随着国民经济快速发展,油气管道作为连接资源和市场的纽带得到了长足的发展,国内长输管道工程施工地域也越来越广,施工环境日渐复杂,需要在不同地形地貌条件下进行施工作业。目前山区隧道内施工主要采用铺轨道,用卷扬机牵引小车完成布管、对口等作业的方法,不仅施工工期长,而且还需花费大量的轨道购置费,安装、拆卸费,机械设备台班费等。为了满足管道施工的需要,设计制作了全位置电驱动龙门吊。1全位置电驱动龙门吊的基本组成
With the rapid development of the national economy, oil and gas pipelines have made great strides as a link connecting resources and markets. The construction area of domestic long-distance pipeline projects is also getting wider and wider, and the construction environment is becoming increasingly complicated. Construction work needs to be carried out under different topographic and landform conditions . At present, the construction of tunnels in mountainous areas mainly uses the laying of tracks, and the method of winch-pulling car to complete the pipe-laying and mating operations not only requires a long construction period, but also requires a large amount of orbit purchase costs, installation and disassembly fees, machine equipment shift fees, etc. . In order to meet the needs of pipeline construction, design and manufacture of all-position electric drive gantry crane. 1 full position electric drive gantry crane basic components
