Prefabricated component grouting equipment and grouting methods

Abstract

This invention discloses a grouting device and method for prefabricated components, relating to the field of grouting equipment. The device includes a fixed frame with a grout cylinder inside. Linear motors are fixed to the inner walls on both sides of the fixed frame. A hollow stirring shaft is mounted on the top of the fixed frame via a sealed bearing. The bottom end of the hollow stirring shaft extends into the grout cylinder and is fixed with two extension plates. Two sets of stirring rods are located inside the grout cylinder. This invention positions the bottom end of the hollow stirring shaft between the two sets of stirring rods. While the stirring rods are stirring, the conveyor shaft rotates, outputting the grout through the bottom end of the hollow stirring shaft. Because the bottom end of the hollow stirring shaft is located between the two sets of stirring rods, the grout is inevitably thoroughly stirred. Regardless of the relative positions of the grout cylinder and the hollow stirring shaft, the uniformity of the output grout is ensured, significantly improving the uniformity of the grout.

Description

Technical Field

[0001] This invention relates to the field of grouting equipment, specifically to grouting equipment and grouting methods for prefabricated components. Background Technology

[0002] Before construction begins, various building components, such as balconies, columns, and beams, can be prefabricated. Then, during construction, these components are assembled together, thereby improving construction efficiency.

[0003] The fabrication of building components involves pouring concrete grout into corresponding molds and allowing it to solidify and take shape. During the grouting process, specialized grouting equipment is required to evenly deliver the grout into the molds, such as the prefabricated component grouting equipment and grouting method disclosed in the prior art, CN116968179A.

[0004] In the existing technology, the slurry in each part of the lower hopper can be fully stirred by the up and down movement of the paddle fins. Therefore, the slurry uniformity is best at the part where the paddle fins are located. However, the slurry discharge part is always located at the bottom of the lower hopper. When the paddle fins are far away from the bottom of the lower hopper, the uniformity of the slurry at this point needs to be improved. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a grouting device and method for prefabricated components. By rotating the conveying shaft, grout is output outward through the bottom end of a hollow stirring shaft. Since the bottom end of the hollow stirring shaft is located between two sets of stirring rods, the grout is guaranteed to be fully stirred. Regardless of the relative position of the grout cylinder and the hollow stirring shaft, the uniformity of the output grout can be ensured, greatly improving the uniformity of the grout and effectively solving the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a prefabricated component grouting equipment, including a fixed frame, a grout cylinder inside the fixed frame, and linear motors fixedly installed on the inner walls of both sides of the fixed frame, with the moving parts of the two linear motors fixedly connected to both sides of the grout cylinder respectively.

[0007] The top of the fixed frame is equipped with a hollow stirring shaft through a sealed bearing. The bottom end of the hollow stirring shaft extends into the slurry cylinder and is fixedly equipped with two extension plates. The slurry cylinder is equipped with two sets of stirring rods, each set consisting of two rods. One set of stirring rods is fixedly installed at the outer end of the hollow stirring shaft, and the other set of two stirring rods are respectively fixedly installed at the outer ends of the two extension plates.

[0008] A second motor is fixedly installed at the bottom of the slurry cylinder. The output shaft of the second motor extends into the slurry cylinder and is fixedly installed with a conveying shaft. The top end of the conveying shaft extends into the hollow stirring shaft. The conveying shaft rotates in the opposite direction to the hollow stirring shaft.

[0009] Furthermore, a transfer cylinder is fixedly provided at the top of the fixed frame, and the top of the hollow stirring shaft is connected to the inside of the transfer cylinder, so as to input the slurry into the transfer cylinder;

[0010] The top of the adapter cylinder is fixedly equipped with a first motor. The output shaft of the first motor extends into the interior of the adapter cylinder and is fixedly equipped with a T-shaped connecting arm. The two branches at the bottom of the T-shaped connecting arm are fixedly connected to the inner wall of the hollow stirring shaft, thereby driving the hollow stirring shaft to rotate through the first motor.

[0011] Furthermore, a counterweight box is fixedly provided at the bottom of the fixed frame, and multiple rollers are fixedly provided at the bottom of the counterweight box. A water pipe is fixedly provided at the rear of the counterweight box, and one end of the water pipe is connected to a container filled with water.

