Description

Technical Field

[0001] This invention relates to the technical field of equipment for producing precast concrete components, and in particular to a vibratory compaction device for processing precast concrete components. Background Technology

[0002] In the production of precast concrete components, vibration is a crucial process to ensure concrete density and structural quality. Vibration removes air bubbles from the concrete, rearranges concrete particles, and improves the strength and durability of the precast components. As the complexity requirements of precast structures in construction projects continue to increase, many precast components are no longer simple cylindrical or slab structures, but rather have complex geometries.

[0003] Cylindrical precast concrete components are widely used in municipal engineering, water conservancy engineering, and building construction, such as drainage pipes, inspection wells, and culverts. To meet the needs of engineering connections and installation, these precast components typically have lugs, flanges, or other horizontal extensions on the cylindrical body. In the casting mold, these precast components exhibit a complex cavity structure combining vertical and horizontal sections, with the vertical sections corresponding to the main cylindrical body and the horizontal sections corresponding to the lugs and other horizontal extensions.

[0004] Traditional compaction equipment primarily uses immersion vibrators for compaction. The vibrator is typically inserted vertically into the mold, using high-frequency vibration to compact the concrete. This method is effective for simple vertical cavities, as the vibrator can reach all parts of the cavity, achieving thorough compaction.

[0005] However, traditional vibration methods have significant shortcomings for precast components with complex shapes and horizontal sections. The vibrator can only be inserted vertically and cannot penetrate the interior of horizontally extending sections such as the ear plates, resulting in insufficient vibration of the concrete in these horizontal sections. Because these horizontal sections are far from the vibrator, the transmission of vibration energy is severely attenuated, making it easy for air bubbles to remain inside the concrete, leading to quality defects such as honeycomb and pitting. The vibration effect is particularly limited at the far ends of horizontal sections, such as the ear plates, seriously affecting the overall quality and structural strength of the precast component. Summary of the Invention

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a vibration device for processing precast concrete components, which solves the technical problem that traditional vibration devices cannot directly and effectively vibrate horizontal sections, and achieves simultaneous and sufficient vibration of vertical and horizontal sections of complex-shaped precast components.

[0007] (II) Technical Solution To achieve the above objectives, this application provides a vibration device for processing precast concrete components, comprising: a platform for supporting a casting mold, the casting mold including a vertical section and a horizontal section connected to the vertical section; and a vibration mechanism including a vibration unit, a first vibrating rod connected to the output end of the vibration unit, and a second vibrating rod connected to the first vibrating rod, the first vibrating rod being arranged vertically for extending along the vertical section, and the second vibrating rod being arranged horizontally for extending from the vertical section to the horizontal section.

[0008] In one possible implementation, the vibration mechanism further includes: a lifting support; and a rotating component disposed at the top lifting end of the lifting support, the output end of which is connected to the vibration unit to drive the vibration unit to rotate, so that the second vibrating rod rotates in or out of the horizontal section.

[0009] In one possible implementation, a rotating mechanism is also included, comprising: a gear ring rotatably disposed at the bottom of the platform; a drive motor disposed at the bottom of the platform, the output end of the drive motor being provided with a gear that meshes with the gear ring; wherein the bottom of the lifting bracket is connected to the gear ring.

[0010] In one possible implementation, the lifting support includes: a fixed frame, the bottom of which is fixedly connected to a toothed ring, and the top of which is provided with an adjusting groove extending radially along the toothed ring; a sliding block, which is slidably disposed within the adjusting groove, and fasteners for fixing the fixed frame and the sliding block are provided on the sliding block; and a linear drive module, the bottom of which is connected to the sliding block; wherein the adjusting groove is used to accommodate precast cylindrical components of different diameters, and the distance between the vibrating mechanism and the central axis of the cylinder is adjusted by the radial movement of the sliding block within the adjusting groove.

[0011] In one possible implementation, the mounting frame is equipped with support wheels that abut against the top of the platform.

