Straddle type track beam stepless height adjusting support
A straddle type track beam stepless height adjusting support comprises an upper base plate, a middle base plate, a plane friction pair, a lower base plate, a curved surface friction pair, a height adjusting stud, a wedge-shaped adjusting plate, a height adjusting cushion block and a bottom plate. A cavity is formed in the center of the lower portion of the lower base plate, the upper portion of the height adjusting stud is arranged in the cavity, a cavity is formed in the center of the upper portion of the bottom plate, the lower portion of the height adjusting stud is arranged in the cavity, and external threads matched with height adjusting threads of the bottom plate are arranged on the surface of the lower portion of the height adjusting stud. Two correspondingly arranged wedge-shaped adjusting plates and/or two correspondingly arranged height adjusting cushion blocks are arranged on the outer side of the height adjusting stud between the lower base plate and the bottom plate. By adopting a single trapezoidal thread transmission height adjusting structure and a wedge-shaped or cushion block height adjusting and pressure bearing structure, the stepless height adjusting function and the wedge-shaped or cushion block height adjusting and pressure bearing function of the support are achieved, and the defect that a thread height adjusting section structure of the support is prone to being damaged under the action of vertical loads for a long time is overcome.
一种跨座式轨道梁无级调高支座，包括上座板、中座板、平面摩擦副、下座板、曲面摩擦副、高度调节螺柱、楔形调整板、高度调整垫块和底板；下座板的下部中心设有空腔，在此空腔内设有高度调节螺柱的上部，底板的上部中心设有空腔，在此空腔内设置在高度调节螺柱的下部，高度调节螺柱的下部表面设有与底板调高螺纹相配合的外螺纹；在下座板与底板之间的高度调节螺柱的外侧设有两块对应设置的楔形调整板和/或两块对应设置的高度调整垫块。通过采用单梯形螺纹传动调高结构、楔形或垫块高度调节承压结构，实现支座的无级调高、楔形或垫块高度调整承压功能，避免了支座螺纹调高节结构长期在竖向荷载作用下易产生破坏的弊端。
