Description

Technical Field

[0001] This invention relates to the field of surface roughness treatment technology for prefabricated building components, specifically a high-pressure water jet roughening process and equipment for the side surface of prefabricated building panels. Background Technology

[0002] Prefabricated construction refers to a construction method in which building components and accessories are prefabricated in a factory and then transported to the construction site for assembly and installation, much like building with blocks. After processing, prefabricated components typically have smooth surfaces. However, for some prefabricated components that require on-site assembly and secondary pouring, the smooth surface can lead to insufficient bonding between the old and new concrete after the secondary pour. Therefore, after the prefabricated components are formed, their surfaces need to be roughened.

[0003] In existing technologies, high-pressure water jetting is used to roughen the surface of precast components. However, the surfaces of the precast components are regular planes without any concave or convex joint areas. Due to the concave and convex joint areas, the distance between the treated surface and the nozzle of the high-pressure water jet changes, resulting in insufficient roughness treatment of the concave parts and over-treatment of the convex parts. This causes the aggregate of the precast component to loosen and also affects the bonding strength of the precast component after secondary casting. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-pressure water jet roughening process and equipment for the sides of prefabricated building panels. By utilizing the weight of the prefabricated component itself, and in conjunction with an adjustment component, the position of the prefabricated component can be adjusted, thereby ensuring that the distance between the roughened surface and the nozzle is relatively consistent, and improving the uniformity of the roughness treatment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-pressure water jet roughening treatment device for the side of prefabricated building slabs, comprising a conveyor line, a plurality of fixed seats symmetrically installed at the top end of the conveyor line, a rotating rod rotatably installed between two of the fixed seats, a conveying roller provided on the outer wall of the rotating rod, an assembled prefabricated component body placed above the conveying roller, a position calibration component symmetrically installed near an edge at the top end of the conveyor line, water jet treatment components installed on both sides of the middle part of the conveyor line, an adjustment component installed below the conveying roller in the middle part of the conveyor line, a sensing component installed on one side of the adjustment component, and a side sliding component provided at the upper end of the sensing component; The water jet treatment component includes mounting frames installed on both sides of the conveyor line. Two hydraulic rotating heads are installed inside the mounting frames, and multiple high-pressure nozzles are installed on the rotating ends of the hydraulic rotating heads. The adjustment component includes a mounting frame installed below the conveyor line. A guide seat is symmetrically fixed on one side of the mounting frame. An L-shaped guide plate is slidably installed on the inner side of the guide seat. A fitting roller is rotatably installed on the inner side of one end of the L-shaped guide plate. A first connecting swing arm is rotatably installed on the upper corner of the L-shaped guide plate. A sliding seat is rotatably installed below one end of the first connecting swing arm. A second connecting swing arm is rotatably installed on the lower end of the sliding seat. A pushing crossbar is slidably installed on the inner side of the two sliding seats. Multiple pushing brackets are installed on the top of the pushing crossbar. The sensing component includes a mounting frame installed on one side of the mounting crossbeam. Support arms are symmetrically installed on one side of the mounting frame. A sensing arm is slidably installed on the inner side of one end of the support arm. A sensing base is installed at the lower ends of the two sensing arms. Pushing slopes are provided on both sides of the sensing base. A contact part is slidably provided at the upper end of the sensing arm. The upper part of the contact part is arc-shaped, and the contact part contacts the splicing protrusion. Guide rods are symmetrically installed on one side of the sliding crossbar, a baffle is installed on one side of the outer wall of the guide rod, a spring is installed on the other side of the outer wall of the guide rod, and a blocking plate is installed on the other side of the mounting frame.

[0006] Preferably, the position calibration component includes a mounting base installed at the top of the conveyor line near one edge. An electric push rod is installed on one side of the upper end of the mounting base. A pusher plate is fixed to the telescopic end of the electric push rod for calibrating the position of the assembled prefabricated body after it is placed in, so that the position of the splicing protrusion corresponds to the position of the contact part. One side of the prefabricated assembly body has a splicing protrusion, and the other side of the prefabricated assembly body has a splicing groove that cooperates with the splicing protrusion for splicing.

[0007] Preferably, the outer walls of the three conveying rollers corresponding to the positions of the water jet treatment components are provided with annular grooves, and rotating rings are rotatably provided on both sides of the inner side of the annular grooves. A limit strip is fixed on the outer wall of the rotating rod, and the inner wall of the conveying rollers is provided with parallel grooves that cooperate with the limit strips to limit the position of the conveying rollers during the sliding process. The rotating rings are rotatable so that the normal rotation of the conveying rollers is not affected during the parallel pushing of the conveying rollers.

