[0002] The converter valve tower is generally suspended on the steel beam of the steel structure. The steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. When the steel structure is in use, it is often necessary to consider the influence of vibration on the steel structure and to carry out shock absorption and reinforcement on the steel structure.

Through the engagement of the external thread 4 of the connecting member and the internal thread 9 of the sleeve, the connection between the first connecting member 3 and the sleeve 5 is realized, which is convenient for installation and disassembly during construction, maintenance and other processes, and has high flexibility.

[0034] As Figure 1 、 Figure 3 、 Figure 4 and Figure 5 shown, a plurality of connecting rods 15 are provided on the inner side wall of the sleeve 5, and a multi-lobe sector frustum 13 is provided on the connecting rod 15; on the connecting rod 15, a first spring 16 is provided between the multi-lobe sector frustum 13 and the inner side wall of the sleeve 5; the suspension rod 6 is provided on the multi-lobe sector frustum 13.

[0035] Specifically, a multi-lobe sector frustum 13 is provided on the inner side wall of the sleeve 5 through a plurality of connecting rods 15, and a first spring 16 is provided between the multi-lobe sector frustum 13 and the inner side wall of the sleeve 5. The suspension rod 6 for connecting the converter valve tower is provided on the multi-lobe sector frustum 13. When a relative displacement or relative position trend occurs between the converter valve tower and the steel beam 1, the damping effect can be achieved by compressing the first spring 16, and problems such as deformation of the steel structure are solved.

[0036] Optionally, a plurality of second connecting holes 11 are provided on the inner wall of the sleeve 5; the multi-lobe sector frustum 13 includes a plurality of sector block structures, and a third connecting hole 14 is provided on each sector block structure; both ends of the connecting rod 15 are respectively sleeved in the second connecting hole 11 and the third connecting hole 13. A limiting frustum 18 is provided at one end of the connecting rod 15 close to the second connecting hole 11, and a rubber pad 17 is provided at one end close to the third connecting hole 14. The first spring 16 is located between the limiting frustum 18 and the rubber pad 17.

[0039] Specifically, when a converter valve tower is provided on the suspension rod 6, under the action of the gravity of the converter valve tower, the slider 19 slides in the middle hole on the multi-lobe sector frustum 13, squeezing the multiple sector blocks outwards, and the middle hole on the multi-lobe sector frustum 13 becomes larger, thereby compressing the first spring 16, and further causing the damping effect of the first spring 16 to be generated.
