Description

Technical Field

[0001] This utility model relates to the field of road and bridge crack repair technology, specifically a portable road and bridge structural crack repair device. Background Technology

[0002] As a key component of modern transportation networks, roads and bridges bear heavy transportation tasks. The integrity and stability of their structures play a vital role in ensuring traffic safety and promoting regional economic development. However, due to repeated vehicle loads, environmental factors, and material aging, road and bridge structures are prone to cracks. These cracks not only reduce the aesthetics of roads and bridges, but more seriously, if not repaired in time, they will gradually develop and expand, weakening the structural load-bearing capacity and shortening the service life of roads and bridges. Therefore, a portable road and bridge structural crack repair device is needed to repair cracks.

[0003] However, due to the poor adjustment and support capabilities of existing portable road and bridge structural crack repair devices, it is not convenient to install and adjust the repair device according to the needs of use. During use, it can only be manually picked up and controlled by manpower, which is labor-intensive when repairing and relocating, increases the amount of manual labor, and reduces repair efficiency.

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a portable road and bridge structural crack repair device, including a placement and adjustment frame 1, a repair tube 2 movably installed at the top of the placement and adjustment frame 1, support sleeves 3 fixedly installed on the inner sides of the placement and adjustment frame 1, connecting telescopic frames 4 movably installed on the adjacent sides of the support sleeves 3, the connecting telescopic frames 4 extending into the interior of the support sleeves 3, fixing plates 5 fixedly installed on the adjacent sides of the connecting telescopic frames 4, rubber pads 6 fixedly installed on the adjacent sides of the fixing plates 5, and the placement and adjustment frame 1 fixed at the middle of the fixing plates 5. A connecting spring 7 is installed, which is sleeved on the outer end of the support sleeve 3 and the connecting telescopic frame 4. Support rotating rods 8 are rotatably connected to both sides of the adjustment frame 1. Moving rollers 9 are fixedly installed on both sides of the support rotating rods 8. The connecting spring 7 drives the connecting telescopic frame 4 to slide inside the support sleeve 3, thereby driving the fixed plate 5 and the rubber pad 6 to move. The rubber pad 6 facilitates the clamping and placement of both sides of the repair tube 2. Lifting the repair tube 2 drives the support rotating rods 8 to rotate on both sides of the adjustment frame 1, thereby facilitating the adjustment of the use angle of the repair tube 2.

[0023] A connecting pipe seat 10 is fixedly installed on one side of the repair pipe body 2. The outer end of the connecting pipe seat 10 has an external thread 11. A sealing cap 12 is threaded onto the outer end of the connecting pipe seat 10. An internal thread 13 is provided on the inner side of the sealing cap 12. A push rod 14 is movably installed in the middle of the sealing cap 12. A limit push plate 15 is fixedly installed on one side of the push rod 14. A compression push plate 16 is fixedly installed on the side of the push rod 14 away from the limit push plate 15. The compression push plate 16 is located inside the repair pipe body 2. A sealing ring 17 is fixedly installed on the outer end of the compression push plate 16. A discharge connecting pipe 18 is fixedly installed on the side of the repair tube body 2 away from the connecting pipe seat 10. A repair discharge pipe 19 is threadedly connected to the side of the discharge connecting pipe 18 away from the repair tube body 2. A repair discharge head 20 is fixedly installed on the side of the repair discharge pipe 19 away from the discharge connecting pipe 18. A sealing plug 21 is movably installed inside the repair discharge head 20. The push limit plate 15 applies pressure to the push rod 14, which drives the extrusion push plate 16 to move inside the repair tube body 2, and discharges the repair agent through the discharge connecting pipe 18, the repair discharge pipe 19 and the repair discharge head 20.

[0024] Working principle: When repairing cracks in road surfaces and bridges, the crack repair agent is first injected into the repair tube 2. The sealing cap 12 and the connecting tube seat 10 are threaded together via the internal thread 13 and the external thread 11, thereby placing the extrusion push plate 16 into the repair tube 2. The repair tube 2 is then placed on the adjustment frame 1, positioned in the middle of the rubber pad 6. The connecting spring 7 is compressed, causing the connecting telescopic frame 4 to slide within the support sleeve 3, thus moving the fixing plate 5 and the rubber pad 6. The rubber pad 6 facilitates clamping and placement of the repair tube 2 on both sides and allows for easy disassembly. To facilitate the installation and support of the repair tube 2, the sealing plug 21 is then removed, and the limiting push plate 15 is pushed to apply pressure to the push rod 14, causing the extrusion push plate 16 to move inside the repair tube 2. The repair agent is discharged through the discharge connection pipe 18, the repair discharge pipe 19, and the repair discharge head 20 to repair the crack. During repair, the repair tube 2 is lifted to drive the support rotation rod 8 to rotate on both sides of the placement adjustment frame 1, thereby facilitating the adjustment of the use angle of the repair tube 2 and making it easy to repair the crack according to the repair needs. The use position of the repair tube 2 can be adjusted by moving the roller 9, improving repair efficiency and making it easy to carry and operate.
