Description

Technical Field

[0001] The utility model relates to the technical field of shock absorption, in particular to a shock absorption base for equipment. Background Art

[0002] In the modern construction industry, shock-absorbing bases are widely used in the installation of various equipment to reduce the transmission of vibrations generated during equipment operation to building structures and the surrounding environment.

[0003] At present, the shock-absorbing base widely used in the market mainly adopts spring shock-absorbing devices, which absorb and buffer the vibration generated during the operation of the equipment through the elastic characteristics of the spring, thereby reducing the transmission of vibration to the outside world.

[0004] However, the spring shock absorber mainly absorbs vibration energy through the elastic deformation of the spring, but the inherent characteristics of the spring make it have a certain reaction force when it is vibrated, which makes the equipment easy to shake during operation and unable to maintain a stable state, especially when the load changes greatly. When the equipment runs in this unstable state, it not only affects the work efficiency, but also may cause damage to the precision components inside the equipment and shorten the service life of the equipment.

[0005] Therefore, there is an urgent need for a more effective shock-absorbing base that can comprehensively improve the shock-absorbing effect, ensure the stable operation of the equipment, extend its service life, and reduce maintenance costs.

[0006] Based on this, it is necessary to study a shock-absorbing base for equipment. Utility Model Content

[0007] In view of this, the purpose of the utility model is to provide a device shock-absorbing base, which can effectively solve the problem that the existing spring shock-absorbing base cannot effectively reduce the vibration amplitude of the device itself.

[0010] The upper frame and the lower frame are arranged at intervals in the upper and lower parts and are fixedly connected by pillars located on the left and right sides;

[0011] The upper prestressed plate and the lower prestressed plate are both arranged horizontally between the upper frame and the lower frame;

[0012] The left end of the upper prestressed plate is fixedly connected to the lower frame, and the right end is arranged on the lower frame, and the right end can be adjusted left and right relative to the lower frame;

[0013] Both ends of the lower prestressed plate are arranged on the lower frame, and both ends can be adjusted left and right relative to the lower frame;

[0014] The upper prestressed plate and the lower prestressed plate are both bent into an arch shape, the upper prestressed plate is located between the two pillars, and the lower prestressed plate is located between the upper prestressed plate and the lower frame;

[0015] The arch of the upper prestressed plate abuts against the lower end surface of the upper frame, and the arch of the lower prestressed plate abuts against the lower end surface of the upper prestressed plate.

[0016] Furthermore, the cross section of the lower frame is I-shaped, including an upper edge plate, a lower edge plate and a web plate, and the upper edge plate and the lower edge plate are vertically fixedly connected with the web plate;

[0017] The upper edge plate is provided with three groups of adjusting flat holes corresponding to the right end of the upper prestressed plate and the two ends of the lower prestressed plate respectively;

[0018] Adjustment bolts are provided between the right end of the upper prestressed plate and the corresponding adjustment flat hole, and between the two ends of the lower prestressed plate and the corresponding adjustment flat holes;

[0019] The right end of the upper prestressed plate and both ends of the lower prestressed plate are adjusted left and right and fixed on the lower frame through adjusting bolts and adjusting flat holes.

[0020] Furthermore, a tensioning slider is fixedly connected to the lower surface of the right end of the upper prestressed plate, the tensioning slider is vertically slidably arranged in the adjusting flat hole, and the lower end of the tensioning slider extends downward out of the adjusting flat hole;

[0021] The side wall of the web is fixedly connected with a fixing seat, the fixing seat is located on the left side of the tensioning slider, and a first tensioning bar is passed through and connected between the fixing seat and the lower end of the tensioning slider.

[0022] Furthermore, both left and right ends of the lower prestressed plate are fixedly connected with vertical tension plates, and a second tensioning bar is connected and passed through the two tension plates;

[0023] A horizontal adjustment plate is fixedly connected to the bottom of the tensioning plate;

[0024] The adjusting bolts are passed through the adjusting plate and the adjusting flat holes to fix the two ends of the lower prestressed plate to the lower frame.

[0025] Furthermore, both ends of the first tie bar and both ends of the second tie bar are provided with threaded sections;

[0026] The threaded sections at both ends of the first tensioning bar respectively pass through the fixing seat and the tensioning slider and are threadedly connected to the tensioning nut;

[0027] Two ends of the second tensioning bar pass through two tensioning plates and are threadedly connected with tensioning nuts.

[0028] The beneficial effects of the above technical solution are:

[0029] (1) The upper prestressed plate and the lower prestressed plate of the utility model are designed to be arched, the arch top of the upper prestressed plate abuts against the lower end surface of the upper frame, and the arch top of the lower prestressed plate abuts against the lower end surface of the upper prestressed plate, forming a double arch structure with good mechanical properties, which can effectively disperse and transmit the vibration energy generated by the equipment to various parts of the base, reducing local stress concentration.

[0030] (2) The upper prestressed plate and the lower prestressed plate of the utility model are in a compressed state in the initial state. The upper prestressed plate and the lower prestressed plate can continuously provide upward prestress for the upper frame. The prestress caused by the initial compression can offset part of the vibration stress generated during the operation of the equipment, thereby improving the structural rigidity and stability.

[0031] (3) The design of the support column of the utility model provides a stable rigid fixed foundation for the upper frame. Combined with the supporting function of the upper prestressed plate and the lower prestressed force, the overall stiffness of the structure is directly improved. The increase in stiffness means that the deformation of the structure under the vibration of the equipment can be reduced, and the vibration caused by the equipment can be better resisted.

[0032] (4) The elastic deformation characteristics of the upper prestressed plate and the lower prestressed plate of the utility model enable them to absorb vibration energy and convert it into friction heat energy of internal molecules when subjected to equipment vibration, thereby dissipating part of the energy and reducing the vibration transmitted to the equipment. The upper prestressed plate is located between the two pillars, and the lower prestressed plate is located between the upper prestressed plate and the lower frame. The arches abut against each other to form a multi-layer prestressed structure. This multi-layer prestressed structure can absorb and disperse the vibration energy layer by layer under the vibration generated by the operation of the equipment, thereby reducing the vibration amplitude of the equipment.

[0033] (5) The utility model can adjust the installation position and prestressing force of the prestressed plate according to the specific situation by adjusting the bolts and adjusting the flat holes, ensuring that it is always in the best state. This flexibility allows the base to be adjusted at any time during the operation of the equipment to cope with different vibration conditions.

[0034] In summary, the utility model significantly improves the overall stiffness of the base and its ability to absorb vibration energy through the design of two-layer prestressed plates and the application of prestress, effectively solving the problem that the existing spring shock-absorbing base cannot effectively reduce the vibration amplitude of the equipment itself, and has significant advantages and application prospects in reducing the vibration of the equipment itself and improving the stability of equipment operation.
