The two ends of the connecting beam mechanism 5 are respectively connected with the vertical frame mechanisms 1 at the two transverse sides so as to connect the two vertical frame mechanisms 1 into a whole. Due to the structural arrangement, the rigidity of the stand mechanism 1 is improved firstly, and the running stability of the whole inspection vehicle 100 is further improved; secondly, the synchronous walking of the vertical frame mechanisms 1 on the two sides is ensured, and the phenomena of blocking and the like are avoided; thirdly, the relative position of the stand mechanism 1 can be fixed, the checking platform mechanism 4 is prevented from shaking, and the safety of the operating personnel is ensured.
Preferably, in the longitudinal direction, two connection beam means 5 may be provided for more stable connection of the stand means 1. At the same time, the two connecting beam mechanisms 5 are longitudinally spaced apart to allow at least part of the inspection platform mechanism 4 to pass vertically therethrough. This arrangement enables the structure to be more compact, and ensures that the inspection platform mechanism 4 has a greater vertical movement distance.

A positioning assembly is provided between the connecting beam mechanism 5 and the inspection platform mechanism 4. Specifically, the positioning assembly has a first positioning block 51 and a second positioning block 43. Wherein, the first positioning block 51 is arranged at the longitudinal inner side of the connecting beam mechanism 5 in a protruding mode. And the second positioning block 43 is provided protrudingly on the longitudinal outside of the inspection stage mechanism 4.

And a second end of the lifting rope 61 is fixed to the winding shaft 41 after being pulled out by the lifter. During the lowering of the inspection platform mechanism 4, the lifting rope 61 is loosened. At this time, the second motor 42 may be activated to wind the released lifting rope 61 around the winding shaft 41, and conversely, the lifting rope 61 needs to be tightened by the lifter during the raising of the inspection platform mechanism 4. At this time, the second motor 42 may be activated to run in reverse and release the lifting cord 61 wound on the winding shaft 41. Also from this, above-mentioned setting has played the effect of accomodating to lifting rope 61, and then has played the effect of combing the arrangement to lifting rope 61, prevents that unexpected winding from influencing the normal elevating movement of inspection platform mechanism 4. In addition, since the second end of the lifting rope 61 is fixed to the winding shaft 41, the problem that the lifting rope 61 falls off from the hoist is also avoided.

The running gear 2 of the inspection vehicle 100 is hoisted on the track, and the running gear 2 drives the whole inspection vehicle 100 to run along the track under the driving of the first driving mechanism 3. At this time, the bottom wall of the bridge is inspected by a technician standing on the inspection platform mechanism 4, and the side wall of the bridge is inspected by standing on the platform plate 131.
The position of the inspection platform means 4 can be set by the second drive means 6 for better passage of the beam or for better inspection of the bottom wall. For example, the position of the inspection platform mechanism 4 at the height of the trabeculae is given in fig. 3, while the position of the inspection platform mechanism 4 at the height of the longerons is given in fig. 4. Therefore, the inspection vehicle 100 can conveniently inspect the bridge with the variable beam height. Meanwhile, the inspection vehicle 100 also has the advantages of large overall rigidity, stable operation, difficulty in jamming during walking and the like.
