Description

Technical Field

[0001] This application relates to the field of road construction equipment technology, and in particular to a grouting device for cement-stabilized crushed stone base road construction. Background Technology

[0002] As the core load-bearing layer in the road structure system, the construction quality of cement-stabilized crushed stone base course directly affects the load-bearing performance and driving safety of the road during its service life. In actual engineering, although traditional processes such as paving and compaction have formed standardized construction procedures, the base course is prone to substandard compaction or local loosening due to factors such as geological conditions and mechanical operations. Therefore, grouting is required to improve the strength of the subgrade.

[0003] Grouting equipment is mainly divided into two types according to application scenarios and operational needs: handheld grouting machines and vehicle-mounted grouting machines. Vehicle-mounted grouting machines rely on the vehicle's power system and have the advantages of large-capacity material storage and long-distance transportation. They are often used for the repair of large-area basement defects. Handheld grouting machines are characterized by their lightness and flexibility and are suitable for precise grouting operations in narrow spaces or localized locations. The two complement each other and together meet the diverse needs of road maintenance projects.

[0004] When using existing handheld grouting machines, the internal mixing mechanism of the storage tank is designed in a simple way, which can only achieve unidirectional rotation and mixing. This makes it difficult for cement-based grout to form a three-dimensional mixing effect. After a long period of standing, the denser aggregates sink, causing segregation and imbalance of the water-cement ratio of the grout. Ultimately, this results in insufficient grouting strength and uneven setting, which affects the quality of the road base after grouting. Utility Model Content

[0005] The purpose of this application is to address the problem that the mixing effect of grout inside the storage tank of existing handheld grouting machines is insufficient, which affects the quality of the road base. This application provides a grouting device for cement-stabilized crushed stone road construction.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A grouting device for cement-stabilized crushed stone base road construction includes a base plate, with casters installed at all four corners of the lower end of the base plate. A support plate is fixed to the upper end of the base plate, and a handrail is fixed to the upper end of the support plate. A controller is fixed to the side of the support plate. A storage tank is fixed to the upper end of the base plate, and a cover plate is installed on the upper end of the storage tank. A pump is fixed to the side of the storage tank, with the inlet end of the pump connected to the storage tank. A guide pipe is fixed to the outlet end of the pump, and a grouting gun is fixed to the end of the guide pipe away from the pump. A feed pipe is fixed to the storage tank. A material leveling structure is provided between the cover plate and the storage tank. An anti-drying structure is provided at the upper end of the base plate.

[0008] By adopting the above technical solution, when using the grout, pour the grout into the storage tank, activate the uniformity structure to improve the uniformity of the grout, push the grouting device to the position where grouting is needed, and the operator holds the grouting gun towards the position where grouting is needed, and turns on the extraction pump to achieve grouting. After grouting is completed, put the grouting gun into the anti-drying structure to prevent drying, and then push the grouting device to the next position where grouting is needed.

[0009] Furthermore, the uniform material structure includes a drive motor fixed to the upper end of the cover plate, the output end of the drive motor extending through the cover plate and rotatably connected to the cover plate, a first stirring shaft fixed to the output end of the drive motor, a plurality of first stirring blades fixed on the first stirring shaft, and a plurality of second stirring shafts provided at the lower end of the cover plate, a plurality of second stirring blades fixed on the second stirring shafts.

[0010] By adopting the above technical solutions, the uniform material structure can play a role in uniform material distribution, thereby ensuring the quality of grouting.

[0011] Furthermore, the first and second stirring blades are staggered.

[0012] By adopting the above technical solution, the staggered arrangement can avoid mutual interference and improve the uniformity of materials.

[0013] Furthermore, a drive gear is fixed on the first agitator shaft, a gear ring is rotatably connected inside the cover plate, and a driven gear is fixed at the upper end of the second agitator shaft. The driven gear meshes with both the drive gear and the gear ring.

[0014] By adopting the above technical solution, the driving gear works in conjunction with the gear ring to make the driven gear rotate, thereby achieving a transmission function.

[0015] Furthermore, a connecting frame is fixed on the first agitator shaft, and the connecting frame is rotatably connected to the driven gear.

[0016] By adopting the above technical solution, the connecting frame is used to support the drive gear and the second agitator shaft.

[0017] Furthermore, a crossbar is fixed to the lower end of the first stirring shaft, and a vertical rod is fixed to the end of the crossbar away from the first stirring shaft. A scraper strip is fixed to the side of the vertical rod. The scraper strip is an elastic rubber strip and is in contact with the inner wall of the storage tank.

