Description

Technical Field

[0001] This utility model relates to the field of highway maintenance technology, specifically to a crack sealing pipe for highway maintenance. Background Technology

[0002] Crack sealing pipes are tools specifically designed for the repair of asphalt road surfaces. When used in conjunction with a filling pipe, crack sealing pipes inject sealant into the cracks in the road surface, thereby sealing the cracks. This effectively prevents moisture and other external factors from eroding the cracks, reduces the risk of further crack expansion, and thus extends the service life of the road surface.

[0003] Currently, when using crack sealing pipes, workers are prone to wrist and arm fatigue when holding the pipes for extended periods and controlling their angle. During prolonged crack sealing operations, fatigue can cause hand tremors, affecting the accuracy of the sealant application and thus impacting the effectiveness of road maintenance. Furthermore, some crack sealing pipes lack protection at the discharge end when not in use, making this end susceptible to damage from external forces. Additionally, after use, the scrapers used with some crack sealing pipes tend to accumulate a large amount of sealant, making it difficult for workers to disassemble and clean the fixed scrapers. The dried sealant can also affect the smoothness of the scraper surface, impacting its subsequent performance. Utility Model Content

[0004] The purpose of this utility model is to provide a crack sealing pipe for highway maintenance to solve the problems mentioned in the background art.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6As shown, a crack sealing pipe for highway maintenance includes a crack sealing pipe body 1 and a flexible hose 2 and an injection pipe 3 respectively connected to both ends of the crack sealing pipe body 1. Extension plates 4 are fixedly connected to both sides of the injection pipe 3. The surface of the extension plates 4 has a slot and is detachably connected to a scraping mechanism 5. A connecting frame 7 is fixedly fitted onto the surface of the crack sealing pipe body 1. A fixing mechanism 8 is provided on the surface of the connecting frame 7. A guide plate 10 is installed on the surface of the fixing mechanism 8. A positioning groove is provided on the surface of the guide plate 10. A movable frame 11 is slidably fitted onto the surface of the guide plate 10. A surface of the movable frame 11 is equipped with... The positioning mechanism 14, in conjunction with the positioning groove, can fix the relative position between the guide plate 10 and the moving frame 11. The top of the moving frame 11 is fixedly connected to the protective frame 15, which can protect the injection tube 3 and the scraping mechanism 5 when idle. The surface of the moving frame 11 is fixedly connected to the pulley 16, which can not only support the crack filling tube, but also increase the smoothness of the operation when the operator moves the crack filling tube, so as to reduce the fatigue caused by the operator lifting the crack filling tube body 1 for a long time and controlling the angle of the crack filling tube body 1.

[0024] The leveling mechanism 5 includes a convex plate 51, a rotating shaft 52, a scraper plate 53, and a spring 54. The convex plate 51 is detachably connected between two extension plates 4. There are two rotating shafts 52 and two springs 54. The two rotating shafts 52 rotate through the surfaces on both sides of the convex plate 51, and the two springs 54 are fixedly connected to the surfaces on both sides of the convex plate 51. The surface of the spring 54 contacts the surface of the extension plate 4. A locking block 6 is embedded in the surface of the spring 54. The surface of the locking block 6 contacts the inner wall of the locking groove. One end of the rotating shaft 52 is fixedly connected through the scraper plate 53. The operator installs the leveling mechanism 5 between the two extension plates 4 through the connection between the locking block 6 and the locking groove. Then the operator can rotate the scraper plate 53. At this time, the rotating shaft 52 can rotate accordingly so that one side of the bottom of the scraper plate 53 can contact the ground, thereby facilitating the use of the scraper plate 53 to level the potting compound.

