The invention relates to the technical field of railway wagon mechanical equipment, in particular to a pull rope type derailment automatic braking device. The pull rope type derailment automatic braking device comprises two derailment snapping devices which are symmetrically arranged and a three-way assembly, each derailment snapping device is connected to the three-way assembly through a connecting hose and connected with the three-way assembly through a derailment braking valve rod, and the three-way assembly is composed of a main pipe three-way part, a cut-off valve, a derailment vent valve and a hose three-way part. The left end of the hose tee joint is connected with the derailment vent valve, the other two ends of the hose tee joint are connected with the connecting hose, the other end of the derailment vent valve is connected with the cut-off valve, and the left end of the cut-off valve is connected with the main pipe tee joint; the device can rapidly trigger the derailment brake valve rod when the train derails, so that the train is braked emergently, accident loss is reduced, accident expansion is prevented, the structure is simple, fault points and the fault rate are reduced, and the safety of the train is improved.
本发明涉及铁路货车机械设备技术领域,尤其涉及一种拉绳式脱轨自动制动装置。该拉绳式脱轨自动制动装置,包括两个对称设置的脱轨拉断装置和三通总成,每个脱轨拉断装置通过连接软管连接到三通总成并通过脱轨制动阀杆连接,该三通总成由主管三通、截断阀门、脱轨放风阀和软管三通组成,软管三通左端连接脱轨放风阀,其余两端连接连接软管,脱轨放风阀另一端连接截断阀门,截断阀门左端连接主管三通,脱轨拉断装置包括两个弹性销、顶梁和U形钢丝缆绳,钢丝缆绳两端连接顶梁两端,该装置在车辆脱轨时能迅速触发脱轨制动阀杆,使列车紧急制动,减少事故损失并防止事故扩大,其结构简单减少了故障点和故障率,提高了列车安全性。
