on the end of the threaded rod. The connector replaces the corresponding first and second movable shafts and connects to the corresponding first and second springs. The threaded rod passes through the corresponding threaded hole.

[0010] (III) Technical Effects The above structure gives this solution the following advantages: 1. Two-way anti-reverse function: Through the unique design of eccentric anti-reverse wheel one and eccentric anti-reverse wheel two, the two-way anti-reverse function of the traction rope is realized. This design breaks through the limitation of traditional cable pullers that can only prevent retraction in one direction; when it is necessary to pull the traction rope outward, the anti-reverse component can prevent it from retracting; when it is necessary to wind up the traction rope, the anti-reverse component can prevent it from being pulled outward, which greatly improves the efficiency and flexibility of cable laying. 2. The initial clamping force is provided by the rebound tension of spring one and spring two, and the anti-reverse wheel generates different friction forces in different directions through the cooperation of the eccentric shaft and the cam shaft, thereby realizing the automatic switching of the anti-reverse direction. This design is not only simple in structure, but also easy to operate. The anti-reverse direction can be changed simply by flipping the eccentric anti-reverse wheel, without the need for a complicated adjustment process. 3. It adopts a purely mechanical structure design, which does not require electronic components and complex control systems, thus reducing manufacturing costs and maintenance difficulty; 4. It can adapt to various specifications and materials of traction ropes. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-2 The cable wiring device includes a ring-shaped drum 1 and an anti-reverse assembly 3 installed on the ring-shaped drum 1, wherein: the ring-shaped drum 1 has a traction rope 2 wound and housed in it, the front end of the traction rope 2 passes through a fixed outlet pipe 13 through the outer wall of the ring-shaped drum 1, and a traction head for connecting wires is connected to the outer end of the traction rope 2 (using an existing structure, so it will not be described in detail in the text). The anti-reverse component 3 is installed on the outlet pipe 13. The anti-reverse component 3 can change its anti-reverse direction according to operational needs. That is, when the traction rope 2 is pulled outward, the anti-reverse component 3 is used to limit the retraction of the traction rope 2 (e.g., Figure 2 When winding the traction rope 2, the anti-reverse component 3 is used to limit the traction rope 2 from being pulled outward (e.g., Figure 1 ); Adaptable to various cabling scenarios: In actual cable cabling, it is often necessary to perform wire pulling operations in different directions, such as horizontal and vertical wire pulling. The bidirectional anti-backward function of this device can adapt to the needs of various cabling scenarios. Whether pulling the external traction rope 2 or reeling in the traction rope 2, it can provide reliable anti-backward protection to ensure the smooth progress of cabling work.

[0016] In one set of embodiments Please see Figure 1 , Figure 5The anti-reverse assembly 3 includes a connecting sleeve 31 fixedly sleeved on the outlet pipe 13, and mounting brackets 32 extending to the front of the outlet pipe 13 on both sides of the connecting sleeve 31; an eccentric anti-reverse wheel 33 and an eccentric anti-reverse wheel 34 are rotatably mounted between the front ends of the two sets of mounting brackets 32, and the eccentric anti-reverse wheel 33 and the eccentric anti-reverse wheel 34 are symmetrically located on both sides of the front port of the outlet pipe 13. Specifically, the eccentric shafts on eccentric anti-reverse wheel 33 and eccentric shafts on eccentric anti-reverse wheel 34 are rotatably mounted on mounting bracket 32. Movable shaft 35 and movable shaft 36 are also rotatably mounted on mounting bracket 32. Movable shaft 35 and movable shaft 36 are located between the eccentric shafts on eccentric anti-reverse wheel 33 and eccentric shafts on eccentric anti-reverse wheel 34. A convex shaft 331 is fixed at another eccentric position on eccentric anti-reverse wheel 33, and a convex shaft 341 is fixed at another eccentric position on eccentric anti-reverse wheel 34. A spring connects convex shaft 331 and movable shaft 35, which is close to eccentric anti-reverse wheel 33. 37. At the same time, a spring 38 is connected between the second cam shaft 341 and the second movable shaft 36 which is close to the second eccentric anti-reverse wheel 34 (the first spring 37 and the second spring 38 are always in a stretched state). The rebound tension of the first spring 37 and the second spring 38 makes the distance between the first cam shaft 331, the second cam shaft 341 and the central axis of the outlet tube 13 smaller than the distance between the eccentric shaft on the first eccentric anti-reverse wheel 33 and the eccentric shaft on the second eccentric anti-reverse wheel 34 and the central axis of the outlet tube 13. The rebound tension of the first spring 37 and the second spring 38 provides the initial clamping force of the first eccentric anti-reverse wheel 33 and the second eccentric anti-reverse wheel 34 on the traction rope 2. When the first cam shaft 331 and the second cam shaft 341 are located behind the first movable shaft 35 and the second movable shaft 36, the clamp formed by the first eccentric anti-reverse wheel 33 and the second eccentric anti-reverse wheel 34 will gradually shrink due to friction when the traction rope 2 is pulled outward, thus achieving the anti-reverse function in this direction. When the rope is rolled inward, the clamp increases to ensure smooth inward rolling. When the first cam shaft 331 and the second cam shaft 341 are located in front of the first movable shaft 35 and the second movable shaft 36, the clamp formed by the first eccentric anti-reverse wheel 33 and the second eccentric anti-reverse wheel 34 will gradually shrink due to friction when the traction rope 2 is rolled inward, thus achieving the anti-reverse function in this direction. When pulling outward, the clamp increases to ensure smooth pulling outward. When the anti-reverse direction needs to be adjusted: flip the eccentric anti-reverse wheel 33 and the eccentric anti-reverse wheel 34 forward or backward. When flipping, the spring 37 and the spring 38 rotate with the movable shaft 35 and the movable shaft 36 to the front or rear of the movable shaft 35 and the movable shaft 36 to realize the anti-reverse direction change (for convenient flipping operation, the cam shaft 331 and the cam shaft 341 can be further extended to make them used as handles for flipping operation).

