Description

Technical Field

[0001] The present application relates to the technical field of urban road engineering, and in particular to a road surface crack repairing device for urban road engineering. Background Art

[0002] Urban road engineering constitutes a key part of urban infrastructure construction. According to the function and grade of the road, it is subdivided into many types, including expressways, main roads, secondary roads and branch roads. Each type of road has its own specific standards and requirements in design and construction, but most of them include three main parts: roadbed, pavement and drainage system;

[0003] As the supporting structure of the road, the roadbed undertakes the important task of bearing the weight of the road and traffic load, while the pavement is the surface layer of the road, which directly bears the driving and wear of vehicles. With the continuous expansion of the scale of vehicles, the problem of road cracks has become increasingly prominent, which not only affects the aesthetics of the road, but more importantly, reduces the road's traffic capacity and safety. Therefore, in order to ensure the normal operation of the road and traffic safety, it is necessary to use pavement crack repair devices to repair pavement cracks in time.

[0004] For example, China's authorized publication number is CN 117364598 B, which discloses a road crack repair device for traffic engineering construction, which can complete the filling of deep and surface layers of cracks by simply moving the vehicle body along the general extension direction of the cracks, which is convenient and labor-saving.

[0005] However, most pavement crack repair devices cannot adapt to cracks of different depths, resulting in the accumulation of filling materials only in the shallower part of the cracks and failing to effectively penetrate to the bottom of the cracks. As a result, the gaps that are not fully filled are prone to become potential damage points during future use, affecting the use of the pavement and shortening the overall service life of the pavement. Summary of the invention

[0006] To this end, the present application provides a pavement crack repair device for urban road engineering to solve the problem that the existing repair cannot adapt to cracks of different depths, resulting in the accumulation of filling materials only in the shallower part of the crack and unable to effectively penetrate to the bottom of the crack.

[0007] In order to achieve the above objectives, this application provides the following technical solutions:

[0008] A road crack repair device for urban road engineering, comprising a mounting base, a material delivery hose and a mounting column, wherein a moving wheel is arranged on the outer side of the lower end of the mounting base, and a reinforcement ring is fixedly installed on the outer side of the upper end of the mounting base, a storage assembly is arranged inside the reinforcement ring, and a pump body is installed on the left side of the upper end of the reinforcement ring;

[0009] The output end of the pump body is connected to a feeding hose, and the outer side of the lower end of the feeding hose is connected to a connecting joint, and a nozzle is installed on the outer side of the lower end of the connecting joint;

[0010] A mounting column is installed on the inner side of the connecting joint, and a limiting rod is arranged inside the mounting column, a spring located in the mounting column is sleeved on the outer side of the limiting rod, and a guide tube is arranged on the outer side of the lower end of the limiting rod.

[0011] Furthermore, the storage assembly includes a liquid storage tank, a tank cover, a driving motor, a stirring rod and a liquid inlet pipe. The liquid storage tank is installed on the outer side of the upper end of the mounting base and is located on the inner side of the reinforcement ring. The tank cover is fixed to the outer side of the upper end of the liquid storage tank by screws, and a driving motor is arranged in the middle of the upper end of the tank cover.

[0012] Furthermore, the output end of the driving motor is connected to a stirring rod rotating in the liquid storage tank, and a pipeline communicating with the pump body is penetrated through the lower left end of the liquid storage tank.

[0013] Furthermore, a fixing bolt is provided through the outer side of the connection between the connecting joint and the nozzle, and a sealing ring is provided on the outer side of the upper end of the nozzle and the inner side of the connecting joint.

[0014] Furthermore, the upper end of the mounting column extends to the inside of the lower end of the material delivery hose, and a limiting groove is provided on the inner wall of the mounting column.

[0015] Furthermore, the limiting rod and the guide tube are connected to the mounting column in a sliding manner, and connecting protrusions are fixedly installed on the outer sides of the front and rear ends of the mounting column, and the connecting protrusions are adapted to the size of the limiting grooves.

[0016] Furthermore, a fixing plate is integrally fixedly installed on the outer side of the left end of the mounting base, and the nozzle passes through the interior of the fixing plate.

[0017] Furthermore, a connecting tube is arranged on the outer side of the lower end of the fixing plate, and electric hydraulic rods located on the outer side of the lower end of the fixing plate are arranged on the outer sides of both left and right ends of the connecting tube.

[0018] Furthermore, a vibrator is arranged on the right side of the lower end of the connecting tube, and a grounding plate is arranged inside the lower end of the connecting tube, and the upper and lower ends of the connecting tube are both open.

[0019] Furthermore, the upper end of the connecting tube extends to the inside of the lower end of the connecting tube, and a prefabricated groove matching the connecting tube is opened through the inside of the fixing plate.

