Description

Technical Field

[0001] This invention relates to the field of construction equipment technology for civil engineering projects, and in particular to a grouting device for structural gaps in civil engineering projects. Background Technology

[0002] In civil engineering, grouting repair of structural gaps (such as concrete cracks, masonry joints, and precast component splicing joints) is a key process to ensure the durability and safety of structures.

[0003] In practical applications, existing equipment often requires slurry preparation in ground mixers before manual transport to the grouting point. During transport, the slurry is prone to sedimentation and segregation, leading to uneven grouting strength. While some smaller equipment integrates mixing functions, it uses only a single-shaft mixing rod, limiting the mixing range and causing material to clump at the bottom of the tank, making it difficult to guarantee slurry uniformity. Existing grouting equipment often uses rigid connections or simple seals in its delivery pipelines, leading to leakage and blockages during high-pressure slurry transport. Furthermore, pipeline height adjustment relies heavily on manual lifting or scaffolding, which is inefficient and poses safety risks associated with working at heights. Traditional grouting equipment often uses wheeled bases, making it prone to slipping and getting stuck on gravel or muddy surfaces, hindering site relocation. Frequent movement of equipment or adjustment of supports is necessary for gaps of varying heights and angles, making precise alignment difficult, resulting in low construction efficiency and hindering practical application and operation.

[0036] The bottom of the base 1 is provided with a triangular track 29, and the top of the base 1 is fixedly connected with two push rods 33. The outer side of each push rod 33 is connected with a control handle sleeve 34. The outer side of the mixing tank 2 is fixedly connected with a filling pipe 35, which communicates with the inside of the mixing tank 2.

[0037] Working principle:

[0038] During use, construction personnel inject cement-based slurry, admixtures, water, and other materials through the injection pipe 35 on the outside of the mixing tank 2. The multi-port design of the injection pipe 35 allows for the simultaneous injection of different materials, improving material preparation efficiency. The turntable 3 at the top of the mixing tank 2 is driven to rotate by a built-in drive motor, and the rotating shaft 6 at the bottom of the turntable 3 rotates synchronously and is kept stable by the support of the bracket 5. The turntable 3 drives the first stirring rods 7, which are evenly distributed at the bottom, to revolve in a circular motion. At the same time, the gear 4 at the top of the first stirring rod 7 meshes with the tooth groove on the inner wall of the mixing tank 2. The gear 4 rotates on its own axis as it revolves, thereby driving the first stirring rod 7 to rotate at high speed. This combination of revolution and rotation allows the first stirring rod 7 to sweep across most of the tank while also providing strong shearing and mixing to specific areas of the material. The rotating shaft 6 drives the second stirring rod 8 at the bottom of the support 5 to rotate synchronously. The second stirring rod 8 penetrates deep into the bottom of the mixing tank 2 to agitate the deposited material, preventing clumping or sedimentation at the bottom of the tank. The three-dimensional stirring of the first stirring rod 7 and the deep agitation of the second stirring rod 8 complement each other, ensuring that the material in the tank is fully mixed at different heights and in different areas, ultimately resulting in a highly uniform and fluid grout.

[0039] After mixing, the delivery pump 10 on the base 1 is started. Under the pump pressure, the slurry is drawn from the bottom of the mixing tank 2 into the delivery pump 10 through the first delivery pipe 9, and then pumped into the second delivery pipe 11 by the delivery pump 10. The slurry flows upward along the second delivery pipe 11 into the first extension pipe 12, and then turns through the rotary joint 21 into the third delivery pipe 22. Finally, it is precisely injected into the gaps in the building structure through the port of the second extension pipe 23. Sealing sleeves 13 are installed at the joints between the second delivery pipe 11 and the first extension pipe 12, and between the third delivery pipe 22 and the second extension pipe 23. The sealing sleeves 13 are made of wear-resistant rubber and fit tightly against the inner wall of the pipe, completely sealing the annular gaps between the second delivery pipe 11 and the first extension pipe 12, and between the third delivery pipe 22 and the second extension pipe 23, to prevent high-pressure slurry from seeping into the gaps and causing leakage or pipe blockage. The sealing sleeves 13 also limit the radial sway of the pipe, so that the first extension pipe 12 and the second extension pipe 23 remain stable and coaxial during expansion and contraction, reducing pipe wear.

[0040] The rotary joint 21 allows the third delivery pipe 22 to rotate freely during the lifting process. Construction personnel can flexibly adjust the grouting direction of the second extension pipe 23 according to the angle of the grouting gap, adapting to the grouting needs of different positions without moving the entire equipment. The first servo motor 28 at the bottom of the base plate 31 is started, and the motor output shaft drives one of the rotating drums 32 to rotate. The synchronous chain 19 between the two rotating drums 32 ensures that they rotate synchronously, avoiding tilting of the equipment due to unilateral lifting. The linkage block 15 inside the rotating drum 32 slides and engages with the sliding groove 17 on the inner wall of the rotating drum 32 through the outer slider 18. The slider 18 restricts the linkage block 15 from rotating with the rotating drum 32 and can only make vertical lifting and lowering movements along the sliding groove 17.

[0041] The threaded rod 16 at the top of the linkage block 15 rises and falls synchronously with the linkage block 15, pushing the connecting plate 20 to move the rotary joint 21, the first extension pipe 12, and the third delivery pipe 22 up and down as a whole, realizing a wide range of height adjustment of the grouting port to adapt to different grouting positions from the ground to higher ground; rotating the screw 26 on the outside of the second fixing plate 25, the screw 26 pushes the first fixing plate 24 through threaded transmission, causing the second extension pipe 23 to slide inside the third delivery pipe 22, precisely adjusting the extension length of the grouting port to achieve millimeter-level alignment, ensuring that the grout is completely injected into the gap; the triangular track 29 at the bottom of the base 1 is made of high-grip rubber material, with a large ground contact area and low pressure, which can easily adapt to complex road surfaces such as gravel, mud, and potholes on the construction site, preventing the equipment from getting stuck or slipping. Construction personnel can flexibly control the triangular track 29 to move the equipment by pushing the rod 33 and rotating the anti-slip textured control sleeve 34, quickly transferring to the next grouting operation point, greatly improving construction efficiency.
