Description

Technical Field

[0001] The present invention relates to the technical field of tension machines, in particular to a towed electric tension machine and a method for tensioning transmission lines. Background Art

[0002] For example, the patent number CN107394679A is a split tensioner for tensioning transmission lines. The tensioner includes: a support device, a tension wheel assembly, a tensioning mechanism, and a power mechanism. The tension wheel assembly is rotatably connected to the support device for winding the conductor. The tensioning mechanism is connected to the support device and rotatably connected to the tension wheel assembly, so that the conductor remains in a tensioned state under the action of external traction. The power mechanism is detachably connected to the tensioning mechanism, so that the tensioning mechanism generates tension. In the present invention, the power mechanism and the tensioning mechanism are detachably connected, so that the power mechanism and the tensioning mechanism can be split structures. When the tensioner is placed on a tension locomotive, the power mechanism and the tensioning mechanism can be placed separately, which greatly saves space and allows the position of the tensioner on the tension locomotive to be lowered as needed. In particular, when winding carbon fiber conductors, the transportation height of the tension locomotive can be effectively reduced. In addition, the overall weight of the tensioner is also reduced.

[0003] During the above-mentioned cable traction process, there are problems such as large friction resistance, uneven tension distribution, and easy slipping or kinking of wires. These problems are particularly prominent in complex terrain or long-distance laying operations, which seriously affect construction efficiency and cable laying quality. The above-mentioned traction equipment has deficiencies in tension control accuracy, dynamic response capability, and adaptability to cables of different specifications, and it is difficult to meet the increasingly complex needs of transmission line construction. Therefore, the present application provides a towed electric tension machine and method for transmission line tensioning to meet the needs. Summary of the Invention

[0007] Wherein, a support ring for limiting the sliding position of the top sheet is provided on one side of the outer surface of the support rod, and a plurality of arc grooves distributed at equal intervals are opened on the outer surface of the top sheet.

[0008] The tapered roller assembly includes two ring frames, both of which are fixedly mounted on the outer surface of the support rod, and the wire wheel is rotatably mounted between the two ring frames, and a damping plate is provided on one side of the wire wheel.

[0009] The inclined roller assembly includes a load-bearing frame, which is fixedly mounted on the middle of the upper end of the support frame. Two support plates are symmetrically arranged on the upper end of the load-bearing frame, and limiting rods are arranged on the opposite surfaces of the two support plates.

[0010] Among them, the vibration assembly includes an elliptical shell and two connecting plates, both of which are slidably installed on the outer surface of the limit rod, and a telescopic rod is provided at the bottom of the two connecting plates, and the telescopic rod is fixedly installed on the upper end of the load-bearing frame.

[0011] Among them, two inclined arc rollers are symmetrically arranged between the two connecting plates, and the two inclined arc rollers are combined to form an "eight" shape.

[0012] Wherein, a support rod is provided between the two connecting plates, and a vibration machine is fixedly installed on the upper end of the support rod.

[0013] Among them, two connecting plates are symmetrically arranged between the two connecting plates, and spring columns are provided at the upper and lower ends of the two connecting plates. The spring columns are fixedly installed on the inner wall of the elliptical shell, and the contact end of the vibration machine contacts the inner wall of the elliptical shell. Several mounting grooves are opened on the upper part of the outer surface of the elliptical shell, and round rollers are rotatably installed inside the mounting grooves.

[0014] The present application provides a method for using a towed electric tensioner for tensioning a transmission line. The method uses a towed electric tensioner for tensioning a transmission line. The specific method of use is as follows: Step 1: When in use, the wire is wound around the surface of the traction wheel, the inclined roller assembly, the vibration assembly and the tension adjustment assembly. During the winding and traction process of the wire, the vibration assembly cooperates with the inclined roller assembly to change the overall flexibility of the cable to prevent the cable from being kinked or entangled later. The tension adjustment assembly is provided to adjust the tension of the wire according to the traction of the wire; Step 2: When the cable is sleeved on the surface of the conical roller assembly through the traction wheel, the inclined roller assembly and the vibration assembly, the conical roller assembly can cooperate with the inclined roller assembly and the vibration assembly to improve the wire guiding and evenly distribute the tension, and can cooperate with the inclined roller assembly and the vibration assembly to adjust the surface tension of the wire.

