Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicle gangways, and in particular to a ferry plate turning device, a gangway assembly and a rail vehicle. Background Art

[0002] With the rapid development of the railway industry, high-speed railways, intelligent intercity railways, and unmanned subways have been widely used. Automatic train driving and the automatic coupling and uncoupling of external components between carriages have also developed accordingly. To adapt to automatic driving and rapid automatic coupling and uncoupling, the gangway, a key component of the train, needs to develop corresponding automatic coupling and uncoupling functions, which can be achieved through electric or pneumatic control. Currently, there is no application of automatic coupling and uncoupling gangways in the existing technology. It is imperative to propose a new type of high-efficiency automatic docking windshield that does not require manual labor and reduces time costs.

[0003] The automatic docking windshield has two main functions: the first is to fix the windshields to the bellows of two adjacent carriages, and to connect and unlock the two windshields by locking and unlocking the locking rods in their respective frames; the second is to automatically connect and unlock the load-bearing channel after the bellows are connected, serving as a safe passage for passengers. The existing rapid-disconnect windshield ferry has no automatic flipping function and is a purely mechanical installation. When rapid connection and disconnection is required, the ferry must be manually separated and retracted. The commonly used windshield connection and disconnection method only separates the ferry from the adjacent pedals, and cannot be retracted or fixed. In the requirements of automatic docking windshields, after the two carriages are separated, one side needs to be separated with the ferry and the door on the same side is closed. In this way, the ferry needs to be flipped, retracted and fixed to ensure that the extension distance of the ferry is reduced and the door is closed normally. Without automatic flipping, the ferry will need to be manually flipped at the apron of each carriage of a long train, wasting a lot of manpower and time. This is uneconomical and does not meet the requirements of automatic driving trains. Therefore, it is a very necessary topic to retract and fix the extended ferry and close the door normally in the extremely short time when the carriages can be separated.

[0004] In summary, the ferry boards in the existing technology are all mechanically installed on the car body, and the flipping of the ferry boards of each car needs to be manually adjusted. For long-formation vehicles, when it comes to situations such as automatic docking of windshields and rapid undocking of windshields, there is a problem that fast and automatic flipping cannot be achieved. Summary of the Invention

[0005] The present invention provides a ferry plate flipping device, a gangway assembly and a rail vehicle, which are used to solve the defect that the ferry plates in the gangway assembly in the prior art are all flipped manually and cannot be automatically flipped, resulting in a large amount of manpower and time being consumed, and reducing the work efficiency of windshield uncoupling and coupling.

DETAILED DESCRIPTION

[0046] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0051] The following combination Figures 1 to 6 The present invention describes a ferry turning device, which specifically includes: a vehicle body connecting frame 201 , a ferry body 202 , a driving mechanism 204 and a locking rod 205 .

[0052] Specifically, the ferry board body 202 is rotatably connected to the vehicle body connection frame 201; the driving mechanism 204 is arranged on the vehicle body connection frame 201; one end of the locking rod 205 is connected to the driving mechanism 204, and the other end of the locking rod 205 can be connected to the ferry board body 202. The driving mechanism 204 drives the locking rod 205 to move along the height direction of the vehicle body connection frame 201 to achieve the purpose of driving the ferry board body 202 to flip.

[0053] In this embodiment, the ferry body 202 is mounted on the vehicle body connection frame 201 via a rotating shaft 203, and can be rotated via the rotating shaft 203. The driving mechanism 204 acts as the driving force for the rotation of the ferry body 202, driving the locking rod 205 to move in the height direction. The movement of the locking rod 205 drives the rotating shaft 203 to rotate, thereby driving the ferry body 202 to rotate. It should be understood that the linear movement of the locking rod 205 can be converted into rotational motion of the rotating shaft 203 by a transmission mechanism, including a gear 211 and a rack 209 or a lead screw.

