[0002] The long rails used in railway track laying need to be transported to the designated line by a rail transport vehicle. During the transportation of the rails, several groups of roller beams are required to support the rails.

[0003] Generally, multiple layers of roller beams are installed on the underframe of the long rail transport vehicle. The two ends of the roller beams are respectively connected to the columns on both sides of the underframe. The rails are arranged side by side on the roller beams. Rails can be placed on each layer of roller beams, and the rails are supported by the roller beams.

[0004] However, during the transportation of the rails by the above-mentioned long rail transport vehicle, when passing through a curved section, such as during a turn, the rails will tend to deviate to one side due to inertia, resulting in uneven loading of the long rail transport vehicle. In this way, it is easy to cause potential safety hazards for the long rail transport vehicle and accidents are likely to occur. Summary of the Invention

It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0054] For the long steel rails used in railway track laying, the steel rails need to be transported to the designated line by a steel rail transport vehicle. During the transportation of the steel rails, several groups of roller beams are required to support the steel rails. Due to the width limitation of the steel rail transport vehicle, the roller beams can be arranged in multiple layers, and the steel rails are placed in layers on the steel rail transport vehicle, and the steel rails are placed layer by layer from the lower roller beam to the upper roller beam. When unloading the steel rails from the steel rail transport vehicle, the steel rails are unloaded layer by layer from the upper roller beam to the lower roller beam.

[0055] In order to facilitate the placement and fixation of the steel rails, multiple layers of roller beams are installed on the underframe of the long steel rail transport vehicle. The two ends of the roller beams are respectively connected to the columns on both sides of the underframe. The steel rails are arranged side by side on the roller beams, and the steel rails can be placed on each layer of roller beams, and the steel rails are supported by the roller beams. However, during the transportation of the steel rails by the long steel rail transport vehicle, if passing through a curved section, such as when turning, the steel rails will tend to deviate to one side due to inertia, which is likely to cause uneven loading of the long steel rail transport vehicle. In this way, it poses a driving hazard to the long steel rail transport vehicle and may even cause an accident in severe cases.

[0056] Based on this, the embodiments of the present application provide a long steel rail transport vehicle, which fixes the steel rails within a certain area through a spacer beam to prevent the steel rails from shifting due to inertia.

[0057] Figure 1 Schematic structural diagram of the long steel rail transport vehicle provided by the embodiment of the present application;Figure 2 Structural schematic diagram of the support structure in the long rail transport vehicle provided by the embodiment of the present application; Figure 3 Structural schematic diagram of the raceway beam assembly in the long rail transport vehicle provided by the embodiment of the present application; Figure 4 Top view of the raceway beam assembly in the long rail transport vehicle provided by the embodiment of the present application; Figure 5 Structural schematic diagram of the spacer beam in the long rail transport vehicle provided by the embodiment of the present application; Figure 6 is Figure 5 Cross-sectional view of the A-A section in Figure 7 Usage state diagram of the long rail transport vehicle provided by the embodiment of the present application.

[0058] Referring to Figures 1 to 7 As shown, the long rail transport vehicle provided by the embodiment of the present application includes a vehicle body 100 and at least two support structures provided on the vehicle body 100. The support structures are arranged at intervals along the length direction of the vehicle body 100. The support structure includes a support unit 200 and a raceway beam unit provided on the support unit 200.

[0059] At least one raceway beam unit includes at least two layers of raceway beam assemblies 300, and each raceway beam assembly 300 is arranged at intervals along the height direction of the support unit 200.

[0060] The raceway beam assembly 300 includes a roller beam 310 and a spacer beam 320 connected to the roller beam 310. A plurality of steel rails 400 are placed on the roller beam 310, and the steel rails 400 are arranged at intervals along the extension direction of the roller beam 310. One steel rail 400 or at least two adjacent steel rails 400 form a steel rail group. The spacer beam 320 has a plurality of spaced spacers 321. The spacers 321 can rotate relative to the roller beam 310 in a preset direction above the roller beam 310 to space adjacent steel rail groups, or rotate in the opposite direction of the preset direction relative to the roller beam 310 so that the spacers 321 are located below the roller beam 310.

[0061] In specific implementation, the number of support structures can be two or more. Thus, the steel rails 400 can be stably supported. In this embodiment and the accompanying drawings, the number of support structures is three for illustration. Among them, a spacer beam 320 can be provided in the raceway beam unit of one support structure, and the raceway beam units in the remaining support structures can be the raceway beam units in the prior art, or spacer beams 320 can be provided in the raceway beam units of two or more support structures, and the raceway beam units in the remaining support structures can be the raceway beam units in the prior art. In this embodiment, the raceway beam assembly 300 of the raceway beam unit of the middle support structure is described with a spacer beam 320.

