The meal was eaten at a restaurant in front of the factory. \ After the three of them sat down and ordered food, Zhao Guoyang talked to Zhao Siyan about his understanding and ideas of drilling hoist.
"Siyan, I know that the main direction of your graduate students is vehicle manufacturing, and you may be a little unfamiliar with mining machinery and equipment, so I have time today, so I'll have a brief chat with you."
When Zhao Guoyang said this, Zhao Siyan clapped her hands and smiled: "That's great, Guoyang, in the past two days, I have been to the workshop several times, just to have a more comprehensive understanding of this aspect of the situation." ” "Now that an expert in the technical field like you is telling me in person, I can't ask for it, and I will definitely listen to it."
Zhao Guoyang wrenched his fingers and said methodically: "Then, generally speaking, mining machinery and equipment refers to machinery specializing in mining, mineral processing, and prospecting. ” "A large number of cranes, conveyors, ventilators and drainage machinery used in mining operations are collectively referred to as mining machinery and equipment."
"In terms of use, mining machinery and equipment are divided into mineral processing equipment, mining equipment, prospecting equipment and transportation equipment, etc., which you should know."
Speaking of this, Zhao Guoyang pointed to Li Zhaohe, who was listening carefully, and said: "The best vibrating feeder sold by Lao Li in their factory before was a kind of mineral processing equipment. ” Hearing this, Li Zhaohe nodded and said: "Yes, Minister Zhao, you may not know that when the factory was about to be packaged and sold, Mr.
Zhao had a theoretical confrontation with the South Koreans who came to buy it because of the vibrating feeder. ” "Mr.
Zhao's understanding of mining machinery and equipment is really unexpected.
What's even more rare is that he himself is not from a mining machinery background, which is even more amazing."
Listening to Li Zhaohe's sigh, Zhao Siyan responded with a smile: "Mr.
Li, you are right.
The most powerful thing about our Chairman Zhao is his erudition. ” "I still remember the first time I met our Mr.
Zhao, I still felt that I was a graduate student, and I had a sense of superiority."
"Who knows, after a casual chat with him, I'm dumbfounded" Speaking of this, Zhao Siyan looked at Zhao Guoyang with a hint of admiration in her eyes.
"Later, I summed up Chairman Zhao's knowledge, but the four words are bottomless."
Seeing Zhao Guoyang's very indifferent appearance, Zhao Siyan stuck out her tongue and said, "Mr.
Zhao, this is not what I said, it was the teacher's evaluation for you."
After Zhao Siyan finished saying this, Li Zhaohe nodded thoughtfully.
And Zhao Guoyang was somewhat surprised to learn that Professor Zhu Maotao had given him such a high evaluation in private.
The three of them chatted, and the topic returned to the drilling hoist.
Regarding the concept of drilling hoist, Zhao Siyan has also spent a lot of time studying it these days.
At this time, when this topic was mentioned, she blinked her eyes and said: "I also know a lot about mining machinery and equipment such as drilling hoists. ” "It refers to the main transportation equipment that connects the underground and the surface in mining engineering."
After Zhao Siyan said this, Zhao Guoyang and Li Zhaohe nodded at the same time.
Seeing that neither of them denied their statements, Zhao Siyan continued: "I have read the information in detail in the past two days and learned that the drilling hoist is usually installed on the ground, but I can't make a judgment on how it works because there is no physical object. ” Zhao Siyan's words are also sincere.
Indeed, the materials collected by technicians in the 90s were generally mainly on paper, either books or magazines.
There are also a small number of illustrations in books and magazines.
But it would be an exaggeration to try to fully understand how such a complex machine works just by relying on these illustrations.
In such a situation, it can only be taught by senior technicians orally, and the mystery can be explained thoroughly in person, so as to answer questions and solve doubts for newcomers.
Faced with the troubles caused by the limitations of this era, Zhao Guoyang has no better way for the time being.
At this time, hearing Zhao Siyan's confusion in the working method of the drilling hoist, Zhao Guoyang explained to her in detail.
"Siyan, the way the drilling hoist works, in fact, is not complicated, in most cases, it is with the help of wire ropes, driving the hoisting vessel to run along the wellbore or ramp."
