Description

Technical Field

For conventional double-leaf platform door systems, the door opening position is often fixed and the door opening range is limited. It is usually only applicable to rail transit forms with certain vehicle types such as light rail and subway. It is often not perfectly applicable to rail transit forms with more vehicle types. For this reason, researchers began to focus on platform door systems with stronger adaptability and larger door opening range to meet the increasingly stringent application needs of platform doors. The lifting platform door came into being under this opportunity.

[0068] Example:

[0069] See also Figure 1 to Figure 18 The quick-installed lifting platform door system with an emergency evacuation door in the preferred embodiment of the present invention comprises two lifting columns spaced apart in the longitudinal direction and a platform door unit extending in the longitudinal direction between the two lifting columns. At the same time, each lifting column is respectively configured as a column-type chassis structure, in which a vertical lifting structure and a platform door connecting assembly corresponding to the lifting part of the vertical lifting structure are arranged. By connecting the longitudinal ends of the platform door unit to the platform door connecting assembly on the corresponding lifting column, the corresponding setting of the platform door unit can be achieved. Then, the vertical lifting structures of the two lifting columns work simultaneously, so that the lifting and lowering control of the platform door unit can be achieved.

[0070] For the platform door unit in the preferred embodiment, it is preferably assembled from multiple modules, and an openable and closable emergency door is formed in the middle of the platform door unit, so that when the vertical lifting structure of the two lifting columns fails, the emergency door can be opened to connect the two lateral sides of the platform door unit, making it convenient for train passengers in the track area to get off and passengers on the platform layer to get on, thereby ensuring the safe operation of the lifting platform door system.

[0071] Specifically, the lift platform door system in the preferred embodiment is as follows Figure 1 , Figure 2 As shown in , it includes two lifting columns spaced apart in the longitudinal direction (the direction of rail transit operation), namely Figure 1 The first chassis module 1 and the second chassis module 7 shown in the figure are respectively arranged vertically and form a space for assembling the platform door unit therebetween.

[0072] In the preferred embodiment, the structure of the lifting column is introduced by taking the first chassis module 1 as an example, and the structure of the second chassis module 7 is similar.

[0073] The first chassis module 1 includes a chassis shell 101 extending vertically, and a space for accommodating the lifting assembly and the platform door connecting assembly is formed inside the chassis shell 101. At the same time, the chassis shell 101 in the preferred embodiment is connected and fixed to the platform floor through a plurality of connecting members 10, and the aforementioned connecting members 10 are further preferably connecting bolts.

[0074] At the same time, in a preferred embodiment, the lifting assembly is further preferably a spiral screw assembly, which includes a transmission rod 103 arranged vertically and a transmission cylinder 104 spirally matched and sleeved on the outer periphery of the transmission rod 103. Correspondingly, a driving motor 102 is provided corresponding to the transmission rod 103, which is preferably arranged at the bottom of the chassis shell 101 and is further specifically fixed to the ground. By connecting the bottom end of the transmission rod 103 with the output end of the driving motor 102, and movably connecting the top of the transmission rod 103 with the top of the chassis shell 101 with a bearing seat, the driving motor 102 can correspondingly drive the transmission rod 103 to rotate forward or reverse, thereby driving the transmission cylinder 104 to perform vertical lifting movement.

[0075] Furthermore, the platform door connection assembly in the preferred embodiment is connected to one side of the transmission cylinder 104, specifically, to the side of the transmission cylinder 104 facing another lifting column, that is, the longitudinal side. The platform door connection assembly includes a first connection handle 105 extending horizontally and fixedly connected to the top of the transmission cylinder 104, and an elastic guide rail 110 arranged below the first connection handle 105 and extending vertically; accordingly, a second connection handle 109 extending horizontally is also arranged below the first connection handle 105, and the second connection handle 109 is arranged parallel to the first connection handle 105, and one end of the second connection handle 109 matches the elastic guide rail 110, and can perform vertical reciprocating motion under the guidance of the elastic guide rail 110, approaching or moving away from the first connection handle 105.