[0062] In this embodiment, the roller beam 310 is used to carry the rail 400. Based on the long strip structure of the rail 400, during loading and unloading, it operates along the length direction of the vehicle body of the long rail transport vehicle. The extending direction of the roller beam 310 is along the width direction of the vehicle body of the long rail transport vehicle. A plurality of rails 400 are arranged at intervals along the width direction of the vehicle body on the roller beam 310 of the track beam assembly 300. During the operation of loading and unloading the rails, the roller beam 310 provides a loading and unloading passage for the rails 400.

[0063] Before the long rail transport vehicle travels, the spacer 321 can be rotated clockwise and turned up relative to the roller beam 310. The spacer 321 is located above the roller beam 310. At this time, the spacer 321 is perpendicular to the roller beam 310, or there is an included angle between the spacer 321 and the roller beam 310. Thus, the rails 400 located on the roller beam 310 are spaced by the spacer 321, and the adjacent spacer beams 320 fix the rails 400 therein within a certain area. In this way, when the long rail transport vehicle travels through a turning or curved section, the spacer beam 320 can prevent the rails 400 from shifting under the action of inertia force, and avoid partial load of the long rail transport vehicle. During the operation of loading or unloading the rails 400, the spacer 321 can be rotated counterclockwise and lowered relative to the roller beam 310, so that the spacer 321 is located below the roller beam 310, thus avoiding the spacer 321 from affecting the loading and unloading of the rails 400.

[0064] Figure 8 It is the right view of the support structure in the long rail transport vehicle provided by the embodiment of the present application. Refer to Figures 4 to 8 As shown, in some embodiments, the spacer beam 320 includes a rotating shaft 322 and a support 323 located on the rotating shaft 322. The spacer 321 is sleeved on the rotating shaft 322, and the support 323 is connected to the roller beam 310.

[0065] Among them, the support 323 is connected to the roller beam 310 by bolts. Correspondingly, a connection hole 324 is provided on the support 323, and a through hole is provided on the roller beam 310. The support 323 can also be connected to the roller beam 310 by riveting or welding, etc. This embodiment does not limit this here. Through holes can be provided on the support 323, and the rotating shaft 322 passes through the through holes to connect the support 323 to the rotating shaft 322. There is a gap between the inner side wall of the through hole and the outer side wall of the rotating shaft 322, so that the rotating shaft 322 can rotate smoothly.

[0066] The raceway beam assembly 300 further includes a driving member 330 for driving the rotating shaft 322 to rotate. Among them, the driving member 330 can be directly connected to the rotating shaft 322. The driving member 330 can be a motor, and the output shaft of the motor is connected to the rotating shaft 322 through a coupling, thereby driving the rotating shaft 322 to rotate. The driving member 330 can also be a rotary cylinder. In some embodiments, the driving member 330 can be connected to the rotating shaft 322 by means of chain drive, gear drive or chain drive to drive the rotating shaft 322 to rotate. This embodiment is not limited herein.

[0067] Among them, the rotating shaft 322 can include a first shaft body 3221 and a second shaft body 3222. The first shaft body 3221 and the second shaft body 3222 are coaxially connected through a sleeve 325 and a flat key 326. Among them, the first shaft body 3221 can be connected to the driving member 330.

[0068] Two adjacent steel rails 400 form a steel rail group. In this application, one steel rail 400 can form a steel rail group, that is, there is one steel rail between two spacers 321. Refer to Figure 7 As shown, two adjacent steel rails 400 form a steel rail group in pairs, that is, there are two steel rails 400 between two spacers 321. It is also possible that three adjacent steel rails 400 form a steel rail group. The number of steel rails 400 spaced between two spacers 321 can be two to three. If the number of steel rails 400 spaced between two spacers 321 is less than two, the number of steel rails 400 placed on the roller beam 310 is small. If the number of steel rails 400 spaced between two spacers 321 is greater than three, the function of the spacer 321 for spacing the steel rails 400 is weakened.

[0069] Please continue to refer to Figure 5 and Figure 6 As shown, in some embodiments, the number of supports 323 is multiple. The supports 323 are arranged in one-to-one correspondence with the spacers 321, and the support 323 abuts against the adjacent spacer 321. The distance between two adjacent supports 323 is the same as the distance between two adjacent spacers 321.

[0070] In specific implementation, the number of supports 323 and spacers 321 can be set according to the number of steel rail groups to be carried, as long as the supports 323 and spacers 321 are arranged in one-to-one correspondence. The spacer 321 can be in interference fit with the rotating shaft 322.

