The invention relates to a high-protection lifting platform which comprises a base, a scissors mechanism, a platform body and a hydraulic device. The platform body is connected to the upper end of the base through the scissors mechanism; and the hydraulic device is used for driving the scissors mechanism to move to drive the platform body to lift. The high-protection lifting platform further comprises a bottom inclination angle detection unit and a control unit. The bottom inclination angle detection unit is connected with the base and used for detecting an included angle between the base and a horizontal plane and outputting a corresponding bottom angle signal; the control unit receives the bottom angle signal and outputs a corresponding height limiting signal according to the bottom angle signal; and the hydraulic device responds to the height limiting signal to limit power output of the hydraulic device and then limit a maximum height of the platform body through the scissors mechanism. For the high-protection lifting platform disclosed by the invention, the bottom inclination angle detection unit is arranged to detect inclination of the base and measure an inclination angle of the base, the control unit limits a lifting height of the lifting platform according to the inclination angle of the base, and the larger the inclination angle of the base is, the lower the lifting height to be limited is, so that the inclination tendency of the lifting platform is reduced.

    本申请涉及一种高防护性升降平台,其包括底座、剪叉机构、平台以及液压装置;平台通过剪叉机构连接于底座的上端;液压装置用于驱动剪叉机构动作,以带动平台升降;还包括底部倾角检测单元以及控制单元;底部倾角检测单元连接底座,用于检测底座与水平面的夹角,并输出对应的底部角度信号;控制单元接收底部角度信号,并依据底部角度信号输出对应的限高信号;液压装置响应于限高信号,以限制液压装置的动力输出,进而通过剪叉机构限制平台的最大高度。设置底部倾角检测单元以检测底座的倾斜,并测量底座的倾角,控制单元依据底座的倾角,限制升降平台的举升高度,且底座的倾角越大,限制举升高度越低,以降低升降平台倾倒的趋势。
