The invention discloses an obstacle and derailment monitoring device for railway vehicles. The obstacle and derailment monitoring device for railway vehicles comprises a mounting seat, a support arranged on the mounting seat, a plate spring and a collision crossbeam. An obstacle trigger and a derailment trigger are arranged on the support, and a first limit part and a second limit part which are parallel to each other are arranged on the support. The plate spring comprises a body, a first bent portion and a second bent portion, wherein the first bent portion is formed at one end of the body, the second bent portion is formed at the other end of the body, the body overlaps the first limit part, the front side face of the first bent portion butts against the second limit part, the back sideface of the first bent portion butts against the first limit part, and the second bent portion is connected with the support. The collision crossbeam is connected with the lower end of the first bentportion. The obstacle and derailment monitoring device for railway vehicles has the advantages that the possibility of false warning is eliminated, the fatigue strength of a suspension point of the collision crossbeam is improved, and the limit parts cannot affect displacement of the detection crossbeam to trigger warning under the condition of obstacle collision and derailment.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an obstacle and derailment monitoring device for rail vehicles. Background technique [0002] In the related art, the leaf springs of the obstacle and derailment monitoring device, such as n-shaped leaf springs, are constrained at one point, and the leaf springs are in an unconstrained free state. When the vibration occurs during the running of the vehicle, the detection beam is in a relative vibration state with the fixed point of the mounting seat, and cannot be firmly limited to the constraint point. When the vibration amplitude of the detection beam relative to the fixed point of the mounting seat reaches the trigger displacement, A false alarm will be triggered. [0003] For example, the Chinese patent application with publication number CN106163900A discloses a monitoring device for obstacles and / or derailment of railway vehicles, comprising: beams designed to receiv...
