Description

Technical Field

[0001] This invention belongs to the field of municipal road maintenance technology, and in particular relates to a device and method for rapid repair of cracks in municipal roads. Background Technology

[0002] The rapid crack repair device for municipal roads is a highly efficient and convenient road maintenance equipment, primarily used for quickly repairing cracks in asphalt or concrete pavements. Its core function lies in significantly improving crack repair efficiency through automated or semi-automated operation, reducing the time-consuming and traffic-disrupting nature of traditional manual repairs. This device can accurately identify crack locations and employs techniques such as high-temperature fusion, filling with sealant, or injecting sealant to ensure a smooth, durable, and waterproof repair surface. Its rapid response characteristics are particularly suitable for high-traffic areas such as urban arterial roads and highways, allowing for quick repairs and minimizing traffic disruption. Furthermore, this device is typically environmentally friendly, avoiding excessive waste or harmful gases generated during the repair process. By regularly using this equipment, municipal departments can effectively extend road lifespan, reduce long-term maintenance costs, and improve driving safety and road aesthetics, making it an important component of modern intelligent urban road maintenance systems.

[0003] Existing rapid crack repair devices for municipal roads have been found to have shortcomings during use. Most of them directly fill the cracks with filler, which can easily lead to cracking again due to insufficient filling, resulting in unsatisfactory repair results.

[0004] In view of this, the inventors hope to optimize and improve the existing rapid repair device for cracks in municipal roads. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and to provide a device and method for rapid repair of cracks in municipal roads.

[0009] Furthermore, in the aforementioned rapid repair device for municipal road cracks, the cutting mechanism includes a first grooved plate, a first vertical push rod, a rotary joint, a torque transmission shaft, a cutting bracket, a cutting blade, a cutting motor, a gearbox, a steering motor, a drive pulley, a transmission belt, and a driven torque transmission pulley. A drive push rod is installed between the second grooved plate and the left-side vertical support plate. The first vertical push rod is fixed to the inner wall of the upper side plate of the first grooved plate. The movable end of the first vertical push rod is connected to the upper end of the torque transmission shaft via a rotary joint. A cutting bracket is installed at the lower end of the torque transmission shaft. The lower end of the cutting bracket is movably supported by a rotating shaft. Two cutting blades are mounted side by side on the outer side of the rotating shaft. A cutting motor is fixed on the outer side of the cutting bracket.

A steering motor is fixed on the outer side of the web of the first grooved plate. A drive pulley is installed at the output end of the steering motor. The drive pulley is connected to a driven torque transmission pulley sleeved on the outer side of the torque transmission shaft via a transmission belt. The driven torque transmission pulley is movably supported by the lower side plate of the first grooved plate.

[0010] Furthermore, in the aforementioned rapid repair device for municipal road cracks, a torsion transmission groove is formed around the outer side of the torsion transmission shaft, and a torsion transmission protrusion is formed around the inner wall of the driven torsion transmission pulley. The torsion transmission protrusion is engaged in the corresponding torsion transmission groove.

[0011] Furthermore, in the aforementioned rapid repair device for municipal road cracks, the breaking mechanism includes a second vertical push rod, a mounting plate, and a breaking blade. The second vertical push rod is installed between two vertical support plates of the mounting frame, and the breaking blade is mounted on the movable end of the second vertical push rod via the mounting plate.

[0012] Furthermore, in the aforementioned rapid repair device for municipal road cracks, the filler filling mechanism includes a storage bin, which is located in the area between two horizontal connecting plates. The storage bin contains a melting chamber and a suction pump. A feeding pipe connected to the upper end of the melting chamber is installed at the top of the storage bin. The lower end of the melting chamber is connected to the suction end of the suction pump. The output end of the suction pump is connected to a filling head via a pumping pipe.

[0015] This invention also provides a method for rapid repair of cracks in municipal roads, based on the aforementioned rapid repair device for municipal road cracks, comprising the following steps: S1. Crack Location and Path Planning Visual recognition: Real-time images of road cracks are captured by cameras and transmitted to the controller and back-end terminal to generate a 3D model of the crack's direction and depth; Path planning: The controller automatically plans the movement path of the traveling mechanism based on the crack model, ensuring that the cutting, crushing, filling, and pressing mechanisms accurately cover the crack area; the traveling mechanism supports independent directional adjustment to adapt to curved cracks; S2. Crack Cutting and Cleaning Adaptive cutting: The steering motor drives the driven torsion pulley through the active pulley and transmission belt, which drives the torsion shaft to rotate and adjusts the direction of the cutting blade to match the inclination angle of the crack; the first vertical push rod presses down the torsion shaft and the cutting bracket, so that the cutting blade cuts into the edge of the crack to form a rectangular groove; Crushing and cleaning: The second vertical push rod presses down on the mounting plate, driving the crushing blade to perform secondary crushing on the loose fragments in the cut crack. Then the crushing blade moves along the rectangular groove to scrape away the crushed material, ensuring the groove is clean. S3, Filler Material Filling Material melting and conveying: The repair material in the storage silo is heated to a liquid state in the melting chamber, and the suction pump conveys the material to the filling head through the pumping pipe; Precise flow control: The suction pump adjusts its output according to the crack size; Embedded filling: The filling head is embedded in the pressure plate and moves synchronously with the pressure mechanism to inject molten material into the groove formed by the cutting; at the same time, the pressure plate compacts and levels the injected material to ensure that the filling is dense and without gaps.

[0016] The beneficial effects of this invention are: 1. Excellent Repair Results: Real-time images of road cracks are captured by cameras, generating a 3D model of the crack's direction and depth. The controller plans the movement path of the walking mechanism based on the model, ensuring that each mechanism accurately covers the crack area. First, the crack is cut to form a rectangular groove, then the debris is broken up and removed, and finally, filler material is poured in and compacted to ensure sufficient and dense filling, preventing re-cracking due to insufficient filling, resulting in a more ideal repair effect.

[0017] 2. High degree of automation: The controller connects various mechanisms, enabling automation of operations such as crack location, path planning, cutting, crushing, filling, and pressing, reducing manual intervention and improving repair efficiency. The controller connects to a back-end terminal via a wireless communication module. The back-end terminal displays camera footage and has control buttons for convenient remote monitoring and operation.

[0018] 3. High adaptability: The walking mechanism has an independently adjustable walking direction, which can adapt to curved cracks; the cutting mechanism can adjust the direction of the cutting blade to match the inclination angle of the crack, and can handle cracks with different directions and angles.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description
