The invention relates to a lifting appliance anti-swing system for a portal crane. The anti-swing system is arranged on an arm support (10) and is connected with a rotary lifting appliance (9); and the anti-swing system comprises a lifting steel wire rope (1), a lifting sliding frame (2), a constant-tension steel wire rope (3), a lifting mechanism (4), a constant-tension mechanism (5), a head structure (6), a lower structure (7) and a tensioning pulley (11), wherein the lifting mechanism (4) and the constant-tension mechanism (5) are installed on the lower structure (7) and fixed to the root of the arm support (10), and the tensioning pulley (11) is installed on the head structure (6) and fixed to the head of the arm support (10). Compared with the prior art, two sets of steel wire rope devices, namely the lifting steel wire rope and the constant-tension steel wire rope, are creatively adopted, the constant-tension steel wire rope can ascend and descend at any position within the length range of the arm support along with the lifting appliance, so that the rotary motion of the lifting appliance can be realized, and accurate positioning of cargos can be ensured.

    本发明涉及一种用于门机的吊具防摇系统,该防摇系统安装在臂架(10)上,并连接回转吊具(9),所述的防摇系统包括升降钢丝绳(1)、升降滑架(2)、恒张力钢丝绳(3)、升降机构(4)、恒张力机构(5)、头部结构(6)、下部结构(7)及张紧滑轮(11),其中升降机构(4)及恒张力机构(5)安装于下部结构(7)并固定在臂架(10)的根部,张紧滑轮(11)安装于头部结构(6)并固定在臂架(10)头部。与现有技术相比,本发明创造性地采用了两套钢丝绳装置,升降钢丝绳及恒张力钢丝绳。恒张力钢丝绳可跟随吊具实现在臂架长度范围内任意位置的升降,使吊具的回转运动可以实现,并可保证货物的准确定位。
