Technical Field

[0001] The present invention relates to parallel trains, and particularly to a synchronization device for parallel trains. Background Art

[0002] In order to improve the transportation efficiency of trains, a Chinese patent application with the publication number CN118770295A discloses a train carriage, a train, and a method for passengers to get on and off. When exchanging movable carriages, this train needs to lock two trains, and achieving the same speed in parallel is a necessary condition for exchanging movable carriages. This patent application discloses a locking structure in which each train carriage arranged side by side is locked to each other. This structure is only effective in one direction. If the traveling direction of the train can be changed, a set of locking structures need to be provided on both sides of the train, which is relatively complex. Summary of the Invention

[0005] The first component includes a telescopic rod and a telescopic rod driving mechanism. The telescopic rod driving mechanism is connected to and can drive the telescopic rod to move horizontally. A plug is arranged at the end of the telescopic rod, and the plug points in the train advancing direction. The second component includes a socket. The socket includes a fixed block and a movable block that are rotatably matched. A notch corresponding to the movable block is arranged on the fixed block. When the movable block is embedded in the notch, a complete cylindrical jack can be formed between the fixed block and the movable block.

A bolt and a bolt driving mechanism are arranged on the fixed block. A second limit hole corresponding to the bolt is arranged on the fixed block. A first limit hole is arranged on the plug. When the plug is inserted into the jack of the socket, the first limit hole can be aligned with the second limit hole.

[0006] In one embodiment, the front end of the plug is thin and the rear end is thick. The inner thickness of the movable block is not less than the thickness of the corresponding part of the plug, and gradually thickens outward.

[0007] In one embodiment, the front end of the plug is thin and the rear end is thick. The thickness of the movable block is not less than the thickness of the thickest part of the plug.

[0008] The rotating shaft sleeve connecting the movable block and the fixed block is arranged at the end of the jack, and the rotating shaft sleeve and the inner wall of the movable block are in smooth transition.

[0009] In one embodiment, a chamfer or a rounded corner is provided at the orifice of the jack.

[0010] In one embodiment, one side line of the upper and lower split surfaces of the fixed block and the movable block are respectively the upper and lower intersection lines of the jack and the central vertical section plane. The upper split surface deflects upward from the inner side to the outer side starting from the upper split line, and the lower split surface deflects downward from the inner side to the outer side starting from the lower split line.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the present invention. The terms used in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Embodiment 1

[0036] As Figure 1-10 shown, a train synchronization device includes a first component 1 and a second component 2 respectively arranged at the rear ends of two trains a and b; The first component 1 is arranged at the rear of train a and includes a telescopic rod 11 and a telescopic rod driving mechanism 12. The telescopic rod driving mechanism 12 is connected to and can drive the telescopic rod 11 to move laterally. A plug 13 is arranged at the end of the telescopic rod 11, and the plug 13 points in the direction of train advancement; The second component 2 is arranged at the rear of train b and includes a socket. The socket includes a fixed block 21 and a movable block 22. The fixed block 21 and the movable block 22 are rotationally matched to form a complete cylindrical jack 23. The movable block 22 is connected to a movable block driving mechanism 28. The notch c on the fixed block 21 for accommodating the movable block 22 faces the train a parallel to the train b where the fixed block 21 is located; that is, a notch c corresponding to the movable block 22 is arranged on the fixed block 21. When the movable block 22 is inserted into the notch c, the movable block 22 and the fixed block 21 form a cylindrical jack 23.

[0037] A pin 24 and a pin driving mechanism 25 are arranged on the fixed block 21. A second limit hole 26 corresponding to the pin 24 is arranged on the fixed block 21. A first limit hole 14 is arranged on the plug 13. When the plug 13 is inserted into the jack 23 of the socket, the first limit hole 14 can be aligned with the second limit hole 26.

[0038] As Figure 6 、 13 、14 shown, in this embodiment, the front end of the plug 13 is thin and the rear end is thick. The inner thickness e of the movable block 22 is not less than the thickness f at the corresponding position of the plug 13 and gradually thickens outward ( Figure 14 where h > e in

[0039] The rotating shaft sleeve 27 connecting the movable block 22 to the fixed block 21 is arranged at the end of the jack 23, and the rotating shaft sleeve 27 has a smooth transition with the inner wall of the movable block 22.

[0040] A chamfer g is arranged at the orifice of the jack 23.

