Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction grouting technology, specifically a pile foundation construction grouting device with a mixing mechanism. Background Technology

[0002] Pile foundation construction refers to the process of constructing the foundation of a building. A pile foundation consists of piles and pile caps. Pile construction methods are divided into two main categories: precast piles and cast-in-place piles. Cast-in-place piles are constructed by drilling holes in place and pouring in concrete or reinforced concrete. Currently, some challenging problems are often encountered during grouting operations in pile foundation construction. For example, if the mortar remains inside the device for a slightly longer period, it is prone to solidification. Once the mortar solidifies, it will not only block the delivery pipes, severely affecting the smoothness of subsequent grouting, but may also lead to uneven grouting and reduce the overall quality of the pile foundation.

[0003] According to the patent application published on the Internet, a pile foundation grouting device with a mixing mechanism (authorization announcement number: CN221608878U) is described as including a "material box, grout delivery pipe, base" etc., to realize the grouting work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This pile foundation grouting device with a mixing mechanism uses a material box, grout delivery pipe, and base to perform grouting. During use, the grout is mixed in the material box. However, the grout is in a sealed state. When the inside of the material box needs to be cleaned after grouting, this device is not convenient for thorough cleaning, which causes the grout to solidify and affect subsequent grout delivery. Furthermore, it cannot add water, thus affecting the grouting quality. Therefore, this device needs to be improved. Utility Model Content

A stirring shaft is fixedly connected to the periphery of the rotating rod. A stirring blade is fixedly connected to the bottom of the rotating rod. A second servo motor is fixedly connected to the left side of the storage tank. A rotating shaft is fixedly connected to the right side of the second servo motor. An auger is fixedly connected to the periphery of the rotating shaft.

[0009] Preferably, the sealing cover is slidably connected to the inside of the fixing frame, the bottom of the sealing cover is in contact with the top of the storage box, the diverter is fixedly connected to the inside of the sealing cover, and the pump body is fixedly connected to the top of the sealing cover, so as to facilitate the sealing of the top of the storage box under the action of the sealing cover, and at the same time facilitate the subsequent cleaning of its interior.

[0010] Preferably, the rotating rod is rotatably connected inside the sealing cover, and the rotating shaft is rotatably connected inside the storage tank, so as to facilitate the rotation of the stirring shaft and stirring blades by the rotating rod.

[0011] Preferably, the left side of the storage box is fixedly connected to the right side of the handrail, the bottom of the storage box is inclined, and a feed inlet is provided at the bottom of the storage box. The feed inlet is rectangular, so that the mixed slurry can enter the auger conveyor through the feed inlet.

[0012] Preferably, there are two sets of fixing frames and cylinders, which are symmetrically distributed on the front and rear sides of the storage box. By setting two sets, the stability of the movement of the sealing cover can be guaranteed.

[0013] Preferably, the fixing mechanism includes a first mounting frame, which is fixedly connected to the front side of the storage box. A connecting frame is fixedly connected to the top of the first mounting frame, and a second mounting frame is fixedly connected to the top of the connecting frame. An insert block is slidably connected inside the second mounting frame, and a fixing rod is fixedly connected to the inner side of the insert block. The fixing rod is inserted into the inside of the second mounting frame, and a fixing plate is fixedly connected to the front side of the insert block. A limit pin is inserted into the inside of the fixing plate.

[0014] Preferably, the first mounting bracket and the second mounting bracket are the same size and shape, and the second mounting bracket is fixedly connected to the front side of the storage box, so as to ensure the stability of the plug under different working conditions through the first mounting bracket and the second mounting bracket.

