Polishing frame for urban rail transit steel rail high-speed polishing vehicle
The invention discloses a polishing frame for an urban rail transit steel rail high-speed polishing vehicle. The polishing frame comprises a mounting frame which is a rectangular frame welded into a whole. The polishing beams are symmetrically arranged in the mounting frame in parallel; the grinding beam comprises grinding stone sets which are symmetrically arranged on the upper side and the lower side of the welding box. The lifting mechanisms are arranged at the two ends of the welding box. The polishing angle adjusting mechanism is arranged on the outer side of the lifting mechanism and connected with the mounting frame. According to the grinding device, the grinding beam can rapidly and reliably ascend and descend through the lifting mechanism, and certain pressing force can be provided for the grinding stone set in the grinding process; the steel rail surface grinding position is adjusted and controlled through the grinding angle adjusting mechanism, and accurate adjustment and wide coverage of the steel rail surface grinding position are achieved; the grinding stone set can be rapidly rotated and replaced through the rotating mechanism, the welding box body is locked after rotation is completed, the stability of the working state of the grinding beam in the working process is effectively guaranteed, and potential safety hazards caused by locking failure of the grinding beam in the working process are reduced.
本发明公开了用于城市轨道交通钢轨高速打磨车用打磨架，包括安装框架设置为焊接成整体的矩形框架；打磨梁对称平行设置于安装框架中；打磨梁包括磨石组对称设置于焊接箱体的上下两侧；升降机构设置于焊接箱体的两端；打磨角度调整机构设置于升降机构外侧，与安装框架连接。本发明通过升降机构使打磨梁能够快速可靠升降，能在打磨过程中为磨石组提供一定的压紧力；通过打磨角度调整机构对钢轨轨面打磨位置进行调整与控制，实现了钢轨轨面打磨位置的精确调整和广泛覆盖；通过旋转机构实现快速的磨石组旋转更换，并在旋转完成后锁死焊接箱体，有效的保证作业工作中打磨梁工作状态的稳定性，降低在作业过程中由于打磨梁锁死失效造成安全隐患。
