[0002] In pipeline repair operations, the repair tape needs to be tightly fixed to the damaged area to ensure the repair's sealing and stability. Currently, most repair tape fixing clips suffer from poor adaptability, insufficient sealing, and cumbersome installation. Some clips cannot flexibly adjust their clamping range according to the pipe diameter, only adapting to a single pipe specification; furthermore, after fixing, leakage is easily caused by the lack of a sealing structure, affecting the repair effect; additionally, installation requires the use of multiple tools for gradual fixing, resulting in low operational efficiency and increased work time. Based on the aforementioned patent, which addresses the issues mentioned in its background technology regarding adaptability to only a single pipe specification and the ease with which leakage occurs due to the lack of a sealing structure, thus affecting the repair effect, this application proposes a pipeline repair tape fixing clip for excavation. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pipe repair clamp for excavation. The clamping range can be flexibly adjusted through the telescopic component, and the modular telescopic clamp can be adapted to excavated pipes of different diameters. The double sealing ring structure enhances the sealing performance after fixing and prevents water leakage. The combination of the lug, bolt, and fixing rod simplifies the installation operation, improves the fixing stability, and optimizes the practicality and work efficiency of the equipment as a whole.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A pipe repair clamp for excavation includes an upper clamp and a lower clamp at the bottom of the upper clamp. A telescopic component is provided on the rear side of the upper clamp. Two lugs are fixedly connected to the top of the upper clamp and the bottom of the lower clamp. An upper fixing block is fixedly connected to the left side of the upper clamp, and a lower fixing block is fixedly connected to the left side of the lower clamp. Both the upper fixing block and the lower fixing block are provided with threaded holes.

[0005] Furthermore, the telescopic assembly includes a slider base, with fixed blocks fixedly connected to both sides of the slider base, and a slider fixedly connected to the outer side of the slider base.

[0006] Furthermore, a nut is provided on the left side of the ear seat, and a fixing rod is threadedly connected to the inner side of the nut.

[0007] Furthermore, four telescopic clamps are slidably connected to the right side of the slider, and each telescopic clamp is composed of several telescopic clamp blocks.

[0008] Furthermore, a retaining sleeve is fixedly connected to the right side of the upper fixing clamp, and a rotating rod is rotatably connected to the upper part of the outer wall of the retaining sleeve.

[0009] Furthermore, the telescopic clamp has a slot on the left side and a threaded hole on the right side of the slot. A positioning rod is threaded into the inner side of the threaded hole, and nuts are threaded into both sides of the positioning rod. A clamping block is fixedly connected to the right side of the telescopic clamp, and positioning holes are provided on the front and rear sides of the clamping block.

[0010] Furthermore, a sealing ring groove is provided on the top of the telescopic clamping block, an elastic sealing ring is fixedly connected to the top of the sealing ring groove, and a waterproof sealing ring is fixedly connected to the top of the elastic sealing ring.

[0011] Furthermore, bolts are adapted to be connected in the threaded holes of the upper and lower fixing blocks, and anti-slip pads are provided on the heads of the bolts.

[0018] Referring to 3-6, a fixing block 9 is fixedly connected to the outer side of the upper fixing clamp 2. A slider base 10 is fixed to the right side of the fixing block 9. A slider 7 is fixedly connected to the outer side of the slider base 10. A nut 4 is provided on the left side of the ear seat 8. A fixing rod 3 is threadedly connected to the inner side of the nut 4. Upper fixing clamps 2 and lower fixing clamps 1 are provided on both sides of the fixing rod 3. Four telescopic clamps 5 are slidably connected to the right side of the slider 7. The telescopic clamps 5 are composed of several telescopic clamp blocks 6. A sleeve 12 is fixedly connected to the right side of the upper fixing clamp 2. A rotating rod 11 is rotatably connected to the upper outer wall of the sleeve 12. A locking mechanism is provided on the left side of the telescopic clamp block 6. The right side of the slot 13 has a threaded hole, and a positioning rod 14 is threadedly connected to the inside of the threaded hole. Nuts 4 are threadedly connected to both sides of the positioning rod 14. The right side of the telescopic clamping block 6 is fixedly connected to the clamping block 16. The clamping block 16 has positioning holes 17 on the front and rear sides. The top of the telescopic clamping block 6 has a sealing ring groove 15. An elastic sealing ring 22 is fixedly connected to the top of the sealing ring groove 15. A waterproof sealing ring 21 is fixedly connected to the top of the elastic sealing ring 22. Bolts 18 are fitted into the threaded holes of the upper fixing block 20 and the lower fixing block 19. The head of the bolt 18 is provided with an anti-slip pad.

[0019] Working Principle: Before use, the pipe diameter needs to be measured, and the specifications of the telescopic component should be adjusted according to the measurement data. The telescopic clamp 5 is slid to the preset position on the slider base 10 using the slider 7, or the overall clamping range can be changed by increasing or decreasing the number of telescopic clamp blocks 6 to ensure precise matching with the pipe diameter. After adjustment, the positioning rod 14 is passed through the threaded hole of the telescopic clamp block 6, and the nuts 4 on both sides are tightened to complete the fixation. At this time, the stability of the telescopic structure is checked to ensure there is no loosening. The surface of the pipe to be repaired is cleaned to remove oil, rust, and impurities. The repair tape is cut to a suitable size according to the shape of the damaged area and covered on the damaged part of the pipe with the center aligned. A special pressure roller is used to roll along the surface of the repair tape to expel air between the repair tape and the pipe surface, ensuring a tight initial fit. The upper fixing clamp 2 and the lower fixing clamp 1 are respectively inserted from the upper and lower sides of the pipe, so that the repair tape is centered inside the fixing clamps. Initially position the fixing rod 3 and nut 4 at the operating lug 8. Rotate nut 4 clockwise until the fixing rod 3 generates pre-tightening force. At this point, the upper and lower fixing clamps should initially fit against the pipe surface, and the repair tape should be wrinkle-free. Take out the matching bolt 18, pass it through the corresponding threaded holes of the upper fixing block 20 and the lower fixing block 19, and tighten the bolt 18 clockwise using a torque wrench. Check whether the anti-slip pad is completely fitted against the surface of the fixing block to ensure there is no looseness or gap. Rotate the rotating rod 11 on the right side of the upper fixing clamp 2 until it engages with the corresponding slot of the lower fixing clamp 1. Apply appropriate pressure to ensure a tight fit. You can tap the end of the rotating rod 11 to make it fully engaged, completing the overall structure fixation. After fixation, check the status of the double sealing structure. The waterproof sealing ring 21 should completely cover the edge of the repair tape. A water spray test can be used to verify the sealing performance. Observe whether there is any water leakage on the inside. If there is no water leakage, the seal is qualified. Apply a uniform tensile force along the circumference of the fixing clamp to test the overall firmness. There should be no displacement at each connection point. Use a feeler gauge to check the gap between the fixing clamp and the pipe. If any loosening is found, it can be reinforced by fine-tuning the corresponding nut 4 or bolt 18 to ensure that the overall fixing effect meets the construction standards.
