Description
Technical field
The utility model belongs to maintenance of surface implement technical field, is specifically related to a kind of finish-milling for pavement milling machine plane rotor.
Background technology
Pavement milling machine is one of main machine of maintenance of surface operation, maintenance work is carried out for diseases such as the rut to flexible pavement, carbuncle bag, be full of cracks, milling is carried out to damaging road surface by the milling rotor be arranged in milling planning rotor cap case, and the old material of milling is cleared up and reclaimed, to lay new road surface.
Milling rotor is one of vitals of pavement milling machine, and the epitrochanterian cutter of milling is then direct milling road surface functional component.The epitrochanterian cutter of milling is primarily of tool rest, and the broach shell (being also tool magazine or tooth cover) that tool rest is arranged and the cutter head (being also pick) be nested in broach shell are formed.
Conventional milling rotor cutter spacing is 15 millimeters, and the texture spacing that milling goes out is relatively large, and the surface evenness after milling is relatively not high, only to meet the conventional maintenance work of road pavement.Finish-milling plane rotor is relative to common milling rotor, and the milling rotor cylindrical shell of equal length equips more cutter, and cutter spacing is much smaller than 15 millimeters.Finish-milling plane not only can carry out certain thickness milling process to aging road surface, realizes levelling, milling can also go out new, a finegrained road surface of tool, thus increase the frictional force on road surface on the flexible pavement of ageing paving, cement pavement.Be specially adapted to tunnel, bridge floor plucking, flexible pavement micro-surface area and new pavement interlayer management maintenance aspect.Because the finish-milling plane milling degree of depth can not affect original surface layer, the road surface therefore after finish-milling plane need not overlay new surface layer just can open to traffic rapidly.In addition, if the object of finish-milling plane removes the out-of-flatness on tack coat, then the wearing layer of high-flatness can be overlayed thereon.
Although finish-milling plane is a kind of desirable cost-saving, prolonging service life of pavement and maintaining process fast, but the manufacture of finish-milling plane rotor is to the arrangement of the outer cutter of cylindrical shell and welding process requirement harshness, therefore, successfully producing the finish-milling plane rotor meeting construction operation is the key realizing road surface finish-milling plane maintenance work.
Utility model content
The purpose of this utility model there are provided a kind of finish-milling for pavement milling machine plane rotor, to meet the needs of road surface finish-milling plane maintenance work.Rationally, set of knives component firm welding on cylinder body outer wall, is convenient to old material and dishes out, and is beneficial to the application life extending set of knives component in multiple set of knives component arrangements of this finish-milling plane rotor.
To achieve these goals, the utility model takes following technical scheme:
A kind of plane of the finish-milling for pavement milling machine rotor, comprise cylindrical shell, the two ends of cylinder inboard wall are provided with rotor reductor mounting flange, the outer wall of cylindrical shell is welded with multiple set of knives component, multiple set of knives component is to two groups of helix arrangements at its two ends in the middle of cylinder body outer wall, and the projection of set of knives component overlaps with the helix at its place, and two groups of hand of helixs are contrary, often organize helix and comprise six, the level interval of adjacent two helix centers is 5 ~ 8 millimeters.
Further, the set of knives component of the described plane of the finish-milling for pavement milling machine rotor is made up of tool rest, broach shell and cutter head, the bottom welding of tool rest is on cylinder body outer wall, the top of tool rest has the installation through hole of socket broach shell, the broach shell being sheathed with hollow in through hole is installed, the inside socket cutter head of broach shell; Install axis and the broach shell of through hole, the axes coincide of cutter head, installation through hole overlaps with the helix at its place with the projection of the axis of broach shell, cutter head.
Preferred as technical scheme, the external surface of described broach shell has the tapering of 1:10, and the inner surface installing through hole has the tapering matched with the external surface of broach shell.
The beneficial effects of the utility model are mainly reflected in:
(1) multiple set of knives components of finish-milling plane rotor described in the utility model are two groups of contrary helix arrangements, often organize helix and comprise six helixes, the level interval of adjacent two helix centers is 5 ~ 8 millimeters, and the distance between set of knives component is less than conventional milling rotor cutter spacing.Through the maintenance milling and plane operation of flexible pavement repeatedly, cement pavement too much, this finish-milling plane rotor not only can realize levelling to aging road surface, milling can also go out fine texture, spacing and the cutter spacing of adjacent fine texture center line match, and well meet the technical requirements of smart milling and plane operation.
(2) set of knives component described in the utility model design and installation are more reasonable, tool rest installs the axes coincide of the axis of through hole and broach shell, cutter head, especially, the external surface of broach shell has the tapering of 1:10, and the inner surface installing through hole has the tapering matched with the external surface of broach shell.Such design, can reduce the spoilage of cutter, extend cutting-tool's used life, reduces construction operation cost.Meanwhile, the dismounting being also convenient to broach shell and cutter head is changed.
(3) the set of knives component arrangement of finish-milling plane rotor described in the utility model rationally, be easy to dish out the old material in road surface of milling, avoid the filling of old material between cutter to pile up, alleviate the workload of the regular maintenance of finish-milling plane rotor, meanwhile, the whole service life of finish-milling plane rotor is also extended.
