[0058] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0059] In the present invention, unless otherwise clearly specified, terms such as "installation", "connection", "connection", "fixation" and the like shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral molding. It may be a mechanical connection, an electrical connection or communication with each other. It may be directly connected, or indirectly connected through an intermediate medium. It may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention may be understood according to specific circumstances.

[0060] During the construction of railways, rail transport vehicles are usually used to transport long rails; in order to carry long rails, a plurality of rail brackets are generally arranged at intervals along the length direction of the rails on the rail transport vehicle. The rail bracket includes a first column, a second column, a third column, and a plurality of support beams located between the first column and the second column; the first column and the second column are arranged at intervals in a direction perpendicular to the length direction of the rail, and the first column and the third column are arranged at intervals in the length direction of the rail; the center lines of the first column, the second column, and the third column are all perpendicular to the horizontal plane, and the plane where the first column and the second column are located and the plane where the first column and the third column are located are perpendicular to each other; one end of each support beam is hinged to the first column, and the hinge axis is parallel to the center line of the first column; support plates are arranged on both the second column and the third column, and the support plates are used to support one end of the support beam, and rotatable locking columns are arranged on both the second column and the third column, and a stop block is arranged at one end of the locking column; rotate the support beam until the other end of the support beam faces the support plate, and then twist the locking column so that the stop block rotates to one side of the support beam, and the stop block can prevent the support beam from rotating to realize the locking of the support beam; a plurality of installation grooves are arranged on each support beam, and the long rail is arranged in the installation grooves.

[0061] When the support beam is locked on the third column, the support beam is in an open state, and at this time it is used to load the long rail; when the support beam is locked on the second column, the support beam is in a closed state, and at this time the long rail is fixed on the rail bracket, and then the long rail can be transported.

[0062] However, during the transportation process, the shaking of the equipment easily causes the locking column to rotate, the locking column drives the stop block to rotate, and then the stop block is separated from the support beam, and the support beam is disengaged from the lock. At this time, the long rail is likely to fall, causing accidents.

[0063] This embodiment provides a rail bracket, in which an elastic member and a telescopic column connected to the second column are arranged on the second column, and the elastic member is connected to the telescopic column and the second column; a locking hole is arranged on the support beam, and the elastic member is used to drive the telescopic column to extend into the locking hole when the support beam rotates until the locking hole faces the telescopic column; during the transportation of the long rail, the telescopic column extends into the locking hole, thereby locking the support beam. Compared with the stop block locking the support beam, the support beam is not easily disengaged from the lock, improving the reliability of the support beam locking.

[0064] Figure 1 It is the front view of the rail bracket provided by the embodiment of the present invention; Figure 2 It is the right view of the second column in the rail bracket provided by the embodiment of the present invention; Figure 3 It is the right view of the third column in the rail bracket provided by the embodiment of the present invention. Refer to Figures 1 - 3The present embodiment provides a rail support 1, comprising a first column 10 and a second column 20 whose center lines are perpendicular to a horizontal plane, and a support beam 30 located between the first column 10 and the second column 20; wherein, one end of the support beam 30 is rotatably connected to the first column 10, and the rotation axis of the support beam 30 is arranged parallel to the center line of the first column 10. There are multiple ways in which one end of the support beam 30 is rotatably connected to the first column 10. For example, a hinge shaft is arranged on the first column 10, and the center line of the hinge shaft is arranged parallel to the center line of the first column 10. A mounting hole is arranged at one end of the support beam 30, and the hinge shaft is rotatably inserted into the mounting hole, and the support beam 30 is rotatably connected to the hinge shaft; one end of the support beam 30 can also be connected to the first column 10 by a hinge or a rotating shaft, which is not limited here.

[0065] A plurality of support beams 30 are arranged between the first column 10 and the second column 20. The plurality of support beams 30 are arranged at intervals along the direction of the center line of the first column 10. A plurality of mounting grooves are arranged on each support beam 30. The plurality of mounting grooves are arranged at intervals along a direction perpendicular to the center line of the first column 10. The mounting grooves are used to carry long rails.

