Cable-braking apparatus

A cable-braking apparatus comprising:

• a main body unit at one side of which a main cable is positioned;
• a drive unit, which is provided at another side of the main body unit so as to generate a drive force;
• an elastic compression unit configured to compress or release main elastic elements using the drive force generated by the drive unit;
• a press unit, which is actuated by the elastic compression unit so as to move a press plate, which is provided at one side of the press unit, to thus press the main cable;
• and
• a movement control unit configured to lock or release an anchor pin, which is provided at another side of the press unit, to thus control movement of the press unit,
• wherein the movement control unit includes:
• a solenoid, which is positioned below an anchor pin block of the press unit and a pin cover of which is raised upon application of power and is lowered by a restoring force on interruption of the application of power;
• a lock, which is disposed above the solenoid and is divided into a pair of segments, the lock being configured such that first ends of the segments are opened or closed so as to cause locking grooves, which are formed in second ends of the segments, to hold or release the anchor pin of the anchor pin block when the pin cover is raised or lowered;
• and
• a tension spring, which is provided below the lock so as to provide the lock with restoring force.
