Therefore, it is particularly important to ensure the safe and punctual operation of rail transit trains to meet people's needs for fast travel. However, during the operation of the train, due to the unevenness of the line, the body of the train will swing slightly left and right. In order to prevent the train from colliding with the platform and meet the requirements of the locomotive vehicle limit, there must be a gap between the train and the platform after the rail transit vehicle stops at the platform. It is precisely because of the existence of this gap that when passengers get on and off the train, small items in their hands, such as mobile phones, keys, wallets, umbrellas, etc., are very easy to fall into the track due to squeezing and collision. Sometimes, the gap even causes the phenomenon of passengers' legs being pinched, which causes great safety hazards and economic losses to the normal operation of rail transit vehicles and the safety of passengers. Some trains have a large distance after stopping at the station, and the conductor will manually lay a baffle to facilitate passengers to get on and off, but the operation is inconvenient, so it is necessary to set up an automatic shielding device.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.
[0024] Example:
[0025] like Figure 1-Figure 4 As shown, a shielding device for the gap between a platform and a train. It includes a fixed frame 1, a baffle 2, a support frame 3, and a lifting mechanism 4. The fixed frame 1 is attached to the vertical surface of the edge of the platform. The baffle 2 is rotatably connected to the upper end of the fixed frame 1. The edge of the baffle 2 is arranged parallel to the upper edge of the fixed frame 1. The baffle 2 is rotatably connected to the upper end of the support frame 3 at the bottom of the baffle 2. The lower end of the support frame 3 is rotatably connected to the lifting mechanism 4. The lifting and lowering of the lifting mechanism 4 drives the support frame 3 to move up and down, thereby driving the baffle 2 to rotate around the hinge shaft to achieve the expenditure and collection of the baffle 2. The lifting mechanism 4 is installed on the fixed frame 1. The lifting mechanism 4 mainly plays a lifting function, which can be a common motor-driven gear rack structure, a screw rod 402 slider 403 structure, etc., or other power forms such as a linear motor and a cylinder. The baffle 2 needs to be disbursed after the train docks and folded when the train is running to avoid hindering the train operation. Of course, this structure can be used in other similar scenes with gaps, such as subways, elevators and other structural scenes.
[0026] For example, a screw rod 402 and a slider 403 structure is adopted, which includes a reduction motor 401, a screw rod 402, a slider 403, and a balance bar 404. The reduction motor 401 is arranged at the lower part of the fixed frame 1, and the reduction motor 401 is connected with the screw rod 402 to drive the screw rod 402 to rotate. The slider 403 cooperates with the screw rod 402, and the balance bar 404 is fixed on the slider 403. The balance bar 404 is connected to the lower end of the support frame 3. The reduction motor 401 provides power. The reduction motor 401 can obtain a stronger torque. When necessary, the drive can be realized in the form of a motor and a gear set. The function of the balance bar 404 is mainly to synchronize the support frames 3 on both sides, and the operation is more stable and in step to prevent jamming, and it has a greater and more uniform driving force for the movement of the baffle 2.
[0027] Auxiliary guide rails 5 are provided at both ends of the balance bar 404. The auxiliary guide rails 5 are provided along the reciprocating direction of the balance bar 404. A dovetail groove structure is used for installation between the auxiliary guide rails 5 and the balance bar 404. The auxiliary guide rails 5 adopt the dovetail groove form to achieve direction guidance and prevent separation, and play a fixing role. Of course, the specific slotting form is varied, and other similar fixing structures can be used, such as a slot structure with side slots, etc. Two auxiliary guide rails 5 can achieve a better guiding effect and prevent the balance bar 404 from deviating and tilting.
[0028] There are two support frames 3, the upper ends of which are rotatably mounted on the left and right sides of the bottom of the baffle 2, and the lower ends of the baffle 2 are rotatably mounted near the auxiliary guide rails 5 set on both sides of the balance bar 404. The support frames 3 are supported from both ends, and the operation is smoother. If necessary, the number of support frames 3 can be increased, and even more synchronously running screws 402 and sliders 403 can be matched to increase the driving force.
[0029] A locking structure is arranged on the fixing frame 1, and the locking structure comprises a self-resetting electromagnet 6 and a locking tongue 7. The self-resetting electromagnet 6 and the locking tongue 7 are installed in cooperation with each other when the balance bar 404 rises to make the baffle 2 horizontal. The self-resetting electromagnet 6 controls the extension and retraction of the locking tongue 7, and the locking tongue 7 acts on the lower bottom surface of the end of the balance bar 404. The locking structure mainly stops the motor from running after the baffle 2 is extended into place, and limits its position to prevent it from sinking when people walk, causing danger. At the same time, it also shares the pressure, reduces the force and impact of the support frame 3, and shares the impact. The locking tongue 7 is a triangular rotating block on a mounting block. The extension and retraction are controlled by an electromagnet, and the reset can be achieved in cooperation with a reset spring. This technology is relatively mature and will not be described here.
[0030] An upper travel switch 8 and a lower travel switch 9 are arranged on the fixed frame 1. The upper travel switch 8 cooperates with the upper end surface of the balance bar 404. The trigger position of the upper travel switch 8 corresponds to the position of the balance bar 404 when the baffle 2 is horizontal; the lower travel switch 9 cooperates with the lower end surface of the balance bar 404. The trigger position of the upper travel switch 8 corresponds to the position of the balance bar 404 when the baffle 2 is fully retracted. The travel switch only senses the position, which is a relatively excellent technical solution. Other sensing methods, such as laser sensors, can also be used. There are two upper travel switches 8, which are respectively arranged at the upper ends of the two auxiliary guide rails 5; there are two lower travel switches 9, which are respectively arranged at the lower ends of the two auxiliary guide rails 5. The travel switches are arranged at both ends to increase fault tolerance and prevent the failure of sensing caused by damage to a single travel switch.
[0031] A PLC controller is provided, and the PLC controller is electrically connected to the upper travel switch 8, the lower travel switch 9, the reduction motor 401, and the self-resetting electromagnet 6. The PLC controller is electrically connected to the host computer, the terminal control box, and the car position sensor. The terminal control box is used to sense the train running into place, and the car position sensor is used to sense the car position. The terminal control box and the car position sensor can be implemented using the equipment of the original track system. The host computer mainly plays the role of receiving alarm signals when the device does not operate correctly. The PLC controller is electrically connected to the upper travel switch 8, the lower travel switch 9, the reduction motor 401, and the self-resetting electromagnet 6 to raise, lower, and lock the position of the baffle 2.
[0032] The upper end of the fixing frame 1 is set to be L-shaped, and the inner side of the corner is intermittently provided with a rotating shaft of a loose-leaf structure, and the rotating shaft of the loose-leaf structure corresponding to the position is set at the edge of the baffle 2. The baffle 2 is rotatably installed on the fixing frame 1 through the rotating shaft of the loose-leaf structure. The L-shape can hide the rotating shaft, which is beautiful and prevents foreign objects from entering. It has a certain rainproof ability and ensures smooth rotation.
[0033] The middle part of the fixing frame 1 is hollowed out to reduce the weight and reduce the friction of the balance bar 404. The upper surface of the baffle 2 is provided with anti-skid patterns to facilitate walking.
