Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic pipe production and processing, in particular to a glass fiber reinforced plastic pipe lining device. Background Art

[0002] Epoxy FRP pipes are primarily composed of glass fiber reinforcement and resin as the main material. The glass fiber provides strength to achieve the required mechanical properties, while the resin, as the main material, facilitates load transfer, provides heat resistance, and provides corrosion protection. Lining the inner wall of the FRP pipe increases the resin content, making the inner wall denser and improving the pipe's anti-seepage and corrosion resistance. Epoxy FRP pipes offer excellent corrosion resistance and a long service life, making them widely used in the petroleum, petrochemical, and offshore shipbuilding industries.

[0003] Epoxy fiberglass pipe lining requires winding a resin-impregnated felt onto a mold, followed by fiberglass wrapping. Currently, the process involves pouring resin glue onto the mold, manually wrapping the felt around the mold, and then manually pouring resin glue onto the felt. This manual process is labor-intensive and cumbersome, and can also lead to issues like felt breakage, uneven wrapping, and uneven impregnation, impacting product quality. Utility Model Content

[0004] In view of the above shortcomings of the existing technology, the purpose of the present invention is to provide a fiberglass reinforced plastic pipe lining device that can solve the problem that the existing lining method is labor-intensive and easily leads to substandard product quality.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A fiberglass reinforced plastic pipe lining device includes a frame, on which a cylinder, a roller and a glue groove are arranged in sequence from left to right; a hair roller is provided on the piston rod of the cylinder, a lining felt roll is sleeved on the roller, the glue groove is connected to the frame via a connecting rod, and multiple rows of staggered leakage holes are provided at the bottom of the glue groove; and a mold is also included, which is located below the glue groove.

[0007] Preferably, the connecting rod is connected to the vehicle frame via bolts.

[0008] Preferably, the cross section of the glue groove is an inverted trapezoidal structure.

[0009] Preferably, one end of the drum is rotatably connected to the frame, and the other end is provided with a nut, and the nut is threadedly connected to the drum.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: by installing the lining making device of the present invention on a winding trolley, the movement of the winding trolley drives the movement of the device, and the glue in the glue tank is driven by the winding trolley to drip evenly onto the mold, thereby realizing the winding of the lining felt onto the mold, improving the quality of the product and reducing labor intensity.

[0015] The following describes the invention of the present invention in detail by way of examples in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Example

[0016] like Figure 1 As shown, the utility model discloses a fiberglass reinforced plastic pipe lining device, including a frame 1 fixed on a winding trolley, and a cylinder 2, a roller 3 and a glue groove 4 are provided on the frame 1 from left to right; the cylinder 2 is arranged obliquely, and a hair roller 5 is provided on the piston rod of the cylinder 2; a lining felt roll 6 is sleeved on the roller 3, one end of the roller 3 is rotatably connected to the frame 1, and the other end is provided with a nut 10, and the nut 10 is threadedly connected to the roller 3, so as to facilitate the replacement of lining felt rolls 6 of different sizes; the glue groove 4 is connected to the frame 1 through a connecting rod 7, and a positioning hole is provided on the connecting rod 7, and the connecting rod 7 is fixed to the frame 1 by a bolt through the positioning hole; the cross-section of the glue groove 4 is an inverted trapezoidal structure, and three rows of staggered leakage holes 8 are provided at the bottom of the glue groove 4; it also includes a mold 9, and the mold 9 is located below the glue groove 4.

[0017] Working principle: When in use, first pull the lining felt onto the mold 9, the winding trolley drives the device to move, the glue in the glue tank 4 drips evenly onto the mold 9, and the lining felt is wound onto the rotating mold 9. During the winding process, the cylinder 2 extends, so that the hair roller 5 abuts against the mold 9, which is conducive to pressing the lining felt so that it is soaked with glue and applied to the mold 9.
