Anti-collision guardrail device
The invention discloses an anti-collision guardrail device. The anti-collision guardrail device comprises stand columns, a flexible corrugated pipe provided with an impact side and a guide side whichare distributed on the two sides in an axial direction, and buffering and energy-absorbing blocks. The buffering and energy-absorbing blocks are connected between the stand columns and the flexible corrugated pipe and are provided with first matching surfaces and second matching surfaces respectively which are oppositely arranged; the first matching surface of each buffering energy-absorbing blockis connected with the upper end of each stand column in a matched mode, the second matching surface of each buffering energy-absorbing block is connected with the guide side of the flexible corrugated pipe in a matched mode, the impact side points to the second matching surface; and the flexible corrugated pipe is filled with an energy buffering filler. When a travelling crane collides with the impact side of the flexible corrugated pipe, the energy buffering filler in the flexible corrugated pipe buffers and absorbs energy, redundant energy is transmitted to the guide side and transmitted tothe buffer energy absorption block through the second matching surfaces to be subjected to secondary energy buffer and absorption, and finally impact energy is absorbed by the stand columns with highrigidity. The anti-collision guardrail device has high rigidity, good buffering and energy absorbing performance and guiding performance, and the safety of people and vehicles is guaranteed.
本发明公开了一种防撞护栏装置，包括立柱；柔性波纹管，具有分布在轴向两侧的撞击侧和导向侧；以及缓冲吸能块，连接在立柱和柔性波纹管之间，缓冲吸能块具有相对设置的第一配合面和第二配合面，缓冲吸能块的第一配合面与立柱的上端部配合连接，述缓冲吸能块的第二配合面与柔性波纹管的导向侧配合连接，撞击侧指向第二配合面，柔性波纹管内填充有能量缓冲填充物。行车碰撞在柔性波纹管的撞击侧，柔性波纹管内的能量缓冲填充物缓冲和吸收能量，多余的能量传递至导向侧，经第二配合面传递给缓冲吸能块进行二次能量缓冲和吸收，最后由刚性较大的立柱吸收冲击能量。该防撞护栏装置具有较好的刚度、缓冲吸能性能和导向性能，确保了人车安全。
