Description

Technical Field

[0001] The present invention relates to the technical field of test and detection devices, and particularly relates to a performance detection device for rubber isolation bearings. Background Art

[0002] In modern equipment supports, building and other engineering structures, the performance of rubber isolation bearings has an important impact on the stability of the superstructure; currently, rubber isolation bearings generally consist of a multi-layer structure formed by alternating thin steel plates and thin rubber plates, and are vulcanized at high temperature and high pressure. They can stably support the upper structure, so that under the action of dynamic loads such as earthquakes, the horizontal stiffness can be greatly reduced, effectively blocking the transmission of seismic energy to the upper structure, significantly improving the seismic performance of buildings, and ensuring life and property safety.

[0003] However, there are many problems in the current detection work for the performance of rubber isolation bearings; on the one hand, the existing detection devices have relatively single functions and often can only detect one or a few performance indicators of rubber isolation bearings; for example, they can only detect the vertical bearing capacity and cannot take into account the testing of key performance parameters such as lateral deformation under dynamic load; this will result in the need to frequently replace different detection devices when evaluating the comprehensive performance of rubber isolation bearings, not only consuming a large amount of time and labor costs, but also easily affecting the accuracy and reliability of the detection results due to the errors brought by equipment switching, and is not conducive to judging whether the lateral deformation of the rubber isolation bearing under the design pressure is within the qualified range.

[0004] In summary, regarding the performance of rubber isolation bearings, it is necessary to detect their lateral deformation states under different bearing pressure states to achieve the comprehensive performance detection of rubber isolation bearings; in view of this, we propose a performance detection device for rubber isolation bearings.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1-6 , the present invention details the above technical solutions through the following embodiments:

[0037] A performance detection device for a rubber isolation bearing, including a vibration motor 9 for providing a detection vibration force. The vibration motor 9 is installed at the bottom of the horizontal base 4. It should be noted that the detection principle of this device is to compare the deformation displacement distances before and after installing the rubber isolation bearing specimen 82, so as to judge the isolation performance of the rubber isolation bearing specimen 82 under the same conditions. It also includes:

[0038] The isolation installation part 8. Since the isolation performance of the rubber isolation bearing specimen 82 needs to consider the pressure condition, in this embodiment, the isolation installation part 8 includes a support plate 81 provided with a card slot 811. The rubber isolation bearing specimen 82 is placed in the card slot 811, and above it is as Figure 6 shown in the structure. A first card seat 83 is detachably installed on the rubber isolation bearing specimen 82. A second card seat 84 is detachably installed above the first card seat 83 through a fastening screw 85. A pressure counterweight 86 is detachably installed between the first card seat 83 and the second card seat 84. Counterweights with the same diameter can be selected according to different pressures, and the fastening screw 85 is adjusted to make the second card seat 84 press the pressure counterweight 86.

[0039] In order to obtain a deformation space under vibration conditions, four vibration displacement units 7 are installed at the four corners of the horizontal base 4 through connecting frames 6. The vibration displacement unit 7 includes a support block 71 provided with a support groove 711. The support plate 81 is installed between the four support grooves 711.

[0040] As Figures 3-5 shown in the structure, a support plate 72 is connected to the outside of the support block 71. The support plate 72 is movably installed on a positioning plate 73 provided with a horizontal movement groove 731. In order to obtain a movement space, a threaded rod 74 is threadedly installed on the support plate 72. Both ends of the threaded rod 74 are threadedly installed with sleeve blocks 76 in a spherical structure as Figure 4 shown. A spring 75 is sleeved on the threaded rod 74 between the sleeve block 76 and the support plate 72. In order to facilitate the forward and backward movement in the horizontal direction, the positioning plate 73 is as Figure 5 shown in the structure, provided with a horizontal rod groove 733 for inserting and moving the threaded rod 74, and an embedded groove 734 for limiting the movement of the sleeve block 76. The spherical sleeve block 76 is used to reduce the contact area and reduce friction, facilitating movement.

[0041] In this embodiment, for the convenience of installation, as Figure 4 shown in the structure, a first jack 721 is provided on the support plate 72, and a second jack 732 is provided on the positioning plate 73. A pin 77 is inserted between the first jack 721 and the second jack 732, which can be fixed when installing the isolation installation part 8, and the pin 77 needs to be pulled out during detection.

[0042] In this embodiment, infrared ranging sensors are detachably installed on the four mounting seats 2, which can detect the real-time distance fluctuations of each sensor during vibration, so as to judge the lateral displacement distance of the pressure counterweight 86 and evaluate the performance of the rubber isolation bearing specimen 82 under specific pressure conditions.

[0043] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0045] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
