Abstract

The utility model discloses a vibrated road roller, which can effectively improving the defects that the inductive depth is shallow via vibrated compaction, main parameters can not be adjusted, and the conversion of compacting function is complicated. The vibrated road roller of the utility model is changed with a novel rolling wheel. The rolling wheel is characterized in that an independent vibrator is used for driving the rolling wheel to vibrate or oscillate, and the main parameters of compaction can be conveniently adjusted to satisfy the optimum matching of two compacting work conditions. The utility model has the advantages of novel structure, easy fabrication, low cost, simple conversion of compacting work conditions, favorable compacting quality, energy saving, little environmental pollution, etc.

Description

Vibrated roller

The utility model relates to a kind of compacting machinary, particularly a kind of vibratory and oscillation roller with vibratory compaction and two kinds of functions of oscillation compaction.

At present both at home and abroad compacting machinary is except that quiet stone roller road roller and vibratory roller, early eighties, the take the lead in oscillatory roller of research and utilization soil mechanics alternation shearing strain principle of Sweden Qiao Dai Namike (Geodynamic) company; The oscillatory roller of West Germany Hamm company in 1984 is put on market in the first batch; Janpanese sake Jingyan County made N3 type oscillatory roller in 1987.Domesticly also began development successively in 1986 about universities and colleges and research institution, in respect of the YD10 type oscillatory roller of Xi'an Gong Lu institute and Xuzhou Engineering Machinery Plant joint research and development; The YZD2 type oscillatory roller and the Harbin School of Architecture ﹠ Civil Engineering " research of oscillatory roller model equipment " of Changsha building machinery research institute and the development of Handan Construction Machinery Plant.The oscillatory roller of development or model are taken turns both at home and abroad, all take to drive two parallel perforation eccentric mass axles simultaneously and do rotation at a high speed with central actuating shaft, the form of structure of excitation roller vibration, all tests all show: though that oscillation compaction has a top layer compaction quality is good, save the energy, reduce vibration nuisance, improve advantages such as driver's operation condition; But the roller body manufacturing is difficulty relatively, the operation of compacting change working also bothers, major parameters such as dead line pressure that the more important thing is road roller are unadjustable, can't satisfy the different requirements of two kinds of compacting mechanisms of vibration and oscillation simultaneously, cause the influence of oscillation compaction induction depth as shallow to be applied.

The purpose of this utility model provides a kind of novel vibratory and oscillation roller; It can improve present oscillation compaction induction depth as shallow, the uncontrollable defective of principal parameter effectively, and can realize vibration and the conversion of oscillation compaction function easily.

For achieving the above object, the utility model vibratory and oscillation roller is realized by novel structure roller that vibratory roller is changed the outfit; Roller is that hollow is closed, establishes liquid injection port, can strengthen dead line pressure to wherein water filling or liquid during oscillation compaction, and the oscillation compaction induction degree of depth is increased; Two groups of vibrators that symmetry is installed on the roller former drive rotation in the same way by hydraulic motor by central axis, and the direction of rotation that changes hydraulic motor can make two groups of vibrator eccentric mass be in homophase or anti-phase position respectively, thus vibration of excitation roller or vibration.

In conjunction with the accompanying drawings novel roller is described in further detail.

Accompanying drawing 1 is the utility model roller structure schematic diagram.

Accompanying drawing 2 is the utility model roller vibrator (11) structural representations.

Accompanying drawing 3 is the utility model roller vibrator (7) structural representations.

Roller is installed in the front-wheel framework, and framework is through rubber damping piece (4), and is supported on the outer former (10) of roller body by bearing (6) and bearing support, so roller body can freely roll in framework.

Roller inner chamber by cylinder (12) and former formations such as (9) is that hollow is closed, and liquid injection port (13) is set, and vibration rolls Shi Kexiang wherein water filling or liquid, to regulate roller dead line pressure.

The vibration of roller or vibration are by fluid motor-driven, hydraulic motor drives central axis (1) rotation through spline housing (5), central axis is supported on the wheel body former (9) by bearing (2), when central axis rotates, drive four vibrators (7) that are installed on the former (9) simultaneously by the synchronizing jugged belt wheels in two ends (3) and through four synchronous cog belts (8), (11) eccentric mass axle (19), (14) are done synchronous high-speed rotation in the same way, thus vibration of excitation roller or vibration.

In vibrator (11), eccentric mass axle (14) is welded by axle and eccentric mass, is supported on the housing (16) by bearing (15), and axle head is connected with synchronizing jugged belt wheel (17) with key (18).

In vibrator (7), eccentric mass axle (19) is supported on the housing (16) by bearing (15), axle head is connected with drive sleeve (21) with key (20), synchronizing jugged belt wheel (22) is all made the driving pawl with angle 90 degree with drive sleeve (21), when the commutation rotation, its driving pawl just can be stirred drive sleeve (21) driving pawl after synchronizing jugged belt wheel (22) needed empty turnback, thereby drive eccentric mass axle (19) rotates thereupon, so difference along with hydraulic motor rotation aspect, the two groups of vibrators (7) that driven, (11) eccentric mass present position is also just different, when two groups of eccentric mass are in the homophase position and rotate at a high speed, the vibration of excitation roller realizes vibratory compaction; When two groups of eccentric mass are in anti-phase position and rotate at a high speed, produce sinusoidal wave alternation couple, the vibration of excitation roller realizes oscillation compaction.
