Technical field
What this utility model related to cable-stayed bridge cable system safeguards inspection platform used in construction and the maintenance of king-post lateral surface or decoration.
Background technology
In stayed bridge pylon cable work progress, generally adopting hydraulic climbing formwork to carry out the segmental construction of king-post, personnel channel generally adopts the method setting up steel pipe support.But after king-post has bound, steel pipe support carries out bridge deck and the construction of king-post affiliated facility after needing dismounting.As needed that in bridge operation process the suspension cable system on king-post checks, safeguards or king-post is carried out the constructions such as decoration, as set up, steel pipe support is time-consuming takes a lot of work again, and also suspension cable HPDE set can be had a negative impact in taking in the process of tearing open of steel pipe support, it is therefore desirable to a kind of inspection operation platform of research and development, this inspection operation platform need to meet lightweight, easy to operate, conveniently moving, safe and reliable, by the feature such as suspension cable or other barrier obstructions.
Utility model content
The purpose of this utility model is in that to provide a kind of bridge king-post that is suitable to that cable-stayed bridge cable system especially checks, safeguards or king-post is carried out the operating platform of detachable movable used during the constructions such as decoration.
nullTo achieve these goals,This utility model have employed techniques below scheme: the inspection platform of a kind of straight king-post of detachable cable-stayed bridge,Comprising: suspention operating platform、Dismantled and assembled platform and hoist system,Described suspention operating platform includes the two groups of semiorbicular suspension platforms built around king-post,Suspension platform is provided with steel wire hang structure,Described dismantled and assembled platform is arranged between two groups of semiorbicular suspension platforms,Dismantled and assembled platform is made up of some layers of platform,Every layer of platform is formed by two sections of dismountable linkage section docking,Connect with bearing pin between the suspension platform that every section of linkage section is adjacent,When linkage section is in mated condition,Suspension platform and dismantled and assembled platform form closed annular around king-post,Described hoist system is made up of with the shaped steel and pulley guider being arranged on king-post top the hoist engine being arranged on Cable-stayed Bridges,The steel wire rope of hoist engine is walked around described pulley guider and is connected with the steel wire hang hole suspension of suspension platform.
Described suspention operating platform, dismantled and assembled platform are the truss structure being welded by shaped steel and angle bar etc..
Described suspension platform is being provided with several jackings towards the one side of king-post, and jacking stays on king-post side by an adjusting screw rod thus carrying out stable to suspention operating platform.
Connect by ring flange and bolt are fixing between the linkage section that described dismantled and assembled platform is relative to each other.
Inspection platform of the present utility model is when running into the barriers such as suspension cable, it is possible to reach application target by dismantling its distachable platform.Operation workmen can hang its entrance suspention operating platform from bridge floor by hoist engine and construct.Suspention operating platform utilizes hoist system to move up and down, if running into suspension cable or other barriers can skip barrier by dismounting dismantled and assembled platform successively.This utility model adopts truss structure to significantly reduce the weight of inspection platform, and in use have only to by hoist system, suspention operating platform be moved up and down, contrast with setting up steel pipe support scheme along king-post surrounding, this scheme is greatly saved steel and puts into, greatly reduce labor intensity, effectively reduce the amount of labour of workmen, improve efficiency of construction and safety, improve economic benefit.This utility model is applicable to bridge king-post and cable-stayed bridge cable system especially checks, safeguards or king-post is carried out the construction use such as decoration.

Detailed description of the invention
The straight king-post inspection platform entirety of detachable cable-stayed bridge of the present utility model is square type truss structure, it is possible to use hoist engine is shifted up and down by wire rope suspensioning.
As it is shown in figure 1, inspection platform is mainly made up of 3 parts, Part I is suspention operating platform 1, and Part II is dismantled and assembled platform 2, Part III is hoist system 3.Suspention operating platform 1 and dismantled and assembled platform 2 are welded by shaped steel and angle bar, and total is truss structure, and it includes the two groups of semiorbicular suspension platforms built around king-post, and suspension platform is provided with steel wire hang clasp.Dismantled and assembled platform is arranged between two groups of semiorbicular suspension platforms.Dismantled and assembled platform is made up of some layers of platform, every layer of platform is formed by the method dish 2.4.3 shown in Fig. 4, Fig. 5 and bolt 2.4.2 docking by two sections of dismountable linkage sections, connect with bearing pin 2.4.1 between the suspension platform that every section of linkage section is adjacent, when linkage section is in mated condition, suspension platform and dismantled and assembled platform form closed annular around king-post.It is connected with clasp by steel wire rope between suspention operating platform 1 and hoist system 3.
Suspention operating platform 1 is made up of the steel truss being positioned at king-post surrounding and the jacking device 1.3 being fixed on steel truss.Steel truss is welded into truss structure by shaped steel and angle bar etc.;Jacking device 1.3 is then made up of jacking and the little steel pipe being welded on steel truss, as shown in Figure 1.When, in suspention operating platform 1 raising and lowering process, jacking device 1.3 is in and king-post side released state;After suspention operating platform arrival requires position, by regulating the adjusting nut on the screw rod of jacking device 1.3, make jacking and king-post side against also stress, it is ensured that suspention operating platform 1 does not produce to wave and affect normal operation.
Dismantled and assembled platform 2 haves three layers, and dismantled and assembled platform 2 is arranged according to position and the size of barrier, as shown in Figure 3.When suspending operating platform 1 in midair and running into barrier in moving up and down process, remove successively and 3 layers of dismounting platform are installed, but to keep 2 layers of dismounting platform to be in connection status all the time.
Hoist system 3 is made up of with the shaped steel and pulley guider 3.2 being arranged on tower top the hoist engine 3.1 being arranged on bridge floor.The hoist engine of bridge floor is arranged on the position not affecting normal traffic and fixes, the shaped steel of tower top and pulley guider 3.2 are arranged according to the size of suspention operating platform 1, the shaped steel of tower top is fixed on tower top built-in fitting, and the steel wire rope of hoist engine is walked around described pulley guider and is connected with the steel wire hang hole suspension of suspension platform.Staff only need to operate hoist engine at bridge floor just can carry out lift work to suspention operating platform 1, if running into suspension cable or other barriers in lift work process, (to be promoted to example) can be carried out according to the technological process in Fig. 8 a~each figure of 8e:
(1) such as Fig. 8 a, promote inspection platform, run into barrier;
