High-speed grinding trolley for urban rail transit steel rails
The invention discloses a high-speed grinding trolley for urban rail transit steel rails, which comprises a grinding frame used for mounting and fixing all parts for realizing a grinding function, and a first lifting mechanism is respectively connected with a trolley body and the grinding frame and used for realizing lifting and descending of the grinding frame and providing pressing force. The polishing beam can be rapidly and reliably lifted through the second lifting mechanism; accurate adjustment and wide coverage of the steel rail surface grinding position are achieved through the grinding angle adjusting mechanism; the grinding stone group is rapidly rotated and replaced through the rotating mechanism and is locked after rotation is completed, and the stability of the working state of the grinding beam is guaranteed; lifting of the grinding frame is achieved through symmetrically-arranged fourth telescopic pieces, and the problems of device failure, uncontrollable state and the like caused by desynchrony in lifting operation are solved; and through cooperation of the suspension assembly and the suspension shaft, the lifted polishing frame is stably placed in the high-speed driving process, and the situation that the polishing frame falls on a steel rail or other dangerous situations occur when the lifting device after lifting fails is avoided.
本发明公开了用于城市轨道交通钢轨高速打磨小车，包括打磨架用于安装和固定实现打磨功能的各个部件，第一升降机构分别连接车体和打磨架，用于实现对所述打磨架的起升与下降，提供压紧力。本发明通过第二升降机构使打磨梁能够快速可靠的升降；通过打磨角度调整机构实现钢轨轨面打磨位置的精确调整和广泛覆盖；通过旋转机构实现磨石组快速旋转更换，在旋转完成后锁死，保证打磨梁工作状态的稳定性；通过对称设置的第四伸缩件实现打磨架起降，避免起降操作中的不同步带来的装置失效、状态不可控等问题；通过悬挂组件和悬挂轴的配合，在高速行驶过程中稳固放置起升后打磨架，避免起升后升降装置失效时打磨架出现掉落在钢轨上或其他危险情况。
