The invention belongs to the technical field of working ladders, and particularly relates to an adjustable working ladder with a lifting platform. The adjustable working ladder comprises a bottom plate, universal wheels are fixedly connected to the lower end face of the bottom plate, two first mounting seats are fixedly connected to the front side wall and the rear side wall of the bottom plate, first electric telescopic rods are fixedly connected to the lower end faces of the two first mounting seats, and bases are fixedly connected to the bottom ends of the first electric telescopic rods; and two sets of fixing blocks are fixedly connected to the front end and the rear end of the upper end face of the bottom plate, a threaded rod with opposite threads is rotationally connected between the fixing blocks, driven gears are fixedly connected to the threaded rods, and four grooves are formed in the bottom plate. According to the adjustable working ladder, through the bases, a lifting frame, second electric telescopic rods, rotating rods, pedals, suction cups and an air pump, the angle of the working ladder can be automatically and flexibly adjusted, the working ladder is convenient touse, the working intensity of a user is reduced, the stability of the working ladder can be improved, and the safety performance is remarkably improved.

    本发明属于工作梯技术领域,尤其为一种带升降平台可调节的工作梯,包括底板,所述底板的下端面固定连接有万向轮,所述底板的前后侧壁上均固定连接有两个第一安装座,两个所述第一安装座的下端面均固定连接有第一电动伸缩杆,所述第一电动伸缩杆的底端固定连接有底座,所述底板上端面前后两端均固定连接有两组固定块,所述固定块之间均转动连接有一个带有相反螺纹的螺纹杆,所述螺纹杆上均固定连接有从动齿轮,所述底板上设有四个凹槽。本发明通过底座、升降架、第二电动伸缩杆、转杆、踏板、吸盘和抽气泵,能够对工作梯的角度进行自动化灵活调节,方便进行使用,降低使用人员的工作强度,能够提高工作梯的稳定性,显著提高安全性能。
