Embodiment Construction
[0017] Such as figure 1 , figure 2 As shown, the present invention is provided with: a riser device, and this riser device comprises: several wheels 1, the structural frame 2 that is installed on the wheel 1, wherein, structural frame 2 is the box-type structure that does not have top surface, and structural frame 2. The support structure 3 for supporting the pipeline 5 is oppositely provided on the vertical plates on both sides, and the support structure 3 is provided with a groove for placing the temporary support 6.
[0018] Concrete operation steps of the present invention are as follows:
[0019] Step 1: Temporarily install one end of the pipeline 5 (the low end behind the riser) to the temporary support 6 of the pipeline 5 by welding, and support it on the riser device;
[0020] Step 2: install the other end of the pipeline (the high point end behind the riser) to the temporary lifting point of the pipeline 5 by welding, and the lifting point is connected with the hoo...

The invention discloses a large-diameter pipeline erecting device and method. The large-diameter pipeline erecting device is provided with a pipeline erecting device body. The pipeline erecting device body comprises a plurality of wheels and a structure frame arranged on the wheels. The structure frame is of a box type structure without a top face. Supporting structures used for supporting a pipeline are oppositely arranged on vertical plates on the two sides of the structure frame. In the pipeline erecting process, the large-diameter pipeline erecting work can be finished only by using one crane, and the problems that due to usage of two cranes, the operation risk is large, and the operation efficiency is low are solved; and meanwhile, the pipe erecting work safety, stability, sealing performance and efficiency are greatly improved.
Description
technical field [0001] The invention relates to pipelines, in particular to a large-diameter pipeline standpipe device and method. It belongs to the field of petroleum and chemical industry. Background technique [0002] In the petrochemical industry, according to the process requirements, it is often necessary to install horizontally placed pipelines upright, that is: the riser work of the pipeline. When it comes to large-diameter pipe risers, due to the large diameter and heavy weight of the pipe, the work of the riser is more complicated, and it is easy to cause damage to the pipe end. [0003] At present, there are two existing methods for realizing the riser of the pipeline. Among them, method one: use two cranes (or other hoisting equipment) to hoist the two ends of the pipeline separately, and hoist the large-diameter pipeline from the ground at the same time together with the cranes. Finally, under the cooperative operation in the air, the riser of the pipeline is ...
