Jiang Feng looked at it and shook his head silently, this management system is indeed a bit lax, and it is easy to have an accident! The shearer is piled up in the raw coal warehouse, and the damage is a bit serious.

[Rotary excavator] a round row of cutter heads, smashed to serious deformation and fracture, the collapse must be not small, the mechanical arm is broken and damaged in many places, and the material needs to be repaired.

"HOW BIG OF A ROCK DOES IT TAKE TO ALMOST SCRAP THE CROSS-SECTION [30×35CM] OF THE ROBOTIC ARM WITH A CROSS-SECTION?"

Coal mines shouldn't have collapsed like this, right?

Wei Da took out the [auxiliary detector] and took a photo, then measured the hardness of the robotic arm, and replied: "It should be about three tons of hard rock, conical type." ”

It seems that not only does it need to be welded, but it may also have to replace some materials and strengthen the shell of the robotic arm, but fortunately it brings a lot of reinforced steel and titanium alloy steel.

"Boss, there are a total of 25 damages, and it will take at least half a day to repair, 300,000 is a bit low!" Wei Er replied after a comprehensive inspection, and he was very responsible for his advice:

"The material cost can be added to 100,000 yuan. ”

"Yes, that's right, you have to add material fees!"

Jiang Feng raised his eyebrows, nodded with a smile, his own reinforced steel/titanium alloy/repair glue is so expensive, of course, it should add additional material costs, barely 100,000 yuan.

After speaking, he called Section Chief Wang---

Wang Bingqing has also gone to work, and is busy dealing with the logistics of the coal mine, with a lot of, and he is in charge of the food, drink, tools, water and electricity of hundreds of workers.

However, the most important thing at present is to repair the imported shearer, and when he heard that Jiang Feng was coming, he immediately rushed to the large warehouse of the coal mine to greet everyone---

"Hello Mr. Jiang! Wang Bingqing, the contemptible man, is the logistics section chief of Xinsheng Coal Mine, welcome, welcome, these people..."

"Hello Section Chief Wang! This is my person, a mechanical maintenance technical expert, Luo Honda/Wei Da/Wei Er..."

Wang Bingqing said: "Welcome experts!"

Mercenaries: "Thank you, Section Chief Wang!"

Luo Honda sneered: "Hello Section Chief Wang!" He complained in his heart that Jiang Feng was blind and introduced, and he was also an expert? I felt very embarrassed, he was purely here to make soy sauce.

After some politeness, the two sides got to the point, Wang Bingqing introduced the collapse accident, which was consistent with Wei Da's speculation! Jiang Feng made it clear that the damage was serious and gave specific data--

1. Rotary excavator knife breaking/deformation ×5

2. Robotic arm breakage/rupture×4

3. Wire breakage/short circuit burning×3

4. Conveyor belt deformation/motor damage×3

5. Failure of supporting lighting system ×1

6. Other injuries ×9

"At present, there are two maintenance plans, the first is a simple maintenance standard, with a maintenance fee of 300,000 yuan, which can basically solve the problem, but the warranty period is only one year!"

"Secondly, it can be fully repaired, to ensure that it can meet the factory standards, in principle, the warranty is two years, and the maintenance quality problems are free of charge, and the cost is 400,000!"

Jiang Feng took the tablet and showed him the inspection report issued by Wei Da, and Wang Bingqing looked at this detailed inspection report in surprise [Xinsheng Coal Mine Shearer V1].

Clearly, all the damage, maintenance plans, accident simulation diagrams, damage data, and mechanical performance data were displayed, which made Section Chief Wang very confused...

Issue date 2017-8-20/8:20

"It's... It's really... Since Mr. Jiang has already said so, I will immediately notify the company and ask the senior management how to repair it, please wait a few minutes. ”

Jiang Feng smiled: "No problem, no hurry!"

Now the coal mining industry is sluggish, profits are far less than as high as before, and hundreds of thousands of dollars to repair equipment have to ask the high-level for instructions, which shows that there is serious overcapacity.

