Abstract

The invention provides an aluminum alloy subway A-type vehicle side wall first-position side and second-position side reverse assembly device. The device comprises a cross beam assembly, two edge beam positioning and pressing assemblies, a plurality of formwork assemblies, a door jacking and pressing device, a doorway unit pressing device, a wallboard positioning block and a reversible deformation device are installed on the cross beam assembly, and the reversible deformation device can be installed through the cross beam assembly; the edge beam positioning and pressing assemblies are used for prefabricating deflection of a side wall and pressing an edge beam on the side wall; the formwork assemblies are used for fixing a side wall profile and guaranteeing the profile tolerance requirement of the side wall; the door jacking and pressing device is of a turnover structure and is used for jacking and pressing a side wall doorway profile when a first-position side wall and a second-position side wall are switched. the doorway unit pressing device is used for guaranteeing the overall profile tolerance of the side wall; and the wallboard positioning block is used for guaranteeing the width from the side wall to a doorway. The device can be suitable for reverse assembly of the first-position side wall and the second-position side wall at the same time, the site and tool cost is saved, the multi-project switching function can be achieved by replacing nylon blocks, the operation is convenient and fast, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of subway construction tooling, and more specifically relates to an aluminum alloy subway A-type car side wall one- and two-position side reverse assembly device. Background technique [0002] At present, the side walls of the aluminum alloy subway A-type vehicles on the market are mostly assembled and welded on the first and second sides. Because the subway side walls are divided into one and two sides, the side walls on the first and second sides need to be assembled and welded separately. Therefore, two sets of tooling are required, which not only has high requirements on the number of tooling and the site, but also occupies too large an area, and cannot meet the requirements of parallel construction of two projects on the same site and at the same time. Contents of the invention [0003] The purpose of the present invention is to provide an aluminum alloy subway A-type car side wall one- and two-positi...
