Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in the attached drawings, the under-cover unloading system of the subway vehicle section comprises an unloading field 5 and a bridge crane 4 arranged above the unloading field 5; the unloading site 5 comprises a parking space 501 and an unloading line 502 which are sequentially arranged along the span direction L of the bridge crane 4; also includes a support structure; the support structures are provided with a plurality of groups, and the support structures are arranged in pairs at intervals along the length direction of the unloading field 5; the support structure comprises a first upright 2 and a second upright 3 arranged in pairs; unloading place 5 is located between first stand 2 and the second stand 3, just bridge crane 4 passes through first stand 2 and the installation of second stand 3 are supported.
The first upright 2 and the second upright 3 are used as a support system of the upper cover 1 and a support system of the bridge crane 4. And the unloading site 5 is not provided with other supporting systems of the upper cover 1. The upper cover 1, the bridge crane 4 and the unloading site 5 are sequentially arranged at intervals from top to bottom, the distance between the upper cover 1 and the bridge crane 4 can meet the requirements of the installation and the running height of the bridge crane 4, and the distance between the bridge crane 4 and the unloading site 5 can meet the requirements of the unloading height.
