Description

Technical Field

[0001] This utility model relates to the technical field of bridge cable tensioning devices, specifically an adjustable bridge cable tensioning device. Background Technology

[0002] As a crucial component of modern transportation infrastructure, bridges' safety and stability directly impact the smooth flow of traffic and the safety of people's lives and property. Cables, as key load-bearing components in bridge structures, play a vital role in transferring loads and maintaining the overall stability of the bridge. However, due to the long-term influence of external factors such as wind loads, temperature changes, and vehicle loads, cables are prone to problems such as slackness, misalignment, or uneven stress distribution, which in turn affect the overall performance and service life of the bridge.

[0003] Traditional cable tensioning devices typically rely on manual operation, making it difficult to guarantee adjustment precision. This can easily lead to uneven cable tension, affecting the stress balance of the bridge. They also lack real-time monitoring capabilities for cable condition, failing to detect slack, misalignment, or abnormal stress in a timely manner, posing significant safety hazards. Furthermore, the adjustment process usually requires multiple people working together, making it complex and inefficient, and failing to meet the high-efficiency construction requirements of modern bridge engineering. Therefore, we propose an adjustable bridge cable tensioning device. Summary of the Invention

[0004] The purpose of this utility model is to provide an adjustable bridge cable tensioning device, which solves the problems of inconvenient adjustment after cable slack and the timeliness of stress detection.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable bridge cable tensioning device includes a mounting base, a fixing base, and a cable, wherein the top surface of the mounting base is fixedly connected to the bottom surface of the fixing base.

[0007] It also includes an adjustment section for adjusting the tension of the cable;

[0008] The linkage is used to detect the pressure on the cable surface and can also detect whether the cable is deviating or tilting during cable adjustment;

[0009] The adjusting part includes a rotating column that passes through and is rotatably connected to a fixed base. An adjusting handle is fixedly connected to the top surface of the rotating column. A large gear is passed through and fixedly connected to one end of the rotating column located inside the fixed base. The large gear meshes with a small gear. A nut is passed through and fixedly connected to the inner side of the small gear. Connecting columns are fixedly connected to both the top and bottom surfaces of the nut.

[0010] Preferably, the middle section of the cable has threads on its surface, and the cable passes through the nut and is threadedly connected to the nut.

[0011] Preferably, there are two sets of fixing seats, and the surfaces of both sets of fixing seats are fixedly connected to a connecting frame. The inner side of the connecting frame is connected to a limiting ring one and a limiting ring two.

[0012] Preferably, the limiting ring is penetrated and rotatably connected by a connecting post, and an external threaded post is fixedly connected to the surface of the connecting post.

[0013] Preferably, the external threaded post is threaded through and connected to an internal threaded sleeve, and the internal threaded sleeve is threaded through and slidably connected to the limiting ring.

[0014] Preferably, the linkage includes a pressure sensor, which passes through and is fixedly connected to the internal threaded sleeve. A connecting block is slidably connected to the inner side of the internal threaded sleeve, and an abutment wheel is provided on the inner side of the connecting block.

[0015] Preferably, a pressure rod is fixedly connected between the connecting block and the pressure sensor, and a spring is fixedly connected between the connecting block and the internal threaded sleeve.

[0016] By employing the above technical solution, this utility model provides an adjustable bridge cable tensioning device. It possesses at least the following beneficial effects:

[0017] (1) This utility model uses the rotating adjustment handle to make the rotating column rotate. When the rotating column rotates, it will drive the large gear to rotate as well. The large gear will drive the small gear that meshes with it to rotate. When the large gear drives the small gear to rotate, the nut will also rotate. However, the connecting column fixed to the surface of the nut passes through the limiting ring and is rotatably connected. The middle section of the cable has a thread, and the cable passes through the nut and is threaded to the nut. When the nut rotates, the tension of the cable is adjusted. The inner thread sleeve passes through the limiting ring and is slidably connected. The limiting ring limits the inner thread sleeve, so that the inner thread sleeve can only slide within the limiting ring. When the outer thread column rotates with the connecting column, the inner thread sleeve will move within the limiting ring. Thus, the inner thread sleeve covers the section of the cable with threads. While adjusting the tension of the cable, it can also prevent dust or concrete from the construction process from adhering to the threads of the cable and causing it to become unusable later.

