如图1所示,该方法包括以下步骤:As shown in Figure 1, the method includes the following steps:
步骤S101,获取吊钩平台的多个支撑点位置,根据多个支撑点位置确定中间点位置。Step S101, obtaining multiple support point positions of the hook platform, and determining the intermediate point position according to the multiple support point positions.
本实施例中,一般来说轮胎式起重机有四个支腿,则将支腿的位置作为支撑点位置,根据支撑点位置和吊钩平台确定中心点位置,通过支撑点位置与中心点位置的距离差,控制其他支撑腿上升或下降直到各支撑点与中心点看齐,当支撑点达到中心点位置时平台即处于水平状态。In this embodiment, generally speaking, a rubber-tyred crane has four outriggers, and the position of the outriggers is used as the position of the support point, and the position of the center point is determined according to the position of the support point and the hook platform. If the distance is poor, control the other support legs to rise or fall until each support point is aligned with the center point. When the support point reaches the center point, the platform is in a horizontal state.
步骤S102,根据多个支撑点位置和中间点位置确定调整距离,根据调整距离得到调整时间,获取平台倾角,根据中间点位置对平台倾角进行修正,得到修正后的平台倾角。Step S102, determine the adjustment distance according to the positions of multiple support points and the intermediate point, obtain the adjustment time according to the adjustment distance, obtain the platform inclination, correct the platform inclination according to the intermediate point position, and obtain the corrected platform inclination.
本实施例中,建立平台坐标系,平台长为a,宽为b,支撑点Li=(xi,yi,zi)(i=1-4),L1=(0,0,0),L2=(a,0,0),L3=(a,b,0),L4=(0,b,0),中心点Z坐标是(a/2,b/2,0),调平之前进行预支撑,设初始倾角为α0和β0。In this embodiment, a platform coordinate system is established, the length of the platform is a, the width is b, the support point L i =(xi , y i ,zi ) (i=1-4), L 1 =(0,0, 0), L 2 = (a, 0, 0), L 3 = (a, b, 0), L 4 = (0, b, 0), the Z coordinate of the center point is (a/2, b/2, 0), perform pre-support before leveling, and set the initial inclination angles as α 0 and β 0 .
各个支撑点与中间点位置的距离差为:The distance difference between each support point and the middle point is:
总的调节距离为The total adjustment distance is
调节时间T由L1的位置与中间点位置之差大小决定,,The adjustment time T is determined by the difference between the position of L 1 and the position of the middle point,
其中,V是调节速度。Among them, V is the regulating speed.
此时,求得的调节时间中的调节速度是额定速度,后续对调节速度进行控制。At this time, the adjustment speed in the obtained adjustment time is the rated speed, and the adjustment speed is subsequently controlled.
不同的平台长宽不同,其中间点位置对平台倾角存在一定影响。Different platforms have different lengths and widths, and the position of the middle point has a certain influence on the inclination angle of the platform.
设定中间点位置为A,预设中间点位置数组A0(A1,A2,A3,A4),其中,A1、A2、A3、A4均为预设数值,且A1<A2<A3<A4;Set the position of the middle point as A, The preset intermediate point position array A0 (A1, A2, A3, A4), wherein, A1, A2, A3, A4 are all preset values, and A1<A2<A3<A4;
预设平台倾角修正系数数组Q0(Q1,Q2,Q3,Q4),其中,Q1、Q2、Q3、Q4均为预设数值,且0.8<Q1<Q2<Q3<Q4<1.2;;Preset platform inclination correction coefficient array Q0 (Q1, Q2, Q3, Q4), wherein, Q1, Q2, Q3, Q4 are all preset values, and 0.8<Q1<Q2<Q3<Q4<1.2;
根据中间点位置与各个预设中间点位置之间的大小关系,确定平台倾角修正系数,对平台倾角进行修正;According to the size relationship between the position of the intermediate point and each preset intermediate point position, the platform inclination correction coefficient is determined, and the platform inclination is corrected;
若A<A1,将第一预设平台倾角修正系数Q1作为平台倾角修正系数,修正后的平台倾角为α*Q1;If A<A1, the first preset platform inclination correction coefficient Q1 is used as the platform inclination correction coefficient, and the corrected platform inclination angle is α*Q1;
若A1≤A<A2,将第二预设平台倾角修正系数Q2作为平台倾角修正系数,修正后的平台倾角为α*Q2;If A1≤A<A2, the second preset platform inclination correction coefficient Q2 is used as the platform inclination correction coefficient, and the corrected platform inclination is α*Q2;
若A2≤A<A3,将第三预设平台倾角修正系数Q3作为平台倾角修正系数,修正后的平台倾角为α*Q3;If A2≤A<A3, the third preset platform inclination correction coefficient Q3 is used as the platform inclination correction coefficient, and the corrected platform inclination is α*Q3;
若A3≤A<A4,将第四预设平台倾角修正系数Q4作为平台倾角修正系数,修正后的平台倾角为α*Q4。If A3≦A<A4, the fourth preset platform inclination correction coefficient Q4 is used as the platform inclination correction coefficient, and the corrected platform inclination is α*Q4.
