Description
Technical field
The utility model belongs to the road building machinery field, relates in particular to a kind of road building machinery that can carry out milling, plastic operation to roadbed, road surface.
Background technology
Pavement milling machine is one of main machine of maintenance of surface construction machinery, is mainly used in asphalt concrete surface layers removings such as highway, urban road and gathers around bag, oil wave, reticulate pattern, rut etc.Old shop layer with pavement milling machine milling damage, re-laying new surface layer is a kind of modernized maintenance process of economy, because its high efficiency, construction technology are simple, milling depth is easy to control, flexible to operation, mobility good, the old material of milling can directly be recycled etc., thereby be widely used in cities and towns town road and the speedway maintenance project.
The general road milling machine by motor, vehicle frame, milling rotor, milling depth adjusting device, Hydraulic Elements, accumulator conveyer, turn to and be and braking system etc. is formed.The milling rotor is the main working parts of milling machine, is made up of milling armature spindle, tool rest and cutter head etc., directly contacts with the road surface, carries out the purpose that work reaches milling by the milling cutter that rotates at a high speed.Generally be provided with self-level(l)ing device on the milling machine, as the milling datum, control two positioning hydraulic cylinders with milling rotor side cover, make given milling depth keep constant; Its hydraulic system is used for driving the rotation of milling rotor, complete machine walking, servicing unit work etc., is generally the separate closed type hydraulic system of many pumps, do not disturb mutually during work and reliability higher; The milling machine that has is installed recliner as required, is used for controlling the gradient of rotor; General large-scale milling machine is all by the accumulator conveyer of being made up of conveyer belt and loading head, and it can be concentrated the bulk cargo that mills out and be sent on the transporting cars of random walk, and the height of conveying arm can be regulated and can swing, to adjust discharge position.
Pavement milling machine primary structure form has two kinds at present: the one, on farm tractor or common loader, install the simple type milling machine that milling attachment constitutes additional, and it is simple in structure, use is flexible, is applicable to the simple milling to the road surface below the moderate strength; The 2nd, large-scale self-propelled milling machine, the frame of self-propelled milling machine is usually by 4 road wheels or crawler belt supporting, milling and planing drum is set below central rack, arrange the milling cutter on the milling and planing drum, front end or rear end in frame are provided with the belt conveyer that gathers materials, in the operation process, the old material that is got off by the milling and planing drum milling is thrown on the feeding belt, thereby goes out from the place ahead or the rear dispatch of frame by the belt conveyer that gathers materials.This milling machine complex structure, functional performance can satisfy the curing requirements of domestic high-grade highway and town road substantially.Though more than two kinds of pavement milling machine structure differences, but the width of their milling and planing drum all is no more than the width of fuselage itself, curb that can't milling frame side, and the time to the curved road surface milling, because milling is rolled itself between milling machine mainframe both sides, when milling machine turned round, the corner certainly existed the local road surface that can not arrived by the milling and planing drum milling, can't a milling be shaped.
The patent No. is 03241907.4, denomination of invention is that the utility model patent of flexible pavement side direction milling machine discloses a kind of flexible pavement side direction milling machine, this milling machine goes forward to be provided with controlling platform in chassis assembly, after be provided with motor, on chassis assembly, be provided with the walking hydraulic motor, gearbox, auxiliary hydraulic pump, the walking hydraulic pump, the working solution press pump, vehicle frame, be provided with the hydraulic jack cantilever in the vehicle frame rear side, homonymy with the hydraulic jack cantilever on vehicle frame is provided with milling facility cantilever, the milling facility that are provided with the milling hydraulic motor are located on the milling facility cantilever, one end and the hydraulic jack cantilever of milling hydraulic jack link, the other end and milling facility link, come the milling curb by the left-external side or the right outside that the milling facility are arranged on vehicle frame, though such milling machine has solved the problem that the conventional milling planer can't the milling curb, but function singleness also need cooperate other pavement milling machine just can finish the milling operation on whole road surface.
The patent No. is US3,767,264 U.S. Patent Publication a kind of milling machine, this milling machine comprises the chassis, road wheel, driver's cabin, drive unit, milling is rolled, installing rack etc. is rolled in milling, wherein, milling is rolled and is rolled installing rack by milling and be installed in chassis below, this milling is rolled installing rack and is provided with the adjustment oil cylinder, can regulate the working depth that milling is rolled by adjusting oil cylinder, simultaneously, milling is rolled between installing rack and chassis and is connected by the rotating shaft that vertically is provided with, be that milling is rolled installing rack and can be rotated around the axis, thereby it is moving to drive the milling lift-over, this rotating shaft is not installed on the center that milling is rolled, roll preceding partially or back partially position on the length direction but be installed on milling, the center that makes milling roll with the rotating shaft to be rotates to milling when rolling center line and the perpendicular position of center chassis line (operating position), and the end that milling is rolled is exposed to outside the chassis, and when the transition transportation, milling is rolled and is then rotated to the position that its center line and center chassis line parallel, and milling is rolled and is positioned at the fuselage width scope fully.This patent is provided with rotates the purpose that milling rolls and is, owing to be subjected to the restriction (fuselage width can not above 3.5 meters) of road transport requirement, the width that existing milling machine milling is rolled can not surpass the width of fuselage, and milling is rolled and is positioned at chassis below all the time in the course of the work, therefore can only carry out milling to the road surface that is positioned at the below, chassis, when running into bend in the milling process, will there be bend one dypass facing cut to dig to roll the zone of can't milling arriving, by being set, do not roll the point of rotation in the milling of center, the end that the milling of rotation back is rolled can stretch out in the left side or the right side on chassis as required, thus the road-surface milling of avoiding running into bend one side when turning round less than situation take place.Though this milling machine has solved the problem that there is the work blind area in bend one dypass face, but because under the duty, center of gravity is rolled in milling and machine gravity is inconsistent, if milling is rolled under the longer situation of length, the problem that then has crank, so this milling machine also can't be realized the wide cut milling.
