Description

Technical Field

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

[0002] In the process of building construction and maintenance, grouting treatment of structural gaps is a key step in ensuring structural stability and durability.

[0003] Reference patent (publication number: CN221524340U; publication date: 2024-08-13) discloses a grouting device for building structure gaps, which includes: a motor fixedly connected to the upper surface of a base plate, a spiral conveying assembly fixedly connected to the output end of the motor, a grouting pipe fixedly connected to the outer surface of the motor, a material box fixedly connected to the upper surface of the grouting pipe, a mixing box fixedly connected to the output end of a hydraulic telescopic rod, a motor fixedly connected to the outer surface of the mixing box, a mixing blade connected to the output end of the motor via a rotating shaft, and a telescopic pipe provided on the outer surface of the mixing box. A sealing valve is provided inside the telescopic pipe to separate the mixing device from the material box and then connect them through the telescopic pipe, reducing the direct contact between the mixing device and the grouting device. This can protect the grouting device from potential damage or contamination from the mixing device, and can realize the automatic delivery of mixed grouting material to the grouting device. At the same time, the mixing and gap grouting devices do not interfere with each other and can work simultaneously, increasing the continuous construction time.

[0004] Based on the aforementioned patent, when the mud in the material box is insufficient, it is necessary to stop motor 1 and open the top cover 1 to replenish the material. This will cause the grouting work to be interrupted, making it impossible to achieve continuous and uninterrupted grouting operations, affecting the project progress and quality. Furthermore, when the mixing tank is loaded with material, it is prone to tipping over due to the shift in the center of gravity during the lifting process. Also, the direct use of the grouting pipe makes the operation inconvenient. When performing grouting operations, operators may not be able to freely and accurately control the grouting position and angle due to the limitations of the grouting pipe. At the same time, when mixing the material, it is easy to create dead zones in the mixing, resulting in low mixing efficiency. Therefore, this utility model provides a grouting device for building structure gaps. Utility Model Content

[0014] Beneficial effects

[0015] This utility model provides a grouting device for gaps in building structures. Compared with the prior art, it has the following advantages:

[0016] Firstly, this invention utilizes the rotation of the stirring rod to ensure thorough mixing of materials within the mixing tank, improving material uniformity and guaranteeing subsequent grouting effects. The scraper bracket effectively scrapes material from the inner wall of the mixing tank, reducing waste and simplifying cleaning. The included electric push rod allows for slight adjustment of the mounting cover, controlling the stirring rod's position within the mixing tank. This covers areas at different heights and alters the contact range and stirring trajectory between the stirring rod and the material, ensuring optimal mixing. It also brings the rod closer to hard-to-reach areas, ensuring uniform mixing throughout the tank and improving overall mixing quality. The quantity control component controls the sliding of the sealing plate by rotating the first bolt, precisely controlling the discharge amount to meet the material usage requirements of different construction scenarios and reduce waste.

[0017] Secondly, this utility model provides power through the pump body, enabling materials to be smoothly transported from the material box to the grouting pipe, ensuring the continuity and stability of the grouting process. The grouting pipe can then be used freely with the flexible hose, making operation simple and convenient. Simultaneously, the design of the slotted plate, baffle, and limiting plate allows the grouting pipe to be easily fixed to the mounting bracket when not in use, avoiding damage and clutter caused by haphazard placement, thus improving the overall neatness and ease of use of the equipment. Finally, the flange body facilitates the installation and disassembly of the connecting pipe and hose, simplifying equipment maintenance and the replacement of different pipes, improving the equipment's versatility and maintainability. Furthermore, the mixing tank and material box are vertically mounted on the base, aligned with the support direction of the base, reducing torque generated by lateral loads and preventing the equipment from tipping over during operation.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a grouting device for building structure gaps, including a mounting base 1, on which a mounting mechanism for the grouting equipment is provided, the mounting mechanism including:

[0026] The mixing assembly includes a second support frame 4 fixed at the edge of the mounting base 1, a mixing tank 401 fixed inside the second support frame 4, a mounting cover 403 connected by a lifting assembly on the upper end surface of the second support frame 4, a mixing assembly for mixing materials inside the mounting cover 403, a material control assembly for discharging materials at the lower end of the mixing tank 401, a first support frame 2 on the upper end surface of the mounting base 1, a material box 201 on the upper end of the first support frame 2, and the material box 201 located directly below the mixing tank 401.

