Description

Technical Field

[0001] The invention relates to the technical field of road repair, and in particular to a road crack repairing device with continuous material feeding. Background Art

[0002] As roads are used, cracks often appear on the surface or inside of roads. There are many reasons for the formation of road cracks, such as load-type cracks, temperature cracks, and foundation settlement cracks. The existence of road cracks will affect the service life of the road and endanger driving safety. Therefore, during the road maintenance process, it is necessary to pay attention to the remedial work of cracks to ensure the safety and stability of the road.

[0003] In order to facilitate the repair of road cracks, the prior art often uses a road crack repair machine, which mainly includes a base plate, rollers, a storage tank arranged on the base plate, an injection pipe connected to the storage tank, and a cleaning component arranged under the base plate. During repair, the base plate is pushed to move along the length direction of the road crack, and the cleaning component located under the base plate cleans impurities such as stones and mud in the crack, and then the repair material is injected into the crack through the injection pipe. The repair material adheres to the road raw material, and the road crack is repaired after cooling.

[0004] Due to the adhesion of the repair material, part of the repair material adheres to the inner wall of the storage tank and the discharge port during the forward movement of the repair machine. If the material is not discharged in time, the repair material on the inner wall will be deposited and cannot be utilized. The adhesion and accumulation of the repair material at the discharge port may cause blockage, resulting in the inability to discharge the repair material and the failure to inject the repair material into some cracks. In addition, blockage at the discharge port will cause a backlog of repair material in the storage tank, causing more material to adhere to the inner wall of the storage tank, resulting in incomplete utilization of the repair material and poor repair effect.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] like Figure 1 , Figure 2 , Figure 4 As shown, the present invention provides a road crack repairing device with continuous material discharge, comprising a base 1, a material storage tank 2 is movably mounted on the base 1, a material feed port 3 is arranged on the material storage tank 2, a material discharge port 4 is arranged at the bottom of the material storage tank 2, a material injection pipe 5 is installed below the base 1, and the material discharge port 4 is connected to the material injection pipe 5;

[0048] A rotary drive structure is installed outside the storage tank 2, and the rotary drive structure can drive the storage tank 2 to rotate around itself;

[0049] A Y-shaped stainless steel scraper 12 is installed inside the storage tank 2, and a movable rod 13 is connected to the Y-shaped stainless steel scraper 12. The movable rod 13 extends out of the top of the storage tank 2 and is connected to a lifting mechanism 11. The lifting mechanism 11 drives the Y-shaped stainless steel scraper 12 to rise and fall along the side wall of the storage tank 2;

[0050] The edge of the Y-shaped stainless steel scraper 12 contacts the inner wall of the storage tank 2. When the storage tank 2 rotates, the Y-shaped stainless steel scraper 12 scrapes off the repair material on the inner wall of the storage tank 2 at its height along the circumferential direction.

[0051] A power delivery cabin 15 is installed at the discharge port 4, and an auger 16 is installed in the power delivery cabin 15. When the storage tank 2 rotates, the auger runs and continuously drives the repair material to be discharged.

[0052] In the present invention, the process of cleaning the material in the storage tank 2 and the process of unloading are constructed into a linkage relationship. A Y-shaped stainless steel scraper 12 is installed inside the storage tank 2. The edge of the Y-shaped stainless steel scraper 12 contacts the inner wall of the storage tank 2. A power transmission cabin 15 is installed at the discharge port 4. A screw 16 is installed in the power transmission cabin 15. When the rotary drive structure drives the storage tank 2 to rotate, the Y-shaped stainless steel scraper 12 circumferentially scrapes off the repair material attached to the storage tank 2 at its height, and the height of the Y-shaped stainless steel scraper 12 is adjusted by the lifting mechanism 11 to clean the material in the storage tank 2. The repair materials on the inner wall of the tank 2 at different heights are scraped off. At the same time, the rotation of the storage tank 2 drives the auger 16 to rotate, and the rotation of the auger 16 drives the repair materials to continuously discharge, so as to avoid the situation where the repair materials are blocked at the discharge port and cannot be discharged. For the repair materials adhered to the inner wall of the storage tank, on the one hand, the continuous discharge process reduces the adhesion of the repair materials to the inner wall of the storage tank 2 to a certain extent. On the other hand, the Y-shaped stainless steel scraper 12 can scrape off a small amount of repair materials adhered to the inner wall of the storage tank 2, thereby improving the utilization rate of the repair materials and further improving the repair quality.

