Wherein, described cat ladder is that aluminium alloys is made.
Wherein, described inserted link can around 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 also comprises one end and is fixed on safety rope on the falling proof device of Sarasota top, and the other end of safety rope is connected with personnel in job platform.
Wherein, described job platform is also provided with the control system driving the vertical movement of job platform.
A kind of method using examination and repair system proposed by the invention to overhaul solid Sarasota, comprise step: first job platform is placed in bridge floor place, personnel carry lifting rope and safety rope, Sarasota top is climbed up from cat ladder, lifting rope one end is fixed on suspension hook, safety rope one end is fixed on the falling proof device of tower top, rotate the inserted link of suspension centre, inserted link hook is made to be suspended from outside tower top edge, locking inserted link, put down lifting rope and safety rope, again lifting rope is arranged on job platform, personnel enter job platform, with it safety rope is tied up to, operation control system, job platform is risen to the maintenance position of Sarasota, Sarasota is overhauled.
After maintenance terminates, fall job platform to bridge floor, take off lifting rope and safety rope, the inserted link of lifting-point device is rotated in tower top edge, fixing.
Personnel climb down along cat ladder, and job platform is pushed into indoor, and maintenance terminates.
Beneficial effect of the present invention is:
1) the lifting-point device volume of tower top is little, little on the layout impact of other ancillary facility of tower top, and it is few to maintain workload.
2) the tower top suspension centre structure not used time, can go in tower top and cover, be beneficial to maintenance, and little to bridge landscape impact.
3) the used time is not placed on storehouse for job platform, lifting rope, and avoid and be exposed to outdoor, application life increases greatly.
4) during upkeep operation, because j ob impact scope is little, little on the impact of driving.
