Description

Technical Field

[0001] This application relates to the field of grouting equipment technology, and in particular to a grouting equipment and process for precast wall panels. Background Technology

[0002] With economic development and advancements in construction technology, many construction projects have seen significant improvements, especially in the fabrication and installation of prefabricated PC panels. Not only have these limitations been overcome, but the quality of PC panels has also steadily improved. BIM-adjustable prefabricated wall panels are a type of PC panel, and grouting is required when installing BIM-adjustable prefabricated wall panels.

[0003] The grouting head for simultaneous drilling and grouting, disclosed in publication number CN203129151U, includes a drill bit and a hollow drill rod. The drill bit is connected to the hollow drill rod, and a limiting pin is provided at the lower end of the drill rod. A steel ring is provided at the top of the drill bit, and the drill bit is hung on the limiting pin via the steel ring. The rear part of the drill bit is inserted into one end of the hollow drill rod. The drill bit is made of high-hardness cemented carbide. The front end of the hollow drill rod is inserted into the drill bit and sealed. Spray holes are distributed on the side wall of the hollow drill rod, and multiple grout outlet holes are provided at the lower part of the drill bit, arranged symmetrically. During the grouting process, the worker drills through the drill bit, and the grout entering the nozzle is sprayed out from the spray holes to grout into the precast wall panel.

[0004] When the flow rate of the slurry inside the nozzle is high, the inner wall of the nozzle will be impacted by the slurry, causing the nozzle to generate a recoil force away from the direction of the drill bit. There is a possibility that the hollow drill rod will be pushed out of the grouting hole, which is an area that needs improvement. Summary of the Invention

[0005] In order to improve the stability between the grouting head and the inner wall of the grouting hole during the grouting process and reduce the possibility of the grouting head being ejected from the grouting hole due to the reaction force applied to the grouting head, this application provides a grouting device and process for precast wall panels.

[0006] This application provides a grouting equipment and process for precast wall panels, which adopts the following technical solution:

[0007] A grouting device for precast wall panels includes a feeding device, a grouting pipe connected to the feeding device, and a grouting head connected to the outlet of the grouting pipe. A support rod is fixed on the inner wall of the grouting head, and a sliding block is slidably connected to the outer wall of the support rod. A drive rod is hinged to the outer wall of the sliding block, and a limit block is fixed on the outer wall of the drive rod. A sliding hole is provided on the side wall of the grouting head, and the limit block is slidably connected to the inner wall of the sliding hole. The outer wall of the limit block can abut against the inner wall of the grouting hole. A drive assembly for driving the sliding block to slide is provided on the outer wall of the grouting head.

[0008] By adopting the above technical solution, the worker inserts the grouting head into the grouting hole in advance. The drive component drives the sliding block to slide on the outer wall of the support rod. The sliding block pulls the drive rod, which drives the limiting block to slide in the sliding hole. The side of the limiting block away from the drive rod slides out of the sliding hole. The outer wall of the limiting block abuts against the inner wall of the grouting hole. Under the limitation of the limiting block, the grouting head is fixed in the grouting hole, and the position of the grouting head is limited, thereby improving the stability of the grouting head and reducing the possibility that the grouting head will be ejected from the grouting hole due to the recoil force during the injection of grout into the grouting hole.

[0009] Optionally, the drive assembly includes a rotating handle threadedly connected to the outer wall of the grouting head, a drive ring rotatably connected to the rotating handle, and a drive rod fixed to the drive ring, wherein the drive rod is hinged to the outer wall of the sliding block.

[0010] By adopting the above technical solution, the operator rotates the rotating handle, which slides on the outer wall of the grouting head. The drive ring rotates on the rotating handle, and under the drive of the rotating handle, the drive ring slides on the outer wall of the support ring, which drives the rod to move, thereby causing the sliding block to slide on the outer wall of the support rod.

[0011] Optionally, a blocking plate is slidably connected to the limiting block, a pushing plate is elastically connected to the side wall of the sliding block, and an opening rod is hinged to the outer wall of the pushing plate, the opening rod being hinged to the blocking plate.

[0012] By adopting the above technical solution, when grout is injected into the grouting hole, the grout exerts an impact force on the pushing plate, causing the pushing plate to slide on the outer wall of the support rod. The distance between the pushing plate and the sliding block decreases, driving the opening rod to push. The opening rod drives the blocking plate to slide on the sliding block, so that the end of the blocking plate abuts against the inner wall of the grouting hole. Under the limitation of the blocking plate, the engagement between the limiting block and the inner wall of the grouting hole is more stable, thereby making the engagement and fixation between the grouting head and the inner wall of the grouting hole more stable. After the grout injection is completed, under the action of the rebound force between the sliding block and the pushing plate, the pushing plate slides on the support rod, driving the end of the opening rod to slide. The opening rod drives the blocking plate to slide towards the inner cavity of the grouting head, so that the blocking plate leaves the inner wall of the grouting hole, thereby making it easier to pull the grouting head out of the grouting hole.

