[0042] The long rail transport vehicle group is a special vehicle group composed of a variety of special carriages with different functions and structures for transporting welded long rails. An operation vehicle for operations such as rail receiving, rail unloading, and rail shifting of long rails is provided on the long rail transport vehicle. In the related art, a track for the operation vehicle to run is provided on each carriage of the long rail transport vehicle group. Since the tracks between adjacent two carriages are disconnected, an operation vehicle needs to be provided on each carriage, and the number of operation vehicles of the long rail transport vehicle group is relatively large.

[0043] In view of this, an embodiment of the present invention provides a long rail transport vehicle group. Between a first transport vehicle and a second transport vehicle arranged in sequence, a connecting device for connecting a first track and a second track is provided. The connecting device serves as an intermediate track between the first track and the second track and is used for the operation vehicle to move between the first track and the second track, so that the operation vehicle can move and operate between the first transport vehicle and the second transport vehicle, thereby reducing the number of operation vehicles of the long rail transport vehicle group.

[0044] The following introduces several optional implementation manners of the present invention in conjunction with the accompanying drawings. Those skilled in the art should understand that the following implementation manners are only illustrative and not an exhaustive list. Based on these implementation manners, those skilled in the art can replace, splice, or combine some features or some examples, and these should still be regarded as the disclosed content of the present invention.

[0045] Such as Figure 1As shown in the figure, the long rail transport vehicle group includes a first transport vehicle 10 and a second transport vehicle 20 arranged in sequence. A first track 11 and a first support column 12 for supporting the first track 11 are provided on the first transport vehicle 10. A second track 21 and a second support column 22 for supporting the second track 21 are provided on the second transport vehicle 20. A connecting device 30 is provided between the first track 11 and the second track 21 to connect the first track 11 and the second track 21, enabling the working vehicle to move between the first track 11 and the second track 21. It should be noted that the long rail transport vehicle group may include multiple groups of the first transport vehicle 10 and the second transport vehicle 20 arranged in sequence.

[0046] Referring to Figures 1 to 14 , the connecting device 30 includes a first connecting plate 31, a second connecting plate 32, a third connecting plate 33, and a fourth connecting plate 34 that are perpendicular to the horizontal plane, so that the first connecting plate 31, the second connecting plate 32, the third connecting plate 33, and the fourth connecting plate 34 form an intermediate track connecting the first track 11 and the second track 21, and the intermediate track is used for the working vehicle to move between the first track 11 and the second track 21.

[0047] The first connecting plate 31 is hinged to the first track 11 through a first hinge shaft perpendicular to the horizontal plane, so that when the long rail transport vehicle group turns, the first connecting plate 31 can rotate relative to the first track 11 with the first hinge shaft as the central axis, which is beneficial to the transmission of power between the first connecting plate 31 and the first track 11.

[0048] The first connecting plate 31 has a sliding channel extending along the extension direction of the first track 11, and the top end of the sliding channel has an opening. Exemplarily, referring to Figure 9 , the first connecting plate 31 is an installation cylinder 311 arranged parallel to the horizontal plane. The installation cylinder 311 is specifically a hexahedron structure surrounded by four rectangular flat plates. The installation cylinder 311 extends along the extension direction of the first track 11 to form a sliding channel, and the sliding channel is a hexahedron structure. Further, an opening is provided on the top plate of the installation cylinder 311, and the opening extends along the extension direction of the first track 11. A first guiding column 312 is also provided on the top plate of the installation cylinder 311, and the first guiding column 312 is parallel to the extension direction of the opening.

[0049] Correspondingly, the second connecting plate 32 includes a telescopic column 321 and a second guiding column 322 disposed at the top of the telescopic column 321. The telescopic column 321 is slidably disposed in the sliding channel. The second guiding column 322 extends out of the opening and abuts against the first guiding column 312, so that the first guiding column 312 and the second guiding column 322 can form part of the intermediate track. Specifically, the first guiding column 312 and the second guiding column 322 have a first width perpendicular to their extending direction and parallel to the top surface. The top of the first track 11 has a second width along its extending direction and parallel to the top surface. The first width is equal to the second width, so that the working vehicle can run smoothly between the first track 11 and the above-mentioned part of the intermediate track.

