The Rise of Heavy Industry 1980

Zhou Dajiang worked until about 10 o'clock in the evening before leaving the unit and going home.

Maybe I hadn't worked overtime for too long, and I felt back pain on the way home, but I had a smile on my face.

After arriving home, the daughter-in-law had a quarrel with Zhou Dajiang, usually Zhou Dajiang would buy the vegetables after work, and the three of them had dinner together, but today they didn't even notice it, and it was so late, which is really infuriating.

The daughter-in-law complained a lot, but Zhou Dajiang not only did not refute, but still had a smile on his face.

"Daughter-in-law, do you know, today, I suddenly had the feeling of being young!" Zhou Dajiang said coldly.

The daughter-in-law was stunned at first, and then scolded with a red face: "What do you think, the old ...... is not serious

" Zhou Dajiang said busily: "The work I said, the state at work...... I really miss the feeling of having to finish it even if I work overtime!" The

daughter-in-law of the "......" was taken aback, isn't the man crazy?

Early the next morning, Zhou Dajiang came to the office, and after breakfast, he did not return to his seat, but went directly to the conference room where Wang Chaoyang and Zhang Miaomiao were.

When she entered the door, Zhang Miaomiao was looking down to read a book, and Wang Chaoyang was dozing off.

"I finished reviewing yesterday's drawings, which is very good!" Zhou Dajiang said.

"The trial is over?" Zhang Miaomiao was startled. Reviewing drawings often takes longer than drawings, so how can it be completed so quickly?"

Zhou Dajiang explained simply, and said: "The drawings are very good overall, but there are a few problems that I need to confirm with you individually."

Zhang Miaomiao stabbed Wang Chaoyang, who was in high spirits, rubbed his eyes and said, "Director Zhou, please speak."

Zhou Dajiang said: "The first point, why is the capacity of the bucket designed to be 2.5 tons? Is this your mistake? Because the original design capacity of this excavator is 2 tons.

Wang Chaoyang returned to the table again after hearing half of it, and when Zhou Dajiang finished speaking, he said casually: "Miao Miao explains."

Zhang Miaomiao explained: "This is a problem found in the capacity calculation. We found that the original design parameters of the excavator were sufficient for the strength of the main boom and beam, and the thrust of the main hydraulic cylinder was also redundant, so it was not a problem to increase the capacity from 2 tons to 2.5 tons. "

Then have you considered the shock load?" Zhou Dajiang asked.

"Considered, it is checked according to the impact coefficient of 1.5 times. "

What about the counterweight?" Zhou Dajiang asked.

"This is also taken into account, and the coefficient is 1.8. We looked at the data of the previous design and found that the counterweight coefficient was 2.5, which felt redundant, and 1.8 was enough for a mechanism like the counterweight that did not need to be moved.

"One more problem...... I don't remember exactly, but I wrote it in a notebook, so I'll check it later. Then Zhou Dajiang began to flip through the book. The questions in the book are listed one by one, and it can be seen that these are the effects of Zhou Dajiang's overtime work last night.

Along with Zhou Dajiang, there are also a few people in Xiaosun.

Zhou Dajiang searched for the contents from the notebook page by page, which surprised Zhou Dajiang's companions. They had never seen Zhou Dajiang so serious about a project.

Is this sun coming out of the west

......?" I want to ask if you have considered the full load speed of the excavator?" Zhou Dajiang asked again, "The increase in the capacity of the bucket not only needs to consider the transmission design of the bucket, but also considers the bearing capacity of the excavator itself, if the bearing capacity of the vehicle body is not enough, it will lead to the full load speed will be affected." "

Considered. Zhang Miaomiao said firmly.

"You're not kidding, are you?" Zhou Dajiang said with great skepticism. Checking the full load speed of the car body part through the full load weight of the bucket is no longer something that can be solved by general parts suppliers, but should be calculated by the system engineers of Longyuan Heavy Industries.

"Here's the check calculation, you can take a look. Zhang Miaomiao took out a notebook from the thick stack of papyrus paper in her hand, opened it to a page in the middle, and handed it to Zhou Dajiang.

Zhou Dajiang only looked at it a few times and didn't continue to look at it, which made the expert know if there was one as soon as he made a move, and he was already convinced that Zhang Miaomiao's words were true.

What was left for Zhou Dajiang was a deeper shock.

The supplier who designed the bucket has checked the walking speed of the whole vehicle at full load, and this matter is told to others, so that no one will believe it.

Next, Zhou Dajiang asked a few more questions one after another, but most of Zhang Miaomiao could answer them on the spot. Zhou Dajiang flipped through the small notebook he used to record the problem points until the end, and finally couldn't help but take a deep breath, and shook his head while looking at Zhang Miaomiao and Wang Chaoyang: "The future is terrifying, it's really terrifying...... It is simply an incompleteness to complete such a complex design work in such a short time, but the miracle has been completed by you, and it has been done very well!"

Zhang Miaomiao was praised and blushed a little, and said: "What is the result of the audit?"

Zhou Dajiang smiled: "Of course! Of course, the details of individual places still have to be changed."

Zhang Miaomiao was very happy: "That's not a problem, I can change it now!" As she spoke, Zhang Miaomiao

had already begun to revise the drawings. Drawings are drawn with pencil and need to be revised with an eraser. In order to accurately erase and correct, Zhang Miaomiao deliberately cut the eraser into a pointed shape, so that pinching the eraser can be more accurate, and it will not leave too modified stains after the correction.

In the past, after explaining the problem, Zhou Dajiang would leave directly, and he would prefer to drink tea and read the newspaper at this time. But after ending the conversation this time, Zhou Dajiang did not leave, but stood aside and watched Zhang Miaomiao revise. Because he was attracted by the beauty of the drawings from last night's review, this kind of beauty that only engineers can appreciate is incomparable!

Zhou Dajiang stood like this, Zhang Miaomiao was fine, but he was bitter for the companions of Longyuan Heavy Industry. The director stays here, and the others are embarrassed to leave? The director is standing, and the others are embarrassed to sit

?" "What's wrong with Director Zhou?" "What's wrong with Director Zhou?" "This isn't Director Zhou's usual style, why don't you drink tea and smoke cigarettes when you have this time

?" "Is there any other hidden secret?" This beautiful girl who draws pictures shouldn't be Director

Zhou's distant niece, otherwise how could she be so popular. "

......

In short, the others were slandered in their hearts, but Director Zhou didn't speak, and they could only hold it in their hearts.

The only alternative in the conference room was Wang Chaoyang.

Zhang Miaomiao was seriously changing the map, Director Zhou and the others were watching seriously, only Wang Chaoyang was there with a lot of anger, his head was like a chicken pecking rice in the first ten minutes, and his eyes couldn't open for the next ten minutes, and in the end, he simply lay on the table and went with Meng Zhougong.

An hour later, Zhang Miaomiao finished redrawing the map.

Zhou Dajiang read it again, said "yes", and left with the picture. After his review is completed, he needs to report to his superiors, and after the superiors approve it, the design plan of the Red Star Factory can be officially adopted.
