DETAILED DESCRIPTION

[0035] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0036] Example One

[0037] In a typical embodiment of the present application, referring to Figures 1-7 , a support structure for rail transportation is composed of a base component 1, a column 2, a cross brace 3, a top cover 4, a stop block component 5, a spring 6, a pressing assembly 7 and the like. The cross brace 3 is installed between a pair of columns 2, and the steel rail 17 can be vertically lapped on the cross brace 3 and evenly arranged. The column 2 can limit the sliding of the steel rail 17 to the two sides, ensuring that the steel rail 17 will not be subjected to unbalanced load. The top cover is used to press the cross brace to prevent the vertical movement of the steel rail during transportation.

[0038] As shown in Figure 4 , the base component 1 is of a frame structure, and at least two pairs of columns 2 are provided at the top. A plurality of mounting holes 101 are provided at the bottom of the base component 1, and the base component 1 can be installed and fixed on the vehicle body by means of bolts and container locks to fix the base component on the vehicle body.

[0039] The top of the base component 1 is provided with two pairs of mounting grooves 102, which are circular groove structures for adapting to the columns. The four mounting grooves 102 are distributed at the four corners of the base component, and the two mounting grooves 102 along the length direction of the base component 1 form a pair, each pair of mounting grooves is used to install a first column and a second column, the first column and the second column form a pair of columns 2, and the two columns 2 are used to install the cross brace 3, so that the length direction of the cross brace 3 is the same as the length direction of the base component 1.

[0040] As shown in Figure 2 , the column 2 is of a circular tube structure, with an outer diameter of φ20-φ800. The four column structures are the same, and the column 2 is assembled at the mounting groove 102. The mounting groove 102 and the column 2 can be welded and fixed, or fixed by bolts through the provision of threaded holes 302 and the like. The top of the column 2 is open, and the inner end is provided with an internal thread structure for cooperation with the first locking screw 11.

[0041] A cross brace is installed between the first column and the second column on each pair of columns, and the cross brace is arranged along the height direction of the column, and multiple layers can be provided, thereby realizing the placement of multiple layers of steel rails. Each pair of columns on the base assembly is arranged along the length direction of the base and located at both ends of the base assembly.

[0042] As shown in Figure 5 , the cross brace 3 is in the form of a support rod, one end of which is provided with a circular opening 301, the inner diameter of which is matched with the outer diameter of the column 2, for sleeving on the column 2, and the other end is provided with a threaded hole 302 on the side surface, for fixedly cooperating with the block seat 8. The length of the cross brace 3 is matched with the distance between each pair of columns. The cross brace 3 is provided with a handle 303 on the side surface, by which the cross brace can be pulled. When the steel rail is assembled, the cross brace is rotated around the circular opening 301 as the center by the handle 303.

[0043] As shown in Figure 7 , the block assembly 5 includes a block seat 8 and a block 9. The block seat includes a cylindrical sleeve, and a limiting plate is arranged on the outer side of the sleeve. The limiting plate is formed by welding an arc-shaped plate matched with the outer side of the sleeve and a flat plate, and the arc-shaped plate of the limiting plate is integrally welded with the sleeve. The structure of the block 9 is the same as that of the limiting plate. The end of the cross brace provided with the threaded hole is rotated to the limiting plate and abuts against the limiting plate. The flat plate on the limiting plate and the block 9 is provided with a threaded hole. The limiting plate and the block are used for clamping the end of the cross brace. When the threaded hole of the cross brace 3 is aligned with the threaded hole of the flat plate, the cross brace is fixed by the bolt 10, as shown in Figure 2 .

[0044] As shown in Figure 1 and Figure 3 , four groups of cross braces 3 and one group of top covers 4 are arranged on the two pairs of columns 2 of the embodiment. The four groups of cross braces are installed between each pair of columns, and the cross braces can slide up and down along the columns by the arrangement of the opening 301 and the block assembly 5. The top cover 4 is located above the cross brace 3 and is also installed between the first column and the second column, for limiting the vertical movement of the steel rail below.

[0045] When the cross brace 3 is installed, one end of the four groups of cross braces 3 is sleeved on the first column through the opening 301 between each group of columns, and the second column is sleeved with four block seats 8. Springs are arranged between cross braces 3 of different layers.

[0046] Specifically, the first column of each pair of columns 2 is rotationally matched with one end of the cross brace 3, and the block seat 8 is sleeved on the second column to fix the other end of the cross brace. Multiple layers of steel rail installation spaces are formed between different cross braces 3 and between the cross brace and the base assembly. Springs are sleeved on the columns at both ends of the installation space.

[0047] As shown in Figure 1As shown, the first layer of cross braces 3 and the top surface formed by the base constitute a first layer of mounting space from bottom to top, and springs 6 are mounted on the columns between the first layer of cross braces and the base. Springs are also sleeved on the columns between different cross braces, and each pair of columns 2 is sleeved with eight groups of springs.

[0048] The springs 6 are arranged to limit the height direction and also reduce the vibration of the rails during transportation. In other examples, more than four layers of mounting space for rails can be provided.

[0049] As shown, Figure 6 The top cover 4 is a long strip structure with an arch shape at the top, and is used to fix the rails between each pair of columns 2 after installation. A pressing assembly is provided between the top cover 4 and the uppermost cross brace 3.