[0066] Furthermore, a locking device 21 is provided on the second column 20, and the locking device 21 includes an elastic member and a telescopic column 212 that is telescopically connected to the second column 20, the center line of the telescopic column 212 is parallel to the center line of the second column 20, and the elastic member is connected to the telescopic column 212 and the second column 20; illustratively, a first mounting plate and a second mounting plate may be provided on the second column 20, the first mounting plate and the second mounting plate are spaced apart along the center line direction of the second column 20, and the first mounting plate, the second mounting plate and the center line of the second column 20 are perpendicularly arranged, and one end of the elastic member is connected to the first mounting plate; a guide hole facing the elastic member is opened on the second mounting plate, and the telescopic column 212 is inserted into the guide hole, and one end of the elastic member facing away from the first mounting plate is connected to one end of the telescopic column 212, and the elastic member is used to drive the telescopic column 212 to move along the direction of the center line of the second column 20, and the elastic member can be a spring or an elastic sleeve, a cylinder, etc., which is not limited to this.

[0067] The support beam 30 is provided with a locking hole 31. The elastic member is used to drive the telescopic column 212 to extend into the locking hole 31 when the support beam 30 rotates to face the telescopic column 212, thereby locking the support beam 30. Each support beam 30 corresponds to a locking device 21.

[0068] The rail bracket 1 provided in this embodiment further includes a third column 40, and the central axis of the third column 40 is vertically arranged with respect to the horizontal plane; the plane where the third column 40 and the first column 10 are located is perpendicular to the plane where the first column 10 and the second column 20 are located. A locking device 21 is also provided on the third column 40, which has the same structure as the locking device 21 provided on the second column 20, and will not be elaborated here.

[0069] In the implementation manner where a plurality of support beams 30 are arranged between the first column 10 and the second column 20, during the process of placing the long rail on the lower support beam 30, it is necessary to rotate the upper support beam 30 towards the third column 40 and lock the support beam 30 through the locking device 21 on the third column 40 (the support beam 30 is in the open state), so as to prevent the upper support beam 30 from rotating during the process of placing the long rail and affecting the operation.

[0070] Continue to refer to Figure 4 , when the support beam 30 is in the closed state (the support beam 30 is locked by the locking device 21 on the second column 20), the telescopic column 212 on the second column 20 extends into the locking hole 31 on the support beam 30 to lock the support beam 30. At this time, the long rail is fixed in the installation groove, and then the long rail can be transported.

[0071] Continue to refer to Figure 5 , when the support beam 30 is in the open state (the support beam 30 is locked by the locking device 21 on the third column 40), the telescopic column 212 on the second column 20 disengages from the locking hole 31 on the support beam 30, and the support beam 30 rotates around the rotation axis on the first column 10 until the locking hole 31 is aligned with the telescopic column 212 on the third column 40, and then the telescopic column 212 extends into the locking hole 31 to lock the support beam 30; at this time, the long rail can be loaded.

[0072] When loading the long rail, first push out the telescopic column 212 on the second column 20 from the locking hole 31. At this time, the support beam 30 can rotate around the rotation axis until the locking hole 31 is aligned with the telescopic column 212 on the third column 40, and then the telescopic column 212 extends into the locking hole 31 to lock the support beam 30. At this time, the support beam 30 is in the open state and the long rail can be loaded. After the long rail is loaded, push out the telescopic column 212 on the third column 40 from the locking hole 31. At this time, the support beam 30 rotates around the rotation axis to the second column 20. When the locking hole 31 is aligned with the telescopic column 212 on the second column 20, the telescopic column 212 extends into the locking hole 31 to lock the support beam 30. At this time, the support beam 30 is in the closed state and the long rail is fixed in the installation groove, and then the long rail can be transported.

[0073] The rail bracket 1 provided in this embodiment includes a first column 10 and a second column 20 whose centerlines are perpendicular to the horizontal plane, and a support beam 30 located between the first column 10 and the second column 20; one end of the support beam 30 is rotatably connected to the first column 10, and the rotation axis of the support beam 30 is arranged parallel to the centerline of the first column 10; a locking device 21 is provided on the second column 20, and the locking device 21 includes an elastic member and a telescopic column 212 that is telescopically connected to the second column 20. The centerline of the telescopic column 212 is parallel to the centerline of the second column 20, and the elastic member is connected to the telescopic column 212 and the second column 20; a locking hole 31 is provided on the support beam 30, and the elastic member is configured to drive the telescopic column 212 to extend into the locking hole 31 when the support beam 30 rotates to make the locking hole 31 face the telescopic column 212 directly; during the process of transporting the rail, the telescopic column 212 extends into the locking hole 31, thereby locking the support beam 30. Compared with locking the support beam 30 by a stop block, the support beam 30 is not easily disengaged from the lock, improving the reliability of locking the support beam 30.

