Abstract
The present invention relates to a road roller of an engineering machine. Most common road rollers are circular drum road rollers, the problem that soil is extruded always exists in the process of compaction, the compaction degree of the soil can not be enhanced by reincreasing roll extrusion times after the soil is pressed to certain degree, and the requirements of high-grade highways, high-speed railways and runways can not be satisfied. A circular drum is changed into a pentagon or a triangle in some factories, the density is enhanced, but confined compaction still can not be realized, and however, a mechanism is damaged. The present invention uses the obliquely vibration of a flat plate and two lateral plates to realize the confined compaction of the soil and uses resonance vibration to decrease violent vibration rate so as to realize better compaction effect than that of the existing road rollers.
Description
(1) technical field: the invention belongs to engineering machinery, be a kind of when building highway, railway, house foundation the road roller of compacting soil.
(2) background technology: road roller now commonly used mostly is the circular drum formula, the road roller of producing as domestic each Engineering Machinery Plant and German Bayerische Motorne Werke Aktiengeellschaft.Drum roller exists the problem that the regolith is extruded all the time in compacting process, be pressed onto to a certain degree after more repeatedly roll extrusion can not increase soil compactness, do not satisfy the requirement of high-grade highway, high-speed overload railway, airport runways equivalent-load power.The producer that has changes circular drum into pentagon (as South Africa Lan Pai company) or leg-of-mutton, some dull and stereotyped characteristics is arranged, but still can not realize the compacting of lateral confinement, but causes certain difficulty to rolling, causes the damage of corresponding mechanism.
(3) summary of the invention: the technical problem to be solved in the present invention is that invention a kind ofly can make the soil pressure real density road roller higher than the compacted density of drum roller, to satisfy the needs of modern project foundation construction.The technical scheme that sort this problem out adopts is circle or the polygon cylinder that has replaced present road roller with vibrating plate; vibrating plate is welded by the flat board that is parallel to ground and each acclivitous swash plate of front and back; the effect of swash plate is to make it have enough intensity; the protection internal construction; when advancing not the soil the front push away away; vibrating plate is suspended on vehicle frame soil by each two spring of both sides: the exciting force of vibration plate vibrates is produced by two rollaway type vibrators that are fixed on the vibrating plate; the rollaway type vibrator is formed by circular raceway and by the excitation wheel that hydraulic motor is made circular motion by the crank driving in raceway length; exciting crop rotation circular motion produces centrifugal force; two interior excitation wheels of rollaway type vibrator determine that by gear mechanism synchronous backward rotates; only make during installation with the vertical oblique angle that retreats be the exciting force of making a concerted effort to produce of 20 ° centrifugal force; and making the horizontal component of exciting force is backward for the road roller direction of advance; the centrifugal force of other direction is all cancelled each other; vibrating plate only vibrates in the exciting force direction like this; the vibrating plate both sides respectively have one can not mention the side plate that puts down with vibration plate vibrates by oil cylinder control, and restriction soil is extruded from both sides.
The effect that the present invention is useful can be compared with existing drum roller and pentagon road roller respectively.What drum roller applied soil in compacting process is a fillet distributed force, along with being compacted of soil, the bar shaped distributed force narrows down, all the time exist that the regolith is extruded, the problem of the changing of the relative positions between the subsoil of soil layer attenuation broadening and topsoil and compacting, increase the compactness that the roll extrusion number of times can not increase soil again after being compacted to certain degree, do not satisfy modern project bearing capacity of foundation soil needs.Change cylinder into pentagonal road roller, come down to dull and stereotyped road roller, five blocks of web wheel streams on five limits apply compaction to soil.Advantage is to have only the soil of dull and stereotyped mid portion can not extrude, and might improve than the drum-type compactness, but the soil of dull and stereotyped peripheral part still can be mended and extrudes.Problem is the same with drum-type serious when compacting curb part in subgrade construction, can't compacting.Extrude with side plate restriction when road roller of the present invention is operated in the curb part, the same with the road mid portion can compacting.

(5) specific embodiment: realize that the specific embodiment of the present invention is as assembling shown in total figure figure (1).(1) power set among Fig. 1, (2) transfer case, (3) gearbox, (4) driver's cabin, (5) steering, (6) electrical system, (7) front-wheel, (8) front frame, (9) jolt ramming device, (10) hydraulic system, (11)-and draw-gear, (12) running gear, (13) brakes, (14) back vehicle frame, (15) trailing wheel.Except that other parts of jolt ramming device (9) and existing road roller do not have essence different.Different piece of the present invention is to have replaced present road roller soil to be applied the circle or the polygon cylinder of jolt ramming effect with vibrating plate.Be noted that jolt ramming device (9) especially, it is made up of two rollaway type vibrators, and by fluid motor-driven, the resultant direction of two vibrators is not a vertical but oblique, with the plumb line oblique angle that turns forward be 20 degree.Soil is not extruded forward in the jolt ramming process.The back is the soil of compacting, also can not extrude, and jolt ramming device (9) two bottom sides respectively has a side plate (thin two-wire draws, and has put on the state that comes), is controlled by oil cylinder.
When road roller constructs a road when being operated in by one of curb, biside plate is put down by oil cylinder control, soil can not be extruded from both sides in the jolt ramming process, the back is that the soil of jolt ramming can not be extruded yet, because vibration is backward to the horizontal component of the jolt pressure that soil applies, soil can not extruded from the front, like this below the vibrating plate soil around extrude and all be subjected to side restriction, form said limited compacting on the soil mechanics.It with play honeycomb briquette identical principle arranged: if there is not cylinder to limit extruding of coal from the side, just can not get the honeycomb briquette of rule.The constraint of different just this road roller both sides realize that by side plate the back is that the soil restriction of compacting is extruded, it is that horizontal component by vibrating plate is realized that the soil of front is not extruded.Because mechanics knows that to the calculating of the stress distribution of soil under the vibrating plate proper level component can limit soil and extrude from the front.When road roller not the time by the work of one of curb, the side plate of compacting one side is mentioned, limits it with the soil of compacting and extrudes, and can not stay side plate like this and stitch.
The exciting force that makes vibration plate vibrates also can realize with the rotation of Motor Drive eccentric mass, with the rollaway type vibrator relatively be that shaft strength is big, should in the small-power road roller, adopt.
Make the exciting force of vibration plate vibrates can realize that also the cylinder of drum roller commonly used up-down vibration when rolling realizes with hydraulic system now with hydraulic system or electromagnetic force.
The amplitude of vibrating plate of the present invention can be regulated, and has better handling capacity when transferring large amplitude, otherwise the soil of front can be pushed away away.This machine belongs to the machinery that utilizes vibration, so excited frequency should be approaching with the intrinsic frequency of vibrational system, utilizes resonance principle to increase amplitude, reduces exciting power.
