Description

Technical Field

[0001] This utility model belongs to the field of ground crack filling technology, and specifically relates to a ground crack filling device. Background Technology

[0002] Over a long period of use, road surfaces are prone to cracking. The impact of passing vehicles can cause these cracks to widen, leading to localized road surface breakage. In such cases, road surface crack repair is necessary.

[0003] In the current technological field, traditional ground crack repair equipment typically requires heating repair materials such as asphalt to a molten state before pouring them into the cracks, either manually or mechanically. The molten material is then compacted by repeated rolling of rollers to ensure a tight bond between the repair material and the crack edges. However, this method has several drawbacks: it requires operators to continuously push the equipment to ensure the rollers fully compact the repair material. This not only increases the labor intensity for workers but also reduces operational efficiency.

[0004] To address the aforementioned problems, this application proposes a ground crack filling device. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a ground crack filling device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ground crack filling device, comprising a filling frame, wherein the filling frame consists of a support, multiple wheels and a handle disposed on the support;

[0007] The support is equipped with a filling component for filling cracks and a compaction component for compacting the filled cracks.

[0008] The filling component includes a U-shaped fixing plate fixed on a bracket, an asphalt bucket fixed on the U-shaped fixing plate, and a discharge pipe connected to the asphalt bucket.

[0009] Preferably, the compaction assembly includes two pressure rollers disposed below the support and a movable plate slidably disposed on the support. A connector is fixed on the movable plate, and a first inclined frame and a second inclined frame are rotatably connected to the connector. The two pressure rollers are respectively rotatably disposed at the ends of the first inclined frame and the second inclined frame.

[0010] The compaction assembly also includes four sets of drive components mounted on the support for driving the moving plate to slide.

[0011] Preferably, the drive assembly includes a cam rotatably connected to a bracket via a rotating shaft. A pair of mounting plates are fixed to the bracket, and a slide rod is slidably connected to the pair of mounting plates. One end of the slide rod is fixedly connected to the moving plate, and the other end of the slide rod abuts against the cam. A fixing plate is fixed to the outer wall of the slide rod, and a return spring is also sleeved on the outer wall of the slide rod. One end of the return spring abuts against the bottom of the fixing plate, and the other end of the return spring abuts against the top of the mounting plate. A motor for driving the cam to rotate is also fixed to the bracket.

[0012] Preferably, a fixing rod is fixed on the first tilting frame.

[0013] Preferably, the pressure roller is provided with a counterweight.

[0014] Preferably, the width of the U-shaped fixed plate is smaller than the width of the movable plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the rotational motion of the cam is converted into the sliding motion of the moving plate, thereby driving the pressure roller to effectively compact the asphalt in the crack. This process not only improves the efficiency of compaction operations but also reduces reliance on manual labor, significantly reducing the labor intensity of workers. In addition, the moving plate can automatically reset after the cam has finished rotating, ensuring that the pressure roller can operate continuously, thereby further enhancing the practicality and efficiency of the device. At the same time, the use of a motor to drive the cam rotation makes the compaction operation more stable and effectively avoids problems such as uneven compaction caused by human error.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The present invention provides the following technical solution: a ground crack filling device, including a filling frame, which consists of a support 1, multiple wheels 2 and a handle 18 disposed on the support 1;

[0027] The support 1 is equipped with a filling component for filling cracks and a compaction component for compacting the filled cracks;

[0028] The filling component includes a U-shaped fixing plate 3 fixed on the support 1, an asphalt bucket 4 fixed on the U-shaped fixing plate 3, and an asphalt bucket 4 connected to a discharge pipe 5. The compaction component includes two pressure rollers 16 set below the support 1 and a movable plate 12 slidably set on the support 1. A connector 13 is fixed on the movable plate 12, and a first inclined frame 14 and a second inclined frame 15 are rotatably connected to the connector 13. The two pressure rollers 16 are respectively rotatably set at the ends of the first inclined frame 14 and the second inclined frame 15.

[0029] The compaction assembly also includes four sets of drive components mounted on the support 1 to drive the moving plate 12 to slide. In use, firstly, molten asphalt can be placed in the asphalt bucket 4, and the device can be moved by pushing the handle 18, so that the wheels 2 roll on the ground, thereby driving the device to move. When it is necessary to fill the ground cracks, the discharge pipe 5 is opened, and asphalt flows into the cracks through the discharge pipe 5 to fill the cracks. After the filling is completed, the support 1 can be moved again by the wheels 2, and the compaction assembly on the support 1 can be moved above the cracks. Then, the drive components are used to drive the moving plate 12 to slide.

