The invention discloses a deflection-preventive vibration avoiding system for a high-speed quay crane trolley. The deflection-preventive vibration avoiding system comprises a plurality of vibration avoiding devices, wherein the each vibration avoiding device comprises a connecting base and an oil-gas damper; the corresponding connecting base is fixedly arranged on a framework of the quay crane trolley; the corresponding oil-gas damper is horizontally arranged between the framework of the quay crane trolley and a support of a deflection-preventive wheel; and the corresponding connecting base is hinged to one end of the oil-gas damper, and the support of the deflection-preventive wheel is fixedly connected to the other end of the corresponding oil-gas damper. According to the deflection-preventive vibration avoiding system disclosed by the invention, transverse vibration of the deflection-preventive wheel of the quay crane trolley is reduced, collision and extrusion between the deflection-preventive wheel and rails which are arranged on a quay crane large beam can be prevented, steady operation of the quay crane trolley is ensured, and the quay crane trolley and the quay crane structure can be protected, so that the operation speed of the quay crane trolley is further improved, and the loading and unloading efficiency of the quay crane is improved. Meanwhile, by utilizing common effect of the oil-gas damper and a rubber damper, the working performance cannot be prevented even if the oil-gas damper is too heat, and the problems of less rigidity and large deformation of rubber springs also can be overcome.

    本发明公开了一种高速岸桥小车防偏轮避振系统,包括若干避振装置,避振装置包括连接座和油气阻尼,连接座固定设于岸桥小车的框架上,油气阻尼水平布置于岸桥小车的框架和防偏轮的支架之间,油气阻尼的一端与连接座铰接,油气阻尼的另一端与防偏轮的支架固定连接。本发明降低了岸桥小车防偏轮的横向振动,防止防偏轮与岸桥大梁上的轨道侧面碰撞挤压,保证岸桥小车平稳运行,保护岸桥小车和岸桥结构。使岸桥小车的运行速度进一步提高,提高了岸桥的装卸效率。同时,利用油气阻尼和橡胶减振器共同作用,既可以防止油气阻尼过热影响工作性能,又克服了橡胶弹簧刚度小、变形大的问题。
