Description

Technical Field

[0001] This utility model relates to the field of concrete layered pouring, and in particular to a concrete vibration layered pouring device. Background Technology

[0002] In the existing cement pipe casting process, the steel cage is first placed into the mold cavity by hand, and then the mixed concrete is poured into the mold cavity by mixing equipment. Finally, a vibrator is inserted into the concrete by hand to vibrate the concrete to remove air bubbles and prevent the cement pipe from having dents after molding.

[0003] However, when using a vibrator inserted into the concrete, it is difficult to ensure that every part of the concrete in the mold cavity vibrates evenly, which can easily cause air bubbles to be left in the concrete, resulting in depressions on the cement pipe after molding.

[0004] Therefore, in the prior art, there are casting devices that can vibrate the concrete in the mold cavity as a whole, which can prevent air bubbles from remaining in the concrete and causing the cement pipe to still have a concave area after molding. However, during the process of the casting device vibrating the concrete as a whole, the heavier aggregates (such as stones) in the concrete tend to move downwards, resulting in an increase in the proportion of aggregates in the lower layer of concrete and a decrease in the proportion of aggregates in the upper layer of concrete. Utility Model Content

[0005] In order to overcome the disadvantage that in the process of overall vibration of concrete by existing casting equipment, the heavier aggregates in the concrete tend to move downward, resulting in an increase in the proportion of aggregates in the lower layer of concrete and a decrease in the proportion of aggregates in the upper layer of concrete, this utility model provides a concrete vibration layered casting device.

[0006] The technical implementation scheme of this utility model is as follows: a concrete vibration layered pouring device, including a base plate, electric push rods, and a mold; at least two electric push rods are fixedly connected to the base plate; the telescopic parts of all electric push rods are jointly fixedly connected to the mold; the mold has a mold cavity; it also includes support rods, a support plate, a mounting plate I, a rotating ring I, a vibrating rod I, a mounting plate II, a rotating ring II, a vibrating rod II, a frustum plate, a power assembly I, and a power assembly II; several support rods are fixedly connected to the base plate, and all support rods are slidably connected to the mold; all support rods are jointly fixedly connected to the support plate, and the support plate is slidably connected to the mold cavity; a mounting plate I is inserted into the outside of the mold; the mounting plate I is rotatably connected to... A rotating ring 1 is rotatably connected to a mold; several vibrating rods 1 are fixedly connected to the rotating ring 1; a mounting plate 2 is inserted into the inner side of the mold; the rotating ring 2 is rotatably connected to the mounting plate 2, and the rotating ring 2 is rotatably connected to the mold; several vibrating rods 2 are fixedly connected to the rotating ring 2, and the vibrating rods 1 and 2 work together to remove air bubbles from the concrete; a frustum-shaped disc is fixedly connected to the mounting plate 2; a power assembly 1 for driving the rotating ring 1 and its connected parts to rotate is connected to the mounting plate 1; a power assembly 2 for driving the rotating ring 2 and its connected parts to rotate is connected to the mounting plate 2.

[0007] More preferably, the power assembly includes a gear ring, a motor, and a gear; the gear ring is fixedly connected to the rotating ring; the motor is fixedly connected to the mounting plate; the output shaft of the motor is fixedly connected to the gear, and the gear meshes with the gear ring.

[0008] More preferably, the power assembly two includes a gear ring two, a motor two, and a gear two; the rotating ring two is fixedly connected to the gear ring two; the mounting plate two is fixedly connected to the motor two; the output shaft of the motor two is fixedly connected to the gear two, and the gear two meshes with the gear ring two.

[0009] More preferably, it also includes a limiting disk; the mounting disk is fixedly connected to the limiting disk.

[0010] More preferably, the support plate is provided with several limiting parts; each limiting part is provided with two guide parts.

[0011] More preferably, all vibrators are set to an inclined position.

[0012] Beneficial effects: By first pouring concrete into a temporary storage cavity and then removing air bubbles from the concrete in the temporary storage cavity using vibrators one and two, the air-removed concrete is then transferred from the temporary storage cavity to the mold cavity. The mold cavity is then filled with air-removed concrete layer by layer from bottom to top. Since each layer of concrete poured into the mold cavity is relatively thin, the aggregate can be evenly distributed at a lower height. This helps to control the movement and settlement of coarse aggregates (such as gravel) in each layer, thereby reducing aggregate segregation. This avoids the problem that, during the overall vibration of concrete in existing casting equipment, heavier aggregates tend to move downwards, leading to an increase in the proportion of aggregate in the lower layer of concrete and a decrease in the proportion of aggregate in the upper layer of concrete.

