The invention relates to a gantry crane with an over-deviation detection structure. A cross beam, an alarm device, a detector, a sling, a lifting seat, a lifting seat driving mechanism, a sling lifting mechanism, a rigid circular ring and a soft circular ring groove are included, wherein the lifting seat is connected to the cross beam in a sliding manner; the lifting seat driving mechanism is used for driving the lifting seat to move on the cross beam; the sling lifting mechanism is arranged on the lifting seat and is used for collecting the sling; the rigid circular ring sleeves the sling, and the soft circular ring groove is located in the rigid circular ring and extends in the circumferential direction of the rigid circular ring. The rigid circular ring and the soft circular ring groove are connected together in a sealed mode to form an annular liquid storage cavity, the liquid storage cavity is filled with liquid, the axis of the soft circular ring groove is located on the sling when the sling is in a vertical state, the sling is extruded to the soft circular ring groove when the inclination angle of the sling is larger than a set value, and the alarm device gives an alarm when the detector detects that the sling is extruded to the soft circular ring groove. The gantry crane has the advantage that the inclination angle of the sling can be known when being larger than the set value, and the problem that the inclination angle of a sling of an existing hoisting mechanism for assembling and disassembling a concrete mold is not known when not meeting the requirement is solved.

    本发明涉及一种设过偏检测结构的龙门吊,包括横梁、报警器、检测器、吊索、滑动连接在横梁上的吊座、驱动吊座在横梁上移动的吊座驱动机构、设置在吊座上的收起吊索的吊索提升机构、套设在吊索上的刚性圆环和位于刚性圆环内部的沿刚性圆环周向延伸的软性圆环槽,刚性圆环和软性圆环槽密封连接在一起围成环形储液腔,储液腔内储满液体,吊索处于竖直状态时软性圆环槽的轴线位于吊索上,吊索的倾斜角度大于设定值时吊索挤压到软性圆环槽,检测器检测到吊索挤压到软性圆环槽时报警器报警。本发明具有吊索的倾斜角度大于设定值时能够知道的优点,解决了现有的混凝土模具装拆用吊装机构的吊索倾斜角度不符合要求时不知道的问题。
