Problems solved by technology
When the rope parallel mechanism is running, the terminal position changes, and the rope produces a position deviation through the fixed pulley, and the hoist mechanism will also bring a deviation in the change of the rope length. These deviations often lead to uneven stress on the rope in the parallel mechanism, and the length of the rope Hours of work prone to wear and tear
Even with the method of measuring instruments and closed-loop control, its accuracy is difficult to guarantee, and its real-time control is also a difficult problem

The invention relates to an automatic tracking steering transmission device of a rope parallel mechanism which is characterized in that the device comprises an endless rope transmission mechanism, a pulley steering tracking mechanism, a weight mechanism, a bracket, a base and a rope; the endless rope transmission mechanism and the bracket are respectively arranged at the two sides of the top of the base; the endless rope transmission mechanism comprises a wire-out driving wheel and a wire-out driven wheel; the wire-out driving wheel and the wire-out driven wheel are respectively processed withring grooves which have consistent multi-channel pitch circles and are independently sealed, and are staggered by half groove position when being installed; the pulley steering tracking mechanism comprises a bottom wire-out pulley, a hollow shaft seat, a hollow shaft, a rotating frame and a top wire-out pulley; the bottom wire-out pulley is arranged on the base at the outside of the bracket; thehollow shaft seat is fixed at the top of the bracket and arranged on the hollow shaft seat vertically and rotatablely by two bearings; the rotating frame is fixed on the hollow shaft; the top wire-outpulley is fixed on the rotating frame. The invention is an ideal transmission device of the rope parallel mechanism and can be widely applied to the rope transmission of various rope parallel mechanisms.
Description
technical field [0001] The invention relates to a transmission device, in particular to a cable parallel mechanism automatic tracking steering transmission device. Background technique [0002] Parallel mechanisms are attracting more and more attention and applications, but in the application of large-scale mechanisms, there will be problems such as low rigidity and limited force due to too long telescopic legs. like Figure 4 As shown, the combination of rope and parallel mechanism can provide large control force and large span. The rope parallel mechanism has the advantages of large working space, high load capacity, easy disassembly, reorganization, high modularity, low price and fast movement speed. Etc. At present, the cable parallel mechanism has been applied in the 500-meter radio telescope, which makes it possible to realize the small weight of the feed source of the large radio telescope. In the current rope parallel mechanism, the transmission mechanism basically...