[0013] By setting all two vibrators to an inclined state, the two vibrators can push the concrete on one side of the rotating ring in the temporary storage cavity to flow towards the rotating ring, thereby achieving dynamic material uniformity. This improves the uniformity of concrete distribution in the temporary storage cavity and increases the efficiency of air bubble removal. This avoids the problem that the two vibrators cannot effectively remove air bubbles from the concrete on the side of the temporary storage cavity near the rotating ring, and that the two vibrators do not generate excessive vibration on the side of the temporary storage cavity near the rotating ring, thus affecting the overall quality of the concrete in the temporary storage cavity.

[0021] Example

[0022] Vibratory layered concrete pouring device, such as Figures 1-5 As shown, it includes a base plate 1, electric push rods 2, and a mold 3; the base plate 1 is bolted to two electric push rods 2; the telescopic parts of all electric push rods 2 are fixed to the mold 3; the mold 3 is provided with a mold cavity 301 for casting cement pipes;

[0023] It also includes support rods 4, support plate 5, mounting plate 1 6, rotating ring 1 7, vibrating rod 1 8, mounting plate 2 9, rotating ring 2 10, vibrating rod 2 11, frustum plate 12, power assembly 1 and power assembly 2; the base plate 1 is fixedly connected to four support rods 4 arranged in a circular array, and all support rods 4 are slidably connected to the mold 3; all support rods 4 are fixedly connected to the support plate 5, and the support plate 5 is slidably connected to the mold cavity 301; the mounting plate 1 6 is inserted into the outside of the mold 3; the mounting plate 1 6 is rotatably connected to the rotating ring 1 7, and the rotating ring 1 7 is rotatably connected to the mold 3. The following components are connected: a rotating ring 7 is fixedly connected to four vibrating rods 8 arranged in a ring array; a mounting plate 9 is inserted into the inner side of the mold 3; a rotating ring 10 is rotatably connected to the mounting plate 9, and the rotating ring 10 is rotatably connected to the mold 3; four vibrating rods 11 arranged in a ring array are fixedly connected to the rotating ring 10; a frustum disc 12 for diverting concrete is fixedly connected to the mounting plate 9; a power assembly 1 is connected to the mounting plate 6, and the power assembly 1 is connected to the rotating ring 7; a power assembly 2 is connected to the mounting plate 9, and the power assembly 2 is connected to the rotating ring 10.

[0024] The power assembly includes a gear ring 111, a motor 112, and a gear 113; the rotating ring 7 is fixedly connected to the gear ring 111; the mounting plate 6 is bolted to the motor 112; the output shaft of the motor 112 is fixedly connected to the gear 113, and the gear 113 meshes with the gear ring 111.

[0025] The second power assembly includes a gear ring 121, a motor 122, and a gear 123; the rotating ring 10 is fixedly connected to the gear ring 121; the mounting plate 9 is bolted to the motor 122; the output shaft of the motor 122 is fixedly connected to the gear 123, and the gear 123 meshes with the gear ring 121.

[0026] It also includes a limiting disc 13; the mounting disc 6 is fixedly connected to the limiting disc 13 for limiting the concrete.

[0027] The support plate 5 is provided with several limiting parts 501 for restricting the steel cage; each limiting part 501 is provided with two guide parts 502 for better locking the steel cage into its interior.

[0028] All vibrating rods 211 are set to an inclined state, which allows the vibrating rods 211 to push the concrete in the temporary storage cavity 701 located on one side of the rotating ring 210 towards the direction of the rotating ring 17.

