A device for detecting piers of elevated bridges

Abstract

The present invention discloses a device for detecting elevated bridge piers, and the present invention relates to the technical field of elevated bridge pier detection. The device for detecting elevated bridge piers, through the provision of a detection component, can drive a profiling mechanism locking frame to operate through the operation of a corresponding transmission component during the operation of the device. Simultaneously, the first and second profiling arms on the side of the profiling mechanism locking frame are extended through corresponding first, second, and third clamping cylinders, respectively, to clamp the pier. The clamped first and second profiling arms are moved through the coordination of a positioning electromagnet, a winch, a steel wire rope with a cable, and a lifting electromagnet, thereby performing detection operations through a surface detection component. This solves the problem of difficult and ineffective detection of elevated bridges or piers of elevated bridges hidden underwater.

The corresponding first contouring arm 16 and the second contouring arm 17 are rotatably connected with a contouring arm locking pin 19. The ends of the first tightening cylinder 18-1, the second tightening cylinder 18-2 and the third tightening cylinder 18-3 are provided with a tightening cylinder connecting pin 20, and are connected to the corresponding first contouring arm 16 and the second contouring arm 17 through the tightening cylinder connecting pin 20. A positioning cylinder 21 is fixedly installed on the outer side of the first contouring arm 16, and a clamping roller 22 and a guide shaft 23 are provided at the end of the positioning cylinder 21. The detection component also includes a distance sensor 24 and a surface detection component 25. The distance sensor 24 and the surface detection component 25 are fixedly mounted on the inner sides of the first contouring arm 16 and the second contouring arm 17 respectively;

[0029] In the embodiment of the present invention, a positioning electromagnet 12 is fixedly installed on the side of the profiling mechanism locking frame 11, and a winch 13, a steel wire rope with a cable 14 and a lifting electromagnet 15 are provided on the outer bottom of the profiling mechanism locking frame 11. The profiling mechanism locking frames 11 on both sides are symmetrical with each other and kept flush. The transmission assembly includes a second expansion cylinder 6, and the end of the rotating arm 102 is provided with an extension cylinder arm connecting pin 8, and is connected to the first extension cylinder arm 5 and the second expansion cylinder 6 through the cooperation and rotation of the extension cylinder arm connecting pin 8. Both ends are rotatably connected with the second cylinder connecting pin 7, and are respectively connected to the rotating arm 102 and the first extending cylinder arm 5 through the second cylinder connecting pin 7. The ends of the first extending cylinder arm 5 are respectively provided with the second extending cylinder 9 and the third expansion cylinder 10, and the end of the third expansion cylinder 10 is fixedly connected to the profiling mechanism locking frame 11. The transmission assembly also includes a first expansion cylinder 3 and a first cylinder connecting pin 4. There are two first expansion cylinders 3 and two first cylinder connecting pins 4, and they are respectively rotatably connected between the two rotating arms 102.

[0030] When in use, first operate the first expansion cylinder 3 to expand the corresponding rotating arm 102 through the first cylinder connecting pin 4 at the end until the rotating arm 102 and the transmission components on both sides and the profiling mechanism locking frame 11 are kept flush, as shown in FIG. Figure 1-2 Then, through the operation of the second expansion cylinder 6 on both sides, the corresponding first extended cylinder arm 5 is extended through the cylinder arm connecting pin 8 perpendicular to the bridge deck, as shown Figure 4 Then, by detecting the first holding cylinder 18-1, the second holding cylinder 18-2 and the third holding cylinder 18-3 in sequence, the corresponding first contouring arm 16 and the second contouring arm 17 are sequentially expanded, as shown. Figure 5-6 As shown, until the corresponding first contouring arm 16 and the second contouring arm 17 are kept flush, and then the third expansion cylinder 10 on both sides is operated to drive the second extension cylinder 9 to rotate and drive the corresponding contouring mechanism locking frame 11 to operate until the contouring mechanism clamping roller 22 is perpendicular to the bridge surface.

Figure 8 As shown; then the positioning cylinder 21 is actuated, and through the cooperation with the distance sensor 24, the clamping roller 22 is squeezed against the pier surface, and then the profiling mechanism locking frame 11 on the other side approaches the first profiling arm 16 and the second profiling arm 17 in the same way, and the first profiling arm 16 is adsorbed on the profiling mechanism locking frame 11 through the cooperation of the positioning electromagnet 12 and the lifting electromagnet 15, as shown Figure 9 As shown, the positioning electromagnet 12 and the winch 13 are then activated to slowly lower the profiling mechanism formed by the first profiling arm 16 and the second profiling arm 17, and the surface detection component 25 is activated to realize the detection operation of the bridge pier.

[0031] Example 2:

[0032] Based on Example 1, the difference from Example 1 is that locking wheels are provided at the bottom of the rotating arms 102 on both sides, and the locking wheels are used to provide support when the rotating arms 102 are extended or retracted. When the rotating arms 102 are extended or retracted, the locking wheels are locked to avoid position displacement.
