Floor type double-rocker arm derrick
The invention relates to the technical field of double-rocker-arm derricks, and discloses a floor type double-rocker-arm derrick which comprises tower bodies and an electric control box, the tower bodies are vertically arranged, the adjacent tower bodies are connected through bolts, an upper support is fixedly installed at the top of the outer side of each tower body, and a slewing mechanism is installed at the top of each upper support. A mast is installed on the top of the slewing mechanism, side rocker arms are symmetrically and rotationally installed on the outer side of the slewing mechanism, and lifting hooks are arranged at the bottoms of the tail ends of the side rocker arms. The rotary bearing is driven to rotate through the variable frequency motor, horizontal rotation is more accurate, manual pulling is not needed, and safety is improved; through the jacking mechanism, hydraulic jacking is achieved, and the tower body is rapidly lifted and installed; hoisting and variable-amplitude steel wire rope paths are transformed, and the method is suitable for assembling of the extra-high-voltage steel tube tower; compared with a traditional floor type double-rocker-arm derrick, the whole equipment is easier to install, the construction period is shortened, safety is better, structural strength is higher, and working capacity is higher.
本发明涉及双摇臂抱杆技术领域，公开了一种落地式双摇臂抱杆，包括塔身和电控箱，所述塔身竖直排列，相邻的塔身之间通过螺栓进行连接，所述塔身的外侧顶部固定安装有上支座，所述上支座的顶部安装有回转机构，所述回转机构的顶部安装有桅杆，所述回转机构的外侧对称转动安装有侧摇臂，所述侧摇臂的末端底部设有吊钩。本发明通过变频电机驱动转动回转轴承，水平旋转更加精准，无需人力拉动，提高安全性；通过顶升机构，实现液压顶升，快速对塔身进行升高安装；改造起吊及变幅钢丝绳路径，适合特高压钢管塔的组立；整体设备更易安装，相较于传统的落地式双摇臂抱杆来说，更易安装，节省工期，且安全性更好，结构强度更高，工作能力更强。
