Description

Technical Field

[0001] This utility model relates to the field of grouting devices, and in particular to a grouting device for foundation seepage prevention construction. Background Technology

[0002] In basic seepage prevention construction, grouting technology is widely used in engineering fields such as foundation reinforcement, tunnel waterproofing, and foundation pit support. As a core piece of equipment, the performance of the grouting device directly affects the mixing uniformity, conveying efficiency, and final seepage prevention effect of the grout. Currently, traditional grouting devices usually use static storage silos or simple conveying pipelines. During storage or transportation, the grout may stratify or locally solidify due to prolonged static placement. In particular, cement-based grout is prone to clogging the pipeline due to initial setting, seriously affecting the continuity of construction and the quality of grouting.

[0003] Existing devices often suffer from insufficient material pressure during discharge. For example, a grouting device for foundation seepage prevention construction disclosed in application number CN202321752447.5 relies primarily on the gravity of the grout itself for output. This results in significant pressure drop during grout transport, leading to low discharge efficiency, incomplete grouting, and difficulty in meeting the requirements of high-permeability strata or high-flow-rate construction. Furthermore, pulsed grout discharge is prone to occur when the grout viscosity changes, exacerbating the unevenness of the seepage prevention layer. Therefore, this solution proposes a grouting device for foundation seepage prevention construction. Summary of the Invention

[0004] This utility model proposes a grouting device for basic seepage prevention construction, which solves the problem of slow material discharge speed caused by insufficient output pressure during the material conveying process of existing grouting devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grouting device for basic seepage prevention construction includes a base and a storage tank mounted on top of the base. Casters are installed at the bottom of the base, and a handrail is installed on one side of the top of the base. The storage tank has a feed inlet at its top, and a sealing cap for sealing the feed inlet is installed on the top surface of the storage tank. The storage tank is equipped with: A stirring mechanism, comprising a stirring shaft rotatably connected to the inner wall of the top of a storage tank and a drive component mounted on the top of the storage tank for driving the stirring shaft to rotate; The conveying mechanism includes a conveying pipe installed at the bottom of the storage tank, an auger rotatably connected inside the conveying pipe for conveying slurry, and a discharge pipe installed at the bottom of one side of the storage tank for connecting the conveying pipe to the inside of the storage tank. The auger is connected to the stirring shaft via a transmission component. A pressurizing mechanism is installed on top of the storage tank and is connected to the stirring shaft via a drive mechanism. When the stirring shaft rotates in the forward direction, it drives the pressurizing mechanism to operate, so as to pressurize the storage tank while the conveying mechanism outputs the slurry from the storage tank.

[0006] The above technical solution not only drives the auger to rotate through the rotation of the stirring shaft, thereby achieving the purpose of mixing and outputting slurry at the same time, but also drives the pressurization component to operate through the rotation of the rotating shaft while outputting slurry, thereby pressurizing the storage tank and accelerating the output speed of slurry.

[0007] As a further improvement to the above solution, a connecting shaft that is rotatably connected to the top surface of the storage tank is fixed on one side of the bottom surface of the sealing cover, and multiple locking bolts are threaded onto the top surface of the sealing cover. Multiple fixing holes for connecting the locking bolts are opened on the top surface of the storage tank.

[0008] As a further improvement to the above solution, the stirring shaft includes a rotating shaft rotatably connected to the inner wall of the top of the storage tank and a plurality of stirring rods fixed to the outer periphery of the rotating shaft. The driving component includes a mounting bracket installed on the top of the storage tank and a stirring motor installed on its top surface. The top of the rotating shaft extends above the storage tank and is drively connected to the output shaft of the stirring motor.

[0009] As a further improvement to the above solution, the bottom inner wall of the storage tank is a conical structure with the top protruding upwards, and a scraper is fixed on the outer periphery of the rotating shaft, with the bottom edge of the scraper fitting against the bottom inner wall of the storage tank.

[0010] As a further improvement to the above solution, the pressurization mechanism includes an air cylinder installed on the top surface of the storage tank, a driven gear rotatably connected to the top surface of the storage tank, a driving gear movably sleeved on the outer circumference of the rotating shaft, and a fixed sleeve rotatably sleeved on the outer circumference of the rotating shaft. The bottom of the fixed sleeve is fixedly connected to the top surface of the driving gear. A one-way locking assembly is provided between the inner ring of the driving gear and the rotating shaft to drive the driving gear to rotate only when the rotating shaft rotates forward. The driving gear meshes with the driven gear. A connecting rod is hinged at a position off-center from the top surface of the driven gear. A piston plate is installed inside the air cylinder. A piston rod is fixed on one side of the piston plate. One end of the piston rod extends to the outside of the air cylinder and is hinged to the connecting rod. An air intake pipe and an air outlet pipe communicating with the inside of the storage tank are installed on the air cylinder. A one-way valve is installed on both the air intake pipe and the air outlet pipe.

