Description
Technical field
The present invention relates to road surface Work machine apparatus field, more particularly, it relates to a kind of, there is automatically looking for of cleaning function
Flat double-layer prestressed pressing plate.
Background technology
Pressing plate, as the core work device of asphalt-spreader, directly decides spreading quality and the serviceability of machine.
At present, domestic and international asphalt-spreader pressing plate all uses the rectangular box structure of Plate Welding, and bottom has been bolted
Wear-resisting bottom plate.When pave hot-mix asphalt mixture time, paver ironing plate base plate will be heated to the high-temperature of more than 130 DEG C,
And the plate casing upper part that plates is in ambient temperature conditions.Owing to pressing plate body structure upper and lower temperature difference is relatively big, it is in high temperature
The swell increment of lower part pressing plate much larger than being in the swell increment of upper part pressing plate of low temperature, thus cause whole pressing
Plate two ends occur upwarping phenomenon, thus cause the decline of paving concrete pavement flatness, have had a strong impact on the quality of construction of the highway.
Bituminous pavement paving machine is when starting working, if pressing plate is not heated, the asphalt material of high temperature will be bonded at
On cold wave flat board, when paving will scratch road surface, hair side phenomenon occurs.When, after end-of-job, scalding if cleaned not in time
Flat board, cools down hardening asphalt material and will cling parts such as vibrating, makes paver cisco unity malfunction, is therefore paving
Need after end the lower surface of pressing plate is carried out.
During operating paver, levelling sensor needs to raise whole flatness at an accurate degree line, so paves out
Road surface could be smooth, and evenness of road surface quality could be guaranteed.In the past, it is simply that at a support (every mono-support of 10m)
Pulling up a steel wire rope, steel wire rope needs to be fixed on support with iron wire colligation, and colligation point iron wire is higher than steel wire rope.Stand
During the work of paving machine, levelling of paver sensor roller sliding on a steel cord adjusts spreading evenness automatically.But due to two
Under the long iron wire that may result in the middle part of between two supports of distance between individual support occurs due to the reason of gravity
Situation about hanging down, the most then can cause the situation of the pavement roughness that paver paves to occur.
