Technical Field

[0001] The utility model relates to the technical field of oil pipelines, in particular to an adjustable bolt fastening clamp. Background Technique

[0002] Oil and gas transportation pipelines are widely used in the production and transportation process of the petrochemical industry. During operation, they are usually affected by various factors and various defects appear, such as corrosion, inevitable scratches, cracks and slag inclusions caused by welding. The existence and development of these defects will pose a direct threat to the safety of the pipeline. If the method of replacing the pipeline is adopted, not only the construction period is long, the cost is high, but also the normal transportation work is affected. The existing oil pipelines use materials such as repair resin to repair the damaged parts of the pipeline to prevent it from deteriorating further. Since the repair resin is usually liquid, and the outer wall of the oilfield pipeline is curved, directly applying the repair resin to the damaged part of the pipeline will cause the repair resin to slide off, and very little repair resin can adhere to the damaged part, resulting in a very poor repair effect. Therefore, a clamp that can fix the repair resin during repair is needed to improve the repair effect of the damaged pipeline;

[0003] In the prior art, such as CN218671147U discloses a bolt fastening clamp for an oil pipeline. When repairing an oil pipeline, first select a suitable arc-shaped plate and place it on the outer wall of the oil pipeline, so that the sealing ring adheres to the outer wall of the oil pipeline, then dock the upper sleeve and the lower sleeve, and the first ear plate and the second ear plate are in contact, and are connected by matching the fastening bolt and the nut, so that the top of the arc-shaped plate contacts the fixed rod, thereby fixing the arc-shaped plate on the oil pipeline;

[0004] However, the gap between its upper sleeve and lower sleeve is fixed. When used on oil pipelines of different sizes, the adjustment range is limited, and it is inconvenient to adjust to adapt to the oil pipeline for clamping, thereby reducing the flexibility. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the present utility model provides a technical solution: an adjustable bolt fastening fixture, including a fixing bracket 1 and a pipeline main body 2. The pipeline main body 2 is movably clamped inside the fixing bracket 1, and a pressing assembly 3 and a filling assembly 4 are movably installed above the fixing bracket 1;

[0025] The fixing bracket 1 includes a cross plate 11, a first clamping bracket 12 and a second clamping bracket 13. The first clamping bracket 12 is fixedly connected to the top of the cross plate 11. A through groove 14 is formed inside the first clamping bracket 12. Through holes 15 which are symmetrically arranged left and right are formed at the bottom of the cross plate 11. A long bolt rod 17 is movably clamped inside the through hole 15. Through holes 16 which are symmetrically arranged left and right are formed inside the left and right parts of the second clamping bracket 13. The long bolt rod 17 is movably clamped inside the through hole 16. The second clamping bracket 13 is located inside the through groove 14. A locking nut 18 which is located above the through hole 16 is movably installed outside the through hole 15.

[0026] The bottom of the locking nut 18 is in close fit with the top of the second clamping bracket 13, which is used to lock and fix the long bolt rod 17 inside the through hole 15 and the through hole 16. The second clamping bracket 13 can move inside the through groove 14. Furthermore, the distance between the second clamping bracket 13 and the first clamping bracket 12 can be adjusted by operating the locking nut 18, which is convenient for clamping and fixing pipe bodies 2 of different sizes, enabling the fixing bracket 1 to be adjusted according to pipe bodies 2 of different sizes, achieving stable clamping and improving flexibility.

[0027] Both the first clamping bracket 12 and the second clamping bracket 13 are arranged in a "V" shape, and the inner sides of the first clamping bracket 12 and the second clamping bracket 13 are arranged oppositely, enabling the first clamping bracket 12 and the second clamping bracket 13 to better fit the outer surface of the pipe body 2. The pointed part of the "V" - shaped structure can exert a certain squeezing effect on the pipe body 2, further enhancing the fixing effect, enabling the two to tightly clamp the pipe body 2 under the action of the locking nut 18, preventing it from shaking or displacing during the working process, and ensuring the stability and reliability of the entire fixing bracket 1.

