A df4 type locomotive side wall single-layer glass installation and fixing device

Abstract

The invention relates to a mounting and fixing device for a single layer of glass of a DF4 locomotive side wall, and belongs to the technical field of machine manufacturing and mounting. The mounting and fixing device comprises an outer side pressing frame and an inner side pressing frame, and the outer side pressing frame and the inner side pressing frame are two symmetrical arc-shaped structures. The outer side pressing frame is provided with a convex pillar, the inner side pressing frame is provided with a concave groove, and the concave groove and the convex pillar are connected in a buckled mode. According to the mounting and fixing device, the inner side pressing frame and the outer side pressing frame which are made of aluminum alloy are used for fixing the locomotive side wall glass, corrosion damage to the pressing frames by the external environment can be effectively prevented, the service life of the pressing frames is prolonged, and maintenance cost and environmental pollution are lowered. The inner side pressing frame and the outer side pressing frame are provided with the buckled structures, so that the firmness is enhanced, dismounting is easy, maintenance is convenient, recycling can be achieved, the glass can be mounted more firmly, and shock resistance is good. The mounting and fixing device for the single layer of glass of the DF4 locomotive side wall is economical and practical, easy to operate, capable of saving energy, environmentally friendly, and high in firmness and shock resistance.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and installation, in particular to the technical field of locomotive glass installation and fixing, in particular to a DF4 type locomotive side wall single-layer glass installation and fixing device. Background technique [0002] DF4 locomotives are mainly divided into DF4B, DF4C, and DF4D diesel locomotives. The side windows on the side walls of DF4 locomotives are all made of rubber bead (DL14002-87) to fix the single-layer tempered glass on the side wall panels, such as figure 1 , 2 shown. The rubber bead is a rubber part. The rubber bead on the outside of the tempered glass has been exposed to the outdoors for many years. After being affected by wind, sun, rain and external environmental temperature changes, it is prone to aging, cracking, loosening and other problems, which will affect the firmness of the tempered glass. , in order to prevent safety problems caused by the ...
