Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for precast concrete components, and in particular to a vibrator for precast permeable frames. Background Technology

[0002] In waterway improvement projects, permeable structures are often installed to protect the foundations of hydraulic structures such as embankments and bridge piers from continuous erosion and damage by water flow and waves. These structures reduce wave energy and promote sediment deposition to form a natural protective layer. As an important protective structure, permeable frames are formed by casting concrete using molds. The commonly used structure is a triangular pyramid composed of three base columns and a triangular base frame. This structure, with its permeable characteristics, allows water to partially pass through its internal gaps rather than being completely blocked, thereby effectively weakening the impact energy of the water flow and slowing down the flow velocity. At the same time, its sturdy concrete material and the reinforced triangular structure at the bottom can be firmly anchored to the foundation, and the space formed inside provides an ideal place for sediment deposition, ultimately achieving the protective effect of slowing the flow, promoting sedimentation, and stabilizing the foundation.

[0003] However, in the precast concrete production process of the aforementioned permeable frame, in order to ensure the density and uniformity of the concrete inside the mold, it is necessary to use a vibrator to compact the concrete inside. The common practice is to directly weld the vibrator to the surface of the mold column, or to fasten it using detachable methods such as bolts and clips. Both of these fixing methods have significant limitations: welding is not only extremely inconvenient to assemble and disassemble, but also affects the ease of demolding and service life of the mold. Once the vibration position is determined, it cannot be adjusted, making it difficult to meet the process requirements of uniform vibration of multiple mold columns. While bolts and clips can be disassembled, their installation and adjustment process is still cumbersome and time-consuming. The reserved installation holes strictly limit the flexibility of vibrator placement, making it impossible to adjust the position of the vibrator according to the actual situation, thus restricting the overall production efficiency and quality of precast components. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vibrator for prefabricated permeable frames, which solves the problems of existing vibrators being inconvenient to install and remove quickly after installation, and the inability to adjust the position of the vibrator according to actual conditions, thus restricting the overall production efficiency and quality of prefabricated components.

[0005] According to an embodiment of the present invention, a vibrator for prefabricating permeable frames includes a vibrating motor, an installation plate fixedly mounted on the bottom of the vibrating motor, and a fixed frame fixedly mounted on the bottom of the installation plate. A movable frame is detachably mounted on the bottom of the fixed frame. The width of the movable frame is adapted to that of the fixed frame and can be aligned with the fixed frame to form a closed frame structure. A locking mechanism is fixedly mounted on the fixed frame, which can quickly lock the movable frame to form a closed frame structure.

[0006] The technical principle of this utility model is as follows: When in use, the operator first determines the installation position of the vibrator according to the vibration requirements of the permeable frame concrete. Then, the inner side of the bottom fixed frame of the vibrator motor is attached to the surface of the mold column and inserted, and the bottom of the movable frame is attached to the fixed frame, so that the mold column is located in the enclosed space formed by the fixed frame and the movable frame. Then, the locking mechanism is operated to drive the movable frame to quickly close with the fixed frame, thereby forming a rigid closed frame structure that tightly surrounds the mold column. It is firmly held on the mold column by the overall rigidity and locking force, thereby realizing the rapid installation and reliable fixation of the vibrator at any specified position on the mold column.

[0007] Furthermore, the fixed frame is U-shaped, the movable frame is U-shaped or straight, and a first connecting plate and a second connecting plate are fixedly provided on both sides of the fixed frame and the movable frame, respectively. Clamping concave surfaces are provided on the opposite inner sides of the fixed frame and the movable frame.

[0008] Furthermore, the clamping concave surface includes a V-shaped surface, an arc-shaped surface, and a rectangular surface.

[0009] Furthermore, an anti-slip pad is fixedly covered on the clamping concave surface.

[0010] Furthermore, a magnet is fixedly disposed on the clamping concave surface.

