Description

Technical Field

[0001] This application relates to the field of railway track engineering technology, and in particular to a railway turnout sleeper resistance enhancement device. Background Technology

[0002] In the turnout area of ​​railway tracks, in order to ensure the normal operation of the electrical switch machine and prevent ballast (gravel on the railway track) from entering the turnout sleepers and affecting the switching of the electrical switching device, ballast blocking devices are usually installed. The main function of the ballast blocking device is to block the ballast and prevent it from entering the turnout sleepers.

[0003] In related technologies, ballast retaining devices mainly consist of a single iron plate. The friction between the plate and the track bed prevents ballast movement, thus keeping the ballast outside the turnout sleepers. However, in the structure of these retaining devices, the sides of the turnout sleepers near the signal switch machine do not contact the turnout. Furthermore, this area is a major location for wheel-rail force impacts (the collective term for all forces interacting between the wheel and the rail). Frequent wheel-rail force impacts can lead to poor condition of the ballast-supported track foundation, making it difficult for the turnout sleepers to maintain their proper position. Moreover, relying solely on the friction between the iron plate and the track bed to retain the ballast is often insufficient to cope with the frequent wheel-rail force impacts and ballast movement. In summary, the aforementioned ballast retaining devices have a low capacity to retain ballast, making it difficult to maintain the normal operation of the signal switch machine and the safety and stability of the track. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application provides a railway turnout sleeper resistance enhancement device, which can improve the ability to prevent ballast from entering the turnout sleeper, effectively maintaining the normal operation of the electrical switch machine and the safety and stability of the track.

[0005] This application provides a railway turnout sleeper resistance enhancement device, comprising:

[0006] Profile plates are detachably connected to the top surfaces of two adjacent turnout sleepers by fasteners;

[0007] A friction-enhancing structure is connected to the bottom surface of the profile plate and located between the ends of two adjacent turnout sleepers. The friction-enhancing structure is used to stop the ballast outside the ends of the two adjacent turnout sleepers. The friction coefficient of the friction-enhancing structure is greater than the friction coefficient of the profile plate.

[0008] The railway turnout sleeper resistance enhancement device according to this application has at least the following beneficial effects:

[0009] The railway turnout sleeper resistance enhancement device of this application, through the combined arrangement of profile plates and friction-enhancing structures, allows the profile plates to be detachably connected to the top surfaces of the ends of two adjacent turnout sleepers, thereby binding and fixing the two adjacent turnout sleepers together. This enables the two adjacent turnout sleepers to share the load pressure on the turnout sleepers, improving the stress stability and structural stability of the turnout sleepers. At the same time, the friction-enhancing structure stops the ballast outside the ends of the two adjacent turnout sleepers, and the friction coefficient of the friction-enhancing structure is set to be greater than that of the profile plates, increasing the frictional resistance between the friction-enhancing structure and the ballast. This increases the frictional resistance between the turnout sleeper and the track bed, and correspondingly improves the turnout sleeper's resistance to wheel-rail forces at the corresponding position, improving the positional stability of the turnout sleeper, reducing the probability of ballast entering the space between the two turnout sleepers and affecting the operation of the electrical switch machine, effectively maintaining the normal operation of the electrical switch machine and the safety and stability of the track, and improving the service life of the turnout sleepers.

[0010] In some embodiments, the friction-enhancing structure includes a stop plate connected to the profile plate and a resistance lug plate connected to the stop plate. The stop plate is positioned between the ends of two adjacent turnout sleepers, and the resistance lug plate protrudes outward toward the end of the turnout sleeper. The surface of the resistance lug plate is provided with a rough portion for contacting the ballast.

[0011] In some embodiments, the friction-enhancing structure further includes a reinforcing plate that connects the stop plate and the resistance lug plate, and the stop plate, the reinforcing plate, and the resistance lug plate form a stop groove facing outward from the end of the fork rest.

[0012] In some embodiments, there are multiple resistance lugs, all of which are spaced apart along the length of the stop plate. Each resistance lug has a rough portion on both sides along its own thickness direction, and the rough portion covers the corresponding side of the resistance lug.

