The invention relates to the technical field of crane hoisting equipment, and discloses a vertical limiting mechanism for a crane, which comprises a truss, a linear motor is fixedly mounted in the middle of the top end of the truss, and the top end of the linear motor is in transmission connection with a linkage slide rail; a support with the bottom end extending to the bottom of the reel is fixedly installed in the middle of one side of the linkage sliding rail, a fixed shaft rod is movably connected into the communicating groove, and an induction connecting rod penetrating through the interior of the fixed shaft rod is arranged in the communicating groove; the other end of the fixed shaft rod is fixedly provided with an induction connecting rod, and a steel wire rope wound on the outer surface of the reel penetrates through the induction connecting rod. According to the vertical limiting mechanism used in the travelling crane, due to the arrangement of the support and the structure on the support, when the steel wire rope on the reel is tensioned, the travelling crane structure can be automatically adjusted according to the inclination angle of the steel wire rope, and the travelling crane structure is made to move to the position over goods, so that the phenomenon that the travelling crane structure shakes due to inclination of the steel wire rope when the goods are lifted is avoided.
本发明涉及行车吊装设备技术领域,且公开了一种用于行车中的垂直限位机构,包括桁架,所述桁架顶端的中部固定安装有线性电机,所述线性电机的顶端传动连接有联动滑轨,所述联动滑轨一侧的中部固定安装有底端延伸至绞轮底部的支架,所述连通槽的内部活动连接有固定轴杆,所述连通槽的内部设有穿过固定轴杆内部的感应连杆,所述固定轴杆的另一端固定安装有缠绕在绞轮外表面上的钢丝绳穿过其内部的感应连杆。该用于行车中的垂直限位机构,对于支架及其上结构的设置,可在绞轮上的钢丝绳拉紧时,根据其倾斜的角度自动地对调整该行车结构,并使其移动到货物的正上方,使得该行车结构在提升货物时不会因钢丝绳的倾斜而发生晃动的现象。
