The method comprises the steps that the variable-amplitude steel wire rope is installed on an arm frame in a factory, the variable-amplitude steel wire rope is guided and locked on a main lifting winding drum through a hoisting tackle and a steel wire rope carrier roller device, all the redundant steel wire rope can be stored in the main lifting winding drum, and after an external field variable-amplitude mechanism is installed, the variable-amplitude steel wire rope is fixed to the main lifting winding drum. And the variable-amplitude steel wire rope is temporarily locked through a rope clamp, the variable-amplitude steel wire rope in the main lifting winding drum is all placed on the ground, straightened out and guided to the variable-amplitude winding drum again through a guide rope, then the variable-amplitude steel wire rope is tightened till temporary locking is not stressed, the safety rope is dismantled, the rope continues to be slowly wound up, finally, the rope clamp and the traction rope are dismantled, and the periphery is manufactured for 6 seconds after acceptance. Large hoisting equipment does not need to be arranged on an external field, the construction cost is saved, the external field construction time is greatly shortened, the external field construction time and personnel investment are saved, the construction difficulty is reduced, the construction period is shortened, and the construction cost is reduced.

    本发明公开了一种固定吊变幅钢丝绳安装方法:在厂内将变幅钢丝绳安装在臂架上,变幅钢丝绳通过起重滑车和钢丝绳托辊装置引导并锁固在主起升卷筒上,多余钢丝绳全部能收纳进主起升卷筒上,等外场变幅机构安装完成后,再通过绳夹临时锁固变幅钢丝绳,将主起升卷筒中的变幅钢丝绳全部放到地面上,理顺,重新用引绳导引到变幅卷筒上,然后收紧变幅钢丝绳,直到临时锁固不受力,拆除安全绳,继续缓慢收绳,最后拆除绳夹和牵引绳,报验收后做好周边6S。本发明不需要外场配备大型起重设备,节省施工成本,外场施工的时间大大降低,节约外场施工时间和人员投入降低施工难度,缩减施工周期和降低施工成本。
