Description

Technical Field

[0001] The utility model relates to the technical field of road repair, in particular to a backfill structure for municipal road repair. Background Art

[0002] Municipal roads refer to roads with certain technical conditions and facilities within the city. They are one of the basic infrastructures of urban construction. During the use of roads, cracks often appear on the road surface. The existence of cracks will threaten the safety of roads or bridges. It is necessary to backfill them in layers with mud, cement and other materials with good stability, and then press and smooth the backfill material.

[0003] Patent document No. 202122704152.8 discloses a grouting device for repairing hollow drums of municipal roads, comprising a base plate, a support plate fixedly mounted on the left side of the upper surface of the base plate, and a barrel fixedly mounted on the right side of the upper surface of the base plate. The grouting device for repairing hollow drums of municipal roads is moved to a position to be grouted, so that the grouting pipe is located above the opened grouting hole.

[0004] However, the traditional way to repair cracks on municipal roads is for operators to manually fill cement or mud, infiltrate the mud into the gaps, and manually smooth the cement on the road surface. However, this operation method not only has high labor costs, but also takes a long time to repair. When filling the road cracks, it is easy to cause too much mud to be dumped, resulting in a waste of mud resources. Utility Model Content

[0005] The utility model discloses a backfill structure for repairing municipal roads, aiming to solve the problem that a traditional method for repairing cracks on municipal roads is that operators manually fill cement or mud, infiltrate the mud into the gaps, and manually smooth the cement on the road surface. However, such an operation method not only has high labor costs, but also takes a long time to repair. When filling the road gaps, it is easy to cause excessive dumping of mud, thereby resulting in a technical problem of waste of mud resources.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A backfill structure for municipal road repair, comprising an installation box, both outer walls of which are hinged with a same push rod, and further comprising:

[0008] Limiting mechanism: located at the bottom inner wall of the installation box, the limiting mechanism includes a mounting seat, a sleeve rod, a limiting hanging rod and a movable rod, a material storage barrel is arranged inside the mounting seat, a mounting plate and two fixed plates are arranged on the circumferential outer wall of the mounting seat, two ends of the sleeve rod penetrate through the outer walls of both sides of the limiting hanging rod, a limiting column is arranged between the two fixed plates, and two ends of the limiting column respectively penetrate through the outer walls of one side of the two fixed plates, two ends of the sleeve rod and two ends of the movable rod both penetrate through the circumferential outer wall of the limiting column, and the limiting hanging rod is clamped on the inner wall of the material storage barrel;

[0009] Material dumping mechanism: located on one outer wall of the installation box;

[0010] Stirring mechanism: located at the top of the pouring mechanism;

[0011] Mobile leveling mechanism: located at the bottom of the installation box.

[0012] The adoption of the above technical scheme can reduce the workload of operators. Specifically, when in use, the operator first hangs the limit hanging rod to the inner edge of the storage barrel and presses down the movable rod. At this time, a pulling force is generated to lock the sleeve rod, and the limit hanging rod can firmly lock the storage barrel. When the movable rod is lifted upward and perpendicular to the fixed plate, the pulling force becomes loose, and the limit hanging rod can be separated from the storage barrel. This working principle is consistent with the principle of lever. For example, the hook-shaped threaded buckle used in daily life can adjust the distance between the nut, the sleeve rod and the limit column according to the actual height of the storage barrel to control the required force. This structure is simple and easy to use, reduces the manpower burden, and can flexibly adjust and fix the storage barrel for a long time, avoiding the operator holding the storage barrel for a long time to fill the road cracks that need to be repaired with mud, thereby reducing the waste of mud resources.

[0013] In a preferred embodiment, the pouring mechanism includes a large gear and a small gear, and the circumferential outer wall of the mounting seat is fixedly connected to two mounting rods, one of the mounting rods is connected to an outer wall of one side of the large gear through a bearing, and the small gear is meshed with the large gear, and an outer wall of one side of the small gear is connected to a handle through a bearing, and an outer wall of the small gear away from the handle is connected to an outer wall of one side of the mounting box through a bearing.

[0014] When in use, first use the limiting mechanism to limit and fix the storage barrel to prevent the storage barrel from tipping out of the mounting base when tilting downward, and then turn the handle to drive the small gear to rotate. Due to the meshing action of the large gear and the small gear, the number of revolutions of the large gear on the output shaft of the small gear with fewer teeth is used to control the inclination angle of the mounting base according to the actual amount of mud in the storage barrel, thereby controlling the inclination angle of the storage barrel, thereby replacing the step of the operator holding the storage barrel, saving the operator's energy.

[0015] In a preferred embodiment, the stirring mechanism includes two support plates, the top outer walls of the two support plates are fixed with the same connecting plate by bolts, the bottom outer wall of the connecting plate is provided with a motor, and the output shaft of the motor is fixedly connected with a spiral stirring rod.

