The invention discloses an adjustable electric hoist portal crane, which relates to the technical field of electric hoist portal cranes and comprises a portal support and a step climbing assembly. In the using process, the upper cross beam is fixed to the opposite face of the top of the gate-type support, the main beam is matched with the electric cross rail on the top of the upper cross beam through the walking mechanisms on the two sides to achieve movement, and the main beam can move by adjusting the relative position of the main beam and the upper cross beam and conducting walking transmission on the lifting hoist through the controller. When the portal crane needs to walk on a step, the position of the main beam is adjusted front and back, so that the balance of the gravity center of the whole device is guaranteed, and the safety risk that the device is overturned due to the fact that the gravity center inclines backwards when the portal crane climbs the step is prevented; and the capacity of the portal crane for continuous step climbing and large-span step crossing is met, and the applicability is higher.
本发明公开了一种可调节的电动葫芦门式起重机,涉及电动葫芦门式起重机技术领域,包括门式支架和台阶攀爬组件。本发明使用过程中,门式支架顶部相对面固定有上横梁,主梁通过两侧行走机构与上横梁顶部电动横轨的配合实现移动,本申请主梁即可通过与上横梁的相对位置调整及通过控制器对起升葫芦的行走传动,将起升葫芦送至指定工位实现物料的吊装,还可将主梁作为配重块使用,当本申请门式起重机需要位于台阶行走时,通过主梁位置的前后调整,保障装置整体的重心平衡,防止在进行台阶攀爬时因重心后倾造成装置倾覆的安全风险,满足本申请门式起重机在进行连续台阶攀爬及大跨度台阶跨越的能力,适用性更强。