[0054] When the bellows docking frame 114 is extended into place, the pedal 130 is also extended, the driving mechanism 204 drives the locking rod 205 to move, the rotating shaft 203 rotates, and the ferry body 202 rotates synchronously from a vertical state to a horizontal state and overlaps the pedal 130; when the bellows needs to be recovered, the driving mechanism 204 is first controlled to drive the locking rod 205 to move in the opposite direction, the rotating shaft 203 rotates in the opposite direction accordingly, the ferry body 202 rotates in the opposite direction synchronously from a horizontal state to a vertical state, and is lifted from the pedal 130, and then the bellows docking frame 114 and the pedal 130 are recovered to the first carriage.

[0055] Furthermore, in order to ensure the stability of the connection, locking rods 205 are arranged on both sides of the car body connection frame 201, and there are three locking rods 205 on each side. The three locking rods 205 are connected into an integrated structure to ensure the movement uniformity of the locking rods 205; accordingly, locking hooks 117 are also arranged on both sides of the bellows docking frame 114, and there are three locking hooks 117 on each side. The three locking hooks 117 are independently set.

[0056] The present invention provides a ferry board turning device, which includes: a vehicle body connection frame 201, a ferry board body 202, a driving mechanism 204, and a locking rod 205. The ferry board body 202 is rotatably connected to the vehicle body connection frame 201 via a rotating shaft 203. The driving mechanism 204 is disposed on the vehicle body connection frame 201. One end of the locking rod 205 is connected to the driving mechanism 204, and the driving mechanism 204 is used to drive the locking rod 205 to move along the height direction of the vehicle body connection frame 201. The other end of the locking rod 205 can be connected to the rotating shaft 203 to drive the ferry board body 202 to rotate about the rotating shaft 203. In the ferry board turning device provided by the present invention, the driving mechanism 204 acts as a driving force to rotate the rotating shaft 203 via the locking rod 205, thereby realizing the turning of the ferry board body 202 on the vehicle body connection frame 201. When the vehicle body connection frame 201 is coupled or uncoupled, the ferry board is automatically turned instead of manually, thereby reducing manpower waste and working time, and greatly improving work efficiency.

[0057] In one embodiment of the present invention, the ferry board flipping device further includes a transmission mechanism, located at the other end of the locking rod 205. The transmission mechanism is connected to the ferry board body 202 via the rotating shaft 203 to drive the ferry board body 202 to flip about the rotating shaft 203. Preferably, the transmission mechanism includes a rack 209 and a gear 211. The rack 209 is connected to the locking rod 205. The gear 211 is connected to the rotating shaft 203 and is capable of driving the rotating shaft 203 to rotate. The gear 211 can engage with the rack 209. In this embodiment, the transmission mechanism formed by the gear 211 and the rack 209 converts the linear motion of the locking rod 205 into the rotational motion of the rotating shaft 203. It should be understood that only when the gear 211 is engaged with the rack 209 can the movement of the locking rod 205 be converted into the movement of the rotating shaft 203. That is to say, if the locking rod 205 moves to a position where the rack 209 is not engaged with the rack 209, the movement of the locking rod 205 cannot drive the rotating shaft 203 to rotate. By reasonably arranging the engagement relationship between the gear 211 and the rack 209, the problem of excessive flipping of the ferry body 202 can be avoided.

[0058] In one embodiment of the present invention, a locking hole 2051 is formed on the locking rod 205, and a locking hook 117 is provided on the bellows docking frame 114 adjacent to the locking rod 205; when the locking rod 205 drives the ferry body 202 to rotate to the connected state, the locking hook 117 is inserted into the locking hole 2051 and locked; when the locking rod 205 drives the ferry body 202 to rotate to the uncoupled state, the locking hook 117 disengages from the locking hole 2051 and is unlocked. Specifically, the lock hole 2051 is a long strip lock hole 2051 with a baffle above the lock hole 2051. When the lock hook 117 is inserted into the lock hole 2051, the baffle and the lock hook 117 can be engaged by moving the lock rod 205, thereby achieving the locking of the lock hook 117 and the lock rod 205. When the lock hook 117 and the lock rod 205 need to be unlocked, it is only necessary to move the lock rod 205 in the direction of the lock hook 117, and the lock hook 117 can be horizontally moved out of the lock hole 2051 under the drive of the bellows docking frame 114. Figure 8 In the structure shown, when the bellows docking frame 114 moves to fit with the vehicle body connection frame 201, the locking hook 117 is correspondingly inserted into the insertion hole. After the locking rod 205 moves downward, the end of the locking hook 117 is just blocked by the baffle above the locking hole 2051, thereby locking the locking hook 117 and the locking rod 205.

