A highway pavement crack processing device

Abstract

This utility model discloses a device for treating road surface cracks, relating to the field of crack treatment technology. It includes a fixed cylinder; a liquid storage tank located above the fixed cylinder and fixedly connected to it; a liquid outlet located at the bottom of the fixed cylinder for discharging liquid from within the fixed cylinder; a rotating shaft passing through the fixed cylinder along its central axis and rotatably engaging with it; and at least three fixed plates, all uniformly fixed in a ring around the rotating shaft, with the end of each fixed plate away from the rotating shaft slidingly engaged with the inner wall of the fixed cylinder. This utility model, by setting uniformly distributed ring-shaped fixed plates within the fixed cylinder to engage with the rotating shaft, allows liquid from the storage tank to fall into the cavity formed by two fixed plates.

Description

Technical Field

[0001] This utility model relates to the field of crack treatment technology, specifically a device for treating cracks in highway pavement. Background Technology

[0002] During long-term use, highways are prone to developing cracks of varying degrees due to factors such as vehicle loads, temperature changes, and geological subsidence. If these cracks are not treated promptly, rainwater and debris can seep into the base layer, exacerbating road surface damage and shortening the highway's lifespan.

[0003] Currently, the treatment of road surface cracks mostly adopts manual crack filling, which involves injecting crack filling material into the cracks with hand tools and then scraping it smooth. However, the existing technology has obvious shortcomings: First, the distribution of crack filling material is difficult to control, and uneven distribution, material breakage, or excessive overflow are prone to occur, resulting in material waste and unstable filling quality; Second, most dispensing devices rely on electricity or additional mechanical power, which increases equipment costs and operational complexity, and limits applicability in situations without power or in complex road conditions; Third, there is a lack of an effective synchronous scraping structure after material injection, resulting in low efficiency of manual scraping and difficulty in ensuring uniform material distribution and smoothness on the crack surface, affecting the durability and aesthetics of the repaired road surface; Fourth, some devices are inconvenient to move and have poor stability during operation, increasing the labor intensity of manual workers. Utility Model Content

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

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

[0006] A highway pavement crack treatment device, comprising:

[0007] Fixed cylinder;

[0008] The storage tank is located above the fixed cylinder and is fixedly connected to the fixed cylinder;

[0009] The liquid outlet is located at the bottom of the fixed cylinder and is used for discharging the liquid inside the fixed cylinder.

[0010] The rotating shaft passes through the fixed cylinder along the central axis of the fixed cylinder and rotates in conjunction with the fixed cylinder.

[0011] At least three fixing plates are provided, and all fixing plates are uniformly fixed in a ring around the circumference of the rotating shaft. The end of the fixing plate away from the rotating shaft slides against the inner wall of the fixing cylinder.

[0012] A turntable is set on the same central axis as the rotating shaft and fixed at both ends of the rotating shaft, and the diameter of the turntable is larger than the diameter of the rotating shaft;

[0013] in:

[0014] When continuous feeding is required, the liquid in the storage tank falls into the cavity formed by the two fixed plates above. The center of gravity of the liquid in the cavity shifts, causing the shaft to rotate continuously, ensuring the continuous falling of the liquid.

[0015] Preferably, a connecting plate is fixed on the fixed cylinder. The connecting plate is located on the side opposite to the forward direction of the fixed cylinder. A scraper plate one is fixed on one bottom side of the connecting plate, and a scraper plate two is fixed on the other bottom side of the connecting plate. The included angle formed by the scraper plate one and the scraper plate two faces the liquid outlet. A gap for liquid flow is formed between one end of the scraper plate one and the scraper plate two. The end of the scraper plate one near the scraper plate two crosses the horizontal center line of the liquid outlet.

[0016] Preferably, a scraper plate three is fixed at the end of the scraper plate two away from the fixed cylinder, and the scraper plate three is parallel to the scraper plate one.

[0017] Preferably, an auxiliary rolling frame is fixed to the side of the fixed cylinder opposite to the forward direction, and an auxiliary support is fixed to the side of the fixed cylinder in the same direction as the forward direction. The auxiliary rolling frame has rolling wheels, the bottom of which is flush with the bottom of the turntable and lower than the bottom of the auxiliary support.

[0018] Preferably, a pusher is fixed on the liquid storage tank, and the pusher is used to push the liquid storage tank forward.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention features a ring of evenly distributed fixed plates inside a fixed cylinder that work in conjunction with a rotating shaft. After the liquid in the storage tank falls into the cavity formed by the two fixed plates, the rotating shaft is naturally driven to rotate by the shift of the liquid's center of gravity. This allows for continuous and uniform feeding without the need for additional electricity or mechanical power, saving energy costs and improving ease of operation. It is especially suitable for outdoor work environments without power.

[0021] The liquid outlet at the bottom of the fixed cylinder of this utility model works in conjunction with the scraping assembly. The scraper plate one and the scraper plate two form an angle facing the liquid outlet, and the end of the scraper plate one crosses the horizontal center line of the liquid outlet. This can initially guide and limit the falling crack filling material to ensure that the material flows into the crack accurately. The gap between the two allows excess material to flow and avoids material accumulation and overflow. Attached Figure Description

[0028] 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.

[0029] Example

[0030] As shown in Figure 1-2, this device mainly includes a fixed cylinder 1, a liquid storage tank 4, a rotating shaft 6, a fixed plate 7, a turntable 8, a scraping assembly 9, an auxiliary rolling frame 2, an auxiliary support 3, and a pushing frame 10.