[0012] Furthermore, two limiting posts are fixedly provided on the inner wall of the counterweight box, and the water pipe is located at the bottom of the limiting posts;

[0013] The counterweight box is equipped with a sealing plate inside. A sealing ring is fixedly provided at the outer end of the sealing plate, which contacts the inner wall of the counterweight box. Two connecting rods are fixedly provided at the top of the sealing plate, and the top of the connecting rods extends to the top of the counterweight box and is fixedly connected to the bottom of the slurry cylinder.

[0014] Furthermore, a conveying channel is fixedly provided on the front side of the adapter cylinder, a corrugated pipe is fixedly provided at the bottom end of the conveying channel, and a discharge assembly is provided at the bottom end of the corrugated pipe;

[0015] The material discharge assembly includes a material discharge box, a fixed plate is fixedly installed on the rear side of the material discharge box, and a hydraulic cylinder is fixedly installed at the bottom end of the conveying channel. One end of the piston rod of the hydraulic cylinder is fixedly connected to the top of the fixed plate, and the height of the material discharge assembly is controlled by the extension and retraction of the hydraulic cylinder.

[0016] Furthermore, the discharge assembly also includes a discharge pipe fixedly installed on the rear wall inside the discharge box. The top end of the discharge pipe is fixedly connected to the bottom end of the corrugated pipe. The front end of the discharge box has a notch, through which the slurry entering the discharge box finally overflows.

[0017] Furthermore, a fixed shaft is provided on the inner wall of the discharge box via a rotating shaft, and the rear side of the fixed shaft contacts the inner wall of the discharge box;

[0018] A base plate is fixedly provided on the front side of the fixed shaft, and a sealing strip is fixedly provided on the front end of the base plate. The outer end of the base plate and the sealing strip are in contact with the inner wall of the discharge box, thereby sealing the opening end of the discharge box.

[0019] Furthermore, the bottom of the discharge box is provided with two support plates via a damping shaft. One end of each support plate extends to the bottom of the base plate and contacts the base plate. The support plates limit and fix the base plate.

[0020] The present invention also includes a grouting method for prefabricated component grouting equipment, the specific steps of which are as follows:

[0021] S1: All raw materials for making slurry are put into the slurry cylinder. Then, the first motor is turned on, and the hollow stirring shaft is driven to rotate. The hollow stirring shaft drives the stirring rod to rotate inside the slurry cylinder. At the same time, the linear motor drives the slurry cylinder to move up and down and adjust the position of the stirring rod inside the slurry cylinder. In this way, the raw materials inside the slurry cylinder are initially and evenly stirred to form slurry.

[0022] S2: After the slurry is initially mixed evenly, the second motor is turned on. The second motor drives the conveyor shaft to rotate. The direction of rotation of the conveyor shaft is opposite to that of the hollow mixing shaft. Therefore, under the action of the conveyor shaft, the slurry inside the slurry cylinder is transported to the hollow mixing shaft and enters the transfer cylinder and conveying channel in sequence along the hollow mixing shaft. During the conveying process, the mixing work of the mixing rod continues.

[0023] S3: The slurry entering the conveying channel eventually enters the discharge pipe through the corrugated pipe, and then enters the discharge box. As the amount of slurry increases, the slurry inside the discharge box eventually overflows out through the gap. The discharge assembly is located at the mold of the assembled component, and the overflowing slurry falls into the mold.

[0024] S4: After the mold is filled, rotate the tray to remove it from the bottom of the base plate. The base plate will then be free of obstruction. At this time, rotate the fixed shaft downward to rotate the base plate, thereby opening the bottom of the discharge box and cleaning the residual slurry inside the discharge box.

[0025] Compared with the prior art, the present invention provides a grouting device and grouting method for prefabricated components, which has the following beneficial effects:

[0026] 1. By placing the bottom end of the hollow mixing shaft between two sets of mixing rods, the conveying shaft rotates while the mixing rods are mixing, and the slurry is output outward through the bottom end of the hollow mixing shaft. Since the bottom end of the hollow mixing shaft is located between the two sets of mixing rods, the slurry is guaranteed to be fully mixed. No matter how the relative position of the slurry cylinder and the hollow mixing shaft changes, the uniformity of the output slurry can be ensured, which greatly improves the uniformity of the slurry.

[0027] 2. By discharging the slurry into the discharge box, the slurry entering the discharge box will overflow from the gap. The overflowing slurry will fall into the mold, thus performing grouting. Compared with the slurry poured directly into the mold, the overflowing slurry has less kinetic energy and less impact force when poured, thereby further avoiding slurry splashing when pouring into the mold.

