Technical field
The present invention relates to a kind of more exchange device of tied arch bridge hanger rod, belong to the civil engineering area of maintenance.
Background technology
Bowstring arch bridge is a kind of typical bridge type in the arch bridge, and it is with outside static determinacy, and is inner indeterminate, under the lateral force effect, and the arch springing horizontal-less thrust, two ends access bridge height is low, to geology conditional request advantages of higher and finding broad application not.Suspension rod is one of main bearing member of bowstring arch bridge, and the lower end is connecting crossbeam, and the upper end is connecting arch rib, is playing the part of the bridge floor lotus is cut the important function that passes to arch rib.
In long-term use, various diseases can appear in suspension rod, mainly comprise: first: upper and lower anchor head concrete protection ftractures, comes off; Second: loosening, the inefficacy of anchoring, stripped thread; The the 3rd: ponding, grouting leakiness in the conduit; The 4th: protective jacket destroys aging, cracking, breakage; The 5th: rope axis off normal, short steeve is cut; The the 6th: steel strand of hanger rod or steel wire discontinuity; The 7th: tired fracture of wire appears in cable body.
The existence of these diseases of bowstring arch bridge makes the serious hidden danger of security presence of bridge.In early morning on November 7th, 2002, the little south gate bridge suspension rod in Yibin ruptures suddenly, causes that bridge two ends bridge floor collapses.As seen, the suspension rod of bowstring arch bridge such as untimely replacing will cause the bridge disaster, and still present more changing device to tied arch bridge hanger rod still lacks.
Summary of the invention
The objective of the invention is to design a kind of quick replacement device of tied arch bridge hanger rod, solve the problem that to change when suspension rod generation disease.
For achieving the above object, the invention provides more changing device of tied arch bridge hanger rod, it is characterized in that: comprise support device and computer data acquiring control system, described support device comprises threaded rod, the Bailey truss beam, shoulder pole girder, distribution beam, the feed-through hydraulic jack, the vertically-displacable sensor, described threaded rod is 4, be evenly arranged in suspension rod to be replaced place crossbeam around, one end of described every threaded rod is fixed on described crossbeam lower end by described shoulder pole girder, the threaded rod other end passes plate face hollow slab beam successively, the Bailey truss beam, distribution beam, the feed-through hydraulic jack, the vertically-displacable sensor, nut, described Bailey truss beam is placed on the upside of adjacent suspension rod place crossbeam, and described vertically-displacable sensor is connected with described computer data acquiring control system.
Also be provided with bearing beam between described Bailey truss beam and the described suspension rod to be replaced left and right sides crossbeam, described bearing beam is placed on the upside at the adjacent beams center line.
Described distribution beam is vertical perpendicular to the Bailey truss beam, and shoulder pole girder is perpendicular to the crossbeam under the suspension rod, and the Bailey truss beam is along vertical layout of bridge, and described threaded rod and suspension rod to be replaced are arranged in parallel.
The axis of described distribution beam, vertically-displacable jack, vertically-displacable load sensor and the dead in line of described threaded rod.
Apparatus of the present invention have the following advantages:
One, can adapt to different suspension rod spacings all kinds of bowstring arch bridges change Suo Zuoye.
Two, adopt the construction of load sensor and computer data acquiring control system exchange rope to monitor, controlled at any time, safety is good.
Three, adopt standard Bailey truss beam to underpin beam as bearing capacity, the standardization level height need not special manufacturing, and equipment cost is low.
Four, construction operation carries out on bridge floor, and operating surface is big, is convenient to mechanized, improves and changes rope efficient.
Description of drawings:
Fig. 1 is that tied arch bridge hanger rod of the present invention is changed the apparatus structure schematic diagram;
Fig. 2 is a replacing assembly of devices of the present invention;
Fig. 3 is the A-A sectional view of Fig. 1;
Wherein 1,Suspension rod; 2, Bailey truss beam; 3, shoulder pole girder; 4, distribution beam; 5, vertically-displacable jack; 6, vertically-displacable load sensor; 7, nut; 8, threaded rod; 9, computer data acquisition system; 12, crossbeam; 13, bearing beam.
The specific embodiment:
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
As Fig. 1, Fig. 2 and shown in Figure 3, this suspender replacement device is made up of Bailey truss beam 2, shoulder pole girder 3, distribution beam 4, vertically-displacable jack 5, vertically-displacable load sensor 6, nut 7, threaded rod 8, computer data acquisition system 9 and bearing beam 13.
Concrete arrangement, the present invention is erected between the adjacent suspension rod by Bailey truss beam 2, and be shelved on the bearing beam 13, bearing beam 13 is placed on the upside at the adjacent beams center line, it above the Bailey truss beam 2 distribution beam 4, feed-through hydraulic jack 5 places between distribution beam 4 and the vertically-displacable load sensor 6, layout one shoulder pole girder 3 below suspension rod 1 lower crossbeam 12 to be replaced, threaded rod 8 runs through open-core type sensor 6, feed-through hydraulic jack 5, distribution beam 4, Bailey truss beam 2, hollow slab beam 11, shoulder pole girder 3, the upper and lower side of threaded rod 8 are fixing by nut 7 respectively.
Vertically-displacable load sensor 6 is connected with computer data acquiring control system 9.Distribution beam 4 is vertical perpendicular to Bailey truss beam 2, and shoulder pole girder 3 is parallel to the crossbeam 12 of suspension rod 1 over against the below, and Bailey truss beam 2 directions are parallel to the vertical of bridge.Threaded rod 8 is parallel to suspension rod 1 so that stressed.
When the present invention works, comprise the steps:
The first step, the support device is installed---between the suspension rod of described suspension rod to be replaced 1 left and right sides, set up Bailey truss beam 2, the support device is installed in the next door of suspension rod 1 to be replaced, internal force size by 6 collections of computer data acquisition system 9 Real Time Observation vertically-displacable load sensors, when this internal force is not less than suspension rod 1 internal force to be replaced, the internal force of suspension rod 1 to be replaced is offloaded to zero, and feed-through hydraulic jack 5 applies the Load Transfer approach that active force makes progress and is: feed-through hydraulic jack 5 → vertically-displacable load sensor 6 → nut 7 → threaded rod 8 → shoulder pole girder 3 → crossbeam 12; The downward power pipeline of this active force is: feed-through hydraulic jack 5 → distribution beam 4 → Bailey truss beam 2 → bearing beam 13 → left and right sides crossbeam;
Second step, removal suspension rod 1 to be replaced, new suspension rod is installed---after suspension rod 1 internal force unloading to be replaced is zero, remove the anchor device at suspension rod to be replaced 1 two ends, with pulling equipment suspension rod 1 to be replaced is taken out, and new suspension rod is launched, installation in position is tightened new ground tackle;
In the 3rd step, loading---Bailey truss beam 2 internal force shift: Bailey truss beam 2 → new suspension rod; The active force of removal feed-through hydraulic jack progressively, load still transmit according to the described power pipeline of the first step, make the suspension rod of new replacing stressed, and replacing is finished.
Above-mentioned feed-through hydraulic jack 5 upwards acts on jacking and unloading downwards, all by the stress of computer data acquiring control system 9 monitoring threaded rods 8, measures the Suo Li of suspension rod 1 to be replaced simultaneously and changes later suspender force.
