Portion is provided with jaw head, and on described jaw head jaw is provided with, and at the rear portion of described cylinder body anti-leak is provided with
End cover and sealing ring.
Described box type girder apparatus for correcting Special jack, is characterized in that：Described installing hole is bolted thousand
Jin top, described cylinder body, piston ring and piston body are internally formed the die cavities of two closings in cylinder body, the change of described die cavity
Change, promote the motion of ring belt piston body.
Described box type girder apparatus for correcting Special jack, the jaw head of described piston body head can clamp correction
The steel wire rope of device, described jaw head is completed by securing keys.
The beneficial effects of the utility model：
1. Special jack of the present utility model, can correct position deviation and the torsion of girder steel, and effect is good, economic reality
With, install simple.
Special jack of the present utility model, the torsion of rectifiable high-altitude heavy section steel girder steel, simplifies work progress,
Improve efficiency.
Special jack of the present utility model, has the advantages that rational in infrastructure, safe and reliable, the repeatable practicality of this product,
It is economical and practical.
Special jack of the present utility model, using large-tonnage hydraulic jack counter-force is applied, and the precision of adjustment can be accurate
To in 1 millimeter, while ensure that quality.
Special jack of the present utility model, using this fastener of welding production by fritter steel plate combination, reduces engineering
Cost.
Special jack of the present utility model, it is low from heavy and light, labour intensity, reach energy-saving purpose.

With installing hole, the inside of described cylinder body is provided with piston body 1, and described piston body is hollow structure, described piston
The stage casing of body is provided with piston ring 5, and the head of described piston body passes through front collet body screw thread 1-4 connection clip headgear 1-3, described
Collet sleeve inside jaw head 1-1 is installed, jaw 1-2 is installed on described jaw head, at the rear portion of described cylinder body
The end cover 2 and sealing ring 3 of anti-leak are installed.
Embodiment 2：
Box type girder apparatus for correcting Special jack according to embodiment 1, described installing hole is bolted
Jack, described cylinder body, piston ring and piston body are internally formed the die cavities of two closings in cylinder body, described die cavity
Change, promotes the motion of ring belt piston body.
Embodiment 3：
Box type girder apparatus for correcting Special jack according to embodiment 2, the jaw head of described piston body head
The steel wire rope of apparatus for correcting can be clamped, described jaw head is completed by securing keys 6.
Embodiment 4：
Box type girder apparatus for correcting Special jack according to embodiment 2, the using method of described jack is：
Apparatus for correcting two ends case girder steel correction body in jack is installed, during apparatus for correcting use, when case girder steel need into
During row correction, steel wire rope is loaded on the jaw head of piston body front end, by securing keys by the piston body opening in jack
Steel wire rope is clamped, it is possible to the deformation of case girder steel is corrected by the action of jack, when correction is finished, after the completion of welding,
Again by jack pressure release, steel wire rope is unclamped by unclamping securing keys, and steel wire rope is removed, then carry out next section of case girder steel
Correction work.