[0036] To make the technical means, creative features, and achieved objectives and effects of this invention readily understandable, the invention will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0037] like Figure 1-7As shown, the present invention provides a grouting device for prefabricated components, including a fixed frame 3, a grout cylinder 2 inside the fixed frame 3, and linear motors 7 fixedly installed on the inner walls of both sides of the fixed frame 3. The two sides of the grout cylinder 2 are respectively fixedly connected to the moving parts of the two linear motors 7.

[0038] The top of the fixed frame 3 is provided with a hollow stirring shaft 6 through a sealed bearing. The bottom end of the hollow stirring shaft 6 extends into the slurry cylinder 2 and is fixedly provided with two extension plates 14. The slurry cylinder 2 is provided with two sets of stirring rods 15. Each set of stirring rods 15 consists of two rods. One set of stirring rods 15 is fixedly provided at the outer end of the hollow stirring shaft 6, and the other set of two stirring rods 15 are respectively fixedly provided at the outer ends of the two extension plates 14.

[0039] The bottom end of the slurry cylinder 2 is fixedly provided with a second motor 13. The output shaft of the second motor 13 extends into the inside of the slurry cylinder 2 and is fixedly provided with a conveying shaft 12. The top end of the conveying shaft 12 extends into the inside of the hollow stirring shaft 6. The rotation direction of the conveying shaft 12 is opposite to that of the hollow stirring shaft 6.

[0040] During operation, the slurry is located inside the slurry cylinder 2. The hollow stirring shaft 6 drives the stirring rod 15 to rotate inside the slurry cylinder 2, thus stirring the slurry. Simultaneously, the mover of the linear motor 7 slides up and down on the stator, causing the slurry cylinder 2 to reciprocate. During this motion, the position of the stirring rod 15 inside the slurry cylinder 2 is adjusted to ensure uniform stirring of the slurry throughout the cylinder. During grouting, the second motor 13 is activated, driving the conveying shaft 12 to rotate and convey the slurry. The direction of rotation of shaft 12 is opposite to that of hollow mixing shaft 6, and the slurry inside the slurry cylinder 2 is fed into the hollow mixing shaft 6 through the bottom end of the hollow mixing shaft 6. The slurry is then output for grouting. While the slurry enters the hollow mixing shaft 6, the mixing work continues. Since the bottom end of the hollow mixing shaft 6 is located between the two sets of mixing rods 15, the slurry is guaranteed to be fully mixed. No matter how the relative positions of the slurry cylinder 2 and the hollow mixing shaft 6 change, the uniformity of the output slurry can be ensured, which greatly improves the uniformity of the slurry.

[0041] To drive the hollow stirring shaft 6 to rotate, such as Figure 1 , 4 As shown, the top of the fixed frame 3 is fixedly provided with a transfer cylinder 4, and the top of the hollow stirring shaft 6 is connected to the inside of the transfer cylinder 4, so as to input the slurry into the transfer cylinder 4;

[0042] The top of the adapter cylinder 4 is fixedly equipped with a first motor 5. The output shaft of the first motor 5 extends into the interior of the adapter cylinder 4 and is fixedly equipped with a T-shaped connecting arm 18. The two branches at the bottom of the T-shaped connecting arm 18 are fixedly connected to the inner wall of the hollow stirring shaft 6, thereby driving the hollow stirring shaft 6 to rotate through the first motor 5.

[0043] The slurry conveyed upward along the hollow stirring shaft 6 eventually enters the transfer cylinder 4. In order for the hollow stirring shaft 6 to rotate and perform stirring, the first motor 5 needs to be turned on. The first motor 5 drives the T-shaped connecting arm 18 to rotate. The bottom end of the T-shaped connecting arm 18 is connected to the inner wall of the hollow stirring shaft 6, thus driving the hollow stirring shaft 6.

[0044] As the slurry cylinder 2 moves up and down, the center of gravity of the equipment will change, such as Figure 1 , 7 As shown, a counterweight box 1 is fixedly provided at the bottom of the fixed frame 3, and multiple rollers are fixedly provided at the bottom of the counterweight box 1, so that the device can be moved easily. A water pipe is fixedly provided at the rear of the counterweight box 1, and one end of the water pipe is connected to a container filled with water.

