Detailed ways

As shown in Figures 1 to 4, in this embodiment, a total station placement device in a tunnel is proposed, which includes a No. 1 mounting plate 3, a No. 2 mounting plate 4 and a U-shaped frame 5. The U-shaped frame 5 The upper end side wall is fixedly connected to the No. 1 mounting plate 3, the lower end side wall of the U-shaped frame 5 is fixedly connected to the No. 2 mounting plate 4, and the U-shaped frame 5 always remains vertical in the vertical direction. The two mounting plates are provided with It is a connecting component for fixing and moving in the length direction of the tunnel, and a placement component for installing a total station is provided on the inside of the U-shaped frame 5 .

The connection component includes a sliding bolt 6 and a nut 7. The tail of the sliding bolt 6 penetrates the mounting plate. The sliding bolt 6 and the mounting plate are fixed by the nut 7.

The placing assembly includes a placing platform 8. The surface of the placing platform 8 is provided with mounting holes 9. Connecting plates 10 are vertically installed on both sides of the upper surface of the placing platform 8. There is an adjusting device between the connecting plate 10 and the U-shaped frame 5. There is an angle adjustment mechanism for adjusting the angle between the mounting platform 8 and a distance adjustment mechanism for adjusting the distance between the mounting plate 3 and the connecting plate 10. The shape of the connecting plate 10 is L-shaped.

The distance adjustment mechanism includes a No. 1 oblong hole 11 on both sides of the U-shaped frame 5 and a No. 2 oblong hole 12 on the connecting plate 10. The No. 1 oblong hole 11 and the No. 2 oblong hole 12 are movable and fixed inside. Bolt 14.

The angle adjustment mechanism includes arc-shaped oblong holes 13 opened on the two connecting plates 10. Fixing bolts 14 are movably inserted inside the No. 1 oblong hole 11 and the arc-shaped oblong hole 13.

The working principle of a total station placement device in a tunnel proposed in this embodiment is as follows:

When this device is in use, it is necessary to open a strip chute 2 on the tunnel segment 1. When working, first snap the sliding bolt 6 inside the chute 2 of the segment 1, and then install the No. 1 installation plate 3 and the No. 2 The mounting plate 4 is installed on the corresponding sliding bolt 6, and then the nut 7 is turned on the bolt to fix the two mounting plates. After the mounting plate is fixed, install the total station in the mounting hole 9 of the placing table 8, that is The installation of the total station can be completed. When the total station needs to be transferred, only the nut 7 needs to be loosened. At this time, the sliding bolt 6 can move inside the chute 2 of the segment 1, thereby achieving the purpose of transferring the instrument.

If you need to adjust the height and angle of the total station during measurement, you can loosen the fixing bolts 14 that fix the No. 1 oblong hole 11 and the No. 2 oblong hole 12, the No. 1 oblong hole 11 and the arc-shaped oblong hole 13, and then make the first The fixing bolts 14 of the No. 1 oblong hole 11 and the No. 2 oblong hole 12, the No. 1 oblong hole 11 and the arc-shaped oblong hole 13 move and slide along the length direction of the No. 1 oblong hole 11. At this time, the entire placement platform 8 will also follow up and down. Move to achieve the effect of adjusting the vertical height of the total station; when the fixing bolt 14 of the No. 1 oblong hole 11 and the arc-shaped oblong hole 13 slides along the circumferential direction of the arc-shaped oblong hole 13, cooperate with the No. 1 oblong hole The angle of the total station can be adjusted by fixing the fixing bolts 14 in hole 11 and the No. 2 oblong hole 12. After the adjustment, only two sets of fixing bolts 14 need to be tightened to complete the fixation.
