Preferably, the sliding door 2 and the fixed door 1 form a telescopic structure, the bottom end of the sliding door 2 is fixedly provided with the pulley strip 27 through a screw, the lower surface of the fixed door 1 is fixedly provided with the pulley groove 32 through a screw, the pulley strip 27 is arranged on the inner side of the pulley groove 32, and the pulley strip 27 and the pulley groove 32 form a sliding structure, as shown in fig. 2, the pulley groove 32 is fixedly arranged at the bottom end of the fixed door 1, the pulley strip 27 is arranged at the bottom of the sliding door 2, and the pulley strip 27 slides in the pulley groove 32, so that the stability of the sliding door 2 during movement is improved.
The working principle is that firstly, when the fixed door 1 and the movable door 2 are assembled, a groove is needed to be formed in the ground of a BRT bus station, so that the pulley groove 32 can be embedded into the groove, meanwhile, the fixed door 1 can be fixedly connected with the ground through an expansion screw, then the control unit 11 is electrically connected with a control computer of a station dispatching room through a wire, so that the control unit 11 is in an electrified state, an electric component servo motor 16 and an electric push rod 28 in the fixed door 1 can be directly and electrically connected with the control unit 11 through a connecting terminal, the control unit 11 is controlled through a control computer in an external dispatching room, and the control unit 11 controls the servo motor 16 and the electric push rod 28 to work.
When the movable door 2 needs to be opened, an external control computer sends a control command electric signal to the control unit 11 through a wire, the control unit 11 controls the servo motor 16 to execute through the wire, the servo motor 16 is electrified to rotate anticlockwise, the servo motor 16 is matched with the driving gear 15 through the first belt pulley 13 and the belt 14 and the second belt pulley 17 to rotate anticlockwise, the gear 15 can be used for poking the first fixed rail 5 to move leftwards, the first fixed rail 5 drives the movable door 2 to retract into the fixed door 1, and similarly, the movable door 2 can extend out of the fixed door 1 through clockwise rotation of the servo motor 16.
When the control unit 11 or the internal components of the fixed box 12 have faults, the fixed box 12 can be detached for maintenance only by opening the access door 3, and when the control unit 11 has faults, the control unit 11 only needs to pull out the connecting terminal and then detach the control unit 11 from the fixed door 1 for maintenance.
When the first fixed rail 5, the connecting rail 6 and the second fixed rail 7 are deformed after long-term use, and the like, and maintenance is needed, the first fixed rail 5, the connecting rail 6 and the second fixed rail 7 can be sequentially pulled out from the rail mounting bin 4 for targeted maintenance only by taking down the fixing screws at the connecting positions of the connecting piles 19 and the fixing piles 20, so that the movable door 2 is not required to be detached, and the maintenance is very convenient.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
