Description

Technical Field

[0001] This utility model relates to the field of building processing, and more specifically, to a vibratory compaction device for precast PC components. Background Technology

[0002] In today's rapidly developing construction industry, precast PC components have been widely used in various construction projects due to their advantages such as high efficiency, environmental friendliness, and stable quality. Demolding is a crucial step in the production process of precast PC components.

[0003] Chinese Patent Announcement No. CN213107369U discloses a vibratory compaction device for precast PC components. The device includes a casting mold, mounting plates, a vibratory compaction table, a vibratory compaction base, a rotating ring, a right support, a vibratory compaction motor, a reduction gearbox, a left support, a bearing seat, an eccentric rotating shaft, an eccentric rotating roller, a controller support column, a controller, and a bottom support plate. The front and rear parts of the top left side of the bottom support plate are respectively connected to the bottom end of a set of left supports. The front and rear parts of the top right side of the bottom support plate are respectively connected to the bottom end of a set of right supports. The top of each set of right supports is respectively connected to the bottom end of a set of reduction gearboxes. The front and rear sides of the top of the vibratory compaction table are detachably connected to the bottom end of a set of mounting plates. The inner ends of the two sets of mounting plates are respectively connected to the lower front and rear ends of the casting mold. The rear left side of the top of the bottom support plate is connected to the bottom end of the controller support column. The top of the controller support column is connected to the middle of the bottom end of the controller.

[0004] However, the fixed structure in the aforementioned patent results in a lack of height adjustment between the casting mold and the mounting base. In actual casting operations, after pouring concrete and other materials, demolding is required. However, because the casting mold cannot be raised or lowered, workers must use a traditional and cumbersome method. They may need to pry open the edges of the mold to try and separate the casting from it, then carefully remove the casting piece piece from the mold. This process often consumes a significant amount of time and manpower, reducing efficiency and potentially damaging the integrity of the casting piece due to improper handling. The long demolding time also affects the turnover efficiency of the casting mold, extending the overall production cycle and increasing production costs.

[0005] Therefore, a vibratory compaction device for precast PC components is proposed to address the above problems. Utility Model Content

[0008] 2. Technical Solution

[0029] Example:

[0030] Please see Figure 1-4 A vibratory compaction device for precast PC components includes a base 1 made of high-strength steel with multiple shock-absorbing rubber pads at its bottom to reduce vibrations to the ground during operation. A connecting frame 11 is welded to the top of the base 1; the connecting frame 11 is a rectangular frame structure made of welded square steel pipes. A top plate 12 and a fixing plate 13 are bolted to the top of the connecting frame 11. A template 16 is slidably connected between the top plate 12 and the fixing plate 13. The top plate 12 has a first limiting groove 14 and a second limiting groove 15 on its upper and lower surfaces, respectively. Both the first limiting groove 14 and the second limiting groove 15 have T-shaped cross-sections. A scraper 19 is slidably connected above the template 16.

[0031] Please see Figure 1-4 The upper and lower sides of the template 16 are respectively fixedly connected by welding to a first limiting block 17 and a second limiting block 18. The shapes of the first limiting block 17 and the second limiting block 18 are adapted to the shapes of the corresponding limiting grooves. They are both U-shaped structures and the materials are the same as those of the template 16.

[0032] Please see Figure 1-4 The first limiting block 17 and the first limiting groove 14 are slidably connected, and the second limiting block 18 and the second limiting groove 15 are slidably connected to ensure the stability and smoothness of the template 16 during the sliding process.

[0033] Please see Figure 1-4 The connecting frame 11 is rotatably connected to a bidirectional screw 21 via a bearing. Both sides of the bidirectional screw 21 are provided with limiting rods 22. Both limiting rods 22 are fixedly connected to the connecting frame 11 by welding. The limiting rods 22 are cylindrical structures.

