The invention discloses a bridge inhaul cable damping limiter. The limiter structurally comprises an upper limiting plate, a lower limiting plate, a damping ring and a fixing bolt, and due to the factthat a small amount of gravel is easily clamped between the upper limiting plate and an inhaul cable, the gravel between the inhaul cable and the limiting plate is blown away from a gap between the inhaul cable and the limiting plate through deformation gas diffusion of the upper damping ring. Sand and stone are collected through the bearing plate in the bottom damping ring, friction of the contact position of the inhaul cable and the limiting plate is reduced, the contact surface matching degree of the inhaul cable and the upper limiting plate is improved, and the damping limiting device cannormally fix and limit a steel component; the steel component is clamped and limited through contact of the bearing plate and the inhaul cable, and inhaul cable length change is reduced; and due to the fact that the exhaust hole is formed in the inner wall of the upper damping ring and is horizontal, the flowing speed of airflow is low, the airflow can flow along the inclined opening through thecooperation of the moving pipe in the exhaust hole and the airflow, the pushing force of the airflow is increased, and sand and stone particles are fully blown to fall off.
本发明公开了一种桥梁拉索减震限位器，其结构包括上限位板、下限位板、减震圈、固定螺栓，由于少量沙石易卡在上限位板与拉索之间，通过上减震圈形变气体扩散将拉索与限位板之间的沙石吹动离开之间的间隙，通过底减震圈内部的承接板将沙石收集，有利于减少拉索与限位板接触位置的摩擦，提高拉索与上限位板的接触面配合度，有利于减震限位装置对钢构件正常固定限位，并通过承接板与拉索接触对其夹持限位，有利于减少拉索长度改变，由于排气孔开设在上减震圈内壁，且为水平状，气流的流动速度缓慢，通过排气孔内部的移动管与气流配合移动，有利于气流沿着倾斜的开口流动，增大气流的推力，充分将沙石颗粒吹动掉落。