[0018] By adopting the above technical solution, the first stirring shaft drives the scraper to rotate, which can reduce the material adhesion to the inner wall of the storage tank and improve the mixing uniformity.

[0019] Furthermore, the anti-drying structure includes a water storage tank fixed to the upper end of the base plate, a drain pipe fixed to the water storage tank, a sealing cap installed on the drain pipe, and an mounting plate fixed to the upper end of the water storage tank, with mounting holes provided on the mounting plate.

[0020] By adopting the above technical solution, after grouting, the grouting gun is inserted into the installation hole, so that the discharge head of the grouting gun enters the water storage tank and is soaked in water, which can effectively reduce the coagulation of grout at the discharge head.

[0021] Furthermore, a retaining rubber ring is fixed inside the mounting hole, and the retaining rubber ring is an elastic rubber ring.

[0022] By adopting the above technical solution, the grouting gun is inserted into the fixed rubber ring, which can restrict the grouting gun to a certain extent.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. In this application, after adding materials into the storage tank, the drive motor is turned on, and the first stirring shaft drives the first stirring blade to perform basic stirring. At the same time, a second stirring shaft and a second stirring blade, which can rotate on their own axis and revolve around the first stirring shaft, are used to form a three-dimensional stirring field. This field can perform multi-dimensional shearing, tumbling and kneading of the grout, so that the cement, aggregate, additives and other components can be fully mixed, effectively suppressing the sedimentation and stratification phenomenon, ensuring that the grouting slurry always maintains uniform and stable physical properties, and significantly improving the quality and durability of road base repair.

[0025] 2. In this application, during the intervals or after the grouting operation, the grouting gun is inserted into the fixed rubber ring, so that the discharge head of the grouting gun enters the water inside the water storage tank. By soaking the discharge head of the grouting gun when not in use, the problem of grout solidification and blockage at the discharge head can be effectively reduced, thereby ensuring the smooth flow of grout when grouting is carried out again.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a grouting device for road construction using cement-stabilized crushed stone base courses.

[0034] Reference Figure 1 and Figure 2 A grouting device for cement-stabilized crushed stone base road construction includes a base plate 1, with casters 11 installed at the four corners of the lower end of the base plate 1, a support plate 12 fixed to the upper end of the base plate 1, a handrail 13 fixed to the upper end of the support plate 12, a controller 14 fixed to the side of the support plate 12, a storage tank 2 fixed to the upper end of the base plate 1, a cover plate 21 installed on the upper end of the storage tank 2, a pump 22 fixed to the side of the storage tank 2, the inlet end of the pump 22 connected to the storage tank 2, a guide pipe 23 fixed to the outlet end of the pump 22, a grouting gun 24 fixed to the end of the guide pipe 23 away from the pump 22, a feed pipe 15 fixed to the storage tank 2, a material leveling structure 3 between the cover plate 21 and the storage tank 2, and an anti-drying structure 4 on the upper end of the base plate 1.

[0035] When using this grouting device for grouting, the grout is poured into the storage tank 2 through the feed pipe 15. Then, the uniform mixing structure 3 is turned on to ensure that the grout is fully mixed and improve its uniformity. Holding the handle 13, the grouting device is pushed to the position where grouting is needed. Then, the operator holds the grouting gun 24 and points it toward the position where grouting is needed. Then, the extraction pump 22 is turned on to extract the grout from the storage tank 2 and send it to the grouting gun 24 through the guide pipe 23. Finally, the grout flows out through the grouting gun 24 to complete the grouting. After the grouting is completed, the grouting gun 24 is placed inside the anti-drying structure 4 to reduce the grout coagulation at the outlet of the grouting gun 24. Then, the device is pushed to the next position where grouting is needed for grouting.

[0036] Reference Figures 1-3The uniform material structure 3 includes a drive motor 31 fixed on the upper end of the cover plate 21. The output end of the drive motor 31 extends through the cover plate 21 and is rotatably connected to the cover plate 21. A first stirring shaft 32 is fixed on the output end of the drive motor 31. Several first stirring blades 33 are fixed on the first stirring shaft 32. Several second stirring shafts 34 are provided at the lower end of the cover plate 21. Several second stirring blades 35 are fixed on the second stirring shafts 34.

[0037] The first stirring blade 33 and the second stirring blade 35 are staggered.

