Chapter 1351 Mechanical Research Institute

  Qu Mao, the director of the Outlying Island Institute of Power, Bi Sheng, Yan Qisheng, and their team members, led by Kong Ming, walked into the simple gate of the Outlying Island Institute of Mechanical Engineering.

  In fact, the Mechanical Research Institute is indeed a bit rudimentary. After entering the simple gate, there are only four four-story reinforced concrete buildings, and there are six seven-story reinforced concrete buildings under construction behind it.

   Obviously, even though there are only four four-story reinforced concrete buildings, they still look deserted and there are not many people.

Kong Ming waved his goose feather fan and said to Qu Mao with a smile: "My lord, I once heard from the maid in the lord's cabin that you are very disgusted and disgusted with climbing tall buildings, and you have expressed dissatisfaction with your bedroom on the fourth floor in the lord's cabin many times." satisfy.

  So although there are only 12 researchers in the Mechanical Research Institute, the subordinates have arranged 10 researchers to study the automatic lifting device..."

   Qu Mao was stunned for a moment, and asked, "Kong Ming, what is an automatic raising device?"

  Kong Ming led a group of people around a four-story reinforced concrete building, pointed to the back of the building, and said, "Master, please look, this is the experimental site for the automatic raising device."

   Qu Mao looked up along Kong Ming's finger, and was instantly happy.

The so-called automatic lifting device is nothing more than a two-meter-square wooden cabinet on the top, tied with a rope at the top, and two ropes go straight to the top of the four-story reinforced concrete building. There seems to be a winch on the side, and the top seems to be There is a pulley, and Qu Mao can see clearly even without taking out the telescope.

  Once the square cabinet needs to be lifted up, two people underneath will turn the winch, take up the rope, and the square cabinet will be lifted up by the rope.

  This is the same function as the elevator in another world, but here it uses human power, but in another world it uses electricity or other power.

  After a moment of joy in his heart, Qu Mao smiled from the bottom of his heart. Now that Kong Ming has started to study the automatic lifting device, will the elevator be far away?

   Qu Mao, who has been in the front line of industrial and technological development for several years in the Holy Land of King Yi, has deeply realized that all technological innovations start from the initial solution of a practical application problem.

   Wanting to understand this, Qu Mao carefully recalled the knowledge about elevators in another world, but after thinking for a long time, he only thought of the knowledge points of fixed pulleys and movable pulleys, and he couldn't think of specific and more detailed things at all.

So seeing Kong Ming's introduction, he almost asked two researchers to demonstrate to Qu Mao by twisting the turntable. Qu Mao hurriedly waved his hand to interrupt Kong Ming and said, "Kong Ming, don't bother to demonstrate, I'm afraid you are in the wooden box. The heavier the load, the harder it is for the man below to turn the capstan, right?"

Kong Ming shook his goose feather fan and said: "Yes, my lord, my subordinates and researchers are working hard to find a way to solve this problem. If the slideway is smoother and the resistance is smaller, it can indeed save a little effort, but it's not easy to get down. The speed of the box is not controlled.

  The subordinates are also considering whether the gear set can be applied to this lifting device..."

   Qu Mao shook his head and said: "You can take us to visit the Mechanical Research Institute and continue to introduce the ongoing projects of the Mechanical Research Institute.

After our visit, you find a meeting room, and I will slowly explain to you some knowledge about the automatic lifting device. Of course, I don’t know much about it, but I have seen this kind of device before and know some simple principles... "

Kong Ming's eyes lit up, and he said, "My lord, what's so interesting about the Mechanical Research Institute? That is, there are 10 researchers in an automatic lifting device project, and there are 2 researchers in a gear set research and development project. The subordinates are still waiting for more than one researcher." There will be a dual selection meeting for college graduates in a month, and then another batch of fresh graduates will be recruited.

  Now there are only these two projects, and there are only a few houses, so there is nothing to see.

  Let's go to the conference room to discuss your guidance, sir. The subordinates think this matter is more important. "

  Bi Sheng and Yan Qisheng also came together, constantly urging Qu Mao to give up visiting the Mechanical Research Institute, and instead went to the conference room to discuss the technology of the automatic lifting device.

   Qu Mao spread his hands helplessly, and said: "Actually, there is nothing to discuss, it is nothing more than a movable pulley and a fixed pulley, forming a pulley block to reduce the force required for lifting..."

   "This is already very important, my lord, hurry up!" Kong Ming had already inserted the goose feather fan in his belt, and was free to push Qu Mao to walk.

   Qu Mao had no choice but to be surrounded by a group of researchers and entered the conference room on the second floor of the nearest four-story reinforced concrete building. Kong Ming had already summoned all 12 researchers from the Mechanical Research Institute to the conference room.

   Glancing at the blackboard in the conference room, Qu Mao had no choice but to pick up a piece of chalk and start his teaching activities.

Qu Mao himself didn't know much about it, so he could only draw a schematic diagram of the fixed pulley and the movable pulley, and briefly introduce the functions of the fixed pulley and the movable pulley, especially the content that the movable pulley can save half the effort, so that Kong Ming and the researchers of the Institute of Unloading one light.

After sketching out a few simple schematic diagrams, Qu Mao said: "Kong Ming, experts from the Institute of Mechanical Engineering, I just remember that the pulley that moves with the weight we need to lift is called a moving pulley. Pulleys are called fixed pulleys.

  Each set of movable pulleys should be able to save half of the force, but the movable pulley must also be combined with the fixed pulley, otherwise it will not move with the object we need to lift.

  The specific operation mechanism requires you to repeatedly experiment and verify. You can study it first, and then install it on the device you are currently testing. "

Kong Ming looked at the diagram that Qu Mao had drawn on the blackboard in front of the meeting room, and kept drawing them in his notebook. As expected of a talented person, Qu Mao spoke for less than half an hour, and Kong Ming wrote and drew in his notebook faster and faster.

  Finally, before Qu Mao finished speaking, Kong Ming jumped up and said, "My lord, my subordinates may already know the principle, but further experiments are needed to verify it...

  If this thing can be developed, we only need to set up a bayonet on each floor, and we can easily send people and goods to the floor we want.

  With this device, adults don't need to worry about climbing stairs. "

   Qu Mao smiled and said: "You can do it according to mechanical power first, and then study the replacement of human power with steam power, internal combustion engine power or other power.

  Of course, Kong Ming, you don’t have to stay in the mechanical research institute all the time. You have to go to various universities when you have time to pay attention to the teaching and research of electricity. "

  Kong Ming said: "Yes, my lord! After finishing the automatic lifting device, my subordinates will go to supervise the electricity teaching activities in various universities."
