The invention provides a method for interchanging pulleys on a crane tripod, which comprises the following steps of: arranging a sliding suspension cable on a variable-amplitude steel wire rope, fixedly connecting two ends of the sliding suspension cable with the left side and the right side of the top of the tripod respectively after crossing the variable-amplitude steel wire rope, and limiting the sliding suspension cable to move on the variable-amplitude steel wire rope by arranging a bandage; therefore, the chain block arranged on the sliding suspension cable is used for hoisting the pulley to be exchanged for disassembly, and the chain block is pulled through the traction rope, so that the pulley to be exchanged is moved through the sliding suspension cable, and the exchange of the pulleys on the left side and the right side of the top of the tripod is realized.
本发明提供一种起重机三角架上的滑轮互换方法,通过在变幅钢丝绳上设置滑动悬索,使滑动悬索的两端横跨变幅钢丝绳后分别与三角架顶部左右两侧固定连接,通过设置绑带限制滑动悬索在变幅钢丝绳上移动,从而通过设置在滑动悬索上的手拉葫芦吊取待互换的滑轮进行拆卸,并通过牵引绳拉动手拉葫芦,进而将待互换的滑轮通过滑动悬索进行移动,从而实现三角架顶部左右两侧滑轮互换。
