Description

Technical Field

[0001] This utility model relates to the field of seismic structure technology, and in particular to a self-resetting seismic support. Background Technology

[0002] The horizontal thrust at the supports of masonry structures is very large, so it is necessary to find a reasonable support type to adapt to the vibrations brought about by earthquakes and to ensure that the supports themselves return to their original positions after the earthquake.

[0003] According to the search, for example, the seismic isolation bearing provided by patent publication number CN219451139U includes an upper connecting plate, a rubber seat and a lower connecting plate. The rubber seat is fixedly connected to the bottom of the upper connecting plate, the lower connecting plate is fixedly connected to the bottom of the rubber seat, a reversing box is fixedly connected to the top of the lower connecting plate, a sliding plate is slidably connected to the top of the reversing box, support plates are fixedly connected to both sides of the sliding plate, a support plate is fixedly connected to one side of the support plate, and the two ends of the support plate are fixedly connected to the upper connecting plate and the lower connecting plate respectively. A buffer mechanism is slidably connected inside the sliding plate.

[0004] Based on the above search and combined with existing technology, it was found that existing seismic bearings similar to those disclosed above exhibit reduced reset performance after prolonged use or exposure to high-intensity vibrations. If they fail to reset for an extended period, the building poses a certain danger. Furthermore, it is difficult to detect the self-resetting status of existing seismic bearings. Therefore, a self-resetting seismic bearing is proposed to address these issues. Utility Model Content

[0005] The purpose of this application is to provide a self-resetting seismic bearing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a self-resetting seismic support, comprising a lower support, a seismic support column, and an upper support that are fixedly connected from bottom to top, wherein a signal generating device is installed at the lower end of the upper support and a signal reflecting device is installed at the upper end of the lower support;

[0007] The signal generating device includes a mounting base and a photoelectric sensor. The mounting base is fixed to the lower end of the upper support, and the photoelectric sensor is movably mounted on the lower end of the mounting base.

[0008] The signal reflection device includes a second mounting base and a reflector. The second mounting base is fixed to the upper end of the lower support, and the reflector is mounted on the upper end of the second mounting base.

[0009] In the initial state, the photoelectric sensor and the reflector are located on the same vertical line.

[0010] As a further supplement to this scheme, the seismic support includes multiple steel plates and multiple rubber pads, and the multiple steel plates and multiple rubber pads are stacked alternately, with the steel plates and rubber pads fixedly connected.

[0011] As a further supplement to this solution, the signal generating device also includes a spherical mounting block. The lower end of the mounting base is provided with a spherical groove. The spherical mounting block is movably mounted inside the spherical groove, and the photoelectric sensor is mounted on the part of the spherical mounting block located outside the spherical groove.

[0012] As a further supplement to this solution, the inner wall of the spherical groove is densely covered with grooves, and lubricating powder is placed in the grooves.

[0013] As a further supplement to this solution, the signal generating device also includes a transparent cover, which is placed on the outside of the mounting base, the photoelectric sensor and the spherical mounting block, and is fixedly connected to the lower end of the upper support.

[0014] As a further supplement to this solution, the lubricating powder is graphite powder.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. In this utility model, by setting the spherical mounting block, the photoelectric sensor is always in a vertically downward state under the action of the spherical mounting block, and the light signal emitted by it is always in a vertically downward state. Therefore, even if the lower support, the seismic support column and the upper support tilt synchronously and fail to reset, the photoelectric sensor and the reflector are misaligned at this time, and the reflected light signal cannot be received, thereby ensuring that a danger warning can be issued to the outside world.

[0017] 2. In this utility model, by densely distributing grooves on the inner wall of the spherical groove and placing lubricating powder in the grooves, the lubricating powder can lubricate the spherical mounting block, reducing the friction between the spherical mounting block and the inner wall of the spherical groove. This ensures that the spherical mounting block can smoothly rotate under the gravity of the photoelectric sensor until the photoelectric sensor is in a vertical position.