[0071] Please continue to refer to Figures 2 to 7As shown, in the present application, at least two layers of raceway beam assemblies 300 include a first raceway beam assembly 300a and at least one layer of second raceway beam assemblies 300b. Each second raceway beam assembly 300b is located above the first raceway beam assembly 300a. The driving member 330 is connected to the second raceway beam assembly 300b to drive the second raceway beam assembly 300b to rotate relative to the support unit 200, so that the second raceway beam assembly 300b is located above the first raceway beam assembly 300a or on the side of the first raceway beam assembly 300a.

[0072] Specifically, both ends of the first raceway beam assembly 300a can be fixed to the bottom of the support unit 200. The number of second raceway beam assemblies 300b can be three. The three second raceway beam assemblies 300b are, from the bottom to the top of the support unit 200, the lower second raceway beam assembly 300b, the middle second raceway beam assembly 300b, and the upper second raceway beam assembly 300b. Among them, the lower second raceway beam assembly 300b is located between the first raceway beam assembly 300a and the middle second raceway beam assembly 300b. The driving member 330 for driving the lower second raceway beam assembly 300b, the middle second raceway beam assembly 300b, and the upper second raceway beam assembly 300b can be the same driving member 330, or can respectively correspond to different driving members 330. The driving member 330 here can be the driving member 330 that drives the rotation of the driving shaft 322, that is, while one driving member 330 drives the driving shaft 322 to rotate, it also drives the second raceway beam assembly 300b to rotate relative to the support unit 200.

[0073] When installing the rail, first, drive each second raceway beam assembly 300b to rotate 90° through the driving member 330, thereby opening each second raceway beam assembly 300b, positioning each second raceway beam assembly 300b on the side of the first raceway beam assembly 300a, and placing the rail 400 on the first raceway beam assembly 300a. Secondly, drive the lower second raceway beam assembly 300b to rotate reversely 90° through the driving member 330, so that the lower second raceway beam assembly 300b is located above the first raceway beam assembly 300a, and place the rail 400 on the lower second raceway beam assembly 300b. Then, drive the middle second raceway beam assembly 300b to rotate reversely 90° through the driving member 330, so that the middle second raceway beam assembly 300b is located above the lower second raceway beam assembly 300b, and place the rail 400 on the middle second raceway beam assembly 300b. Finally, drive the upper second raceway beam assembly 300b to rotate reversely 90° through the driving member 330, so that the upper second raceway beam assembly 300b is located above the middle second raceway beam assembly 300b, and place the rail 400 on the upper second raceway beam assembly 300b. The order of unloading the rail 400 is opposite to that of loading the rail 400. The rail 400 is unloaded from the upper second raceway beam assembly 300b, the middle second raceway beam assembly 300b, the lower second raceway beam assembly 300b, and the first raceway beam assembly 300a in sequence, which will not be elaborated here one by one.

Refer to Figure 2 、 Figure 4 、 Figures 8 to 11 As shown in, the support unit 200 includes a first side column assembly 210 and a second side column assembly 220 which are oppositely arranged. One end of the roller beam 310 is rotatably connected to the first side column assembly 210, and the other end of the roller beam 310 can be placed on the second side column assembly 220.

[0075] Among them, the structures of the first side column assembly 210 and the second side column assembly 220 can be the same. The first side column assembly 210 may include a column body 212 and multiple layers of support platforms 213 located on the column body 212. The column body 212 is connected to the vehicle body 100 of the long rail transport vehicle. The support platforms 213 correspond to the first raceway beam assembly 300a and the second raceway beam assembly 300b one by one. One end of the roller beam 310 has an eccentric sleeve 3114, and the eccentric sleeve 3114 is rotatably connected to the support platform 213 on the first side column assembly 210, and the other end of the roller beam 310 can be placed on the support platform 213 of the second side column assembly 220.

Refer to Figure 2 、 Figures 10 to 14 As shown in

[0077] In a specific implementation, the locking assembly 350 includes a turntable 352 and a support shaft 354. One end of the support shaft 354 is hinged to the roller beam 310. The top of the first side column assembly 210 has a support groove 211. The support shaft 354 can rotate relative to the roller beam 310 to be lapped on the support groove 211.

[0078] The turntable 352 is sleeved on the support shaft 354 and is threadedly connected to the support shaft 354. One end of the support shaft 354 and the turntable 352 are respectively located on opposite sides of the first side column assembly 210. The turntable 352 can move relative to the roller beam 310 under the action of an external force and abut against the outer side surface of the first side column assembly 210.

[0079] Among them, the number of the locking assemblies 350 is three. The three locking assemblies 350 are arranged on the three support units 200 of each long rail transporter, and each locking assembly 350 is respectively connected to the upper second roller beam assembly 300b.

