On the graduation thesis of construction machinery model essay I: Analysis of influencing factors of international competitiveness of construction machinery industry I. International competitiveness
International competitiveness is not an abstract concept. The strength of international competition is closely related to factors such as region, policy, industrial scale and core technology. For the analysis of international competitiveness, we need to start from these aspects and make reasonable analysis and rational judgment based on the objective facts of related factors, so as to draw a conclusion.
(1) Regional factors include natural environment factors and humanistic and social factors.
The richness of resources and the convenience of location are the starting points for our analysis of natural environmental factors. Social and humanistic factors mainly include infrastructure construction, population potential and people's education level. As far as China is concerned, the main construction machinery industries are located in Central China and East China, which are rich in natural resources such as coal, iron ore and hydropower, providing a good material foundation for the development of construction machinery industry. Moreover, the geographical location of this area is superior and the production cost is greatly reduced. It is not difficult to see that the construction machinery industry in China has inherent natural advantages. As the economic growth point of China, Central China and East China have been continuously investing in the transformation and upgrading of infrastructure, and the degree of perfection is almost the same as that of developed countries. This area is densely populated, providing a large number of labor force for the construction machinery industry, with huge population potential, which makes this area have strong consumption capacity and become the main domestic market of the construction machinery industry. Pragmatic and industrious traditional spirit and pioneering modern concept make this area full of vitality and vigor. Such regional factors make China's construction machinery industry have great potential and vitality, and its competitive advantage in the world is already very obvious.
(2) Policy factors mainly include national policies, regional policies and the management policies of enterprises themselves.
Since the reform and opening up, China has put economic construction in the first place, which has become the overriding core task. The state strongly supports the development of the construction machinery industry, and gives preferential tax treatment from the national level to promote its development. In order to ensure the speed and level of economic development in the region and spare no effort to help and support the development of related industries, the regional government has given many preferential policies at the regional level. Enterprises themselves are constantly improving their own management level, constantly learning from foreign excellent management experience, making the management system in line with international standards, and clearing obstacles for their own development at the enterprise management level. Generally speaking, both countries and enterprises are providing convenient conditions for the development of construction machinery industry from their own perspective. It is under these convenient conditions that the international competitiveness of China's construction machinery manufacturing industry can be greatly improved.
(3) Scale refers to the cluster advantage through related industries.
Reduce production costs and enhance the ability to use resources and resist external risks. China construction machinery manufacturing industry has obvious advantages in this field. The existence of industrial bases in Central China and East China has made good use of the advantages of clusters, greatly reduced production costs, improved the ability to use resources, well controlled risks and paved the way for their own development. The existence of scale advantage can enjoy the benefits brought by the complete upgrading of infrastructure in a period of time, and quickly transform this benefit into the production field, thus enhancing its international competitiveness.
(d) As an application industry
The international competitiveness of construction machinery industry is directly related to advanced technology. The fierce international market competition is not only the price and after-sales service of products, but also the game of technology contained in products themselves. Only higher and higher technology can guarantee the international market share of Purple God and have the last laugh in the fierce fighting. However, due to the late start of China's construction machinery industry, it lacks the corresponding mastery of core technologies. Temperature? , slightly inferior in international competition. It can't compete well with traditional powers such as the United States, the European Union and Japan, which requires us to make adjustments to fill the shortcomings in this respect. Enhance international competitiveness.
Second, suggestions and strategies
(A) give full play to China's talent advantage.
Enhance their own innovation ability, Industry-University-Research linkage, promote research with production and teaching, and research and teaching. This ensures that China's engineering technology industry has its own core technology, and it does not lag behind or even have advantages in technological competition with the United States, the European Union and Japan.
(two) make full use of national and regional policy support.
Take advantage of this favorable condition, speed up its own structural adjustment and build itself into a more scientific and efficient production department. At the same time, make good use of cluster advantages, reduce production costs, provide good price advantages for foreign competition, and grasp the price initiative.
Third, the conclusion
The promotion of the international competitiveness of China's construction machinery industry is a slow process, which requires us to constantly overcome difficulties and forge ahead. Through the preliminary discussion of the factors affecting international competitiveness, we have made clear the direction of our future efforts. We are confident that under the superior social system and reasonable and efficient enterprise management system, we will catch up with others, enhance the international competitiveness of the engineering technology industry and let it go further.