[0041] One edge line of the upper split surface i and the lower split surface j of the fixed block 21 and the movable block 22 is respectively the upper intersection line m and the lower intersection line n of the jack 23 and the central vertical section plane. The upper split surface i deflects upward from the upper intersection line m from the inside to the outside, and the lower split surface j deflects downward from the lower intersection line n from the inside to the outside. Embodiment 2

[0042] As Figure 11 、 12 shown, different from Embodiment 1, the upper split surface i of the fixed block 21 and the movable block 22 described in this embodiment is spliced by a horizontal plane and a vertical plane, and one edge of the vertical plane is the upper intersection line k of the jack 23 and the central vertical section plane; the lower split surface j of the fixed block 21 and the movable block 22 is spliced by a horizontal plane and a vertical plane, and one edge of the vertical plane is the lower intersection line p of the jack 23 and the central vertical section plane.

[0043] As Figure 15 shown, in this embodiment, the front end of the plug 13 is thin and the rear end is thick, the upper and lower surfaces of the movable block 22 are parallel, and the thickness q is not less than the thickness f at the corresponding position of the plug 13, that is, in the corresponding notch of the fixed block 21, the plug can pass through any position in the notch.

[0044] The notch shape of the fixed block in the foregoing embodiment can ensure that during the process of the plug moving out through the notch, even if the plug has a relative movement in the train running direction, the fixed block and the movable block will not block the movement of the plug, preventing jamming and safety risks. Embodiment 3

[0045] As Figure 1 shown, a train set includes two trains, and a first component and a second component are respectively arranged at the rear ends of the two trains. Further, corresponding second components and first components are also arranged at the front ends of the two trains.

[0046] In the foregoing embodiment, the notches of the movable block 22 and the corresponding fixed block 21 are integrally wedge-shaped with a narrow inner part and a wide outer part to facilitate the cooperation between the movable block 22 and the fixed block 21. The front end of the plug 13 is thin and the rear end is thick, and the inner thickness of the movable block 22 is not less than the thickness at the corresponding position of the plug and gradually thickens outward.

[0047] If the cooperation accuracy between the movable block 22 and the fixed block 21 permits, the notches of the movable block 22 and the corresponding fixed block 21 can also be set as an overall structure with equal width inside and outside and parallel up and down, as Figure 11 、 Figure 12 shown.

[0048] The application of the present invention is as Figure 1 、 7 、10 shown.

[0049] In the forward direction of the two trains, namely the fast train and the slow train, the first component 1 is arranged at the rear of the fast train a, and the second component 2 is arranged at the rear of the slow train b. Before the fast train a catches up with the slow train b, the telescopic rod driving mechanism on the fast train pushes out the telescopic rod into the route of the slow train, and aligns the plug 13 with the socket 23 on the slow train (as shown in Figure 7-1 and Figure 8 ). The fast train continues to move forward and inserts the plug 13 into the socket 23 (as shown in Figure 7-2 and Figure 9 ). The bolt 24 in the second component is inserted downward into the aligned first limiting hole 14 and the second limiting hole 26 under the action of the bolt driving mechanism 25, completing the locking of the first component and the second component (as shown in Figure 7-2 、7-3), that is, completing the locking of the fast train and the slow train. After the fast train and the slow train are locked, operations such as exchanging the movable carriages can be carried out.

[0050] After the exchange of the movable carriages is completed, the process of the separation of the fast train and the slow train is as shown in Figure 10 . First, the bolt 24 leaves the first limiting hole upward under the action of the bolt driving mechanism. Then the movable block driving mechanism 28 drives the movable block 22 to rotate, opening the notch of the fixed block 21, so that the plug 13 can move out from the notch, or the supporting force of the movable block driving mechanism 28 is released, so that the plug 13 can push open the movable block 22 when moving out. Then the telescopic rod driving mechanism retracts the telescopic rod 11, driving the plug 13 to leave the line of train b. After the plug 13 leaves the socket, the movable block driving mechanism 28 moves the movable block 22 to the notch of the fixed block 21, and train a and train b are unlocked.

[0051] As shown in Figure 13 , in order to reduce the friction between the plug 13 and the movable block 22 during the process of the plug 13 moving out of the socket, a ball 15 (as shown in Figure 13 ) or a roller 16 (as shown in Figure 16 ) with the same function or a bearing can also be added to the top of the plug 13 to reduce the friction during the sliding process of the plug 13 on the movable block 22 and extend the service life of the equipment.

[0052] In the embodiment, the cross-section of the plug is circular. In practical applications, it is not limited to this. The cross-section can also be oval, square or other closed figures.

[0053] When the present invention is applied, the fast train and the slow train move forward on parallel and equidistant tracks. When the fast train is about to catch up with the slow train, the fast train extends the plug into the track line of the slow train and inserts it into the socket of the slow train, locking the two trains and making them have no relative movement, and then allowing the trains to perform other operations. For a pair of trains with the structure of the present invention arranged at both the head and the tail, they can be locked with the same structure after changing directions.

[0054] The embodiments described in the present invention are only descriptions of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by those skilled in the art to the technical solutions of the present invention shall fall within the protection scope of the present invention. The technical content claimed by the present invention has been fully recorded in the claims.
