By the arrangement of the structure, the folding, aligning locking or unlocking of the bridge body can be conveniently realized, and the locking can be conveniently and smoothly realized even when the bridge body is vertically staggered.

The locking portion and the locked portion in this embodiment may be provided on a set of opposing chords of the bridge body, respectively. The chord member referred to herein may be the upper or lower chord of the bridge. Of course, in other embodiments, the locking portion and the locked portion may be provided at other suitable locations on the bridge body.

In one implementation of this embodiment:

the maximum height-direction spacing of the matching space defined by the lifting mechanism and the upper limiting piece is larger than the height-direction size of the locking pin.

In one implementation of this embodiment:

the lifting mechanism comprises a lifting rack, a lifting connecting piece and a lifting wheel;

the lower end of the lifting rack is rotatably connected to the bridge body; the lower end of the lifting connecting piece is hinged to the lifting rack, and the upper end of the lifting connecting piece is slidably matched with a vertical sliding rail arranged on the bridge body; the lifting wheel is connected to the upper end of the lifting connecting piece;

the lifting driver is in transmission connection with the lifting rack and can drive the lifting rack to rotate so as to drive the lifting wheels to vertically lift along with the upper end of the lifting connecting piece.

In one implementation of this embodiment:

the upper chord and the lower chord of the bridge body are both arranged into box girder structures and are provided with two chord side plates which are transversely spaced along the bridge; the lifting rack is rotatably connected between the two string side plates through a rack pin; the lower end of the lifting connecting piece is hinged to the upper part of the lifting rack through a hinge pin;

The relative locking structure of the bridge body in the scheme can be used for locking and connecting two bridge bodies.

When the locking device is used, if the two bridge bodies are just in a highly adaptive state, the two locking pins can be smoothly inserted into the matching space;

if one of the bridge bodies is relatively low in vertical direction due to the influence of self weight, wind load or other factors, the locking pin on the lower bridge body can still extend into the corresponding locking cavity because the maximum vertical dimension of the matching space is larger than the vertical dimension of the locking pin (of course, the locking pin on the other bridge body can be blocked by the upper edge of the corresponding locking cavity and cannot be inserted); at the moment, the locking pin on the lower bridge body can be inserted into the corresponding locking cavity, then the lifting mechanism arranged at the locking cavity exerts upward jacking force on the locking pin, the jacking force can drive the locking pin and the connecting end of the bridge body connected with the locking pin to integrally lift to a state of being in high adaptation with another bridge body, and the other group of locking pins can also be smoothly inserted into the corresponding locking cavities, so that the locking pins can be locked up and down respectively.

In the scheme, when one of the bridges is relatively low in vertical direction due to the influence of self weight, wind load or other factors, the locking pin on the lower bridge still can extend into the corresponding locking cavity due to the arrangement of the surplus gap (of course, the locking pin on the other bridge can be blocked by the corresponding upper limiting piece and cannot be inserted); at the moment, the locking pin on the lower bridge body can be inserted into the corresponding matching space, then the lifting mechanism arranged at the matching space exerts upward jacking force on the locking pin, the jacking force drives the locking pin and the connecting end of the bridge body connected with the locking pin to integrally lift to a state of being in high adaptation with the other bridge body, and the other group of locking pins can be smoothly inserted into the corresponding matching space, so that the locking pins can be locked up and down respectively.
