The invention relates to the technical field of frames, and discloses a combined type snow sweeper frame which comprises a frame assembly and an auxiliary assembly, the frame assembly comprises a longitudinal beam, a fixed cross beam is fixed to the longitudinal beam through bolts, a movable cross beam is arranged on the longitudinal beam, the auxiliary assembly is arranged on the longitudinal beam and the movable cross beam and comprises a moving part, the moving part comprises a reciprocating roller, and the reciprocating roller is inserted into the movable cross beam. A fixed shaft is fixed in the movable cross beam and internally meshed with the reciprocating roller, and a supporting block is fixed on the inner wall of the longitudinal beam. The longitudinal beam has the beneficial effects that when the longitudinal beam is subjected to impact force, the movable cross beam can move on the longitudinal beam, and the supporting point of the longitudinal beam is also changed, so that the stress which is possibly concentrated on some parts of the longitudinal beam originally can be dispersed to different areas, the stress is prevented from being concentrated on a certain fixed point for a long time, and the service life of the longitudinal beam is prolonged. Therefore, the risks of local fatigue damage and cracks of the longitudinal beam are greatly reduced, and the service life of the frame longitudinal beam is prolonged.
本发明涉及车架技术领域,公开了一种组合式除雪车车架,包括车架组件,包括纵梁,纵梁上通过螺栓固定有定横梁,纵梁上设置有动横梁,辅助组件,设置于纵梁和动横梁上,包括移动件,移动件包括往复辊,往复辊插接于动横梁内,动横梁内固定有固定轴,固定轴与往复辊内啮合,纵梁内壁固定有支撑块。本发明有益效果为:当纵梁在受到冲击力时,动横梁会在纵梁上移动,此时对纵梁的支撑点也随之改变,这有助于将原本可能集中在纵梁某些部位的应力分散到不同区域,避免了应力长时间集中在某个固定点,从而大大降低了纵梁出现局部疲劳损伤和裂纹的风险,延长了车架纵梁的使用寿命。
