Description

Technical Field

[0001] This utility model relates to the field of highway maintenance technology, specifically a highway pavement maintenance device. Background Technology

[0002] Highway pavements are prone to developing cracks of varying degrees under long-term vehicle loads, environmental temperature and humidity changes, and natural erosion. If these cracks are not maintained in a timely manner, rainwater and debris will seep into them, eroding the roadbed, exacerbating pavement damage, and affecting traffic safety and the road's lifespan. Currently, small crack sealing equipment (such as hand-push crack sealing machines) is widely used in highway pavement crack repair operations due to its flexible operation and suitability for small-scale crack maintenance scenarios. Its core principle is to heat and melt asphalt sealant, then inject it into the crack and scrape it to achieve sealing and protection.

[0003] However, the existing small crack sealing equipment has shortcomings in its injection method. During the injection process, the asphalt repair material mainly relies on its own fluidity and gravity to fill the cracks. However, highway cracks often have irregular uneven structures. Such structures are prone to forming flow blind zones, making it difficult for the asphalt repair material to fully penetrate and fill these areas. As a result, air is easily trapped inside the crack, forming hollow defects. This leads to insufficient filling density of the asphalt repair material, affecting maintenance durability. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a highway pavement maintenance device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A road surface maintenance device includes a hopper with a guide plate at its bottom, and the upper surface of the guide plate extends obliquely to the discharge port of the hopper to form a flow guide surface for filling the sealing material in the hopper.

[0007] The insert is threaded to the back of the guide plate, and its bottom end extends downward at an angle and slides through the injection guide surface;

[0008] The trolley is fixedly connected to the hopper;

[0009] When the user pushes the trolley to inject the material into the road crack, the bottom end of the pin extends into the crack and vibrates under the control of the trolley's movement, so that the repair material flowing around the pin is compacted after vibration.

[0010] Preferably, the direction of the infusion guide surface and the direction of the extension of the insertion pin are both opposite to the direction of movement of the trolley.

[0011] Preferably, the upper surface of the guide plate has a groove along its extension direction, and the two sides of the upper surface of the guide plate are affected by the groove to form a side barrier.

[0012] Preferably, the cross-section of the groove is V-shaped or concave arc-shaped.

[0013] Preferably, the width of the guide plate gradually narrows along its extension direction so that its bottom end is approximately pointed, which facilitates the filling of material into the crack.

[0014] Preferably, the trolley is provided with a handle, and the bottom end of the handle is provided with a V-shaped scraper. The V-shaped scraper is configured such that when the user pushes the trolley to move, the V-shaped scraper can be flush with the road surface to scrape the repair material.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: through the coordinated operation of the guide plate and the needle, the repair material entering the crack can be vibrated and compacted, effectively solving the problems of hollowness and insufficient density caused by gravity injection in existing small crack filling equipment, and enhancing the adhesion between the repair material and the crack; in addition, the configuration of the trolley and V-shaped scraper improves the work efficiency and road surface smoothness, extends the road surface maintenance durability, and is suitable for rapid maintenance of small-scale highway cracks.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Example

[0024] like Figures 1-4 As shown, a road surface maintenance device includes a hopper 1, which serves as a container for repair material and provides a storage space for raw materials for grouting operations. A guide plate 11 is provided at the bottom of the hopper 1, and the upper surface of the guide plate 11 extends obliquely to the discharge port of the hopper 1 to form a grouting guide surface for the sealant in the hopper 1. The oblique guide surface can guide the repair material in the hopper 1 to flow stably toward the road surface cracks by gravity.

[0025] The upper surface of the guide plate 11 has grooves along its extension direction, and the two sides of the upper surface of the guide plate 11 are affected by the grooves to form side barriers. The side barriers formed by the grooves can limit the flow range of the repair material, prevent the repair material from overflowing to both sides during the grouting process, and improve the grouting accuracy. The cross-section of the groove is V-shaped or concave arc-shaped. The V-shaped or concave arc-shaped grooves can optimize the flow path of the repair material, reduce the flow resistance, and at the same time make it have the effect of converging towards the center during the flow process, so that it can flow into the cracks in the road surface.

[0026] The width of the guide plate 11 gradually narrows along its extension direction so that its bottom end is approximately pointed. The narrowed pointed bottom end can be accurately aligned with the road surface cracks, so that the repair material can be accurately injected into the cracks and the waste of sealant can be avoided.

[0027] The insertion pin 12 is threaded to the back of the guide plate 11, and its bottom end extends downward at an angle and slides through the injection guide surface; the insertion length of the insertion pin 12 can be adjusted by means of threaded connection to flexibly adapt to cracks of different depths.

[0028] The trolley 2 is fixedly connected to the hopper 1, providing a mobile carrier for the device, making it convenient for operators to push the equipment along the crack for operation. At the same time, the trolley 2 will generate vibrations that are transmitted to the whole device during the movement of the trolley on the road surface.

[0029] When the user pushes the trolley 2 to drive the hopper 1 to fill the road cracks, the bottom end of the needle 12 extends into the crack and vibrates under the control of the trolley 2. This vibration compacts the repair material flowing around the needle 12. The vibration breaks the air-encapsulated state formed by gravity filling inside the repair material, promotes air expulsion, avoids the formation of hollows in the deep cracks, and significantly improves the filling density of the repair material. At the same time, the vibration can push the repair material to better penetrate into the uneven parts of the crack, enhance the adhesion between the repair material and the crack wall, lay the foundation for improving the bonding effect in the future, and effectively solve the defect of poor compaction of existing equipment.

[0030] The direction of the injection guide surface and the extension direction of the pin 12 are both opposite to the moving direction of the trolley 2. This design allows the user to easily observe the filling status of the repair material during the injection process. At the same time, at this angle, the pin 12 can increase the contact area with the repair material, further improving the injection effect of the repair material.

[0031] The trolley 2 is equipped with a handle 3, and a V-shaped scraper 31 is provided at the bottom of the handle 3. The V-shaped scraper 31 is configured such that when the user pushes the trolley 2 to move, the V-shaped scraper 31 can be flush with the road surface to scrape the repair material. The V-shaped scraper 31 can quickly scrape off the excess repair material on the road surface, making the repaired road surface flat, avoiding the accumulation of excess material that affects vehicle passage, and ensuring that the repair material is evenly covered at the crack opening, further improving the sealing and protection effect.

[0032] In summary, this highway pavement maintenance device optimizes the maintenance effect of road cracks from multiple dimensions, including injection accuracy, filling density, ease of operation, and repair smoothness, through the synergistic effect of its components. On the one hand, the structural design of the guide plate 11 combined with the vibration function of the pin 12 effectively solves the problems of hollow areas and insufficient density caused by gravity injection in existing small crack filling equipment, and enhances the adhesion between the repair material and the crack. On the other hand, the configuration of the trolley 2 and the V-shaped scraper 31 improves the work efficiency and pavement smoothness, extends the pavement maintenance durability, and is suitable for rapid maintenance of small-scale highway cracks.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
