Ice and snow, the highway was trapped for more than 30 hours, the father and son are pondering to create a "shasha car"
Song Chunji is a big cargo driver with 26 years of driving experience. He is from Xizheyang Village, Fangyuan Sub-district Office of Haiyang City. He and his son both graduated from junior high school. After graduating from his son, he also ran with his transportation.
In the days when the father and son were running and transporting, they had a special sensitivity to the weather and the road. Every time they traveled, they always looked at the weather and had a good weather. However, the "face" of God is not transferred by the will of the people. Every winter, especially in the north, ice and snow are everywhere.
I can't remember the year of winter. The father and son drove a large truck on the expressway from Shijiazhuang to Taiyuan. They went to a slope, and the world was snowing. The big and small vehicles could not go up, or they would stop at the mountainside. Or it is impossible to get down the slope, and the snowy road becomes a parking lot. The large trucks they drove were more horsepower, and they "luckily" drove to the top of the slope. When they went downhill, they saw the road as bright as a mirror, and the father and son did not dare to go down. Helpless, like other vehicles, I was looking forward to the rescue in the biting cold wind.
Finally, the local highway management department came to the rescue, calling a lot of trucks and tractors, dragging industrial salt and manually throwing it on the road.
"At that time, looking down from the top of the slope, the entire road was full of people and various vehicles. However, artificial sanding was slow, uneven, and the anti-slip effect was very bad." Since the past, Song Chunji still remembers it.
"People who haven’t stayed in that cold weather can’t appreciate the taste.†At that time, looking at the salt-spraying scene, Lao Song couldn’t help but ask the driver of the salt-salted car: “Salt on the highway There is no mechanical method for the grain?†The driver said: “The anti-slip sand on the various roads in the country is all manual work. You can think of a way!â€
That time, they were trapped on the Shitai Expressway for more than 30 hours!
The driver said a joke, reminding the old Song. The father and son who had suffered a lot of trouble returned to Haiyang. The first thing they did was to ask the Haiyang Municipal Highway Bureau with the same question. The answer is the same.
In the torment of the snow that has been trapped again and again, Song Chunji wonders whether he can study a machine that replaces the artificially thrown sand-sand sand, solves the need for road throwing, and at the same time, allows more passing vehicles to be trapped by wind and snow. .
I sold my own large truck and studied it. It took more than a year to test nearly a hundred times. The mechanical throwing car came out. Lao Song named the car as a powder dumping car.
In January 2004, the father and son finally made up their minds to sell the big trucks they loved, and raised funds to start research and development of mechanical dispersal.
"Although my level of culture is not high, I have a special interest in mechanical things since I was a child, and I am willing to 'touch'. During my time as a soldier, I have won awards for ordnance repairs by my own research on machinery. After retirement I worked in the supply and marketing system. At that time, in order to solve the problem of artificial high installation, I designed the tower crane to solve the problem that the manpower could not solve. Later, I opened the big truck myself, and after a few years, I know the big truck 'five internal organs'..."
Talking about the fate of himself and the machine, Song Chunji has a lot to say. It is precisely because of the previous understanding of machinery, Song Chunji feels that the development of the throwing car should not be a problem.
I want to think about it, but it’s not that easy to do it. In his own words: "At that time, I thought about it during the day, I thought at night, sometimes I became fascinated, forgot to eat and sleep." Gradually, with the idea, "for the width and length of the road, throwing the car The load-bearing capacity should be different. For example, the country road and the county-level road can be equipped with a small-loaded dumping car, while the wide road and the long road such as the expressway require a heavy-duty throwing car. The internal structure and principle of the car are the same."
"Also, if the snow is too big, the snow is too thick, and some of it is more than 1 meter. Before the sanding, it is necessary to clean the road. Therefore, the designed car can not be used only for sanding, in order to save time and effort. It is best to do shoveling snow and sanding in one go." Thinking of this, Song Chunji's idea opened, he added the usual snow shog function to the car, and then focused on the development of mechanical sanding function.
At this point, the old Song mind has a large-scale concept of the car, but only the idea is not enough, but also through the use of drawing design to complete, and the father and son who graduated from junior high school do not understand the drawing design. To this end, he specially sent his son to study specifically. Two months later, his son returned to study. For Song Chunji, he was even more powerful. Since then, the father and son have been "indulgent" in the development of the car.
They first designed the size of the parts, then sent them to the processing plant for processing, and then instructed the mechanics to install them a little. In order to accurately calculate the design, it is common to sleep for only one or two hours a night. Many times, sleep until midnight and climb up to draw the design. After many sleepless nights, they can't even remember themselves.
