Detailed description of the invention
Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is carried out clear, complete description, it is clear that described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained on the premise of not making creative work, broadly fall into the scope of protection of the invention.
As shown in Figure 2, a kind of revolution material-feeding mechanism, including 1, jib 2 of turntable and an arm support oil cylinder 3, first end of a number jib 2 is hinged with turntable 1, the two ends of a number arm support oil cylinder 3 are hinged with 1, jib 2 of turntable respectively, wherein: when jib 2 horizontal positioned, an arm support oil cylinder 3 and backward the formed angle a with the pin joint between an arm support oil cylinder 3 and a jib 2 as summit of level are not more than 90 degree.Wherein, jib 2 horizontal positioned, i.e. No. one jib 2 is in initial horizontal rounding state.Level is backward is the direction being horizontally directed to a jib 2 second end by this pin joint, and when jib 2 horizontal positioned and the sensing tailstock, level is backward is the direction being horizontally directed to the concrete mixer tailstock.
As shown in Figure 3, Fig. 3 is the original state that a jib 2 is in horizontal positioned, wherein S1 is the initial length (or claiming installation length) of an arm support oil cylinder 3, L1 is the thrust arm of force of next number arm support oil cylinder of this state 3, it is illustrated in figure 4 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 arm support oil cylinder of this state 3.The stroke of a number arm support oil cylinder 3 is S2-S1.
Visible, said structure based on the embodiment of the present invention, the end that the closer jib 2 of pin joint of a number arm support oil cylinder 3 and a jib 2 is hinged with turntable 1, according to geometrical calculation, during operation, a number jib 2 is turned to vertical state by level, and the length of arm support oil cylinder 3 elongation, i.e. the stroke of an arm support oil cylinder 3 has had obvious reduction relative to the stroke of an arm support oil cylinder in existing mechanism.General, length of oil cylinder should be greater than oil cylinder stroke, and for the oil cylinder of different length, the difference between length of oil cylinder and oil cylinder stroke to reach certain numerical value.So, owing to arm support oil cylinder 3 stroke in the said structure of the embodiment of the present invention is less, the arm support oil cylinder 3 that length is shorter can also be selected accordingly.
It addition, by the reasonable setting of each pin joint position, the initial arm of force of bigger arm support oil cylinder 3 can be increased.Preferably, as shown in Figure 2, the pin joint of a number arm support oil cylinder 3 with turntable 1 can be arranged on more rearward position, increase the distance (in figure, dotted portion is the shape of prior art intermediate station) of this pin joint to a No. jib 2 and turntable 1 pin joint, and to make angle a recited above be the acute angle close to 90 degree.By 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, thus reduces the requirement to arm support oil cylinder 3 cylinder diameter, it is also possible to reaches to reduce the purpose of arm support oil cylinder 3 volume and weight.
Preferably, when jib 2 horizontal positioned, the pin joint between an arm support oil cylinder 3 and a jib 2 is higher than the pin joint between a jib 2 and turntable 1.Use this structure, during a jib 2 launches, can to a certain degree increase the arm of force of bigger arm support oil cylinder 3 thrust.
Preferably, the first end of a jib 2 is bent downwardly relative to the main body of a jib 2.If 3 to number jib of an arm support oil cylinder 2 arranged is smaller with the distance of turntable 1 pin joint, during a jib 2 launches, a number arm support oil cylinder 3 may produce with this pin joint interferes, and needs to arrange more complicated articulated structure to avoid this to interfere.But, by the setting of warp architecture, the distance between an arm support oil cylinder 3 and this pin joint during whole expansion can be increased, the arm of force of (state of jib 2 horizontal positioned) arm support oil cylinder 3 under original state can also be increased simultaneously.
And, setting by this reclinate structure, ensure jib 2 horizontal component not with the component interference at pump truck rear portion on the premise of (height keeping number jib 2 horizontal component does not reduces), the pin joint of a jib 2 with turntable 1 can be moved down certain altitude (depending on this height is according to the degree bent).Accordingly, turntable 1 can select the most relatively low articulated stand, such that it is able to reduce the weight of turntable, to reduce the energy expenditure in turntable 1 rotation process.
Preferably, as it is shown in figure 5, the upper edge of a jib 2 is provided with protruding 4, an arm support oil cylinder 3 and a jib 2 are articulated with at protruding 4.Protruding 4 can be arranged on the upper edge of the bending section of a jib 2, an arm support oil cylinder 3 and a jib 2 be articulated with this at protruding 4, and the height of pin joint is higher than the upper edge of jib 2 horizontal part.In certain situations it is desirable to increase the degree of crook of bigger jib 2 bending section, with on the premise of a jib 2 horizontal component height is constant, reduces the height with turntable 1 pin joint further, thus reduce the height of turntable 1.But in this case, the stroke of an arm support oil cylinder 3 may slightly increase, the length of a corresponding arm support oil cylinder 3 also can increase.Use this structure, can be on the premise of keeping a jib 2 horizontal component height constant, the arm support oil cylinder 3 that installation length is the most longer, so that the stroke of an arm support oil cylinder 3 can meet requirement, and, it is not necessary to change the angle of an arm support oil cylinder 3, cause the arm of force to reduce.
The embodiment of the present invention additionally provides a kind of concrete mixer, including turning round material-feeding mechanism as above.
The revolution material-feeding mechanism that embodiments of the invention are provided, including turntable, a number jib and an arm support oil cylinder, first end of a number jib is hinged with turntable, the two ends of a number arm support oil cylinder respectively with turntable, a number jib is hinged, when a jib horizontal positioned, a number arm support oil cylinder and backward the formed angle with the pin joint between an arm support oil cylinder and a jib as summit of level are not more than 90 degree, described level is backward is the direction being horizontally directed to jib second end by this pin joint, thus, needed for a number jib is pushed into vertical state by level by a number arm support oil cylinder, stroke shortens relative to prior art, and then the length of oil cylinder can be reduced, volume and weight, and, the contraction in length of oil cylinder can improve the stability of revolution material-feeding mechanism.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