步骤S103,根据修正后的平台倾角选择对应的控制模式,以调整调平速度。Step S103, select the corresponding control mode according to the corrected platform inclination angle, so as to adjust the leveling speed.
为了缩短调平时间,本申请一些实施例中,根据修正后的平台倾角选择对应的控制模式,包括:若修正后的平台倾角大于倾角阈值,则选择第一控制模式控制调平速度;若修正后的平台倾角不大于倾角阈值,则选择第二控制模式。In order to shorten the leveling time, in some embodiments of the present application, the corresponding control mode is selected according to the corrected platform inclination, including: if the corrected platform inclination is greater than the inclination threshold, then select the first control mode to control the leveling speed; if the corrected If the subsequent platform inclination is not greater than the inclination threshold, the second control mode is selected.
本实施例中,平台倾角较大时,进行大幅度调平(第一控制模式),控制支腿运动速度较快,有利于减小调平时间。平台倾角较小时,进行小幅度调平(第二控制模式),控制支腿运动速度(调平速度)较慢,有利于减小过冲,提高调平精度。In this embodiment, when the inclination angle of the platform is large, large-scale leveling is performed (the first control mode), and the movement speed of the outriggers is controlled to be faster, which is beneficial to reduce the leveling time. When the inclination of the platform is small, perform small-scale leveling (the second control mode), and control the movement speed of the outriggers (leveling speed) to be slow, which is beneficial to reduce overshoot and improve leveling accuracy.
为了进一步缩短调平时间,本申请一些实施例中,所述第一控制模式包括:根据调整时间控制调平速度在第一区间,根据吊钩平台上物料重量对调平速度进行修正,得到修正后的调平速度区间值。In order to further shorten the leveling time, in some embodiments of the present application, the first control mode includes: controlling the leveling speed in the first interval according to the adjustment time, correcting the leveling speed according to the weight of the material on the hook platform, and obtaining the corrected The value of the leveling speed range.

为了提高调平准确性,本申请一些实施例中,在获取吊钩平台的多个支撑点位置之前,所述方法还包括检测方法,所述检测方法包括:获取伺服电机的输出转矩,对输出转矩进行滤波处理,得到滤波后的输出转矩,判断滤波后的输出转矩是否超过输出转矩阈值;若超过输出转矩阈值,则进行调平。In order to improve the leveling accuracy, in some embodiments of the present application, before obtaining the positions of multiple support points of the hook platform, the method further includes a detection method, and the detection method includes: obtaining the output torque of the servo motor, The output torque is filtered to obtain the filtered output torque, and it is judged whether the filtered output torque exceeds the output torque threshold; if it exceeds the output torque threshold, leveling is performed.
本申请一些实施例中,所述检测方法还包括:若滤波后的输出转矩未超过输出转矩阈值,则调整钢丝绳,钢丝绳调整后重新进行输出转矩检测。In some embodiments of the present application, the detection method further includes: if the filtered output torque does not exceed the output torque threshold, adjusting the steel wire rope, and re-testing the output torque after the steel wire rope is adjusted.
本实施例中,从支撑点的数量来区分,一个调平系统有几个支撑点就可以叫做几点调平系统,根据“三点确定一个平面”的原理,进行调平,当支撑点超过三个时,会出现虚腿现象,即存在一个支撑点肯能基本不受力。这在工程上是不允许的。这是因为当调平过程中出现虚腿时,如果出现外界干扰,平台会产生抖动,严重时甚至会造成倾覆,所以这种现象必须要加以避免。首先获取各个伺服电机的输出转矩,若转矩较小,说明钢丝绳不受力,处于悬空状态,需要先收紧钢丝绳,张紧后,进行调平,减小误差。In this embodiment, it can be distinguished from the number of support points. If a leveling system has several support points, it can be called a point leveling system. According to the principle of "three points determine a plane", leveling is performed. When the support points exceed Three times, there will be a phenomenon of empty legs, that is, there is a support point that can be basically unstressed. This is not allowed in engineering. This is because when there is a virtual leg during the leveling process, if there is external interference, the platform will vibrate, and even cause overturning in severe cases, so this phenomenon must be avoided. First obtain the output torque of each servo motor. If the torque is small, it means that the steel wire rope is under no force and is in a suspended state. It is necessary to tighten the steel wire rope first. After tensioning, perform leveling to reduce the error.

本实施例中,在调平的过程中,实时检测支撑点和中间点位置,若激光反馈偏差在合理范围内,停止调平,说明符合了调平要求。In this embodiment, during the leveling process, the positions of the support point and the middle point are detected in real time, and if the laser feedback deviation is within a reasonable range, the leveling is stopped, indicating that the leveling requirements are met.
