Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, and in particular to a tensioning device for wire and cable laying. Background Technology

[0002] Wires and cables are important materials used for power transmission and signal transmission, and are widely used in electronic equipment, communication networks and other fields. The tensioning device in wire and cable laying is a special device used to tighten the cable during the laying process. Its purpose is to ensure that the cable maintains a certain tension during laying to prevent the cable from being damaged or excessively bent, and to ensure the safety and normal use of the cable.

[0003] Existing wire and cable tensioning devices typically complete the tightening of the wire and cable by simply winding the cable around the outside of the take-up roller. However, the wire and cable are not always wound in a flat state around the outside of the take-up roller. Some parts of the cable are bent, making it difficult to tighten. In addition, existing wire and cable winding devices generally concentrate the wire and cable in the middle section of the take-up roller during tightening, which causes the middle position of the take-up roller to bulge out, and the wound wire and cable is prone to slipping and loosening.

[0004] Therefore, in response to the problem that the above-mentioned wire and cable tightening devices cannot adapt to the tightening requirements of bent cables and that the winding area is too concentrated, this utility model designs the conductor tube as an elastic support by setting a mechanism component. When winding a bent wire or cable, the conductor tube can adapt to the bending force of the cable through the up and down displacement trajectory process. At the same time, the conductor tube plays an auxiliary traction role. Furthermore, the movable design of the conductor tube can also wind the wire or cable to different height positions of the winding roller, thereby avoiding the phenomenon that the stress of the wire or cable is concentrated in the middle position of the winding roller when winding, which makes it easy to fall off after winding. Utility Model Content

[0005] To overcome the problem that a common type of tensioning device for wire and cable installation cannot adapt to the tightening requirements of bent cables, and that the winding area is too concentrated.

[0006] The technical solution of this utility model is as follows: a tensioning device for laying wires and cables, including a support frame, a take-up roller, and a conductor tube. The support frame is configured with a "U"-shaped structure, and the take-up roller is rotatably installed inside the support frame. The conductor tube is located on the side of the take-up roller. An annular wire-locking groove is opened on the outer wall of the side of the take-up roller at the middle section. The conductor tube is configured as a horizontally placed funnel shape, and the smaller opening of the conductor tube faces the take-up roller. A tensioning control mechanism is provided above the support frame, an auxiliary traction mechanism is provided on the outside of the conductor tube, and a positioning support mechanism is provided on the side of the support frame.

[0007] Preferably, the tensioning control mechanism includes a positioning support frame, a drive motor, a drive gear, a driven gear, and a transmission shaft. The positioning support frame is fixedly installed on the top outer wall of the support frame. The positioning support frame is configured as an "n" shape, and the drive motor is fixedly installed on the top outer wall of the positioning support frame. The output end of the drive motor is connected to the top outer wall of the drive gear. The driven gear is meshed with the side of the drive gear. The transmission shaft is fixedly installed on the bottom outer wall of the driven gear located at the shaft center. The bottom end of the transmission shaft passes through the top outer wall of the support frame and is rotatably installed with the bottom inner wall of the support frame. The take-up roller is fixedly installed through and outside the transmission shaft.

[0008] Preferably, both the driving gear and the driven gear are rotatably mounted to the top outer wall of the support frame, and the diameter of the driving gear is larger than the diameter of the driven gear.

[0009] Preferably, the auxiliary traction mechanism includes a positioning support bar, a limiting cylinder, a limiting piston rod, and a support spring. The top and bottom inner walls of the support frame are symmetrically provided with positioning support bars. The positioning support bar located at the bottom position has a limiting cylinder embedded inside. The limiting piston rod is slidably installed inside the limiting cylinder. A support spring is connected between the bottom outer wall of the limiting piston rod and the bottom inner wall of the limiting cylinder. The protruding end of the limiting piston rod is located above the limiting cylinder, and the protruding end of the limiting piston rod is connected to the bottom outer wall of the conduit.

[0010] Preferably, the limiting cylinder is filled with damping fluid, and the outer wall of the top of the limiting piston rod located at the piston disc position has a cylindrical hole that allows the damping fluid to flow through.

