Abstract
The invention discloses a speed limiter tension device for an elevator. When the elevator is overhauled, a beating rod is inserted into an inserted hole of a tension sheave to stop action of the tension sheave and a safety switch is touched by the beating rod, so that a safety loop of the elevator is switched off, the elevator is stopped from operating, a speed limiter steel wire rope and the tension sheave are relatively kept static and a static frictional force between the speed limiter steel wire rope and the tension sheave can be greater than a driving force for enabling the speed limiter steel wire rope to drive an elevator safety tong operation and control mechanism to operate. If the elevator slips by accident, the frictional force between the speed limiter steel wire rope and the tension sheave ensures that the steel wire rope cannot slip in a rope slot of a rope wheel, and thus, when the elevator moves down by accident, the elevator safety tong operation and control mechanism can be driven to operate by the speed limiter steel wire rope so as to brake the elevator, stop the elevator from further moving down, ensure safety of an operator in the pit operating process and improve safety performance of the elevator.