[0074] Continue to refer to Figures 6 - 8 , in this embodiment, a support plate 22 that abuts against the bottom end of the support beam 30 is provided on the second column 20. A sleeve 23 is provided at the lower part of the support plate 22. A telescopic hole 221 that communicates with the sleeve 23 is provided on the support plate 22. The telescopic column 212 is arranged through the telescopic hole 221 and the sleeve 23; a stop portion is provided on the side wall of the telescopic column 212. The elastic member includes a spiral spring 211. The spiral spring 211 is sleeved on the telescopic column 212, and the top end of the spiral spring 211 abuts against the stop portion, and the bottom end of the spiral spring 211 is connected to the second column 20; with such an arrangement, it is convenient for the telescopic column 212 to accurately extend into the locking hole 31, and the telescopic column 212 is not easily disengaged from the locking hole 31, further improving the reliability of the locking device 21.

[0075] Among them, a support plate 22 that abuts against the bottom end of the support beam 30 is provided on the second column 20. The support plate 22 is arranged perpendicular to the centerline direction of the second column 20. The support plate 22 is fixedly connected to the second column 20. One end of the support plate 22 is bent downward along a direction perpendicular to the centerline of the telescopic column 212. With such an arrangement, it is convenient for the support beam 30 to rotate smoothly onto the support plate 22, and the support plate 22 plays a supporting role for the support beam 30.

[0076] A sleeve 23 is provided at the lower part of the support plate 22. An expansion hole 221 communicating with the sleeve 23 is provided on the support plate 22. The expansion column 212 is arranged in the expansion hole 221 and the sleeve 23. A stop portion is provided on the side wall of the expansion column 212. Exemplarily, the stop portion can be a retaining ring sleeved on the expansion column 212, or a baffle can be provided on the outer wall of the expansion column 212, and there is no limitation thereto. The elastic member includes a helical spring 211. The helical spring 211 is sleeved on the expansion column 212, and the top end of the helical spring 211 abuts against the stop portion. The bottom end of the helical spring 211 is connected to the second upright column 20. At this time, the stop portion limits the helical spring 211.

[0077] For the rail bracket 1 provided in this embodiment, the expansion column 212 includes a first column body 2121 at the top end and a second column body 2122 at the bottom end. The cross-sectional area of the first column body 2121 is larger than that of the second column body 2122; the stop portion includes a stop tube 213. The stop tube 213 is sleeved on the second column body 2122, and a stop flange 2131 extending inward is provided at the top end of the stop tube 213. The stop flange 2131 abuts against the first column body 2121; the top end of the helical spring 211 is located in the stop tube 213 and abuts against the stop flange 2131; with such a setting, the stop tube 213 guides the expansion column 212, thereby improving the accuracy of the expansion column 212 extending into the locking hole 31.

[0078] Among them, the expansion column 212 includes a first column body 2121 at the top end and a second column body 2122 at the bottom end. The cross-sectional area of the first column body 2121 is larger than that of the second column body 2122. An inclined guide surface is provided at one end of the first column body 2121 facing away from the second column body 2122. During the process of rotating the support beam 30 towards the second upright column 20, the support beam 30 contacts the guide surface, thereby causing the expansion column 212 to contract. Until the expansion column 212 is directly opposite to the locking hole 31, under the action of the elastic member, the expansion column 212 is driven to extend into the locking hole 31. With such a setting, it is avoided that during the process of rotating the support beam 30, the expansion column 212 blocks the rotation of the support beam 30, and the process of the support beam 30 rotating to the locking position is relatively smooth.

[0079] Taking the plane perpendicular to the center line of the expansion column 212 as the cross-section, the cross-sectional shapes of the first column body 2121 and the second column body 2122 can both be circular, rectangular or polygonal, and there is no limitation thereto.

[0080] Furthermore, the stop part includes a stop tube 213, which is sleeved on the second column 2122, and the top end of the stop tube 213 is provided with a stop flange 2131 extending inward, the stop flange 2131 abuts against the first column 2121, the top end of the coil spring 211 is located in the stop tube 213 and abuts against the stop flange 2131, and a certain distance is set between the coil spring 211 and the inside of the stop tube 213 to facilitate the installation of the coil spring 211; with this arrangement, the stop tube 213 guides the telescopic column 212 and limits the coil spring 211.

[0081] Among them, a limiting flange 231 is arranged on the inner wall of the sleeve 23, and after the telescopic column 212 is extended into the locking hole 31, the stop tube 213 abuts against the limiting flange 231; in this way, when the locking device 21 locks the support beam 30, the limiting flange 231 limits the stop tube 213, thereby limiting the height of the first column 2121 extending out of the locking hole 31, and further improving the reliability of the locking device 21.

