Description

Technical Field

[0001] This invention belongs to the field of bridge cables, specifically relating to a bridge cable structure that facilitates stress adjustment. Background Technology

[0002] In modern long-span bridges, cables are key load-bearing components, and their internal force state directly affects the overall stability, alignment control, and long-term service performance of the structure. To ensure reasonable stress distribution during construction and operation, precise adjustment of cable stress is often necessary.

[0003] Chinese patent CN223633794U, authorized and published on December 5, 2025, discloses a stress-adjustable bridge cable structure, which includes an upper support beam, a lower support beam, and an adjustment component. The upper support beam is located below the lower support beam, and a circular hole is formed on the surface of the upper support beam. An upper lifting head is fixedly connected to the inner wall of the circular hole on the upper support beam. An installation hole is formed on the surface of the lower support beam, and a lower lifting head is fixedly connected to the inner wall of the installation hole on the lower support beam. The adjustment component is disposed on the lower surface of the upper support beam, and the adjustment component includes a guide column. A guide column is fixedly connected to the upper surface of the lower support beam.

[0004] In the aforementioned application document, the corresponding adjustment operation can only be performed by first holding the connecting collar with one hand and pulling the shaft, and then holding and rotating the gear block with the other hand. When it is necessary to adjust the stress on both sides simultaneously, it is difficult for a single person to operate at the same time, thus affecting the normal use of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a bridge cable structure that facilitates stress adjustment, solving the problems mentioned in the background section. To achieve the above objectives, this invention provides the following technical solution: a bridge cable structure that facilitates stress adjustment, comprising an upper beam and a lower beam, wherein a connector is assembled between the upper and lower beams, and a connecting block is assembled on the side of the connector; A rotating disk is rotatably connected to the top of the lower beam. A control lever and a shaft are fixedly connected to both sides of the rotating disk, respectively. A connecting rope is sleeved on the outside of the shaft. A transmission component for transmission is assembled between the rotating disk and the connecting rope. A friction assembly is assembled between the upper beam and the lower beam. An auxiliary friction assembly is assembled on the side of the connecting component.

[0006] Preferably, the transmission component includes a hydraulic chamber 1 assembled within a rotating disk, a control lever, and a shaft. One end of the hydraulic chamber 1 is slidably connected to a sensing block via a piston, and the other end of the hydraulic chamber 1 is slidably connected to a limiting rod via a piston. A spring 1 is mounted on the side of the sensing block, and a limiting component is fixedly connected to the top of the lower beam. This design allows for single-person operation when simultaneous adjustment of stress on both sides is required, making the device easier to use.

[0007] Preferably, the end of the connecting rope away from the shaft is fixed to the connecting block.

[0008] Preferably, the end of the spring away from the sensing block is mounted on the inner wall of the hydraulic chamber.

[0009] Preferably, the shaft has a through opening, the cross-sectional shape of which is adapted to the cross-sectional shape of the limiting rod.

[0010] Preferably, the limiting member has multiple grooves, and the cross-sectional shape of the grooves is adapted to the cross-sectional shape of the limiting rod.

[0011] Preferably, the friction assembly includes a second hydraulic chamber mounted on one side of the first hydraulic chamber, a third hydraulic chamber mounted on the top of the lower support beam, and a first and a second lower pressure rod slidably connected to the bottom of the third hydraulic chamber via pistons. A first friction element is mounted on the bottom of the first lower pressure rod, and a second friction element is mounted on the bottom of the second lower pressure rod. By configuring the friction assembly, the friction force experienced by the connecting rope during movement can be increased, the moving speed of the connecting rope during stress adjustment can be reduced, and the accuracy of the adjustment results can be improved.

[0012] Preferably, the hydraulic chamber three is located at the top of the hydraulic chamber two, and is rotatably connected to and communicates with the hydraulic chamber two.