[0011] Furthermore, the locking mechanism includes a locking post fixed to the first connecting plate and a locking sleeve slidably sleeved on the locking post. A locking block is fixedly provided on the outside of the locking sleeve. The bottom of the locking sleeve is connected to the first connecting plate by a spring. An eccentric wheel is rotatably provided on the top of the locking post, which can rotate to abut against or separate from the locking block. A handle is fixedly connected to one side of the eccentric wheel.

[0012] Furthermore, the second connecting plate is provided with a through groove at one end, which allows the locking sleeve to enter and slide when the movable frame and the fixed frame are closed.

[0013] Furthermore, a tightening rod is threadedly connected to one side of the fixing frame, a handle is fixedly connected to the outside of the tightening rod, and a pressure head is fixedly connected to the inside of the tightening rod.

[0014] Furthermore, the mounting plate has several mounting holes symmetrically arranged on both sides, and bolts are threaded through the mounting holes to fix the mounting frame.

[0015] Compared with the prior art, this utility model has the following advantages: by setting a locking mechanism to quickly close the separated fixed frame and movable frame, the vibrating motor can be clamped without relying on the reserved holes or welding points on the mold. At the same time, the closed frame structure can evenly distribute the excitation force generated by vibration and directly transmit it to the mold column, ensuring the tightness and stability of the device during vibration, thereby avoiding the problem of affecting the compaction of concrete due to the loosening of the vibrator, and significantly improving the work efficiency of concrete vibration and the overall precast quality.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-3 As shown in the figure, this utility model embodiment proposes a vibrator for prefabricating permeable frames. It is fixed on the mold column 1 at the bottom of the prefabrication mold of the permeable frame. The vibrator makes the concrete poured into the mold column 1 uniform and dense through vibration. Specifically, it includes a vibrating motor 2. The bottom of the vibrating motor 2 is fixedly provided with an installation plate 21. The bottom of the installation plate 21 is fixedly connected with a fixed frame 3. The inner contour of the fixed frame 3 is adapted to the shape of the mold column 1. The bottom of the fixed frame 3 is detachably provided with a movable frame 4. The width of the movable frame 4 is adapted to the fixed frame 3 and can be aligned with the fixed frame 3 to form a rigid closed frame structure that tightly surrounds the mold column 1. The fixed frame 3 is fixedly provided with a locking mechanism 5. The locking mechanism 5 can quickly lock the movable frame 4 to form a closed frame structure.

[0023] In this exemplary embodiment, after the operator inserts the fixed frame 3 into the mold column 1 from the side, the movable frame 4 can be driven to quickly close or separate by operating the locking mechanism 5. This allows the vibrating motor 2 to be quickly installed and disassembled at any position on the mold column 1 without relying on the reserved holes or welding points on the mold. At the same time, the closed frame structure can evenly disperse and transmit the excitation force generated by the vibrating motor 2 to the concrete inside the mold column 1. With its overall rigidity and large-area contact with the surface of the mold column 1, it ensures that the device does not loosen or shift under continuous vibration conditions. This not only ensures the uniformity and density of concrete vibration, but also significantly improves the efficiency of switching between multiple mold columns 1 and continuous vibration operations.

[0024] When using this utility model, the operator first determines the installation position of the vibrator according to the vibration requirements of the permeable frame concrete. Then, the inner side of the bottom fixing frame 3 of the vibrating motor 2 is attached to the surface of the mold column 1 and inserted. The movable frame 4 is attached to the bottom of the fixing frame 3, so that the mold column 1 is located in the enclosed space formed by the fixing frame 3 and the movable frame 4. Then, the locking mechanism 5 is operated to drive the movable frame 4 to quickly close with the fixing frame 3, thereby forming a rigid closed frame structure that tightly surrounds the mold column 1. It is firmly held on the mold column 1 by the overall rigidity and locking force, thereby realizing the rapid installation and reliable fixation of the vibrator at any specified position of the mold column 1.

