For this reason, there is now folding conveying arm, as at application number being was to disclose a kind of fortune sand self-unloading oceangoing ship hydraulic pressure two joints in the 2013.6.24 patent documentation that openly day is 2013.9.25 upwards to fold conveying arm 201310250941.6 applyings date, wherein the expansion of this folding conveying arm and folding be to realize by connecting rod mechanism and four-bar mechanism, its less reliable.
Summary of the invention
In order to improve the expansion of folding conveying arm and folding reliability, the utility model provides a kind of fortune sand self-unloading oceangoing ship two joint multimachine structure folding conveying arm.
For achieving the above object, the folding conveying arm of a kind of fortune sand self-unloading oceangoing ship two joint multimachine structure, comprise erecting bed, one-level arm, secondary arm, bar-link drive, one end of one-level arm is articulated on erecting bed, one end of secondary arm is articulated in the other end of one-level arm, and bar-link drive is hinged between erecting bed and one-level arm; Between one-level arm and secondary arm, be hinged with rocker arm body.
Further, described bar-link drive comprises the first oil cylinder, triangle swing arm and connecting rod; The cylinder body of the first oil cylinder is hinged on erecting bed, and the piston rod of the first oil cylinder is hinged on one of them angle of triangle swing arm; Another angle of triangle swing arm is hinged on erecting bed, and the 3rd angle of triangle swing arm is hinged on one end of connecting rod, and the other end of connecting rod is hinged on one-level arm.
Further; rocker arm body comprises rocking arm, the second oil cylinder and the 3rd oil cylinder; one end of rocking arm is hinged between one-level arm and secondary arm; the cylinder body of the second oil cylinder is hinged on one-level arm; the piston rod of the second oil cylinder is hinged on the other end of rocking arm; the cylinder body of the 3rd oil cylinder is hinged on secondary arm, and the piston rod of the 3rd oil cylinder is hinged on the other end of rocking arm.
The beneficial effects of the utility model are: adopt rocker arm body, as will be realized the expansion of secondary arm and folding, secondary arm is had to application force and antagonistic force, like this, can make secondary arm pulsation-free launch and folding, can prevent from launching and folding because of gravity moment of secondary arm.Specifically, when when launching secondary arm, the second oil cylinder has thrust to secondary arm, the 3rd oil cylinder has deboost to secondary arm, like this, even wherein an oil cylinder lost efficacy, also can prevent the moment expansion of secondary arm, thereby improved safety performance, on the contrary, when at folding B grade arm, the second oil cylinder has pulling force to secondary arm, the 3rd oil cylinder has jacking force to secondary arm, thereby has improved the folding safety performance of secondary arm.When adopting triangle swing arm, its good stability, therefore, expansion and the folding property of folding conveying arm are good, the good stability of folding conveying arm.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figures 1 to 5, the folding conveying arm of fortune sand self-unloading oceangoing ship two joint multimachine structure comprises erecting bed 1, one-level arm 2, secondary arm 3, bar-link drive 4 and rocker arm body 5.
Erecting bed 1 is arranged on the fore of fortune sand self-unloading oceangoing ship.One end of one-level arm 2 is articulated on erecting bed 1, and one end of secondary arm 3 is articulated in the other end of one-level arm 2.
Described bar-link drive 4 comprises the first oil cylinder 41, triangle swing arm 42 and connecting rod 43; The cylinder body of the first oil cylinder 41 is hinged on erecting bed 1, and the piston rod of the first oil cylinder 41 is hinged on one of them angle of triangle swing arm 42; Another angle of triangle swing arm 42 is hinged on erecting bed 1, and the 3rd angle of triangle swing arm 42 is hinged on one end of connecting rod 43, and the other end of connecting rod 43 is hinged on one-level arm 2.
Rocker arm body 5 comprises Rocker arm 51, the second oil cylinder 52 and the 3rd oil cylinder 53; one end of Rocker arm 51 is hinged between one-level arm 2 and secondary arm 3; cylinder body of the second oil cylinder 52 is hinged on one-level arm 2; piston rod of the second oil cylinder 52 is hinged on the other end of Rocker arm 51; cylinder body of the 3rd oil cylinder 53 is hinged on secondary arm 3, and the piston rod of the 3rd oil cylinder 53 is hinged on the other end of Rocker arm 51.
