It is as follows for the program analysis of above-mentioned the application:
For the ease of the transmission of extruding force, as shown in figure 3, first is less than 1 by the vertical-horizontal slope ratio x of pressure head;
First point discussion, in the first extrusion head and first by pressure head from equilbrium position to the state being located remotely from each other, if original state Under, the first extrusion head is contacted with first by both pressure heads, due to x be less than 1, far from when, the first extrusion head and first by Pressure head can cause the first connecting rope to be in certain tensional state during contact;But then return to equilbrium position to it During, first can be caused to be squeezed bad situation by pressure head.
But the first extrusion head under original state is not contacted with first by both pressure heads, not necessarily condition, because For the first connecting rope can be adjusted(3-1-2)In first pulley(3-1-1)With the first anchor(2-1-3)Part side To.
One ontology of component(2-1)And first extrusion head(2-1-1)Move right dL distances, considers the influence of pulley, the One is by the climb of pressure head:dy=dL/cosθ;θ indicates the first connecting rope under original state(3-1-2)In first pulley(3- 1-1)With the first anchor(2-1-3)Part and the direction of vibration of one ontology of component angle;
And the first extrusion head(2-1-1)Move right dL distances, can allow first climb dy1=dLx by pressure head
It needs to meet:Dy≤dy1 is just avoided that the situation of Fig. 4.
It is found that in the case of 1≤xcos θ, the problem of can avoid Fig. 4.
As the above analysis, at θ=0 °, 1≤x can just be met the requirements, however when 1≤x, and stress is difficult to realize, i.e., and the One extrusion head and the first pressure between by pressure head are excessive, may result in first hit by pressure head it is curved.
Therefore at θ=0 °, first is not contacted by pressure head with the first extrusion head under original state, is in contrast preferable Design.
Second point discussion, in the first extrusion head and first by pressure head from equilbrium position to state close to each other, then again It when returning to equilbrium position, needs to ensure, the first connecting rope(3-1-2)It remains relaxed state, is otherwise returning to balance When position, damping action is necessarily had, the main body design of this and the application are runed counter to.
It is moved to the left L distances in the first extrusion head, first by the downward distance of pressure head is Lx;θ=0 ° the case where Under, the relaxed length of the first connecting rope is:L-Lx, that is, in the case of θ=0 °, as long as x≤1, you can meet:It is flat returning to When weighing apparatus position, the effect of damping action not will produce.
Consider it is elongated in the case of, the difference in height of the anchored end of the center of circle of first pulley and the first anchor is u, first Extrusion head has been moved to the left L distances, and the radius of first pulley is r, and θ indicates the first connecting rope under original state(3-1-2) One pulley(3-1-1)With the first anchor(2-1-3)Part and the direction of vibration of one ontology of component angle, θ 1 indicate to Moved left L apart from when the first connecting rope(3-1-2)In first pulley(3-1-1)With the first anchor(2-1-3)Portion Divide the angle with the direction of vibration of one ontology of component;
Original state, the first extrusion head and first is by pressure head when being contacted with each other,
First by the downward distance of pressure head is Lx, and the relaxed length of the first connecting rope is:
[rθ+(u+rsinθ)/sinθ]-[rθ1+(u+rsinθ1)/sinθ1]-L·x(θ, θ 1 indicates radian)
Wherein, the method for solving of θ 1 is:
rsinθ1+(u+rcosθ1)cotθ1= rsinθ+(u+rcosθ)cotθ-L
It only needs to meet:[r θ+(u+rsin θ)/sin θ]-[r θ 1+ (u+rsin θ 1)/sin θ 1]-Lx >=0.
Above formula, it should for arbitrary L(Take positive number), should all meet and just may be used.
