Abstract
Since the 20th century, the new technology revolution, along with the coal mining technology and equipment, rapid development.Mining actively advanced mechanical-electrical integration, and application of automation technology, we developed a high production capacity, high-performance mining technology and equipment, extensive application of computer technology to achieve a mine production process automation control, achieve a high yield and efficient mine production.
Mining mechanization of the coal industry to increase production, improve labor productivity, improved working conditions, Production of security necessary technical means. Comprehensive mechanized coal face equipment -- Shearer, hydraulic support and scraper conveyor represented.
Hydraulic support is the important shoring equipment in mechanism excavating workface, and its investment occupy around 70% of full set of integrated matching equipments, and the main function is shoring roof floor, maintaining safety operation space, meanwhile advancing transporter and shearer. Leg is the main component part of hydraulic support, and its function can directly determine the shoring capacity of hydraulic support, with the development direction to large working resistance , so that legs become to be with more and more large cylinder diameter, high dependability. In order to adapt the quick market development speed, one new assistant, design technology is needed, so to achieve the purpose of expediting design speed, reducing the calculation work, also simulating automatic safety factor checking when at test state.
The passage of this issue, the column to simplify the design, verification, manufacturing processes and improve the efficiency of the design process and reduce the manufacturing process, the development of new products to enhance the speed and response capability, enhance product reliability, and proceed to create greater efficiency, thereby enhancing the competitiveness of enterprises.