[0012] In one possible implementation, a support mechanism is also included, comprising: a base; a support column, the bottom of which is fixedly connected to the base and the top of which is ball-jointed to the platform, the ball-joint connection allowing the platform to tilt relative to the support column; and multiple support legs connected to the bottom of a toothed ring, the bottom of which is provided with rollers that abut against the top of the base; wherein, when the horizontal section is vibrated, the platform tilts so that the horizontal section is in a relatively low position to facilitate the discharge of air bubbles within the horizontal section.

[0013] In one possible implementation, multiple support legs are evenly distributed along the circumference of the toothed ring.

[0014] In one possible implementation, the multiple support legs include: a first telescopic support leg, adjacent to the lifting bracket, which can extend and retract along the axial direction of the toothed ring; a second telescopic support leg, which is disposed opposite to the first telescopic support leg and can extend and retract along the axial direction of the toothed ring; and two fixed support legs, which are disposed opposite to the first telescopic support leg and the second telescopic support leg; wherein the tilt angle and tilt direction of the platform are controlled by the differential extension and retraction of the first telescopic support leg and the second telescopic support leg.

[0015] In one possible implementation, the first and second telescopic outriggers are hydraulically driven.

[0016] In one possible implementation, the top of the platform is provided with a positioning groove for positioning the casting mold, and the positioning groove is coaxially arranged with the toothed ring.

[0017] (III) Beneficial Effects Compared with existing technologies, this invention provides a vibration compaction device for precast concrete component processing, which has the following beneficial effects: This vibration compaction device for precast concrete component processing, by setting up a vibration mechanism consisting of a vibration unit, a first vibrating rod, and a second vibrating rod, effectively solves the technical problem of insufficient vibration of precast components with complex shapes having vertical and horizontal sections. The high-frequency vibration energy generated by the vibration unit is transmitted to the vertical section concrete through the first vibrating rod, and simultaneously directly transmitted to the horizontal section concrete through the second vibrating rod connected to the first vibrating rod. The first vibrating rod is set vertically and extends along the vertical section, ensuring that the vertical section concrete is fully vibrated; the second vibrating rod is set horizontally and extends from the vertical section to the horizontal section, directly transmitting vibration energy to the interior of the horizontally extended parts such as the ear plate. This L-shaped or T-shaped vibrating rod combination structure allows for simultaneous vibration of the vertical and horizontal sections with a single insertion, avoiding the problem of traditional single vertical vibrating rods relying on indirect transmission of vibration energy to affect the horizontal section. Because the second vibrator can penetrate deep into the cavity of the horizontal section, the vibration point is very close to the concrete, the vibration transmission path is short, and the energy loss is small, allowing the concrete in the horizontal section to achieve vibration intensity comparable to that in the vertical section. For the ear plates on cylindrical precast components, the second vibrator can extend to the far end of the ear plate, ensuring that the concrete within the entire ear plate area is effectively vibrated, thoroughly eliminating air bubbles and achieving compaction. Compared to the problem in the prior art where the vibrator cannot enter the horizontal section, resulting in limited vibration effect, this invention achieves direct and effective vibration of the horizontal section, eliminating the problems of insufficient concrete density and easy formation of honeycomb and pitted surfaces in the horizontal section, and significantly improving the overall quality and structural reliability of complex-shaped precast components.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 4 This application provides a vibration device for processing precast concrete components, including: a platform 1 for supporting a casting mold a, the casting mold a including a vertical section a1 and a horizontal section a2 connected to the vertical section a1; and a vibration mechanism 2 including a vibration unit 21, a first vibrating rod 22 connected to the output end of the vibration unit 21, and a second vibrating rod 23 connected to the first vibrating rod 22. The first vibrating rod 22 is arranged vertically and is used to extend along the vertical section a1, and the second vibrating rod 23 is arranged horizontally and is used to extend from the vertical section a1 to the horizontal section a2.