[0030] When the movable plate 12 slides downward, the movable plate 12 will drive the connecting piece 13 to move downward together. The connecting piece 13 will then drive the first tilting frame 14 and the second tilting frame 15 to rotate around the connection point within a certain range, thereby driving the two pressure rollers 16 to move until the pressure rollers 16 contact the ground above the crack and apply downward pressure. The pressure rollers 16 can then be used to compact the ground above the crack to ensure that the asphalt filled in the crack is tightly bonded to the ground at the edge of the crack, thus improving the repair effect.

[0031] When the movable plate 12 slides upward, the first tilting frame 14 and the second tilting frame 15 will rotate in the opposite direction around the connection point under the elastic force of the return spring 10, thereby driving the two pressure rollers 16 to move, so that the two pressure rollers 16 press the ground again until the movable plate 12 returns to its initial position (e.g., Figure 2 Then, the movable support 1 can be moved, and the above filling and compaction process can be repeated until the repair work of the entire crack is completed.

[0032] Specifically, by Figure 1 , Figure 3 and Figure 5As shown, in this embodiment, the driving assembly includes a cam 6 rotatably connected to a bracket 1 via a rotating shaft. A pair of mounting plates 7 are fixed on the bracket 1, and a slide rod 8 is slidably connected to the pair of mounting plates 7. One end of the slide rod 8 is fixedly connected to a moving plate 12, and the other end of the slide rod 8 abuts against the cam 6. A fixing plate 9 is fixed to the outer wall of the slide rod 8, and a return spring 10 is also sleeved on the outer wall of the slide rod 8. One end of the return spring 10 abuts against the bottom of the fixing plate 9, and the other end of the return spring 10 abuts against the top of the mounting plate 7. An electric motor for driving the cam 6 to rotate is also fixed on the bracket 1. Machine 20; by setting cam 6, when cam 6 rotates, it can drive slide rod 8 to slide on mounting plate 7, thereby achieving the purpose of driving moving plate 12 to slide, and the driving method is simple and convenient; by setting motor 20, when motor 20 works, it can drive cam 6 to rotate, and under the action of return spring 10, it can reset moving plate 12, so that under the rotation of cam 6, moving plate 12 can slide back and forth, thereby driving first tilting frame 14 and second tilting frame 15 to rotate back and forth, so that pressure roller 16 can repeatedly compact the asphalt in the crack, saving manpower.

[0033] Specifically, by Figure 2 and Figure 4 As shown in this embodiment, a fixing rod 17 is fixed on the first tilting frame 14; by setting the fixing rod 17, one end of the fixing rod 17 can abut against the second tilting frame 15, so as to avoid the first tilting frame 14 and the second tilting frame 15 from being in contact with each other, thereby ensuring that the two pressure rollers 16 can maintain an appropriate distance.

[0034] Specifically, by Figure 2 As shown in this embodiment, the pressure roller 16 is provided with a counterweight; this can increase the weight of the pressure roller 16, so that the pressure roller 16 can achieve a better compaction effect when compacting the asphalt in the crack.

[0035] Specifically, by Figure 1 As shown, in this embodiment, the width of the U-shaped fixed plate 3 is smaller than the width of the movable plate 12 to prevent the movable plate 12 from interfering with the U-shaped fixed plate 3 during the sliding process.

[0036] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0037] Components not described in detail in this article are existing technologies.

[0038] The working principle and usage process of this utility model are as follows: When in use, firstly, molten asphalt can be placed in the asphalt bucket 4. The device is moved by pushing the handle 18, so that the wheel 2 rolls on the ground, thereby moving the device. When it is necessary to fill the ground crack, the discharge pipe 5 is opened, and the asphalt flows into the crack through the discharge pipe 5 to fill the crack. After the filling is completed, the support 1 can be moved again by the wheel 2, and the compaction component on the support 1 is moved to the top of the crack.

[0039] By setting cam 6, when cam 6 rotates, it can drive slide rod 8 to slide on mounting plate 7, thereby achieving the purpose of driving moving plate 12 to slide. The driving method is simple and convenient. By setting motor 20, when motor 20 works, it can drive cam 6 to rotate. Under the action of return spring 10, it can reset moving plate 12 so that moving plate 12 can slide back and forth under the rotation of cam 6, thereby driving the first tilting frame 14 and the second tilting frame 15 to rotate back and forth, so that pressure roller 16 can repeatedly compact the asphalt in the crack, saving manpower.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
