The invention discloses rotary speed reduction equipment of an engineering tower crane. The rotary speed reduction equipment comprises the tower crane, a winding drum, a first bearing seat, a second bearing seat, a winding drum shaft, a first motor, a speed reducer and a transfer assembly; the tower crane comprises a balance arm frame; the first bearing seat and the second bearing seat are both fixed to the upper surface of the balance arm frame; a connecting line between the first bearing seat and the second bearing seat is perpendicular to the length direction of the balance arm frame; a winding drum is coaxially and fixedly arranged on the winding drum shaft in a sleeving manner; the winding drum is used for winding a traction rope; and one end of the winding drum shaft is rotationallyconnected to the first bearing seat through a bearing, and the other end of the winding drum shaft is rotationally connected to the second bearing seat through a bearing. The probability that a speedreducer shell, an output end bearing and an oil seal are damaged due to composite stress can be greatly reduced, and therefore normal and safe operation of the tower crane is guaranteed.

    本发明公开了一种工程塔机的回转减速设备,包括塔机、卷筒、第一轴承座、第二轴承座、卷筒轴、第一电机、减速机和中转组件;所述塔机包括平衡臂架;所述第一轴承座和所述第二轴承座均固定于所述平衡臂架的上表面;所述第一轴承座和所述第二轴承座之间的连线垂直于所述平衡臂架的长度方向;所述卷筒同轴固定套设于所述卷筒轴;所述卷筒用于绕设牵引绳;所述卷筒轴的一端通过轴承转动连接于所述第一轴承座,所述卷筒轴的另一端通过轴承转动连接于所述第二轴承座;能够大大降低减速机机壳及输出端轴承、油封的因承受复合应力而损坏的几率,从而保证塔机的正常安全运行。
