Telescopic device with buffering function

Abstract

The invention provides a telescopic device with a buffering function. The telescopic device comprises a device base. The main structure of the upper end of the device base is a first-stage sleeve. A second-stage sleeve is embedded in the first-stage sleeve. A third-stage sleeve is embedded in the second-stage sleeve. A gear lead screw shaft in the middle can make a lead screw nut drive the second-stage sleeve to move under the driving of a driving motor set; the driving motor set drives an inhaul cable take-up and pay-off wheel to take up and pay off an inhaul cable at the same time, so that the inhaul cable and a stretching compression spring between the second-stage sleeve and the third-stage sleeve are combined to make the third-stage sleeve move; the stretching compression spring has the buffering function when in a stretching-out state. According to the telescopic device with the buffering function, under the conditions of a small layout space and a narrow weight range, a capturing device installed at the upper end of the telescopic device can be stretched out or retracted, and axial buffering in the capturing process can also be achieved, so that favorable conditions are provided for capturing a target aircraft successfully; the telescopic device has the advantages that multiple functions are achieved, the structure is simple, and movement is reliable.

Description

technical field [0001] The invention relates to the technical field of telescopic device design, in particular to a telescopic device with a buffer function. Background technique [0002] With the increasing demand for capture and docking between space vehicles, especially under the limited load space and weight range, it is required to extend the capture device and complete the axial force buffer during the capture process of the two aircraft, and then in the two After the first aircraft completes the capture, the zoom-in operation of the two spacecraft is realized. [0003] At present, the telescoping device of the spacecraft capture device is in the initial preliminary research stage, and it is not yet possible to extend or retract the capture device in a small layout space and weight range, but also to achieve the axial buffer function, so as to provide The capture device provides convenient conditions for successfully capturing the target aircraft.
