Description

Technical Field

[0001] The utility model relates to the technical field of highway maintenance equipment, in particular to a crack filling device for highway maintenance. Background Art

[0002] Highway cracks need to be filled to ensure driving safety and prevent cracks from expanding and causing further damage to the road surface. At the same time, it reduces the intrusion of moisture and impurities, maintains the flatness and stability of the road surface, thereby extending the service life of the highway, reducing maintenance costs, and improving driving comfort.

[0003] At present, a Chinese patent discloses a highway crack filling device (publication number CN220847008U). The highway crack filling device is configured by installing a first mounting rod, a nut and a seam pressing plate, wherein the first mounting rod is installed inside a mounting groove, and the seam pressing plate is inserted into the gap. When a caulking gun is moved forward, the caulking gun can move straight forward because the seam pressing plate is limited in the gap, so that the caulking gun can caulk the crack straightly, making the asphalt trace straight and more beautiful.

[0004] Since the seam pressing plate in the above-mentioned device is rotatably connected to the inner side of the mounting groove and the seam pressing plate is round, and the asphalt itself is very viscous, some asphalt will inevitably adhere to its surface during the process of rotating and squeezing the asphalt. This will make the surface of the seam pressing plate no longer clean, resulting in uneven subsequent pressing seams and poor aesthetics.

[0005] Therefore, a crack filling device for highway maintenance is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a crack filling device for highway maintenance in order to solve the above-mentioned problem, thereby improving the problem that the existing crack filling device for highway maintenance is difficult to ensure smooth press seams and has poor aesthetics.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, a crack filling device for road maintenance, comprising: a caulking gun, the surface of which is rotatably connected to a scraper, and the surface of which is rotatably connected to a crack pressing wheel; a cleaning device, which is fixedly connected to the top of the scraper, and the bottom of the cleaning device is in contact with the crack pressing wheel.

[0008] Preferably, the cleaning device includes an arch frame fixedly connected to the top of the scraper frame, the inner side of the arch frame is slidably connected with a scraper in contact with the seam pressing wheel, the top of the scraper is installed with an adjustment mechanism, the top of the adjustment mechanism passes through the outside of the arch frame, during the rotation of the seam pressing wheel, the scraper pushes and scrapes away the asphalt and impurities adhered to the surface of the seam pressing wheel, so that the surface of the seam pressing wheel is cleaner, thereby ensuring the flatness of the asphalt rolled by the seam pressing wheel.

[0009] Preferably, the numerical cross-sectional shape of the scraper is an inverted V shape, and both ends of the scraper are in contact with the press wheel. The scraper with an inverted V-shaped design can effectively scrape off impurities adhered to the surface of the press wheel regardless of whether the press wheel moves forward or backward, thereby further improving the cleanliness of the surface of the press wheel.

[0010] Preferably, the adjustment mechanism includes a threaded column threadedly connected to the top of the arch frame, and the bottom of the threaded column passes through the arch frame and is rotatably connected to the scraper. The staff can adjust the height of the scraper by rotating the threaded column, which can not only adjust the pressure between the scraper and the seam pressing wheel, but also enable the staff to install seam pressing wheels of different specifications to meet different seam pressing requirements.

[0011] Preferably, an adjustment handle is fixedly connected to the top of the threaded column, and the horizontal cross-sectional shape of the adjustment handle is a cross, which enables the staff to rotate the threaded column more easily and stably, thereby reducing the difficulty of adjustment for the staff.

[0012] Preferably, the surface of the threaded column is covered with two protective covers, the top of the upper protective cover is rotatably connected to the adjusting handle, the bottom of the upper protective cover is fixedly connected to the arch frame, and the top and bottom ends of the lower protective cover are respectively fixedly connected to the arch frame and the scraper. Under the premise of not affecting the normal lifting and lowering of the threaded column, the two protective covers can cover the part of the threaded column exposed outside the arch frame and the connection between the threaded column and the arch frame, so as to prevent external impurities from adhering to the surface of the threaded column, so that the threaded column is always operated in a clean environment, thereby ensuring that the threaded column can be lifted and lowered normally.

[0013] Preferably, the vertical cross-section of the protective cover is wavy, and the protective cover is a rubber material component, which enables elastic deformation of the protective cover and reduces the damage rate of the protective cover during the telescopic deformation process.

[0014] Preferably, two slide grooves are opened on the inner side of the arch frame, and a slider fixedly connected to the scraper is slidably connected inside the slide groove. The slide groove can prevent the scraper from rotating during the lifting process through the slider to ensure that the scraper can run horizontally.

