Description

Technical Field

[0001] This invention relates to the field of in-situ pipeline repair technology, and more specifically, to a device for grinding thermosetting resin glass fiber prepreg for in-situ pipeline repair. Background Technology

[0002] In-situ pipeline repair, also known as CIPP in-situ curing, is a trenchless repair process for underground pipelines. It is currently the most widely used trenchless repair technology for underground pipelines worldwide, and it is widely applied in the trenchless repair of gravity flow pipelines, water supply, gas and other pressure pipelines. Its working principle is to use hydraulic or pneumatic pressure to flip a non-woven fabric liner or fiberglass pre-impregnated with polyester resin or vinyl ester resin into the damaged area inside the pipeline to be repaired. Then, ultraviolet (UV) heating is used to heat and cure the non-woven fabric liner or fiberglass pre-impregnated with polyester resin or epoxy resin, forming a new continuous pipeline with full structural strength at the damaged area of ​​the underground pipeline, thereby achieving trenchless repair of underground pipelines.

[0003] Currently, the construction steps of in-situ repair technology for underground pipelines are mainly divided into two parts: above-ground operations and underground operations. Above-ground operations mainly involve the preparation of thermosetting resin glass fiber prepreg and the adhesive coating process for non-woven fabric lining tubes or glass fiber tubes. However, the existing adhesive coating process for non-woven fabric lining tubes or glass fiber tubes mainly involves manually pouring the prepared thermosetting resin glass fiber prepreg onto the pre-laid non-woven fabric lining tube or glass fiber tube, and then using a scraper to roll and flatten the prepreg on the non-woven fabric lining tube or glass fiber tube. The efficiency of manual adhesive rolling is low, and a large amount of prepreg drips onto the adhesive rolling base plate (waterproof cloth) during the rolling process, resulting in a waste of prepreg resources. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a thermosetting resin glass fiber prepreg rolling device for in-situ pipeline repair. This addresses the problem that in existing in-situ underground pipeline repair technologies, the adhesive coating process for non-woven fabric liners or glass fiber tubes is primarily done manually. The prepared thermosetting resin glass fiber prepreg is poured onto the pre-laid non-woven fabric liner or glass fiber tube, and then a scraper is used to roll and flatten the prepreg on the non-woven fabric liner or glass fiber tube. Manual rolling is inefficient, and a large amount of prepreg drips onto the rolling base plate (waterproof cloth) during the rolling process, resulting in a waste of prepreg resources.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a thermosetting resin glass fiber prepreg applicator for in-situ pipe repair, comprising a support base, a pulley base fixedly installed on the bottom surface of the support base, an applicator platform provided between the support base and the pulley base, a pressurizing unit and a storage box installed side by side on the top surface of the support base, a spray gun storage side box fixedly connected to the pulley base below the pressurizing unit, a residual glue recycling box detachably snapped onto the pulley base below the storage box, and a crossbar handle fixedly installed on the side of the storage box away from the pressurizing unit.

[0006] Preferably, the pulley base includes a pressure-bearing base plate, and support columns that are fixedly connected to the bottom surface of the support base plate are fixedly installed at the four corners of the top surface of the pressure-bearing base plate. Universal pulleys are fixedly installed at the four corners of the bottom surface of the pressure-bearing base plate, and receiving slots that are adapted to the rubber rolling platform are opened on the side of the pressure-bearing base plate.

[0007] Preferably, the spray gun storage box is fixedly installed on one side of the top surface of the pressure-bearing base plate by two of the support columns, the excess glue recovery box is detachably snapped onto the other side of the top surface of the pressure-bearing base plate by the other two support columns, and the glue-grinding platform is arranged between the four support columns.

[0008] Preferably, the rubber grinding platform includes a U-shaped connecting groove plate and a concave rubber grinding table. The outer side of the U-shaped connecting groove plate is fixedly connected to four supporting columns. Sliding support frames are provided on both sides of the U-shaped slot of the U-shaped connecting groove plate, which are fixedly connected to the two sides of the concave rubber grinding table. The concave rubber grinding table is slidably connected to the U-shaped connecting groove plate through two sets of sliding support frames.

