Abstract
A device for emergency hand operation has switching magnets with an armature that can be moved in the pole pipe to a final position by the force of a spring assembly, and can be moved against the spring force to a second final position by a magnetic field excitation. The device has a tensional member which can be axially displaced and moved by a manual actuating device. A carrier interacts with the armature to move the carrier against the spring force and to the second final position. The armature, the pole core, the spring assembly, the tensional member and the actuating device are combined to form a prefabricated component which can be inserted into the pole pipe via its inner open end and which can be connected to the pole pipe.
Claims16
A device for emergency hand operation of switching magnets, comprising:
- a pole pipe having an inner open end;
- an armature movably mounted in said pole pipe from a first position to a second position by magnetic field excitation;
- a spring assembly biasing said armature toward said first position;
- a pole core having an axial bore with an internal thread and having a first annular peripheral groove, said open end of said pole pipe being folded into said first peripheral groove to connect said pole core and said pole pipe;
- a tensioning member axially slidable and guided in said axial bore of said pole core and having a carrier cooperating with said armature to move said armature therewith counter to biasing of said spring assembly, said tensioning member extending through an inner end of said pole core and into an axial bore of said armature;
- and
- a manual actuating threaded bolt axially fixed to said tensioning member to move same axially in said pole core and threadedly engaged with said internal thread, said tensioning member being configured as a one-piece extension of said threaded bolt;
- said armature, said pole core, said spring assembly, said tensioning member and said actuating threaded bolt being combined in a single prefabricated structural unit inserted into said open end.
