The invention discloses a use method of a high hanging type safety rope device for a crawler crane boom, which comprises the following steps: unfolding an inhaul cable, taking down a pin shaft I on a connecting support I at one end of the boom, enabling a vertical rod I to rotate to a specified position around the pin shaft, and mounting and fixing by using the taken-down pin shaft I after the vertical rod I reaches the specified position; a second pin shaft, connected to a second support, at the other end of the arm support is taken down, and a second vertical rod rotates around the pin shaft to a designated position and is fixed through the taken-down second pin shaft; the height of the first vertical rod or the second vertical rod of the safety rope is adjusted, the pin shaft connecting the core rod and the sleeve rod on the vertical rod is taken down, and the core rod of the first vertical rod extends to a designated position and then is fixed through the two taken-down pin shafts. The length of the inhaul cable can be properly adjusted; the switching mode of the vertical rods on the two sides of the safety rope from the working state to the transportation state is safe, simple and rapid; and the requirements of operation at different heights are met through the telescopic vertical rod.
本发明公开了一种履带起重机臂架用高挂式安全绳装置的使用方法,拉索展开,将臂架一端的连接支座一上的销轴一取下,使立杆一能够绕销轴旋转至指定位置,到达指定位置后利用取下的销轴一进行安装固定;将臂架另一端连接支座二上的销轴二取下,使立杆二绕销轴旋转至指定位置,并利用取下的销轴二进行固定;调节安全绳立杆一或立杆二高度,取下立杆上的连接芯杆和套杆的销轴,将立杆一的芯杆伸长至指定位置后用取下的2个销轴进行固定。本发明拉索长度可进行适当调整;安全绳两侧立杆从工作状态向运输状态转换方式安全、简单、快捷;通过可伸缩立杆满足了不同高度作业需求。
