Description

Technical Field

[0001] This utility model belongs to the field of road repair technology, specifically a crack sealing device. Background Technology

[0002] Highway maintenance refers to the upkeep and maintenance of highways. Upkeep focuses on the entire process from the time a road is completed and opened to traffic, while maintenance focuses on repairing damaged sections. Cracks are one of the main forms of early-stage highway defects. Crack sealing is a preventative maintenance method for road surface defects. It mainly involves using a crack sealing device to inject asphalt into the cracks through pipes to irrigate them.

[0003] Existing crack sealing devices are generally used in conjunction with grooving machines, crack sealing machines, and blowers (or hot spray guns). They typically employ a liquefied gas heating system, which uses heat-conducting oil circulation to rapidly melt the asphalt or crack sealant, thereby ensuring the fluidity of the material and allowing it to be smoothly injected into the cracks.

[0004] However, existing crack sealing devices cannot smooth the material at the crack opening in a timely manner after the crack sealing is completed. It is necessary to use auxiliary tools to smooth the material afterward. However, because the material is not processed in time for a long time, the asphalt material may solidify after crack sealing, resulting in an uneven crack opening, which in turn affects the normal driving of subsequent vehicles.

[0005] Therefore, a crack filling device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a crack filling device.

[0007] The technical solution adopted by this utility model to solve its technical problem is a crack filling device, including a mobile vehicle. A storage cylinder is provided on one side of the top of the mobile vehicle, and a support frame is distributed on one side of the storage cylinder. A smoothing structure is provided at the bottom of one end of the mobile vehicle.

[0008] The smoothing structure includes a first motor fixedly installed at the top center of the support frame, and the output end of the first motor is connected to a drive wheel. The bottom of the drive wheel is connected to a rotating shaft, and the other end of the rotating shaft is connected to a rotating seat. A damper is provided on the inner side of the bottom of the rotating seat, and a buffer spring is sleeved on the outer surface of the damper. A turntable is connected to the bottom of the damper, and a smoothing roller is provided on the inner side of the bottom of the turntable.

[0009] Preferably, the outer surface of the driving wheel is fitted with a belt, and the inner side of the other end of the belt is connected to a driven wheel. The bottom of the driven wheel is connected to a connecting plate, and the bottom of the connecting plate is provided with a stirring frame. The inner side wall of the stirring frame is connected to a dividing rod. The driven wheel is rotatably connected to the driving wheel through the belt, which facilitates the subsequent movement of the connecting plate by rotating the driven wheel.

[0010] Preferably, a second motor is fixedly installed on the inner side of one end of the mobile vehicle, and the output end of the second motor is connected to a threaded rod. A threaded sleeve is fitted on the outer surface of the threaded rod, and an adjustment frame is provided at one end of the threaded sleeve. The rotation of the threaded sleeve can realize the synchronous movement of the adjustment frame, which facilitates the subsequent adjustment of the lateral position of the filling head.

[0011] Preferably, an electric cylinder is installed on the side of the adjusting frame away from the threaded sleeve, and the other end of the electric cylinder is connected to a movable seat. One end of the movable seat is provided with a guide block, and the side of the movable seat away from the electric cylinder is connected to a filling head.

[0012] Preferably, a discharge pipe is connected to one side of the bottom of the storage cylinder, and a pump is installed on the surface of the discharge pipe. The other end of the discharge pipe is connected to a flexible hose with a stretching effect, and the flexible hose is connected to the movable seat.

[0013] Preferably, the smoothing rollers are equidistantly distributed along the center of the turntable, and the smoothing rollers and the turntable rotate together, so that the asphalt after grouting can be smoothed by the rotation of the smoothing rollers.

[0014] The advantages of this utility model are:

[0015] 1. This utility model, through its structure including a first motor, rotating shaft, damper, buffer spring, and smoothing roller, facilitates effective smoothing of the area after grouting. This prevents the overflowing asphalt from being unevenly spread out, which could lead to unevenness at the asphalt solidification joint. Compared to manual smoothing, this method is not only more efficient but also produces a better smoothing effect, making it more practical overall.