[0028] The width of the second clamping bracket 13 is adapted to the width of the through groove 14, and the second clamping bracket 13 is movably clamped inside the through groove 14. When adjusting the distance, the second clamping bracket 13 can slide smoothly along the through groove 14 without jamming or deviation.

[0029] A gasket 19 which is located below the locking nut 18 is movably sleeved outside the through hole 15, which can effectively increase the contact area between the locking nut 18 and the fixing bracket 1, disperse the pressure generated by the locking nut 18 on the fixing bracket 1 when tightened, and at the same time can also play a certain buffering role, reducing the loosening that may occur to the locking nut 18 after long - term use.

[0030] Please refer to Figure 4, the pressing component 3 includes a tightening bolt 31 and a limiting rod 32 that are movably clamped inside the second clamping frame 13. A pressing block 33 is fixedly installed at the bottoms of the tightening bolt 31 and the limiting rod 32. A clamping groove 34 is provided at the top of the second clamping frame 13. An adjusting nut 35 is movably clamped inside the clamping groove 34. The adjusting nut 35 is threadedly connected to the outside of the tightening bolt 31. By rotating the adjusting nut 35, the tightening bolt 31 and the limiting rod 32 can be pushed to move downward along the inner wall of the second clamping frame 13, so that the pressing block 33 pushes the filling component 4 to closely fit on the outer surface of the pipeline main body 2, enhancing the connection precision and facilitating operation at the same time.

[0031] The limiting rod 32 is arranged in front of the tightening bolt 31. The filling component 4 is movably clamped inside the pressing block 33, so that when the filling component 4 is subjected to the thrust of the pressing block 33, it can fit more evenly and stably on the outer surface of the pipeline main body 2, avoiding the situation of connection looseness or poor sealing caused by uneven force.

[0032] Please refer to Figure 4 , the filling component 4 includes an arc-shaped cover 41. A sealing ring 42 is fixedly clamped at the bottom of the arc-shaped cover 41. An injection port 43 and an exhaust port 44 are provided at the top of the arc-shaped cover 41. The injection port 43 is used to inject filling material into the arc-shaped cover 41. By filling the gap between the arc-shaped cover 41 and the pipeline main body 2 with the filling material, a better sealing effect is achieved. The exhaust port 44 is used to discharge the air inside the arc-shaped cover 41 when injecting the filling material, avoiding the existence of air bubbles in the filling material and affecting the sealing performance.

[0033] Working principle: By arranging the first clamping frame 12 outside the pipeline main body 2, passing the long bolt rod 17 through from below the first through hole 15, and then correspondingly clamping the second clamping frame 13 from above the through slot 14, so that the first through hole 15 passes through the second through hole 16 on the side of the second clamping frame 13. At this time, the second clamping frame 13 is clamped outside the pipeline main body 2. Use the locking nuts 18 to tighten from above the first through holes 15 on both sides, so that the repaired part of the pipeline main body 2 is located inside the pressing component 3. Push the second clamping frame 13 to move inward along the through slot 14 through the locking nut 18 from outside the second through hole 16 for locking. Continuously turn the locking nut 18 to make the second clamping frame 13 move inside the through slot 14 and continuously tighten with the first clamping frame 12 to clamp the pipeline main body 2. Then select a suitable filling component 4 to fit on the repaired part of the pipeline main body 2, make it located inside the pressing block 33, and turn the adjusting nut 35 clamped in the clamping groove 34, so that the adjusting nut 35 drives the tightening bolt 31 threadedly connected to its inner side to slide inward along the inside of the second clamping frame 13. With the cooperation of the limiting rod 32 and the tightening bolt 31 for guiding, the pressing block 33 presses the arc-shaped cover 41 against the pipeline main body 2. Ensure sealing through the sealing ring 42, and inject repair resin from the injection port 43 for repair.

[0034] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
