本发明属于铁路轨道装置技术领域，特别是一种适用于变轨距铁路货运列车的1435/1520mm轨距轨道过渡连接段及铺设方法。The invention belongs to the technical field of railway track devices, in particular to a 1435 / 1520mm gauge track transition connecting section and laying method suitable for variable gauge railway freight trains.
背景技术Background technique
目前，在世界范围内已经开展了多条铁路国际联运和区域运输通道，主要有欧亚大陆桥、泛欧铁路通道、泛亚铁路通道和北美铁路运输通道。但由于众多原因，上述通道沿线所经过的国家铁路具有多种不同的轨距，这给国际联运的发展带来了诸多不便。如欧亚大陆桥从我国上海、连云港出发到欧洲西海岸的阿姆斯特丹，铁路线总长1.1万km，分为北线、中线和南线。北线中的中国及欧洲各国都是窄轨(轨距为1435mm)，而蒙古国、俄罗斯、白俄罗斯均是宽轨(轨距为1520mm)。欧亚大陆桥的中线在我国境内是窄轨，沿着向西前行的中亚各国均为1520mm的宽轨。At present, there have been many international rail transport and regional transport corridors in the world, mainly including the Eurasian Continental Bridge, the Pan-European Railway Corridor, the Pan-Asian Railway Corridor, and the North American Railway Transportation Corridor. However, due to many reasons, the national railways passing along the above-mentioned passages have many different gauges, which brings a lot of inconvenience to the development of international intermodal transportation. For example, the Eurasian Continental Bridge departs from Shanghai and Lianyungang in China to Amsterdam on the west coast of Europe. The total length of the railway line is 11,000 km, which is divided into the north line, the center line and the south line. China and European countries in the northern line are narrow gauges (gauge is 1435mm), while Mongolia, Russia and Belarus are wide gauge (gauge is 1520mm). The central line of the Eurasian Continental Bridge is narrow-gauge in our country, and the countries of Central Asia traveling westward are 1520mm wide-gauge.
随着我国对外贸易交流的进一步加强和更为经济化发展，我国与周边各国之间通过铁路运输的商贸往来日益频繁，并在我国与邻国之间开展了多条铁路国际联运和区域联运通道。由于亚欧大陆桥成为其重要的铁路交通运输纽带，为沿路地区人民经济带来了福祉。然而，由于历史的原因，不同国家和地区的铁路采用了不同的轨距规格。在列车经过不同轨距规格的铁路时，宜采用变轨距转向架来提高运输效率。变轨距转向架的车轮在车轴轴向上可调节，从而实现变换转向架的轮对轮距以适应不同的轨距。目前，行业内为采用人力的方式实现轨距转换。具体地，通过支撑装置将变轨距转向架顶起，使车轮卸载，再通过人工将车轮安装至另一种规格。这种轨距转换方式效率低下，给开展国际联运带来了诸多限制。As China's foreign trade exchanges are further strengthened and more economically developed, trade transactions between China and neighboring countries through rail transportation are becoming more frequent, and multiple international and regional rail transportation channels have been launched between China and neighboring countries. . As the Asia-Europe Continental Bridge has become an important railway transportation link, it has brought benefits to the people's economy along the road. However, due to historical reasons, railways in different countries and regions have adopted different gauge specifications. When trains pass through railways with different gauges, variable gauge bogies should be used to improve transportation efficiency. The wheels of the variable-gauge bogie can be adjusted in the axial direction of the axle, so that the wheelset wheelbase of the bogie can be changed to adapt to different gauges. At present, in the industry, the conversion of gauges is implemented by means of manpower. Specifically, the variable-gauge bogie is lifted by the support device to unload the wheels, and then the wheels are manually installed to another specification. The low efficiency of this gauge conversion method has brought many restrictions to the development of international intermodal transportation.
