Rail transit height adjusting support
The invention relates to a rail transit height adjusting support. According to the technical scheme, the rail adjusting device comprises a box body, a threaded sleeve is arranged in the box body, a stud extending out of the box body is arranged in the threaded sleeve, a guide column is arranged in the stud, the upper end of the stud is fixedly connected with a support, and the lower end of the stud is fixedly connected with the guide column. A locking eccentric nut with the lower end embedded into the box body is arranged on the circumference of 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, trapezoidal threads are arranged on the upward circumference of a cylindrical boss at the lower end of the stud, and a guide notch is longitudinally formed in the inner surface of the stud. The guide notch is matched with a key arranged in a key slot at the large-diameter end of the guide post; the lower conical surface of the locking eccentric nut is matched with the conical surface of the threaded sleeve, trapezoidal threads matched with the stud are arranged on the inner walls of the locking eccentric nut and the threaded sleeve, a gear is fixedly arranged on the circumference of the threaded sleeve, and the gear is meshed with the gear set.
本发明涉及一种轨道交通高低调整支座。其可通过齿轮实现轨道的上下调整，可以实现高精度、大范围的高度调整，本发明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，螺柱内设置有导向柱，螺柱的上端与支座固连，螺柱的圆周上设置有下端嵌入箱体的锁紧偏心螺母，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，螺柱的下端圆柱凸台处向上的圆周上设置有梯形螺纹，螺柱的内表面纵向设置有导向槽口，导向槽口与设置于导向柱大径端键槽内的键相配合；锁紧偏心螺母的下锥面与螺套的锥面相配合，锁紧偏心螺母和螺套的内壁上设置有与螺柱相配合的梯形螺纹，所述的螺套的圆周上固设有齿轮，齿轮与齿轮组相啮合。