[0015] In summary, the technical effects and advantages of the present invention are as follows: 1. During the wire pulling process, the vibrator transmits vibrations to the wire surface through the elliptical shell and circular rollers, causing it to slightly displace, thereby effectively reducing the friction between the wire and the contact surface. This structure significantly reduces the static friction coefficient between the wire and supporting structures such as the ground and guide wheels, reducing the "sticking effect" and allowing the wire to slide more smoothly, avoiding increased pulling resistance or wire damage caused by excessive friction. The vibration effect also breaks the local stress balance in the wire's movement, helping it to more easily escape obstacles or bends. 2. In the present invention, the surface of the inclined arc roller is provided with an arc-shaped contact surface, so that the wire fits closely with it, increasing the effective contact area between the wire and the roller surface, improving the friction, avoiding slipping, and ensuring that the wire can drive the arc roller to roll synchronously during the traction process; at the same time, the inclined arc roller adopts the oblique contact structure of the figure, which applies a reverse torque to the wire during the rolling process, effectively offsetting the torsional tendency of the wire during traction, and preventing it from spiral deformation, kinking or entanglement.

[0016] 3. In the present invention, during the traction process, the electric wire is wound around the surface of the pulley and drives it to rotate. By setting a damping plate, rotational resistance is applied to the pulley, which effectively increases the friction between the pulley and the electric wire, and forms a controllable reverse resistance during the traction process, thereby realizing dynamic tension adjustment. This structure can adjust the damping size according to actual traction requirements to avoid problems such as slipping and breakage caused by excessive traction or uneven tension. The presence of the damping plate increases the friction coefficient between the pulley and the electric wire, prevents the electric wire from slipping during operation, significantly reduces the tension fluctuation caused by slipping, and ensures the stability of the traction process. The wire wheel adopts a conical structure design, which allows the wire to automatically adjust its contact position along the conical surface during the winding process, improving the stability of the running path and enhancing the guiding performance. This design has good adaptability and can adapt to wires of different diameters, enhancing the versatility of the equipment, while achieving uniform distribution of traction tension and reducing the risk of local stress concentration. In addition, a convex ring is provided on the wire wheel to act as a physical isolation, limiting the axial deviation of the wire. This structure can effectively prevent the wire from overlapping or jumping during the traction process, improve the neatness of the wiring, and avoid increased traction resistance caused by winding.

[0017] 4. In the present invention, dynamic adjustment of tension is achieved by setting a top plate inside the arc groove. When the wire is wound in the arc groove and tensioned, the top plate is pushed to produce displacement, thereby compressing the buffer device composed of a spring and a damping rod. The buffer system can automatically adjust the output resistance according to the tension size to achieve dynamic adjustment of the traction tension, effectively avoiding operational abnormalities caused by overload or tension relaxation. An extrusion pad is provided between two adjacent top plates, which plays a connecting and buffering role during the rotation process. This design can effectively avoid gaps or jumps between the top plates, maintain the continuity of operation, reduce friction and vibration, and prevent local tension imbalance caused by top plate misalignment.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Implementation 1. Reference Figures 1 to 16The illustrated towable electric tension machine for tensioning transmission lines comprises a support frame 1, a traction wheel 6 being provided on one side of the interior of the support frame 1, a driving tooth 8 being provided in the middle of the support frame 1, a tension adjustment assembly 4 for adjusting the tension of the wire being provided on the other side of the interior of the support frame 1, and a tapered roller assembly 5 for improving the guiding of the wire and evenly distributing the tension, an inclined roller assembly 2 being provided in the middle of the support frame 1, and a vibration assembly 3 being provided inside the inclined roller assembly 2 for improving the overall flexibility of the cable by vibration; It is worth noting that when in use, the electric wire is wound around the surfaces of the traction wheel 6, the inclined roller assembly 2, the vibration assembly 3 and the tension adjustment assembly 4. During the winding and traction process of the electric wire, the vibration assembly 3 cooperates with the inclined roller assembly 2 to change the overall flexibility of the cable to prevent the cable from being kinked or entangled later. In addition, the tension adjustment assembly 4 is provided to adjust the tension of the electric wire according to the traction of the electric wire. Among them, during the traction process, the vibration component 3 and the inclined roller component 2 work together to change the overall flexibility of the cable through vibration and oblique contact, effectively preventing the cable from being kinked or entangled during the laying process. At the same time, the tension adjustment component 4 can adjust its tension in real time according to the traction state of the wire to ensure that the cable is evenly stressed and operates stably. This structural design not only improves the controllability and safety of the cable laying process, but also significantly improves the laying quality and construction efficiency of the cable.

