The invention relates to the technical field of spacecraft assembly, in particular to a large-diameter large-stroke light shield installation guide device which comprises a guide rod and a guide ring. The guide rod is vertically arranged, and the bottom end is suitable for being mounted on a star body; the guide ring sleeves the guide rod in a manner of moving up and down along the guide rod, and is suitable for being mounted on the outer wall of the bottom end of the light shield; in the lifting process with the stroke of 5400 mm, for the position above the star sensor and the stroke of about 4800 mm, an operator holds the light shield to stably descend, and for lifting near the protruding point of the star sensor, the descending direction of the light shield is restrained in the mode that the guide rod is matched with the guide ring, so that the shaking degree of the light shield is reduced as much as possible, and the stability of the light shield is improved. The distance between the light shield and the star sensor is kept stable, and the light shield is prevented from colliding with protruding parts such as the star sensor.

    本发明涉及航天器总装技术领域,尤其涉及一种大口径大行程遮光罩安装导向装置,包括导向杆和导向环;导向杆竖直设置,底端适用于安装于星体上;导向环可沿导向杆上下移动地套设于导向杆上,适用于安装于遮光罩的底端的外壁上;在行程为5400mm的吊装过程中,对于星敏以上位置,约4800mm的行程,由操作人员扶持遮光罩稳定下降,而对于星敏突出点附近的吊装,采用导向杆与导向环相配合的形式约束遮光罩的下降方向,尽可能降低遮光罩的晃动程度,使得遮光罩与星敏之间的距离保持稳定,避免遮光罩磕碰星敏等突出部件。