[0076] In actual configuration, a lifting mechanism is provided corresponding to the second connecting handle 109 to drive the second connecting handle 109 to reciprocate vertically.

[0077] In more detail, the lifting mechanism is arranged between the two connecting handles, and includes a first screw rod 106 and a second screw rod 108 which are coaxially arranged. The top of the first screw rod 106 is connected to the first connecting handle 105, and the bottom of the second screw rod 108 is connected to the second connecting handle 109. The rotation directions of the two screw rods are opposite, and a spiral elastic cylinder 107 is arranged at the free ends of the two screw rods. An internal thread is formed inside the spiral elastic cylinder 107, and the internal threads at both ends thereof rotate in opposite directions. After the spiral elastic cylinder 107 is matched with the threads of the two screw rods, the two screw rods can be moved closer or farther away by rotating the spiral elastic cylinder 107, that is, the second connecting handle 109 can be vertically lifted relative to the first connecting handle 105.

[0078] In actual configuration, it is preferred to provide an auxiliary rotation mechanism on the outer periphery of the spiral elastic tube 107, for example, a mesh pattern for increasing friction is provided on the outer periphery of the spiral elastic tube 107, or the cross-sectional shape of the spiral elastic tube 107 is set to a polygon, such as a hexagon or a pentagon, to facilitate the matching and rotation of mechanisms such as a wrench. Of course, the design for auxiliary rotation can also be preferably in other forms as needed, which will not be elaborated here.

[0079] Further preferably, in order to save the number of lifting columns and realize the synchronous control of the platform door unit, in the preferred embodiment, platform door connecting components are respectively arranged on both sides of the longitudinal direction of the transmission cylinder 104, such as Figure 3 , Figure 4 As shown in , it is connected to another platform door unit on the other longitudinal side of the lifting column. At this time, the two sets of platform door connection components are symmetrically arranged with the axis of the transmission cylinder 104, and can realize synchronous movement under the drive of the transmission cylinder 104.

[0080] Of course, in actual settings, considering that the corresponding platform door unit may need to be controlled separately, or the platform door unit is at the edge of the platform in the longitudinal direction, at this time, only one set of platform door connection components may be set in at least some of the lifting columns.

[0081] Furthermore, if Figure 5~Figure 9 As shown in the figure, the platform door unit in the preferred embodiment is composed of a plurality of modularly prepared door body units connected to each other, wherein at least one emergency door unit and a pair of assembly door units are included, and the door body units are assembled and connected to each other to form an integrated platform door unit structure.

[0082] In a preferred embodiment, the emergency door unit is preferably a pair, that is, the platform door unit preferably includes a first assembly door unit 2 , a second assembly door unit 6 , a first emergency door unit 3 and a second emergency door unit 5 .

[0083] In actual configuration, the two assembly door units are disposed at the longitudinal ends of the platform door unit, and are used to be connected and assembled with the platform door connection assembly. The two assembly door units preferably have the same structure, and the preferred embodiment is described by taking the first assembly door unit 2 as an example.

[0084] Specifically, in the preferred embodiment, the first assembly door unit 2 is a plate-like structure, and a pair of hanging shafts are arranged on one side, namely, a first hanging shaft 202 and a second hanging shaft 203 arranged below the first hanging shaft 202. The two hanging shafts are L-shaped structures, one end of which is horizontally connected to the side wall surface of the assembly door unit, and the other end extends vertically, and the vertically extended ends of the two hanging shafts are arranged opposite to each other, such as Figure 3 as shown in .

[0085] Correspondingly, the ends of the two connecting handles in the platform door connecting assembly are respectively provided with connecting holes in the vertical direction. The two connecting holes are opened on the sides of the two connecting handles facing away from each other, and are further preferably through holes for embedding the free ends of the two hanging shafts.

[0086] In actual setting, the door unit can be initially assembled by coaxially inserting the free end of the first hanging shaft 202 into the connecting hole at the end of the first connecting handle 105. After that, the vertical position of the second connecting handle 109 can be controlled by the spiral elastic cylinder 107, so that the free end of the second hanging shaft 203 can be inserted into the connecting hole at the end of the second connecting handle 109, thereby realizing the rapid assembly of the door unit on the lifting column. Figure 4 as shown in .