[0016] Start the motor, and the output shaft of the motor drives the spiral stirring rod to rotate, thereby driving the mud in the storage barrel to be stirred evenly in proportion to prevent the mud from solidifying if it remains stationary for a long time. The provided support plate is convenient for limiting and fixing the connecting plate. When the spiral stirring rod needs to be cleaned or repaired, it is only necessary to remove the bolts between the connecting plate and the support plate and the connecting plate, and the entire motor and the spiral stirring rod can be removed.

[0017] In a preferred solution, the movable grinding mechanism includes four mounting blocks, and the four mounting blocks are located on the bottom outer wall of the mounting box, wherein the same grinding roller is connected between two adjacent mounting blocks via a bearing.

[0018] When the mud fills the road cracks, the grinding roller is pushed to compact the road surface and smooth the mud on the road surface, thereby repairing the road cracks. At the same time, the grinding roller reduces friction with the road surface when moving and smoothing the mud, avoids high-intensity wear, and increases its service life.

[0019] As can be seen from the above, a backfill structure for municipal road repair includes an installation box, the two outer walls of the installation box are hinged with the same push rod, and also includes:

[0020] Limiting mechanism: located at the bottom inner wall of the installation box, the limiting mechanism includes a mounting seat, a sleeve rod, a limiting hanging rod and a movable rod, a material storage barrel is arranged inside the mounting seat, a mounting plate and two fixed plates are arranged on the circumferential outer wall of the mounting seat, two ends of the sleeve rod penetrate through the outer walls of both sides of the limiting hanging rod, a limiting column is arranged between the two fixed plates, and two ends of the limiting column respectively penetrate through the outer walls of one side of the two fixed plates, two ends of the sleeve rod and two ends of the movable rod both penetrate through the circumferential outer wall of the limiting column, and the limiting hanging rod is clamped on the inner wall of the material storage barrel;

[0021] Material dumping mechanism: located on one outer wall of the installation box;

[0022] Stirring mechanism: located at the top of the pouring mechanism;

[0023] Mobile leveling mechanism: located at the bottom of the installation box.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0030] The utility model discloses a backfill structure for municipal road repair, which is mainly used for repairing cracks on traditional municipal roads in which an operator manually fills cement or mud, infiltrates the mud into the gaps, and manually smoothes the cement on the road surface. However, such an operation method not only has high labor costs, but also takes a long time to repair. When filling the road gaps, it is easy to cause excessive dumping of mud, thereby resulting in a waste of mud resources.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A backfill structure for municipal road repair includes an installation box 1, the outer walls of both sides of the installation box 1 are hinged with the same push rod 4, and also includes:

[0032] Limiting mechanism: located at the bottom inner wall of the installation box 1, the limiting mechanism includes a mounting seat 13, a sleeve rod 16, a limiting hanging rod 15 and a movable rod 19. A storage barrel 12 is arranged inside the mounting seat 13, and a mounting plate 14 and two fixing plates 17 are arranged on the circumferential outer wall of the mounting seat 13. Both ends of the sleeve rod 16 penetrate the outer walls of both sides of the limiting hanging rod 15. A limiting column 18 is arranged between the two fixing plates 17, and both ends of the limiting column 18 penetrate the outer walls of one side of the two fixing plates 17 respectively. Both ends of the sleeve rod 16 and both ends of the movable rod 19 penetrate the circumferential outer wall of the limiting column 18, and the limiting hanging rod 15 is clamped on the inner wall of the storage barrel 12;

[0033] Material dumping mechanism: located on one side outer wall of the installation box 1;

[0034] Stirring mechanism: located at the top of the pouring mechanism;

[0035] Mobile leveling mechanism: located at the bottom of the installation box 1.

[0036] Among them, threads are provided in the middle of the sleeve rod 16 near both ends, which is convenient for use with the sleeve rod 16 through a nut, so as to adjust the distance between the sleeve rod 16 and the limiting column 18, and limit and fix the sleeve rod 16 on the limiting column 18.

[0037] During specific use, the mounting plate 14 is a "concave" shaped structure, and the fixing plate 17 is an "L" shaped structure. The mounting plate 14 with the "concave" shaped structure can play a certain limiting role on the limiting hanging rod 15 and the sleeve rod 16, and the fixing plate 17 with the "L" shaped structure facilitates the connection between the limiting column 18 and the movable rod 19.

