Embodiment 1

[0045] Such as Figure 4 As shown, the fixed adapter includes an upper fixed adapter 4 with a triangular structure, the upper fixed adapter 4 is installed and fixed on the upper left corner of the load support frame 3 in the cabin, and the fixing seat 501 is fixed on the upper fixed adapter 4 , realize the fixation of the labor-saving mechanism 5 and provide it with reaction support torque, at this time, the left wrench head 503-1 cooperates with the first screw 601 that does not come out; connect the head of the standard torque wrench with the input end of the worm shaft 506 and apply the active force Make it rotate counterclockwise, the worm shaft 506 and the worm wheel 508 mesh and transmit the rotational movement and torque to the left wrench head 503-1, and the left wrench head 503-1 rotates clockwise and drives the first non-extracting screw 601 matched with it to rotate together , the first non-protruding screw 601 makes the installation point of the load support frame ...

Embodiment 2

[0047] Such as Figure 5 As shown, the upper fixing adapter 4 moves horizontally for a certain distance to the right and is fixed with the reserved interface of the load support frame 3 in the cabin. , so that the left wrench head 503-1 cooperates with the second non-detachable screw 602; repeating the steps in the first embodiment can realize the tightening or loosening of the second non-detachable screw 602;

Embodiment 3

[0049] Such as Figure 6 As shown, the fixed adapter also includes a first lower fixed adapter 11, the first lower fixed adapter 11 is fixed at the left front lower corner of the load support frame 3 in the cabin, and the labor-saving mechanism 5 is fixed on the first lower Fix the adapter 11 and provide the reaction supporting moment for the labor-saving mechanism 5. At this time, the right wrench head 503-6 cooperates with the third non-prolapse screw 601; the third non-prolapse screw 601 makes the cabin The installation point of the internal load support frame 3 is tightened with the standard interface in the cabin of the space station; similar to the steps in the first embodiment, the head of the standard torque wrench is connected to the input end of the worm shaft 506 and the active force is applied to make it reverse. Clockwise or clockwise rotation can realize the tightening or loosening of the third non-extraction screw 603 .

Abstract

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.

Description

technical field [0001] The invention belongs to the field of manned space engineering space station systems, in particular to a labor-saving device for on-orbit operation of a load support frame in a space station cabin. Background technique [0002] The space station is mainly composed of the core cabin, two experimental cabins and cargo spacecraft and other airtight cabin sections. During the long-term on-orbit operation stage, many astronauts will stay in the space station for a long time, and will carry out large-scale multidisciplinary fields in each cabin section. A large number of space science research and application technology verification experiments. Among them, the load support frame provides fixed supports and standard load interfaces for various scientific instruments and auxiliary equipment. Therefore, the load support frame is a very important support facility in the space station cabin. [0003] The load support frame is connected and fixed with the space...