[0087] At the same time, in order to ensure the accuracy of connection and movement of the assembled door unit, in a preferred embodiment, a limit assembly is provided at the end of at least one connecting handle to limit the rotation range of the assembled door unit.

[0088] Specifically, the limit assembly includes a parallel baffle 111 and a vertical baffle 112 arranged orthogonally, the former is arranged parallel to the extension direction of the track area, that is, arranged in the longitudinal direction, and the latter is arranged transversely along the track area, perpendicular to the longitudinal direction of the track, such as Figure 5 , Figure 6 As shown in . The two baffles are arranged corresponding to the connection hole at the end of the connection handle, the parallel baffle 111 is arranged on the side of the connection hole close to the track area, and the vertical baffle 112 is arranged on the side of the connection hole away from the platform door unit. With the corresponding arrangement of the two baffles, the assembled door unit can rotate within a range of 90° and effectively prevent the assembled door unit from rotating into the track area.

[0089] By utilizing the above-mentioned combination arrangement of the platform door connection assembly and the paired hanging shafts, the assembly process of the platform door can be greatly simplified, the efficiency of the assembly and replacement of the platform door units can be improved, and it can be ensured that the assembly and installation process affects the normal operation of rail transit as little as possible.

[0090] Preferably, in order to reduce the deadweight of the platform door unit, the assembled door unit in the preferred embodiment preferably includes an assembled door frame 201 and a lightweight baffle disposed in the assembled door frame 201, and the lightweight baffle is further preferably a first baffle 204 made of tempered glass.

[0091] Of course, it is understood that, according to the actual setting requirements, the first baffle 204 can also be replaced with other materials, or even set as a display screen or an advertising display frame, etc., which will not be described in detail here. Similarly, the assembly door frame 201 in the preferred embodiment can also be preferably made of a light material with greater strength, such as titanium alloy, aluminum alloy, etc.

[0092] Similarly, the main structure of the emergency door unit in the preferred embodiment is preferably the same as or similar to the main structure of the assembly door unit, that is, it includes an emergency door frame 301 and a second baffle 303 disposed in the door frame. At the same time, the emergency door unit in the preferred embodiment is preferably rotatably connected to the assembly door unit by a plurality of hinges, such as Figure 7As shown in the figure, the first hinge 206 and the second hinge 207 are arranged at a vertical interval, and the two hinges are preferably connected to the side of the two-unit door frame close to the track area, to ensure that the emergency door unit can only be pushed open to the platform side, to avoid part of the platform door unit extending into the track area, affecting the operational safety in the track area.

[0093] More specifically, in order to achieve reliability in matching the emergency door unit and the assembly door unit, a magnetic suction assembly is provided on the connecting ends of the two units to ensure that the connecting ends of the two units can be reliably connected to form an integral structure when the platform door unit is operating normally.

[0094] In actual configuration, the magnetic attraction components are preferably configured as at least one pair, for example Figure 7 As shown in the figure, the two pairs of magnets, namely the first upper magnet 205 and the second upper magnet 304, and the first lower magnet 208 and the second lower magnet 305, which are arranged at the upper and lower ends of the unit, utilize the opposite attraction of the upper and lower groups of magnets to ensure the reliability of the assembly connection between the emergency door unit and the corresponding assembled door unit, and ensure that the two units are aligned in the longitudinal direction under normal working conditions to form an integrated door body structure.

[0095] Furthermore, the main structures of the two emergency door units (the first emergency door unit 3 and the second emergency door unit 5) are the same, namely, they respectively include an emergency door frame 301 and a second baffle 303, which will not be described in detail herein.

