[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0061] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0062] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0063] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or service tool that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or service tool.

[0064] The long rail transport train is used to load and transport long rails. In order to prevent the rails from accidentally jumping out and impacting other structures of the long rail transport train during transportation, a rail safety door stop device is provided at the end of the rail on the long rail transport train.

[0065] The existing rail safety door stop device comprises two door post assemblies, two door panel assemblies and four hinges, wherein the door panel assemblies are welded by section steel and steel plates, and the door panel assemblies are rotatably connected to the door post assemblies through hinges.

[0066] The door panel assembly can rotate relative to the door post assembly to open and close the safety door stop device of the rail. When the safety door stop device of the rail is closed, it can prevent the rails on the long rail transport vehicle set from accidentally jumping out and impacting other structures of the long rail transport vehicle set. Specifically, when the rail jumps out, it stops jumping after hitting the safety door stop device of the rail in a closed state. Since the existing door panel assembly is welded by steel sections and steel plates and has no energy buffer device, when the rail hits the safety door stop device of the rail, the safety door stop device of the rail will bear a large impact force, thereby damaging the safety door stop device of the rail.

[0067] The long rail transport train is equipped with a winch, which is used to load the rails. The winch is located on the other side of the rail safety gate stop device, that is, the rail safety gate stop device is located between the rail and the winch. The winch is equipped with a wire rope. When the rail safety gate stop device is opened, the wire rope on the winch passes through the rail safety gate stop device to load the rail. The existing rail safety gate stop device is not provided with a device for adjusting the position of the wire rope, and the wire rope is not restricted when passing through the rail safety gate stop device. Therefore, when loading the rail, the wire rope will scrape the rail safety gate stop device and the position of the wire rope is not conducive to the loading of the rail.

[0068] Based on this, the present invention provides a safety door stop device for rails, which includes a limit assembly, two door post assemblies and two door panel assemblies. When loading rails, the limit assembly limits the position of the wire rope so that the wire rope will not scrape the safety door stop device for the rails, and the position of the wire rope can be constrained according to actual operation requirements, which is beneficial to rail loading.

[0069] Figure 1 A schematic structural diagram of a rail safety door stop device provided in an embodiment of the present invention; Figure 2 for Figure 1 Side view of Figure 3 for Figure 1 Top view of the .

[0071] The limiting assembly 10 includes a support frame 11 and a limiting unit 12 arranged on the support frame. The support frame 11 is connected to the upper part of the door column assembly 20. The limiting unit 12 is used to support the wire rope of the winch and limit the moving position of the wire rope.

[0072] As mentioned above, the long rail transport train is used to load and transport long rails, and a rail safety door stopper is provided on the long rail transport train to prevent the rails on the long rail transport train from accidentally jumping out and impacting other structures of the long rail transport train. A winch is provided on the long rail transport train to load the rails, and the rail safety door stopper is located between the rails and the winch on the long rail transport train.

In this embodiment, the door column assembly 20 is welded by H-shaped steel 21 and plate 22. In other embodiments, the door column assembly 20 can also be composed of other steel sections and plates. The door panel assembly 30 is connected to the carriage of the long rail transport train set through the door column assembly 20.

[0075] Figure 8A schematic diagram of the structure of a folding assembly in a rail safety door stop device provided by an embodiment of the present invention; Fig. 9 for Figure 8 A top view of Fig.10 for Figure 4 A partial enlarged view of point A in the middle.

[0076] In a specific implementation, the rail safety door stop device also includes a hinge assembly 40, see Figure 8 and Fig. 9 As shown, the folding assembly 40 includes a first folding body 41, a second folding body 42 and a first shaft pin 43. The first folding body 41 and the second folding body 42 are connected together by the first shaft pin 43 and rotate around the first shaft pin 43. Figures 1 to 3 As shown, the first hinge body 41 and the second hinge body 42 are respectively connected to the door column assembly 20 and the door panel assembly 30, so that the door panel assembly 30 can rotate relative to the door column assembly 20 to be in an open state or a closed state. Figure 4 and Fig.10 As shown, a roller assembly 36 is further provided below the door panel assembly 30, and the roller assembly 36 includes a roller seat plate 361, a roller 362 and a second shaft pin 363, and the roller 362 is mounted on the roller seat plate 361 through the second shaft pin 363. When the door panel assembly 30 rotates relative to the door column assembly 20, the roller 362 rolls on the surface of the long rail transport vehicle group to support the door panel assembly 30 and reduce the friction when the door panel assembly 30 rotates.

