一种塔式起重机变幅小车,包括安装支架和至少一个设置在所述安装支架的安装空间内的滑轮,所述安装支架上设有第一安装轴,所述滑轮安装在所述第一安装轴上,所述滑轮的外周面上设有槽口;沿所述第一安装轴的轴线方向;所述安装支架上还设有阻挡结构,所述阻挡结构包括若干从所述槽口的旁侧延伸以设置在所述安装间隙内的第一阻挡体,所述槽口至少部分伸入设置在两所述第一阻挡体所围成的空间内。通过设置从槽口的旁侧延伸以设置在至安装间隙内的第一阻挡体,阻挡结构能够有效防止安装在槽口内的钢丝绳沿槽口向旁侧脱出,避免钢丝绳移动到安装间隙内而发生窜槽、脱槽、跳绳、卡绳等故障,提高了塔式起重机变幅小车在使用过程中的安全性。

    The invention discloses a tower crane luffing trolley. The tower crane luffing trolley comprises an installation bracket and one or more pulleys arranged in the installation space of the installationbracket, wherein a first installation shaft is arranged on the installation bracket, the pulleys are installed on the first installation shaft, and notches are formed in the peripheral surfaces of thepulleys; in the axis direction of the first installation shaft, an installation gap is formed between the installation frame and the adjacent pulley and/or between the pulleys; and a blocking structure is further arranged on the installation bracket, the blocking structure comprises a plurality of first blocking bodies extending from the sides of the notches to be arranged in the installation gap, and the notches are at least partially arranged in a space enclosed by two first blocking bodies in an extending mode. The first blocking bodies extend from the sides of the notches to be arranged in the installation gap, so that the blocking structure can effectively prevent steel wire ropes installed in the notches from coming out to the side along the notches, the faults of channeling, slotting, rope skipping, rope jamming and the like caused by the steel wire ropes moving into the installation gap are avoided, and the safety of the tower crane luffing trolley in the use process is improved.
