  Chapter 517 Anecdotes about the Drilling Hoist

  The meal was eaten at a restaurant in front of the factory.

  After the three of them sat down and ordered good dishes, Zhao Guoyang and Zhao Siyan talked about their understanding and thinking about the drilling hoist.

   "Siyan, I know that the main direction of your graduate student is vehicle manufacturing. You may be a little unfamiliar with mining machinery and equipment. I just have time today. Let me have a brief chat with you."

  When Zhao Guoyang said this, Zhao Siyan clapped her hands and laughed, "That's great, Guoyang. In the past two days, I went to the workshop several times, just to get a more comprehensive and detailed understanding of the situation."

   "Now that you, an expert in the technical field, tell me personally, that's what I wish for. I will definitely listen to it."

  Zhao Guoyang wrung his fingers and said in an orderly manner: "Well, generally speaking, mining machinery equipment refers to machinery that is specialized in mining, mineral processing, and prospecting."

   "A large number of cranes, conveyors, fans and drainage machinery used in mining operations are collectively referred to as mining machinery and equipment."

   "In terms of usage, mining machinery and equipment can be divided into mineral processing equipment, mining equipment, prospecting equipment, and transportation equipment. You should know all of these."

   Speaking of this, Zhao Guoyang pointed to Li Zhaohe, who was listening attentively, and said: "The best vibrating feeder that Lao Li sold in his factory before is a kind of mineral processing equipment."

Hearing this, Li Zhaohe nodded with a "huh" and said: "Yes, Minister Zhao, you may not know that when the factory was going to pack and sell before, Mr. Zhao had a relationship with the former because of the vibration feeder The South Koreans who came to buy it confronted each other theoretically."

   "Mr. Zhao's understanding of mining machinery and equipment is really unexpected. What's even more rare is that he didn't have a background in mining machinery, which is even more amazing!"

  Listening to Li Zhaohe's sigh, Zhao Siyan showed her face and responded: "Mr. Li, you are right. The most powerful thing about our Chairman Zhao is his erudition and talent."

   "I still remember when I first met Mr. Zhao, I still felt that I was a graduate student, and I felt somewhat superior."

   "Who knows, after chatting casually with him, I was dumbfounded!"

   Speaking of this, Zhao Siyan looked at Zhao Guoyang with a look of admiration.

   "Later, I have summed up Chairman Zhao's knowledge in four words - bottomless."

  Seeing Zhao Guoyang's indifferent look, Zhao Siyan stuck out her tongue and said, "Mr. Zhao, I didn't say that, it's the teacher's evaluation of you!"

  After Zhao Siyan finished speaking, Li Zhaohe nodded approvingly.

   As for Zhao Guoyang, he was somewhat surprised to learn that Professor Zhu Maotao had given him such a high evaluation in private.

  The three of them were chatting, and the topic returned to the drilling hoist.

  Regarding the concept of the drilling hoist, Zhao Siyan has also spent a lot of time researching it these days.

  When this topic was mentioned at this time, she blinked and said: "I also know a lot about mining machinery such as drilling hoists."

   "It refers to the main transportation equipment that connects underground and ground in mining engineering?"

  After Zhao Siyan said this, Zhao Guoyang and Li Zhaohe nodded at the same time.

Seeing that both of them did not deny their statement, Zhao Siyan continued: "I have read the information in detail these two days and learned that the drilling hoist is usually installed on the ground, but as for its working method, because there is no For the real thing, I can’t make a judgment for the time being.”

  Zhao Siyan's words are true.

   Indeed, the materials collected by technicians in the 1990s were generally paper-based, either books or magazines.

  Although there are a few illustrations in books and magazines.

  But it is a bit exaggerated to fully understand the operating principle of such a complicated machine only by relying on these illustrations.

  Encountered such a situation, the only way to answer questions for newcomers is to explain the mysteries through oral explanations by experienced technical staff.

   Facing the troubles brought about by the limitations of this era, Zhao Guoyang has no better solution for the time being.

  Hearing Zhao Siyan's confusion about the working method of the drilling hoist at this time, Zhao Guoyang explained it to her in detail.

   "Siyan, the working method of the drilling hoist is actually not complicated. In most cases, it uses the wire rope to drive the hoisting container to run along the shaft or the ramp."

   "In terms of usage, this kind of mining machinery plant is often used in shafts and inclined shafts to lift coal, ore, gangue, and lift personnel, lower materials, tools and equipment, etc."