[0016] 2. This utility model, through its structure of drive wheel, belt, and driven wheel, facilitates the rotation of the connecting plate. The rotating connecting plate then drives the mixing frame and dividing rod to rotate synchronously. This allows the rotating mixing frame and dividing rod to effectively mix the asphalt stored inside the storage cylinder, preventing the asphalt from solidifying due to prolonged stillness and affecting subsequent discharge.

[0024] 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 scope of protection of the present utility model.

[0025] Please see Figure 1-5 As shown, a crack filling device includes a mobile vehicle 1, a material storage cylinder 2 is provided on one side of the top of the mobile vehicle 1, and a support frame 3 is distributed on one side of the material storage cylinder 2. A smoothing structure is provided at the bottom of one end of the mobile vehicle 1.

[0026] The smoothing structure includes a first motor 4 fixedly installed at the top center of the support frame 3, and the output end of the first motor 4 is connected to a drive wheel 5. The bottom of the drive wheel 5 is connected to a rotating shaft 6, and the other end of the rotating shaft 6 is connected to a rotating seat 7. A damper 8 is provided on the bottom inner side of the rotating seat 7, and a buffer spring 9 is sleeved on the outer surface of the damper 8. A turntable 10 is connected to the bottom of the damper 8, and a smoothing roller 11 is provided on the bottom inner side of the turntable 10.

[0027] During operation, asphalt is fed into the inner side of the storage cylinder 2 through the inlet on one side of the top of the storage cylinder 2. At this time, the first motor 4 works, causing the drive wheel 5 connected to its output end to rotate. Then, the rotation of the drive wheel 5 realizes the synchronous rotation of its bottom rotating shaft 6. At this time, the rotation of the rotating shaft 6 drives the rotating seat 7 to move synchronously. In turn, the rotation of the rotating seat 7 realizes the synchronous movement of the turntable 10. Since the smoothing roller 11 and the turntable 10 are rotatably connected, the movement of the smoothing roller 11 can be realized by the rotation of the turntable 10. Thus, the rotation of the smoothing roller 11 is used to smooth the asphalt after the crack is filled. At the same time, when the smoothing roller 11 is subjected to longitudinal force, the turntable 10 will squeeze the damper 8 and the buffer spring 9. Then, the reverse force generated by the deformation of the damper 8 and the buffer spring 9 will play a role in buffering and protection. At the same time, it can make better contact between the smoothing roller 11 and the ground.

[0028] A belt 12 is fitted on the outer surface of the drive wheel 5, and a driven wheel 13 is connected to the inner side of the other end of the belt 12. A connecting plate 14 is connected to the bottom of the driven wheel 13, and a stirring rack 15 is provided at the bottom of the connecting plate 14. A dividing rod 16 is connected to the inner side wall of the stirring rack 15.

[0029] During operation, since the driving wheel 5 is rotatably connected to the driven wheel 13 via the belt 12, when the driving wheel 5 rotates, the belt 12 will drive the driven wheel 13 located on the inner side of its other end to rotate as well. Then, the rotation of the driven wheel 13 will drive the connecting plate 14 fixedly connected to its bottom to move synchronously through the connecting shaft. At this time, the rotation of the connecting plate 14 will drive the mixing frame 15 to rotate, and the rotation of the mixing frame 15 will realize the synchronous movement of the dividing rod 16, thereby achieving effective mixing and stirring of the asphalt inside the storage cylinder 2 and preventing the asphalt from solidifying.

[0030] A second motor 17 is fixedly installed on the inner side of one end of the mobile vehicle 1, and the output end of the second motor 17 is connected to a threaded rod 18. A threaded sleeve 19 is fitted on the outer surface of the threaded rod 18, and an adjustment bracket 20 is provided at one end of the threaded sleeve 19.

[0031] When the second motor 17 is working, the threaded rod 18 connected to its output end will rotate accordingly. Then, the rotation of the threaded rod 18 will cause the threaded sleeve 19 connected to its outer surface to move laterally. In this way, the lateral movement of the threaded sleeve 19 can be used to adjust the lateral position of the adjusting frame 20, which will facilitate the subsequent adjustment of the lateral position of the grouting head 24, so as to better grout the ground gaps.

[0032] An electric cylinder 21 is installed on the side of the adjusting frame 20 away from the threaded sleeve 19, and the other end of the electric cylinder 21 is connected to a movable seat 22. A guide block 23 is provided on one end of the movable seat 22, and a filling head 24 is connected to the side of the movable seat 22 away from the electric cylinder 21.

