Abstract
The utility model relates to vehicles, in particular to an altitude lifting mechanism for an aircraft tractor cab, which is provided with a frame, a hydraulic cylinder and a cab. The altitude lifting mechanism is characterized in that lower arms are respectively arranged on two sides of the lower end of the cab, upper arms are respectively arranged on two sides of the upper portion of the cab, one end of each upper arm is hinged with the frame, the other ends of the upper arms are hinged with the cab, one end of each lower arm is hinged with the frame, the other ends of the lower arms are hinged with the cab, and thereby the upper arms, the frame, the lower arms and the cab form a parallelogram connecting rod mechanism, and further, one end of the hydraulic cylinder is hinged with the frame, the other end of the hydraulic cylinder is hinged with the upper arms. Due to the structure of the altitude lifting mechanism, lifting height of the cab is increased, and the altitude lifting mechanism has the advantages of simple structure, convenience and simplicity in assembly, no wear, small lifting resistance, fine smoothness and the like.
Description
Technical field
The utility model relates to vehicle, the high-order lifting mechanism of specifically a kind of aircraft towing operator's compartment.
Background technology
As everyone knows, the operator's compartment of many vehicles or equipment all needs elevating function, as: the large-tonnage aircraft towing is in the process of butt joint aircraft, chaufeur must be able to be seen the position of hauling hook clearly, for this reason, when the butt joint rear towing hook, require operator's compartment can be raised to certain altitude, increase driver's seat; When butt joint front haulage hook, operator's compartment must drop to very low, prevents that operator's compartment is too high and runs into aircraft, and can see the front haulage hook clearly.The tradition cab lift all is to adopt guide rail guiding fluid cylinder to drive the lifting that realizes operator's compartment, and the shortcoming of this up-down mode is the height that adjustable height is subject to car body, and guide rail matching requirements precision is higher, and long term wear is damaged easily, not easy-maintaining.And the high-order lifting mechanism of the operator's compartment that the utility model proposes, owing to adopt parallelogram linkage, simple in structure, easy to assembly simple and direct, precision guarantees easily, by lever principle the adjustable height of operator's compartment is further increased, because it is hinged that mechanism all adopts, and do not have the existence of sliding pair, not wearing and tearing, the lifting resistance is little, and ride comfort is good.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, increase adjustable height, easy to assembly simple and direct, do not have wearing and tearing, the lifting resistance is little, ride comfort is a good high-order lifting mechanism of aircraft towing operator's compartment.
The technical scheme that its technical matters that solves the utility model adopts is:
The high-order lifting mechanism of a kind of aircraft towing operator's compartment, be provided with vehicle frame, fluid cylinder and operator's compartment, it is characterized in that both sides, operator's compartment lower end are respectively equipped with underarm, the both sides, top are respectively equipped with upper arm, and upper arm one end and vehicle frame are hinged, the other end and operator's compartment are hinged, underarm one end and vehicle frame are hinged, and the other end and operator's compartment are hinged, and make upper arm, vehicle frame, underarm and operator's compartment form the connecting rod mechanism of parallelogram, fluid cylinder one end and vehicle frame are hinged, and the other end and upper arm are hinged.
The utility model has increased the cab lift height owing to adopt said structure, have simple in structure, easy to assembly simple and direct, do not have wearing and tearing, advantage such as the lifting resistance is little, ride comfort is good.
Description of drawings
Fig. 1 is a theory of machines scheme drawing of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the structural representation that the operator's compartment in the utility model rises, descends.
Reference numeral: 1 is vehicle frame, and 2 is upper arm (ab connecting rod), and 3 is fluid cylinder, and 4 is operator's compartment, and 5 is underarm (cd connecting rod).
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in drawings, the high-order lifting mechanism of a kind of aircraft towing operator's compartment, be provided with vehicle frame 1, fluid cylinder 3 and operator's compartment 4, it is characterized in that both sides, operator's compartment 4 lower end are respectively equipped with underarm 5, the both sides, top are respectively equipped with upper arm 2, upper arm 2 one ends and vehicle frame 1 are hinged, the other end and operator's compartment 4 tops are hinged, underarm 5 one ends and vehicle frame 1 are hinged, the other end and operator's compartment 4 lower ends are hinged, make upper arm 2, vehicle frame 1, underarm 5 and operator's compartment 4 form the connecting rod mechanism of parallelogram, fluid cylinder 3 one ends and vehicle frame 1 are hinged, and the other end and upper arm 2 are hinged.
Among Fig. 1, a, c, f is a upper arm 2, underarm 5 and the fluid cylinder 3 fixedly hinge on vehicle frame 1, relative vehicle frame 1 invariant position, b, d is upper arm 2 and the fixedly hinge of underarm 5 on operator's compartment 4, relative operator's compartment 4 invariant positions, e is the hinge of fluid cylinder 3 and upper arm 2, the relative upper arm in position 2 is constant, b ', d ', e ' is that operator's compartment 4 rises back b, d, the terminating point of e, ab, bd, cd, ac constitutes parallelogram linkage, ab=cd, ac=bd, according to the motion analysis of theory of machines parallelogram connection-rod, fluid cylinder 3 promotes upper arm 2ab and rotates around a point, underarm 5cd rotates around the c point, bd remains with ac parallel in motion process, since relative vehicle frame 1 invariant position of ac, relative operator's compartment 4 invariant positions of bd, promote in the parallelogram motion process at fluid cylinder 3, operator's compartment 4 can keep horizontal lifting.
Below in conjunction with specific embodiment, the high-order lifting mechanism of aircraft towing operator's compartment of the present utility model is described further, to help to understand content of the present utility model.
It is parallel and equal that upper arm 2 and underarm 5 remain, and fluid cylinder 3 promotes upper arm 2 rotations, and according to the motion principle of parallelogram linkage, underarm 5 rotate simultaneously, makes upper arm 2 and underarm 5 drive simultaneously that operator's compartment 4 levels rise or decline.
The utility model has increased the cab lift height owing to adopt said structure, have simple in structure, easy to assembly simple and direct, do not have wearing and tearing, advantage such as the lifting resistance is little, ride comfort is good.