[0077] When loading the rails, the door panel assembly 30 rotates relative to the door post assembly 20 to open the safety door stopper of the rails, and the wire rope passes through the safety door stopper of the rails to load the rails. The limiting assembly 10 is used to limit the position of the wire rope when loading the rails.

[0078] Fig.11 A schematic structural diagram of a limiter component in a rail safety door stop device provided by an embodiment of the present invention; Fig.12 for Fig.11 A top view of Fig.13 for Fig.11 Side view of.

[0079] See also Figure 1 , Figure 3 , Figures 11 to 13As shown, the limiting assembly 10 is provided with a support frame 11 for connecting the limiting unit 12 to the door column assembly 20 and limiting the limiting unit 12 to the upper part of the door column assembly 20. In this embodiment, the support frame 11 includes two horizontal arms 111 and two inclined arms 112, the horizontal arms 111 and the inclined arms 112 correspond to each other, and the corresponding horizontal arms 111 and the inclined arms 112 form a tripod structure. The open end of the tripod structure faces the door column assembly 20 and the horizontal arms 111 and the inclined arms 112 are both connected to the door column assembly 20, thereby, the support frame 11 can firmly connect the limiting assembly 10 to the upper part of the door column assembly 20.

[0080] The limiting unit 12 provided on the support frame 11 is used to support the wire rope of the hoist when loading the rails and to limit the position of the wire rope. Figure 1 and Fig.11 As shown, the direction parallel to the horizontal arm 111 is called the horizontal direction X, and the direction perpendicular to the horizontal arm 111 is called the vertical direction Y. The support frame 11 fixes the limiting unit 12 on the upper part of the door column assembly 20 along the vertical direction Y and limits the limiting unit 12 between the door column assembly 20 along the horizontal direction X. The steel wire rope passes through the limiting unit 12 before loading the rail. Therefore, when the steel wire rope passes through the limiting unit 12 to load the rail, the steel wire rope will not scratch the safety door stop device of the rail, and the steel wire rope has a sufficient height adjustment range, and the position of the steel wire rope can be constrained according to the actual operation requirements, which is conducive to loading the rail.

[0081] Please continue to see Fig.11 and Fig.13 As shown, the limiting unit 12 includes a supporting assembly 121 and two baffles 122 . The supporting assembly 121 is connected to the supporting frame 11 . The supporting assembly 121 is used to support the steel wire rope. The two baffles 122 are respectively arranged on both sides of the axis of the supporting assembly 121 to limit the steel wire rope between the baffles 122 .

[0082] When loading the rails, the support assembly 121 is the main force-bearing part. The support assembly 121 supports the steel wire rope along the vertical direction Y, and the steel wire rope passes through the support assembly 121 to load the rails. The baffles 122 arranged on both sides of the axis of the support assembly 121 are used to limit the steel wire rope between the baffles 122 along the horizontal direction X. The steel wire rope can only move on the support assembly 121 between the two baffles 122 in the horizontal direction X, and the steel wire rope will not approach the two sides of the safety door stop device of the rail, thereby not scratching the safety door stop device of the rail.

[0083] Fig.14 A schematic diagram of the structure of a support assembly in a rail safety door stop device provided by an embodiment of the present invention; Fig.15 for Fig.13 A partial enlarged view of point B in the middle. Fig.11 , Figures 13 to 15 As shown, the supporting assembly 121 includes a roller 1211 and a supporting shaft 1212 . The roller 1211 is sleeved on the supporting shaft 1212 , and the roller 1211 can rotate relative to the supporting shaft 1212 .