[0038] Among them, the circumferential outer wall of the storage barrel 12 is fixedly connected with a first connecting pipe 5, one end of the first connecting pipe 5 is fixedly connected with a fixed box 6, and the bottom outer wall of the fixed box 6 is provided with four second connecting pipes 7 distributed at equal distances, and the second connecting pipe 7 passes through the outer wall of one side of the fixed box 6 and is threadedly connected with a slurry discharge joint 8, and the angle between the slurry discharge joint 8 and the horizontal plane is 25-30 degrees. This arrangement is convenient for pouring mud into the road gap to prevent mud from splashing back during vertical dumping and backfilling. When the storage barrel 12 is controlled by the limiting mechanism and the pouring mechanism, the mud in the storage barrel 12 flows out through the first connecting pipe 5 and is temporarily stored in the fixed box 6. The size of the slurry discharge joint 8 is changed according to the area of ​​the road to be repaired, and then the mud in the fixed box 6 flows into the road gap from the slurry discharge joint 8 on the second connecting pipe 7 for filling.

[0039] When the movable rod 19 is lifted upward and perpendicular to the fixing plate 17, the tension becomes loose, and the limit hanging rod 15 can be separated from the material storage barrel 12. This working principle is consistent with the lever principle. For example, the hook-shaped threaded buckle used in daily life can adjust the distance between the nut, the sleeve rod 16 and the limit column 18 according to the actual height of the material storage barrel 12 to control the force required for use. This structure is simple and easy to use, reduces the manpower burden, and can flexibly adjust and fix the material storage barrel 12 for a long time, avoiding the operator from holding the material storage barrel 12 for a long time to fill the road joint to be repaired with mud, thereby reducing the waste of mud resources.

[0040] Reference Figure 4 In a preferred embodiment, the pouring mechanism includes a large gear 20 and a small gear 21, and the circumferential outer wall of the mounting seat 13 is fixedly connected to two mounting rods, one of which is connected to an outer wall of one side of the large gear 20 through a bearing, and the small gear 21 is meshed with the large gear 20, and an outer wall of one side of the small gear 21 is connected to a handle 22 through a bearing, and an outer wall of the small gear 21 away from the handle 22 is connected to an outer wall of one side of the mounting box 1 through a bearing.

[0041] Specifically, when in use, the limiting mechanism is first used to limit and fix the storage barrel 12 to prevent the storage barrel 12 from tipping out of the mounting seat 13 when tilting downward, and then the handle 22 is turned to drive the pinion 21 to rotate. Due to the meshing action of the large gear 20 and the small gear 21, the number of revolutions of the large gear 20 on the output shaft engaged with the small gear 21 with a small number of teeth is used to control the inclination angle of the mounting seat 13 according to the actual amount of mud in the storage barrel 12, thereby controlling the inclination angle of the storage barrel 12, thereby replacing the step of the operator holding the storage barrel 12, saving the operator's energy.

[0042] Reference Figure 2 In a preferred embodiment, the stirring mechanism includes two support plates 9, the top outer walls of the two support plates 9 are fixed with the same connecting plate 3 by bolts, the bottom outer wall of the connecting plate 3 is provided with a motor 10, and the output shaft of the motor 10 is fixedly connected with a spiral stirring rod 11.

[0043] Specifically, the motor 10 is started, and the output shaft of the motor 10 drives the spiral stirring rod 11 to rotate, thereby driving the mud in the storage barrel 12 to be stirred evenly in proportion to prevent the mud from solidifying due to long-term static state. The provided support plate 9 is convenient for limiting and fixing the connecting plate 3. When the spiral stirring rod 11 needs to be cleaned or repaired, it is only necessary to remove the bolts between the connecting plate 3 and the support plate 9 to remove the entire motor 10 and the spiral stirring rod 11.

[0044] Reference Figure 1 In a preferred embodiment, the mobile grinding mechanism includes four mounting blocks, which are located on the bottom outer wall of the mounting box 1, and the same grinding roller 2 is connected between two adjacent mounting blocks through bearings.

[0045] Specifically, after the mud fills the road cracks, the grinding roller 2 is pushed to compact the road surface and smooth the mud on the road surface, thereby repairing the road cracks. At the same time, the grinding roller 2 reduces friction with the road surface when moving and smoothing the mud, avoids high-intensity wear, and increases its service life.

[0046] Working principle: When in use, the operator pushes the device to the designated road crack position that needs to be repaired through the push rod 4, and then fully stirs the mud in the storage barrel 12 through the stirring mechanism, and then hangs the limit hanging rod 15 to the inner edge of the storage barrel 12, and presses the movable rod 19 downward. At this time, a pulling force is generated and locked with the sleeve rod 16, and the limit hanging rod 15 can firmly lock the storage barrel 12. When the movable rod 19 is lifted upward and perpendicular to the fixed plate 17, the pulling force becomes loose, and the limit hanging rod 15 can be separated from the storage barrel 12. This working principle is consistent with the principle of leverage. For example, the hook-shaped threaded buckle used in daily life can adjust the distance between the nut, the sleeve rod 16 and the limit column 18 according to the actual height of the storage barrel 12 to control the force required for use.

[0047] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