[0008] Preferably, the fitting roller corresponds to the position of the pushing inclined plane, and is used to convert the gravity of the prefabricated body into a pushing force for adjusting the position of the prefabricated body.

[0009] Preferably, one end of the second connecting swing arm is rotatably connected to the mounting crossbeam, the upper end of the pushing bracket is a semi-circular ring structure corresponding to the annular groove, which is used to push the conveying roller, the guide rod is slidably connected to the blocking frame plate, and the spring is located between the baffle and the blocking frame plate.

A vertical groove is provided on one edge of the upper end of the sensing arm to cooperate with the rolling rod. The vertical groove is vertically arranged. By setting the side-sliding component, during the process of adjusting the position of the prefabricated body, the splicing protrusion will not slide laterally with the contact part, which would reduce the supporting contact area of ​​the splicing protrusion and affect the stability of pressure transmission during the pushing process of the prefabricated body.

[0012] Compared with existing technologies, this invention provides a high-pressure water jet roughening process and equipment for the sides of prefabricated building panels, which has the following beneficial effects: The initial positioning adjustment of the prefabricated component is completed by the calibration component, allowing the splicing protrusions to accurately align with the sensing component. Utilizing the weight of the prefabricated component itself, the positioning component is used to adjust its position, ensuring that the distance between the roughened surface and the nozzle is relatively consistent, improving the uniformity of the roughness treatment. Furthermore, it avoids over-processing at the splicing protrusions, preventing loosening of the aggregate in the prefabricated component and affecting the bonding strength after secondary casting. The side-sliding component prevents lateral sliding between the splicing protrusions and the contact area during the adjustment of the prefabricated component's position, thus reducing the supporting contact area and affecting the stability of pressure transmission during the pushing process of the prefabricated component.

A sensing base 54 is installed at the lower end of the two sensing arms 53. Pushing inclined surfaces 55 are opened on both sides of the sensing base 54. A contact part 56 is slidably provided at the upper end of the sensing arm 53. The upper part of the contact part 56 is arc-shaped. The contact part 56 contacts the splicing protrusion 71. A guide rod 481 is symmetrically installed on one side of the push crossbar 48. A baffle 482 is installed on one side of the outer wall of the guide rod 481. A spring 483 is installed on the other side of the outer wall of the guide rod 481. A blocking plate 484 is installed on the other side of the mounting frame 41. The position calibration component 2 includes a mounting base 21 installed at the top of the conveyor line 1 near one edge. An electric push rod 22 is installed on one side of the upper end of the mounting base 21. A pusher plate 23 is fixed to the telescopic end of the electric push rod 22. It is used to calibrate the position of the prefabricated body 7 after it is placed in the assembly, so that the position of the splicing protrusion 71 corresponds to the position of the contact part 56. One side of the prefabricated body 7 has a splicing protrusion 71, and the other side of the prefabricated body 7 has a splicing groove 72 that cooperates with the splicing protrusion 71 for splicing.

[0017] In embodiment two, three conveying rollers 12 have annular grooves 122 on their outer walls corresponding to the positions of the water jet treatment component 3. Rotating rings 123 are rotatably mounted on both sides of the annular grooves 122. A limiting strip 124 is fixed to the outer wall of the rotating rod 121. The limiting strip 124 restricts rotation between the conveying rollers 12 and the rotating rod 121, preventing interference with the normal conveying of the prefabricated body 7. Parallel grooves that cooperate with the limiting strips 124 are provided on the inner walls of the conveying rollers 12 to limit their position during sliding. The rotatable rotating rings 123 allow for... During the parallel pushing of the conveyor roller 12, the normal rotation of the conveyor roller 12 is not affected. The position of the contact roller 44 corresponds to that of the pushing inclined surface 55, which is used to convert the gravity of the assembly prefabricated body 7 into a pushing force for adjusting the position of the assembly prefabricated body 7. One end of the second connecting swing arm 47 is rotatably connected to the mounting crossbeam 41. The upper end of the pushing bracket 49 is a semi-circular ring structure corresponding to the annular groove 122, which is used to push the conveyor roller 12. The guide rod 481 is slidably connected to the blocking frame plate 484. The spring 483 is located between the baffle plate 482 and the blocking frame plate 484.

[0018] In embodiment three, a rectangular base 57 is connected to the lower part of the contact portion 56. A transverse groove is provided at the upper end of the sensing arm 53 corresponding to the rectangular base 57. The rectangular base 57 and the sensing arm 53 are slidably connected. The side-sliding component includes an arc-shaped groove 63 on one side of the rectangular base 57. A rolling rod 61 is movably installed on the inner side of the arc-shaped groove 63. A counterweight seat 62 is rotatably installed at both ends of the rolling rod 61. A vertical groove 6 is provided at one edge of the upper end of the sensing arm 53 to cooperate with the rolling rod 61. The vertical groove 6 is vertically set. With the setting of the side-sliding component, during the process of adjusting the position of the prefabricated body 7, the splicing protrusion 71 will not slide laterally with the contact portion 56, which will reduce the supporting contact area of ​​the splicing protrusion 71 and affect the stability of pressure transmission during the process of pushing the prefabricated body 7.

