Description

Technical Field

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

[0002] As highways age and traffic volume increases, road surfaces are prone to cracking. If these cracks are not addressed promptly, rainwater and debris will seep in, further exacerbating road damage, shortening the highway's lifespan, and affecting driving safety. Traditional methods of filling highway cracks often involve injecting filler using a crack injection gun and then smoothing it. However, in practice, the smoothing pressure cannot be adjusted by pressing the crack injection gun, resulting in incomplete filling.

[0003] Therefore, those skilled in the art have provided a highway crack filling device to solve the problems mentioned. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a highway crack filling device.

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

[0006] A highway crack filling device, comprising

[0007] The crack injection gun can be manually inserted into road cracks and moved to inject filler.

[0008] A connecting bracket is rotatably installed at the bottom outlet of the injection gun, with the lower surface of the connecting bracket higher than the bottom of the injection gun;

[0009] A flexible vertical rod is movably inserted into the rear end of the connecting frame in the direction of movement;

[0010] An inclined scraper is fixedly installed at the bottom of a vertical rod and is inclined downward in the opposite direction to the direction of movement of the injection gun, for scraping the filler.

[0011] A U-shaped frame is fixedly installed on the injection gun, with both ends of the U-shaped frame inclined downwards and in contact with the two sides of the vertical rod;

[0012] During the filling process, the two ends of the U-shaped frame and the two contact surfaces on the upper surface of the connecting frame are always located on both sides of the vertical rod.

[0013] Preferably, a spring is fitted on the vertical rod, and the spring is located at the bottom of the connecting frame. Under normal conditions, the scraper is located at the bottom of the stroke.

[0014] Preferably, when the scraper is at the top of its stroke, the top of the vertical rod contacts the injection gun.

[0015] Preferably, when the scraper is at the top of its stroke, the discharge port of the injection gun is higher than the bottom of the guide wheel and the scraper.

[0016] Preferably, a guide wheel for guiding along the crack is rotatably provided at the front end of the connecting frame in the direction of movement, and the bottom of the guide wheel is located between the bottom of the connecting frame and the bottom of the injection gun.

[0017] Preferably, the guide wheel is distributed along the axial direction with a thicker middle and thinner ends, the middle part of the guide wheel is cylindrical, and the two ends of the guide wheel are frustum-shaped.

[0018] In summary, this utility model has the following beneficial technical effects:

[0019] To address the inconvenience of adjusting the scraping force by pressing the injection gun, this utility model ensures that both ends of the U-shaped frame are always in the optimal position for compressing the springs, i.e., the optimal position for compressing the scraper. By pressing down the injection gun, the scraper achieves a better scraping effect and higher compression efficiency. When the discharge port of the injection gun tilts upward and is about to move away from the crack, the compression effect of the U-shaped frame reaches its maximum, and the finishing work of crack filling can be completed well.

[0025] 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.

[0026] A highway crack filling device, as shown in the reference Figure 1-3 It mainly includes components such as injection gun 1, connecting frame 2, U-shaped frame 3, vertical rod 4, scraper 5, spring 6 and guide wheel 7.

[0027] The injection gun 1, as the output component of the filler, is designed to be easy for the operator to hold and can be flexibly inserted into the road crack and moved along the crack, continuously injecting filler during the movement to fill the crack gaps.

[0028] The connecting frame 2 is rotatably installed at the bottom outlet of the injection gun 1. The lower surface of the connecting frame 2 is higher than the bottom of the injection gun 1. This structural design ensures the relative flexibility of the connecting frame 2 without hindering the material output of the injection gun 1.

[0029] A guide wheel 7 is rotatably provided at the front end of the connecting frame 2 in the direction of movement to guide along the crack. The bottom of the guide wheel 7 is located between the bottom of the connecting frame 2 and the bottom of the injection gun 1. The guide wheel 7 plays a guiding role, which enables the entire device to move smoothly along the road crack, reduces the difficulty of judging the direction of the crack during manual operation, and improves the accuracy of the filling operation.

[0030] The guide wheel 7 is thicker in the middle and thinner at both ends along the axial direction. The middle part of the guide wheel 7 is cylindrical, and the two ends are frustum-shaped. This special shape design allows the guide wheel 7 to adapt well to cracks of different widths. The cylindrical part in the middle ensures stable guidance under normal crack width, while the frustum-shaped parts at both ends can smoothly transition when the crack width changes slightly, without getting stuck due to uneven crack width. This further improves the adaptability of the device to crack filling in complex road conditions.

[0031] The vertical rod 4 is movably inserted into the rear end of the connecting frame 2 in the direction of movement. Specifically, a spring 6 is sleeved on the vertical rod 4. The spring 6 is located at the bottom of the connecting frame 2. Under normal conditions, the scraper 5 is located at the bottom of the stroke.

[0032] The inclined scraper 5 is fixedly installed at the bottom of the vertical rod 4, and the scraper 5 is inclined downward in the opposite direction to the moving direction of the injection gun 1. In this way, the scraper 5 can evenly scrape the filler injected into the crack by the injection gun 1 during the movement of the device, so that it can fit tightly with the road surface, improve the filling quality, and reduce the potential for subsequent road surface defects.

[0033] The U-shaped frame 3, fixedly mounted on the injection gun 1, has its two ends tilted downwards, and both ends of the U-shaped frame 3 are in contact with the sides of the vertical rod 4. During the filling process, the two contact surfaces between the two ends of the U-shaped frame 3 and the upper surface of the connecting frame 2 are always located on both sides of the vertical rod 4. The U-shaped frame 3 serves to limit and stabilize the vertical rod 4, preventing it from shaking or shifting excessively during operation, ensuring that the scraper 5 is always in a suitable leveling position, and further ensuring the stability and reliability of the filling operation.

[0034] In actual operation, both ends of the U-shaped frame 3 are always in the optimal position of the compression spring 6, that is, the optimal position of the compression scraper 5. By pressing down the injection gun 1, the scraper 5 can achieve a better leveling effect and higher compression efficiency. When the discharge port of the injection gun 1 is tilted upward and about to move away from the crack, the compression effect of the U-shaped frame 3 reaches its maximum, and the finishing work of filling a crack is most perfect.

[0035] When the discharge port of the injection gun 1 is tilted upwards and about to move away from the crack, and the scraper 5 is at the top of its stroke, the top of the vertical rod 4 contacts the injection gun 1, which can stabilize the structure and improve the leveling effect. The discharge port of the injection gun 1 is higher than the bottom of the guide wheel 7 and the scraper 5, so the road surface crack will not affect the discharge port of the injection gun 1, making it convenient for the discharge port to move out while the scraper 5 is leveling.

[0036] 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.
