Description

Technical Field

[0001] The present invention belongs to the field of rail transit fire evacuation, and in particular relates to a railway evacuation platform structure on the same line of a city railway and a national railway. Background Art

[0002] With the rapid development of my country's railway modernization, the railway system and operation mode are becoming more and more diversified. In order to promote regional urbanization, some regions have adopted the mode of through-operation of national railway lines and urban rail transit lines (such as the Shanghai Urban Railway Airport Link Line). Through co-line operation, line resources can be fully utilized to improve transportation efficiency, while effectively bringing convenience to passengers, thereby accelerating the development of the region. However, the co-line operation of vehicles of different systems also brings problems in the design of evacuation platforms.

[0003] The design of the evacuation platform for urban rail can refer to the subway and national railway. In the conventional design of the subway, an evacuation platform is usually set up on the side of the tunnel, which is slightly lower than the height of the carriage floor and does not exceed the equipment limit in the horizontal direction. The evacuation platform is close to the side door and has a small height difference, which is convenient for passengers to evacuate smoothly and safely. The evacuation method of the national railway tunnel train is to use the cable trench covers on both sides as evacuation channels, which have a large height difference and are far from the door. In order to ensure the safe evacuation of passengers, an evacuation ladder needs to be installed at the door.

[0004] The evacuation platform of the urban rail should be set up close to the subway to make the evacuation path as flat as possible. However, for the urban rail that is interconnected with the national railway, the limit requirements of the national railway (intercity railway) need to be considered. If an evacuation platform in the form of a subway is used, with the same height as the carriage floor, it is bound to exceed the construction limits required by the national railway. If it does not exceed the limit, the evacuation platform will be too far away from the car, making safe evacuation impossible. Summary of the invention

[0005] In view of at least one of the above defects or improvement needs of the prior art, the present invention provides a railway evacuation platform structure for the urban area and the national railway on the same line. By rotating the motor and the connecting rod to change the position of the evacuation platform during normal operation and emergency evacuation, the limit problem of the urban railway evacuation platform in the same line operation with the national railway is solved, and the evacuation platform is closely connected with the vehicle when in use, reducing the safety risk during evacuation.

[0027] Preferably, the evacuation platform fixing plate is fixed to the tunnel wall 8 on the outer side of the collinear railway and is supported and reinforced by diagonal supports.

[0028] Preferably, the evacuation platform fixing plate is fixed to the roadbed on the outer side of the co-linear railway through a truss.

[0047] like Figure 1-3 As shown, the present invention provides a railway evacuation platform structure for a city railway and a national railway on the same line, taking into account the evacuation of personnel on both city trains and national railway trains on the shared line railway, and includes a partially flippable evacuation platform panel 1, a flipping mechanism 4, and a locking device.

[0048] The evacuation platform panel 1 includes an evacuation platform fixed plate 101 and an evacuation platform movable plate 102; the evacuation platform fixed plate 101 is fixed on the outside of the collinear railway and never intrudes into the construction limit outline 6 of the intercity railway.

[0049] The rear end of the evacuation platform movable plate 102 is flipably connected to the evacuation platform fixed plate 101 via a hinge 3 , and is flipped and switched between a horizontal working state and a suspended state under the actuation of the flip mechanism 4 .

[0050] In the horizontal working state, the front end of the evacuation platform movable plate 102 intrudes into the intercity railway building clearance contour line 6 but does not intrude into the urban train clearance 7.

[0051] In the suspended state, the movable plate 102 of the evacuation platform as a whole does not intrude into the construction boundary contour line 6 of the intercity railway.

[0052] The locking device is used to lock the evacuation platform movable plate 102 in the switched state.

[0053] Preferably, the flipping mechanism 4 includes a rotating motor 401, a connecting rod 1 402, and a connecting rod 2 403; one end of the connecting rod 1 402 is hinged to the evacuation platform fixed plate 101, and the other end is hinged to the connecting rod 2 403, and the other end of the connecting rod 2 403 is hinged to the evacuation platform movable plate 102; the rotating motor 401 is used to actuate the rotation of one of the connecting rods 1 402 and 403 and push the other, thereby actuating the flipping of the evacuation platform movable plate 102.

[0054] Preferably, the locking device comprises a latch mechanism 5; the latch mechanism 5 comprises a latch motor 501 and a latch rod 502; the latch motor 501 is fixedly connected to the evacuation platform fixed plate 101, and drives the latch rod 502 to extend and retract forward and backward.

[0055] In the horizontal working state, the latch motor 501 drives the latch rod 502 to extend forward to the bottom of the evacuation platform movable plate 102 to fix, support and carry the load.

