The invention discloses a guiding, positioning and anti-floating device and method suitable for in-orbit maintenance of an outboard ORU. When the ORU equipment is replaced in a zero-gravity environment, the equipment needs to be prevented from floating away from a mounting surface through a device and a method. The guiding positioning anti-floating device is composed of a fixed positioning block and a spring type positioning block. Wherein the two fixed positioning blocks and the two spring type positioning blocks form a set and are respectively arranged on the diagonal sides (such as the left lower side and the right upper side) of ORU equipment. The invention discloses a guiding, positioning and anti-floating device and method suitable for on-orbit maintenance of an outboard ORU. The guiding, positioning and anti-floating device and method comprise the implementation steps of two stages, namely, the ground installation stage and the on-orbit installation stage. The ground installation stage comprises the steps of equipment installation, fixed positioning block installation, spring type positioning block installation, equipment disassembly and ground reinstallation equipment inspection, and the on-orbit installation stage comprises the steps of holding a universal handle to transfer equipment, attaching the equipment to the fixed positioning block, attaching the equipment to the spring type positioning block and on-orbit state confirmation.

    本发明公开了一种适用于舱外ORU在轨维修的导向定位防漂装置及方法。所述ORU设备在零重力环境下更换时需要通过一种装置及方法防止设备漂离安装面。所述导向定位防漂装置由固定式定位块、簧式定位块两部分组成。其中2件固定式定位块和2件簧式定位块为一组套,分别安装在ORU设备的对角侧(如左下和右上)。本发明所述的一种适用于舱外ORU在轨维修的导向定位防漂装置及方法,包括两个阶段的实施步骤,地面安装阶段与在轨安装阶段。地面安装阶段包括设备安装、安装固定式定位块、安装簧式定位块、拆下设备、地面复装设备检验,在轨安装阶段包括手持通用把手转移设备、设备贴合固定式定位块、设备贴合簧式定位块、在轨确认状态。
