Therefore be necessary the research carrying out high rigidity flexible rope pinch device, fully introduce sophisticated design theory, to obtain the flexible rope pinch device with low impact, high rigidity of superior performance.
Summary of the invention
For the demand, the object of this invention is to provide a kind of high rigidity flexible rope pinch device and using method thereof, the present invention has the features such as structure is simple, rigidity is high, alerting ability is large, to solve the problem that existing pinch device performance is not good, impact is large, cost is high.
According to an aspect of the present invention, a kind of flexible rope pinch device is provided, comprise the first installing component, movable block, tether assemblies, the second installing component, wherein, described first installing component is threaded to realize up-and-down movement by the first hand of helix with between movable block, the upper end of described tether assemblies is threaded to realize up-and-down movement by the second hand of helix with between movable block, first hand of helix is contrary with the second hand of helix, and the lower end of described tether assemblies is connected with the second installing component.
Preferably, described second installing component adopts pin-and-hole to be connected with the lower end of tether assemblies.
Preferably, described second installing component linkage interface is circular hole, and the lower end of described tether assemblies is the cylinder of the band shaft shoulder, and the cylinder of the described band shaft shoulder matches the movement limiting described tether assemblies with circular hole.
Preferably, described tether assemblies comprises flexible rope, and described flexible rope is made up of lamination coating.
Preferably, described movable block is arranged in described first installing component.
According to another aspect of the present invention, a kind of using method of above-mentioned flexible rope pinch device is also provided, the upper end of tether assemblies is connected to movable block, turns movable block simultaneously, make movable block increase or while decline, drive the upper end of tether assemblies synchronously rise or decline.
Owing to have employed above technical scheme, make the present invention compared to prior art, there is following advantage and good effect:
First, flexible rope pinch device provided by the present invention, takes into full account the user demand of deployable space structures in the design process, makes this type actuating device have the advantage that structure is simple, rigidity is high, alerting ability is large, has the feature of low impact during release.
Secondly, flexible rope pinch device of the present invention takes into full account the mounting interface requirement adapting to the multiple parts such as rod member, plate in the design process, as long as carry out adaptability revision to the first installing component, the second installing component, what just can meet different spacecraft installs and uses requirement, the decline of performance or the increase of quality can not be caused simultaneously, there is higher commonality, have a extensive future.
