Description

Technical Field

[0001] This utility model relates to the field of high-frequency vibration table technology, specifically to a high-frequency vibration table. Background Technology

[0002] A vibration table, also known as a vibration exciter or vibration generator, is a device that generates mechanical vibration using electric, electrohydraulic, piezoelectric, or other principles. Its principle involves inputting an excitation signal into a coil placed in a magnetic field to drive a worktable connected to the coil. Electric vibration tables are mainly used for vibration measurements above 10Hz, and can excite a maximum pressure of 200N. In the frequency range below 20Hz, electrohydraulic vibration tables are commonly used, where the nature of the vibration signal is controlled by an electro-servo system. Hydraulic drive systems can provide larger displacements and impact forces.

[0003] A high-frequency vibration table is a device that can vibrate materials to make them denser. Although existing vibration tables are becoming more and more advanced, in actual use, the table has a large amplitude and low vibration frequency. Due to the problem of vibration inertia, the connection stability is prone to problems. Moreover, in the early stage of vibration, the cementitious material often spills out from the table, affecting the cleanliness of the working environment and causing unnecessary material waste.

[0004] Therefore, it is necessary to provide a high-frequency vibration table to solve the above-mentioned technical problems. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a high-frequency vibration table, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution The specific technical solution adopted in this utility model is as follows: The high-frequency vibration table includes a main body with a clearance cavity on its surface, inside which the vibration table body is installed. Multiple springs are evenly spaced around the periphery of the vibration table body, with the other end of each spring fixed to the inner wall of the clearance cavity. When the high-frequency vibration motor drives the vibration table body to vibrate, the springs act as buffers and dampers, reducing the impact of vibration inertia and enhancing connection stability. Corrugated covers are fitted around the springs to prevent dust and materials from entering and affecting their performance. A high-frequency vibration motor is mounted on the bottom surface of the vibration table body, providing high-frequency vibration power for the entire device. A conical platform is mounted on the top surface for placing the material to be processed; its unique shape helps improve the material compaction effect. Preferably, a mounting frame is installed on the top surface of the device body, and an electric telescopic rod is mounted on the mounting frame; a protective cover is placed on the vibrating table body, and a horizontal plate is installed on the top surface of the protective cover. The output end of the electric telescopic rod is fixedly connected to the top surface of the horizontal plate. Before vibration operation, the electric telescopic rod extends, causing the protective cover to descend and enclose the vibrating table body, preventing materials from spilling out due to inertia in the initial stage of vibration; after the operation is completed, the electric telescopic rod retracts, causing the protective cover to rise, facilitating material loading and unloading and equipment maintenance operations for operators. Preferably, a limiting rod is vertically installed on the top surface of the vibration table body near the edge, and a corresponding limiting hole is formed on the bottom surface of the protective cover. During the descent of the protective cover, the limiting rod and the limiting hole cooperate to achieve precise positioning, ensuring that the protective cover can accurately cover the vibration table body and guarantee the protective effect.

[0007] Preferably, a discharge frame is installed at the bottom of the device body to collect materials scattered during vibration, facilitating subsequent unified cleaning; at the same time, multiple sets of support legs are installed at the bottom of the device body, and the multiple support legs are evenly distributed on the bottom surface of the device body to provide stable support for the equipment and ensure the stability of the equipment during operation. Preferably, the device body is equipped with a controller, and the operator sends start, stop and other signals to the high-frequency vibration motor through the controller to achieve precise control of the equipment's operating status, thereby controlling the working process of the high-frequency vibration table.

[0008] Compared with related technologies, the high-frequency vibration table provided by this utility model has the following beneficial effects: (1) In this utility model, the high-frequency vibration table is installed in the relief cavity of the device body, and springs and corrugated covers are set on its periphery. The springs can effectively buffer the impact force during the vibration process, reduce the influence of vibration inertia, and improve the connection stability. The high-frequency vibration motor can provide high-frequency vibration, which, together with the conical table, can improve the material compaction effect. Compared with the existing vibration table, it effectively solves the problems of large table amplitude and low vibration frequency.

