Description

Technical Field

[0001] This application relates to the field of cable-stayed bridge saddle technology, and specifically discloses a cable-stayed bridge saddle for a short tower. Background Technology

[0002] A cable saddle is a supporting structure that allows suspension cables or stay cables to pass through the top of a tower, and it is used in structures such as bridges. For example, it is used in low-tower cable-stayed bridges, which combine the characteristics of cable-stayed bridges and continuous beams, exhibiting a balance of rigidity and flexibility.

[0003] The cable saddle, used in low-tower cable-stayed bridges, is an important component of such bridges. It is usually located between the bridge tower and the cable, and plays a role in supporting and transmitting cable forces.

[0004] Existing cable saddles for low-tower cable-stayed bridges increase the anti-slip capability between the saddle and the bridge by providing additional friction. For example, a cable saddle for a low-tower cable-stayed bridge disclosed in Chinese Patent Publication No. CN220619790U uses a positioning ring, mounting plate, bolts, nuts, and sleeves to restrict the position of the cable on the cable-shaped body, thus avoiding the problem of reduced anti-slip capability between the saddle and the cable. Simultaneously, by incorporating an external threaded tube, sealing ring, protective tube, limiting ring, and internal threaded tube, it completes the sealing and protection of the cable, preventing the cable from being exposed for extended periods and slowing down the rate of corrosion.

[0005] However, since the external and internal threaded tubes are connected on the outside, although this avoids corrosion of the internal cable, the connection between the external and internal threaded tubes can still be corroded. In subsequent inspections, it is difficult to directly separate the external and internal threaded tubes.

[0006] This invention provides a cable saddle for a low-tower cable-stayed bridge to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to solve the problem that the connection between the external and internal threaded pipes of the cable saddle in traditional low-tower cable-stayed bridges is still subject to corrosion, making it difficult to directly separate the external and internal threaded pipes during subsequent inspection.

[0008] To achieve the above objectives, the basic solution of this utility model provides a cable saddle for a low-tower cable-stayed bridge, including a cable-shaped body, connecting plates fixed to both ends of the cable-shaped body, and several cables disposed within the cable-shaped body. Each connecting plate is fixed with a reinforcing rib connected to the cable-shaped body, and positioning rings are fixed between the cables. Each connecting plate is bolted to an mounting plate, and each mounting plate is fixed with a connecting sleeve that wraps around the cable. A connecting ring sleeve is coaxially fixed to the connecting sleeve. It also includes a second connecting sleeve that can abut against the free end of the first connecting sleeve and be used to wrap the cable. The connecting ring sleeve has a receiving ring groove at one end facing the second connecting sleeve. The end of the second connecting sleeve is rotatably connected to a connecting sleeve that can extend into the receiving ring groove. The receiving ring groove has an internal thread, and the connecting sleeve has an external thread that can mesh with the internal thread. The second connecting sleeve is also provided with a stop plate that can abut against the positioning ring. The stop plate has several through holes for the cable to pass through.

[0009] Furthermore, the end of the connecting ring sleeve facing the second connecting sleeve extends to the same side of the end of the first connecting sleeve.

[0010] Furthermore, the receiving annular groove includes, in sequence along the direction of insertion of the connecting sleeve, a wrapping section one, a pressing section and a wrapping section two. The inner diameter of the wrapping section one is larger than the inner diameter of the wrapping section two. The pressing section is inclinedly arranged and inclinedly connected between the wrapping section one and the wrapping section two. The connecting sleeve is formed with a connecting part one and a connecting part two that respectively fit with the wrapping section two and the pressing section.

[0011] Furthermore, the internal thread is formed on the clamping section, and the external thread is formed on the second connecting part.

[0012] Furthermore, the internal thread is formed on the pressing section and extends to its end near the second wrapping section, and the external thread is formed on the connecting part and extends to its end near the first connecting part.

[0013] Furthermore, the end of the connecting sleeve extending into the connecting ring sleeve has several internal threaded holes, and the connecting ring sleeve has several internal threaded holes that can be aligned with the internal threaded holes after the connecting sleeve 2 and the connecting sleeve 1 are pressed together. The connecting ring sleeve is also provided with several bolts that can be screwed into the internal threaded holes 1 and the internal threaded holes 2 respectively.

[0014] Furthermore, the second connecting sleeve is provided with a limiting ring platform, and a limiting ring groove is opened on the inner side of the connecting sleeve for the limiting ring platform to slide.

[0015] The principle and effect of this solution are as follows: 1. Compared with the prior art, in the long-term use of this utility model, because the main connection parts of the connecting ring and the connecting sleeve are on the internal and external threads of the compression section and the second connecting part, they are wrapped inside the connecting ring. Therefore, it can prevent rainwater from entering and is not easy to rust. This solves the problem that the connection parts of the external and internal threaded pipes of the cable saddle of the traditional low tower cable-stayed bridge are still corroded, and it is difficult to directly separate the external and internal threaded pipes during subsequent inspection.

[0016] 2. Compared with the prior art, the present invention uses connecting plates, mounting plates, connecting sleeve one, and connecting sleeve two to restrict the position of the cable on the cable body, thus avoiding the problem of reduced anti-slip ability between the cable saddle and the bridge cable.