[0084] When loading the rails, the roller 1211 can rotate relative to the support shaft 1212 to reduce the friction between the wire rope and the roller 1211. Therefore, the load on the support assembly 121 can be reduced so that the winch can load the rails with less force and reduce the wear of the support assembly 121 and the wire rope.

[0085] The limiting unit 12 further includes two connecting components 123 . The connecting components 123 are arranged in one-to-one correspondence with the baffles 122 . The baffles 122 are connected to the support shaft 1212 via the connecting components 123 .

[0086] The two baffles 122 are fixedly connected to the two sides of the support shaft 1212 through the connecting components 123 respectively. When the drum 1211 rotates relative to the support shaft 1212, the baffles 122 remain stationary to limit the wire rope on the drum 1211 in the horizontal direction X.

[0087] Please continue to see Fig.14 As shown, the support shaft 1212 includes a support shaft body 1213 and two mounting portions 1214. The two mounting portions 1214 are respectively located at two ends of the support shaft body 1213 and are coaxially arranged with the support shaft body 1213.

[0088] The support assembly 121 further includes at least two bearings 1216, at least two bearing glands 1217 and at least two elastic retaining rings 1218. At least one bearing 1216 and one bearing gland 1217 are sleeved on the mounting portion 1214. The outer wall of the bearing 1216 and the outer wall of the bearing gland 1217 are both in contact with the inner wall of the drum 1211. The elastic retaining ring 1218 is arranged on the inner wall of the drum 1211. The bearing gland 1217 is located between the bearing 1216 and the elastic retaining ring 1218.

[0089] The inner side wall of the drum 1211 has an installation step 1211a, the elastic retaining ring 1218 abuts against the bearing cover 1217, and the side wall of the outer ring of the bearing 1216 abuts against the installation step 1211a to restrict the bearing 1216 and the bearing cover 1217 between the installation step 1211a and the elastic retaining ring 1218.

[0090] Specifically, the support shaft body 1213 is the main bearing part of the support shaft 1212, and the mounting portion 1214 is used to connect the support shaft 1212 to the drum 1211. The mounting portion 1214 includes a first mounting section 1214a, and a step portion 1215 is provided between the first mounting section 1214a and the support shaft body 1213, and the step portion 1215 and the mounting step 1211a together form a mounting plane. The side wall of the inner ring of the bearing 1216 abuts against the step portion 1215, and the side wall of the outer ring of the bearing 1216 abuts against the mounting step 1211a. The bearing 1216, the bearing cover 1217 and the elastic retaining ring 1218 are sequentially arranged on the first mounting section 1214a starting from the mounting plane. The bearing 1216 is used to support the rotation of the drum 1211 relative to the support shaft 1212. The bearing cover 1217 is connected to the drum 1211 and rotates with the rotation of the drum 1211. The bearing cover 1217 is used to press the outer ring of the bearing 1216. A felt ring 1219 is also provided on the inner wall of the bearing cover 1217 for dust prevention. The elastic retaining ring 1218 is clamped on the inner wall of the drum 1211 to limit the bearing cover 1217 and the bearing 1216 in the axial direction.

[0091] The rotational connection between the drum 1211 and the support shaft 1212 via the bearing 1216 can reduce the friction between the drum 1211 and the support shaft 1212 and ensure the rotation accuracy of the drum 1211, which is beneficial for adjusting the position of the wire rope.

[0092] Please continue to see Fig.15 As shown, the connection assembly 123 includes a support seat 1231, a pressing plate 1232 and at least one first connecting member 1233. The support seat 1231 is fixedly connected to the support frame 11. The support seat 1231 has a receiving groove 1231a for receiving the mounting portion 1214. The mounting portion 1214 is inserted into the receiving groove 1231a. The pressing plate 1232 is covered on the mounting portion 1214. The pressing plate 1232 is connected to the support seat 1231 through the first connecting member 1233.

[0093] The baffle plate 122 is disposed on the pressing plate 1232 , and the baffle plate 122 is located above the mounting portion 1214 .

