[0002] When constructing a subway station under a 500kV high-voltage line, a gantry crane is required. This type of gantry crane is a double-girder gantry crane. A double-girder gantry crane is a common crane equipment used for loading and unloading operations in outdoor freight yards, material yards, and bulk cargo.

[0003] In the existing technology, after the legs of the gantry crane for subway station construction under the 500kV high-voltage line are installed above the traveling trolley, horizontal No. 10 channel steels need to be welded between the legs to maintain the spacing between the legs. Since the channel steels are fixedly welded, it is inconvenient to assemble and disassemble the legs, and it is difficult to achieve the effect of rapid installation and disassembly of the gantry crane in a confined space. Secondly, since the legs of the gantry crane are mostly inclined, most of them only use simple connecting parts to connect the bottom of the legs to the traveling trolley. The simple connecting parts have poor supporting effect on the legs and are easy to affect the main beam at the top of the legs. Utility Model Content

Secondly, the simple connecting parts have a poor supporting effect on the support legs, which is easy to affect the main beam on the top of the support legs.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
