[0002] An aseismic bearing refers to a support device provided to meet the requirements of seismic isolation. An isolation layer is added between the superstructure and the foundation, and a rubber seismic isolation bearing is installed to achieve a soft connection with the ground. Through such technology, about 80% of the earthquake energy can be offset. It is a structural member with relatively small horizontal stiffness and relatively large vertical stiffness, which can withstand large horizontal deformations and can be used as part of the load-bearing system. During the installation process of the aseismic bearing, a hoisting device is usually required to lift the aseismic bearing. During the process of lowering the aseismic bearing, the installer adjusts the angle of the aseismic bearing by hand so that the installation holes at the lower end of the aseismic bearing are aligned with the reserved holes on the installation foundation for subsequent accurate installation.

[0003] In the prior art, the positioning accuracy is poor by manual positioning, and multiple adjustments are required to fully meet the installation requirements, resulting in low installation efficiency. Therefore, a positioning device for aseismic bearing installation is needed. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in 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. 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.

[0022] Embodiment: Refer to Figures 1-3 A positioning device for the installation of a seismic isolation bearing shown, including a guiding and positioning hopper installed on the installation foundation. The guiding and positioning hopper includes:

[0023] A guiding hopper, which is a trapezoidal funnel with a square cross-section. The upper port diameter of the guiding hopper is larger than the lower port diameter of the guiding hopper, and the shape and size of the inner side of the lower end of the guiding hopper are the same as the shape and size of the lower installation plate of the seismic isolation bearing;

[0024] A positioning hopper, which is located at the lower end of the guiding hopper and is fixed to the lower end of the guiding hopper. The positioning hopper is a straight hopper with a square cross-section, and the shape and size of the inner side of the positioning hopper are also the same as the shape and size of the lower installation plate of the seismic isolation bearing.

[0025] Based on the above structure, when using a lifting device to lift and then lower the seismic isolation bearing, the staff only needs to hold the seismic isolation bearing by hand, assist the seismic isolation bearing to turn, and make the installation plate at the lower end of the seismic isolation bearing automatically adjust its own angle under the guiding action of the guiding hopper. Finally, the installation holes on the lower installation plate of the seismic isolation bearing are aligned with the reserved holes on the installation foundation during the lowering process. After the lowering is completed, the seismic isolation bearing is located above the installation foundation, and the installation plate at the lower end of the seismic isolation bearing is located in the positioning hopper, forming a completely aligned state. This is beneficial to complete the positioning and installation operation of the seismic isolation bearing in a single operation, and the standardized guiding hopper and positioning hopper have high positioning accuracy and do not require multiple adjustments, thus significantly improving the positioning accuracy and installation efficiency during installation.

[0026] Furthermore, the guiding hopper and the positioning hopper are jointly composed of two semi-hoppers 1 arranged symmetrically and two mounting limit frames 4 arranged symmetrically. The lower end of the semi-hopper 1 is integrally formed with the upper end of the mounting limit frame 4. Connecting ears 2 are integrally formed on the outer side walls of both the semi-hopper 1 and the mounting limit frame 4. The connecting ears 2 on the two semi-hoppers 1 and the connecting ears 2 on the two mounting limit frames 4 are fixedly connected by connecting bolts 3;

[0027] By setting the guiding hopper and the positioning hopper as two detachable semi-hopper bodies, namely the semi-hopper 1 and the limit frame 4, the positioning device for the aseismic support installation can be quickly installed through the connecting bolts 3 and the connecting ears 2 during use, which is convenient for assembly. After use, the semi-hopper 1 and the limit frame 4 can be disassembled by unscrewing the connecting bolts 3, facilitating the installation and disassembly operations of the positioning device for the aseismic support installation. It is convenient to use and can be reused.

[0028] Furthermore, movable balls 5 are rollingly embedded inside the semi-hopper 1. A plurality of movable balls 5 are provided and evenly distributed along the inner side wall of the semi-hopper 1. Through the setting of the movable balls 5, when the aseismic support contacts the inner side of the semi-hopper 1, it can automatically turn under the rolling action of the movable balls 5 and its own gravity, so that the aseismic support can perform semi-automatic adjustment and positioning during the descending process. Compared with the method of completely manually pushing for positioning, the semi-automatic adjustment and positioning method can reduce the workload of the staff and is more conducive to quickly positioning the aseismic support.

[0029] Furthermore, anti-slip inclined lines 6 are provided on the inner side wall of the mounting limit frame 4. A plurality of anti-slip inclined lines 6 are provided and evenly distributed on the plurality of inner side walls of the mounting limit frame 4;

[0030] On the same inner side wall of the mounting limit frame 4, the plurality of anti-slip inclined lines 6 are divided into two groups. The two groups of anti-slip inclined lines 6 are symmetrically arranged along the central axis of this side wall of the mounting limit frame 4, and the inclination directions of the two groups of anti-slip inclined lines 6 are opposite;

[0031] Through the setting of the anti-slip inclined lines 6, the connection between the mounting limit frame 4 and the installation foundation can be made more stable. At the same time, by setting two groups of opposite anti-slip inclined lines 6, the stable effect provided by the anti-slip inclined lines 6 can be further improved, making the connection stability between the mounting limit frame 4 and the installation foundation better.

[0032] Furthermore, stable convex ribs 7 are fixed at both the upper and lower ends of the inner side wall of the mounting limit frame 4. The two stable convex ribs 7 are respectively located at the upper and lower ends of the anti-slip inclined lines 6, and the stable convex ribs 7 are in interference fit with the installation foundation;

[0033] Through the setting of the stable convex rib 7, an interference fit is formed between the inner side of the installation limit frame 4 and the installation foundation, thereby further improving the connection stability between the installation limit frame 4 and the installation foundation, and thus enhancing the stability of the positioning device for the installation of the seismic isolation bearing during use.

[0034] The working principle of the present utility model: During daily use, by placing the two semiconductor hoppers 1 and the two installation limit frames 4 on both sides of the installation foundation, and making the two semiconductor hoppers 1 and the two installation limit frames 4 arranged oppositely, and then passing the connecting bolts 3 through the connecting ears 2 and tightening them, so that the two semiconductor hoppers 1 and the two installation limit frames 4 form a guiding hopper and a positioning hopper that embrace the installation foundation. During the process of lowering the seismic isolation bearing by the hoisting equipment, the installation plate at the lower end of the seismic isolation bearing first comes into active contact with the movable ball 5, and deflects under the guiding action of the movable ball 5 and its own gravity. Finally, the installation holes on the installation plate at the lower end of the seismic isolation bearing are aligned with the reserved holes on the installation foundation during the lowering process. After the lowering is completed, the seismic isolation bearing is located above the installation foundation, and the installation plate at the lower end of the seismic isolation bearing is located within the positioning hopper, forming a completely aligned state. This is conducive to completing the positioning and installation operation of the seismic isolation bearing in a single operation, and the positioning accuracy of the standard guiding hopper and positioning hopper is relatively high, without the need for multiple adjustments, thus significantly improving the positioning accuracy and installation efficiency during installation. During the installation process, the staff can also assist in the steering adjustment of the seismic isolation bearing by means of hand pushing, so that the positioning of the seismic isolation bearing is faster.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
