The telescopic suspension arm comprises a first suspension arm section, a second suspension arm section and a third suspension arm section, the second suspension arm section is nested in the first suspension arm section, the third suspension arm section is nested in the second suspension arm section, a first fixing seat is arranged on the first suspension arm section, a first pulley is arranged on the upper portion in the second suspension arm section, and a second fixing seat is arranged on the lower portion in the second suspension arm section. A first fixing pin is arranged at the tail end of the third section of suspension arm, an extension arm steel wire rope is arranged in the suspension arm, one end of the extension arm steel wire rope is fixed on the first fixing seat, the other end of the extension arm steel wire rope is fixed on the first fixing pin, and the extension arm steel wire rope penetrates through the first pulley. According to the telescopic suspension arm provided by the invention, synchronous extension and retraction of multiple sections of suspension arms are realized through combination of the steel wire rope and the pulley, the extension amplitude can be changed under the condition that the lifting height of the lifting steel wire rope is not influenced, the light structure is realized, the fault rate is low, and the construction risk in the construction process of a liquid cargo tank is reduced.

    本发明涉及一种可伸缩的吊臂,包括第一节吊臂、第二节吊臂,第三节吊臂,第二节吊臂嵌套在第一节吊臂内,第三节吊臂嵌套在第二节吊臂内,第一节吊臂上设有第一固定座,第二节吊臂内的上部设有第一滑轮,第三节吊臂的尾端设有第一固定销,吊臂内部设置有伸臂钢丝绳,伸臂钢丝绳的一端固定在第一固定座上,伸臂钢丝绳的另一端固定在第一固定销上,伸臂钢丝绳穿过第一滑轮。本发明提供了一种可伸缩的吊臂,通过钢丝绳与滑轮的组合,实现多节吊臂的同步伸缩,在不影响起升钢丝绳起升高度的情况下,能够改变伸出幅度,实现了结构轻型化,且故障率低,减少了液货舱建设过程中的施工风险。
