Description

Technical Field

[0001] This invention belongs to the field of railway freight transportation technology, and more specifically, relates to a long rail transportation device. Background Technology

[0002] The construction of railway infrastructure requires a large number of steel rails. The transportation of long steel rails is an essential part of the railway infrastructure construction process. Long steel rails are usually transported using multiple sets of flatcars.

[0003] Currently, when transporting multiple long steel rails, they are placed side by side on multiple flatcars, forming a single unit. This makes it difficult to move the rails on multiple flatcars, increasing the rigidity of the entire long rail. As a result, when the flatcars pass through curved roads, adjacent flatcars cannot deviate too much, causing the vehicle to be unable to pass through curved roads smoothly, and even leading to the phenomenon of multiple flatcars overturning as a whole.

[0063] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0064] Please refer to the following: Figures 1 to 3 The long rail transport equipment provided by the present invention will now be described. The long rail transport equipment includes a first flatcar 1, a second flatcar 2, a first bearing plate 11, a second bearing plate 21, and multiple sets of fastening components 3.

[0065] The head of the second flatcar 2 is hinged to the tail of the first flatcar 1; the first bearing plate 11 is rotatably disposed in the middle of the first flatcar 1 in the up-down direction, and is used to support one end of the rail 8; the second bearing plate 21 is slidably disposed on the second flatcar 2 in the front-back direction, and is used to support the other end of the rail 8; wherein, the top of the first bearing plate 11 and the second bearing plate 21 are respectively covered with multiple sets of fastening components 3, and the fastening components 3 are used to fasten the rail 8.

[0066] The first flatcar 1 and the second flatcar 2 are both set on the train track. Multiple steel rails 8 are hoisted onto the first flatcar 1 and the second flatcar 2 by a crane and are arranged side by side. After the two ends of the steel rails 8 rest on the first bearing plate 11 and the second bearing plate 21 respectively, they extend forward of the first flatcar 1 and backward of the second flatcar 2 respectively. After the steel rails 8 are loaded, the multiple steel rails 8 are covered by fastening components 3, and the fastening components 3 abut against the top surface of the multiple steel rails 8, firmly fixing the multiple steel rails 8 on the first bearing plate 11 and the second bearing plate 21, preventing the steel rails 8 from slipping or falling, and also preventing the steel rails 8 from jumping when encountering bumpy sections during transportation, thus ensuring the stability of the steel rails 8 during transportation.

[0067] Specifically, a bushing 112 is provided in the middle of the bottom surface of the first support plate 11. The bushing 112 is a cylindrical structure with a diameter of 160mm, a wall thickness of 10mm, and a height of 105mm. One end of the bushing 112 is connected to the middle of the bottom surface of the first support plate 11 by welding. A vertical rotating shaft is welded to the center of the first flatcar 1. The bushing 112 is fitted onto the rotating shaft to achieve the rotation effect of the first support plate 11. When installing the first support plate 11, the bushing 112 can be directly fitted onto the rotating shaft.

[0068] Compared with the prior art, the long rail transport equipment provided by the present invention, by rotating the first bearing plate 11 on the first flatcar 1 and sliding the second bearing plate 21 on the second flatcar 2, allows multiple rails 8 to move relative to each other on the first flatcar 1 and the second flatcar 2 when the first flatcar 1 and the second flatcar 2 rotate relative to each other. This adapts to the offset angle of the first flatcar 1 and the second flatcar 2, enabling the flatcar to transport more rails 8, thereby improving the transport efficiency and safety of the rails 8.

[0069] In some embodiments, the first support plate 11 and the second support plate 21 described above can be adopted as follows: Figures 2 to 5 The structure shown. See also Figures 2 to 5Both the first support plate 11 and the second support plate 21 are elongated strips; the length direction of the second support plate 21 is the front-rear direction of the second flatcar 2; a plurality of first rollers 111 are arranged on the bottom wall of the first support plate 11; the plurality of first rollers 111 are rolled on the first flatcar 1; a plurality of second rollers 211 are arranged on the bottom wall of the second support plate 21; the plurality of second rollers 211 are rolled on the second flatcar 2.

