I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Elevator?

Gong Shucan was taken aback for a moment, he had never heard of this name before.

In fact, Liu Tan was not sure.

The things he proposed in the past were basically based on the technological level of this era, and he basically threw aside things that were obviously impossible to produce in this era.

But through contact with the public loser, he felt that the elevator is basically between what can be done and what can't be done.

It can be said that it can be done because in large-scale fortifications, the transportation of materials has changed from manpower to mechanical assistance. Of course, this machine is basically something like a pulley.

But this is already a direction. If the elevator is driven by electricity, then there is a very simple problem in front of us, how to make it rise.

The main body of the lift can basically be regarded as a wooden or bamboo box.

In fact, bamboo can reduce the weight of the elevator itself, but bamboo is soft, and it is easy to feel insecure from the bottom to the top, and the softness under the feet may make people feel more scary.

On the wooden box that is more than one person tall, there are iron chains tied at the four corners, and then these iron chains and gears must be tightly meshed, and the wooden box will be brought up bit by bit through the rotation of the gears.

This is Liu Tan's initial idea, so the question arises, how to make this gear turn.

There are at least three people inside the wooden box, the weight is not light, and in order to minimize the uneasiness caused by the shaking when the elevator goes up, four iron chains are required to bear the load at the same time, which makes the design more effective than a single chain. It became difficult.

Liu Tan looked at Gong Shucan and said, "Can this be resolved?"

Gong Shucan looked at the picture drawn by His Royal Highness the King of the Northern Territory, touched his chin and said, "In this case, wouldn't it be enough to use the turning mechanism of the water wheel?"

Liu Tan pondered and said: "You mean to use the pulling force of the cow as the power of the elevator?"

Gong Shucan doesn't know what power is, but he still understands the meaning of the whole sentence. He drew a schematic diagram and said: "This mechanism is not difficult, but the requirements for iron chains are very high, so it must not appear." any problem."

Liu Tan asked, "Is the bull so strong?"

Gongshu smiled and said: "Your Highness, you are joking. An ox can even pull a water cart. Can three or four people plus a wooden box weigh more than a water cart?"

Liu Tan also thought about it: "In this case, in order to ensure safety, it is best not to use wood, but to use an iron winch."

Gong Shucan hesitated: "I'm afraid it's not easy to do."

Liu Tan waved his hand: "There is nothing difficult to do. You go back and design a model. If there is no problem, put it into use."

Of course, when this is put into use, it must be tested with other things at the beginning.

Others like to let the slaves go up the test, but Liu Tan couldn't bear it, it was more or less a human life, so he simply asked Gong Shucan to use pigs and sheep to test.

Anyway, even if something goes wrong, you can add another dish at night.

Before leaving, Gong Shucan asked, "Your Highness, do you have any requirements for the elevator?"

Liu Tan thought for a while and said, "You must be steady. It doesn't matter if you slow down, as long as you are steady."

Gong Shucan immediately said, "Okay!"

As soon as Gong Shucan left, Zhu Shanyi came back and said, "Your Highness, the road construction has been arranged."

Liu Tan nodded, because the place chosen by the water park is relatively remote, so there was no road leading to it before, so even if the pool has not been dug, the road must be made first, so that in the follow-up construction, there will be no roads. The flat cement road is also easy to transport.

Liu Tan didn't take this matter to heart at first, but he saw that Zhu Shanlian had a hesitant expression on his face after he finished speaking, so he couldn't help but said: "Just tell me what you think, don't let me guess." .”

Zhu Shanzhang was taken aback, of course he didn't dare to let Liu Tan guess his thoughts, and said hastily: "I just checked the length of the road that needs to be repaired, Your Highness...it is at least twenty miles from Changshou Palace to there. About, within a day, it may not be so easy to let His Majesty have fun and return to the Longevity Palace."

Liu Tan paused and couldn't help sighing.

Zhu Shanqian hurriedly asked: "This minister talks a lot, His Highness must have already had..."

"No." Liu Tan interrupted him and said, "I always felt that there was something wrong. If you don't tell me, I'm afraid I've forgotten."

He turned his head and patted Zhu Shanyi on the shoulder and said: "In the future, if you have anything to say, just say it, learn from Huo Xiang. If you don't tell me, how will I know what's wrong? Don't worry that I will be unhappy, as long as you are not in public Scold me, nothing else."

Zhu Shanzhang hurriedly said in panic, "I...I dare not."

Liu Tan said with a smile: "Don't be so cautious, it's been so long, when did I punish people indiscriminately?"

His words, Zhu Shanzhang, agreed. Not only did His Royal Highness not punish people indiscriminately, he did not violate the law and did not involve issues of principle, and basically he would turn a blind eye.

He is really a very reasonable and soft-hearted prince.

Zhu Shanyi had also heard about the deeds of other princes and kings from his mother. The more he thought about it, the more he seemed to understand why the emperor liked the king of the northern border so much—there were so many uneasy elders, brothers, and sons, and finally Who doesn't like to meet someone who not only saves worry but also brings happiness.

After Liu Tan reassured Zhu Shanzhang, he began to worry.

It must be too late to build another palace at the amusement park, and the distance is awkward, not too close, not far, and even if he can afford another palace, Chang'an will have something to say.

Those people probably wouldn't say that Liu Che was extravagant, but only that he was extravagant.

Of course, the most important thing is that there is no place that is particularly suitable for building a palace, because Zhu Shanyi specially chose a place with woods for the sake of a beautiful scenery and not so bare.

The number of places with trees in the entire northern border can be counted. This forest is dominated by elms and poplars. If it is beautiful, it is not good, but at least it is green and eye-catching, which is better than only grass when you look around. After all No matter how vast the grassland is, it may seem open-minded at first glance, but after a long time, it will become aesthetically tired.

Liu Tan looked at the forest, which was not considered small in size on the map, and Zhu Shanyi, who was beside him, whispered, "If it's not possible, we can set up the camp in advance."

camping?

Looking at the forest, Liu Tan suddenly had a flash of inspiration and said, "I think there is a way."

Zhu Shanqian looked at Liu Tan, who smiled slightly and said, "Since it's not easy to build a palace, let this forest become a palace."

Zhu Shan was at a loss: "Your Highness means..."

Liu Tan stretched out his hand and patted the table: "I want to build a tree house!"
