Abstract
The utility model relates to a hydraulic lifting road roller, which is characterized in that firstly, the hydraulic lifting road roller can be served as an attachment to be arranged on all road rollers with hydrostatic steering to make the road shoulder and slope back-filling compacting work or the bridge stage back back-filling compacting work, and the structure and performance of the original road roller are not broken. Secondly, the hydraulic lifting road roller is provided with adjustable constant pressure copying compacting ability linear pressure which can reach 400N/cm. Thirdly, the hydraulic lifting road roller is only needed to be lifted but is not needed to be dismounted from the host machine when not used.
Description
The utility model belongs to the curb compaction apparatus of attaching on a kind of self-propelled roller.This device also can be used for the compacting operation of side slope and bridges and culverts back filling behind abutment engineering.
In the road foundation construction, the operation of can't keeping to the side of large-scale compacting machinary, curb and side slope can not get effective compacting.For this reason, the basis in the effective width that guarantees to design in the mode of widening roadbed more than in the construction is able to compacting.Like this, increased construction cost greatly, and the curb of outer and side slope position are easy to sink because soft under flood erosion.
The purpose of this utility model is a kind of compaction apparatus of design, and it can be effectively applied to the compacting operation of road curb and side slope.This installation cost is low, the efficient height, and construction technology is simple, can adapt to the needs of large-scale engineering machinery construction.
Overall structure of the present utility model is by rail bracket, hoist cylinder, and turning rolls, roller, connector, several parts of hydraulic control system are formed.
Structure and embodiment to this device is described further below in conjunction with accompanying drawing.Accompanying drawing 1 is the structural principle and the scheme of installation of the designed curb compaction apparatus of the utility model, among the figure: the 1-rail bracket; The 2-hoist cylinder; The 3-turning rolls; The 4-roller; 5-rail bracket gusset piece; The 6-attachment bolt; 7-main frame compacting wheel carrier; The 8-clamping plate.Rail bracket gusset piece 5 is one with rail bracket 1 weldering, by 4 attachment bolts 6 and clamping plate 8 this curb compaction apparatus and main frame compacting wheel carrier 7 are combined as a whole, be suspended on the side of main frame near side slope, when the main frame compacted subgrade, hoist cylinder 2 descends, turning rolls 3 stretches out, and makes roller 4 press down curb, can carry out the curb compacting operation that main frame can't keep to the side under main frame drives.On turning rolls 3 and the rail bracket 1 track is arranged respectively, this track no-float, only allow turning rolls 3 to move up and down and retrain moving of other direction along the track of rail bracket 1.This track can be that rectangular configuration also can be by angle steel as v-shaped structure by channel-section steel weldering, also can be by inside and outside pipe as circular configuration, but must prevent that turning rolls 3 from rotating along the additional slide key of the direction that moves up and down during circular configuration.Roller 4 desirable cylinder wheels are with compacting curb and bridges and culverts back filling behind abutment, and also desirable conical wheel is with the compacting side slope, and the conical wheel tapering should adapt with its angle of gradient.Roller widths is got 150～300mm and is advisable, and body diameter is got 200～250mm and is advisable.Linear pressure is got 300～400N/cm and is advisable (being equivalent to the quiet stone roller road roller of 8～10T compaction capacity).
The compaction force adjustment of this curb compaction apparatus and lifting location etc. are controlled by hydraulic control system.Accompanying drawing 2 is hydraulic control system schematic diagrams of the designed curb compaction apparatus of the utility model, among the figure: the 9-overflow valve; 10 1 solenoid operated directional valves; 11-single channel hydraulic control one-way valve; The 12-oil sump tank.
This device control fluid is taken from the oil return of main frame hydraulic steering gear, and during compacting operation, it is that oil cylinder 2 stretches out work that solenoid operated directional valve 10 is got position, a left side, and this moment, the roller compaction force was the adjusting pressure decision of oil cylinder downforce by overflow valve 9.This kind operating mode overflow valve 9 is for often opening overflow, and the pressure by its generation makes the roller compacting soil.Influence original host fluid-link steering ability in order not make because of setting up of this curb compaction apparatus, and avoid making system's heating too high because of overflow valve 9 Chang Yiliu, the adjusting pressure of overflow valve is advisable to be no more than 1.5～2.0MPa, and with the corresponding rise 1.5～2.0MPa of original host steering hydraulic system overflow valve pressure.
The linear pressure size that this curb compacting is rolled is adjusted by overflow valve 9, in case set up then be a permanent linear pressure profiling compaction apparatus, when curb bankets deficiency when having the hole recessed, roller is stretched down automatically, when banketing too much or projection such as stone is arranged, contracts on roller is automatic.
Need not the curb compaction apparatus during work, solenoid operated directional valve 10 right position work, oil cylinder 2 withdrawals are risen the back solenoid operated directional valve with roller and are put meta, and the control one way valve 11 that overflows is formed a locking oil circuit with oil cylinder 2, and roller can not descend automatically because of the deadweight effect.The direct oil sump tank 12 of original host hydraulic steering gear oil return simultaneously makes the oil circuit reinstatement.
The utility model has following advantage:
1. can be loaded on any road roller with fluid-link steering as a separate accessories, Easy for installation, use simply, and do not change former machine performance and structure.
2. this device, is mentioned and is got final product when not using in case installation need not be unloaded.
3. this device has constant voltage profiling ability, and compaction capacity is reliable, and is strong to the out-of-flatness adaptive faculty of curb.
4. change the difformity roller, can carry out different work.
5. simple in structure, with low cost, use reliable.