[0070] Specifically, both the first bearing plate 11 and the second bearing plate 21 are integral structures, each made of 7mm thick steel plate pressed into a cold-formed channel steel structure measuring 2220mm×400mm×63mm×7mm. Two sets of fastening components 3 are respectively installed on the first bearing plate 11 and the second bearing plate 21, and two support plates 13 are respectively installed on the first bearing plate 11 and the second bearing plate 21. The support plates 13 are made of 80mm×43mm×5mm hot-rolled channel steel and are connected to the first bearing plate 11 and the second bearing plate 21 by welding. The length direction of the support plates 13 is the same as that of the first bearing plate 11 and the second bearing plate 21, and each set of fastening components 3 is mounted on one support plate 13. When loading the rail 8, the rail 8 is placed on the support plate 13. The support plate 13 increases the thickness of the first bearing plate 11 and the second bearing plate 21, thereby improving their load-bearing capacity.

[0071] The first roller 111 has a taper of 1:50, a maximum outer diameter of 76 mm, and a height of 70 mm. Multiple sets of mounting seats are arranged along the length of the first bearing plate 11 below it. Each set of mounting seats includes two vertically and parallelly arranged mounting plates 113. The mounting plates 113 are 20 mm thick, 390 mm long, and 96 mm wide. The distance between the two mounting plates 113 is 100 mm. A connecting hole is provided at the lower part of the mounting plates 113 along the length of the first bearing plate 11. A first mounting shaft 1111 is inserted through the first roller 111 along its left-right direction. The first mounting shaft 1111 passes through the connecting hole along the length of the first support plate 11. The first mounting shaft 1111 is 165mm long and 20mm in diameter. A mounting hole with a diameter of 5mm is opened perpendicular to its axial direction at one end of the first mounting shaft 1111, and a cotter pin is inserted into the mounting hole. A stop block 1112 is provided at the other end of the first mounting shaft 1111, which, together with the cotter pin, limits the rotating shaft to the first support plate 11. When the first roller 111 needs to be replaced, the cotter pin is pulled out from the mounting hole, and then the first mounting shaft 1111 is pulled out from the connecting hole, thus disassembling the first roller 111. The disassembly process is convenient. The tapered first roller 111 rolls more smoothly when the first support plate 11 rotates, and also prevents the first support plate 11 from squeezing and damaging both ends of the first roller 111 when rotating. To avoid confusion in the drawings, the mounting hole and the connecting hole are not shown in the figures.

[0072] The second roller 211 is mounted on the second bearing plate 21 via the second mounting shaft 2111 and a cotter pin. The first mounting shaft 1111 and the second mounting shaft 2111 have the same shape but different dimensions. The second roller 211 is mounted in the same way as the first roller 111, which will not be described in detail here.

[0073] To improve the stability of the first bearing plate 11 during rotation, multiple sets of first rollers 111 can be provided along the width direction of the first bearing plate 11. To improve the stability of the second bearing plate 21 during rotation, multiple sets of second rollers 211 can be provided along the width direction of the second bearing plate 21.

[0074] It should be noted that the distance between the first bearing plate 11 and the first flatcar 1 is not less than 8mm to ensure that the first roller 111 and the second roller 211 roll normally.

[0075] In some embodiments, the above-mentioned long rail transport equipment adopts, for example... Figure 3 and Figure 5 The structure shown. See also Figure 3 and Figure 5 The long rail transport equipment also includes a guide mechanism 4, which includes multiple connecting frames 41 and multiple sets of baffle assemblies 42.

[0076] Multiple connecting frames 41 are evenly arranged along the length of the second support plate 21. The connecting frames 41 are arranged in an inverted U-shape on the bottom wall of the second support plate 21. Multiple second rollers 211 are rotatably arranged in the cavity of the connecting frame 41. Multiple sets of baffle assemblies 42 are evenly arranged along the length of the second support plate 21 and correspond to the multiple connecting frames 41. The baffle assemblies 42 are covered on the second flatcar 2, and the baffle assemblies 42 and the top wall of the second flatcar 2 form a guide cavity 421. The top of the guide cavity 421 has an opening. The connecting frame 41 passes downward through the corresponding opening and extends into the guide cavity 421.

