Description

Technical Field

[0001] This utility model belongs to the field of pipeline repair technology, and in particular relates to a device for accelerating the curing of thermosetting resins for pipeline repair. Background Technology

[0002] Thermosetting resin is a material that undergoes a chemical reaction and cures under heating conditions. It is often used for trenchless pipeline repair. After curing, it adheres tightly to the inner wall of the pipeline to form a structural lining. The equipment used to accelerate the curing of thermosetting resin in pipeline repair is the ultraviolet curing system. By pulling the resin-impregnated fiberglass hose into the old pipe, the resin is promoted to cure quickly and form a new pipeline lining.

[0003] The following problems exist in the application of thermosetting resin accelerated curing devices for pipe repair on the market: Traditional thermosetting resin accelerated curing devices for pipe repair usually use ultraviolet irradiation to solidify the resin on the outside of the pipe. However, after long-term exposure to ultraviolet light, it is easy to cause skin and eye damage to the surrounding workers. The side effects are relatively strong, so the safety of resin curing is poor when using it. Utility Model Content

[0020] To better understand the purpose, structure, and function of this utility model, the following detailed description of a thermosetting resin accelerated coagulation device for pipeline repair, in conjunction with the accompanying drawings, is provided.

[0021] like Figure 1-4 As shown, this utility model discloses a thermosetting resin accelerated curing device for pipe repair, comprising an upper shell 2 and a lower shell 1. The bottom of the upper shell 2 is connected to the lower shell 1 via a pivot. A clamping seat 3 is provided on the inner side of the upper shell 2, and a clamping seat 3 is also provided inside the lower shell 1. A heating tube 24 is installed inside the clamping seat 3, a fixing frame 4 is provided on the outer side of the heating tube 24, and a mesh cover 5 is provided on the inner side of the fixing frame 4. A first dustproof plate 17 is connected to the outer side of the upper shell 2 via a pivot, and a second dustproof plate 18 is connected to the side of the first dustproof plate 17 via a pivot. Mounting plates 22 are provided on the side of the lower shell 1, and the mounting plates 22 are symmetrically distributed. Mounting grooves 23 are formed on the inner side of the mounting plates 22. The presence of mounting plates 22 and mounting grooves 23 facilitates the installation of the curing device. Place it stably on a flat surface, remove the fasteners that penetrate the mounting slot 23, install a handle 21 on the top of the upper housing 2, connect the upper housing 2 to the top of the lower housing 1 via a pivot, and install a clamping seat 3 and a heating tube 24 on the inner side of the housing structure. Install a dustproof structure on the outside of the housing structure. After applying resin glue to the outside of the damaged pipe, open the dustproof structure in the opposite direction, open the upper housing 2, install the lower housing 1 on the outside of the pipe, and tighten the fastening structure to assemble the housing structure. Then, start the temperature control device and heating device to control the temperature of the heating tube 24, which will allow the resin glue to solidify quickly. After the solidification time is over, the solidification device can be disassembled. Avoid solidification by ultraviolet light, which makes it safe to use.

[0022] The upper housing 2 has a slot 13 on its side, and the lower housing 1 has a plate 12 on its top. The plate 12 is embedded in the slot 13. The plate 12 and the slot 13 facilitate the initial splicing of the upper housing 2 and the lower housing 1.

[0023] The first dustproof plate 17 has a metal sheet 19 on its side, and the second dustproof plate 18 has a magnetic absorbing sheet 20 on its outer side. The magnetic absorbing sheet 20 magnetically attracts the metal sheet 19. By installing the metal sheet 19 and the magnetic absorbing sheet 20, the metal sheet 19 can be attracted by strong ferromagnetic force, and the first dustproof plate 17 and the second dustproof plate 18 can be spliced ​​together.

[0024] The top of the upper housing 2 is connected to a fixed frame 14. The inside of the fixed frame 14 is provided with a telescopic plate 15. The top of the telescopic plate 15 is provided with a rubber clamping plate 16. Due to the installation of the fixed frame 14 and the telescopic plate 15, the position of the rubber clamping plate 16 can be adjusted at any time, which facilitates the subsequent limiting work of the dustproof plate structure.

[0025] The lower housing 1 has a fixing plate 6 on its side, a shaft 7 on its side, a bushing 8 on the outside of the shaft 7, and a ball screw 9 on the outside of the bushing 8. The fixing plate 6 facilitates the installation of the shaft 7 and the bushing 8 on the outside of the lower housing 1.

[0026] The external thread of the ball screw 9 is connected to the locking nut 10. The outer side of the upper housing 2 is provided with a limiting plate 11. The ball screw 9 is embedded in the inner side of the limiting plate 11. Since there is a locking nut 10, a ball screw 9, and a limiting plate 11, after the ball screw 9 is installed on the inner side of the limiting plate 11, the external locking nut 10 can be turned to lock and fix it.

[0027] The working principle of this thermosetting resin accelerated curing device for pipeline repair is as follows: When using the device, firstly, the pipeline to be repaired needs to be removed and its surface cleaned. Next, the resin adhesive is prepared according to the formula. Then, the applicator is held and dipped into the resin adhesive liquid for uniform stirring. After stirring, it is directly applied to the repair area. After the worker has applied it evenly, they hold handle 21 and move the curing device to the outside of the pipeline to be repaired. Then, they hold handle 21 to open the upper housing 2 and move the lower housing 1 to the outside of the pipeline. The upper housing 2 is then closed in the opposite direction. The worker then rotates the bushing 8 outside the shaft 7 to insert the ball screw 9 into the inner side of the limiting plate 11. Subsequently... Simply tighten the external locking nut 10 to secure it, thus completing the initial assembly. Next, pull the first dustproof plate 17 and the second dustproof plate 18 to rotate them in opposite directions. Then, pull the telescopic plate 15 inside the fixing frame 14 again to install the rubber clamp 16 on the outside of the dustproof plate structure for limiting its position. Then, start the heating device (model DJR-B2-1500W) and the temperature control device (model E5AZ-C3) to control the heating temperature. Finally, start the heating device and the temperature control device to solidify the resin glue applied to the outside of the pipe through the heating tube 24 installed inside.
