[0062] In the prior art, when the long rail transport vehicle set is hoisted, a special rail changing vehicle is needed to place the rail on the long rail transport vehicle set, or an electric hoist is arranged on the long rail transport vehicle set, and the electric hoist is used to hoist the rail. However, when the long rail transport vehicle set in the prior art encounters a railway line with many curves and small turning radius, the rail is hoisted by the electric hoist or the rail changing vehicle, and the steel wire rope of the electric hoist or the rail changing vehicle cannot control the stress of the rail itself, so that the rail cannot be placed on the long rail transport vehicle set in the curve, thereby increasing the uncertainty in the operation process and being not conducive to safe operation.

[0063] In order to overcome the defects in the prior art, the rail operation vehicle set provided by the present application is designed through the rail loading and unloading device on each rail transport vehicle unit, so that the rail clamping assembly always generates a clamping transverse force on the rail when clamping the rail, and then the rail can be consistent with the extended track of the rail operation vehicle set when the rail is lifted on the curved line, so that the rail can be placed in the placement groove of the rail track beam assembly, and the rail can be loaded and unloaded and transported on the railway line with many curves and small turning radius. Moreover, the multiple rail transport vehicle units can be sequentially connected or detached, so that the transportation and loading and unloading of rails of different lengths can be met, labor can be saved, and construction safety is high.

[0064] The content of the present application will be described in detail below with reference to the drawings, so that those skilled in the art can more clearly and specifically understand the content of the present application.

[0065] Figure 1 The structure schematic diagram of the first part of the rail operation vehicle set provided by the present application is shown. Figure 2 The structure schematic diagram of the second part of the rail operation vehicle set provided by the present application is shown. Figure 3 The structure schematic diagram of the rail track beam assembly in the rail operation vehicle set provided by the present application is shown. Figure 4 The structure schematic diagram of the rail loading and unloading device in the rail operation vehicle set provided by the present application is shown. Figure 5 The structure schematic diagram of the rail transport vehicle unit in the rail operation vehicle set provided by the present application is shown.

[0066] As shown in the drawings, Figures 1 to 5 The present application provides a rail operation vehicle set 100 for loading and unloading and transporting rails 200, which comprises at least two rail transport vehicle units 110 connected in sequence, the rail transport vehicle unit 110 comprises a vehicle body 111, a rail track beam assembly 112 and a rail loading and unloading device 113, and the rail track beam assembly 112 and the rail loading and unloading device 113 are arranged on the vehicle body 111.

[0067] It can be understood that the rail transport vehicle unit 110 can be multiple, and can be sequentially connected or detached.

[0068] The rail track beam assembly 112 comprises a plurality of placement grooves 1121 for accommodating the rails 200.

[0069] Among them, the placement groove 1121 can be multiple.

[0070] In some embodiments, the rail track beam assembly 112 can comprise multiple layers of horizontal rail track beams and multiple layers of vertical rail track beams, and the multiple layers of horizontal rail track beams and the multiple layers of vertical rail track beams form multiple placement grooves 1121 capable of accommodating the rails 200. Such design can simultaneously transport multiple rails 200, thereby improving the efficiency of transporting the rails 200.

[0071] The rail loading and unloading device 113 comprises a driving assembly and a rail clamping assembly, the rail clamping assembly comprises a horizontal rail clamping frame 1131, a vertical rail clamping frame 1132 and a rail lifting device 1133, the vertical rail clamping frame 1132 is movably connected to the end of the horizontal rail clamping frame 1131, the rail lifting device 1133 is movably arranged on the vertical rail clamping frame 1132, and the rail lifting device 1133 is configured to clamp the rail 200.

[0072] It should be noted that the horizontal rail clamping frame 1131 and the vertical rail clamping frame 1132 are arranged perpendicular to each other, wherein the horizontal rail clamping frame 1131 is parallel to the vehicle body 111, and the vertical rail clamping frame 1132 is perpendicular to the vehicle body 111.

[0073] The driving assembly is arranged on the rail clamping assembly and is configured to drive the vertical rail clamping frame 1132 to move along the length direction of the horizontal rail clamping frame 1131, so as to change the relative position of each rail lifting device 1133 along the width direction of the rail service vehicle group 100, thereby adjusting the rail 200 to match the extension trajectory of the rail service vehicle group 100.

[0074] It should be noted that when the rail 200 is transported to the curved track section, the rail 200 will generate a rebound internal stress. When the rail 200 is placed on the rail service vehicle group 100 or on the ground, due to the friction between the long rail service vehicle group 100 or the ground and the rail 200, the rebound internal stress of the rail 200 is overcome, so that the rail 200 does not displace.

