The invention relates to a wire drawing device for measuring an included angle between a trailer head and a container and a measuring method thereof. The wire drawing device comprises a trailer head traction base, a first wire drawing motor, a second wire drawing motor, a container fixing base, a girder, container connecting supports and a controller. The first wire drawing motor and the second wire drawing motor are symmetrically mounted at the tail part of the trailer head traction base left and right; the container fixing base and the front center of the girder are connected with the axis of the traction base; the container connecting supports are symmetrically placed, and the upper parts thereof are connected with the container fixing base and the rear part of the girder; wire drawing points are symmetrically arranged at the lower parts of the two container connecting supports and are connected with pull wires extending out of the first wire drawing motor and the second wire drawing motor respectively; and pull wire length sensors on the first wire drawing motor and the second wire drawing motor measure and transmit the pull wire length variation of the corresponding wire drawing motors to the controller, and the controller calculates the included angle between the trailer head and the container according to the geometrical relationship. The horizontal included angle between the trailer head and the container can be measured independently, and the pitching angle interference of the container can be avoided.
本发明涉及一种测量挂车车头与货箱夹角的拉线装置及其测量方法,拉线装置包括车头牵引座、第一拉线电机、第二拉线电机、货箱固定座及大梁、货箱连接支架、控制器;第一拉线电机和第二拉线电机左右对称安装在车头牵引座尾部;货箱固定座及大梁前部中心与牵引座轴心相连接;两个货箱连接支架对称布置,其上方与货箱固定座及大梁后部相连接;两个货箱连接支架下部对称设有拉线点,与第一拉线电机和第二拉线电机伸出的拉线分别连接;第一拉线电机和第二拉线电机上拉线长度传感器测量并向控制器传输相应拉线电机的拉线长度变化量,控制器根据几何关系计算挂车车头与货箱的夹角。本发明可以单独测量挂车车头与货箱的水平夹角且可避免货箱俯仰角度干扰。