[0038] In addition, a drive gear 36 is fixed on the first stirring shaft 32, a gear ring 361 is rotatably connected inside the cover plate 21, and a driven gear 362 is fixed on the upper end of the second stirring shaft 34. The driven gear 362 meshes with the drive gear 36 and the gear ring 361.

[0039] Furthermore, a connecting frame 363 is fixed on the first stirring shaft 32, and the connecting frame 363 is rotatably connected to the driven gear 362.

[0040] After adding slurry into the storage tank 2, the drive motor 31 is turned on, causing the drive motor 31 to drive the first stirring shaft 32 to rotate. The rotation of the first stirring shaft 32 drives the first stirring blade 33 to rotate, and at the same time drives the drive gear 36 to rotate. The rotation of the drive gear 36 drives the driven gear 362 to rotate. The driven gear 362 is restricted by the gear ring 361, so that the driven gear 362 rotates around the drive gear 36, thereby driving the second stirring shaft 34 and the second stirring blade 35 to rotate and revolve around the first stirring shaft 32. The first stirring shaft 32 drives the first stirring blade 33 to perform basic mixing. At the same time, the second stirring shaft 34 and the second stirring blade 35, which can rotate and revolve around the first stirring shaft 32, form a three-dimensional mixing field, which can perform multi-dimensional shearing, rolling and kneading of the slurry, so that the cement, aggregate, additives and other components can be fully mixed, effectively suppressing the sedimentation and stratification phenomenon, ensuring that the grouting slurry always maintains uniform and stable physical properties, and significantly improving the quality and durability of road base repair.

[0041] Reference Figure 3 A crossbar 37 is fixed at the lower end of the first stirring shaft 32. A vertical rod 371 is fixed at the end of the crossbar 37 away from the first stirring shaft 32. A scraper strip 372 is fixed on the side of the vertical rod 371. The scraper strip 372 is an elastic rubber strip and is in contact with the inner wall of the storage tank 2.

[0042] When the first stirring shaft 32 rotates, it drives the crossbar 37 to move. The rotation of the crossbar 37 drives the upright 371 to rotate, thereby causing the scraper 372 to rotate. The rotation of the scraper 372 can scrape off the material attached to the inner wall of the storage tank 2, further improving the uniformity of the material.

[0043] Reference Figure 2and Figure 3 The anti-drying structure 4 includes a water storage tank 41 fixed to the upper end of the base plate 1, a drain pipe 42 fixed to the water storage tank 41, a sealing cap installed on the drain pipe 42, water is added into the water storage tank 41 when in use, and an installation plate 43 fixed to the upper end of the water storage tank 41, with an installation hole 44 opened on the installation plate 43.

[0044] The mounting hole 44 has a fixing ring 45 inside, which is an elastic rubber ring.

[0045] During or after grouting operations, the grouting gun 24 is inserted into the fixing ring 45, allowing the discharge head of the grouting gun 24 to enter the water inside the water storage tank 41. The fixing ring 45 restricts the grouting gun 24. By soaking the discharge head of the grouting gun 24 when not in use, the problem of grout solidification and blockage at the discharge head can be effectively reduced, thus ensuring smooth flow of grout when grouting is performed again.

[0046] Working principle: When using this grouting device for grouting, the grout is poured into the storage tank 2 through the feed pipe 15. The drive motor 31 is turned on, causing the drive motor 31 to drive the first stirring shaft 32 to rotate. The rotation of the first stirring shaft 32 drives the first stirring blade 33 to rotate, and at the same time drives the drive gear 36 to rotate. The rotation of the drive gear 36 drives the driven gear 362 to rotate. The driven gear 362 is restricted by the gear ring 361, so that the driven gear 362 rotates around the drive gear 36, thereby driving the second stirring shaft 34 and the second stirring blade 35 to rotate and rotate around the first stirring shaft 32, thus achieving uniform material distribution. Subsequent operations... Personnel hold the grouting gun 24 and point it toward the location where grouting is needed. Then, the extraction pump 22 is turned on to extract the grout from the storage tank 2. The grout is then sent to the grouting gun 24 through the guide pipe 23 and finally flows out through the grouting gun 24 to complete the grouting. During the intervals or after the grouting operation, the grouting gun 24 is inserted into the fixing rubber ring 45 so that the discharge head of the grouting gun 24 enters the water inside the water storage tank 41. The fixing rubber ring 45 restricts the grouting gun 24. By soaking the discharge head of the grouting gun 24 when not in use, the problem of grout solidification and blockage at the discharge head can be effectively reduced.
