[0025] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0026] As shown in Figs. 1-2 The present application provides a self-resetting seismic reduction ball-type support, which comprises an upper support assembly, a lower support assembly and a vibration reduction spring 13, the vibration reduction spring 13 is arranged in the east, west, south and north four directions of the basin ring wall of the upper support assembly and the lower support assembly respectively, and abuts against the basin ring wall.

[0027] This invention employs vibration damping springs 13 arranged in the east, west, south, and north directions on the ring walls of the upper and lower support assemblies. This simplifies the structure and reduces the number and complexity of components. When a vehicle passes by or the support is subjected to other external forces, the vibration damping springs 13 can effectively absorb and reduce the resulting vibrations and stresses, thereby protecting the support and the structure it supports from damage. Moreover, the elasticity and restoring force of the vibration damping springs 13 allow the upper and lower support assemblies to quickly and stably return to their original positions after being subjected to external forces, thus maintaining the overall stability and reliability of the support.

[0028] As an optional implementation, such as Figs. 1-2 As shown, the upper support assembly includes an upper support base plate 1, an upper support stainless steel sliding plate 2, an upper support PTFE plate sliding plate 3, an upper support pressure bearing member 4, and an upper support ball core 5, which are connected sequentially from top to bottom; the upper support PTFE plate sliding plate 3 is embedded on the top surface of the upper support pressure bearing member 4 and is slidably connected to the upper support stainless steel sliding plate 2 along at least one preset direction.

[0029] Furthermore, the upper support base plate 1 is connected to the upper structure it supports.

[0030] The upper support PTFE plate slide plate 3 and the upper support stainless steel slide plate 2 are slidably connected in at least one preset direction. This arrangement allows the upper structure to transmit displacement and absorb energy in the predetermined direction when subjected to horizontal force. During this process, the upper support PTFE plate slide plate 3 and the upper support stainless steel slide plate 2 slide relative to each other, dispersing and absorbing energy through sliding friction, thus protecting the upper structure from damage.

[0031] As an optional implementation, such as Figs. 1-2 As shown, the top surface of the upper support ball core 5 is a spherical surface, and the bottom surface of the upper support bearing member 4 is an upper curved ball socket 41 that matches the top surface of the upper support ball core 5.

[0032] Through the rotational engagement between the spherical surface of the upper support ball core 5 and the upper curved ball socket 41 of the upper support bearing member 4, the energy transmitted from the upper structure can be absorbed and dispersed, protecting the upper structure from damage.

[0033] As an optional implementation, such as Figs. 1-2 As shown, the lower support assembly includes a lower support base plate 7, a lower support stainless steel sliding plate 8, a lower support PTFE plate sliding plate 9, a lower support pressure bearing member 10, and a lower support ball core 11 connected sequentially from bottom to top; the lower support PTFE plate sliding plate 9 is embedded in the bottom surface of the lower support pressure bearing member 10 and is slidably connected to the lower support stainless steel sliding plate 8 along at least one preset direction.

[0034] Furthermore, the lower support base plate 7 is connected to the lower structure it supports.

[0035] The lower support four-fluorine plate sliding plate 9 and the lower support stainless steel sliding plate 8 are slidably connected in at least one preset direction, so that the lower structure can transmit displacement and absorb energy in the predetermined direction when subjected to horizontal force, and relative sliding occurs between the lower support four-fluorine plate sliding plate 9 and the lower support stainless steel sliding plate 8 in the process, thereby dispersing and absorbing energy through sliding friction and protecting the lower structure from damage.

[0036] As an optional implementation, as shown in Figs. 1-2 The bottom surface of the lower support ball core 11 is a spherical surface, and the top surface of the lower support pressure-bearing piece 10 is a lower curved surface ball socket 101 matched with the bottom surface of the lower support ball core 11.

[0037] Through the rotational fit between the spherical surface of the lower support ball core 11 and the lower curved surface ball socket 101 of the lower support pressure-bearing piece 10, the energy transmitted from the lower structure can be absorbed and dispersed, and the lower structure is protected from damage.

[0038] As an optional implementation, as shown in Figs. 1-2 The non-spherical surface of the lower support ball core 11 is provided with a groove 111 for reciprocating movement of the upper support ball core 5, and the groove 111 is provided with a lower accommodating groove 112. The non-spherical surface of the upper support ball core 5 is provided with an upper accommodating groove 51, and the upper accommodating groove 51 and the lower accommodating groove 112 jointly form an installation space for installing the mounting block 14.

[0039] Further, the mounting block 14 is inserted into the lower accommodating groove 112 and the upper accommodating groove 51 to stabilize the relative position between the upper support ball core 5 and the lower support ball core 11.

[0040] When a certain range of earthquakes is encountered, the earthquake force will act on the support, causing the upper support ball core 5 to move in the groove 111, causing a certain degree of misalignment between the upper support ball core 5 and the lower support ball core 11, absorbing and dispersing earthquake energy. When the earthquake intensity exceeds the preset bearing range, the misalignment will cause the safety block to be damaged, prompting relevant personnel to maintain in time.

[0041] As an optional implementation, as shown in Figs. 1-2 The upper support base plate 1 and the lower support base plate 7 are each provided with a mounting column, and the mounting column is provided with a mounting groove for mounting the vibration isolation spring 13; the mounting groove is provided through the mounting column in the horizontal direction, and the vibration isolation spring 13 abuts against the basin ring wall of the upper support pressure-bearing piece 4 or the lower support pressure-bearing piece 10.

[0042] Further, the upper support base plate 1 is provided with an upper mounting column 6, and the upper mounting column 6 is provided with an upper mounting groove 61 for mounting the vibration isolation spring 13.

[0043] The upper mounting column 6 is arranged on the corresponding east, west, south and north direction of the basin ring wall of the upper support pressure component 4, so that the vibration isolation spring 13 can be horizontally placed in the upper mounting slot 61 and effectively abut with the basin ring wall of the upper support pressure component 4.

[0044] The lower mounting column 12 is arranged on the lower support base plate 7, and the lower mounting slot 121 is arranged on the lower mounting column 12, which is used for mounting the vibration isolation spring 13.

[0045] The lower mounting column 12 is arranged on the corresponding east, west, south and north direction of the basin ring wall of the lower support pressure component 10, so that the vibration isolation spring 13 can be horizontally placed in the lower mounting slot 121 and effectively abut with the basin ring wall of the lower support pressure component 10.

[0046] As an optional embodiment, the mounting slot is provided with a threaded section at one end away from the upper support pressure component 4 or the lower support pressure component 10, which is used for adjusting the compression degree of the vibration isolation spring 13 through a bolt.

[0047] Further, the upper mounting slot 61 is provided with a threaded section at one end away from the upper support pressure component 4.

[0048] The lower mounting slot 121 is provided with a threaded section at one end away from the lower support pressure component 10.

[0049] The bolt is screwed with the threaded section of the upper mounting slot 61 or the lower mounting slot 121. After the bolt is screwed into the threaded section, the compression degree of the vibration isolation spring 13 is adjusted by rotating the bolt according to the use requirement, which is convenient to operate and has good flexibility and adaptability. Specifically, when it is needed to increase the compression degree of the vibration isolation spring 13, the vibration isolation spring 13 can be moved towards the upper support pressure component 4 or the lower support pressure component 10 by rotating the bolt, so as to increase the compression amount of the vibration isolation spring 13. Conversely, when it is needed to reduce the compression degree of the vibration isolation spring 13, the bolt can be rotated reversely, so as to reduce the compression amount of the vibration isolation spring 13 and relax the vibration isolation spring 13.
