Description

Technical Field

[0001] The utility model relates to the technical field of roads, in particular to a road maintenance crack filling device. Background Technique

[0002] Since roads are mainly used for various vehicles to pass through, when various vehicles drive on the road surface, a large frictional force will be generated between the vehicles and the road surface. These frictional forces will cause wear to the asphalt layer of the road surface. Coupled with the fact that the road is exposed to the external environment and is long-term affected by sunlight and rain erosion, it will also cause erosion to the asphalt layer of the road surface. Over time, cracks will appear on the road surface. If not repaired in time, the road surface condition will deteriorate further.

[0003] When repairing asphalt roads, the most commonly used method is to pour sealant into the cracks to fill the cracks completely, so as to prevent rainwater from seeping into the road base through the cracks, resulting in the washing out of the sand and gravel of the road base, and then avoiding the formation of roadbed cavities and road surface collapses, ensuring the safety of vehicles and personnel driving on the road surface.

[0004] The Chinese invention patent with the patent application number 202210361310.0 records a road maintenance crack filling device. The asphalt box is provided with asphalt, and the asphalt flows out through the discharge pipe into the cracks. Rotate the screw rod, and the screw rod drives the bearing and the block to move, so that the block approaches or moves away from the discharge pipe. The block can be used to block the inside of the discharge pipe, thereby adjusting the flow rate of the asphalt flowing out of the discharge pipe. When in use, first adjust the rotation of the screw rod according to the size of the crack to adjust the position of the block. Then, the asphalt flows out from the bottom of the discharge pipe into the cracks. The user can push the transport vehicle to repair the entire crack. However, after injecting the sealant into the cracks in the above device, it is necessary for the staff to manually sprinkle sand evenly on the repaired crack surface to prevent the subsequent vehicle wheels from directly contacting the sealant and causing the sealant to adhere to the wheel surface. When the crack length is relatively long, the operation of manually sprinkling sand is time-consuming and laborious, which will lead to too long road closure time and seriously affect traffic efficiency. Content of the Utility Model

[0005] The purpose of this application is to provide a road maintenance crack filling device to solve the problem that it is necessary to manually sprinkle sand on the surface of the sealant as mentioned in the above background technique. When the road surface crack is relatively long, this operation is time-consuming and laborious, which will lead to too long road closure time and seriously affect traffic efficiency.

[0006] To achieve the above object, the present application provides the following technical solution: A road maintenance caulking device, including a bottom plate, four rollers are fixedly installed at the four corners of the bottom of the bottom plate, a glue tank is fixedly connected to the top of the bottom plate, a glue outlet pipe is communicated with the bottom of the glue tank, the bottom end of the glue outlet pipe penetrates through the bottom of the bottom plate, a glue pump is communicated with the glue outlet pipe, a sand hopper is fixedly connected to the top of the bottom plate, a sand outlet pipe is communicated with the bottom of the sand hopper, the bottom end of the sand outlet pipe penetrates through the bottom of the bottom plate, a sand dividing plate is fixedly connected to the bottom of the bottom plate, the bottom plate is provided with a sand leveling assembly, and a spreading plate is fixedly connected to the bottom of the bottom plate.

[0007] Preferably, the sand leveling assembly includes two groups of sand scraping plates movably arranged at the bottom of the bottom plate. The number of sand scraping plates in each group is several and they are equidistantly distributed from left to right in sequence. The two groups of sand scraping plates are staggered. The sand leveling assembly further includes a driving unit. The driving unit is used to push the two groups of sand scraping plates to reciprocally move away from or close to each other to evenly stir the sand to the front and back sides. The advantage of this setting is that when the two groups of staggered sand scraping plates alternately approach or move away from each other, the sand falling on the surface of the caulking glue from the sand outlet pipe can be evenly pushed to both sides, so that the subsequent spreading plate can push these sands more evenly on the surface of the caulking glue. In this way, the uniformity of sand spreading is ensured, effectively preventing the caulking glue from being adhered and taken away by the wheels of subsequent vehicles after passing over the surface of the caulking glue, ensuring that the repair of the road surface cracks will not be damaged and ensuring the safety of the road surface.

[0008] Preferably, the driving unit includes two rotating blocks symmetrically and rotatably connected to the bottom of the bottom plate. Two fixing rods are symmetrically and fixedly connected to the right side surfaces of the two rotating blocks. The two groups of sand scraping plates are respectively fixedly connected to the bottoms of the two fixing rods. The driving unit further includes two cylinders symmetrically and fixedly connected to the top of the bottom plate. A driving member is installed at the output ends of the two cylinders. The driving member includes two inclined surfaces symmetrically arranged. The driving member is located between the two fixing rods and the two inclined surfaces are simultaneously in contact with the side surfaces of the two fixing rods. As the driving member moves up and down, it can push the two fixing rods to rotate in the direction of approaching or moving away from each other. The advantage of this setting is that by pushing the driving member to reciprocally move up and down by the cylinder, the two fixing rods can be pushed to rotate in the horizontal direction in the direction of approaching or moving away from each other. In this way, the sand leveled by the two groups of sand scraping plates is distributed in an arc shape, and the lengths of multiple paths of leveled sand gradually increase from left to right. Thus, when the multiple paths of sand are leveled by the spreading plate, they can be more evenly distributed on the surface of the caulking glue, further improving the effect and reliability of the sand spreading work and improving the effect of preventing the caulking glue from adhering to the wheels.

