Harbor Craftsman's Refining

The Bihai is in the sky, and the mountains on the Zhoushan Islands are winding up and down, like a group of running teenagers, leaping into the sea, carefully passing through several thousand tons of giant wheels, like a mighty son, exposing again on the sea on the distance, exposing again on the sea. Come to Dai Blue Body.

Senior engineer Li Guihao stood by the sea and watched the 10,000 tons of giant wheels approaching slowly. Several tens of meters high on the shore, such as red beasts, danced with huge cranes, and grabbed the container on the boat to the shore one by one. Li Guihao knows that this is the busiest port in the world, Ningbo Zhoushan Port, and has been in the world's first throne in the world for thirteen years, a year after his working age.

Help the company saving one million yuan

In 2010, since the entry of Zhejiang Harbor Group and Ningbo Zhoushan Port Group, Ningbo Beilun First Container Pier Co., Ltd. has been dealing with those red giant beasts, familiar with their "temper", inspections, maintenance, and maintenance to ensure that they are healthy and normally and normally Operation. From the appearance, the heavy crane can be divided into bridge cranes and dragon gates. They have a lot of cables and electrical components to ensure that they follow the driver's control. When running abnormal, Li Guihao quickly rushed to the scene, climbed up and down, and found the fault in the fastest time to solve the problem.

This is a job that requires experience and luck. These guys are huge in size. After the failure, the maintenance personnel should check multiple points. Some motor controllers need to connect to the computer to check whether the running status is normal. "Sometimes it is completely experienced, where the problem may be in the brain. Sometimes it is also lucky, and the point of the inspection is the failure point. In fact, I did not expect it." Senior maintenance personnel took one or two colleagues to the scene. If two or three equipment were broken at the same time, the maintenance resources would not be well coordinated. If the failure occurred at night, the maintenance staff climbed up and down, and there was a hidden safety hazard.

In 2016, the company's scale expanded, and the equipment was added, and the pain points of maintenance were even more prominent. Li Guihao organized the team to think about whether a set of information management systems can be studied, so that the maintenance personnel can sit in front of the office computer, and they can see the running status of the equipment. Li Guihuan's idea is not the air tower, because the equipment itself has operating monitoring systems, but because the design is not reasonable enough, lack of maintenance, frequent power off, the system computer often fails, and the monitoring system only runs on a single device. Check. What Li Guihao and the team are doing is to integrate the operation and monitoring system of five or 60 devices to a computer.

The mature application of 4G IoT also makes Li Guihao's idea easier to realize. "If the original traditional industrial network deployment is used, we must install some antennas at the highest equipment, and then pull down some communication cables, and finally gather to the electronic control room. The hardware installation process will be very long." And with the help of 4G networks, we only need Install a router on the device and connect to the company's public network, you can connect the background. The whole process only takes an hour. Li Guihao spent more than half a year and experimented on the two devices. He reported to the leader: the network is stable, and the development function can meet the needs. After collective discussions, everyone agreed to use the information management system for all equipment. "Just like 'WeChat', it is now a tool for us to use it." Li Guihao said, just sitting in front of the computer, you can see where the equipment is intuitively, which greatly improves the maintenance efficiency.

In addition to facilitating maintenance, Li Guihao said that like the "WeChat" applet, the equipment information management system can develop more functions. The outbreak of the new coronary pneumonia in 2020, the company's call for "cost control". Li Guihao and the team developed two functions on the existing system to help the company save more than one million yuan.

One is the oil and electricity monitoring system. After the device transfer venues such as Dragon Gate, the diesel engine needs to be turned off to timely access the power system settled by the venue to reduce energy consumption. This requires the driver to actively operate, and the situation of forgetting happens. After using the function of Li Guihao's team, the managers can monitor the oil consumption of the equipment and remind the driver to switch to the power consumption state in time. Li Guihao calculated that it was conservatively estimated that it could save 100 tons of diesel and save 500,000 yuan for diesel. The other is the tire pressure monitoring system. Some cranes use rail type, and some use tire type. Most of the ports where Li Guihao is located is a tire crane. Tire leakage can cause tire wear to speed up, and drivers or maintenance personnel need to be checked on the spot. After the tire pressure monitoring equipment is installed, the leaky tire will be marked on the computer terminal, which improves the efficiency of the management tire. Li Guihao calculated that the amount of tires had decreased by 40 to 50 compared with previous years. The market price of a tire was between 10,000 to 20,000 yuan. The cost of this item was about 700,000 yuan.

