Brief description of the drawings
Fig. 1 is the schematic diagram of crane arm support of the present invention；
Fig. 2 is the structural representation of the application example of arm support one shown in Fig. 1.
Embodiment
It is described in detail below in conjunction with accompanying drawing with specific embodiment.Many details are elaborated in the following description
In order to fully understand the present invention.But the invention can be embodied in many other ways as described herein, ability
Field technique personnel can do similar popularization in the case of without prejudice to intension of the present invention, therefore the present invention is not by following public tool
The limitation of body embodiment.
The basic conception of the present invention is can to open up at least one lightening hole in opening area in arm support side wall.Obviously,
To ensure to meet Fatigue life design requirement, the key element such as size, shape and position of opening of lightening hole carries out a definite limitation and excellent
Change, illustrated below in conjunction with the accompanying drawings with specific embodiment.
Fig. 1 is referred to, the figure is the schematic diagram of crane arm support of the present invention.Lightening hole is set on the crane arm support, this
A little lightening holes not can be opened up arbitrarily, otherwise will seriously damage arm support.In fact, lightening hole in the present embodiment is opened up
Mode is by l-G simulation test repeatedly, strict and the result of field test, size, shape and the position of opening of these lightening holes
Organic whole is constituted etc. key element, is thus reached on the basis of Fatigue life design requirement is met and mitigates arm support weight
Purpose, it is described in detail below.
As shown in figure 1, in the arm support 100, relative position that can be between opening area profile 2 and arm support side wall gabarit 1
Relation meets following condition：
Minimum range L1 that can be between opening area left profile and the left outside exterior feature of arm support side wall is maximum for arm support side wall longitudinal direction
The 1/10~1/9 of size L；
Minimum range L2 that can be between opening area right wheel exterior feature and the right gabarit of arm support side wall is arm support side wall longitudinal direction maximum
The 1/10~1/9 of size L；
Minimum range H1 that can be on opening area on profile and arm support side wall between gabarit is laterally maximum for arm support side wall
The 1/4~1/3 of size H；
Minimum range H2 that can be under opening area bottom profiled and arm support side wall between gabarit is laterally maximum for arm support side wall
The 1/4~1/3 of size H.
For the size of lightening hole 3, following condition should be met：
Lightening hole is the 1/4~1/ of arm support side wall horizontal maximum size H in the horizontal full-size D2 of arm support side wall
3；
Full-size D1 of the lightening hole in arm support side wall longitudinal direction is 2~3 times of arm support side wall horizontal maximum size H.
Meanwhile, the sectional area sum of lightening hole 3 be not more than can opening area area 35%~40%.
Due to it is above-mentioned can opening area fatigue life on 5% times of arm support maximum life value, and this can aperture area
The stress in domain is relatively small, influences smaller to arm support fatigue life after perforate, advantageously ensures that the safety of arm support.
Especially, in the case where opening up multiple lightening holes, the interval of lightening hole should also be limited, its adjacent lightening hole
Minimum range d2 between profile is not less than the half apart from d1 at adjacent lightening hole center.
As shown in figure 1, the shape of lightening hole 3 can be a variety of：For example, lightening hole 3 is circular hole, diameter D is not more than arm support side
The 1/4~1/3 of wall horizontal maximum size H；For another example, lightening hole 3 is elliptical aperture, and short axle b is not more than arm support side wall laterally most
The 1/4~1/3 of large scale H, major axis a is not more than 2 times of short axle b, and long axis direction is arm support axial direction；And for example, lightening hole 3 is length
Circular hole, lateral dimension D2 is not more than the 1/4~1/3 of arm support side wall horizontal maximum size, and longitudinal size D1 maximum is horizontal stroke
To 2 times of dimension D 2.
It is noted that set bearing pin and during oil cylinder seat in arm support, also reply can opening area add sternly：If arm support is provided with
Bearing pin, on the basis of aforementioned condition is met, can opening area profile should be close on the inside of bearing pin；If setting oil cylinder seat in the middle part of arm support
When, should make can opening area right wheel it is wide close to oil cylinder seat.
Fig. 2 is referred to, the figure is the structural representation of the application example of arm support one shown in Fig. 1.The arm support 100 is by a top plate
11st, a bottom plate 12 and biside plate 13, constitute box structure；Some reinforcing plates 14, along arm support lateral arrangement, for strengthening arm support
Structural strength；One oil cylinder seat 15, is arranged in the middle part of arm support, for being hinged driving oil cylinder (not shown)；Bearing pin 16, is arranged on arm
The head end A and/or tail end B of frame 100, the rotation for realizing arm support.
, can opening area region S satisfactions for such a box structure：
Can the ultimate range H3 of profile and side plate center line on opening area, can opening area bottom profiled and side plate center line
Ultimate range H4 be respectively the 1/8~1/6 of side plate width H0.
Because setting bearing pin 16, minimum range D3 that can be on the inside of opening area profile and bearing pin is 10cm~20cm.Meanwhile, because
Be provided with reinforcing plate 14 and oil cylinder seat 15, should further such that：Can opening area left profile close to leftmost side reinforcing plate 14, can open
Bore region right wheel is wide close to the left side of oil cylinder seat 15.
The present invention, based on equivalent life design philosophy, is opened up from the most concerned life of product of user on arm support 100
Some lightening holes 3, rather than the reinforcement in intensity is pursued simply；Thus, arm support 100 is realized on the basis of ensureing that the life-span is constant
Structure optimization, improve arm support 100 performance.Specifically：By opening up lightening hole 3, make each position life-span of arm support 100
Reach unanimity, realize the loss of weight of arm support 100, reduce production cost；Meanwhile, increase the flexibility of arm support 100, realize arm support 100
Passive vibration damping, improves the resistance to shock of arm support 100；In addition, can also improve the flexibility of arm support 100, the work of arm support 100 is lifted
Efficiency.
It the above is only the preferred embodiment of the present invention, it is noted that above-mentioned preferred embodiment is not construed as pair
The limitation of the present invention, protection scope of the present invention should be defined by claim limited range.For the art
For those of ordinary skill, without departing from the spirit and scope of the present invention, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as protection scope of the present invention.