[0082] Continue to refer to Figures 6 - 9 In this embodiment, the locking device 21 also includes a bottom tube 214 and an adjusting rod 215. The center line of the bottom tube 214 is arranged in a colinear manner with the center line of the telescopic column 212, and the bottom end of the telescopic column 212 is inserted into the bottom tube 214; the bottom end of the coil spring 211 is against the top end of the bottom tube 214; the top end of the bottom tube 214 is provided with a notch 2141 extending along the center line direction of the bottom tube 214, and the notch 2141 extends in a direction perpendicular to the center line of the bottom tube 214 and penetrates the side wall of the bottom tube 214; one end of the adjusting rod 215 is connected to the telescopic column 212, and the other end of the adjusting rod 215 extends out of the notch 2141; in this way, when the support beam 30 is unlocked, the adjusting rod 215 drives the telescopic column 212 to move along the center line direction of the bottom tube 214, thereby causing the telescopic column 212 to disengage from the locking hole 31, and the support beam 30 is unlocked.

[0083] Furthermore, a fixing plate 24 is provided at one end of the bottom tube 214 away from the coil spring 211, and the fixing plate 24 is fixedly connected to the bottom tube 214. Two connecting brackets 25 are provided on the fixing plate 24, and the two connecting brackets 25 are respectively located on both sides of the bottom tube 214. Through holes are provided on the two connecting brackets 25, and mounting threaded holes are provided on the fixing plate 24 at a position opposite to the through holes. Bolts pass through the through holes and cooperate with the mounting threaded holes, and the fixing plate 24 is connected to the connecting bracket 25, and one side of the connecting bracket 25 is fixedly connected to the second column 20.

[0084] Among them, the adjustment rod 215 and the telescopic column 212 are detachably connected. For example, the connection method of the adjustment rod 215 and the telescopic column 212 can be a screw connection method, and the connection method of the adjustment rod 215 and the telescopic column 212 can also be a snap connection method, which is not limited.

[0085] Continue to refer to Figures 6 - 10 In this embodiment, a first screw 216 is provided at one end of the adjusting rod 215, and a threaded hole 21221 is provided on the side wall of the telescopic column 212. The first screw 216 cooperates with the threaded hole 21221. With such a setting, when the adjusting rod 215 is damaged, it is convenient to replace the adjusting rod 215.

[0086] Wherein, an adjusting knob 219 is provided at the end of the adjusting rod 215 away from the first screw 216. Taking the plane perpendicular to the center line of the adjusting rod 215 as the cross-section, the cross-sectional shape of the adjusting knob 219 can be circular, rectangular or polygonal, and there is no limitation thereto. The adjusting knob 219 is used for the installation and disassembly of the first screw 216.

[0087] In this embodiment, a limiting port 2142 extending along the center line direction of the bottom tube 214 is further provided at the top end of the bottom tube 214. The limiting port 2142 extends along the direction perpendicular to the center line of the bottom tube 214 and penetrates the side wall of the bottom tube 214. The limiting port 2142 is arranged opposite to the notch 2141. After the telescopic column 212 extends into the locking hole 31, the adjusting rod 215 is twisted so that the first screw 216 extends into the limiting port 2142, and the limiting port 2142 prevents the adjusting rod 215 from moving downward. With such a setting, after the telescopic column 212 extends into the locking hole 31, the support beam 30 is locked. At this time, the first screw 216 extends into the limiting port 2142 to limit the telescopic column 212, so that the support beam 30 is not easily disengaged from the lock, improving the reliability of the locking device 21.

[0088] Wherein, when the support beam 30 is unlocked, the adjusting knob 219 is twisted so that the end of the first screw 216 away from the adjusting rod 215 is placed inside the bottom tube 214, and the adjusting rod 215 drives the telescopic column 212 to move downward, so that the telescopic column 212 disengages from the locking hole 31. At this time, the support beam 30 can rotate around the rotating shaft.

[0089] Further, a second screw 217 is provided at the end of the first screw 216 away from the adjusting rod 215, and a locking nut 218 is provided on the second screw 217. A sliding hole 21222 is provided on the side wall of the telescopic column 212 close to the limiting port 2142, and the sliding hole 21222 communicates with the threaded hole 21221. The locking nut 218 slides in the sliding hole 21222. With such a setting, when the telescopic column 212 disengages from the locking hole 31, it is ensured that the first screw 216 does not disengage from the telescopic column 212, thereby improving the reliability of the locking device 21.

