Rail transit shielding door locking and unlocking device
The invention discloses a rail transit shielding door locking and unlocking device. According to the rail transit shielding door locking and unlocking device, an electromagnetic limiting mechanism is arranged on a fixed door, a mechanical limiting mechanism is arranged on a movable door, a manual unlocking execution mechanism is arranged on a movable door body; a limiting check block structural member is connected to a support in a rotary mode, a protruding check block is arranged at a B end of the limiting check block structural member, and an electromagnet of the electromagnetic limiting mechanism forms a block for the check block in a stretching out state in order to lock the mechanical limiting mechanism; the manual unlocking execution mechanism comprises a door opening spanner mechanism and a connecting rod mechanism, the lower end of the connecting rod mechanism is connected with the B end of the limiting check block structural member through a soft shaft, when the door opening spanner mechanism is pulled, a shifting fork drives the connecting rod mechanism to move upwards, the soft shaft is pulled, the B end of the limiting check block structural member is driven to move in the direction far away from the electromagnet, and therefore unlocking is finished. Through the structure, the rail transit shielding door locking and unlocking device locks and unlocks a shielding door physically, is small in occupied space and convenient to install, and can achieve automatic locking and manual unlocking even in a power loss state.