[0022] In this invention, a vibration mechanism 2, consisting of a vibration unit 21, a first vibrating rod 22, and a second vibrating rod 23, effectively solves the technical problem of insufficient vibration of precast components with complex shapes, including a vertical section a1 and a horizontal section a2. The high-frequency vibration energy generated by the vibration unit 21 is transmitted to the concrete in the vertical section a1 through the first vibrating rod 22, and simultaneously directly to the concrete in the horizontal section a2 through the second vibrating rod 23 connected to the first vibrating rod 22. The first vibrating rod 22 is positioned vertically and extends along the vertical section a1, ensuring sufficient vibration of the concrete in the vertical section a1. The second vibrating rod 23 is positioned horizontally and extends from the vertical section a1 to the horizontal section a2, directly transmitting vibration energy to the interior of horizontally extended parts such as the ear plate. This L-shaped or T-shaped vibrating rod combination structure allows for simultaneous vibration of the vertical section a1 and the horizontal section a2 with a single insertion, avoiding the problem of traditional single vertical vibrating rods requiring indirect transmission of vibration energy to affect the horizontal section a2. Because the second vibrator 23 can penetrate deep into the cavity of the horizontal section a2, the vibration point is very close to the concrete, the vibration transmission path is short, and the energy loss is small. The concrete in the horizontal section a2 can achieve a vibration intensity comparable to that in the vertical section a1. For the ear plates on the cylindrical precast components, the second vibrator 23 can extend to the far end of the ear plate, ensuring that the concrete within the entire ear plate area is effectively vibrated, thoroughly eliminating air bubbles and achieving compaction. Compared to the problem in the prior art where the vibrator cannot enter the horizontal section a2, resulting in limited vibration effect, this invention achieves direct and effective vibration of the horizontal section a2, eliminating the problems of insufficient concrete density and easy formation of honeycomb and pitted surfaces in the horizontal section a2, significantly improving the overall quality and structural reliability of complex-shaped precast components.

[0023] Specifically, the first vibrator 22 extends vertically into the vertical section a1 of the casting mold a, compacting the concrete in the main cylindrical part. When the first vibrator 22 reaches the bottom of the vertical section a1 and is close to connecting with the horizontal section a2, the second vibrator 23 connected to it is located at the entrance of the horizontal section a2, allowing it to extend horizontally into the interior of the horizontal section a2. The vibration of the vibration unit 21, through the first and second vibrators 22 and 23, acts simultaneously on the concrete in both the vertical section a1 and the horizontal section a2, causing the concrete particles to rearrange, expelling internal air bubbles, and increasing density.

[0024] In one specific embodiment, for a cylindrical precast concrete component with ear plates, the vertical section a1 corresponds to the main cylindrical body, and the horizontal section a2 corresponds to the ear plate portion. A first vibrator 22 is inserted from the top of the cylinder and vibrates the concrete near the inner wall of the cylinder along the depth direction. A second vibrator 23 extends into the ear plate mold to vibrate the concrete in the ear plate portion. As a key connecting part of the precast component, the density of the concrete in the ear plate directly affects the overall structural strength. The horizontal vibration of the second vibrator 23 ensures the quality of the concrete in the ear plate portion.

[0025] In related technologies, vibratory rods can typically only be inserted vertically into the mold for compaction. For complex molds with horizontal extensions, the vibratory rod cannot enter the horizontal section a2, resulting in insufficient compaction of the concrete in that section and easily causing quality defects such as honeycomb and air bubbles. However, in this embodiment of the invention, through the L-shaped connection configuration of the first vibratory rod 22 and the second vibratory rod 23, the vibratory rod can extend from the vertical section a1 to the horizontal section a2, achieving omnidirectional compaction of complex-shaped molds. This solves the technical problem of insufficient compaction of concrete in the horizontal section a2 and improves the overall quality of the precast components.

[0026] In some embodiments, the vibration mechanism 2 further includes: a lifting bracket 23; a rotating component 24 disposed at the top lifting end of the lifting bracket 23, the output end of the rotating component 24 being connected to the vibration unit 21, for driving the vibration unit 21 to rotate, so that the second vibrating rod 23 rotates in or out of the horizontal section a2.

