There are many types of road machinery and equipment. Generally speaking, construction machinery is the common shovel equipment such as excavators and loaders or the equipment such as cranes. Now let's get to know some Jinan road machinery and equipment.
The paver is a little familiar with most other pavement equipment, but non professionals must not have had a thorough understanding of it. Some people may still think that the paver is only used to pave asphalt pavement, but in fact, it is not. Many of the water stabilized layers are paved by pavers now. Of course, the water stabilized layer is also paved by excavators or graders, but the compactness and flatness of the paver are better, The paver shall be used to spread water stably for those with high construction requirements.
The paver is operated by three people, and several surfaces above are responsible for the operation. The operation is controlled according to the amount of material in the dump truck and hopper. The dump truck folds the hopper after moving. Of course, other upper surfaces can also be controlled. However, due to the poor distance from the far view, two people are also responsible for the operation at the rear ends.
2、 Cold regeneration
Cold recycling refers to the process of continuously milling and crushing the old pavement structure layer, including the surface layer and some base layers, adding recycled materials, mixing, paving, rolling and other operations using special cold recycling machinery at room temperature, to re form a structural layer with a certain bearing capacity.
Cold regenerator is a kind of construction machinery with high efficiency and multipurpose. It is mainly used for milling of asphalt concrete pavement and recycling of old asphalt pavement after adding asphalt, water and other materials. It can also be used for on-site mixing of base and bottom stabilized soil of highway, urban and rural roads, airport, wharf, parking lot and other projects.
3、 Milling machine
Today, with the rapid development of construction machinery, the scene of excavator used for road construction has disappeared and is replaced by milling machine.
There are two tracks at the front and two at the back. The four small tracks look very solid. Each track is supported by a column. This is the legendary four-wheel independent suspension! The traveling motor has no guard board and is exposed, which may be due to the fact that the asphalt road is often used instead of going up the mountain. The hydraulic cylinder on the milling box looks very slim, but it should be enough. After all, it is matched and designed by engineers.
The hydraulic cylinder pushes the column on the track to drive the track to turn. In order to make the tracks on both sides turn synchronously, the connecting rod is used to connect the two sides. How the two steering wheels are controlled is not clear. The two front tracks are connected by connecting rods, and the two rear tracks are also connected by connecting rods. The two steering wheels should have the same function, just to facilitate operation at different angles.
The steering mechanism of the rear track is the same as that of the front track, but there is not so much behind it. It looks clearer.
Pavement engineering occupies a large proportion in engineering construction, and pavement machinery and equipment also play a very important role in the whole engineering machinery. If you have any needs, you can contact us at any time http://www.ycgjglcl.com ！
