Description

Technical Field

[0001] This utility model relates to the field of asphalt concrete pavement technology, and in particular to an asphalt concrete pavement joint treatment machine. Background Technology

[0002] Asphalt concrete pavement refers to pavement with asphalt concrete as the surface layer. It is a mixture made by manually selecting mineral aggregates (crushed stone or crushed gravel, stone chips or sand, mineral powder, etc.) with a certain gradation and mixing them with a certain proportion of road asphalt material under strict control conditions. When jointing asphalt concrete pavement, a joint treatment machine is required to ensure the smoothness of the road.

[0003] A search of Chinese patent "A Device for Treating Joints in Asphalt Concrete Pavement," publication number "CN220150051U," reveals that this patent describes a process where asphalt concrete flows from the inside of a discharge pipe and through a pouring head to the joint area for filling. A height control component lowers the mounting box, lateral movement component, and mounting plate, disengaging the pouring head from the end of the discharge pipe. The lateral movement component then moves the mounting plate, positioning the pouring heads below the discharge pipe. Finally, the height control component raises the mounting plate and pouring heads, allowing the pouring heads to fit over the end of the discharge pipe, thus treating the joint. The pouring head is replaced with different specifications to fit cracks of different widths, thus avoiding waste of asphalt concrete and ensuring the efficiency of crack filling. The device agitates the asphalt concrete using a stirring component and opens a control valve to allow the asphalt concrete to flow out from the discharge pipe and through the pouring head to fill the crack. However, when the device delivers the asphalt concrete to the crack, the asphalt concrete is prone to unevenness, affecting the joint effect of the asphalt concrete pavement and making it inconvenient to create smooth joints, thus reducing the effectiveness of the device.

[0004] Therefore, an asphalt concrete pavement joint treatment machine is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an asphalt concrete pavement joint treatment machine to solve the above-mentioned problems, thereby improving the inconvenience of smoothing joints in asphalt concrete pavements.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: an asphalt concrete pavement joint treatment machine includes a base plate, a material storage cylinder installed on the top of the base plate, a discharge pipe connected to one side of the material storage cylinder, and a leveling mechanism provided at the bottom of one side of the base plate; wherein, the leveling mechanism includes a limiting frame disposed on one side of the bottom of the base plate, a smoothing block slidably connected to the inner wall of the limiting frame, two fixing blocks fixedly connected to one side of the limiting frame, and two electric push rods installed on one side of the inner wall of the base plate, one end of the electric push rod penetrating the base plate and fixedly connected to the fixing blocks, the discharge pipe transports asphalt concrete into the limiting frame, and as the base plate moves the limiting frame, the smoothing block can smooth the concrete in the crack, and the two electric push rods can drive the smoothing block to contact the ground to smooth the asphalt concrete, thereby improving the smoothness of the asphalt concrete pavement joint.

[0007] Preferably, the leveling mechanism further includes two sliders fixedly connected to the rear end of the leveling block. The sliders are slidably connected to the inner wall of the leveling block. A compression spring is provided at the top of the slider. When the limiting frame contacts the ground with the leveling block, it will drive the two sliders to squeeze the compression spring. The compression spring applies pressure to the leveling block through its own elasticity, so that the leveling block can fit with the ground and improve the leveling effect.

[0008] Preferably, limit blocks are provided at both ends of the inner wall of the compression spring, and the two limit blocks are fixedly connected to the slider and the limit frame respectively, so that the two limit blocks can limit the compression spring.

[0009] Preferably, a calibration block is fixedly connected to the middle of the rear end of the limiting frame. The calibration block is aligned with the discharge pipe, which can adjust the position of the discharge pipe and improve the joint effect.

[0010] Preferably, a fixing plate is fixedly connected to one side of the base plate, and the discharge pipe is disposed on the inner wall of the fixing plate.

[0011] Preferably, a cleaning plate is fixedly connected to the front end of the limiting frame. When the crack is being repaired, the cleaning plate can scrape away impurities on the ground to prevent the impurities from affecting the use of the limiting frame.

[0012] Preferably, a cleaning brush is fixedly connected to one end of the inner wall of the cleaning plate, and one end of the cleaning brush extends to the outside of the cleaning plate. The cleaning brush and the cleaning plate work together to improve the cleaning effect and facilitate the jointing of road surface gaps.