[0090] Wherein, one end of the first screw rod 216 departing from the adjusting rod 215 is provided with a second screw rod 217, and a locking nut 218 is arranged on the second screw rod 217. Taking the plane perpendicular to the center line of the first screw rod 216 as the cross-section, the cross-sectional area of the first screw rod 216 is larger than that of the second screw rod 217, the cross-sectional area of the threaded hole 21221 is smaller than that of the sliding hole 21222, the locking nut 218 is slidably arranged in the sliding hole 21222, and the cross-sectional area of the locking nut 218 is larger than that of the threaded hole 21221, thereby ensuring that the first screw rod 216 will not be screwed out of the telescopic column 212.

[0091] In this embodiment, the loading process of the long rail is as follows: Rotate the adjusting knob 219 on the second column 20 to screw the locking nut 218 into the sliding hole 21222. At this time, the adjusting rod 215 drives the first column body 2121 and the second column body 2122 to move downward along the direction of the notch 2141. The first column body 2121 disengages from the locking hole 31, thereby unlocking the support beam 30. At this time, the support beam 30 rotates along the rotation axis until the locking hole 31 faces the first column body 2121 on the third column 40. The spiral spring 211 pushes the stop tube 213 and the telescopic column 212 to move upward along the center line direction of the sleeve 23. When the stop tube 213 abuts against the limit flange 231, the first column body 2121 extends into the locking hole 31. At this time, the support beam 30 is locked on the third column 40, and the support beam 30 is in an open state. After loading the long rail into the installation groove, rotate the adjusting knob 219 on the third column 40 to screw the locking nut 218 into the sliding hole 21222. At this time, the adjusting rod 215 drives the first column body 2121 and the second column body 2122 to move downward along the direction of the notch 2141. The first column body 2121 disengages from the locking hole 31, thereby unlocking the support beam 30. At this time, the support beam 30 rotates along the rotation axis until the locking hole 31 faces the first column body 2121 on the second column 20. The spiral spring 211 pushes the stop tube 213 and the telescopic column 212 to move upward along the center line direction of the sleeve 23. When the stop tube 213 abuts against the limit flange 231, the first column body 2121 extends into the locking hole 31. At this time, the support beam 30 is locked on the second column 20, and the support beam 30 is in a closed state. Thus, the long rail is fixed on the rail bracket 1, and the loading of the long rail is completed; during the transportation of the long rail, the telescopic column 212 extends into the locking hole 31, thereby locking the support beam 30. Compared with locking the support beam 30 with the block, the support beam 30 is not easily disengaged from the lock, improving the reliability of locking the support beam 30.

[0092] In other embodiments, a rail transport vehicle is further provided, including a flat car body and the rail bracket 1 as described above; there are multiple rail brackets 1, and the multiple rail brackets 1 are arranged at intervals along the running direction of the flat car body; thus arranged, the rail brackets are used to carry long rails, thereby facilitating the transportation of long rails.

[0093] Among them, the structure of the rail bracket 1 is the same as that of the above-mentioned rail bracket 1, which will not be elaborated here; the center lines of the first column 10, the second column 20 and the third column 40 in the rail bracket 1 are all perpendicular to the flat car body; the support beam 30 is located between the first column 10 and the second column 20 and is arranged parallel to the flat car body; the first column 10, the second column 20 and the third column 40 are all connected to the flat car body. Exemplarily, the connection methods of the first column 10, the second column 20 and the third column 40 to the flat car body can be bolt connection or welding connection, and there is no limitation on this.

[0094] The rail transport vehicle provided in this embodiment includes the first column 10 and the second column 20 with center lines perpendicular to the horizontal plane, and the support beam 30 located between the first column 10 and the second column 20; one end of the support beam 30 is rotatably connected to the first column 10, and the rotation axis of the support beam 30 is arranged parallel to the center line of the first column 10; a locking device 21 is arranged on the second column 20, and the locking device 21 includes an elastic member and a telescopic column 212 connected to the second column 20, the center line of the telescopic column 212 is parallel to the center line of the second column 20, and the elastic member is connected to the telescopic column 212 and the second column 20; a locking hole 31 is arranged on the support beam 30, and the elastic member is used to drive the telescopic column 212 to extend into the locking hole 31 when the support beam 30 rotates until the locking hole 31 is directly opposite to the telescopic column 212; during the process of transporting long rails, the telescopic column 212 extends into the locking hole 31, thereby locking the support beam 30. Compared with locking the support beam 30 with a stop block, the support beam 30 is not easily disengaged from the lock, improving the reliability of locking the support beam 30.