[0013] Optionally, a first receiving pipe is connected to the outlet of the grouting head, the first receiving pipe is rotatably connected to the grouting head, the outlet of the first receiving pipe is inclined, and a second receiving pipe is rotatably connected to the outlet of the first receiving pipe.

[0014] By adopting the above technical solution, the workers can rotate the first and second receiving pipes according to the orientation of the grouting hole opening, so that the outlet of the second receiving pipe faces different directions. This makes it easier for the workers to insert the first and second receiving pipes and the grouting head into the grouting hole, improving the flexibility of the grout outlet orientation and facilitating the connection between the grouting head and the grouting hole.

[0015] Optionally, the feeding device includes a frame, a hopper hinged to the side wall of the frame, a conveying screw rotatably connected to the hopper, and a material extraction component disposed at the outlet of the hopper. The outer wall of the hopper is provided with a linkage component for driving the conveying screw and the hopper to rotate.

[0016] By adopting the above technical solution, during the process of feeding material into the grouting head, the linkage component drives the conveying screw to rotate. The conveying screw transports the material in the hopper to the outlet of the hopper, and the material extraction component extracts the material in the hopper. When the hopper needs to be cleaned after the grout filling is completed, cleaning liquid is poured into the hopper to clean the inner wall of the hopper. The linkage component drives the hopper to rotate, causing the hopper to tilt, which facilitates the cleaning of the sewage in the hopper.

[0017] Optionally, a bracket is fixed to the outer wall of the hopper. The linkage component includes a rotating rod coaxially fixed to the conveying screw, a bearing rod rotatably connected to the outer wall of the hopper, a worm gear coaxially fixed to the rotating rod, and a worm wheel rotatably connected to the outer wall of the bracket. The worm wheel is rotatably connected to the bearing rod, the bearing rod is threaded to the frame, and the worm wheel meshes with the worm gear. A ratchet is coaxially fixed to the outer wall of the bearing rod, and a pawl is provided on the outer wall of the worm wheel. The ratchet engages with the pawl, and the bearing rod is coaxially fixed to the ratchet. A driving component for driving the rotating rod to rotate is provided on the outer wall of the conveying screw.

[0018] By adopting the above technical solution, when grout needs to be injected into the grouting head, the drive unit drives the rotating rod to rotate clockwise, and the rotating rod drives the conveying screw to rotate, transporting the grout in the hopper to the outlet of the hopper, thus facilitating the injection of grout into the grouting head; when grouting is completed and the hopper needs to be cleaned, cleaning fluid is poured into the hopper to clean the inner wall of the hopper; when the wastewater in the hopper needs to be emptied, the drive unit drives the rotating rod to rotate counterclockwise, and the rotating rod drives the worm to rotate. The worm and the worm wheel mesh, and the end of the pawl abuts against the inner wall of the ratchet, driving the ratchet to rotate. The ratchet drives the bearing rod to rotate, and the bearing rod rotates on the frame, increasing the distance between the support and the frame, raising one side of the hopper, making it easier to empty the wastewater in the hopper.

[0019] Optionally, the discharge port of the material extraction component is provided with a flow regulating component for controlling the flow rate of the slurry.

[0020] By adopting the above technical solution, when grout needs to be injected into a grouting hole with a large capacity, the flow regulating component controls the efficiency of the grout extraction component, thereby making the grout injection faster; when grout needs to be injected into a grouting hole with a small diameter, the flow regulating component controls the reduction of the extraction efficiency of the grout extraction component, thereby making it easier for the staff to control the extraction amount of the grout extraction component.

[0021] Optional, slurry flowability test: mix and stir the slurry, and test the flowability of the slurry using a ruler;

[0022] Adjust the grouting head and rotate the first and second receiving pipes so that the outlet of the grouting head tilts in different directions;

[0023] To fix the grouting head, insert the end of the grouting head into the gap between the precast wall panels, turn the rotating handle, and the rotating handle will drive the drive ring to slide on the outer wall of the grouting head, which will drive the driving rod to slide. The driving rod will drive the limiting block to slide, and the outer wall of the limiting block will abut against the inner wall of the precast wall panel, thus fixing the grouting head on the precast wall panel.