[0050] It should be noted that one end of the telescopic column 321 facing the first connecting plate 31 is provided with an inclined surface, which is beneficial to the quick insertion of the telescopic column 321 into the telescopic channel of the first connecting plate 31.

[0051] The second connecting plate 32 is hinged to the third connecting plate 33 by a second hinge shaft 371 perpendicular to the horizontal plane, so that when the long rail transport vehicle group turns, the second connecting plate 32 can rotate relative to the third connecting plate 33 with the second hinge shaft 371 as the axis, which is beneficial to the transmission of power between the second connecting plate 32 and the third connecting plate 33.

[0052] Such as Figures 2 to 6 and Figure 11 , one end of the fourth connecting plate 34 is connected to the second track 21. A bearing plate 35 parallel to the horizontal plane is provided at the bottom of the fourth connecting plate 34. A sliding groove is provided on the bearing plate 35. The third connecting plate 33 is slidably disposed in the sliding groove, so that the third connecting plate 33 can slide along the sliding groove, thereby driving the second connecting plate 32 to move towards the first connecting plate 31, so that the second connecting plate 32 is partially inserted into the sliding channel; or, the third connecting plate 33 drives the second connecting plate 32 to move away from the first connecting plate 31, so that the second connecting plate 32 is disengaged from the sliding channel.

[0053] Exemplarily, the third connecting plate 33 is generally a rectangular flat plate perpendicular to the horizontal plane. Correspondingly, the fourth connecting plate 34 is generally a rectangular flat plate. The fourth connecting plate 34 abuts against the third connecting plate 33, so that the third connecting plate 33 and the fourth connecting plate 34 can form part of the intermediate track. Specifically, the third connecting plate 33 and the fourth connecting plate 34 have a third width perpendicular to their extending direction and parallel to the top surface. The third width is equal to the second width, so that the working vehicle can run smoothly between the second track 21 and the above-mentioned part of the intermediate track.

[0054] The long rail transport vehicle group provided in this embodiment includes a first transport vehicle 10 and a second transport vehicle 20 arranged in sequence. A first track 11 is provided on the first transport vehicle 10, and a second track 21 is provided on the second transport vehicle 20. A connecting device 30 is arranged between the first track 11 and the second track 21. The connecting device 30 includes a first connecting plate 31, a second connecting plate 32, a third connecting plate 33, and a fourth connecting plate 34 that are perpendicular to the horizontal plane. The first connecting plate 31 is hinged to the first track 11 through a first hinge shaft perpendicular to the horizontal plane. The first connecting plate 31 has a sliding channel extending along the extending direction of the first track 11. The top of the sliding channel has an opening. A part of the second connecting plate 32 is slidably arranged in the sliding channel, and the top of the second connecting plate 32 extends out from the opening. The second connecting plate 32 is hinged to the third connecting plate 33 through a second hinge shaft 371 perpendicular to the horizontal plane. One end of the fourth connecting plate 34 is connected to the second track 21. A bearing plate 35 parallel to the horizontal plane is provided at the bottom of the fourth connecting plate 34. A sliding groove is provided on the bearing plate 35. The third connecting plate 33 is slidably arranged in the sliding groove. The first connecting plate 31, the second connecting plate 32, the third connecting plate 33, and the fourth connecting plate 34 form an intermediate track connecting the first track 11 and the second track 21. The intermediate track is used for the work vehicle to move between the first track 11 and the second track 21, so that the work vehicle can move and work between the first transport vehicle 10 and the second transport vehicle 20, thereby reducing the number of work vehicles in the long rail transport vehicle group.

