Description
Technical field
The present invention relates to a kind of road surface construction machinery, especially adjustable integral type screed.
Background technology
Core work device of the screed as asphalt-spreader, directly decides the spreading quality and usability of machine
Energy.At present, domestic and international ironing plate of asphalt spreader all adopts the rectangular box structure that steel plate is welded, and bottom has been bolted
Wear-resisting bottom plate.When pave hot-mix asphalt mixture when, paver screed base plate will be heated to more than 130 DEG C of high-temperature,
And ambient temperature conditions are partially on screed casing.Due to screed body structure upper and lower temperature difference it is larger, in high temperature
Swell increment of the swell increment of lower part screed much larger than the upper part screed in low temperature, so as to cause whole screed two
End occurs upwarping phenomenon, thus causes the decline of paving concrete pavement flatness, has had a strong impact on the quality of construction of the highway.
In recent years, big width paver and modified asphalt mixture are applied in Expressway Construction, and
User is to the flatness requirement of road construction also more and more higher.For the increase and modified pitch mixing of paver paving width
The construction of the high temperature material spreaders such as material, can all cause the heat distortion amount at screed two ends to significantly increase.Existing screed heat becomes
Shape suppresses method, mainly thermal deformation is compensated by screed casing reserved heat distortion amount, and this needs to change screed
Physical dimension, and due to reserve heat distortion amount it is small-sized, its processing and installation difficulty it is very big.And it is most of at present
Ironing plate of asphalt spreader does not take effective thermal deformation suppressing method, and work progress screed is heated the amount of being deformed,
The operation quality of paving concrete pavement is had a strong impact on.Especially needed one kind can be with freely regulated integral type screed.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention to provide a kind of adjustable integral type screed, this is adjustable
Integral type screed adjusts the work area of screed with the increase of the first right extension and reduction by the first left extension, and
And first left extension and the first right extension the extension of increase is fixed by installing hole, be so easy for installation and removal.
The present invention solves the technical scheme that adopted of above-mentioned technical problem；
Adjustable integral type screed, including matrix screed, shown screed include principal piece, extension and base plate, described
Principal piece and extension are mutually assembled by base plate, and base plate is fixed by a pin to principal piece and extension, further solid by nut
It is fixed；The principal piece includes left principal piece and right principal piece, and extension includes the first left extension, the first right extension, the second left extension
Section and the second right extension, the upper end of left principal piece connection end are provided with projection, and lower end is provided with mounting blocks, the upper end of right principal piece connection end
Mounting groove is provided with, lower end is provided with mounting blocks, and the left principal piece coordinates assembling by the mounting groove on projection and right principal piece, further
Further fixed by bearing pin by the mounting blocks of left principal piece and right principal piece lower end, the second left extension extends by first
Left section is connected with the other end of left principal piece, and the second right extension passes through the other end phase of the first right extension and right principal piece
Connection.
One end of the first left extension and the first right extension is provided with installing hole, installing hole include the first installing hole and
Second installing hole, the first installing hole are arranged on one end of the first left extension and the first right extension, and the second installing hole is arranged on
First left extension and the other end of the first right extension, the diameter of the diameter of the first installing hole less than the second installing hole, and the
The periphery of one installing hole is provided with some little installing holes, and some little installing holes are arranged around the first installing hole.
The size of increase and reduction regulating base board of the base plate according to extension.
Beneficial effects of the present invention：Adjustable integral type screed is by the first left extension and the first right extension
Increase and reduce to adjust the work area of screed, and the first left extension and the first right extension are consolidated by installing hole
Fixed increased extension, is so easy for installation and removal.