With many years of efforts and innovation, Li Guihao was named Ningbo Zhoushan Port Group "Harbor Artisan" in 2019. In 2019, he was awarded a model of labor in Zhejiang Province. Essence

How is the application -oriented innovative person made?

"We (application -oriented engineers) have to be made. I am talking about college graduates now. If you can only talk about your mouth, do not have the ability to do it, the old master also doesn't look at you. You can do it , To solve the problem, others are looking at it, and naturally you have some leadership. "Li Guihao emphasized that practice plays a vital role in his own growth.

Li Guihao University studied at Zhejiang University of Technology's integration of mechanical and electrical and electromechanical, and was "well matched" with the employment of electrical repair. When he didn't understand the principles of some equipment in his work, he would turn over the university's professional class books. "But there is no practical experience in the school." There are experimental lessons in the school, but Li Guihao did not take it seriously. Now he thinks that he thinks it is actually a good exercise opportunity. "Although he only learned some theoretical knowledge in the university." Li Guihao said, but compared with ordinary vocational school graduates, he is easier to contact the theory and solve the problem in the essence of the problem.

At the beginning of the employment, Li Guihao followed the teachers in the company to learn the basic situation of the equipment. Sometimes he couldn't understand the operating logic of the equipment structure. After get off work, he brought the equipment drawing back to the dormitory and continued to study. About a year later, he began to perform equipment maintenance. After another year, the company wanted to transform two dragon gate cranes in a scrapped state, and the leader asked Li Guihao to participate. As a young man who has not just been at work, Li Guihao feels that the opportunity is rare. Later, he thought it was the most important project in his career growth. "Because it is difficult to encounter such a thorough transformation project such as the device, this process makes me understand the bottom principle of the overall operation of the equipment. Because of these equipment in the 1990s, I met the oldest equipment. In fact It is very helpful for me to deal with new equipment later. "

Now that he is bringing new colleagues, Li Guihao finds that they are not much better than themselves, and their practical experience is still lacking. I was slowly exploring from scratch. There are not many opportunities like this today. "I have done it for more than a year on the front line. Time, the company's projects also have a lot of projects, and they need to enter the state of work quickly. " Therefore, in the work, Li Guihao always gives young colleagues as much as possible to experience the opportunity to experience on the spot.

In addition to practical ability, application -oriented innovative talents also need innovation capabilities. "Our company has always been advocating innovation. Our predecessors will take the initiative to solve the pain points of equipment operation." The company's Youth League Committee led the establishment of a youth technology group. Li Guihao joined in 2011 and was recognized and encouraged. He also participated in several dragon gate hanging innovation projects, such as automatic oil switching systems, automatic vehicle automatic correction system, and energy feedback system. Under the leadership of old employees and technical experts, Li Guihao gradually grew up. "Growing up in such an environment is very great. I dare to make some corrections to the equipment." Li Guihao said, "Because of the support of old experts and old technicians, we also have confidence and courage as newcomers to propose to propose to propose Some innovative ideas. "Although the company's early equipment was imported from Japan, Li Guihao had such an idea:" Not to say that their equipment is perfect. "

But to turn the idea of ​​innovation into reality, that is another thing. "All of our large projects have a very high trial and error cost." Li Guihao said, when doing dragon door hanging energy feedback system, its innovation is that when the piano fell with a container, the current feedback was fed back to the power grid. That is, when the box is lifted, the electricity is used to "power the power" when putting down the box, which can reduce the energy consumption of the single box by about 20%. However, Li Guihao and colleagues should consider it carefully that energy feedback will interfere with the power grid. One may have a small impact, but the company had more than 50 equipment at that time. In addition, the system cost of a set of energy feedback should also be hundreds of thousands of yuan. If the final result is not satisfactory, it is unimaginable for the consequences of one or two million yuan. "So the process of our promotion will slow down, more cautious." Li Guihao calculated that the entire transformation process lasted about 5 years. "So applied innovative talents, he can not do research, but he should have systematic thinking and integrate the areas where different technical services work." Data from the Ministry of Transport show that current international shipping has been responsible for about 95%of my country's foreign trade cargo transportation volume It has played a vital role in ensuring the smooth operation of the national economy. Li Guihao, who grew up on the front line of equipment maintenance, told reporters: "In the future, digitalization and intelligent construction need to learn more about wireless communication, laser radar, and Beidou positioning these high -tech applications. High requirements have also opened a new situation for our career development. Only by working can we keep up with the pace of development. "
