Technical field
The utility model relates to a kind of pavement cold recycling machine, specifically a kind of pavement cold recycling machine rotor mechanism.
Background technology
Pavement cold recycling machine is a kind of high efficiency, multiduty construction machinery.Be mainly used in the milling of asphalt concrete pavement and the regeneration of adding the old asphalt pavement after the materials such as pitch, water.Also can be used for the on-the-spot mix-in-place operation of basic unit, bottom Stabilized Soil of the engineerings such as highway, urban and suburban roads, airport, harbour, parking lot.The application of rotor in engineering machinery is often used to the mix of 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, and larger its mix of rotor lifting travel and the milling degree of depth are just larger.
In rotor specific works process, in order to prevent disorderly spattering because of the too fast powder causing of rotating speed and the lump material of rotor, equipment is limited in case, and case and vehicle frame are rigidly connected, and realize 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 transmission of power 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, conventional in the existing mechanism that realizes equipment lifting process is hydraulic means, in rotor both sides, with oil cylinder, stretch to control rotor lifting, in order to guarantee the synchronism of rotor two side cylinder lifting actions, prevent that rotor is to lopsidedness, in prior art, have to adopt multi-connecting-rod mechanism connection is set in rotor both sides, oil cylinder is connected with multi-connecting-rod mechanism, when oil cylinder stretches, by multi-connecting-rod mechanism rotor driven, complete lifting action, two multi-connecting-rod mechanisms are fixed on vehicle frame bilateral symmetry position and guarantee synchronous.The form of structure of this many connecting rods, causes the elevating mechanism of rotor complicated, and cost is high, and assembly technology is also comparatively loaded down with trivial details.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of pavement cold recycling machine rotor mechanism, guarantees the synchronous of rotor both sides elevating ram, and simplifies elevating mechanism, reduces costs, and has also simplified assembly technology simultaneously.
To achieve these goals, a kind of pavement cold recycling machine rotor mechanism of the utility model, comprises vehicle frame, and the running gear arranging on vehicle frame, is arranged on the case on chassis, rotor, elevating ram, transmission device, lift arm and engine power output shaft; Rotor is positioned at case, the hinged a pair of 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 the utility model preferred version, transmission device comprises belt, is arranged on the tension pulley on belt.
As further improvement of the utility model, between two crank block linkages, by rigid connecting shaft, connect as one, the axis of described rigid connecting shaft is parallel with engine power output shaft axis.
Compared with prior art, the elevating mechanism of the utility model rotor has been abandoned oil cylinder and by multi-connecting-rod mechanism, has been driven the structure of rotor, connecting rod and hoist cylinder are separated, directly adopt elevating ram to connect lift arm, oil cylinder is rigidly attached on vehicle frame, for guaranteeing that rotor both sides can be synchronous, lift arm both sides are connected on vehicle frame by two slider-crank mechanisms, the utility model is simplified the elevating mechanism of prior art rotor, saved numerous and diverse linkage, but by more easy slider-crank mechanism, guarantee synchronous, reduce the cost, simplify assembly technology, promoted greatly the competitiveness of product in market.