[0077] Specifically, the connecting frame 41 is welded to the bottom of the second bearing plate 21. The second roller 211 is mounted in the cavity of the connecting frame 41 via a second mounting shaft 2111 and a cotter pin. The diameter of the second mounting shaft 2111 is 10mm. The second roller 211 is a cylindrical cast iron roller with a diameter of 80mm and a thickness of 30mm. The connecting frame 41 has a width of 82mm, a height of 74mm, a length of 400mm, and a base material thickness of 5mm, wherein the length of the connecting frame 41 is equal to the width of the second bearing plate 21. By placing the second roller 211 in the cavity of the connecting frame 41, the second roller 211 is protected from damage caused by external impacts.

[0078] The top wall of the second flatcar 2 has multiple guide grooves 23 extending in the front-rear direction, and the multiple guide grooves 23 are evenly arranged in the left-right direction of the second flatcar 2; multiple second rollers 211 are respectively located in the multiple guide grooves 23; wherein, the two sides of the second rollers 211 have a first inclined surface; the two side walls of the guide grooves 23 have second inclined surfaces that correspond to and fit with the first inclined surfaces. Setting the second rollers 211 in the guide grooves 23 can make the second rollers 211 more stable when rolling.

[0079] Specifically, the guide groove 23 is a rectangular groove of 800mm × 40mm × 10mm. By having a first inclined surface at both sides of the second roller 211 and a second inclined surface on the guide groove 23, the friction between the second roller 211 and the guide groove 23 is reduced, making the second roller 211 slide more smoothly.

[0080] In some embodiments, the baffle assembly 42 described above employs, for example... Figure 5 The structure shown. See also Figure 5 The baffle assembly 42 includes two baffles 422 and two sealing plates 423.

[0081] Two baffles 422 are set on the second flatcar 2 and are symmetrically located on both sides of the connecting frame 41. The length of the baffles 422 is 800mm. Two sealing plates 423 are symmetrically arranged on both sides of the connecting frame 41. One end of the sealing plate 423 is set on the top of the corresponding baffle 422, and the other end is attached to the side wall of its corresponding connecting frame 41.

[0082] Specifically, the baffle 422 has an L-shaped structure and is fixed to the second flatcar 2 by bolts, and is symmetrically distributed on both sides of the guide groove 23. After the sealing plate 423 is connected to the baffle 422, it seals the second roller 211 and the guide groove 23, which can effectively prevent rain and snow from damaging the connecting frame 41 and the second roller 211, and improve the service life of the connecting frame 41 and the second roller 211.

[0083] In some embodiments, the guide mechanism 4 described above adopts, for example... Figure 5 The structure shown. See also Figure 5 The guide mechanism 4 also includes two sets of rollers 43.

[0084] Two sets of rollers 43 are connected to the left and right sides of the bottom of the connecting frame 41 respectively, and are also rolled on the two baffles 422 along the front and rear direction of the second flatcar 2 respectively.

[0085] Specifically, a side lug is connected to the left and right sides of the bottom of the connecting frame 41, and two rollers are respectively rotatably mounted on the side lugs. When the first bearing plate 11 slides, the roller 43 slides on the baffle 422, which plays a role in balancing the connecting frame 41 and making the second bearing plate 21 more stable when it moves.

[0086] In one possible implementation, the fastening component 3 described above adopts the following... Figure 2 and Figure 3 The structure shown. See also Figure 2 and Figure 3 The fastening assembly 3 includes a first support 31, a second support 32, and a fastening plate 33.

[0087] The first support 31 is disposed on the first bearing plate 11 / second bearing plate 21; the second support 32 is disposed on the first bearing plate 11 / second bearing plate 21; the first support 31 and the second support 32 are arranged along the length direction of the first bearing plate 11 / second bearing plate 21; one end of the fastening plate 33 is hinged to the first support 31, and the other end is fixed to the second support 32 by bolts; the fastening plate 33 and the first bearing plate 11 / second bearing plate 21 form a bearing space, and the rail 8 is located in the bearing space.

