[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 - Figure 3The utility model provides an embodiment: a docking structure of a steel cable tower segment, including a first segment 1 and a second segment 2, wherein honeycomb holes 3 are provided inside the first segment 1 and the second segment 2, which can improve the structural strength of the first segment 1 and the second segment 2 and ensure the quality of bridge construction. At the same time, the overall weight of the first segment 1 and the second segment 2 can be reduced, so that the overall size of each first segment 1 and each second segment 2 can be made larger, and the first segment 1 and the second segment 2 are connected by an installation mechanism.

[0033] Reference Figure 3 - Figure 5 The mounting mechanism includes an L-shaped plate 4, a vertical plate 5 and a mounting bracket 7. The surfaces of the L-shaped plate 4 and the surfaces of the vertical plate 5 are provided with through holes 6 that cooperate with the fastening bolts 19. The number of through holes 6 is set to multiple, and the multiple through holes 6 are arranged in a straight line and at equal intervals on the surfaces of the L-shaped plate 4 and the surfaces of the vertical plate 5. By installing the fastening bolts 19 inside the through holes 6 at different positions, the first segments 1 and the second segments 2 of different sizes can be installed and docked. The interior of the mounting bracket 7 is provided with a mounting groove 8 that cooperates with the L-shaped plate 4 and the vertical plate 5. The L-shaped plate 4 and the vertical plate 5 are both inserted into the inner wall of the mounting groove 8. The mounting bracket 7 is fixedly connected to the first segment 1 and the second segment 2 by the fastening bolts 19. The fastening bolts 19 pass through the through holes 6 for easy disassembly and connection.

[0034] Reference Figure 3 、 Figure 4 A positioning mechanism is provided on the top of the mounting frame 7, and the positioning mechanism includes a positioning plate 9, which is arranged in a vertical state and is fixedly mounted on the top of the mounting frame 7. The number of positioning plates 9 is set to two groups, and the positioning mechanism also includes a positioning rod 10 arranged in a vertical state, and the positioning rod 10 is fixedly mounted on the surface of one group of positioning plates 9. The end of the positioning rod 10 away from the positioning plate 9 is fixedly connected to a rubber ball 11 for increasing friction, thereby improving the stability of the installation.

[0035] Reference Figure 4 The positioning mechanism also includes a sleeve 12, and a groove is provided inside the sleeve 12 to cooperate with the positioning rod 10 to improve the accuracy of installation. The sleeve 12 is fixedly mounted on the surface of another set of positioning plates 9. A rubber ring 13 for cooperating with the rubber ball 11 is fixedly connected to the inner wall of the sleeve 12 to further improve the friction and ensure the stability of the installation. The surface of the sleeve 12 is provided with air vents 14 to facilitate air flow, so that the positioning rod 10 can move freely in the sleeve 12.

[0036] Reference Figure 1 、 Figure 5A docking mechanism is provided between the L-shaped plate 4 and the vertical plate 5. The docking mechanism includes a fixed block 15, which is fixedly installed on the right side of the L-shaped plate 4. A wedge block 16 is fixedly connected to the right side of the fixed block 15 for improving the docking accuracy. The surface of the wedge block 16 is provided with an inclined surface for improving the ease of installation. The docking mechanism also includes a docking block 17, which is fixedly installed on the front side of the vertical plate 5. A docking groove 18 is provided inside the docking block 17 to cooperate with the wedge block 16.

[0037] Working principle: When in use, insert the L-shaped plate 4 and the vertical plate 5 into the mounting groove 8 inside the mounting frame 7 respectively, and then clamp the mounting frame 7 on the upper and lower sides of the first segment 1 and the second segment 2 respectively, and then pass the fastening bolts 19 through the through holes 6 at appropriate positions and tighten them, so as to fix the mounting frame 7 to the first segment 1 and the second segment 2 respectively, so as to facilitate the subsequent docking work of the cable tower segments. By inserting the fastening bolts 19 into the through holes 6 at different positions, the first segments 1 and the second segments 2 of different models and sizes can be installed and fixed, thereby improving applicability.

[0038] When the first segment 1 and the second segment 2 are docked, the two mounting frames 7 approach each other, so that the positioning rod 10 is inserted into the interior of the sleeve 12, and the rubber ball 11 on the right side of the positioning rod 10 enters the right side of the rubber ring 13. Through the cooperation of the rubber ball 11 and the rubber ring 13, the friction between the surface of the positioning rod 10 and the inner wall of the sleeve 12 is increased, thereby improving the installation stability and firmness between the two mounting frames 7, thereby improving the accuracy of docking and ensuring the quality of construction.

[0039] When the two mounting frames 7 are close to each other, they will also drive the L-shaped plate 4 and the vertical plate 5 close to each other, so that the wedge block 16 on the right side of the L-shaped plate 4 enters the docking groove 18 inside the docking block 17. Since the surface of the wedge block 16 is provided with a slope, when the wedge block 16 enters the docking groove 18, the edge of the docking groove 18 squeezes the slope of the wedge block 16, so that the wedge block 16 can accurately enter the docking groove 18. Through the cooperation of the wedge block 16 and the docking groove 18, the accuracy of the docking between the first segment 1 and the second segment 2 is further improved, thereby ensuring the quality of construction.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