[0009] (2) In this utility model, the mounting bracket on the top of the device body is equipped with an electric telescopic rod, which is connected to the protective cover. During vibration operation, the electric telescopic rod can control the protective cover to descend, enclosing the main body of the vibration table, preventing the gel from spilling from the table surface in the early stage of vibration, keeping the working environment clean, and avoiding material waste; after the operation is completed, the electric telescopic rod can raise the protective cover, which facilitates the loading and unloading of materials and the maintenance of equipment, and improves the convenience of operation.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0014] In the description of this application, it should be understood that the terms "upper", "lower", "inner", "outer", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0015] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" or "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0016] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0017] Example 1 refer to Figure 1-4 The high-frequency vibration table uses the main body 1 as its basic frame. A suitable-sized clearance cavity is pre-machined into its surface. The shape and size of this clearance cavity are precisely designed according to the external shape of the vibration table body 7, providing installation space for the vibration table body 7. The vibration table body 7 is installed inside the clearance cavity. During installation, it is necessary to ensure that the vibration table body 7 is centered within the clearance cavity to ensure the balance of subsequent vibrations. Multiple springs 14 are evenly spaced around the sides of the vibration table body 7. These springs 14 are installed by welding or bolting, with one end of each spring firmly fixed to a pre-set connection point on the side of the vibration table body 7, and the other end fixed to a corresponding connection structure on the inner wall of the clearance cavity. The elastic coefficient of the springs 14 is precisely calculated and selected. When the high-frequency vibration motor 9 drives the vibration table body 7 to generate high-frequency vibration, it can effectively buffer the impact force generated by the vibration, absorb vibration energy through its own elastic deformation, reduce the impact of vibration inertia on the equipment connection parts, and thus enhance the connection stability between the vibration table body 7 and the device body 1. To prevent dust, materials, and other impurities from entering the springs 14 and affecting their normal working performance and service life, a corrugated cover 11 is fitted onto the outside of the springs 14. The corrugated cover 11 is fixed to the outside of the springs 14 by a detachable snap-fit ​​connection or an elastic wrapping method, which can tightly fit the springs 14 and form an effective protective barrier. A high-frequency vibration motor 9 is installed on the bottom surface of the vibration table body 7 via bolt connections. During installation, the flatness and verticality of the motor mounting surface must be strictly ensured to guarantee that the vibration output from the motor can be accurately and stably transmitted to the vibration table body 7, providing high-frequency vibration power for the entire equipment. A conical platform 12 is installed on the top surface of the vibration table body 7. The conical platform 12 is fixed by welding or inlay. Its unique conical shape can change the movement trajectory of the material during vibration, causing the material to concentrate towards the center during vibration, which helps to improve the material compaction effect. Compared with a planar structure, it can more effectively achieve the densification of materials.

[0018] Example 2 refer to Figure 1-4 The mounting frame 3 is installed on the top surface of the device body 1 by welding or bolting. The structural design of the mounting frame 3 must meet the requirements of bearing the weight of the electric telescopic rod 4 and the protective cover 2, as well as the forces generated during operation. The electric telescopic rod 4 is installed on the mounting frame 3. The installation of the electric telescopic rod 4 adopts a hinged or flanged connection to ensure that it can extend and retract flexibly and has sufficient connection strength. A protective cover 2 is placed on the main body 7 of the vibration table. A horizontal plate 5 is installed on the top surface of the protective cover 2 by welding or bolting. The horizontal plate 5 is fixedly connected to the output end of the electric telescopic rod 4 by bolts or pins. Before vibration operation, the operator starts the electric telescopic rod 4 through the controller 6. The electric telescopic rod 4 extends, and its output thrust drives the horizontal plate 5 and the protective cover 2 to descend synchronously, enclosing the main body 7 of the vibration table inside the protective cover 2. This effectively prevents materials from spilling out due to inertia in the early stages of vibration, protecting the cleanliness of the working environment and avoiding material waste. After the vibration operation is completed, the electric telescopic rod 4 retracts, and the pulling force drives the protective cover 2 to rise, fully exposing the main body 7 of the vibration table, facilitating material loading and unloading and equipment maintenance operations. Throughout the entire lifting and lowering process, the extension accuracy and stability of the electric telescopic rod 4 directly affect the lifting effect and protective performance of the protective cover 2.

