Abstract
The utility model discloses a stay cable tower end exterior tower type telescopic construction platform, which comprises a tower frame of a truss structure which is arranged on a bridge tower column, a climbing-frame foot platform with a lifting frame is arranged on the tower frame, and a telescopic movable platform is arranged on the climbing-frame foot platform. The stay cable tower end exterior tower type telescopic construction platform has convenient installation and use and very high safety performance, the design adopts the telescopic foot platform, the adaptability is strong, and good operability is available. The design and use of the stay cable tower exterior construction platform greatly enrich the construction technique of a stay cable, and the device has good effect in bridge construction, which is convenient for construction and guarantees the construction progress.
Description
Technical field
The utility model belongs to the construction frock, is specifically related to a kind of tower scalable operation platform that is used for the outside construction of oblique tensile tower end.
Background technology
Suspension cable is torn constructions such as worker's rigging and suspension cable PE protection open in the lifting of tower end, traction, angle adjustment, peace; be to carry out drag-line around tower full hall pin hand platform or cage to hang construction traditionally; workload is big and not easy to operate; strong to the tower crane dependence; very easily be subjected to wind effect; to be difficult to guarantee constructor's safety, and be unfavorable for the protection of suspension cable PE.Long and heavy for suspension cable, long, the big bridge of traction anchored force of hauling distance when hanging, conventional single soft traction or draw technology firmly and can not satisfy the construction needs.
Summary of the invention
The purpose of this utility model is to provide a kind of oblique tensile tower end outside tower scalable operation platform, to address the above problem.
The technical solution of the utility model is: the outside tower scalable operation platform of oblique tensile tower end, it comprises the pylon that is located at the trussed construction on the bridge king-post, establish the climbing frame job platform that has jacking frame on the pylon, the climbing frame job platform is provided with telescopic movable platform.
Described telescopic movable platform comprises platform floor, establishes guardrail on the platform floor, the guide beam that platform floor connects, and guide beam is located on the roller.
Roller is located on the climbing frame job platform.
The utility model install and easy to use, have a very high security performance; Scalable job platform is adopted in design, and compliance is strong and have a good operability.Oblique tensile tower is the design and the use of operation platform outward, has greatly enriched the construction technology of suspension cable.This device has good effect in bridge construction, made things convenient for construction, has guaranteed construction speed.Be applicable to large and medium-sized cable stayed bridge oblique tensile tower end construction under this is practical, tear the operating platform of operations such as worker's rigging and suspension cable PE protection as suspension cable in the lifting of tower end, traction, angle adjustment, peace open.
Description of drawings
The outside tower scalable operation platform schematic diagram of Fig. 1 oblique tensile tower end.
Fig. 2 climbing frame job platform schematic diagram.
The telescopic movable platform structural representation of Fig. 3.
The specific embodiment
As shown in Figure 1, the trussed construction of pylon 1 is that the standard knot spelling by tower crane forms, and pylon 1 vertically is arranged in upper king-post strut staying cable anchorage zone 3, is supported on the steel corbel 2 that is fixed on the tower limb, and arranges one attached wall stull 4 every 12m.Pylon also is the vertical passageway of going up lower platform.Establish the climbing frame job platform 5 that has jacking frame on the pylon 1, climbing frame job platform 5 is provided with telescopic movable platform 6.
As shown in Figure 2, the jacking frame 7 on the climbing frame job platform 5 adopts the jacking frame of tower crane, and platform (platform is by the rope side) is set in the above.Jacking frame 7 carries job platform and can move up and down along pylon, is fixed on the pylon behind the arrival construction location.
As shown in Figure 3, telescopic movable platform 6 comprises platform floor 10, establishes guardrail 11 on the platform floor 10, the guide beam 12 that platform floor 10 connects, and guide beam 12 is located on the roller 13.Roller 13 is located on the climbing frame job platform 5, is provided with in pairs up and down.Establish stationary positioned hole 16 on the guide beam 12.After telescopic movable platform 6 flexible the putting in place, can be telescopic movable platform 6 is fixing with climbing frame job platform 5 by locating hole 16 and bolt.Connect drive unit on the telescopic movable platform 6.Drive unit comprises be articulated and connected cramp bar 14 on platform floor of an end, and the other end of cramp bar 14 is connected manually or on the electric block 15, manually or electric block 15 be movably connected on the pylon 1.
For construction safety, jacking frame peripheral hardware falling proof device is guaranteed construction installation and personnel's safety.
For making things convenient for about the personnel, reduce personnel's walking intensity of climbing, access to elevators is set outside tower at a certain distance, access to elevators is communicated with pylon.When the staff by elevator on behind the access to elevators, by on the passage to pylon, hang up operation by carrying out suspension cable to job platform on the cat ladder in the pylon again.