[0013] The beneficial effects of this utility model are:

[0014] 1. When jointing cracks, the discharge pipe can transport asphalt concrete into the limiting frame, and then the asphalt concrete in the limiting frame is transported into the crack through the smoothing block, and the asphalt concrete is smoothed. The bottom of the smoothing block is tilted to one side, which can improve the smoothing effect of the asphalt concrete. The inner wall of the smoothing block is V-shaped, which can gather the asphalt concrete in the middle and improve the jointing effect. Two electric push rods can drive the limiting frame and the smoothing block to fit with the ground. The compression spring and the slider can apply pressure to the smoothing block to improve the smoothing effect. The fixing plate can fix the discharge pipe, and the calibration block can adjust the pouring position of the discharge pipe. It can perform smooth jointing of asphalt concrete pavement and improve the smoothness of the road surface.

[0015] 2. When jointing asphalt concrete pavement, the cleaning plate moves downward with the limiting frame and contacts the ground. The movement of the base plate can scrape away impurities on the ground, improving the jointing effect of the device. The cleaning plate further cleans through the cleaning brush on the inner wall. The V-shaped front end of the cleaning plate can clean impurities to both sides of the cleaning plate, which can improve the jointing effect of the joint treatment machine.

[0021] 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.

[0022] In practical implementation: such as Figure 1-4As shown, an asphalt concrete pavement joint treatment machine includes a base plate 1, a storage cylinder 2 installed on the top of the base plate 1, a discharge pipe 3 connected to one side of the storage cylinder 2, and a leveling mechanism 4 installed at the bottom of one side of the base plate 1. The leveling mechanism 4 includes a limiting frame 401 installed on one side of the bottom of the base plate 1, a smoothing block 402 slidably connected to the inner wall of the limiting frame 401, two fixing blocks 403 fixedly connected to one side of the limiting frame 401, and two electric push rods 404 installed on one side of the inner wall of the base plate 1. One end of the electric push rod 404 passes through the base plate 1 and is fixedly connected to the fixing block 403.

[0023] like Figure 2 and Figure 3 As shown, the leveling mechanism 4 also includes two sliders 405 fixedly connected to the rear end of the smoothing block 402. The sliders 405 are slidably connected to the inner wall of the smoothing block 402. A compression spring 406 is provided at the top of the slider 405. Limiting blocks 407 are provided at both ends of the inner wall of the compression spring 406. The two limiting blocks 407 are fixedly connected to the slider 405 and the limiting frame 401 respectively. A calibration block 408 is fixedly connected to the middle of the rear end of the limiting frame 401. A fixing plate 409 is fixedly connected to one side of the base plate 1. The discharge pipe 3 is set on the fixed plate 409. On the inner wall of the fixed plate 409, the electric push rod 404 drives the limiting frame 401 on one side of the fixed block 403 and the smoothing block 402 to move downwards and contact the ground, and causes the two sliders 405 to move upwards to squeeze the compression spring 406. The limiting block 407 can limit the compression spring 406, and the compression spring 406 can apply pressure to the smoothing block 402 to make it fit tightly with the ground and improve the smoothing effect. The calibrating block 408 can adjust the pouring position of the discharge pipe 3 to improve the flatness of the joint of the device.

[0024] like Figure 4 As shown, a cleaning plate 410 is fixedly connected to the front end of the limiting frame 401. A cleaning brush 411 is fixedly connected to one end of the inner wall of the cleaning plate 410. One end of the cleaning brush 411 extends through to the outside of the cleaning plate 410. As the joint treatment machine moves, the limiting frame 401 can drive the cleaning plate 410 and the cleaning brush 411 to move to one side to clean the impurities on the ground that needs to be joined, improve the joint effect of the device, and reduce the impact of impurities on the use effect of the limiting frame 401.

[0025] In use, the PLC controller on the joint treatment machine can start the conveying pump on the storage cylinder 2 to transport asphalt concrete into the discharge pipe 3. The valve can be opened by manually turning it to allow the asphalt concrete to be transported into the limiting frame 401. During the transport of asphalt concrete, the PLC controller drives the electric push rod 404 to cooperate with the fixed block 403 to move the limiting frame 401 and the smoothing block 402 downward to fit against the ground. The smoothing block 402 drives the slider 405 to squeeze the compression spring 406. The compression spring 406 applies pressure to the smoothing block 402 through its own elasticity. As the base plate 1 moves, the smoothing block 402 can smooth the asphalt concrete in the crack. When the limiting frame 401 moves, it drives the cleaning plate 410 and the cleaning brush 411 to clean the impurities on the cracked ground.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