[0011] As a further improvement to the above solution, multiple sets of the one-way snap-fit ​​assembly are provided. The outer circumference of the rotating shaft is provided with multiple buffer holes for installing the one-way snap-fit ​​assembly. The one-way snap-fit ​​assembly includes a snap block and a spring disposed in the buffer hole. One end of the spring is fixedly connected to one end of the snap block, and the other end of the spring is fixedly connected to the inside of the buffer hole. The other end of the snap block has a right-angled triangular structure and abuts against the inner ring of the drive gear. The inner ring of the drive gear is provided with multiple snap holes for snapping the snap block.

[0012] As a further improvement to the above solution, the transmission component includes a transmission shaft rotatably connected to one end of the conveying pipe and fixed to one end of the auger, and a driven bevel gear fixed to the other end of the transmission shaft. The bottom of the shaft extends to the bottom of the storage tank and is fixed with a driving bevel gear that meshes with the driven bevel gear.

[0013] As a further improvement to the above solution, a detachable connecting pipe fitting is also included at the outlet of the conveying pipe. The connecting pipe fitting includes a fixed pipe threaded onto the outer periphery of the outlet of the conveying pipe, a flexible hose fixed to one end of the fixed pipe, and a discharge nozzle fixed to the other end of the flexible hose.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the cooperation between the stirring mechanism and the conveying mechanism, the auger can be reversed when the stirring shaft rotates forward, so that the slurry in the storage tank can be output through the conveying pipe while stirring the slurry in the storage tank. When the stirring shaft rotates in reverse, it drives the auger to rotate forward. At this time, the stirring shaft stirs the slurry in the storage tank, but the auger will not output the slurry in the storage tank.

[0015] 2. By setting up a pressurizing mechanism, the driven gear can be driven to rotate when the stirring shaft rotates forward, thereby pressurizing the storage tank with an air cylinder. This allows the slurry in the storage tank to enter the conveying pipe more quickly and stably under pressure when the slurry is output.

[0016] 3. The connection fittings allow the slurry output from the conveying pipe to be conveniently discharged from different directions, making it easy for operators to adjust the output angle and position of the slurry according to actual needs. Attached Figure Description

Detailed Implementation

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example 1

[0021] Please combine Figures 1-6 This embodiment of a grouting device for basic seepage prevention construction includes a base 1 and a storage tank 2 installed on the top of the base 1. Casters are installed at the bottom of the base 1, and a handrail 11 is installed on one side of the top of the base 1. The storage tank 2 is used to store grout, and the handrail 11 is provided to facilitate the movement of the entire device.

[0022] The storage tank 2 has a feed inlet 12 at the top. A sealing cover 3 for sealing the feed inlet 12 is installed on the top surface of the storage tank 2. A connecting shaft that is rotatably connected to the top surface of the storage tank 2 is fixed to one side of the bottom surface of the sealing cover 3. Multiple locking bolts 4 are threadedly connected to the top surface of the sealing cover 3. Multiple fixing holes 13 for connecting the locking bolts 4 are opened on the top surface of the storage tank 2. The inner wall of the fixing hole 13 has threads that engage with the locking bolts 4. After one end of the locking bolt 4 is tightened inside the fixing hole 13, the sealing cover 3 is pressed against the top surface of the storage tank 2, so that the sealing cover 3 can seal the feed inlet 12. Conversely, after the locking bolts 4 are unscrewed from the fixing holes 13, the sealing cover 13 is rotated to make it offset from the feed inlet 12, so that the slurry can be fed into the storage tank 2 from the feed inlet 12.

[0023] Storage tank 2 is equipped with: The stirring mechanism includes a stirring shaft rotatably connected to the inner wall of the top of the storage tank 2 and a driving component mounted on the top of the storage tank 2 for driving the stirring shaft to rotate. The stirring shaft includes a rotating shaft 14 rotatably connected to the inner wall of the top of the storage tank 2 and a plurality of stirring rods 16 fixed on the outer periphery of the rotating shaft 14. The driving component includes a mounting bracket 5 mounted on the top of the storage tank 2 and a stirring motor 6 mounted on its top surface. The top of the rotating shaft 14 extends above the storage tank 2 and is drivenly connected to the output shaft of the stirring motor 6. After the stirring motor 6 rotates, it drives the rotating shaft 14 to rotate, thereby stirring the slurry in the storage tank 2, thus ensuring that the slurry is mixed evenly and preventing the slurry from solidifying.

[0024] The conveying mechanism includes a conveying pipe 9 installed at the bottom of the storage tank 2, an auger 27 rotatably connected inside the conveying pipe 9 for conveying slurry, and a discharge pipe 10 installed at the bottom of one side of the storage tank 2 for connecting the conveying pipe 9 to the inside of the storage tank 2. The auger 27 is connected to the stirring shaft via a transmission component, which includes a drive shaft 28 rotatably connected to one end of the conveying pipe 9 and fixed to one end of the auger 27, and a driven bevel gear fixed to the other end of the drive shaft 28. The bottom of the rotating shaft 14 extends to the bottom of the storage tank 2 and is fixed with a driving bevel gear that meshes with the driven bevel gear. When the rotating shaft 14 rotates forward, it drives the transmission shaft 28 to rotate in reverse, which in turn drives the auger 27 to rotate in reverse. After the slurry in the storage tank 2 enters the conveying pipe 9 through the discharge pipe 10, it will be gradually output to the outside of the conveying pipe 9 under the rotation of the rotating auger 27, thereby achieving the purpose of stirring and outputting slurry at the same time. This can effectively avoid clogging or solidification of slurry during output. Conversely, after the stirring motor rotates in reverse and drives the rotating shaft 14 to rotate in reverse, the auger 27 starts to rotate forward. At this time, the auger 27 will not output slurry outward, so that only the slurry in the storage tank 2 can be stirred.