[0045] Two limiting posts are fixedly provided on the inner wall of the counterweight box 1, and the water pipe is located at the bottom of the limiting posts;

[0046] The counterweight box 1 is provided with a sealing plate 16 inside. The outer end of the sealing plate 16 is fixed with a sealing ring that contacts the inner wall of the counterweight box 1. The top end of the sealing plate 16 is fixed with two connecting rods 17. The top end of the connecting rods 17 extends to the top of the counterweight box 1 and is fixedly connected to the bottom end of the slurry cylinder 2.

[0047] One end of the water pipe is connected to a container filled with water. During the reciprocating motion of the slurry cylinder 2, the slurry cylinder 2 drives the sealing plate 16 to reciprocate inside the counterweight box 1 via the connecting rod 17. When the slurry cylinder 2 moves upward, the sealing plate 16 also moves upward, thereby drawing water into the counterweight box 1 through the water pipe. The higher the height of the slurry cylinder 2, the more water is drawn into the counterweight box 1. The water increases the weight of the counterweight box 1 and lowers the center of gravity of the equipment, preventing the equipment from becoming unstable due to the rising height of the slurry cylinder 2.

[0048] When pouring the slurry into the mold, it is necessary to avoid slurry splashing as much as possible. Figure 1 , 6 As shown, a conveying channel 8 is fixedly provided on the front side of the adapter cylinder 4, a corrugated pipe 10 is fixedly provided at the bottom end of the conveying channel 8, and a discharge assembly 11 is provided at the bottom end of the corrugated pipe 10.

[0049] The discharge assembly 11 includes a discharge box 1101, a fixing plate 1104 is fixedly provided on the rear side of the discharge box 1101, and a hydraulic cylinder 9 is fixedly provided at the bottom end of the conveying channel 8. One end of the piston rod of the hydraulic cylinder 9 is fixedly connected to the top end of the fixing plate 1104, and the height of the discharge assembly 11 is controlled by the extension and retraction of the hydraulic cylinder 9.

[0050] The discharge assembly 11 also includes a discharge pipe 1107 fixedly installed on the rear wall inside the discharge box 1101. The top end of the discharge pipe 1107 is fixedly connected to the bottom end of the corrugated pipe 10. The front end of the discharge box 1101 has a notch 1102, through which the slurry entering the discharge box 1101 finally overflows.

[0051] The slurry entering the adapter cylinder 4 then enters the conveying channel 8 and flows downward along the corrugated pipe 10 to the discharge assembly 11. At the same time, the extension and retraction of the hydraulic cylinder 9 drives the fixed plate 1104 and the discharge box 1101 to move, adjusting the overall height of the discharge assembly 11 so that it is as close to the mold as possible, reducing the height difference when the slurry falls, and avoiding slurry splashing. When the slurry reaches the discharge assembly 11, it enters the discharge pipe 1107 through the corrugated pipe 10, and then enters the discharge box 1101. As the slurry inside the discharge box 1101 gradually increases, the excess slurry will overflow from the notch 1102. The overflowing slurry falls downward into the mold for grouting. Compared with the slurry poured directly into the mold, the overflowing slurry has less kinetic energy and less impact force when poured, thus further avoiding slurry splashing when pouring into the mold.

[0052] After grouting, the inside of the discharge box 1101 needs to be cleaned, such as... Figure 5 , 6 As shown, a fixed shaft 1105 is provided on the inner wall of the discharge box 1101 via a rotating shaft, and the rear side of the fixed shaft 1105 contacts the inner wall of the discharge box 1101;

[0053] A base plate 1103 is fixedly provided on the front side of the fixed shaft 1105. A sealing strip is fixedly provided on the front end of the base plate 1103. The outer end of the base plate 1103 and the sealing strip are in contact with the inner wall of the discharge box 1101, thereby sealing the opening end of the discharge box 1101.

[0054] The bottom of the discharge box 1101 is provided with two support plates 1106 via a damping shaft. One end of the support plate 1106 extends to the bottom of the base plate 1103 and contacts the base plate 1103. The support plate 1106 plays a role in limiting and fixing the base plate 1103.

[0055] After the mold is filled, rotate the tray 1106 to remove it from the bottom of the base plate 1103. The base plate 1103 will then be free of obstruction. At this time, rotate the fixed shaft 1105 downward to rotate the base plate 1103, thereby opening the bottom of the discharge box 1101. The remaining slurry inside the discharge box 1101 can then be poured out from here, thus cleaning the remaining slurry inside the discharge box 1101.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
