Chongqing light rail GDF240, GDF360 straddle telescopic device acceptance will be, in March 23, 2010 in Xinjin Teng in the Road Machinery Co., Ltd. was held. 15 experts from Chongqing Rail Transit (Group) Co., Ltd., Xi'an Railway Institute Advisory Supervision Company, Lin Tongyan Design Institute, Chongqing Traffic Scientific Research and Design Institute and Xinjin Tengzhong Road Construction Machinery Co., Ltd. participated in the acceptance of the products.
GDF240, GDF360 bridge-type track beam telescopic device is based on Chongqing Light Rail Caiyuanba Yangtze River Bridge track beam bearing load, displacement, angle, connection, life and other special requirements, using finite element analysis, breaking the inherent design ideas, To develop a new track beam telescopic device.
The experts of the first batch of four sets of GDF240, GDF360 straddle rail beam telescopic device main dimensions, assembly quality, appearance and painting, and so on-site sampling, and the development of the whole process of technical documents and records were carefully examined. After detailed verification and discussion, the expert acceptance group is very satisfied with the development work and product quality of the new straddle track retractor. It is agreed that GDF240 and GDF360 telescopic devices adopt the straight bearing system and the displacement control system composed of group rubber shearing springs. The function is clear, the force is clear and the displacement is even, which can meet three-direction stress, Dimensional displacement requirements. The zigzag noise-reducing plate is provided on the steel surface to realize seamless and smooth transition of the wheel, which can effectively reduce the driving impact and noise. The GDF240, GDF360 expansion and contraction device products meet the design and contract requirements, fully meet the Chongqing Caiyuanba bridge straddle rail transit construction project needs.
GDF series track beam telescopic device has a number of patents, the tread in the use of Tengzhong unique noise reduction patented technology, driving a smooth, low noise; load support systems and displacement control systems are flexible system, with a reliable load, anti-fatigue , Three-dimensional displacement and strong performance characteristics. The successful development of this type of expansion device provides a new product for domestic light rail transit projects, and will be widely used in domestic light rail transit construction projects.
