Description
Technical field
The utility model relates to bridge extension joint, and is particularly a kind of for the manipulator that bridge extension joint elasticity locking strip is installed.
Background technology
Railway is the main artery of national economy, and society is served in railway transportation all the time, serves the common people.Along with fast development of national economy, country gives railway transportation with the standard of heavy task and Geng Gao more.Up to the present, the existing length of railroad lines in service of China reaches 9.1 ten thousand kilometers, kilometer surplus the seat 4000 surplus the bridge about 50,000.In newly-built railway, the ratio of bridge length overall the line is busy road length overall is more and more higher.The line is busy that the road always is about 88% as Beijing-Tianjin inter-city railway bridge length overall, and the line is busy that the road always is about 81% for Beijing-Shanghai High-Speed Railway bridge length overall.Except a small amount of employing is striden greatly the special construction, all the other the whole hole of prestressed concrete two-wire freely supported structures that adopt more, span commonly used is 32m, 24m, wherein span structure commonly used accounts for more than 90% of bridge length overall again.
Bridge is distortion such as the beam body is stressed, temperature in order to adapt to, and must keep somewhere flexible slit between the beam body.Therefore, the indwelling in flexible slit becomes the most important approach of the stained beam body of Deck Water Leakage burn into, bearing, inspection facility and pier etc.China railways bridge operation experience for many years shows, it is most of relevant with water damage that the various factors that influence the structure durability disease appear in bridge, as alkali-aggregate reaction, carbonation of concrete, the corrosion of reinforcing bar electrochemistry, acid rain destruction, freeze thawing circulation etc., bridge floor ponding drops along beam-ends simultaneously, directly becomes the prestress anchorage system of sewage corrosion beam end of body, the chief culprit of worsening maintenance maintenance condition.Stretching device is as the important ancillary facility of railroad bridge, and its major function is that the ponding that prevents rainwater or other bridge floor flows directly into the beam end of body, and performances such as the catchmenting of bridge end, draining, waterproof are played an important role.Suitable the bridge that also must satisfy two curb girder body necessity simultaneously is to the needs of, direction across bridge displacement, vertical displacement and rotation, and its quality, performance and easy replaceability will directly influence the durability of bed rearrangement bridge.
Bridge extension joint comprises water blocking tape, elasticity locking strip and the connection strap with locking slot structure.Connection strap is generally special-shaped steel bar member, is anchored on the beam body end face of both sides, shrinkage joint.The dual-side portion of water blocking tape is positioned at the locking slot of connection strap, is locked by the elasticity locking strip that is squeezed in the locking slot.When changing water blocking tape, should in locking slot, remove the elasticity locking strip earlier.When changing water blocking tape, can under the situation that half spoke is broken off a friendship, on the road surface, finish easily by the highway bridge stretching device.But the characteristics of railway operation are different from highway, the position that bridge extension joint is installed is also different, this stretching device is installed in below cover plate, quarrel stone and the track plate, building above will removing when needing to change like this after the adhesive waterproof tape of stretching device damages and will stop railway operation, this almost is impossible.
The utility model content
Technical problem to be solved in the utility model provides a kind of for the manipulator that bridge extension joint elasticity locking strip is installed, and stretching device elasticity locking strip can be installed easily not removing under the prerequisite of stretching device with upper cover plate, quarrel stone and track plate.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
The utility model is used for installing the manipulator of bridge extension joint elasticity locking strip, it is characterized in that: it comprises stayed mast and is positioned at a pair of pressure plare of its both sides, pressure plare, stayed mast and first connecting rod, second connecting rod are connected to form slider-crank mechanism, be set with guide plate at pressure plare, guide plate is provided with guiding and extrusion structure.
The beneficial effects of the utility model are not removing under the prerequisite of stretching device with upper cover plate, quarrel stone and track plate, stretching device elasticity locking strip to be installed easily; Simple in structure, easy to operate.

Fig. 3 is the use view that the utility model is used to install the manipulator of bridge extension joint elasticity locking strip.
Component shown in the figure, toponym and corresponding mark: stayed mast 10, chute 11a, slide block 11b, pulling force rope hook 11c; Pressure plare 11, positive stop lug boss 11a, extruding convex shoulder 11b, guide plate 12, guiding hook 12a, pre-crushing block 12b, crushing block 12c; First connecting rod 21, second connecting rod 22.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, the manipulator that the utility model is used for installation bridge extension joint elasticity locking strip comprises stayed mast 10 and a pair of pressure plare 11 that is positioned at its both sides, pressure plare 11, stayed mast 10 are connected to form slider-crank mechanism with first connecting rod 21, second connecting rod 22, be set with guide plate 12 at pressure plare 11, guide plate 12 is provided with guiding and extrusion structure.With reference to Fig. 3, when the elasticity locking strip was installed, along shrinkage joint bearing of trend pulling stayed mast 10, pressure plare 11 was horizontal outwards mobile with respect to stayed mast 10 axis, the elasticity locking strip is clamp-oned the locking slot of connection strap, need not remove stretching device with upper cover plate, quarrel stone and track plate.
With reference to Fig. 1, the two ends of described first connecting rod 21 are hinged with stayed mast 10, pressure plare 11 respectively, and stayed mast 10 has the chute 11a of longitudinal extension, and the two ends of second connecting rod 22 are hinged with pressure plare 11, the slide block 11b that is installed in the chute 11a respectively.See figures.1.and.2, the upper plate of pressure plare 11 is to the positive stop lug boss 11a with vertical epirelief, longitudinal extension, and the outside of positive stop lug boss 11a is the extruding convex shoulder 11b that crosses out.Behind the pulling stayed mast 10, pressure plare 11 is horizontal outwards mobile with respect to stayed mast 10 axis, withstand on until positive stop lug boss 11a on the connection strap lateral surface of locking slot top, push convex shoulder 11b and stretch into continuously extruded elasticity locking strip in the locking slot this moment, and it is in place.
With reference to Fig. 1, described guiding and extrusion structure comprise that fixed interval is arranged on guiding hook 12a and the pre-crushing block 12 of guide plate 12 front portions, by the outer elasticity locking strip of guiding hook 12a guiding locking slot, and by pre-crushing block 12 thereafter the elasticity locking strip is partly clamp-oned in the locking slot, the extruding convex shoulder 11b by pressure plare 11 outsides clamp-ons the elasticity locking strip in the locking slot fully again.Described guiding and extrusion structure also comprise the crushing block 12c that is fixedly installed on guide plate 12 rear portions, and the elasticity locking strip carries out shaping in the locking slot to clamp-oning fully by crushing block 12c.With reference to Fig. 1, the front end of described stayed mast 10 is equipped with pulling force rope hook 11c.
The above the utility model that just explains through diagrams is used for some principles of the manipulator of installation bridge extension joint elasticity locking strip, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
