As shown in the picture, I've just started working in this field. I'd like to ask you about the paving machines for paving asphaltHow does the paver automatically level up when the asphalt is laid? Thank youAs shown in the graph, I have just engaged in this industry, I would like to ask you paver in paving asphalt is how to automatically leveling, what is the principle? For example, the paving layer should be paved 4cm, when paving, how to ensure that it is just 4cm? Sometimes the leveling device directly on the asphalt surface, to control the 4cm how to adjust? I don't understand what the wire line is how to determine the height, to find how high the shop is 4cm? Just pull it high? If not why directly on the asphalt surface on the line, put on the wire line? The height is different. Are they all 4cm? Compare the question of Doha, I hope to know in detail, do not copy paste, thank you for your help, thank you very much ~ ~!
The use of automatic leveling instrument is to ensure the longitudinal elevation, for example it is to ensure the wire paving surface from the wire has a fixed distance, so you wire a little higher, a little lower does not matter, as long as the wire frame after calculating Chutan pavement should be from the wire distance on it. When the longitudinal joint is used, the longitudinal shoe of the longitudinal wave instrument is directly placed on the paved pavement, which is the same principle. It guarantees the smoothness of the new paving and the paved pavement. The use of longitudinal instrument cannot use a screwdriver or steel to tie the thickness, this is actually wrong.
Just say the paving width unchanged, if the width changes the dynamic balance of mechanics is changing, so the scale position is wrong, if the width increased, shop or 4 cm scale certainly greater than 4 cm, in other words, if the ruler is 4 cm, pavement and thin, just speak with elevation, elevation adjustment mechanism, the replacement of paving thickness is big elevation, adjust the small called little elevation (Big Elevation direct conversion such as water stability and asphalt 27 cm 8 cm replacement, will adjust the mechanism. Small elevation, usually screw thread, there are individual machines did notIt seems that you are a careful pondering people above is a mechanical sensor, which is using a belt or gear transmission is an analog signal, with ultrasonic wave, when using them, it has 0, namely with wire or ground has an angle of 45 degrees, 45 degrees angle once it is destroyed, he will automatically modified to reach a new equilibrium, the angle is 45 degrees, if not 45 degrees, the instrument may not work. For reference only, for communication only.
As shown in the diagram, how does the paver automatically level up when paving asphalt? What is the principle? Very complex, can not be detailed, paver principle similar to the water windsurfing, that is, the initial generation of paver. The key points of paver spreading, big arm, ironing board, elevation mechanism, etc.. Simply speaking, the ratio of the width of the large arm to the screed is constant for a paver (fixed value). The product of this value and the adjustment is approximately equal to the change in the scale. Someone will ask me why not shop 4 cm to 4 cm scale, this is paving machine 0, if the paving width is constant, then adjust the small elevation can be done, but the paving is a dynamic balance, if the balance is broken, the scale may not be 4 cm, but after a while. It will return to the position of 4 cm.
