The invention provides an electric passenger car anti-derailment emergency brake device, and relates to the technical field of braking, the electric passenger car anti-derailment emergency brake device comprises a top plate, the lower side of the top plate is fixedly provided with a connecting seat, the front side of the connecting seat is fixedly provided with a linear array camera, and the two sides of the connecting seat each comprise an extending arm structure; an air storage tank located on the rear side of the connecting base is fixed to the lower side face of the top plate, and the sides, away from the connecting base, of the two extending arm structures are in a splayed shape and incline forwards and downwards. The connected sliding arm drives the storage box and the connecting base to get close to the wheel through the extending arm structure, gas in the gas storage tank conveniently pushes the brake pad to get close to the wheel after the electromagnetic valve is opened, the brake pad is further pressed to the wheel through expansion of the high-expansion alloy ball in the friction period of the brake pad and the wheel, and the brake pad is prevented from being damaged. The carbonyl iron powder carried by the gas is in friction fit between the two grinding wheel pieces and the rail and between the wheel section of the brake wheel and the rail, the wheel section of the brake wheel extends into the inner side of the rail, and the braking and derailing prevention effects are achieved.
本发明提供一种电客车防脱轨紧急刹车装置,涉及刹车技术领域,其包括顶板,所述顶板的下侧固定有连接座,所述连接座的前侧固定安装有线阵相机,所述连接座的两侧均包括有伸臂结构,所述顶板的下侧面固定有位于连接座后侧的储气罐,两个所述伸臂结构远离连接座的一侧呈外八字并向前倾斜向下。通过伸臂结构使连接的滑动臂带动存储箱和连接座靠向车轮,方便电磁阀打开后,储气罐内的气体推动刹片靠向车轮,在刹片与车轮摩擦的期间经过高膨胀合金球的膨胀,使得刹片进一步压向车轮,而被气体携带的羰基铁粉在两个砂轮片以及刹轮的轮段与铁轨之间摩擦配合刹轮的轮段伸入铁轨的内侧,起到制动和防脱轨的作用。