[0027] In this invention, the vibration mechanism 2 further includes a lifting support 23 and a rotating component 24. The lifting support 23 provides vertical position adjustment for the vibration mechanism 2. The rotating component 24 is located at the top lifting end of the lifting support 23 and connected to the vibration unit 21. By driving the vibration unit 21 to rotate, the second vibrating rod 23 rotates in or out of the horizontal section a2. The lifting movement of the lifting support 23, combined with the rotational movement of the rotating component 24, achieves precise positioning and motion control of the vibration mechanism 2 in three-dimensional space, improving the flexibility and accuracy of the vibration operation.

[0028] Specifically, the lifting support 23 controls the vertical position of the vibrating mechanism 2 through a lifting drive mechanism, enabling the first vibrating rod 22 to reach different depths within the vertical section a1. The rotating assembly 24 includes a rotating drive device. When vibration is required on the horizontal section a2, the rotating assembly 24 drives the vibration unit 21 to rotate together with the first vibrating rod 22 and the second vibrating rod 23. The second vibrating rod 23 spirals into the horizontal section a2. After vibration is completed, the rotating assembly 24 rotates in the opposite direction, and the second vibrating rod 23 spirals out of the horizontal section a2, facilitating the removal of the vibrating mechanism 2.

[0029] In one specific embodiment, for a casting mold a with a thin ear plate and a narrow opening, directly pushing the second vibrating rod 23 in may encounter significant resistance or jamming. Driven by the rotation of the rotating assembly 24, the second vibrating rod 23 enters the ear plate cavity in a helical trajectory. This rotational motion reduces frictional resistance with the mold wall, making it easier for the vibrating rod to enter the confined space. Simultaneously, the helical trajectory increases the vibration coverage, resulting in a more uniform vibration effect within the horizontal section a2.

[0030] In this embodiment of the invention, the rotating component 24 enables the second vibrator 23 to enter and exit the horizontal section a2 in a rotating manner, avoiding the resistance problem that may be encountered when pushing in a straight line. At the same time, the spiral motion trajectory expands the vibration coverage area and improves the uniformity and sufficiency of vibration of the concrete in the horizontal section a2.

[0031] In some embodiments, a rotating mechanism 3 is further included, comprising: a gear ring 31 rotatably disposed at the bottom of the platform 1; a drive motor 32 disposed at the bottom of the platform 1, wherein the output end of the drive motor 32 is provided with a gear 33, which meshes with the gear ring 31; wherein the bottom of the lifting bracket 23 is connected to the gear ring 31.

[0032] In this invention, the rotating mechanism 3 includes a gear ring 31 and a drive motor 32. The gear ring 31 is rotatably mounted on the bottom of the platform 1. A gear 33 is provided at the output end of the drive motor 32 and meshes with the gear ring 31. The bottom of the lifting bracket 23 is connected to the gear ring 31. The drive motor 32 drives the gear 33 to rotate, and the meshing transmission between the gear 33 and the gear ring 31 causes the gear ring 31 to rotate around the central axis of the platform 1, thereby driving the lifting bracket 23 connected to the gear ring 31 and the entire vibration mechanism 2 to perform angular positioning. The gear 33 and gear ring 31 transmission method provides precise angle control and sufficient transmission torque, which can withstand various loads generated during vibration.

[0033] Specifically, the gear ring 31 adopts an internal or external gear structure, forming a meshing transmission pair with the gear 33 on the output shaft of the drive motor 32. The drive motor 32 is started, stopped, and its speed is controlled by the control system to achieve precise angular positioning of the gear ring 31. The lifting bracket 23 is fixedly connected to the gear ring 31, and the rotation of the gear ring 31 directly drives the lifting bracket 23 and its vibrating mechanism 2 to perform circular motion around the center of the platform 1. The platform 1 supports the casting mold a, and the rotation of the gear ring 31 allows the vibrating mechanism 2 to adjust its angle relative to the mold.

