Description

Technical Field

[0001] This utility model relates to the field of engineering construction, and more specifically, to a beam and slab cyclic grouting construction device. Background Technology

[0002] In the construction of bridges and roads, many devices are used. For road surface and bridge deck construction, compaction grouting is a primary method for reinforcing the foundation. Compaction grouting involves injecting a very thick grout into holes drilled beforehand in the foundation soil and squeezing it into the soil. Grout bubbles form at the injection site, and the diffusion of the grout compresses the surrounding soil. The grout completely replaces the soil within the grouting area. A large plastic deformation zone exists in the vicinity of the grouting area, while the soil further away from the grout bubbles undergoes elastic deformation, resulting in a significant increase in soil density.

[0003] In the prior art, Chinese utility model patent with publication number CN222513194U discloses a construction compaction grouting device. Although the above-mentioned prior art effectively improves the fluidity of the slurry and avoids the problem of solidification by cooperating with the mixing blades and spiral mixing plates, in actual use, the mixing blades and spiral mixing plates in the mixing components of the prior art require independent drive sources to drive them. Although this multi-drive design achieves mixing in function, it also increases the manufacturing cost of the equipment and the complexity of electrical control. Furthermore, the operation of multiple motors means higher maintenance costs. In view of this, we propose a beam and slab circulating grouting construction device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenience in using some current beam and slab circulatory grouting construction devices.

[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a beam and slab circulating grouting construction device, including a base. A mud tank is fixedly connected to the upper surface of the base. A first rotating rod is rotatably connected inside the mud tank. A stirring rod is fixedly connected to the surface of the first rotating rod. Two sealing boxes are fixedly connected to the inner wall of the mud tank. A second rotating rod is rotatably connected to the surface of the sealing box. A stirring blade is fixedly connected to the outside of the second rotating rod. A first cavity is opened inside the sealing box. A transmission assembly is arranged inside the first cavity. A second cavity is opened inside the top plate of the mud tank. A connecting assembly is arranged inside the second cavity.

[0006] As a preferred technical solution of this application, the transmission assembly includes a transmission rod, which is rotatably connected to the inside of the first cavity. A bevel gear is fixedly sleeved on the outside of the transmission rod. The second rotating rod rotatably penetrates into the inside of the first cavity. A bevel gear is also fixedly sleeved on one end of the second rotating rod located inside the first cavity. Two adjacent bevel gears are meshed and connected.

[0007] As a preferred technical solution of this application, a spiral blade is fixedly sleeved on the outside of the first rotating rod, and the spiral blade is located between the axially arranged stirring rods.

[0008] As a preferred technical solution of this application, the upper end of the first rotating rod rotates through the interior of the second cavity, and a motor is fixedly connected to the upper surface of the mud box. The output shaft of the motor rotates through the interior of the second cavity and is fixedly connected to the first rotating rod through a coupling.

[0009] As a preferred technical solution of this application, the connecting assembly includes two support shafts, both of which are rotatably connected inside the second cavity. The lower ends of the two support shafts rotatably penetrate into the interiors of the two sealed boxes, and the two support shafts are fixedly connected to two transmission rods respectively.

[0010] As a preferred technical solution of this application, two first synchronous pulleys are fixedly sleeved on one end surface of the first rotating rod located inside the second cavity, and second synchronous pulleys are fixedly sleeved on the surfaces of the two support shafts. The first and second synchronous pulleys located at the same height are externally meshed with a synchronous belt.

[0011] As a preferred technical solution of this application, a pump body is provided on the upper surface of the base, the input end of the pump body is connected to the mud tank, the output end of the pump body is provided with a discharge pipe, a support component is provided on the surface of the base, and a control panel is provided on the surface of the mud tank.

[0012] As a preferred technical solution of this application, an installation chamber is provided inside the side wall of the mud tank, and a heating pipe is installed inside the installation chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. Through the coordination between the first rotating rod, stirring rod, spiral blade, second rotating rod, and agitating blade, the mixing effect of the mud inside the mud tank is effectively guaranteed. Furthermore, through the motor, synchronous belt, and synchronous pulley, only one motor is needed to drive the stirring rod, spiral blade, and agitating blades on both sides to rotate simultaneously. This eliminates the need for multiple independent drive sources, greatly simplifies the electrical control system, and reduces the manufacturing cost, energy consumption, and subsequent maintenance costs of the equipment.

[0016] 2. By simultaneously equipping the first rotating rod with a stirring rod and segmented spiral blades, the stirring rod disperses the mud, while the spiral blades continuously lift the slurry from the bottom of the mud tank, effectively preventing sedimentation and solidification. Furthermore, the stirring blades on both sides simultaneously agitate the slurry in the edge area of ​​the tank, eliminating dead zones in the stirring process, ensuring the uniformity and stability of the slurry, avoiding blockage problems caused by slurry segregation or solidification, and improving the quality of the mud.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A beam and slab circulating grouting construction device includes a base 1, a mud tank 2 fixedly connected to the upper surface of the base 1, and a feed inlet matched with the mud tank 2. A first rotating rod 3 is rotatably connected inside the mud tank 2, and a stirring rod 4 is fixedly connected to the surface of the first rotating rod 3. Two sealing boxes 5 are fixedly connected to the inner wall of the mud tank 2. A second rotating rod 6 is rotatably connected to the surface of the sealing box 5. An agitator blade 7 is fixedly connected to the outside of the second rotating rod 6. A first cavity 8 is opened inside the sealing box 5, and a transmission component is arranged inside the first cavity 8. A second cavity 9 is opened inside the top plate of the mud tank 2, and a connecting component is arranged inside the second cavity 9.