[0056] In the suspended state, the latch motor 501 drives the latch rod 502 to retract and interlock with the rotating shaft of the rotating motor 401 of the flip mechanism 4, and indirectly locks the movable plate 102 of the evacuation platform through the rotating motor 401, connecting rod 1 402 and connecting rod 2 403.

[0057] Preferably, the rotating motor 401 is fixedly connected to the evacuation platform fixed plate 101. Figure 1-3 The one shown is fixed below the fixed plate of the evacuation platform to achieve the flipping of the movable plate of the evacuation platform between horizontal and downward; the other is fixed above the fixed plate of the evacuation platform (not shown) and on both sides of the platform unit to achieve the flipping of the movable plate of the evacuation platform between horizontal and upward. Correspondingly, the latch motor 501 and the latch rod 502 are also fixed above and on both sides, and a fixed locking ring or locking block is added above the movable plate 102 of the evacuation platform in the horizontal working state, which is used to lock with the extended latch rod 502, and also plays the role of fixing, supporting and bearing.

[0058] In the tunnel application scenario, the evacuation platform fixing plate 101 is fixed on the tunnel wall 8 on the outside of the collinear railway and is supported and reinforced by the inclined support 2 .

[0059] In the road-bridge section, the evacuation platform fixing plate 101 is fixed on the roadbed outside the collinear railway through a truss.

[0060] Preferably, the height of the evacuation platform movable plate 102 in the horizontal working state is less than or equal to the height of the door bottom plate of the urban train, and is also less than or equal to the height of the door bottom plate of the intercity railway train.

[0061] The evacuation method of the railway evacuation platform structure of the present invention, which has a common line between the city and the national railway, comprises the following steps:

[0062] A. For urban trains on the shared railway:

[0063] When the interval train is running, the evacuation platform movable plate 102 is in a suspended state, and the rotating shaft of the rotating motor 401 is engaged and interlocked with the retracted latch rod 502 to ensure that the positions of the connecting rod 1 402, the connecting rod 2 403 and the evacuation platform movable plate 102 are fixed, so as to avoid the pressure difference caused by the running of the train or the external wind force, etc., which causes the evacuation platform movable plate 102 to swing closer to the train. In order to avoid intrusion, the evacuation platform movable plate 102 is located outside the construction limit contour line 6 of the intercity railway as a whole;

[0064] When the train in the section needs to stop and evacuate urgently due to fire, geological disasters, etc., the latch rod 502 extends forward to release the interlock with the rotating motor 401, and the rotating motor 401 drives the connecting rod 1 402 and the connecting rod 2 403 to push the evacuation platform movable plate 102 to flip until the evacuation platform movable plate 102 and the evacuation platform fixed plate 101 are at the same horizontal line, together forming the evacuation platform panel 1, and the latch motor 501 continues to push the latch rod 502 to extend, hold up the evacuation platform movable plate 102, carry the passenger load and limit the downward flipping, the front end of the evacuation platform movable plate 102 invades the intercity railway construction limit contour line 6 but does not invade the urban train limit 7, so the embodiment of the present invention selects 1750mm as the distance between the evacuation platform movable plate and the line center line when working, and the distance between the platform and the vehicle contour line can be adjusted according to the needs of the line; the passengers first get off the train to the evacuation platform movable plate 102 and then evacuate through the evacuation platform fixed plate 101.

[0065] B. For national railway trains on the shared railway:

[0066] When the section train is running, the evacuation platform movable plate 102 is in a suspended state, and the rotating shaft of the rotating motor 401 is engaged and interlocked with the retracted latch rod 502, ensuring that the positions of the connecting rod 1 402, the connecting rod 2 403 and the evacuation platform movable plate 102 are fixed, and the evacuation platform movable plate 102 is prevented from swinging due to external factors. The evacuation platform movable plate 102 is located outside the intercity railway construction limit contour line 6 as a whole;

[0067] When the train in the section needs to stop and evacuate urgently due to fire, geological disasters, etc., the turnover mechanism 4 does not move, the evacuation platform movable plate 102 remains in a suspended state, and passengers go directly from the train to the evacuation platform fixed plate 101 for evacuation.

[0068] Preferably, the control system of the evacuation platform structure is linked with the railway signal system, wherein, when the urban train stops in an emergency, the evacuation platform movable plate 102 on the evacuation path is flipped and raised according to the train position fed back by the railway signal system and the evacuation path of the emergency plan, so that the evacuation platform can be flexibly controlled according to the evacuation needs; and when the evacuation platform movable plate 102 is raised, the railway signal system activates the protection mechanism, and the trains in the section where it is located cannot run to avoid safety accidents.