  Seeing Zhao Siyan's half-understanding expression, Zhao Guoyang made a gesture and said, "Simply speaking, the principle of movement of the drilling hoist is somewhat similar to the pulley structure in our high school physics."

   "Of course, the internal structure of the drilling hoist must be much more complicated than the pulley structure..."

  Zhao Guoyang's vivid explanation made Zhao Siyan understand a lot.

  She nodded and said: "Chairman, if you say it like this, I probably have a bottom line. To put it bluntly, this kind of mining machinery is similar to an elevator?"

   "Well, that's right!"

  Zhao Guoyang nodded and said: "In foreign countries, the drilling hoist is sometimes called a mine elevator. People call it a special form of elevator, but in my personal opinion, it is more like a simple elevator."

  Although Li Zhaohe didn't know much about drilling hoists, he still knew a little more than Zhao Siyan.

After listening to Zhao Guoyang's narration, he followed up and said: "Mr. Zhao is right. When I visited a large mining equipment machinery factory in the west, I saw that they purchased natural A foreign drilling hoist."

   "It looks like an elevator!"

  Listening to Zhao Guoyang and Li Zhaohe's explanations in turn, Zhao Siyan's understanding of the drilling hoist gradually became three-dimensional.

  Because she has been engaged in scientific research, Zhao Siyan is better at thinking when she comes into contact with fields she is not familiar with.

After listening to Zhao Guoyang and Li Zhaohe's explanation, she asked a question: "Chairman, after hearing you and Mr. Li introduce the drilling hoist just now, I feel that this kind of mechanical equipment should not be widely used. Bar."

  Zhao Siyan continued with some doubts: "I read from a magazine that after a mineral deposit is excavated, the starting point should be a small area."

   "That is to say, the drilling work should be carried out in a small area. Then the demand for the drilling hoist should not be too great, right?"

  After Zhao Siyan asked this question, Zhao Guoyang quickly understood what she meant.

  He smiled and explained: "Siyan, the magazine you read should be quite old, right?"

   "Uh, yes. It seems to be an article published in "World Industrial Technology" in 1979. I thought it was a bit interesting at the time, so I specially recorded it."

  Zhao Guoyang nodded suddenly and said: "The mining method you mentioned did exist. But it was more than ten years ago, and it is already in the past tense."

   "At present, except for some rare metal mines, most coal mines and iron ore mining are concentrated and intensive."

   "It is impossible to carry out mining in only one area. Sometimes it is common to drill wells in more than ten or twenty areas at the same time!"

   Speaking of this, Zhao Guoyang paused for a moment and then continued to speak: "Moreover, in modern mining activities, safety issues are becoming more and more important, both domestically and internationally."

"In the process of transporting people and things in the mine, as a very important transportation tool, drilling hoists must have a certain number. Therefore, during the mining process of a mine, the number of drilling hoists may reach dozens, or even up to Hundreds."

   "Especially the underground conditions and working environment are more harsh and difficult than those on the ground. Therefore, in order to ensure the safety of personnel, two or three drilling hoists are often working at the same time..."

   What Zhao Guoyang said, not only Zhao Siyan, but even Li Zhaohe had never heard of it.

  When Zhao Guoyang said he wanted to build a drilling hoist, he didn't tell him the details of the market demand. He just told him that after this kind of machine is produced, it will definitely sell well.

  Although he has great trust in Zhao Guoyang himself, his words are unfounded after all. Li Zhaohe is a little uncertain about whether this mining equipment can achieve good results.

  After listening to Zhao Guoyang's detailed explanation at this time, the last worry in Li Zhaohe's heart disappeared.

  As for Zhao Siyan, she also had a face full of enlightenment.

She stroked her hair on her forehead, nodded lightly and said: "Well, according to this, this drilling hoist is really an indispensable equipment in mining activities, so we don't need to sell it Too worried!"

Zhao Guoyang said with a "huh" and said, "Don't worry about this Siyan. When I chose this drilling hoist as the first flagship product of our SMS company, the first thing I considered was the market demand. "

   "If I didn't have confidence in this product, I wouldn't be so determined to choose it as my main product!"

  Zhao Siyan let out a "huh", as if remembering something.

   She tilted her head to look at Zhao Guoyang and said, "I heard what you said, Chairman, I have another question..."

  Zhao Guoyang shrugged and made a "but it's okay to say" expression.

   "My question is, since the market demand for drilling hoists is huge, why is there no manufacturer in China that produces this kind of machinery? Could it be because the technical level is not up to par?"

  Zhao Siyan frowned slightly and said: "But according to the design theory of the drilling hoist you proposed, it seems not complicated, why..."