[0018] 3. In this utility model, by covering the outside of the mounting base, the photoelectric sensor and the spherical mounting block with a transparent cover, the interference caused by the external environment to the photoelectric sensor and the spherical mounting block can be reduced.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Reference Figure 1-2 The self-resetting seismic support shown includes a lower support 1, a seismic support column 3, and an upper support 2, which are fixedly connected from bottom to top. The seismic support column 3 includes multiple steel plates 31 and multiple rubber pads 32. The seismic support column 3 is formed by alternating stacking and vulcanizing of multiple steel plates 31 and multiple rubber pads 32, which can play a comprehensive seismic reset function.

[0027] A signal generating device 4 is installed at the lower end of the upper support 2, and a signal reflecting device 5 is installed at the upper end of the lower support 1. Specifically, the signal generating device 4 includes a mounting base 41 and a photoelectric sensor 42. The mounting base 41 is fixed to the lower end of the upper support 2, and the photoelectric sensor 42 is installed at the lower end of the mounting base 41. Specifically, an ML100 series photoelectric sensor 42 can be used. The signal reflecting device 5 includes a mounting base 51 and a reflector 52. The reflector 52 can be a conventional reflector plate. The mounting base 51 is fixed to the upper end of the lower support 1, and the reflector 52 is installed at the upper end of the mounting base 51. In the initial state, the photoelectric sensor 42 and the reflector 52 are located on the same vertical line.

[0028] Under normal conditions, the light signal from the photoelectric sensor 42 can be reflected back to the photoelectric sensor 42 through the reflector 52. However, when the service life is long or the earthquake-resistant support 3 fails to return to its original position after a major earthquake, the photoelectric sensor 42 and the reflector 52 are misaligned and cannot receive the reflected light signal. In this case, the light signal can be processed by the existing conventional controller and then transmitted to the external monitoring background in a timely manner through the wireless signal transmitter to improve safety.

[0029] Example 2: Considering the simultaneous tilting of the lower support 1, seismic support column 3, and upper support 2, and their failure to return to their original positions, compared with Example 1, as follows... Figure 3 As shown, the signal generating device 4 in this embodiment also includes a spherical mounting block 43. The lower end of the mounting base 41 is provided with a spherical groove. The spherical mounting block 43 is movably mounted on the inner side of the spherical groove. The photoelectric sensor 42 is mounted on the part of the spherical mounting block 43 located on the outer side of the spherical groove.

[0030] Under the action of the spherical mounting block 43, the photoelectric sensor 42 is always in a vertically downward state, and the light signal it emits is also always in a vertically downward state. Therefore, when the lower support 1, the seismic support column 3 and the upper support 2 tilt synchronously and fail to return to their original positions, the photoelectric sensor 42 and the reflector 52 are misaligned and cannot receive the reflected light signal, thus ensuring that a danger warning can be issued to the outside world.

[0031] The inner wall of the spherical groove is densely covered with grooves (not shown in the figure), and lubricating powder (not shown in the figure) is placed in the grooves. Specifically, the lubricating powder is graphite powder. The lubricating powder can lubricate the spherical mounting block 43, reduce the friction between the spherical mounting block 43 and the inner wall of the spherical groove, and ensure that the spherical mounting block 43 can rotate smoothly under the gravity of the photoelectric sensor 42 until the photoelectric sensor 42 is in a vertical state.

[0032] Example 3: Compared to Example 1 and Example 2 above, as... Figure 4 As shown, the signal generating device 4 also includes a transparent cover 44, which covers the outside of the mounting base 41, the photoelectric sensor 42 and the spherical mounting block 43. The transparent cover 44 is fixedly connected to the lower end of the upper support 2. The transparent cover 44 can reduce the interference caused by the external environment to the photoelectric sensor 42 and the spherical mounting block 43.

[0033] It should be noted that the specific model and specifications of the controller and any other electrical equipment involved in this solution need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. The power supply and principle of the controller and any other electrical equipment involved are clear to those skilled in the art, and will not be described in detail here.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
