So that staff overhauls on workbench to beam body, or on the service aisle of side the beam body edge of a wing is checked and
Safeguard；
(2) after overhauling, when first group of U-shaped frame needs to pass through bridge pier, control tensioning hydro-cylinder thereon to unclamp, make both sides
Horizontal connector disengages；
(3) overturning oil cylinder controlled level connector rotating opening is utilized, walking mechanism movement is then controlled, makes first group of U
Type frame passes through bridge pier；
(4) circulation step (2), (3), the U-shaped frame of all groups is sequentially controlled to pass through bridge pier.
Further, during walking mechanism moves along bridge, displacement transducer detects walking and takes turns to bridge in real time
The distance of beam body, and electric control gear is fed back to, elongated or shortened in real time by electric control gear control compressed oil cylinder, it is ensured that to bridge
Enclasping force.
Compared with prior art, the invention has the advantages that：
(1) present invention is reasonable in design, compact-sized, security performance is high, operate comfortable labor-saving, maintenance is convenient, comprehensively.
(2) present invention is by setting the U-shaped frame that can be opened and closed, and there is provided workbench and side work are logical
Road, not only convenient after maintenance bridge pier can be bypassed, realize the continuous Inspection of multispan, and by vehicle with walking machine on U-shaped frame
Structure, bridge can be held tightly and be moved along it, without pre-track, the cost of construction costs is greatly reduced.
(3) present invention can provide bridge enough thrusts, it is ensured that inspection by hydraulic pressure, automatically controlled synergy
Look into the walking safety of car.