[0027] The grouting assembly includes a material box 201 with a conduit 203 connected to it via a flow component at its lower end. One end of the conduit 203 is provided with a flange body 205, and one end of the flange body 205 is provided with a connecting pipe 206. The output end of the connecting pipe 206 is provided with a flexible hose 207, and the end of the flexible hose 207 is fixed with a grouting pipe 208. A fixing plate 6 is provided on one side of the mounting base 1. The fixing plate 6 is internally threaded with a second bolt 601, and the lower end of the second bolt 601 is rotatably connected with a rubber block 602.

[0028] In a preferred embodiment, the lower end of the mounting base 1 is provided with casters 7, and one end of the mounting base 1 is provided with a push rod bracket 701 for pushing. When it moves to the designated place, the second bolt 601 is rotated to make the rubber block 602 contact the ground.

[0029] Specifically, when the equipment needs to be moved to a designated location, the operator holds the push rod bracket 701 and applies pushing force through the push rod bracket 701. Since the lower end of the mounting base 1 is equipped with casters 7, the equipment can be easily moved to the designated location by the rolling action of the casters 7. After the equipment is moved to the designated location, the second bolt 601 is rotated. Since the second bolt 601 is threadedly connected to the fixing plate 6 and its lower end is rotatably connected to the rubber block 602, rotating the second bolt 601 will cause the rubber block 602 to move downwards until the rubber block 602 contacts the ground and generates sufficient pressure to fix the equipment on the ground, preventing the equipment from moving during operation, ensuring the stability and safety of the equipment during operation, and avoiding grouting quality problems caused by equipment movement.

[0030] In a preferred embodiment, the lifting assembly includes electric push rods 402 fixed on both sides of the upper surface of the second support frame 4, a mounting cover 403 fixedly connected to the top of the electric push rods 402, and the mounting cover 403 is in close contact with the upper surface of the mixing tank 401. The mixing assembly includes a drive shaft 404 rotatably connected inside the mounting cover 403, stirring rods 405 uniformly fixed on the outer wall of the drive shaft 404, a scraper bracket 406 fixed on the outer wall of the drive shaft 404 near the mounting cover 403, and one end of the scraper bracket 406 in close contact with the inner wall of the mixing tank 401. The metering assembly includes a discharge shell 5 fixed to the lower end of the mixing tank 401, and a metering shell 501 fixedly inserted through the interior of the discharge shell 5. A sealing plate 502 is slidably connected to the inner wall of the measuring housing 501. A first bolt 503 is threadedly connected to one side of the measuring housing 501. One end of the first bolt 503 is rotatably connected to the sealing plate 502. When it is necessary to open the mixing tank 401 for material addition, cleaning or maintenance, the electric push rod 402 is activated. The electric push rod 402 extends upward, driving the mounting cover 403 fixed at its top to move upward, so that the mounting cover 403 is separated from the mixing tank 401, thereby exposing the interior of the mixing tank 401. After the corresponding operation is completed, the electric push rod 402 is activated again to retract downward, driving the mounting cover 403 to move downward until the mounting cover 403 is in contact with the upper surface of the mixing tank 401.

[0031] Furthermore, the drive shaft 404 inside the mounting cover 403 starts to rotate under the drive of the motor, and the stirring rod 405, which is uniformly fixed on the outer wall of the drive shaft 404, rotates accordingly to stir and mix the material in the mixing box 401. One end of the scraper bracket 406 is in contact with the inner wall of the mixing box 401, which can scrape off the material attached to the inner wall of the mixing box 401 and prevent material residue from accumulating. The motor is installed at the upper end of the mounting cover 403.

[0032] The electric push rod 402 can be slightly raised and lowered to adjust the mounting cover 403, thereby controlling the position of the stirring rod 405 inside the mixing box 401. It can cover areas at different heights inside the mixing box 401, and can change the contact range and stirring trajectory between the stirring rod 405 and the material to ensure the stirring effect. At the same time, it can bring it closer to these dead corner areas to stir the material in the dead corners, ensuring that the material in the entire mixing box 401 is uniformly stirred and improving the overall stirring quality.

[0033] When it is necessary to control the discharge rate of material in the mixing tank 401, the first bolt 503 is rotated. Since the first bolt 503 is threadedly connected to the control housing 501 and one end is rotatably connected to the sealing plate 502, rotating the first bolt 503 will cause the sealing plate 502 to slide on the inner wall of the control housing 501. When the sealing plate 502 slides to one side, the opening of the discharge port will be reduced, thereby reducing the amount of material flowing out. When the sealing plate 502 slides in the opposite direction, the opening of the discharge port will be increased, thereby increasing the amount of material flowing out.

