Rotary type train door locking system

Abstract

The invention discloses a rotary type train door locking system which comprises a portal crane beam, a transverse linear guide rail assembly, two train door connecting plates, a synchronous belt transmission assembly, a longitudinal linear bearing assembly, a locking mechanism and the like. According to the rotary type train door locking system, the plugging and pulling movement of the train door on the horizontal plane can be achieved, the effect of completely locking the train door is achieved by locking the transverse movement of the train door through the locking mechanism, the locking principle is simple, and structure installation and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of mechanical locking structures, in particular to a rotary locking system for train doors. Background technique [0002] The train doors of the subway are mainly divided into two types: plug doors and built-in doors. The plug doors are divided into two types: screw type plug doors and belt type plug doors. The operation process of the sliding door is: when the door is closed, the train door is inserted into the door of the car from the inside or outside of the car, and the train door is closed and sealed. When the door is opened, when the train door moves away from the door for a certain distance, Sliding on the inside or outside of the car body. After the train door is closed, it needs to be locked by a locking mechanism to prevent the train door from shaking and opening during operation. [0003] Various types of locking mechanisms have appeared in the prior art, such as the utility model patent with th...

Problems solved by technology

[0003] Various types of locking mechanisms have appeared in the prior art, such as the utility model patent with the notification number CN202672945U, which discloses a switch locking mechanism for rail transit train doors, including: locking shaft, gear shaft, gear , rack, driving door connecting rod, stopper, guide column and spiral cam, etc., when the door reaches the closing end point, the switch locking mechanism directly clamps the rack and pinion mechanism through the stopper to lock. The stroke accuracy of the rack is required to be high, otherwise it is very easy to cause damage caused by the block not being inserted smoothly or forcedly inserted. At the same time, the structure of the rack and pinion components is relatively complicated, and the processing accuracy of the parts is relatively high. Maintenance is more troublesome, which is not conducive to large-scale production and application
