Description

Technical Field

[0001] The present application relates to the technical field of road maintenance equipment, and more specifically, to a highway crack detection and repair device. Background Art

[0002] After a highway is built and opened to traffic, its quality will gradually decline due to the wear and impact of wheels, erosion and weathering by natural forces such as rainstorms, floods, sandstorms, ice and snow, sunlight, ice melting, as well as human damage and certain defects left over from construction. Therefore, after a highway is built and opened to traffic, maintenance measures must be taken and it must be continuously updated and improved. Highway maintenance must repair damaged parts in a timely manner, otherwise it will lead to increased investment in repair projects and shorten the service life of the highway.

[0003] The document with the prior art announcement number CN219908522U provides a road crack repairing device, which relies on the supporting force of the L-shaped support rod to slide the rolling wheel onto the L-shaped support rod, and then fully rolls the asphalt through the rolling wheel, so that the asphalt filled in the crack is smoother, and then the scraper fixedly connected to the right end below the sliding rod is used to scrape off the excess asphalt when filling the crack while pushing the device to move, so as to effectively ensure the smoothness of the road after the repair; through the cooperation of the fixed clamping ring and the T-shaped clamping ring fixedly connected to the outer wall of the lower end of the conveying pipe, the asphalt transported out of the conveying pipe is controlled to have different flow rates, and at the same time, the T-shaped clamping ring is limited by the semicircular block and the reset spring on the outer wall of the T-shaped clamping ring. When the T-shaped clamping ring is rotated, the semicircular notch of the T-shaped clamping ring will move with the semicircular notch in the fixed clamping ring, and the flow rate of the conveying pipe can be effectively controlled by adjusting the size of the notch.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, when the cracks are small, it is difficult for asphalt to fill the gaps, so it is necessary to use a thinner needle tube for injection repair. In view of this, we propose a road crack detection and repair device. Utility Model Content