[0020] Compared with the prior art, this application has at least the following beneficial effects:

[0021] 1. Align the nozzle with the crack by moving the overall position. When the nozzle is aligned with the crack, rotate the guide tube extending outside the lower end of the nozzle counterclockwise to drive the connecting protrusion to rotate inside. After rotating 90°, the connecting protrusion moves to the end. At this time, the connecting protrusion loses its limiting effect. The spring originally in a compressed state recovers its deformation, exerting a downward force on the guide tube and the limiting rod, thereby driving the limiting rod, the guide tube and the connecting protrusion to slide downward inside the mounting column, so that the guide tube can be inserted into the bottom of the gap and tightly connected to the bottom of the gap under the action of the spring, adapting to cracks of different depths.

[0022] 2. The filling material in the liquid storage tank flows into the feeding hose through the pipeline and the pump body, and then flows into the connecting joint and the nozzle in turn, and flows out from the nozzle to repair the crack. At the same time, the filling material effectively penetrates to the bottom of the crack along the guide pipe inserted into the crack, so as to fully fill the crack;

[0023] 3. Use a vibrator to drive the connecting tube and the grounding plate to vibrate, so as to vibrate the road surface around the crack to improve the tightness of the connection between the filling material and the road surface. At the same time, it is convenient for the filling material to flow into smaller cracks, so as to further improve the repair effect and increase the overall service life of the road surface.

[0033] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0034] like Figures 1 to 6 As shown, a road surface crack repairing device for urban road engineering in an embodiment of the first aspect of the present application comprises: a mounting base 1, a material delivery hose 11 and a mounting column 15, a moving wheel 2 is arranged on the outer side of the lower end of the mounting base 1, and a push rod 3 is welded and fixed on the right side of the upper end of the mounting base 1, so that the push rod 3 can be used to push the whole to move, thereby facilitating the moving of the material to a designated position under the action of the moving wheel 2;

[0035] A reinforcement ring 4 is fixedly mounted on the outer side of the upper end of the mounting base 1, and a storage assembly is arranged inside the reinforcement ring 4. The storage assembly includes a liquid storage tank 5, a tank cover 6, a drive motor 7, a stirring rod 8 and a liquid inlet pipe 9. The liquid storage tank 5 is mounted on the outer side of the upper end of the mounting base 1 and is located on the inner side of the reinforcement ring 4. The tank cover 6 is fixedly mounted on the outer side of the upper end of the liquid storage tank 5 by screws. A drive motor 7 is arranged in the middle of the upper end of the tank cover 6. The output end of the drive motor 7 is connected to the stirring rod 8 rotating in the liquid storage tank 5.

[0036] The reinforcement ring 4 plays a good installation role for the liquid storage tank 5. Before use, the filling material required to repair the cracks is injected into the liquid storage tank 5 through the liquid inlet pipe 9, and the drive motor 7 is started, so that the drive motor 7 drives the stirring rod 8 to rotate inside the liquid storage tank 5. At this time, the stirring rod 8 stirs the filling material, which can effectively prevent the filling material from solidifying in the liquid storage tank 5. After the overall use is completed, the tank cover 6 can be disassembled by rotating the screws, which is convenient for cleaning the inside of the liquid storage tank 5.

[0037] The outer side of the lower end of the material delivery hose 11 is connected to the connecting joint 12, and the outer side of the lower end of the connecting joint 12 is installed with a nozzle 13. The outer side of the connection between the connecting joint 12 and the nozzle 13 is penetrated by a fixing bolt 14, and the outer side of the upper end of the nozzle 13 and the inner side of the connecting joint 12 are both provided with a sealing ring 28. The nozzle 13 is aligned and installed on the outer side of the lower end of the connecting joint 12. At this time, the lower end of the guide tube 18 extends and penetrates the inside of the nozzle 13, so that the sealing ring 28 installed on the outer side of the upper end of the nozzle 13 is in contact with the lower end of the connecting joint 12, thereby improving the tightness of the connection between the connecting joint 12 and the nozzle 13. Then, the fixing bolt 14 is rotated and inserted into the inside of the connecting joint 12 and the nozzle 13 in turn, so that the nozzle 13 can be fixedly installed on the outer side of the lower end of the connecting joint 12;

[0038] After the assembly is completed, the connecting joint 12 is rotated and installed on the outer side of the lower end of the material delivery hose 11, so that the connecting joint 12 and the material delivery hose 11 are threadedly connected, and the sealing ring 28 installed on the inner side of the connecting joint 12 contacts the lower end of the material delivery hose 11, thereby improving the tightness of the connection between the connecting joint 12 and the material delivery hose 11. At the same time, the material delivery hose 11, the connecting joint 12 and the nozzle 13 are connected to ensure the smooth flow of the filling material; a fixing plate 20 is integrally fixedly installed on the outer side of the left end of the mounting base 1, and the lower end of the nozzle 13 is inserted into the interior of the fixing plate 20, and the fixing ring plate 26 is fixedly installed on the outer side of the left end of the reinforcement ring 4 with screws, so that the fixing ring plate 26 contacts the outer wall of the material delivery hose 11, so as to fix the material delivery hose 11. After fixing, there is a certain height difference between the lower end of the nozzle 13 and the road surface, so as to prevent the nozzle 13 from being damaged by the wear of the road surface during the movement.

