Electronic safety actuator for lifting a safety wedge of an elevator
An electronic safety actuation device for braking an elevator car includes a safety brake movable between a non-braking position and a braking position, a first electronic safety actuator operably coupled to the safety brake via a first link member, and a second electronic safety actuator operably coupled to the safety brake via a second link member. Operation of the first electronic safety actuator applies a force to the first link member to move the safety brake from the non-braking position to the braking position. Operation of the second electronic safety actuator applies a force to the second link member to move the safety brake from the non-braking position to the braking position.
1. An electronic safety actuation device for braking an elevator car comprising:
a safety brake having a movable member movable between a non-braking position and a braking position;
a first electronic safety actuator operably coupled to the movable member of the safety brake via a first link member;
a second electronic safety actuator operably coupled to the movable member of the safety brake via a second link member;
wherein operation of the first electronic safety actuator applies a force to the first link member to move the movable member from the non-braking position to the braking position and operation of the second electronic safety actuator applies a force to the second link member to move the movable member from the non-braking position to the braking position.
2. The electronic safety actuation device of claim 1 , wherein the second link member is coupled to the safety brake via the first link member.
3. The electronic safety actuation device of claim 2 , wherein the first link member and the second link member are connected via a pin and slot engagement.
4. The electronic safety actuation device of claim 2 , wherein the first link member is movable relative to the second link member to move the safety brake from the non-braking position to the braking position.
5. The electronic safety actuation device of claim 2 , wherein the second link member is configured to move in conjunction with the first link member to move the safety brake from the non-braking position to the braking position.
6. The electronic safety actuation device of claim 1 , wherein the first electronic safety actuator and the second electronic safety actuator are integrally formed as a single unit.
7. The electronic safety actuation device of claim 1 , wherein the first electronic safety actuator includes a first housing and the second electronic safety actuator includes a second housing, separate from the first housing.
8. The electronic safety actuation device of claim 1 , wherein the first electronic safety actuator further comprises:
a magnetic brake operably coupled to the first link member, the magnetic brake being movable between a first position and a second position; and
an electromagnetic component configured to hold the magnetic brake in one of the first position and the second position.
9. The electronic safety actuation device of claim 1 , wherein the safety brake includes a wedge having a contact surface, the wedge being movable between the non-braking position and the braking position.
10. An electronic safety actuation device for braking an elevator car comprising:
a safety brake movable between a non-braking position and a braking position;
a first electronic safety actuator operably coupled to the safety brake via a first link member;
a second electronic safety actuator including a second link member, the second link member being operably coupled to the safety brake via the first link member;
wherein operation of the first electronic safety actuator applies a force to the first link member to move the safety brake from the non-braking position to the braking position and operation of the second electronic safety actuator applies a force to the second link member to move the safety brake from the non-braking position to the braking position.