[0033] During operation, the electric cylinder 21 pushes the movable seat 22, causing it to slide along the adjusting frame 20. At this time, the movable seat 22 drives the guide block 23 to slide along the groove opened on the side wall of the adjusting frame 20, thereby improving the stability of the movable seat 22 during movement. Since the movable seat 22 has a hollow structure and is connected to the filling head 24, when asphalt is input into the inner side of the movable seat 22, it will be input into the inner side of the filling head 24, which will facilitate subsequent discharge through the filling head 24 to achieve the purpose of filling the crack.

[0034] A discharge pipe 25 is connected to one side of the bottom of the storage cylinder 2, and a pump 26 is installed on the surface of the discharge pipe 25. A hose 27 is connected to the other end of the discharge pipe 25.

[0035] During operation, the pump 26 draws the asphalt inside the storage cylinder 2 into the inside of the discharge pipe 25, and then through the discharge pipe 25 into the inside of the hose 27, facilitating the subsequent discharge of the asphalt.

[0036] The smoothing rollers 11 are equidistantly distributed along the center of the turntable 10, and the smoothing rollers 11 and the turntable 10 rotate together;

[0037] During operation, the turntable 10 rotates, and the rotation of the turntable 10 is used to realize the synchronous movement of the smoothing roller 11, thereby using the movement of the smoothing roller 11 to achieve the smoothing treatment of asphalt.

[0038] Working principle: During use, asphalt is fed into the inner side of the storage cylinder 2 through the inlet on one side of the top of the storage cylinder 2. At this time, the first motor 4 works and the drive wheel 5 connected to its output end rotates accordingly. Since the drive wheel 5 is rotatably connected to the driven wheel 13 through the belt 12, the rotation of the drive wheel 5 will cause the belt 12 to drive the driven wheel 13 set on the inner side of its other end to rotate accordingly. Then, the rotation of the driven wheel 13 drives the connecting plate 14 fixedly connected to its bottom to move synchronously through the connecting shaft. At this time, the rotation of the connecting plate 14 drives the mixing frame 15 to rotate, and the rotation of the mixing frame 15 is used to realize the synchronous movement of the dividing rod 16, thereby achieving effective mixing and stirring of the asphalt inside the storage cylinder 2 and preventing the asphalt from solidifying.

[0039] During the crack filling process, when the second motor 17 is working, the threaded rod 18 connected to its output end will rotate accordingly. Then, the rotation of the threaded rod 18 will cause the threaded sleeve 19 connected to its outer surface to move laterally. This lateral movement of the threaded sleeve 19 will adjust the lateral position of the adjusting frame 20, which will facilitate the subsequent adjustment of the lateral position of the crack filling head 24, thus better filling the ground cracks. When the electric cylinder 21 is working, it will push the movable seat 22, which will then slide along the adjusting frame 20. At this time, the movable seat 22 will drive the guide block 23 to slide along the sliding groove opened on the side wall of the adjusting frame 20, thereby improving the stability of the movable seat 22 during the movement. Since the movable seat 22 is a hollow structure and is connected to the crack filling head 24, when asphalt is input into the inner side of the movable seat 22, it will be input into the inner side of the crack filling head 24, which will facilitate the subsequent discharge through the crack filling head 24, thus achieving the purpose of crack filling.

[0040] After the crack filling is completed, the rotation of the drive wheel 5 is used to realize the synchronous rotation of its bottom shaft 6. At this time, the rotation of the shaft 6 drives the rotating seat 7 to move synchronously, and then the rotation of the rotating seat 7 realizes the synchronous movement of the turntable 10. Since the smoothing roller 11 and the turntable 10 are connected by rotation, the movement of the smoothing roller 11 can be realized by the rotation of the turntable 10. Thus, the rotation of the smoothing roller 11 is used to smooth the asphalt after crack filling. At the same time, when the smoothing roller 11 is subjected to longitudinal force, the turntable 10 will squeeze the damper 8 and the buffer spring 9. Then, the reverse force generated by the deformation of the damper 8 and the buffer spring 9 will play a role in buffering and protection, and at the same time, it can make better contact between the smoothing roller 11 and the ground.