[0053] A lifting mechanism 11 for driving the Y-shaped stainless steel scraper 12 to lift and lower is provided on the top of the storage tank 2, and a power transmission cabin 15 is provided at the bottom thereof. In order to drive the storage tank 2 to rotate, the present invention designs a rotary drive structure on the side of the storage tank 2. Specifically, the rotary drive structure includes meshing teeth 8 installed on the outer periphery of the storage tank 2, and a double-axis motor 9 is installed on the base 1 near the storage tank 2. A first gear 10 is installed on one of the shaft ends of the double-axis motor 9, and the first gear 10 is meshed with the meshing teeth 8. The double-axis motor 9 drives the first gear 10 to rotate, and the first gear 10 drives the meshing teeth 8 to rotate, so that the storage tank 2 rotates synchronously.

[0054] like Figure 3As shown, the Y-shaped stainless steel scraper 12 can scrape off the repair material attached to the inner wall of the storage tank 2 at different heights under the drive of the lifting mechanism 11. Therefore, the lifting mechanism 11 needs to drive the Y-shaped stainless steel scraper 12 to perform vertical lifting movement along the inner wall of the storage tank 2. In order to drive the Y-shaped stainless steel scraper 12 to vertically lift along the inner wall of the storage tank 2, the lifting mechanism 11 in the present invention includes a threaded shaft 110 installed at one end of the dual-axis motor 9, and a threaded sleeve installed on the threaded shaft 110. 111, a connecting rod 112 connected to the side of the threaded sleeve 111, a lifting rod 113 installed on the connecting rod 112, a linkage rod 114, a guide shaft 115, and a movable sleeve 116, wherein the guide shaft 115 is installed on the base 1, the movable sleeve 116 is movably sleeved on the guide shaft 115, the end of the connecting rod 112 away from the threaded sleeve 111 is connected to the movable sleeve 116, one end of the linkage rod 114 is connected to the lifting rod 113, and the other end is connected to the movable rod 13;

[0055] The dual-axis motor 9 drives the threaded shaft 110 to rotate, and the threaded shaft 110 and the threaded sleeve 111 are threadedly matched to drive the threaded sleeve 111 to rise and fall, and the threaded sleeve 111 drives the connecting rod 112, the lifting rod 113, and the linkage rod 114 to rise and fall, and the movable rod 13 and the Y-shaped stainless steel scraper 12 are synchronously followed to rise and fall, wherein the guide rod 115 can prevent the threaded shaft 110 from rotating through the threaded sleeve 111, the lifting rod 113, the linkage rod 114, and the movable rod 13 to drive the Y-shaped stainless steel scraper 12 to rotate around the threaded shaft 110 as the center, thereby failing to achieve the purpose of lifting the Y-shaped stainless steel scraper 12 in the storage tank 2, the threaded shaft 110 makes the Y-shaped stainless steel scraper 12 move up and down, the guide rod 115 can fix the lifting direction of the Y-shaped stainless steel scraper 12, and the combined use of the threaded shaft 110 and the guide rod 115 can realize the lifting of the Y-shaped stainless steel scraper 12 in the storage tank 2.

[0056] Based on the above, it can be concluded that one end of the dual-axis motor 9 is connected to the first gear 10 to drive the storage tank 2 to rotate, and the other end is connected to the threaded shaft 110 to drive the Y-shaped stainless steel scraper 12 to rise and fall. Therefore, the dual-axis motor 9 should be vertically installed on the base 1. In order to be able to vertically install the dual-axis motor 9 on the base 1, a fixed seat 14 is installed on the base 1, and the dual-axis motor 9 and the guide shaft 115 are installed on the fixed seat 14. A circular through hole is opened on the fixed seat 14. The end of the dual-axis motor 9 passes through the circular through hole and is connected to the first gear 10. At this time, the first gear 10 can rotate in the horizontal direction, thereby facilitating the rotation of the meshing teeth 8.

