[0037] Reference Figures 1 to 7 The present invention provides an asphalt pavement crack repairing device 100 .

[0038] In the embodiment of the present invention, the asphalt pavement crack repair device 100 includes a mounting frame 10; a moving mechanism 20 is mounted on the mounting frame 10; a liquid storage mechanism includes a liquid storage barrel 31, a stirring drive motor 32 and a stirring rod 33, wherein the liquid storage barrel 31 is arranged on the mounting frame 10 and forms a liquid storage cavity 31a, the stirring drive motor 32 is installed on the liquid storage barrel 31, and the stirring rod 33 is arranged in the liquid storage cavity 31a and is connected to the stirring drive motor 32 by transmission; a liquid injection mechanism 40, including a liquid injection drive member (not shown), a liquid injection tube 42 and a rolling switch valve 43, the liquid injection drive member is installed on the mounting frame 10, the liquid injection tube 42 is connected to the liquid storage chamber 31a, and is provided with a liquid outlet 42a, the rolling switch valve 43 is arranged at the liquid outlet 42a, the liquid injection drive member is connected to the liquid injection tube 42, and can drive the liquid injection tube 42 to rise and fall relative to the mounting frame 10, so that the rolling switch valve 43 blocks or rolls to open the liquid outlet 42a.

[0039] Specifically, in the present invention, the mounting frame 10 is formed by welding or screwing metal profiles, and the moving mechanism 20 includes a plurality of wheels and a moving motor. The plurality of wheels are arranged at intervals at the bottom of the mounting frame 10, and the moving motor is installed on the mounting frame 10 and is connected to the plurality of wheels by transmission. The moving motor drives the plurality of wheels to rotate, so as to drive the mounting frame 10 to move on the asphalt repair road surface.

[0040] In the present invention, asphalt is contained in the liquid storage chamber 31a, and the stirring drive motor 32 drives the stirring rod 33 to rotate to stir the asphalt to prevent it from coagulating. When repairing the asphalt pavement, the moving mechanism 20 drives the mounting frame 10 to move to a preset position, or the moving mechanism 20 drives the mounting frame 10 to move along a preset trajectory. When reaching or moving along the preset trajectory, the injection drive drives the injection pipe 42 to move downward relative to the mounting frame 10, and the rolling switch valve 43 is subjected to the force of the repaired pavement to open the liquid outlet 42a, and the asphalt flows out from the liquid outlet 42a and is poured into the crack. When the mounting frame 10 moves, that is, when the injection pipe 42 continues to repair the crack, the rolling switch valve 43 is subjected to the friction force and can roll relative to the repaired pavement, continuously opening the liquid outlet 42a, so that the asphalt continues to flow out. After the repair is completed, the injection drive drives the injection pipe 42 to move upward relative to the mounting frame 10, and the rolling switch valve 43 re-blocks the liquid outlet 42a, and so on. It can be seen from the above process that in the present invention, the rolling switch valve 43 can roll relative to the repaired pavement when repairing cracks in the asphalt pavement, that is, it can avoid the injection tube 42 from being stuck by rolling, and when the asphalt flows into the crack, the rolling switch valve 43 can also press the asphalt into the crack at the same time. In this way, there is no need to set up an additional vibration mechanism. The asphalt pavement crack repair device 100 can smoothly repair the cracks while having high working stability and installability.

