The rotating frame 6 is provided with hydraulic rods 3 22 on the front and rear sides respectively. The left and right sides of the hydraulic rods 3 22 are fixedly connected to the fixed frames 21 on the corresponding sides respectively. The left side of the output end of the hydraulic rods 3 22 is hinged to the fixed plate 8.

[0030] like Figures 1 to 4 As shown, a fixed frame 21 is provided for fixing and supporting a hydraulic rod three 22. The hydraulic rod three 22 can be used to drive the lifting frame 7 to move up and down, so as to facilitate adjusting the height of the construction platform 11.

[0031] The adjusting assembly 9 includes a turntable 23 and two hydraulic rods four 24. The turntable 23 is rotatably connected to the fixed plate 8.

The two hydraulic rods four 24 are opposite to each other and are hinged to the fixed plate 8 at their back ends. The output end of the hydraulic rod four 24 is hinged to the fixing pin 25 on its corresponding side.

[0032] like Figure 1 and Figure 5 As shown, the turntable 23, the hydraulic rod four 24 and the fixed pin 25 can be set up so that the two hydraulic rods four 24 can be used to start synchronously to drive the turntable 23 to rotate through the fixed pin 25, and then the turntable 23 drives the connecting plate 10 to rotate, which can drive the construction platform 11 to rotate, thereby expanding the detection range.

[0037] When the utility model is in use, the trolley 1 is moved to the edge of the bridge, and then the driving motor 12 is started. The driving motor 12 drives the slave gear 14 to rotate on the rotating base 15 through the main gear 13. Then, when the bracket 4 is in a vertical state with the bridge edge, the hydraulic rod 2 19 is started. The hydraulic rod 2 19 drives the rotating frame 6 to rotate around the rotating shaft 5 through the swing frame 20. The lifting frame 7 rotates with the rotating frame 6. When the rotating frame 6 is vertical to the ground, the hydraulic rod 2 19 is closed. Then the hydraulic rod 5 26 is started. The hydraulic rod 5 26 drives the construction platform 11 to rotate. When the top block 27 contacts the connecting plate 10, the hydraulic rod 5 26 is closed. The construction platform 11 is in a horizontal state, and the inspection personnel can enter the construction platform 11. Then the hydraulic rod 3 22 is started. After the hydraulic rod 3 22 drives the lifting frame 7 to descend to a suitable position, the hydraulic rod 3 22 is closed to complete the vertical descent of the inspection personnel.

[0038] Then, the hydraulic rod 17 is started, and the hydraulic rod 2 19 and the hydraulic rod 3 22 move in coordination. The hydraulic rod 17 drives the support rod to move upward. The hydraulic rod 2 19 ensures that when the left side of the bracket 4 is swung up, the lifting frame 7 is always in a vertical state on the ground. At the same time, the hydraulic rod 3 22 can ensure that the construction platform 11 is at the target height and will not be lifted due to the swing of the bracket 4. When the distance between the construction platform 11 and the bridge body reaches the required distance of the inspector, the hydraulic rod 17, the hydraulic rod 2 19 and the hydraulic rod 3 22 are closed, and the inspection can be carried out;

[0039] When it is necessary to inspect other positions such as the bottom of the bridge, the hydraulic rod three 22 is started and the construction platform 11 continues to descend to a suitable height. At the same time, the two hydraulic rods four 24 are started. The hydraulic rod four 24 drives the turntable 23 to rotate through the fixed pin 25, and then drives the construction platform 11 to rotate to a suitable position. After that, the hydraulic rod four 24 is closed to continue the inspection.

[0040] In the present invention, all hydraulic rods have self-locking capability and are prior art, so they will not be described in detail here.
