The specific embodiment
To combine the accompanying drawing among the present invention below, the technical scheme among the present invention is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the present invention protects.
As shown in Figure 2; A kind of revolution material-feeding mechanism; First end and the turntable 1 that comprise turntable 1, jib 2 and 3, numbers jibs 2 of an arm support oil cylinder are hinged, and the two ends of an arm support oil cylinder 3 are hinged with turntable 1, a jib 2 respectively; Wherein: when jib 2 horizontal positioned, after arm support oil cylinder 3 and the level to formed be that the angle a on summit is not more than 90 degree with the pin joint between arm support oil cylinder 3 and the jib 2.Wherein, jib 2 horizontal positioned, promptly a jib 2 is in initial horizontal rounding state.After the level to being the direction of pointing to jib 2 second ends by this pin joint level, jib 2 horizontal positioned and when pointing to the tailstock, after the level to being the direction that level is pointed to the concrete mixer tailstock.
As shown in Figure 3; Fig. 3 is the original state that jib 2 is in horizontal positioned; Wherein S1 is the initial length (or claiming installation length) of an arm support oil cylinder 3, and L1 is the thrust arm of force of next number of state arm support oil cylinder 3 for this reason, is illustrated in figure 4 as a jib 2 and is in vertical deployed condition; Wherein S2 is the termination length of an arm support oil cylinder 3, and L2 is the thrust arm of force of next number of state arm support oil cylinder 3 for this reason.The stroke of an arm support oil cylinder 3 is S2-S1.
It is thus clear that; Based on the said structure of the embodiment of the invention, the pin joint of an arm support oil cylinder 3 and a jib 2 near the hinged end of jib 2 and turntable 1, can be known according to geometrical calculation; In the process of operation; No. one jib 2 turns to vertical state by level, the length of arm support oil cylinder 3 elongations, and promptly the stroke of an arm support oil cylinder 3 has had significantly with respect to the stroke of an arm support oil cylinder in the existing mechanism and has reduced.General, oil cylinder length should be greater than oil cylinder stroke, and for the oil cylinder of different length, the difference between oil cylinder length and the oil cylinder stroke will reach certain numerical value.So,, also can select short arm support oil cylinder 3 of length accordingly because arm support oil cylinder 3 strokes in the said structure of the embodiment of the invention are less.
In addition, through the reasonable setting of each pin joint position, can increase the initial arm of force of bigger arm support oil cylinder 3.Preferably; As shown in Figure 2; Can the pin joint of arm support oil cylinder 3 and turntable 1 be arranged on the position after comparatively leaning on; Increase the distance (dotted portion is the shape of prior art intermediate station among the figure) of this pin joint to one jib 2 and turntable 1 pin joint, and make angle a recited above be acute angle near 90 degree.Through this structure; Can effectively increase the initial arm of force of bigger arm support oil cylinder 3; The initial thrust of a corresponding arm support oil cylinder 3 just can reduce, thereby has reduced the requirement to arm support oil cylinder 3 cylinder diameters, also can reach the purpose that reduces arm support oil cylinder 3 volume and weights.
Preferably, when jib 2 horizontal positioned, the pin joint between arm support oil cylinder 3 and the jib 2 is higher than the pin joint between jib 2 and the turntable 1.Adopt this structure, in the process of jib 2 expansion, can to a certain degree increase the arm of force of bigger arm support oil cylinder 3 thrusts.
Preferably, first end of a jib 2 is with respect to the main body downwarping of a jib 2.When if the distance of 3 to jibs of an arm support oil cylinder 2 that are provided with and turntable 1 pin joint is smaller; In the process of jib 2 expansion; An arm support oil cylinder 3 may produce with this pin joint interferes, and needs to be provided with complicated articulated structure to avoid this interference.Yet, through the setting of warp architecture, can increase in the whole expansion process distance between arm support oil cylinder 3 and this pin joint, also can increase the arm of force of (states of jib 2 horizontal positioned) arm support oil cylinder 3 under the original state simultaneously.
And; Setting through this reclinate structure; Guaranteeing under the prerequisite that jib 2 horizontal component are not interfered with the parts at pump truck rear portion (keeping the height of jib 2 horizontal components not reduce), can the pin joint of jib 2 and turntable 1 moved down certain altitude (this highly decides according to the degree of bending).Accordingly, can select highly lower articulated stand on the turntable 1, thereby can reduce the weight of turntable, to reduce the energy consumption in turntable 1 rotation process.
Preferably, as shown in Figure 5, the upper edge of a jib 2 is provided with protruding 4, numbers arm support oil cylinder 3 and a jib 2 is articulated in protruding 4 places.Can protruding 4, numbers arm support oil cylinder 3 be set in the upper edge of the bend of a jib 2 and a jib 2 is articulated in this convexity 4 places, and the height of pin joint is higher than the upper edge of jib 2 horizontal parts.In some cases, need increase the degree of crook of bigger jib 2 bends,, further reduce the height with turntable 1 pin joint, thereby reduce the height of turntable 1 with under the constant prerequisite of jib 2 horizontal component height.Yet in this case, the stroke of an arm support oil cylinder 3 may slightly increase, and the length of a corresponding arm support oil cylinder 3 also can increase to some extent.Adopt this structure, can keep under the constant prerequisite of jib 2 horizontal component height the arm support oil cylinder 3 that installation length is longer slightly; So that the stroke of an arm support oil cylinder 3 can meet the demands; And, need not to change the angle of an arm support oil cylinder 3, cause the arm of force to reduce.
The embodiment of the invention also provides a kind of concrete mixer, comprises aforesaid revolution material-feeding mechanism.
The revolution material-feeding mechanism that embodiments of the invention provided; Comprise turntable, a jib and an arm support oil cylinder, first end and the turntable of a jib are hinged, and the two ends of an arm support oil cylinder are hinged with turntable, a jib respectively; When a jib horizontal positioned; After arm support oil cylinder and the level to formed be that the angle on summit is not more than 90 degree with the pin joint between arm support oil cylinder and the jib, after the said level to being the direction of pointing to jib second end by this pin joint level, thereby; An arm support oil cylinder is pushed into the required stroke of vertical state with a jib by level and shortens with respect to prior art; And then can reduce length, the volume and weight of oil cylinder, and the contraction in length of oil cylinder can improve the stability of revolution material-feeding mechanism.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