[0041] Please see again Figures 5 to 7 In the present invention, the rolling switch valve 43 includes a mounting ball seat 431 and a rolling ball 432, wherein the mounting ball seat 431 includes a seat body and a connecting rod connected to the seat body, and the injection tube 42 is provided with a sliding connection groove (not shown in the figure), and the connecting rod can be slidably inserted into the sliding connection groove to slide the seat body and the injection tube 42. The seat body is hemispherical, and a ball groove 431a is formed by mechanical processing, and the rolling ball 432 can be rolled and embedded in the ball groove 431a. In this embodiment, the mounting ball seat 431 has a blocking position and a liquid injection position relative to the injection tube 42. When in the blocking position, the outer side surface of the mounting ball seat 431 abuts against the side wall surface of the liquid outlet 42a. It can be understood that when in the blocking position, the mounting ball seat 431 is subjected to the gravity of itself and the rolling ball 432, and moves upward. Since the ball diameter of the mounting ball seat 431 is larger than the diameter of the liquid outlet 42a, the mounting ball seat 431 blocks the liquid outlet 42a. In the injection position, the injection drive drives the injection tube 42 to move downward, so that the rolling ball 432 is subjected to the force from the repaired road surface, and the rolling ball 432 moves upward, thereby pushing the mounting ball seat 431 away from the liquid outlet 42a, and the asphalt flows out from the gap between the two. When the mounting frame 10 moves, the rolling ball 432 can roll relative to the repaired road surface, thereby avoiding jamming. The rolling switch valve 43 has a simple structure and can effectively avoid jamming.

[0042] It should be noted that, in the present application, the ball diameter of the rolling ball 432 should be larger than the width of the crack in the asphalt pavement, so that the rolling ball 432 can roll on the surface of the crack, thereby avoiding getting stuck.

[0043] Furthermore, the surface of the rolling ball 432 is concavely formed with a plurality of guide grooves 432a, which are formed by mechanical processing and have a semicircular cross section. The guide grooves 432a extend along the maximum trajectory of the rolling ball 432, and the plurality of guide grooves 432a are interlaced. In the present application, by providing a plurality of guide grooves 432a, the fluidity and viscosity of the asphalt can be fully utilized, and when the asphalt flows out from the gap between the rolling ball 432 and the liquid outlet 42a, the asphalt is further guided to the end of the rolling ball 432, thereby preventing the asphalt from being poured on the repaired road surface and not accurately entering the cracks. That is, by providing a plurality of guide grooves 432a, the loss of asphalt can be avoided to a large extent, and the repair effect of the cracks can be improved.

[0044] Furthermore, in the present invention, the rolling switch valve 43 further includes a blocking spring 433 elastically connected to the mounting ball seat 431 and the injection tube 42, the blocking spring 433 is partially accommodated in the sliding connection groove, the connecting rod of the mounting ball seat 431 extends into the hollow part of the blocking spring 433, and the seat body compresses the blocking spring 433. At this time, the elastic force of the blocking spring 433 acts to make the seat body of the mounting ball seat 431 block the liquid outlet 42a. By providing the blocking spring 433, the working performance of the switch of the rolling switch valve 43 can be made more stable.

[0045] Please see again Figure 2 and Figure 3 In one embodiment of the present invention, the injection drive member includes a driving cylinder 411 and a first mounting seat 412. The driving cylinder 411 is mounted on the frame. The first mounting seat 412 is fixed to the telescopic rod of the driving cylinder 411 by screws and is provided with a snap-in groove. The shape of the snap-in groove is adapted to the shape of the injection tube 42, so that the injection tube 42 can be snapped into the snap-in groove, so that the disassembly and assembly of the injection tube 42 is more convenient. The driving cylinder 411 drives the injection tube 42 to rise and fall relative to the mounting frame 10, so that the rolling ball 432 abuts against the repaired road surface. By setting the driving cylinder 411, the present application can further facilitate the user to place the injection tube 42 on the surface of the crack when repairing the asphalt road surface. At the same time, since the injection tube 42 and the first mounting seat 412 are easy to assemble and disassemble, it is also convenient for users to switch between automatic repair and manual repair to a large extent. That is, the injection tube 42 is removed from the first mounting seat 412, and the injection tube 42 is manually placed on the surface of the crack for pouring. In this way, the asphalt pavement crack repair device 100 can better adapt to different repair situations and is more practical.