Perhaps they were in the mood of a big cargo driver. They used the Steyr three-car to make a chassis with a 266-horsepower diesel engine, which can hold more than 30 tons of throwing material at a time.
In order to prevent the throwing car from being blocked on the snow road, Song Chunji also provided the car with a self-use anti-skid device. This device can throw two anti-slip belts in front of the rear wheel of the car to ensure that it will drive safely on ice and snow and steep slopes.
Hard work pays off, the father and son finally developed a mechanical throwing car. They were happy to drive the molding car to the road and found that because the design has only one discharge speed and the width of the road, it means that the sand surface needs differently. The two continued to study and set the discharge speed to four, so that the speed of materials used and the amount of materials used in different roads were selected. The wide pavement can choose a higher discharge speed, and the amount of sediment is relatively large. When the pavement is narrow, the lower discharge speed can be selected, and the amount of sand discharged is small, so as to achieve flexibility.
After about a year and nearly a hundred research experiments, they finally succeeded in developing a mechanical throwing car and produced a prototype car! They called their own car a "powder throwing car."
At the end of last year, their research results were granted patents by the State Intellectual Property Office.
The news that the big cargo driver invented the multi-purpose road "powder throwing car" has gone away. Many people think that in the future, there is no need to use the "human sea tactics" to throw sand on the road.
In the winter of 2005, the heavy snow in the past 100 years, the people of Hong Kong are still fresh in memory.
After a blizzard of more than half a month, the entire city was covered with snow. Heavy snow covered the road and covered the airport. People's travel and road transport became difficult. Starting from safety, from December 3 to 15 last year, the highways in Tongtai, Weiwu, and the city were disconnected according to the snow conditions, and the closing time was more than 160 hours. The spectacular scenery of thousands of people sweeping the snow The scene appeared again and again in the city.
The blizzard's "Yuwei" has passed, and Song Chunji's father and son's determination to develop a car to cope with the snow and snow has never stopped. In order to make this patented technology more stable, they are still constantly experimenting and improving.
After the Spring Festival today, Haiyang City had two days of heavy snow. The local highway department heard that he developed such a multi-purpose spreader car. He hoped that the car would "reach his hand" and Song Chunji would like to show himself in front of everyone. The result, however, unexpectedly, when the car drove to the sand to install sand, it was intended to discharge the unspent sand from the previous day, but it could not be discharged. Moreover, it also damaged the bearings inside the car and Axis, he rushed to find the reason. It turned out that the day before, the road was snowed and sanded. After the car was opened, it was placed in the open air. The sand on the car was not used up. The snow melted into the feeding device that night, water and sand mixed. , formed a large ice cube. To this end, Song Chunji has re-improved and added a clutch device. As long as the above situation occurs, the clutch device will function, and the machine will automatically stop the transmission to ensure that the machine is intact.
In this way, the test is repeated once and for all, and the performance of this throwing car is increasingly stable, safe and reliable.
The news that the big cargo driver invented the multi-purpose highway "powder throwing car" went away, and the local authorities were amazed after seeing it. Some leaders and experts believed that the product of this product greatly improved various roads, especially high speed. The degree of mechanization of road maintenance and emergency dispersal. With this kind of mechanical work, the manpower, material resources and financial resources saved are incalculable, and there is no need to use the “human sea tactics†to throw sand on the road.
Existing manufacturers are very optimistic about the market of this product, and Song Chunji to discuss cooperation intentions, several highway departments are also very concerned, and repeatedly went to the field to check.
"This product has an efficient use value." Talking about the market, Song Chunji is very confident. He said: "In winter, in order to prevent roads from snow and ice, many places piled up a lot of sand on both sides of the road. When snow and ice were frozen, artificially spread sand and salt particles onto the road; especially on the highways in the north. Winter snow and ice will close the road, all vehicles can not drive, and the emergency method is to use the truck to drag sand or salt particles and manually throw it to the road. This kind of mechanical operation is easy to operate, and the driver is driving. After training, the staff can operate quickly. 'One person, one car' can replace the 'multi-person and multi-car' operation, which can save a lot of manpower and financial resources, the anti-skid effect is good, and the social and economic benefits are particularly remarkable." Forecasting the future market Prospects, Song Chunji is more optimistic.
With the growing maturity of the throwing car, Song Chunji and his son are also throwing the seeds of their hope.
