The invention relates to a self-propelled crank arm aerial work platform with a protection function, and belongs to the technical field of aerial work platforms, the self-propelled crank arm aerial work platform comprises a connecting arm arranged on a driving vehicle and a work platform, and the end, different from the driving vehicle, of the connecting arm is rotationally connected with an L-shaped base. The threaded rod is driven to rotate through the first driving motor, the movable block moves horizontally under the condition that the movable block is in threaded connection with the threaded rod, and fine horizontal adjustment on the working platform is facilitated. A second driving motor drives a gear to rotate, under the condition that the gear is meshed with a rack, the rack slides in a through hole, the angle of an L-shaped base is adjusted, the driving trolley is prevented from moving repeatedly, a second sliding block is in sliding connection with a groove in a rotating block, and it is guaranteed that the rotating block rotates stably. The fixing teeth are attached to the wall surface or the surface of an object, the operation platform is conveniently fixed, the limiting springs protect the operation platform, the operation platform is prevented from being separated from the L-shaped base, and use safety of the operation platform is guaranteed.

    本发明涉及一种带有防护功能的自行式曲臂高空作业平台,属于高空作业平台技术领域,包括驱动车上设置的连接臂和作业平台,所述连接臂异于驱动车的一端转动连接有L型底座。通过第一驱动电机驱动螺纹杆转动,在活动块与螺纹杆螺纹连接的情况下,使活动块水平运动,方便对作业平台进行细微水平调节。通过第二驱动电机带动齿轮转动,在齿轮与齿条啮合的情况下,使齿条在通孔内滑动,对L型底座的角度进行调节,避免驱动车反复挪动,第二滑块与转动块上的槽滑动连接,保证转动块转动的稳定。固定齿与墙面或物体表面贴合,方便对作业平台进行固定,限位弹簧对作业平台进行防护,避免作业平台与L型底座分离,保证作业平台的使用安全。
