Embodiment Construction

[0036] as attached Figure 4 As shown, the sound insulation and noise reduction device for locomotive doors and windows provided by the embodiment includes two layers of glass 3,6 and a window frame 5 for fixing the glass 3,6, inner and outer layer window frames 4,7, window frame 5 and window frame 4 , 7 are thin metal plates formed by cold pressing through molds; the two layers of glass 3, 6 are not installed in parallel, and the glass 3 on the side of the noise source is installed at an inclination angle of 5° to the vertical direction. When assembling the welding device, fill the non-installed glass area with sound-absorbing materials; use rubber bead 1 and bead core 2 to fix the glass 3 and 6 on the inner window frame 4 and outer window frame 7 respectively, and the interface of the rubber bead 1 needs to be Cut neatly and stick together tightly with glue. Moreover, the section of the rubber bead 1 and the bead core 2 that seals between the window frames 4, 7 and the glas...

Abstract

The invention discloses a sound-insulating and noise-reducing device for locomotive doors and windows, comprising two layers of glass and window frames fixing the glass. The device is characterized in that the two layers of glass are not mounted in parallel, the glass near the noise source side is mounted in an inclined way with 2-10 degrees to the vertical direction, and the glass far from the noise source is mounted perpendicular to the horizontal direction. The device can improve the sound-insulating and noise-reducing ability of a locomotive noise source machine room door, thus further reducing the noise value of the locomotive cab and meeting requirement that the comfort level of driver and passenger is increasingly improved.

Description

technical field [0001] The invention relates to a sound insulation and noise reduction device, in particular to a sound insulation and noise reduction device for locomotive doors and windows. Background technique [0002] Existing technology as attached figure 1 , the traditional sound insulation device for locomotive door and window glass is composed of two pieces of glass with the same thickness of 3~6mm inside and outside, and a window frame and window frame between the two layers of glass, and the two pieces of inside and outside glass are installed parallel to each other, the inside and outside glass and the window The air enclosed between the poles forms a columnar body. This kind of locomotive door and window glass sound insulation device has achieved a certain sound insulation effect, but there are still certain problems, as follows: [0003] 1) The thickness of the two pieces of glass inside and outside is the same, which is prone to the effect of glass anastomosi...
