The invention relates to a low-frequency vibration isolation device and an elevator. The low-frequency vibration isolation device comprises a mounting seat, an elastic abutting piece, a rigid abuttingpiece, a connecting plate and a fastening connecting piece, wherein the mounting seat is used for being assembled and connected with a car bottom frame; the elastic abutting piece is arranged on themounting seat; the rigid abutting piece is arranged on the elastic abutting piece; the connecting plate is arranged on the rigid abutting piece and used for being assembled and connected with an uppercar bottom; and the fastening connecting piece is used for assembling and connecting the mounting seat, the elastic abutting piece, the rigid abutting piece and the connecting plate and enabling theelastic abutting piece and the rigid abutting piece to generate pre-pressing amounts. The inherent frequency of an elevator car can be remarkably reduced, the low-frequency vibration isolation capacity of the car in the vertical direction is improved, stable operation of the elevator is guaranteed, and the purpose of improving the riding comfort of passengers is achieved. In addition, by adjustingthe locking force of the fastening connecting piece, the rigid abutting piece and the elastic abutting piece generate different pre-pressing amounts, and therefore the low-frequency vibration isolation device can be suitable for occasions with different loads.

    本发明涉及一种低频隔振装置及电梯,包括:安装座,用于与轿底架组装连接;弹性抵压件,所述弹性抵压件设置于所述安装座上;刚性抵压件,所述刚性抵压件设置于所述弹性抵压件上;连接板,所述连接板设置于所述刚性抵压件上并用于与上轿底组装连接;及紧固连接件,所述紧固连接件用于将所述安装座、所述弹性抵压件、所述刚性抵压件以及所述连接板组装连接,并使所述弹性抵压件和所述刚性抵压件产生预压量。可显著降低电梯轿厢的固有频率,提高轿厢在垂直方向上的低频隔振能力,保证电梯运行稳定,达到提升乘客乘坐舒适性的目的。此外,通过调节紧固连接件的锁紧力度,使刚性抵压件和弹性抵压件产生不同预压量,从而能够适用于不同载荷的场合。
