Description
Technical field
The present invention relates to fork truck technical field, be specifically related to fork truck rotary suspension arm.
Background technology
The arm that existing fork truck uses as application number for the mechanical rotary suspension arm as described in the patent application of 20122070945.6 can only spend rotation scope at (0-180), its alerting ability rotated has much room for improvement, and the rotary suspension arm described in this patent application is under rotating for a long time, the precision of rotation can be reduced because of mechanical friction, affect service life.In addition, the technical scheme that this patent application is recorded can only realize arm and move up and down at vertical direction, and can not realize the swing of horizontal direction.
Summary of the invention
The arm anglec of rotation that the present invention is directed to prior art is narrow, cause under long rotation that rotation precision is poor, service life is low and lack the problem of oscillating function, provide and can realize 360 degree and rotate freely, benefit from life-span long and swingable fork truck rotary suspension arm.
The present invention adopts following technological means to solve the problems of the technologies described above: fork truck rotary suspension arm, comprises fixed mount, swing span, swivel mount and oscillating oil cylinder; The front hinge of the first bearing pin and described fixed mount is passed through in one end of described swing span, and the other end of described swing span by turn axle and described swivel mount hinge, and ensures that described swivel mount is positioned at the below of described swing span; One end of described oscillating oil cylinder is arranged on by the second bearing pin on the front of described fixed mount, and the other end of described oscillating oil cylinder is arranged on described swing span by the 3rd bearing pin.
Preferably: described swivel mount also comprises rolling bearing, described rolling bearing is set on described turn axle.
Preferably: described swing span also comprises pendulum bearing, described pendulum bearing is set on described turn axle.
Preferably: the two ends up and down at the described fixed mount back side are respectively arranged with hook, lower draw-bar.
Preferably: the upper end at the described fixed mount back side on described upper welding hook, described lower draw-bar is arranged on the lower end at the described fixed mount back side by bolt.
Preferably: the anglec of rotation of the relatively described swing span of described swivel mount is 360 degree.
Preferably: described swing span is L-type, comprise horizontal ends and vertically hold, between described horizontal ends and described vertical end, being also provided with gusset.
The invention has the advantages that: swing span of the present invention can relatively swing by fixed mount under the effect of oscillating oil cylinder, is convenient to better arrangement of goods.Swivel mount can rotate freely by 360 degree, opposing oscillatory frame, is convenient to hang picking thing.By arranging rolling bearing on swivel mount, reducing mechanical friction, improving service precision and service life.Further, swing span arranges pendulum bearing, can realize floating, between the horizontal ends and vertical end of fixed mount, gusset is set, the phenomenon that when alleviating stressed, stress is concentrated.

Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As described in Fig. 1-4, the open fork truck rotary suspension arm of the present embodiment, comprises fixed mount 1, swing span 2, swivel mount 3 and oscillating oil cylinder 4.
Described fixed mount 1 is existing installation.One end of described swing span 2 is by the front hinge of the first bearing pin 5 with described fixed mount 1, and the other end of described swing span 2 by turn axle 6 and described swivel mount 3 hinge, and ensures that described swivel mount 3 is positioned at the below of described swing span 2.One end of described oscillating oil cylinder 4 is arranged on by the second bearing pin 7 on the front of described fixed mount 1, and the other end of described oscillating oil cylinder 4 is arranged on described swing span 2 by the 3rd bearing pin 8.Described swivel mount 3 comprises through type lubrication adapter 31 and four cantilevers, 32, four cantilevers 32 all angularly distribute for axle center with through type lubrication adapter 31.One end of each root cantilever 32 is all welded on through type lubrication adapter 31, and the other end of each root cantilever 32 all stretches out.
Described swivel mount 3 also comprises rolling bearing 10, and described swing span 2 also comprises pendulum bearing 9, and rolling bearing 10 is positioned at the below of pendulum bearing 9.Described rolling bearing 10 and described pendulum bearing 9 are all set on described turn axle 6,
The two ends up and down at described fixed mount 1 back side are respectively arranged with hook 11, lower draw-bar 12.
Described upper hook 11 welds the upper end at upper described fixed mount 1 back side, and described lower draw-bar 12 is arranged on the lower end at described fixed mount 1 back side by bolt.
The anglec of rotation of the relatively described swing span 2 of described swivel mount 3 is 360 degree.
Described swing span is L-type, comprises horizontal ends and vertically holds, between described horizontal ends and described vertical end, be also provided with gusset 14.
By steel rope being arranged on the cantilever 32 of the present embodiment, goods being hung and gets.By the rotation of the through type lubrication adapter 31 of the present embodiment, drive the rotation of cantilever 32, realize cantilever 32 opposing oscillatory frame 2 and carry out 360 degree rotating freely, improve the efficiency of hanging picking thing.The swing span 2 of the present embodiment can relatively swing by fixed mount 1 under the effect of oscillating oil cylinder, is convenient to better arrangement of goods.By arranging rolling bearing 10 on swivel mount 3, reducing mechanical friction, improving service precision and service life.Swing span arranges pendulum bearing 9, swing span 2 floating at vertical direction or direction of tilt can be realized, can realize hanging the regulation and control of getting angle.Between the horizontal ends and vertical end of fixed mount 1, arrange gusset 14, the phenomenon that when alleviating stressed, stress is concentrated, prevents arm from rupturing.In addition, because the present embodiment has many cantilevers 32, improve stability and the fastness of hanging picking thing further.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; the any amendment done within all spirit in the invention and principle, equivalently to replace and improvement etc., within the protection domain that all should be included in the invention.