[0088] Multiple sets of fastening components 3 can be provided on the first support plate 11 and the second support plate 21, but the optimal solution is to provide two sets of fastening components 3 on the first support plate 11 and the second support plate 21 respectively, with the two sets of fastening components 3 arranged along the length direction of the first support plate 11 / second support plate 21.

[0089] Specifically, taking the first support 31 and the second support 32 mounted on the first bearing plate 11 as an example, the two first supports 31 are respectively fixed to both ends of the first bearing plate 11 with bolts, and the two second supports 32 are fixed between the two first supports 31 with bolts. To save space on the first bearing plate 11, the two second supports 32 can be connected together to form a whole. Mounting grooves 311 and fixing grooves 321 are respectively provided on the top of the first supports 31 and the second support 32. Both mounting grooves 311 and fixing grooves 321 have two side openings along the left-right direction of the first bearing plate 11, and also have a front opening or a rear opening along the front or rear of the first bearing plate 11. A shaft hole penetrating the mounting groove 311 is provided on the top of the first support 31 along the vertical direction, and a fixing hole penetrating the fixing groove 321 is provided on the top of the second support 32 along the vertical direction; the fixing hole is a threaded hole.

[0090] The fastening plate 33 has holes at both ends corresponding to the mounting holes and fixing holes, respectively. The fastening plate 33 is rotatably connected to the first support 31 via a pin 34. When connecting the fastening plate 33 to the first support 31, the pin 34 is passed through the mounting hole and the corresponding hole on the fastening plate 33 from top to bottom. When fixing the fastening plate 33 to the second support 32, the bolt is passed through the fixing hole and the corresponding hole on the fastening plate 33 from top to bottom. The connection method between the fastening plate 33 and the first support 31 and the second support 32 is simple and quick, facilitating the maintenance and replacement of the fastening plate 33.

[0091] A layer of rubber sheet can be covered on the bottom wall of the fastening plate 33. The rubber sheet is attached to the top of the rail 8, which solves the problem of damage to the rail 8 caused by the fastening plate 33 during the bumping of the first flatcar 1 and the second flatcar 2.

[0092] Before loading the rails 8, the fastening plate 33 is separated from the first support 31, and the fastening plate 33 is rotated so that its length direction is perpendicular to the length direction of the first bearing plate 11, so as to avoid the fastening plate 33 obstructing the loading of the rails 8. During the loading process, the rails 8 are loaded simultaneously from the left and right sides of the first flatcar 1, and the rails 8 are loaded sequentially from the inside to the outside, so that each bearing space can accommodate five rails 8 respectively.

[0093] The installation methods of the steel rail 8 and fastening assembly 3 on the second bearing plate 21 are the same, and will not be elaborated further here. To avoid confusion in the attached drawings, the fixing holes and mounting holes are not specifically marked in the drawings.

[0094] In one possible implementation, the aforementioned long rail transport equipment also employs, for example... Figure 1 , Figure 6 and Figure 7 The structure shown. See also Figure 1 , Figure 6 and Figure 7 The front of the first flatcar 1 is provided with an arc-shaped guide rail 12, the center of which is the rotation axis of the first bearing plate 11; the long rail transport equipment also includes a first limiting component 5, which includes a first limiting sleeve 51 and a slide 52.

[0095] The first limiting sleeve 51 is installed on one end of the multiple steel rails 8; the bottom of the slide block 52 is slidably set on the arc-shaped guide rail 12, and the top is connected to the first limiting sleeve 51.

[0096] Specifically, to improve the stability of the slide block 52 during sliding, multiple sets of arc-shaped guide rails 12 can be set on the first flat car 1 along its front-back direction.

[0097] During the operation of the first flatcar 1 and the second flatcar 2, downhill situations are likely to occur. Therefore, the rails 8 loaded on the first flatcar 1 and the second flatcar 2 will slide forward under the action of gravity, which may cause them to collide with the front of the car. Therefore, by covering the front end of the rail 8 with the first limiting sleeve 51 and connecting it to the first flatcar 1 through the slide seat 52, the rail 8 is prevented from moving forward, thus improving the safety of the rail 8 during transportation. In particular, by opening an arc-shaped guide rail 12 on the first flatcar 1, the first limiting sleeve 51 can prevent the rail 8 from sliding forward while meeting the requirements for the rotation of the first bearing plate 11. Furthermore, the arc-shaped guide rail 12 has a certain limiting effect on the slide seat 52, preventing the slide seat 52 from moving forward.