[0025] like Figure 1-3 As shown, in another embodiment, the fixed frame 3 is specifically U-shaped with its opening facing downwards. The movable frame 4 is set to be U-shaped or straight plate-shaped according to actual needs. A first connecting plate 32 and a second connecting plate 41 are respectively fixed on both sides of the opening end of the fixed frame 3 and the corresponding ends of the movable frame 4 to provide a locking base for the locking mechanism 5. In particular, the fixed frame 3 and the movable frame 4 are respectively provided with clamping concave surfaces 31 on their relative inner sides. The shape of the clamping concave surface 31 matches the outer contour of the mold column 1. Depending on the permeable frame structure, the shape of the mold column 1 changes accordingly, so that the clamping concave surface 31 can specifically include a V-shaped surface, an arc-shaped surface, a rectangular surface, and other irregular structures. These surface structures can meet the high fit between the fixed frame 3 and the outer contour of various mold columns 1, improve the clamping force, and avoid local stress concentration or unstable clamping caused by shape mismatch. In addition, the clamping concave surface 31 increases the contact area to evenly distribute the vibration pressure, ensuring the efficient transmission of vibration energy to the interior of the concrete.

[0026] like Figure 1-3As shown, in another embodiment, an anti-slip pad is fixedly covered on the clamping concave surface 31. The anti-slip pad is preferably made of polyurethane rubber and is firmly attached to the clamping concave surface 31 by bonding or embedding. Based on the above configuration, when the fixed frame 3 and the movable frame 4 lock the mold column 1, the anti-slip pad undergoes elastic deformation under the locking force. This not only increases the static friction with the surface of the mold column 1 and effectively resists vibration and slippage during operation, but its flexible characteristics also prevent the clamping concave surface 31 from rigidly contacting the mold surface, thus avoiding damage to the mold surface.

[0027] like Figure 1-3 As shown, in another embodiment, a magnet is fixedly provided on the clamping concave surface 31. The magnet can be a monolithic structure to provide uniform adsorption force, or it can be distributed in a multi-point array to achieve more flexible stress dispersion. When the fixed frame 3 or the movable frame 4 is inserted into the base column of the mold, the magnet can use magnetic force to firmly pre-adsorb the fixed frame 4 or the movable frame 3 onto the surface of the mold column 1, thereby significantly improving the overall rigidity and anti-displacement capability of the device under continuous vibration conditions. Furthermore, the magnet is preferably set as an electromagnet with a high dustproof and shockproof rating. The electromagnet is controlled by an external power source. By controlling the electromagnet to be energized, a strong directional magnetic field can be generated instantaneously. Compared with permanent magnets, the electromagnet's magnetic characteristic of being able to switch on and off instantly can completely avoid magnetic adhesion interference during movement and disassembly, achieving efficient and controllable adsorption and separation.

[0028] like Figure 1-4As shown, in another embodiment, the locking mechanism 5 includes a locking post 51 fixed on the first connecting plate 32 and a locking sleeve 52 slidably sleeved on the locking post 51. The locking sleeve 52 can slide up and down along the locking post 51. A locking block 53 is fixedly provided on the outside of the locking sleeve 52. The shape of the locking block 53 can be flexibly set according to the actual situation. A working gap is provided between the locking block 53 and the first connecting plate 32. The working gap is greater than the thickness of the second connecting plate 41 so that the second connecting plate 41 can enter. The bottom of the locking sleeve 52 is connected to the first connecting plate 32 by a spring. The spring has a compressive force and can lift the locking block 53 in the non-working state to maintain the initial working gap. A fixing seat 55 surrounding the locking post 51 is fixedly provided on the first connecting plate 32. A gap is left between the fixing seat 55 and the locking post 51 for the locking sleeve 52 to slide into. The locking post 51 is positioned within this gap, and the fixed seat 55 protects and limits the spring. An eccentric wheel 54 is rotatably mounted on the top of the locking post 51, capable of rotating to abut against or separate from the locking block 53. The eccentric wheel 54 is rotatably connected to the locking post 51 via an eccentric shaft 511. A handle 541 is fixedly connected to one side of the eccentric wheel 54, and the handle 541 is installed radially perpendicular to the diameter of the eccentric shaft 511. Based on this configuration, when the locking mechanism 5 is locked, the eccentric wheel 54 passes the dead center, forming a mechanical self-lock. Its distal end presses down on the locking block 53, and the locking block 53 applies a clamping force to the second connecting plate 41, causing the handle 541 to rotate to a horizontal position. When the locking mechanism 5 is unlocked, the distal end of the eccentric wheel 54 moves upward, the locking block 53 releases its lock on the second connecting plate 41, and is pushed back to its original position by the spring, causing the handle 541 to rotate to a vertical position.

