Abstract

The invention relates to the technical field of elevator equipment, and discloses an elevator speed governor which solves the problem that a mechanical triggering mechanism is easily damaged due to the fact that an elevator runs too fast at present. The elevator speed governor comprises a base, a support is fixedly installed at the top of the base, a connecting column is movably installed on the front face of the support, and a detection device is fixedly installed on the front face of the connecting column; a supporting plate is fixedly mounted at the bottom of the detection device; according to the device, through cooperation between a clamping rod and a mounting plate, when a wheel disc vibrates, a second spring stretches out and draws back through cooperation among a movable column, the second spring and a fixing block, and a first spring stretches out and draws back through cooperation among a third rotating rod, a sliding block and a fixing rod; and then force is absorbed through the elastic action of a first spring and a second spring, so that the mounting plate is buffered, a wheel disc is buffered through a clamping rod, and the situation that a mechanical triggering mechanism is easily damaged due to the fact that the running speed of an elevator is too high is avoided.

Description

technical field [0001] The invention belongs to the technical field of elevator equipment, in particular to an elevator speed governor. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or less than 15° from the plumb line. The elevator speed limiter is the elevator four One of the major safety components is to ensure that the elevator can trigger the action of the safety device in time in the case of accidental overspeed, so as to stop the elevator and ensure the safety of life and property of the passengers. [0003] The existing elevator speed limiter has a single structure and poor speed detection performance. When the speed is too fast, it is easy to cause damage to the mechanical trigger mechanism, which in turn affects the normal braking of the equipment and cannot meet the needs of use. ...