[0059] In one embodiment of the present invention, a guide hole 206 is provided in the vehicle body connection frame 201. The fixed end of the drive mechanism 204 is fixed to one side of the vehicle body connection frame 201, and the movable end of the drive mechanism 204 passes through and moves within the guide hole 206. The movable end of the drive mechanism 204 is connected to a locking rod 205 located on the other side of the vehicle body connection frame 201. In this embodiment, the drive mechanism 204 and the locking rod 205 are respectively located on either side of the vehicle body connection frame 201. The movable end of the drive mechanism 204 can be connected to the locking rod 205 via a connecting rod passing through the guide hole 206. The guide hole 206 is used to limit the movement direction of the locking rod 205, ensuring that the locking rod 205 moves in a vertical direction.

[0060] In one embodiment of the present invention, gear 211 is a quarter-circular gear. When the lock rod 205 drives the ferry body 202 to rotate to the connected state, the quarter-circular gear rotates to one end and engages with the rack 209. When the lock rod 205 drives the ferry body 202 to rotate to the uncoupled state, the quarter-circular gear rotates to the other end and engages with the rack 209. In this embodiment, since the ferry body 202 only rotates 90° (the angle of a quarter circle) during the entire flipping process, the pitch circle of gear 211 is also designed to be a quarter circle. This ensures that when the ferry body 202 is in the horizontal / vertical state, the rack 209 engages with one end of the quarter-circular gear. After the ferry body 202 rotates to the vertical / horizontal state, the rack 209 moves to the other end of the quarter-circular gear. Thereafter, the rack 209 no longer engages with the gear 211, and the rack 209 continues to move, while the gear 211 does not rotate, and the ferry body 202 remains stationary. Therefore, through the above-mentioned design of the gear 211, it can be ensured that the ferry body 202 is only flipped within a range of 90° between horizontal and vertical, thereby avoiding the problem of excessive flipping of the ferry body 202.

[0061] In one embodiment of the present invention, the gear 211 is formed with a through hole, and the rotating shaft 203 is inserted into the through hole. Specifically, the through hole is arranged at the rotation center of the gear 211, and the rotating shaft 203 passes through the through hole and rotates synchronously with the gear 211.

[0062] In one embodiment of the present invention, the ferry turning device further comprises a connecting member 208 connected between the locking rod 205 and the rack 209. Furthermore, a guide groove is provided on the vehicle body connection frame 201, into which the connecting member 208 is inserted. The guide groove limits the position of the connecting member 208, thereby preventing the connecting member 208 from bending or deforming.

[0063] In one embodiment of the present invention, the ferry turning device further includes a stopper 210, which is fixed to the connector 208 and affixed to one side of the vehicle body connection frame 201, and is used to limit the movement of the connector 208. Specifically, the stopper 210 can be a nylon block, which is mounted on the connector 208 and affixed to the vehicle body connection frame 201, limiting the movement of the connector 208 and preventing the connector 208 from bending or deforming.

[0064] In one embodiment of the present invention, the ferry flipping device also includes: a mounting seat 207, the mounting seat 207 is fixed on the vehicle body connecting frame 201, and the gear 211 is rotatably assembled on the mounting seat 207; the mounting seat 207 is used to install the gear 211, that is, the gear 211 seat.

[0065] The present invention further provides a gangway assembly, which includes the ferry turning device in the above embodiment of the present invention.

