Description

Technical Field

[0001] This utility model relates to the technical field of bridge inspection equipment, specifically a self-climbing inspection device for suspension bridge hangers. Background Technology

[0002] As an important form of modern long-span bridge, suspension bridges use suspenders, which are key force-transmitting components connecting the main cable and the bridge deck system. They are subjected to alternating loads and wind and rain erosion over a long period of time, making them prone to fatigue cracks, corrosion, and wire breakage, requiring regular inspection and maintenance. Currently, the inspection of suspension bridge hangers mainly relies on three methods: First, erecting scaffolding or using bridge inspection vehicles. This method requires traffic interruption, is time-consuming, labor-intensive, and costly, and the work under the bridge is limited by space and wind, resulting in low safety. Second, manual climbing inspection. Inspectors need to climb the hangers directly with the aid of safety ropes, which is labor-intensive, extremely dangerous, and the efficiency and quality of inspection are greatly affected by the personnel's skills. Third, close-range observation by drones. Although this method is flexible, it has poor wind resistance, short flight time, difficulty in carrying heavy inspection equipment (such as magnetic particle flaw detectors), insufficient image stability, and short flight time, making it difficult to obtain high-definition and comprehensive inspection data.

[0003] Therefore, there is an urgent need for an automated device capable of autonomously, stably, and safely climbing along suspension bridge gantry and carrying inspection equipment for comprehensive testing, in order to overcome the shortcomings of the aforementioned methods. To this end, we propose a self-climbing inspection device for suspension bridge gantry. Utility Model Content

[0004] The purpose of this invention is to provide a self-climbing detection device for suspension bridge hangers, which can solve the problems of low efficiency, high risk, high cost and great environmental constraints of the existing detection methods mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-climbing detection device for suspension bridge suspenders, comprising a suspender body and a climbing mechanism. The climbing mechanism includes a first collar, a second collar on one side of the first collar, and an insert block fixedly provided on the outer wall of the second collar near the first collar. The outer wall of the first collar has an installation groove for the insert block to be inserted into, and the insert block is fixed by a locking pin. A fixing frame is fixedly provided on the outer walls of the first collar and the second collar, and a fixing seat is provided inside the fixing frame. A roller is rotatably connected inside the fixing seat, and the roller is driven by a small motor. A detection mechanism for detecting the suspender body is installed on the top of the climbing mechanism.

[0006] By adopting the above technical solution, it is possible to achieve self-climbing detection of the boom body.

[0007] Preferably, limiting sliders are fixed on both sides of the outer wall of the fixed base, and the inner side wall of the fixed frame is provided with a sliding groove for the limiting sliders to slide, and the sliding groove is adapted to the limiting sliders.

[0008] By adopting the above technical solution, the stability of the fixed base during use can be improved.

[0009] Preferably, a magnetic block is fixedly installed at the middle position of the outer side wall of the roller, the magnetic block is embedded inside the roller, and the magnetic block is a neodymium iron boron permanent magnet.

[0010] By adopting the above technical solution, the stability of the roller during climbing can be improved.

[0011] Preferably, the detection mechanism includes two horizontally symmetrical guide rails, with an electric slider slidably connected to the outer wall of the guide rails, and a rotating gimbal fixedly installed at the bottom of the electric slider.

[0012] By adopting the above technical solution, it is possible to inspect the main body of the boom.

[0013] Preferably, there are four fixing frames, the four locking pins are equidistantly distributed, and an adjustment mechanism is installed between the fixing frame and the fixing seat.

[0014] By adopting the above technical solution, the stability of the fixed base during climbing can be improved.

[0015] Preferably, the adjusting mechanism includes a threaded rod, one end of which is fixedly provided with a handwheel, and the other end of which is fixedly provided with a ratchet. A pawl is rotatably connected to the outer wall of the fixed seat near the ratchet. One end of the pawl is fixedly provided with a lever, and a torsion spring is elastically connected between the pawl and the fixed seat.

[0016] By adopting the above technical solution, it is possible to inspect the main body of the suspension rod of different specifications.

[0017] Compared with the prior art, the beneficial effects of this utility model are: Firstly, by setting up a boom body, a climbing mechanism, and a detection mechanism, the small motor in the climbing mechanism drives the rollers, and under the attraction of the magnetic block and the boom body, it has strong resistance to wind interference and a smooth climbing process. This not only realizes the stable and automated climbing detection of the boom body, but also improves the detection quality and efficiency of the device when detecting the boom body.