[0094] In a specific implementation, the support seat 1231 can be welded to the horizontal arm portion 111 of the support frame 11, and a receiving groove 1231a is provided on the support seat 1231, and the receiving groove 1231a is a U-shaped groove, and the opening of the U-shaped groove is upward. The mounting portion 1214 also includes a second mounting section 1214b, and the diameter of the second mounting section 1214b can be smaller than that of the first mounting section 1214a. Cuts are made on both sides of the second mounting section 1214b so that the shape of the second mounting section 1214b matches the U-shaped groove, and the support shaft 1212 is inserted into the receiving groove 1231a through the second mounting section 1214b.

[0095] After the second mounting section 1214 b is inserted into the receiving groove 1231 a , the pressing plate 1232 is covered on the supporting seat 1231 to restrict the supporting shaft 1212 in the vertical direction Y. In this embodiment, the pressing plate 1232 is connected to the supporting seat 1231 via a first connecting member 1233 .

[0096] The baffle 122 can be formed integrally with the pressure plate 1232 , and the baffle 122 extends upward in the vertical direction Y above the second mounting section 1214 b , so that the baffle 122 located on both sides of the support shaft 1212 can limit the position of the wire rope along the axial direction of the support shaft 1212 .

[0097] Please continue to see Figures 1 to 3 As shown, the safety door stop device for rails further includes a buffer assembly 50, which is arranged on a side of the door panel assembly 30 facing the rails.

[0098] After the rails are loaded, the door panel assembly 30 is rotated to close the safety door stop device of the rails. When the rails are ejected due to external force and impact the safety door stop device of the rails, the buffer assembly 50 arranged on the side of the door panel assembly 30 facing the rails can absorb the energy of the impact of the rails to reduce the impact force of the rails, thereby protecting the door panel assembly 30.

Fig.16 As shown, for ease of assembly, the buffer assembly 50 includes a plurality of buffer pads 51 , which are sequentially connected to a side of the door panel assembly 30 facing the rail through a second connecting member 52 , and the sides of two adjacent buffer pads 51 abut against each other to completely cover the door panel assembly 30 .

[0100] In this embodiment, the buffer pad 51 is a wooden buffer pad or a rubber buffer pad, the second connecting member 52 is a countersunk bolt, and the buffer pad 51 has a countersunk hole matching the countersunk bolt.

[0101] Wooden buffer pads and rubber buffer pads are preferred as buffer pads 51 due to their low cost, easy processing and good energy absorption effect. In this embodiment, the second connecting member 52 uses a countersunk bolt, so that the safety door stop device of the rail is a buffer pad on the side facing the rail, without protruding hard materials. When the rail impacts the safety door stop device of the rail, there is no hard contact, and the impact energy can be absorbed by the buffer pad to achieve a good buffering effect.

[0102] Please continue to see Figures 1 to 3As shown, the safety door stop device for the rail further includes a stopper assembly 60, which includes a rotating stopper 61 and a fixed stopper 62, and the fixed stopper 62 is adjacent to a side of the door panel assembly 30 away from the rail to limit the door panel assembly 30 from rotating away from the rail;

[0103] The rotating stopper 61 is adjacent to the side of the door panel assembly 30 facing the rail, and the rotating stopper 61 can rotate and switch between a vertical state and a horizontal state. When the rotating stopper 61 is in a horizontal state, the door panel assembly 30 can rotate toward one side of the rail. When the rotating stopper 61 is in a vertical state, the door panel assembly 30 is located between the rotating stopper and the fixed stopper.

The fixed baffle 621 is installed on the body of the long rail transport vehicle group and is located on the side of the door panel assembly 30 away from the rail to limit the door panel assembly 30 from rotating away from the rail. The supporting rib 622 is used to support the fixed baffle 621, so that the fixed baffle 62 can bear a larger load. When the energy of the safety door stop device of the rail impacting the rail is large, the door panel assembly 30 can also be limited from rotating away from the rail, thereby preventing the rail from accidentally jumping out and impacting the rest of the vehicle structure.

[0105] In this embodiment, the rotating block 61 is arranged in a one-to-one correspondence with the door panel assembly 30, so as to make one of the door panel assemblies 30 in an open state or a closed state, or make two door panel assemblies 30 in an open state or a closed state according to actual operation requirements.