[0034] By adjusting the position of the sealing plate 502, the discharge speed and discharge volume of the material can be precisely controlled.

[0035] In a preferred embodiment, the flow assembly includes a discharge pipe 202 disposed at the lower end of the material box 201, a pump body 204 disposed at the output end of the discharge pipe 202, a conduit 203 located at the output end of the pump body 204, a limiting plate 209 fixed to the outer wall of the grouting pipe 208, a mounting bracket 3 fixed to the upper end of the mounting base 1, a slot plate 301 fixed to the top of the mounting bracket 3, the lower end face of the limiting plate 209 being in contact with the surface of the slot plate 301, a baffle 302 rotatably connected to the slot plate 301 through an opening in the slot plate 301, and a locking bolt connected to the slot plate 301 at one end of the baffle 302.

[0036] After the mixed material enters the material box 201 through the flow control component, the pump body 204 in the flow component is started. The pump body 204 draws the material in the material box 201 out through the discharge pipe 202 and delivers it to the conduit 203. The material flows through the conduit 203, flange body 205, connecting pipe 206 and hose 207, and finally reaches the crack filling pipe 208. When the crack filling pipe 208 is not needed, the outer wall limiting plate 209 of the crack filling pipe 208 is placed on the slot plate 301, so that the lower end face of the limiting plate 209 is in contact with the surface of the slot plate 301. Then, the baffle 302 is rotated to block the crack filling pipe 208, and the baffle 302 is connected and fixed to the slot plate 301 by the locking bolt, thereby fixing the crack filling pipe 208 on the mounting bracket 3.

[0037] The pump body 204 provides power so that the material can be smoothly transported from the material box 201 to the grouting pipe 208, ensuring the continuity and stability of the grouting process.

[0038] Furthermore, the design of the slot plate 301, baffle 302 and limiting plate 209 allows the filling tube 208 to be easily fixed on the mounting bracket 3 when not in use, avoiding damage and mess caused by random placement of the filling tube 208, and improving the overall neatness and ease of use of the equipment.

[0039] The flange body 205 facilitates the installation and disassembly of the connecting pipe 206 and the hose 207, making equipment maintenance and replacement of different pipes easier, and improving the equipment's versatility and maintainability.

[0040] The motor mentioned above is a servo motor with model number EDSMT-2T110-020A, and the pump body model is SFY-10. These are existing technologies and will not be elaborated on further.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] During operation, the operator holds the push rod bracket 701 and applies pushing force to move the equipment to the designated position using the casters 7 at the lower end of the mounting base 1. Then, the operator rotates the second bolt 601 on the fixing plate 6, causing the rubber block 602, which is rotatably connected to it, to move downwards and make tight contact with the ground, thus fixing the equipment to ensure operational stability. When materials need to be added, the electric push rods 402 on both sides of the upper end face of the second support frame 4 are activated, extending upwards to raise the mounting cover 403. After the materials are added to the mixing tank 401, the electric push rods 402 are retracted, allowing the mounting cover 403 to fit against the upper end face of the mixing tank 401. Then, the motor installed on the upper end of the mounting cover 403 is activated, driving the drive shaft 404 to rotate. This causes the stirring rods 405 on the outer wall to mix the materials, while the scraper bracket 406 on the drive shaft 404 rotates against the inner wall of the mixing tank 401, scraping off any adhering materials. The position of the mounting cover 403 can be slightly adjusted by the electric push rod 402 to change the height of the stirring rod 405 in the mixing box 401, ensuring that the material is mixed evenly. After mixing, the first bolt 503 on the control housing 501 is rotated to push the sealing plate 502 to slide inside the control housing 501, adjusting the opening of the discharge port to control the amount of material falling into the material box 201 located directly below through the discharge housing 5. Then, the pump body 204 in the flow assembly is started to draw the material in the material box 201 out through the discharge pipe 202, and transport it to the grouting pipe 208 for grouting operation through the conduit 203, flange body 205, connecting pipe 206 and hose 207. When the grouting pipe 208 is not in use, the limiting plate 209 on its outer wall is placed on the slot plate 301 at the top of the mounting bracket 3, the baffle 302 is rotated to block the limiting plate 209, and it is fixed with the locking bolt to complete the storage of the grouting pipe 208.