[0013] Preferably, the auxiliary friction assembly includes a hydraulic chamber four and a hydraulic chamber five respectively mounted on the top of the lower support beam. One end of the hydraulic chamber four is slidably connected to a force-bearing rod one via a piston, and the other end of the hydraulic chamber four is slidably connected to a moving rod one via a piston. One end of the hydraulic chamber five is slidably connected to a force-bearing rod two via a piston, and the other end of the hydraulic chamber five is slidably connected to a moving rod two via a piston. A friction block one is hinged to the side of the moving rod one, and a friction block two is hinged to the side of the moving rod two. By setting up the auxiliary friction assembly, the friction force on the connecting parts can be increased, the moving speed of the connecting parts during stress adjustment can be reduced, and the accuracy of the adjustment result can be further improved.

[0014] Preferably, the first force-bearing rod and the first pressure-down rod are in a fixed state, and the second force-bearing rod and the second pressure-down rod are in a fixed state.

[0015] The advantages of this application are:

[0016] (1) The bridge cable structure that facilitates stress adjustment allows the operator to hold the control lever with one hand and squeeze the sensor block with the thumb, and then rotate the control lever. In conjunction with the rotating disk, shaft, hydraulic chamber, limiting rod, spring and limiting component, the connecting rope can be released or retracted to complete the corresponding stress adjustment operation. This allows a single person to operate the device when it is necessary to adjust the stress on both sides simultaneously, making the device easier to use.

[0017] (2) When the oil in the first hydraulic chamber is squeezed by the induction block and flows, some of the oil flows into the second hydraulic chamber. In conjunction with the third hydraulic chamber, the first pressure rod and the second pressure rod, the friction element 1 and the friction element 2 move to the connecting ropes on both sides, thereby increasing the friction force on the connecting ropes when they move, reducing the moving speed of the connecting ropes when stress is adjusted, and improving the accuracy of the adjustment results.

[0018] (3) When the pressure bar 1 and pressure bar 2 move downward, they cooperate with hydraulic chamber 4, hydraulic chamber 5, force bar 1, force bar 2, moving bar 1 and moving bar 2 to make friction block 1 and friction block 2 contact with the two connecting parts respectively, thereby increasing the friction force on the connecting parts, reducing the moving speed of the connecting parts during stress adjustment, and further improving the accuracy of the adjustment result.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Example 1, please refer to Figures 1-4 A bridge cable structure that facilitates stress adjustment includes an upper support beam 100 and a lower support beam 200, with a connector 300 assembled between the upper support beam 100 and the lower support beam 200, and a connecting block 400 assembled on the side of the connector 300. A rotating disk 501 is rotatably connected to the top of the lower beam 200. A control lever 502 and a shaft 503 are fixedly connected to both sides of the rotating disk 501, respectively. A connecting rope 509 is sleeved on the outer side of the shaft 503. The end of the connecting rope 509 away from the shaft 503 is fixed to the connecting block 400. A transmission component for transmission is assembled between the rotating disk 501 and the connecting rope 509. The transmission component includes a hydraulic chamber 504 assembled within the rotating disk 501, control lever 502, and shaft 503. The operator holds the control lever 502 with one hand and squeezes the sensor block 505 with their thumb. This, in conjunction with the hydraulic chamber 504 which is slidably connected to the sensor block 505 via a piston, causes the sensor block 505 to move into the hydraulic chamber 504, squeezing the oil originally stored in the hydraulic chamber 504.

[0038] One end of the hydraulic chamber 504 is slidably connected to a sensing block 505 via a piston, and the other end of the hydraulic chamber 504 is slidably connected to a limiting rod 506 via a piston. A through opening is provided on the shaft 503, the cross-sectional shape of which matches the cross-sectional shape of the limiting rod 506. When the oil inside the hydraulic chamber 504 is compressed, it moves towards the end closest to the limiting rod 506, causing the limiting rod 506, which is slidably connected to the hydraulic chamber 504 via a piston, to move out of the hydraulic chamber 504.

