The invention belongs to the technical field of engineering vehicles, and discloses a power assisting device for an engineering vehicle. The power assisting device comprises a cross beam, wherein cross beam brackets are mounted at the two ends of the bottom of the cross beam; a rotating shaft is movably connected between the two cross beam brackets through bearings; a connecting block is mounted in the middle of the outer wall of the rotating shaft; a hydraulic cylinder is fixed to the end, which is away from the rotating shaft, of the connecting block; a hydraulic rod is mounted in the position, which is away from one end of the connecting block, of the hydraulic cylinder; the bottom end of the hydraulic rod is connected with a fixed block; a ground gripping support is hinged to the bottom end of the fixed block; and the inner top end of the cross beam is fixedly connected with a driving motor through a bolt. Through cooperation of structures such as a lead screw, a threaded sleeve, arack and a gear, the rotating shaft can drive the hydraulic cylinder to rotate, so that the rotating angle of the hydraulic cylinder can be adjusted rapidly and stably, the supporting angle can be adjusted conveniently, the use is flexible and convenient, and the power assisting effect of the device is greatly improved.

    本发明属于工程车技术领域,且公开了一种工程车用助力装置,包括横梁,所述横梁的底部两端均安装有横梁托架,两个所述横梁托架之间通过轴承活动连接有转动轴,所述转动轴的外壁中间安装有连接块,所述连接块远离转动轴一端的位置处固定有液压缸,所述液压缸远离连接块一端的位置处安装有液压杆,所述液压杆的底端连接有固定块,所述固定块的底端铰接有抓地支架,所述横梁的内部顶端通过螺栓固定连接有驱动电机,本发明通过丝杆、螺套、齿条和齿轮等结构的配合,使得转动轴能够带动液压缸转动,从而能够快速且平稳的调节液压缸的转动角度,以便调整支撑角度,使用灵活方便,大大提高了装置的助力效果。