[0075] Therefore, when the rail 200 is lifted, the friction between the rail clamping assembly and the rail 200 still exists at this time, which can further overcome the rebound internal stress of the rail 200, and when the rail 200 is clamped by the plurality of rail clamping assemblies, the rail 200 can be kept in the same shape as the rail service vehicle group 100.

[0076] That is, when the rail service vehicle group 100 is on the curved track, the extension trajectory of the rail service vehicle group 100 is in a curved shape, and the clamped rail 200 is also in a curved shape at this time, and further, the rail 200 can be placed on the rail service vehicle group 100 to complete the transportation.

[0077] Specifically, the design of the rail loading and unloading device 113 on each rail transport vehicle unit 110 ensures that the rail clamping assembly always generates a clamping transverse force on the rail 200 when clamping the rail 200, so that the rail 200 can be consistent with the extension trajectory of the rail operation vehicle group 100 when the rail 200 is lifted on a curved line, thereby enabling the rail 200 to be placed into the placement groove 1121 of the rail roadbed beam assembly 112, and achieving the loading and unloading and transportation of the rail 200 on a railway line with many curves and small turning radii. Moreover, since the plurality of rail transport vehicle units 110 can be sequentially connected or detached from each other, the transportation and loading and unloading of rails 200 of different lengths can be achieved, labor is saved, and construction safety is high.

[0078] In an alternative embodiment, as shown in Figures 1 to 5 The vertical rail clamping frame 1132 is provided with a first telescopic arm (not shown in the figure), which is configured to move vertically within the vertical rail clamping frame 1132, and the rail lifting device 1133 is movably arranged at the end of the first telescopic arm.

[0079] It can be understood that the rail lifting device 1133 can move with the first telescopic arm, and the rail lifting device 1133 falls until it contacts and presses down the rail 200, the first telescopic arm has a pressing force limit, and the pressing action stops when the pressing force reaches a set value, and the rail 200 is clamped.

[0080] Specifically, the rail lifting device 1133 is mainly used for automatic clamping of the rail 200.

[0081] For example, the rail lifting device 1133 is connected to the ball valve and the first telescopic arm, the pressing action of the first telescopic arm is controlled by aligning the position of the rail 200, and the rail lifting device 1133 automatically clamps the rail 200.

[0082] The horizontal rail clamping frame 1131 is provided with a second telescopic arm (not shown in the figure), one end of the second telescopic arm is arranged on the horizontal rail clamping frame 1131, and the other end of the second telescopic arm is arranged on the vertical rail clamping frame 1132, and the second telescopic arm is configured to move horizontally within the horizontal rail clamping frame 1131.

[0083] Specifically, the first end of the second telescopic arm is movably arranged on the horizontal rail clamping frame 1131, and the other end of the second telescopic arm is fixedly or detachably arranged on the vertical rail clamping frame 1132. With the horizontal movement of the second telescopic arm within the horizontal rail clamping frame 1131, the vertical rail clamping frame 1132 can move away from or approach the horizontal rail clamping frame 1131.

[0084] In some embodiments, the second telescopic arm can also be connected to the vertical clamping rail frame 1132 in other ways, as long as the connection mode can be fixedly connected to the second telescopic arm and the vertical clamping rail frame 1132, which can achieve the purpose of the embodiment, and the connection mode of the second telescopic arm and the vertical clamping rail frame 1132 is not limited here.

[0085] In an alternative embodiment, as shown in Figure 4 The rail clamping assembly further comprises a vertical column 1134, the vertical column 1134 is provided with a third telescopic arm (not shown in the figure), and the driving assembly drives the third telescopic arm to move along the length direction of the vertical column 1134. The vertical column 1134 is provided with a rotating piece 1135 between the horizontal clamping rail frame 1131, so that the horizontal clamping rail frame 1131 rotates relative to the vertical column 1134.

[0086] It can be understood that, as shown in Figures 1 to 4 The vertical column 1134 is fixedly or detachably arranged on the vehicle body 111, for example, bolted.

[0087] The vertical column 1134 is connected with the horizontal clamping rail frame 1131, and as the third telescopic arm moves in the length direction of the vertical column 1134, the horizontal clamping rail frame 1131 moves away from or approaches the vertical column 1134.

[0088] Specifically, the design of the rotating piece 1135 can satisfy the rotation of the horizontal clamping rail frame 1131 relative to the vertical column 1134, so that the horizontal clamping rail frame 1131 can stop at multiple positions.

[0089] In an alternative embodiment, the driving assembly comprises a plurality of driving pieces, and the plurality of driving pieces respectively drive the first telescopic arm, the second telescopic arm and the third telescopic arm to move.

[0090] In some embodiments, the power of the driving piece can adopt hydraulic power, which can better drive the first telescopic arm, the second telescopic arm and the third telescopic arm to move, thereby conveniently realizing the multiple functions of transporting, loading and unloading the steel rail 200, bringing convenience to the on-site operation work, and ensuring the personal safety of the operator.

