Three-axis air flotation platform comprehensive simulation system large-angle rotary cable drag chain device

Abstract

The invention aims at providing a wide-angle rotation cable drag chain device of a three-axis air bearing table comprehensive simulation system. The wide-angle rotation cable drag chain device comprises a free cable swing head, a cable drag chain pipe, a hanging rope, a bearing, a plurality of pin rollers, a deconcentrator and a concentrator. The free cable swing head is connected with the deconcentrator through the bearing. The deconcentrator is fixed to an outer ring rotating platform of an air bearing table. One end of the cable drag chain pipe is connected with the free cable swing head, and the other end of the cable drag chain pipe is connected with the concentrator. One end of the hanging rope and the deconcentrator are fixed through the free cable swing head and the bearing. The other end of the hanging rope is connected with the concentrator. The pin rollers are installed in an air bearing table base rotation area where a cable drag chain passes. A cable passes a cable hole of the air bearing table base below the concentrator and enters the face of the air bearing table. After surrounding a stand column of the air bearing table by one circle, the cable passes the free cable swing head and the bearing to be connected with the deconcentrator, and the cable is connected with corresponding equipment after passing the deconcentrator. The device is simple in principle, low in price, easy to achieve in project and convenient to maintain.

Description

technical field [0001] The invention relates to measurement technology, in particular to a large-angle rotary cable drag chain device for a three-axis air-floating table comprehensive simulation system. Background technique [0002] The special operating environment of the space vehicle makes the ground simulation test very important. The core equipment of the full physical ground simulation system developed for the space vehicle is the three-axis air bearing table. In some applications, it is necessary to install Rotating track, install corresponding equipment on the rotating track to follow the rotation, at this time, the cable of the equipment will have the demand for large-angle rotary towline, the space between the rotating track and the air bearing table is relatively narrow, commercial finished cable towlines are often used at this time It cannot meet the application requirements, so it is extremely urgent to design a large-angle slewing cable drag chain device that c...

Problems solved by technology

However, this drag chain cannot be applied to the narrow and large angle applications of the three-axis air bearing table

[0005] In addition, the mature drag chain products on the research market, such as IGUS, Jiabao, etc., cannot be applied due to the comprehensive requirements of the application for the radius of gyration, angle of rotation, and the number of cables.
