Description

Technical Field

[0001] The utility model relates to the field of glass fiber reinforced plastic pipeline installation, in particular to a glass fiber reinforced plastic pipeline installation matching construction device. Background Art

[0002] FRP pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. It is made of glass fiber with a resin matrix, which is wound layer by layer on a rotating core mold according to the process requirements, and quartz sand is evenly spread between the fibers at a long distance as a sand layer. Its pipe wall structure is reasonable and advanced, which can give full play to the role of the material. Under the premise of meeting the use strength, the rigidity is improved, ensuring the stability and reliability of the product.

[0003] After searching the patent document with the announcement number CN220727323U, the patent document discloses "a super-large glass fiber reinforced plastic pipe installation and docking construction device. After the glass fiber reinforced plastic pipe is lifted by a large lifting device, the alignment plug shaft on the first alignment platform on the outer wall of the mechanical arm can be aligned and inserted with the alignment plug hole on the second alignment platform on the mechanical arm on the lifted glass fiber reinforced plastic pipe of the next section. In this way, the glass fiber reinforced plastic pipes at both ends can be directly accurately docked, saving time and labor";

[0004] However, the lengths of the FRP pipes required for the joint construction are different, and the length of the crossbeam structure of the above-mentioned device is fixed, which results in that the length of the FRP pipe that can be used for the joint construction by the above-mentioned device is limited. If the length of the FRP pipe to be constructed is long, the above-mentioned device can only clamp one end of the pipe joint to a certain extent. In this way, after the pipe is lifted, due to the weight of the end of the pipe that is not clamped, the FRP pipe will tilt toward the unclamped end, thereby making the joint construction difficult. If the pipe is short, it is not easy to clamp the pipe. Utility Model Content
