Reversing device utilizing spring pushing locking

Abstract

The invention provides a reversing device utilizing spring pushing locking, wherein a detaching connector exposing load can be reversed, to be convenient for an astronaut to operate. A straight hole is formed in a guide pillar, a cylinder hole is formed in a shell, a cylindrical pin penetrates through the straight hole in the guide pillar to be connected with the cylinder hole in the shell, a small spring is arranged in the guide pillar; a positioning block is arranged at one side, close to the guide pillar, of the shell; the cylindrical pin is used for limiting the radial movement of the guide pillar, and limit the linear movement scope of the guide pillar in the straight hole; the small spring is in contact with a push rod, the push rod moves linearly to compress or release the small spring, the small spring compresses or releases to push the guide pillar to move, the push rod is in key connection with a bevel gear A, the bevel gear A is connected with the shell by a bearing and is meshed with a bevel gear B, the center of the bevel gear B is connected with the shell by a bearing, the tail end of the push rod is connected with a pressure lever by a large spring, the pressure lever is arranged at the center of a wedge surface, and the wedge surface is connected with the shell.

Description

technical field [0001] The invention belongs to the technical field of space maintenance tools, and relates to a reversing device for space astronauts. Background technique [0002] According to the overall plan of my country's manned spaceflight project, a space station will be built around 2020. my country's space station will carry out a large number of exposure load tests on the exposed platform of the space station. These exposed loads and the exposed platform of the space station are connected together through standard interface equipment. After the exposure load test is completed, the exposed load needs to be disassembled and removed from the platform so that a new exposed load can be replaced for the exposure test. Under normal circumstances, the exposure platform powers up the standard interface equipment, and the electric control of the equipment drives itself to remove the exposed load, and the mechanical arm assists to remove the exposed load. When the electric ...

AI Technical Summary

Problems solved by technology

Under normal circumstances, the exposed platform powers up the standard interface equipment, and the equipment is electronically controlled to drive its own movement to remove the exposed load, and the exposed load is assisted by the mechanical arm to remove the exposed load. When the electronic control drive of the standard interface equipment fails, the exposed load cannot be disassembled , in order not to affect the replacement of the new load, the astronauts need to go out of the cabin to disassemble the exposed load. There is a disassembly interface on the standard interface equipment, and the disassembly of the load can be completed only by providing a certain torque for the disassembly interface. Due to constraints such as the limited activity range of the astronauts and the small distance between the disassembly interface and the exposed platform, the astronauts cannot use the electric screwdriver, a general tool outside the vehicle, to directly transfer the torque to the disassembly interface of the standard interface equipment. Therefore, it is necessary to design a A reversing tool for reversing the disassembly interface, so that astronauts can operate the electric screwdriver to reduce the torque to the disassembly interface, and finally realize the disassembly of the exposed load
