Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a grouting device for water conservancy projects. Background Technology

[0002] Water conservancy engineering refers to the engineering field that utilizes water resources, conducts hydrological surveys, and designs and constructs various water conservancy facilities. It encompasses water resource development and utilization, water environment management, and flood prevention. The main purpose of water conservancy engineering is to effectively manage water resources, meet human needs for water, and solve problems such as water shortages, flood control, and water pollution. Common water conservancy projects include reservoirs, hydropower stations, irrigation canals, and drainage systems.

[0003] Grouting in water conservancy engineering refers to the process of injecting grouting materials into soil or rock during the construction of water conservancy projects. The purpose of grouting is to reinforce the stability of soil or rock, improving its bearing capacity and impermeability. Common grouting materials include cement grout, bentonite grout, and polymer grout. In water conservancy projects, grouting is frequently used to repair and reinforce structures such as dams, dikes, canals, and tunnels to improve their safety and stability. Grouting work requires detailed design and construction processes to ensure that the grouting material can fully penetrate the soil or rock and form a solid grout body.

[0004] Traditional grouting equipment cannot effectively mix the raw materials evenly, and direct grouting may cause the nozzle to become clogged; air may enter during grouting, and if it is not compacted before grouting, it will reduce the service life of the concrete and has poor practicality.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention uses a drive motor and a mixing and conveying mechanism.

The mixed concrete is then moved into the grouting cylinder through the conveying pipe, thereby effectively improving the grouting rate of the device and increasing the work efficiency of the workers.

[0018] The servo motor drives the drive gear to rotate, which in turn drives the cam to rotate, which in turn drives the T-shaped rod to move up and down. Then, the vibrating rod slides along the outer wall of the support component's fixed seat, thereby compacting the concrete inside the grouting cylinder. This effectively prevents air bubbles from forming inside the grouting cylinder during grouting, thereby enhancing the hardness of the concrete setting and improving its service life.

[0019] The servo motor drives the drive gear to rotate, which in turn drives the driven gear to rotate. The driven gear then drives the shaped cam to rotate, and under the action of the compression spring, the entire moving mechanism moves back and forth. This allows the concrete inside the grouting cylinder to be vented, further preventing air bubbles from forming inside the grouting cylinder during grouting and thus improving the service life of the concrete.

The housing 826 is rotatably connected to the protrusion 83. The housing 826 is slidably connected to the lower part of the T-shaped rod 85.

[0035] like Figure 1 As shown, the surface of the base 1 is provided with a plurality of support rollers 11, the upper end face of the base 1 is fixedly connected to the lower end face of the support rollers 11, and the upper end face of the support rollers 11 is fixedly connected to the lower end face of the storage bin 10.

[0036] like Figure 3 As shown, the right end of the fixing block 824 is fixedly connected to the inner rear end face of the housing 7, the lower end face of the U-shaped plate 88 is slidably connected to the inside of the housing 7, and the right end face of the servo motor 81 is slidably connected to the inner right end face of the housing 7.

[0037] like Figure 2 As shown, the bottom end of the driving bevel gear 35 is meshed with the left end of the driven bevel gear 4, the upper end face of the driven bevel gear 4 is rotatably connected to the lower end face of the grouting cylinder 5, and the upper end face of the driven bevel gear 4 is fixedly connected to the upper end face of the fixed seat 9.

[0038] Working principle: After the invention is installed, the raw materials are placed in the storage bin 10 according to the proportion. When the raw materials enter the sleeve 36 from the bottom of the storage bin 10, the drive motor 31 is started. The output end of the drive motor 31 drives the conveying blade 37 fixedly connected to it to rotate. The raw materials and water are initially mixed inside the sleeve 36 by connecting to the water source outside the sleeve 36. Then the concrete is transported to the grouting cylinder 5 through the conveying pipe 38.

