[0068] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0069] In the description of the present application, it should be noted that unless specifically defined and limited, the terms “mounting”, “connection”, “connecting” should be understood in a broad sense, for example, it can be fixedly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements or the interaction relationship between two elements. For a person of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0070] In the description of the present application, it should be understood that the terms “upper”, “lower”, “front”, “back”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer” and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0071] The terms “first”, “second”, “third” (if any) in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0072] In addition, the terms “include” and “have” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or maintenance tool including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or maintenance tools.

[0073] The long rail transport vehicle is used for conveying long rails, and a plurality of rail supports are arranged at intervals along the extension direction of the vehicle body on the long rail transport vehicle, and the rail supports are used for supporting the long rails.

[0074] The rail support comprises a first column, a second column and a plurality of support beams located between the first column and the second column, the plurality of support beams are uniformly arranged at intervals in the vertical direction, and the long rails are placed on the support beams. The first column is provided with a rotating assembly, the first end of the support beam is welded with the rotating assembly, so that the support beam rotates relative to the first column along the horizontal direction through the rotating assembly, and the second column has a plurality of supports, the supports are arranged one by one corresponding to the support beams, and the second end of the support beam is overlapped on the support.

[0075] When loading or unloading the long rails on one of the support beams (hereinafter referred to as the first support beam), the second end of the support beam located above the first support beam (hereinafter referred to as the second support beam) needs to be removed from the support seat, so that the second support beam rotates relative to the first column at a certain angle to leave space for the loading or unloading work of the rails on the first support beam, and after the loading or unloading is completed, the second end of the second support beam needs to be moved again to above the corresponding support. In the following, the loading or unloading of the long rails on the support beam is simply referred to as the rail loading and unloading work.

[0076] The support beam deforms due to the bearing of the long rails, which makes it difficult for the second end of the support beam to overlap on the support of the second column. The height of the second end of the support beam can be changed by adjusting the included angle between the support beam and the first column, so that the height of the second end of the support beam is consistent with the height of the support, thereby overlapping the second end of the support beam on the support of the second column.

[0077] The first column can be arranged to include a support frame and a plurality of rotating assemblies, the support frame includes a plurality of support parts arranged in the vertical direction, the rotating assemblies are arranged on the support parts, the rotating assemblies are arranged one by one corresponding to the support beams, the rotating assemblies include a rotating shaft and a rotating sleeve, the rotating shaft is installed on the support part, the rotating sleeve is sleeved on the rotating shaft and the rotating sleeve is welded with the first end of the support beam, and the rotation of the rotating shaft relative to the rotating sleeve makes the support beam rotate relative to the first column. Since the first end of the support beam is welded with the rotating sleeve, the included angle between the support beam and the first column cannot be changed. In addition, the adjacent support parts are connected by welding, which makes the support frame formed by the support parts easy to deform, thereby making the height difference between the second end of the support beam and the height of the support greater.

[0078] The first stand can also be provided as a structure comprising a support frame and an integral rotating shaft, the integral rotating shaft penetrating through the height direction of the support frame, a plurality of rotating sleeves are sequentially sleeved on the rotating shaft in the vertical direction, in order to ensure the installation accuracy, rotating bearings are arranged between the rotating sleeves and the rotating shaft, and the first end of the support beam is welded with the rotating sleeve. Due to the arrangement of the bearing, there is no assembly gap between the rotating shaft and the rotating sleeve, when the height of the second end of the support beam needs to be adjusted, the angle of the integral rotating shaft relative to the vertical direction is adjusted, so that the integral rotating shaft is inclined, the included angle between the support beam and the first stand is changed, the height of the second end of the support beam is changed, and the height of the second end of each support beam cannot be adjusted independently.

[0079] The height of the second end of the support beam cannot be completely matched with the height of the support, when the height of the second end of the support beam is higher than the height of the support, there is a gap between the second end of the support beam and the support, the weight of the support beam and the long rail thereon is entirely borne by the first stand, the first stand is severely deformed, and the rail support cannot be used. When the height of the second end of the support beam is lower than the height of the support, the support beam cannot be lapped on the support, and the rail support cannot be used.

[0080] Based on this, the application provides a rail support and a long rail transport vehicle, the second end of the support beam assembly in the rail support can be lapped on the second stand unit.

[0081] Figure 1 A structural schematic diagram of the rail support provided by the embodiment of the application is provided; Figure 2 Figure 1 An enlarged view of A in FIG. Figure 3 Figure 2 An exploded structural schematic diagram of FIG. Figure 4 Figure 2 A partial sectional view of FIG.

[0082] Referring to FIG. Figures 1 to 4 The rail support provided by the application comprises a first stand unit 100, a second stand unit 200, a support beam unit 300 and an adjusting unit 400, the support beam unit 300 comprises at least two layers of support beam assemblies 310, and each support beam assembly 310 is sequentially and spacedly arranged between the first stand unit 100 and the second stand unit 200 in the vertical direction.

