Fig. 2 A shows the device that controlled motion parts 300 move on horizontal x direction.This device is the inferior device of single-degree-of-freedom prestige, and controlled motion parts 300 move in horizontal x direction.Steel wire rope 400 comprises two strand steel wire ropes 401,402.24,34 is pulley on the moving component 300.Steel wire rope 401 is connected and fixed a little 22, passes pulley 24,25,28 successively and enters drive unit 101; Steel wire rope 402 is connected and fixed a little 32, passes 34,35 successively and enters drive unit 101.When drive unit tightens up steel wire rope 402, when loosening steel wire rope 401, moving component 300 moves right.When drive unit tightens up steel wire rope 401, when loosening steel wire rope 402, moving component 300 is moved to the left.
Fig. 2 B is the distortion of Fig. 2 A.Wherein fixing point 22,32 is changed to fixed pulley 2,3 respectively.31,30 is fixed pulley, and the steel wire rope 401,402 that is respectively applied to lead is connected to drive unit 102.When drive unit 101,102 is used, tighten up steel wire rope 402, when loosening steel wire rope 401, moving component 300 moves right.When drive unit 101,102 tightens up steel wire rope 401, when loosening steel wire rope 402, moving component 300 is moved to the left.
Fig. 3 A shows the device that controlled motion parts 300 move on vertical y direction.This device is the inferior device of single-degree-of-freedom prestige, and controlled motion parts 300 move in vertical y direction.Steel wire rope 400 comprises two strand steel wire ropes 403,404.64,66 is pulley on the moving component 300.Steel wire rope 403 is connected and fixed a little 65, passes pulley 66,68 successively and enters drive unit 601; Steel wire rope 404 is connected and fixed a little 62, passes pulley 64, pulley 63, pulley 67 successively and enters drive unit 601.When drive unit tightens up steel wire rope 404, when loosening steel wire rope 403, moving component 300 moves up.When drive unit tightens up steel wire rope 404, when loosening steel wire rope 403, moving component 300 moves down.
Fig. 3 B is the distortion of Fig. 3 A.Wherein fixing point 65,62 is changed to fixed pulley 5,6 respectively.61,60 is fixed pulley, and the steel wire rope 403,404 that is respectively applied to lead is connected to drive unit 602.When drive unit 601,602 is used, tighten up steel wire rope 404, when loosening steel wire rope 403, moving component 300 moves up.When drive unit 601,602 tightens up steel wire rope 403, when loosening steel wire rope 404, moving component 300 moves right.
Be understandable that drive unit can be installed on the moving component 300.Steel wire rope connects drive unit 100 by the fixed pulley that is fixed on the object.Also can reach identical goal of the invention.
It should be noted that described steel wire rope can be replaced by rope any in this area.Connect effect as long as can play.Fixed pulley also replaces with the device of other guiding.The number of fixed pulley is not fixed, and can adjust according to position or the service condition of employed drive unit.
By above-mentioned explanation as can be seen, in the middle of the invention of the present utility model, as long as after the fixed pulley of the inferior device of single-degree-of-freedom prestige had good positioning, can the accurate control in one direction of controlled motion parts to the control of rope by one or more drive unit.If realize the motion of horizontal plane, only need to set up the x direction in the horizontal direction respectively, this device of two frees degree of z direction is controlled the motion of horizontal x direction and the motion of z direction respectively and is got final product.If realize the motion up and down of vertical plane, only need set up the x direction in the horizontal direction, set up this device of two frees degree of y direction in the vertical direction, the motion of controlling horizontal direction and vertical direction respectively gets final product.Wherein the steel wire rope of solid line part can be controlled and moves up and down as shown in Figure 4, and the steel wire rope of dotted portion can be controlled side-to-side movement.When moving up and down, to the not influence of left and right sides controlling organization.During side-to-side movement to up and down also not influence of controlling organization.Simple and easy.
Those skilled in the art are appreciated that when needs are set up motion control in three dimensions by foregoing description, only need to use the inferior device of prestige of the present invention of three degree of freedom.Namely set up the single-degree-of-freedom control device of x axle y axle z axle simultaneously, get final product by fixed pulley controlled motion parts simultaneously.It will be appreciated that described three degree of freedom comprises horizontal xy axle on the traditional sense, the vertical orthogonal concept of z axle can also be based upon under the different condition of the xyz axle etc. of inclination, such as xy axle and off plumb situation.As long as can set up three different direction of motion the present invention can realize.Thought of the present invention and concept are not limited to three dimensions, the hyperspace that development in science and technology realizes after also comprising in addition.
Fig. 5 shows the installation situation of controlling three degrees of freedom of movement parts top sheave simultaneously.Described moving component is a square.Its 6 faces have been installed three groups of pulleys respectively, are used for the motion on three directions of control.That is, the pulley shown in the quadrangle is used for the side-to-side movement of controlled motion parts.Pulley shown in the triangle is used for the controlled motion parts and moves up and down.Pulley shown in the pentagon is used for seesawing of controlled motion parts.
In order to ensure safety, can set up the control device of fixed pulley at moving component 300.The position of drive unit is unfixed, can be installed on the moving component 300.The number of drive unit does not limit yet.Can in one degree of freedom one or more drive units be installed according to service condition.The inferior device of prestige of an arbitrarily free degree that realizes by the various combination of drive unit number all within the scope of the present invention like this.And moving component can be the people, video camera, perhaps any object that need move.
In a word, the above is preferred embodiment of the present invention only, is not for limiting protection scope of the present invention.Above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although with reference to above-described embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the present invention, and not breaking away from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
