Description

Technical Field

[0001] This utility model relates to the field of road crack sealing technology, specifically a road crack sealing device with positioning function. Background Technology

[0002] Asphalt pavement crack sealing technology is an effective preventive protection method. It is a preventive maintenance procedure for pavements with good original base and cross-section, where only longitudinal and transverse cracks appear on the surface, accompanied by numerous fine, expanding cracks, and with a relatively low crack density. Crack sealing prevents water penetration: cracks on the road surface provide channels for water to enter the pavement structure. Water intrusion leads to softening of the subgrade and reduced strength of the base layer, thus accelerating pavement damage. Crack sealing effectively seals the cracks, preventing water penetration and protecting the integrity of the road structure.

[0003] Currently, road crack sealing devices deliver crack sealant to road cracks through connecting pipes, and then fill the cracks using the properties of the sealant. However, the current sealing process requires workers to hold the connecting pipe and slide it along the crack while the sealant is delivered to the crack. This method requires workers to hold the connecting pipe for a long time, which is physically demanding. Moreover, holding the connecting pipe can easily cause it to deviate from the crack, resulting in sealant flowing onto the ground and being wasted. Utility Model Content

[0004] The purpose of this invention is to provide a road crack sealing device with positioning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road crack sealing device with positioning function, comprising a support rod, rollers on both sides of the support rod, support groove rods on both sides of the top of the support rod, a telescopic plate for adjusting height inside the support groove rod, a connecting plate inside the telescopic plate, a push rod on the left side of the telescopic plate, a crack sealing component at the top of the telescopic plate, and a fixing component inside the bottom of the support groove rod.

[0006] Preferably, the inner side of the support groove rod is provided with a through hole for fixing the telescopic plate after adjustment.

[0007] Preferably, the rollers are tilted outwards to improve stability during the pushing process and prevent deviation during pushing.

[0008] Preferably, the crack filling assembly includes a fixing block, which is disposed at the top of the telescopic plate. A connecting pipe is disposed inside the fixing block, and the left side of the connecting pipe is connected to the crack filling adhesive device.

[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 1-4 This utility model provides a technical solution for a road crack sealing device with positioning function: A road crack sealing device with positioning function includes a support rod 1, rollers 2 on both sides of the support rod 1, and support groove rods 3 on both sides of the top of the support rod 1. The support groove rods 3 are used to support the telescopic plate 4. The telescopic plate 4 is provided inside the support groove rod 3 for adjusting the height. The telescopic plate 4 is used to adjust the height of the crack sealing component. A connecting plate 5 is provided on the inner side of the telescopic plate 4. A push rod 6 is provided on the left side of the left telescopic plate 4. The push rod 6 is used to push the connecting pipe 8 to move during the crack sealing process. The crack sealing component is provided at the top of the telescopic plate 4. A fixing component is provided on the inner side of the bottom of the support groove rod 3. A through hole is opened on the inner side of the support groove rod 3 for fixing the telescopic plate 4 after adjustment. The rollers 2 are tilted outward to improve the stability during the pushing process and prevent deviation during the pushing process.

[0024] The crack filling assembly includes a fixing block 7, which is located at the top of the telescopic plate 4. The fixing block 7 is used to support the connecting pipe 8. The connecting pipe 8 is installed inside the fixing block 7. The connecting pipe 8 delivers crack filling adhesive to the road crack for filling, and the left side of the connecting pipe 8 is connected to the crack filling equipment.

[0025] The fixing assembly includes a fixing rod 9, which is threaded inside the support groove rod 3. The fixing rod 9 moves outward and presses against the outer wall of the telescopic plate 4 to fix it. A limit groove rod 10 is provided inside the fixing rod 9. A rotating rod 11 for transmission is provided inside the limit groove rod 10. When the rotating rod 11 rotates, it can drive the fixing rod 9 to rotate simultaneously through the limit groove rod 10. Then, the fixing rod 9 is threadedly connected to the support groove rod 3. The fixing rod 9 moves outward and fixes the telescopic plate 4. A limit block 12 is machined inside the connection between the rotating rod 11 and the limit groove rod 10. A limit groove is opened inside the limit groove rod 10. The outer wall of the fixing rod 9 is threaded.

[0026] Working Principle: When using a road crack sealing device with positioning function, the user first pushes the entire device to the location requiring sealing using the push rod 6. Then, the user aligns the bottom end of the connecting pipe 8 with the crack. The user then controls the sealing adhesive device via an external control unit to deliver the adhesive into the connecting pipe 8, which then flows out from the other end to fill the crack. During the sealing process, the user pushes the push rod 6 forward, and the position of the connecting pipe 8 follows the crack. The tilting characteristic of the roller 2 maintains stability during movement, preventing the adhesive from flowing onto the ground due to deviation. After the crack is filled, the user rotates the rotating rod 11. As the rotating rod 11 rotates, it is guided by the limiting groove rod 10... The fixed rod 9 rotates simultaneously. The connection between the fixed rod 9 and the support groove rod 3 is threaded. When the fixed rod 9 rotates, it moves outward to disengage the telescopic plate 4. Then, the user pulls the telescopic plate 4 upward to lift it up. The upward movement of the telescopic plate 4 drives the fixed groove block 7 and the connecting pipe 8 to move upward simultaneously, so that the connecting pipe 8 is away from the ground. This prevents the connecting pipe 8 from contacting the ground and being damaged due to uneven road surfaces during normal movement. After the connecting pipe 8 is adjusted to a suitable height, the user rotates the rotating rod 11 in the opposite direction. The rotating rod 11 then drives the limit groove rod 10 and the fixed rod 9 to rotate simultaneously. During the rotation, the fixed rod 9 moves outward and inserts into the support groove rod 3 to press and fix the telescopic plate 4.
