The specific embodiment
Core of the present utility model provides a kind of turntable boom system, the structure design of this system can reduce effectively car load length and after stretch, thereby make compact conformation, and increased traveling security.In addition, another core of the utility model is for providing a kind of engineering machinery that comprises above-mentioned turntable boom system.
In order to make those skilled in the art understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2, Fig. 2 is the structural representation of a kind of embodiment intermediate station of the utility model boom system.
In one embodiment, as shown in Figure 2, turntable boom system provided by the utility model, be used for engineering machinery, particularly, this project machinery can be concrete mixer, and this turntable boom system comprises turntable 1, boom device 2 (being shown among Fig. 3 and Fig. 4) and pivoting support 3; Boom device 2 comprises first segment jib 21, and first segment jib 21 is hinged with the top ends of turntable 1; Pivoting support 3 is connected with the bottom of turntable 1; The top ends of definition turntable 1 and the pin joint of first segment jib 21 are benchmark pin joint 4.
As shown in Figure 2, on the basis of above-mentioned prior art, the top ends of turntable 1 is extended to the direction of the driver's cabin 5 of close described engineering machinery, distance between the centre of gyration 6 of benchmark pin joint 4 and turntable 1 is greater than the radius of pivoting support 3, that is benchmark pin joint 4 is positioned at outside the cylindrical end face of pivoting support 3, and is in a side of driver's cabin 5 directions.
Benchmark pin joint 4 is positioned at outside the cylindrical end face of pivoting support 3 in the utility model, thereby with respect to prior art, the utility model further moves forward boom device integral body to the direction near driver's cabin 5, owing to broken through the restriction of pivoting support 3 cylindrical end faces, thereby the distance of reach can obtain bigger increase, obviously this kind structure design can significantly reduce car load length and after stretch, make structure compact more, and increased traveling security.In other words, do not increase car load length and after under the prerequisite of stretching, pump truck can adopt longer boom device.
Please refer to Fig. 3 and Fig. 4, Fig. 3 is the structural representation of the concrete mixer when comprising the turntable boom system shown in Fig. 2 and being in driving states; Fig. 4 is the structural representation that comprises turntable boom system shown in Fig. 2 and the concrete mixer when in running order.
As shown in Figure 3, for further reduce car load length and after stretch, and make full use of the idle space of driver's cabin 5 tops, benchmark interface point 4 can be further to the direction reach near driver's cabin 5, and is positioned at the top of driver's cabin 5.
As shown in Figure 3, benchmark pin joint 4 be positioned at driver's cabin 5 above the basis on, can also make following improvement: boom device 2 comprises hinged successively more piece jib, be positioned at a plurality of pin joints of pivoting support 3 the same sides when folding in this more piece jib with benchmark pin joint 4, have distance between a pin joint and the centre of gyration 6 at least greater than the distance between the benchmark pin joint 4 and the centre of gyration 6.Obviously, this kind structure design can further reduce car load length and after stretch.
As shown in Figure 3, distance between the definition and the centre of gyration 6 is first pin joint 7 greater than the pin joint of the distance between the benchmark pin joint 4 and the centre of gyration 6, and when jib was folding, the distance between the outer face of first pin joint 7 and the benchmark pin joint 4 was less than the distance between the end face of institute's benchmark pin joint 4 and driver's cabin 5.
As shown in Figure 4, when the first segment jib 21 of boom device 2 when benchmark pin joint 4 rotates in advance and vertically be provided with, because the outer face of first pin joint 7 and the distance between the benchmark pin joint 4 be less than the distance between the end face of benchmark pin joint 4 and driver's cabin 5, thereby the outer face of first pin joint 7 does not interfere with the end face of driver's cabin 5.Obviously, this kind structure design can be so that the jib that respectively saves of boom device 2 launches successively, and jib can not interfere with parts such as driver's cabins 5, need not launch first pin joint, 7 related jibs earlier.
Simultaneously, need to adjust the height standard up to specification of car load, make it be unlikely to superelevation.
On the basis of the foregoing description, can also make further improvement.Such as further reach of, benchmark pin joint 4, thereby excess drive chamber 5 is positioned at the preceding oblique upper of driver's cabin 5.Particularly, the distance between the benchmark pin joint 4 and the centre of gyration 6 is greater than the front end face of driver's cabin 5 and the distance between the centre of gyration 6.Obviously, this kind structure design can further reduce car load length and after stretch.On this basis, because the distance between first pin joint 7 and the centre of gyration 6 is greater than the distance between the benchmark pin joint 4 and the centre of gyration 6, thereby first pin joint 7 also surpassed driver's cabin 5, is positioned at the preceding oblique upper of driver's cabin 5.
In the preceding paragraph technical scheme, this moment is when launching when first segment jib 21, first pin joint 7 is positioned at the place ahead of driver's cabin 5, thereby no matter the outer face of first pin joint 7 and the distance between the benchmark pin joint 4 be greater than or less than the distance between the end face of benchmark pin joint 4 and driver's cabin 5, first pin joint 7 can not interfere with driver's cabin 5, thereby in both cases, jib can launch successively.Certainly, preferably the distance between the outer face of first pin joint 7 and the benchmark pin joint 4 less than the distance between the end face of benchmark pin joint 4 and driver's cabin 5.
In the above-described embodiments, because the different jib quantity differences that boom device comprised, its structure design of boom device of jib that perhaps includes equal number is also different, thereby the position of above-mentioned first pin joint and uncertain, certainly, we can specifically be provided with several positions.Such as, pin joint between joint jib last and the joint jib second from the bottom is first pin joint 7, pin joint between joint jib perhaps second from the bottom and the joint jib third from the bottom is first pin joint 7, and perhaps the pin joint between other adjacent jibs is first pin joint 7.
In above-mentioned any embodiment, can also be to the shaped design of turntable 1, particularly, this turntable 1 can be arcuate structure.
In addition, the utility model also provides a kind of engineering machinery, and as shown in Figure 3 and Figure 4, this project machinery comprises chassis 8 and the fixedly capstan head 9 that is supported by chassis 8; This project machinery also comprises the turntable boom system among above-mentioned any embodiment, and the turntable 1 of this turntable boom system is supported in fixedly on the capstan head 9 by pivoting support 3.Other parts of described engineering machinery can be with reference to prior art, and this paper no longer launches.Particularly, this project machinery can be concrete mixer.
More than engineering machinery provided by the utility model and turntable boom system thereof are described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
