[0002] A tension machine is a tension wheel used in tension stringing of power transmission lines and high-altitude cableway erection operations. As the main equipment for tension stringing in line construction, existing tension machines generally use hydraulic braking to generate tension, and the tension can be adjusted by the outlet pressure of the tension machine's motor.

[0003] The patent publication number "CN221796580U" discloses an adjustable tension power line tensioning machine, which includes a mounting plate. A fixing plate is fixedly connected to the upper surface of the mounting plate, and a rotating motor is fixedly connected to the back of the fixing plate. A winding wheel is fixedly connected to the output end of the rotating motor. Two upright plates are fixedly connected to the upper surface of the mounting plate.

Two electric hydraulic rods are fixedly embedded inside the swing rod.

[0004] As shown in the above technology, existing mechanical tensioners adjust the tension using a hydraulic structure. During long-term operation, the equipment is prone to tension fluctuations that can cause the conductor to become too loose or too tight. Moreover, the accuracy of tension adjustment cannot be guaranteed, which affects construction efficiency and the service life of the conductor. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable tension electric tension machine for power line wiring, which solves the problem of weak dynamic tension adjustment capability of existing adjustable tension electric tension machines for power line wiring.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A tension-adjustable electric tension machine for power lines includes a mobile trolley, the top of which is equipped with a winding assembly and guide wheels. A tension adjustment mechanism for dynamically adjusting the tension of the wire and preventing it from slipping is provided between the winding assembly and the guide wheels. The tension adjustment mechanism includes a dynamic tension adjustment assembly and an anti-slip assembly.

[0007] Preferably, a rotating rod is rotatably connected between the two opposite sides of the front and rear bearing seats, and a guide wheel is fixedly connected to the surface of the rotating rod. The pressure sensor is used to detect the pressure above the guide wheel.

[0008] Preferably, a controller is mounted on the front side of the winding assembly, the pressure sensor is electrically connected to the controller, and the electric push rod is also electrically connected to the controller.

[0009] Preferably, the anti-detachment component includes a bidirectional threaded rod, which is rotatably connected to the front and back of the U-shaped plate. The surface of the movable plate is threaded with two movable plates, one in front and one in back, and the top of each movable plate is fixedly connected with a support component.

[0010] Preferably, the two support components are arranged symmetrically and alternately. Each support component includes a sliding sleeve, which is fixedly connected to the top of the movable plate and movably mounted outside the rotating rod.

[0012] This invention provides an electric tensioner for power line overhead lines with adjustable tension. Compared with the prior art, it has the following advantages: 1. This adjustable tension electric tensioner for power lines includes a dynamic tension adjustment component comprising a support rod. The support rod is fixedly connected to a U-shaped plate at its top. The U-shaped plate has grooves on both its front and back sides, and bearing seats are slidably connected to the inner surfaces of both grooves. During the movement of the power line, a pressure sensor monitors the pressure of the power line on the guide wheel in real time. If the tension is too high or too low, the height of the guide wheel is adjusted to avoid the influence of tension fluctuations, which is conducive to the stable transmission of the power line and improves the practicality of the device.

[0013] 2. This adjustable tension electric tensioner for power lines uses an anti-detachment component, including a bidirectional threaded rod, which is rotatably connected to the front and back of a U-shaped plate. The surface of the moving plate is threaded with two moving plates, and the top of each moving plate is fixedly connected with a support component. Anti-detachment components are set on both sides of the wire, clamping the wire to both sides, thereby effectively preventing the wire from shifting and detaching from the wire wheel during movement, further ensuring the stability of the wire during movement.

[0016] 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.

[0017] Please see Figures 1-4 This adjustable tension electric tensioner for power lines offers two technical solutions: The first embodiment includes a mobile trolley 1, with a winding assembly 2 and a guide wheel 3 installed on the top of the mobile trolley 1. A tension adjustment mechanism for dynamically adjusting the tension of the wire and preventing it from slipping is provided between the winding assembly 2 and the guide wheel 3. The tension adjustment mechanism includes a dynamic tension adjustment assembly 4 and an anti-slip assembly 5. The dynamic tension adjustment assembly 4 includes a support rod 41, with a U-shaped plate 42 fixedly connected to the top of the support rod 41. The U-shaped plate 42 has grooves 43 on both its front and back sides, and bearing seats 44 are slidably connected to the inner surfaces of both grooves 43. Connecting rods 45 are fixedly connected to the bottom of both grooves 43. An electric push rod 46 is fixedly connected to the bottom of the inner wall of the support rod 41. The telescopic end of the electric push rod 46 is fixedly connected to the connecting rod 45. A pressure sensor 49 is embedded in the bottom of the bearing seat 44. A rotating rod 47 is rotatably connected between opposite sides of the two bearing seats 44. A guide wheel 48 is fixedly connected to the surface of the rotating rod 47. The pressure sensor 49 is used to detect the pressure above the guide wheel 48. A controller 6 is installed on the front of the winding assembly 2. The pressure sensor 49 is electrically connected to the controller 6, and the electric push rod 46 is also electrically connected to the controller 6.

[0018] During the movement of the wire, the pressure sensor 49 monitors the pressure of the wire on the guide wheel 48 in real time. When the tension is too high or too low, the height of the guide wheel 48 is adjusted to avoid the influence of tension fluctuations, which is conducive to the stable transmission of the wire and improves the practicality of the device.

[0019] The second embodiment differs from the first embodiment in that: the anti-detachment component 5 includes a bidirectional threaded rod 51, which is rotatably connected to the front and back of the U-shaped plate 42. The surface of the movable plate 52 is threaded with two movable plates 52, and the top of each of the two movable plates 52 is fixedly connected with a support component 53. The two support components 53 are symmetrically staggered. The support component 53 includes a sliding sleeve 531, which is fixedly connected to the top of the movable plate 52 and movably installed outside the rotating rod 47. A rotating ring 532 is rotatably connected to one side of the sliding sleeve 531. An extension rod 533 is fixedly connected to the surface of the rotating ring 532. An arc-shaped plate 534 is rotatably connected to one side of the extension rod 533.

[0020] Anti-detachment components 5 are installed on both sides of the wire. The anti-detachment components 5 are clamped to both sides of the wire, thereby effectively preventing the wire from deviating and detaching from the wire wheel during the movement, and further ensuring the stability of the wire when it moves.

[0021] In use, the wire in the winding assembly 2 is passed over the top of the guide wheel 48 and under the guide wheel in the guide wheel assembly 3. Then, the bidirectional threaded rod 51 is rotated to bring the two support assemblies 53 closer together, and the position and angle of the arc plate 534 are adjusted to match the position and angle of the wire. The bidirectional threaded rod 51 is rotated again to make the arc plate 534 fit onto one side of the wire. When the wire moves, the guide wheel 48 is subjected to the pressure of the wire. The pressure sensor 49 detects the pressure. If the pressure is too high, it indicates that the tension is too high. At this time, the controller 6 controls the electric push rod 46 to work. The electric push rod 46 moves the guide wheel 48 downward, and vice versa.