[0083] The first stand unit 100 comprises a first support frame 110 and at least two rotating assemblies 120, the rotating assemblies 120 are in one-to-one correspondence with the first ends of the support beam assemblies 310 and are rotationally connected, so that the support beam assemblies 310 rotate up and down, the rotating assemblies 120 are used for rotating the support beam assemblies 310 to the side of the first stand unit 100, and the second ends of the support beam assemblies 310 are lapped with the second stand unit 200.

[0084] ​​​The adjusting unit 400 comprises a fixed part 410 and a moving part 420, the fixed part 410 is located on the first column unit 100, the moving part 420 is in contact with the first end of the support beam assembly 310, the moving part 420 is detachably connected with the fixed part 410, and the moving part 420 is movable relative to the fixed part 410, so that the first end of the support beam assembly 310 and the fixed part 410 have a variable spacing.

[0085] The rail support provided by the present application is used for a long rail transport vehicle, and the long rails are placed on the rail support. The first column unit 100 and the second column unit 200 are located at two ends of the support beam unit 300 to support the support beam unit 300. The support beam unit 300 comprises at least two layers of support beam assemblies 310, so that the rail support forms a multi-layer structure, and the long rails can be placed on each layer of support beam assemblies 310. Please continue to refer to Figure 1 As shown, the extension direction of each support beam assembly 310 is referred to as a first direction X, the extension direction of the first column unit 100 or the second column unit 200 is referred to as a second direction Y, and the direction perpendicular to the first direction X and the second direction Y is referred to as a third direction Z.

[0086] The first end of each support beam assembly 310 is rotatably connected with the first column unit 100, and the second column unit 200 has a support part, and the second end of each support beam assembly 310 is overlapped on the support part of the second column unit 200.

[0087] Please continue to refer to Figure 1 and Figure 2 As shown, the first column unit 100 comprises a first support frame 110 and a rotating assembly 120, the first support frame 110 is used for mounting and supporting the rotating assembly 120, and the rotating assembly 120 is spaced apart on the first support frame 110 along the second direction Y. The first support frame 110 can be an integral casting, so that the strength of the first support frame 110 is higher, the anti-deformation ability is stronger, and the size precision of the integral casting is higher, so that the mounting precision of the rotating assembly 120 is higher.

[0088] Specifically, please continue to refer to Figure 1 As shown, the support beam assemblies 310 from top to bottom along the first column unit 100 (or the second column unit 200) can be sequentially referred to as a first support beam assembly 310a, a second support beam assembly 310b, a third support beam assembly 310c, and a fourth support beam assembly 310d, and so on.

[0089] The following will be described with an example that the support beam unit 300 includes two support beam assemblies 310. When the rail loading and unloading operation is performed on the second support beam assembly 310b, the first support beam assembly 310a needs to be rotated to the side of the first column unit 100 to leave space for the rail loading and unloading operation on the second support beam assembly 310b. After the rail loading and unloading operation on the second support beam assembly 310b is completed, the first support beam assembly 310a is rotated to be overlapped with the support part on the second column unit 200.

[0090] Specifically, each support beam assembly 310 corresponds to a rotating assembly 120, and the first end of the support beam assembly 310 is connected with the rotating assembly 120. The rotating assembly 120 can rotate relative to the first support frame 110 about the first axis L1 (the first axis L1 extends along the second direction Y), so that the support beam assembly 310 connected with the rotating assembly 120 can rotate relative to the first column unit 100 about the first axis L1, so as to rotate the support beam assembly 310 to the side of the first column unit 100 or to be overlapped with the support part on the second column unit 200.

[0091] The support beam assembly 310 is used to bear the long rail. Since the long rail has a large weight, the support beam assembly 310 may be deformed after long time use, so that the second end of the support beam assembly 310 cannot be overlapped with the support part on the second column unit 200.

[0092] In the rail support provided by the present application, the support beam assembly 310 is also hinged with the rotating assembly 120, so that the support beam assembly 310 can rotate relative to the rotating assembly 120 about the second axis L2 (the second axis L2 extends along the third direction Z), that is, the support beam assembly 310 can swing up and down in the plane formed by the first column unit 100 and the support beam assembly 310, so that the support beam assembly 310 and the first column unit 100 have a variable included angle, so that the height of the second end of the support beam assembly 310 can be changed.

[0093] The adjusting unit 400 is provided in one-to-one correspondence with the support beam assembly 310, and is located between the first end of the support beam assembly 310 and the rotating assembly 120. The adjusting unit 400 can change the distance between the first end of the support beam assembly 310 corresponding to the adjusting unit 400 and the second column unit 200, and can support the first end of the support beam assembly 310.

