[0036] The bottom end of the sliding frame 2 is fixedly connected with a support frame 3 to provide support force for the U-shaped bracket 1, thereby preventing the U-shaped bracket 1 from leaning toward both ends after being stressed. The roller frame 5 fixedly connected inside the bracket 1 can guide the CFRP cable through the roller tube installed on its surface to assist in completing the traction operation of the CFRP cable. Through the reinforcement beam 4 connected between a pair of support frames 3, a pair of support frames 3 can be connected, thereby fixing and limiting the support frame 3 to prevent the support frame 3 from being displaced after being stressed.

[0040] like Figures 1 to 3 As shown, a driving motor 9 is fixedly connected inside the reinforcement beam 4. The driving motor 9 is located directly below the adjusting disk 8. The driving shaft of the driving motor 9 is snap-connected with the bottom end of the adjusting disk 8. The driving motor 9 fixedly connected inside the reinforcement beam 4 can drive the adjusting disk 8 to rotate, thereby adding a height adjustment method for the U-shaped bracket 1, meeting the demand for adjusting the height of the U-shaped bracket 1 in different environments of the entire equipment.

[0041] like Figure 2 , Figure 3 and Figure 5As shown, the lateral support mechanism 10 includes a support arm 11 fixedly connected to a pair of support frames 3, one end of the support arm 11 is fixedly connected to a support base pad 12, the bottom end of the support base pad 12 is movably connected to a No. 1 universal ball 13, an adjusting screw 15 is rotatably installed inside the support base pad 12, one end of the adjusting screw 15 is fixedly connected to a positioning pad 14, the positioning pad 14 is located at the bottom end of the support base pad 12, the support arm 11 fixedly connected to the pair of support frames 3 can cooperate with the support base pad 12 fixedly connected to one end of the support arm 11 to provide lateral support force for the support frame 3, thereby preventing the CFRP cable from being pulled during the traction process and causing the entire equipment to tip over, the bottom ends of the pair of support frames 3 are fixedly connected to an extension base plate 23, the extension base plate 23 and the support frame 3 are an integral structure, and the extension base plate 23 is an integral structure with the support frame 3. A No. 2 universal ball 16 is movably connected to the bottom end of the base plate 23, and a positioning base pad 17 is rotatably installed at the bottom end of the extended base plate 23. The adjustment plate of the positioning base pad 17 is located at the top of the extended base plate 23. A pair of extended base plates 23 fixedly connected to the bottom end of the support frame 3 can enhance the bottom end area of ​​the support frame 3, thereby improving the stability of the support frame 3. The No. 2 universal ball 16 movably connected to the bottom end of the extended base plate 23 is convenient for cooperating with the No. 1 universal ball 13 movably connected to the bottom end of the support base pad 12 to move the entire device to meet the traction requirements of the CFRP cable. At the same time, the positioning base pad 17 and the positioning support pad 14 fixedly connected to one end of the adjusting screw 15 inside the support base pad 12 are rotatably installed at the bottom end of the extended base plate 23, so that the entire device can be fixed to meet the guiding and supporting requirements of the CFRP cable.

[0042] like Figure 3 and Figure 5 As shown, the bottom ends of the support base pad 12 and the extended base plate 23 are flush with each other, and the bottom end of the support arm 11 is inclined away from the support frame 3. The flush support base pad 12 and the extended base plate 23 ensure the overall stability of the entire equipment placed on the construction platform.

[0043] The working principle provided by the utility model is to place the CFRP cable that needs to be towed in the roller frame 5, and use the guide roller 18 movably installed on the outer wall of the roller frame 5 to guide and support the CFRP cable. According to the towing direction requirement of the CFRP cable, the entire device can be moved to adjust the towing direction. When the CFRP cable needs to pass through the hole of the cable fixing mechanism, the adjusting disk 8 at the bottom end of the threaded rod 7 is rotated according to the hole height of the cable fixing mechanism to adjust the height of the U-shaped bracket 1, so that the height of the CFRP cable matches the hole of the cable fixing mechanism, thereby avoiding the CFRP cable and the cable fixing mechanism from being scratched and damaged.

[0044] During the use of the equipment, the driving motor 9 fixedly connected inside the reinforcement beam 4 can drive the adjustment disk 8 to rotate, thereby adding a way to adjust the height of the U-shaped bracket 1, meeting the needs of adjusting the height of the U-shaped bracket 1 in different environments of the entire equipment.