"In terms of use, this kind of mining machinery plant is often used in vertical and inclined shafts to lift coal, ore, gangue, as well as to lift people, lower materials, tools and equipment, etc."
Looking at the look on Zhao Siyan's face that seemed to understand whether he understood or not, Zhao Guoyang gestured and said: "To put it simply, the motion principle of the drilling hoist is somewhat similar to the pulley structure of our high school physics. ” "Of course, the internal structure of the drilling hoist must be much more complex than the pulley structure."
Zhao Guoyang's apt explanation made Zhao Siyan understand a lot at once.
She nodded and said: "Chairman, if you say that, I probably have the bottom, 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, drilling hoists are sometimes called mine elevators.
People call it a special form of elevator, but in my personal opinion, it's more of a simple lift. ” Although Li Zhaohe doesn't know much about drilling hoists, he still knows 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 and machinery factory in the west, I saw a drilling hoist purchased from abroad. ” "It looks like a lift."
Listening to Zhao Guoyang, 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 that she is not familiar with.
After listening to Zhao Guoyang and Li Zhaohe's explanations, she asked a question: "Chairman, just after listening to you and Mr.
Li introduce the drilling hoist, I feel that this kind of mechanical equipment should not be widely used." ” Zhao Siyan continued with some doubts: "I read in a magazine that after a mineral deposit is excavated, the starting point should be a small area. ” "In other words, the drilling work should be carried out in a small area.
Then the demand for drilling hoists should not be too big, right?"
After Zhao Siyan asked this, Zhao Guoyang quickly understood what she meant.

He smiled and explained, "Siyan, the magazine you read should be quite old."
"Uh, yes.
It seems to be an article published in 1979 in the world of industrial science and technology.
At the time, I thought it was a bit interesting, so I recorded it. ” Zhao Guoyang nodded abruptly and said, "The mining method you said does exist.
But it was more than a decade ago, and it is long gone. ” "Now, except for some rare metal mines, most of the coal and iron ore mining is concentrated and intensive."
"If you start a mine, it is impossible to only carry out in one area, and sometimes, it is common for more than a dozen or 20 areas to drill at the same time."
Speaking of this, Zhao Guoyang paused for a moment and then continued: "Moreover, in modern mining activities, more and more attention is paid to safety issues, both domestically and internationally. ” "In the process of transporting people and things in the mine, the drilling hoist, as a very important conveying tool, must have a certain number.
Therefore, in the mining process of a mineral deposit, the number of drilling hoists may reach dozens or even hundreds. ” "In particular, the underground conditions and working environment are harsher and more difficult than on the surface.
Therefore, in order to ensure the safety of personnel, there are often two or three drilling hoists, working at the same time" What Zhao Guoyang said, not only Zhao Siyan, but even Li Zhaohe had never heard of it at all.
When Zhao Guoyang said that he wanted to engage in drilling hoist, he did not tell him the details of market demand, but only told him that after the production of this kind of machinery, it will definitely not worry about sales.
Although he trusts Zhao Guoyang himself very much, after all, there is no basis for his words, and Li Zhaohe is a little uncertain about whether this mining equipment can achieve good results.
At this time, after listening to Zhao Guoyang's detailed explanation, the last trace of concern in Li Zhaohe's heart disappeared.
As for Zhao Siyan, she also looked suddenly enlightened.
She stroked the hair in front of her forehead, and gently bowed her head: "Well, according to that, this drilling hoist is really an indispensable equipment in mining activities, so we don't need to worry too much about the problem of sales."
Zhao Guoyang said "um" and said: "You can rest assured of this Siyan, the reason why I chose this drilling hoist was as the first flagship product of our SS company, the first thing to consider was the market demand." ” "If I hadn't had faith in this product, I wouldn't have been so determined to choose it as the main feature."
Zhao Siyan sighed, as if she remembered something.
She tilted her head to look at Zhao Guoyang and said, "Hearing what you say, Chairman, I have another question."
Zhao Guoyang shrugged his shoulders and made an expression of "but it's okay to say".
"My question is, since the market demand for drilling hoists is very large, why haven't I heard of any manufacturer producing this kind of machinery in China?"
Zhao Siyan frowned slightly and said: "But according to the drilling hoist design theory you proposed, it doesn't seem to be complicated, why":
