Device for immobilizing an element of a kinematic system

摘要

A device for immobilizing an element (1) of a kinematic system comprising a member (11) having on its periphery upstanding parts and recessed parts of complementary profile to upstanding and recessed parts of the element to be immobilized and mounted at the end of an arm (14), a unit for moving the member (11) between a passive position disengaged from the element (1) to be immobilized and an position in which the respective upstanding and recessed parts of the element (1) and the member interpenetrate to immobilize the element (1) for placing the upstanding parts opposite the recessed parts of the element (1) and the member (11), respectively, and a device for detecting the position of the arm (14) carrying the member (11). The invention applies to immobilizing a toothed ring of a steelmaking converter ladle.