[0029] In this embodiment, the multidimensional vibration load generated by the vibratory motor 2 is transmitted to the fixed frame 3 through the mounting plate 21, and further transmitted to the movable frame 4 through the joint surface of the first connecting plate 32 and the second connecting plate 41. However, due to the self-locking characteristic of the eccentric wheel 54, the eccentric wheel 54 that crosses the dead point abuts against the second connecting plate 41. The abutting force is opposite to the direction of the vibration force, and the small displacement generated by the vibration cannot trigger the eccentric wheel 54 to rotate. This ensures that the locking force of the locking block 53 will not decrease under continuous and intense vibration conditions, thus ensuring the long-term stable fixation of the vibrator on the mold column 1. In other embodiments, an adjusting rod is fixedly provided on the top of the locking column 51, which can adjust the height of the locking column 51, change the initial distance between the eccentric wheel 54 and the locking block 53, and thus adjust the locking block 53 to achieve the desired height. The maximum locking force can also be adjusted by changing the size of the eccentric wheel 54 or the eccentric distance of the eccentric shaft 511, thereby increasing the applicability of the device. It is worth noting that the core of the concrete vibration process in this mold is to remove internal air through short-time and efficient vibration to ensure compaction, without the need for long-term continuous vibration of a single part. Based on this process characteristic, the locking mechanism 5 proposed in this embodiment, with its quick loading and unloading characteristics, perfectly meets the operational requirements for rapid switching of vibration points in production. It not only effectively ensures the instantaneous stability of clamping during each vibration, but also significantly improves the overall efficiency of multi-station cyclic operation by greatly reducing the loading and unloading time, thereby achieving simultaneous improvement in production efficiency and product quality while meeting process requirements.

[0030] like Figure 3-4 As shown, in another embodiment, the second connecting plate 41 is provided with a through groove 411. When the movable frame 4 and the fixed frame 3 are closed, the groove 411 can guide the locking sleeve 52 to slide smoothly into the groove from its open end. Based on the above setting, the operator can quickly complete the initial connection between the locking sleeve 52 and the second connecting plate 41 without precise alignment. The side wall of the groove 411 automatically constrains and corrects the relative position of the movable frame 4 and the fixed frame 3 during the sliding process, ensuring that the two are quickly and accurately aligned, which significantly simplifies the clamping process and improves the installation efficiency.

[0031] like Figure 1-3 As shown, in another embodiment, a tightening rod 6 is threadedly connected to one side of the fixed frame 3. A handle 61 is fixedly connected to the outside of the tightening rod 6, and a pressure head 62 is fixedly connected to the inside of the tightening rod 6. Based on the above configuration, by rotating the handle 61 to drive the tightening rod 6 to feed along its axial direction, the pressure head 62 can apply an independent radial clamping force to the side of the mold column 1 from the direction perpendicular to the action direction of the locking block 53, which effectively suppresses the circumferential micro-movement and axial slippage tendency that may occur in the device during the vibration process, and further enhances the fastening stability and reliability.

[0032] like Figure 1-2 As shown, in another embodiment, the mounting plate 21 is symmetrically provided with a plurality of mounting holes 211 on both sides, and bolts 212 are threaded through the mounting holes 211 and fixed to the fixing frame 3. Based on the above configuration, the symmetrically arranged mounting holes 211 can uniformly transmit vibration force and avoid local stress concentration. The bolt connection method provides significant convenience and versatility for the installation or later maintenance and replacement of different models of vibrating motors 2 while ensuring connection rigidity.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