[0024] The slurry is injected by a drive unit that drives a rotating rod to rotate, which in turn drives a conveying screw to rotate. The extraction unit then extracts the slurry from the hopper, and the slurry enters the injection head and flows out from the outlet of the second receiving pipe.

[0025] By adopting the above technical solution, the staff pre-mixes and stirs the slurry, uses a ruler to check the slurry's fluidity, and manually rotates the first and second receiving pipes to match the outlet of the second receiving pipe with the inlet of the grouting hole. The second receiving pipe, the first receiving pipe, and the grouting head are then inserted into the grouting hole. By turning the rotating handle, the traction rod slides, causing the limiting block to slide, so that the outer wall of the limiting block abuts against the inner wall of the grouting hole. Under the constraint of the limiting block, the grouting head is fixed in the grouting hole. The drive unit is then activated, which drives the rotating rod to rotate. The rotating rod drives the conveying screw to rotate, and the conveying screw transports the slurry to the outlet of the hopper. The extraction unit then extracts the slurry from the hopper.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Before grouting, the grouting head is inserted into the grouting hole. The drive assembly drives the sliding block to slide, and the sliding block drives the drive rod to move. The drive rod drives the limiting block to slide outward of the grouting head. The outer wall of the limiting block abuts against the inner wall of the grouting hole. During the grouting process, an impact force is applied to the grouting head that is opposite to the embedding direction of the grouting hole. The setting of the limiting block limits the position of the grouting head and balances the impact force on the grouting head, thereby reducing the possibility of the grouting head being ejected from the grouting hole.

[0028] 2. During the process of injecting grout into the grouting head, the grout exerts a thrust on the outer wall of the pushing plate, which drives the opening rod to move. The opening rod drives the blocking plate to slide on the limiting block. The end of the blocking plate slides out of the limiting block, and the limiting plate abuts against the inner wall of the grouting hole, thus limiting the position of the grouting head. The impact force of the grout is cleverly used to improve the stability of the grouting head, thereby making the fixation of the grouting head more stable.

[0029] 3. Start the drive unit. The drive unit drives the rotating rod to rotate clockwise, which in turn drives the conveying screw to rotate, transporting the slurry in the hopper cavity to the hopper outlet. The drive unit then drives the rotating rod to rotate counterclockwise, which in turn drives the worm gear to rotate. The worm gear and worm wheel mesh, and the end of the pawl abuts against the inner wall of the ratchet, causing the ratchet to rotate. The ratchet then drives the bearing rod to rotate, which rotates on the frame, lifting one side of the hopper to facilitate the cleaning of wastewater in the hopper during the cleaning process.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] This application discloses a grouting equipment and process for precast wall panels.

[0039] Example 1:

[0040] Reference Figure 1 A grouting device for precast wall panels includes a grouting pipe 2 and a grouting head 3 connected to the outlet of the grouting pipe 2. A feeding device 1 for injecting grout into the grouting pipe 2 is provided at the end of the grouting pipe 2 away from the grouting head 3. During the grouting process, the operator inserts the grouting head 3 into the grouting hole, and the feeding device 1 injects grout into the grouting pipe 2. The grout in the grouting pipe 2 enters the grouting head 3 and then enters the grouting hole from the outlet of the grouting head 3.

[0041] Reference Figure 2 The feeding device 1 includes a frame 18, a hopper 19 hinged to the side wall of the frame 18, and a conveying screw 20 rotatably connected to the inner wall of the hopper 19. The lower end of the hopper 19 is hinged to the outer wall of the frame 18 via a connecting rod, and the lower end of the hopper 19 is connected to the outside. The feeding device 1 also includes a suction component 21 for extracting slurry from the hopper 19 at the lower outlet. In this application, the suction component 21 is preferably a screw pump. The inlet of the suction component 21 is connected to the outlet of the hopper 19, and the outlet of the suction component 21 is connected to the inlet of the grouting pipe 2. When the conveying screw 20 is rotated, it continuously delivers slurry to the outlet of the hopper 19. When the suction component 21 is activated, it draws the slurry from the hopper 19 into the grouting pipe 2.