[0057] like Figure 1As shown, the rotation of the first gear 10 drives the storage tank 2 to rotate, and the rotation of the storage tank 2 drives the auger 16 in the power transmission cabin 15 to rotate. In order to be able to drive the auger 16 to rotate by the rotation of the storage tank 2, a first bevel gear 17 is installed at the end of the power transmission cabin 15, and the shaft end of the auger 16 is connected to the first bevel gear 17. A second bevel gear 18 is circumferentially installed on the outer wall of the end of the storage tank 2 close to the discharge port 4. The first bevel gear 17 is meshed with the second bevel gear 18. When the storage tank 2 rotates, the second bevel gear 18 rotates accordingly, and the second bevel gear 18 drives the first bevel gear 17 to rotate, and the first bevel gear 17 drives the auger 16 to rotate. The rotation of the auger 16 drives the repair material to be continuously discharged;

[0058] Since the power delivery cabin 15 is connected to the discharge port 4, the rotation of the storage tank 2 will drive the power delivery cabin 15 to rotate. In order to prevent the power delivery cabin 15 from rotating, a first bearing 19 is installed on the inner wall of the discharge port 4. The power delivery cabin 15 is connected to the discharge port 4 through the first bearing 19. The first bearing 19 includes an inner ring and an outer ring. The inner wall of the discharge port 4 is connected to the outer ring of the first bearing 19, and the power delivery cabin 15 is connected to the inner ring of the first bearing 19. Therefore, when the storage tank 2 rotates, it will not drive the power delivery cabin 15 to rotate;

[0059] The repair material enters the power conveying cabin 15 from the discharge port 4, and is then conveyed into the injection pipe 5 through the auger 16 in the power conveying cabin 15. In order to convey the repair material into the injection pipe 5, the power conveying cabin 15 is connected to the injection pipe 5 at the end away from the first bevel gear 17. When the storage tank 2 rotates, the second bevel gear 18 drives the first bevel gear 17 to rotate, and the second bevel gear 18 drives the auger 16 to rotate. The rotation of the auger 16 conveys the repair material to the injection pipe 5.

[0060] In order to further prevent the repair material from being blocked in the injection pipe 5, the power transmission cabin 15 can be directly designed as an inclined cabin, the meshing relationship between the first bevel gear 17 and the second bevel gear 18 remains unchanged, and the discharge end of the auger 16 can directly discharge the material, which can not only reduce the discharge path and improve the discharge effect, but also prevent blockage.

[0061] The storage tank 2 is installed on the base 1, and the crack is located on the ground. In order to inject the repair material into the crack through the injection pipe 5, an opening is provided on the base 1 at a position opposite to the storage tank 2, and the bottom of the storage tank 2 passes through the opening. At this time, the discharge port 4, the power transmission cabin 15, the injection pipe 5 and other components located at the bottom of the storage tank 2 are all located below the base 1, thereby facilitating the transportation of the repair material into the crack.