[0015] Preferably, the inner side of the slider is rotatably connected to a roller in contact with the slide groove, which can reduce the sliding resistance of the slider on the inner side of the slide groove, so that the scraper can be lifted and lowered more smoothly.

[0016] The beneficial effects of the utility model are:

[0017] 1. During the rotation of the press wheel, the scraper pushes and scrapes off the asphalt and impurities adhering to the surface of the press wheel, making the surface of the press wheel cleaner, thereby ensuring the flatness of the asphalt rolling by the press wheel. In addition, the scraper adopts an inverted V-shaped design. Whether the press wheel moves forward or backward, the scraper can effectively scrape off the impurities adhering to the surface of the press wheel, further improving the cleanliness of the surface of the press wheel;

[0018] 2. The staff can adjust the height of the scraper by rotating the threaded column, which can not only adjust the pressure between the scraper and the seam pressing wheel, but also enable the staff to install seam pressing wheels of different specifications to meet different seam pressing requirements.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-4 As shown, a crack filling device for highway maintenance includes: a caulking gun 1, the surface of which is rotatably connected to a scraper frame 2, and the surface of which is rotatably connected to a crack pressing wheel 3; a cleaning device 4, which is fixedly connected to the top of the scraper frame 2, and the bottom of the cleaning device 4 is in contact with the crack pressing wheel 3.

[0026] like Figure 3 and Figure 4As shown, the cleaning device 4 includes an arch frame 41 fixedly connected to the top of the scraper frame 2, and a scraper 42 in contact with the seam pressing wheel 3 is slidably connected to the inner side of the arch frame 41. An adjusting mechanism 43 is installed on the top of the scraper 42, and the top of the adjusting mechanism 43 passes through the outside of the arch frame 41; the numerical cross-sectional shape of the scraper 42 is an inverted V shape, and both ends of the scraper 42 are in contact with the seam pressing wheel 3.

[0027] like Figure 3 and Figure 4 As shown, the adjustment mechanism 43 includes a threaded column 431 threadedly connected to the top of the arch frame 41, the bottom of the threaded column 431 penetrates the arch frame 41 and is rotatably connected to the scraper 42; the top of the threaded column 431 is fixedly connected to an adjustment handle 432, and the horizontal cross-sectional shape of the adjustment handle 432 is a cross; the surface of the threaded column 431 is sleeved with two protective sleeves 433, the top of the upper protective sleeve 433 is rotatably connected to the adjustment handle 432, the bottom of the upper protective sleeve 433 is fixedly connected to the arch frame 41, and the top and bottom ends of the lower protective sleeve 433 are respectively fixedly connected to the arch frame 41 and the scraper 42; the vertical cross-sectional shape of the protective sleeve 433 is wavy, and the protective sleeve 433 is a rubber material component; the inner side of the arch frame 41 is provided with two slide grooves 411, and the inside of the slide groove 411 is slidably connected to a slider 44 fixedly connected to the scraper 42; the inner side of the slider 44 is rotatably connected to a roller 45 in contact with the slide groove 411;

[0028] When the staff needs to adjust the height of the scraper 42, the staff only needs to rotate the adjusting handle 432 in the corresponding direction. The adjusting handle 432 drives the threaded column 431 to rotate. The threaded column 431 rises and falls along the arch frame 41. The threaded column 431 drives the scraper 42 to rise and fall. This can not only adjust the pressure between the scraper 42 and the seam pressing wheel 3, but also enable the staff to install seam pressing wheels 3 of different specifications to meet different seam pressing requirements.

[0029] When the utility model is in use, when the staff holds the caulking gun 1 and moves to fill the road gap, the caulking gun 1 drives the scraper 2 to move, and the scraper 2 drives the pressing wheel 3 to rotate and roll the asphalt in the gap, making the asphalt smoother. During the rotation of the pressing wheel 3, the scraper 42 pushes and scrapes away the asphalt and impurities adhered to the surface of the pressing wheel 3, making the surface of the pressing wheel 3 cleaner, thereby ensuring the smoothness of the asphalt rolled by the pressing wheel 3. In addition, the scraper 42 with an inverted V-shaped design is adopted. Regardless of whether the pressing wheel 3 moves forward or backward, the scraper 42 can effectively scrape away the impurities adhered to the surface of the pressing wheel 3, further improving the cleanliness of the surface of the pressing wheel 3.

[0030] It should be noted that the caulking gun 1 in the above description is a device with relatively mature application of existing technology. The specific model can be selected according to actual needs. At the same time, the caulking gun 1 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.