[0023] When the cable passes through the traction wheel 6, the inclined roller assembly 2 and the vibration assembly 3 and is sleeved on the surface of the conical roller assembly 5, the conical roller assembly 5 can cooperate with the inclined roller assembly 2 and the vibration assembly 3 to improve the wire guiding and evenly distribute the tension, and can cooperate with the inclined roller assembly 2 and the vibration assembly 3 to adjust the surface tension of the wire.

[0024] The tapered roller assembly 5 adopts a tapered structure design, which can automatically adjust the contact angle according to the cable diameter, effectively improving the stability of the cable running path, reducing deviation and jump, and ensuring straightness and smoothness during the laying process. This structure makes the cable more evenly stressed during the pulling process, avoiding local stress concentration and reducing the risk of deformation or breakage due to uneven tension. At the same time, the vibration component 3 can enhance the flexibility of the cable, and the inclined roller component 2 changes the movement direction of the cable through the inclined guiding effect. The two work together with the tapered roller component 5 to achieve dynamic adjustment of the cable surface tension, significantly improving the equipment's adaptability to cables of different specifications and materials. In addition, the inclined roller assembly 2 and the vibration assembly 3 work together to optimize the cable posture control, and cooperate with the guiding function of the tapered roller assembly 5 to effectively prevent the cable from kinking, looping or winding during the laying process.

[0025] Embodiment 2: This embodiment provides a further technical solution for the inclined roller assembly 2 and the vibration assembly 3.

[0026] The inclined roller assembly 2 includes a load-bearing frame 21, which is fixedly mounted on the middle of the upper end of the support frame 1. Two support plates 22 are symmetrically provided on the upper end of the load-bearing frame 21, and limit rods 23 are provided on the opposite surfaces of the two support plates 22.

[0027] The vibration assembly 3 includes an elliptical shell 32 and two connecting plates 31. The two connecting plates 31 are slidably mounted on the outer surface of the limiting rod 23. The bottom of the two connecting plates 31 is provided with a telescopic rod 25, and the telescopic rod 25 is fixedly mounted on the upper end of the load-bearing frame 21.

[0028] Two inclined arc rollers 24 are symmetrically arranged between the two connecting plates 31. The two inclined arc rollers 24 are combined into an "eight" shape. A support rod 37 is provided between the two connecting plates 31. A vibrator 36 is fixedly installed on the upper end of the support rod 37.

[0029] Two connecting plates 35 are symmetrically arranged between the two connecting plates 31. Spring columns 34 are provided at the upper and lower ends of the two connecting plates 35. The spring columns 34 are fixedly mounted on the inner wall of the elliptical shell 32. The contact end of the vibrator 36 contacts the inner wall of the elliptical shell 32. A plurality of mounting grooves 33 are opened on the upper outer surface of the elliptical shell 32, and a round roller 38 is rotatably mounted inside the mounting groove 33.

[0030] It is worth noting that after the wire is wound on the surface of the traction wheel 6, the wire will be wound from the surface of the inclined arc roller 24 and the round roller 38, and finally the wire will be wound on the surface of the tension adjustment component 4 or the tapered roller component 5. During the process of wire traction, the tension generated by the wire traction makes the wire close to the surface of the round roller 38 and the inclined arc roller 24. Since the two inclined arc rollers 24 arranged in an "eight" shape have an arc-shaped contact surface, the wire is closely attached to them during the traction process and drives them to roll. The inclined arc roller 24 adopts Figure 8 The structural design shown effectively adjusts the torsional force on the wire by rolling and making oblique contact with the surface of the wire.

[0031] During the traction process, the wire is sequentially wound around the traction wheel 6, the inclined arc roller 24 and the round roller 38, and finally enters the tension adjustment assembly 4 or the tapered roller assembly 5. This multi-stage guiding structure effectively ensures the stability of the wire running track and reduces the jumping, slipping or dislocation caused by path deviation. The two inclined arc rollers 24 are arranged in an "eight" shape, forming an asymmetric but complementary contact surface, so that the wire is guided in both directions during the traction process. This design can automatically adapt to the tensile changes of the wire in different directions, balance the lateral stress during the traction process, prevent local excessive force, and improve the dynamic tension balance capability. The surface of the inclined arc roller 24 is provided with an arc-shaped contact surface, which makes the wire fit closely with it, increases the effective contact area between the wire and the roller surface, improves the friction, avoids slipping, and ensures that the wire can drive the arc roller to roll synchronously during the traction process; At the same time, the inclined arc roller 24 adopts Figure 8 The oblique contact structure applies reverse torque to the wire during rolling, effectively offsetting the twisting tendency of the wire during traction and preventing it from spiral deformation, kinking or entanglement. The round roller 38 serves as an auxiliary supporting component and together with the inclined arc roller 24 constitutes a composite supporting structure, further enhancing the smoothness and guiding accuracy of the wire operation. After pre-processing by the inclined arc roller 24 and the round roller 38, the wire is in a good tension state and a smooth running path, providing a good foundation for the subsequent work of the tension adjustment component 4 or the conical roller component 5.

