Description
Technical Field
The invention relates to the technical field of urban rail transit platform doors, in particular to an improved structure of a baffle of a platform door.
Background
Among the prior art, generally be applied to urban rail transit platform door, especially subway platform door, have the safety risk because of having the clearance between its and the train, perhaps the clearance is too big on the one hand, leads to the passenger to drop into the side clearance carelessly in the in-process of getting on or off the bus, and on the other hand perhaps the clearance undersize leads to the train to go when passing the station side scraping platform door and damage platform door and train. Fixed baffles are arranged on the traditional platform doors, the baffles are a pair of hard plates and are symmetrically arranged on the left side and the right side of one surface, facing a track, of a sliding door of the platform door, and are used for preventing passengers or objects from carelessly falling into gaps between the platform doors on the two sides of the sliding door and a train when passing in and out. The size of the baffle plate is slightly smaller than the distance between the platform door and the train, so that the train is prevented from being scraped due to the fact that the baffle plate extends out of the platform door too far. However, there is a possibility that the clearance becomes excessively large or the train is scratched due to an influence of an installation error or the like.

Detailed Description
The invention will be further described with reference to an embodiment shown in the drawings.
As shown in fig. 1 and 6, the passive side wall of the platform door of the present invention mainly comprises: the sliding door comprises a sliding door fixing plate 1, a baffle plate 2, a door beam fixing plate 3, a door beam guide rail 4 and a rolling shaft 5.
The sliding door fixing plate 1 is fixedly installed on a sliding door 9 of the platform door, and preferably, the sliding door fixing plate 1 is installed on a vertical door frame 91 at one end of the sliding door 9 in the closing direction and close to one side of the track.
One side of the baffle plate 2 is hinged to the sliding door fixing plate 1 through a fixing plate hinge 11, so that the baffle plate can be outwards turned and opened or inwards turned and retracted.
The door beam fixing plate 3 is fixedly arranged below a door beam on the side, close to the track, of the sliding door 9 of the platform door.
The door beam guide 4 is fixed to the bottom surface of the door beam fixing plate 3, and as shown in fig. 3 or 5, the door beam guide 4 has a straight line section 41 parallel to the sliding direction of the sliding door 9 and a bent section 42 extending obliquely to the platform side along the end of the straight line section 41, and the bent section 42 is close to the closing joint of the sliding doors 9 on the left and right sides.
The roller 5 is installed on the door beam guide rail 4 in a matching way so as to slide along the door beam guide rail 4, and the roller 5 is hinged to the middle of the top of the baffle 2 through a baffle hinge 21.
Therefore, when the sliding door 9 slides in the opening or closing direction, the sliding door 9 will simultaneously drive the sliding door fixing plate 1, the baffle plate 2 and the roller 5 to move.
When the sliding door 9 is in a closed state, as shown in fig. 2 and 3, the roller 5 slides to the end of the bent section 42 of the door beam guide 4, and the baffle 2 is in an inwardly retracted state. When the sliding door 9 is opened, as shown in fig. 4 and 5, the sliding door fixing plate 1 fixedly connected with the sliding door 9 drives the baffle 2 and the roller 5 to move, the roller 5 slides along the bending section 42 of the door beam guide rail 4 towards the straight section 41 to drive the baffle 2 to gradually turn outwards to open, and when the roller 5 slides to the joint of the bending section 42 of the door beam guide rail 4 and the straight section 41, the baffle 2 is completely opened to shield the gap between the platform door and the train.
When the sliding door 9 is closed, the sliding door fixing plate 1 drives the baffle 2 and the roller 5 to move in opposite directions, the roller 5 slides along the straight line section 41 of the door beam guide rail 4 to the bending section 42 to drive the baffle 2 to turn inwards gradually and retract, and when the sliding door 9 is in a completely closed state, the baffle 2 is completely retracted, so that the phenomenon that a train scrapes the baffle when running through the sliding door is avoided.
It can be seen that the baffle 2 is pulled to open and retract by the sliding of the sliding door 9, without an electrical system and a signal system, which can significantly reduce the production cost and the power consumption and completely avoid electrical faults.
In addition, in order to assist in supporting the baffle 2 when the baffle 2 is opened and to increase the structural strength of the baffle 2 when being pushed by a person, as shown in fig. 6 and 7, the passive side baffle for platform door of the present invention is further provided with: the movable rib plate 6, the pressure lever 7 and the limit boss 8.

The movable ribbed plate 6 can pry the pressure lever 7 to move upwards under the action of gravity by taking the ribbed plate hinge 12 as a fulcrum, so that the top of the pressure lever 7 is abutted against the limiting boss 8 or the door beam fixing plate 3. Preferably, the bottom surface of the limit boss 8 is connected with the bottom surface of the door beam fixing plate 3 through a transition inclined surface 81 at one end close to the bending section 42 of the door beam guide rail 4, and the top of the pressure lever 7 is an arc surface, so that the top of the pressure lever 7 can smoothly move from the bottom surface of the door beam fixing plate 3 to the bottom surface of the limit boss 8.
Preferably, as shown in fig. 1, the upper and middle parts of the sliding door fixing plate 1 of each side sliding door 9 are provided with an upper and a lower movable rib 6, and the upper and the lower movable ribs 6 are hinged with a pressing rod 7.
When the sliding door 9 is opened, the sliding door fixing plate 1 drives the pressing rod 7 to move, as shown in fig. 7, the top of the pressing rod 7 slides from the bottom surface of the door beam fixing plate 3 to the bottom surface of the limiting boss 8, so that the pressing rod 7 moves downwards to turn and lift the movable rib plate 6 upwards and prop against the inner side of the opened baffle plate 2. When the sliding door 9 is closed, the sliding door fixing plate 1 drives the pressing rod 7 to move, as shown in fig. 6, the top of the pressing rod 7 slides from the bottom surface of the limiting boss 8 to the bottom surface of the door beam fixing plate 3, and the movable rib plate 6 turns downwards under the action of gravity to be folded, so that the baffle plate 2 can turn inwards to be retracted.