[0094] Specifically, the adjusting unit 400 is located between the first end of the support beam assembly 310 and the first column unit 100. Please continue to refer to Figure 3 and Figure 4As shown, the adjusting unit 400 comprises a fixed part 410 and a moving part 420, the fixed part 410 is connected with the rotating assembly 120, and the moving part 420 is in abutment with the first end of the support beam assembly 310. The moving part 420 is detached from the fixed part 410, the distance between the moving part 420 and the fixed part 410 is increased, and then the moving part 420 is connected with the fixed part 410. Since the fixed part 410 is connected with the rotating assembly 120, and the moving part 420 is in abutment with the first end of the support beam assembly 310, the increase of the distance between the moving part 420 and the fixed part 410 can increase the distance between the first end of the support beam assembly 310 and the rotating assembly 120. Since the moving part 420 is in abutment with the first end of the support beam assembly 310, the moving part 420 can support the first end of the support beam assembly 310 at a preset position (wherein the preset position refers to the position corresponding to the included angle between the support beam assembly 310 and the rotating assembly 120 after the adjustment). The process of reducing the distance between the first end of the support beam assembly 310 and the rotating assembly 120 is opposite to the process of increasing the distance between the two, which will not be described here.

[0095] When the height of the second end of the support beam assembly 310 is less than the height of the support part on the second column unit 200, the support beam assembly 310 is swung upward around the second axis L2, and then the distance between the support beam assembly 310 and the second column unit 200 is increased by increasing the distance between the moving part 420 and the fixed part 410, and the support beam assembly 310 is supported at a preset position by the supporting action of the moving part 420, so that the included angle between the support beam assembly 310 and the second column unit 200 can be increased, thereby increasing the height of the second end of the support beam assembly 310.

[0096] When the height of the second end of the support beam assembly 310 is greater than the height of the support part on the second column unit 200, the support beam assembly 310 is swung downward around the second axis L2, and then the distance between the support beam assembly 310 and the second column unit 200 is reduced by reducing the distance between the moving part 420 and the fixed part 410, and the support beam assembly 310 is supported at a preset position by the supporting action of the moving part 420, so that the included angle between the support beam assembly 310 and the second column unit 200 can be reduced, thereby reducing the height of the second end of the support beam assembly 310.

[0097] The rail support provided by the present application comprises a first column unit 100, a second column unit 200, a support beam unit 300 and an adjusting unit 400. The support beam unit 300 comprises at least two support beam assemblies 310. The first column unit 100 comprises at least two rotating assemblies 120, which are hinged to the first ends of the support beam assemblies 310, so that the support beam assemblies 310 can swing up and down in the plane formed by the support beam assemblies 310 and the first column unit 100. The distance between the fixed part 410 and the moving part 420 in the adjusting unit 400 can be changed, and the moving part 420 can also be used to support the first ends of the support beam assemblies 310. By swinging the support beam assemblies 310 relative to the first column unit 100, the included angle between the support beam assemblies 310 and the first column unit 100 can be changed. Then, by changing the distance between the moving part 420 and the fixed part 410, the distance between the first ends of the support beam assemblies 310 and the first column unit 100 can be changed, and by supporting the first ends of the support beam assemblies 310 at the preset positions by the moving part 420, the height of the second ends of the support beam assemblies 310 can be changed, so that the second ends of the support beam assemblies 310 can be lapped on the second column unit 200.

[0098] Next, the specific way of adjusting the distance between the moving part 420 and the fixed part 410 will be described.

[0099] The distance between the moving part 420 and the fixed part 410 can be increased in various ways. In some embodiments, the distance between the moving part 420 and the fixed part 410 can be increased by adding a gasket between the moving part 420 and the fixed part 410.

Figures 3 to 5 As shown in the present embodiment, in order to facilitate the operation of adjusting the distance, the fixed part 410 is the first wedge, and the moving part 420 is the second wedge matched with the first wedge. The wedge surfaces of the first wedge and the second wedge are in abutment, and the second wedge slides upward along the inclined direction of the wedge surface of the first wedge to increase the distance between the first ends of the support beam assemblies 310 and the fixed part 410.

[0101] Specifically, the dimension of the first wedge along the first direction X is referred to as the first wedge thickness, which gradually decreases from top to bottom along the second direction Y to form the first wedge surface 411 on the side of the first wedge facing the second wedge.

[0102] The dimension of the second wedge along the first direction X is referred to as the second wedge thickness, which gradually increases from top to bottom along the second direction Y to form the second wedge surface 421 matched with the first wedge surface 411 on the side of the second wedge facing the wedge.

[0103] On the same horizontal line, the sum of the first wedge thickness and the second wedge thickness is the distance between the first end of the support beam assembly 310 and the first column unit 100, which is called the distance D. The distance D can be changed with the movement of the second wedge relative to the first wedge.

[0104] When it is needed to increase the distance D, the second wedge is slid upward along the first wedge surface 411 (or the second wedge surface 421), the sum of the first wedge thickness and the second wedge thickness is increased, and thus the distance D is increased. When it is needed to decrease the distance D, the second wedge is slid downward along the first wedge surface 411 (or the second wedge surface 421), the sum of the first wedge thickness and the second wedge thickness is decreased, and thus the distance D is decreased.
