Description

Technical Field

[0001] The utility model relates to the technical field of power line installation, and particularly relates to a wire tightener for power line installation. Background Technique

[0002] Power lines are the main components of the power grid and are used to transmit electric energy from power plants to power load centers and for the interconnection between load centers. A wire tightener, also known as a ratchet tightening device, is a tool used to tighten conductors during the construction of overhead line laying. It mainly consists of components such as a steel wire rope or galvanized iron wire, a wire clamping pliers, a special wrench, and a ratchet drum. When in use, first loosen the steel wire rope or galvanized iron wire and fix it on the cross arm, clamp the conductor with the wire clamping pliers, and then by turning the special wrench, using the anti-reverse function of the pawl, gradually wind the steel wire rope or galvanized iron wire around the ratchet drum to achieve the tightening of the conductor. The wire tightener is widely used in multiple industries such as construction, highways, bridges, and power. Its design aims to improve construction efficiency, reduce the manual labor burden, and ensure the accuracy and safety of conductor tightening. When installing power lines, in order to tighten the conductors or cables in the overhead lines to the specified sag and tension, a wire tightener is usually used. By using the wire tightener, it is possible to prevent the conductors from swinging too much due to factors such as wind and gravity, thereby reducing the risk of the conductors coming into contact with other objects, improving the safety of the line, and at the same time helping to maintain the stable state of the conductors, being able to avoid vibration and swinging caused by external factors, and being beneficial to extending the service life of the line.

[0003] In the prior art, when using a wire tightener to tighten a cable, usually by manually turning the wrench on the wire tightener, using the anti-reverse function of the pawl to wind the steel wire rope or galvanized iron wire around the ratchet drum to achieve tightening. Since the manual turning method requires repeated operations during the tightening process, it will consume a relatively large amount of manpower, making the operation relatively inconvenient. At the same time, it cannot well improve the tightening speed and the overall efficiency of power line installation. Therefore, in order to solve the above problems, a wire tightener for power line installation is proposed. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0023] A wire tightener for electric power line installation includes a body. The body includes a hook seat 1, and a hook 11 is movably connected inside the hook seat 1. Through the arrangement of the hook seat 1, the hook 11 can move. By hanging the hook 11 on the angle steel of the cross arm or other fixed points, it can ensure that the wire tightener can maintain stability during use and is not easy to fall off or move;

[0024] A tightening mechanism is provided on the surface of the hook seat 1. The tightening mechanism includes a first connecting plate 2 which is arranged on the surface of the hook seat 1. An activity groove 21 is opened inside the first connecting plate 2. A positive and negative screw rod 22 is movably connected inside the activity groove 21. The positive and negative screw rod 22 is movably connected with the first connecting plate 2. A motor 23 is fixedly installed on the surface of the first connecting plate 2. The positive and negative screw rod 22 is fixedly connected with the output end of the motor 23. A moving block 24 is threadedly connected to the surface of the positive and negative screw rod 22. An activity rod 25 is movably connected to the surface of the moving block 24. The activity rod 25 is movably connected to the surface of a second connecting plate 26. By rotating the positive and negative screw rod 22, the moving block 24 can be driven to move. Furthermore, the movement of the moving block 24 can make the activity rod 25 move and drive the second connecting plate 26 to move, so as to control the distance between the two hooks 11, making it more convenient to tighten the cable without manual operation.

[0025] Furthermore, the tightening mechanism further includes a limiting block 27 which is fixedly connected to the surface of the moving block 24. A limiting groove 28 is opened on the inner wall of the activity groove 21. One end of the limiting block 27 is fixedly connected with the moving block 24, and the other end of the limiting block 27 is movably connected with the limiting groove 28. Through the cooperation of the limiting block 27 and the limiting groove 28, the moving block 24 can be limited, avoiding the deviation of the moving block 24 under the action of the positive and negative screw rod 22 and facilitating the stable movement of the moving block 24.

[0026] Furthermore, two groups of moving blocks 24 are movably connected to the surface of the positive and negative screw rod 22, and the moving blocks 24 move inside the activity groove 21. Through the arrangement of the moving blocks 24, the activity rod 25 can move through a rotating shaft under the action of the moving blocks 24, enabling the second connecting plate 26 to perform vertical movement, thus facilitating the adjustment of the distance between the two groups of hooks 11.

[0027] Furthermore, one end of the activity rod 25 is movably connected with the moving block 24 through a rotating shaft, and the other end of the activity rod 25 is movably connected with the second connecting plate 26 through a rotating shaft. By connecting the moving block 24 and the second connecting plate 26 through the activity rod 25, when the moving block 24 moves, the movement of the activity rod 25 can drive the second connecting plate 26 to move accordingly, and further the mutual approach and separation of the two groups of second connecting plates 26 can be realized, thus facilitating the tightening of the cable through the hooks 11.

[0028] Furthermore, a protection mechanism is provided on the surface of the hook seat 1. The protection mechanism includes a connecting rod 3. The connecting rod 3 is fixedly connected to the surface of the hook seat 1. One end of the connecting rod 3 away from the hook seat 1 is fixedly connected with a connecting block 31. A fixing rod 32 is fixedly connected to the surface of the connecting block 31. A spring 33 is fixedly connected to the inner wall of the fixing rod 32. One end of the spring 33 away from the fixing rod 32 is fixedly connected with a telescopic rod 34. Through the setting of the spring 33, the telescopic rod 34 can move inside the fixing rod 32 during wire tightening, and the spring 33 can be deformed. The setting of the spring 33 can play a buffering role, reduce the impact force generated during wire tightening, and protect the hook seat 1 and the hook 11 from damage.

[0029] Furthermore, the connecting rod 3 is movably connected to the inside of the second connecting plate 26, and the telescopic rod 34 is movably connected to the inside of the fixing rod 32. One end of the telescopic rod 34 away from the spring 33 is fixedly connected to the second connecting plate 26. By connecting the telescopic rod 34 and the second connecting plate 26, the connecting rod 3 and the connecting block 31 can move stably during wire tightening.

[0030] Working principle: When in use, the motor 23 is electrically connected by an external power supply. The staff starts the motor 23 by pressing the switch. The motor 23 rotates to drive the forward and reverse screw rod 22 to rotate. The moving block 24 is limited by the limiting block 27 and the limiting groove 28, and will move inside the moving groove 21 under the action of the forward and reverse screw rod 22, realizing the sliding of the limiting block 27 on the surface of the limiting groove 28. Furthermore, the movable rod 25 moves through the rotating shaft, and the second connecting plate 26 can drive the hook seat 1 and the hook 11 to move vertically, so that the distance between the hooks 11 changes, and the tightening of the cable can be realized;

[0031] When tightening the cable through the hook 11, the hook 11 is subjected to a pulling force, which causes the connecting rod 3 to move inside the second connecting plate 26. Furthermore, the connecting block 31 causes the fixing rod 32 to move on the surface of the telescopic rod 34 under the action of the connecting rod 3, so that the spring 33 is deformed. Through the action of the spring 33, the impact force and pulling force generated during wire tightening can be reduced, and the damage to the hook seat 1 and the hook 11 can be reduced.

[0032] The above is only the preferred embodiment of the present invention, and does not impose any form of limitation on the present invention; any ordinary technical personnel in this industry can smoothly implement the present invention according to the instructions in the drawings and the above; however, any minor changes, modifications and evolutions made by those familiar with the technology within the scope of the technical solution of the present invention using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essence of the present invention still fall within the protection scope of the technical solution of the present invention.
