Abstract
The invention relates to a canting-pull dragline error correcting device that includes external steel pipe, inner steel pipe, end seal board, sealing component, and filling material. The external steel pipe is outside the inner steel pipe, two ends of external steel pipe extending out of inner steel pipe a certain distance. The end seal board has two components, as well as the sealing component. The end seal board seals inner and external steel pipe with sealing component to form sealing cavity, the filling material is filled in it. The filling material could flow between the external steel pipe and the inner steel pipe. Adjusting the location of inner steel pipe, the axis of canting-pull dragline could be superposition with that of pre-buried pipe. It could be widely used in canting-pull bridge structure and arch bridge structure.
Description
Technical field
The present invention relates to a kind of cable-stayed bridge cable, relate in particular to a kind of cable stayed bridge skew-inhaul-cable deviation-rectifying device.Belong to the road and bridge technical field.
Background technology
At present, in the cable stayed bridge building course, owing to always have certain deviation during pre-pipe laying installing and locating, so drag-line is after installing and stretch-draw finishes, and the drag-line axis does not overlap (Fig. 1) with pre-buried tubular axis line.Sometimes both deviations are very big, cause drag-line to contact with pre-buried inside pipe wall when serious, cause shock absorber to install.The conventional method that addresses this problem at present is: under drag-line and the pre-discontiguous situation of pipe laying, shock absorber is arranged to eccentric type; Under drag-line and situation that pre-pipe laying contacts, cut pre-pipe laying and expose part at bridge floor, adjust after its angle integrally welded again.The former is because the departure degree of pre-pipe laying and drag-line can't know bridge construction for sure the time, so the eccentric degree of shock absorber can't precise design, and rectifying effect is unsatisfactory.The latter will cause workload to increase, pre-pipe laying strength reduction, defective such as appearance is of poor quality.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of skew-inhaul-cable deviation-rectifying device that can correct cable-stayed bridge cable and pre-pipe laying deviation is provided.
The object of the present invention is achieved like this: a kind of skew-inhaul-cable deviation-rectifying device is characterized in that it comprises: outer steel pipe, interior steel pipe, end-plate, seal and inserts,
Outside the steel pipe, interior steel pipe two ends one segment distance was exposed at outer steel pipe two ends in described outer steel pipe was placed in,
Described end-plate has two, is packaged in outer steel pipe both ends in the form of a ring,
Described seal has two, axially is connected between interior steel tube end part and the end-plate inner face,
Described end-plate, makes and forms the annular closed cavity between the inside and outside steel pipe inside and outside steel pipe potting with seal,
Described inserts is filled in the annular closed cavity that forms between the inside and outside steel pipe,
Skew-inhaul-cable deviation-rectifying device of the present invention, described seal are the telescopic rubber sealing ring.
Skew-inhaul-cable deviation-rectifying device of the present invention, described inserts are the quartz sand or the hard particles shape material of order several 10～60.
Owing to adopt said structure, inserts flows between steel pipe and the interior steel pipe outside.The position of steel pipe can make the suspension cable axis overlap with pre-buried tubular axis line in regulating, to reach the purpose of correcting the suspension cable deflection.Therefore the present invention's skew-inhaul-cable deviation-rectifying device can effectively be regulated the misalignment of axe of drag-line and pre-pipe laying, makes shock absorber easy for installation.

Among the figure: end-plate 1, outer steel pipe 2, inserts 3, sealing ring 4, interior steel pipe 5, shock absorber 6, suspension cable 7, pre-pipe laying 8.
The specific embodiment
Shown in Fig. 2～3, skew-inhaul-cable deviation-rectifying device of the present invention is made of outer steel pipe 2, interior steel pipe 5, end-plate 1, sealing ring 4 and inserts 3.Outside the steel pipe 5, interior steel pipe 5 two ends one segment distance was exposed at outer steel pipe 2 two ends in described outer steel pipe 2 was placed in.Described end-plate 1 has two, is packaged in outer steel pipe 2 both ends in the form of a ring.Described seal 4 has two, axially is connected between interior steel pipe 5 ends and end-plate 1 inner face.Described end-plate 1, makes and forms the annular closed cavity between the inside and outside steel pipe inside and outside steel pipe potting with seal 4.Described inserts 3 is filled in the annular closed cavity that forms between the inside and outside steel pipe.
Shown in Fig. 4～5, after suspension cable 7 passes deviation correcting device of the present invention, two halves formula shock absorber 6 is installed in the deviation correcting device between the steel pipe 5 and suspension cable 7.
Embodiment 1:
As shown in Figure 6, deviation correcting device of the present invention is positioned within the pre-pipe laying 8.The outer steel pipe 2 of deviation correcting device is integrally welded with pre-pipe laying 8.Under pre-pipe laying 8 and situation that the axis of suspension cable 7 does not overlap, on suspension cable 7, apply earlier external force it is moved to the opposite direction that is offset, shock absorber 6 can be installed in the deviation correcting device between the steel pipe 5 and suspension cable 7.Regulate the position of suspension cable 7 then, steel pipe 5 flowed inserts 3 outside and fills steel pipe 5 and the axis of shock absorber 7 and the dead in line of suspension cable 7 in making along the radial motion of suspension cable 7 in shock absorber 6 drove between steel pipe 2 and the interior steel pipe 5.After the external force of removing on the suspension cable 7, interior steel pipe 5 compresses inserts 3, thereby makes the dead in line of axis with the pre-pipe laying 8 of suspension cable 7.
Embodiment 2:
As shown in Figure 7, deviation correcting device of the present invention is positioned at outside the pre-pipe laying 8.The outer steel pipe of deviation correcting device is connected with pre-pipe laying 8 usefulness bolts by flange.