[0055] Optionally, the connecting device 30 further includes a driving member. The driving member is connected to the third connecting plate and the fourth connecting plate 34. The driving member is used to drive the third connecting plate 33 to slide along the sliding groove, so that the third connecting plate 33 drives the second connecting plate 32 to move towards the first connecting plate 31, so that a part of the second connecting plate 32 is inserted into the sliding channel to form an intermediate track capable of connecting the first track 11 and the second track 21; or the third connecting plate 33 drives the second connecting plate 32 to move away from the first connecting plate 31, so that the second connecting plate 32 disengages from the sliding channel, and further disconnects the first track 11 and the second track 21.

[0056] As Figure 2 and Figure 12 shown, in this embodiment, the driving member includes a driving rod 60, a mating plate 331 provided on the third connecting plate 33, and a stopper 332 provided on the fourth connecting plate 34.

[0057] Exemplarily, the mating plate 331 can be a rectangular flat plate so that the mating plate 331 is perpendicular to the third connecting plate 33. A plurality of mating holes are provided on the mating plate 331 at intervals along the direction parallel to the extension of the first track 11. The structure of the mating holes should be designed accordingly according to the size of the driving rod 60. The stopper 332 can be a rectangular block. A rectangular groove is provided on one side of the rectangular block facing away from the second connecting plate 32. The size of the groove should be designed accordingly according to the size of the driving rod 60. In an implementable manner, the driving rod 60 can be a crowbar. One end of the crowbar extends into the mating hole, and a part of the crowbar is clamped in the groove. The crowbar drives the mating plate 331 to move along the extension direction of the first track 11 with the stopper 332 as a fulcrum, thereby driving the second connecting plate 32 to move synchronously and driving the third connecting plate 33 to move.

[0058] It should be noted that by setting the driving member, the rapid connection and disconnection of the connecting device 30 can be realized, which is beneficial to improving the operation efficiency and ensuring safe operation.

[0059] Referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 10 , optionally, a first adapter 38 is provided between the first connecting plate 31 and the first track 11. In this embodiment, a mounting seat 38 is further provided between the first connecting plate 31 and the first track 11. One end of the mounting seat 38 is connected to the first track 11, and the other end of the mounting seat 38 is connected to the first adapter 38.

[0060] Exemplarily, the mounting seat 38 can be a block structure. The first adapter 36 can include a rectangular column and flat plates provided on two opposite side walls of the rectangular column. The rectangular column is perpendicular to the horizontal plane so that the two flat plates and the rectangular column can generally form a U-shaped structure. Part of the mounting seat 38 can extend into the U-shaped opening of the first adapter 36. A first hinge hole is provided on the rectangular column. The central axis of the first hinge hole is perpendicular to the horizontal direction. The first hinge hole is used for passing through the first hinge shaft so that one end of the first adapter 36 and the first connecting member are hinged by the first hinge shaft. Third hinge holes are provided on the two flat plates. The central axis of the third hinge hole is parallel to the horizontal direction. The third hinge holes are used for passing through the third hinge shafts 362 so that the other end of the first adapter 36 and the mounting seat 38 are hinged by the third hinge shafts 362.

[0061] As Figure 10 shown, the third hinge shaft 362 can be a smooth round pin. A process hole is provided at the free end of the smooth round pin for passing through an opening pin to prevent the smooth round pin from loosening from the third hinge hole. Further, in order to prevent the opening pin from wearing against the first adapter 36, a washer can be provided between the opening pin and the first adapter 36.

[0062] By arranging a third hinge shaft 362 between the first connecting plate 31 and the first track 11, the first connecting plate 31 can rotate relative to the first track 11 with the third hinge shaft 362 as the axis, so that the horizontal distance between the outermost end of the first connecting plate 31 and the first track 11 is changed. In this way, when the long rail transport vehicle group speeds up or brakes, there is a certain amount of telescopic movement between the first connecting plate 31 and the first track 11, which is beneficial to the transmission of power between the first connecting plate 31 and the first track 11.

