针对铁塔检修工人高空作业时手动挂拆安全绳危险性高和效率低的问题,基于菱形原理设计了一种V型角钢对称夹持机构,主要由夹持爪、外展机构和顶出机构组成,夹持爪通过螺旋升降机与滑动导轨的配合实现对角钢的抓紧,垂直于夹持手臂的外展机构通过调整其展出距离改变夹持爪的位置,顶出机构前端的V型块设计可保证机器人机身始终平行于角钢。绘制机器人的SolidWorks三维模型,依据菱形原理简化模型,并验证其对中夹持性和机构设计的合理性,建立静力学模型,对夹持机构进行静力学分析和静力学仿真。通过样机试验,验证了该夹持机构的可行性。
In view of the high risk and low efficiency of the manual maintenance of the safety rope during the work of the tower, the V-shaped angle steel symmetrical clamping mechanism is designed based on the principle of rhombus principle. It is mainly composed of a gripping hand, an abduction mechanism and an ejection mechanism. The clamping hand realizes the grasping of the diagonal steel by the cooperation of the screw jack and the sliding rail, and the abduction mechanism perpendicular to the clamping arm changes the position of the gripping hand by adjusting the exhibition distance thereof, and the V-shaped block on the front end of the ejector mechanism ensures that the robot body is always parallel to the angle. According to the analysis of the climbing environment of the transmission tower climbing robot, the three-dimensional model of the mechanism is drawn. The model is simplified according to the principle of rhombus principle and the rationality of the centering and the size of the mechanism is verified. The statics model is established and the clamping force is used for mechanical analysis and structural statics simulation. Through the prototype development and test, the feasibility of the clamping mechanism is preliminarily verified.
