Therefore, they cannot be understood as limitations on the present invention.

[0031] Example 1

[0032] like Figure 1-4As shown, an electric swing span includes a horizontal truss 1, a left arm 2, a right arm 21, a first rotating rod 14, and a second rotating rod 15. A left support frame 11 is provided at the left end of the horizontal truss 1, a right support frame 12 is provided at the right end of the horizontal truss 1, and a plurality of support plates 13 are evenly spaced on the upper surface of the horizontal truss 1.

[0033] A first shaft seat 131 and a second shaft seat 132 are provided on the upper surface of the middle support plate 13, and second shaft seats 132 are provided on the upper surfaces of the support plates 13 on both sides. The first shaft seats 131 on the left and right sides are aligned, and the second shaft seats 132 on the left and right sides are aligned.

[0034] The two ends of the first rotating rod 14 are respectively installed in two opposite first shaft seats 131, and the two ends of the second rotating rod 15 are respectively installed in two opposite second shaft seats 132. The first rotating rod 14 and the second rotating rod 15 are both arranged along the length direction of the horizontal truss 1, and the high-voltage transmission cable can just be placed on the first rotating rod 14 and the second rotating rod 15;

[0035] The right side of the lower end of the left arm 2 is rotatably mounted on the right end of the upper surface of the left support frame 11, and the left side of the lower end of the right arm 21 is rotatably mounted on the left end of the upper surface of the right support frame 12, that is, the left arm 2 and the right arm 21 can be rotated open or lie flat.

[0036] There are two first rotating rods 14 , one at the front and one at the back, located in the middle of the upper surface of the horizontal truss 1 . There are two second rotating rods 15 , one at the front and one at the back, located on both sides of the upper surface of the horizontal truss 1 .

[0037] The upper surface edge of the first axle seat 131, the upper surface edge of the second axle seat 132, the upper surface of the left support frame 11, and the upper surface of the right support frame 12 are flush in the vertical height direction. When the left arm beam 2 and the right arm beam 21 are lying flat, the front ends of the left arm beam 2 and the right arm beam 21 just rest on the first axle seat 131 and the second axle seat 132 in the middle position.

[0038] Two opposing swivel seats 18 are provided at the right end of the upper surface of the left support frame 11 and the left end of the upper surface of the right support frame 12, and a rotating shaft 22 is provided at the right side surface of the lower end of the left arm 2 and the left side surface of the lower end of the right arm 21. The two ends of the rotating shaft 22 are respectively rotatably installed in the two opposing swivel seats 18, so that the left arm 2 and the right arm 21 can be rotatable.

[0039] When the left arm 2 rotates to above the left support frame 11, the angle between the left arm 2 and the horizontal truss 1 is 100-110°; when the right arm 21 rotates to above the support frame 12, the angle between the right arm 21 and the horizontal truss 1 is 100-110°.

[0040] The frame of the horizontal truss 1 is fixedly installed with the rotating disk on the upper part of the electric turntable 16, and the base at the lower part of the electric turntable 16 is fixedly installed with an assembly seat 17. When the electric turntable 16 is connected to an external power supply, the electric turntable 16 can be controlled to rotate, so that the horizontal truss 1 rotates, thereby achieving the purpose of adjusting the direction of the horizontal truss 1.

[0041] The upper ends of the left arm 2 and the right arm 21 are both arc-shaped.

[0042] In summary, the assembly seat 17 can be installed at the front end of the crane boom, so that the utility model can be raised into the air through the lifting function of the crane to facilitate the support of the power cables that need to be erected; when the electric turntable 16 rotates slowly, it can drive the horizontal truss 1, the left arm 2 and the right arm 21 above to rotate slowly;

[0043] The left arm 2 and the right arm 21 are in an open position, located at a high altitude. The three cables for transmitting high voltage electricity are placed on the second rotating rod 15 on the left, the first rotating rod 14 in the middle, and the second rotating rod 15 on the right, respectively. In this way, the first rotating rod 14 and the second rotating rod 15 play a supporting role for the high voltage cables.

[0044] The first rotating rod 14 and the second rotating rod 15 are both rotatable, so that the three cables can be easily moved forward; the first rotating rod 14 and the second rotating rod 15 are both made of insulating material and have high safety; by moving the crane arm, the left arm 2, the horizontal truss 1 and the right arm 21 can be moved under the cables, and the position of the cables can be slightly adjusted;

[0045] During the upward movement of the left arm 2, the horizontal truss 1, and the right arm 21, when the high-voltage cable is located between the left arm 2 and the right arm 21, it can smoothly fall onto the first rotating rod 14 and the second rotating rod 15. The left arm 2 and the right arm 21 play a limiting role for the transmission cable.

[0046] When the entire device is used up, the left arm 2 and the right arm 21 can be folded and stored on the upper surface of the first axle seat 131 and the second axle seat 132, so as to be easily transported to the next construction site for operation.

[0047] Implementation 2

[0048] Based on the above embodiment 1, refer to Figure 5 An electric telescopic rod 23 is provided inside the upper end of the left support frame 11 and the right support frame 12. Mounting arms 24 are welded on both sides of the top of the fixed end of the electric telescopic rod 23. The other end of the mounting arm 24 is rotatably connected to the corresponding frame body of the left support frame 11 and the frame body of the right support frame 12 through a bearing; the output end part of the electric telescopic rod 23 is rotatably connected to the corresponding left arm frame 2 and the right arm frame 21 through a rotating seat.

[0049] Based on the above, the state adjustment of the left arm 2 and the right arm 21 can be achieved by extending and retracting the electric telescopic rod 23 when the electric telescopic rod 23 is connected to a power supply, thereby making the state adjustment of the left arm 2 and the right arm 21 simple and easy to operate, saving more time and effort.

[0050] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