[0018] (2) This utility model uses a pressure rod made of a material with a certain elasticity, and the spring will always push the connecting block tight, so that the connecting block drives the contact wheel to contact the surface of the cable. Through the force of the contact and the reaction force applied by the cable, the connecting block and the pressure rod can withstand stable pressure. If the cable deviates or tilts, the contact wheel will maintain contact with the cable through the elasticity of the spring, and transmit the pressure change to the pressure sensor through the pressure rod, so as to ensure that the device can detect and adjust the state of the cable in time, and avoid safety hazards caused by the cable tilting when adjusting the tension or when using it stably.

[0027] 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. Example

[0028] An adjustable bridge cable tensioning device, such as Figures 1-6 As shown, the device includes a mounting base 1, a fixing base 4, and a cable 5. The top surface of the mounting base 1 is fixedly connected to the bottom surface of the fixing base 4. It also includes an adjustment part 2 for adjusting the tension of the cable 5; and a linkage part 3 for detecting the pressure on the surface of the cable 5 and detecting whether the cable 5 is offset or tilted during adjustment. The adjustment part 2 includes a rotating column 21, which passes through and is rotatably connected to the fixing base 4. An adjustment handle 22 is fixedly connected to the top surface of the rotating column 21, and one end of the rotating column 21 located inside the fixing base 4 passes through and is fixedly connected to the fixing base 4. A large gear 23 meshes with a small gear 24. The mounting base 1 is installed on the surface of the bridge. Then, the cable 5 is passed through the nut 25, and the adjusting handle 22 is rotated. This causes the adjusting handle 22 to drive the rotating column 21 to rotate. As the rotating column 21 rotates, it drives the large gear 23 to rotate as well. The large gear 23 then drives the small gear 24 to rotate. The nut 25 is fixedly connected to the inner side of the small gear 24. Connecting posts 26 are fixedly connected to the top and bottom surfaces of the nut 25. The middle section of the cable 5 has threads, and the cable 5 passes through and is threadedly connected to the nut 25. When the large gear 23 drives the small gear 24 to rotate, the nut 25 also rotates. The connecting posts 26 fixedly connected to the surface of the nut 25 pass through the limiting ring 29 and are rotatably connected. The middle section of the cable 5 has threads, and the cable 5 passes through and is threadedly connected to the nut 25. This allows the tension of the cable 5 to be adjusted when the nut 25 rotates. There are two sets of fixed seats 4, and a connecting frame 28 is fixedly connected to the surface of each set of fixed seats 4. A first limiting ring 29 and a second limiting ring 210 are fixedly connected through and through the inner side of the connecting frame 28. The first limiting ring 29 is rotatably connected through the connecting post 26, and an external threaded post 27 is fixedly connected to the surface of the connecting post 26. An internal threaded sleeve 211 is threaded through and threaded to the external threaded post 27. When the nut 25 rotates, it will drive the connecting post 26 to rotate together, and when the connecting post 26 rotates, it will drive the external threaded post 27 on its surface to rotate together. Since the external threaded post 27 is threadedly connected to the internal threaded sleeve 211, and the internal threaded sleeve 211 is slidably connected through the second limiting ring 210, the second limiting ring 210 relatively limits the internal threaded sleeve 211, and the internal threaded sleeve 211 is slidably connected through the second limiting ring 210.

[0029] In this embodiment, rotating the adjusting handle 22 causes the rotating column 21 to rotate. Simultaneously, the rotating column 21 drives the large gear 23 to rotate, which in turn drives the meshing small gear 24 to rotate. When the large gear 23 drives the small gear 24 to rotate, the nut 25 also rotates. However, the connecting column 26, which is fixedly connected to the surface of the nut 25, passes through the limiting ring 29 and is rotatably connected. Furthermore, the middle section of the cable 5 has threads, and the cable 5 passes through and is threadedly connected to the nut 25. This allows the nut 25 to rotate, thereby adjusting... The tension of the cable 5 is adjusted, and the internal threaded sleeve 211 passes through the limiting ring 210 and is slidably connected, so that the limiting ring 210 relatively limits the internal threaded sleeve 211, so that the internal threaded sleeve 211 can only slide within the limiting ring 210. As the external threaded column 27 rotates with the connecting column 26, it causes the internal threaded sleeve 211 to move within the limiting ring 210, so that the internal threaded sleeve 211 fits onto the threaded section of the cable 5. While adjusting the tension of the cable 5, it can also prevent dust or concrete from the construction process from adhering to the threads of the cable 5 and making it unusable later. Example

