The invention relates to the technical field of railway vehicles, and particularly discloses a telescopic adjusting device and a tread sweeper. The telescopic adjusting device comprises a shell, a telescopic rod and an adjusting assembly, the telescopic rod is arranged in a telescopic mode relative to the shell in the front-back direction, the adjusting assembly is arranged between the shell and the telescopic rod, and the adjusting assembly comprises a sleeve part, a nut part located on the front side of the sleeve part and a first elastic part located on the rear side of the sleeve part. The shell is provided with a first stopping face located between the sleeve piece and the nut piece and used for preventing the sleeve piece from moving forwards relative to the shell, and a second stopping face located on the front side of the nut piece and used for preventing the nut piece from moving forwards relative to the shell. And the third stop surface is positioned between the sleeve piece and the nut piece or on the rear side of the sleeve piece and is used for stopping the nut piece or the sleeve piece from moving backwards relative to the shell. When the telescopic adjusting device and the tread sweeper are used, the abrasion loss of the grinding block can be compensated so as to adjust the distance between the grinding block and the wheel tread, and the telescopic adjusting device and the tread sweeper are simple in structure and easy to manufacture.

    本发明涉及轨道车辆技术领域,具体公开了一种伸缩调节装置和踏面清扫器。其中,伸缩调节装置包括壳体、相对壳体沿前后方向可伸缩设置的伸缩杆、设置于壳体和伸缩杆之间的调节组件,调节组件包括、套筒件、位于套筒件前侧的螺母件、位于套筒件后侧的第一弹性件,壳体具有位于套筒件和螺母件之间以用于阻挡套筒件相对壳体前移的第一止挡面、位于螺母件前侧以用于阻挡螺母件相对壳体前移的第二止挡面、位于套筒件和螺母件之间或套筒件后侧以用于阻挡螺母件或套筒件相对壳体后移的第三止挡面。本发明提供的伸缩调节装置和踏面清扫器在使用时,能够对研磨块的磨损量进行补偿,以调节研磨块和车轮踏面之间的距离,且结构简单,制造容易。
