In rotor specific works process, in order to prevent that equipment is limited in case because the too fast powder caused of the rotating speed of rotor and lump material disorderly spatter, case and vehicle frame are rigidly connected, and realize the lifting of case by the lifting of vehicle frame.Motor is arranged on 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 but rotor is not connected with other tensile members, to such an extent as to rotor directly contacts with ground, just can't realize the walking of complete machine and the course of work of rotor, lose the manufacturing value of complete machine itself, commonly used in the existing mechanism that realizes the equipment lifting process is hydraulic means, stretch to control the rotor lifting in the rotor both sides with oil cylinder, in order to guarantee the synchronism of rotor two side cylinder lifting actions, prevent that rotor is to lopsidedness, have in prior art to adopt the multi-connecting-rod mechanism connection is set in the rotor both sides, oil cylinder is connected with multi-connecting-rod mechanism, when oil cylinder stretches, complete lifting action by the multi-connecting-rod mechanism rotor driven, 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, cause the elevating mechanism complexity of rotor, and cost is high, and assembly technology is also comparatively loaded down with trivial details.
Summary of the invention
The problem existed for above-mentioned prior art, the invention provides a kind of cold regenerative machine rotor motion mechanism, guarantees the synchronous of rotor both sides elevating ram, and simplify elevating mechanism, reduces costs, and also simplified assembly technology simultaneously.
To achieve these goals, a kind of cold regenerative machine rotor motion of the present invention mechanism, comprise vehicle frame, and the running gear arranged on vehicle frame, be arranged on the case on chassis, rotor, elevating ram, transmission device, lift arm and engine power output shaft;
Rotor is positioned at case, rotor is arranged on the rotor stroke guide rail, the hinged a pair of lift arm of rotor bilateral symmetry, and lift arm one end connects elevating ram, the lift arm other end is connected with engine power output shaft, and engine power output shaft is by the actuator drives rotor; Also comprise rigid connecting shaft, elevating ram is arranged on vehicle frame by cylinder installation seat, between two lift arms, by rigid connecting shaft, links into an integrated entity, and the axis of described rigid connecting shaft is parallel with the engine power output shaft axis.
Preferably, the rotor stroke guide rail is linear pattern.
Further, rotor is equipped with rolling bearing contacting travel guide rail.
Preferably, transmission device comprises belt, is arranged on the tension pulley on belt.
Further, be connected with connecting rod between vehicle frame and case.
Further, be connected with fixed head between vehicle frame and case.
Compared with prior art, the elevating mechanism of rotor of the present invention has been abandoned oil cylinder and has been driven the structure of rotor by multi-connecting-rod mechanism, saved numerous and diverse multi-connecting-rod mechanism, in the elevating mechanism of rotor, directly adopted elevating ram to connect lift arm, oil cylinder is rigidly attached on vehicle frame, for guaranteeing that the rotor both sides can be synchronous, lift arm is rigidly connected by axis, and the present invention simplifies the elevating mechanism of rotor, reduces the cost, simplify assembly technology, promoted greatly the competitiveness of product in market.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of cold regenerative machine rotor motion of the present invention mechanism, comprise vehicle frame 1, the running gear 3 arranged on vehicle frame 1, be arranged on the case 5 on chassis, rotor 6, elevating ram 7, transmission device, lift arm 11, engine power output shaft 12 and rigid connecting shaft 13, rotor 6 is positioned at case 5, rotor 6 is arranged on rotor stroke guide rail 16, the hinged a pair of lift arm 11 of rotor 6 bilateral symmetry, lift arm 11 1 ends connect elevating ram 7, lift arm 11 other ends are connected with engine power output shaft 12, engine power output shaft 12 is by actuator drives rotor 6, elevating ram 7 is arranged on vehicle frame 1 by cylinder installation seat 8, between two lift arms 11, by rigid connecting shaft 13, links into an integrated entity, and the axis of described rigid connecting shaft 13 is parallel with engine power output shaft 12 axis.