[0034] In one specific embodiment, for a cylindrical precast component with multiple ear plates, each ear plate is distributed circumferentially along the cylinder. Through angle control of the rotating mechanism 3, the vibrating mechanism 2 can sequentially align with each ear plate position for vibration operation. For example, for a precast component with four evenly distributed ear plates, the rotating mechanism 3 rotates 90 degrees each time, allowing the vibrating mechanism 2 to align with the next ear plate position without requiring manual movement of equipment or re-clamping of the mold, significantly improving the processing efficiency of multi-ear plate precast components. The rotating mechanism 3 achieves automated angle positioning of the vibrating mechanism 2, enabling precise alignment with each protruding part of the precast component, avoiding the tedious manual adjustment, improving vibration efficiency and quality consistency, and is particularly suitable for complex precast components with multiple ear plates or other horizontally extending parts.

[0035] In some embodiments, the lifting support 23 includes: a fixed frame 231, the bottom of which is fixedly connected to the toothed ring 31, and the top of the fixed frame 231 is provided with an adjustment groove 2311 extending radially along the toothed ring 31; a sliding block 232, which is slidably disposed in the adjustment groove 2311, and fasteners 233 for fixing the fixed frame 231 and the sliding block 232 are provided on the sliding block 232; and a linear drive module 234, the bottom of which is connected to the sliding block 232; wherein, the adjustment groove 2311 is used to accommodate precast cylindrical components of different diameters, and the distance between the vibrating mechanism 2 and the central axis of the cylinder is adjusted by the radial movement of the sliding block 232 within the adjustment groove 2311.

[0036] In this invention, the lifting support 23 includes a fixed frame 231, a sliding block 232, and a linear drive module 234. The adjustment groove 2311 at the top of the fixed frame 231 extends radially along the toothed ring 31. The sliding block 232 is slidably disposed within the adjustment groove 2311 and fixed by fasteners 233. The bottom of the linear drive module 234 is connected to the sliding block 232. The radial movement of the sliding block 232 within the adjustment groove 2311 adjusts the distance between the vibrating mechanism 2 and the central axis of the cylinder, adapting to the vibration requirements of precast cylindrical components of different diameters. The radial adjustment mechanism enables precise adjustment of the position of the vibrating mechanism 2, ensuring that the vibrating rod can accurately align with the target position of precast components of different specifications.

[0037] Specifically, the adjusting groove 2311 is a straight groove radially opened along the toothed ring 31. The cross-sectional shape of the sliding block 232 matches the adjusting groove 2311, allowing it to slide smoothly within the adjusting groove 2311. The fastener 233 includes bolts or clamping mechanisms for fixing the sliding block 232 to a designated position in the adjusting groove 2311. The linear drive module 234 includes a lifting drive device, whose bottom is connected to the sliding block 232 and whose upper part is connected to the rotating assembly 24. The adjustment of the position of the sliding block 232 directly affects the radial position of the vibrating mechanism 2. When processing precast cylindrical components of different diameters, the operator loosens the fastener 233, adjusts the position of the sliding block 232 in the adjusting groove 2311 manually or automatically, and then tightens it to fix it.

[0038] In one specific embodiment, for a small cylindrical precast component with a diameter of 1.5 meters, the sliding block 232 moves inward toward the adjusting groove 2311, shortening the distance between the vibrating mechanism 2 and the center of the platform 1; for a large cylindrical precast component with a diameter of 3 meters, the sliding block 232 moves outward toward the adjusting groove 2311, increasing the distance between the vibrating mechanism 2 and the center of the platform 1. Through radial position adjustment, it is ensured that the vibrating mechanism 2 can always be aligned with the optimal vibration position of the ear plate, achieving precise vibration positioning regardless of changes in the precast component specifications.

[0039] In some embodiments, the mounting bracket 231 is provided with a support wheel 235, which abuts against the top of the platform 1.

[0040] In this invention, a support wheel 235 is provided on the fixing frame 231. The support wheel 235 abuts against the top of the platform 1, providing radial support to the platform 1 during the rotation of the toothed ring 31, preventing radial displacement or swaying of the platform 1. The rolling contact method of the support wheel 235 ensures the free rotation of the toothed ring 31 while providing the necessary support force, maintaining the relative positional stability between the platform 1 and the toothed ring 31, and ensuring the positioning accuracy of the vibration process.

