[0002] A wire tensioner, also known as a ratchet tensioner, is used in power construction to tighten power lines. Tightening power lines is a very important task that directly affects the use of the entire power line.

This mechanism allows the overhead line equipment to enter the support mechanism by opening it, and then secures the tensioning mechanism by extending a fixing mechanism, avoiding manual fixing. A second rotating mechanism is opened to rotate the tensioning mechanism, allowing selection of a tensioning mechanism matching the line specifications for power installation tensioning, thus improving the equipment's practicality. The mechanism includes a support mechanism, a fixing mechanism, a lifting mechanism, a first rotating mechanism, a second rotating mechanism, and a tensioning mechanism. The fixing mechanism is mounted on the support mechanism, the bottom of the lifting mechanism is mounted on the support mechanism, the first rotating mechanism is connected to the lifting mechanism, the second rotating mechanism is mounted on the first rotating mechanism, and the tensioning mechanism is mounted on the second rotating mechanism.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] Please refer to Figures 1-5. A power line tensioning mechanism includes a tensioning assembly for tensioning power lines. The tensioning assembly includes a base 1, a limiting frame 12, a limiting block 2, an extension rod 21, and an abutment wheel 31. The limiting frame 12 is symmetrically arranged on the base 1. The limiting block 2 is rotatably connected to the base 1. The extension rod 21 is symmetrically arranged on the limiting block 2, and the corresponding extension rod 21 is slidably connected to the limiting block 2. The corresponding abutment wheel 31 is elastically arranged with the extension rod 21, thus restricting the power line between the limiting frames 12. This allows the device to be placed directly on the power line without needing to install the device on a wire-laying device for tensioning, expanding the application range of the device.

[0029] The base 1 is symmetrically provided with first mounting brackets 11, each first mounting bracket 11 is fixedly connected to the base 1, and each limiting bracket 12 is fixedly connected to the corresponding first mounting bracket 11. Each limiting bracket 12 is slidably connected with a blocking block 13, and the end of the blocking block 13 is magnetically connected to the wall of the limiting bracket 12. The blocking block 13 on the corresponding limiting bracket 12 is slid open, and the power line is placed in the corresponding limiting bracket 12. The corresponding blocking block 13 is manually slid closed, and the blocking block 13 and the limiting bracket 12 are closed by the magnetic connection between the end of the blocking block 13 and the wall of the limiting bracket 12, thus restricting the power line between the limiting brackets 12. This allows the device to be placed directly on the power line without the need to install the device on the overhead line device and perform a tightening operation, thus expanding the application range of the device.

[0030] Each extension rod 21 is fixedly connected to a second mounting bracket 3. Each second mounting bracket 3 is symmetrically provided with a connecting block 33, and each connecting block 33 is fixedly connected to the corresponding second mounting bracket 3. Each connecting block 33 is movably connected to a side wheel 32, and an abutment wheel 31 is elastically connected between the side wheels 32. Each side wheel 32 has an arc-shaped chamfer at its end. Each abutment wheel 31 has a cavity, and a connecting rod 34 is slidably connected to each cavity. The connecting rod 34 is fixedly connected to the side wheel 32, and a spring 35 is provided between the cavity and the connecting rod 34. The end of each spring 35 is fixedly connected to the corresponding cavity and the connecting rod 34. A drive motor 14 is provided between the base 1 and the limiting block 2, and the drive motor 14 is fixedly connected to the base 1. Block 2 is fixedly connected to the output end of the drive motor 14. After the power line is restricted by the limit frame 12, the power line passes between the corresponding second mounting frame 3. The wall of the power line is in close contact with the abutment wheel 31. When power lines of different sizes come into contact with the abutment wheel 31, the edge of the power line is in close contact with the side wheel 32. The power line pushes the side wheel 32. The side wheel 32 stretches the spring 35 through the connecting rod 34. The spring 35 deforms and applies the deformation force to the connecting rod 34. The spring 35 pulls the connecting rod 34 and drives the side wheel 32 to move toward the power line. This adapts to different power lines. The output end of the drive motor 14 drives the limit block 2 to rotate. The limit block 2 drives the corresponding abutment wheel 31 to move in a circle. During the movement, the power line is tensioned.

[0031] The drive motor 14 is electrically connected to a power supply and a controller, and both the power supply and the controller are fixedly connected to the base 1. The power supply and the controller control the start and stop of the drive motor 14. The controller of the drive motor 14 is a mature existing technology, so it is not described in detail in this article.

[0032] Each extension rod 21 is fixedly connected to a rack 25, and a gear 24 meshes between the racks 25. A transmission sleeve 23 is fixedly connected to the gear 24, and each transmission sleeve 23 is rotatably connected to a limiting block 2. A connecting hole 26 is circumferentially opened on the limiting block 2. A magnetic suction rod is symmetrically arranged at the end of the knob 22. The magnetic suction rod is magnetically connected to the corresponding connecting hole 26. When the knob 22 is lifted and rotated manually, the knob 22 drives the transmission sleeve 23, which drives the gear 24. The gear 24 meshes with the rack 25, and the rack 25 is driven to push and pull the extension rod 21 back and forth. The extension rod 21 drives the second mounting bracket 3 to move. During the movement of the second mounting bracket 3, the extension rod 21 is extended and contracted to different degrees under different tensions of the power line. After the extension rod 21 is adjusted, the knob 22 is pressed down and connected to the corresponding connecting hole 26 through the magnetic suction rod to limit the rotation of the gear 24.

[0033] Working principle: The blocking block 13 on the corresponding limiting frame 12 is slid open, and the power line is placed in the corresponding limiting frame 12. The blocking block 13 is then manually slid closed. The magnetic connection between the end of the blocking block 13 and the wall of the limiting frame 12 closes the connection, confining the power line within the limiting frames 12. This allows the device to be placed directly on the power line, eliminating the need for tensioning after installation on a wiring device, thus expanding its application range. After the power line is confined by the limiting frame 12, it passes between the corresponding second mounting brackets 3. The wall of the power line is in close contact with the abutment wheel 31. When power lines of different sizes contact the abutment wheel 31, the edge of the power line is in close contact with the side wheel 32. The power line pushes the side wheel 32, which stretches the spring 35 through the connecting rod 34. The spring 35 deforms and applies the deformation force. On the connecting rod 34, the spring 35 pulls the connecting rod 34 and drives the side wheel 32 to move toward the power line to adapt to different power lines. The output end of the drive motor 14 drives the limit block 2 to rotate. The limit block 2 drives the corresponding abutment wheel 31 to move in a circle. During the movement, the power line is tensioned. The knob 22 is lifted up manually and rotated manually. The knob 22 drives the transmission sleeve 23 during rotation. The transmission sleeve 23 drives the gear 24. The gear 24 meshes with the rack 25. The rack 25 is meshed and drives the extension rod 21 to push and pull back and forth. The extension rod 21 drives the second mounting bracket 3 to move. During the movement of the second mounting bracket 3, the extension rod 21 is extended and contracted to different degrees under different tensions of the power line. After the extension rod 21 is adjusted, the knob 22 is pressed down and connected to the corresponding connecting hole 26 through the magnetic rod to limit the rotation of the gear 24.