[0019] Example 4: A processing method for a high-pressure water jet roughening device on the side of prefabricated building slabs, characterized by the following processing steps: Step 1: The prefabricated body 7 is placed into the conveyor line 1 from one side using a mechanical gripping device. The prefabricated body 7 is conveyed by the conveying rollers 12 at a speed of 5-10 m / min. It should be noted that the gripping device is a commonly used device in the prefabrication process and will not be described in detail in this application. Step 2: When the prefabricated body 7 is transported to the position calibration component 2, the extension state of the electric push rods 22 on both sides is controlled to drive the pusher plate 23 to push the prefabricated body 7, thereby completing the position calibration of the prefabricated body 7 and making the position of the splicing protrusion 71 correspond to the contact part 56. It should be noted that this application uses an external control terminal for control, which is a commonly used control method in the field and will not be described in detail in this application. Step 3: When the water jet is transported to the water jet treatment component 3, the rotation speed of the rotating end in the first stage of water jet treatment is 400-500 rpm, the water jet pressure of the high-pressure nozzle 33 is 70-80 MPa, and the roughness after treatment is 1-3 mm. In the second stage of water jet treatment, the rotation speed of the rotating end is 300-400 rpm, the water jet pressure of the high-pressure nozzle 33 is 120-160 MPa, and the roughness after treatment is 3-5 mm. Step 4: After the splicing protrusion 71 enters the second stage of water jet treatment, when the splicing protrusion 71 moves to one of the contact portions 56, as the assembly prefabricated body 7 continues to move, the splicing protrusion 71 will generate a downward pressure on the contact portion 56, further pushing the sensing arm 53 and sensing seat 54 downward. Due to the downward movement of the sensing seat 54, the contact roller 44 rolls upward along the pushing slope 55, which will push the L-shaped guide plate 43 to slide inside the guide seat 42. As the guide seat 42 slides, it will drive the first connecting swing arm 45 to rotate. With the help of the first connecting swing arm 45, the second connecting swing arm 47, and... With the cooperation of the guide rod 481, the sliding seat 46 slides along the push bar 48 while pushing the push bar 48 horizontally to one side. At this time, the spring 483 is also compressed. During the pushing process of the push bar 48, the push bracket 49 will generate a thrust on one side of the annular groove 122 at the conveying roller 12, thereby pushing the conveying roller 12 as a whole to move horizontally to one side along the rotating rod 121. This completes the automatic adjustment of the position distance between the splicing protrusion 71 and the splicing groove 72 and the high-pressure nozzle 33 at the second stage water jet, thereby ensuring that the distance between the concave and convex treatment surface and the nozzle is relatively consistent and improving the uniformity of the roughness treatment. Step 5: During the process of pushing the prefabricated body 7, the prefabricated body 7 moves laterally, which will cause the contact part 56 and the rectangular base 57 to slide to the same side. The arc groove 63 at the rectangular base 57 will push the rolling rod 61 to slide upward along the arc groove 63. When the rolling rod 61 slides upward, its position in the vertical groove 6 will also rise, thereby achieving the purpose of sliding to one side with the prefabricated body 7 and avoiding the situation where the prefabricated body 7 slips off from the contact part 56. Step 6: After the splicing protrusion 71 separates from the other contact part 56, the spring force of the spring 483 drives the adjustment component 4 and the sensing component 5 to reset as a whole. The contact part 56 and the rectangular base 57 will also reset under the gravity of the rolling rod 61 and the counterweight 62, which facilitates the subsequent processing of the assembly prefabricated body 7. Step 7: The processed prefabricated assembly body 7 is transported to the other side and then picked up and stacked by mechanical gripping equipment.

Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.

Step 2: When the prefabricated body is transported to the position calibration component, the extension state of the electric push rods on both sides is controlled to drive the pusher plate to push the prefabricated body, thereby calibrating the position of the prefabricated body and making the position of the splicing protrusion correspond to the contact part.

Step 6: After the splicing protrusion separates from the other contact part, the spring force will drive the adjustment component and the sensing component to reset as a whole. The contact part and the rectangular base will also reset under the gravity of the rolling rod and the counterweight, which will facilitate the subsequent processing of the assembly prefabricated body. Step 7: The processed prefabricated assembly body is transported to the other side and then picked up and stacked by mechanical gripping equipment.
