Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering, and particularly relates to a shock absorption device for civil engineering structures. Background Art

[0002] Civil engineering involves a wide range of fields, including but not limited to industrial and civil building engineering, municipal engineering, foundation engineering and underground engineering, and road engineering, etc. In order to meet the shock absorption requirements, shock absorption devices are generally required to be provided in civil engineering structures.

[0003] In the existing shock absorption device, such as the Chinese patent with the publication number CN214615738U, a shock absorption device for a civil engineering structure is mentioned, which includes a shock absorption box fixed on a base. A horizontal movable plate is arranged in the inner cavity of the shock absorption box. A strong spring is installed between the center of the lower surface of the movable plate and the bottom plate of the shock absorption box. The left and right sides of the upper surface of the movable plate are respectively connected to the bottoms of two vertical support columns. The support columns pass through the sliding holes opened on the upper surface of the shock absorption box and the tops are connected to the bottom of the top plate. A buffer spring is sleeved on the support column, and the two ends of the buffer spring are respectively fixed on the bottom surface of the top plate and the upper surface of the shock absorption box.

[0004] During the use of this shock absorption device, the strong spring is used to support the movable plate and the shock absorption box. After it is installed on the civil engineering structure, its support stability is relatively low, resulting in low strength of the civil engineering structure and affecting the construction of civil engineering. In addition, during the use of this shock absorption device, the cooperation between the support spring, the buffer spring and the strong spring is used for shock absorption, and the shock absorption structure is single, resulting in poor shock absorption performance of the device. Summary of the Utility Model

[0005] The purpose of the utility model is to solve at least one problem of the existing technology and propose a shock absorption device for civil engineering structures.

[0006] To achieve the above purpose, the utility model proposes a shock absorption device for civil engineering structures, which includes an upper seat frame, a lower seat frame, a shock absorption mechanism and a damper. Both the upper seat frame and the lower seat frame are connected by a mounting plate and a sleeve frame. The sleeve frame of the upper seat frame is inserted into the sleeve frame of the lower seat frame in a matching manner to form a mounting cavity. The shock absorption mechanism and the damper are both located in the mounting cavity. The shock absorption mechanism includes a plurality of telescopic frames, a connecting plate, a movable rod, a guiding rod, a fixing plate and a spring. The upper and lower ends of the telescopic frame are respectively connected to the inner walls of the mounting plates of the upper seat frame and the lower seat frame. Both ends of the connecting plate and the movable rod are connected to two telescopic frames on the same side. Both ends of the damper are connected to the connecting plate. Two fixing plates located on the same horizontal plane are connected by a guiding rod. The guiding rod passes through the movable rod. The spring is sleeved on the outside of the guiding rod, and the two ends of the spring abut against the movable rod. The fixing plate located in the upper position is connected to the inner wall of the mounting plate of the upper seat frame, and the fixing plate located in the lower position is connected to the inner wall of the mounting plate of the lower seat frame.

[0007] Preferably, the telescopic frame is formed by cross - connecting a plurality of movable plates.

[0008] Preferably, the upper and lower ends of the telescopic frame are respectively connected to the inner walls of the mounting plates of the upper seat frame and the lower seat frame through connecting blocks.

[0009] Preferably, the connecting plate is provided with a connecting seat for installing a damper.

[0010] Preferably, two parallel guide rods are connected between two fixing plates located on the same horizontal plane.

[0011] Preferably, the mounting plates of the upper seat frame and the lower seat frame are provided with mounting holes.

[0012] Advantages of the present utility model: By movably inserting two seat frames, a shock - absorbing mechanism is connected between the two seat frames. Through the expansion and contraction of the telescopic frame in the shock - absorbing mechanism and the movement of the movable rod and the connecting plate, the compression deformation of the spring is realized. The damper absorbs and dissipates the vibration energy of the structure to reduce the amplitude and duration of the structure. The combined action of the spring and the damper results in good overall shock - absorbing effect. The multi - point support function of the telescopic frame further improves the support stability for civil structures.

[0021] The following will describe the present utility model in detail in conjunction with the accompanying drawings.