[0091] In addition, when hoisting and unloading the steel rail 200 in a small curve section, the above driving assembly is sensitive in action; and in a curve section, the internal stress of the steel rail 200 and its specific drop point can be controlled.

[0092] In an alternative embodiment, as shown in Figures 1 to 4 A plurality of limiting portions (not shown in the figure) are arranged in the length direction of the second telescopic arm, so that the second telescopic arm stops when moving to the limiting portion, and the plurality of limiting portions are arranged at intervals, and the distance between the adjacent two limiting portions is consistent with the width of the placing groove 1121.

[0093] The width of the placement groove 1121 matches the width of the steel rail 200.

[0094] It can be understood that the limiting part corresponds to the placement groove 1121, and the second telescopic arm stops when moving to the limiting part. By controlling the first telescopic arm to fall and press down, the steel rail 200 is accurately placed in the placement groove 1121 of the rolling beam assembly 112, the rail placement is completed, the long steel rail 200 is positioned and collected or unloaded at a fixed point, and the stability and safety of the long steel rail 200 operation are improved.

[0095] In an optional embodiment, as shown in Figures 1 to 4 The rail transport vehicle unit 110 at least one end of the steel rail operation vehicle group 100 includes a safety wall 114, and the safety wall 114 is located on the vehicle body 111.

[0096] It can be understood that the safety wall 114 is arranged at the front end of the steel rail operation vehicle group 100, or the safety wall 114 is arranged at the tail end of the steel rail operation vehicle group 100, or the safety wall 114 is arranged at both the front end and the tail end of the steel rail operation vehicle group 100.

[0097] In some embodiments, the steel rail operation vehicle group 100 with the safety wall 114 at both the front end and the tail end is used for transporting and unloading long steel rails 200, for example, 100m and each specification length of steel rails 200 below or above 100m. Specifically, for the transportation of long steel rails 200 of different lengths, the number of rail transport vehicle units 110 can be increased or decreased.

[0098] In other embodiments, the steel rail operation vehicle group 100 with the safety wall 114 at the front end or the tail end is used for transporting and unloading short steel rails 200, for example, transporting and unloading steel rails 200 of 25m or between 25m and 100m, or short steel rails 200 below 25m. Specifically, for the transportation of short steel rails 200 of different lengths, the number of rail transport vehicle units 110 can be increased or decreased. The embodiments of the present application are not limited too much here.

[0099] It should be noted that Figure 6 The structure diagram of the first buffer vehicle unit in the steel rail operation vehicle group provided by the embodiments of the present application is shown in Figure 1 and Figure 6 The rail transport vehicle unit 110 with the safety wall 114 at the front end of the steel rail operation vehicle group 100 is the first buffer vehicle unit 120.

[0100] It should be noted that Figure 7 The structure diagram of the second buffer vehicle unit in the steel rail operation vehicle group provided by the embodiments of the present application is shown in Figure 2 and Figure 7As shown in the drawings, the rail transport vehicle unit 110 at the tail end of the rail operation vehicle group 100 is provided with a safety wall 114, and is the second buffer vehicle unit 130.

[0101] In an alternative embodiment, the rail transport vehicle units 110 at both ends of the rail operation vehicle group 100 are provided with safety walls 114.

[0102] It can be understood that the safety wall 114 can prevent the accumulation of the rails 200 in the extension direction of the rail operation vehicle group 100, thereby improving the safety of the operation.

[0103] It should be noted that the shape, size and material of the safety wall 114 are not limited in the embodiments of the present application.

[0104] In an alternative embodiment, as shown in the drawings, Figure 1 and Figure 6 the rail transport vehicle unit 110 at one end of the rail operation vehicle group 100 is further provided with a generator set 115, and the generator set 115 is located at one side of the safety wall 114. The rail transport vehicle unit 110 at one end of the rail operation vehicle group 100 is selectively connected with the generator set 115.

[0105] It can be understood that the rail transport vehicle unit 110 provided with the generator set 115 is the first buffer vehicle unit 120, and the generator set 115 can provide power for the whole vehicle.

[0106] In an alternative embodiment, Figure 8 a structure diagram of a locking member in the rail operation vehicle group provided by the embodiments of the present application is provided; Figure 9 a structure diagram of a locking vehicle unit in the rail operation vehicle group provided by the embodiments of the present application is provided.

[0107] As shown in the drawings, Figure 2 , Figure 8 and Figure 9 the rail transport vehicle unit 110 at one end of the rail operation vehicle group 100 is provided with a safety wall 114, and at least two rail transport vehicle units 110 include a first rail transport vehicle unit 110. The first rail transport vehicle unit 110 and the rail transport vehicle unit 110 with the safety wall 114 are respectively located at opposite ends of the rail operation vehicle group 100.

