The invention provides a tailor-welded front lower protective connecting plate structure. The tailor-welded front lower protective connecting plate structure comprises a main body, side pieces, an ejector block, a guide groove, protective plates, a buffer groove, a mounting groove and an ejector rod, the main body is mounted on the outer side of the top end of the main body, and a connecting holeis formed in the top end of the main body; the rear end of the top block is of an inclined structure, and the rear end of the top block is connected with the side pieces in a welded mode; the protective plates are installed at the bottom and the side edges of the body, and connecting holes are formed in the two sides of the top ends of the protective plates. The protective plates are used for being directly installed at the front end of a frame girder, so that when the girder is impacted, the buffer groove is in contact with the grinder to assist the grinder to buffer the impact, the grinder is prevented from being directly damaged due to collision, the protective plates are of an L-shaped structure and can be used well at the front end of the grinder, and the buffer groove of the wavy structure is used for directly absorbing the impact force, and the impact force can be buffered in an auxiliary mode.

    本发明提供一种拼焊式前下防护连接板结构,包括主体,侧件,顶块,导向槽,护板,缓冲槽,安装槽和顶杆;所述主体为安装在主体的顶端外侧,且主体的顶端设有连接孔;所述顶块的后端为倾斜状结构,且顶块的后端通过焊接的方式与侧件相连接;所述护板安装在主体的底部与侧边,且护板的顶端两侧设有连接孔;护板是用来直接安装在车架大梁的前端的,使得大梁在受到撞击的时候,可以通过缓冲槽与大梁接触,从而辅助大梁缓冲冲击力,避免大梁直接受到撞击受损,而护板为L形结构,是为了可以更好的安装在大梁的前端使用,而波浪形结构的缓冲槽是用来直接吸收冲击力的,使得冲击力可以被辅助缓冲。
