Description

Technical Field

[0001] This utility model relates to the field of grouting device technology, specifically a grouting device for building construction. Background Technology

[0002] Construction engineering refers to the planning, surveying, design, construction, and completion of buildings and ancillary structures and facilities for the construction, renovation, or expansion of buildings and ancillary structures and facilities. It also includes the completed engineering entities and the installation of supporting lines, pipelines, and equipment. It refers to the construction of various houses and buildings, also known as construction workload. This part of the investment must be realized through construction activities. In the process of construction, in order to enhance the overall structural stability of the building, grouting devices are usually used to grout the gaps in the building.

[0003] For example, Chinese patent CN220815037U discloses a grouting device for building construction. The grouting device includes: a base frame with multiple rollers symmetrically arranged on its bottom side; a material cylinder located above the base frame, equipped with a material pump, a guide hose at the output end of the material pump, and a grouting head at the end of the guide hose away from the material pump; a shock-absorbing mechanism located between the material cylinder and the base frame; and a wall-scraping mechanism for scraping away concrete slurry adhering to the inner wall of the material cylinder. The device involves placing concrete slurry inside the material cylinder and propelling the grouting device forward. During grouting, the operator holds the grouting head towards the location to be grouted, and uses the material pump to extract the concrete slurry from the material cylinder for grouting. The wall-scraping mechanism scrapes away the concrete slurry adhering to the inner wall of the material cylinder, preventing concrete slurry from adhering and being wasted.

[0004] Although the aforementioned patent uses a scraping mechanism to remove concrete slurry adhering to the inner wall of the material cylinder, thus avoiding waste, the material guiding hose is exposed on the outside when the grouting device is not used, making it prone to scratches and reducing its practicality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grouting device for building construction. It has advantages such as being able to retract the material guide hose when not using the grouting device, reducing the possibility of scratches on the outer side. This solves the problem that when the grout guide hose is not used, the entire material guide hose is exposed on the outside, which is prone to scratches and reduces its practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grouting device for building construction, comprising a tank, a handle frame provided on the left side of the tank, a winding mechanism provided on the right side of the tank, a feed pipe connected to the left side of the upper surface of the tank, a mixing mechanism provided on the upper surface of the tank, a concrete conveying pump provided on the right side of the tank, a connecting pipe connected to the bottom end of the tank, the end of the connecting pipe away from the tank being fixedly connected to the input end of the concrete conveying pump, and four universal wheels provided on the lower surface of the tank;

[0007] The winding mechanism includes support frames arranged on the front and rear sides of the right side of the tank. A rotating tube is rotatably connected between the front and rear support frames via bearings. A winding wheel is arranged on the outer side of the rotating tube. A first motor is arranged on the front side of the front support frame. The output shaft of the first motor rotatably passes through the front and rear support frames and is fixedly connected to the front side of the rotating tube.

[0008] The winding mechanism also includes an output pipe fixed to the output end of the concrete conveying pump. The end of the output pipe away from the concrete conveying pump is rotatably connected to a fixed pipe through a sealed bearing. The fixed pipe is located inside the back of the rotating pipe. The other end of the fixed pipe passes through the rotating pipe and the winding wheel and is connected to a guide hose body. The guide hose body is wound around the outside of the winding wheel. The end of the guide hose body away from the winding wheel is connected to a grouting head. An insertion platform is fixed to the right side of the upper surface of the tank by bolts. The grouting head is slidably inserted into the inside of the insertion platform.

[0009] Furthermore, the stirring mechanism includes a second motor mounted on the upper surface of the tank via a mounting bracket. A rotating rod is rotatably connected to the top wall of the inner cavity of the tank via a sealed bearing. At least two stirring paddles are provided on the outer side of the rotating rod. The top end of the rotating rod rotatably passes through the tank and is fixedly connected to the output shaft of the second motor. Connecting rods are provided on both the left and right sides of the at least two stirring paddles. A scraper is provided on the side of the connecting rod away from the stirring paddle, and the scraper is in contact with the inner wall of the tank.

[0010] Furthermore, a guide bucket is connected to the top of the feed pipe.

