Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation in the utility model specific embodiment under boom system rounding state.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As the structural representation that Fig. 1 is in the utility model specific embodiment under boom system rounding state, the utility model specific embodiment provides a kind of boom system, comprise jib and drive unit (not shown), wherein, jib comprises five joint arms, be respectively first segment arm 1 hinged successively, second section arm 2, section three, arm 3, section four, arm 4 and Section of five arm 5, drive unit comprises four oil cylinders and linkage, for driving arbitrary joint arm relative to the joint arm rotation be adjacent, often be provided with an above-mentioned oil cylinder and linkage between adjacent two joint arms, particularly, one end and the last joint arm of oil cylinder are hinged, it is hinged that the other end saves arm by linkage and rear one.Jib at least exists and launches completely and draw two states in, under jib rounding state, first segment arm 1, second section arm 2, Section of three arm 3 and Section of four arm 4 in the vertical direction stack gradually, and Section of five arm 5 is between Section of three arm 3 and Section of four arm 4, first segment arm 1 can be positioned at the top of the jib under rounding state, also can be positioned at bottom; Preferably, same perpendicular is positioned under five joint arm rounding states.The boom system of this structure, make jib more compact under rounding state, when do not affect concrete mixer by property, can make full use of joint arm and joint arm between space, make arrange in effective space and more save arm, increase jib cloth scope and flexibility.
It should be noted that, above-mentioned " first ", " second ", " the 3rd ", " the 4th ", " the 5th " refer to the order that each joint arm connects.
In above-described embodiment, the folding mode of jib is: first segment arm 1 and second section arm 2 just roll over that (what is called is just rolled over: adjacent two save jib in a folded configuration, jib base plate is relative with base plate), second section arm 2 and Section of three arm 3 reflexed (so-called reflexed: adjacent two jibs in a folded configuration, jib top board is relative with top board), section three, arm 3 and Section of four arm 4 are just rolled over, section four, arm 4 and Section of five arm 5 are just rolled over, section five, arm 5 is placed between Section of three arm 3 and Section of four arm 4, the space between joint arm and joint arm can be made full use of like this, make arrange in effective space and more save arm.
In further technical scheme, be one of at least bending joint arm in first segment arm 1, second section arm 2, Section of three arm 3, Section of four arm 4 and Section of five arm 5, effectively can avoid the interference of other parts like this; In addition, in order to improve the flexibility under jib deployed condition, two the detail arms be hinged can also one of be at least designed in second section arm 2, Section of three arm 3, Section of four arm 4 and Section of five arm 5, it should be noted that, detail arm is two parts of same joint jib, when jib is in rounding state, the detail arm of same jib is in same straight line or same level.
The utility model specific embodiment additionally provides a kind of concrete mixer, comprise chassis and be arranged on any one boom system above-mentioned on chassis, particularly, concrete mixer also comprises the turntable be arranged on chassis, boom system is hinged on turntable top, under jib rounding state, first segment arm 1, second section arm 2, section three, arm 3 and Section of four arm 4 stacking from top to bottom, section five, arm 5 is between Section of three arm 3 and Section of four arm 4, in addition, boom system can also be hinged on turntable bottom, under jib rounding state, first segment arm 1, second section arm 2, section three, arm 3 and Section of four arm 4 stacking from bottom to up, section five, arm 5 is between Section of three arm 3 and Section of four arm 4.Because this concrete mixer is provided with above-mentioned boom system, when do not affect concrete mixer by property, the space between joint arm and joint arm can be made full use of, make arrange in effective space and more save arm, increase jib cloth scope and flexibility.
