Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure support technology, and in particular to steel structure supports with good seismic performance. Background Technology
[0002] The steel structure support has cutting edges on both the end face perpendicular to the tool holder and the outer circle, primarily used for milling flat surfaces. The cutting edge on the outer circle is the main cutting edge, while the cutting edge on the end face functions similarly to a scraper. Compared to a sleeve-type end mill, the steel structure support has a shorter cutting edge.
[0003] In the existing technology, in order to ensure the stability of the steel structure support during the use of the steel structure support, it is necessary to add a seismic structure for vibration reduction. However, if the steel structure support is affected by vibration and torsional displacement occurs, it will cause tension and pull on the connected seismic structure. This will not only damage the seismic structure and affect its service life, but also affect the vibration reduction effect and the stability of the steel structure support. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the prior art that when steel structure supports are used, the torsional displacement caused by vibration will cause tension and pull on the connected seismic-resistant structure, which will not only damage the seismic-resistant structure and affect its service life, but also affect the shock absorption effect and the stability of the steel structure support. The invention proposes a steel structure support with good seismic performance.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A steel structure support with good seismic performance includes a base and a connecting ring. The connecting ring is fixedly connected to the side wall of the base. A steel structure connecting plate is provided above the base. Multiple connecting cylinders are hinged around the inner wall of the base. Multiple connecting rods are fixedly connected around the bottom of the steel structure connecting plate. Shock-absorbing springs are provided inside the connecting cylinders. A connecting plate is fixedly connected to the bottom of the steel structure connecting plate. Multiple limiting rods are fixedly connected around the bottom of the connecting plate. A support column is provided below the steel structure connecting plate. A slot is opened on the inner wall of the top of the support column. The limiting rods extend into the inside of the slot.
[0007] Preferably, a piston is fixedly connected to one end of the connecting rod located inside the connecting cylinder, and the piston is pressed against the end of the shock-absorbing spring.
[0008] Preferably, a damping ring is fixedly connected to the inner wall of the top end of the connecting cylinder, and the rod wall of the connecting rod is fitted into the inner wall of the damping ring.
[0009] Preferably, the bottom inner wall of the base is surrounded and fixedly connected with multiple connecting strips, and a connecting platform is fixedly connected to the center of the multiple connecting strips at the same time. The bottom of the support column is fixedly connected to the inside of the connecting platform.
[0010] Preferably, the inner wall of the top of the support column is rounded, and the wall of the limiting rod is set as an arc-shaped rod.
[0011] Preferably, the inner wall of the steel structure connecting plate at the center has multiple rectangular openings.
[0012] Compared with the prior art, this utility model provides a steel structure support with good seismic performance, and has the following beneficial effects:
[0013] 1. This steel structure support with good seismic performance can stably connect the structural components to be supported to the steel structure support through the steel structure connecting plate. When subjected to vibration, the connecting rod slides along the inner wall of the connecting cylinder through the piston, which can compress the damping spring to absorb energy, reduce the transmission of vibration, and improve the damping effect. The sliding of the connecting rod on the inner wall of the damping ring can further absorb energy and improve stability.
[0014] 2. This steel structure support with good seismic performance can provide a certain degree of support and anti-torsion effect by having the limiting rod slide along the groove on the inner wall of the top of the support column when shaking. This reduces the impact of torsional force on the hinge point of the connecting rod and the connecting cylinder, thus preventing wear and tear that could affect the service life, and further ensures the seismic performance.
[0015] 3. This steel structure support with good seismic performance can ensure a stable connection to the support column through connecting strips and connecting platforms, while the limit rod is set as an arc rod to improve stability and does not affect the use when the steel structure connecting plate and the base swing relative to each other.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-4 The steel structure support with good seismic performance includes a base 1 and a connecting ring 2. The connecting ring 2 is fixedly connected to the side wall of the base 1. A steel structure connecting plate 3 is provided above the base 1. The inner wall of the steel structure connecting plate 3 at the center has multiple rectangular openings. Multiple connecting cylinders 4 are hinged around the inner wall of the base 1. Multiple connecting rods 5 are fixedly connected around the bottom of the steel structure connecting plate 3. The connecting cylinders 4 are equipped with shock-absorbing springs 7. A connecting plate 12 is fixedly connected to the bottom of the steel structure connecting plate 3. Multiple limiting rods 13 are fixedly connected around the bottom of the connecting plate 12. A support column 11 is provided below the steel structure connecting plate 3. A slot is provided on the inner wall of the top of the support column 11. The limiting rods 13 extend into the slot.
[0023] A piston 6 is fixedly connected to one end of the connecting rod 5 inside the connecting cylinder 4. The piston 6 is pressed against the end of the shock-absorbing spring 7. A damping ring 8 is fixedly connected to the inner wall of the top of the connecting cylinder 4. The rod wall of the connecting rod 5 is fitted against the inner wall of the damping ring 8.
[0024] In use, the steel structure connecting plate 3 can stably connect the structural component to be supported to the steel structure bracket. When subjected to vibration, the connecting rod 5 slides along the inner wall of the connecting cylinder 4 through the piston 6, which can compress the damping spring 7 to absorb energy, reduce the transmission of vibration, and improve the damping effect. The sliding of the connecting rod 5 on the inner wall of the damping ring 8 can further absorb energy and improve stability.
[0025] During the vibration reduction process, the steel structure connecting plate 3 and the base 1 will sway relative to each other. In order to reduce the torque generated during the swaying and cause the steel structure connecting plate 3 and the base 1 to rotate relative to each other, the limiting rod 13 will slide along the groove on the inner wall of the top of the support column 11 during the swaying. This can play a certain supporting and anti-torsion role, reduce the impact of torsional force on the hinge point of the connecting rod 5 and the connecting cylinder 4, which would lead to wear and affect the service life, and at the same time further ensure the seismic effect.
[0026] To improve stability, such as Figure 1-4As shown, multiple connecting strips 9 are fixedly connected around the bottom inner wall of the base 1, and a connecting platform 10 is fixedly connected at the center of the multiple connecting strips 9. The bottom of the support column 11 is fixedly connected to the inside of the connecting platform 10, and the top inner wall of the support column 11 is rounded. The rod wall of the limiting rod 13 is set as an arc rod.
[0027] The connecting strip 9 and the connecting platform 10 can ensure a stable connection to the support column 11, while the limit rod 13 is set as an arc rod 13 to improve stability and does not affect the use when the steel structure connecting plate 3 and the base 1 swing relative to each other.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
