The invention discloses a fine adjustment method for a portal crane, which belongs to the technical field of hoisting engineering, and comprises the following steps: a, arranging a moving platform on a trolley frame in the X direction, arranging a transporter at the bottom of the moving platform, arranging a square steel rail for the transporter to slide on the upper part of the trolley frame, arranging the square steel rail along the direction of a cart traveling mechanism, a transverse pushing hydraulic oil cylinder is arranged between the movable platform and the trolley frame; b, in the Y direction, two wheels driven by a motor are arranged on the trolley walking mechanism, then two micro-motion walking wheels are arranged, and the micro-motion walking wheels are driven by a servo motor; and c, in the Z direction, a balance pulley is arranged on the movable platform and is driven by a vertical pushing oil cylinder, and the vertical pushing oil cylinder drives the balance pulley to ascend or descend. High-precision micro-motion control can be carried out in the X direction, the Y direction and the Z direction, and the requirement for accurate positioning is met.
本发明公开了一种门式起重机微动调整方法,属于吊装工程技术领域,包括以下步骤:a、X方向,在小车架上布置移动平台,在移动平台底部装设移运器,小车架上部设置用于移运器滑动的方钢轨道,方钢轨道沿着大车行走机构方向布置,在移动平台和小车架之间设置横推液压油缸;b、Y方向,在小车行走机构上设置两个通过电机驱动的车轮,再设置两个微动行走车轮,微动行走车轮通过伺服电机驱动;c、Z方向,将平衡滑轮装设于移动平台上,平衡滑轮通过竖推油缸驱动,竖推油缸驱动平衡滑轮作上升或下降运动。本发明能够在X、Y和Z三个方向进行高精度微动控制,达到精确定位要求。
