The invention discloses a deviation rectifying device of a truss type portal crane, which comprises a walking track, a portal crane cart, a position code and a controller, and the walking track comprises a first track and a second track which are parallel and spaced; the gantry crane cart comprises a first walking mechanism matched with the first track, a first power source used for driving the first walking mechanism, a second walking mechanism matched with the second track and a second power source used for driving the second walking mechanism. The first walking mechanism is provided with a first encoder and a first code scanner, and the second walking mechanism is provided with a second encoder and a second code scanner; the position codes are fixedly arranged relative to the walking track and comprise a first position code and a second position code which are arranged in parallel and at an interval, the first code scanner scans and identifies the first position code to determine the position of the first walking mechanism, and the second code scanner scans and identifies the second position code to determine the position of the second walking mechanism; the operation deviation of the door legs on the two sides can be detected, verified and corrected, so that wheels or steel rails are prevented from being damaged.

    本发明公开了一种桁架式门机的纠偏装置,包括行走轨道、门机大车、位置码和控制器,行走轨道包括平行且相间隔的第一轨道和第二轨道;门机大车包括配合于第一轨道的第一行走机构、用于驱动第一行走机构的第一动力源、配合于第二轨道的第二行走机构、用于驱动第二行走机构的第二动力源,第一行走机构设有第一编码器和第一扫码器、第二行走机构设有第二编码器和第二扫码器;位置码相对于行走轨道固定设置,位置码包括平行且间隔设置的第一位置码和第二位置码,第一扫码器扫描和识别第一位置码以确定第一行走机构的位置,第二扫码器扫描和识别第二位置码以确定第二行走机构的位置,能够检测、验证并更正两侧门腿的运行偏差,以避免损坏车轮或钢轨。
