Description

Technical Field

[0001] This application relates to the field of bridge engineering inspection technology, and in particular to a mobile bridge structure inspection device. Background Technology

[0002] With the continuous advancement of infrastructure construction in my country, a large number of bridge structures built in the early stages have gradually entered a critical period of mass maintenance and upkeep. As an important node in the transportation network, the structural safety and durability of bridges are directly related to the smooth flow of transportation and the safety of public travel. Therefore, conducting a comprehensive and objective inspection and evaluation of the current use of bridges and carrying out timely maintenance and repair work for any problems found has become a core link in ensuring the safe operation of bridges.

[0003] However, the inspection and maintenance of bridge structures face unique environmental challenges. The bottom and sides of bridges are exposed, lacking direct support and working platforms, making it difficult for personnel to position themselves safely and conveniently. This poses significant difficulties for related inspection and construction work. To address this problem, specialized bridge inspection vehicles have emerged in China. Equipped with robotic arms that can carry ultrasonic flaw detectors and other equipment to inspect bridge structures, traditional bridge inspection vehicles have significant limitations in practical applications. Due to constraints such as their load capacity and size, these vehicles are relatively large, easily occupying a large amount of space on the bridge surface when inspecting smaller bridges, severely interfering with the normal driving of other vehicles, causing traffic congestion and affecting traffic efficiency. Besides inspection vehicles, manual inspection is also a commonly used method. Inspectors carry tools such as hammer testers and crack observation instruments to work on foot. While this method offers high flexibility and can adapt to some complex bridge environments, the high-altitude working environment on the exposed bridge surface poses significant safety risks for manual inspection, increasing the risk of falls and other accidents.

[0024] Reference Figure 1-4 A mobile bridge structure inspection device includes a bridge body 1. An L-shaped plate 5 is slidably connected to the outer wall of the bridge body 1. A winding roller 3 is installed at both ends of the top of the bridge body 1. Locking bolts 2 are inserted into the four corners of the winding roller 3. The winding roller 3 is connected to the bridge body 1 by the locking bolts 2. Steel wire ropes 4 are wound around the outer circumference of the winding roller 3. Two steel wire ropes 4 are fixedly connected and pass through the interior of the L-shaped plate 5. A drive motor a6 is fixedly installed inside the L-shaped plate 5. A roller 7 is fixedly connected to the output shaft of the drive motor a6. The roller 7 rolls on the inner wall of the bridge body 1. An ultrasonic flaw detector 10 is installed on the side of the L-shaped plate 5 closest to the bridge body 1. The device is driven... The rotation of the output shaft of motor a6 drives roller 7 to roll on the inner wall of bridge body 1, which in turn drives L-shaped plate 5 to move along the length of bridge body 1. With the traction assistance of take-up roller 3 and wire rope 4, the device can stably cover multiple inspection areas of bridge body 1. Compared with the traditional manual inspection method that requires working at height on the open surface, this device uses a mechanical structure to replace manual labor to reach dangerous areas, avoiding the physical exhaustion and low efficiency of manual labor carrying tools on foot. Moreover, the above structure is fixed with locking bolts 2, which is convenient for disassembly, transportation and on-site assembly. It is especially suitable for small bridges and other scenarios with limited space, and can complete the inspection work without affecting the normal passage of the bridge.

[0025] Specifically, the L-shaped plate 5 has a lifting assembly inside, which includes a threaded rod 8 rotatably connected inside the L-shaped plate 5. A lifting plate 9 is threadedly connected to the outer side of the threaded rod 8. By rotating the threaded rod 8, the lifting plate 9 can drive the ultrasonic flaw detector 10 to move up and down, thus facilitating the inspection of different height positions of the bridge body 1. The lifting plate 9 is slidably connected to the inner wall of the L-shaped plate 5. The ultrasonic flaw detector 10 is installed above the lifting plate 9. The L-shaped plate 5 has a limiting assembly inside, which includes a limiting groove 12 opened inside the L-shaped plate 5. An L-shaped rod 17 is slidably connected inside the limiting groove 12. The L-shaped plate 5 can be slidably connected to the outer wall of the bridge body 1, combined with the limiting of the limiting assembly. The wheel 14 rolls on the outer wall of the bridge body 1 to ensure the stable movement of the L-shaped plate 5 and avoid the impact of the ultrasonic flaw detector 10 on the detection effect due to the shaking of the L-shaped plate 5. The L-shaped rod 17 is fixedly connected to the frame 13 on the side close to the bridge body 1. The frame 13 is rotatably installed with a limiting wheel 14. The position of the L-shaped rod 17 and the limiting wheel 14 can be locked by setting the locking nut 15. The limiting wheel 14 can play a certain limiting role for the L-shaped plate 5, which can make the L-shaped plate 5 more stable during movement. The top of the L-shaped rod 17 is provided with an external thread, and the locking nut 15 is threadedly connected to the external thread of the L-shaped rod 17. The locking nut 15 abuts against the top of the L-shaped plate 5.

[0026] Specifically, a drive motor b11 is fixedly installed at one end of the top of the L-shaped plate 5. The rotation of the output shaft of the drive motor b11 can drive the threaded rod 8 to rotate, thereby realizing the transmission of power. The output shaft of the drive motor b11 is fixedly connected to the rotation shaft of the threaded rod 8. The limit wheel 14 rolls on the outer wall of the bridge body 1. A controller is fixedly installed on the outside of the L-shaped plate 5. The controller can control the start and stop of the electrical equipment in the device. A battery pack 16 is fixedly installed on the top of the L-shaped plate 5, which can supply power to the electrical equipment on the device. The battery pack 16 is located above the drive motor a6.

[0027] Working principle: First, the operator passes the wire rope 4 on the take-up roller 3 through the inside of the L-shaped plate 5 and uses the locking bolts 2 to install the take-up roller 3 onto both ends of the bridge body 1. Then, the position of the L-shaped rod 17 is adjusted in the limiting groove 12 so that the limiting wheel 14 is always in contact with the outer wall of the bridge body 1, and the position of the L-shaped rod 17 is locked using the locking nut 15. Then, the operator can control the drive motor b11 and drive motor a6 to start through the external controller. The rotation of the output shaft of drive motor a6 can drive the roller 7 on the bridge. The inner wall of the beam body 1 rolls, which can drive the L-shaped plate 5 to move along the length of the bridge body 1. With the traction assistance of the winding roller 3 and the wire rope 4, the device can stably cover multiple inspection areas of the bridge body 1. Compared with the traditional manual inspection method that requires working at high altitudes on the open surface, this device uses a mechanical structure to replace manual labor to reach dangerous areas, avoiding the physical exhaustion and low efficiency of manual labor carrying tools on foot. Moreover, through the rotation of the threaded rod 8, the lifting plate 9 can drive the ultrasonic flaw detector 10 to move up and down, which facilitates the inspection of different height positions of the bridge body 1.
