[0002] Plastic-coated steel pipe, also known as plastic-coated pipe, steel-plastic composite pipe, and plastic-coated composite steel pipe, is a steel-plastic composite steel pipe with a steel pipe as the base. A layer of plastic anti-corrosion layer is welded on the inner surface of the steel pipe through spraying, rolling, dipping, and suction processes, or a plastic anti-corrosion layer is welded on the inner and outer surfaces. In the process of processing the plastic-coated steel pipe, it is necessary to unload the plastic-coated steel pipe. When unloading the plastic-coated steel pipe, automatic unloading equipment for plastic-coated steel pipe is required.
[0003] In the prior art, there are the following problems:
[0004] When unloading the existing plastic-coated steel pipes, most of them are carried and unloaded by workers manually, which usually requires a lot of manpower and physical strength. The existing solution is to use automatic unloading equipment to export the plastic-coated steel pipes from the box to achieve automatic unloading. However, the existing automatic unloading equipment is not convenient for buffering the plastic-coated steel pipes when unloading the plastic-coated steel pipes, causing the plastic-coated steel pipes to fall to the ground and hit during unloading, which can easily cause the plastic-coated steel pipes to dent. At the same time, when the plastic-coated steel pipes are introduced into the box for storage, it is not convenient to limit the arrangement of the plastic-coated steel pipes, so that the plastic-coated steel pipes are easily skewed after being introduced into the box, making it inconvenient to export them. It is not convenient to export the plastic-coated steel pipes in the box one by one, and two plastic-coated steel pipes are easily stuck at the outlet. Utility Model Content
