Wherein, described climbing device also comprises climb-aiding device, and climb-aiding device is installed on the cat ladder.
Wherein, described cat ladder is that aluminium alloys is made.
Wherein, described inserted link can center on turning cylinder 180 ° of rotations in horizontal plane.
Wherein, described turning cylinder also comprises the parts that locking is rotated.
Wherein, described falling proof device comprises that also an end is fixed on the safety rope on the falling proof device of Sarasota top, and the other end of safety rope is connected with personnel in the job platform.
Wherein, the vertical mobile control system of driving job platform also is installed on the described job platform.
A kind of method of using examination and repair system described in the utility model to overhaul solid Sarasota, comprise step: during service work, first job platform is placed the bridge floor that is pushed under the bridge tower from indoor, personnel carry lifting rope and safety rope, climb up the Sarasota top from cat ladder, lifting rope one end is fixed on the suspension hook, anti-falling safe rope one end is fixed on the falling proof device of cat head, rotate the inserted link of suspension centre, the inserted link hook is suspended from outside the cat head edge, and the locking inserted link puts down lifting rope and safety rope, again lifting rope is installed on the job platform, personnel enter job platform, with it safety rope is tied up to, start control system, job platform is risen to the maintenance position of Sarasota, Sarasota is overhauled.
Described maintenance is fallen job platform to bridge floor after finishing, and takes off lifting rope and safety rope, and the cat head personnel pack up lifting rope, and the inserted link of lifting-point device is rotated in the cat head edge, and is fixing.
Personnel climb down along cat ladder, job platform are pushed into indoor, and maintenance finishes.
The beneficial effects of the utility model are:
1) the lifting-point device volume of cat head is little, and is little on the layout impact of other ancillary facility of cat head, and the maintenance workload is few.
2) cat head suspension centre structure time spent not can go in the cat head and covers, and is beneficial to maintenance, and is little to the bridge landscape impact.
3) job platform, lifting rope not the time spent be placed on storehouse, avoided being exposed to outdoor, greatly increase application life.
4) during upkeep operation, because the operation influence basin is little, little on the impact of driving.
