The invention discloses a foldable introducing mechanism. The foldable introducing mechanism comprises an introducing beam I, an introducing beam II and a supporting assembly, wherein the introducingbeam I is fixed below a special joint, one end of the introducing beam I is hinged to one end of the introducing beam II, and the supporting assembly is used for supporting the introducing beam II after the introducing beam II is flatly placed and folded. The supporting assembly comprises a pull rod I and a pull rod II, wherein one end of the pull rod I is fixed to the upper part of the special joint, the other end of the pull rod I is hinged to the introducing beam II, and the pull rod I is used for supporting the introducing beam II when the introducing beam II is flatly placed. One end of the pull rod II is fixed to the upper part of the special joint, the other end of the pull rod II is hinged to the introducing beam II, and the pull rod II is used for supporting the introducing beam II when the introducing beam II is folded. By adopting the structure, the travel of a lifting hook on a crane boom can be increased, and the maximum lifting weight can be increased.
本发明公开了一种可折叠引进机构,包括引进梁I、引进梁II、支撑组件,引进梁I固定在特殊节的下方,其一端与引进梁II的一端铰接,支撑组件用于引进梁II平放与折叠后的支撑。支撑组件包括拉杆I和拉杆II,拉杆I一端固定在特殊节的上部,另一端与引进梁II铰接,用于引进梁II平放时的支撑。拉杆II一端固定在特殊节的上部,另一端与引进梁II铰接,用于引进梁II折叠时的支撑。上述结构可以扩大起重臂上吊钩的行程,增加最大吊重量。
