The rail-mounted gantry crane portal frame comprises a girder, a lower cross beam, a rigid supporting leg and a flexible supporting leg, the girder and the lower cross beam are connected with the rigid supporting leg and the flexible supporting leg on the upper side and the lower side respectively, the flexible supporting leg is connected with the first end of the girder through a flexible hinge, the rigid supporting leg is fixedly connected with the second end of the girder, and the rigid supporting leg is of a hollow structure and comprises a kidney-shaped section; the flexible supporting leg is of a hollow circular tube structure. The portal frame of the rail-mounted gantry crane adopts a structure in which the steel leg and the flexible leg are matched, the flexible leg adopts a hollow circular tube structure, and the steel leg adopts a waist-shaped section design, so that the wind resistance can be effectively reduced, and the aim of light weight is fulfilled. The invention further provides a high-speed automatic rail-mounted gantry crane.
提供一种轨道吊龙门架,包括大梁、下横梁、刚性支腿和柔性支腿,大梁和下横梁分别在上侧和下侧连接刚性支腿和柔性支腿,柔性支腿和大梁的第一端通过柔性铰连接,刚性支腿和大梁的第二端固定连接,刚性支腿为空心结构,包括腰型截面;柔性支腿为空心圆管结构。上述轨道吊龙门架采用钢腿、柔腿配合的结构,其中柔腿采用空心圆管结构,刚腿采用采用腰形截面设计,能够有效降低风阻并实现轻量化的目的。还提供一种高速自动化轨道吊。
