Description
Technical field
The utility model is related to bridge construction fields, and in particular to a kind of movable positioning machine for steel box-girder installation
Structure.
Background technology
Installing steel box-girder on holder at present generally uses loop wheel machine or gantry crane to be mounted directly in place or specifying lifting
Steel box-girder is lifted on after holder sliding way using the sliding of support daraf(reciprocal of farad) in place, when installing steel box-girder using support daraf(reciprocal of farad), because of cunning by station
Frictional resistance is larger between road, will generate larger thrust to holder in steel box-girder heave, needs to add supporting structure
By force, increase stiffness of support, material requested is more, and economy is poor；And scene holder assembly workload is larger, construction worker
Labor intensity is higher；Dilatory method is flexible stress system, and installation positioning accuracy is poor.
Invention content
The utility model provides that a kind of installation positioning accuracy is high, improves construction effect to overcome the shortcomings of the above technology
The mobile positioning mechanism for steel box-girder installation of rate.
Technical solution is used by the utility model overcomes its technical problem：
A kind of mobile positioning mechanism for steel box-girder installation, including：Holder that construction site is set up is horizontally mounted
In on holder track, positioned at track upper end coaster, be placed in supratrochlear box beam and jack, the ass rotation
Several idler wheels are installed, the idler wheel rolling is set on track, and the tail end of the jack is hingedly connected by axis pin I with coaster
Connect, the head end of the jack be provided with the fixed lockable mechanism I of track locking, the tail end of the coaster is provided with and track
The fixed lockable mechanism of locking II.
Above-mentioned track is arranged at intervals with several jacks along its length, and the lockable mechanism I includes hinged by pin shaft II
It is installed on the holder of jack piston rod head end and the vertical lock pin II being plugged in holder, the lock pin II is opposite to be propped up
When frame slides into bottom, bottom is inserted into jack, and the lockable mechanism II includes the locking for being plugged in coaster tail end vertically
Pin I, when I opposite brackets of the lock pin slide into bottom, bottom is inserted into jack.
Preferably, above-mentioned jack is elliptical aperture.
The utility model has the beneficial effects that：When needing to push box beam movement, coaster tail end passes through lockable mechanism II and rail
Road locking is fixed, and the piston rod of jack stretches out, and after its piston rod all stretches out, the head end of jack is passed through lockable mechanism
I fixes the locking for releasing lockable mechanism II simultaneously with track locking, and the piston rod of jack is retracted, and jack is due to front end at this time
It is fixed, therefore its tail end pulls coaster to move forward along track.By constantly repeating above-mentioned action, realizes coaster and drive box beam
It is moved in place along track.Jack tail end is articulated and connected with coaster, therefore can prevent operation bite, and box beam steadily promotes, and pacifies
Full performance is good.The displacement sensor that can also be arranged on jack realizes steel box-girder installation and is accurately positioned.It is applied compared to tradition
Work method, this mobile positioning mechanism have the spies such as simple in structure, easy to operate, speed of application is fast, installation accuracy is high, safety is good
Point.

In figure, 1. holder, 2. track, 3. jack, 4. coaster, 5. idler wheel, 6. box beam, 7. jack, 8. axis pin I 9. pin
II 10. holder of axis, 11. lock pin, I 12. lock pin II.
Specific implementation mode
Below in conjunction with the accompanying drawings 1, attached drawing 2 is described further the utility model.
A kind of mobile positioning mechanism for steel box-girder installation, including：Holder 1 that construction site is set up, horizontal peace
Loaded on the track 2 on holder 1, the coaster 4 positioned at 2 upper end of track, the box beam 6 that is placed on coaster 4 and jack 7, under coaster 4
End is rotatablely equipped with several idler wheels 5, and the rolling of idler wheel 5 is set on track 2, and the tail end of jack 7 passes through axis pin I 8 and coaster 4
Articulated connection, the head end of jack 7 be provided with the fixed lockable mechanism I of 2 locking of track, the tail end of coaster 4 is provided with and rail
The fixed lockable mechanism of 2 locking of road II.When needing to push box beam movement, 4 tail end of coaster is locked by lockable mechanism II and track 2
It only fixes, the piston rod of jack 7 stretches out, and after its piston rod all stretches out, the head end of jack 7 is passed through lockable mechanism I
The locking for releasing lockable mechanism II simultaneously is fixed with 2 locking of track, the piston rod of jack 7 is retracted, and jack 7 is due to preceding at this time
End is fixed, therefore its tail end pulls coaster 4 to move forward along track 2.By constantly repeating above-mentioned action, 4 band of coaster is realized
Dynamic box beam 6 moves in place along track 2.7 tail end of jack is articulated and connected with coaster 4, therefore can prevent operation bite, box beam 6
It is steady to promote, it has a safety feature.It is accurate fixed that the displacement sensor that can also be arranged on jack 7 realizes steel box-girder installation
Position.Compared to conventional construction method, this mobile positioning mechanism is with simple in structure, easy to operate, speed of application is fast, installation accuracy
