Device and method for preventing rocker arm from automatically folding and double-rocker arm floor derrick device
The invention discloses a rocker arm self-folding prevention device and method and a double-rocker arm floor derrick device. The rocker arm self-folding prevention device comprises a mounting part, a loading part and a transmission part. The mounting part comprises a guide rail base, and the guide rail base is mounted on a mast of the double-rocker arm floor derrick device; the transmission part comprises a pair of guide rails symmetrically connected to a guide rail base, rolling bearings capable of rolling along the guide rails are arranged in guide grooves of the guide rails, the transmission part further comprises a movable sliding block, and the inner side of the movable sliding block is connected with a bearing rod between the rolling bearings. The loading portion includes at least one resilient assembly connected between the guide rail base and the mobile slide. The rocker arm self-folding prevention device can be applied to the power transmission line tower construction process, the rocker arm folding prevention and self-locking effects are achieved in the rocker arm lifting process, and a derrick device is protected against overturning.
本发明公开了一种防摇臂自收拢装置及方法、双摇臂落地抱杆装置，防摇臂自收拢装置包括安装部分、加载部分和传动部分；所述安装部分包括导轨基座，所述导轨基座安装在双摇臂落地抱杆装置的桅杆上；所述传动部分包括对称连接在导轨基座上的一对导轨，所述导轨的导向槽中设置有能够沿导轨滚动的滚动轴承，还包括移动滑动，所述移动滑块的内侧与滚动轴承之间的轴承杆连接；所述加载部分包括连接在导轨基座和移动滑动之间的至少一个弹性组合件。本发明的防摇臂自收拢装置能够应用于输电线路组塔施工过程，在摇臂的起吊过程中起到防摇臂收拢自锁的作用，保护抱杆装置不发生倾覆。