[0066] The present invention provides a gangway assembly, which includes the ferry plate turning device in the above embodiment of the present invention, and therefore has the beneficial effects described above.

[0067] The gangway assembly includes a bellows connecting and disconnecting device, Figures 7 to 11 The present invention provides a bellows coupling and uncoupling device, which includes a bellows assembly 100 mounted on a first carriage and a car body connection frame 201 mounted on a second carriage. It should be understood that the bellows assembly 100 and car body connection frame 201 are mounted on two adjacent carriages, respectively, to enable coupling and uncoupling of the bellows assembly 100 and car body connection frame 201.

[0068] Specifically, the bellows assembly 100 includes a bellows body 110 and a telescopic mechanism 120 .

[0069] One end of the bellows body 110 is fixed to the end of the first car, while the other end can telescope toward or away from the second car. A first locking member is provided at the other end of the bellows body 110. The fixed end of the telescopic mechanism 120 is connected to one end of the bellows body 110, while the telescopic end of the telescopic mechanism 120 is connected to the other end of the bellows body 110. The bellows body 110 is capable of telescopic movement due to its structure. Its main body is composed of multiple rings of tarpaulin and supported by a metal frame. Each ring of tarpaulin can be compressed and stretched. The entire bellows body 110 has compression and stretching functions and serves as the fundamental component for connecting and disconnecting the gangway. The telescopic movement of the bellows body 110 is powered by the telescopic mechanism 120, which drives the synchronous telescopic movement of the bellows body 110 through the horizontal telescopic movement of the telescopic mechanism 120.

[0070] The vehicle body connection frame 201 is provided with a second locking member capable of cooperating with the first locking member; when the bellows body 110 is connected to the vehicle body connection frame 201, the second locking member is locked with the first locking member; when the bellows body 110 is uncoupled from the vehicle body connection frame 201, the second locking member is unlocked with the first locking member.

[0071] When the telescopic mechanism 120 drives the bellows body 110 to move toward the second compartment, after reaching the position, the bellows assembly 100 is connected to the vehicle body connection frame 201 and maintains its connection state (i.e., Figure 8 When the bellows assembly 100 needs to be unpacked, the first locking member and the second locking member are first unlocked, and then the bellows body 110 is driven by the telescopic mechanism 120 to move away from the second compartment. Finally, the bellows body 110 is retracted into the first compartment, and the unpacking of the bellows assembly 100 is completed (i.e., Figure 9 status shown).

[0072] It should be understood that the first and second locking members are mutually locking and unlocking limiters, ensuring stable coupling and quick uncoupling. The coupling and uncoupling processes can be accomplished electronically or pneumatically, without manual intervention. In the above embodiment, the first locking member is a locking hook 117, and the second locking member is a locking rod 205.

The present invention provides a bellows coupling and uncoupling device, which can drive the bellows body 110 to perform telescopic movement through the telescopic mechanism 120, thereby providing power for its coupling and uncoupling; the first locking member and the second locking member can switch between a locked state and an unlocked state, thereby ensuring stable coupling and uncoupling of the bellows and rapid uncoupling; the bellows coupling and uncoupling device of the present invention can replace manual coupling and uncoupling operations, providing convenience for realizing rapid coupling and uncoupling of the entire vehicle, reducing waste of manpower and material resources and working time, and greatly improving work efficiency.

[0074] In one embodiment of the present invention, Figure 10 As shown, the bellows coupling and uncoupling device further includes a guide rail 116 and a slider 115. The guide rail 116 is fixed to the body of the first car and arranged parallel to the direction of extension of the body. The slider 115 is fixed to the bellows body 110 and slidably mounted on the guide rail 116. In this embodiment, two guide rails 116 are arranged on the outside of the body of the first car, and a slider 115 is mounted on each of the two guide rails 116. The sliders 115 are fixedly connected to the sides of the bellows body 110. The sliders 115 slide within the guide rails 116 to define the direction of extension and retraction of the bellows body 110.