[0039] A mounting column 15 is installed on the inner side of the connecting joint 12, and a limiting rod 16 is provided inside the mounting column 15, a spring 17 located inside the mounting column 15 is sleeved on the outer side of the limiting rod 16, and a flow guide tube 18 is provided on the outer side of the lower end of the limiting rod 16. The mounting column 15 plays a good installation and limiting role for the limiting rod 16 and the flow guide tube 18. At the same time, a sealing structure is provided at the connection between the upper end of the mounting column 15 and the limiting rod 16 to prevent the filling material from entering the mounting column 15. The upper end of the connecting joint 12 extends to the lower end of the material delivery hose 11, and a limiting groove 19 is provided on the inner wall of the mounting column 15. The limiting rod 16 and the flow guide tube 18 are both connected to the mounting column 15 in a sliding manner, and connecting protrusions 27 are fixedly installed on the outer sides of the front and rear ends of the mounting column 15, and the connecting protrusions 27 are adapted to the size of the limiting groove 19;

[0040] The nozzle 13 is aligned with the crack by moving the overall position. When the nozzle 13 is aligned with the crack, the guide tube 18 extending outside the lower end of the nozzle 13 is rotated counterclockwise, so that the guide tube 18 drives the connecting protrusion 27 to rotate inside the limiting groove 19. After rotating 90 degrees, the connecting protrusion 27 moves to the end of the limiting groove 19. At this time, the limiting groove 19 loses its limiting effect on the connecting protrusion 27. The spring 17, which was originally in a compressed state, recovers its deformation and exerts a downward force on the guide tube 18 and the limiting rod 16, thereby driving the limiting rod 16, the guide tube 18 and the connecting protrusion 27 to slide downward inside the mounting column 15, so that the guide tube 18 can be inserted into the bottom of the gap and tightly connected to the bottom of the gap under the action of the spring 17, so as to adapt to cracks of different depths.

[0041] A pump body 10 is installed on the left side of the upper end of the reinforcement ring 4, and a pipe connected to the pump body 10 is penetrated through the lower left end of the liquid storage tank 5. A material delivery hose 11 is connected to the output end of the pump body 10. The solenoid valves on the outside of the pump body 10 and the material delivery hose 11 are started to make the filling material in the liquid storage tank 5 flow into the material delivery hose 11 through the pipe and the pump body 10, and flow into the connecting joint 12 and the nozzle 13 in turn, and flow out from the nozzle 13, so as to repair the crack. At the same time, the filling material effectively penetrates to the bottom of the crack along the guide tube 18 inserted into the crack, so as to fully fill the crack.

[0042] A connecting tube 21 is provided on the outer side of the lower end of the fixing plate 20, and electric hydraulic rods 22 are provided on the outer sides of the left and right ends of the connecting tube 21, and are located on the outer side of the lower end of the fixing plate 20. A vibrator 23 is provided on the right side of the lower end of the connecting tube 21, and a grounding plate 24 is provided in the lower end of the connecting tube 21. The upper and lower ends of the connecting tube 21 are both open, and the upper end of the connecting tube 21 extends to the lower end of the connecting tube 21. A prefabricated groove 25 adapted to the connecting tube 21 is provided through the interior of the fixing plate 20, and the prefabricated groove 25 serves as a limit for the connecting tube 21 to ensure the stability of the movement of the connecting tube 21.

[0043] The nozzle 13 is located inside the connecting tube 21 during installation. When the guide tube 18 is rotated and inserted into the crack, the electric hydraulic rod 22 is started to extend the electric hydraulic rod 22 and drive the connecting tube 21 to move downward. At this time, the upper end of the connecting tube 21 slides in the prefabricated groove 25 until the lower end of the connecting tube 21 and the grounding plate 24 are in contact with the road surface. When the nozzle 13 and the mounting base 1 are repairing the road surface, the vibrator 23 is started so that the vibrator 23 can drive the connecting tube 21 and the grounding plate 24 to vibrate, so as to vibrate the road surface around the crack, so as to improve the tightness of the connection between the filling material and the road surface, and at the same time, facilitate the filling material to flow into smaller cracks, so as to further improve the repair effect and increase the overall service life of the road surface. At the same time, the grounding plate 24 on the right side can scrape off excess filling material when moving.

[0044] The connecting tube 21, the nozzle 13 and the guide tube 18 can be retracted by performing the reverse operation according to the overall steps to avoid affecting the overall movement.

[0045] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