Jiang Feng's current routine is to give others two levels to choose from every time, simple repair// comprehensive repair, usually choose to repair well, who wants to spend money to repair half?

Sure enough, Xinsheng Coal Mine is also on the set!

The emaciated camel is bigger than the horse, and the senior management of Xinsheng Coal Mine quickly decided to choose the 40w comprehensive repair; Wei Dawei II and Wei San immediately started construction, welding/gluing/resetting...

The deformed [rotary excavator] cutter head is burned red by them with [metal jet blowtorch], and the hammer is manually [reset], and by the way, the performance of the tool can also be strengthened, and the crack is laser welded.

The damage of the robotic arm is more serious, the super welder is more suitable for this kind of crack, Wei Si is responsible for welding, Luo Honda helps remove the rust on the surface, and Jiang Feng will repair the wires.

Super welding machine, high-frequency pulse electromagnetic gun, metal jet blowtorch, laser welding machine, laser rust removal machine, etc., all kinds of advanced equipment, so that Luo Honda was stunned.

I can't use it, but I look amazing...

The maintenance soldier technology is against the sky, and the cutter head can be easily reset accurately with a hammer; the welding speed is explosive, and the welding is completed in minutes, and there are no welding marks.

What kind of welding, will there be no weld marks?

Even if the foreign technology is not so advanced, I'm afraid it is not so advanced, right? [Laser derusting machine] The efficiency is also quite awesome, and the power consumption does not seem to be large...

Because the machine is not hot, the size is small, and there is no noise vibration at all, Luo Honda wondered, where did you buy these devices?

He helped out while filming videos.

Jiang Feng didn't intend to stop it, posting on Moments was just the right thing to spread his fame and let more people know, but some techniques couldn't be leaked, for fear of arousing suspicion.

Luo Honda also has it in his own heart.

Unconsciously, the time was almost noon, and the mechanical arm was finally repaired!

Wang Bingqing came over a few times halfway, and there were also logistics reception beauties in the coal mine, helping to serve tea and water, and watching them use their artifacts, they almost burst their eyes.

"Tsk~ This speed is no one!"

"Needless to say, technology is everything!"

Wei Da: "Boss, it's okay to check." ”

Jiang Feng nodded, looked at the time and replied: "Then let Lao Wang come to accept it! Let's not include the installation, these things will be handled by themselves, at most we will take a look." ”

"Cut~~ What is there to see in the coal mine?"

Luo Hontian looked bored, but Jiang Feng was very interested in the structure of the coal mine, and his father went to dig coal!

I used to hear that when you enter from the main roadway, there is a coal mining channel a few hundred meters behind, and the height is reduced from a few meters to only about half a meter.

Anyway, he really wanted to go in and see what it would look like...

Within two minutes, Lao Wang came over and threw himself on Jiang Feng's admiration, and the deputy general manager, safety technology chief, and finance chief of the coal mine also came to accept the inspection.

Looking at the brand-new [Engineering Yellow] fully automatic imported shearer, there are no flaws, the system operation control is working normally, and Dafang has passed the acceptance.

The Finance Section paid 400,000 for repairs!

Then, inviting Jiang Feng and them to dinner, the attitude was very enthusiastic and could not refuse, so they could only go together; the leaders of the coal mine complimented all kinds of relationships and wanted to make friends with Jiang Feng.

This is the most awesome technical boss~

As a coal mine leader, you never know what you might encounter in the future, there are too many coal mine equipment, and there are often various failures, and it is good to know the experts!

After eating, Jiang Feng proposed to go down the mine, just take a stroll in the main roadway, and take a look at the inside of the coal mine; this is not a big deal, and the deputy general manager agreed.

Moreover, he personally took Jiang Feng/Wei Da/Wei Er, as well as Wang Bingqing, the chief of the safety technology section and the chief of the logistics section, and everyone went down the well together, and they didn't have to change their clothes...

This management system 666, eat jujube pills!

As a result, Jiang Feng really found a big problem!