[0030] like Figures 5-6 As shown, the linkage 3 includes a pressure sensor 31, which passes through and is fixedly connected to the internal threaded sleeve 211. A connecting block 32 is slidably connected to the inner side of the internal threaded sleeve 211. The pressure rod 35 is made of a material with a certain elasticity, and the spring 34 will always push the connecting block 32 tightly, so that the connecting block 32 drives the abutment wheel 33 to abut against the surface of the cable 5. Through the force of the abutment and the reaction force applied by the cable 5, the connecting block 32 and the pressure rod 35 can withstand stable pressure. The abutment wheel 33 is provided on the inner side of the connecting block 32. A pressure rod 35 is fixedly connected between the connecting block 32 and the pressure sensor 31. If the cable 5 deviates or tilts, the contact wheel 33 will maintain contact with the cable 5 through the elastic action of the spring 34, and transmit the pressure change to the pressure sensor 31 through the pressure rod 35. This ensures that the device can detect and adjust the state of the cable 5 in a timely manner, and avoids safety hazards caused by the tilting of the cable 5 when adjusting the tension or during stable use. A spring 34 is fixedly connected between the connecting block 32 and the internal threaded sleeve 211.

[0031] In this embodiment, the pressure rod 35 is made of a material with a certain degree of elasticity, while the spring 34 will always push the connecting block 32 tightly, so that the connecting block 32 drives the abutment wheel 33 to abut against the surface of the cable 5. Through the force of the abutment and the reaction force applied by the cable 5, the connecting block 32 and the pressure rod 35 can withstand stable pressure. If the cable 5 deviates or tilts, the abutment wheel 33 will maintain contact with the cable 5 through the elasticity of the spring 34, and transmit the pressure change to the pressure sensor 31 through the pressure rod 35, so as to ensure that the device can detect and adjust the state of the cable 5 in time, and avoid safety hazards caused by the cable 5 tilting when adjusting the tension or when using it stably.

[0032] In use, the adjustable bridge cable tensioning device of this utility model first installs the mounting base 1 onto the surface of the bridge. Then, the cable 5 is passed through the nut 25 and the adjusting handle 22 is rotated. This causes the adjusting handle 22 to drive the rotating column 21 to rotate. Simultaneously, the rotating column 21 drives the large gear 23 to rotate, which in turn drives the meshing small gear 24 to rotate. When the large gear 23 drives the small gear 24 to rotate, the nut 25 also rotates. The connecting column 26, fixedly connected to the surface of the nut 25, passes through the limiting ring 29 and is rotatably connected. Furthermore, the middle section of the cable 5 has threads, and the cable 5 passes through and is threadedly connected to the nut 25. This allows the tension of the cable 5 to be adjusted as the nut 25 rotates. As the nut 25 rotates, it drives the connecting post 26 to rotate as well. When the connecting post 26 rotates, it drives the external thread post 27 on its surface to rotate as well. Since the external thread post 27 is threadedly connected to the internal thread sleeve 211, and the internal thread sleeve 211 passes through the second limiting ring 210 and is slidably connected, the second limiting ring 210 relatively limits the internal thread sleeve 211, so that the internal thread sleeve 211 can only slide within the second limiting ring 210. As the external thread post 27 rotates with the connecting post 26, it causes the internal thread sleeve 211 to move within the second limiting ring 210, so that the internal thread sleeve 211 fits onto the threaded section of the cable 5. While adjusting the tension of the cable 5, it can also prevent dust or concrete from the construction process from adhering to the threads of the cable 5 and making it unusable later.

[0033] When the connecting column 26 rotates, it drives the external threaded column 27 on its surface to rotate as well. Since the external threaded column 27 is threadedly connected to the internal threaded sleeve 211, and the internal threaded sleeve 211 passes through the limiting ring 210 and is slidably connected, the limiting ring 210 relatively limits the internal threaded sleeve 211, so that the internal threaded sleeve 211 can only slide within the limiting ring 210. First, the pressure rod 35 is made of a material with a certain degree of elasticity, and the spring 34 will always push the connecting block 32 tightly, so that the connecting block 32 drives the abutment wheel 33 to abut against the... The surface of the cable 5, through the force of contact and the reaction force applied by the cable 5, enables the connecting block 32 and the pressure rod 35 to withstand stable pressure. If the cable 5 deviates or tilts, the contact wheel 33 will maintain contact with the cable 5 through the elastic action of the spring 34, and transmit the pressure change to the pressure sensor 31 through the pressure rod 35, ensuring that the device can detect and adjust the state of the cable 5 in a timely manner, and avoid safety hazards caused by the tilting of the cable 5 when adjusting the tension or during stable use.
