Description
Technical field
The present invention relates to a kind of technology for bridge under Bridge cable engineering running line, particularly a kind of combined type transition running line cage based on bridge running line under cable.
Background technique
In Bridge cable engineering, cable testing bridge is positioned at bridge both sides bridge abdomen and hangs fixing, cable causes from bridge floor must be by one section of free face the bridge abdomen cable testing bridge of bridge floor below, site operation is except arranging at free face lower bridge operating platform, a difficult problem is controlled in bending radius when solving under cable that bridge lays, side pressure, damage etc., general mode is to adopt to set up steel pipe frame on lower bridge operating platform, and the interior multiple spot of support body is installed annular coaster and controlled.Yet described annular coaster need to arrange by complicated calculating and in-site modeling, in setting up procedure, if there is partial deviations, easily cause that Cable Bending Radius is too small, side pressure increases, damage cable; In addition, after annular coaster arranges, because cable is not located, in cable laying process, must adjust in real time position, waste time and energy, efficiency is low, and follow-up construction is numerous and diverse.
Summary of the invention
The object of the invention is to according to the deficiencies in the prior art part provide a kind of time saving and energy saving, efficiency is high, the combined type transition running line cage based on bridge running line under cable of easy damaged cable not.
The object of the invention is to realize by following approach:
Combined type transition running line cage based on bridge running line under cable, its structure outline is, include first section of running line cage, rear running line cage and a plurality of intermediate section running line cage, wherein, the Constitution Elements of first section of running line cage, rear running line cage and each intermediate section running line cage has included guide roller frame, angle iron frame and steel pipe; Described guide roller frame is triangle or square planar framework, every limit of framework is all provided with the dolioform pulley of a stringcourse indent, the pulley stringcourse on every limit forms the space of a similar round in framework, and this spatial area is adaptive with the cross-section of cable that will pass through; Described angle iron frame and guide roller frame are adaptive, are also triangle or quadra, and the angle steel of take forms as limit, on each angle steel, is reserved with connecting screw hole; Steel pipe couples together the two by connecting the corresponding vertex of guide roller frame and angle iron frame, thereby forms a kind of cage shape belfry;
Concrete, first section of running line cage is identical with rear running line basket structure, the steel pipe adopting is straight shape steel tube, and this first section of running line cage and rear running line cage are by straight shape steel tube and lay respectively at straight shape steel tube two ends and the guide roller frame being connected with this straight shape steel tube, an angle iron frame composition; The steel pipe that intermediate section running line cage adopts is fan-shaped steel pipe, and the two end part of this fan-shaped steel pipe are connected with respectively an angle iron frame, and guide roller frame is positioned at the neutral position of fan-shaped steel pipe;
The angle iron frame of first section of running line cage is screwed into connecting screw hole with the angle iron frame of intermediate section running line cage one end by bolt and is fixedly connected with, transition running line cage adopts a plurality of intermediate section running line cages to join end to end to form arc intermediate section, and the angle iron frame of the other end of last intermediate section running line cage is bolted to connection with the angle iron frame of rear running line cage.
After being sequentially connected with rear running line cage, first section of running line cage, arc intermediate section just formed the combined type transition running line cage for bridge running line under cable of the present invention.Wherein, can adjust as required the quantity of the intermediate section running line cage of arc intermediate section part, when making, also can be according to the radian size of fan-shaped steel pipe on the structure processing intermediate section running line cage of concrete bridge.During use, cable is introduced to the guide roller frame of first section of running line cage, under the drive of dolioform pulley and under Action of Gravity Field, cable sequentially passes the guide roller frame of a plurality of intermediate section running line cages in combined type transition running line cage, finally from the guide roller frame of rear running line cage, draw, complete bridge running line under cable.
First section of running line cage of the present invention, rear running line cage and intermediate section running line cage are all the component units of combined type transition running line cage; with modular structure, produce; during installation, can carry out according to actual needs combination in any; by manpower, can complete lower bridge Piecemeal erection fixes; or adopt after bridge floor segmentation series connection assembling; utilize the auxiliary lifting of crane to be fixed on operating platform; at lower bridge free face, form a full guard and lay passage, cable can penetrate the crane span structure that running line cage causes bridge abdomen below from bridge floor.Constructing operation is simple and convenient, time saving and energy saving, efficiency is high, and all primings in cage shape framework of cable, and running line cage plays to cable the effect that four directions surrounds, and is therefore difficult for being damaged to cable.
Described angle iron frame is fixedly connected with steel pipe by welding.Described guide roller frame is fixedly connected with steel pipe by welding.
Because the top of each angle iron frame and guide roller frame can be connected to steel pipe, every steel pipe all needs to connect a summit of a framework, owing to adopting modular design, so each module can be fixed connection by welding, to reach stable structure.And only need to be connected by bolt between module and module.
In sum, technical characterstic of the present invention is:
1, owing to adopting modular point to install, also can install by integrated molding, save complicated construction calculating and in-site modeling operation, effectively solve bridge bending radius, side pressure, damage etc. under cable and control a difficult problem; Simultaneously can also cost saving: adopt segmentation, combined type, solves when long part transports a difficult problem and can reduce freight and crane use machine-team rental expenses.
2, simple installation.Section is connected and adopts common galvanized bolt simple to operate with section, without by external impetus, equipment, only by manpower, also can complete to install and fix, time saving and energy saving.
3, use safety.Once-through can be installed, in cable laying process, need not by workmen, carry out the adjustment of secondary on-load again, guarantee construction safety; Improve construction operation efficiency simultaneously, reduce hand labor.
4, using scope is wide.The present invention can use at subterranean tunnel or similar engineering.
