[0019] 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.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution:

[0021] A support device for relocating power transmission lines includes a base 1 and a support frame 2 fixed above the base 1. The base 1 has multiple rollers installed at its bottom and clamping components symmetrically arranged on both sides. The support frame 2 has a lifting cavity inside, and slots 3 are symmetrically arranged on both sides of the lifting cavity. A support seat 4 is slidably installed through the lifting cavity, and a lifting mechanism for driving the support seat 4 is provided inside. A first counterweight 5 is installed above one end of the support seat 4, extending through the slot 3, and a first baffle 6 is fixedly connected above the other end, extending through the slot 3. A storage cavity is opened inside the support seat 4 at the end away from the first counterweight 5. A slide seat 7 is slidably installed in the storage cavity. A second baffle 8 is fixedly connected above the end of the slide seat 7 away from the storage cavity. A fixing frame 9 is detachably fixed between the first baffle 6 and the second baffle 8. Multiple limiting mechanisms for fixing the wires are installed on the top of the fixing frame 9, and plug-in brackets 10 are provided at both ends.

[0022] In use, the support device is first moved to a suitable position next to the utility pole using rollers, improving its flexibility. The clamping component is then adjusted to contact the ground to stabilize the device. A suitable length of fixing frame 9 is selected based on the total number of wires distributed on the same parallel plane. The fixing frame 9 is then installed above the support base 4 and slide 7, positioned between the first baffle 6 and the second baffle 8. The lifting mechanism is then activated to raise and lower the support base 4 and slide 7 to a suitable position, until the limiting mechanism above the fixing frame 9 contacts the wire. The first counterweight 5 balances the weight at both ends of the support base 4, thus providing fixation and support. The structure is simple, easy to operate, and improves stability during use.

[0023] The clamping assembly includes a support plate 11 fixed to the outside of the base, a threaded rod 12 threadedly connected to the support plate 11, and a second counterweight 13 fixed to the bottom of the threaded rod 12. A handwheel is installed at the top of the threaded rod 12. During operation, the threaded rod 12 is rotated by the handwheel, causing the second counterweight 13 to descend to contact the ground, thereby stabilizing the base 1.

[0024] The lifting mechanism includes a servo motor 14 installed below the lifting cavity and a lead screw 15 fixedly connected to the output end of the servo motor. One end of the lead screw 15 extends through the lifting cavity, and one end of the support base 4 is provided with a first threaded hole that is helically connected to the lead screw 15. The servo motor 14 drives the lead screw 15 to rotate, and under the action of the first threaded hole, the support base 4 is driven to lift.

[0025] The bottom wall of the storage cavity has a groove, and a slide rod 16 is fixedly connected in the groove. A slider 18 and a spring 17 are sleeved on the outside of the slide rod 16. One end of the spring 17 is connected to the slider 18, and the other end is fixed to the inner wall of the groove. The bottom of the slide block 7 is fixedly connected to the slider 18. During installation, the slide block 7 can be pulled outward according to the selected length of the fixing frame 9, so that the fixing frame 9 can be clamped and fixed between the first baffle 6 and the second baffle 8. The plug-in brackets 10 at both ends can be sleeved on the outside of the first baffle 6 and the second baffle 8 respectively. The plug-in brackets 10 are fixed to the first baffle 6 and the second baffle 8 with bolts, which facilitates installation and disassembly. During disassembly, the plug-in brackets 10 are removed first. At this time, the spring 17 returns to its elasticity, thereby driving the slide block 7 to move into the storage cavity, reducing the area occupied.

[0026] The limiting mechanism includes a U-shaped frame 19 fixed on a fixed frame, a connecting rod 21 set inside the U-shaped frame 19, and limiting blocks 20 sleeved at both ends of the connecting rod 21. The surface of the connecting rod 21 is provided with a threaded groove, and the limiting block 20 is provided with a second threaded hole in the middle. In use, the limiting block 20 can be rotated according to the diameter of the wire to adjust the distance between the two limiting blocks 20. When supporting, the wire is supported between the two limiting blocks 20.
