[0027] In this example, there are two stabilizing mechanisms 2, which are symmetrically distributed front and back with the central axis of the bracket 1 as the symmetry line. The top wall and the bottom wall of the inner cavity of the fixing groove 202 are provided with positioning grooves located on the bracket 1, and the left and right ends of the movable column are provided with square grooves 206. The first connecting plates 203 on the front and rear sides are pulled outward to make the two second connecting plates 204 begin to flip, so that the second universal wheels 205 on the front and rear sides can fit with the road surface, and the front and rear side latch members 201 are respectively positioned by the clearance between the front and rear side square rods and the square grooves 206 to prevent the movable column from moving, so as to achieve the purpose of positioning the second connecting plate 204.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] The working principle of the above embodiment is:

[0035] (1) When the tunnel emergency repair intelligent transport and management vehicle is needed, the tunnel emergency repair intelligent transport and management vehicle is moved by the first universal wheel 7 to move the tunnel emergency repair intelligent transport and management vehicle to the bottom of the pipeline to be transported. At this time, the electric push rod 3 is started to move the support platform 5 vertically upward so that the pipeline to be cut contacts the support platform 5. When the cutting is completed, the left and right rockers are rotated to make the left and right movable rods 403 start to rotate and drive the left and right positioning plates 406 to position the pipeline. At this time, the support platform 5 is moved downward to lower the center of gravity of the pipeline and drive the tunnel emergency repair intelligent transport and management vehicle to move horizontally to the left.

[0036] (2) In order to prevent the tunnel emergency repair intelligent transport and management vehicle from transporting pipelines in an unstable manner due to bumps in the road surface, the first connecting plates 203 on the front and rear sides are pulled outward to allow the two second connecting plates 204 to flip over, so that the second universal wheels 205 on the front and rear sides can fit with the road surface, and the front and rear side latch members 201 are respectively positioned by the clearance between the front and rear side square rods and the square grooves 206 to prevent the movable columns from moving, thereby achieving the purpose of positioning the second connecting plates 204. The second universal wheels 205 on the front and rear sides can improve the stability of the tunnel emergency repair intelligent transport and management vehicle and avoid the problem of unstable center of gravity due to the excessive length of the pipeline.
