[0022] In this embodiment: By setting the second servo motor 901, the driving gear 902 and the driven gear 903, the rotation of the rotating shaft 6 can be facilitated.

[0023] As a technical optimization solution of the utility model, the clamping assembly 10 includes a concave frame 101. The connection part between the outer surface of the concave frame 101 and the rectangular frame 1 is fixedly connected. A stud 102 is threadedly connected to the left side of the concave frame 101.

[0030] In this embodiment: By setting the handle, the device can be conveniently moved. By setting the rubber plate, the connection part between the rectangular frame 1 and the bridge can be conveniently protected and supported.

[0031] As a technical optimization solution of the utility model, a limit bolt 14 is threadedly connected to the bottom of the positioning frame 7. A pin hole 15 is formed in the bottom of the support plate 8. The top of the limit bolt 14 penetrates through the positioning frame 7 and extends into the inner cavity of the pin hole 15.

[0032] In this embodiment: By setting the limit bolt 14 and the pin hole 15, the connection part between the support plate 8 and the positioning frame 7 can be limited.

[0033] Working principle: When it is necessary to survey the bottom of a bridge, the staff move the support plate 8 so that the support plate 8 slides into the inner cavity of the positioning frame 7. Then, the staff rotate the limit bolt 14 so that the limit bolt 14 inserts into the inner cavity of the pin hole 15, thereby installing the connection between the support plate 8 and the rotating shaft 6. Next, the staff use screws to cooperate with the installation holes to fixedly install the surveying equipment on the top of the mounting plate 13. Then, the staff move the handle, so that the handle drives the device to move to the outside of the bridge guardrail. At the same time, the bridge guardrail is located in the inner cavity of the concave frame 101. When the device moves to the designated survey position, the staff rotate the stud 102, so that the stud 102 drives the clamping plate 103 to threadedly rotate and move on the inner surface of the concave frame 101 to closely fit the connection with the bridge guardrail. At the same time, the connection between the bridge guardrail and the concave frame 101 is closely fitted, thereby clamping and installing the connection between the device and the bridge guardrail. Next, the staff connect the plug of the first servo motor 2 and start the external controller of the first servo motor 2, so that the output end of the first servo motor 2 drives the screw rod 3 to threadedly rotate on the inner surface of the movable plate 4. At the same time, the movable plate 4 drives the positioning box 5 to move downward, so that the positioning box 5 drives the rotating shaft 6, the positioning frame 7, the support plate 8 and the surveying equipment to move to an appropriate survey depth. Then, the staff connect the plug of the second servo motor 901 and start the external controller of the second servo motor 901, so that the output end of the second servo motor 901 drives the driving gear 902 to rotate. The driving gear 902 drives the driven gear 903 to rotate. The driven gear 903 drives the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the positioning frame 7 to rotate. The positioning frame 7 drives the support plate 8 to rotate, so that the support plate 8 drives the mounting plate 13 and the surveying equipment to rotate and move to the bottom of the bridge, thereby facilitating the surveying equipment to survey it. The device is simple to operate and convenient for surveying use, so it can meet the usage requirements of customers. At the same time, it effectively reduces the labor intensity and surveying cost of the staff.
