7.4.5. Editing of a beam of the back bridge

The scheme of editing of a beam of the back bridge

1 – the hydrocylinder;
2 – clamping a traverse;
3 – flange А.70172;
4 – a square;
5 – a press table;
6 – an emphasis;
7 – an indicator rack

1. Attach to each end of a beam flanges А.70172 (used for editing, instead of for check of beams) and establish it on support of a hydraulic press so that the ends clamping traverses 2 were in a zone of deformation of a beam. The most probable arrangement of a zone of deformation, on distance of 200-300 mm from end faces of flanges of a beam.
2. Establish a rack 7 with the indicator so that the indicator leg rested against the top part of a lateral surface of a flange, and the arrow of the indicator stood on the division equal to size of deformation of a beam, measured щупом at beam check. On the other hand beams establish or a rack with the indicator, or a square 4.
3. Having established under a beam (in a deformation zone) a restrictive emphasis 6, correct a hydraulic press a beam, consistently, in horizontal and vertical planes, supervising results of editing on the indicator or щупом on a square 4.
4. The maximum effort of a press at beam editing should not exceed 98 КН (10000 кгс) that there was no excessive deformation of section of a casing.
The prevention

At the height of the emphasis 6 which have been picked up correctly by practical consideration, a beam it is possible to correct without check by a square or the indicator.

5. Remove a beam from a press and check up it as it is specified above, having replaced flanges А.70172 with "verifying".
6. In the absence of the appropriate equipment as the exception, is supposed editing of a beam of the back bridge, consistently, from each party, but with obligatory check of deformation of a beam from both parties (subsection 7.4.4 see).