[0011] Furthermore, the lower surface of the scraper is in contact with the bottom wall of the tank.

[0012] Furthermore, a fixing ring is provided on the right side of the tank, and the connecting pipe passes through the fixing ring.

[0013] Furthermore, the back of the rotating tube rotates through the rear support frame and extends to the rear side of the rear support frame.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. When not in use, this construction grouting device can be operated by starting the first motor in reverse (or forward). The first motor drives the rotating tube to rotate counterclockwise (or clockwise), which in turn drives the take-up wheel to rotate counterclockwise (or clockwise). The counterclockwise (or clockwise) rotation of the take-up wheel can wind up the material guide hose, reducing the risk of scratches on the outside and knots in the material guide hose. When in use, the first motor can be started in forward (or reverse). The first motor drives the rotating tube to rotate clockwise (or counterclockwise), which in turn drives the take-up wheel to rotate clockwise (or counterclockwise). The clockwise (or counterclockwise) rotation of the take-up wheel can unwind the material guide hose. Once the material guide hose has been unwound to a certain length, the concrete pump can be started. The grout inside the tank is then transported to the grouting head through the connecting pipe, output pipe, fixed pipe, and material guide hose. Finally, the grouting operation can be performed on the gaps in the building by hand-held grouting head.

[0016] 2. This construction grouting device can inject a certain amount of concrete slurry into the tank through the feed pipe. Then, the second motor can be started to drive at least two agitators to mix the concrete slurry inside the tank evenly. At the same time, the scrapers on the left and right sides rotate to scrape off the concrete slurry adhering to the inner wall of the tank, thereby avoiding the waste of concrete slurry.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This utility model provides a grouting device for building construction, including a tank 1. A handle 2 is provided on the left side of the tank 1, and a winding mechanism 3 is provided on the right side of the tank 1. The winding mechanism 3 can wind up the material guide hose to reduce the possibility of scratches on the outside. A feed pipe 4 is connected to the left side of the upper surface of the tank 1. A stirring mechanism 5 is provided on the upper surface of the tank 1 to prevent concrete slurry from adhering and being wasted. A concrete delivery pump 6 is provided on the right side of the tank 1. A connecting pipe 7 is connected to the bottom end of the tank 1. The end of the connecting pipe 7 away from the tank 1 is fixedly connected to the input end of the concrete delivery pump 6. Four casters 8 are provided on the lower surface of the tank 1.

[0025] In this embodiment, the top end of the feed pipe 4 is connected to the guide bucket 9, the right side of the tank body 1 is provided with a fixing ring 10, and the connecting pipe 7 is located inside the fixing ring 10.

[0026] Please see Figures 2 to 4 In order to wind up the material guide hose and reduce the possibility of scratches on the outside, in this embodiment, the winding mechanism 3 includes support frames 301 arranged on the front and rear sides of the right side of the tank body 1. A rotating tube 302 is rotatably connected between the front and rear support frames 301 through bearings. A winding wheel 303 is arranged on the outside of the rotating tube 302. A first motor 304 is arranged on the front side of the front support frame 301. The output shaft of the first motor 304 rotates through the front and rear support frames 301 and is fixedly connected to the front side of the rotating tube 302.

[0027] In this embodiment, the winding mechanism 3 also includes an output pipe 305 fixed to the output end of the concrete conveying pump 6. The end of the output pipe 305 away from the concrete conveying pump 6 is rotatably connected to a fixed pipe 306 through a sealed bearing. The fixed pipe 306 is located inside the back of the rotating pipe 302. The other end of the fixed pipe 306 passes through the rotating pipe 302 and the winding wheel 303, and is connected to the guide hose body 307. When the grouting device is not used, the first motor 304 can be started to drive the rotating pipe 302 to rotate, which in turn drives the winding wheel 303 to rotate. By rotating the winding wheel 303, the guide hose body 307 can be wound up, reducing the possibility of knotting in the guide hose body 307.