[0013] In some embodiments, one end of the stop plate along its own length direction is attached to the inner side of the turnout sleeper through the rough portion of the resistance lug, and the other end of the stop plate along its own length direction is attached to the inner side of another turnout sleeper through the rough portion of another resistance lug.

[0014] In some embodiments, the stop plate, the profile plate, and the resistance lug plate are perpendicular to each other.

[0015] In some embodiments, the profile plate, the stop plate, and the resistance lug plate are integrally formed structures.

[0016] In some embodiments, the rough portion is constructed as any one of a rubber block, a plastic block, and a silicone block.

[0017] In some embodiments, a connecting sleeve is embedded at the end of the fork sleeper, and the fastener includes an integrally connected head and a rod, the rod passing through the mounting hole of the profile plate and being threadedly connected to the connecting sleeve, and the head being limited and abutting against the top surface of the profile plate.

[0018] In some embodiments, the profile plate is constructed as a steel plate structure.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In the turnout area of ​​railway tracks, in order to ensure the normal operation of the electrical switch machine and prevent ballast from entering the turnout sleepers and affecting the switching of the electrical switching device, ballast blocking devices are usually installed. The main function of the ballast blocking device is to block the ballast and prevent it from entering the turnout sleepers.

[0031] In related technologies, ballast retaining devices mainly consist of a single iron plate. The friction between the plate and the ballast bed prevents ballast movement, thus keeping the ballast outside the turnout sleepers. However, in the structure of these retaining devices, the sides of the turnout sleepers near the electrical switch machine do not contact the turnout. Furthermore, this area is the primary impact point for all forces interacting between the wheel and rail, leading to frequent wheel-rail impacts. This results in poor condition of the ballast-supported track foundation, making it difficult for the turnout sleepers to maintain their proper position. Moreover, relying solely on the friction between the iron plate and the ballast bed to retain the ballast is often insufficient to cope with the frequent wheel-rail impacts and ballast movement. In summary, the aforementioned ballast retaining devices have a low capacity to retain ballast, making it difficult to maintain the normal operation of the electrical switch machine and the safety and stability of the track.

[0032] Based on this, see Figure 1 and Figure 2 One or more embodiments of this application provide a railway turnout sleeper resistance enhancement device, which includes a profile plate 100 and a friction-increasing structure 200.

[0033] The profile plate 100 is detachably connected to the top surface of the ends of two adjacent turnout sleepers 10 by fasteners 300. The friction-enhancing structure 200 is connected to the bottom surface of the profile plate 100 and located between the ends of two adjacent turnout sleepers 10. The friction-enhancing structure 200 is used to stop the ballast outside the ends of the two adjacent turnout sleepers 10. The friction coefficient of the friction-enhancing structure 200 is greater than that of the profile plate 100.

[0034] It should be noted that in this application, turnout sleeper 10 refers to the turnout sleeper of a railway turnout, and also to the sleeper specifically used for laying and fixing turnout sections in the railway system. Its main function is to support key components of the turnout, such as the switch and frog, bear the pressure from the rails in all directions and transmit it evenly to the track bed, maintain the geometric position of the rails, and provide a fulcrum for the electrical switch machine to operate the turnout. The electrical switch machine (not shown in the figure) is an electrically driven mechanical device used to switch and lock turnouts, and to monitor the position status of the turnouts in real time to ensure accurate switching (positioning or response) of the railway line. It is one of the core equipment maintained by the electrical section (signal department).

[0035] In this application, ballast refers to the layer of crushed stone particles laid on the railway track bed (below and around the sleepers), typically composed of crushed hard, wear-resistant, and weather-resistant rock (such as granite and basalt). Its core function is to provide support, drainage, and cushioning for the track structure, and it is an important component of railway tracks. Furthermore, the track bed refers to the granular, loose structural layer laid on top of the railway subgrade and below the sleepers, typically composed of uniformly sized, high-strength, and weather-resistant crushed stone (ballast), providing elastic support and drainage for the track.