[0009] Preferably, the bottom plate of the concave rubber grinding table is magnetically connected to a magnetic scraper, the inclined surface of the magnetic scraper is magnetically connected to a movable scraping block, and a flow guide pipe is connected through a corner on the outer side of the concave rubber grinding table, the flow guide pipe being slidably connected to the receiving groove.

[0010] Preferably, the outer side plate of the concave glue-grinding table is made of fiberglass material, the bottom plate of the concave glue-grinding table is made of magnetic alloy material, the magnetic scraper is made of magnetic material, the moving scraper block is made of magnetic alloy material, and the inner wall of the flow-guiding glue pipe is provided with vertical flow-guiding grooves.

[0011] Preferably, the pressurizing unit includes a box-type accumulator tank, which is fixedly installed on the top surface of the supporting base plate. A pressurizing air pump is fixedly connected to the pressurizing air inlet at the top of the box-type accumulator tank. A dust filter element is detachably installed at the air inlet at the top of the pressurizing air pump. An air tube coiler is fixedly installed on the side of the box-type accumulator tank away from the storage box.

[0012] Preferably, the tracheal constrictor has a pressurized air tube wound inside by a return spring coil. One end of the pressurized air tube wound inside the tracheal constrictor is connected to the pressurized air outlet on the side of the box-type accumulator, and the other end of the pressurized air tube wound inside the tracheal constrictor is exposed at the outlet port at the bottom of the tracheal constrictor housing.

[0013] The technical effects and advantages of this invention are as follows:

[0014] In the above scheme, the glue-rolling platform is slidably installed directly below the pressurizing unit and the storage box via a pulley base and a supporting base. The pressurizing unit is connected to the pneumatic glue-spraying gun inside the spray gun storage box via an extended air pipe. During the operation of the device, the pressurizing unit, in conjunction with the pneumatic glue-spraying gun inside the spray gun storage box, uniformly sprays thermosetting resin glass fiber prepreg onto the surface of the nonwoven fabric lining tube or glass fiber tube. This ensures the uniformity of the thermosetting resin glass fiber prepreg coating on the surface of the nonwoven fabric lining tube or glass fiber tube, and avoids the time-consuming and laborious problem of traditional manual scraping glue rolling, thereby improving the prepreg coating efficiency of the nonwoven fabric lining tube or glass fiber tube.

[0015] In the above scheme, the excess glue recovery box is detachably installed on the side of the glue-rolling platform via a pulley base. After the prepreg coating operation is completed by laying the non-woven fabric liner tube or fiberglass tube inside the glue-rolling platform, the excess glue is collected and recovered by the glue scraping component inside the glue-rolling platform in conjunction with the excess glue recovery box, thereby avoiding the waste of prepreg resources and saving the raw material cost of in-situ pipeline repair.

[0016] In the above solution, the supporting base and pulley base integrate the pressurizing unit, storage box, spray gun storage box, residual glue recycling box and glue grinding platform into a whole. The storage box is equipped with a horizontal handle on the side. After the underground pipeline is repaired in situ, the engineering waste can be collected in the storage box. Then, the pulley base and horizontal handle can be used to move the entire glue grinding device by hand, which improves the ease of use of the device. Attached Figure Description

The two sets of sliding support frames 32 can provide support for the concave rubber grinding table 33 when it is in the outward pulling state, avoiding the problem of the outer end tilting and being difficult to retract when the concave rubber grinding table 33 is suspended outward.

[0030] The concave grinding table 33 has a magnetically attached magnetic scraper 34 connected to the bottom plate of its inner cavity.

Then, pour the prepared thermosetting resin fiberglass prepreg into the glue storage tank of the air pressure glue gun and perform pressurized glue coating. After the non-woven fabric liner tube or fiberglass tube has completed the prepreg coating, take it out from inside the concave glue-grinding table 33, and scrape the remaining glue inside the concave glue-grinding table 33 with the magnetic scraper 34 and the moving scraper block 35. Finally, discharge the scraped remaining glue into the remaining glue recovery box 7 through the guide glue discharge pipe 36 for storage and later use.
