Chapter 198 Hoisting!

Principal Qi Meige was extremely happy with this result, and after so many years, he finally raised his eyebrows.

After the results of the joint entrance examination were announced to the public, olive branches from colleges and universities across the country were sent to Peking No. [-] Middle School in the form of telegrams like snowflakes.

National Peking University, National Beijing Normal University, National Jiaotong University, National Zhejiang University, and even the transcendent existence in the national university system, Central University, all sent admission invitation letters.

In addition, there is also the king of the church universities, Yenching University, which also sent an invitation letter to Beiping No. [-] Middle School.

The conditions offered by various universities are extremely generous, almost to the extreme. As long as you accept them and go through the admission procedures immediately, not only will all tuition fees be waived during the university study period, but also fixed annual scholarships will be given.

As the richest university in the country, Yenching University offers an annual 1000 Ocean Scholarship and conditions for employment in the university after graduation.

National Central University does not have the salary of working in the school after graduation. The scholarship is 800 fiat per year. National Peking University offers post-graduation teaching assistant and 500 fiat scholarship per year. National Jiaotong University and National Zhejiang University each give corresponding treatment.

I have to say that this kind of treatment is extremely generous, which makes countless students jealous and envious, but considering Yu Hua's joint entrance examination results, he can't say anything.

For students, grades are everything.

Full marks in seven subjects.

This is an achievement that countless high school students in Peiping could not even imagine.

However, Yu Hua, who was staying in Liucun, and after learning about the olive branches of colleges and universities through Lin Wan, rejected them all, and once again devoted himself to the tense and busy process of manufacturing the Seven Pagodas of the Yu Family.

Olive branches from colleges and universities around the world are acceptable, but not necessary.

University, he just wants to go to Tsinghua.
For him, Tsinghua is the best solution at the current stage, no one.

The popularity of the Peiping joint entrance examination remains high. All kinds of things have become the talk of parents and teachers after dinner. Ordinary people are still running around for three meals a day. For the vast majority of people, what is Yu Hua, the champion of the joint entrance examination. It's far less important than filling the belly.

Baiyangdian, Liucun, experimental site.

At dawn, at [-]:[-], there is a whitish tinge of white on the distant horizon.

The lights in the experimental site were bright, and two core containers with metallic luster were lying on the ground. In three days, the welders who stayed up late to work had finished the No. [-] acid generator and the No. [-] denitrification tower, and transported the two core containers to the ground. placed in the experimental field.

The reason why the two core containers are lying on the ground is that they are waiting for the lifting device.

In the experimental site, there are four three-meter-high metal columns. The base is a newly built brick-concrete base, which is connected by screws. A thick steel beam is installed on the metal column. The front end of the steel beam is an electric hoist. The rear end of the beam is a thick stone bar.

This is a simple hoisting device similar to the gate railing structure of the later generations. Yu Hua designed and manufactured it based on the current technical level. The structure is simple, stable and reliable. It is placed at the four corners of the predetermined position of the container, and is used to hoist the core container with a weight of 9.5 tons.

In the experimental field, the No. [-] acid-forming tower lying on the ground is lying on the predetermined area. The top and the middle of the container are each wrapped with a steel rope. The middle steel rope is installed with four lifting rings, which are connected to four lifting devices, and the top is connected to a team. Workers, their role is to adjust the position and angle of the container from 'lying' to 'standing' after the core container is hoisted.

It sounds complicated, but it's actually quite complicated.

But no way.

In the era of no large-scale lifting engineering equipment, complexity is not important, what is important is whether it can be used.

Coincidentally, this installation method works.

Can be used, with a little original taste.

All the preparatory work before hoisting has been completed. More than [-] workers are holding the hemp rope connecting the top steel rope in their hands. The four corners of the preset area are ready. Four hoisting groups have undergone simple training. rings.

Yu Hua, the elegant man, Liu Wei, and Lin Wan stood on the right side of the experimental field base, quietly watching the first core container. The on-site hoisting person gave instructions to carry out hoisting operations. Then, the sound of the electric hoist doing work came out, lying on the ground. The core container of the scorpion rose, leaving the ground where it had been lying for several days, suspended in the air, and its height gradually rose.

After reaching a height of three meters, the worker team received instructions, and more than 100 people began to pull the hemp rope, a horizontal force was generated, and the head of the core container in the horizontal state rose slowly, changing its posture, and when the inclination angle rose to [-] After a short time, a new password was issued, the workers' team stopped pulling the hemp rope, and the four hoisting teams controlled the railing lifting device to lower the height.

Soon, the core container in the tilted position slightly touched the ground, and the worker team pulled the twine again, causing the tilt angle to increase again.

After more than ten seconds, the entire core container was facing the sky at [-] degrees and was in a horizontally upright posture. The four hoisting teams lifted the container and the tank to a predetermined position.

After a few minutes.

"Boom!" With a slight dull sound, the core container weighing [-] tons landed precisely on the predetermined position of the experimental field.

"Success!" Seeing this scene, many workers made excited and joyful voices.

The person in charge of the hoisting and the four hoisting teams breathed a sigh of relief. Fortunately, nothing went wrong.

"This method doesn't look very good, but it's actually very useful. It solves the problem of hoisting and moving heavy objects." The elegant man smiled, clapped his hands, sent applause, and praised.

Lifting and moving heavy objects has always been a problem. People can carry one or two hundred kilograms of things on their backs, but they cannot carry five or six hundred kilograms of heavy objects to move. Can't move.

The railing-type lifting device looks simple, but it directly solves this problem.

Liu smiled and nodded, applauding the first-time comrades.

"Yu Hua, your method is really good." Lin Wan clapped her hands and said to Yu Hua with a smile on her Su Mei face.

"It's everyone's credit." Yu Hua smiled. He was not surprised that the core container was successfully hoisted. This method based on the lever principle has been mathematically verified. The mathematics told him that it was feasible, and Archimedes provided the principle.

As for the defects of this hoisting method, it is not important under the premise of 'usable'.

Safety?

Shabby?
original?

does not exist at all.

With the successful experience of the first collaborative hoisting operation, it is much easier to install the core container next, and he does not need to worry about it.

After watching the hoisting operation of the core container, Yu Hua and Lin Wan left Liu Village together, took a Buick car, and set off on the road to Peiping. Today is very important for the two of them. Yu Hua is going to Tsinghua University to take the entrance examination. Lin Wan wants to Going to Peking University to take the entrance examination, the time is [-] o'clock, and there is no delay.

On the road, the driver drove very fast, the co-pilot was Yang Xiu, and the housekeeper Liu and the elegant man stayed in Liu Village.
