Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to a positioning support device for roller replacement of a straightening machine. Background Art

[0002] At present, in the rolling process of medium and thick plates, due to the problems of poor plate shape such as edge waves and middle waves in the rolled plate, it is necessary to straighten the rolled steel plate to ensure the straightness of the steel plate. As the surface condition of the straightening roller deteriorates, the straightening roller needs to be replaced after a period of time. However, when replacing the straightening roller, the upper straightening roller frame hoisted by the crane shakes greatly and is difficult to dock with the lower straightening roller frame. The current method is to manually adjust the relative positions of the upper and lower straightening roller frames during the hoisting process, and then use bolts to fix four steel plates with threaded holes on the frames of the upper and lower straightening rollers to keep them relatively still. This positioning method requires frequent loading and unloading of bolts to install or remove the positioning steel plate, which has low operating efficiency. Moreover, after the straightening roller box is assembled into the straightening machine, the limited operating space makes it difficult to remove the positioning steel plate, affecting the production rhythm.

[0003] The bolts on the existing positioning steel plates will be subjected to great shear stress. In order to prevent the bolts from breaking, two heavier metal support beams will be placed on the bearing seat of the straightening roller before lifting the upper straightening roller frame to support the upper straightening roller frame. This operation is cumbersome and increases the risk of operation.

[0004] A patent document with publication number CN218361422U proposes a positioning support device for roller replacement of a straightening machine, which includes an upper straightening roller box and a lower straightening roller box, wherein the upper and lower straightening roller boxes are respectively provided with two corresponding reference holes on their operating side and transmission side; a positioning support device is installed in each of the corresponding upper roller box reference holes and lower roller box reference holes; the positioning support device includes a support body, an upper connecting pin is welded above the support body; a lower connecting pin is welded below the support body; and a gripping handle is installed on both sides of the support body. The utility model has a reasonable structure and can effectively meet the positioning and support requirements of roller replacement operation of the straightening machine.
