The invention relates to the technical field of elevator speed limiters, in particular to an elevator speed limiter checking device which comprises a bottom support, parallel stand columns are arranged at the upper end of the bottom support, winches which are oppositely arranged are arranged on the upper portions of the stand columns, ropes are wound around the winches, and hooks are fixedly installed at the ends of the ropes. A fixing plate is arranged on the side face of the stand column, a rotating speed sensor is installed on the fixing plate, and a transmission wheel matched with the speed limiter wheel is arranged at the rotating end of the rotating speed sensor. The hook at the end of the rope is placed at the bottom of the steel wire rope located on the speed governor wheel, then the winch is rotated to enable the steel wire rope located on the speed governor wheel to be hoisted, the difficulty that the speed governor steel wire rope is separated from a speed governor wheel groove is lowered, and the steel wire rope is not prone to being damaged; the problems that the tachymeter deviates from or is separated from the speed governor wheel and the measurement result is inaccurate due to the fact that the checking personnel hold the speed governor unstably are solved.

本发明涉及电梯限速器技术领域，尤其是涉及一种电梯限速器校验装置，包括底部支架，所述底部支架的上端设有并列的立柱，所述立柱的上部设有相对设置的绞盘，所述绞盘上缠绕有绳索，所述绳索的端部固定安装有挂钩，所述立柱的侧面设有固定板，所述固定板上安装有转速传感器，所述转速传感器的旋转端设有与限速器轮匹配的传动轮。本发明通过绳索端部的挂钩放置在位于限速器轮上钢丝绳的底部，然后旋转绞盘使得位于限速器轮上钢丝绳被吊起，降低了限速器钢丝绳从限速轮槽中分离的难度，且不容易损坏钢丝绳，另外利用固定板上安装的转速传感器，克服了校验人员手持不稳导致测速仪偏离或脱离限速器轮的问题和测量结果不准确的问题。