[0017] 3. Compared with the prior art, the present invention has an internal threaded hole one and an internal threaded hole two between the connecting sleeve and the connecting ring sleeve. When the internal threaded hole one and the internal threaded hole two are aligned, the connecting ring sleeve and the connecting sleeve are fixed by bolts. The bolts can tighten the connecting ring sleeve and the connecting sleeve. Attached Figure Description

[0021] The reference numerals in the accompanying drawings of the instruction manual include: cable-shaped body 1, connecting plate 2, connecting sleeve one 3, connecting sleeve two 4, cable 5, connecting ring sleeve 6, connecting sleeve 7, bolt 8, clamping section 9, connecting part two 10, connecting part one 11, abutment plate 12, positioning ring 13, limiting ring platform 14.

[0022] A cable saddle for a low-tower cable-stayed bridge, implemented as follows: Figure 1 and Figure 2 As shown: It includes a cable-shaped main body 1, connecting plates 2 fixed at both ends of the cable-shaped main body 1, and several cables 5 installed inside the cable-shaped main body 1. Each connecting plate 2 is equipped with several reinforcing ribs connected to the cable-shaped main body 1, and each cable at both ends of the cable-shaped main body 1 is fixed with a positioning ring 13.

[0023] In this embodiment, on the cable-shaped main body 1, a mounting plate is fixedly installed on the outside of the connecting plate 2 by bolts 8. A connecting sleeve 3 that wraps around the cable 5 is fixed on the mounting plate, and a connecting ring sleeve 6 is coaxially fixed on the outside of the connecting sleeve 3. At the same time, several reinforcing ribs connected to the connecting sleeve 3 are also fixed on the mounting plate.

[0024] like Figure 2As shown, the cable saddle of the low tower cable-stayed bridge also includes a second connecting sleeve 4. The right end of the second connecting sleeve 4 can abut against the left end of the first connecting sleeve 3, and the cable 5 behind is wrapped by the second connecting sleeve 4.

[0025] A rotatable connecting sleeve 7 is installed at the right end of the connecting sleeve 2 4. The connecting ring sleeve 6 faces the end of the connecting sleeve 2 4, that is, the left end, and has a receiving ring groove. The connecting sleeve 7 can extend into the receiving ring groove and abut against the inner end face of the receiving ring groove. At the same time, a stop plate 12 is also formed inside the connecting sleeve 2 4. Specifically, in this embodiment, the stop plate 12 is formed at the right end of the connecting sleeve 2 4. The stop plate 12 has several through holes for the pull cable 5 to pass through. When the connecting sleeve 2 4 and the connecting sleeve 1 3 are pressed together, the stop plate 12 abuts against the positioning ring 13.

[0026] In this embodiment, the left end of the connecting ring sleeve 6 extends beyond the left end of the connecting sleeve 3. Furthermore, the connecting sleeve 3 has the same diameter as the connecting sleeve.

[0027] A limiting ring platform 14 is formed on the connecting sleeve 2 4, and a limiting ring groove is opened in the connecting sleeve 7 for the limiting ring platform 14 to slide inside.

[0028] Furthermore, the receiving annular groove includes, in sequence, a wrapping section one, a pressing section 9 and a wrapping section two along the direction in which the connecting sleeve 7 extends. The inner diameter of the wrapping section one is larger than the inner diameter of the wrapping section two. The pressing section 9 is inclinedly arranged and inclinedly connected between the wrapping section one and the wrapping section two. The connecting sleeve 7 is formed with a connecting part one 11 and a connecting part two 10 that respectively fit with the wrapping section two and the pressing section 9.

[0029] Furthermore, an internal thread is formed within the receiving annular groove, and an external thread that engages with the internal thread is formed on the outside of the connecting sleeve 7. Specifically, the thread is formed on the clamping section 9 and extends to its end near the second wrapping section, while the external thread is formed on the connecting part and extends to its end near the first connecting part 11. like Figure 2 As shown, the connecting sleeve 7 extends into the end of the connecting ring sleeve 6 and has two internal threaded holes. The connecting ring sleeve 6 has two internal threaded holes that can be aligned with the internal threaded holes after the connecting sleeve 2 4 and the connecting sleeve 1 3 are pressed together. The connecting ring sleeve 6 is also provided with several bolts 8 that can be screwed into the internal threaded holes 1 and the internal threaded holes 2 respectively.

[0030] In this embodiment, as Figure 2 As shown, when connecting sleeve 3 and connecting sleeve 4 are pressed together, the left end of connecting ring sleeve 6 extends behind the right end of connecting sleeve 4, wrapping around connecting sleeve 7. The right end of connecting sleeve 7 wraps around the left end of connecting sleeve 3, achieving a complete seal and isolation.

[0031] In use, the connecting plate 2 and the mounting plate are first installed using bolts 8. After the connecting sleeve 3 is installed, the connecting sleeve 4 is aligned with the connecting sleeve 3, and the end of the connecting sleeve 7 is inserted into the receiving groove of the connecting ring sleeve 6. Based on the alignment of the connecting sleeve 4 and the connecting sleeve 3, the connecting sleeve 7 is screwed into the receiving groove until the end of the connecting sleeve 7 abuts against the inner end of the receiving groove. At this time, the first internal thread hole and the second internal thread hole are aligned. Then, the connecting ring sleeve 6 and the connecting sleeve 7 are fixed using bolts 8. Bolts 8 can tighten the connecting ring sleeve 6 and the connecting sleeve 7. During long-term use, since the main connection parts of the connecting ring sleeve 6 and the connecting sleeve 7 are on the internal and external threads of the pressing section 9 and the connecting part 10, they are wrapped inside the connecting ring sleeve 6. Therefore, rainwater can be blocked from entering, and corrosion is not easy to occur.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
