[0018] The following is combined with Figure 1-5 This application is described in further detail.

[0019] An embodiment of the present application discloses a bridge pier detection device, comprising two groups of climbing frames 1, each of which is provided with an arc track 2 above the two groups of climbing frames 1. The two groups of arc tracks 2 can be spliced ​​by the climbing frames 1 to form a circular track, and multiple groups of climbing vehicles 7 are provided on the climbing frame 1. An inspection vehicle 3 is installed on the arc track 2, and an inspection head 4 is provided on the inspection vehicle 3. The inspection vehicle 3 can move along the arc track 2. Several groups of troughs are opened inside the climbing frame 1, and a guide rod 12 is installed inside the trough. One end of the guide rod 12 extends to the outside of the climbing frame 1 and is fixedly connected to a stabilizing block 8. The other end of the guide rod 12 is provided with a moving mechanism. When the inspection vehicle 3 moves along the arc track 2, the moving mechanism drives the stabilizing block 8 to move, so that the stabilizing block 8 is pressed against the bridge pier.

[0020] Furthermore, the climbing frame 1 is provided with a plurality of groups of cameras 6 installed at intervals through the connecting frame 5 . The cameras 6 can take pictures of the surface of the bridge pier and record the surface conditions of the bridge pier.

[0021] Furthermore, side plates 16 are fixedly connected to both sides of the climbing frame 1, and the side plates 16 on the two groups of climbing frames 1 are connected by bolts 15. The two groups of climbing frames 1 can be assembled or disassembled through the bolts 15.

[0022] In this embodiment, the stabilizing block 8 can actually be made of a flexible rubber material. When the stabilizing block 8 contacts the bridge pier, the stabilizing block 8 can undergo a certain deformation to match the shape of the bridge pier, and the friction force when the stabilizing block 8 made of rubber material contacts the bridge pier is relatively large. When the moving mechanism drives the stabilizing block 8 to rest against the surface of the bridge pier, it can improve the stability of the device and ensure that the inspection vehicle 3 can drive the inspection head 4 to operate stably.

[0023] It should be noted that the climbing vehicle 7 is used to drive the device body to move up and down along the bridge pier, and the detection vehicle 3 can drive the detection head 4 to move along the curved track 2, so that it can surround the bridge pier and detect the surface of the bridge pier. The power of the climbing vehicle 7 and the detection vehicle 3 can be realized by the operation of a motor or other driving mechanism. The operation technology of the climbing vehicle 7 and the detection vehicle 3 are all existing conventional technologies and will not be repeated here. The detection head 4 can use an ultrasonic detection head. Ultrasonic waves are a high-frequency wave with a frequency range of 2MHz to 50MHz. During the propagation process in the concrete structure, ultrasonic waves will encounter reflections and scatterings from different parts of the structure. These reflections and scatterings will produce different waveforms, thereby showing the situation inside the bridge pier structure.

[0024] Furthermore, the moving mechanism includes a magnetic block 11 fixedly mounted on one end of a guide rod 12, and the guide rod 12 is sleeved with a spring 10. When the stabilizing block 8 moves, the spring 10 is in an elastic force storage state, and an electromagnet 9 is fixedly connected to the inside of the slot. When the electromagnet 9 is energized, the electromagnet 9 and the magnetic block 11 repel each other.

[0025] Furthermore, a first conductive sheet 13 is fixedly connected along the arc surface in the middle of the outer surface of the arc track 2, and a second conductive sheet 14 is fixedly connected to the surface of the detection vehicle 3. The first conductive sheet 13 and the second conductive sheet 14 are both connected in series with the electromagnet 9 through wires, and the first conductive sheet 13 and the second conductive sheet 14 contact to control the power supply of the electromagnet 9.

[0026] In this embodiment, when the detection vehicle 3 drives the detection head 4 to move along the curved track 2 for detection, the first conductive sheet 13 on the detection vehicle 3 will contact the second conductive sheet 14, and the electromagnet 9 will be energized, thereby generating a repulsive force on the magnetic block 11, driving the guide rod 12 and the stabilizing block 8 to move. At this time, the spring 10 is compressed, and the stabilizing block 8 can rest against the surface of the bridge pier, thereby improving the stability of the detection head 4 during movement and detection.

[0027] In this embodiment, after the detection head 4 completes the inspection of the bridge pier, the detection vehicle 3 can be used to drive the detection head 4 to move to the initial position. At this time, the first conductive plate 13 and the second conductive plate 14 on the detection vehicle 3 are separated, the electromagnet 9 is powered off, and the compressed spring 10 is extended, driving the stabilizing block 8, the guide rod 12 and the magnetic block 11 to reset. The stabilizing block 8 no longer presses against the bridge pier, so that the overall height of the detection device can be adjusted by the climbing vehicle 7.

[0028] It should be noted that a battery assembly can be set on the outer surface or other parts of the climbing frame 1 to provide corresponding power for the detection vehicle 3, detection head 4, climbing vehicle 7, camera 6 and electromagnet 9. The circuits and related drivers involved are all existing conventional technologies and will not be repeated here.