[0031] The fixed cylinder 1 is a horizontally positioned cylindrical body, serving as the core load-bearing component of the device. It is hollow inside and open at both ends, used for the temporary storage and transport of the grouting material. The storage tank 4 has a funnel-shaped structure and is fixed at the upper center of the fixed cylinder 1. The bottom outlet of the storage tank 4 is fixedly connected to the internal cavity of the fixed cylinder 1. The top of the storage tank 4 has an openable and closable feeding port for storing liquid grouting materials such as asphalt and grouting adhesive, which are supplied to the fixed cylinder 1 by gravity.

[0032] The rotating shaft 6 runs horizontally through both ends of the fixed cylinder 1 along its central axis, and the rotating shaft 6 and the two ends of the fixed cylinder 1 are rotated together by bearings to ensure that the rotating shaft 6 can rotate flexibly. The fixing plate 7 adopts a rectangular steel plate structure, and at least three are provided, preferably four in this embodiment. All fixing plates 7 are evenly distributed in a ring around the rotating shaft 6 and are vertically fixed to the periphery of the rotating shaft 6. The end of the fixing plate 7 away from the rotating shaft 6 is in close contact with the inner wall of the fixed cylinder 1 and is in sliding fit. Two adjacent fixing plates 7 and the inner wall of the fixed cylinder 1 together form an independent cavity for temporarily storing the grouting material. The volume of the cavity changes periodically with the rotation of the rotating shaft 6.

[0033] The turntable 8 is a circular steel plate, and there are two of them. They are coaxially fixedly connected to both ends of the rotating shaft 6. The diameter of the turntable 8 is larger than the diameter of the rotating shaft 6 and larger than the outer diameter of the fixed cylinder 1. Its bottom is in contact with the ground. When the device moves, it rotates synchronously with the rotating shaft 6, which not only limits the axial position of the rotating shaft 6, but also reduces the moving resistance of the device through rolling contact with the ground.

[0034] As shown in Figure 3-4, the scraper assembly 9 includes a connecting plate 904, a scraper plate 1 901, a scraper plate 2 902, and a scraper plate 3 903. The connecting plate 904 is an L-shaped steel plate, vertically fixed to the outer circumference of the fixed cylinder 1 and located on the side opposite to the forward direction of the device, i.e., the rear end of the device. Scraper plate 1 901 and scraper plate 2 902 are both elastic steel plates, respectively inclined and fixed to the bottom sides of the connecting plate 904, forming an angle between them with the opening of the angle facing the liquid outlet 5 at the bottom of the fixed cylinder 1. A gap of 5-10mm is reserved between scraper plate 1 901 and scraper plate 2 902 to allow excess grouting material to flow; the end of scraper plate 1 901 extends beyond the horizontal center line of the liquid outlet 5, which can initially guide the material falling from the liquid outlet 5 to ensure that the material flows accurately to the crack. The scraper plate 3 903 is set parallel to the scraper plate 1 901. One end of the scraper plate 3 903 is vertically fixed to the end of the scraper plate 2 902 away from the fixed cylinder 1. Its length is adapted to the scraper plate 1 901. It is used to scrape the filling material on the crack surface for a second time.

[0035] The auxiliary rolling frame 2 is a U-shaped frame, fixed to the bottom of the rear end of the fixed cylinder 1 on the side opposite to the forward direction. Rolling wheels are installed at both ends of the frame, and the bottom of the rolling wheels is flush with the bottom of the turntable 8. Together, they support the rear end of the device and reduce the resistance to movement. The auxiliary support 3 is an inverted L-shaped support, fixed to the bottom of the front end of the fixed cylinder 1 on the side in the same direction as the forward direction. Its bottom is higher than the bottom of the rolling wheels and the turntable 8, so that the front end can be slightly raised when the device moves, and only the rear end contacts the ground through the rolling wheels and the turntable 8. When stationary, the auxiliary support 3 is on the ground to provide stable support.

[0036] The pusher frame 10 is a portal frame with its bottom two ends fixed to the outer walls of the liquid storage tank 4 on both sides. The top is equipped with a horizontal grip bar, which makes it easy for the operator to push the device forward as a whole.

[0037] The working process of this device is as follows:

[0038] Material preparation: Add sufficient grouting material into the storage tank 4. The material flows into the fixed cylinder 1 through the connection between the storage tank 4 and the fixed cylinder 1. In the initial state, the grouting material first fills the cavity located at the top of the fixed cylinder 1.

[0039] Automatic feeding: When the turntable 8 is lifted off the ground, as the filling material accumulates in the upper cavity, the center of gravity of the cavity shifts, driving the rotating shaft 6 to rotate around the central axis. When the cavity rotates to the lower part of the fixed cylinder 1, the material inside falls to the road surface crack through the liquid outlet 5. At the same time, the new cavity rotates to the upper part and continues to receive the material falling from the liquid storage tank 4. Through the cyclic effect of the center of gravity shift, continuous and uniform feeding without power is achieved.

[0040] Mobile scraping: The operator pushes the device forward along the crack direction using the push frame 10. The rear end of the device contacts the ground through the rolling wheels of the auxiliary rolling frame 2 and the turntable 8 to ensure smooth movement. The material falling from the outlet 5 flows into the crack under the angle between scraper 1 901 and scraper 2 902, and excess material is discharged through the gap between them. As the device moves forward, scraper 3 903 works with scraper 1 901 to perform secondary scraping of the material on the crack surface to ensure uniform material distribution and a flat surface.

[0041] Static support: When it is necessary to pause the operation, the push frame 10 is released, the auxiliary support 3 at the front end of the device is placed on the ground, and together with the rolling wheel and turntable 8 at the rear end, they form a three-point support to prevent the device from tipping over.

[0042] 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.
