Background
The chemical modular production is an advanced production mode at present, and the main flow of the production method is that a manufacturer carries out pipeline layout design on the whole chemical living line according to the actual field situation of a production place of a client, then the whole production line is divided into a plurality of modules, each module is produced in the manufacturer, and then the modules are transported to the production place of the client for field assembly. The modularized production can improve the production quality of the whole production line by relying on the strong manufacturing capability of manufacturers, and compared with the crude living conditions on the production site of customers, the assembly quality of the production line is better and the assembly efficiency is higher. In chemical pipeline projects, most pipelines are prefabricated into pipe sections in factories and then transported to the field for installation. The process of factory fabricated pipe sections, packaging and shipping will be of great importance. What way to protect the fabricated pipe sections is important in factory prefabrication. The packaging and transportation of the pipe sections also directly affects the quality of the field installation. When an improperly packaged pipe segment arrives at the site, the damage to the pipe segment is severe, which in turn increases the workload on the site. The traditional packaging and transporting method is that pipe sections prefabricated in a factory are wrapped by bubble films and then are placed in a wooden box or a container and are fixed through packing belts, and the pipe sections are directly stacked layer by layer. And finally, transporting the seeds through wooden boxes or containers. This conventional method has the following drawbacks:
1. the pipe sections are directly pressed on the pipe sections, so that the pipe sections are easy to deform during stacking;
2. the shaking in the transportation process can cause the pipe section to collide with the pipe section, and the pipe section is deformed due to extrusion;
3. after the pipe sections are transported to the site, the pipe sections are very difficult to transport out of the container, and because the pipe sections are all placed together, no operation space is provided for workers, the workers often only can step on the pipe sections to transport the pipe sections, and secondary damage is caused to the pipe sections; when the hoisting machine is used for unloading, no gap exists between the pipe sections, the hoisting belt cannot be normally used, the pipe sections are separated by using a hard tool (a crowbar and the like), and then the hoisting belt is bound, so that the surface of the pipe sections can be easily damaged by the hard tool.