[0041] Specifically, the support wheel 235 adopts a rolling bearing structure, allowing it to rotate freely while supporting the platform 1, thus reducing frictional resistance. The rim of the support wheel 235 forms rolling contact with the top of the platform 1. When the toothed ring 31 drives the fixed frame 231 to rotate, the support wheel 235 rolls on the top of the platform 1, avoiding sliding friction. The placement of the support wheel 235 is calculated to ensure a reasonable distribution of supporting force. The platform 1 bears the weight of the casting mold a and the concrete, and also withstands vibration loads during vibration. The radial support of the support wheel 235 prevents the platform 1 from moving unstably under these loads.

[0042] In one specific embodiment, when the vibrating mechanism 2 performs strong vibration on a certain ear plate position, the vibration and reaction force may cause the platform 1 to wobble radially, affecting the vibration accuracy and mold stability. The contact between the support wheel 235 and the top of the platform 1 provides radial constraint, restricting the platform 1 to the designed position and maintaining stability even under large vibration loads. At the same time, the rolling characteristics of the support wheel 235 do not hinder the rotational movement of the toothed ring 31, ensuring the flexibility of angular positioning.

[0043] In some embodiments, a support mechanism 4 is also included, comprising: a base 41; a support column 42, the bottom of which is fixedly connected to the base 41 and the top of which is ball-jointed to the platform 1, the ball-joint connection allowing the platform 1 to tilt relative to the support column 42; and a plurality of support legs 43 connected to the bottom of the toothed ring 31, the bottom of which is provided with rollers 44 that abut against the top of the base 41; wherein, when the horizontal section a2 is vibrated, the platform 1 tilts so that the horizontal section a2 is in a relatively low position, which facilitates the discharge of air bubbles in the horizontal section a2.

[0044] In this invention, the support mechanism 4 includes a base 41, a column 42, and multiple support legs 43. The top of the column 42 is connected to the platform 1 via a ball joint, allowing the platform 1 to tilt relative to the column 42. The multiple support legs 43 are connected to the bottom of the toothed ring 31 and abut against the top of the base 41 via rollers 44. When the horizontal section a2 is vibrated, the platform 1 tilts, placing the horizontal section a2 in a relatively low position to facilitate the discharge of air bubbles. The ball joint connection provides the platform 1 with a degree of freedom for tilting, and the cooperation between the support legs 43 and the rollers 44 ensures the stability and controllability of the tilting process. By tilting the platform 1, the mold posture is changed, and gravity is used to promote the discharge of air bubbles in the concrete.

[0045] Specifically, the ball joint connection allows the platform 1 to tilt in any direction within a certain angle range, with the tilt center located at the ball joint connection point. Rollers 44 at the bottom of the support leg 43 form a rolling support with the top of the base 41. When the platform 1 tilts, the rollers 44 roll on the base 41 to adapt to the position change. The concrete in the horizontal section a2 becomes more fluid under vibration. When this section is at a relatively low position, air bubbles in the concrete move upwards under buoyancy and are discharged from the higher end of the horizontal section a2, preventing air bubbles from remaining inside the horizontal section a2. The tilt angle of the platform 1 can be adjusted according to the geometric characteristics of the horizontal section a2 and the concrete properties.

[0046] In one specific embodiment, for ear plates with a large horizontal extension length, under traditional horizontal vibration methods, air bubbles tend to accumulate at the distal end of the ear plate and are difficult to expel, forming honeycomb-like defects. By tilting the platform 1 towards the ear plate, the distal end of the ear plate is positioned lower and the proximal end higher. Under the combined action of vibration and gravity, the air bubbles move towards the proximal end and are expelled. The tilt angle is typically controlled within the range of 5-15 degrees, ensuring effective air bubble expulsion while preventing concrete loss from the mold.

[0047] In some embodiments, a plurality of support legs 43 are evenly distributed along the circumference of the toothed ring 31.

