Description
Technical field
The present invention relates to a kind of pavement cold recycling machine, specifically a kind of rotor mechanism of pavement cold recycler.
Background technology
Pavement cold recycling machine is a kind of high efficiency, multiduty construction machinery.Be mainly used in the regeneration of the milling of asphalt concrete pavement and the old asphalt pavement after adding the material such as pitch, water.Also can be used for the basic unit of the engineerings such as highway, urban and suburban roads, airport, harbour, parking lot, the on-the-spot mix-in-place operation of bottom Stabilized Soil.The application of rotor in engineering machinery is often used to the mix to powder and the milling to flexible pavement, it is the important motion of cold regenerative machine, the mix degree of depth of rotor and the milling degree of depth rely on the lifting of rotor to realize, rotor lifting travel its mix larger and the milling degree of depth larger.
In rotor specific works process, in order to prevent the too fast powder that causes of the rotating speed because of rotor and lump material from disorderly spattering, equipment is limited in case, and case and vehicle frame are rigidly connected, and is realized the lifting of case by the lifting of vehicle frame.Motor is arranged in frame chassis, and its power output shaft is parallel with rotor axis, and power transmission relies on belt or other transmission devices to realize.
If rotor can not be connected by tensile member with other, to such an extent as to rotor directly contacts with ground, just cannot realize the walking of complete machine and the course of work of rotor, lose the manufacturing value of complete machine itself, it is existing that to realize in the mechanism of equipment lifting process conventional be hydraulic means, stretch at rotor both sides oil cylinder and control rotor lifting, in order to ensure the synchronism of rotor two side cylinder lifting action, prevent rotor to lopsidedness, have in prior art to adopt and multi-connecting-rod mechanism connection is set in rotor both sides, oil cylinder is connected with multi-connecting-rod mechanism, when oil cylinder stretches, lifting action is completed by multi-connecting-rod mechanism rotor driven, two multi-connecting-rod mechanisms are fixed on vehicle frame bilateral symmetry position and ensure synchronous.The form of structure of this multi link, cause the elevating mechanism of rotor complicated, cost is high, and assembly technology is also comparatively loaded down with trivial details.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of rotor mechanism of pavement cold recycler, ensure the synchronous of rotor both sides elevating ram, and simplify elevating mechanism, reduce costs, also simplify assembly technology simultaneously.
To achieve these goals, a kind of rotor mechanism of pavement cold recycler of the present invention, comprises vehicle frame, the running gear that vehicle frame is arranged, is arranged on the case on chassis, rotor, elevating ram, transmission device, lift arm and engine power output shaft; Rotor is positioned at case, hinged a pair lift arm of rotor bilateral symmetry, and lift arm one end connects elevating ram piston end, and the lift arm other end is connected with engine power output shaft, and engine power output shaft is by actuator drives rotor; Also comprise crank block linkage, elevating ram cylinder body end is arranged on vehicle frame, and two lift arms are connected on vehicle frame by two crank block linkages.
As preferred version of the present invention, transmission device comprises belt, the tension pulley be arranged on belt.
As a further improvement on the present invention, connected as one by rigid connecting shaft between two crank block linkages, the axis of described rigid connecting shaft and engine power output shaft axis being parallel.
Compared with prior art, the elevating mechanism of rotor of the present invention has abandoned oil cylinder drives rotor structure by multi-connecting-rod mechanism, connecting rod and hoist cylinder are separated, direct employing elevating ram connects lift arm, oil cylinder is rigidly attached on vehicle frame, for ensureing that rotor both sides can be synchronous, lift arm both sides are connected on vehicle frame by two slider-crank mechanisms, the elevating mechanism of prior art rotor simplifies by the present invention, eliminate numerous and diverse linkage, but ensured synchronous by more easy slider-crank mechanism, reduce the cost, simplify assembly technology, improve the competitiveness of product in market greatly.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of rotor mechanism of pavement cold recycler of the present invention, comprise vehicle frame 1, the running gear 3 that vehicle frame 1 is arranged, is arranged on the case 5 on chassis, rotor 6, elevating ram 7, transmission device, lift arm 11 and engine power output shaft 12; Rotor 6 is positioned at case 5, hinged a pair lift arm 11 of rotor 6 bilateral symmetry, and lift arm 11 one end connects elevating ram 7 piston end, and lift arm 11 other end is connected with engine power output shaft 12, and engine power output shaft 12 is by actuator drives rotor 6; Also comprise crank block linkage 8, elevating ram 7 cylinder body end is arranged on vehicle frame 1, and two lift arms 11 are connected on vehicle frame 1 by two crank block linkages 8.
Transmission device can be other suitable kind of drive, such as Chain conveyer, and the present invention preferably adopts V belt translation, and transmission device comprises belt 10, the tension pulley 9 be arranged on belt 10.
During work, staff operates in driver's cabin, engine start, engine power output shaft 12 is rotated through belt 10 rotor driven 6 and carries out milling action, now rotor 6 both sides elevating ram 7 piston stretches out, rotor driven 6 is driven to move down by lift arm 11, belt 10 together declines with rotor 6, rotor 6 and earth surface carry out milling work, milling completes elevating ram 7 and shrinks, lift arm 11 drives rotor driven 6 to move up, belt 10 together rises with rotor 6, rotor 6 departs from ground, milling terminates, because both sides lift arm 11 is connected on vehicle frame 1 by two crank block linkages 8, ensure that the synchronism of the both sides elevating ram 7 be connected with lift arm 11.
The elevating mechanism of rotor of the present invention has abandoned oil cylinder drives rotor structure by multi-connecting-rod mechanism, original multi-connecting-rod mechanism and hoist cylinder are separated, direct employing elevating ram 7 connects lift arm 11, oil cylinder is rigidly attached on vehicle frame 1, lift arm 11 both sides are connected on vehicle frame 1 by two crank block linkages 8, ensure that rotor 6 both sides can be synchronous.
Be connected on the basis of vehicle frame 1 at two crank block linkages 8, as a further improvement on the present invention, connected as one by rigid connecting shaft 13 between two crank block linkages 8, the axis of rigid connecting shaft 13 and engine power output shaft 12 axis being parallel, better can ensure synchronism, the stability of elevating ram 7 action.
