The invention belongs to the field of manned aerospace engineering space station systems, and particularly relates to an in-orbit operation labor-saving device for a load supporting frame in a space station cabin. The device comprises an in-cabin load supporting frame, a fixed adapter, a labor-saving mechanism, non-disengagement screws and corner fittings, the corner fittings are arranged at the bottom and the top of the in-cabin load supporting frame, and all the corner fittings are connected with a standard interface of a space station cabin section through the non-disengagement screws; andthe labor-saving mechanism is arranged on the fixed adapter, the fixed adapter is connected with the in-cabin load supporting frame, so that the labor-saving mechanism corresponds to the non-disengagement screws on the corner pieces, and the labor-saving mechanism tightens or loosens the non-disengagement screws through torque multiplication, thereby assembly and disassembly of the in-cabin load supporting frame are achieved. Efficient torque and rotating motion transmission can be achieved, the beneficial effects of single input and two-way output are achieved, and the requirements of astronauts for on-orbit operation capacity and torque and operation space needed by screw disassembling and assembling are met.
本发明属于载人航天工程空间站系统领域,具体地说是一种空间站舱内载荷支撑框架在轨操作省力装置。包括舱内载荷支撑框架、固定转接件、省力机构、不脱出螺钉及角件,其中舱内载荷支撑框架的底部及顶部均设有角件,各角件通过不脱出螺钉与空间站舱段标准接口连接;省力机构设置于固定转接件上,固定转接件与舱内载荷支撑框架连接,使省力机构与角件上的不脱出螺钉相对应,省力机构通过扭矩倍增拧紧或松开不脱出螺钉,从而实现舱内载荷支撑框架的装拆。本发明可实现高效的扭矩和转动运动传递,还具有单输入、双向输出的特点,满足宇航员在轨操作能力和拆装螺钉所需扭矩及操作空间要求。