[0048] In this invention, multiple support legs 43 are evenly distributed along the circumference of the toothed ring 31, achieving uniform distribution of the support load and mechanical balance of the support structure. The circumferentially distributed layout ensures that the load borne by each support leg 43 is basically equal, avoiding local stress concentration, improving the load-bearing capacity and structural stability of the support system, and extending the service life of the equipment.

[0049] Specifically, the number of support legs 43 is typically four or six, evenly distributed along the circumference of the toothed ring 31. Each support leg 43 bears both the vertical and tilting components of the load from the toothed ring 31, and the circumferential distribution ensures that the load is evenly distributed among the support legs 43. The bending moment generated by the toothed ring 31 under the weight of the platform 1 and the concrete is also balanced by the evenly distributed support legs 43, preventing excessive deformation of the toothed ring 31. The evenly distributed layout also ensures the mechanical symmetry of the platform 1 when tilted, making the tilting movement smoother and more controllable. When the platform 1 carries large precast components and the total weight reaches several tons after being loaded with concrete, if the distribution of the support legs 43 is uneven, some support legs 43 will bear excessive loads and may deform or be damaged. By evenly distributing four support legs 43 along the circumference of the toothed ring 31 at 90 degrees, each support leg 43 bears approximately one-quarter of the total load, resulting in a reasonable load distribution and a safe and reliable structure.

[0050] In some embodiments, the plurality of support legs 43 include: a first telescopic support leg 431, adjacent to the lifting bracket 23, which can extend and retract along the axial direction of the toothed ring 31; a second telescopic support leg 432, which is disposed opposite to the first telescopic support leg 431 and can extend and retract along the axial direction of the toothed ring 31; and two fixed support legs 433, which are disposed opposite to each other between the first telescopic support leg 431 and the second telescopic support leg 432; wherein the tilt angle and tilt direction of the platform 1 are controlled by the differential extension and retraction of the first telescopic support leg 431 and the second telescopic support leg 432.

[0051] In this invention, the multiple support legs 43 include a first telescopic support leg 431, a second telescopic support leg 432, and two fixed support legs 433. The first telescopic support leg 431 is disposed adjacent to the lifting bracket 23, and the second telescopic support leg 432 is disposed opposite to the first telescopic support leg 431. By shortening the first telescopic support leg 431 and extending the second telescopic support leg 432, the platform 1 forms a fixed tilt angle. Since the support legs 43 are fixed on the toothed ring 31 and rotate together with the toothed ring 31, the platform 1 maintains a constant tilt state throughout the entire ear plate vibration process, providing consistent air bubble discharge conditions for all horizontal sections a2.

[0052] Specifically, the first telescopic support leg 431 and the second telescopic support leg 432 can extend and retract along the axial direction of the toothed ring 31 to change the support height. Before the ear plate vibration begins, the first telescopic support leg 431 is shortened to a preset length, and the second telescopic support leg 432 is extended to a preset length. The platform 1 is tilted around the ball joint connection point towards the first telescopic support leg 431 to form a fixed angle. The two fixed support legs 433 provide stable foundation support. Since the first telescopic support leg 431 is located near the lifting bracket 23, the tilt of the platform 1 keeps the area near the lifting bracket 23 in a relatively low position, which is conducive to the discharge of air bubbles in the horizontal section a2 on this side. When the rotating mechanism 3 drives the toothed ring 31 to rotate, the support leg 43 rotates with the toothed ring 31, and the tilt direction of the platform 1 also rotates accordingly, always keeping the currently vibrating horizontal section a2 in a relatively low position.

[0053] In one specific embodiment, for the four ear plates distributed along the circumference of the cylinder, after the first telescopic leg 431 is shortened and the second telescopic leg 432 is extended, the platform 1 tilts 10 degrees toward the direction of the first telescopic leg 431. When the rotating mechanism 3 positions the vibrating mechanism 2 to the position of the first ear plate, the ear plate is on the lower side of the platform 1, and air bubbles move to the higher side and are discharged during vibration. When rotating to the position of the second ear plate, the tilt direction of the platform 1 also rotates 90 degrees, and the second ear plate is also on the lower side. And so on, all four ear plates can be vibrated under the same tilt conditions. After all ear plates have been vibrated, the two telescopic legs are adjusted to the same length, and the platform 1 returns to a horizontal state for regular vibration of the top area.

