Abstract

A speed governor for an elevator, whose return operation can be performed from the outside of a hoistway even if an elevator car is at the top of the hoistway. The speed governor has a return lever, operation means, and rotation means. The return lever is displaceable between a normal position and a return position and which, when displaced from the normal position to the return position, rotates a claw to engage it with a trip lever. The operation means displaces the return lever by remote operation. The rotation means forcibly rotates a rope sheave, even if the car is in standstill, to the direction same as the direction in which the rope sheave is rotated when the car is moved upward, thereby moving the claw to the position of the return lever.

Description

technical field [0001] The present invention relates to an elevator speed governor which is provided with a speed governor in a hoistway, and which can perform remote recovery even when the car is at the top. Background technique [0002] 11 to 16 show the configuration of a conventional elevator governor (for example, refer to Patent Document 1). Fig. 11 is an overall configuration diagram showing an example of an elevator having a conventional elevator governor, Fig. 12 is a detailed diagram showing the structure of a conventional governor, and Fig. 13 is a main part showing the governor Figure 14 is a front view showing the state in which the recovery lever in Figure 13 is swung to the recovery position, and Figure 15 is a front view showing the main part of the governor when the protrusion is not facing the recovery lever. Front view, FIG. 16 is a front view showing a state in which the return lever of FIG. 15 is swung to the return position. [0003] In FIG. 11 , a dr...
