The invention relates to a municipal road height limiting rod which comprises a cylindrical stand column, a cylindrical rotating block is rotationally connected to the upper end of the stand column, a plurality of transverse rods are arranged at the left end of the stand column, a ball head is fixed to the right end of each transverse rod, clamping plates are fixed to the positions, at the corresponding ends of the ball heads, of the adjacent transverse rods and the left end face of the rotating block, and the ball heads are arranged between the two clamping plates and can freely rotate. A through hole is coaxially formed in each transverse rod, an annular block is arranged at the upper end of the stand column and can move up and down and rotate along the stand column, a circular ring is fixed to the left end of the annular block, a pull rope is fixed in the through hole of the transverse rod on the leftmost side, and the right end of the pull rope sequentially penetrates through all the through holes and the left end face of the rotating block rightwards. A heavy block is fixed to the position, located on the lower side of the circular ring, of the pull rope. The height limiting rod is formed by connecting a plurality of sections of cross rods end to end, so that the length of a stress arm is reduced, the counter-acting force generated by inertia when the cross rods are impacted is greatly reduced, and the impact resistance of the height limiting rod is improved.
本发明涉及一种市政道路限高杆，包括立柱，立柱为圆柱形，立柱上端转动连接有一个圆柱形的转块，立柱左端有多个横杆，每个横杆右端均固定有球头，球头对应端的相邻横杆和转块左端面均固定有夹板，球头置于两夹板之间并能自由转动，每个横杆上同轴开设有一个通孔，立柱上端设置有一个环形块，环形块能沿立柱上下移动和旋转，环形块左端固定有一个圆环，最左侧横杆的通孔内固定有一个拉绳，拉绳右端向右依次贯穿所有通孔和转块左端面，并沿转块下端面伸出后贯穿圆环，拉绳位于圆环下侧位置固定有重块；通过将限高杆设置为多段横杆首尾连接构成，减小受力力臂长度，大大降低横杆被撞击时惯性所生成的反作用力，提高限高杆的抗撞击能力。
