Abstract
Description
Technical Field
[0001] This invention relates to parallel trains, and more particularly to a synchronization device for parallel trains. Background Technology
[0002] To improve train transport efficiency, Chinese patent application CN118770295A discloses a method for train carriages, trains, and passengers to board and alight. This method requires locking two trains together during the exchange of movable carriages, with parallel operation at the same speed being a necessary condition for the exchange. The patent application discloses a locking structure where each carriage in a side-by-side train is mutually locked. However, this structure is only effective in one direction. If the train's direction of travel can be changed, a locking structure would need to be installed on each side of the train, making the process more complex. Summary of the Invention

[0004] The technical solution of the present invention is to construct a train synchronization device, including a first component and a second component respectively disposed at the rear of two trains.
[0005] The first component includes a telescopic rod and a telescopic rod drive mechanism. The telescopic rod drive mechanism is connected to and can drive the telescopic rod to move laterally. The end of the telescopic rod is provided with a plug, which points in the direction of train travel. The second component includes a socket. The socket includes a fixed block and a movable block that are rotatably engaged. The fixed block is provided with a notch corresponding to the movable block. When the movable block is inserted into the notch, the fixed block and the movable block can form a complete cylindrical insertion hole. The movable block is connected to the movable block drive mechanism. The notch faces the train parallel to the current train. The fixed block is provided with a pin and a pin drive mechanism. The fixed block is provided with a second limiting hole corresponding to the pin. The plug is provided with a first limiting hole. When the plug is inserted into the insertion hole of the socket, the first limiting hole can be aligned with the second limiting hole.
[0006] In one embodiment, the plug is thinner at the front end and thicker at the rear end, and 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 plug is thinner at the front end and thicker at the rear end, and the thickness of the movable block is not less than the thickness of the thickest part of the plug.
[0008] The rotating bushing connecting the movable block and the fixed block is located at the end of the insertion hole, and the rotating bushing smoothly transitions with the inner wall of the movable block.
[0009] In one embodiment, the opening of the socket is provided with a chamfer or rounded corner.
[0010] In one embodiment, one edge line of the upper and lower dividing surfaces of the fixed block and the movable block are respectively the upper and lower intersection lines of the insertion hole and the central vertical sectional surface. The upper dividing surface deflects upward from the inside to the outside starting from the upper intersection line, and the lower dividing surface deflects downward from the inside to the outside starting from the lower intersection line.
[0011] In one embodiment, the upper dividing surface of the fixed block and the movable block is a combination of a horizontal plane and a vertical plane, and one edge of the vertical plane is the upper intersection line of the insertion hole and the central vertical tangent; the lower dividing surface of the fixed block and the movable block is a combination of a horizontal plane and a vertical plane, and one edge of the vertical plane is the lower intersection line of the insertion hole and the central vertical tangent.

[0033] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
[0034] It should be noted that when an element is considered to be "set" on another element, it can be directly set on or connected to the other element, or an intermediate element may be present simultaneously. The terms "upper," "lower," "left," "right," "front," "back," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[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 art. The terminology used in this specification is for descriptive purposes only and is not intended to limit the invention. Example 1
[0036] As shown in Figure 1-10, a train synchronization device includes a first component 1 and a second component 2 respectively disposed at the rear of two trains, a and b. The first component 1 is disposed at the rear of train a and includes a telescopic rod 11 and a telescopic rod drive mechanism 12. The telescopic rod drive mechanism 12 is connected to and can drive the telescopic rod 11 to move laterally. The end of the telescopic rod 11 is provided with a plug 13, which points in the direction of train travel. The second component 2 is disposed 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 can be rotatably fitted to form a complete cylindrical insertion hole 23. The movable block 22 is connected to a movable block drive mechanism 28. The notch c on the fixed block 21 that accommodates the movable block 22 faces the train a parallel to train b. That is, the fixed block 21 is provided with a notch c corresponding to the movable block 22. When the movable block 22 is inserted into the notch c, the movable block 22 and the fixed block 21... A cylindrical insertion hole 23 is formed.
[0037] The fixing block 21 is provided with a pin 24 and a pin driving mechanism 25. The fixing block 21 is provided with a second limiting hole 26 corresponding to the pin 24. The plug 13 is provided with a first limiting hole 14. When the plug 13 is inserted into the socket hole 23, the first limiting hole 14 can be aligned with the second limiting hole 26.
[0038] As shown in Figures 6, 13, and 14, 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 location of the plug 13, and gradually increases outward (h>e in Figure 14).
[0039] The rotating bushing 27 of the movable block 22 connecting the fixed block 21 is located at the end of the insertion hole 23, and the rotating bushing 27 smoothly transitions with the inner wall of the movable block 22.
