Embodiment 1
[0082] Such as figure 1 A method for arranging multiple tackles in a steering field as shown, comprising the following steps:
[0083] Step 1: Determine the position of the steering field according to the positions of the traction field and the tension field, and measure the steering angle α;
[0084] By combining the positions of the traction field and the tension field, determine the position of the steering field according to the obstacles and areas that need to be avoided; after the steering field is confirmed, measure the steering angle α;
[0085] Step 2: Determine the number of tackles in the steering field according to the steering angle α;
[0086] After obtaining the steering angle α, determine the number of pulleys in the steering field according to the size of the steering angle α. In order to make the envelope angle not greater than 30°, the relationship between the number n of pulleys and the steering angle α satisfies the relation And the value of n is rounded ...
Embodiment 2
[0092] Such as Figure 2 to Figure 4 As shown, on the basis of Embodiment 1, when 30°≤α≤60°, the number of the tackles is two, and the two tackles are arranged symmetrically about the angle bisector of the supplementary angle γ of the steering angle α; When 60°≤α≤90°, the number of the blocks is three, the centers of the three blocks form an isosceles triangle, and the angle bisector of the angle γ is collinear with the axis of symmetry of the isosceles triangle; When 90°≤α≤120°, the number of the pulleys is four, the centers of the four pulleys form an isosceles trapezoid, and the angle bisector of the angle γ is collinear with the symmetry axis of the isosceles trapezoid.
[0093] The above settings enable the staff to quickly determine the overall position and layout of each tackle when arranging multiple tackles in the steering yard, and further improve the efficiency of the steering yard layout.
Embodiment 3
[0095] Such as figure 2 As shown, when the number of tackles is two, step three specifically includes the following steps:
[0096] (S11) The first block and the second block are arranged symmetrically about the angle bisector of the supplementary angle γ;
[0097] (S12) adjust the positions of the first tackle and the second tackle so that the center of circle of the first tackle is O 1 and the center O of the second tackle 2 The distance d between is:
[0098]
[0099] Among them, d AB is the center O of the first tackle 1 and the center O of the second pulley 2 The distance between the midpoint B of the connecting line and the measurement point A, r is the radius of the pulley. d AB The value of is determined artificially according to the actual working condition and the location of the measurement point.