[0098] It should be noted that when transporting rail 8, the locomotive pulls the first flatcar 1 and the second flatcar 2 in sequence. The first flatcar 1 is in front of the second flatcar 2. Therefore, the direction of movement from the second flatcar 2 to the first flatcar 1 is defined as forward, and the direction of movement from the first flatcar 1 to the second flatcar 2 is defined as backward.

[0099] In some embodiments, the above-mentioned long rail transport equipment also employs, for example... Figure 1 and Figure 8 The structure shown. See also Figure 1 and Figure 8 The long rail transport equipment also includes a second limiting component 6, which includes a second limiting sleeve 61, two sets of support seats 62, two sets of guide wheels 63, two sets of second pull ropes 65 and a first pull rope 64.

[0100] The second limiting sleeve 61 is installed on the other end of the multiple rails 8; two sets of support seats 62 are respectively installed at the left and right ends of the second bearing plate 21; two sets of guide wheels 63 are respectively installed on the top of the two sets of support seats 62 and rotate in the left and right directions of the second bearing plate 21; one end of the two sets of second pull ropes 65 is connected to the top of the second limiting sleeve 61, the middle part is respectively connected to the two sets of guide wheels 63, and the other end is connected to the second bearing plate 21; one end of the first pull rope 64 is connected to the bottom of the second limiting sleeve 61, and the other end is connected to the second bearing plate 21.

[0101] During the transportation of rail 8, uphill sections are encountered. To prevent rail 8 from sliding downhill or even detaching from the second flatcar 2, a second limiting sleeve 61 is fitted onto the rear end of rail 8. The bottom and top ends of the second limiting sleeve 61 are fixed to the second bearing plate 21 by a first pull rope 64 and a second pull rope 65, respectively. Since the second bearing plate 21 can move freely on the second flatcar 2, connecting the second limiting sleeve 61 directly to the second bearing plate 21 will cause rail 8 to abut against the second limiting sleeve 61, directly pulling the second bearing plate 21 to move along the front-back direction of the second flatcar 2, and even causing the second bearing plate 21 to detach from the second flatcar 2. Therefore, support seats 62 are set at both ends of the second bearing plate 21, and guide wheels 63 are set on the top of the support seats 62. After the second pull rope 65 is guided by the second guide wheel, it is then connected to the second bearing plate 21. The two bearing plates 21 are connected so that after the steel plate abuts against the second limiting sleeve 61, the second limiting sleeve 61 pulls the second pull rope 65, so that the pulling force of the second pull rope 65 on the second bearing plate 21 is vertical. As a result, when the second pull rope 65 pulls the second bearing plate 21, the second bearing plate 21 tilts along the front and rear direction of the second flatcar 2. Since the guide assembly covers the roller 43 inside it, after the second bearing plate 21 tilts, the upper side of the roller 43 will abut against the sealing plate 423 to prevent the second bearing plate 21 from sliding.

[0102] By installing a second limiting sleeve 61 at the rear end of the rail 8, and connecting the first pull rope 64 and the second pull rope 65 to the second bearing plate 21, and especially by guiding the second pull rope 65 with the guide wheel 63, the second bearing plate 21 can be fastened to the second flatcar 2 when the rail 8 slides backward, thus preventing the rail 8 from slipping off.

[0103] It should be noted that multiple first pull ropes 64 can be used, and the specific number can be freely controlled by the staff. The first pull rope 64 can limit the distance between the rear end of the rail 8 and the second bearing plate 21. The length of the first pull rope 64 should be slightly longer than the distance between the rear end of the rail 8 and the second bearing plate 21. When there is a shift between the first flatcar 1 and the second flatcar 2, it prevents the rail 8 from sliding too far along the front-back direction of the second flatcar 2.

[0104] In some embodiments, the above-mentioned long rail transport equipment adopts, for example... Figure 1 , Figures 8 to 10 The structure shown. See also Figure 1 , Figures 8 to 10 The second flatcar 2 has an inverted T-shaped limiting groove 22 extending along its front-back direction; the long rail transport equipment also includes a balancing component 7, which includes a connecting plate 71 and a slider 72.

