Abstract
A step-pad hydraulic cylinder fixing device belongs to the hydraulic cylinder fixing device field and solves the problems of a conventional step-pad cylinder fixing device that a connection between each hydraulic cylinder trunnion bearing seat and each bolt is prone to breakage; and a hydraulic cylinder is easily disengaged. A jointed board is connected on the end part of a pressure board through level-keys and bolts in the hydraulic cylinder fixing device in the utility model. The step-pad hydraulic cylinder which is then placed in the jointed board is no longer equipped on the pressure board in a suspending way. Furthermore, a connecting board equipped on the top of the bearing seats of the step-pad hydraulic cylinder makes the open-seat sizes of the bearing seats ensured and prevents faults that a gap between bolt holes leads to radial movement of the bearing seats and further results in disconnection between the bearing seats and the bolts and disengagement of the hydraulic cylinder. Meanwhile, the rolling quality of thick boards is effectively improved.
Description
Technical field
The utility model relates to a kind of hydraulic cylinder fixture, refers in particular to a kind of fixture of step pad hydraulic cylinder.
Background technology
The structure of advanced step pad has been adopted in the rolling horizontal adjustment of heavy plate mill, promptly on the pressure plare on the heavy plate mill AGC oil cylinder, step pad is installed, this step pad is by the step pad Driven by Hydraulic Cylinder that is installed on the pressure plare, and the ladder backing plate can move around on pressure plare, bears roll-force.The width of each grade step pad is 200mm, and the height of each grade step pad is 15mm.
