The invention discloses a method for installing a positioning plate of a lifting appliance of a portal crane, and belongs to the technical field of lifting appliances. A front positioning plate and a rear positioning plate are arranged at the two ends of the upper surface of the lifting appliance; the scanning surface of the front scanner intersects with the rear positioning plate, the plate surface of the rear positioning plate inclines forwards, namely, the rear part is high and the front part is low, and the vertex of the rear positioning plate scanned by the front scanner is a detection point of the front scanner positioning plate; the scanning surface of the rear scanner is intersected with the front positioning plate, the plate surface of the front positioning plate is inclined backwards, namely, the front part is high and the rear part is low, and the vertex of the front positioning plate scanned by the rear scanner is a detection point of the rear scanner positioning plate. The positioning plate is used for solving the technical problems that in the prior art, a positioning plate has accumulated water, and positioning point detection reliability and shielding performance are not high.
本发明公布了一种门式起重机吊具定位板安装方法,属于吊具相关技术领域,吊具上表面的两端设置有前置定位板和后置定位板;前置扫描仪扫描面与后置定位板相交,后置定位板板面前倾,即后高前低,前置扫描仪扫描到的后置定位板的顶点为前置扫描仪定位板检测点;后置扫描仪扫描面与前置定位板相交,前置定位板板面后倾,即前高后低,后置扫描仪扫描到的所述前置定位板的顶点为后置扫描仪定位板检测点。本发明用于解决现有技术中的定位板有积水、定位点检测可靠性和遮挡性不强的技术问题。