[0034] Please see Figure 1-4 Both sides of the outer wall of the bidirectional screw 21 are threaded with moving blocks 23. Both moving blocks 23 are slidably connected to the limiting rod 22. The top of each moving block 23 is rotatably connected to a support rod 24 via a pin. The top of the support rod 24 and the bottom of the template 16 are rotatably connected via a pin.

[0035] Please see Figure 1-4 The drive motor 25 is fixedly connected to the outside of the connecting frame 11 by bolts. The drive motor 25 is a servo motor, and its output end and the end of the bidirectional screw 21 are fixedly connected by a coupling to achieve precise power transmission and control.

[0036] Please see Figure 1-4 A vibratory motor 3 is fixedly connected to the top of the top plate 12 by bolts. The output end of the vibratory motor 3 is connected to a vibratory rod 31 through an eccentric wheel drive, and its surface is provided with multiple protrusions to enhance the vibration effect.

[0037] Working principle: When manufacturing PC components, first adjust the formwork 16 to the appropriate position, and then slowly pour cement that meets the mix proportion requirements into the formwork 16. During the pouring process, it is important to control the cement flow rate and filling amount to avoid overflow or insufficient filling.

[0038] After the grouting is completed, the vibratory motor 3, which is fixedly connected to the top plate 12, is turned on. The output end of the vibratory motor 3 drives the vibratory rod 31 to start working through a specific transmission structure such as an eccentric wheel. The vibratory rod 31 acts on the cement inside the formwork 16 with high-frequency vibration. Through continuous and efficient vibration, air bubbles trapped inside the cement are gradually expelled. As the vibration proceeds, the cement particles rearrange and compact under the action of vibration, making the cement more even and dense, effectively improving the internal quality and structural strength of the PC component.

[0039] Once the cement inside the template 16 has been fully vibrated and reached a preliminary solidification state, the workers can start the drive motor 25 fixed externally to the connecting frame 11. The drive motor 25 serves as a power source, and its output end is tightly connected to the end of the bidirectional screw 21 through a coupling, ensuring that the rotational power of the motor can be stably and efficiently transmitted to the bidirectional screw 21, causing the bidirectional screw 21 to rotate.

[0040] Because the threads on both sides of the outer wall of the bidirectional screw 21 rotate in opposite directions, during its rotation, the movable blocks 23 connected by the threads on both sides will move towards each other along the axial direction of the bidirectional screw 21. At the same time, the movable blocks 23 maintain a sliding connection with the limiting rod 22, and the limiting rod 22 is firmly fixed to the connecting frame 11. This restricts the movable blocks 23 to only move linearly along the direction of the limiting rod 22, thereby ensuring the stability and accuracy of the movement of the movable blocks 23.

[0041] As the distance between the two moving blocks 23 gradually decreases, the support rod 24, which is rotatably connected to the top of the moving blocks 23, also changes angle. Because the top of the support rod 24 is rotatably connected to the bottom of the template 16 via a pin, this change in angle of the support rod 24 will push the template 16 to slide downward between the top plate 12 and the fixed plate 13. During this process, the first limiting block 17 and the second limiting block 18, which are fixedly connected to the upper and lower sides of the template 16 respectively, will slide smoothly within the first limiting groove 14 and the second limiting groove 15 respectively opened on the upper and lower surfaces of the top plate 12, further ensuring the stability and accuracy of the template 16's downward movement.

[0042] When the first limiting block 17 is fully inserted into the first limiting groove 14, the surface of the template 16 is exactly on the same horizontal line as the surface of the top plate 12. At this time, the bonding force between the PC component and the template 16 is weakened, and the demolding operation of the PC component is successfully completed. This demolding method utilizes the coordinated movement of the mechanical structure. Compared with traditional demolding methods, it is not only convenient and quick to operate, but also effectively reduces damage to the PC component, improving production efficiency and product quality.

[0043] After demolding, the demolded PC components can undergo subsequent curing and processing procedures. Simultaneously, template 16 can be cleaned and inspected to prepare for the next batch of PC component fabrication.

[0044] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
