Abstract

The utility model provides a technical proposal of a large span cable bridge rack which can enlarge the hoisting span of cables. The utility model is characterized in that the utility model has two upright posts, one or two drag rope or draw rod is arranged between the two upright posts, the drag rope or the draw rod is provided with a plurality of slings or supporting rods which are respectively connected with respective hanging frames which are passed through by a bridge rack used for loading cables.

Description

The large span cable testing bridge

The utility model relates to a kind of cable hanging apparatus, especially for increasing the device that cable lifts a kind of large span cable testing bridge of span.

At present, the lifting of cable all is by upright supports, and mostly the cable lifting for needing large span is to adopt the method that increases column.So, the applicant has applied for patent No. 97206245.9 to Patent Office of the People's Republic of China, this patent is exactly a kind of technical scheme that increases cable lifting span, what adopt is the structure of approximate wire bridge, though this structure can improve the lifting span of cable greatly, there is certain difficulty in the construction at the scene.

The purpose of this utility model is exactly at existing difficulty in the prior art, and a kind of cable lifting span that increases is provided, by the large span cable testing bridge technical scheme of being convenient to construct.

For clearly demonstrating the technical characterstic of this programme, now by specific embodiment, and in conjunction with its accompanying drawing, the technical characterictic of this programme is described in detail.

Description of drawings;

Fig. 1 is a kind of example structure schematic diagram of using drag-line and hoist cable on crane span structure of the utility model;

Fig. 2 is a kind of example structure schematic diagram of using epirelief pull bar and hoist cable on crane span structure of the utility model;

Fig. 3 is a kind of example structure schematic diagram of using epirelief pull bar and pole under crane span structure of the utility model;

Fig. 4 be the utility model a kind of under crane span structure with the example structure schematic diagram of recessed pull bar and pole;

Fig. 5 is that Figure 1A-A is to analysing and observe the schematic diagram that adopts a drag-line;

Fig. 6 is that Figure 1A-A is to analysing and observe the schematic diagram that adopts two drag-lines;

Fig. 7 is that Fig. 3 B-B is to analysing and observe the schematic diagram that adopts a pull bar;

Fig. 8 is that Fig. 3 B-B is to analysing and observe the schematic diagram that adopts two pull bars.

As can be seen from Figure, this large span cable testing bridge has two columns 5, one to two drag-line or pull bar 3 are arranged between two columns 5, then have a plurality of hoist cables or pole 4 connecting separately hanging box 2 respectively on drag-line or pull bar 3, the crane span structure 1 that is used to load cable just passes in hanging box 2.As shown in Figure 1 be a kind of on crane span structure 1, with drag-line 3 in 5 connections of two columns, 3 one-tenth suspension cable shapes of drag-line, tight knot 7 is equipped with in order to adjust sag in two ends, the hoist cable 4 of several band tight knots 7 is housed on drag-line 3, and the lower end of hoist cable 4 is connected with hanging box 2, is lifting crane span structure 1 in the hanging box 2.Drag-line 3 can be one as shown in Figure 5, also can be two as shown in Figure 6.Fig. 2 then is on crane span structure 1, the pull bar 3 of making epirelief with steel pipe or channel-section steel connects between two columns 5, and the hoist cable 4 of several band tight knots 7 is housed on pull bar 3, and the lower end of hoist cable 4 is connected with hanging box 2, lifting crane span structure 1 in the hanging box 2, this pull bar 3 also can be with one or two.Fig. 3 represent below crane span structure 1, the pull bar 3 of making epirelief with steel pipe or channel-section steel connects between two columns 5, and several poles 4 are housed on pull bar 3, the last top of pole 4 is connected with hanging box 2, lifting crane span structure 1 in the hanging box 2, this pull bar 3 also can with one as Fig. 7, or two as Fig. 8.Fig. 4 represent then below crane span structure 1, make recessed pull bar 3 with steel pipe or channel-section steel and be connected between two columns 5, several poles 4 are housed on pull bar 3, the last top of pole 4 is connected with hanging box 2, lifting crane span structure 1 in the hanging box 2, this pull bar 3 also can be with one or two.In above-mentioned various forms of drag-lines or pull bar 3, the distance between described two hanging boxes 2 is less than or equals 6 meters.In addition, assisted suspension cable 6 also is housed, on every heel post 5, can adorns one to four assisted suspension cable 6, and on every assisted suspension cable 6 tight knot 7 is housed all at

crane span structure

1 and 5 on column.

By such scheme as can be seen, between two columns, be connected with the drag-line or the pull bar of recessed or epirelief, hoist cable or pole are housed on drag-line or pull bar, hoist cable or pole lift or prop up and adorning hanging box, the crane span structure that cable is housed is just supported by hanging box, this just can add large span as suspension bridge and Gong Qiao, so realize the crane cable of large span.When installing at the scene,, can reduce a large amount of adjustment work, on-the-spot just the installation more easily gone owing to be mostly prefabricated component.This shows that the utility model has substantive distinguishing features and progress than prior art, its effect also is conspicuous.