[0080] One end of the support shaft 354 of the locking assembly 350 is movably hinged to the other end of the roller beam 310 through a second split pin 355, a semi-finished round pin 356, and a locking support 3111. Part of the support shaft 354 can be inserted into the support groove 211 at the top of the first side column assembly 210. When the upper second roller beam assembly 300b needs to be rotated and opened, the support shaft 354 rotates relative to the locking support 3111 to above the roller beam 310, so that the locking assembly 350 is disengaged from the first side column assembly 210. When the upper second roller beam assembly 300b is closed, part of the support shaft 354 is inserted into the support groove 211, and the turntable 352 is rotated. The movement of the turntable 352 relative to the support shaft 354 enables the turntable 352 to provide a certain locking force to the first side column assembly 210, so as to fix the roller beam assembly 300 between the first side column assembly 210 and the second side column assembly 220. Thus, it is possible to prevent the roller beam assembly 300 from deforming when the rail 400 is in a fully loaded state.

[0081] To prevent the turntable 352 from detaching from the support shaft 354, a first split pin 351 is provided at the other end of the support shaft 354, and the turntable 352 is restricted on the support shaft 354 by the first split pin 351. A washer 353 is provided between the turntable 352 and the first side column assembly 210. The washer 353 is sleeved on the support shaft 354, and the washer 353 can prevent the outer side surface of the first side column assembly 210 from being damaged when the turntable 352 is over-locked. Among them, the material of the washer 353 can be a metal material or a non-metal material, which is not limited in this embodiment.

[0082] Please continue to refer to Figure 4 、 Figure 13 and Figure 14 As shown, the roller beam 310 includes a roller beam body 311 and a plurality of rollers 360. The rollers 360 are respectively rollingly connected to opposite sides of the roller beam body 311, and the axes of the rollers 360 are arranged along the extension direction of the roller beam body 311.

[0083] The rollers 360 located on the same side of the roller beam body 311 are arranged at intervals. The rollers 360 located on the same side of the roller beam body 311 are spaced opposite to the adjacent rollers 360 on the other side of the roller beam body 311. The rollers 360 are respectively used to carry different rails 400.

[0084] The rollers 360 located on the same side of the roller beam body 311 are inclined towards the middle of the roller beam body 311 to move closer to the middle of the roller beam body 311.

[0085] In a specific implementation, a plurality of first roller support members 3112 and second roller support members 3113 are respectively located on opposite sides of the roller beam body 311. The rollers 360 are respectively rollingly connected between two adjacent first roller support members 3112 or between two adjacent second roller support members 3113. The lower surface of the rail 400 is in rolling contact with the wheel surface of the roller 360. Thus, it is convenient for the long rail transport vehicle to load and unload the rail 400, and the operation efficiency of the long rail transport vehicle is improved.

[0086] The rollers 360 on the same side of the roller beam body 311 are inclined towards the middle of the roller beam body 311 and are installed in an inverted V shape when viewed from the rear side of the long rail transport vehicle body. During the operation of the long rail transport vehicle, the rail 400 can be guided to move closer to the vehicle center, preventing the rail 400 from deviating to one side due to inertial force and causing uneven load and potential traffic hazards.

[0087] Figure 15 For Figure 4 the sectional view of the B-B section in Figure 14 and Figure 15As shown in the figure, the long rail transport vehicle further includes a guide plate 340, which is connected to the middle part of the roller beam body 311, and the guide plate 340 and the spacer beam 320 are respectively located on opposite sides of the roller beam body 311.

[0088] The guide plate 340 is inclined from the rear side of the vehicle body 100 towards the front side of the vehicle body 100, and the upper end of the guide plate 340 is located between the top of the roller 360 and the axis of the roller 360.

[0089] Specifically, the guide plate 340 can be connected to the second roller support 3113 in the middle of the roller beam body 311 by bolts. Among them, the second roller support 3113 can have an inclined surface that is inclined towards the roller 360. In this way, when the guide plate 340 is connected to the second roller support 3113, the guide plate 340 also inclines towards the roller 360, that is, the guide plate 340 is inclined from the rear side of the vehicle body 100 towards the front side of the vehicle body 100. In this way, when loading and unloading the rail 400, the guide plate 340 inclined towards the roller 360 can guide the rail 400 to move onto the roller 360, or guide the rail 400 to leave the roller 360. The upper end of the guide plate 340 is located between the top of the roller 360 and the axis of the roller 360. Therefore, when loading and unloading the rail 400, the rail 400 is prevented from hitting the roller beam body 311, and at the same time, it is convenient to guide the rail 400 onto the roller 360.

[0090] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
