Fig. 2 is the rounding state structural representation of the utility model jib structure.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be described in further detail:
See figures.1.and.2, the concrete spreader jib structure comprises at least two sections jibs that are hinged, the election mechanism of upper bracket lifting in vertical plane; Election mechanism between each section jib comprises that one is positioned at two-piece boom phase crank-link mechanism 6 to the inside when jib closes up; The jib assembly comprises that three sections jibs are big arm 3-1 (being the principal arm frame), middle arm 3-2 and forearm 3-3 in the present embodiment, and correspondence is provided with the big arm election 5-1 of mechanism to corresponding jib respectively, middle arm is elected the 5-2 of mechanism, the forearm election 5-3 of mechanism.Make in the cloth scope that whole material distributing machine can 360 ° cloth arbitrarily.
Election mechanism between principal arm frame and the upper bracket and between each section jib is that hydraulic pressure is elected mechanism or pneumatic election mechanism or electronic election mechanism, elects angular range and can be set to 0 °～180 °
In the present embodiment, the preferred hydraulic pressure of the election mechanism between each section jib is elected mechanism, comprises that tail end is articulated in the hydraulic jack of the corresponding positioning end of active jib and the push rod that front end is articulated in the connecting rod tail end, and the push rod movable set is in hydraulic jack; The corresponding setting of crank-link mechanism is connected between big arm, the middle arm and is connected in two groups (6-1,6-2) between middle arm, the forearm; Comprise one have three anchor points crank piece (6-1-1,6-2-1) and have the connecting rod (6-1-2,6-2-2) of two anchor points; Crank piece 6-1 links to each other with push rod front end, active jib, connecting rod tail end respectively, and connecting rod front end and driven jib are hinged.Specifically; The 5-1 of election mechanism that is used to elect big arm 3-1 comprises hydraulic jack 5-1-1 and push rod 5-1-2; The 5-2 of election mechanism that is used for electing arm 3-2 comprises hydraulic jack 5-2-1 and push rod 5-2-2, and the 5-3 of election mechanism that is used to elect forearm 3-3 comprises hydraulic jack 5-3-1 and push rod 5-3-2.To elect the push rod 5-1-2 of mechanism, big arm 3-1, connecting rod 6-1-2 hinged with big arm respectively for crank piece 6-1-1, and the connecting rod 6-1-2 other end and middle arm 3-2 are hinged; To elect push rod 5-2-2, middle arm 3-2, the connecting rod 6-2-2 of mechanism hinged with middle arm respectively for crank piece 6-2-1, and the connecting rod 6-2-2 other end and forearm 3-3 are hinged, and the crank piece is substantially triangular in shape, the summit rounding.
For preventing that crank-link mechanism from exposing false hit takes place, the hinge point between each section jib has and is a pair of perk hangers that tapering outwards shrinks, and it is stacked and be articulated in front end that the perk hangers of two-piece boom is the arch suit.Be the protection crank-link mechanism, crank piece and connecting rod are articulated in the folded zone of a pair of perk hangers on the corresponding jib respectively.Particularly; Big arm 3-1 end has hangers 3-1-1; In the arm end have hangers 3-2-1 (the jib two ends that two ends all link to each other with other jib all are provided with hangers), forearm has hangers 3-3-1, crank piece 6-1-1 and connecting rod 6-1-2 are arranged in the hollow region that big arm hangers 3-1-1 and arm hangers 3-2-1 suit are enclosed; Crank piece 6-2-1 and connecting rod 6-2-2 are arranged in the hollow region that arm hangers 3-2-1 and forearm hangers 3-3-1 suit are enclosed, and effectively protect crank-link mechanism and save the space.
The articulated section has the through hole (3-1-2,3-2-2,3-3-2) that supplies the transmission and concrete transmission pipeline to pass between each section jib; The jib side is provided with the supporting mechanism 4-1 that is used for fixing respective line; The inboard that each section jib draws in opposite directions is provided with hook 3-1-4 and hook ring 3-3-4 combination.
Because the big far-end carrying capacity of jib near-end carrying capacity is little, firm for saving material and packaging structure, each section jib cross sectional dimensions is along the direction of extension linear contraction, and each section jib average cross-section size is successively decreased along direction of extension.Each section jib length is successively decreased along direction of extension.
Though the utility model is through illustrating and describe with reference to preferred embodiment; But those skilled in the art should understand, and can be not limited to the description of present embodiment; In the scope of claims, can make the various variations on form and the details.
