Problems solved by technology

However, due to the limitation of the size of the damping material in the existing soft metal damper, the output of the damper fluctuates greatly, and the damping output becomes smaller when the displacement is large, which cannot meet the actual engineering needs

Embodiment Construction

[0016] Combine below Attached picture The present invention will be further described with specific embodiments.

[0017] as shown in the picture and Figure Institute A nested large-stroke lead damper is shown, including an outer sleeve 1, an inner sleeve 2, a center rod 3, and a lead block 4; it is characterized in that: the outer sleeve 1 is set on the outer surface of the inner sleeve 2 , the inner sleeve 2 is set on the outer surface of the center tie rod 3; grooves are arranged on the two contact surfaces of the center tie rod 3 and the inner sleeve 2, and the grooves on the upper and lower surfaces are opposite to form an annular cavity; 1 and the inner sleeve 2 are provided with grooves on both contact surfaces, the groove of the outer sleeve 1 is longer than the groove of the inner sleeve 2 along the shear direction, and the grooves on the upper and lower surfaces are opposite to each other, forming a variable cross-section An annular cavity; a lead block 4 with ...

Abstract

The invention discloses an embedded type large-stroke lead damper, and belongs to the field of damping control. The embedded type large-stroke lead damper comprises an outer sleeve, an inner sleeve, a central pull rod and lead blocks. The inner sleeve is sleeved with the outer sleeve. The central pull rod is sleeved with the inner sleeve. Grooves are formed in the two contact faces between the central pull rod and the inner sleeve respectively, and the grooves of the upper surface and the lower surface are opposite and form an annular cavity. Grooves are formed in the two contact faces of the outer sleeve and the inner sleeve respectively, the length of the groove, in the shearing direction, of the outer sleeve is larger than the length of the groove, in the shearing direction, of the inner sleeve, the grooves of the upper surface and the lower surface are opposite and form a section-variable annular cavity. The lead blocks are embedded in the cavities, wherein the sizes of the lead blocks are the same as the sizes of the cavities. A plurality of existing shearing type lead dampers are connected in series in an embedded mode, and therefore the stroke of the lead shearing damper is increased, damping materials are layered, the shearing area of the lead blocks is enlarged, and the energy consumption capacity of the lead shearing damper is improved.

Description

Technical field: [0001] The invention relates to a nested large-stroke lead damper, which is suitable for shock-absorbing control of building structures and belongs to the field of shock-absorbing control. Background technique: [0002] The lead shear damper is a shock-absorbing control device that uses the shear plastic deformation of lead to dissipate vibration energy. It has the advantages of full hysteresis, stable performance, simple structure, and convenient processing. It can not only be used for shock absorption, but also The flexible structure is an effective way to solve the vibration problem, and the application prospect is very broad. [0003] An invention patent application [200810057382.6] for a "shear-type lead damper" authorized by the State Intellectual Property Office, such as figure 1 As shown, the damper includes: two upper and lower cover plates 6, a sliding plate 7 and a shear lead weight 4, the lead weight 4 is placed in the groove between the cover p...
