Abstract

Technological innovation to ensure sustained and stable development of the power, is an important way to achieve the economic growth pattern. By technological innovation, you can expand the scale of production, optimize the structure of production technology, the integration of the production process, to improve the level of equipment, improve product quality and to improve the structure of varieties, fundamentally enhance the viability and competitiveness in the market. Therefore, exploration and research equipment technological transformation method has important practical significance for the survival and development of enterprises! Innovative ways and means to study the transformation of existing equipment the main content. The thesis is divided into two parts: the first part of the main building equipment new methods, approaches and processes of technological innovation, innovative design method based on the constrained space agency; innovative design method based on the constrained space agency on coal coking industry technological transformation and innovation research production in Pingmei devices. Discusses equipment technological innovation institutions innovative design methods, approaches and means of innovative design methods section based on the constrained space agency. The main steps are: (1) First, research site, the status of the production process and equipment, gather relevant information and understanding of the nature of the problem; mainly for work in two areas: first, the formation of a variety of constraints based on site conditions and the information collected, including space size, weight, orientation, layout, and other parameters restrictions, limitations of the working conditions of the working machine working environment constraints, economic conditions, operation and control of the way, other requirements (such as the industrial policy of the country, the scene of the technical conditions environmental protection, etc.) constraints, these constraints combine to become constrained space collection. Second to identify the cause of the problem on the most basic level, all the principles of the program to achieve functional, composed of the set of principles of the program. (2) to the constraints of space set a preliminary analysis and evaluation on the principles of the program set reasonable principle. (3) the use of institutional innovation theory to all the principles of the program into the various structural schematics, and to constrain the space set further analysis and evaluation of the different structures schematics, thereby the preferred agencies principle program. (4) the use of computer-aided technology parameters to optimize the structure, the establishment of a three-dimensional solid model using Pro / E simulation motion module simulation analysis of the kinematic model, which provide the basis for innovative design correctness. Technological transformation of the coking furnace Pingmei devices, mainly for the following tasks: (1) on the the top mounted the coke oven Pingmei device functions on-site research, analysis and the Pingdingshan Coal device production problems. (2) to improve the bulk density of the top of the coking furnace coal target constructed Pingmei bodies transformation of the set of constraint space, creates a carrier to Pingdingshan lever for the various principles of the program of the goals, and evaluation is preferably principle scheme preferably after conversion to the corresponding structure of the program, and their further preferably, the final selection of the cylinder - rolled rod structure for the final design. (3) using MATLAB Optimization Toolbox to optimize the design of four-bar linkage rolling device optimized parameters obtained to establish a three-dimensional model of Pro / E to motion simulation. To evaluate the impact of the rolling device the original Pingmei device using the ABAQUS finite element analysis of technological innovation after Pingmei rod. (4) respectively from the two aspects of the influence of the bulk density and the average bulk density of the top layer transformation after Pingmei effect were analyzed the results showed that the rolling apparatus can make the bulk density of the top layer of coal to 0.82t/m3 above, and This at the same time the amount of coal loading more than 4t.