[0017] In one set of embodiments Please see Figure 5A rotating sleeve 4 is rotatably sleeved on the eccentric anti-reverse wheel 33 and the eccentric anti-reverse wheel 34, and an anti-slip pad layer 41 is wrapped on the outside of the rotating sleeve 4. By having the anti-slip pad 41 contact the traction rope 2, the combination of the swivel 4 and the anti-slip pad 41 provides sufficient friction while preventing damage to the traction rope 2 from excessive closure of the clamp. When the external force of retraction is too large, the swivel 4 can rotate to relieve the force, thus extending the service life of the traction rope 2 and reducing the cost of use.

[0018] In one set of embodiments Please see Figure 3 Meanwhile, anti-reverse force adjustment components 5 are also provided on movable shaft 1 35 and movable shaft 2 36 to adjust the initial tension of spring 1 37 and spring 2 38, specifically: Threaded holes are provided on the side walls of movable shaft 35 and movable shaft 36. The anti-retraction force adjustment component 5 includes a threaded rod 52 and a connector 51 rotatably mounted on the end of the threaded rod 52. The connector 51 replaces the corresponding movable shaft 35 and movable shaft 36 and connects to the corresponding spring 37 and spring 38. The threaded rod 52 passes through the corresponding threaded hole. The initial tension of spring 37 and spring 38 can be adjusted by rotating the threaded rod 52. Furthermore, a scale marking can be set on the threaded rod 52 to allow users to accurately understand the current anti-reverse force.

[0019] In one set of embodiments Please see Figure 2 , Figure 4 The annular spool 1 consists of a spool 11 and an annular cover 12 mounted on the spool 11. The annular cover 12 is rotatably connected to the spool 11. (To make the rotation between the annular cover 12 and the spool 11 smoother, a bearing structure can be installed between them. The bearing can be a deep groove ball bearing or an angular contact ball bearing, and the appropriate selection should be made according to the load and usage requirements of the device. When adding a bearing, a seal needs to be installed on the outside of the bearing to prevent dust and debris from entering the bearing and affecting its service life.) The outlet tube 13 is fixed through and fixed to the annular cover 12. The inner end of the traction rope 2 is fixed to the spool 11 and wound and stored on the spool 11. Multiple sets of rotating wheels 14 are installed circumferentially inside the annular cover 12. The outer layer of the traction rope 2 in the wound state contacts the rotating wheels 14. Utilizing the rotatable feature of the rotating wheels 14, the friction between the traction rope 2 and the inner wall of the protective cover is reduced. The position and density of the rotating wheels 14 are reasonably arranged according to the winding path and stress of the traction rope 2. The number of rotating wheels 14 is increased in the parts where the traction rope 2 is likely to contact the inner wall of the protective cover, ensuring that the traction rope 2 can pass smoothly during the winding process. At the same time, the material of the rotating wheels 14 should be selected to have a low coefficient of friction and good wear resistance to further reduce friction and wear.

[0020] During use, this solution requires daily maintenance of each component according to the established maintenance plan to ensure its working condition.
