DEVICE FOR CONTROLLING A CLAMPING FORCE

摘要

A clamp with a tripping mechanism in which the force for ensuring safe tripping is obtained via a compound lever mechanism directly from the energy storage element (S), such as a spring, that provides the clamping force.

1. A device for controlling the application of a clamping force through a clamp to an element (D) that is free to move relative to the clamp when it is not clamped, comprising at least one energy storage element (S) providing the clamping force, a mechanism for opening the clamp comprising at least one element acting as a lever having a short arm and a long arm, in which the long arm is activated by a wedge arrangement comprising a nut moved by a screw rod, and a tripping arrangement causing instant application of the clamping force,
wherein the tripping mechanism is biased to trip by means of a force that is directly derived from the energy storage element (S) via said mechanism for opening the clamp.