[0022] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, a shock-absorbing device for civil engineering structures is provided, which includes an upper seat frame 1, a lower seat frame 2, a shock-absorbing mechanism, and a damper 8. Both the upper seat frame 1 and the lower seat frame 2 are connected by a mounting plate and a sleeve frame. The sleeve frame of the upper seat frame 1 is inserted into the sleeve frame of the lower seat frame 2 in a matching manner to form a mounting cavity. Both the shock-absorbing mechanism and the damper 8 are located in the mounting cavity. The shock-absorbing mechanism includes a telescopic frame 3, a connecting plate 4, a movable rod 5, a guide rod 6, a fixing plate 7, and a spring 9. The upper and lower ends of the telescopic frame 3 are respectively connected to the inner walls of the mounting plates of the upper seat frame 1 and the lower seat frame 2. Both ends of the connecting plate 4 and the movable rod 5 are connected to the two telescopic frames 3 on the same side. Both ends of the damper 8 are connected to the two connecting plates 4. The two fixing plates 7 on the same horizontal plane are connected by a guide rod 6. The guide rod 6 passes through the movable rod 5. The spring 9 is sleeved outside the guide rod 6, and both ends of the spring 9 abut against the movable rod 5. The fixing plate 7 in the upper position is connected to the inner wall of the mounting plate of the upper seat frame 1, and the fixing plate 7 in the lower position is connected to the inner wall of the mounting plate of the lower seat frame 2.

[0023] In actual use, the shock absorption mechanism includes four telescopic frames 3, two connecting plates 4, four movable rods 5, four guide rods 6, four fixing plates 7 and four springs 9.

[0024] In this embodiment, referring to Figure 2 , the telescopic frame 3 is formed by cross-connecting a number of movable plates. The telescopic frame 3 is similar to the telescopic folding structure of a telescopic clothes hanger, and the movable plates are connected by pins.

[0025] In this embodiment, referring to Figure 2 , the upper and lower ends of the telescopic frame 3 are respectively connected to the inner walls of the mounting plates of the upper seat frame 1 and the lower seat frame 2 through connecting blocks 31.

[0026] In this embodiment, referring to Figure 4 , the connecting plate 4 is provided with a connecting seat for installing the damper 8, and the end of the damper 8 and the connecting seat are connected by a pin.

[0027] In this embodiment, referring to Figure 2 , two parallel guide rods 6 are connected between two fixing plates 7 located on the same horizontal plane.

[0028] In this embodiment, referring to Figure 1 , the mounting plates of the upper seat frame 1 and the lower seat frame 2 are provided with mounting holes, and the setting of the mounting holes facilitates the installation and fixation of the upper seat frame 1 and the lower seat frame 2 to the civil engineering structure.

[0029] Working process of the present utility model:

[0030] During the working process of this civil engineering structure shock absorption device, the upper seat frame 1 is installed and fixed to the corresponding civil engineering structure. When the civil engineering structure generates vibrations during use, during the vibration process, the mounting plate and the sleeve frame of the upper seat frame 1 move downward, thereby pushing the connecting block 31 connected to this mounting plate downward. The movement of the connecting block 31 drives the movement of the movable plates of the telescopic frame 3 that is movably connected to it. When the movable plates move, they push the connecting plate 4 to move towards the direction close to the damper 8. After the connecting plate 4 moves, it pushes the connecting seat to squeeze the damper 8, causing it to contract to achieve a certain buffer and shock absorption effect. At the same time, the movable rod 5 moves along the guide rod 6 towards the direction close to the spring 9 under the drive of the movable plate, causing the spring 9 to be compressed. The compression of the spring 9 can also achieve a certain buffer and shock absorption effect. When the vibration ends, the damper 8 and the spring 9 return to their original positions, causing the movable rod 5 and the connecting plate 4 to return to their initial positions again, and finally causing the upper seat frame 1 to return to its initial position.

[0031] The above embodiments are illustrative of the present utility model, not limiting of the present utility model. Any solution obtained by simply transforming the present utility model belongs to the protection scope of the present utility model.
