in the year of graation, I came to the coal mine and was assigned to the excavation team to work in three shifts, including blasting, mechanical excavation, anchoring, and carrying cement sleepers and single pillars. All the work of the excavation team was heavy manual work, which was very hard. Especially when I was on the night shift, I could fall asleep standing up, and I didn't have autumn clothes and trousers on my body, I don't even have the strength to take chopsticks when I eat after work, so I can fall asleep when I fall into bed. It's hard to work hard in the mine for a year, but it can also train people. What I thought at that time was that as long as I wasn't tired to death, I would go on working
in the second year, I was assigned to the ground machine repair workshop to do mechanical repair work, such as lathe, welding, recer, coupler, roadheader, shearer, pumping station, belt conveyor, winch, etc. anyway, the underground mechanical equipment was almost repaired. I learned a lot in this year. I took notes while repairing things, and then read the books when I went to school after work, If you work harder, you can undertake the repair work independently in a year
in the first half of the third year, I was assigned to work as a mechanical repairman in the fully mechanized mining team. In retrospect, that time was the most pleasant time for me, because the repairman in the fully mechanized mining team was a technical type of work. As long as the fully mechanized mining equipment was normal, the leader almost didn't care, especially free, and if there was no problem, I would get out of the well ahead of time. However, one thing is that the mobile phone must be turned on 24 hours a day. As soon as the equipment breaks down, it has to go down to repair the equipment in the middle of the night. There are almost no weekends, because when others rest, you have to go down the well to repair the responsible equipment
in the second half of the third year, I was assigned to work as an electrician in the mechanical and electrical team. From the beginning of my apprenticeship, I always felt that it was much easier to work as an electrician than a repairman. After three months of study, I was on ty independently, because the principle of coal mine electrical equipment was much simpler than that of school. As long as I went to school, some electrical skills were easy to master, and then I dealt with several rare faults independently, Almost able to cope with the electrical operation of the coal mine.
Sprocket assembly is composed of sprocket and connecting roller. It is an important part of scraper conveyor, and it is also the most torque part of conveyor. Therefore, in the process of purchasing sprocket shaft group, many problems should be considered, and we must be very careful. Only in this way can we choose high-quality sprocket shaft group, prolong the service life of sprocket shaft group, and improve work efficiency, otherwise, In the use of the process is prone to accidents, resulting in labor and money, so what should be paid attention to in the process of purchasing sprocket shaft group? What is the price of sprocket shaft group
what problems should be paid attention to in the process of purchasing sprocket shaft group:
with the development of coal machinery and the national rectification and merger of small and medium-sized coal mines, large-scale fully mechanized mining equipment is more and more widely used in coal mines With the development of heavy-ty scraper conveyor, there are more and more types of scraper conveyor, and the models proced by major coal machine manufacturers are also different. As the main vulnerable parts of scraper conveyor, sprocket shaft group is not universal, which makes it difficult to determine when purchasing. So what problems should be paid attention to when purchasing sprocket shaft group? We summarize the following aspects
First, the main engine manufacturer of sprocket shaft group. As there are many manufacturers of scraper conveyor, the sprocket shaft group of each manufacturer can not be used in general, so when purchasing, we must first determine which manufacturer of scraper conveyor is suitable for sprocket shaft group. At present, the most important domestic scraper conveyor manufacturers are China Coal Zhangjiakou coal machinery plant, Ningxia Tiandi Benniu, Shandong mining machinery, Shanxi coal machinery plant and Zheng coal machinery Second, the determination of drawing number of sprocket shaft group. Even for the same scraper conveyor manufacturer, the sprocket shaft group applicable to the same scraper conveyor model may not be the same. Therefore, it is necessary to determine the drawing number of the sprocket shaft group. Each sprocket shaft group has only one set of drawings. As long as you find the drawing number of the sprocket shaft group and have the corresponding drawings, you can ensure that the sprocket shaft group proced will not make mistakes Third, the material selection of sprocket shaft group. Due to the increasing power and transportation volume of scraper conveyor, there are great requirements for the toughness and strength of sprocket shaft group. If the material selection is not appropriate, the sprocket shaft group will be prone to accidents in the use process, affecting the proction progress, and even safety accidents. At present, the commonly used materials are 42CrMo and 45crnimnmu. When selecting, the appropriate materials should be selected according to the transportation volume Fourthly, the manufacturing process of sprocket shaft group. Due to the high requirements for the toughness and strength of the sprocket shaft group, the manufacturing process can not be careless. At present, the manufacturing process of the sprocket shaft group mainly includes forging, casting and welding. Small ordinary mining scraper conveyor can choose casting and welding sprocket shaft group. For large fully mechanized sprocket shaft group, in order to ensure its performance requirements, only forging sprocket shaft group can be selected, and heat treatment, quenching and tempering and other processes can be carried out
when purchasing the sprocket shaft group, we should pay attention to the above aspects. Basically, the sprocket shaft group can basically meet the performance required by the current scraper conveyor, but there is another point to pay attention to, that is, when the scraper conveyor is running, we must pay attention to the wear of the sprocket shaft group at any time to avoid accidents

the above is about the problems that should be paid attention to in the process of purchasing sprocket shaft group and the price introction of sprocket shaft group manufacturer, In the purchase of sprocket shaft group must be very careful, understand all the situation before making a decision, and in the purchase can not be greedy for small cheap Oh, to buy high-quality procts is the king. At the same time, when using the sprocket shaft group, you should often check the wear of the sprocket shaft group and take preventive measures to avoid accidents. I hope the above contents can help you
most sprocket quenching methods are high frequency quenching. But this kind of quenching is more troublesome, need a tooth a tooth quenching, relatively slow; Even worse, the hardness gradient of quenching is not suitable. Gears are easily damaged
the better quenching method is flame quenching, and the hardness gradient of flame quenching is the most ideal. But the difficulties are uniformity and speed. To solve this problem, we need to use CNC and automatic quenching equipment
the automation equipment has been used in Shanxi coal machinery and Shandong mining machinery. The effect is quite good, which can completely replace the similar imported equipment from Germany