[0075] In one embodiment of the present invention, the bellows body 110 includes: a first bellows 111, a second bellows 112 and a bellows connecting frame 113; one end of the first bellows 111 is fixed to the first carriage, and the other end of the first bellows 111 is connected to one end of the second bellows 112 through the bellows connecting frame 113; the telescopic end of the telescopic mechanism 120 is connected to the other end of the second bellows 112. In this embodiment, the bellows body 110 includes the first bellows 111, the second bellows 112 and the bellows connecting frame 113, and the second bellows 112 and the first bellows 111 are the front and rear bellows respectively, and the two are connected by the bellows connecting frame 113. The bellows body 110 adopts the above-mentioned composite structure, which can, on the one hand, increase the telescopic distance of the bellows body 110, and on the other hand, fix the front bellows (that is, the bellows connecting frame 113) during the telescopic process of the bellows body 110. Figure 10 and Figure 11 The second bellows 112 in the illustrated structure also serves as the support point for the entire bellows, ensuring the structural stability of the bellows body 110. The telescopic mechanism 120 moves the front bellows (i.e., the second bellows 112), thereby achieving telescopic movement of the bellows body 110.

[0076] In one embodiment of the present invention, a slider 115 is fixed to the bellows connecting frame 113. Since the bellows connecting frame 113 in the above embodiment serves as the connecting structure for the front and rear bellows and as the support point for the entire bellows, fixing the slider 115 to the bellows connecting frame 113 can better define the direction of the bellows' telescopic movement, ensuring horizontal telescopic movement of the bellows. In this embodiment, the guide rails 116 and slider 115 both support the bellows connecting frame 113 and provide guidance for the bellows' movement through the bellows connecting frame 113.

[0077] In one embodiment of the present invention, the bellows body 110 further includes a bellows docking frame 114, which is fixed to the other end of the second bellows 112. The bellows docking frame 114 is configured to dock with the vehicle body connection frame 201, and a first locking member is provided on the bellows docking frame 114. In this embodiment, the bellows docking frame 114 is mounted on the front bellows (i.e., the second bellows 112) to mate with the vehicle body connection frame 201 on the second car body. When the bellows docking frame 114 and the vehicle body connection frame 201 are attached, the first locking member and the second locking member lock and engage, thereby achieving a connection between the bellows docking frame 114 and the vehicle body connection frame 201.

[0078] In one embodiment of the present invention, the telescopic mechanism 120 includes a drive motor 121 and a telescopic rod 122. The drive motor 121 is fixed to the first carriage; one end of the telescopic rod 122 is connected to the drive motor 121, and the other end of the telescopic rod 122 is connected to the bellows docking frame 114. In this embodiment, the drive motor 121 provides a power source, driving the telescopic rod 122 to telescope, thereby driving the bellows body 110 to telescope. Specifically, the telescopic end of the telescopic rod 122 is connected to the bellows docking frame 114. Its telescopic movement drives the bellows docking frame 114 to extend and retract, thereby driving the first bellows 111 and the second bellows 112 at its rear end to telescope synchronously.

[0079] In one embodiment of the present invention, the bellows assembly 100 further includes a step 130. One end of the step 130 is fixed to the bellows docking frame 114 and moves synchronously with the bellows docking frame 114. The other end of the step 130 is movably disposed within the first carriage. In this embodiment, the step 130 is connected to the bellows docking frame 114 and moves with the bellows docking frame 114. When the bellows docking frame 114 is fully extended, the step 130 also extends; when the bellows docking frame 114 is fully retracted, the step 130 also retracts.

[0080] The present invention further provides a rail vehicle, which may be a subway train, a city rail train, a high-speed rail train, or an unmanned train, and includes the gangway turning device or the gangway assembly of the above embodiment of the present invention.

[0081] The rail vehicle provided by the present invention has the same advantages as above because it includes the ferry turning device in the above embodiment of the present invention or the through-channel assembly in the above embodiment of the present invention.
