King of Industry

Following in the footsteps of Gu Shunzhong and Xiao Zhifeng, Zhao Guoyang and his party came to the finished product warehouse of Jinniu Machinery Manufacturing Factory.

Seeing the two factory managers bringing people over, the person in charge of the warehouse trotted over to lead the way.

Xiao Liu, let's go to see the mine hoist imported from South Korea, so you and the people below don't have to follow. Xiao Zhifeng waved his hand to the person in charge.

Yes yes yes... Mr. Gu, Director Xiao, those mine hoists are all on the east side of the warehouse. You two can see them after entering the door and turning left!

A group of people filed in, and after entering the warehouse, Xiao Liu, the warehouse manager, had already turned on the light switch behind them.

Gu Shunzhong was quite satisfied with this knowledgeable fellow, so he nodded slightly immediately.

Everyone turned to the left road and walked for less than three minutes. Dozens of brand-new mine hoists appeared in front of everyone.

Zhao Guoyang recognized the types of these devices at the first sight - multi-rope friction hoists.

This is the same type as the first mine hoist of the SMS company, and it is also the mainstream mine hoist used in international and domestic iron mines and coal mines.

After seeing the mine hoist in front of him, Gu Shunzhong's confidence returned.

He smiled and made a please gesture, leading Zhao Guoyang and the others to approach these devices at close range.

Mr. Zhao, look, this is the mine hoist that our factory just imported from the 'Hyundai Heavy Industries Group'.

Turning his head to look at Xiao Zhifeng, Gu Shunzhong gave him a wink and said, Old Xiao, please introduce the structure of these devices to Mr. Zhao and all distinguished guests!

Xiao Zhifeng nodded hurriedly, and began to explain everything.

Mr. Zhao, distinguished guests, this mine hoist is the so-called multi-rope friction hoist. Its main components include main shaft, capstan wheel, main bearing, groove device, reducer, depth indicator, Brakes and guide wheels, etc.”

Well, we've all heard of these before. Multi-rope friction hoist, how many construction machinery factories in our country can produce it?

Liu Yan said casually.

When Xiao Zhifeng heard this, he was very happy: Miss Liu is right. At present, there are probably three or four companies in China that can produce multi-rope friction hoists. Wuyi Heavy Industry, Pengcheng Construction Machinery Group Co., Ltd. The two giants are among them.

but……

Seeing Xiao Zhifeng deliberately paused, Zhao Guoyang pretended to be impatient and said: But what? Director Xiao, you mean that your imported products are better than Wuyi Heavy Industry and Pengcheng Construction Machinery Group Corporation? ?”

Xiao Zhifeng smiled slightly, and said slowly: Mr. Zhao, who is strong and who is weak, you can't listen to what our family has to say, right? So, let me talk about the advantages of our imported mine hoist!

All ears! Zhao Guoyang's eyes lit up, and he nodded repeatedly.

First of all, let's talk about the small aspects.

Xiao Zhifeng touched his nose, and said slowly: Generally speaking, the capstan of a mine hoist is the key to its movement. The importance of the friction lining with rope grooves on the surface of the capstan is self-evident. .”

Zhao Guoyang is naturally very clear about what Xiao Zhifeng said.

Not to mention him, the three postgraduate students of Capital University at the scene knew this well, not to mention Zhao Siyan, who is the head of the product research and development department.

Of course, because of the need to act, although everyone knew the situation very well, they didn't show the slightest expression on their faces. They all put on a serious look and listened to Director Xiao's explanation.

With Zhao Guoyang and the others paying such attention, Xiao Zhifeng felt a little complacent.

He puffed up his chest and said: Obviously, this friction lining should have a high friction coefficient, wear resistance, and pressure resistance. The quality of its material directly affects the production capacity, work safety and application of the hoist. scope.

At present, in the same type of domestic products, polyvinyl chloride or butyl rubber is used more as a gasket material.

Although these materials have good mechanical properties, they are not so durable in terms of wear resistance. At least, they are not the most reliable.

And the friction lining used on our imported mine hoist is made of polyurethane rubber. This material is not widely used in China. Mr. Zhao, you may not have heard of it.

Listening to this director Xiao's eloquent talk, Zhao Guoyang was secretly amused.

Speaking of materials, there are Liu Yan and Tang Wanru, two top students in the material department, so what's so great about this polyurethane rubber material.

You know, the graduate thesis of the two of them is about the replacement material of polyvinyl chloride.

Among them, polyurethane rubber material is also one of the preferred alternatives.

