Background technology
Single plane cable stayed bridge generally is in girder cross section centre position suspension cable to be set, and along bridge many group suspension cables is set vertically, connects girder and king-tower.As the suspension cable of main load-carrying member, weight and the various load action of girder passed to king-tower, be one of main member of cable stayed bridge.Single plane cable stayed bridge has obtained increasing application owing to handsome in appearance in bridge engineering, so the suspension cable maintenance also is the constant demand that exists.The lot of domestic and international cable stayed bridge has been implemented cable replacement engineering, the suspension cable of the cable stayed bridge that also has is because of anchor head corrosion fracture, cause disaster to occur, also explicitly call for the maintenance maintenance requirement during considering to run in the CONSTRUCTION OF CABLE-STAYED BRIDGE design among " road oblique roller bridge design details " (JTG/T D65-01-2007), as seen to the importance of the maintenance repair of suspension cable.A lot of cable stayed bridges are considered for view in addition, are provided with landscape lighting luminaire at suspension cable, need to consider the examination and repair system design equally when designing to the maintenance of these lightings.
In the Design of Cable-Stayed Bridge in past, once inconsiderate to the maintenance inspection requirements, lack checkout facility, the bridge that has even have to adopt fire balloon inspection.Now inspection method commonly used is to adopt the crane inspection platform inspection of slinging, and the suspension cable that has is higher, and is high to the requirement of crane, almost takies whole track scope, very large to the normal influence on system operation of road.The lifting operation platform is easily run into suspension cable, damage the outer PE sheath of suspension cable, and operating efficiency is low, and inspection is once wasted time and energy expensive.
Summary of the invention
For the deficiency that existing cable stayed bridge maintenance field exists, the utility model purpose provides a kind of examination and repair system of single plane cable stayed bridge suspension cable.
For realizing the purpose of this utility model, concrete technical scheme is:
A kind of examination and repair system of single plane cable stayed bridge suspension cable, this examination and repair system comprises climbing device, the first power set, safety rope, the job platform that can settle the maintainer and falling proof device, be provided with the roller of draw-in groove below the climbing device, climbing device contacts with the suspension cable of single plane cable stayed bridge by the roller that draw-in groove is arranged, described the first power set are installed in the climbing device, described climbing device is connected by rope with described job platform, described falling proof device is positioned at the bridge tower top of single plane cable stayed bridge, is connected with maintainer in the job platform by safety rope.
Wherein, described the number of the roller of draw-in groove is arranged is even number, contacts with the uppermost a pair of suspension cable of single plane cable stayed bridge, and the spacing between the roller is adjustable.
Wherein, described have the roller of draw-in groove to contact with the uppermost a pair of suspension cable of single plane cable stayed bridge, its mode is the draw-in groove that suspension cable is positioned at roller, and this has the roller of draw-in groove to use with the same material of the sheath of the suspension cable of single plane cable stayed bridge to make, for example the PE material.
Wherein, lifting rope is installed in described the first power set, the lifting rope of pulling out is positioned at the top of the uppermost a pair of suspension cable of single plane cable stayed bridge, and the bridge tower top of lifting rope one end and single plane cable stayed bridge is fixed, and the beam of the other end and single plane cable stayed bridge is fixed.
Wherein, vertical the second mobile power set of driving job platform are installed on the described job platform.
A kind of method of using described examination and repair system maintenance single plane cable stayed bridge, comprising: the maintainer is arranged in described job platform, by the first power set of controlling examination and repair system examination and repair system is moved along the suspension cable direction; By the second power set that the control job platform is installed, make job platform vertically mobile up and down, carry out the maintenance to the single plane cable stayed bridge all sites.
Wherein, described examination and repair system moves along the suspension cable direction, is by the driving of the first power set of examination and repair system, moves around in the suspension cable direction along lifting rope.
Wherein, described job platform is vertically mobile up and down, is along the rope that connects crawl device, and the driving of the second power set by job platform is vertically mobile up and down.
Wherein, described falling proof device is connected with the maintainer who is arranged in described job platform by safety rope.
The beneficial effects of the utility model are:
The climbing device of examination and repair system of the present utility model can be creeped along suspension cable, the job platform of hanging on the climbing device can be vertically mobile up and down, the two combination, thereby realized that job platform can arrive each position of whole suspension cables, thereby realized the maintenance function to whole suspension cables and upper attached light fixture.The automatic adjustable interval of the roller of the climbing device of this system is applicable to the suspension cable of unequal-interval.Cat head arranges anti-falling mechanism, guarantees the safety of maintainer when work.
Single rope face suspension cable generally is arranged in the central partition of bridge, and examination and repair system of the present utility model does not need by main equipments such as cranes, therefore, can not affect normal traffic.Roller draw-in groove and suspension cable adopt the material of same intensity and rigidity outward, can be to the suspension cable injury.
Examination and repair system operating efficiency of the present utility model is high.The repair apparatus cost is low, and maintenance cost is little.