[0028] In this embodiment, the material guide hose body 307 is wound around the outside of the take-up reel 303. The end of the material guide hose body 307 away from the take-up reel 303 is connected to the grouting head 308. The right side of the upper surface of the tank body 1 is fixed with a placement platform 309 by bolts. The grouting head 308 is slidably inserted into the interior of the placement platform 309. The back of the rotating pipe 302 rotates through the rear support frame 301 and extends to the rear side of the rear support frame 301. The connecting pipe 7 and the output pipe 305 are both metal pipes.

[0029] It should be noted that when using a grouting device at a construction site, the first motor 304 is started first. The first motor 304 drives the take-up wheel 303 to rotate, causing the material guide hose body 307 to unwind to a certain length. Then, the concrete delivery pump 6 is started, and the grout inside the tank 1 is transported to the grouting head 308 through the connecting pipe 7, output pipe 305, fixed pipe 306, and material guide hose body 307. Finally, the grouting operation can be performed on the gaps in the building by holding the grouting head 308.

[0030] Please see Figure 5 To avoid concrete slurry adhering and wasting, in this embodiment, the mixing mechanism 5 includes a second motor 501 mounted on the upper surface of the tank 1 via a mounting bracket. A rotating rod 502 is rotatably connected to the top wall of the inner cavity of the tank 1 via a sealed bearing. At least two mixing paddles 503 are provided on the outer side of the rotating rod 502. The top end of the rotating rod 502 rotatably passes through the tank 1 and is fixedly connected to the output shaft of the second motor 501. Connecting rods 504 are provided on both the left and right sides of the at least two mixing paddles 503. Scrapers 505 are provided on the side of the connecting rods 504 on both the left and right sides that are close to the inner wall of the tank 1. The opposite sides of the scrapers 505 on both the left and right sides are in contact with the left and right side walls of the inner cavity of the tank 1.

[0031] In this embodiment, at least two stirring paddles 503 are evenly distributed on the outside of the rotating rod 502, and the lower surfaces of the scrapers 505 on both the left and right sides are in contact with the bottom wall of the inner cavity of the tank 1.

[0032] It should be noted that during grouting, a certain amount of concrete slurry can be injected into the tank 1 through the feed pipe 4. Then, the second motor 501 can be started, which drives at least two mixing blades 503 to mix the concrete slurry inside the tank 1 evenly. At the same time, it drives the scrapers 505 on the left and right sides to rotate and scrape off the concrete slurry adhering to the inner wall of the tank 1, avoiding the waste of concrete slurry. With the cooperation of the four casters 8 and the handle frame 2, the grouting device can be moved on the ground.

[0033] The working principle of the above embodiments is as follows:

[0034] (1) When the grouting device is not required, the first motor 304 can be started to rotate in reverse (or forward). The first motor 304 drives the rotating tube 302 to rotate counterclockwise (or clockwise), which in turn drives the winding wheel 303 to rotate counterclockwise (or clockwise). Then, by rotating the winding wheel 303 counterclockwise (or clockwise), the material guide hose body 307 can be wound up, thereby reducing the occurrence of knots in the material guide hose body 307.

[0035] (2) When the grouting device is needed, the first motor 304 can be started to rotate forward (or reverse). The first motor 304 drives the rotating tube 302 to rotate clockwise (or counterclockwise), which in turn drives the winding wheel 303 to rotate clockwise (or counterclockwise). Then, the winding wheel 303 rotates counterclockwise (or clockwise) to unwind the material guide hose body 307. When the material guide hose body 307 has been unwound to a certain length, the concrete conveying pump 6 is started. The grout inside the tank 1 can be transported to the grouting head 308 through the connecting pipe 7, the output pipe 305, the fixed pipe 306 and the material guide hose body 307. Finally, the grouting operation is carried out on the gaps of the building by holding the grouting head 308.

[0036] (3) A certain amount of concrete slurry can be injected into the tank 1 through the feed pipe 4. Then, the second motor 501 can be started to work. The second motor 501 drives no less than two stirring paddles 503 to stir the concrete slurry inside the tank 1 evenly. At the same time, it drives the scrapers 505 on the left and right sides to rotate and scrape off the concrete slurry adhering to the inner wall of the tank 1 to avoid the concrete slurry from sticking and being wasted.

[0037] (4) The grouting device can be moved on the ground by the cooperation between the four casters 8 and the handle frame 2.
