The invention aims to provide a novel portal crane used for solving problems existing in the prior art. The novel portal crane comprises a support arranged above an elevator car door, a door plate hung on the support and sliding in the extending direction of the support, and a drive device installed on the support and driving the door plate. The support and the door plate are connected in a sliding manner through a guide device. The guide device comprises an upper rail, a lower rail and a guide block. The upper rail and the lower rail are connected with the door plate and the support correspondingly. The lower rail is provided with a groove with three sides surrounding the upper rail. The guide block is arranged on the lower surface of the upper rail and abuts against the bottom face of the groove to achieve rolling contact. By means of the elevator portal crane provided with the adjustable and stable guide device, while a gap for preventing bumping between the door plate and an elevator body can be reserved, the function of enabling the door plate to keep higher stability under the shaking circumstance is possessed, thus the guiding ability of the portal crane does not lose effecteasily, damage is not caused easily, and the maintenance performance and use performance are good.

    本发明的目的在于提供一种新型门机,用以解决现有技术中存在的问题,包括设于电梯轿厢门上方的支架、挂设于支架并沿其延伸方向滑动的门板以及安装于支架并驱动门板的驱动装置,支架与门板间通过导向装置实现滑动连接,导向装置包括上轨、下轨、导向块,上轨和下轨分别连接门板和支架,下轨具有呈三侧包围上轨的凹槽,导向块设于上轨的下表面且与凹槽底面止抵实现滚动接触。通过该具有可调稳定导向装置的电梯门机,可以在保留门板与电梯本体间的防止磕碰的间隙的同时,具有使得门板在晃动情况下保持较高的稳定性的功能,从而使得其导向能力不易失效、不易损坏。维护性能和使用性能好。