[0039] A spring 507 is mounted on the side of the sensing block 505. The end of the spring 507 away from the sensing block 505 is mounted on the inner wall of the hydraulic chamber 504. A limiting member 508 is fixedly connected to the top of the lower support beam 200. The limiting member 508 has multiple grooves, and the cross-sectional shape of the grooves matches the cross-sectional shape of the limiting rod 506. When the limiting rod 506 moves, it can be removed from the grooves on the limiting member 508, thereby releasing the limiting member 508 from restricting the rotating disk 501, the operating lever 502, and the shaft 503. At this time, the rotating disk 501 and the shaft 503 can be rotated by rotating the operating lever 502, releasing or retracting the connecting rope 509 on the shaft 503, thereby completing the corresponding stress adjustment operation. In this way, when it is necessary to adjust the stress on both sides simultaneously, a single person can operate the device, making it easier to use.

[0040] In use, the operator holds the control lever 502 with one hand and squeezes the sensor block 505 with their thumb. The squeezed sensor block 505 compresses the spring 507 mounted on its side, causing it to move laterally. This, in conjunction with the hydraulic chamber 504 connected to the sensor block 505 via a piston, causes the sensor block 505 to move into the hydraulic chamber 504, squeezing the oil stored within it. This squeezing causes the oil to move towards the limiting rod 506, pulling the limiting rod 506 out of the hydraulic chamber 504. At this point, the limiting rod 506 can move out of the groove on the limiting member 508, thus canceling the rotation of the limiting member 508. The rotating disk 501, the control lever 502, and the shaft 503 are restricted. At this time, the rotating disk 501 and the shaft 503 can be rotated by rotating the control lever 502, so as to release or retract the connecting rope 509 on the shaft 503, thereby completing the corresponding stress adjustment operation. After the stress adjustment operation is completed, the operator's thumb first releases the sensing block 505. The sensing block 505, which is no longer restricted, can be reset under the action of the spring 507. The oil in the hydraulic chamber 504 can be drawn out along with the sensing block 505, which drives the limiting lever 506 to reset. The limiting lever 506 then moves into the groove on the limiting member 508, so that the limiting member 508 can re-complete the restriction on the rotating disk 501, the control lever 502, and the shaft 503.

[0041] Example 2, please refer to Figures 1-6 Based on Embodiment 1, a friction assembly 600 is installed between the upper support beam 100 and the lower support beam 200. The friction assembly 600 includes a second hydraulic chamber 601 installed on the side of the first hydraulic chamber 504, and a third hydraulic chamber 602 installed on the top of the lower support beam 200. The third hydraulic chamber 602 is located at the top of the second hydraulic chamber 601 and is rotatably connected to and communicates with the second hydraulic chamber 601. When the oil in the first hydraulic chamber 504 is squeezed by the sensing block 505 and flows, some of the oil flows into the second hydraulic chamber 601, which is installed on the side of the first hydraulic chamber 504 and communicates with the first hydraulic chamber 504. As the oil flows, it squeezes the oil originally stored in the second hydraulic chamber 601. The oil in the second hydraulic chamber 601 is squeezed, causing some of the oil in the second hydraulic chamber 601 to flow into the third hydraulic chamber 602, which is rotatably connected to and communicates with it.

[0042] The bottom of the hydraulic chamber 602 is slidably connected to a first pressure rod 603 and a second pressure rod 604 via pistons. A friction element 605 is mounted on the bottom of the first pressure rod 603, and a friction element 606 is mounted on the bottom of the second pressure rod 604. When the first and second pressure rods 603 and 604 move downwards, they cause the friction elements 605 and 606 mounted on their bottoms to move downwards together. The friction elements 605 and 606 move to the connecting ropes 509 on both sides, increasing the friction between the device and the connecting ropes 509, slowing down the movement of the connecting ropes 509, and improving the accuracy of the adjustment results.

