Description

Technical Field

[0001] This application relates to the field of foundation grouting technology, and in particular to a high-efficiency grouting device for foundation treatment. Background Technology

[0002] The special flooring of hazardous chemical parking lots in chemical industrial parks is a "high-end product" in flooring. Its "wear-resistant, heavy-duty, non-sparking, and anti-static flooring" faces many special requirements and technical challenges during construction. Hazardous chemical vehicles carry heavy loads, and if the parking lot foundation is not sufficiently compacted or the soil is loose, the flooring is prone to cracking. Foundation grouting is a common method. This involves drilling holes at designated locations in the foundation, inserting grouting pipes into the holes, and injecting prepared grout through the pipes. The grout combines with the soil to increase the foundation strength. Foundation grouting devices facilitate grouting treatment for workers, improving work efficiency.

[0003] Existing foundation treatment grouting devices typically consist of a mixing tank, a grouting pump, and grouting pipes. The mixing tank is usually equipped with a mixing device consisting of multiple blades.

[0004] The existing technical solutions mentioned above have the following drawbacks: during grouting, the grout tends to adhere to the walls and bottom of the mixing tank, forming sediment and hardening, resulting in grout waste and making it difficult to clean the grouting device. Utility Model Content

[0005] This application provides a high-efficiency grouting device for foundation treatment, which aims to reduce grout adhesion to the inner wall of the mixing tank and facilitate cleaning of the grouting device.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A high-efficiency grouting device for foundation treatment includes a base plate, on which a grouting pump is mounted. A grouting pipe is connected to the discharge end of the grouting pump. A mixing tank is fixedly attached to the base plate. The bottom surface of the mixing tank is machined into a funnel shape. A discharge pipe is connected to the bottom of the mixing tank, one end of which is connected to the inlet end of the grouting pump. A motor is mounted on the top of the mixing tank. A rotating shaft is rotatably mounted inside the mixing tank. One end of the rotating shaft is connected to the motor, and the other end is connected to a stirring paddle. A sleeve is fitted onto the rotating shaft and rotatably connected to the mixing tank. A stirring frame is fixedly attached to the sleeve, and a scraper is fixedly attached to the stirring frame. One side of the scraper is in contact with the inner wall of the mixing tank. A fixing frame is fixedly attached to the mixing tank, and a gear is rotatably mounted on the fixing frame. An external gear ring is machined on the peripheral wall of the rotating shaft, and an internal gear ring is machined on the inner wall of the sleeve. The external and internal gear rings mesh with the two sides of the gear, respectively.

[0008] By adopting the above technical solution, the mixing frame and scraper rotate in the opposite direction of the mixing paddle inside the mixing tank along with the sleeve. The mixing frame can assist the mixing paddle in stirring the slurry in the mixing tank. The scraper scrapes the slurry against the inner wall of the mixing tank, which can reduce the adhesion of slurry to the inner wall of the mixing tank. After the slurry is stirred, the grouting pump is controlled to pump the slurry in the mixing tank out from the grouting pipe. When cleaning the mixing tank, water is added to the mixing tank and the motor is started. The scraper can scrape off the slurry adhering to the inner wall of the mixing tank, which is convenient for cleaning the grouting device.

[0009] Optionally, the stirring paddle includes a stirring plate, which is fixed to the rotating shaft, and the surface of the stirring plate is inclined in the direction of the rotating shaft.

[0010] By adopting the above technical solution, the inclined stirring plate can turn the slurry at the bottom of the mixing tank upward, so that the slurry forms a vortex in the mixing tank, ensuring uniform mixing of the slurry, reducing the deposition of slurry at the bottom of the mixing tank, reducing the adhesion of slurry to the inner wall of the mixing tank, and facilitating the cleaning of the grouting device.

[0011] Optionally, the scraper surface is curved into an arc.

[0012] By adopting the above technical solution, the scraper surface is arc-shaped, which can increase the contact area between the scraper and the inner wall of the mixing tank and improve the scraping efficiency of the scraper on the slurry.

[0013] Optionally, a rubber plate is fixedly attached to the scraper, and the rubber plate is in contact with the inner wall of the mixing tank.

[0014] By adopting the above technical solution, the rubber plate can increase the adhesion between the scraper and the inner wall of the mixing tank, reduce the gap between the scraper and the inner wall of the mixing tank, reduce the adhesion of slurry to the inner wall of the mixing tank, and facilitate the cleaning of the grouting device.

