Nie Hongqi shook his head and said in a deep voice: "No one told the informant, it was Chief Liu Xiaojun who saw it himself." On that day, Captain Liu Xiao came to visit our Huaxing Industrial Park, and happened to meet Director Guo who transported the gantry milling machine and vertical lathe out, so he was curious and found our place. ”

"He must have wanted to move them all out!" Fu Xin said with a pout, he became more and more aware of Liu Xiaojun's banditry behavior and his deep friendship with him over the years.

"Yes...... Yes. Nie Hongqi replied hesitantly.

"At that time, it was Mo Li who dragged him and persuaded him for a long time before he stopped, and then dragged away one of our CNC machine tools, and he didn't pay, right?" Fu Xinyou guessed.

"Nope." Nie Hongqi shook his head and said, "At that time, Manager Mo just explained, and Head Liu gave up, but Head Liu said that he would negotiate with you when you came back." ”

"Didn't pay?"

"Didn't pay." Nie Hongqi nodded, "Head Liu said that when you come back, he will discuss the price of the machine tool with you." ”

"Affection has become his shield and talisman." Fu Xin said with emotion, "Okay, I know about this matter, I will go and talk to him, let's go, go and see our new headquarters building." ”

……

Walking into the newly built headquarters building that is being renovated, Fu Xin's eyes are not busy workers and painters, but rows of beds.

Seeing these beds, Nie Hongqi's face turned red and he wanted to explain, but Fu Xin immediately said, "Okay, no need to explain, I know what's going on!" It's also cold to live in tents outside now, so let the workers stay here for the time being! But after the decoration is done, they have to find another place. ”

"Okay, I remember." Although Nie Hongqi was a little strange in his heart, how Fu Xin was so clear, but he was in professional quality, and he would not think about the boss and ask why, it would be too reckless!

The headquarters of Huaxing Industrial Development Company was designed by Fu Xin himself, and it looks a bit like a hotel in later generations, or a mansion, or a large shopping mall, because the staircase is in the center of the hall, spiraling upward, except for the first floor, surrounded by corridors and rooms, and it does not seem to have a sense of fear because the floor is high.

As a landmark building in Xunyang, Huaxing Industrial Headquarters Building is thirteen floors high, yes, it is thirteen floors, and it is thirteen floors without a basement, perhaps in the eyes of foreigners, thirteen is a very unlucky number, it comes from religious allusions: Judas, who betrayed Jesus, is the thirteenth disciple of Jesus, but in his Fu Xin's eyes there is not so much exquisiteness.

He is new and does not believe in Christianity, thirteen is thirteen, he prefers this number, and he still has a soft spot. Because Fu Xin is more sensitive to prime numbers, in his previous life, he often turned on the sound to the volume of thirteen or seventeen when he watched TV.

A thirteen-storey building will naturally have a preparation, that is, an elevator, which is still a rarity in China, but if you want to buy it, it is not impossible to buy it, Siemens has it.

With the good relationship between Huaxing Industrial Development Company and Siemens, Huaxing Industrial Development Company has ordered a set of 13-storey passenger elevators in Siemens, which has been installed but not put into use.

Naturally, this elevator is not produced in China, and Siemens' elevator business has not yet entered the Chinese market. Why did Fu Xin want to go far and near, others didn't know, and they were very puzzled, but Fu Xin understood it very well in his heart.

This is actually a deal between Fu Xin and Siemens, Siemens wants to let his elevator business enter the Chinese market, but because Siemens' elevator business is different from Otis in the United States, Siemens' elevator business is not well-known in China.

Therefore, the significance of this cooperation is self-evident, Siemens wants to borrow the hand of Huaxing Industry to promote the reputation of his elevator business, so as to enter the Chinese market.

Hearing Nie Hongqi say that the elevator has not been used yet, Fu Xin is interested, so he naturally wants to experience it. Fu Xin's behavior, in Nie Hongqi's opinion, is curiosity, but in Fu Xin's heart, it is not like this, Fu Xin has his thoughts in his heart.

"It's been a long time since I've developed a new product, this elevator, why don't you also have a play!" Fu Xin thought to himself in his heart. In Fu Xin's heart, entering the elevator industry is indeed playing, Huaxing Industrial Development Company is to do 10,000 doors program-controlled exchange telephone such a large project, like the elevator project, he Fu Xin is really not very eye-catching.

If you do everything, you can only achieve nothing in the end, because you have no specialization, and if you don't specialize, then you are doomed to have no vitality in this enterprise, and when this wave of craze passes, it will tend to be flat. Don't think about eating fat in one go, everyone earns money together is the long-term way, and everyone is really good.

The working principle of the elevator is that the two ends of the traction rope are connected to the car and the counterweight respectively, wound on the traction wheel and the guide wheel, the traction motor drives the traction wheel to rotate after changing the speed through the reducer, and the traction force generated by the friction between the traction rope and the traction wheel realizes the lifting movement of the car and the counterweight, and achieves the purpose of transportation. It has a car that runs between at least two columns of rigid rails that are perpendicular or have an inclination angle of less than 115 degrees. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods.

