In combination with a specific practical situation, the over-rail splicing block 102 is normally of two-block structure and is used for matching with a rail vehicle to run, and the threshold plate 101 is optionally formed by laying a channel steel plate on a ground plane to form a threshold structure suitable for being matched with a shielding door leaf in a shielding manner. That is to say, for the rocker panel 101 of the present embodiment, the rocker panel 101 is not an integrated whole block, but the connection between two adjacent rocker panels 101 is realized through the cross rail splicing block 102, and the structure designed in this embodiment is mainly that when the rocker structure is suitable for the environment where the rail vehicle needs to pass through, the guide groove 103 suitable for the rail vehicle to pass through is prefabricated directly on the cross rail splicing block 102. Under the structure, the problem that the threshold structure is not required to be adjusted when the rail vehicle passes through is solved, the rail vehicle can pass through directly, and the rail vehicle is convenient and efficient to use.

Thus, when the shielding butt joint of the shielding door leaf and the threshold structure is carried out, the conductive filling block 105 is just filled in the guide groove 103, and a shielding matching structure at the matching position of the guide groove 103 and the conductive filling block 105 is formed, so that the problem of shielding leakage in the guide groove 103 is avoided.

The conductive filling block 105 of the present embodiment is preferably made of an elastic conductive material, so as to ensure the filling effect of the conductive filling block 105 and the guide groove 9.

Because this embodiment has set up bellied electrically conductive stuff 105 on the terminal surface of door leaf body towards threshold board 101, so adopt to such structure and use ripe can make the door leaf body can't make the door leaf body open for the threshold for the vertical direction of door opening and parallel direction's removal in the prior art, make electrically conductive stuff 105 break away from with guide slot 103, that is to say need realize the elevating movement of door leaf body relative to the door opening on carrying out the door leaf body relative to the motion dimension of door opening so that electrically conductive stuff 105 breaks away from guide slot 103 after can carry out the door leaf body relative to the door opening parallel direction's removal, and make the door leaf body open for the door opening completely, form the effect of the current space of rail vehicle of being convenient for of door opening department. Therefore, in view of the above problem, the door body structure of the present embodiment further includes a door lifting mechanism connected to the top end portion of the door body away from the threshold plate 101. The door leaf lifting mechanism is suitable for hanging the door leaf body on a guide rail arranged above the door leaf body.

For example, the door leaf lifting mechanism adopted in the present embodiment includes at least one pair of connecting frames 3 suspended on the guide rail 2, and worm and gear lifting pairs respectively disposed between the at least one pair of connecting frames 3 and the shielding door leaf 1; wherein, one end of the worm gear lifting pair far away from the connecting frame 3 is connected with a lifting seat frame 5; the lifting seat frame 5 is fixedly connected with the top end face of the shielding door leaf 1, so that the lifting seat frame 5 drives the shielding door leaf 1 to synchronously do lifting motion relative to the door opening.

It should be noted that, for the cooperation between the connecting frame 3 and the guiding track 2, for example, a longitudinal x-axis displacement guide rail perpendicular to the door opening and a transverse y-axis displacement guide rail parallel to the plane of the door opening in the fully automatic suspended arc-shaped guide rail two-dimensional electromagnetic shielding door disclosed in the publication No. CN102661113A may be adopted, so that the connecting frame 3 may perform a parallel-direction translation movement and a perpendicular-direction translation movement relative to the guiding track 2, and here, only the traveling trolley 6 suitable for traveling on the guiding track 2 may be connected to the connecting frame 3 to perform the parallel-direction translation movement and the perpendicular-direction translation movement relative to the guiding track 2. This embodiment is not absolutely limited.

