Abstract
The utility model relates to a main girder bottom bending correction device, which comprises a support, a steel strand and a fixed block, characterized in that the fixed blocks are respectively arranged on the two supports, the steel strand winds on the fixed block, a cross-core tensioning jack is fixed on one of the supports through an anchorage, one end of the steel strand is inserted into the cross-core tensioning jack, the other end of the steel strand is fixed on the support. The main girder bottom bending correction device of the utility model has the advantages of simple structure, low cost, big tension, and a flexural main girder can be corrected and recovered to normal camber rapidly and conveniently.
Description
Technical field
The utility model relates to plant equipment, especially a kind of girder bending-down apparatus for correcting.
Background technology
Girder carries outside bearing and the influence of deadweight can produce flexural deformation, exceeds critical field sometimes, can cause potential safety hazard as untimely rectification.The employing screw rod and the turbine that have in the existing girder bending-down apparatus for correcting are paid transmission, though it can reach certain rectification effect, and its complex structure, cost of production height, and pulling force is smaller.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, cost is low, pulling force is big girder bending-down apparatus for correcting.
Girder bending-down apparatus for correcting of the present utility model comprises bearing, steel strand, fixed pulley, be characterized in all being equipped with on two bearings fixed pulley, steel strand are wrapped on the fixed pulley, vertically-displacable stretch-draw jack is fixed in wherein on the bearing by ground tackle, one end of steel strand is inserted in the vertically-displacable stretch-draw jack, and the other end is fixed on the bearing.
When girder bending-down apparatus for correcting of the present utility model uses, two bearings are separately fixed at the two ends of girder, by vertically-displacable stretch-draw jack extended steel twisted wire, the active force of steel strand is corrected the girder contraflexure.
Girder bending-down apparatus for correcting of the present utility model is simple in structure, cost is low, pulling force is big, can quickly and easily the girder of bending be corrected, and recovers normal camber.