[0105] One end of the connecting plate 71 is hinged to the front end of the second bearing plate 21; the second pull rope 65 is connected to the connecting plate 71; the slider 72 is located at the bottom of the connecting plate 71; the bottom of the slider 72 is provided with a limiting block 721, which is slidably located in the limiting groove 22 and fits against the inner wall of the limiting groove 22.

[0106] When the second flatcar 2 encounters an uphill slope, the rail 8 abuts against the second limiting sleeve 61 under the action of gravity. The second limiting sleeve 61 pulls the first pull rope 64 and the second pull rope 65. When the second pull rope 65 is pulled, the second pull rope 65 pulls the connecting plate 71 to rotate upward, thereby causing the limiting block 721 to abut against the top wall of the limiting groove 22, thereby fixing the second bearing plate 21 on the second flatcar 2 and preventing the rail 8 from sliding backward.

[0107] When the second bearing plate 21 is limited by the roller 43 and the sealing plate 423, the second bearing plate 21 will tilt. The fastening plate 33 presses the rail 8 onto the second bearing plate 21. Although it can prevent the second bearing plate 21 from tilting upward to a certain extent, the rail 8 is heavy. After it abuts against the second limiting sleeve 61, the squeezing force of the fastening plate 33 alone is insufficient to prevent the second bearing plate 21 from tilting. Moreover, it is easy to damage the second bearing plate 21, as well as the roller 43 and the sealing plate 423. To solve the above problems, a connecting plate 71 is hinged to the front end of the second bearing plate 21, and a slider 72 is connected to the bottom of the connecting plate 71. The force of the rail 8 is transferred to the connecting plate 71. Finally, the limiting block 721 abuts against the top wall of the limiting groove 22, and finally the force of the rail 8 falling backward is transferred to the second flatcar 2. While limiting the rail 8 from slipping, it also protects the fastening plate 33, the roller 43 and the sealing plate 423, and improves the service life of the equipment.

[0108] In some embodiments, the aforementioned limiting block 721 adopts, for example... Figure 1 , Figures 8 to 10 The structure shown. See also Figure 1 , Figures 8 to 10 There is a gap between the top wall of the limiting block 721 and the top wall of the limiting groove 22; the top wall of the limiting block 721 has a plurality of positioning teeth 7211 evenly arranged along the front and rear direction of the second flatcar 2, and the top wall of the limiting groove 22 has a plurality of positioning grooves 221 that cooperate with the positioning teeth 7211.

[0109] Because the friction between the limiting block 721 and the top wall of the limiting groove 22 is sufficient to prevent the rail 8 from detaching from the second flatcar 2 on a gentle slope, the friction alone is insufficient to ensure the second bearing plate 21 is securely mounted on the second flatcar 2 on a steep slope. By providing multiple positioning teeth 7211 on the top wall of the limiting block 721, after the second pull rope 65 pulls the connecting plate 71, the connecting plate 71 moves the limiting block 721 upward, causing the positioning teeth 7211 to insert into the positioning grooves 221 on the top wall of the limiting groove 22, thereby preventing the second bearing groove from moving in its front-back direction and achieving a stable positioning effect.

[0110] When the first flatcar 1 and the second flatcar 2 deviate, the first bearing plate 11 rotates and the second bearing plate 21 slides. Under the movement of the first bearing plate 11 and the second bearing plate 21, the rail 8 will move a short distance along the front-back direction of the second flatcar 2. To prevent the second flatcar 2 and the first flatcar 1 from triggering the balancing component 7 when the rail 8 moves through a curve, a gap is set between the limiting block 721 and the top wall of the limiting groove 22. When the rail 8 moves a short distance, the limiting block 721 moves upward but not enough to allow the positioning block to insert into the positioning groove 221. When the rail 8 moves too far, it indicates that the fastening plate 33 is loose, or the second flatcar 2 is going uphill. The positioning block inserts into the positioning groove 221, preventing the rail 8 from disengaging from the second bearing plate 21.

[0111] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
