Description
Technical Field
The invention relates to the technical field of vacuum trains, in particular to a vacuum train gas-barrier access system.
Background
Whether a magnetic levitation train or a vacuum pipeline train is usually towed by a linear motor, one stage of which is fixed to the vacuum pipeline or the ground and extends along the track to a distance; the other stage is mounted on the vehicle body, the primary is communicated, and the vehicle body moves along the track. The magnetic body is arranged on the vehicle body, when the magnetic body moves along with the vehicle body, induced current is generated in a coil (or an induction plate) arranged on the ground or in a vacuum pipeline, and the vehicle body is suspended by electromagnetic force generated between a magnetic field of the induced current and the magnetic body on the vehicle body.
The wheel body or the magnet on the existing vacuum train is usually arranged on the side surface of the train, so that the opening and closing of the cabin door are easy to be blocked, if the cabin door is arranged on the side surface of the train, on one hand, the size of the cabin door can be limited, and the arrangement of the magnet can be limited by the cabin door; on the other hand, the side wall of the train is opened with a larger area, and the influence on the strength of the side wall is larger.
In addition, the sealing connection surface of the existing cabin door and the vehicle body is an arc-shaped surface, and the sealing connection surface of the tunnel door and the vacuum pipeline is also an arc-shaped surface, because the vehicle body and the vacuum pipeline are of arc-shaped structures mostly, the sealing performance is poor, the sealing difficulty is increased, and the sealing structure is complex.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide the vacuum train gas-barrier access system with high space utilization rate and good sealing performance.
The technical scheme of the invention is as follows:
the invention relates to a vacuum train gas-barrier access system, which comprises a vacuum pipeline and a vehicle body positioned in the vacuum pipeline; the cabin door and the tunnel door are corresponding and are respectively positioned at the bottoms of the vehicle body and the vacuum pipeline.
The scheme has the following advantages: the cabin door is arranged at the bottom of the vehicle body and the tunnel door is arranged at the bottom of the vacuum pipeline, firstly, more space can be reserved for the side surface of the vehicle body to arrange driving/suspending components such as driving wheels, guide magnets and the like, so that the side surface space utilization rate of the vehicle body is greatly improved; second, the strength of the side wall of the vehicle body can be effectively ensured.
Further, a telescopic air isolation device used for isolating from the vacuum in the vacuum pipeline is arranged between the vehicle body and the inlet and outlet of the vacuum pipeline.
The telescopic air isolation device mainly plays an air isolation role and generally comprises a first fixed part and a telescopic part which stretches along the first fixed part; the first fixing part can be connected with the inlet and outlet of the vehicle body or the vacuum pipeline, and can also be arranged at the periphery of the inlet and outlet of the vehicle body or the vacuum pipeline; if the first fixing part is connected with the vehicle body, the telescopic part is connected with the vacuum pipeline in a sealing way after extending out, if the front end of the telescopic part is matched with the shape of the vacuum pipeline, the sealing is realized; and a second fixing part is arranged on the vacuum pipeline, and the front end of the telescopic part is matched with the shape of the second fixing part, so that sealing is realized. If the first fixing portion is connected with the vacuum pipe, the telescopic portion is connected with the vehicle body in a sealing manner after being extended, and the sealing connection structure can be the same as that described above. The telescopic part can move along the inner cavity of the first fixing part and also can move along the outer wall of the first fixing part. By the telescopic air isolation device, people can ensure that the vacuum state in the vacuum pipeline is still kept and leakage is avoided when getting on or off the vehicle; on the other hand, the inlet channel is consistent with the external air pressure, so that the safety of passengers is ensured. When the getting on/off is finished, the telescopic part can be retracted without influencing the running of the vehicle body.
The entrance and exit of the car body are the entrance and exit corresponding to the cabin door; the inlet and outlet of the vacuum pipeline are the inlet and outlet corresponding to the tunnel gate.
Further, the sealing connection surface of the cabin door and the vehicle body is a plane, and the sealing connection surface of the tunnel door and the vacuum pipeline is a plane.