[0029] During casting, if Figure 5As shown, the reinforcing cage is first placed manually on the support plate 5, aligning the center point of the cage with the center point of the frustum 12 to prevent the vibrators 8 and 11 from colliding with it during rotation. Then, the mixed concrete is poured onto the frustum 12 using a mixing device, and the outward splashing concrete is controlled by the limiting plate 13 to prevent it from splashing outside the device until the cavity between the rotating rings 7 and 10 is filled with concrete. This cavity will be described below as a temporary storage cavity 701. Then, the vibrators 8 and 11 are started. Simultaneously, using a top-down view as a reference, the output shaft of the control motor 112 drives the vibrators sequentially through the gear 113, gear ring 111, and rotating ring 7. The first 8 rotates counterclockwise, controlling the output shaft of the second motor 122 to drive the second vibrator 11 to rotate counterclockwise through the second gear 123, the second gear ring 121, and the second rotating ring 10. This causes the first 8 and the second 11 to vibrate the concrete poured in the temporary storage cavity 701 to remove air bubbles. After the air bubbles in the concrete in the temporary storage cavity 701 are removed, the telescopic part of the electric push rod 2 is controlled to push the mold 3 and its connected parts upward to the same height as the temporary storage cavity 701. This allows the concrete with the air bubbles removed to be transferred from the temporary storage cavity 701 to the mold cavity 301. The above operation process is repeated until the mold cavity 301 is filled with concrete with the air bubbles removed layer by layer from bottom to top, thus completing the casting of the cement pipe.

[0030] When the cast cement pipe needs to be demolded, the installation plate 1 6 and its connected parts and the installation plate 2 9 and its connected parts are first removed manually from the mold 3. Then, the extension part of the electric push rod 2 is controlled to move the mold 3 downward to return to the initial position, so that the mold 3 is separated from the cement pipe. Then, the cement pipe is transferred away from the support plate 5 by an external transfer device.

[0031] This method involves first pouring concrete into a temporary storage cavity 701, then removing air bubbles from the concrete using vibrators 8 and 11. The air-removed concrete is then transferred from the temporary storage cavity 701 to the mold cavity 301, and the mold cavity 301 is filled layer by layer from bottom to top with the air-removed concrete. Because each layer of concrete in the mold cavity 301 is relatively thin, the aggregate can be evenly distributed at a lower height. This helps control the movement and settlement of coarse aggregates (such as gravel) in each layer, thereby reducing aggregate segregation. This avoids the problem in existing casting equipment where heavier aggregates tend to move downwards during overall vibration, leading to an increase in the proportion of aggregate in the lower layer and a decrease in the proportion of aggregate in the upper layer.

[0032] Furthermore, by adding a limiting part 501 and a guide part 502 on the limiting part 501, after the steel cage is placed on the support plate 5, the manual person drives the steel cage to rotate clockwise from the top down as a reference, so that the steel bars on the steel cage enter the limiting part 501 under the action of the guide part 502, so that the limiting part 501 positions and restricts the steel cage, allowing the manual person to quickly adjust the center point of the steel cage to be aligned with the center point of the rotating ring 7, and preventing the concrete poured onto the truncated disc 12 from flowing into the temporary storage cavity 701, which could easily push the steel cage to move and cause the center point of the steel cage to deviate from the center point of the truncated disc 12.

[0033] Considering that during the process of feeding the mixing equipment into the temporary storage chamber 701, the concrete slides down the outside of the frustum 12 and accumulates in the temporary storage chamber 701 near the rotating ring 10, resulting in a thicker concrete layer in this area. Conversely, the concrete on the side of the temporary storage chamber 701 near the rotating ring 7 is relatively less. As a result, the vibrator 11 has difficulty effectively removing air bubbles from the concrete on the side of the temporary storage chamber 701 near the rotating ring 10. At the same time, the vibrator 8 causes excessive vibration to the concrete on the side of the temporary storage chamber 701 near the rotating ring 7, thereby affecting the overall quality of the concrete in the temporary storage chamber 701.

[0034] Therefore, by setting all vibrating rods 2 11 to an inclined state, during the counterclockwise rotation of all vibrating rods 2 11 in the concrete in the temporary storage cavity 701, the vibrating rods 2 11 can push the concrete on the side of the rotating ring 2 10 in the temporary storage cavity 701 to flow towards the rotating ring 1 7, thereby achieving dynamic material uniformity, improving the uniformity of concrete distribution in the temporary storage cavity 701, and increasing the efficiency of air bubble removal. This avoids the problem that the vibrating rods 2 11 cannot effectively remove air bubbles in the concrete on the side of the temporary storage cavity 701 near the rotating ring 2 10, while the vibrating rod 1 8 generates excessive vibration on the side of the temporary storage cavity 701 near the rotating ring 1 7, thus affecting the overall quality of the concrete in the temporary storage cavity 701.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
