Abstract

The pre-distribution assembly method for slot of underground vehicle comprises: first, finishing the slot pre-distribution on platform based on supporting frame by assembling all cables and accessories into slots according to design request; then, conveying said pre-distribution slots to two sides of vehicle with a hydraulic lifting movable carriage for underframe slot assembly. The advantages of this invention include: not high investment for field and device in infrastructure, about 9-10h to complete the assembly and continuing some work for assembling underframe slot compared with about 12h overseas and stopping other operation; reducing assembly difficulty greatly, and improving work environment.

Description

technical field [0001] The invention relates to a method for pre-laying and installing wire grooves of subway vehicles, which belongs to the category of vehicle assembly methods. Background technique [0002] Generally, the wiring of subway vehicles adopts the installation method of trunking. At present, the relatively well-known subway car manufacturers in the world, such as Germany's Siemens, must first use moving platforms, rail cars, and mobile racking machines and pre-laying installations when installing subway car trunking. Workbench, for this reason, the ground track for the transitional cooperation between the rail car and the moving car platform should be built on the ground of the wire slot installation platform; The pre-fabricating workbench is hoisted to the rail car by the crane, and then transferred to the bottom of the car body of the special installation platform through the moving car platform; during installation, it is necessary to adjust the left and rig...