[0015] Optionally, a pusher plate is fixedly connected to the scraper, and the pusher plate is attached to the bottom of the mixing tank.

[0016] By adopting the above technical solution, the pusher plate rotates with the scraper, which can fit the rotating mixing tank to reduce slurry deposition at the bottom of the mixing tank, and at the same time scrape off the slurry adhering to the inner wall of the mixing tank, making it easier to clean the grouting device.

[0017] Optionally, at least two stirring plates are spaced apart, and one end of each stirring plate is fixedly connected to a stirring ring.

[0018] By adopting the above technical solution, the stirring ring can increase the overall structural strength of the stirring paddle, reduce the bending caused by the impact of the stirring plate on the slurry raw material when it rotates, and ensure the safety and stability of the stirring paddle operation.

[0019] Optionally, the base plate is equipped with casters, and at least two casters are spaced apart.

[0020] By adopting the above technical solution, the casters facilitate the movement of the grouting device, thereby improving the applicability of the grouting device on the construction site.

[0021] Optionally, a screw is threaded through the base plate, the screw is threaded to the base plate, one end of the screw is connected to a support foot, and the other end of the screw is fixed to a handwheel.

[0022] By adopting the above technical solution, rotating the handwheel drives the screw to rotate, causing the screw to drive the support leg to extend out of the bottom surface of the base plate and abut against the ground, which can improve the stability of the grouting device and ensure the safety and stability of the grouting device in use.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a stirring paddle, a stirring frame, and a scraper, the stirring frame can assist the stirring paddle in stirring the slurry in the mixing tank, and the scraper can scrape off the slurry by adhering to the inner wall of the mixing tank, which can reduce the adhesion of slurry to the inner wall of the mixing tank. When cleaning the mixing tank, add water into the mixing tank and start the motor. The scraper can scrape off the slurry adhering to the inner wall of the mixing tank, which is convenient for cleaning the grouting device.

[0025] 2. By incorporating a stirring ring, the overall structural strength of the stirring paddle is increased, reducing bending caused by the impact of the stirring plate on the slurry material during rotation, thus ensuring the safety and stability of the stirring paddle during operation;

[0026] 3. By setting up a pusher plate, it can fit the rotating mixing tank to reduce slurry deposition at the bottom of the mixing tank, and at the same time scrape off the slurry adhering to the inner wall of the mixing tank, making it easier to clean the grouting device.

A screw 12 is threaded through the base plate 1. Four screws 12 are spaced apart. The four screws 12 are arranged in a rectangle and are close to the four universal wheels 11 respectively. One end of the screw 12 extends out of the bottom surface of the base plate 1 and is hinged to a support leg 13. The other end of the screw 12 extends out of the top surface of the base plate 1 and is fixed to a handwheel by bolts.

[0033] Reference Figure 1 and Figure 2 A grouting pump 2 is installed on the base plate 1. The discharge end of the grouting pump 2 is connected to a grouting pipe 21. A mounting frame is welded on the base plate 1. The top of the mounting frame is located above the grouting pump 2. A mixing tank 3 is fixed to the top of the mounting frame by bolts. A feeding port is opened on the top of the mixing tank 3. The bottom surface of the mixing tank 3 is machined into a funnel shape. A discharge pipe is connected to the bottom of the mixing tank 3. The end of the discharge pipe away from the mixing tank 3 is connected to the feed end of the grouting pump 2. A motor 31 is installed on the top of the mixing tank 3. A rotating shaft 4 is rotatably installed inside the mixing tank 3. One end of the rotating shaft 4 extends out of the top of the mixing tank 3 and is connected to the output shaft of the motor 31 through a coupling. The other end of the rotating shaft 4 is located at the bottom of the mixing tank 3 and is equipped with a stirring paddle 5.

[0034] Reference Figure 2 A sleeve 6 is fitted inside the mixing tank 3, and the sleeve 6 is rotatably connected to the top of the mixing tank 3. A stirring frame 7 is installed on the peripheral wall of the sleeve 6. Two stirring frames 7 are spaced apart along the length of the sleeve 6. The ends of the two stirring frames 7 away from the sleeve 6 are connected to a scraper 8. Two scrapers 8 are spaced apart. The surface of the scraper 8 is curved along the height of the mixing tank 3. The scraper 8 is fixed to the stirring frame 7 by bolts. A rubber plate 81 is glued to the side of the scraper 8 away from the stirring frame 7. The side of the rubber plate 81 away from the scraper 8 abuts against the inner wall of the mixing tank 3. A pusher plate 9 is fixed to the bottom of the scraper 8 by bolts. The side wall of the pusher plate 9 is attached to the bottom of the mixing tank 3.