[0054] In this embodiment of the invention, the same tilting vibration conditions can be provided for all horizontal sections a2 by adjusting the telescopic outriggers once. As the rotation mechanism 3 is positioned at an angle, the tilting direction of the platform 1 automatically corresponds to the current vibration position, realizing the automated unification of vibration conditions for multiple horizontal sections a2, simplifying the operation process, and ensuring the consistency of vibration quality of each ear plate.

[0055] In some embodiments, the first telescopic outrigger 431 and the second telescopic outrigger 432 are hydraulically driven.

[0056] In this invention, the first telescopic outrigger 431 and the second telescopic outrigger 432 are hydraulically driven. The hydraulic system provides the telescopic outriggers with powerful driving force and precise position control. The hydraulic drive features fast response speed, high adjustment accuracy, and strong load-bearing capacity. It can adjust the platform 1 to an inclined state before the vibration begins and maintain stability throughout the entire ear plate vibration process, meeting the long-term tilting requirements under heavy load conditions.

[0057] Specifically, the hydraulic drive system includes components such as a hydraulic pump, hydraulic cylinders, control valve assembly, and hydraulic oil tank. The hydraulic cylinders are installed inside the telescopic outriggers, and the length of the outriggers changes through the extension and retraction of the piston rods. Before the ear plate vibration begins, the first telescopic outrigger 431 is shortened to a set length by the hydraulic cylinder, and the second telescopic outrigger 432 is extended to a set length by the hydraulic cylinder, causing the platform 1 to tilt towards the first telescopic outrigger 431. The locking function of the hydraulic system ensures that the outriggers remain at a fixed length after adjustment, maintaining a constant tilt angle of the platform 1 throughout the ear plate vibration process.

[0058] In some embodiments, the top of the platform 1 is provided with a positioning groove 11 for positioning the casting mold a, and the positioning groove 11 is coaxially arranged with the toothed ring 31.

[0059] In this invention, the positioning groove 11 on the top of the platform 1 is used to position the casting mold a. The positioning groove 11 is coaxially arranged with the toothed ring 31 to ensure precise alignment between the casting mold a and the rotating system. The coaxial arrangement ensures that the central axis of the mold coincides with the rotation axis of the toothed ring 31, so that the vibrating mechanism 2 can always accurately align with the positions of each horizontal segment a2 of the mold during rotation, avoiding the impact of positioning deviation on the vibration quality.

[0060] Specifically, the shape of the positioning groove 11 matches the bottom contour of the casting mold a, typically a circular groove, with its center coinciding with the center of the platform 1. The rotation center of the toothed ring 31 also coincides with the center of the platform 1, forming a coaxial configuration. After the casting mold a is placed in the positioning groove 11, the central axis of the mold naturally aligns with the rotation axis. The depth and size design of the positioning groove 11 ensures stable positioning of the mold, preventing displacement or rotation during vibration. The coaxial arrangement ensures that when the rotating mechanism 3 drives the vibration mechanism 2 to rotate around the center of the mold, the positional relationship of each horizontal segment a2 relative to the vibration mechanism 2 remains consistent.

[0061] In one specific embodiment, for a cylindrical precast component with four ear plates evenly distributed circumferentially, after the mold is precisely positioned by the positioning groove 11, the four ear plates are located at 0 degrees, 90 degrees, 180 degrees, and 270 degrees respectively. The vibration mechanism 2, through precise angle control of the rotation mechanism 3, can accurately align with the position of each ear plate sequentially. If there is a deviation in the mold positioning, the vibration mechanism 2 may not be able to accurately align with the center of the ear plate, affecting the vibration effect and quality consistency. The coaxial arrangement of the positioning groove 11 and the toothed ring 31 achieves precise mold positioning, eliminates human positioning errors, ensures the accurate correspondence between the vibration mechanism 2 and each part of the mold, and improves the vibration accuracy and product quality consistency.