[0025] A pressurizing mechanism is installed on the top of the storage tank 2 and drivenly connected to the stirring shaft. The pressurizing mechanism includes an air cylinder 7 installed on the top surface of the storage tank 2, a driven gear 19 rotatably connected to the top surface of the storage tank 2, a driving gear 17 movably sleeved on the outer circumference of the rotating shaft 14, and a fixed sleeve 18 rotatably sleeved on the outer circumference of the rotating shaft 14. The bottom of the fixed sleeve 18 is fixedly connected to the top surface of the driving gear 17. A one-way snap-fit ​​assembly is provided between the inner ring of the driving gear 17 and the rotating shaft 14 to allow for only one-way engagement on the rotating shaft 14. During forward rotation, the driving gear 17 rotates, meshing with the driven gear 19. A connecting rod 20 is hinged to the top surface of the driven gear 19 at a position off-center. A piston plate is installed inside the air cylinder 7, and a piston rod 21 is fixed to one side of the piston plate. One end of the piston rod 21 extends outside the air cylinder 7 and is hinged to the connecting rod 20. An air intake pipe 22 and an air outlet pipe 23 communicating with the inside of the storage tank 2 are installed on the air cylinder 7. Both the air intake pipe 22 and the air outlet pipe 23 are equipped with one-way valves. When the rotating shaft 14 rotates in the forward direction, the one-way locking component engages with the driving gear 17, thereby driving the driving gear 17 to rotate synchronously in the forward direction when the rotating shaft 14 rotates in the forward direction. When the driving gear 17 rotates in the forward direction, it drives the driven gear 19 to rotate in the reverse direction. After the driven gear 19 rotates in the reverse direction, it drives the piston rod 21 to move back and forth through the connecting rod 20, thereby driving the piston plate to move back and forth inside the air cylinder 7. This allows outside air to be drawn into the air cylinder 7 through the air intake pipe 22 and then discharged into the storage tank 2 through the air outlet pipe 23. This increases the pressure inside the storage tank 2 while the inlet 12 is sealed by the sealing cover 3, thereby accelerating the output of slurry from the storage tank 2. Conversely, when the rotating shaft 14 rotates in the reverse direction, the one-way locking component does not engage with the driving gear 17, so the driving gear 17 will not rotate when the rotating shaft 14 rotates in the reverse direction, and the pressurizing component will not operate. Therefore, the purpose of stopping pressurization into the storage tank 2 is achieved when the rotating shaft 14 rotates in the reverse direction.

[0026] In this embodiment: multiple sets of one-way snap-fit ​​components are provided. Multiple buffer holes 26 for installing the one-way snap-fit ​​components are opened on the outer periphery of the rotating shaft 14. Each one-way snap-fit ​​component includes a snap block 25 and a spring disposed within the buffer hole 26. One end of the spring is fixedly connected to one end of the snap block 25, and the other end of the spring is fixedly connected to the inside of the buffer hole 26. The other end of the snap block 25 has a right-angled triangular structure and abuts against the inner ring of the drive gear 17. The inner ring of the drive gear 17 has multiple snap holes 24 for snapping the snap block 25. Under the action of the spring, when one end of the snap block 25 snaps... After entering the slot 24, when the shaft 14 rotates forward, the inclined surface of the locking block 25 is opposite to the direction of the shaft 14's rotation. Thus, when the shaft 14 rotates forward, the locking block 25 can be inserted into the slot 24 to drive the drive gear 17 to rotate synchronously with the shaft 14. When the shaft 14 rotates in reverse, the inclined surface of the locking block 25 is in the same direction as its rotation. This causes the inclined surface of the locking block 25 to come into contact with the edge of the slot 24 and then exit from the slot 24, thus preventing the drive gear 25 from rotating. This achieves the purpose of driving the drive gear 17 to rotate in one direction only.

[0027] Example 2

[0028] Combination Figure 1 and Figure 6 This embodiment, based on embodiment 1, further improves upon the following: it also includes a detachable connecting fitting 8 connected to the outlet of the conveying pipe 9. The connecting fitting 8 includes a fixed pipe 83 threadedly fitted onto the outer periphery of the outlet of the conveying pipe 9, a flexible hose 82 fixed to one end of the fixed pipe 83, and a discharge nozzle 81 fixed to the other end of the flexible hose 82. The outer periphery of the conveying pipe 9 is provided with an external thread that is threadedly connected to the inner ring of the fixed pipe 83. After the fixed pipe 83 is fitted onto the outside of the outlet of the conveying pipe 9, the slurry can be conveniently output from different directions or different angles by adjusting the orientation of the discharge nozzle 81.
