That is, in embodiment of the present invention, when determining the entity wind area of described weight-lifting equipment current institute handling article perpendicular to wind direction, the mode with reference to respective standard can be adopted to come automatically to estimate the entity wind area of described weight-lifting equipment current institute handling article perpendicular to wind direction according to the weight (or quality) of described weight-lifting equipment current institute handling article, or, also can adopt to carry on control setup 25 at described wind and corresponding outer input interface is set, to be received the mode of the wind area that hoisting personnel inputs according to the actual conditions of described weight-lifting equipment current institute handling article by this outer input interface, estimate the entity wind area of described weight-lifting equipment current institute handling article perpendicular to wind direction, the embodiment of the present invention is not limited in any way this.
Particularly, according to the incidence relation (specifically can with reference to the 3rd formula) between wind speed and height, described P hcan represent with following 4th formula:
P h＝0.625V 2＝0.625[V 0(H/H 0) n] 2＝0.625V 0 2(H/H 0) 2n＝P(H/H 0) 2n；
Wherein, V 0for the current arm support head wind speed of described weight-lifting equipment, H 0for the current arm support height of head of described weight-lifting equipment; V for converting obtained wind speed by the height of described weight-lifting equipment current institute handling article to jib head wind speed, jib head wind speed corresponding when the height by described weight-lifting equipment current institute handling article sees corresponding jib height of head as; H is the height of described weight-lifting equipment current institute handling article, n is the earth's surface friction coefficient (and its value can set according to actual conditions, be positioned at as being usually set to 0.1 ~ 0.4 interval and comprise any number etc. of this interval endpoint) of setting.
Wherein, above-mentioned relate to for reflecting that the 3rd formula of the incidence relation between wind speed and height can be expressed as:
V x=V 0(H x/ H 0) n, wherein, V 0for the current arm support head wind speed of described weight-lifting equipment, H 0for the current arm support height of head of described weight-lifting equipment, V xfor the jib head wind speed information corresponding with setting jib height of head, H xfor setting jib height of head, n is the earth's surface friction coefficient of setting.
Further, it should be noted that, in embodiment of the present invention, described wind carries control setup 25 and also can be used for according to the incidence relation (specifically can with reference to the 3rd formula) between wind speed and height, and the current arm support head wind speed of the current arm support height of head of described weight-lifting equipment and described weight-lifting equipment, jib head wind speed corresponding when determining that the jib of described weight-lifting equipment is in the different jib elevation angle, and in conjunction with the lift hook position of the described weight-lifting equipment under the corresponding jib elevation angle and the current lift heavy of described weight-lifting equipment, under calculating current lift heavy, the wind of described weight-lifting equipment under the different jib elevation angle carries, and, carry compare by the wind of described weight-lifting equipment under each jib elevation angle under the current lift heavy calculated being carried the most strong wind that can bear under the jib attitude corresponding to the corresponding jib elevation angle to the described weight-lifting equipment pre-set, the safe change angle scope corresponding to jib of described weight-lifting equipment under determining current lift heavy.
That is, because jib jib head when setting change angle range of motion is in different height, therefore, under current arm support head wind speed prerequisite under the known current arm support elevation angle or under the height of current arm support head place, by the incidence relation between the jib elevation angle and jib height of head, and the incidence relation between wind speed and height, the arm head wind speed at (namely under the different jib elevation angle) under can obtaining different change angle, and and then account form can be carried according to the wind described in the embodiment of the present invention, under obtaining same lift heavy, the wind of (namely under current lift heavy) described weight-lifting equipment under the different jib elevation angle carries, and, carry compare by the wind of described weight-lifting equipment under each jib elevation angle under the current lift heavy calculated being carried the most strong wind that can bear under the jib attitude corresponding to the corresponding jib elevation angle to the described weight-lifting equipment pre-set, the safe change angle scope corresponding to jib of described weight-lifting equipment under determining current lift heavy.
