Crawling ladder with adjustable height and inclination angle
The invention discloses a ladder stand with adjustable height and inclination angle. The ladder stand comprises a base, a jack, an upper stand column, a lower stand column, a lower inclined ladder rod and an upper inclined ladder rod, the base is a rectangular frame composed of four frames, the two corners of the left side of the base are each vertically provided with one lower stand column, and one upper stand column is inserted into each lower stand column in a sliding mode. The jack is fixed on the bottom beam between the two lower stand columns, and an ejector rod of the jack is connected with the top beam between the two upper stand columns; the two upper inclined ladder rods are inserted into the two lower inclined ladder rods in a sliding mode respectively, the top ends of the two upper inclined ladder rods are hinged to the top ends of the two upper stand columns respectively, and the bottom ends of the two lower inclined ladder rods are hinged to the two ends of the right frame of the base respectively. Small steps are arranged between the two upper inclined ladder rods at intervals, and large steps are arranged between the two lower inclined ladder rods at intervals. The jack is used as power, and the bottom end of the lower inclined ladder rod is connected with the angle adjusting mechanism, so that the height and inclination of the ladder stand are adjustable; the device is high in universality, safety and use flexibility, and the labor intensity of workers is reduced.
本发明公开了一种高度和倾角可调的爬梯，包括底座、千斤顶、上立柱、下立柱、下斜梯杆和上斜梯杆；底座为四根边框组成的长方形框架，其左侧两角各竖直设置一根下立柱，每根下立柱内滑动插入一根上立柱；千斤顶固定在两根下立柱之间的底梁上，其顶杆连接两根上立柱之间的顶梁；两根上斜梯杆分别滑动插入两根下斜梯杆内，两根上斜梯杆的顶端分别与两根上立柱的顶端铰接，两根下斜梯杆的底端分别铰接在底座右边框的两端；两根上斜梯杆之间间隔设有小台阶，两根下斜梯杆之间间隔设大台阶。本发明利用千斤顶作为动力,下斜梯杆底端连接角度调节机构,使爬梯高度、倾斜度可调；本发明通用性、安全性和使用灵活性高，降低了工作人员的劳动强度。
