Visible, when supporting leg Vertical Cylinders 20 is contained in container cavity 11 by needs, auxiliary cylinder 40 first can be made to drive supporting leg Vertical Cylinders 20 to move down, make overturning oil cylinder 30 drive supporting leg Vertical Cylinders 20 rotary motion, and then supporting leg Vertical Cylinders 20 is driven in container cavity 11.Like this, can prevent supporting leg Vertical Cylinders 20 from interfering in switching process and between supporting leg body 10.
As shown in Figure 10, in order to ensure that overturning oil cylinder 30 can drive supporting leg Vertical Cylinders 20 to change between the first position and the second position, hinge-point between overturning oil cylinder 30 and supporting leg body 10 and between the hinge-point between overturning oil cylinder 30 and supporting leg Vertical Cylinders 20 connection lead be the first line 91, hinge-point between overturning oil cylinder 30 and supporting leg body 10 and the connection lead between the hinge-point between auxiliary cylinder 40 and supporting leg Vertical Cylinders 20 are the angle that the angle between the second line 92, first line 91 and horizontal surface is greater than between the second line 92 and horizontal surface.
In the present embodiment, the bottom of supporting leg body 10 is provided with the first stay bearing plate 61, the cylinder body of supporting leg Vertical Cylinders 20 is provided with the second stay bearing plate 62, and when supporting leg Vertical Cylinders 20 is positioned at primary importance, the first stay bearing plate 61 abuts with the second stay bearing plate 62.
The present embodiment, by arranging the first stay bearing plate 61 and the second stay bearing plate 62, can make supporting leg Vertical Cylinders 20 when primary importance, improves the support effect of supporting leg body 10 pairs of supporting leg Vertical Cylinders 20.
In the present embodiment, when supporting leg Vertical Cylinders 20 is in the second place, supporting leg Vertical Cylinders 20 is contained in container cavity 11 along the bearing of trend of supporting leg body 10.Like this, the space of this leg structure can be saved largely.
In the present embodiment, the end plate 14 of supporting leg body 10 is provided with dodge supporting leg Vertical Cylinders 20 dodge hole.Like this, can more easily this supporting leg Vertical Cylinders 20 be proceeded in container cavity 11.Preferably, this dodges hole is downward opening U-lag.
In the present embodiment, supporting leg body 10 is provided with positioning plate 70, positioning plate 70 is provided with downward opening positioning groove, when supporting leg Vertical Cylinders 20 is in the second place, supporting leg Vertical Cylinders 20 is fastened in positioning groove.Preferably, this positioning groove be opening towards U-lag, the internal face of this positioning groove matches with the outside wall surface of supporting leg Vertical Cylinders 20.Like this, the positioning action to supporting leg Vertical Cylinders 20 can be improved.
The present embodiment additionally provides a kind of hoisting crane, comprises leg structure, and leg structure is above-mentioned leg structure.
When hoisting crane in the present embodiment is in running order, supporting leg Vertical Cylinders 20 is in open configuration; When hoisting crane is in off working state, supporting leg Vertical Cylinders 20 is in folded state, and concrete folding process is as follows:
As shown in Fig. 4 to Figure 10, by the oil circuit conducting of overturning oil cylinder 30, it is made to float arbitrarily under external force.Shrink auxiliary cylinder 40, under the pulling force and the Action of Gravity Field of self of auxiliary cylinder 40, supporting leg Vertical Cylinders 20 entirety moves down, until the lower end in contact in bearing pin 50 and key shape hole.
Now, as shown in Figure 7 and Figure 8, supporting leg Vertical Cylinders 20 is separated with the carrying contact surface of supporting leg body 10, like this, when supporting leg Vertical Cylinders 20 can be avoided to rotate and supporting leg body 10 produce and interfere, namely avoid interfering between the first stay bearing plate 61 and the second stay bearing plate 62.
Then, locked auxiliary cylinder 40, shrinks overturning oil cylinder 30, and then drives supporting leg Vertical Cylinders 20 to rotate around bearing pin 50.Fig. 9 is the structural representation of supporting leg Vertical Cylinders 5 when rotating 45 ° of end positions, notes, now should not produce interference between the first stay bearing plate 61 and the second stay bearing plate 62.
Continue to shrink overturning oil cylinder 30, until the housing of supporting leg Vertical Cylinders 20 contacts with the groove of the circular arc of positioning plate 70, then locked overturning oil cylinder 30, completes the folding process of supporting leg Vertical Cylinders 20.
Complete after folding, as shown in Figure 10, the angle between the first line 91 and horizontal surface is greater than the angle between the second line 92 and horizontal surface, otherwise cannot open supporting leg Vertical Cylinders 20.
Supporting leg Vertical Cylinders 20 completes the leg structure after folding as shown in Figure 10, Figure 11 and Figure 13.Supporting leg Vertical Cylinders 20 open process and folding process is similar, therefore no longer to describe in detail.
The leg structure height dimension of existing hoisting crane is comparatively large, and the space that greatly have impact on car load is arranged and Optimal Structure Designing.
The present embodiment adopts two oil cylinders and relevant supplementary structure to achieve the folding of supporting leg Vertical Cylinders and open, can greatly simplified design, and save the performance of design and manufacture cost, improving product, in hoister in large tonnage products application, effect is more obvious simultaneously.
The gordian technique point of the leg structure in the present embodiment is as follows:
(1) what utilize the key shape hole on auxiliary cylinder 40 and supporting leg body 10 can realize supporting leg Vertical Cylinders 20 moves up and down with spacing, ensures that supporting leg Vertical Cylinders 20 is not interfered with other parts in rotation process simultaneously; Then, utilize overturning oil cylinder 30 to rotate supporting leg Vertical Cylinders 20, thus realize the folding of supporting leg Vertical Cylinders 20 and open.
(2) during mode of operation, the carrying contact surface (between the first stay bearing plate 61 and the second stay bearing plate 62) of supporting leg Vertical Cylinders 20 and supporting leg body 10 is not with bolts, overturning oil cylinder thrust and outrigger reaction is relied on to be fixed, simplify the installing/dismounting process of supporting leg Vertical Cylinders 20, conveniently carry out maintain and replace.
Visible, the leg structure in the present embodiment has the following advantages:
(1) during off working state, height of landing leg direction size is only 40% ~ 50% of traditional structure forms, has greatly saved limited space, simplifies supporting leg, the design of vehicle frame and space and arranges, decreases chassis design constraint, improves vehicle performance.
Such as, for radial pattern leg structure, after adopting the structure in the present embodiment, supporting leg folding leans against the layout that vehicle frame two rear flank can not affect vehicle bridge; For H type supporting leg, can effectively increase car load departure angle.
(2) during mode of operation, the carrying contact surface of supporting leg Vertical Cylinders and supporting leg body is not with bolts, relies on overturning oil cylinder thrust and outrigger reaction to be fixed, thus simplifies the installing/dismounting process of supporting leg Vertical Cylinders, conveniently carry out maintain and replace.
(3) structure is simple, can be formed, saved manufacture and improvement cost by the transformation of existing H type supporting leg.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
