Technical field
The invention belongs to technical field of engineering machinery, specifically, more particularly to a kind of secondary arm.
Background technology
Loading machine by switching different equipment, can into luggage, the multi-states multiple working such as fortune, press from both sides, unload, hang, it is wide
It is general to be applied to the engineering fields such as mine, traffic, harbour and building.Under normal conditions, loading machine lifting is matched by single suspender
Standby or secured adjusted formula telescopic arm is realized.Single suspender is simple and practicable, but because using single-unit formula, elongation is limited,
It may be only available for lifting length or highly without the occasion of too big requirement.Secured adjusted formula telescopic arm structure is shortening feelings
The operating mode that single-unit formula can be replaced to be adapted under condition completely, and under elongation state, more extensive operation can be carried out.But by whole
The influence of machine stability, the hanged nominal load capacity of telescopic arm under elongation state can have certain limitations, and be adjusted by fixed
The limitation of section mode can only lift the material in range more by a small margin every time, if it is desired to increasing lifting range, then need locomotive
It can just be achieved, working efficiency is relatively low.
Invention content
It is an object of the invention to overcome drawbacks described above, a kind of secondary arm is provided, which increase the stability of complete machine, carry
High nominal load capacity, and in the case where not moving vehicle, realization freely adjusts lifting amplitude at any time, substantially increases work
Efficiency.
The secondary arm, including first section of arm, secondary section of arm and oil cylinder, first section of arm front end and time section arm upper articulation, it is first
It cuts and is hinged with oil cylinder between arm and secondary section of arm, oil cylinder side is hinged with first section of arm bottom stage casing, and the oil cylinder other side is cut with secondary in arm
Section is hinged.
Further, the first section of arm includes central sill, and central sill one end and time section arm are hinged, the both sides up and down of the central sill other end
It is respectively equipped with the crossbeam being fixedly connected, crossbeam both ends are respectively equipped with connecting plate;Crossbeam both ends are respectively equipped with support plate, in support plate
Lower both ends are fixedly connected with two crossbeams respectively, and support plate side is fixedly connected with connecting plate;Central sill both sides are respectively fixedly connected with
Curb girder, curb girder are fixedly connected with support plate;Central sill bottom is equipped with auxiliary beam, and auxiliary beam is fixedly connected with the crossbeam of lower part;At the top of central sill
Equipped with reinforcing rib, reinforcing rib is fixedly connected with the crossbeam on top.
Further, described section arm bottom is equipped with suspension hook.
Compared with prior art, the beneficial effects of the invention are as follows:
1, the present invention uses first section of arm and time two-section arm configuration of section arm cooperation, the swing arm pull rod company of first section of arm and loading machine
It connects, play fixed supporting role, secondary section of arm can be adjusted at any time the extending range of lifting, easy to use;
2, the present invention controls time the flexible amplitude for cutting arm by the flexible of oil cylinder, and flexible to operation, extending range is wide,
Lifting amplitude can be freely adjusted at any time without moving vehicle, greatly improved work efficiency;
Span is reduced, complete machine can be greatly increased by shrinking time section arm in the position easily tumbled when 3, using
Stability, securely and reliably;
4, first section of arm is by central sill and beam engagement, and assists curb girder and auxiliary beam, and firm supporting is reliable, and ability to bear is strong.

Fig. 4 is the upward view of the present invention.
In figure, 1, suspension hook;2, secondary section of arm;3, axis pin A;4, oil cylinder;5, axis pin B;6, central sill;7, curb girder;8, auxiliary beam;9, it props up
Fagging;10, crossbeam;11, connecting plate;12, reinforcing rib.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings:
As shown in Figure 1, secondary arm, including first section of arm, secondary section of arm 2 and oil cylinder 4, secondary section of 2 bottom of arm is equipped with suspension hook 1, first
Arm front end and time section 2 upper articulation of arm are cut, oil cylinder 4,4 side of oil cylinder and first section of arm bottom are hinged between first section of arm and secondary section of arm 2
Portion stage casing is hinged, and 4 other side of oil cylinder is hinged by axis pin A3 and time section 2 stage casing of arm.
As shown in Fig. 2, first section of arm includes central sill 6,6 one end of central sill is hinged by axis pin B5 and time section arm 2, and central sill 6 is another
The both sides up and down at end are respectively equipped with the crossbeam 10 being fixedly connected, and 10 both ends of crossbeam are respectively equipped with connecting plate 11;10 both ends of crossbeam point
Not She You support plate 9, support plate 9 play the role of enhancing it is fixed, 9 upper and lower ends of support plate respectively with two crossbeams 10 fix connect
It connects, 9 side of support plate is fixedly connected with connecting plate 11, and connecting plate 11 plays vertical supporting role, while being also used as interface and rear portion
Equipment connects;The curb girder 7 that 6 both sides of central sill are respectively fixedly connected with, curb girder 7 are fixedly connected with support plate 9, and curb girder 7 is propping up