For example, in the case of an alternative embodiment, the worm and gear lifting pair comprises a screw rod 4 and a worm and gear speed reducing assembly which is suitable for driving the screw rod 4 to rotate; the lifting seat frame 5 is connected with the movable end of the screw rod 4, and a bearing can be arranged between the movable end of the screw rod 4 and the lifting seat frame 5 for transition, so that the lifting seat frame 5 only can generate lifting motion relative to a door opening under the action of the screw rod 4, and the rotating motion along with the operation of the screw rod 4 can not be generated. In addition, the worm and gear speed reducing assembly is fixed on a supporting frame body 7, the supporting frame body 7 is fixedly connected with the connecting frame 3, and the screw rod 4 penetrates through the supporting frame body 7; the worm and gear speed reducing assembly comprises a speed reducing motor and a worm and gear unit 15 connected with the speed reducing motor 16; when the speed reducing motor drives the worm wheel and the worm to operate, the screw rod 4 does lifting motion relative to the supporting frame body 7. The lifting movement of the lifting seat frame 5 relative to the support frame body 7 is driven by the lifting movement of the screw rod 4, so that the lifting movement of the shielding door leaf 1 relative to the door opening is realized.

In order to achieve a stability of the screen door leaf 1 during the lifting movement, a plurality of connecting brackets 3, i.e. more than two, may be required for one screen door leaf 1.

The detachable assembly of the transition sleeve 9 and the connecting frame 3 can be realized by detaching the connecting shaft 10 and the connecting frame 3.

In addition, a fixing plate 11 is further connected to the end of the supporting frame body 7 far away from the connecting frame 3, the fixing plate 11 is optionally fixedly connected to the end of the supporting frame body 7 far away from the connecting frame 3 through screws, the fixing plate 11 is connected to the lifting seat frame 5 through a guide assembly, and the lead screw 4 penetrates through the fixing plate 11 so that the movable end of the lead screw 4 can be connected to the lifting seat frame 5. The specific guiding component comprises a lifting rod 12 and a fixed rod 14 which are movably sleeved; one end of the fixing rod 14 is fixedly connected with the fixing plate 11, and one end of the lifting rod 12 far away from the fixing rod 14 is fixedly connected with the lifting seat frame 5. The meaning that this embodiment set up the direction subassembly lies in realizing that lead screw 4 drives lifting seat frame 5 and carries out the in-process of elevating movement, can play the spacing effect of direction to lifting seat frame 5 lifting track.

In a further alternative embodiment, an elastic connecting cord 20 may also be provided between the fixed plate 11 and the lifting seat frame 5. The stability and firmness of the connection between the shielding door leaf 1 and the fixing plate 11 can be further improved by the structure of the connecting rope 20.

The specific implementation principle of the door leaf lifting mechanism of the embodiment is as follows: after the speed reducing motor starts to operate, the screw rod 4 drives the lifting seat frame 5 to move upwards or downwards relative to the supporting frame body 7 under the action of the worm gear unit, so that the lifting seat frame 5 synchronously drives the shielding door leaf 1 to realize the ascending or descending movement of the shielding door leaf 1 relative to the door opening. The motion requirement of the shielding door leaf 1 relative to the door opening in a three-dimensional state can be realized by combining the widely used shielding door leaf 1 in the prior art and moving the shielding door leaf 1 relative to the door opening in the vertical direction and the parallel direction.

For the shielding door structure suitable for the rail vehicle in the embodiment, when the rail vehicle does not need to pass through, the door leaf body is just filled in the guide groove 103 by the conductive filling block 105 under the effect of the door leaf lifting mechanism when the door leaf body is in shielding fit with the threshold plate 101, so that good shielding efficiency between the shielding door leaf and the threshold structure is effectively ensured. When rail vehicle is current in needs, the elevating system makes the door leaf body do the ascending motion for the door opening on the passing gate, thereby make electrically conductive packing piece 105 break away from guide slot 103, be convenient for the door leaf body to remove and realize the effect that the door leaf body exposes the door opening along the parallel direction of door opening, so expose the back that shelters from that does not have the door leaf body at the door opening, rail vehicle can directly utilize guide slot 103 to lead to the car, so can realize the good shielding efficiency between rail vehicle's the good shield door structure that is applicable to rail vehicle that this embodiment can realize rail vehicle's the car that leads to and can effectively guarantee shielding door leaf and threshold structure.