[0040] The opening of the socket 23 is provided with a chamfer g.
[0041] The upper dividing surface i and the lower dividing surface j of the fixed block 21 and the movable block 22 are respectively the upper intersection line m and the lower intersection line n of the insertion hole 23 and the central vertical tangent. The upper dividing surface i deflects upward from the inside to the outside starting from the upper intersection line m, and the lower dividing surface j deflects downward from the inside to the outside starting from the lower intersection line n. Example 2
[0042] As shown in Figures 11 and 12, unlike Embodiment 1, in this embodiment, the upper dividing surface i of the fixed block 21 and the movable block 22 is a combination of a horizontal and a vertical surface, and one side of the vertical surface is the upper intersection line k of the insertion hole 23 and the central vertical tangent; the lower dividing surface j of the fixed block 21 and the movable block 22 is a combination of a horizontal and a vertical surface, and one side of the vertical surface is the lower intersection line p of the insertion hole 23 and the central vertical tangent.
[0043] As shown in Figure 15, in this embodiment, the plug 13 is thin at the front end and thick at the rear end, 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, the plug can pass through any position of the corresponding notch in the fixed block 21.
[0044] The notch shape of the fixed block in the aforementioned embodiment can ensure that even if the plug moves relative to the train in the direction of travel, the fixed block and the movable block will not obstruct the movement of the plug during the process of the plug moving out through the notch, thus preventing jamming and safety risks. Example 3
[0045] As shown in Figure 1, a train set includes two trains, with a first component and a second component respectively installed at the rear of each train. Furthermore, the front of each train also has corresponding second and first components.
[0046] In the aforementioned embodiment, the notches of the movable block 22 and the corresponding fixed block 21 are generally wedge-shaped, narrower on the inside and wider on the outside, to facilitate the engagement of the movable block 22 and the fixed block 21. The plug 13 is thinner at the front end and thicker at the rear end, and the inner thickness of the movable block 22 is not less than the thickness at the corresponding part of the plug, and gradually thickens outward.
[0047] If the fitting accuracy between the movable block 22 and the fixed block 21 allows, 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, as shown in Figures 11 and 12.
[0048] The applications of this invention are shown in Figures 1, 7, and 10.
[0049] The express train and the slow train are traveling in the same direction. The first component 1 is located at the rear of the express train a, and the second component 2 is located at the rear of the slow train b. Before the express train a catches up with the slow train b, the telescopic rod drive mechanism on the express train pushes the telescopic rod into the slow train's path, aligning the plug 13 with the socket 23 on the slow train (as shown in Figures 7-1 and 8). The express train continues forward, inserting the plug 13 into the socket 23 (as shown in Figures 7-2 and 9). The pin 24 in the second component, under the action of the pin drive mechanism 25, inserts downwards into the aligned first limiting hole 14 and second limiting hole 26, completing the locking of the first and second components (as shown in Figures 7-2 and 7-3), thus locking the express and slow trains. After the express and slow trains are locked, operations such as exchanging movable cars can be performed.
[0050] After the movable cars have been exchanged, the process of separating the express and slow cars is shown in Figure 10. First, the pin 24 moves upward away from the first limit hole under the action of the pin drive mechanism. Then, the movable block drive mechanism 28 drives the movable block 22 to rotate, opening the notch of the fixed block 21 so that the plug 13 can be moved out of the notch, or releasing the supporting force of the movable block drive mechanism 28 so that the plug 13 can push open the movable block 22 when it is moved out. After that, the telescopic rod drive mechanism retracts the telescopic rod 11, driving the plug 13 away from the track of train b. After the plug 13 leaves the socket, the movable block drive 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 bearing 15 (as shown in Figure 13) or a roller 16 (as shown in Figure 16) or a bearing with the same function can be added to the top of the plug 13 to reduce the friction of the plug 13 during the sliding process on the movable block 22 and extend the service life of the equipment.
[0052] The plug cross-section in the embodiment is circular, but it is not limited to this in practical applications. The cross-section can also be elliptical, square, or other closed shapes.
[0053] In application, the express train and the local train travel on parallel, equidistant tracks. Just before catching up with the local train, the express train inserts its plug into the local train's track and into its socket, locking the two trains and preventing relative movement, thus allowing other operations to be performed. The same locking mechanism can be used to lock a pair of trains that have the structure of this invention installed at both the front and rear of the train after they change direction.
[0054] The embodiments described herein are merely preferred embodiments of the invention and are not intended to limit the concept and scope of the invention. Any modifications and improvements made by those skilled in the art to the technical solutions of the invention without departing from the design concept of the invention should fall within the protection scope of the invention. The technical content for which protection is sought in this invention has been fully described in the claims.