[0019] Example 3 See Figure 1-4 A limiting rod 13 is vertically installed near the edge of the top surface of the vibration table body 7 using welding or bolts. During installation, the verticality and positional accuracy of the limiting rod 13 must be ensured. A limiting hole 15 is formed on the bottom surface of the protective cover 2 corresponding to the position of the limiting rod 13. The size of the limiting hole 15 is adapted to the limiting rod 13, and the hole wall is smooth to reduce friction. During the descent of the protective cover 2, the limiting rod 13 and the limiting hole 15 cooperate with each other. When the protective cover 2 descends to a certain position, the limiting rod 13 inserts into the limiting hole 15, providing precise positioning and ensuring that the protective cover 2 accurately covers the vibration table body 7, guaranteeing the protective effect. This also prevents the protective cover 2 from shifting or tilting during descent, which could affect the normal operation of the equipment.

[0020] Example 4 refer to Figure 1-4 The discharge frame 10 is installed at the bottom of the device body 1 by welding or bolting. The installation position and angle of the discharge frame 10 are carefully designed to ensure effective collection of materials scattered during vibration. The opening direction and tilt angle of the discharge frame 10 facilitate the smooth sliding of materials into the collection area, making subsequent unified cleaning easier. Simultaneously, multiple sets of support legs 8 are installed at the bottom of the device body 1. The support legs 8 are fixed to the bottom surface of the device body 1 by bolting or welding, and the multiple support legs 8 are evenly distributed. Their length and strength have been calculated to provide stable support for the equipment, ensuring that the equipment remains horizontal and stable during operation, and preventing vibration effects and equipment lifespan from being affected by equipment shaking.

[0021] Example 5 refer to Figure 1-4 The controller 6 is mounted on the main body 1 using bolts or clips. The controller 6 is connected to the high-frequency vibration motor 9 via electrical wiring, using a plug, socket, or terminal block. The operator sends start, stop, and speed adjustment signals to the high-frequency vibration motor 9 through the interface on the controller 6. The internal control circuit of the controller 6 processes and converts the signals, transmitting the electrical signals to the high-frequency vibration motor 9 to achieve precise control of the equipment's operating status and thus control the working process of the high-frequency vibration table. Simultaneously, the controller 6 can also communicate with other components such as the electric telescopic rod 4, enabling coordinated operation between components and ensuring the entire equipment operates according to predetermined programs and requirements. Ultimately, this achieves the technical effects claimed in the patent, such as improved vibration effect, enhanced equipment stability, and convenient operation.

[0022] The control circuit of controller 6 can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0023] The working principle of the raw material preheating device based on waste heat in oil refining provided by this utility model is as follows: When the high-frequency vibration table is in operation, the material to be processed is first placed on the conical platform 12 at the top of the vibration table body 7. The operator starts the equipment through the controller 6 installed on the device body 1. The controller 6 sends a start signal to the high-frequency vibration motor 9, and the high-frequency vibration motor 9 starts to work, generating high-frequency vibration and transmitting the vibration to the vibration table body 7. The main body 7 of the vibration table undergoes high-frequency vibration driven by the high-frequency vibration motor 9. Because the springs 14 mounted on its peripheral side are connected to the inner wall of the clearance cavity, the springs 14 can buffer and dampen vibrations during the process, effectively reducing the impact of vibration inertia on the equipment connection parts and ensuring the stability of equipment operation. Simultaneously, the corrugated cover 11 sleeved on the outside of the springs 14 can prevent dust, materials, etc., from entering the springs 14, protecting them for normal operation. During the vibration of the main body 7 of the vibrating table, the electric telescopic rod 4 on the mounting frame 3 can be extended or retracted as needed. Before vibration begins, the electric telescopic rod 4 extends, causing the protective cover 2 to descend and completely cover the main body 7 of the vibrating table, preventing materials from spilling off the table surface due to vibration inertia in the early stages of vibration. After the materials are compacted, the electric telescopic rod 4 retracts, causing the protective cover 2 to rise, making it convenient for operators to remove the processed materials. Furthermore, the limiting rod 13 at the top of the vibration table body 7 and the limiting hole 15 at the bottom of the protective cover 2 cooperate with each other to play a precise positioning role during the descent of the protective cover 2, ensuring that the protective cover 2 can accurately cover the vibration table body 7. A small amount of loose material generated during vibration will fall into the discharge frame 10 at the bottom of the device body 1 for easy collection and cleaning. Throughout the entire operation, multiple sets of support legs 8 at the bottom of the device body 1 provide stable support for the equipment, ensuring safe operation.

The mechanical parts and electrical equipment adopt conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
