Description

Technical Field

[0001] This utility model relates to the technical field of crack sealing equipment for road surface repair, specifically a crack sealing device for road surface repair. Background Technology

[0002] With the rapid development of modern transportation construction, road surfaces are prone to cracks due to factors such as vehicle load and climate. Crack sealing equipment has become a key tool for road repair. It efficiently fills cracks by precisely heating and injecting sealing materials, preventing moisture from seeping into and damaging the roadbed, extending the road's lifespan, and is suitable for various scenarios such as high-grade highways and municipal roads. It is an important piece of equipment to ensure smooth traffic.

[0003] Existing road surface repair crack sealing equipment includes a crack sealing cylinder. Workers hold the cylinder and position its end against the road crack. As the cylinder moves along the crack, asphalt flows into the crack, repairing it. However, for large road surfaces requiring repair, this requires prolonged work with the cylinder held in hand. After sealing, workers then use tools to scrape the asphalt out of the crack, resulting in high workload for the workers. To address these shortcomings, this invention provides a road surface repair crack sealing device to solve the aforementioned problems. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a crack sealing device for road surface repair, according to the attached... Figure 1 As shown, it includes:

[0025] The main body 1 of the injection cylinder is used to store sealant or asphalt material and to achieve precise grouting through the bottom injection nozzle 9. Its interior can be designed with a double-layer structure, with an outer insulation layer and an inner heat-conducting layer to ensure that the material maintains its fluidity during transportation;

[0026] The injection nozzle 9 is located at the bottom of the injection cylinder body 1. The injection nozzle 9 can evenly spray the sealant inside the injection cylinder body 1 into the road surface cracks. The internal design of the injection nozzle 9 features a spiral guide groove, causing the material to be sprayed out in a spiral shape, enhancing the filling density. An electric heating wire is wrapped around the outside of the nozzle to prevent the material from condensing before spraying.

[0027] A connecting pipe 2 is fixedly connected to the upper end of the injection cylinder body 1. The connecting pipe 2 is used to connect to an external material supply system to realize the continuous delivery of sealant. A push handle 3 is fixedly connected to the injection cylinder body 1. The push handle 3 provides the operator with a point of force to control the direction and speed of the equipment movement.

[0028] According to the appendix Figure 2 As shown, further, the U-shaped scraper 10 is set at the bottom of the injection cylinder body 1. The U-shaped scraper 10 can scrape the asphalt injected into the crack to form a flat sealing layer, ensuring that there is no protruding asphalt on both sides of the crack, and reducing the number of steps in the injection process.

[0029] The mounting mechanism 11 includes a fixed extension plate 1101 fixedly connected to the outer peripheral wall of the injection cylinder body 1, and a mounting plate 1102 fixedly connected to the bottom of the fixed extension plate 1101. The mounting mechanism 11 is used to install the U-shaped scraper 10. The U-shaped scraper 10 can be detached from the mounting mechanism 11, so that it can be quickly replaced after the U-shaped scraper 10 has been used for a long time.

[0030] The directional wheel 8 is located at the bottom of the injection cylinder body 1, supporting the weight of the equipment and guiding the direction of movement, ensuring that the equipment travels in a straight line along the crack during the crack filling process. Together with the U-shaped scraper 10 on the installation mechanism 11, it can provide good support for the injection cylinder body 1 during crack filling, and can reduce the workload of workers when repairing large road surfaces.

[0031] A connecting plate 4 is fixedly connected to the main body 1 of the injection cylinder. The connecting plate 4 is used to install the alignment block 5 and the L-shaped mounting part 6. The alignment block 5 is fixedly connected to the connecting plate 4. The alignment block 5 is located directly above the injection nozzle 9. The alignment block 5 serves as a visual reference point to help the operator align the injection nozzle 9 with the center of the crack and improve the injection accuracy.

[0032] An L-shaped mounting piece 6 is fixedly connected to the bottom of the connecting plate 4. A rotating shaft 7 is rotatably connected inside the L-shaped mounting piece 6. The L-shaped mounting piece 6 and the rotating shaft 7 are used to fix the directional wheel 8 and allow it to rotate, so as to support the main body 1 of the injection cylinder and drive it to flexibly turn. The directional wheel 8 is fixedly connected to both ends of the rotating shaft 7.

[0033] A locking bolt 1001 is fixedly connected to the U-shaped scraper 10. A fixing pin 12 is installed between the locking bolt 1001 and the mounting plate 1102. The fixing pin 12 is made of spring steel and automatically locks after insertion to prevent it from falling off. This facilitates the quick assembly and disassembly of the U-shaped scraper 10 and the mounting plate 1102, and makes it easy to replace or clean the scraper.

[0034] The locking bolt 1001 and the U-shaped scraper 10 are integrally formed, and the fixed extension plate 1101 and the mounting plate 1102 are integrally formed.

[0035] Working principle: First, connect the main body 1 of the injection cylinder to the outlet of the hot melt kettle through the connecting pipe 2, and ensure that there is no leakage. Then, align the locking bolt 1001 of the U-shaped scraper 10 with the locking bolt 1001 hole of the mounting plate 1102, fix it with the fixing pin 12, and adjust the laser beam of the alignment block 5 to align it with the center of the injection nozzle 9. Start the hot melt kettle, heat the sealant to 120°C and deliver it to the main body 1 of the injection cylinder. The operator holds the push handle 3 and pushes the equipment to the crack initiation position so that the directional wheel 8 is aligned with the crack edge.

[0036] Turn on the injection nozzle 9 and slowly push the equipment to fill the crack with sealant evenly. Align the laser beam on block 5 to display the nozzle position in real time. The operator adjusts the movement direction according to the laser. The U-shaped scraper 10 moves with the equipment and automatically scrapes off excess material at the crack opening. After the operation is completed, turn off the injection nozzle 9 and pull out the fixing pin 12. Disassemble the U-shaped scraper 10 for cleaning.

[0037] The road surface repair and crack filling equipment adopts a structure in which the installation mechanism 11 is fixedly connected to the main body 1 of the filling cylinder. With the help of the directional wheel 8, it can effectively support the main body 1 of the filling cylinder during crack filling. When repairing a large road surface area, it can reduce the workload of the workers. The U-shaped scraper 10 can scrape the asphalt injected into the crack to ensure that there is no protruding asphalt on both sides of the crack, reducing the number of crack filling steps. The installation mechanism 11 can disassemble and install the U-shaped scraper 10, which is convenient to replace after long-term use.
