Abstract
The utility model discloses an actuating-arm turnover mechanism, comprising an oil cylinder base, an oil cylinder, an actuating arm, and a turnover base, wherein one end of the oil cylinder is hinged on the oil cylinder base, and one end of the actuating arm is hinged on the turnover base; and also comprising a main arm and a pull rod, wherein one end of the main arm is hinged with the other end of the oil cylinder, the other end of the main arm is hinged on the turnover base, and one end of the pull rod is hinged on the main arm and the other end is hinged on the actuating arm. Compared with prior art, the utility model has smaller oil cylinder stroke, such that at the maximum stroke position, the oil cylinder also has larger force arm, thereby small oil cylinder thrust is needed; furthermore, the thrust and the stroke are two important parameters of the oil cylinder, thereby the reduction of the thrust and the stroke can result in the remarkable reduction of the cost of the hydraulic system of the mechanism, at the same time, the working time can be saved and the working efficiency can be improved.
Description
Technical field
The present invention relates to a kind of whirling arm mechanism, particularly relate to the tilting mechanism of transportation, loading-unload machine.
Background technology
In transportation, in the loading-unload machine, tumbling of hopper is that upset by working arm realizes that working arm is connected with hopper.Existing working arm switching mechanism constitutes by oil cylinder seat, oil cylinder, working arm and overturning seat are hinged successively, and the push-pull effort of oil cylinder acts directly on the working arm, and the arm that pushes the work forward rotates in bigger angular range.Along with the elongation of oil cylinder, the corner of working arm increases, and the arm of force that oil cylinder acts on the working arm reduces gradually, and at end position, the minimum arm of force is very little, so just requires oil cylinder that bigger thrust is arranged.Therefore, the defective of this mechanism existence is: one, the stroke of oil cylinder is big, thrust is big, can increase the cost of oil cylinder and hydraulic efficiency pressure system; Two, because the stroke of oil cylinder is big, so work efficiency is also lower.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of more time saving and energy saving working arm switching mechanism.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of working arm switching mechanism, comprise oil cylinder seat, oil cylinder, working arm and overturning seat, one end of oil cylinder is hinged on the oil cylinder seat, one end of working arm is hinged on the overturning seat, also comprise big arm and pull bar, an end of described big arm and the other end of oil cylinder are hinged, and the other end of big arm is hinged on the overturning seat; One end of described pull bar is hinged on the big arm, and the other end is hinged on the working arm.
Preferably, described pull bar is hinged on the middle part of big arm.
Preferably, described big arm and working arm are hinged on the diverse location of overturning seat respectively.
The invention has the beneficial effects as follows: owing to increased a big arm and a pull bar, oil cylinder rotates by big arm and the pull bar arm that pushes the work forward, under the working arm flip angle situation identical with overturning couple, the present invention is littler than the oil cylinder stroke of prior art, thereby also has the bigger arm of force at the maximum travel position oil cylinder, therefore the cylinder thrust that needs is little, and thrust and stroke are two important parameters in the oil cylinder, their the hydraulic efficiency pressure system cost that reduces also will reduce greatly mechanism.The shortening of oil cylinder stroke also can be saved the operating time, increases work efficiency.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the scheme drawing of working arm switching mechanism of the present invention at initial condition.
Fig. 2 is the scheme drawing of working arm switching mechanism of the present invention at rollover states.
The specific embodiment
As shown in Figure 1, working arm switching mechanism of the present invention comprises oil cylinder seat 6, oil cylinder 5, big arm 2, overturning seat 1, pull bar 3 and working arm 4, and an end of oil cylinder 5 is hinged on the oil cylinder seat 6, and the other end is hinged with an end of big arm 2; The other end of big arm 2 is hinged on the overturning seat 1.One end of working arm 4 also is hinged on the overturning seat 1, and the other end is connected with hopper 7.One end of pull bar 3 is hinged on the middle part of big arm 2 by bearing pin, and the other end is hinged on the working arm 4.Big arm 2 and working arm 4 are hinged on the diverse location of overturning seat 1, the more close overturning seat 1 of the articulated position of pull bar 3 on working arm 4 respectively.
The present invention can be used on the Transport Machinery with Multi Loading and Unloading Functions, utilizes oil cylinder 5 flexible, drives big arm 2 rotations, simultaneously by the transmission of pull bar 3, makes working arm 4 rotations, thereby drives hopper 7 upsets, plays the function of charging and discharging.The present invention has increased big arm 2 and pull bar 3, in this structure, the arm of force minimum of oil cylinder under initial condition (shown in Figure 1), it is minimum that working arm 4 rotating moment are required, under loading and unloading thing equivalent weight, switching mechanism of the present invention needs littler oil cylinder push-pull effort than common mechanisms.In switching process, the arm of force that oil cylinder 5 acts on the big arm 2 increases gradually, and under the situation of working arm 4 upsets with equal angles, the oil cylinder stroke that switching mechanism of the present invention needs is littler than common, after working arm 4 upsets put in place, as shown in Figure 2, oil cylinder 5 still kept the bigger arm of force.
The invention enables at oil cylinder in the course of the work, the distribution of its push-pull effort and the arm of force is more reasonable, thereby can realize littler push-pull effort and shorter stroke, and it is laborsaving to increase arm of force realization, reduces stroke and realizes saving time.Because thrust and stroke are two important parameters of oil cylinder, their cost that reduces also will reduce greatly the organization hydraulic pressure part.
