[0024] The calibration mechanism includes a connecting plate 7, which is fixedly connected to the bottom of the crane body 1, and the side culvert body 2 is movably connected to the bottom of the connecting plate 7. The top of the connecting plate 7 is fixedly connected with a sensor 6, and the side of the connecting plate 7 is fixedly connected with a laser pen 8. The crane body 1 is slidably connected with a support plate 5 on the side close to the laser pen 8, and the support plate 5 is fixedly connected with the sensor 6. The bottom of the crane body 1 is fixedly connected with a fixing rod 3, and the bottom of the fixing rod 3 is slidably connected with a guide rod 9. The guide rod 9 is slidably connected with a U-shaped frame 10 on the side close to the side culvert body 2, and two bolts 13 are threadedly connected to the U-shaped frame 10, and the two bolts 13 are symmetrically distributed, and the bolts 13 are against the inner wall of the side culvert body 2.

[0025] An L-shaped groove 101 is opened on the crane body 1, and two L-shaped rods 4 are slidably connected inside the L-shaped groove 101. The two L-shaped rods 4 are symmetrically distributed. The L-shaped rod 4 is fixedly connected to the top of the support plate 5. One end of the L-shaped rod 4 is fixedly connected to a magnet plate 401. The magnet plate 401 is abutted against the crane body 1 to achieve sliding and limiting of the support plate 5 on the crane body 1.

[0026] A measuring line 102 is provided on the side of the crane body 1 , and the measuring line 102 and the magnet plate 401 are both on the same side of the crane body 1 , so that the support plate 5 is aligned with the side of the middle box culvert at the bottom, which facilitates the installation of the side box culvert body 2 .

[0027] A cone block 501 is fixedly connected to the support plate 5 at one side close to the laser pen 8 , so as to facilitate the detection of the offset direction between the connecting plate 7 and the side box culvert body 2 .

[0028] A mounting groove 301 is provided on the fixed rod 3, and a limiting block 12 is slidably connected inside the mounting groove 301. The limiting block 12 is fixedly connected to the top of the guide rod 9. The cross-sectional shape of the mounting groove 301 is a trapezoid, and the cross-sectional shape of the limiting block 12 is also a trapezoid corresponding thereto, thereby limiting the guide rod 9.

[0029] The guide rod 9 is provided with a slide groove 901 on one side close to the U-shaped frame 10, and a slider 11 is slidably connected to the slide groove 901. The slider 11 is fixedly connected to the U-shaped frame 10. The cross-sectional shape of the slide groove 901 is trapezoidal, and the cross-sectional shape of the slider 11 is also trapezoidal, thereby limiting the U-shaped frame 10.

[0030] Working principle: When the user uses it, when the side box culvert body 2 needs to be spliced ​​inside the tunnel, first push the L-shaped rod 4, the magnet plate 401 and the support plate 5 to align one end of the L-shaped rod 4 with the box culvert installed at the bottom, and then start the crane body 1, the sensor 6 and the laser pen 8. The crane body 1 drives the side box culvert body 2, the connecting plate 7, the laser pen 8 and the U-shaped frame 10 to move. The side box culvert body 2 moves up and down to drive the U-shaped frame 10 and the slider 11 to move up and down inside the guide rod 9. The side box culvert body 2 moves left and right to drive the U-shaped frame 10, the guide rod 9 and the limit block 12 to slide left and right inside the installation groove 301. As the sensor 6 works, It can be detected that the sensor 6 and the connecting plate 7 are at the same horizontal position. Since the laser on the laser pen 8 is mapped on the support plate 5, the offset direction of the connecting plate 7 and the side box culvert body 2 can be observed according to whether the laser point is on the left or right side of the cone block 501. One of the bolts 13 on the U-shaped frame 10 can be rotated according to the offset direction of the side box culvert body 2, so that the bolt 13 pushes the side box culvert body 2, the connecting plate 7 and the laser pen 8 to move, so that the laser emitted by the laser pen 8 coincides with the cone block 501, thereby realizing the calibration of the side box culvert body 2. Finally, the crane body 1 is started to make the side box culvert body 2 descend to coincide with the ground culvert, so as to facilitate the assembly of the side box culvert body 2.

[0031] This device is provided with an L-shaped rod 4, a support plate 5, a sensor 6, a connecting plate 7, a laser pen 8, a U-shaped frame 10 and a limit block 12. When used by a user, this device can ensure that the side box culvert body 2 can be calibrated by rotating the limit block 12 before falling. The mechanical calibration is more accurate and can be adjusted by one person, saving labor. The device has a simple structure and is convenient for assembling the side box culvert body 2.