Because the wallboard of current automobile body and vacuum conduit is the arcwall face, sets up the hatch door on the arc door, also is arc structure basically, even the arc junction surface of hatch door matches with the shape of the arcwall face of automobile body, but the connection between the connection opposite plane of two arcwall faces still is poor to the leakproofness, and this is very strict to the leakproofness requirement, improves the sealing degree of difficulty greatly. The sealing connection surfaces of the cabin door and the tunnel door are both plane, so that the sealing performance can be greatly improved, the entrance and the exit of the vehicle body can be opened to be larger, and if the connection is of an arc-shaped surface, the entrance and the exit are opened to be larger, so that the sealing performance is poorer.
The sealing connection surface of the cabin door and the tunnel door of the invention is a plane, and other surfaces can be plane or curved surfaces, and the sealing connection surface is not particularly limited herein. The sealing connection surface of the vehicle body and the cabin door can be a connecting piece arranged at the entrance and the exit of the vehicle body, and the surface of the connecting piece connected with the cabin door is a plane. If the first fixing part of the telescopic air isolation device is arranged on the vehicle body, the first fixing part can be connected with the cabin door, and the connecting surface is designed to be a plane. The vacuum pipe and the tunnel gate can be connected in the above manner. In addition, the vehicle body and the vacuum pipeline can be arranged into a plane structure, so that the vehicle body and the vacuum pipeline can be directly connected with the cabin door and the tunnel door in a sealing way.
Preferably, the cabin door is arranged on the upper side or the lower side of the bottom of the vehicle body, and if the cabin door is arranged on the upper side, a part of the bottom of the vehicle body, which is connected with the cabin door, is a pit; if the cabin door is arranged at the lower side, the bottom of the vehicle body and the cabin door form a protruding structure. Similarly, the tunnel door is arranged on the upper side or the lower side, preferably the lower side, of the bottom of the vacuum pipeline, so that the tunnel door does not occupy the inner space of the vacuum pipeline.
Further, a pedestrian passageway is arranged between the entrance and the exit of the vehicle body and the ground. Because the car body is at a certain distance from the vacuum pipeline and the vacuum pipeline is at a certain distance from the ground, a pedestrian passageway is required to assist passengers to walk to the ground. The manway may be a staircase, an elevator, a slide or the like. One end of the pedestrian passageway can be directly connected with the inside of the vehicle body, the entrance or the periphery of the entrance, can be connected with the inner wall of the vacuum pipeline, can be directly suspended without being connected, and the bottom of the pedestrian passageway is fixed with the ground and supported by the ladder columns. At least one side of the pedestrian passageway is provided with a handrail for preventing passengers from falling from a high place. If one end of the pedestrian passageway is connected with the inside of the vehicle body, the entrance or the periphery of the entrance, the connected section can be retracted, for example, by overturning and retracting, and the other sections are fixedly connected; thus, when the stairs are far away from the entrance and the exit of the car body, the distance can be shortened by putting down the section which can be turned over; and after the cabin is completely accessed, the operation of the vehicle body can not be influenced by retracting the cabin. In addition, the pedestrian passageway can be integrally designed into a rotatable and retractable structure, such as a telescopic ladder, a folding ladder and the like, so that the space is saved.
Further, the pedestrian passageway comprises two parts, wherein one part is arranged between the vehicle body and the inlet and outlet of the vacuum pipeline, and the other part is arranged between the inlet and outlet of the vacuum pipeline and the ground. Wherein, the part of the pedestrian passageway arranged between the vehicle body and the inlet and outlet of the vacuum pipeline is positioned in the air isolation space so as to ensure personal safety.
Preferably, the telescopic air isolation device comprises an air isolation groove, one end of the air isolation groove is connected with a telescopic air isolation cover, and the air isolation cover selectively extends out and is in sealing connection with an air isolation chamber of the vacuum pipeline to form an isolation space. The air isolation cover is telescopic along the air isolation groove and is connected with the air isolation chamber in a sealing way after extending out, so that an air isolation space is formed, and passengers can get on or off the vehicle conveniently. The air isolation chamber is preferably arranged on the vacuum pipeline instead of the vehicle body, so that the movement of the vehicle body is not hindered, on the other hand, the control by personnel in the train is facilitated, and compared with the control by personnel outside, the air isolation chamber can enable the personnel in the train to quickly move the air isolation cover, and the efficiency is improved; but also can save personnel configuration.
