The invention discloses a hoist crane trolley running limiting system and method, a first reflector and a second reflector are respectively arranged at two ends of a hoist crane beam, and a first infrared distance measuring device is used for monitoring a first distance between a hoist crane trolley and the first reflector in real time; the second distance between the hoist trolley and the second reflector is monitored in real time through the second infrared distance measuring device, and the hoist trolley can be controlled to stop moving when the first distance or the second distance is smaller than a threshold value, so that rigid collision between the hoist trolley and the two ends of the hoist trolley is avoided, and the service life of the hoist trolley is prolonged. And the body of the hoist trolley is prevented from being damaged, derailed and falling.
本发明公开了一种葫芦吊小车走行限位系统及方法,在葫芦吊车梁的两端分别设置了第一反光板和第二反光板,并通过第一红外测距装置实时监测葫芦吊小车与第一反光板之间的第一距离,通过第二红外测距装置实时监测葫芦吊小车与第二反光板之间的第二距离,可以在第一距离或第二距离小于阈值时,控制葫芦吊小车停止移动,从而避免葫芦吊小车与葫芦吊小车的两端发生刚性碰撞,使葫芦吊小车的车体不会受损和脱轨坠落。
