An engineering cart capable of preventing overturning comprises a circular truncated cone, a cylindrical horizontal cavity is formed in the center in the circular truncated cone, a control cavity is formed in the circular truncated cone and located on the lower side of the horizontal cavity, and four popup cavities are formed in the side, away from the horizontal cavity, in the circular truncatedcone in an annular array with the horizontal cavity as the center. A communicating cavity is formed between the popup cavities and the horizontal cavity in a communicating mode, four extending cavities are formed in the four popup cavities in the direction away from the horizontal cavity in a communicating mode, and a horizontal device for sensing the horizontal state of the cart is fixedly arranged in the middle of the lower wall of the horizontal cavity. According to the engineering cart, the vehicle body inclination direction is identified through a horizontal device. The clamping devices on the same side are opened through the levers to enable the compressed springs to be ejected out quickly, then the supporting devices are brought out synchronously, and meanwhile the supporting devices guide out the supporting mechanism contracted into the supporting cavity to the two sides through gear and rack transmission to abut against the ground and the box body, so that the vehicle body tobe turned over on one side is fixed.
本发明公开的一种能防止翻倒的工程推车,包括圆台,所述圆台内中心位置设有圆柱形的水平腔,所述圆台内且位于所述水平腔下侧设有控制腔,所述圆台内远离所述水平腔一侧以所述水平腔为中心环形阵列设有四个弹出腔,所述弹出腔与所述水平腔之间连通设有连通腔,四个所述弹出腔远离所述水平腔方向连通设有四个伸出腔,所述水平腔下壁中间位置固定设有感应推车水平状态的水平装置,本发明通过水平装置识别车体倾斜的方向,利用杠杆打开同侧卡紧装置使被压紧的弹簧快速弹出,进而将支撑装置同步带出,与此同时,支撑装置通过齿轮齿条传动,将收缩进支撑腔的支撑机构向两侧导出,进而抵住地面和箱体,使将要侧翻的车体固定。