近年来随着高速动车组转向架变轨距技术的进一步推进，公告号为CN 107574728 A的中国发明专利申请，公开了一种轨距转换装置，包括支撑轨、解锁轨和导向轨，支撑轨包括支撑预备轨和支撑持续轨，解锁轨包括解锁预备轨和解锁持续轨；支撑预备轨形成支撑段；支撑持续轨和解锁预备轨形成解锁段；支撑持续轨、解锁持续轨和导向轨形成导向段。该专利技术源于国外用于高速动车组的变轨距装置引进技术，适用于短编组的高速列车变轨运行，转向架进入地面轨距转换装置后，在支撑段，支撑预备轨将转向架的车轮承载模式，转换为轴箱或其他承载模式，使车轮卸载，此时列车轴箱位置处或转向架中部机构上将存在转移至车厢的全部载荷，对于重载的货运列车来说将严重威胁 列车行车安全、削弱转向架的寿命，为国际联运带来障碍。在解锁段，支撑持续轨持续保持轴箱支撑方式，车轮持续保持卸载状态；而解锁预备轨将解锁件逐步启动，直至达到解锁状态，此时车轮处于游离状态，即可轴向滑动。在导向段，支撑持续轨持续保持轴箱支撑方式，即车轮持续保持卸载状态；解锁持续轨持续保持解锁状态，即车轮处于游离状态；导向轨将车轮从一种轨距规格转换为另一种轨距规格，实现了轨距的转换。列车车辆在变轨过渡段变轨车辆处于滑移运行状态，对旁侧变轨轨道设施磨损巨大，对列车转向架轴箱及相关结构的磨耗较为严重，后期运营维护保养较为困难。与此同时需要对多有运行车辆配属统一的转向架变轨距机构，制造安装成本高昂，车辆轴重进一步加大。对于货运周转量巨大、贸易频繁的通道来说，该变轨装置不具有大范围适用意义。In recent years, with the further advancement of the gauge-changing technology of high-speed EMU bogies, the Chinese invention patent application with the announcement number CN107574728A has disclosed a gauge conversion device, including support rails, unlocking rails and guide rails, support rails Including support preparation rail and support continuous rail, unlocking rail includes unlock preparation rail and unlock continuous rail; support preparation rail forms support segment; support continuous rail and unlock preparation rail forms unlock segment; support continuous rail, unlock continuous rail and guide rail form guide segment. This patented technology originates from the introduction of foreign technology for variable gauge devices for high-speed EMUs. It is suitable for short-constant high-speed trains. The bogie enters the ground gauge conversion device. In the support section, the support rail prepares the bogie The wheel load mode is converted to the axle box or other load mode to unload the wheels. At this time, there will be full load transferred to the carriage at the position of the train's axle box or the middle of the bogie, which will be serious for heavy-load freight trains. Threats to train safety and weaken the life of bogies pose obstacles to international intermodal transportation. In the unlocking section, the support continuous rail continues to maintain the axle box support mode, and the wheels continue to maintain the unloaded state; while the unlock preparation rail gradually starts the unlocking piece until the unlocked state is reached, at this time, the wheel is in a free state, and can slide axially. In the guide section, the support continuous rail continues to maintain the axlebox support mode, that is, the wheels continue to remain unloaded; the unlock continuous rail continues to maintain the unlocked state, that is, the wheels are in a free state; the guide rail converts the wheels from one gauge specification to another The gauge specification realizes the conversion of gauge. Train vehicles are in slipping operation in the transition section of the track change, and the side track change track facilities are greatly worn, and the abrasion of the axle box and related structures of the train bogie is more serious, and later operation and maintenance are more difficult. At the same time, it is necessary to assign a unified bogie gauge mechanism to many running vehicles. The manufacturing and installation costs are high, and the axle load of the vehicle is further increased. For the passage with huge freight turnover and frequent trade, the orbit changing device does not have a wide range of application significance.
公告号为CN 107571685 A的中国发明专利申请，公开了一种列车车轮，确切地说是适应双轨距钢轨的列车车轮，是将列车车轮踏面设计为台阶式。提出了不同轨距钢轨直线对称无缝有高度差对接，宽轨距钢轨高出车轮两踏面圆半径差。当列车在标窄轨距钢轨行驶时，大圆踏面与钢轨接触。当列车在宽轨距钢轨行驶时，小圆踏面与钢轨接触，大圆踏面成轮缘，导向列车运行。此时在车轮设计制造中要求极高，适用性较差，涉及到轨距差较大的线路连接，为能连接过渡运行则要求所设计的车轮踏面较宽，在正常行走时将出现严重受力不均，横向振动及蛇形运动现象愈发突出。The Chinese invention patent application with the announcement number CN107571685A discloses a train wheel, specifically a train wheel adapted to double gauge rails, which is designed to have a stepped tread on the train wheel. It is proposed that the rails of different gauges are linearly symmetrical and seamless with height difference butt, and the wide gauge rails are higher than the radius difference of the two treads of the wheel. When the train is running on the standard narrow gauge steel rail, the large round tread is in contact with the steel rail. When the train is traveling on a wide gauge steel rail, the small round tread makes contact with the rail, and the large round tread forms the rim to guide the train to run. At this time, the requirements in the design and manufacture of wheels are extremely high, and the applicability is poor. It involves the connection of the line with a large gauge difference. In order to connect the transitional operation, the designed wheel tread is required to be wider. Uneven force, the phenomenon of lateral vibration and serpentine movement become more prominent.
