"Jiangjin made" the first "head of the roadheader" successfully installed

A few days ago, the author learned from the Desen Industrial Park in Jiangjin District, Chongqing: The first TBM main drive reducer independently developed by CSSC Chongqing Gearbox Co., Ltd. (abbreviated as “Heavy Gear Company”) located in the park was recently Ship Heavy Industry (Qingdao) Rail Transportation Equipment Co., Ltd. successfully completed the installation and received unanimous praise.

The TBM machine is a full-surface tunnel boring machine. In China's engineering field, tunnel boring machines used for soft ground are conventionally referred to as shield machines, and tunnel boring machines used for rock formations are referred to as TBM machines. Compared with shield machines, TBM machines are known as the "king of roadheaders" in the construction machinery industry due to their ability to apply a more severe engineering environment, as well as extremely high reliability and longevity of equipment.

Heavy tooth company was born in the "three-line construction" period, has a 50-year hardened gear transmission and coupling, shock absorber development history. For half a century, the company has vigorously promoted the “artisan spirit”, and its product design and manufacture has always maintained a leading position in the country and reached the international advanced level. The products are sold well in China and more than 40 countries and regions around the world and have been highly recognized by customers.

As one of the key R&D projects in the “13th Five-Year” new product technology planning of the heavy tooth company, this successful TBM machine is a high-tech company specially developed for China Shipbuilding Heavy Industry (Qingdao) Rail Transportation Equipment Co., Ltd. Reliability equipment. The equipment products have complex working conditions, compact structures, and high reliability and efficiency requirements. The heavy tooth company received product design, manufacture, assembly, inspection and test from the first order and tracked in the form of project management. It succeeded in overcoming the related technologies and manufacturing difficulties such as machine high power density, high load bearing, high reliability, etc. The technical parameters are consistent with the imported equipment of the same model, and all the experimental data have effectively met the customer's requirements.

According to professional sources, the successful installation of the TBM machine not only proves the strong technical strength of the heavy tooth company's new product development, but also more importantly conforms to the development needs of underground engineering such as urban rail transit and river crossing tunnels in China, and improves the TBM machine. The level of localization has important practical significance.