[0032] When the surface tension of the wire needs to be adjusted, the telescopic rod 25 drives the connecting plate 31 to slide on the surface of the limiting rod 23, and the connecting plate 31 drives the inclined arc roller 24 to move. The tension of the wire stretched between the tension adjustment assembly 4 and the traction wheel 6 or the tapered roller assembly 5 and the traction wheel 6 is adjusted by adjusting the height of the inclined arc roller 24; By controlling the extension and retraction of the telescopic rod 25, the connecting plate 31 is driven to slide along the limiting rod 23, thereby driving the inclined arc roller 24 to move up and down. The change in the position of the inclined arc roller 24 directly affects the stress state of the wire in the traction path, achieving precise adjustment of the wire tension to meet the tension control requirements under different working conditions. By adjusting the height of the inclined arc roller 24, the contact angle and pressure between it and the wire can be changed, adapting to cables of various specifications and materials. It has good self-adaptation and can dynamically match the tension according to the characteristics of different cables, effectively avoiding the problem of excessive or insufficient tension caused by differences in wire diameters. The height change of the inclined arc roller 24 will also affect the path length and tensioning state of the wire between the tension adjustment component 4 or the tapered roller component 5 and the traction wheel 6, thereby optimizing the force distribution of the wire between key components, reducing local stretching or relaxation, and reducing the risk of stress concentration.

[0033] When the wire contacts the surface of the round roller 38, the round roller 38 will be driven to rotate as the wire is pulled. The vibrator 36 is a prior art. The vibrating end of the vibrator 36 drives the elliptical shell 32 to rotate, and the elliptical shell 32 transmits the vibration to the wire through the round roller 38. When the wire is vibrated during the pulling process, this vibration can reduce the static friction coefficient between the wire and the contact surface. By causing a slight displacement on the surface of the wire, it reduces the "adhesion" effect between the wire and the ground or other supporting structures, allowing the wire to slide more smoothly and reducing the torsion tendency caused by friction resistance. The spring column 34 can assist in supporting the elliptical shell 32.

[0034] Among them, during the wire traction process, the vibrator 36 transmits the vibration effect to the surface of the wire through the elliptical shell 32 and the round roller 38, causing it to produce a small displacement, thereby effectively reducing the friction between the wire and the contact surface. This structure significantly reduces the static friction coefficient between the wire and supporting structures such as the ground, guide wheels, etc., reduces the "adhesion effect", and allows the wire to slide more smoothly, avoiding increased traction resistance or wire damage due to excessive friction. The effect of vibration helps to break the local stress balance formed by the wire during movement, making it easier to break away from obstacles or bending points.

[0035] In addition, this structure can effectively prevent the wires from getting tangled, looped or entangled during the traction process. Since the vibration reduces the friction resistance and releases some of the stress accumulated inside the wires, the torsional tendency is significantly reduced. It is particularly suitable for cable laying operations over long distances and in complex terrain.

[0036] The vibration machine 36, as an existing mature device, drives the elliptical shell 32 to rotate, and then the elliptical shell 32 transmits the vibration to the wire through the round roller 38, forming an efficient vibration transmission chain to ensure stable output of vibration energy. The spring column 34 provides elastic support for the elliptical shell 32, playing a buffering and stabilizing role. On the one hand, it absorbs part of the vibration impact to prevent structural resonance or damage. On the other hand, it maintains a good contact state between the elliptical shell 32 and the round roller 38 to ensure the continuity and stability of vibration transmission. At the same time, the vibration frequency and amplitude can be adjusted according to wires of different wire diameters and materials.

[0037] Embodiment 3: This example provides a further technical solution for the tapered roller assembly 5 .

