Description

Technical Field

[0001] The utility model relates to the technical field of material discharge of process pipelines of chemical plants, and more specifically, to a combined device for material discharge of pipelines. Background Art

[0002] In the prefabrication of process pipelines for chemical plants, the cutting of pipeline raw materials is an important part of the construction process. Traditional pipeline cutting is done by manual and hoisting machinery assistance. The pipeline material to be cut is placed on sleepers or steel sections, and then cut using a plasma cutter or a pipe cutter. This method has many limitations. Since the length of the pipe section raw materials is generally long and the weight of the pipeline is heavy, a large amount of labor and hoisting machinery are required during the material unloading process. The efficiency of manual unloading is low, and the labor intensity of the unloading workers is high and they are prone to fatigue, which affects the processing efficiency and is prone to safety accidents. In addition, the cutting process requires continuous adjustment of the position of the pipeline or cutting machinery. During the unloading process of heavy pipelines, hoisting machinery is required, which increases the construction risk of the cutting operation. Therefore, the utility model provides a stable and efficient unloading auxiliary device. Utility Model Content
