The invention discloses a transverse telescopic lifting appliance supporting device, and relates to the technical field of supporting devices. A main transmission shaft is transversely erected on a main supporting frame; the rotation driving assembly is installed on one side of the main supporting frame. The opening and closing driving mechanism is provided with a hollow lead screw, the main transmission shaft is sleeved with the hollow lead screw in a matched mode, and a forward external thread and a reverse external thread which are distributed in the axial direction are symmetrically arranged on the periphery of the hollow lead screw; the left lead screw nut and the right lead screw nut are respectively in threaded embedded connection with the hollow lead screw; the hinge type supporting fork assembly is provided with a left supporting arm assembly and a right supporting arm assembly which are of symmetrical structures. The sliding thread transmission mode of the hollow lead screw, the left lead screw nut and the right lead screw nut is adopted for driving the left supporting arm assembly and the right supporting arm assembly to be closed and opened, in the limited use space, the supporting fork can stretch in or draw out from the lower end of a hoisted object, the use space is saved, and the application capacity of the bracket is enhanced.
本发明公开了一种横向伸缩式吊具托起装置,涉及托起装置技术领域,主传动轴横向架设在主支撑架上;旋转驱动组件安装在主支撑架的一侧;开合驱动机构具备空心丝杠,空心丝杠配套套设在主传动轴上,空心丝杠的外周上对称设有沿轴向方向分布的正向外螺纹和反向外螺纹;左丝杠螺母和右丝杠螺母,分别与空心丝杠螺纹嵌接;合页式托叉组件,具备对称结构的左托臂组件和右托臂组件。本发明采用空心丝杠和左丝杠螺母和右丝杠螺母的滑动式螺纹传动方式来驱动左托臂组件和右托臂组件的合开,在有限的使用空间下,有利于托叉从被吊物下端伸入或抽出,节省了使用空间,增强了托架的适用能力。
