Description

Technical Field

[0001] This utility model relates to the field of bridge inspection technology, specifically a bridge cable tension testing device. Background Technology

[0002] Bridge cables are key components of long-span bridges. They are mostly made of high-strength steel wires, steel strands and other materials, and are manufactured through a stranding process. They are also treated with anti-corrosion methods such as galvanizing and painting. In suspension bridges and cable-stayed bridges, they bear the important responsibility of transferring loads and maintaining the stability of the bridge structure, ensuring that the bridge can span a large span.

[0003] In existing technologies, cables, as the core load-bearing components of suspension bridges, cable-stayed bridges, and other structures, have tension parameters that directly affect the safety and lifespan of the bridge. Therefore, tension testing of manufactured cables is a crucial step in quality control. Currently, the mainstream testing technology mostly adopts the clamping and stretching method, which involves fixing both ends of the cable and collecting tension data in real time using sensors during the stretching process. However, bridge cables have a wide variety of specifications, with diameters ranging from tens of millimeters to hundreds of millimeters. If the clamping force is insufficient, it may not only cause the cable to slip unexpectedly during the testing process, leading to safety accidents, but also cause uneven stress on the cable due to insecure clamping, resulting in the collected tension data deviating significantly from the true value. Ultimately, this leads to a huge discrepancy between the test results and the actual service performance of the cable. To address this, we propose a bridge cable tension testing device. Utility Model Content

[0004] The purpose of this invention is to provide a bridge cable tension detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge cable tension detection device, comprising a first fixing plate, multiple second fixing plates fixedly connected to the outside of the first fixing plate, a detection component fixedly connected to the top of the first fixing plate, a sliding groove inside the second fixing plate, two sliders slidably connected inside the sliding groove, an mounting plate fixedly connected to one side of the multiple sliders, a driving component fixedly connected to the top of the mounting plate, a limiting groove on the top of the mounting plate, a connecting plate slidably connected inside the limiting groove, two support rods fixedly connected to the top of the mounting plate, an outer ring fixedly connected to the top of the connecting plate, a connecting ring fixedly connected to the top of the two support rods, multiple sliding grooves inside the connecting ring, sliding blocks slidably connected inside the sliding grooves, a sliding plate fixedly connected to the outside of every two sliding blocks, an arc-shaped plate fixedly connected to the outside of the sliding plate, multiple fitting strips fixedly connected to the outside of the arc-shaped plate, multiple connecting blocks fixedly connected to the outside of the arc-shaped plate, rotating strips rotatably connected to the outside of the connecting blocks, and a connecting strip rotatably connected to the inside of every two rotating strips.

[0006] The detection component has a mounting block fixedly connected to its top, and the mounting block has a detector fixedly connected to its top.

[0007] The drive assembly has a motor fixedly connected inside, a threaded rod fixedly connected to the output end of the motor, and a limit plate fixedly connected to the top of the mounting plate.

[0008] Among them, the bottom of the fixed plate 2 is fixedly connected to the support column 1, and the bottom of the fixed plate 1 is fixedly connected to two support columns 2.

[0009] Among them, a cylinder is fixedly connected to the bottom of the fixed plate, a push block is fixedly connected to the output end of the cylinder, two pull plates are rotatably connected inside the push block, and a limit block is fixedly connected to the outside of the pull plates.

[0010] The sliding block is externally slidably connected to the inside of the connecting ring, and the connecting strip is externally fixedly connected to the inside of the outer ring.

[0011] The threaded rod is externally threaded and connected to the inside of the connecting plate, while the motor is externally rotatably connected to the inside of the limiting plate.

[0012] This utility model has at least the following beneficial effects:

[0013] In use, when sampling and testing cables, this invention involves passing the cable through two connecting rings. The motor in the drive assembly is then activated, causing the threaded rod to rotate. This, in turn, causes the connecting plate to slide under the constraint of the limiting groove, which in turn causes the outer ring to slide. As the outer ring slides, it drives the connecting strip, rotating strip, and other components, allowing the arc-shaped plate and sliding plate to slide within the connecting ring via the sliding block. The arc-shaped plate, in conjunction with the fitting strip, firmly clamps both sides of the cable. This allows for stable clamping of bridge cables of different specifications, eliminating the safety hazard of accidental slippage during testing due to insufficient clamping force and effectively preventing safety accidents.

[0020] 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.

