The invention relates to elevator accessories, and discloses an elevator top buffer which comprises a buffer shell installed at the top of an elevator shaft. A first sliding block and a second sliding block are arranged in the buffering shell in a sliding mode, a buffering elastic piece is installed between the first sliding block and the second sliding block, a first guide rod is installed on the first sliding block, the first guide rod penetrates through the side wall of the buffering shell, the first guide rod is sleeved with a first buffering spring, and the first buffering spring is arranged between the buffering shell and the first sliding block. A second guide rod is installed on the second sliding block, the second guide rod penetrates through the side wall of the buffering shell, the second guide rod is sleeved with a second buffering spring, and the second buffering spring is arranged between the buffering shell and the second sliding block. The buffer is a two-stage buffer, the buffer elastic pieces are used for longitudinal buffering, the buffer springs are used for transverse buffering, the height of the buffer can be designed to be lower, and therefore the space, used for installing the buffer, of the top of an elevator shaft is smaller. A plurality of buffers may be arranged side by side at the top of the elevator shaft.

    本发明涉及电梯配件,公开电梯顶部缓冲器,包括安装在电梯井顶部的缓冲壳体;缓冲壳体内滑动有第一滑块和第二滑块,第一滑块与第二滑块之间安装有缓冲弹片,第一滑块上安装有第一导向杆,第一导向杆贯通缓冲壳体的侧壁,第一导向杆上套装有第一缓冲弹簧,第一缓冲弹簧设在缓冲壳体与第一滑块之间,第二滑块上安装有第二导向杆,第二导向杆贯通缓冲壳体的侧壁,第二导向杆上套装有第二缓冲弹簧,第二缓冲弹簧设在缓冲壳体与第二滑块之间。本缓冲器为二级缓冲器,缓冲弹片为纵向缓冲,缓冲弹簧为横向缓冲,缓冲器的高度可以设计的更加的低,从而使得电梯井顶部用于安装缓冲器的空间更加的小。数量为多个的缓冲器可以并排布置在电梯井顶部。