[0096] At the same time, the two emergency door units are correspondingly arranged on one side away from the assembled door units to which they are respectively (directly or indirectly) connected, and locking grooves are provided in pairs at the opposite ends of the two emergency door units, and locking components that can reciprocate in the longitudinal direction are provided corresponding to the two locking grooves, so that the two emergency door units can be locked by the locking components after the ends are aligned to form an integral door body structure, and after the locking components move in the longitudinal direction, the locking state between the two emergency door units can be correspondingly released, and at this time, the emergency door unit can be correspondingly opened.

[0097] Of course, it can be understood that when the emergency door unit is set to one, the locking groove originally opened on one of the emergency door units and coaxially corresponding to the locking groove of the other emergency door unit can be correspondingly opened on the door body unit that is docked with the end of the only remaining emergency door unit, such as the end of the assembly door unit docked with it.

[0098] In actual configuration, at least one set of locking grooves is provided at the ends of the two emergency door frames 301, for example Figure 8 , Fig. 9 Two pairs of locking grooves are arranged on the upper and lower sides of the emergency door unit, and each locking groove extends along the extension direction of the panel of the emergency door unit, and is correspondingly provided with the following Figure 8 , Fig. 9The serially connected sliding lock assembly 4 shown in the figure is used as a locking assembly to complete the locking and unlocking control after the ends of the two emergency door units are butted together.

[0099] Furthermore, a sliding groove is arranged in the longitudinal direction in the locking groove of one of the emergency door units, for example, a first sliding groove 501 and a second sliding groove 502 are arranged in the upper and lower locking grooves of the second emergency door unit 5 in the preferred embodiment, and sliding locking rods are coaxially embedded in the two locking grooves, namely the first sliding locking rod 401 and the second sliding locking rod 403. The two sliding locking rods are arranged in parallel and can be synchronously moved back and forth in the longitudinal direction, so that the end of the sliding locking rod can extend into the locking groove at the end of the first emergency door unit 3 or extend therefrom.

[0100] In the actual setting, in order to ensure the synchronous driving of the two sliding locking rods, a handle extending vertically is arranged in series between the two sliding locking rods, and connecting holes are respectively opened in the middle of the two sliding locking rods, so that the two ends of the handle can be connected to the corresponding connecting holes through the connecting parts (i.e., the first connecting part 404 and the second connecting part 405) passing through the first sliding groove 501 and the second sliding groove 502.

[0101] In a specific preferred embodiment, the handle connecting the two sliding lock rods is a movable handle, both ends of which pass through two slide grooves and are movably connected to the two sliding lock rods, so that it can be moved back and forth in a direction perpendicular to the platform door unit.

[0102] More specifically, the movable handle is further preferably a magnetic handle 402, such as Figure 8~Figure 11 As shown in , at this time, the two connecting parts and the magnetic handle 402 form an integral structure, that is, Fig.10 The "C-shaped" structure shown in the figure, and the ends of the two connecting parts pass through the corresponding slide grooves and are movably connected to the connecting holes, so that it can reciprocate a certain distance in the direction perpendicular to the platform door unit, thereby realizing the pulling out or sticking of the magnetic handle 402 relative to the emergency door unit.

[0103] Correspondingly, a vertically extending embedding groove is provided at the locking position of the locking assembly corresponding to the magnetic handle 402. In actual setting, the embedding groove can be provided on the door frame of the second emergency door unit 5, or between the ends of the two emergency door units. Fig. 9 At this time, the two slide grooves are connected to the end of the second emergency door unit 5. In addition, in order to facilitate the magnetic handle 402 to be pulled out from the handle hidden groove 504, a groove is provided on at least one side of the handle hidden groove 504, such as Figure 8 The first groove 302 and the second groove 503 shown in the figure enable the operator to quickly pull out the magnetic handle 402 from the two grooves.

[0104] Preferably, in order to ensure the reliability of embedding the magnetic handle 402 , a magnetic unit is provided in the handle hidden groove 504 in a preferred embodiment, which is used to match the magnetic handle 402 and reliably adsorb it in the handle hidden groove 504 .