[0039] At the same time, as the drive shaft 32 rotates, it drives the belt 33 connected to it to rotate, which in turn drives the driven shaft 34 to rotate in the same direction as the drive shaft 32. Subsequently, it drives the drive bevel gear 35 fixed to the right end of the driven shaft 34 to rotate. The drive bevel gear 35 then drives the driven bevel gear 4 meshing with it to rotate. The driven bevel gear 4 drives the fixed seat 9 fixedly connected to its upper end face to rotate. The fixed seat 9 drives the box 7 fixedly connected to its upper end face to rotate, and causes the symmetrical connecting rod 89 slidably connected to the groove opened at the bottom of the box 7 to rotate. This drives the fixed roller 810 to rotate, and the fixed roller 810 drives the vibrating rod 811 fixedly connected to its surface to rotate. Since the two ends of the support rod 6 are fixedly connected to the base 1 and the grouting cylinder 5 respectively, the vibrating rod 811 will not throw out concrete when it rotates, thus avoiding an unsightly phenomenon.

[0040] While the housing 7 is rotating, the servo motor 81 is started. The output end of the servo motor 81 drives the protrusion 83 fixedly connected to it to rotate. The protrusion 83 drives the connecting block 84 fixedly connected to the rear end face of the protrusion 83 to rotate. Since the connecting block 84 slides inside the T-shaped rod 85, and under the action of the rotation of the protrusion 83, the T-shaped rod 85 moves up and down on the rear end face of the protrusion 83.

[0041] As the connecting block 84, carrying the T-shaped rod 85, moves from the lowest end of the protrusion 83 to the highest end, the support plate 87 fixed below the T-shaped rod 85 moves upward with the T-shaped rod 85. This causes the compression spring 86 fixedly connected to the upper end of the support plate 87 to be compressed. Subsequently, the T-shaped rod 85 pulls up the symmetrical connecting rod 89 fixedly connected to the bottom end of the T-shaped rod 85, and then pulls up the fixed roller 810 fixedly connected to the symmetrical connecting rod 89. This then pulls up the vibrating rod 811 fixedly connected to the fixed roller 810, thereby re-mixing the concrete that has been initially mixed between the grouting cylinder 5 and the fixed seat 9, allowing the raw materials to come into more complete contact.

[0042] Subsequently, as the connecting block 84 carries the T-shaped rod 85 from the top of the protrusion 83 to the bottom, the support plate 87 fixed below the T-shaped rod 85 moves downward with the T-shaped rod 85 and recovers under the characteristics of the compression spring 86. Then, the T-shaped rod 85 moves the symmetrical connecting rod 89 fixedly connected to the bottom of the T-shaped rod 85 downward, and then drives the fixed roller 810 fixedly connected to the symmetrical connecting rod 89 to move downward. This causes the vibrating rod 811 fixedly connected to the fixed roller 810 to move downward, thereby compacting the concrete that has been initially mixed between the grouting cylinder 5 and the fixed seat 9 again, reducing the air between the concrete and improving the service life of the concrete.

[0043] Simultaneously, the driving gear 821 fixed to the surface of the protrusion 83 will also rotate with the rotation of the protrusion 83, thereby driving the driven gear 822, which is meshed with the left end face of the driving gear 821, to rotate in the opposite direction. Under the action of the connecting rod 827, the driven gear 822 drives the irregular cam 823 to rotate. When the protruding part of the irregular cam 823 contacts the fixed block 824, it will cause the housing 826 to move forward inside the through groove 828 and put the return spring 825 into a compressed state, thereby driving the movement When mechanism 82 moves forward a certain distance, the vibrating rod 811 will strike the inner wall of grouting cylinder 5, causing the concrete attached to the inner wall of grouting cylinder 5 to be knocked off. When the non-protruding part of the shaped cam 823 contacts the fixing block 824, and under the action of the return spring 825, the housing 826 moves backward inside the through groove 828, which in turn drives the moving mechanism 82 to move backward a certain distance. At this time, the vibrating rod 811 will strike the outer wall of the fixing seat 9, causing the concrete attached to the outer wall of the fixing seat 9 to be knocked off.

[0044] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the scope and spirit of the invention, the scope of which is defined by the claims and their equivalents.