[0031] In the above embodiments, when cement, water and admixtures are added to the inside of the mud tank 2, high-precision weighing sensors and intelligent metering algorithms can be used to accurately control the ratio of cement, water and admixtures, ensuring the quality of the slurry from the source.

[0032] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the transmission assembly includes a transmission rod 10, which is rotatably connected inside the first cavity 8. Several bevel gears 11 are fixedly sleeved on the outside of the transmission rod 10. The second rotating rod 6 rotatably penetrates into the inside of the first cavity 8. A bevel gear 11 is fixedly sleeved at one end of the second rotating rod 6 inside the first cavity 8. Two adjacent bevel gears 11 mesh with each other. The rotation of the transmission rod 10 and the transmission of the two bevel gears 11 can drive the rotation of the second rotating rod 6. The rotation of the second rotating rod 6 can drive the rotation of the stirring blade 7, thereby realizing the agitation of the slurry inside the mud tank 2 and improving the uniformity of mixing.

[0033] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a spiral blade 13 is fixedly sleeved on the outside of the first rotating rod 3. The spiral blade 13 is located between the axially arranged stirring rods 4. The first rotating rod 3 drives the stirring rods 4 to rotate, which in turn drives the spiral blade 13 to rotate. Thus, the rotation of the spiral blade 13 can lift the mud on the lower side upwards by a certain distance, further ensuring the mixing effect of cement, water and admixtures inside the mud tank 2.

[0034] The upper end of the first rotating rod 3 rotates and penetrates into the interior of the second cavity 9. A motor 12 is fixedly connected to the upper surface of the mud tank 2. The output shaft of the motor 12 rotates and penetrates into the interior of the second cavity 9 and is fixedly connected to the first rotating rod 3 through a coupling. The first rotating rod 3 can be driven to rotate by starting the motor 12 through an external controller.

[0035] Among them, the motor 12 is also equipped with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail in this article.

[0036] Example 2

[0037] The beam-slab circulating grouting construction device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the connecting assembly includes two support shafts 14, both of which are rotatably connected inside the second cavity 9. The lower ends of the two support shafts 14 rotatably penetrate into the interiors of the two sealed boxes 5, and the two support shafts 14 are fixedly connected to the two transmission rods 10 respectively.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, two first synchronous pulleys 15 are fixedly sleeved on one end surface of the first rotating rod 3 located inside the second cavity 9, and two second synchronous pulleys 16 are fixedly sleeved on the surfaces of the two support shafts 14. The first synchronous pulleys 15 and the second synchronous pulleys 16 located at the same height are externally meshed with a synchronous belt 17. The rotation of the first rotating rod 3 and the transmission between the first synchronous pulleys 15, the second synchronous pulleys 16 and the synchronous belt 17 can drive the rotation of the two support shafts 14.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a pump body 20 is provided on the upper surface of the base 1. The input end of the pump body 20 is connected to the mud tank 2. The output end of the pump body 20 is provided with a discharge pipe 21. A support component 22 is provided on the surface of the base 1. A control panel 23 is provided on the surface of the mud tank 2.

[0040] In the above embodiments, high-density polyethylene (HDPE) or nylon (PA) pipes are preferred for conveying mud. Their inner walls are smooth and their coefficient of friction is low, much lower than that of traditional metal corrugated pipes or rubber pipes. This can significantly reduce the frictional resistance along the flow of slurry, and within the allowable range, pipes with larger diameters can be selected to ensure the stability of mud conveying.

[0041] The pump body 20 and the support assembly 22 are both existing structures. For details, please refer to the existing patent with announcement number CN222513194U. Since they are conventional technical means in this field, they will not be described in detail here.

[0042] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, an installation chamber 18 is provided inside the side wall of the mud tank 2. A heating pipe 19 is installed inside the installation chamber 18, which heats the mud inside the mud tank 2.

[0043] The usage process of the beam and slab circulating grouting construction device provided by this utility model is as follows:

[0044] Workers add the proportioned cement, water, and additives into the mud tank 2. Then, the motor 12 is started by the external controller, which drives the first rotating rod 3 to rotate. The rotation of the first rotating rod 3 drives the mixing rod 4 and the spiral blade 13 to rotate. The rotation of the spiral blade 13 lifts the mud on the lower side upwards a certain distance, further ensuring the mixing effect of cement, water, and additives inside the mud tank 2.

[0045] In addition, the rotation of the first rotating rod 3 and the transmission between the first synchronous pulley 15, the second synchronous pulley 16 and the synchronous belt 17 can drive the rotation of the two side support shafts 14. The rotation of the support shafts 14 can drive the rotation of the transmission rod 10. The rotation of the transmission rod 10 and the transmission of the two bevel gears 11 can drive the rotation of the second rotating rod 6. The rotation of the second rotating rod 6 can drive the rotation of the stirring blades 7, thereby realizing the agitation of the slurry inside the mud tank 2 and improving the uniformity of mixing.
