Information

  The newly built Guanting Reservoir Bridge between Beijing and Zhangjiakou Railway, which crosses the Guanting Reservoir in parallel with the Beijing-Baoji Railway, is a key project serving the Winter Olympics. The bridge adopts the patented mobile beam inspection vehicle technology developed by our company, and a total of 2 lower end trackless inspection vehicles are installed at the bottom of the steel bridge to meet the daily inspection and maintenance needs of the Guanting Bridge. As of now, the Fifth Branch Factory has successfully completed 656 track pendants for inspection vehicles, and the installation process of inspection vehicles is half a month earlier than expected.

  During the construction of the project, there are many difficulties. Due to the poor geographical location of the bridge, in windy weather, except for the initial parking position of the bridge on the ground, the rest are on water, and cranes cannot be used. In response to this difficulty, Ma Yanqing, the squad leader responsible for the installation of the project, devised a plan in advance to design a fixture for installing pendants. The tooling is fixed on both sides of the traveling mechanism in the forward direction, and a working platform is provided at the end of the tooling, and its position is below the guide of the traveling mechanism. This tooling can be used to install pendants while moving forward, which improves the installation efficiency and reduces extra work.

  The installation of the pendant has been solved, but the transportation of the pendant has become a major problem. Due to the restrictions of the construction site, the pendant can only be transported to the starting position on the bridge by the crane, that is, the parking position, so that the pendant can only be transported to the inspection truck. After the installation is completed, return to the starting position and re-transport the pendant. This is a waste of time and labor. The squad leader also designs and manufactures the pendant transport tooling. The tooling can quickly transport the pendant to the designated location, improve efficiency and reduce labor intensity. Shortened the construction period.

  The Fifth Branch Factory has always taken “the key to overcome difficulties and ensure quality, unite as one to promote delivery” as its core, and reasonably arrange the construction plan so that the first inspection vehicle of the government hall is successfully installed. At the same time, we have accumulated rich experience for our company to install inspection vehicles of this kind of environment.