[0050] One end of the top cover 4 is sleeved around the outer side of the first column at the top end, and a bearing 15 is provided to allow the top cover to rotate relative to the first column, reducing friction when rotating around the column. The other end of the top cover is fixed to the second column through a fixing structure.

[0051] It should be noted that the fixing structure at the other end of the top cover 4 can also be a fixed form composed of a stop block. In other examples, a semi-arc structure is provided at the other end of the top cover 4, which can be used in cooperation with the limiting plate structure in the stop block assembly to fix the end of the top cover 4 on the column 2.

[0052] As shown, Figure 3 and Figure 6 The top cover 4 and the uppermost cross brace are provided with a plurality of locking screw holes in the length direction in sequence, which are used in cooperation with the second locking screw 12.

[0053] In a preferred example, a threaded seat is mounted on the upper surface of the uppermost cross brace for cooperation with the second locking screw 12. In this case, the threaded hole can not be provided on the uppermost cross brace.

[0054] In this example, a threaded seat is mounted on the upper surface of the uppermost cross brace 3, and a threaded hole is provided at the same time, so that the second locking screw 12 passes through the uppermost cross brace and a nut is mounted on the lower surface of the cross brace to achieve compression locking.

[0055] As shown, Figure 3 The top end of the column 2 is used in cooperation with the first locking screw 11, and the rod portion of the first locking screw 11 is used to extend into the column and cooperate with the threaded structure inside the column 2.

[0056] The first locking screw 11 is provided with a threaded head, which is used to abut against both ends of the top cover 4. After the top cover is installed, the first locking screw 11 is installed, and the threaded head presses the top cover 4, so that the top cover 4 cannot move upward.

[0057] After the four layers of steel rails 17 are installed, the compression and fixation of the loaded steel rails need to be achieved by the compression assembly to prevent the vertical movement of the steel rails during transportation. The compression assembly includes the jacks 14 arranged between the top cover and the uppermost layer of cross supports. The jacks 14 are arranged at the bottom of the top cover along the length direction, and the ends of the jacks 14 are fixed at the bottom of the top cover, with the output ends pointing to the cross supports and being capable of pressing the cross supports. After being pressed into place, the second locking screw 12 and the corresponding nut 13 are installed. At this time, the steel rail 17 is assembled, and the jacks 14 can be removed or retained.

[0058] The cross support groups used between different layers are detachable structures and are interchangeable.

[0059] The top cover 4 and the cross support 3 of the embodiment can be rotated by a certain angle around one of the columns 2 to one side during the loading and unloading of the steel rails, thereby ensuring that the loading and unloading of the steel rails between different layers are not affected.

[0060] The top of the cross support 3 is provided with a pad 16, which can be made of rubber, composite material, plastic, high polymer material or nanometer material, and has good wear resistance, corrosion resistance and aging resistance.

[0061] The device has simple structure, strong universality and good reliability, and can meet the transportation needs of long steel rails and other goods. During transportation, the steel rails 17 are limited by the columns 2, and the steel rails are evenly arranged on the cross supports or the base groups, so that the eccentric load does not occur; at the same time, the spacer iron is not needed, the operation is convenient, and the work efficiency and loading efficiency are improved. Through the setting of the top cover 4, the problem of unstable reinforcement and vertical movement of the steel rails 17 during transportation is solved.

[0062] Embodiment Two

[0063] In a typical embodiment of the present application, referring to Figures 1-7 Fig. 1, a method for assembling a support structure for steel rail transportation is provided, which uses the support structure for steel rail transportation of embodiment one, and includes the following steps:

[0064] The loading of the multi-layer steel rails is in a bottom-up manner. Before loading, the locking screw 11 is removed, the fixed ends of the cross supports 3 and the top cover 4 are unlocked, all the cross supports 3 and the top cover 4 are rotated to one side of the vehicle body around the first column, as shown in Figure 2 Fig. 2, to ensure that the loading of the steel rails is not affected, and then the steel rails are placed layer by layer. The number of steel rails placed in each layer can be 12. The first layer of steel rails is arranged on the base group, and the length direction of the steel rails is perpendicular to the length direction of the base group. The end of the steel rail can be overlapped on the base group, and the base group can also support the middle position of the steel rail. In actual transportation, according to the length of the steel rail, a different number of support structures for steel rail transportation are selected and arranged evenly.

[0065] After the first layer of the track is laid, the upper cross support is turned to the position where it can be connected to the second column, and the block group 5 composed of the block seat 8 and the block 9 is connected by the bolt 10. After locking and fixing, the remaining three layers of the track are loaded in turn. After the four layers of the track are loaded, the uppermost cross support is turned to the position where it can be connected to the second column and is fixed.

[0066] Then, one end of the top cover 4 provided with the bearing 15 is rotated around the column to the second column, and the column and the top cover 4 are fixed by the fixing structure. At this time, the first locking screw 11 is tightened to ensure reliable connection. The bolt head of the first locking screw is used to press the end of the top cover to prevent the top cover from moving upward along the column.

[0067] Then, the jack is installed. With the force of the jack with a pressure gauge, the force is within a reasonable range, the jack is supported by the top cover, and the uppermost cross support is pressed downward, and the cross support group 3 and the spring 6 between different layers are continuously compressed, so that the loaded track is locked and fixed. Then, the second locking screw 12 can be tightened by an electric tool, and the nut 13 is tightened, and the loading of the track is completed. When the track is unloaded, the reverse operation can be performed.

[0068] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
