Two class of tire formula.
The prior art can refer to the Chinese invention patent application file of application publication number CN107893358A, open one kind
Road roller with vibrator, including road roller ontology, driver's cabin, wheel and pressure roller, road roller ontology front end are equipped with institute
Driver's cabin is stated, cab bottom ground proximity position is equipped with flattening mechanism, and the driver's cabin is arranged right below the wheel,
Bottom position is equipped with water jet in the middle part of the road roller ontology, and road roller body tail section position is equipped with the pressure roller, described
Pressure roller interior surface is equipped with vibrator, and the pressure roller two sides are equipped with elevating lever, and the elevating lever bottom is connected and fixed wheel, institute
It states and is equipped with hydraulic cylinder inside elevating lever.
Pressure roller use for a long time may be damaged, since pressure roller is heavier, so as to cause being not easy to replace pressure roller.
Summary of the invention
The object of the present invention is to provide a kind of municipal works road roller, including rack, pressure is removably connected in rack
Roller, convenient for being replaced to pressure roller.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of municipal works road roller, including rack are provided with driver's cabin at the top of rack, and rack is located at the side of driver's cabin
It is provided with pressure roller, the pressure roller is removably connected in rack；The front end of the rack is installed with fixed frame, and pressure roller detachably connects
It is connected in fixed frame, the two sides of fixed frame one end offer inserting groove, and fixed link is plugged in inserting groove, and fixed link is plugged in slotting
Fixed link and fixed frame are fixed by bolt after access slot；Pressure roller includes being rotationally connected with fixed link middle part fixed frame far from fixed
Roll shaft in the middle part of bar one end, the axial direction of roll shaft is horizontally disposed, be arranged with outside roll shaft three successively grafting roller one, roller two with
And roller three.
By using above scheme, when needing to disassemble and install pressure roller, fixed link is taken from one end of fixed frame
Under, successively roller one, roller two and roller three can be removed from roll shaft from fixed frame close to one end of fixed link, simultaneously
Replace roller one, roller two and roller three, or the progress that will have damaged roller one, roller two and roller three that is looked for damage
Material is not only saved in replacement, but also the weight of roller one, roller two and roller three only has original compared to original pressure roller weight
The one third come, lighter in weight, moreover it is possible to be conveniently replaceable.
The present invention is further arranged to: connection type between the roller two and roller three and roller one and roller two it
Between connection type it is identical, roller one is uniformly provided with groove along its circumferential direction close to one end of roller two, and roller two is close to roller
One one end is circumferentially uniformly installed with convex block along it, and convex block can be plugged in the groove of roller one, be threaded on convex block
Hexagon socket head cap screw.
By using above scheme, when installing to roller one, roller two and roller three, insert the convex block of roller two
It is connected in the groove of roller one, then by hexagon socket head cap screw that roller two and roller one is fixed, in a like fashion by roller three
Fixed, the successively grafting between roller one, roller two and roller three with roller two, convenient for roller one, roller two and roller
Three are disassembled and installed.
The present invention is further arranged to: the fixed frame far from the side of driver's cabin be provided with one abutted with pressure roller scrape
Expect mechanism.
By using above scheme, since pressure roller can occupy a large amount of soil or concrete in the process of work, pressure roller
Deng if soil or concrete are cleared up not in time, the pavement roughness for being easy to cause pressure roller to extrude, scraping mechanism can will be pasted on
Soil or sandstone on pressure roller etc. scrape.
The present invention is further arranged to: the scraping mechanism includes the fixed block for being installed with fixed frame both ends, fixed block phase
To side offer the slot being obliquely installed, a positioning plate is connected in slot jointly, the top bolt of locating piece is fixed
