Description

Pipeline lifting device, pipeline transport vehicle and pipeline installation method Technical Field The invention relates to the technical field of auxiliary equipment for installing a tunnel pipeline, in particular to a pipeline lifting device, a pipeline transport vehicle and a pipeline installation method. Background Along with the continuous promotion of underground coal mine mining operation, the auxiliary pipeline laying engineering quantity of the crossheading roadway is large and the operation environment is complex. At present, when a pipeline is installed at the top of a roadway, lifting and positioning are generally carried out manually or by means of simple equipment. When each group of pipelines is installed, after the first pipeline is installed, the bracket is required to be installed, then the subsequent pipelines of the group of pipelines are installed, and when the subsequent pipelines are installed, the pipelines are required to be lifted and penetrate into the installed bracket. The mode is extremely high in labor intensity and low in efficiency, and personnel are located in high-altitude and heavy-object operation environments, so that great potential safety hazards exist. In recent years, although some pipeline grabbing and lifting devices appear, in an attempt to lighten the manual load, the device has obvious limitations that firstly, most of the devices are large in structural size and cannot adapt to narrow and low space conditions of a crossheading roadway, secondly, the mechanical arm type grabbing and lifting device often has insufficient operation space in a densely supported roadway, accurate threading and butt joint of the pipelines are difficult to realize, thirdly, the existing lifting device is concentrated on single pipeline transportation, synchronous lifting of a plurality of pipelines cannot be realized, and the working efficiency is low.
