Door machine hero Kong Xiangrui, he has a unique skill

Kong Xiangrui, "the most beautiful strivers", studies hard and studies diligently on weekdays.

Once, the rotating bearings of a gantry crane on the dock had an abnormal noise. In general, this abnormal noise may be caused by a lack of lubrication, but it can also be a precursor to a major accident. Therefore, a dilemma is in front of us: if it is not disassembled for a thorough overhaul, the door machine may be paralyzed; if it is dismantled and found that there is no problem, the company will suffer millions of yuan in economic losses.

To dismantle or not to dismantle? The leaders and workers present had no idea, but looked at Kong Xiangrui with expectant eyes. Kong Xiangrui only made one action at that time, and decisively made the judgment that the bearing was broken, saying that it must be dismantled. But after dismantling, the result was unexpected.

What exactly did Kong Xiangrui do? Why was he so decisive in making the decision to demolish? And what is the final result?

To answer this question, let's start with Kong Xiangrui's growth process.

First, go to class for three days and go back to work

In 1985, Kong Xiangrui was already an old worker who had opened a gantry crane for more than ten years. As the duty captain and technical backbone, he was given an opportunity to attend the pre-examination training course of the staff university. However, in the classroom, others cannot let go of their work. School takes up time, and he is inseparable from the post. So, on the third day of class, he made a decision: to return to work and say goodbye to class.

That's how he loved his job. He has a strong sense of responsibility and ownership, and has always devoted himself to his work for 35 years.

At 3 p.m. on July 1, 1999, the ground temperature at the Tianjin Port Terminal operation site had reached 40 degrees Celsius. In such a high temperature, a working main door machine suddenly short-circuited and caught fire. The surface of the door machine has been scorched by the sun, and the temperature of the smoke-filled tin machine room has exceeded 50 degrees Celsius. Kong Xiangrui was impatient. At that time, due to the emergency of thermal coal in the power plants of the five southern provinces, the State Council urgently ordered the transportation of thermal coal. "Military emergency!" In that high temperature, Kong Xiangrui took the lead and was the first to enter the machine room. At that time, the machine room was like an oven. His eyes, corners of his mouth, and overalls were soon covered in sweat. He and his 5 co-workers sweated profusely, their throats smoked, and they drank 5 boxes of mineral water, but no one went to the toilet. Kong Xiangrui let the workers take turns out of the machine room to catch their breath, but he has been stuck in the machine room and kept rushing to repair. It wasn't until 11 p.m. that the fault was finally repaired and the loading operation could continue. Kong Xiangrui had been working in that environment for a full 8 hours. Kong Xiangrui's body was already as soft as cotton when he stepped out of the big jar, and he sat paralyzed on the ground, gasping for breath for a long time.

Second, diligent in learning, good at thinking

In 1972, at the age of 17, Kong Xiangrui was assigned to the Tianjin wharf. Tianjin Port is the second largest coal launch port in China, and Kong Xiangrui's job is to work as a door crane driver in such a port. Over the years, Tianjin Port has always attached importance to technological innovation, adhering to the competitive distribution principle of "who contributes to the profit, who innovates and who wins the award", and gives heavy awards to inventors of practical technological achievements and advanced processes, and hosts of major projects. Kong Xiangrui always insists on learning, and he often learns while doing. He always carries a notebook full of problems he finds and ideas for solving them. In order to grasp the new equipment and new operating technology imported from abroad as soon as possible, he always packed the data in the bag, took it out and carried it when he had time, and then went to the equipment to compare and understand.

Kong Xiangrui believes that as long as they study hard and study hard, workers can also display their talents. His knowledge of the equipment of various positions and his familiarity with various operating techniques have made him a famous "door machine king" and "obstacle removal expert".