[0105] Further preferably, the movable handle may also be preferably in another form. For example, in another preferred embodiment, the connecting parts at both ends thereof are respectively connected to the sliding lock rod by elastic members, and the elastic members may preferably be springs. The two elastic members are arranged so that the two connecting parts exert a force that is always directed to the platform door unit, so that the movable handle is reliably locked in the handle hidden groove 504, and the abutment between the movable handle and the side wall of the handle hidden groove 504 completes the axial limitation of the sliding lock rod, and the two emergency door units in the normal working state are locked in the connected state. When it is necessary to unlock the two emergency door units, it is only necessary to manually pull out the movable handle and slide it to the side away from the first emergency door unit 3 to unlock it.

[0106] As another embodiment of the present invention, in another specific embodiment, the handle connecting the two sliding lock rods is a fixed handle, and its two ends respectively pass through the corresponding sliding grooves through the connecting parts and are fixedly connected to the sliding lock rod. Correspondingly, an elastic member is provided in at least one locking groove corresponding to the sliding lock rod, for example, a first tension spring 511 and a second tension spring 512 are respectively provided in the two locking grooves in the second emergency door unit 5, one end of the two tension springs is fixed in the locking groove, and the other end is connected to the end of the corresponding sliding lock rod, so that the two sliding lock rods can always bear a force pointing away from the locking groove on the first emergency door unit 3 under the action of the two tension springs. In this way, once the locking of the two sliding lock rods is released, the two sliding lock rods can be automatically pulled away from the first emergency door unit 3 by the two tension springs, thereby realizing the unlocking of the two emergency door units.

[0107] Due to the setting of the fixed handle, the two emergency door units always move synchronously, and the operating personnel can also pull the two emergency door units in the unlocked state to the locked position through the fixed handle.

[0108] Furthermore, a limiting assembly is correspondingly arranged in the door body frame of one of the emergency door units, which includes a pair of toothed locking rods, namely a first toothed locking rod 506 and a second toothed locking rod 509, and corresponding to the two toothed locking rods are respectively provided with lock cylinders, namely a first lock cylinder 505 and a second lock cylinder 510. The two lock cylinders are fixedly arranged in the door body frame, and the two are respectively arranged vertically. The two toothed locking rods are coaxially embedded in the corresponding lock cylinders and can be vertically lifted and lowered under the guidance of the lock cylinders.

[0109] In more detail, a rotating gear 508 is provided at the two ends of the two toothed locking rods, and racks are provided at the ends of the two toothed locking rods, which are arranged on both longitudinal sides of the rotating gear 508 and are respectively engaged with the rotating gear 508, so that the rotating gear 508 can synchronously drive the two toothed locking rods to move by rotating, approaching or moving away from each other.

[0110] Correspondingly, at least one pair of locking holes is provided on opposite sides of the two sliding locking rods, for example Fig.13 The first locking hole 406 and the second locking hole 407 shown in the figure enable the ends of the two toothed locking rods to be vertically aligned with the corresponding locking holes respectively after the two sliding locking rods are locked in place, and then the two toothed locking rods can be embedded and locked in the corresponding locking holes through the rotation control of the rotating gear 508.

[0111] In actual setting, a rotating handle 507 is provided corresponding to the rotation drive of the rotating gear 508 , and the driving control of the rotating gear 508 can be achieved by rotating the rotating handle 507 .

[0112] Furthermore, in actual settings, the handle and rotating gear 508 are preferably arranged on the side of the platform door unit close to the track area to ensure that the door can be quickly opened from this side during emergency parking to ensure the accuracy of emergency evacuation. Of course, according to the needs of actual settings, a corresponding quick unlocking structure can also be provided for the serial sliding lock assembly 4 on the side close to the platform to ensure the reliability and safety of the platform door system.

[0113] As another specific embodiment of the present invention, in actual settings, at least one transition door unit is further provided between the emergency door unit and the corresponding assembly door unit, which is rotatably connected to adjacent units (assembly door unit / emergency door unit / transition door unit) by hinges, thereby correspondingly increasing the adjustment flexibility of the setting length of the platform door unit.

[0114] Of course, according to the actual setting needs, the emergency door unit and / or the assembly door unit can be set to different specifications (different lengths / different heights) and the size specifications of the platform door unit can be changed by replacing the corresponding units.