Of course, at this moment, Liu Yan and Tang Wanru could only pretend to be educated, watching Director Xiao pretend to be an elephant.

After talking about the material of the friction lining, Xiao Zhifeng set his sights on a brand new device of the mine hoist.

Mr. Zhao, you must have been to other construction machinery factories before, and you have seen many mine hoist products, right? But you may not see this device in China.

Following the direction of Xiao Zhifeng's finger, Zhao Guoyang and Liu Yan turned their eyes to the console of the mine hoist one after another.

A device similar to a scale is placed there abruptly.

The company's own SMS company does not have this device, whether it is Zhao Siyan, Liu Yan, Tang Wanru, etc., all showed curiosity.

As for Zhao Guoyang, of course it is impossible for him not to know what it is.

Well, is this some kind of automatic zero-adjustment device? When I went to England to participate in an exhibition of construction machinery products, I saw this device on a mine hoist from JCB!

After Zhao Guoyang said these words, Gu Shunzhong and Xiao Zhifeng looked at each other in astonishment.

Although they believed in Zhao Guoyang's status as a rich second generation before, but the other party had the money to go to England to participate in the exhibition of construction machinery products in Lao Shizi, his status as a local tyrant was definitely worthy of the name.

It's no wonder that these two are so dumbfounded. You must know that in the early 1990s, the cost of going abroad was at least tens of thousands of yuan, which was a sky-high price for many families.

Although because of the reform and opening up, the 10,000-yuan household has gradually become less intimidating.

But casually spending tens of thousands of yuan to go abroad to participate in exhibitions, such a family is definitely either rich or expensive.

After thinking about this, Xiao Zhifeng didn't dare to take it any longer, so he could only explain with a smile: Mr. Zhao is really well-informed. That's right, this is the difference between our imported mine hoist and domestic products. Another great innovation of the company - the automatic zero adjustment device.

Due to the inevitable creep and slip between the wire rope and the capstan pad, the depth indicator deviates from the zero position when parking, so it is very necessary to equip an automatic zero adjustment device to make the pointer automatically point to the zero position during each stop...

After Xiao Zhifeng stopped pretending to be reserved, the speed of introduction accelerated a lot.

Pointing to some on the mine hoist, he explained from time to time: This is the groove device, which is used for turning the rope groove, keeping the diameter consistent, which is conducive to the uniform tension of each wire rope.

This is a spring base reducer, which can greatly reduce the vibration of the machine.

While the director Xiao was teaching everyone about the mine hoist, Zhao Guoyang focused on the mechanism of the mine hoist itself.

Because he is proficient in South Korean characters, he can fully understand the operating instructions and product introductions on this mine hoist.

In the product introduction, one of the biggest advantages of this mine hoist was mentioned, but the director Xiao did not realize it.

The mine hoist of Hyundai Heavy Industries Group is a built-in friction hoist.

Its structural principle is that the working machine and the driving machine are combined into one and integrated with microelectronics technology and information technology. Its characteristic is that the motor is installed inside the reel or friction wheel.

This integrated electromechanical whole is both a working machine and a driving machine. Convenience comes second, and the most important thing is that the conversion of power is omitted, which greatly improves the efficiency.

Also, as an electric motor, it differs from conventional construction.

This kind of built-in friction hoist does not have the stator outside and the rotor inside, but just the opposite.

Speaking of which, the built-in hoist started production as early as 1988.

The world's first built-in hoist was put into operation in Shaft No. 7 of Neue Rumberg in the Germanhaus Arden Mine.

This mine hoist of Hyundai Heavy Industries Group is undoubtedly a plagiarized Germanic idea in many aspects, but this does not deny that it is a relatively excellent mine hoist.

After some observations, Zhao Guoyang has a clear idea of ​​the general situation of this mine hoist.

Compared with the products of its own SMS company, it still has certain advantages.

First of all, the built-in structure is beyond the reach of our own products.

However, after seeing the maximum static tension and maximum lifting angle of this mine hoist, Zhao Guoyang gradually let go of his worries.

Undoubtedly, in terms of the two most important technical parameters of the mine hoist, the products of its own SMS company are undoubtedly more competitive.

As for the benefits of the built-in structure, although it is obvious, it is not enough to completely crush the traditional structure.

Its stability is still unknown until it is tested.

In particular, this built-in structure can be seen at a glance as the Germanic imitation of Hyundai Heavy Industries Group, and there will definitely be flaws in terms of maturity.

In this case, if one's own product competes with it, it should not be too disadvantaged.

Not to mention if factors such as finished products and prices are included.
