Automatic-reset support equipped with stepless regulating friction energy dissipation device
The invention relates to an automatic-reset support equipped with a stepless regulating friction energy dissipation device. The support comprises a connection transmission mechanism, an automatic-reset mechanism and a friction energy dissipation mechanism, wherein the connection transmission mechanism comprises an outer sleeve, an inner sleeve, two end connecting plates and two end plates, the inner sleeve is arranged in the outer sleeve and is fixed to the outer sleeve in a radial direction, the two end connecting plates are located at two opposite ends and are fixedly connected to the ends of the inner sleeve and the outer sleeve correspondingly, the two end plates are located on the two axial sides of the outer sleeve and the inner sleeve correspondingly; and the friction energy dissipation mechanism comprises two inner friction plates, two outer friction plates and pre-tightening bolts, wherein the two inner friction plates, the two outer friction plates and the pre-tightening bolts are fixed on the outer sleeve and the inner sleeve, and the two outer friction plates clamp the two inner friction plates through pre-tightening bolts. Compared with the prior art, the support can solve the conflict between supporting energy dissipation capacity and the automatic-reset capacity, obstruction of supporting reset is reduced while the reliable energy dissipation capacity is provided, and flexibility of supporting loading and unloading rigidity and yield bearing capacity adjustment is realized.
本发明涉及一种配置无级调节摩擦耗能装置的自复位支撑，包括：连接传力机构：包括外套筒、内套筒、两个端部连接板和两个端板，内套筒置于外套筒内，并与外套筒径向相对固定，两个端部连接板位于相对的两端，并分别固定连接内套筒和外套筒的端部，两个端板分别位于外套筒和内套筒的轴向两侧；自复位机构；摩擦耗能机构：包括分别固定在外套筒和内套筒上的两个内摩擦板、两个外摩擦板、以及预紧螺栓，两个外摩擦板通过预紧螺栓夹紧两块内摩擦板。与现有技术相比，本发明可以解决支撑耗能能力和自复位能力之间的冲突，在提供可靠耗能能力的同时减少对于支撑复位的阻碍，并实现支撑加卸载刚度和屈服承载力调节的灵活性。