In 1995, he was serving as the secretary of the party branch and the captain of the solid aircraft team in Tianjin Sixth Company. His job is to take charge of the company's core equipment for loading and unloading production – 18 40-ton door machines. Once, the No. 12 door machine failed and could not continue the production task. Before repairing the door machine, the 168-ton door machine needs to be lifted. In the past, to solve this problem, it was necessary to rent a sea crane operation, and it was necessary to wait for two months. Kong Xiangrui does not want production to be affected, but also likes to study, he relies on his long-term accumulation of practical work experience, decided to find a way to solve the problem. He led the workers to repeatedly observe and study repeatedly, and finally overcame the difficulty that the lower fulcrum was not easy to fix due to bearing rotation. In the end, they chose to use 10 individual jacks with a pressure of 30 tons to lift the 168-ton door machine to the plate, so that the door failure could be repaired. Since then, a new achievement has been produced, that is, a new apical bearing technology welded under a large flange.

Third, technological innovation, blue-collar experts

Kong Xiangrui has presided over more than 150 technological innovation projects and obtained a number of national patents. He has created a value of 96 million yuan for the enterprise, and is a "knowledge-based industrial worker" that everyone admires. He believed that practice produced true knowledge, and repeatedly gave up the opportunity for further study and stayed in the workplace. The workplace is his classroom, the production practice is his teaching material, equipment failure is his subject, and the lovely co-workers who are skilled are his teachers. He worked hard and constantly overcome one technical problem after another, and finally won the reputation of "blue-collar expert".

The rotating bearings of the gantry crane on the dock made a strange noise, and the business leaders and workers present all looked at him expectantly. Because he is already an expert in the hearts of the leaders, the most reliable partner in the hearts of the workers. In his long-term work and study, he has practiced the unique skill of "hearing the sound interruption disease", as long as he listens to the sound, he can know what is wrong. So this time, Kong Xiangrui calmly listened to the sound, and judged that it must be the bearing that was broken, which made the decision to dismantle. However, when the company invited 900 tons of offshore floating crane to carry out the operation, the door machine was slowly lifted up in half, and the slewing large bearing was removed, but the front of the slewing large bearing was intact and there was no abnormality. Did I hear me wrong? After thinking carefully, Kong Xiangrui thought that his judgment would not be wrong. He decided that the bearing must have been damaged, and that the intact bearing was only an appearance. Therefore, he calmly directed the crane to turn the large bearing over, and the answer was finally revealed. It turned out that on the back of the large slewing bearings that were intact on the front, the balls had already been scattered out of the groove. Bearings like this, if used continuously, have unimaginable consequences.

Fourth, overcome difficulties and work diligently to open up

In 2001, Tianjin Port hit the throughput of 100 million tons. As the largest loading and unloading company in Tianjin Port at that time, Kong Xiangrui's six companies undertook 25 million tons of work, which required 18 door machines to do one-third more work than usual.

This is not something that can be done with some maintenance and maintenance. You have to work hard to come up with brilliant ideas. During that time, Kong Xiangrui has been thinking about how to improve efficiency. His mind was full of door machines, repeatedly chewing every movement of the door machine grab operation.

Emperor Tian did not live up to his painstaking heart, kong Xiangrui finally found a breakthrough after repeated observation and thinking. He found that when the door grabber was released, the grapple should first be lowered into the cabin, then opened and then raised. And the moment you open the grapple to release the material, the machine will have a small period of stagnation. Don't look at this small period of time, if you save a small period of time with each action, the work efficiency will be greatly improved.

Therefore, Kong Xiangrui studied with the technical backbone of the team, trying to find a way to combine the two movements of grappling open material and light hook lifting. In the wisdom of the group, they came up with a brilliant idea. They enriched the trajectory of the joystick movement from a "ten" shape to a "☆" shape, and controlled two actions at the same time with one command.

As a result of this invention, the operating time of the door machine per hook was reduced by 15. 8 seconds, an average of 480 tons of work per day. One door machine can dry 480 tons a day, and 18 door machines can dry 8640 tons a day. As a result of this invention, the task of 25 million tons of the six companies in that year was exceeded, adding 16 million yuan to the company's efficiency. In 2002, this "door machine main orderer star operation method" was named "Kong Xiangrui operation method" by the Tianjin Federation of Trade Unions, and became one of the top ten excellent operation methods for employees in Tianjin. Later, this "golden idea" was promoted nationwide as a new technology that attracted the attention of peers.

Kong Xiangrui often said: "Dry, just do it!" ”

The slogan he most appreciates is: "Labor creates a better future." ”
