The invention belongs to the field of cranes with trolleys or hoisting seats walking on fixed or movable bridge frames or portal frames, and particularly relates to a movable hoisting device. In order to solve the technical problem that a movable hoisting device in the prior art can only adjust the height of materials through a lifting mechanism and cannot increase the height of a frame infinitely on the premise that the materials can pass through a narrow channel, the height of a hoisted object does not meet the requirement, the invention provides a movable hoisting device. Comprising a frame, a hoisting seat and a wheel mechanism, a first lifting mechanism used for controlling the hoisting seat to ascend and descend is arranged on the frame, and a hoisting tool is connected to the hoisting seat and comprises a connecting structure used for being connected with a hoisted object. The movable lifting device further comprises a second lifting mechanism used for directly controlling the connecting structure to ascend and descend or controlling the lifting appliance to ascend and descend so as to indirectly control the connecting structure to ascend and descend. The height of the lifted object is adjusted in a two-stage lifting mode so that the height of the lifted object can meet the requirement.
本发明属于具有在固定或可移动的桥架或门架上行走的台车或吊装座的起重机领域,特别是涉及一种移动式吊装装置。为了解决现有技术中的移动吊装装置仅能够靠升降机构调节物料的高度,在能够通过狭小的通道的前提下,不能够无限增大车架的高度,从而导致被起吊物的高度不符合要求的技术问题,本发明提供了一种移动式吊装装置,包括车架、吊装座和车轮机构,车架上设有用于控制吊装座升降的第一升降机构,吊装座上连接有吊具,吊具包括用于与被起吊物连接的连接结构,移动式吊装装置还包括用于直接控制连接结构升降或者用于控制吊具升降进而间接控制连接结构升降的第二升降机构。通过二级升降的方式调节被起吊物的高度以使被起吊物的高度符合要求。