[0108] The vehicle body 111 of the first rail transport vehicle unit 110 is provided with a locking member 116, and the locking member 116 is locked at opposite sides in the width direction of the rail 200.

[0109] It should be noted that the vehicle body 111 of the first rail transport vehicle unit 110 provided with the locking member 116 is the locking vehicle unit 140, and the locking member 116 can be locked at opposite sides in the width direction of the rail 200, thereby locking the rail 200.

[0110] It can be understood that the rail operation vehicle group 100 formed by sequentially connecting the locking vehicle unit 140 and the second buffer vehicle unit 130 is used for transporting and loading / unloading the short rail 200.

[0111] In addition, Figure 10 The top view of the rail operation vehicle group provided by the embodiment of the present application is shown in Figure 10 It should be noted that the rail operation vehicle group 100 formed by sequentially connecting the first buffer vehicle unit 120, the plurality of rail transporting vehicle units 110, the locking vehicle unit 140 and the second buffer vehicle unit 130 is used for transporting and loading / unloading the long rail 200.

[0112] In an alternative embodiment, as shown in Figures 1 to 9 The rail transporting vehicle unit 110 is provided with a guard plate 117 and a crossing plate 118. The guard plate 117 is located at the outer periphery of the rail transporting vehicle unit 110, and the plurality of rail transporting vehicle units 110 are connected to each other through the crossing plate 118.

[0113] It can be understood that the crossing plate 118 is mainly used for the operator to pass between the vehicle groups.

[0114] In some embodiments, the crossing plate 118 is mainly composed of a walkway, a folding page, a latch and the like.

[0115] In addition, it can be understood that the guard plate 117 is mainly used to prevent the impact of the rail 200 on the vehicle body 111 during the loading process from the ground.

[0116] Specifically, in the process of collecting and unloading rails on the line, it should be noted that first, the locomotive pulls the vehicle group to the rail collecting operation site and stops running, wherein the rail can be collected and unloaded within the range of 0-700mm outside the vehicle body 111. Then, during the operation, the wireless remote control system selects the rail loading and unloading device 113 that can be controlled together, or the remote control system selects any one rail loading and unloading device 113 to be controlled individually for adjustment.

[0117] When the wireless remote control system controls the rail clamping assembly in the rail loading and unloading device 113 to align with the position of the rail 200, the first telescopic arm in the vertical rail clamping frame 1132 is controlled to fall, so that the rail clamp 1133 contacts and presses down the rail 200. The first telescopic arm has a pressing force limit, and when the pressing force reaches the set value, the pressing action stops, and the rail 200 is clamped.

[0118] When the rail clamp 1133 clamps the rail 200, the driving member continues to drive the first telescopic arm and the second telescopic arm to move respectively until the rail 200 is placed in the placing groove 1121, and the locking vehicle unit 140 locks the rail 200, and the rail collecting is completed. The process of unloading the rail is opposite to that of collecting the rail, which will not be described in detail here.

[0119] The rail operation vehicle group provided by the embodiment of the present application is used for loading and unloading and transporting rails, and comprises at least two rail transporting vehicle units which are sequentially connected. The rail transporting vehicle unit comprises a vehicle body, a rail track beam assembly and a rail loading and unloading device, and the rail track beam assembly and the rail loading and unloading device are arranged on the vehicle body. The rail track beam assembly comprises a plurality of placing grooves for accommodating rails. The rail loading and unloading device comprises a driving assembly and a rail clamping assembly. The rail clamping assembly comprises a horizontal rail clamping frame, a vertical rail clamping frame and a rail lifting device. The vertical rail clamping frame is movably connected to the end of the horizontal rail clamping frame, and the rail lifting device is movably arranged on the vertical rail clamping frame and is configured to clamp the rail. The driving assembly is arranged on the rail clamping assembly and is configured to drive the vertical rail clamping frame to move along the length direction of the horizontal rail clamping frame, so as to change the relative position of each rail lifting device in the width direction of the rail operation vehicle group, thereby adjusting the rail to match the extension track of the rail operation vehicle group.

[0120] Through the design of the rail loading and unloading device on each rail transporting vehicle unit, the rail clamping assembly can always generate a clamping transverse force on the rail when clamping the rail, so that the rail can be consistent with the extension track of the rail operation vehicle group when the rail is lifted on a curved line, thereby the rail can be placed in the placing groove of the rail track beam assembly, and the rail can be loaded, unloaded and transported on a railway line with many curves and small turning radius. Moreover, the plurality of rail transporting vehicle units can be sequentially connected or detached, so that the transportation and loading and unloading of rails with different lengths can be met, labor is saved, and construction safety is high.
