Abstract
Description
Technical Field
[0001] This utility model relates to the field of molded building materials technology, specifically to a concrete vibration compaction device for cement pole production. Background Technology
[0002] In the production process of cement poles, in order to ensure the compactness of concrete, it is usually necessary to use a vibratory compaction device to vibrate the concrete; by eliminating air bubbles inside the concrete and enhancing the bonding between aggregate and cement paste, the strength and durability of the cement poles are improved.
[0003] Currently, commonly used concrete vibration compaction equipment in the industry mainly includes attached vibrators, immersion vibrators, and vibration platforms. These devices generate vibration by driving eccentric components with motors to achieve concrete compaction. However, most devices can only provide vibration in a single direction. For example, attached vibrators mainly generate horizontal vibration, while immersion vibrators focus on vertical vibration. This single vibration mode makes it difficult to make the concrete uniformly compacted in the mold tube. Especially in the slender structure of the cement rod, it is easy to cause defects such as residual air bubbles and honeycomb surface in the bottom or corner areas. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes a concrete vibration compaction device for cement pole production, comprising a vibration table with multiple mold tubes mounted on its top; a mounting base below the vibration table, with a first servo motor mounted on its top; the output end of the first servo motor connected to a vertically extending shaft passing through the vibration table; a first eccentric cam fixed to the outer side of the shaft at its upper end on the vibration table; the first eccentric cam contacting the mold tubes during rotation; a connecting plate fixed to the top of the vibration table on the side of each mold tube; a planar strip on the outer wall of each mold tube; a sliding rod fixed to the outer wall of the planar strip; the sliding rod passing through and slidably connected to the adjacent connecting plate; a compression spring fixed between the adjacent planar strip and the connecting plate; and a longitudinal vibration structure driving the vibration table to vibrate up and down below the vibration table.
[0005] Furthermore, the longitudinal vibration structure includes a drive shaft that is laterally positioned between the mounting base and the vibration table. One end of the drive shaft is connected to a second servo motor, and the outer sides of both ends of the drive shaft are fixed with second eccentric cams. The second eccentric cams can contact the vibration table during rotation. The four corners of the mounting table are fixed with uprights that pass through the vibration table and are slidably connected to it. A tension spring is fixed between the vibration table and the mounting base, and the tension spring is sleeved on the outside of the upright.
[0006] Furthermore, two drive shafts are provided at the front and rear ends below the vibration table. Multiple connecting plates that are rotatably connected to the drive shafts are fixed on the mounting base. Sprockets are fixed on the outer sides of both drive shafts, and the two drive shafts are connected by chains installed on the sprockets.
[0007] Furthermore, a support rod is fixed to the top of the mounting base, the support rod passes through the vibration table and is slidably connected to the vibration table, and a support block is fixed to the outer side of the support rod below the vibration table.
[0008] Furthermore, the top of the vibration table is provided with a positioning groove for the mold tube to slide.
[0009] The beneficial effects of this utility model are as follows:
[0010] A combined horizontal and longitudinal vibration mode was adopted. The first eccentric cam vibrates the mold tube, while the second eccentric cam vibrates the vibrating table vertically, creating a multi-directional vibration effect. The mold tube vibrates horizontally under the action of the first eccentric cam, effectively eliminating air bubbles in the concrete and ensuring its horizontal density. The vibrating table, driven by the second eccentric cam, vibrates longitudinally, transmitting the vibration to the vertical direction of the concrete, ensuring sufficient vertical compaction as well.

[0016] The present invention will be further described below with reference to the accompanying drawings:
[0017] A concrete vibration compaction device for cement pole production, such as Figure 1 and Figure 2 As shown, the system includes a vibration table 2, with multiple mold tubes 3 mounted on its top. A mounting base 1 is located below the vibration table 2, and a support rod 18 is fixed to the top of the mounting base 1. The support rod 18 passes through the vibration table 2 and is slidably connected to it. A support block 19 is fixed to the outer side of the support rod 18 below the vibration table 2. A first servo motor 4 is mounted on the top of the mounting base 1. The output end of the first servo motor 4 is connected to a rotating shaft 5 that passes vertically through the vibration table 2. A first eccentric cam 6 is fixed to the outer side of the rotating shaft 5 at the top of the vibration table 2. The first eccentric cam 6 can contact the mold tubes 3 during rotation. A connecting plate 7 is fixed to the top of the vibration table 2 on the side of the mold tubes 3. A planar strip 9 is located on the outer wall of the mold tubes 3. A sliding rod 8 is fixed to the outer wall of the planar strip 9. The sliding rod 8 passes through the adjacent connecting plate 7 and is slidably connected to it. A compression spring 10 is fixed between the adjacent planar strip 9 and the connecting plate 7. The compression spring 10 is sleeved on the outside of the sliding rod 8. A positioning groove 201 for sliding the mold tubes 3 is opened on the top of the vibration table 2.
