deep in the tunnel

record the shape and size of the sample of XCMG Railway tz3s three arm (1) see Figure 2 (2), figure 2 (3), figure 2 (4) and table 2 (1), table 2 (2) during the 2018 BMW Shanghai exhibition, XCMG tz3s three arm rock drilling jumbo was heavily exhibited, and many domestic and foreign visitors came in an endless stream, praising it, which made every R & D personnel remember deeply. In 2012, the first three arm rock drilling jumbo in the industry was offline and put on the market in XCMG. As the first domestic brand to develop and manufacture three arm rock drilling jumbo, after years of market inspection, XCMG products have gained a good reputation among customers for their safe, efficient and stable performance. Behind all kinds of auras, there is a R & D technology team that always adheres to ingenuity and keeps improving

it's impossible to see it.

tz3s is a new generation of products. Market research is essential for innovation and upgrading on the basis of existing product technology. After receiving the market research task, the research group composed of Chen Baolei, Liang Fengyuan, Zhao Jiandong and Niu Yong immediately held a meeting, the main topic of which was where to conduct the research and what the research focus was. After intense discussion and a large amount of information collection, it was finally locked in a construction site near Chrysanthemum Village, Lishui, Zhejiang Province, where a tunnel using a foreign brand of rock drilling jumbo was under construction

the source of information is unknown, the completion of the project is unknown, and the user information is unknown... Methods are always more difficult than difficulties. With the "one track" spirit of worker Xu, the research team immediately set off. Chrysanthemum village is located in the deep mountains, and the traffic is extremely inconvenient. The research team rode the rented electric car and bumped along the mountain road. When they couldn't find the way, they asked around. In this way, four hours later, they finally found the construction tunnel. At this moment, the sky gradually darkened and the electric power of the tram was exhausted

in order to master the user's requirements for product parameters and construction methods in detail, the construction party was finally moved after patient coordination. It not only agreed to enter the construction tunnel, but also arranged professionals to accompany the explanation, and provided lighting equipment. The researchers were tireless, performed their respective duties, and were nervous and orderly. They checked the landform, collected rock samples, and understood the needs of users. Five hours of full research laid a solid foundation for later product design and technical research

if you don't know it, you can't do it.

tz3s three arm rock drilling jumbo's rod adding system is a customized device that uses crooked ideas to meet the special needs of users. On the eve of Shanghai BMW exhibition, it was found during the product test that the machining accuracy of the inner hole of the mounting base is not enough, resulting in accelerated wear of precision parts, reduced service life, and the inner hole of finished parts is incomplete, so general equipment can't realize secondary processing. At this time, the scheduled departure time is less than 10 days. If reprocessing, the departure time will be delayed

this mounting base is an optional part, which has little impact on the host. It is proposed that it can be replaced and improved in subsequent production. Immediately, this proposal was opposed by the team leader Zhou Zhongshang, "the machining accuracy of an option cannot be guaranteed. For users, how to guarantee the performance of the whole product and how to win the trust of customers?" Two days later, after unremitting efforts, the technical team finally found a special processing equipment, which could complete the secondary processing, and the mounting seat was repaired in time, ensuring that the tz3s three arm rock drilling jumbo was displayed at the end of the Shanghai BMW exhibition

cover the roll and feel

the fragrance of plum blossom comes from the bitter cold. After two years of unremitting efforts, the R & D team of tz3s rock drilling jumbo has deeply integrated technological innovation with customer needs, made breakthroughs one after another, and was fully affirmed by customers. In the future, they will continue to practice the product concept of "leading technology, indestructible use, and making handicrafts" for the maintenance method of the main machine of the universal testing machine, and will continue to optimize and improve with care and effort, so as to help XCMG develop with high quality
