By setting the adjustment structure 8, it is convenient to adjust the irradiation angle of the laser irradiation lamp 7, thereby improving the monitoring range of the railway frame box bridge, and then the deformation and potential problems of the bridge structure can be fully and accurately monitored. A limiting structure 9 is provided on the surface of the base 4. By setting the limiting structure 9, it is convenient to limit the position of the base 4, and then limit the position of the laser irradiation lamp 7, so as to avoid the situation that the position of the laser irradiation lamp is offset due to accidental contact when monitoring the railway frame box bridge, thereby improving the accuracy of the monitoring results of the railway frame box bridge.

[0031] The specific settings and functions of the adjustment structure 8 and the limiting structure 9 are described in detail below.

[0032] Reference Figure 2 and Figure 3 and Figure 4As shown, in this embodiment: the adjustment structure 8 includes a fixed frame 801, the inner wall of the fixed frame 801 is rotatably connected with a driving block 802, the driving block 802 is fixedly connected to the surface of the laser irradiation lamp 7, the surface of the fixed frame 801 is fixedly connected with a frame body 803, the surface of the frame body 803 is threaded with a threaded rod 804, one end of the threaded rod 804 is rotatably connected with a serrated plate 805, the surface of the driving block 802 is fixedly connected with an arc-shaped rack 806, the serrated plate 805 is meshed with the arc-shaped rack 806, the inner wall of the fixed frame 801 is fixedly connected with a fixed plate 807, and the fixed plate 807 is slidably connected to the surface of the serrated plate 805. The sawtooth plate 805 has limit slots 808 on both sides, and the inner wall of the limit slot 808 is slidably connected to the limit rod 809, and the limit rod 809 is fixedly connected to the surface of the frame body 803. When the sawtooth plate 805 moves, the limit rod 809 slides along the inner wall of the limit slot 808, and the limit rod 809 limits the movement distance of the sawtooth plate 805, thereby preventing the sawtooth plate 805 from disengaging from the arc-shaped rack 806. A groove 810 is provided on the side of the fixed plate 807 close to the sawtooth plate 805, and the inner wall of the groove 810 is rotatably connected to a plurality of rotating shafts 811. When the sawtooth plate 805 moves, it slides along the surface of the rotating shaft 811, and the rotating shaft 811 rotates in the groove 810, and the rotating shaft 811 reduces the friction force when the sawtooth plate 805 slides along the surface of the fixed plate 807. One end of the threaded rod 804 away from the serrated plate 805 is fixedly connected to a turntable 812 , the cross section of which is in the shape of a cross. The rotation of the turntable 812 drives the threaded rod 804 to rotate, and the turntable 812 facilitates the rotation of the threaded rod 804 .

[0033] Reference Figure 5 As shown, specifically, the limiting structure 9 includes two brackets 91, both of which are fixedly connected to the surface of the base 4. The surface of the bracket 91 is threaded with a driving rod 92, and the driving rod 92 is rotatably connected to a rectangular plate 93 on the side close to the bottom plate 1. The surface of the bracket 91 is slidably penetrated by a round rod 94, and the round rod 94 is fixedly connected to the surface of the rectangular plate 93. The movement of the rectangular plate 93 will drive the round rod 94 to slide in the bracket 91, and the round rod 94 can limit the moving path of the rectangular plate 93, thereby preventing the rectangular plate 93 from rotating when moving. A plurality of limiting blocks 95 are fixedly connected to the side of the rectangular plate 93 close to the bottom plate 1, and the plurality of limiting blocks 95 are all made of rubber. The limiting blocks 95 can increase the friction between the rectangular plate 93 and the ground, thereby further improving the effect of the rectangular plate 93 limiting the base 4.

[0034] Working principle: when the irradiation angle of the laser irradiation lamp 7 needs to be adjusted, first turn the turntable 812. The rotation of the turntable 812 will drive the threaded rod 804 to rotate. The threaded rod 804 will move in the frame body 803 with the help of the thread. The movement of the threaded rod 804 will drive the sawtooth plate 805 to move. The sawtooth plate 805 will slide along the surface of the rotating shaft 811. The rotating shaft 811 will rotate in the groove 810. The rotating shaft 811 can reduce the friction force when the sawtooth plate 805 slides along the surface of the fixed plate 807. The fixed plate 807 can avoid the sawtooth The plate 805 rotates when it moves. The serrated plate 805 causes the limiting rod 809 to slide along the inner wall of the limiting groove 808 when it moves. The limiting rod 809 limits the moving distance of the serrated plate 805, thereby preventing the serrated plate 805 from being disengaged from the arc-shaped rack 806. When it moves, the serrated plate 805 drives the arc-shaped rack 806 to rotate with the help of its teeth. The rotation of the arc-shaped rack 806 drives the driving block 802 to rotate. The rotation of the driving block 802 drives the laser irradiation lamp 7 to rotate, thereby adjusting the irradiation angle of the laser irradiation lamp 7.

[0035] When it is necessary to monitor the railway frame box bridge, first move the base 4 to a suitable position, and then rotate the drive rod 92. The rotation of the drive rod 92 will move in the bracket 91 with the help of the thread. The movement of the drive rod 92 will drive the rectangular rod to move in the approaching direction. The movement of the rectangular plate 93 will drive the round rod 94 to slide in the bracket 91. The round rod 94 limits the moving path of the rectangular plate 93, thereby preventing the rectangular plate 93 from rotating when moving. When the rectangular plate 93 moves to a suitable position, it will drive the limit block 95 to fit closely to the ground. The limit block 95 increases the friction between the rectangular plate 93 and the ground, thereby further improving the effect of the rectangular plate 93 limiting the base 4.
