Rail transit height adjusting support and usage method
The invention relates to a rail transit height adjusting support and a usage method. The support can be adjusted up and down through the worm gear, the worm and the height adjusting plate of the worm gear, and high-precision and large-range height adjustment can be achieved. According to the technical scheme, the device comprises a box body, a thread sleeve is arranged in the box body, a stud extending out of the box body is arranged in the thread sleeve, the upper end of the stud is fixedly connected with a support, a locking eccentric nut with the lower end extending into the thread sleeve is arranged at the upper end of the thread sleeve, and trapezoidal threads on the locking eccentric nut and the thread sleeve are matched with trapezoidal threads on the circumference of the stud. A guide column is arranged in the stud, a small column body at the lower end of the guide column is fixedly connected with the box bottom plate, a large column body at the upper end of the guide column is in clearance fit with the inner wall of the stud, a worm gear and a worm which are meshed with each other are arranged between the thread sleeve and the inner wall of the box body, and the worm gear is arranged on the upper circumference of the thread sleeve; a plurality of height adjusting plates are arranged at the bottom of the box bottom plate, the peripheries of every two adjacent height adjusting plates are connected through a clamping base, and the ends of the clamping bases are locked with the height adjusting plates through locking screws.
本发明涉及一种轨道交通高低调整支座及使用方法。其通过涡轮蜗杆及其调高板实现支座的上下调整，可以实现高精度、大范围的高度调整。本发明采用的技术方案包括箱体，箱体内设置有螺套，螺套内设置有伸出于箱体的螺柱，螺柱的上端与支座固连，螺套的上端设置有下端伸入于螺套的锁紧偏心螺母，锁紧偏心螺母和螺套的上的梯形螺纹，与螺柱圆周上的梯形螺纹相配合，螺柱内设置有导向柱，导向柱下端小柱体与箱底板固连，上端大柱体与螺柱的内壁间隙配合，螺套与箱体内壁之间设置有相啮合的蜗轮、蜗杆，蜗轮设置于螺套的上部圆周上；箱底板的底部设置有若干个调高板，相邻两个调高板的四周通过卡紧座连接，卡紧座的端部通过锁紧螺杆与调高板锁紧。
