The core of the utility model is that a kind of fixedly capstan head that is used for engineering machinery is provided, make this fixedly capstan head when carrying each supporting leg and turntable, also have simple in structure, volume is little, shock resistance and the good advantage of thermal diffusivity.Another core of the utility model is that a kind of engineering machinery that comprises the said fixing capstan head is provided.
In order to make those skilled in the art understand the technical scheme of the utility model better, the fixedly capstan head with concrete mixer is an example below, in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Please refer to Fig. 2, Fig. 2 provides the fixedly structural representation of a kind of specific embodiment of capstan head for the utility model.
In a kind of specific embodiment, as shown in Figure 2, the utility model provides a kind of fixedly capstan head that is used for engineering machinery, comprises turntable frame 1, and this turntable frame 1 is connected with the turntable of engineering machinery; Also comprise the supporting rack that is fixed in turntable frame 1 below, supporting rack comprises at least two linking arms 2, and the outer end of each linking arm 2 is hinged with the supporting leg of engineering machinery respectively; Adjacent arbitrarily two linking arms 2 intersect, or the extended line of two adjacent linking arms 2 intersects arbitrarily.
Adopt this structure; 1 revolution of turntable and turntable frame is connected, supporting leg and above-mentioned linking arm 2 is hinged, can realize the revolution of jib and to the supporting role of complete machine; The fixedly capstan head of box-structure in the prior art of comparing; The fixedly turret structure of this structure is simplified greatly, makes that fixedly the consumptive material of capstan head reduces, and heat dispersion strengthens.In addition, when work, the load on the turntable is directly delivered to fixedly capstan head through turntable frame 1, and is delivered to supporting leg through linking arm 2, and the power conducting path is shorter, and the vibrations of generation are less; Meanwhile, the vibrations that the impact that the concrete piston motion produces brings are also less relatively, strengthened the fixedly shock resistance of capstan head.
This shows that the fixedly capstan head of this structure can play the effect that connects turntable, supporting leg equally, and have simple and compact for structurely that shock resistance is strong, thermal diffusivity characteristics preferably.
Need to prove; The above-mentioned specific embodiment does not specifically limit the concrete number and the specific constructive form of linking arm 2; Also limit the fixedly connected mode of capstan head and concrete pump chassis, in fact, every employing linking arm 2 connection supporting legs; Play simplified structure, the fixedly capstan head that strengthens shock resistance and thermal diffusivity is all in the protection domain of the utility model.
The concrete number and the specific constructive form of the linking arm 2 of said fixing capstan head can also further be set.
In a kind of specific embodiment, the number of linking arm 2 is four, and four linking arms 2 intersect X type structure.Adopt this structure, promptly four of engineering machinery supporting legs all adopt above-mentioned linking arm 2 with fixedly capstan head is hinged, make the power conducting path of each supporting leg all shorten, and reduce the fixedly consumptive material of capstan head to greatest extent, strengthen the fixedly heat dispersion of capstan head.In addition, four linking arms 2 intersect and are the intensity that the X type can be strengthened supporting rack, guarantee the supporting rack reliability of structure, strengthen the job stability of supporting rack.
Please refer to Fig. 3 and Fig. 4, Fig. 3 is the structural representation of first integral arms of supporting rack among Fig. 2; Fig. 4 is the structural representation of second integral arms of supporting rack among Fig. 2.
In further scheme, like Fig. 3 and shown in Figure 4, in the X type supporting rack, first integral arms that the linking arm 2 of two positioned opposite is formed in one, second integral arms that the linking arm 2 of two other positioned opposite is formed in one.