[0011] Preferably, the positioning support mechanism includes a support base, an auxiliary mounting plate, and a reinforcing support plate. The support base is symmetrically arranged on both outer walls of the support frame at the bottom position. The auxiliary mounting plate is fixedly installed on the top outer wall of the support base. The reinforcing support plate is symmetrically arranged on the top outer wall of the auxiliary mounting plate, and the side outer wall of the reinforcing support plate is connected to the side outer wall of the support frame.

[0012] Preferably, the reinforcing support plate is provided with a triangular plate structure, and the top outer wall of the support base and the auxiliary mounting plate are symmetrically provided with cylindrical grooves.

[0013] The beneficial effects of this utility model are:

[0014] 1. When using this cable laying tensioning device, the conductor tube is designed with elastic support through the mechanism components. When winding up a bent cable, the conductor tube can adapt to the bending force of the cable through its up and down displacement trajectory. At the same time, the conductor tube plays an auxiliary traction role. Before the cable enters, the conductor tube also plays an auxiliary role in cable management through its regularizing function. Therefore, after the cable bundle is pulled and regularized, there will be no tangling or knotting during winding. Furthermore, the movable design of the conductor tube can wind the cable to different height positions of the winding roller, thereby avoiding the phenomenon of stress concentration in the middle of the winding roller during cable winding, which can easily cause the cable to fall off after winding. The overall structure is ingeniously designed and has good practical effect.

[0015] 2. The tensioning device for cable laying uses a design where a larger diameter gear drives a smaller diameter gear to rotate, which in turn drives the winding roller to rotate. This design increases output stability and improves the winding speed of the cable. At the same time, the transmission control between the gears provides higher control precision, ensuring that the cable is wound evenly and tightly, avoiding cable damage caused by uneven winding force. The overall structure is ingeniously designed and has good practical effect. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a tensioning device for laying wires and cables, including a support frame 1, a take-up roller 2, and a conductor tube 3. The support frame 1 is configured with a "U" shape, and the take-up roller 2 is rotatably installed inside the support frame 1. The conductor tube 3 is located on the side of the take-up roller 2. An annular wire-locking groove is opened on the outer wall of the side of the take-up roller 2 at the middle position. The conductor tube 3 is configured as a horizontal funnel shape, and the smaller opening of the conductor tube 3 faces the take-up roller 2. A tensioning control mechanism 4 is provided above the support frame 1, an auxiliary traction mechanism 5 is provided on the outside of the conductor tube 3, and a positioning support mechanism 6 is provided on the side of the support frame 1. The annular wire-locking groove facilitates the initial part of the wire and cable winding to be wound to the outside of the take-up roller 2, achieving a better positioning effect. The horizontal funnel shape of the conductor tube 3 facilitates the guidance and winding of the wire and cable.

[0024] The tensioning control mechanism 4 includes a positioning support frame 401, a drive motor 402, a drive gear 403, a driven gear 404, and a transmission shaft 405. The positioning support frame 401 is fixedly installed on the top outer wall of the support frame 1. The positioning support frame 401 is configured in an "n" shape, and the drive motor 402 is fixedly installed on the top outer wall of the positioning support frame 401. The output end of the drive motor 402 is connected to the top outer wall of the drive gear 403. The driven gear 404 is meshed on the side of the drive gear 403. The transmission shaft 405 is fixedly installed on the bottom outer wall of the driven gear 404 located at the axis position. The bottom end of the transmission shaft 405 passes through... The top outer wall of the support frame 1 is rotatably mounted with the bottom inner wall of the support frame 1. The take-up roller 2 is fixedly mounted through the outside of the transmission shaft 405. The drive gear 403 and the driven gear 404 are both rotatably mounted with the top outer wall of the support frame 1. The diameter of the drive gear 403 is larger than the diameter of the driven gear 404. Here, the drive gear 403 and the driven gear 404 are set to different diameters so that the device can increase the output stability when the device is in transmission. At the same time, the design of the larger diameter drive gear 403 driving the smaller diameter driven gear 404 can increase the overall wire and cable tightening rate of the device.

