November twenty eighth
Developed by China Railway Science and EngineeringThe world's first kiloton multi-mode new energy bridge erecting machine“Ying Long”Jiangji Section of Zhuhai-Zhaoqing High-speed Railway in GuangdongJJZQ-Bid 8Completed successfully“First show”
According to《The Classic of Mountains and Rivers》Record，Ying Long，Be called by the honorific“God of creation”And“Creator God”，In charge of the four seasons、Mountains and rivers，Help the Yellow Emperor conquer Chiyou、Dayu controls the flood，It is the embodiment of wisdom and courage.。
Slowly“Stretch your legs”
Steadily“Lift the beam onto the bridge”In a flexible manner“Move and convert”……This set“Kung Fu skill”There are three exclusive magic weapons hidden behind it.？！And that is“Metamorphosis Avatar”“Mechanical brain”And“Green Heart”
01
“Metamorphosis Avatar”
Most of the Zhuzhao high-speed rail are continuous ultra-low portal piers.，It is also adjacent to the Guangzhou-Zhanjiang Railway，The distance between pier lines is small，There are different line height difference，The working condition of the whole line is extremely complex.。How to Achieve Uninterrupted and Continuous Over-Low Pier，And can be constructed under the construction conditions of limited height and limited width，Complete the erection of box girder at one go？The technical team of China Railway Science and Engineering Machinery Institute combines many years of research and development experience of non-standard customized special engineering equipment.，Innovative design of a new mode of construction method。
In the design deduction，Machinery added and removed from the drawings“Outrigger”Assembly and disassembly of modular components，Let the technical team instantly associate with being able to assemble freely.、Flexible and changeable“ Transformers ”，Disassemble all parts of the bridge erecting machine into“Module group”，Modular derivative design is realized on the basis of traditional single-girder bridge erecting machine.，That is to say, special single-track middle leg is set for special working conditions.，Cooperate with ultra-low conversion support，At the same time, the new erection scheme of double-span erection is adopted.。
The technical team has also developed a 1000-ton four-car hydraulic drive modular beam carrier for the bridge erecting machine.，Capable of being assembled“ Transformation ”Multiple modes，Realization sheet、Quick Conversion of Double-track Box Girder Transportation，Equipped with automatic assistant driving system and synchronous control technology，It is safer to transport beams through the tunnel、Efficient。
02
“Mechanical brain”
Possess“Mechanical brain”，Talent“ Think twice before you do ”。The technical team independently developed a set of environmental awareness.、Attitude detection、Pressure sensing、Intelligent anti-overturn、Intelligent safety management system integrating six key systems such as image recognition and automatic alarm，And realize that intelligent operation of the bridge erecting machine.。
In addition，Developed“One key via”“Erect the beam with one key”System，So that that novel bridge erec machine can be monitored in real time、Collect key process safety data，Built-in automatic control logic program，You can judge the security status by yourself.，The automatic start-stop positioning accuracy can reach millimeter level.。Device Management Cloud Platform，Let a mobile phone、A computer can grasp the data of the bridge erecting machine thousands of miles away.，Targeted operation and maintenance management。
03
“Green Heart”
“We are continuing to explore the installation of a special construction machinery and equipment.‘Green Heart’，Realizing traditional railway carrying, transporting, erecting and laying equipment，Intelligent industrial chain、Greening。”The technical team said。 Aim at that bridge erecting machine，The technical team proposed“Range extender+Power Battery”Power source system and its control strategy，It is the first time to apply new energy technology to it.，Its fuel consumption can be saved by 40%。
The first domestic electric drive 1000-ton box girder rubber-tyred carrier was successfully hoisted in Xiongshang high-speed rail.，The kiloton electric drive beam carrier has been efficiently applied to many high-speed rail beam factories in China.，And then to“Penglai”Intelligent track-laying unit is famous overseas，China Railway Industry has always focused on R & D, manufacturing, energy saving and carbon reduction.，Make every effort to promote equipment renewal、Digital intelligence transformation、Green and low-carbon transformation，Forging the Heavy Weapons of Great Powers in the New Era。
Zhuzhao high-speed rail is the first high-speed rail with a speed of 350 kilometers per hour independently invested and managed by Guangdong Province.，It is also a synergy between the two sides of the Pearl River.、It is an important strategic high-speed rail for high-quality development.。After the completion of the project，It will connect Jiangmen Station and the Pearl River Delta Hub Airport in series.，Seamless connection between orbit and aviation，The major cities in the Pearl River Delta along the line will be accessible in one hour.。
The more difficult it is，The more you want to solve the problem
Let Intelligent Equipment Help Human Beings Travel Better
