The invention belongs to the field of engineering machinery, and discloses a guide system for a single-cylinder rope row telescopic mechanism, a telescopic arm assembly and a crane, the guide system comprises a cylinder barrel end part guide mechanism arranged at the end part of a cylinder barrel of a telescopic cylinder along the telescopic direction; the cylinder barrel end guiding mechanism comprises an end support, a bearing rotating piece, a first side rotating piece and a second side rotating piece, the bearing rotating piece bears the end support, and the first side rotating piece and the second side rotating piece are symmetrically arranged on the two sides of the end support in the telescopic direction. According to the guiding system, the centering guiding effect on the telescopic cylinder under the load telescopic working condition can be effectively improved, so that the risks of rope skipping of a rope row mechanism, abnormal noise caused by metal friction, abrasion of the inner side wall faces of the arm sections and the like are effectively reduced, and then it is guaranteed that all the arm sections can stretch out and draw back normally.
本发明属于工程机械领域,公开了一种用于单缸绳排伸缩机构的导向系统、伸缩臂总成和起重机,所述导向系统包括用于设置在伸缩缸的缸筒沿伸缩方向的端部的缸筒端部导向机构,缸筒端部导向机构包括端部支架、承托转动件、第一边侧转动件和第二边侧转动件,所述承托转动件承托端部支架,第一边侧转动件和第二边侧转动件对称设置在端部支架沿伸缩方向的两侧。本发明的导向系统能够有效提高在负载伸缩工况下对伸缩缸的对中导向效果,从而有效降低出现绳排机构跳绳、金属摩擦异响和臂节内侧壁面磨损等现象的风险,进而保证各臂节能够正常伸缩。
