Abstract

The invention discloses an expandable gantry crane frame. The expandable gantry crane frame comprises a main beam, wherein a pair of vertical pillars are arranged on two sides of the main beam respectively, a main lifting device is arranged at the lower end of the main beam, and a driving end of the main lifting device is fixedly connected with the upper ends of the vertical pillars; main supportsare arranged at the lower ends of the vertical pillars, and auxiliary supports are hinged and mounted on the outer sides of the main supports; connecting rods are hinged and mounted between the auxiliary supports and the vertical pillars, and auxiliary support resetting devices are arranged in the connecting rods. The mobile distance of a second mobile seat can be extended by use of extending auxiliary beams. According to the device, the support stability of the lower ends of the vertical pillars can be increased through the auxiliary supports, and during transportation, and space occupationof the auxiliary supports can be saved through folding. The device also can transport articles outside the device by use of a second lifting hook through matching of an auxiliary guide rail driving motor and a third mobile seat, so that the article transportation demand is better met, and the trouble of manual carrying is avoided.

Description

technical field [0001] The invention relates to the technical field of gantry hanger design, in particular to an expandable gantry hanger. Background technique [0002] Large-scale goods are generally transported directly by hangers during short-distance transport. For goods with low transport heights and relatively fixed working positions, gantry cranes are generally used for transport. The existing gantry cranes make it difficult to directly transport goods due to their own structural limitations. To the outside of the gantry frame, manpower is still required for partial handling operations, and because the existing gantry crane frame is directly supported by vertical columns, the stability is not good. If a new type of gantry hanger with a more stable frame and less limited handling position can be designed to solve such problems, we provide an expandable gantry hanger for this purpose. Contents of the invention [0003] The purpose of the present invention is to provi...