[0025] The auxiliary traction mechanism 5 includes a positioning support bar 501, a limiting cylinder 502, a limiting piston rod 503, and a support spring 504. Positioning support bars 501 are symmetrically arranged on the top and bottom inner walls of the support frame 1. A limiting cylinder 502 is embedded inside the positioning support bar 501 located at the bottom. A limiting piston rod 503 is slidably installed inside the limiting cylinder 502. A support spring 504 connects the bottom outer wall of the limiting piston rod 503 and the bottom inner wall of the limiting cylinder 502. The spring 504 and the extended end of the limiting piston rod 503 are located above the limiting cylinder 502, and the extended end of the limiting piston rod 503 is connected to the bottom outer wall of the wire tube 3. The limiting cylinder 502 is filled with damping fluid. The outer wall of the top of the limiting piston rod 503 located at the piston plate position has a cylindrical hole 505 for the damping fluid to flow through. The design of filling the limiting cylinder 502 with damping fluid here has the effect of slowing down and protecting the movement of the limiting piston rod 503.

[0026] The positioning support mechanism 6 includes a support base 601, an auxiliary mounting plate 602, and a reinforcing support plate 603. The support base 601 is symmetrically arranged on both outer walls of the support frame 1 at the bottom position. The auxiliary mounting plate 602 is fixedly installed on the top outer wall of the support base 601. The reinforcing support plate 603 is symmetrically arranged on the top outer wall of the auxiliary mounting plate 602. The side outer wall of the reinforcing support plate 603 is connected to the side outer wall of the support frame 1. The reinforcing support plate 603 is provided with a triangular plate structure. The top outer walls of the support base 601 and the auxiliary mounting plate 602 are symmetrically provided with columnar grooves 604. The reinforcing support plate 603 is provided with a triangular plate structure to utilize the stability characteristics of the triangular support to achieve a more stable reinforcement support effect for the entire device. The columnar grooves 604 are provided to facilitate the use of external fasteners to position the entire device in a designated position.

[0027] Working principle: Refer to the instruction manual. Figure 5 First, external fasteners are needed to pass through the corresponding cylindrical grooves 604 to position the entire device in the designated location. Note that the side of the conduit 3 should face the wires and cables.

[0028] See the attached instruction manual. Figure 1 - Appendix Figure 2When it is necessary to tighten the wires and cables, the end of the wires and cables should first be passed through the conductor tube 3 and wound around to the outside of the annular wire clamping groove. Then, the drive motor 402 is turned on. When the drive motor 402 is turned on, its output end rotates and automatically drives the drive gear 403 to rotate. In turn, the drive gear 403 rotates and automatically drives the driven gear 404 to rotate, which in turn drives the transmission shaft 405 to rotate. Then, the transmission shaft 405 rotates and automatically drives the take-up roller 2 to rotate, which in turn drives the wires and cables to be wound up, thereby achieving the tightening effect. When the wires and cables are tightened to the appropriate length, the drive motor 402 can be turned off directly. It should be noted that the drive motor 402 has a self-locking function. After it is turned off, the take-up roller 2 can still maintain the same angle after rotation, thereby further achieving the effect of tightening the wires and cables.

[0029] See the attached instruction manual. Figure 3 - Appendix Figure 4 When the curved wire and cable are wound into the inside of the conductor tube 3, the wire and cable near the curled end will automatically slide inside the limiting cylinder 502 due to the pulling and resistance of the curved cable. At this time, the damping fluid inside the limiting cylinder 502 flows from one side of the piston plate inside the limiting piston rod 503 to the other side through the cylindrical hole 505. The incompressibility of the liquid reduces the movement speed of the limiting piston rod 503 and provides protection. At this time, the support spring 504 is in a contracted state due to the squeezing action of the limiting piston rod 503. When the wire and cable are in a smooth state, it can automatically resist the limiting piston rod 503 to reset, thereby driving the conductor tube 3 to reset. It should be noted that when one support spring 504 contracts, the support spring 504 in the corresponding direction will be stressed and stretched, thereby achieving the effect of force balance. At the same time, the movement of the conductor tube 3 can also wind the wire and cable to different sections of the take-up roller 2, thereby avoiding the phenomenon of the wire and cable being concentrated in the middle of the take-up roller 2.

[0030] It should be noted that the aforementioned drive motor 402 can be powered by existing operating techniques, whether by using a power supply device or by an external wire. These are all conventional operating techniques and will not be described in detail here.

[0031] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
