For the first time in China!"Xiangyang made" a thousand -ton bridge machine successfully turned around self -round

"Rotate 4.5 degrees, various reports are normal; 180 degrees transfer, and turn the task to complete."

At 20:30 on June 17th, at the Hangzhou -Chan Railway 2 standard site, the "Kunlun" of the "Xiangyang made" thousand -ton high -speed rail box beam beam transportation machine "Kunlun" is underway.

The total length of 120 meters. As the longest high -speed rail bridge machine in China, how to turn around is a great challenge, and it is even more precedent in China.

"Bridge machine turns around as a common step in the construction process of the beam, and the process is similar to the car to turn around." Wang Bo, manager of the Six Company of the China Railway 11th Bureau, said that the whole process needs to be nearly a hundred times. The longer the equipment requires the more diameter venue to turn around. The construction procedures are complicated and the input cost is high.

In order to ensure the completion of the "Kunlun", the six companies of China Railway Eleven Bureau and the Hanjiang Heavy Industry jointly invested the development force. After 60 days, a new type of heading device was developed at Xiangyang to the construction site.

According to reports, the head -up equipment is installed in the middle section of the bridge machine, and the motor reducer is used to drive the back to support the beam to turn around, so as to realize the original head -to -head movement movement, which can be turned around anytime and anywhere on the roadbed and bridge.

In addition, the heading device is also equipped with sensors and cameras to upload key parameters such as the weight weight and rotation speed. The system computing analysis, intelligent assistance construction personnel complete the turnover work more securely and efficiently.

At 20:30 that day, the head -up device was officially launched. The "Kunlun" started to rotate counterclockwise at a speed of 4.5 degrees per minute. 30 minutes later, the "Kunlun" completed the overall 180 degrees rotation requirements, and the head -up task was successfully completed.

"This created a pioneer of rotating device on the bridge surface in the nation's all -in -one." Wang Bo introduced that the heading device can be applied to 1,000 tons and 900 tons of various types of bridge machines. Compared with the previous 3 hours in the past 3 hours The process of turning around is only 30 minutes, and the work efficiency has been greatly improved. The cost of a single project can also save 200 to 3 million.