[0046] Furthermore, the injection drive member also includes two horizontal linear modules 413 and a connecting balance plate 414, the two horizontal linear modules 413 are spaced apart on the mounting frame 10, the connecting balance plate 414 connects the two horizontal linear modules 413, and the driving cylinder 411 is fixedly connected to the connecting balance plate 414. Specifically, in the present application, the asphalt pavement crack repair device 100 also includes a display control screen 50 and a camera 60 installed on the mounting frame 10, wherein the stirring driving motor 32, the two horizontal linear modules 413, the driving cylinder 411 and the camera 60 are connected to the display control screen 50 via electronic connection lines or wireless communication modules, such as WIFI, Bluetooth communication. In one mode, the camera 60 can take a real-time photo of the repaired road surface and transmit the photo to the side of the display control screen 50. The user controls the movement of the mounting frame 10 and the injection mechanism 40 according to the photo, that is, the mounting frame 10 moves to a preset position, the two horizontal linear modules 413 fine-tune the position of the injection pipe 42 in the horizontal direction, and the driving cylinder 411 drives the injection pipe 42 to move downward to repair the crack. In another mode, the repair path can be input in advance in the display control screen 50, and the moving mechanism 20 drives the mounting frame 10 to move according to the repair path, and then the horizontal linear module 413 and the driving cylinder 411 cooperate with each other to drive the injection pipe 42 to move to repair the crack.

[0047] Please see again Figure 4 and Figure 5 In one embodiment of the present invention, the stirring rod 33 includes a rod body 331 and a spiral extension 332, wherein the rod body 331 is transmission-connected to the output shaft of the stirring drive motor 32, and the spiral extension 332 is used to stir the asphalt and squeeze the asphalt toward the lower part of the liquid storage barrel 31. At the same time, along the discharge direction, the cross-section of the liquid storage barrel 31 is gradually reduced, that is, the liquid storage barrel 31 is conically arranged. In the present application, through the conically arranged liquid storage barrel 31 and the stirring rod 33 with the spiral extension 332, the asphalt can be pressed into the injection pipe 42 to the greatest extent, so that the asphalt flowing out of the injection pipe 42 has a higher injection speed and obtains a higher injection pressure, and can then flow more fully into the gap in the crack to improve the repair effect of the crack.

[0048] Furthermore, in the present invention, the injection mechanism 40 further includes a flattening roller 44, a mounting rod 45 and a torsion spring (not shown), wherein the mounting rod 45 is rotatably connected to the mounting frame 10, and the flattening roller 44 is rotatably connected to the end of the mounting rod 45 and is located downstream of the injection pipe 42, that is, when the mounting frame 10 moves forward, the flattening roller 44 is located behind the injection pipe 42, and the torsion spring is elastically connected to the mounting rod 45 and the mounting frame 10, and the torsion spring provides elastic force, so that the flattening roller 44 continues to fit the repaired road surface. After pouring asphalt, the flattening roller 44 further presses the asphalt into the cracks, so that the effect of asphalt road repair is better.

[0049] See also Figure 8 In order to further improve the repair effect of the asphalt pavement, in one embodiment of the present invention, the asphalt pavement crack repair device 100 also includes a vibration mechanism 70, which includes a second mounting seat 71 and a vibration rod 72 rotatably connected thereto, and a vibration motor (not shown). The second mounting seat 71 is provided with a connecting shaft hole (not shown), and the end of the vibration rod 72 is provided with a connecting shaft (not shown) adapted thereto, which is rotatably sleeved in the connecting shaft hole to rotatably connect the vibration rod 72 and the second mounting seat 71. The vibration motor is fixed on the second mounting seat 71, and the mechanical vibration generated by the vibration motor is transmitted from the second mounting seat 71 to one side of the vibration rod 72, and the vibration rod 72 is located between the flattening roller 44 and the injection pipe 42. In actual use, after the injection pipe 42 is poured with asphalt, the vibration rod 72 vibrates the asphalt in the crack so that it fully penetrates into the crack, thereby achieving a better crack repair effect. On the other hand, since the vibration rod 72 is rotatably connected to the second mounting seat 71, the vibration rod 72 can be prevented from being blocked by obstacles and stuck when actually inserted into the crack, and the asphalt pavement crack repairing device 100 can run more smoothly.

[0050] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
