Detailed description of the invention
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Hereafter convenient in order to describe, hereinafter alleged "left", "right" is consistent with the left and right direction of accompanying drawing itself.
As Figure 1-5, container lorry provided by the present invention two luffing combination jib swinging gear comprises pedestal 1, jib 2, left amplitude oil cylinder 3 and right amplitude oil cylinder 4.Wherein: left side and the relevant position, right side of pedestal 1 are respectively arranged with hinge hole, one end of left amplitude oil cylinder 3 is connected in the hinge hole on the left of pedestal 1 by the first bearing pin 31, first bolt 32 and the first packing ring 33, meanwhile, one end of right amplitude oil cylinder 4 is connected in the hinge hole on the right side of pedestal 1 by the second bearing pin 41, second bolt 42 and the second packing ring 43.The middle part of pedestal 1 is provided with hinge hole, and the first end M of jib 2 is also connected in the hinge hole in the middle part of pedestal 1 by the 3rd bearing pin 21, the 3rd bolt 22 and the 3rd packing ring 23.
On the left of second end N of jib 2 and relevant position, right side is provided with hinge hole, in hinge hole on the left of the other end of left amplitude oil cylinder 3 is connected to jib 2 the second end N by the 4th bearing pin 34, the 4th bolt 35 and the 4th packing ring 36, meanwhile, the other end of right amplitude oil cylinder 4 be connected to jib 2 by the 5th bearing pin 44, the 5th bolt 45 and the 5th packing ring 46 the second end N on the right side of hinge hole in.Left amplitude oil cylinder 3 and right amplitude oil cylinder 4 make jib 2 can to the left or right side luffing.
This shows, container lorry provided by the present invention two luffing combination jib swinging gear defines hyperstatic structure, delicate structure, has high stablizing effect.The present invention compared to the prior art, the two luffing combination jib swinging gear of container lorry provided by the present invention reasonable installation on pedestal 1, delicate structure, occupy little space and there is high stablizing effect, the process swinging to the opposite side of transport trolley from the side luffing of container lorry can be realized very easily and fast.Cost is low, simple to operate, easy to maintenance, swings efficiency high.
View when what Fig. 1 showed is container lorry two luffing combination jib swinging gear gathering, as can be seen from Figure 1, when jib 2 mediates, left amplitude oil cylinder 3 is symmetrical with right amplitude oil cylinder 4.That is, length between the hinge hole at left amplitude oil cylinder 3 two ends, equal with the length between the hinge hole at right amplitude oil cylinder 4 two ends, further, the angle between the axial line of the angle between the axial line of left amplitude oil cylinder 3 and the axial line of jib 2 and right amplitude oil cylinder 4 and the axial line of jib 2 is also equal.
View when what Fig. 2 showed is container lorry two luffing combination jib swinging gear operation.First, as can be seen from the figure, pinned connection, cylinder body and pedestal 1 pinned connection on the left of the piston rod of left amplitude oil cylinder 3 and the second end of jib 2.Pinned connection, cylinder body and pedestal 1 pinned connection on the right side of the piston rod of right amplitude oil cylinder 4 and the second end of jib 2.Jib 2, under the telescopic drive of left amplitude oil cylinder 3 and right amplitude oil cylinder 4, realizes the left and right luffing of jib 2 round the middle hinge of pedestal 1.
To the left during luffing, the piston rod of left amplitude oil cylinder 3 is regained, the piston rod of right amplitude oil cylinder 4 stretches out simultaneously, now left amplitude oil cylinder 3 produces the lateral force left application force of AB direction (in the Fig. 5) in the position that it is connected with jib 2 second end N, and right amplitude oil cylinder 4 produces the lateral thrust left application force of AB direction (in the Fig. 5) in the position that it is connected with jib 2, thus, the second end N of jib 2 is swung to the left.
To the right during luffing, the piston rod of right amplitude oil cylinder 4 is regained, the piston rod of left amplitude oil cylinder 3 stretches out simultaneously, now right amplitude oil cylinder 4 produces the lateral force to the right application force of BA direction (in the Fig. 5) in the position that it is connected with jib 2 second end N, and left amplitude oil cylinder 3 produces the lateral thrust to the right application force of BA direction (in the Fig. 5) in the position that it is connected with jib 2, thus, the second end N of jib 2 is swung to the right.
Due to hinge connection and reasonable arrangement of the present invention, left amplitude oil cylinder 3 and right amplitude oil cylinder 4 can make jib 2 carry out operation at the left and right sides symmetrical region of container lorry.Under the control of the hydraulic efficiency pressure system in the external world, can swinging by single handle, conveniently realize jib 2 and swing at the left and right sides luffing of container lorry, swing ultrahigh in efficiency.
The present invention also provides a kind of hoisting device, comprises the two luffing combination jib swinging gear in the various embodiments described above.The other parts of described hoisting device can, with reference to prior art, no longer be launched to describe herein.Hoisting device not only occupies little space and has high stablizing effect after adopting provided by the present invention pair of luffing combination jib swinging gear, very fast and convenient realization can swing to the process of the opposite side of transport trolley from the side luffing of transport trolley.
The present invention also provides a kind of container lorry, comprises the hoisting device in the various embodiments described above.The other parts of described container lorry can, with reference to prior art, no longer be launched to describe herein.After container lorry adopts hoisting device provided by the present invention, not only occupy little space and there is high stablizing effect, very fast and convenient realization can swing to the process of the opposite side of transport trolley from the side luffing of transport trolley.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request of the present invention protection.
