[0004] Although the above patent effectively disperses the vertical pressure generated by the large-span steel structure, it does not solve the horizontal left and right deviation caused by the dispersion of vertical pressure. The support is prone to stress concentration and damage, thus causing safety hazards. Utility Model Content

[0005] In order to solve the horizontal left-right deviation caused by the existing steel structure support when dispersing the vertical pressure, the utility model provides a large-span steel structure support.

[0006] The technical solution of the utility model is achieved through the following solution: a large-span steel structure support, including a supporting base, a swinging top plate, a support platform, a first buffer device, a second buffer device and a plurality of inclined supporting devices, the supporting base is installed with a support platform, the swinging top plate is slidably installed in the support platform, the supporting base covers the swinging top plate, a first buffer device is provided on the support platform between the swinging top plate and the supporting base, the support platform is movably connected to the supporting base through a plurality of inclined supporting devices, and a second buffer device is installed between the inclined supporting device and the supporting base.

[0007] Through the above technical scheme, the vibration and impact of the steel structure are effectively reduced through the swing mechanism of the buffer device and the swing top plate, and the stable support of the steel structure is protected. The swing top plate adds a certain flexibility to the device, and can make corresponding adjustments according to the up and down vibrations of the steel structure, thereby reducing the amplitude and frequency of the steel structure vibration and dispersing the stress, ensuring the stability of the steel structure. The swing top plate can slide through the support platform, which effectively solves the problem of weak seismic resistance of the existing steel structure support in the horizontal direction.

[0008] Preferably, the swing top plate includes a top plate, a circular base and a swing table. A circular base is installed on the lower surface of the top plate. The circular base is slidably connected to the swing table. An arc groove matching the circular base is provided on the swing table. A buffer spring is provided between the top plate and the swing table.

[0009] Preferably, the circular base shaft is connected to the swing table, and a plurality of auxiliary rollers are installed in the arc groove.

[0010] Through the above technical scheme, the sliding connection between the circular base and the swing table and the design of the arc groove can make the swinging motion smoother. The installation of the auxiliary roller can effectively guide the movement of the circular base, reduce friction during the swinging process, and increase its service life. The buffer spring can slow down the contact between the top plate and the swing table, further increasing the smoothness of the movement and the buffering and shock absorption.

[0011] Preferably, a plurality of the oblique support devices are correspondingly installed on the lower surface of the support platform, and a slideway is provided on the support base.

[0012] Preferably, the oblique support device comprises a rotating shaft, an oblique support sliding column and a compression spring, the rotating shaft is connected to the compression spring via the oblique support sliding column, and the oblique support sliding column and the compression spring are movably installed in the slideway.

[0013] Preferably, limiting columns are installed on both sides of the support platform, and first buffer devices are abutted on both sides of the swing top plate.

[0014] Through the above technical scheme, the inclined support device and the second buffer device on the lower surface ensure the stability and balance of the platform during the process of descending and buffering and dispersing stress. The first buffer device abutting on both sides effectively prevents excessive movement of the swing top plate in the horizontal direction, and disperses the stress in the horizontal direction. The compression spring rebound inclined support slide column is combined with the second buffer device to support the support plate back to its original position to improve the durability and fatigue resistance of the system.

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. The utility model effectively reduces the vibration and impact of the steel structure through the swing mechanism of the buffer device and the swing top plate, protects the stable support of the steel structure, and the swing top plate adds a certain flexibility to the device, which can make corresponding adjustments according to the up and down vibrations of the steel structure, thereby reducing the amplitude and frequency of the steel structure vibration and dispersing the stress, ensuring the stability of the steel structure. The swing top plate can slide through the support platform, effectively solving the problem of weak seismic resistance of the existing steel structure support in the horizontal direction.

[0017] 2. The sliding connection between the circular base and the swing table and the design of the arc groove can make the swinging motion smoother. The installation of the auxiliary roller can effectively guide the movement of the circular base, reduce friction during the swinging process, and increase its service life. The buffer spring can slow down the contact between the top plate and the swing table, further increasing the smoothness of the movement and the buffering and shock absorption.

[0018] 3. The oblique support device and the second buffer device on the lower surface ensure the stability and balance of the platform during the process of descending and buffering the stress dispersion. The first buffer device abutting on both sides effectively prevents excessive horizontal movement of the swing top plate and disperses the stress in the horizontal direction. The compression spring rebound oblique support slide column is combined with the second buffer device to support the support plate back to its original position to improve the durability and fatigue resistance of the system.

