The invention relates to the technical field of auxiliary equipment of rail traffic engineering, in particular to a simple ladder truck for single-side high-altitude operation in a subway interval tunnel, which comprises a base and an extension table, and a first support frame and a second support frame are arranged at the top of the base. A lifting assembly used for sliding up and down is arranged between the first supporting frame and the second supporting frame, a rotating rod used for adjusting the extending table is arranged in the lifting assembly, and a first gear and an extending rod which are used for reverse lifting of the two sides are arranged in the lifting assembly. Lifting of the ladder truck is completed through the extension rod and the lifting assembly, and meanwhile single-side same-direction and two-direction lifting of the extension tables on the two sides is completed through the extension rod and the first gear.

    本发明涉及轨道交通工程辅助设备技术领域,具体地说,涉及一种用于地铁区间隧道内单侧高空作业的简易梯车,其包括底座和延伸台,所述底座的顶部设置有一号支撑架和二号支撑架,所述一号支撑架和二号支撑架之间设置有用于上下滑动的升降组件,所述升降组件内设置有用于调节延伸台的转杆,所述升降组件内设置有用于两侧反向升降的一号齿轮和延伸杆,本发明通过所述转杆的转动,利用所述延伸杆和升降组件完成对梯车的升降,同时利用所述延伸杆和一号齿轮完成对两侧延伸台的单侧同向和双向升降。