[0063] Refer to Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 , optionally, a second adapter 37 is arranged between the second connecting plate 32 and the third connecting plate 33. Exemplarily, the second adapter 37 may include a rectangular column and flat plates arranged on two opposite side walls of the rectangular column. The rectangular column is perpendicular to the horizontal plane, so that the two flat plates and the rectangular column can generally form a U-shaped structure, and a part of the third connecting plate 33 can extend into the U-shaped opening of the second adapter 37. A second hinge hole is arranged on the rectangular column, and the central axis of the second hinge hole is perpendicular to the horizontal direction. The second hinge hole is used for passing through a second hinge shaft 371, so that one end of the second adapter 37 and the second connecting plate 32 are hinged through the second hinge shaft 371. Fourth hinge holes are arranged on the two flat plates, and the central axes of the fourth hinge holes are parallel to the horizontal direction. The fourth hinge holes are used for passing through a fourth hinge shaft 372, so that the other end of the second adapter 37 and the third connecting plate 33 are hinged through the fourth hinge shaft 372.

[0064] As Figure 7 shown, the fourth hinge shaft 372 can be a smooth round pin, and a process hole is arranged at the free end of the smooth round pin for passing through a split pin to prevent the smooth round pin from loosening from the fourth hinge hole. Further, in order to prevent the split pin from wearing against the second adapter 37, a washer can be arranged between the split pin and the second adapter 37.

[0065] By arranging a fourth hinge shaft 372 between the second connecting plate 32 and the third connecting plate 33, the second connecting plate 32 can rotate relative to the third connecting plate 33 with the fourth hinge shaft 372 as the axis, so that the horizontal distance between the outermost end of the second connecting plate 32 and the third connecting plate 33 is changed. In this way, when the long rail transport vehicle group speeds up or brakes, there is a certain amount of telescopic movement between the second connecting plate 32 and the third connecting plate 33, which is beneficial to the transmission of power between the second connecting plate 32 and the third connecting plate 33.

[0066] Further, since a third hinge shaft 362 is provided between the first connecting plate 31 and the first track 11, and a fourth hinge shaft 372 is provided between the second connecting plate 32 and the third connecting plate 33, when the first connecting plate 31 and the second connecting plate 32 are connected, due to their own gravity, the first connecting plate 31 and the second connecting plate 32 will tilt at a certain angle towards the ground. As a result, during the operation of the long rail transport vehicle group, the friction between the first connecting plate 31 and the second connecting plate 32 increases, preventing the first connecting plate 31 and the second connecting plate 32 from detaching and improving the reliability of the connecting device 30.

[0067] Refer to Figure 1 and Figure 15 , optionally, the connecting device 30 further includes a jacking device provided on the first transport vehicle 10. The jacking device is used to jack against the bottom end of the first connecting plate 31. The jacking device can make the first connecting plate 31 parallel to the horizontal plane, which is beneficial to accurately inserting part of the second connecting plate 32 into the sliding channel of the first connecting plate 31.

[0068] In this embodiment, the first support column 12 has a first support plate 121 parallel to the horizontal plane. A driving tube is provided on the first support plate 121, and the inner wall of the driving tube has a driving internal thread; the jacking device includes a jacking rod 40. A driving external thread is provided on the jacking rod 40, and the driving external thread cooperates with the driving internal thread. A through hole is further provided at the bottom end of the jacking rod 40 so that a connecting rod can be inserted into the through hole to drive the jacking rod 40 to rotate. At the same time, due to the cooperation of the driving external thread and the driving internal thread, the jacking rod 40 moves in a direction perpendicular to the first connecting plate 31. When the connecting rod is rotated to move the jacking rod 40 towards the first connecting plate 31 until the top end of the jacking rod 40 jacks against the first connecting plate 31, due to the supporting force of the jacking rod 40 on the first connecting plate 31, the jacking rod 40 makes the first connecting plate 31 parallel to the horizontal plane, which is beneficial to accurately inserting part of the second connecting plate 32 into the sliding channel of the first connecting plate 31. Of course, when the connecting rod is rotated in the opposite direction to move the jacking rod 40 away from the first connecting plate 31, the jacking rod 40 will disengage from the first connecting plate 31, and the first connecting plate 31 will rotate towards the ground due to its own gravity.