[0015] Compared with the prior art, this utility model provides a pile foundation grouting device with a mixing mechanism, which has the following beneficial effects:

[0016] 1. This pile foundation grouting device with a mixing mechanism first moves the storage tank to the vicinity of the pile foundation construction area under the action of the handle and moving wheels. Under the action of the cylinder, the sealing cover is placed on top of the storage tank, and the grouting pipe is placed on top of the pile foundation to be grouted. At this time, the cement truck transporting the grout can transport the grout through the sealing cover into the storage tank. The first servo motor drives the rotating rod, mixing shaft and mixing blade to rotate, stirring the grouting material in the storage tank to make the material evenly mixed. This avoids the impact of excessive cement truck transportation time on the subsequent construction quality. At the same time, the water tank adds water to the storage tank through the pump body, delivery pipe, distributor and nozzle. The material ratio can be adjusted as needed to meet the requirements of different construction conditions. This also avoids the solidification phenomenon caused by excessive waiting time when the cement truck transports the grout into the storage tank, thus improving the construction quality. After mixing, the grout enters the position of the auger through the rectangular feed port at the bottom of the storage tank.

[0017] 2. This pile foundation grouting device with a mixing mechanism, through a fixed mechanism, allows the storage box to be moved to the vicinity of the pile foundation construction site when the grout needs to be mixed during pile foundation construction. The moving wheels then slide the insert and fixing rod from the inside of the second mounting frame to the inside of the first mounting frame, and the fixing rod is inserted into the first mounting frame. This changes the placement of the fixing plate, making the bottom of the fixing plate contact the ground. Simultaneously, the limiting pin is inserted into the fixing plate, and an external striking device can then insert the limiting pin into the soil near the pile foundation. This securely fixes the storage box to the construction ground, preventing equipment shaking during grouting from affecting construction quality, ensuring construction stability and safety, and also limiting the movement of the moving wheels.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-7This utility model provides a technical solution: a pile foundation construction grouting device with a mixing mechanism, including a moving wheel 1, a grouting mechanism 2 on the top of the moving wheel 1, a handrail 3 on the left side of the grouting mechanism 2, and a fixing mechanism 4 on the front and rear sides of the grouting mechanism 2.

[0032] The grouting mechanism 2 includes a storage box 21, which is fixedly connected to the top of the moving wheel 1. A grouting pipe 22 is fixedly connected to the right side of the storage box 21. A fixing frame 24 is fixedly connected to the rear side of the storage box 21. A cylinder 25 is fixedly connected to the top of the fixing frame 24. A sealing cover 23 is fixedly connected to the bottom of the cylinder 25. The sealing cover 23 is located on the top of the storage box 21. A water tank 26 is fixedly connected to the top of the sealing cover 23. A conveying pipe 29 is fixedly connected to the right side of the water tank 26. A distributor 291 is fixedly connected to the bottom of the conveying pipe 29. The distributor 291 has a bottom... A nozzle 292 is fixedly connected to the main body. A pump body 28 is fixedly connected to the periphery of the conveying pipe 29. A first servo motor 27 is fixedly connected to the top of the sealing cover 23. A rotating rod 294 is fixedly connected to the bottom of the first servo motor 27. A stirring shaft 293 is fixedly connected to the periphery of the rotating rod 294. A stirring blade 295 is fixedly connected to the bottom of the rotating rod 294. A second servo motor 296 is fixedly connected to the left side of the storage tank 21. A rotating shaft 297 is fixedly connected to the right side of the second servo motor 296. An auger 298 is fixedly connected to the periphery of the rotating shaft 297.

[0033] The sealing cover 23 is slidably connected to the inside of the fixed frame 24. The bottom of the sealing cover 23 is in contact with the top of the storage box 21. The distributor 291 is fixedly connected to the inside of the sealing cover 23. The pump body 28 is fixedly connected to the top of the sealing cover 23, which facilitates sealing the top of the storage box 21 under the action of the sealing cover 23, and also facilitates subsequent cleaning of its interior. The rotating rod 294 is rotatably connected to the inside of the sealing cover 23, and the rotating shaft 297 is rotatably connected to the inside of the storage box 21, which facilitates driving the stirring shaft 293 and the stirring blade 295 to rotate through the rotating rod 294.