[0042] Reference Figure 1 A linkage component 22 for driving the plastic screw to rotate is provided on the side of the hopper 19 away from the outlet. The end of the hopper 19 away from the material extraction component 21 is connected to the outside. The conveying screw 20 is fixed to the inner wall of the hopper 19 by bearings. A bracket 23 is welded and fixed to the outer wall of the hopper 19. A sliding groove is opened on the outer wall of the hopper 19. The linkage component 22 includes a rotating rod 24 fixed coaxially with the conveying screw 20, a bearing rod 25 with one end slidably connected to the inner wall of the sliding groove by a shaft pin, a worm 26 fixed coaxially on the rotating shaft, and a worm wheel 27 rotatably connected to the bracket 23. The worm wheel 27 meshes with the worm 26. A drive component 29 for driving the worm 26 to rotate is provided on the outer wall of the frame 18. In this application, the drive component 29 is preferably a drive motor. The rotating shaft of the drive component 29 is fixed coaxially with the worm 26 by a connecting rod. When the drive component 29 is started, the rotating shaft of the drive component 29 rotates, thereby driving the worm 26 to rotate.

[0043] Reference Figure 1and Figure 3 A ratchet 28 is coaxially fixed to the outer wall of the support rod 25 via a bearing. A pawl 33 is hinged to the outer wall of the bracket 23. The ratchet 28 and the pawl 33 engage. When the worm 26 rotates clockwise, it meshes with the worm wheel 27, and the pawl 33 slides against the ratchet 28. When the worm 26 rotates counterclockwise, it meshes with the worm wheel 27, causing the worm wheel 27 to rotate. The end of the pawl 33 abuts against the inner wall of the groove on the ratchet 28, driving the ratchet 28 to rotate. The ratchet 28 then drives the support rod 25 to rotate. The end of the support rod 25 furthest from the hopper 19 is threadedly connected to the frame 18. As the ratchet 28 drives the support rod 25 to rotate, the support rod 25 slides on the frame 18. Supported by the support rod 25, one side of the hopper 19 is lifted, making it easier for workers to pour the wastewater in the hopper 19 out of the hopper 19's inlet.

[0044] Reference Figure 1 The outlet of the material extraction component 21 is provided with a flow regulating component 30 for controlling the flow rate of the slurry at the outlet of the material extraction component 21. In this application, the flow regulating component 30 is preferably a flow controller. The flow regulating component 30 is electrically connected to the material extraction component 21, and the flow rate of the slurry is controlled by the flow regulating component 30.

[0045] Reference Figure 4 and Figure 5 A support rod 4 is coaxially fixed on the inner wall of the grouting head 3. A sliding block 5 is slidably connected to the outer wall of the support rod 4. Several drive rods 6 are hinged to the outer wall of the sliding block 5. In this application, three drive rods 6 are preferred. A limit block 7 is hinged to the end of each drive rod 6 away from the sliding block 5. Three sliding holes 8 are opened on the outer wall of the grouting head 3. The sliding holes 8 are evenly spaced along the diameter direction of the grouting head 3. The limit blocks 7 are arranged in a one-to-one correspondence with the sliding holes 8. The limit blocks 7 are slidably connected in the sliding holes 8. A drive assembly 9 for driving the sliding block 5 to slide is provided on the outer wall of the grouting head 3. The drive assembly 9 drives the sliding block 5 to slide toward the end of the grouting head 3 away from the grouting pipe 2, which in turn drives the drive rod 6 to slide. The drive component 29 drives the limiting block 7 to slide away from the inner cavity of the grouting head 3, so that the outer wall of the limiting block 7 abuts against the inner wall of the grouting hole, thus restricting the grouting head 3 to the inner wall of the grouting hole, thereby reducing the possibility of the grouting head 3 being ejected from the grouting hole during the grouting process.

[0046] Reference Figure 4 The outer wall of the grouting head 3 has three strip grooves 34. The drive assembly 9 includes a rotating handle 10 threadedly connected to the outer wall of the grouting head 3. The side wall of the rotating handle 10 has an installation groove. The drive assembly 9 also includes a drive ring 11 rotatably connected to the inner wall of the installation groove and a drive rod 12 welded and fixed to the outer wall of the drive ring 11. (Refer to...) Figure 5One end of the drive ring 11 is hinged to a connecting rod 31, which passes through the strip groove 34. The end of the connecting rod 31 away from the drive rod 12 is hinged to the outer wall of the sliding block 5. When the rotating handle 10 is turned, the rotating handle 10 drives the drive rod 12 to slide, and the drive rod 12 drives the connecting rod 31 to move. The sliding of the connecting rod 31 drives the sliding block 5 to slide.