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] A large-span steel structure support, such as Figure 1-4 As shown, it includes a support base 1, a swing top plate 2, a support platform 3, a first buffer device 41, a second buffer device 42 and a plurality of oblique support devices 6, the support base 1 is installed with the support platform 3, the swing top plate 2 is slidably installed in the support platform 3, the support base 1 covers the swing top plate 2, and a first buffer device 41 is provided on the support platform 3 between the swing top plate 2 and the support base 1, the support platform 3 is movably connected to the support base 1 through a plurality of oblique support devices 6, and a second buffer device 42 is installed between the oblique support device 6 and the support base 1, the first buffer device 41 and the second buffer device 42 are both damper jacket buffer springs 7 to reduce vibration and impact transmission, the swing top plate 2 can slide horizontally in the support platform 3, improve the freedom of the horizontal range of the swing top plate 2, cooperate with the first buffer device 41 installed on the side to disperse the concentrated force in the horizontal direction to absorb the impact, and the swing top plate 2 can swing under force The movement further assists shock absorption, and the support platform 3 is effectively supported by the oblique support device 6 and the second buffer device 42. When the steel structure shakes to buffer and release the force, the oblique support device 6 returns to the top, and limiting columns 5 are installed on both sides of the support platform 3. The first buffer device 41 on the upper surface of the support platform 3 is fixed to the support platform 3 at one end close to the supporting base 1, and the first buffer device 41 is abutted on both sides of the swing top plate 2, and the other end close to the swing top plate 2 is only abutted against the swing top plate 2, and moves with the squeezing of the swing top plate 21, which can effectively increase the service life of the first buffer device 41 and avoid the first buffer device 41 on the other side from being over-stretched when the swing top plate 2 moves horizontally to one side, thereby causing damage to the buffer spring 7. A through hole compatible with the limiting column 5 is opened on the support platform 3, and the limiting column 5 effectively prevents the support platform 3 from being dislocated during the swinging process, thereby ensuring the reliability and stability of the structure.

[0027] The swing top plate 2 includes a top plate 21, a circular base 22 and a swing platform 23. A circular base 22 is installed on the lower surface of the top plate 21, and the circular base 22 is slidably connected to the swing platform 23. An arc groove matched with the circular base 22 is opened on the swing platform 23. A buffer spring 7 is provided between the top plate 21 and the swing platform 23. The circular base 22 is axially connected to the swing platform 23. A number of auxiliary rollers are installed in the arc groove. The swing amplitude of the large-span steel structure itself is reduced by the swing of the circular base 22 in the arc groove of the swing platform 23 and the rebound of the buffer spring 7, and the vibration is weakened to provide effective support. The buffer spring 7 is installed in the mounting holes on the inclined surfaces at both ends of the swing platform 23, so that it can stably support the top plate 21. The auxiliary rod reduces the friction and resistance during swinging. The circular base 22 can rotate more smoothly and flexibly, so that the top plate 21 can swing smoothly.

[0028] A number of inclined support devices 6 are correspondingly installed on the lower surface of the support platform 3, and a slideway is opened on the support base 1, which cooperates with the second buffer device 42 on the lower surface of the support platform 3 to guide the movement of the inclined support device 6 to ensure its stable movement during the swinging process. The inclined support device 6 includes a rotating shaft 61, an inclined support slide column 62 and a compression spring 63. The rotating shaft 61 is connected to the compression spring 63 through the inclined support slide column 62. The inclined support slide column 62 and the compression spring 63 are movably installed in the slideway. There are two inclined support devices 6, which are relatively arranged to form a trapezoidal structure. When the swinging top plate 2 drives the support platform 3 to press down, the two inclined support devices 6 shrink inward to form a triangular state, providing auxiliary supporting force, improving the stability and seismic resistance of the entire structure, and lifting the support platform 3 through the rebound of the compression spring 63.

[0029] Working principle: First, assemble and fix the steel structure and the swing top plate 2. When the steel structure vibrates, the swing top plate 2 is forced to swing in sequence, and the pressure is transmitted through the swing top plate 2. The top plate 21 cooperates with the buffer spring 7 to perform the first shock absorption and buffering dispersion. The swing top plate 2 is further forced to slide on the support platform 3, and the first buffer devices 41 on both sides disperse the horizontal stress. The support platform 3 is forced to drop, and the oblique support device 6 is driven by the rotating shaft 61 thereof. The oblique support slide column 62 squeezes the compression spring 63 inward in the slideway of the support base 1. At this time, the compression spring 63 performs buffering and releases force, and cooperates with the second buffer device 42 on the lower surface of the support platform 3 to perform the final stress dispersion and shock absorption, thereby effectively dispersing the vertical stress and the horizontal stress, and completing the support of the steel structure.