Preferably, the side surfaces of the air-isolation cover and the vehicle body are planes, and the sealing connection surface of the air-isolation cover and the air-isolation chamber is a plane. In the invention, the first sealing piece is arranged at the joint of the air-isolation cover and the vehicle body and is in plane sealing, so that the sealing performance is greatly improved, and when the air-isolation cover moves along the vehicle body, the vacuum isolation with the vacuum pipeline is realized by compressing the sealing piece. The connecting surface of the end face of the gas-barrier cover and the gas-barrier chamber is also a plane, so that the plane tightness is better, and the second sealing piece is arranged on the tail end of the gas-barrier cover, so that the tail end and the gas-barrier chamber are tightly pressed and sealed. The invention does not limit the specific structure of the sealing element, and can only play a role in sealing, for example, the first sealing element is preferably an elastic sealing element, a groove can be formed on the connecting surface of the vehicle body, the elastic sealing element is arranged in the groove, and sealing is realized by compressing the elastic sealing element.
Further, the air isolation groove is arranged at the position of an inlet and outlet of the vehicle body or the vacuum pipeline, and a driving device for driving the air isolation cover to stretch and retract is arranged in the vehicle body.
The movement of the gas barrier cover is controlled by personnel in the train, and compared with the control by external personnel, on one hand, the personnel in the train can quickly move the gas barrier cover, so that the efficiency is improved; on the other hand, personnel configuration can be saved. The driving device is a push-pull part and plays roles of pushing outwards and pulling inwards, is connected with the gas shield by pushing out, and then drives the gas shield to move so as to realize expansion. The push-pull part can be at least one push-pull rod, and can also be other structures with a push-pull function, and the invention is not limited in particular. The end of the push-pull part can be directly and fixedly connected with the gas shield, and can also be selectively and adaptively connected with the gas shield. The selective adapting connection can be at least one connection mode of lock catch connection, hook-pull connection, magnetic connection, suction connection, scarf joint, sleeve joint and the like.
The push-pull part can be pushed and pulled manually, electrically, hydraulically or pneumatically. The manual mode can be that a person in the vehicle holds the handle to control the mechanical structure to drive the push-pull part to push and pull, and the mechanical structure can be a worm gear, a gear combination and the like. And the structure is complex by adopting an electric, hydraulic or pneumatic mode compared with a manual mode, but the labor is saved.
Further, a floor is arranged in the vehicle body, and a floor door is arranged on the floor. In general, when a passenger walks on a floor in a vehicle, a floor door needs to be provided at a position opposite to a cabin door, so that, compared with the case of providing a single cabin door, the floor can increase the walking space of the passenger in the vehicle, and on the other hand, the floor is provided above the cabin door, so that double sealing can be performed, and the safety factor of the passenger can be improved. The ground door can be opened in a movable mode or can be pulled upwards by a handle.
Further, the hatch and tunnel door are opened or closed by water translation movement. If the cabin door is pulled out upwards, then horizontally moving and opening the cabin door; or pushing the tunnel gate downwards and then horizontally moving the tunnel gate to open.
Further, the cabin door and/or the tunnel door are/is provided with a device for balancing the internal pressure and the external pressure. The device can be a valve, an air extraction system and the like so as to ensure that the pressure in the air isolation channel is consistent with the pressure in the vehicle when the passenger leaves the cabin; after the passengers enter the cabin, the interior of the air isolation channel is vacuumized, and then the telescopic part of the telescopic air isolation device is retracted.
The invention relates to another vacuum train gas-insulated access system, which comprises a vacuum pipeline and a train body positioned in the vacuum pipeline; the cabin door and the tunnel door are corresponding and are respectively positioned at the tops of the vehicle body and the vacuum pipeline.
The scheme has the following advantages: the cabin door is arranged at the top of the vehicle body, and the tunnel door is arranged at the top of the vacuum pipeline, so that more space can be reserved for the side surface and the bottom of the vehicle body to arrange driving/suspending components, such as driving wheels, guide magnets and the like, and the space utilization rate of the side surface and the bottom of the vehicle body is greatly improved; secondly, the vacuum pipeline is arranged at the top, and can be arranged at a high place without being erected, so that the application range is wider; thirdly, the top of the existing vacuum train is usually provided with an escape opening, and the cabin door and the tunnel door are arranged on the side face, so that the cabin door and the tunnel door are arranged on the top, the escape opening is not required, and the structure is greatly simplified; fourth, the strength of the side wall of the vehicle body can be effectively protected.
