Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments.It should be understood that this place is retouched
The specific embodiment stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
In the present invention, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower, left and right, top, bottom " is logical
It refers to referring to orientation shown in the drawings.
First aspect present invention provides a kind of auxiliary of crane, and the auxiliary 10 includes sequentially connected first connection frame
11, it uses one end away from first standard knot 12 of the first standard knot 12 and the second connection frame 13, first connection frame 11
It is connect in the principal arm 20 with crane, first standard knot 12 is to be rotatably connected with second connection frame 13, the pair
Arm 10 further includes for driving second connection frame 13 to become relative to first standard knot 12 and first connection frame 11
The jib lubbing mechanism of width.
The present invention improves traditional auxiliary by using above-mentioned technical proposal, and the first standard knot 12 is set to
Between first connection frame 11 and the second connection frame 13, the depth of section of the first standard knot 12 by 11 tail portion of the first connection frame height
It determines, since the depth of section of the auxiliary reduces along from the direction of first the 11 to the second connection frame of connection frame 13, first
The depth of section of standard knot 12 can be higher than the second connection frame 13, and compared with traditional auxiliary, stress is more preferable, stability is higher, rises
Weight is bigger, and lifting performance is more excellent；Meanwhile first standard knot 12 will not with the second connection frame 13 together varied angle, with tradition
Auxiliary is compared, and lifting height is higher, lifting amplitude range is bigger.
In the present invention, the jib lubbing mechanism can use various structures appropriate, as long as the second connection frame 13 can be driven
Rotation, make to be formed between the second connection frame 13 and the first standard knot 12 different variable phase angle (i.e. the axial direction of the first standard knot 12 with
Angle between the axial direction of second connection frame 13), such as the jib lubbing mechanism may include being articulated with the second connection frame 13
With the telescopic oil cylinder between the first standard knot 12.Specifically, a kind of embodiment according to the present invention, as depicted in figs. 1 and 2,
The jib lubbing mechanism may include that both ends are hingedly connected to first standard knot 12 and the length of second connection frame 13 is adjustable
Varied angle connecting plate 14.That is, the second connection frame 13 can be realized by the length for adjusting varied angle connecting plate 14
Luffing.And in order to realize varied angle connecting plate 14 length adjusting, a kind of embodiment according to the present invention, as shown in figure 3,
The varied angle connecting plate 14 includes the first connecting plate 141 and the second connecting plate 142 being connected, and is opened on the first connecting plate 141
Equipped with the fluting 143 extended along its length, the second connecting plate 142 includes being arranged in parallel and at interval doubling plate, and first connects
Fishplate bar 141 is folded between the doubling plate, be penetratingly provided on the doubling plate be intervally arranged along its length it is multiple
Bolt 144, bolt 144 pass through fluting 143.
In the present invention, first connection frame 11 can be the variable cross-section truss that section is quadrangle, and specific structure can join
See Fig. 1 or Fig. 2.In actual fabrication, since the first standard knot 12 is usually rectangular truss, in order to realize the first connection frame
11 are reliably connected with the first standard knot 12, as depicted in figs. 1 and 2, first connection frame 11 close to first standard
One end of section 12 can have the vertical frame 111 being cooperatively connected with first standard knot 12.Meanwhile in order to realize that varied angle connects
One end close to first standard knot 12 of the installation of fishplate bar 14, second connection frame 13 can have tilt frame 132, institute
The bottom end for stating tilt frame 132 and the bottom end of first standard knot 12 are hinged, the both ends difference of the varied angle connecting plate 14
It is articulated with the top of first standard knot 12 and the top of the tilt frame 132.
When in use, referring to Fig. 1 or Fig. 2, when needing to increase the change angle of the second connection frame 13, it can use lower be located at most
One bolt 144 of right end at this time since the first connecting plate 141 loses the backstop of the bolt 144, and moves to the left, until
143 backstops of slotting are in next bolt 144, so that varied angle connecting plate 14 is maintained at longer length, since varied angle connects
Plate 14 and the first standard knot 12 and the second connection frame 13 are hinged relationship, and at the same time, the second connection frame 13 can be along clockwise
Direction rotation, to realize luffing.When the change angle for needing to continue to increase the second connection frame 13, then it can remove and slot
The bolt 144 of 143 backstops.When needing to reduce the change angle of the second connection frame 13, the second connection frame 13 can be made along counterclockwise
Direction rotation, varied angle connecting plate 14 shorten, and the bolt 144 of extraction is inserted fixation again.
In the present invention, one end away from first standard knot 12 of second connection frame 13 may be provided with first pulley
Group 131.In addition, meeting the demand of different operation amplitude ranges, the auxiliary 10 can in order in the case where guaranteeing lifting capacity