[0034] The storage box 21 is fixedly connected to the right side of the handrail 3 on the left side. The bottom of the storage box 21 is inclined and has a feed inlet at the bottom. The feed inlet is rectangular, which makes it easy for the mixed slurry to enter the conveying position of the auger 298 through the feed inlet. There are two sets of fixing frames 24 and cylinders 25. The two sets of fixing frames 24 and cylinders 25 are symmetrically distributed on the front and rear sides of the storage box 21. By setting two sets, the stability of the movement of the sealing cover 23 can be guaranteed.

[0035] Example 2

[0036] Please see Figure 1-7Furthermore, based on Embodiment 1, the fixing mechanism 4 further includes a first mounting frame 41, which is fixedly connected to the front side of the storage box 21. A connecting frame 42 is fixedly connected to the top of the first mounting frame 41, and a second mounting frame 43 is fixedly connected to the top of the connecting frame 42. An insert block 44 is slidably connected inside the second mounting frame 43. A fixing rod 45 is fixedly connected to the inner side of the insert block 44 and inserted into the inside of the second mounting frame 43. A fixing plate 46 is fixedly connected to the front side of the insert block 44, and a limit pin 47 is inserted into the inside of the fixing plate 46.

[0037] The first mounting bracket 41 and the second mounting bracket 43 are the same size and shape. The second mounting bracket 43 is fixedly connected to the front side of the storage box 21, so as to ensure the stability of the insert block 44 under different working conditions through the first mounting bracket 41 and the second mounting bracket 43.

[0038] In actual operation, when this device is used, the storage box 21 is first moved to the vicinity of the pile foundation construction by the action of the handrail 3 and the moving wheel 1. At the same time, the grouting pipe 22 is placed on the top of the pile foundation that needs to be grouted. The insert block 44 and the fixing rod 45 are slidably connected from the inside of the second mounting frame 43 to the inside of the first mounting frame 41, and the fixing rod 45 is inserted into the inside of the first mounting frame 41. This changes the placement position of the fixing plate 46, so that the bottom of the fixing plate 46 contacts the ground. At the same time, the limiting pin 47 is inserted into the inside of the fixing plate 46. The limiting pin 47 can be inserted into the soil near the pile foundation by external hammering equipment. This can fix the storage box 21 firmly on the construction ground, prevent the equipment from shaking during the grouting process, and ensure the stability and safety of the construction. At the same time, it can also limit the movement of the moving wheel 1.

[0039] After fixing, the sealing cover 23 is positioned on top of the storage tank 21 by the cylinder 25, allowing the cement truck transporting the grout to deliver the grout through the sealing cover 23 into the storage tank 21. The first servo motor 27 drives the rotating rod 294, stirring shaft 293, and stirring blade 295 to rotate, stirring the grouting material in the storage tank 21 to ensure uniform mixing and prevent the cement truck from affecting the subsequent construction quality due to excessive delivery time. At the same time, the water tank 26, through the pump body 28, delivery pipe 29, distributor 291, and nozzle, delivers the grout. Water is added to the storage tank 21 by 292. The material ratio can be adjusted as needed to meet the requirements of different construction conditions. At the same time, it can avoid solidification caused by the cement truck waiting too long to deliver the slurry to the storage tank 21, thus improving the quality of construction. After mixing, the slurry will enter the position of the auger 298 through the rectangular inlet at the bottom of the storage tank 21. The second servo motor 296 drives the rotating shaft 297 and the auger 298 to rotate, so that the slurry can be delivered to the pile foundation through the grouting pipe 22 for grouting.

[0040] After grouting is completed, the sealing cover 23 can be moved away from the top of the storage box 21 by the action of the cylinder 25, which makes it convenient for the staff to carry out a thorough cleaning of the inside of the storage box 21, and to avoid the solidification of the grout affecting the subsequent grouting work. At the same time, the limit pin 47 can be removed, and the insert block 44 and the fixing rod 45 can be put from the first mounting frame 41 into the second mounting frame 43. In the process of use, the two sets of cylinders 25, the first servo motor 27 and the second servo motor 296 can be connected to the same controller to ensure the coordinated work between the equipment. The controller is existing technology, and those skilled in the art know that only the specific operation steps and usage methods of the controller are needed. The moving wheel 1 of this invention has a steering function.
