The lifting assembly is arranged in the transmission frame and can drive a tensioning shaft near the top to move up and down.
[0009] In order to adjust the pressure of the tensioning shaft on the cable, the lifting assembly includes: a lifting frame and a first electric cylinder. The lifting frame is fixedly connected to the top of the two sliders, and the first electric cylinder is installed on the top of the transmission frame. The output end of the first electric cylinder passes through the transmission frame and is fixedly connected to the top of the lifting frame.
[0010] In order to fix and limit the tensioned cable, the fixing mechanism includes: a force frame and a fixing plate. The force frame is fixedly connected to the top of the frame.

[0022] Embodiment 1 is as follows Figures 1 to 6 As shown, it shows a wire-tightening device for electric power construction in an embodiment of the present disclosure, including a frame 1. A groove is provided on the frame 1 and can straddle a utility pole 2. It further includes: a support frame 3, a pressing plate 4, a tensioning shaft 5 and a fixing mechanism.

There are two tensioning shafts 5. The two tensioning shafts 5 are arranged at the top of the frame 1 through a transmission mechanism and can tighten the cable. The fixing mechanism is arranged at the top of the frame 1 and can press and fix the tightened cable. Through the arrangement of the pressing mechanism, the whole frame 1 can be fixed on the utility pole 2 without the operator holding the work. Through the arrangement of the transmission mechanism and the fixing mechanism, the overhead cable can be quickly tightened and the tightened cable can be fixed and limited, facilitating the operator to operate on the position where the cable needs to be connected. Compared with the wire-tightening machine in the prior art, the present application is convenient for reducing the labor intensity of the construction personnel, reducing the risk of high-altitude operation and improving the construction safety.
[0023] As Figure 1 , Figure 2 and Figure 5 As shown, the pressing mechanism includes: a rotating plate 6, a limiting frame 7 and a driving component.

The hexagonal block 9 is fixedly connected to the other end of the driving screw 8. The operator straddles the groove provided on the machine on the utility pole 2, then presses the other end of the rotating plate 6 into the limiting groove provided on the limiting frame 7, and then twists the hexagonal block 9 to drive the driving screw 8 to rotate and move on the rotating plate 6, thereby driving the pressing plate 4 to abut against the utility pole 2 and clamping the utility pole 2 between the support frame 3 and the pressing plate 4, so as to fix the frame 1 on the utility pole 2.
[0024] As Figures 1 to 3As shown in the figure, the transmission mechanism includes: a transmission frame 10, a slider 11, a first motor 12, and a lifting component. The transmission frame 10 is fixedly connected to the top of the machine frame 1. One of the tensioning shafts 5 is rotatably connected within the transmission frame 10. There are two sliders 11, and both sliders 11 are slidably connected to the transmission frame 10. The two ends of the other tensioning shaft 5 are respectively rotatably connected to the two sliders 11. The first motor 12 is installed on one side of the transmission frame 10, and the output end of the first motor 12 penetrates the transmission frame 10 and is fixedly connected to one end of the tensioning shaft 5 near the bottom end. The lifting component is arranged within the transmission frame 10 and can drive the tensioning shaft 5 near the top end to move up and down. The lifting component includes: a lifting frame 13 and a first electric cylinder 14. The lifting frame 13 is fixedly connected to the tops of the two sliders 11. The first electric cylinder 14 is installed on the top of the transmission frame 10, and the output end of the first electric cylinder 14 penetrates the transmission frame 10 and is fixedly connected to the top of the lifting frame 13. The construction worker passes one end of the cable through the two tensioning shafts 5, and then starts the first electric cylinder 14. By driving the first electric cylinder 14, the lifting frame 13 and the slider 11 are driven to descend, thereby driving the tensioning shaft 5 near the top end to descend, so as to clamp the cable between the two tensioning shafts 5. Then, by rotating the first motor 12, the tensioning shaft 5 near the bottom end is driven to rotate, so as to convey the cable, and further tighten the overhead cable.
[0025] As Figure 1 , Figure 2 and Figure 4 shown in the figure, the fixing mechanism includes: a stress-bearing frame 15 and a fixing plate 16. The stress-bearing frame 15 is fixedly connected to the top of the machine frame 1. A fixing groove is opened at the top of the stress-bearing frame 15. The fixing plate 16 is arranged on the top of the machine frame 1 through a pressing-down component and can press and fix the cable on the top of the stress-bearing frame 15. The pressing-down component includes: a fixing frame 17 and a second electric cylinder 18. The fixing frame 17 is fixedly connected to the top of the machine frame 1. The second electric cylinder 18 is installed on the top of the fixing frame 17. The output end of the second electric cylinder 18 penetrates the fixing frame 17 and is fixedly connected to the top of the fixing plate 16. The tightened cable is located in the fixing groove. By driving the second electric cylinder 18 to drive the fixing plate 16 to descend, the cable is stably fixed in the groove when the fixing plate 16 descends, so as to fix and limit the tightened cable, which is convenient for the construction worker to operate on the part of the cable that needs to be connected.
[0026] In addition, it should be supplemented that the circumferential surfaces of the two tensioning shafts 5 are both made of rubber material, which has a high friction force and can easily convey and tighten the clamped cable. Moreover, a plurality of grooves are opened on the circumferential surface of the tensioning shaft 5, which further improves the friction force of the tensioning shaft 5 on the cable.
[0027] Embodiment 2. On the basis of Embodiment 1 of the present application, it is supplemented and explained that a working method of a power construction cable-tightening device uses a power construction cable-tightening device of the above solution, including the following steps: Step 1: Fixing. Place the groove formed on the frame 1 across the utility pole 2, such that the surface of the utility pole 2 contacts the support frame 3. Then, by an operator turning the hexagonal block 9, drive the driving screw 8 to move on the rotating plate 6. When the driving screw 8 moves, it drives the pressing plate 4 to press against the utility pole 2, thereby fixing the utility pole 2 between the support frame 3 and the pressing plate 4, and further fixing the frame 1 on the utility pole 2; Step 2: Tightening. Pass one end of the cable through between the two tensioning shafts 5. Drive the lifting frame 13 to descend by the first electric cylinder 14. When the lifting frame 13 descends, it drives the two sliders 11 and one tensioning shaft 5 near the top to descend, thereby pressing the cable between the two tensioning shafts 5. Then, drive one tensioning shaft 5 near the bottom to rotate by the first motor 12. Since the two tensioning shafts 5 press the cable, when the tensioning shaft 5 near the bottom rotates, it drives the two tensioning shafts 5 to rotate relative to each other to convey and tighten the cable; Step 3: Limiting. After the cable is tightened, drive the fixing plate 16 to descend by the second electric cylinder 18 installed on the fixing frame 17. When the fixing plate 16 descends, it presses the cable into the fixing groove formed on the force-bearing frame 15, thereby fixing and limiting the tightened cable.