On the graduation thesis of construction machinery, Fan Wener: Analysis of the management points of large-scale construction machinery I. Maintenance and repair of large-scale construction machinery in wind power engineering construction
1 Strengthen the maintenance of large-scale mechanical equipment: equipment is an important part of wind power projects. If the equipment fails due to improper and untimely maintenance, it will not only cost a lot of maintenance expenses, but also delay the normal operation of the construction period. Therefore, in the process of wind power project construction, the use and maintenance of large construction machinery is the premise to ensure the normal construction. The integrity of equipment mainly depends on the maintenance, correct operation and reasonable use of operators, who need to have a certain sense of responsibility and take good care of the equipment they use. Always keep the equipment clean and tidy. If you need to refuel large machinery, you must refuel regularly and strictly check whether there is oil leakage. Strengthen daily inspection. In daily operation, the equipment must be observed at any time. Once the problem is found, it needs to be handled and solved in time to prevent the equipment failure from expanding and aggravating. The safety of large-scale hoisting machinery can not be separated from daily maintenance work, and it is also the most important safety issue to ensure the construction machinery and equipment. It is very necessary to form a professional group with skills, experience and responsibility in wind power projects. The team includes mechanical operators, maintenance personnel, maintenance electricians and professional technicians. , and must be trained in relevant skills and have many years of experience in mechanical maintenance. Large hoisting machinery needs to be maintained in accordance with the instructions and relevant regulations, and it needs to be approved by relevant departments. Before carrying out large-scale mechanical operation, the operators involved in the operation must be given safety guidance and technical disclosure. Ensure that operators can carry out construction in a standardized, safe and accurate manner, and regularly record the problems and maintenance effects of mechanical equipment during use and maintenance, and file them. At the same time, improve the responsibility of maintenance personnel in the installation process. After the machine is installed, it must be debugged according to the relevant operation requirements. Individual large machinery requiring special inspection shall be inspected by the special inspection office. Only when the inspection is up to standard and there is a safety inspection certificate can it be used. Through careful and comprehensive inspection and audit, the potential safety hazards of large machinery can be effectively avoided. Technicians, maintenance workers, maintenance personnel and operators all need comprehensive training. In particular, technicians and operators must strengthen the training of operation technology, safety regulations and maintenance technology. Training forms can be carried out in different ways, such as after-sales knowledge explanation by manufacturers, equipment maintenance and short-term study. The ultimate goal of all training is to make technicians, maintenance personnel, maintenance personnel and operators understand the working principle of large machinery while mastering relevant technologies.
2. Strengthen the inspection and maintenance of large-scale mechanical equipment: the inspection of large-scale mechanical equipment is the basis for ensuring safe operation. First of all, the operator should conduct a comprehensive inspection of the equipment before each operation, mainly checking the safety of the machinery (such as dripping, leakage and leakage) and the protective devices of the machinery. For the use and maintenance of large machinery, the management department needs to conduct regular inspections to ensure the safety of operators and equipment. The inspection contents include the implementation of relevant requirements and regulations, equipment use and maintenance, equipment protection devices, etc. Weekly inspection of equipment is also required every week. If there is any problem with the equipment during the inspection, it is necessary to stop the operation immediately. After receiving the rectification notice, the relevant departments must inspect and maintain the equipment in time, and audit the standardized operation to ensure the timeliness and accuracy of equipment maintenance, so as to ensure the safety of mechanical equipment and the smooth progress of the whole project. Managers of relevant departments should implement the equipment maintenance work to everyone, teams and individuals, and ensure that each equipment is inspected by special personnel. Operators need to inspect, maintain and maintain large machinery according to the prescribed procedures, and electrical and maintenance personnel also need to inspect and maintain it regularly, and record the problems found in the inspection for early analysis and treatment. Regular inspection and maintenance of equipment can ensure that the equipment is always in a safe and controlled state.
Two. Daily storage of large-scale mechanical equipment for wind power projects
Because wind power projects are located in remote areas, usually far away from cities, the available resources around them are very limited and the transportation is not very convenient. These factors have caused great difficulties to the daily maintenance and repair of large machinery. In the process of large-scale mechanical operation, if it cannot be repaired in time, it will not only seriously affect the progress of the construction period, but also bring dangerous factors to the working environment. Therefore, maintenance tools and spare parts play a very important role in maintaining machinery. According to the characteristics of each machine, we must reserve some common maintenance tools and spare parts. If a certain type of large machinery is not commonly used, but it is important, it is also necessary to stock its accessories. Inventory needs to be made according to the working experience of mechanical operators and maintenance personnel, or through communication with factory technicians. At the same time, according to the actual situation of the construction site, establish an inventory list of spare parts and equipment to ensure that the actual items are consistent with the inventory list and keep the spare parts in good condition.
Third, the conclusion
