The forging workshop originally had a free-fall forging hammer built using a local method, but the efficiency was not high. It was barely used. As the level of industry continued to improve, the crazy people in the machinery factory planned to abandon this local equipment and build a 100-ton hydraulic press.
Later, I realized that this goal was too big, so I decided to start with a more primitive method: making steam forging hammers-the technical level of this thing is not high, but the effect is sufficient. There are two machines in Jiangnan Shipyard that were manufactured around 1880.
The steam forging hammer was still in service in the 1990s. The base was broken and the Jiangnan factory was reluctant to dismantle it, so it continued to use it after repairs.
With the steam forging hammer, the forging of many large workpieces has become much easier. The slide rail of the entire steam forging hammer is 5 meters high, made entirely of steel, and stands on a base of granite and reinforced concrete. The forging above
The hammer weighs 1 ton and is driven by steam pushing a sliding valve.
Compared with the free-fall forging hammer designed and manufactured by the previous machinery factory, the forging capacity and working efficiency of this forging hammer have been improved by less than three or four times. Originally, using a forging hammer was very laborious and required constant operation.
The steam engine lifts the forging hammer, and then uses a cam clutch to control the lowering. Each forging takes a long time, making it impossible to achieve continuous forging, which also brings great trouble to the heat treatment.
The forging shop quickly completed the processing of the mild steel jaw plate, and then used the same method to manufacture the toggle plate and eccentric shaft. After the eccentric shaft was completed, it was taken to the lathe for turning and shaping to make it as round as possible.
Finally, two large flywheels with a diameter of 1.2 meters were manufactured to connect the power machine.
These giant parts were loaded onto oxcarts and slowly towed to Nanbao. Because the ordinary four-wheeled oxcarts had limited carrying capacity, they were placed on a specially manufactured large flatbed truck with sixteen wheels.
Pulled by twelve oxen. No matter what the use of this thing is, this convoy alone is enough to arouse onlookers and discussions - the people along the road are extremely surprised by the Australians' waste of steel.
The equipment was installed in Workshop No. 1 of the newly built mining plant in Nanbao Mine. Workshop No. 1 is a large-span iron truss workshop built by Bingfeng, which is as high as three floors. The structure is supported by reinforced concrete columns. The floor is
Concrete was poured and iron rails were installed to push the ore.
A crane is installed on the ceiling of the workshop to transport a large dump bucket to load the crusher - according to Zhan Wuya's opinion, it is actually best to use a belt conveyor, but for the time being they do not have a suitable substitute.
Made of deerskin, it would be too luxurious.
Finally, Xiao Guilai installed the steam engine. Finally, the system was finally installed. A huge team consisting of steel and a huge base with a total weight of almost ten tons stood in the center of the workshop, not to mention the indigenous employees, even the travelers themselves
They all felt astonished.
As Xiao Gui ignited the boiler, the steam engine slowly started to rotate. Driven by the large gearbox, the last stage transmitted the power to the flywheel of the crusher through the belt. As the speed of the flywheel gradually increased, the crusher began to officially
Already working.
The workers used a flat rail car to transport a load of large rocks through the track. The crane on the roof used a steam engine to drive the pulley, and quickly lifted a huge stone and put it into the crusher. Boom, boom, boom, boom, the crusher is not tight.
Running slowly, the movable jaw slowly opens and closes. As the jaw opens and closes, the huge stone sinks deeper and deeper, and the clamp becomes tighter. The stone begins to break, and many debris fly out.
, with the sound of collapse, a puff of white smoke appeared, and the stone broke into several pieces.
Everyone present was shocked, but the people in the machine shop knew that this thing was running normally.
The jaw plate is still squeezing slowly and continuously, and the broken stones that become smaller are clamped tighter and tighter during the downward process, continuing to bear the squeeze of the movable jaw plate and the fixed jaw plate, and continue to
Broken.
Some gravel and powder began to appear at the discharge port. 100% dust began to spread. Then a large amount of gravel fell on the bucket truck at the discharge port.
There is a track below the discharge port, and a group of bucket trucks are parked end-to-end under the discharge port. They are intercepted by cables on a winch driven by a steam engine. After a truck is full, the operator starts the machine to pull the truck.
Two trucks can be changed under the discharge port until one row of bucket trucks is fully filled, and then the second row can be changed.
The loaded bucket truck group is pulled to the loading station on the slope, and is dumped directly into the bucket of the bullock cart by taking advantage of the height difference before being transported away. The entire process requires minimal manual loading and unloading.
Zhan Wuya calculated that if only the gravel used for construction is crushed, the crusher can process almost fifty tons of gravel every day. If these crushing tasks are done manually, three to four hundred people can't do it.
But now, including boiler maintenance workers and overhead crane operators, a shift of twenty workers is enough. The difference in labor efficiency can be described as earth-shaking.
