Be provided with the first roll shaft dolly below the leading section of horizontal gird, the first roll shaft dolly is positioned on first guide rail beam, first guide rail beam is shelved on first sleeper, and the cylinder body of the first translation jack is fixedlyed connected with first guide rail beam, and the piston rod of the first translation jack and the first roll shaft dolly are hinged; Be provided with the second roll shaft dolly below the rearward end of horizontal gird, the second roll shaft dolly is positioned on second guide rail beam, second guide rail beam is shelved on second sleeper, and the cylinder body of the second translation jack is fixedlyed connected with second guide rail beam, and the piston rod of the second translation jack and the second roll shaft dolly are hinged; The first translation jack, the second translation jack are positioned at the same side of horizontal gird; During use, first sleeper is shelved on next case beam section to be adjusted, and second sleeper is shelved on the good case beam section of adjusted.
When Hydraulic Station (pump) to vertical-lift oil cylinder (totally 4) oiling, the piston rod jack-up that makes progress, case beam section to be adjusted is raised by raising rod and adjusting nut, removes to vertically move dolly 19 under the case beam section.Four stage translation jack are simultaneously to a direction action, the case beam section that promotes the to be raised adjustment that moves laterally; After adjusting to the right place, vertical-lift oil cylinder oil extraction retraction drops to case beam section on the guide rail 17 that vertically moves.
The beneficial effects of the utility model are: 1, adopt said structure, requisite space is little, and is easy to use.
2, all elements of formation the utility model device all are the existing common apparatus of prestressing force viaduct job site.Vertical-lift oil cylinder and supporting Hydraulic Station can be used and apply interim prestressed equipment, finish after the horizontal adjustment, just in time on the spot this case beam section are applied interim prestressed operation.Raising rod and adjusting nut can adopt fining twisted steel and supporting nut; The roll shaft dolly can be general with the roll shaft dolly that vertically moves in the dolly; Horizontal gird, guide rail beam can be welded with general steel plate.