[0025] The fixing mechanism 8 includes a smooth rod 81, a threaded cylinder 82, and a collar 83. One end of the smooth rod 81 is fixedly connected to the inner wall of the connecting frame 7. The threaded cylinder 82 is threaded through the surface of one side of the connecting frame 7 and is rotatably sleeved on the other end of the smooth rod 81. The collar 83 is fixedly sleeved on the surface of the threaded cylinder 82. The guide plate 10 is rotatably sleeved on the surface of the smooth rod 81, and the surface of the collar 83 is in contact with the surface of the guide plate 10. A clamping block 9 is fixedly connected to the inner wall of the connecting frame 7. The smooth rod 81 passes through the surface of the clamping block 9, and the surface of the guide plate 10 is in contact with the surface of the clamping block 9. When this grouting tube is in use, the operator can rotate the guide plate 10 and adjust the angle between the guide plate 10 and the grouting tube body 1. After that, the operator screws the threaded cylinder 82, and the collar 83 moves accordingly and comes into contact with the surface of the guide plate 10. At this time, the collar 83 and the clamping block 9 cooperate to fix the position of the guide plate 10 so that the grouting tube body 1 can be supported by the cooperation of the guide plate 10 and the moving frame 11.

[0026] Limiting blocks 12 are fixedly connected to the top and bottom of the guide plate 10. Limiting grooves 13 are opened at the top and bottom of the inner wall of the movable frame 11. The surface of the limiting block 12 is in contact with the inner wall of the limiting groove 13. The movement distance of the movable frame 11 of the guide plate 10 can be limited by the cooperation of the limiting block 12 and the limiting groove 13.

[0027] The positioning mechanism 14 includes a hollow cylinder 141, a positioning rod 142, a disc 143, and a compression spring 144. The hollow cylinder 141 is embedded in the surface of the movable frame 11. The positioning rod 142 slides through the hollow cylinder 141, and the surface of the positioning rod 142 contacts the inner wall of the positioning groove. The disc 143 is fixedly sleeved on the surface of the positioning rod 142. When the operator pulls the positioning rod 142, the disc 143 can be moved. At this time, the contact between the positioning rod 142 and the positioning groove is released. Then the operator can adjust the relative position between the movable frame 11 and the guide plate 10. Afterwards, under the action of the spring force of the compression spring 144, the positioning rod 142 and the positioning groove cooperate to fix the relative position between the guide plate 10 and the movable frame 11.

[0028] Working principle: The operator injects the sealing compound into the body of the crack filling tube 1 through the cooperation of the hose 2 and the discharge tube, in preparation for subsequent discharge using the injection tube 3. When using this crack filling tube, the operator can first pull the positioning rod 142 and pull the moving frame 11. At this time, the protective frame 15 moves and releases the protection of the injection tube 3 and the scraping mechanism 5. Then, the operator can rotate the guide plate 10 and push the moving frame 11 towards the direction of the fixing mechanism 8. Then, under the action of the compression spring 144, the positioning rod 142 cooperates with the positioning groove to fix the relative position between the moving frame 11 and the guide plate 10. After that, the operator can rotate the guide plate 10 and adjust the angle of the guide plate 10. After adjustment, the staff can move the collar 83 by turning the threaded cylinder 82. The collar 83 and the clamping block 9 can fix the angle of the guide plate 10. At this time, the pulley 16 is in contact with the ground. During this process, the staff can adjust the angle of the crack filling pipe body 1 when in use by adjusting the moving position of the moving frame 11 and the rotation angle of the guide plate 10. The staff can rotate the scraper plate 53 until the bottom of the scraper plate 53 is in contact with the ground. When the sealant is injected into the road crack through the injection pipe 3, the guide plate 10, the moving frame 11 and the pulley 16 can support the crack filling pipe body 1 when the staff moves the crack filling pipe. The scraper plate 53 can scrape the sealant on the road surface.

[0029] After the grouting operation is completed, the workers can squeeze the spring 54 and pull the mortise plate 51 to remove the entire scraping mechanism 5. After that, the workers can soak the scraping mechanism 5 in hot water to clean the potting compound adhering to the surface of the scraping mechanism 5 for subsequent operations.