[0038] The tapered roller assembly 5 includes a plurality of wire wheels 52 distributed in a ring array. The wire wheels 52 are conical in shape and are placed at an inclined angle. The outer surface of the wire wheel 52 is provided with a plurality of convex rings 54 distributed at equal intervals.

[0039] The tapered roller assembly 5 includes two ring frames 51 , both of which are fixedly mounted on the outer surface of the support rod 41 , and a wire wheel 52 is rotatably mounted between the two ring frames 51 , with a damping plate 53 provided on one side of the wire wheel 52 .

[0040] It is worth noting that the wire is wound around the surface of the pulley 52, and the pulley 52 will rotate as the wire is pulled, and the design of the damping plate 53 is to hinder the rotation of the pulley 52, so that the friction coefficient between the pulley 52 and the wire increases, and the ring frame 51 rotates with the rotation of the tension adjustment component 4, and the wire is pulled by the rotation of the ring frame 51 in conjunction with the traction wheel 6. Because the designed pulley 52 is conical in shape and the convex ring 54 is provided, it is used to prevent the winding of the wire, so that the wire can be guided and the tension is evenly distributed during the traction process.

[0041] Among them, during the traction process, the electric wire is wound around the surface of the pulley 52 and drives it to rotate. By setting the damping plate 53, rotational resistance is applied to the pulley 52, which effectively increases the friction between the pulley and the electric wire, and forms a controllable reverse resistance during the traction process, thereby realizing dynamic tension adjustment. This structure can adjust the damping size according to actual traction needs to avoid problems such as slipping and breakage caused by excessive traction or uneven tension. The presence of the damping plate 53 increases the friction coefficient between the pulley and the electric wire, prevents the electric wire from slipping during operation, significantly reduces the tension fluctuation caused by slipping, and ensures the stability of the traction process.

[0042] The conical structure of the wire reel 52 allows the wire to automatically adjust its contact position along the conical surface during winding, improving the stability of the running path and enhancing the guiding performance. This design has good adaptability and can adapt to wires of different diameters, enhancing the versatility of the equipment. At the same time, it achieves uniform distribution of traction tension and reduces the risk of local stress concentration. In addition, a convex ring 54 is provided on the wire wheel 52, which plays a physical isolation role and limits the deviation of the wire in the axial direction. This structure can effectively prevent the wire from overlapping or jumping during the traction process, improve the neatness of the wire arrangement, and avoid the increase of traction resistance caused by winding.

[0043] Embodiment 4: This embodiment provides a further technical solution for the tension adjustment component 4.

[0044] The tension adjustment assembly 4 includes a support rod 41 and a support ring 45. The outer surfaces of the support rod 41 and the traction wheel 6 are both provided with gears 7, which are engaged with the driving teeth 8. The outer surface of the support rod 41 is provided with a plurality of damping rods 47 distributed in a ring array, and the outer surface of the damping rod 47 is provided with a spring 46. One end of the damping rod 47 is connected to the top plate 44, and one end of the top plate 44 is connected to the extrusion pad 43.

[0045] A support ring 45 for limiting the sliding position of the top sheet 44 is provided on one side of the outer surface of the support rod 41 . The outer surface of the top sheet 44 is provided with a plurality of arc grooves 42 distributed at equal intervals.

[0046] It's worth noting that when the wires are wound within the arc grooves 42, the tension on the wires causes the top sheet 44 to move, which in turn compresses the buffer mechanism comprised of a spring 46 and a damping rod 47. The arc grooves 42 are arranged in an annular pattern, forming a complete ring structure. Each time the top sheet 44 rotates a full circle and contacts the wires again, the damping force provided by the damping rod 47 and spring 46 is automatically adjusted based on the wire tension. Furthermore, a compression pad 43 is provided to connect two adjacent top sheets 44, ensuring a smooth transition between them.

[0047] Among them, dynamic adjustment of the tension is achieved by setting a top plate 44 inside the arc groove 42. When the wire is wound in the arc groove 42 and is tensioned, the top plate 44 is pushed to produce displacement, thereby compressing the buffer device composed of a spring 46 and a damping rod 47. The buffer system can automatically adjust the output resistance according to the tension size, thereby achieving dynamic adjustment of the traction tension and effectively avoiding abnormal operation caused by overload or tension relaxation. An extrusion pad 43 is provided between two adjacent top plates 44, which plays a connecting and buffering role during the rotation process. This design can effectively avoid gaps or jumps between the top plates, maintain the continuity of operation, reduce friction and vibration, and prevent local tension imbalance caused by top plate misalignment.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