[0018] Secondly, by setting up a boom body, a climbing mechanism, and an adjustment mechanism, the handwheel in the adjustment mechanism drives the threaded rod. With the ratchet and pawl engaged, the climbing mechanism can adapt to the boom body of different diameters and perform stable automatic climbing by adjusting its own position. This not only improves the applicability of the device but also enhances its practicality. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0026] Please see Figures 1-3The diagram illustrates a self-climbing detection device for suspension bridge suspenders, comprising a suspender body 1 and a climbing mechanism 2. The climbing mechanism 2 includes a first collar 201, a second collar 202 on one side of the first collar 201, and an insert 2021 fixedly mounted on the outer wall of the second collar 202 near the first collar 201. The outer wall of the first collar 201 has an installation groove 2011 for inserting the insert 2021, which is fixed by a locking pin 203 inserted from the bottom of the first collar 201 into the installation groove 2011, thus fixing the first collar 201 and the second collar 202 together. Four fixing frames 204 are fixedly mounted on the outer walls of the first collar 201 and the second collar 202, with the four locking pins 203 evenly spaced. A fixing seat 205 is located inside the fixing frame 204, penetrating the first collar 201. Inside the second ring 202, both sides of the outer wall of the fixing base 205 are fixed with limiting sliders 2051. The limiting sliders 2051 have a T-shaped cross-section. The inner side wall of the fixing frame 204 has a groove 2041 for the limiting sliders 2051 to slide. The groove 2041 is adapted to the limiting sliders 2051. A roller 206 is rotatably connected inside the fixing base 205. A magnetic block 2061 is fixedly installed at the middle position of the outer side wall of the roller 206. Block 2061 is embedded inside roller 206. Magnetic block 2061 is a neodymium iron boron permanent magnet. Roller 206 is driven by a small motor 207. The small motor 207 is fixedly installed inside the mounting bracket 204. The output shaft of the small motor 207 is connected to the roller 206. The attraction force of magnetic block 2061 is less than the torque of small motor 207 driving roller 206. A storage battery is installed inside the first ring 201 and the second ring 202. The top of the climbing mechanism 2 is equipped with a detection mechanism 3 for detecting the boom body 1. The detection mechanism 3 includes two horizontally symmetrical guide rails 301. The two guide rails 301 are fixedly connected to the first ring 201 and the second ring 202 respectively. An electric slider 302 is slidably connected to the outer wall of the guide rail 301. A rotating gimbal 303 is fixedly installed at the bottom of the electric slider 302. The rotating gimbal 303 is equipped with a camera, sensor and controller program. The electric slider 302 drives the rotating gimbal 303 to rotate around the guide rail 301 to detect the boom body 1. When inspecting the boom body 1, firstly, the first ring 201 and the second ring 202 of the climbing mechanism 2 are fitted onto the boom body 1. Then, the insert block 2021 at one end of the second ring 202 is inserted into the mounting groove 2011 at one end of the first ring 201, and the assembled first ring 201 and second ring 202 are fixed by the locking pin 203. Next, the small motor 207 is started to start the roller 206. Through the attraction of the magnetic block 2061 to the outer surface of the boom body 1, the roller 206 rotates and drives the boom to climb. Mechanism 2 and detection mechanism 3 automatically climb on the boom body 1, and drive the rotating gimbal 303 to perform a 360-degree rotation scan around the boom body 1 under the guidance of guide rail 301 via electric slider 302. Then, through the small motor 207 in climbing mechanism 2 driving roller 206, and with the magnetic block 2061 adsorbing the boom body 1, the device has strong resistance to wind interference and the climbing process is stable. This not only realizes the stable and automated climbing detection of the boom body 1, but also improves the detection quality and efficiency of the device when detecting the boom body 1.

[0027] Please see Figures 1-4 In the figure, an adjustment mechanism 4 is installed between the fixed frame 204 and the fixed seat 205. The adjustment mechanism 4 includes a threaded rod 401, which is threadedly connected to the fixed frame 204. One end of the threaded rod 401 is rotatably connected to the inside of the fixed seat 205. A handwheel 4011 is fixed at one end of the threaded rod 401, and a ratchet 402 is fixed at the other end of the threaded rod 401. A pawl 403 is rotatably connected to the outer wall of the fixed seat 205 near the ratchet 402. A paddle block 4031 is fixed at one end of the pawl 403. The pawl 403 meshes with the ratchet 402. A torsion spring 404 is elastically connected between the pawl 403 and the fixed seat 205. When inspecting boom bodies 1 of different diameters, the position of roller 206 is adjusted. Turning handwheel 4011 causes threaded rod 401 to rotate inside fixed frame 204, pushing fixed seat 205, limit slider 2051, and roller 206 closer to boom body 1 under the limit of slide groove 2041. Simultaneously, the rotation of threaded rod 401 drives ratchet 402 to rotate, and the rotation of ratchet 402 pushes pawl 403 to swing to one side, compressing torsion spring 404 until roller 206 abuts against the outer wall of boom body 1. Then, the drive of threaded rod 401 is stopped, and the torsion spring 404 springs back to its original position. Under potential energy, the pawl 403 engages with the ratchet 402 again to prevent the fixed seat 205 from shifting back. When it is necessary to adjust the engagement state of the pawl 403 and the ratchet 402, the position of the pawl 403 can be controlled by moving the lever 4031. Then, through the drive of the threaded rod 401 by the handwheel 4011 in the adjustment mechanism 4, in the state of engagement between the ratchet 402 and the pawl 403, the climbing mechanism 2 can adapt to the lifting rod body 1 by adjusting its own position and stably perform automatic climbing when detecting lifting rod bodies 1 of different diameters. This not only improves the applicability of the device but also enhances its practicality.
