本发明涉及铁路列车故障处理设备技术领域，尤其涉及一种铁路道岔打磨车应急起复装置及其使用方法。The invention relates to the technical field of railway train fault handling equipment, in particular to an emergency recovery device for a railway turnout grinding car and a method for using the same.
背景技术Background technique
道岔区作为铁路线路重要组成部分，相较于区间线路，道岔区轨道结构复杂，钢轨磨耗速率快，导致病害频发，日常轨道养护工作中需要利用道岔打磨车对道岔区钢轨进行打磨作业，消除钢轨病害，维护道岔正常服役状态。The turnout area is an important part of the railway line. Compared with the interval line, the turnout area has a complex track structure and a fast rail wear rate, which leads to frequent diseases. In the daily track maintenance work, it is necessary to use a turnout grinding car to grind the rails in the turnout area to eliminate Rail disease, maintain the normal service state of the switch.
在打磨作业过程中，打磨车通过液压压力将砂轮压在钢轨上对钢轨进行磨削，达到维护钢轨廓形的目的，此时，在打磨车与钢轨之间形成相互作用力，即打磨车受到钢轨反力，加之道岔打磨车轴重相比铁路普通车辆轻，这些因素导致道岔打磨车在施工作业中存在极大的脱轨掉道风险，特别是在新建线路打磨作业时，由于线路轨道几何尺寸尚未稳定，掉道事故时有发生。During the grinding operation, the grinding car presses the grinding wheel on the rail to grind the rail through hydraulic pressure to achieve the purpose of maintaining the profile of the rail. At this time, an interaction force is formed between the grinding car and the rail, that is, the grinding car is subjected to The reaction force of the rails, coupled with the lighter axle weight of the turnout grinding car than that of ordinary railway vehicles, these factors lead to a great risk of derailment and falling off the track in the construction operation of the turnout grinding car, especially in the grinding operation of the new line, because the geometric size of the line track has not been Stable, but accidents do occur from time to time.
铁路道岔打磨现场作业中，遇到车辆在道岔区脱轨时，由于道岔打磨车车底空间狭小，大型应急设备存在无空间、无位置摆放和安装等情况，并且打磨车后转向架构造特殊，无合适的设备起复支撑点，导致普通起复设备无法实现道岔打磨车后转向架的起复，此外，车辆在脱轨后会发生偏斜，假如偏斜量过大，普通起复设备对车辆的校正困难较大。During the on-site operation of railway turnout grinding, when the vehicle derails in the turnout area, due to the narrow space at the bottom of the turnout grinding car, there is no space, no location for placement and installation of large emergency equipment, and the structure of the bogie behind the grinding car is special. There is no suitable lifting support point for the equipment, so that the ordinary lifting equipment cannot realize the lifting and recovery of the bogie after the turnout grinding car. In addition, the vehicle will deflect after derailment. If the deflection is too large, it is more difficult for the ordinary lifting equipment to correct the vehicle. big.
综上所述，现有的铁路车辆起复设备和技术，在应急抢险中所需设备配件数量多、重量大，造成起复救援工作效率低，同时安全风险大且易造成二次事故。因此，研发与铁路线路作业环境匹配度高，便于组装和操作的可携带式应急救援装置，对掌握现场科学应急方法，提升铁路车辆非正常应急处置能力具有重要现实意义。To sum up, the existing railway vehicle recovery equipment and technology requires a large number of equipment accessories and heavy weight in emergency rescue, resulting in low recovery and rescue work efficiency, and at the same time, high safety risks and easy to cause secondary accidents. Therefore, it is of great practical significance to develop a portable emergency rescue device that is highly compatible with the railway line operating environment and is easy to assemble and operate.
