Step 2: assembled steel truss girder in mobile device:
After setting-out, steel girder member bar position is determined, and complete segment steel truss girder by the assembled sequence of steel truss girder on the mobile device
It is assembled；
Step 3: hoist engine tethered sliding device keeps steel truss girder longitudinal steady mobile:
Displacement trolley longitudinal spacing is released, left and right sides sync pulling is carried out to mobile device using hoist engine until reaching lifting position
It sets, distraction procedure controls mobile device speed by hoist engine, and horizontal limit devices control mobile device lateral displacement, until arriving
Up to lifting position, steel truss girder vertical shift is completed.
The present invention has the advantage that realizing what large-tonnage steel trusses segment was longitudinally steadily moved the invention discloses a kind of
Device；It is made of support pad steel case, horizontal limit devices, rolling bearing, displacement trolley, the following steps are included: (1) is mobile when implementation
The processing of device；(2) assembled steel truss girder in mobile device；(3) hoist engine tethered sliding device keeps steel truss girder longitudinal steady mobile；
Implementation through the invention can satisfy steady vertical shift of the large-tonnage steel trusses under narrow space, and using the method for the present apparatus
Compared to traditional steel truss girder vertical shift method advantage are as follows: 1) fastly, five minutes or so 20 meters or so removable；2) surely, limiting device can
It makes steel truss girder two sides parallel lines mobile, avoids mobile device displacement in two sides is asynchronous from leading to deviation and be stuck in track；3) it saves,
System can be repeated, be recycled, at low cost, easy to operate to save manually.
Therefore the present invention utilizes mobile device two sides horizontal limit devices, allows and is displaced in trolley moving process and can be always maintained at
Straight line walking, does not rub with the track edge of a wing, avoids displacement trolley deviation.
In addition, for the present invention compares conventional equipment, advantage are as follows:
1, the efficiency when present apparatus substantially increases large-tonnage steel trusses vertical shift.
2, system can be repeated, be recycled, at low cost, easy to operate to save manually.
