Novel beam falling prevention device with buffering and energy dissipation functions and adjusting method of novel beam falling prevention device
The invention discloses a novel beam falling prevention device capable of buffering energy consumption and an adjusting method thereof, and belongs to the technical field of bridge engineering. Comprising a base, fork lugs, anti-shear pins, pull rods, buffer pieces, baffles and steel wire ropes. Under the action of pressure generated when the baffle is tensioned by the inhaul cable, buffering energy consumption is achieved through elastic-plastic deformation of the buffering piece; after the buffer piece reaches limit compression, the baffle and the base are in hard contact, and limiting with higher rigidity is achieved. According to the novel anti-beam-falling device with the structure, through elastic-plastic deformation of the buffering piece and hard contact of the baffle and the base, buffering energy consumption is achieved, and the novel anti-beam-falling device has high bearing and resetting capacity; as the steel wire rope is soft, the length can be adjusted at will, the limiting distance can be adjusted at will, the installation technology is simple, the beam body construction error tolerance rate is large, safety and reliability are achieved, applicability is high, and economical efficiency is good; the steel wire rope can be made of stainless steel and has good corrosion resistance and durability.
本发明公开了一种缓冲耗能新型防落梁装置及其调整方法，属于桥梁工程技术领域。包括底座、叉耳、抗剪销、拉杆、缓冲件、挡板、钢丝绳。所述挡板在被拉索拉紧所产生的压力作用下，通过缓冲件弹塑性变形来实现缓冲耗能；当缓冲件达到极限压缩后，挡板与底座之间硬接触，实现更大刚度的限位。采用此结构的新型防落梁装置通过缓冲件弹塑性变形和挡板与底座硬接触不仅实现了缓冲耗能，而且具有较强的承载和复位能力；由于钢丝绳较软，可以任意调整长度，可实现限位距离的任意调整，安装工艺简单，梁体施工误差容错率大且安全可靠，适用性强，经济性好；钢丝绳可采用不锈钢，防腐及耐久性好。
