The invention belongs to the technical field of loudspeaking warning devices, and particularly relates to a railway locomotive and rail car environment-friendly whistle-limiting warning device which comprises a host control box, a wiring terminal is arranged on one side of the host control box, and an electromagnetic shielding layer is fixedly installed on the inner surface of the host control box. Positioning assemblies for extruding a cable connected to the wiring terminal are arranged on the host control box on the two sides of the wiring terminal; the positioning assembly comprises transverse plates, the transverse plates are fixedly installed on the host control box on the two sides of the wiring terminal, a plurality of electric push rods are fixedly installed at the opposite ends of the two transverse plates, and push rods of the electric push rods penetrate through the transverse plates to be fixedly provided with extrusion plates. The GJLY-1 locomotive loudspeaking warning indicator is high in integration, convenient to install and use and stable and reliable in work during operation, and interference of external electromagnetism on the GJLY-1 locomotive loudspeaking warning indicator can be avoided through the electromagnetic shielding layer and the positioning assembly.

    本发明公开的属于扬声警示器技术领域,具体为铁路机车和轨道车环保限鸣警示装置,包括主机控制盒,所述主机控制盒的一侧设有接线端子,所述主机控制盒的内表面固定安装有电磁屏蔽层,位于接线端子两侧的所述主机控制盒上设有用于对连接在接线端子上的线缆进行挤压的定位组件;所述定位组件包括横板,位于接线端子两侧的所述主机控制盒上固定安装横板,两组所述横板的相背端均固定安装若干电动推杆,所述电动推杆的推杆穿过横板固定安装挤压板。本发明的GJLY‑1机车扬声警示器不仅集成化高,安装使用方便,而且在运行时,工作稳定可靠,会通过电磁屏蔽层和定位组件避免外界电磁对GJLY‑1机车扬声警示器造成干扰。