[0035] Reference Figure 2 and Figure 3 A fixing frame 61 is welded to the top of the mixing tank 3. The part of the fixing frame 61 away from the mixing tank 3 is sleeved on the rotating shaft 4 and located inside the sleeve 6. A gear 62 is rotatably arranged on the side of the fixing frame 61 away from the mixing tank 3. Three gears 62 are arranged at intervals along the peripheral wall of the rotating shaft 4. An external gear ring is machined on the peripheral wall of the rotating shaft 4 near the fixing frame 61. An internal gear ring is machined on the inner wall of the sleeve 6 near the fixing frame 61. The external gear ring meshes with the side of the gear 62 near the rotating shaft, and the internal gear ring meshes with the side of the gear 62 near the sleeve 6.

[0036] Reference Figure 2 The stirring paddle 5 includes a stirring plate 51, which is fixed to four spaced-apart surfaces by bolts. One side of the stirring plate 51 is inclined towards the rotation shaft 4. The four stirring plates 51 are spaced apart along the circumferential wall of the rotation shaft 4. The end of the four stirring plates 51 away from the rotation shaft 4 is connected to a stirring ring 52, which is welded to the stirring plate 51.

[0037] When using this grouting device, water and slurry raw materials are added into the mixing tank 3 through the feeding port. The motor 31 is started to drive the rotating shaft 4 and the stirring paddle 5 to rotate. At the same time, the outer gear ring on the peripheral wall of the rotating shaft 4 can drive the gear 62 to rotate, so as to drive the sleeve 6 to rotate inside the mixing tank 3. The stirring frame 7 and the scraper 8 rotate in the opposite direction of the stirring paddle 5 inside the mixing tank 3 along with the sleeve 6. The stirring frame 7 can assist the stirring paddle 5 in stirring the slurry in the mixing tank 3. The scraper 8 is in contact with the inner wall of the mixing tank 3 to scrape off the slurry. The surface of the scraper 8 is arc-shaped, which can increase the contact area between the scraper 8 and the inner wall of the mixing tank 3, improve the scraping efficiency of the scraper 8 on the slurry, and reduce the slurry adhesion to the inner wall of the mixing tank 3. After the slurry is stirred, the grouting pump 2 is controlled to pump the slurry in the mixing tank 3 out from the grouting pipe 21. When cleaning the mixing tank 3, water is added into the mixing tank 3 and the motor 31 is started. The scraper 8 can scrape off the slurry adhering to the inner wall of the mixing tank 3, which is convenient for cleaning the grouting device.

[0038] When using this grouting device, the casters 11 installed at the bottom of the base plate 1 facilitate the movement of the grouting device, improving its applicability on the construction site. By turning the handwheel, the screw 12 is rotated, causing the screw 12 to drive the support leg 13 to extend out of the bottom surface of the base plate 1 and abut against the ground, which improves the stability of the grouting device and ensures the safety and stability of its use.

[0039] When using this grouting device, as the agitator 5 rotates, the inclined agitator plate 51 can tumble the slurry at the bottom of the mixing tank 3 upwards, creating a vortex within the mixing tank 3. This ensures uniform mixing of the slurry, reduces slurry deposition at the bottom of the mixing tank 3, reduces slurry adhesion to the inner wall of the mixing tank 3, and facilitates cleaning of the grouting device. The agitator ring 52 increases the overall structural strength of the agitator 5, reduces bending caused by the agitator plate 51 impacting the slurry material during rotation, and ensures the safety and stability of the agitator 5 during operation.

[0040] When using this grouting device, the rubber plate 81 can increase the fit between the scraper 8 and the inner wall of the mixing tank 3, reduce the gap between the scraper 8 and the inner wall of the mixing tank 3, reduce the adhesion of grout to the inner wall of the mixing tank 3, and facilitate the cleaning of the grouting device.

[0041] When using this grouting device, the pusher plate 9 rotates with the scraper plate 8, which can fit the rotating mixing tank 3 to reduce slurry deposition at the bottom of the mixing tank 3, and at the same time scrape off the slurry adhering to the inner wall of the mixing tank 3, making it easy to clean the grouting device.
