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, rotatesa 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] Figure 11 to Figure 16 The configuration of a conventional elevator speed controller is shown (for example, refer to Patent Document 1). Figure 11 It is an overall configuration diagram showing an example of an elevator having a conventional elevator governor, Figure 12 is a detailed diagram showing the structure of a conventional governor, Figure 13 is a front view showing the main parts of the governor, Figure 14 is to show Figure 13 Main view of the state where the recovery lever is shaken to the recovery position, Figure 15 is a front view showing the main part of the speed governor when the protrusion is in a position not facing the return lever, Figure 16 is to show Figure 15 Front view of the state where the recovery l...