[0021] Example 1

[0022] Please see Figures 1 to 5This utility model provides a technical solution: a bridge cable tension detection device, including a fixing plate 1, multiple fixing plates 101 fixedly connected to the outside of the fixing plate 1, a detection component 2 fixedly connected to the top of the fixing plate 1, a sliding groove 3 inside the fixing plate 101, two sliders 301 slidably connected inside the sliding groove 3, an mounting plate 302 fixedly connected to the adjacent side of the multiple sliders 301, a driving component 4 fixedly connected to the top of the mounting plate 302, a limiting groove 5 on the top of the mounting plate 302, a connecting plate 501 slidably connected inside the limiting groove 5, two support rods 502 fixedly connected to the top of the mounting plate 302, an outer ring 503 fixedly connected to the top of the connecting plate 501, a connecting ring 6 fixedly connected to the top of the two support rods 502, multiple sliding grooves 601 inside the connecting ring 6, sliding blocks 602 slidably connected inside the sliding grooves 601, and a sliding plate 603 fixedly connected to the outside of every two sliding blocks 602. An arc-shaped plate 604 is fixedly connected to the outside of the sliding plate 603. Multiple fitting strips 605 are fixedly connected to the outside of the arc-shaped plate 604. Multiple connecting blocks 606 are fixedly connected to the outside of the arc-shaped plate 604. Rotating strips 607 are rotatably connected to the outside of the connecting blocks 606. A connecting strip 608 is rotatably connected to the inside of every two rotating strips 607. The sliding block 602 is slidably connected to the inside of the connecting ring 6. The connecting strips 608 are fixedly connected to the inside of the outer ring 503. When the outer ring 503 moves, the connecting strips 608 drive the rotating strips 607 to rotate, making the rotating strips 607 perpendicular to the outside of the connecting blocks 606. The rotation of the rotating strips 607 drives the sliding block 602 to slide in the sliding groove 601 of the connecting ring 6, thereby driving the sliding plate 603 and the arc-shaped plate 604 to move. During the movement, the arc-shaped plate 604, in conjunction with the fitting strips 605, gradually moves towards both sides of the cable, ultimately clamping and fixing the cable to prevent the cable from loosening during the testing process.

[0023] The top of the detection component 2 is fixedly connected to the mounting block 201, and the top of the mounting block 201 is fixedly connected to the detector 202. During the process of the cable being stretched, the detection component 2 detects the cable in real time through the detector 202 fixed by the mounting block 201. The detector 202 analyzes and processes the collected cable stress data and finally determines the tension of the cable, thus completing the detection of cable tension.

[0024] A motor 401 is fixedly connected inside the drive assembly 4. A threaded rod 402 is fixedly connected to the output end of the motor 401. A limit plate 403 is fixedly connected to the top of the mounting plate 302. The threaded rod 402 is externally threaded to the inside of the connecting plate 501. The motor 401 is externally rotatably connected to the inside of the limit plate 403. The motor 401 outputs power to drive the threaded rod 402 to rotate. Since the threaded rod 402 is threaded to the connecting plate 501, and the connecting plate 501 is limited by the limit groove 5, the rotation of the threaded rod 402 is converted into the linear sliding of the connecting plate 501, thereby driving the outer ring 503 to move.

[0025] The bottom of the fixed plate 101 is fixedly connected to a support column 102, and the bottom of the fixed plate 1 is fixedly connected to two support columns 103. The support columns 102 are fixedly connected to the bottom of the fixed plate 101, which serves to support the fixed plate 101 and transfer the weight of the fixed plate 101 and the components above it to the ground, ensuring the stability of the device during the testing process.

[0026] A cylinder 7 is fixedly connected to the bottom of the fixed plate 1. A push block 701 is fixedly connected to the output end of the cylinder 7. Two pull plates 702 are rotatably connected inside the push block 701. A limit block 703 is fixedly connected to the outside of the pull plate 702. After the cable clamping and fixing is completed, the cylinder 7 is started. The cylinder 7 outputs thrust to drive the push block 701 to pull upward. When the push block 701 moves upward, the pull plate 702 inside rotates accordingly. When the pull plate 702 rotates, it interacts with the slider 301 through the externally fixed limit block 703, so that the slider 301 slides to both sides in the slide groove 3 of the fixed plate 2 101.

[0027] The working principle of this utility model is as follows: When sampling and testing the produced cables, the cable to be tested only needs to be passed horizontally through the inside of the two connecting rings 6. Then, by activating the drive components 4 on both sides in conjunction with the motor 401, the motor 401 drives the threaded rod 402 to rotate. The threaded rod 402 drives the connecting plate 501 to slide through the limiting groove 5. When the outer ring 503 slides, it drives the connecting strip 608 and the rotating strip 607 to be perpendicular to the outside of the connecting block 606. Then, the arc plate 604 and the sliding plate 603 pass through the sliding block 606. 2. The cable slides inside the connecting ring 6, and the arc plate 604, together with the fitting strip 605, clamps and fixes both sides of the cable to prevent the cable from loosening during testing. Then, the cylinder 7 is activated, which drives the push block 701 to pull upward. Then, the push block 701, together with the pulling plate 702 and the limiting block 703, causes the slider 301 to slide to both sides, thereby driving the arc plate 604 to clamp the cable and pull it to both sides. Then, the detection component 2, together with the mounting block 201 and the detector 202, detects the cable being stretched and obtains the tension of the cable.

[0028] Example 2

[0029] Please see Figures 1 to 2 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that when the mounting plate 302 slides, the mounting plate 302 and the slider 301 slide inside the groove 3 opened in the second fixed plate 101, so that the second fixed plate 101 limits the sliding of the mounting plate 302.