[0018] The bottom of the mold tube 3 is embedded in the positioning groove 201 of the vibration table 2, which restricts its horizontal movement freedom. The first servo motor 4 drives the rotating shaft 5 and the first eccentric cam 6 to rotate. The first eccentric cam 6 periodically squeezes the mold tube 3, causing it to slide along the slide bar 8 in the horizontal direction. The compression spring 10 is compressed and stores energy. After the first eccentric cam 6 rotates away, the spring releases energy to reset the mold tube 3, forming a horizontal reciprocating vibration.
[0019] like Figure 1 and Figure 2 As shown, in this embodiment, a longitudinal vibration structure for driving the vibration table 2 to vibrate up and down is also provided below the vibration table 2. The longitudinal vibration structure includes a drive shaft 11 arranged laterally between the mounting base 1 and the vibration table 2. One end of the drive shaft 11 is connected to a second servo motor 12. The outer sides of both ends of the drive shaft 11 are fixed with second eccentric cams 13. The second eccentric cams 13 can contact the vibration table 2 during rotation. The four corners of the mounting base are fixed with uprights 14. The uprights 14 pass through the vibration table 2 and are slidably connected to the vibration table 2. A tension spring 15 is fixed between the vibration table 2 and the mounting base 1. The tension spring 15 is sleeved on the outside of the uprights 14. Two drive shafts 11 are provided at the front and rear ends below the vibration table 2. Multiple connecting plates 16 that are rotatably connected to the drive shafts 11 are fixed on the mounting base 1. The outer sides of both drive shafts 11 are fixed with sprockets. The two drive shafts 11 are connected by chains 17 installed on the sprockets.
[0020] The second servo motor 12 drives the drive shaft 11 to rotate, and the second eccentric cams 13 at both ends of the drive shaft 11 rotate accordingly. The long shaft portion of the second eccentric cam 13 pushes the vibration table 2 upward, and the tension spring 15 is stretched and stores energy. When the long shaft portion of the second eccentric cam 13 rotates away from the vibration table 2, the tension spring 15 releases energy and pulls the vibration table 2 downward to reset, realizing the reciprocating up-and-down vibration of the vibration table 2. The two drive shafts 11 are connected by a sprocket and a chain 17 to ensure synchronous rotation and uniform force on the vibration table 2.
[0021] The working principle of this utility model is as follows:
[0022] After the first servo motor 4 starts, its output drives the rotating shaft 5 to rotate, and the first eccentric cam 6 fixed on the rotating shaft 5 then performs circular motion. Because the center of gravity of the first eccentric cam 6 is off-center from the rotation center, its long axis portion periodically contacts the mold tube 3 and applies a lateral thrust during rotation. When the long axis portion of the first eccentric cam 6 pushes the mold tube 3, the mold tube 3 slides horizontally along the slide bar 8. At this time, the compression spring 10 fixed between the plane strip 9 of the mold tube 3 and the connecting plate 7 is compressed. When the long axis portion of the first eccentric cam 6 rotates away from the mold tube 3, the elastic force of the compression spring 10 resets the mold tube 3, thus achieving reciprocating vibration of the mold tube 3 in the horizontal direction. This horizontal vibration effectively eliminates air bubbles in the concrete in the lateral direction of the mold tube 3, making the concrete distribution more uniform in the horizontal direction.
[0023] Simultaneously, the second servo motor 12 starts, driving the drive shaft 11 to rotate, and the second eccentric cams 13 at both ends of the drive shaft 11 also rotate accordingly. Due to the eccentric structure of the second eccentric cam 13, its long shaft portion will push the vibration table 2 upward during rotation. When the long shaft portion of the second eccentric cam 13 contacts the vibration table 2 and pushes the vibration table 2 upward, the tension springs 15 sleeved on the four corner uprights 14 of the mounting base 1 are stretched; when the long shaft portion of the second eccentric cam 13 rotates away from the vibration table 2, the self-weight of the vibration table 2 and the elastic force of the tension springs 15 pull the vibration table 2 downward to reset, thereby realizing the up-and-down reciprocating vibration of the vibration table 2. The longitudinal vibration of the vibration table 2 can transmit the vibration to the concrete in the mold tube 3, so that the concrete is fully compacted in the vertical direction, further eliminating air bubbles and voids inside the concrete; the two drive shafts 11 are connected by a chain 17, so that the second eccentric cams 13 at both ends can rotate synchronously, so that the vibration table 2 is subjected to uniform force during longitudinal vibration, avoiding tilting or swaying.
[0024] The vibration of the mold tube 3 is achieved by the first eccentric cam 6, while the up-and-down vibration of the vibrating table 2 is achieved by the second eccentric cam 13. These two vibration methods work together to create a multi-directional vibration effect. The vibration of the mold tube 3 can directly act on the concrete inside the concrete mold, promoting the discharge of air bubbles and the rearrangement of particles; while the up-and-down vibration of the vibrating table 2 can produce a macroscopic vibration effect on the entire concrete mold, further improving the compactness of the concrete.
[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