[0115] In addition, in actual settings, two adjacent platform door units can be driven independently or synchronously. When driven independently, the longitudinal ends of the platform door unit are matched with independent lifting columns respectively, while when driven synchronously, the two adjacent platform door units share the same lifting column, and the longitudinal sides of the transmission cylinder 104 in the lifting column are respectively provided with platform door connection components. Through the drive of a driving motor 102, the synchronous drive of the two platform door connection components can be realized, thereby realizing the synchronous lifting control of the two adjacent platform door units.

[0116] In a preferred embodiment, at least some of the plurality of lift platform door units located on the same platform are driven synchronously, and at least some of the platform door units are driven independently.

[0117] Further preferably, a door beam 8 is provided at the top of the two lifting columns along the longitudinal extension, which includes a door beam shell 801 in a square tube structure. The door beam shell 801 is hollow inside and can be used as a laying space for related cables. The two ends of the door beam shell 801 are respectively connected to the top of the corresponding lifting columns, that is, respectively connected to the chassis shells 101 of the two chassis modules, and are further specifically connected and fixed by through bolts 802, such as Fig.15 As shown in , the two lifting columns and the door beam 8 are combined to form a "door-type" structure, and the integral door frame structure ensures the stability and safety of the entire platform door system.

[0118] As a further preferred embodiment of the present invention, a transmission harness module 9 is provided on the formed integral door frame structure. Fig.16 As shown in , it includes a plurality of wire harnesses 901 laid in the door beam shell 801. Corresponding to the fixation of each wire harness 901, a wire harness fixing seat 903 is preferably provided on the door beam shell 801, and a plurality of wire harness sockets 902 are provided corresponding to the plugging of each wire harness 901. Correspondingly, at least one connecting wire harness module 11 is also provided, which is provided at the connection part between the lifting column and the door beam 8, and is used for the connection and conduction between different transmission wire harness modules 9; at this time, the wire harness socket 902 is preferably provided on the connecting wire harness module 11.

[0119] By arranging the transmission harness module 9 in the door beam 8, the related cables of the platform door system do not need to be laid in grooves on the platform, which saves civil engineering costs and further improves the aesthetics of the platform door system.

[0120] For the quick-install lift platform door system in the preferred embodiment, its working and emergency procedures preferably include the following steps:

[0121] (1) Before the train enters the station, the quick-install lift platform door system with emergency doors is in a blocked state. Figure 1 As shown, looking down Fig.17 As shown;

[0122] (2) After the train door opens, the quick-install lift platform door system with emergency door moves from the blocking state to the pass state. Figure 2 As shown;

[0123] (3) After the doors are closed before the train leaves the station, the quick-install lifting platform door system with emergency doors moves from the pass state to the blocking state. Figure 1 As shown, looking down Fig.17 As shown;

[0124] (4) When the platform door drive mechanism fails and cannot raise or lower the door normally, passengers can unlock the emergency door, push the emergency door to drive the hanging door to rotate 90° toward the platform side, and continue to push the emergency door to overcome the magnetic attraction between the emergency door unit and the assembly door unit. The emergency door unit rotates a certain angle under the action of the hinge, and the entire door body opens, allowing passengers to get on and off the train normally. Fig.18 As shown;

[0125] (5) After the platform door drive fault is eliminated, follow the reverse steps of opening the emergency door unit in (4) to splice all door modules into a complete door body and restore the normal operation of the lift platform door system.

[0126] The quick-installation lifting platform door system with emergency evacuation door in the present invention has a compact structure and is easy to assemble. It can realize the rapid assembly of the lifting platform door and can form an openable and closable emergency door on the platform door unit after assembly, ensuring that the emergency door unit can achieve communication between the train and the platform through the rapid opening of the emergency door when all its lifting control functions fail, enabling passengers to get on and off the train, avoiding the impact of functional failures of the lifting platform door system on the normal operation plan of the train, and fully ensuring the reliability and safety of emergency evacuation of the train, and has excellent practical value and application prospects.

[0127] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