[0043] In use, based on Embodiment 1, when the oil in hydraulic chamber 1 504 is squeezed by the sensing block 505 and flows, some of the oil flows into hydraulic chamber 2 601, which is mounted on the side of hydraulic chamber 1 504 and connected to hydraulic chamber 1 504. As the oil flows, it squeezes the oil originally stored in hydraulic chamber 2 601. The oil in hydraulic chamber 2 601 is squeezed, causing some of the oil in hydraulic chamber 2 601 to flow into hydraulic chamber 3 602, which is rotatably connected to and connected to it. The oil in hydraulic chamber 3 602 is squeezed and can be pushed closer and downward. The flow of rod 603 and the second pressing rod 604 on one side causes the first pressing rod 603 and the second pressing rod 604, which are connected to the third hydraulic chamber 602 by a piston, to extend out of the third hydraulic chamber 602 at the same time. The first pressing rod 603 and the second pressing rod 604, which are in a downward moving state, respectively drive the first friction component 605 and the second friction component 606 assembled at their bottom to move downward together. The first friction component 605 and the second friction component 606 move to the connecting ropes 509 on both sides, increasing the friction between the device and the connecting ropes 509 and slowing down the moving speed of the connecting ropes 509.

[0044] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, an auxiliary friction assembly 700 is mounted on the side of the connecting member 300. The auxiliary friction assembly 700 includes a hydraulic chamber 4 701 and a hydraulic chamber 5 702 respectively mounted on the top of the lower support beam 200. One end of the hydraulic chamber 4 701 is slidably connected to a force-bearing rod 1 703 via a piston, and the force-bearing rod 1 703 is fixed to the force-bearing rod 1 603. The other end of the hydraulic chamber 4 701 is slidably connected to a moving rod 1 705 via a piston. One end of the hydraulic chamber 5 702 is slidably connected to a force-bearing rod 2 704 via a piston, and the force-bearing rod 2 704 is fixed to the force-bearing rod 2 604. When the force-bearing rod 1 603 and the force-bearing rod 2 604 move downward, the force-bearing rod 1 603, which is in a downward moving state, can drive the force-bearing rod 1 703, which is fixed to it, to move downward together. Similarly, the force-bearing rod 2 604, which is in a downward moving state, can drive the force-bearing rod 2 704, which is fixed to it, to move downward together.

[0045] The other end of the hydraulic chamber 5 702 is slidably connected to a moving rod 2 706 via a piston. A friction block 1 707 is hinged to the side of the moving rod 1 705, and a friction block 2 708 is hinged to the side of the moving rod 2 706. When friction blocks 1 707 and 2 708 move to the side positions of the two connecting members 300 and come into contact with them, the friction force on the connecting member 300 is increased, the moving speed of the connecting member 300 during stress adjustment is reduced, and the accuracy of the adjustment result is further improved.

[0046] In use, based on Embodiments 1 and 2, when the pressing rod 1 603 and the pressing rod 2 604 move downwards, the pressing rod 1 603 in the downward moving state can drive the force-bearing rod 1 703 fixedly connected to it to move downwards together. In conjunction with the hydraulic chamber 4 701 which is slidably connected to the force-bearing rod 1 703 via a piston, the downward moving force-bearing rod 1 703 compresses the oil originally stored in the hydraulic chamber 4 701. The oil, under compression, flows towards the side closer to the moving rod 1 705, causing the moving rod 1 705, which is slidably connected to the hydraulic chamber 4 701 via a piston, to move out of the hydraulic chamber 4 701. The moving rod 1 705 in the moving state can then drive the friction block 1 707 hinged to it to move laterally; the pressing rod 1 603 in the downward moving state... Rod 2 604 can drive the force-bearing rod 2 704, which is fixedly connected to it, to move downward together. In conjunction with the hydraulic chamber 5 702, which is slidably connected to the force-bearing rod 2 704 via a piston, the downward-moving force-bearing rod 2 704 compresses the oil originally stored in the hydraulic chamber 5 702. The oil is compressed and flows towards the side closer to the moving rod 2 706, causing the moving rod 2 706, which is slidably connected to the hydraulic chamber 5 702 via a piston, to move out of the hydraulic chamber 5 702. The moving rod 2 706, which is in the moving state, can drive the friction block 2 708, which is hinged to it, to move to the side. The friction block 1 707 and the friction block 2 708 move to the side positions of the two connecting parts 300 respectively and come into contact with the connecting parts 300, increasing the friction force on the connecting parts 300.
