Description

TECHNICAL FIELD

[0001] The present application relates to the field of shock isolation placement, and particularly relates to a rolling swing support. BACKGROUND

[0002] When the earthquake energy is large, the existing shock isolation support needs to provide a large enough starting external force to lift and press the locking element into the installation cavity of the middle seat plate, so that the lower spherical surface friction pair produces relative swing, and the support starts to play the function of shock reduction and isolation. Through the friction between the spherical surface friction pairs, the earthquake energy is consumed, and at the same time, the upper seat plate swings on the double curved surface relative to the lower seat plate, the propagation path of the earthquake wave is prolonged, and the transmission of the earthquake energy to the upper structure is reduced. And after the earthquake energy is reduced to a certain extent, the support is reset in a forced vibration state, so as to realize that the support returns to the initial equilibrium position. Therefore, the rolling swing support is provided to avoid the problem that the shock isolation support is inconvenient to reset quickly in actual use. SUMMARY

[0003] The present application aims to provide a rolling swing support, which solves the problem that the shock isolation support needs to wait for the earthquake energy to reduce to a certain extent to realize the reset of the shock isolation support.

[0005] Preferably, the top end and the bottom end of the spherical cap lining plate are provided with a plurality of arc-shaped grooves, and a plurality of rolling balls are respectively installed in the interiors of the arc-shaped grooves.

[0006] Preferably, the top end and the bottom end of the spherical cap lining plate are provided with a plurality of threaded holes, one end of the upper rolling ball positioning plate and the lower rolling ball positioning plate is provided with a countersunk hole corresponding to the position of the threaded hole one by one, and a connecting bolt is installed between the countersunk hole and the threaded hole.

[0007] Preferably, the ends close to each other of the upper rolling curved surface plate and the lower rolling curved surface plate are fixedly installed with a limiting buckle.

[0008] Compared with the prior art, the present application has the following beneficial effects: The rolling swing support is connected into a rolling whole through the ball crown lining plate, the upper ball positioning plate and the lower ball positioning plate, which can effectively prolong the structural period, isolate the earthquake effect, and realize self-resetting.

[0013] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0014] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention 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, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0015] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] This invention provides a rolling pendulum support, including an upper rolling curved plate 1, balls 2, an upper ball positioning plate 3, a spherical crown liner 4, a lower ball positioning plate 6, and a lower rolling curved plate 7. The two ends of the spherical crown liner 4 are respectively bolted to the upper ball positioning plate 3 and the lower ball positioning plate 6. Balls 2 are installed between the adjacent ends of the upper ball positioning plate 3 and the lower ball positioning plate 6 and the two ends of the spherical crown liner 4. The balls 2, upper ball positioning plate 3, and lower ball positioning plate 6 are bolted together at the two ends of the spherical crown liner 4, effectively connecting them into a rolling pendulum assembly. This effectively extends the structural period, isolates seismic forces, and enables self-resetting. Gaps are left between the upper ball positioning plate 3, the lower ball positioning plate 6, the upper rolling curved plate 1, and the lower rolling curved plate 7 to ensure that the balls 2 roll without mechanical obstruction. The rolling of the balls 2 causes the spherical crown liner 4 to move between the two rolling curved plates, improving the seismic isolation effect and achieving the self-resetting effect of the two rolling curved plates and the spherical crown liner 4.

[0017] It should also be noted that the top and bottom of the spherical crown liner 4 are provided with multiple arc-shaped grooves 8, and multiple balls 2 are respectively installed inside the multiple arc-shaped grooves 8. Both ends of the rolling curved panel and both ends of the spherical crown liner 4 are provided with arc-shaped grooves 8 that match the shape and size of the balls 2. The balls 2 are installed in the arc-shaped grooves 8. Both the top and bottom of the spherical crown liner 4 are provided with several threaded holes. One end of the upper ball positioning plate 3 and the lower ball positioning plate 6 is provided with countersunk screw holes that correspond one by one to the positions of the threaded holes. Connecting bolts are installed between the countersunk screw holes and the threaded holes. The upper ball positioning plate 3, the lower ball positioning plate 6 and the spherical crown liner 4 are connected by connecting bolts screwed into the threaded holes and countersunk screw holes, which can reduce the thickness of the upper ball positioning plate 3 and the lower ball positioning plate 6 to a greater extent and is also convenient for replacement. Limit buckles 5 are fixedly installed at the close ends of the upper rolling curved panel 1 and the lower rolling curved panel 7, which effectively prevents the rolling whole from falling out of position when the structure has a large displacement. In practical use, this device can be used by simultaneously connecting the ball bearings 2, upper ball bearing positioning plate 3, and lower ball bearing positioning plate 6 on both sides of the spherical crown liner 4. When used alone, the upper rolling curved panel 1, a single ball bearing 2, and upper ball bearing positioning plate 3 work together to achieve a reciprocating oscillating vibration isolation effect through the rolling of the ball bearings. This is the installation of a single rolling curved panel. In practical use, this rolling pendulum support, after installing two rolling curved panels in their respective positions, and with the ball bearings 2, upper ball bearing positioning plate 3, and lower ball bearing positioning plate 6 bolted to both ends of the spherical crown liner 4, effectively connects them into a rolling whole, effectively extending the structural period, isolating seismic forces, and achieving self-resetting. A gap is left between the upper ball bearing positioning plate 3, lower ball bearing positioning plate 6, upper rolling curved panel 1, and lower rolling curved panel 7. The gap ensures that there is no mechanical obstruction when the ball 2 rolls. The rolling of the ball 2 drives the spherical crown liner 4 to move between the two rolling curved panels, improving the earthquake isolation effect and achieving the self-resetting effect of the two rolling curved panels and the spherical crown liner 4. The two ends of the rolling curved panels and the two ends of the spherical crown liner 4 are provided with arc-shaped grooves 8 that match the shape and size of the ball 2. The ball 2 is installed in the arc-shaped grooves 8. The upper ball positioning plate 3, the lower ball positioning plate 6 and the spherical crown liner 4 are connected by connecting bolts screwed into threaded holes and countersunk screw holes, which can reduce the thickness of the upper ball positioning plate 3 and the lower ball positioning plate 6 to a greater extent and facilitate replacement. Limit buckles 5 are fixedly installed at one end of the upper rolling curved panel 1 and the lower rolling curved panel 7 respectively, effectively preventing the rolling whole from falling out of position when the structure undergoes large displacement.

[0018] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