……

It is divided into the machine room part, the hoistway and pit part, the car part, and the landing part.

……

Traction system: The main function of the traction system is to output and transmit power to make the elevator run. The traction system is mainly composed of a traction machine, a traction wire rope, a guide wheel and an anti-rope wheel.

Guiding system: The main function of the guiding system is to limit the freedom of movement of the car and the counterweight, so that the car and the counterweight can only be lifted and lowered along the guide rail. The guide system is mainly composed of guide rails, guide shoes and guide rail frames.

Car: The car is an elevator component that transports passengers and goods, and is the working part of the elevator. The car is composed of a car frame and a car body.

Door system: The main function of the door system is to seal the entrance to the landing and the entrance to the car. The door system consists of a car door, a landing door, a door opener, and a door lock device.

Weight balance system: The main function of the system is to balance the weight of the car relatively, so that the weight difference between the car and the counterweight can be kept within the limit in the elevator work, so as to ensure the normal traction transmission of the elevator. The system is mainly composed of counterweight and weight compensation devices.

……

Electric Traction System: The function of the electric traction system is to provide power and implement elevator speed control. The electric traction system is composed of a traction motor, a power supply system, a speed feedback device, a motor speed regulating device, etc.

Electrical control system: The main function of the electrical control system is to carry out longitudinal control and control of the operation of the elevator. The electrical control system is mainly composed of a longitudinal device, a position display device, a control panel, a leveling device, a layer selector, etc.

Safety protection system: to ensure the safe use of elevators, to prevent all accidents that endanger personal safety. It is composed of elevator speed limiter, safety gear, rope clamp, buffer, safety touch plate, floor door lock, elevator safety window, elevator overload limiting device, and limit switch device.

……

Elevator traction machine mainly includes permanent magnet synchronous traction machine and traditional asynchronous traction machine, traction machine is the heart of the elevator, after planetary gear transmission, helical gear transmission and worm gear transmission and other technologies after upgrading, at the end of the nineties of the last century, there was a permanent magnet synchronous traction machine.

……

In 1907, Otis installed two elevators at the Huizhong Hotel in Sea City. These 2 elevators are considered to be the earliest elevators used in China.

……

In 1935, Daxin Company, located at the intersection of Jingnan Road and Xizang Road in Haihai City, installed two two-part wheeled single-person escalators from Otis. The two escalators were installed between the paved mall and the 2nd and 2nd floors and the 3rd floor, facing the gate of Nanjing Road. These two escalators are believed to be the earliest escalators used in China.

……

In the winter of 1951, the party. The central government proposed to install a Chinese-made elevator in the capital [***], and the task was handed over to Jintian's private Congqingsheng Motor Factory. More than 4 months later, the first elevator designed and manufactured by Chinese engineers and technicians was born. The elevator has a load capacity of 1000kg, a speed of 0.70m/s, AC single speed, and manual control.

……

On December 28, 1952, the electrical repair office of the real estate company of Haicheng was established. The personnel are mainly composed of the personnel engaged in the elevator business in the sea city of Otis Company of the United States and Schindler Company of Switzerland and the personnel of some private manufacturers in China, mainly engaged in the installation, repair and maintenance of elevators, plumbing, motors and other housing equipment.

……

In 1952, Haicheng Jiaotong University set up a major in lifting and transportation machinery manufacturing, and also opened a special elevator course. In 1954, the lifting and transportation machinery manufacturing major of Haicheng Jiaotong University began to recruit graduate students, and elevator technology was one of the research directions.

On October 15, 1954, the Offshore City Huakaiji Elevator Hydroelectric and Iron Factory, which went bankrupt due to insolvency, was taken over by the Maritime City Heavy Industry Administration, and the name of the factory was set as the local state-owned Maritime City Elevator Manufacturing Factory.

In September 1955, Zhenye Elevator Hydropower Engineering Company was merged into the factory and named "Public-Private Partnership Sea City Elevator Factory".

At the end of 1956, the factory successfully trial-produced an AC two-speed signal control elevator with automatic leveling and automatic door opening.

……

In 1974, the mechanical industry standard JB816-74 "Elevator Technical Conditions" was released, which was China's early technical standard for the elevator industry.

……

On July 4, 1980, China Construction Machinery Corporation, Schindler Co., Ltd., and Xiangjiang Jardine Schindler (Far East) Co., Ltd. jointly established China Schindler Elevator Co., Ltd. This is the first joint venture in China's machinery industry since the reform and opening up. The joint venture includes the Haicheng Elevator Plant and the Jingcheng Elevator Factory. China's elevator industry has set off a boom in the introduction of foreign investment.

……

On December 1, 1984, Jintian Otis Elevator Co., Ltd., a joint venture between Jintian Elevator Company, China International Trust and Investment Corporation and Otis Elevator Company of the United States, was officially opened.

……

Trying to dig out the fragmentary knowledge about elevators in his mind, Fu Xin has noticed that Haicheng Jiaotong University, Haicheng Elevator Factory, and China's elevator industry have set off a boom in the introduction of foreign investment. A plan slowly took shape in Fu Xin's mind.