But to the local people, this rumbling stone crusher represents terrifying power. If such a hard boulder can be crushed into pieces, what else can't this group of Australians do?
But the surprise was not over yet. After the crusher proved usable on the first day, in the following six months, three more crushers were installed at Nanbao Concentrator. This had a devastating effect on the local people.
As a result, no matter what work the Crossing Group carries out in the local area, it goes very smoothly. The local gentry and people simply obey what they say. In addition, many people who were not very interested in working in the mines as workers have come to do odd jobs. Even the landlords and gentry families have sent a few
A domestic slave or a nephew came to work - in order to establish a relationship with the Mining Department.
With enough gravel, the transportation department made rapid progress in hardening the road surface. Shan Daoqian used gravel as the roadbed to increase the bearing capacity of the roadbed, and then used cinders and fine gravel on the surface to smooth the road surface. After a few more
After the first rolling, the road became as smooth as new - even higher than the low-grade roads in rural areas in some places.
In addition to the road rollers used in construction machinery, Shan Daoqian also cooperated with machinery factories and vehicle factories to develop animal-drawn rollers - this is simple, just a huge stone roller with an animal-drawn traction belt. It is slightly more complicated.
They are animal-powered rakes, sprinklers and pavers. These can currently be pulled by horses, oxen or manpower. These special equipment not only reduce the wear and tear on construction machinery, but because they are self-produced equipment, they are less expensive.
It is so rare that the Transportation Bureau ordered several sets at once and started using them on many road sections at the same time.
Shan Daoqian applied for dozens of worker quotas from Wu De, established a road maintenance engineering office, built road maintenance stations along the way, and formulated regular inspections, maintenance and maintenance work rules for the highway.
"There is another thing to do, which is to fix traffic regulations." Shan Daoqian found Wu De.
Originally, Lingao did not require traffic regulations. In addition to pedestrians, there were at most a few sedans and wheelbarrows. Occasionally, a few horses passed by. No matter how narrow or uneven the dirt road was, there would be no traffic accidents. However,
It’s different now. The arrival of crossing groups has greatly increased the complexity of traffic conditions on the road. In addition to the increasing number of pedestrians, there are also ox carts, livestock, bicycles, cars and motorcycles. The construction of roads has also brought new problems.
For example, intersections, bridges, etc. all require a certain degree of control - there have been several traffic accidents recently.
"Let the police take care of this matter." Wu De said, "Dongmen Chuiyu is in charge of this matter."
Dongmen Chuiyu has been responsible for the management of Dongmen City for a long time and has some experience in such matters. He said: "I think there is no need to make too complicated traffic laws and regulations for the time being. First of all, ordinary people can't remember them. We publicize them
It’s also difficult to get up; secondly, we don’t have so many manpower to conduct on-site inspections and the like.”
When Liu Bang came to Guanzhong, he only made three chapters. Although it was a huge step backward from a legal perspective, it was easy for the masses to understand and grasp, and it was easily accepted in the initial stage.
The basic principle of Dongmen Chuiyu is: "Keep to the right when walking, overtake on the left, and separate lanes for speed and slowness."
According to the rules, pedestrians, sedan chairs, livestock, take the slow lane, and horse-drawn carriages, ox-carts and motor vehicles take the fast lane. Logically speaking, the speeds of motor vehicles and ox-carts are very different, but motor vehicles have rarely been on the road recently, so they will not
causing traffic chaos.
Herding livestock, such as cattle and sheep, are not allowed on the road and are only allowed to walk under the roadbed. Large groups of livestock on the road can easily cause road blockage.
Shan Daoqian said: "However, it is best not to honk the horn of motor vehicles, so as not to disturb the livestock. And it is simply wishful thinking for you to expect the heavily loaded ox carts on the road to let you pass. It is better to pass by yourself."
"There must be some punitive measures. Pedestrians walk on the side. What if he likes to walk in the middle?" Dugu asked.
"Relying on fines is not enough." Dongmen Chuiyu dragged his chin, "First, implement the concept of "killing someone in a collision, a collision in vain". Those who violate traffic rules and cause casualties and property losses will not be compensated - "
"Hold on, this is not the main point," Shan Daoqian stopped him, "I agree with what you said, but now we have to talk about ordinary minor violations first. With our current power, even if we really kill a few people,
No one dared to ask for an explanation."
"Catch the labor reform team!" Dugu proposed this method.
"This can also increase the labor force." Dongmen Chuiyu agrees. Anyway, minor violations are now compensated with labor force, ranging from three days to three months.
Shan Daoqian said: "I think it's good. Anyone caught violating traffic rules will be assigned to our transportation bureau."
The Transportation Bureau has many projects and affairs, so the more free labor the better. It not only builds bridges and paves roads, but also directs traffic.
