The invention discloses an underbed supporting mechanism for engineering machinery. The underbed supporting mechanism for engineering machinery comprises an underbed plate of engineering machinery, wherein a main driving motor is fixed to the middle of the top surface of the underbed plate of engineering machinery, an output shaft of the main driving motor penetrates the bottom surface of the underbed plate of engineering machinery and is fixedly provided with a main driving gear, the bottom surfaces of the underbed plate of engineering machinery on two sides of the front part and the back part of the main driving gear are hinged to rotating shafts through a bearing, transmission gears are fixed to the bottom ends of the rotating shafts, and the four transmission gears are engaged to the main driving gear; and first rotating arms are fixed to the bottom surface of the transmission gear on the left side of the front part and the bottom surface of the transmission gear on the right sideof the back part. Two first rotating arms and two second rotating arms at the bottom of a ladder truck rotate simultaneously and an adjusting compressing mechanism stretches outside the underbed plateof engineering machinery, and then an adjusting vertical screw is rotated manually, so that an elastic anti-slide block leans against the ground to achieve fixed support. The underbed supporting mechanism is good in fixed supporting effect and high in efficiency, and reduces the labor amount greatly.

    本发明公开了一种工程机械用底架支撑机构,包括工程机械底架板,所述工程机械底架板的顶面中部固定有主驱动电机,主驱动电机的输出轴穿过工程机械底架板的底面并固定有主驱动齿轮,主驱动齿轮的前部和后部的两侧的工程机械底架板的底面均通过轴承铰接有转轴,转轴的底端均固定有传动齿轮,四个传动齿轮与主驱动齿轮相啮合;前部的左侧的传动齿轮的底面和后部的右侧的传动齿轮的底面均固定有第一转动臂。本发明可以自动将登高车的底部的两个第一转动臂和两个第二转动臂同时转动,将调节压紧机构伸出工程机械底架板,然后,人工将调节竖直螺杆转动,使得弹性防滑块压靠在地面上,实现固定支撑,其固定支撑效果好,效率高,大大降低人工劳动量。
