The invention discloses an electric single-beam crane with a locking mechanism for aloft work. The electric single-beam crane comprises a base and the locking mechanism, a support is fixed to the top of the base through a stud, a top frame is fixed to the top of the support through a stud, a bearing plate is slidably connected between rails, a sliding block is slidably connected into the bearing plate, the locking mechanism is arranged in the sliding block, rubber sheets are symmetrically arranged at the two sides of the sliding block, a supporting plate is fixed to the bottom of the sliding block through a nut, and winches are symmetrically fixed to the two sides of the lower end face of the supporting plate. According to the electric single-beam crane with the locking mechanism for aloft work, after the sliding block slides to a proper position, the corresponding winch needs to be used for completing the hoisting operation of a heavy object, before the hoisting operation is completed, a conical top block support moves upwards under the extension action of a corresponding electric telescopic column, at the moment, two corresponding abutting blocks are away from each other and abut against the bearing plate, the locking effect is conveniently achieved, and the hoisting operation of the heavy object is more stable.

    本发明公开了一种带有锁定机构的高空作业用电动单梁起重机,包括底座和锁定机构,所述底座的顶部通过双头螺栓固定有支架,且支架的顶部通过双头螺栓固定有顶架,所述轨道之间滑动连接有承载板,且承载板内滑动连接有滑块,所述锁定机构设置在滑块的内部,且滑块的两侧对称设置有橡胶片,所述滑块的底部通过螺母固定有支板,且支板下端面的两侧对称固定有卷扬机。该带有锁定机构的高空作业用电动单梁起重机,滑块滑动至合适的位置之后需要利用对应的卷扬机完成重物的吊放操作,在此之前,锥形顶块撑在对应电动伸缩柱的伸长作用下向上移动,此时对应的两个抵块相互远离并抵紧在承载板上,方便达到锁定的效果,使重物的吊放操作更加平稳。