[0069] It should be noted that a plurality of first support plates 121 can be provided on the first support column 12, and corresponding driving tubes are provided on each first support plate 121. As Figure 15 shown, two first support plates 121 can be provided.

[0070] Refer to Figure 1 and Figure 16, optionally, the connecting device 30 further includes a locking post 50. A first locking hole 351 is provided on the bearing plate 35, and a second locking hole 333 is provided on the third connecting plate 33. The locking post 50 is inserted into the first locking hole 351 and the second locking hole 333 to fix the bearing plate 35 and the third connecting plate 33, so that the second connecting plate 32 and the first connecting plate 31 remain connected, thereby further preventing the second connecting plate 32 from separating from the first connecting plate 31.

[0071] Further, a second support post 22 for supporting the second track 21 is provided on the second transport vehicle 20. The second support post 22 is provided with a stop device for preventing the locking post 50 from moving perpendicular to the horizontal direction, so that the locking post 50 remains inserted into the first locking hole 351 and the second locking hole 333, thereby fixing the bearing plate 35 and the third connecting plate 33.

[0072] Exemplarily, the stop device includes a hook 52. A rotating rod 51 is provided at the bottom end of the locking post 50. The rotating rod 51 is perpendicular to the locking post 50. Rotating the rotating rod 51 and hooking the hook 52 to the rotating rod 51 can prevent the locking post 50 from moving in a direction perpendicular to the third connecting plate 33, and further keep the locking post 50 inserted into the first locking hole 351 and the second locking hole 333. Of course, rotating the rotating rod 51 in the opposite direction can disengage the rotating rod 51 from the hook 52, so that the locking post 50 disengages from the first locking hole 351 and the second locking hole 333, and further enables the third connecting plate 33 to slide relative to the bearing plate 35.

[0073] It should be noted that in some other embodiments, a third locking hole may also be provided at the bottom of the second connecting plate 32, so that the locking post 50 is inserted into the first locking hole 351 and the third locking hole to fix the bearing plate 35 and the second connecting plate 32, so that the second connecting plate 32 and the first connecting plate 31 remain separated.

[0074] The working process of the connecting device 30 provided in this embodiment will be briefly described below.

[0076] Then, use the driving rod 60 to drive the mating plate 331 to move closer to the first connecting plate 31 with the stop block 332 as the fulcrum, thereby driving the second connecting plate 32 to drive the third connecting plate 33 to move closer to the first connecting plate 31 until a part of the second connecting plate 32 is inserted into the sliding channel of the first connecting plate 31, and at the same time the first guiding column 312 and the second guiding column 322 are in mutual contact. Then rotate the locking column 50 so that the locking column 50 passes through the first locking hole 351 and the second locking hole 333, and rotate the abutting rod 40 so that the top end of the abutting rod 40 is away from the bottom surface of the first connecting plate 31. At this time, the connecting device 30 is completed, and an intermediate track capable of passing the work vehicle is formed between the first track 11 and the second track 21.

[0077] In the case where it is necessary to disassemble the connecting device 30 to disconnect the first track 11 from the second track 21: Rotate the locking column 50 so that the locking column 50 disengages from the first locking hole 351 and the second locking hole 333, and rotate the abutting rod 40 so that the top end of the abutting rod 40 abuts against the bottom surface of the first connecting plate 31, and the abutting rod 40 makes the first connecting plate 31 parallel to the horizontal plane.

[0078] Then, use the driving rod 60 to drive the mating plate 331 to move away from the first connecting plate 31 with the stop block 332 as the fulcrum, thereby driving the second connecting plate 32 to drive the third connecting plate 33 to move away from the first connecting plate 31 until a part of the second connecting plate 32 disengages from the sliding channel of the first connecting plate 31, and at the same time the first guiding column 312 and the second guiding column 322 are disengaged from each other. Then rotate the abutting rod 40 so that the top end of the abutting rod 40 is away from the bottom surface of the first connecting plate 31. At this time, the connecting device 30 is completed for disassembly, and the first track 11 and the second track 21 are disconnected.
