FIELD: construction.SUBSTANCE: turnstile comprises barrier, upper and lower plates of mechanism with bearing assemblies, shaft of mechanism, rotor, rotatably mounted in bearing assemblies, coupling sleeve between the shaft of mechanism and rotor, obstructive bars connected with rotor, refinement and positioning mechanism, mechanism for locking the rotor, refinement damping mechanism of obstructive bars up to the initial position, electronic control unit, sensor of angular position of rotor, light indication and remote control panel. In accordance with the invention, refinement damping mechanism is designed as a hydraulic clutch, electromagnetic brake clutch and over drive from the shaft of mechanism to the hydraulic clutch. In this case, the leading portion of hydraulic clutch is rigidly and coaxially connected to the driven pulley of over drive, preferably toothed-belt drive. And the loose side of hydraulic clutch is rigidly and coaxially connected to the movable part of electromagnetic brake clutch.EFFECT: use of more technological and reliable mechanism for damping turn of obstructive bars when passing through the turnstile, which increases the smoothness of operation and reliability of turnstile and reduces costs for its manufacture.2 cl, 4 dwg |