[0009] Preferably, the driving unit further includes two groups of rotating rings rotatably connected to the outer sides of the two fixing rods. The number of each group of rotating rings is equal to the number of each group of sand scraping plates. The tops of the two groups of sand scraping plates are respectively fixedly connected to the bottoms of the two groups of rotating rings. The driving member is composed of two groups of triangular blocks. The number of each group of triangular blocks is equal to the number of each group of rotating rings. The included angle between the inclined surfaces of several triangular blocks in each group and the horizontal plane gradually decreases from left to right. The inclined surfaces of the two groups of triangular blocks are respectively in contact with the outer circumferential surfaces of the two groups of rotating rings. The tops of the two groups of triangular blocks are both fixedly connected with straight rods. The tops of the two straight rods penetrate through the top of the bottom plate and are fixedly connected with the same push plate. The two straight rods are movably inserted into the bottom plate. The push plate is fixedly connected with the output ends of the two air cylinders. The advantage of such a setting is that while pushing the two groups of sand scraping plates to rotate alternately towards each other or away from each other, the two groups of sand scraping plates can be driven by the rotating rings to swing reciprocally in the vertical direction, thereby further improving the effect and reliability of the sand spreading work.

[0010] Preferably, the cross-section of the sand scraping plate is a rhombus, and the cross-section of the sand dividing plate is an isosceles triangle with the two waist sides of the sand dividing plate facing left. The two groups of sand scraping plates are symmetrically inclined and arranged in an inverted triangle. The advantage of such a setting is that the sand dividing plate and the sand scraping plate can better spread the sand evenly, ensuring the uniformity of sand spreading. At the same time, when the two groups of sand scraping plates rotate towards the direction away from each other, the distance between the bottom end of the sand scraping plate and the road surface gradually decreases. In this way, it can be ensured that when the sand is pushed and leveled, as the sand scraping plate swings, the sand in contact with the sand scraping plate will become less and less, and the height of the sand will become lower and lower. In this way, it can be ensured that the sand scraping plate can always effectively push and level the sand, maximizing the uniformity and effect of sand fluctuation and leveling.

[0011] In summary, the technical effects and advantages of the present utility model are as follows:

[0012] 1. In the present utility model, the sand dividing plate is arranged to initially divide the sand discharged from the sand outlet pipe into two strands, and then the driving unit drives the two groups of sand scraping plates to alternately move away from or close to each other to push and level the two strands of sand towards the front and rear sides, thereby improving the uniformity of the sand distribution on the road surface. Finally, the paving plate is used to perform the final leveling operation on these sands, so as to ensure that the sand can be evenly spread and sown on the surface of the sealant, improving the effect of preventing the wheels from sticking to the sealant. And as the device moves for glue filling, the uniform sowing of the sand can be completed, thereby effectively improving the efficiency of highway crack sealing and maintenance work, shortening the road surface blocking time, and improving the traffic efficiency.

[0013] 2. In the present utility model, the driving assembly drives the two sand scraping plates to rotate horizontally in directions approaching or moving away from each other alternately, and at the same time, the triangular block and the rotating ring can drive the two sand scraping plates to rotate vertically in directions approaching or moving away from each other alternately, so that the uniformity of spreading and sowing the sand and soil can be greatly improved, and the effect of preventing the wheels from sticking to the caulking glue is effectively improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0022] Example 1

[0023] Please refer to Figures 1-5 a highway maintenance crack filling device shown in the figure, which includes a bottom plate 1. Four rollers 11 are fixedly installed at the four corners of the bottom of the bottom plate 1. A push handle 12 is fixedly connected to the top of the bottom plate 1. A glue tank 2 is fixedly connected to the top of the bottom plate 1. A glue outlet pipe 21 is communicated with the bottom of the glue tank 2. The bottom end of the glue outlet pipe 21 penetrates through the bottom of the bottom plate 1. A glue pump 22 is communicated with the glue outlet pipe 21. A cover plate 23 is connected to the top of the glue tank 2. A feed pipe 24 is communicated with the top of the cover plate 23. A motor 25 is fixedly connected to the top of the cover plate 23. A stirring rod is fixedly connected to the output shaft of the motor 25. The stirring rod is located inside the glue tank 2 to stir the crack filling glue to prevent the crack filling glue from solidifying. A sand hopper 3 is fixedly connected to the top of the bottom plate 1. A sand outlet pipe 31 is communicated with the bottom of the sand hopper 3. A plug is inserted at the bottom end of the sand outlet pipe 31. The bottom end of the sand outlet pipe 31 penetrates through the bottom of the bottom plate 1. A sand distributing plate 4 is fixedly connected to the bottom of the bottom plate 1. A sand leveling assembly 5 is arranged on the bottom plate 1. A leveling plate 6 is fixedly connected to the bottom of the bottom plate 1.