[0062] The storage tank 2 is arranged on the base 1, and a repair material is installed inside the storage tank 2. When the first gear 10 drives the storage tank 2 to rotate, the friction between the storage tank 2 and the base 1 and the gravity of the storage tank 2 and the repair material make it difficult for the storage tank 2 to reach an ideal rotation speed. In order to help the first gear 10 drive the storage tank 2 to rotate, an annular convex strip 6 is installed circumferentially on the outer wall of the storage tank 2, and a plurality of arc-shaped groove seats 7 are installed on the base 1 along the circumference of the storage tank 2. The annular convex strip 6 is at least partially movably installed in the arc-shaped groove seat 7, and the annular convex strip 6 is away from the surface of the base 1. The arc-shaped groove seat 7 raises the storage tank 2 through the annular convex strip 6, and drives the gear 10 to rotate through the dual-axis motor 9, thereby driving the storage tank 2 to rotate. When the storage tank 2 is lifted, its bottom does not contact the base 1, reducing the friction between the storage tank 2 and the base 1, making it convenient for the dual-axis motor 9 to drive the storage tank 2 to rotate. Figure 5 As shown, in order to further reduce friction, a number of movable balls 31 can be installed on the inner wall of the arc groove seat 7. When the annular convex strip 6 rotates, the annular convex strip 6 slides in contact with the balls 31 in the arc groove seat 7, thereby further helping the storage tank 2 to rotate.

[0063] like Figure 1 , Figure 2 As shown, impurities such as stones and mud often exist in the cracks on the ground. If they are not removed, it will affect the adhesion of the repair material to the raw materials of the road surface. In order to clean it before injecting the repair material, a second gear 20 is installed on the base 1, and a rotating shaft 21 is installed on the side of the second gear 20. The rotating shaft 21 passes through the bottom of the base 1 and is connected to a cleaning brush 22, wherein the second gear 20 is meshed with the first gear 10, that is, when the first gear 10 rotates, it will drive the storage tank 2 and the second gear 20 to rotate at the same time. When driving the second gear 20 to rotate, the second gear 20 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the cleaning brush 22 to rotate. The rotating action of the cleaning brush 22 cleans the impurities in the cracks.

[0064] The cracks usually have a certain degree of size. When the cleaning brush 22 rotates for cleaning, it is difficult to sweep away the impurities on the inner edge of the cracks. In order to further clean the impurities in the cracks, an air pump 23 is installed in the base 1. An air outlet pipe 24 is installed at the end of the air pump 23. The end of the air outlet pipe 24 away from the air pump 23 is connected to a blowing pipe 25. The blowing pipe 25 passes through the bottom of the base 1. The blowing pipe 25 is arranged between the cleaning brush 22 and the injection pipe 5. The blowing port of the blowing pipe 25 is facing the middle of the crack. After the cleaning brush 22 sweeps away most of the impurities in the cracks, the blowing pipe 25 blows air forward toward the middle of the crack to blow away the impurities on the inner edge of the crack. The cleaning brush 22 and the blowing pipe 25 combination cleans the impurities in the cracks, making it easier for the repair material to bond with the raw materials of the road surface.

[0065] The cracks on the ground may have different depths. If the cleaning brush 22 and the air blow pipe 25 are far away from the bottom of the crack, it is difficult to clean the impurities in the crack. In order to clean the impurities in the crack, the cleaning brush 22 and the air blow pipe 25 are set to a structure with an adjustable distance from the crack. For this purpose, a cylinder 26 is installed inside the base 1. The driving end of the cylinder 26 is connected to a limit plate 27. A second bearing 28 is sleeved on the rotating shaft 21. One end of the limit plate 27 is connected to the second bearing 28, and the other end is connected to the air blow pipe 25. The cylinder 26 drives The limit plate 27 moves up and down to drive the cleaning brush 22 and the air pipe 25 to move up and down. The limit plate 27 fixes the cleaning brush 22 on the base plate 1 through the second bearing 28, and adjusts the height of the cleaning brush 22 and the air pipe 25 from the crack by adjusting the height of the limit plate 27. During the up and down adjustment process, the second gear 20 needs to remain engaged with the first gear 10, thereby driving the cleaning brush 22 to continue to rotate. In order to ensure that the second gear 20 can always engage with the first gear 10 during the up and down adjustment process, the thickness of the second gear 20 should be thick enough.

[0066] During the crack repair process, the device needs to move along the length of the crack. In order to facilitate the movement of the device, a handle 29 is installed on the base 1, and universal wheels 30 arranged in a rectangular array are installed at the bottom of the base 1. The staff drags the entire device through the handle 29 and the universal wheels 30.

The protection scope of the present application is defined by the claims.
