The invention provides a tread sweeper with a gap adjusting device, and belongs to the technical field of railway vehicle equipment. The tread sweeper comprises a grinding block, a brake head, an air cylinder and a gap adjusting device arranged on an air cylinder body of the air cylinder. The tread sweeper further comprises a tooth-shaped component is fixedly arranged on a piston rod of the air cylinder. The gap adjusting device comprises: a movable plug pin and a movable plug pin, wherein a plug pin head of the movable plug pin can be meshed with the tooth-shaped component; a bolt seat limited in a gap adjusting device mounting hole of the air cylinder body; and an elastic component used for applying downward pressure towards the tooth-shaped component to the bolt seat. The upper end of the movable plug pin is sleeved with a guide groove, formed in the moving direction of the piston rod, of the plug pin base and can move forwards and backwards in the gap adjusting device installation hole along the guide groove along with the tooth-shaped component meshed with the movable plug pin. The tread sweeper is simple in structure and good in reliability, and the problems of bending, clamping stagnation and the like of the tooth-shaped component are solved.

    本发明提供一种具有间隙调整装置的踏面清扫器,属于轨道车辆装备技术领域。踏面清扫器,包括:研磨块、闸瓦托、气缸和设置在=气缸的气缸体上的间隙调整装置;并且还包括:固定设置在所述气缸的活塞杆上的齿状构件;所述间隙调整装置包括:活动插销,其插销头能够啮合于所述齿状构件;插销座,其被限位于气缸体的间隙调整装置安装孔中;以及弹性构件,其用于向所述插销座施加朝向所述齿状构件的下压力;其中,活动插销的上端被套装在插销座的沿活塞杆的运动方向而设置的导向槽中并且能够跟随其啮合的齿状构件在间隙调整装置安装孔内沿导向槽前后移动。本发明的踏面清扫器结构简单、可靠性好,不会发生齿状构件弯曲、卡滞等问题。