[0024] Refer to Figures 1-3 , the sand leveling assembly 5 includes two groups of sand scraping plates 51 movably arranged at the bottom of the bottom plate 1. The number of each group of sand scraping plates 51 is several and they are evenly distributed at equal intervals from left to right. The two groups of sand scraping plates 51 are staggered. The sand leveling assembly 5 further includes a driving unit 52. The driving unit 52 is used to push the two groups of sand scraping plates 51 to reciprocally move away from or close to each other to evenly stir the sand to the front and back sides.

[0025] Specifically, when the two groups of staggered sand scraping plates 51 alternately approach or move away from each other, the sand falling on the surface of the crack filling glue from the sand outlet pipe 31 can be evenly pushed to both sides, so that the subsequent leveling plate 6 can push these sands more evenly on the surface of the crack filling glue. In this way, the uniformity of sand spreading is ensured, effectively preventing the subsequent vehicle wheels from sticking and taking away the crack filling glue when passing over the surface of the crack filling glue, ensuring that the repair of the road surface crack will not be damaged and ensuring the safety of the road surface.

[0026] Refer to Figure 2 , 4With respect to 5, the driving unit 52 includes two rotating blocks 521 symmetrically and rotatably connected to the bottom of the bottom plate 1. Two fixing rods 522 are symmetrically and fixedly connected to the right side surfaces of the two rotating blocks 521. Two groups of sand scraping plates 51 are respectively fixedly connected to the bottoms of the two fixing rods 522. The driving unit 52 further includes two cylinders 523 symmetrically and fixedly connected to the top of the bottom plate 1. A driving member 524 is installed at the output ends of the two cylinders 523. The driving member 524 includes two inclined surfaces symmetrically arranged. The driving member 524 is located between the two fixing rods 522 and the two inclined surfaces are simultaneously in contact with the side surfaces of the two fixing rods 522. As the driving member 524 moves up and down, it can push the two fixing rods 522 to rotate in the direction of approaching or separating from each other.

[0027] Specifically, by pushing the driving member 524 to reciprocate up and down through the cylinder 523, the two fixing rods 522 can be pushed to rotate in the horizontal direction in the direction of approaching or separating from each other. In this way, the sand that is pushed and leveled by the two groups of sand scraping plates 51 is distributed in an arc shape, and the lengths of multiple channels of leveled sand gradually increase from left to right. As a result, when the multiple channels of sand are leveled by the spreading plate 6, they can be more evenly distributed on the surface of the caulking glue, further improving the effect and reliability of the sand spreading work, and improving the effect of preventing the caulking glue from adhering to the wheels.

[0028] Reference Figure 4 and Figure 5 The driving unit 52 further includes two groups of rotating rings 525 rotatably connected to the outer side surfaces of the two fixing rods 522. The number of each group of rotating rings 525 is equal to the number of each group of sand scraping plates 51. The tops of the two groups of sand scraping plates 51 are respectively fixedly connected to the bottoms of the two groups of rotating rings 525. The driving member 524 is composed of two groups of triangular blocks. The number of each group of triangular blocks is equal to the number of each group of rotating rings 525. The included angle between the inclined surfaces of several triangular blocks in each group and the horizontal plane gradually decreases from left to right. The inclined surfaces of the two groups of triangular blocks are respectively in contact with the outer circumferential surfaces of the two groups of rotating rings 525. The tops of the two groups of triangular blocks are fixedly connected with straight rods 526. The tops of the two groups of straight rods 526 penetrate through the top of the bottom plate 1 and are fixedly connected to the same pushing plate 527. The two groups of straight rods 526 are movably inserted into the bottom plate 1. The pushing plate 527 is fixedly connected to the output ends of the two cylinders 523.

[0029] Specifically, while pushing the two groups of sand scraping plates 51 to alternately rotate in the direction of approaching or separating from each other, the two groups of sand scraping plates 51 can be driven to alternately swing up and down in the vertical direction through the rotating rings 525, thereby further improving the effect and reliability of the sand spreading work.

[0030] Reference Figures 1-5 The cross-section of the sand scraping plate 51 is a rhombus, the cross-section of the sand dividing plate 4 is an isosceles triangle, and the two waist sides of the sand dividing plate 4 face left. The two groups of sand scraping plates 51 are symmetrically inclined and arranged in an inverted triangle.

[0031] Specifically, the sand distributing plate 4 and the sand scraping plate 51 can better spread the sand and soil evenly, ensuring the uniformity of sand and soil sowing. At the same time, when the two groups of sand scraping plates 51 rotate in the direction away from each other, the distance between the bottom end of the sand scraping plate 51 and the road surface gradually decreases. In this way, it can be ensured that when scraping and leveling the sand and soil, as the sand scraping plate 51 swings, the amount of sand and soil in contact with the sand scraping plate 51 will become less and less, and the height of the sand and soil will become lower and lower. In this way, it can be ensured that the sand scraping plate 51 can always effectively scrape and level the sand and soil, maximizing the uniformity and effect of scraping and leveling the sand and soil.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