[0047] Reference Figure 5 A push plate 14 is slidably connected to the outer wall of the support rod 4. Several opening rods 15 are hinged to the outer wall of the push plate 14. In this application, three opening rods 15 are preferred. One end of the opening rod 15 is hinged to the outer wall of the push plate 14, and the other end of the opening rod 15 is hinged to a blocking plate 13. A through groove is provided on the side wall of the limiting block 7. The blocking plate 13 is slidably connected to the inner wall of the through groove. An elastic element 32 is provided on the outer wall of the push plate 14 to make the push plate 14 return to its original position. In this application, the elastic element 32 is preferably a spring. One end of the elastic element 32 is welded and fixed to the side wall of the push plate 14, and the other end is welded and fixed to the outer wall of the sliding block 5. When grout is injected into the grouting hole through the grouting head 3, the grout exerts an impact force on the outer wall of the pushing plate 14, causing the pushing plate 14 to slide. The pushing plate 14 drives the opening rod 15 to move, causing the blocking plate 13 to slide, so that the end of the blocking plate 13 is inserted into the inner wall of the grouting hole, limiting the position of the grouting head 3, thereby making the fixation of the grouting head 3 more stable.

[0048] Reference Figure 4 The outlet of the grouting head 3 is connected to a first receiving pipe 16, which is rotatably connected to the grouting head 3. The end of the first receiving pipe 16 away from the grouting head 3 is inclined. The end of the first receiving pipe 16 away from the grouting head 3 is connected to a second receiving pipe 17, which is rotatably connected to the first receiving pipe 16. In this application, there are two of each of the first receiving pipe 16 and the second receiving pipe 17. The operator can manually rotate the first receiving pipe 16 and the second receiving pipe 17 so that the orientation of the first receiving pipe 16 and the second receiving pipe 17 is the same as the orientation of the grouting hole, which makes it easier for the operator to insert the grouting head 3 into the grouting hole.

[0049] According to Embodiment 1 of this application, the implementation principle of a grouting device for a precast wall panel is as follows: grout is pre-filled into the hopper 19, the first receiving pipe 16 and the second receiving pipe 17 are rotated so that the bending direction of the first receiving pipe 16 and the second receiving pipe 17 is oriented towards the direction that facilitates insertion into the grouting hole, the first receiving pipe 16, the second receiving pipe 17 and the grouting head 3 are all inserted into the grouting hole, the rotating handle 10 is turned, the rotating handle 10 drives the driving rod 6 to slide, the driving rod 6 drives the sliding block 5 to slide, the sliding block 5 drives the limiting block 7 to slide, so that the limiting block 7 abuts against the inner wall of the grouting hole, and the grouting head 3 is fixed in the grouting hole. The driving component 29 drives the rotating rod 24 to rotate, and the rotating rod 24 drives the conveying screw 20 to rotate. The conveying screw 20 transports the slurry to the outlet of the hopper 19. The suction component 21 is activated, and the suction component 21 draws the slurry in the hopper 19 into the grouting pipe 2. The slurry enters the grouting head 3 along the grouting pipe 2 and enters the grouting hole from the outlet of the second receiving pipe 17.

[0050] Example 2:

[0051] Example 2 employs the grouting process of a precast wall panel grouting equipment as described in Example 1, including the following steps:

[0052] Reference Figure 5 The fluidity of the slurry is tested by mixing the slurry with a mixer, taking a small amount of slurry with a sampler and dropping it onto a horizontal surface, and measuring the fluidity of the slurry with a ruler.

[0053] Adjust the grouting head 3 and rotate the first receiving pipe 16 and the second receiving pipe 17 so that the first receiving pipe 16 and the second receiving pipe 17 are oriented in a direction that facilitates insertion into the grouting hole.

[0054] To fix the grouting head 3, insert the first receiving pipe 16, the second receiving pipe 17 and the grouting head 3 into the grouting hole, turn the rotating handle 10, the rotating handle 10 drives the driving rod 12 to slide, and drives the sliding block 5 to slide. Under the drive of the sliding block 5, the limiting block 7 slides away from the inner cavity of the grouting head 3. The outer wall of the limiting block 7 abuts against the inner wall of the grouting hole, thereby fixing the grouting head 3 in the grouting hole.

[0055] When the slurry is injected, the drive unit 29 is activated. The drive unit 29 drives the worm gear 26 to rotate clockwise. The worm gear 26 drives the rotating rod 24 to rotate, which in turn drives the conveying screw 20 to rotate. The conveying screw 20 transports the slurry in the hopper 19 to the outlet of the hopper 19. The suction unit 21 is activated. The suction unit 21 draws the slurry in the hopper 19 into the grouting pipe 2. The slurry enters the grouting head 3 through the grouting pipe 2 and enters the grouting hole from the outlet of the second receiving pipe 17.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
