Highway construction expansion joint cutting machine with protection mechanism and using method

TAN YAN / YU CHANGGANG

The invention relates to the technical field of construction equipment, and particularly discloses a highway construction expansion joint cutting machine with a protection mechanism, which comprises a moving assembly, a rotating assembly, a telescopic cylinder, a cutting assembly, a driving assembly, a distance adjusting assembly, a limiting assembly and a hydraulic cylinder, an output shaft of the telescopic cylinder is rotationally connected with the rotating assembly, and a detachable cutting assembly is arranged on the rotating assembly. A driving assembly is arranged on the rotating assembly, and the driving assembly is used for providing driving force for the rotating assembly; a limiting assembly is slidably arranged on the rotating assembly, a hydraulic cylinder is arranged on the rotating assembly, and an output shaft of the hydraulic cylinder is fixedly connected with the limiting assembly. The driving assembly drives the cutting assembly to rotate, and the output shaft of the telescopic cylinder pushes the rotating assembly to rotate on the moving assembly, so that the cutting depth is adjusted to meet the requirement, two cutting seams are cut at the same time, and the cutting efficiency is improved.

本发明涉及施工设备技术领域，具体公开一种带有防护机构的公路施工伸缩缝切割机，包括移动组件、转动组件、伸缩缸、切割组件、驱动组件、调距组件、限位组件和液压缸，移动组件上转动设置有转动组件，移动组件上设置有伸缩缸，伸缩缸的输出轴与转动组件转动连接，转动组件上设置有可拆卸的切割组件；转动组件上设置有驱动组件，驱动组件用于给转动组件提供驱动力；转动组件上滑动设置有限位组件，转动组件上设置有液压缸，液压缸的输出轴与限位组件固连。本发明的驱动组件带动切割组件转动，伸缩缸的输出轴推动转动组件在移动组件上转动，从而调节切割切割深度符合要求，实现同时两个切割缝的切割，提高切割效率。
