Jiangyan Heavy Industry Co., Ltd. CN290 Hydraulic Excavation Rock Drill R & D Success

Recently, Jiangyan Heavy Industry has successfully developed a modified rock drilling machine. This is the company's implementation of a differentiated development strategy. It is a joint venture with Xiangtan University, Hunan University of Science and Technology, and Shenzhen Kaiqiangli Technology Co., Ltd., with industrialization as the goal, enterprises as the mainstay, and industry-university research and development. - Integrated comprehensive technology development platform.
Based on the mature technology platform of the company’s existing 9-ton excavator, it has passed the matching technology of rock drilling equipment, the integration technology of hydraulic rock drilling equipment and excavators, the rock drilling control technology of rock drilling machines, and the key technologies of rock drilling rigs. Research on a series of key technologies such as processing technology, industrialization, hydraulic boring gun test and test technology, CNZ90 rock drill completed the prototype offline in June this year, and conducted rock drills and industrial reliability on the prototype in Lianhua Mountain, Xiangtan. test. On the basis of obtaining periodical results, rectification and optimization are conducted in light of the deficiencies exposed in the trial. In order to achieve the preset goals, under the careful guidance of the company's leaders, the company's various departments closely cooperated, focused on the technical and processing problems of the CNZ90 hydraulic excavator rock drill thruster, etc. After repeated repair and rectification verification, the CNG90 prototype has finally reached the original Design requirements. The successful development of the CNZ90 Rock Drilling Rig effectively freed itself from the current situation in which domestic drilling equipment relies on imports and solves the technical development and manufacturing bottlenecks of the industry. At the same time, the CNG90 rock drilling equipment research and development has accumulated experience for the company's subsequent development of drilling equipment such as CNNZ70 and CNNZ220. It provides technical support for the company to expand its market area and increase its market share. (This article comes from Jiang Yan Liu Zhiyuan)