[0036] In this application, the profile plate 100 can be a metal profile plate, such as an aluminum alloy profile plate, or a composite profile plate, such as a profile plate formed by combining steel plates and iron plates. The profile plate 100 is detachably connected to the top surface of the ends of two adjacent turnout sleepers 10 by fasteners 300. The fasteners 300 can be detachable connectors such as bolts, clips, and locks, facilitating the assembly and disassembly of the profile plate 100. It should be further noted that the electrical switch machine is installed at the other end of the two adjacent turnout sleepers 10, that is, along the length of the turnout sleeper 10, the profile plate 100 and the electrical switch machine are located at opposite ends of the turnout sleeper 10.

[0037] In this application, the friction-enhancing structure 200 can be a composite structure of a rubber block and a metal plate, such as a composite structure of a rubber block and a steel plate, with the rubber block fixed to the surface of the steel plate, thereby giving the overall friction-enhancing structure 200 a large coefficient of friction. Alternatively, the friction-enhancing structure 200 can be a carbon fiber reinforced polymer matrix composite material, possessing high structural strength and a large coefficient of friction. The specific material structure of the friction-enhancing structure 200 is not limited, as long as its coefficient of friction is greater than that of the profile plate 100.

[0038] The railway turnout sleeper resistance enhancement device of this application embodiment, through the cooperation of profile plate 100 and friction-enhancing structure 200, allows the profile plate 100 to be detachably connected to the top surface of the ends of two adjacent turnout sleepers 10, thereby binding and fixing the two adjacent turnout sleepers 10 together. This allows the two adjacent turnout sleepers 10 to share the load pressure on the turnout sleeper 10, improving the stress stability and structural stability of the turnout sleeper 10. At the same time, the friction-enhancing structure 200 stops the ballast outside the ends of the two adjacent turnout sleepers 10, and the friction coefficient of the friction-enhancing structure 200 is set to be greater than that of the profile plate 10, increasing the frictional resistance between the friction-enhancing structure 200 and the ballast. This increases the frictional resistance between the turnout sleeper 10 and the track bed, and also correspondingly improves the resistance of the turnout sleeper 10 at the corresponding position to wheel-rail force, improves the positional stability of the turnout sleeper 10, reduces the probability of ballast entering the space between the two turnout sleepers 10 and affecting the operation of the electrical switch machine, effectively maintains the normal operation of the electrical switch machine and the safety and stability of the track, and improves the service life of the turnout sleeper 10.

[0039] See Figure 1 and Figure 2 In some embodiments of this application, the friction-enhancing structure 200 includes a stop plate 210 connecting the profile plate 100 and a resistance lug plate 220 connected to the stop plate 210. The stop plate 210 is positioned between the ends of two adjacent turnout sleepers 10, and the resistance lug plate 220 protrudes outward toward the end of the turnout sleeper 10. The surface of the resistance lug plate 220 is provided with a rough portion 221 for contacting the ballast.

[0040] Specifically, the profile plate 100, the stop plate 210, and the resistance ear plate 220 are integrally formed structures. The three can be welded into an integral structure, or they can be manufactured from single plate structures through processes such as bending, die casting, and stamping into an integral structure.

[0041] This simplifies the processing and assembly of the profile plate 100, the stop plate 210, and the resistance lug plate 220. It also avoids stress concentration or weak joints caused by bolt splicing, making the overall structure of the profile plate 100, the stop plate 210, and the resistance lug plate 220 more uniform, improving their structural strength and fatigue resistance, and indirectly improving the positional stability of the turnout sleeper 10 connected to the profile plate 100.

[0042] Furthermore, the stop plate 210, the profile plate 100, and the resistance ear plate 220 are perpendicular to each other. The profile plate 100 is vertically connected to the top surface of the corresponding ends of two adjacent turnout sleepers 10. The stop plate 210 is vertically inserted between the corresponding ends of two adjacent turnout sleepers 10, and the stop plate 210 is perpendicular to the profile plate 100. The resistance ear plate 220 is also located between the corresponding ends of two adjacent turnout sleepers 10, and the resistance ear plate 220 is perpendicular to the surface of the stop plate 210 near the outer end of the turnout sleeper 10. The resistance ear plate 220 is perpendicular to the bottom surface of the profile plate 100.

[0043] By making the stop plate 210, the profile plate 100, and the resistance lug plate 220 perpendicular to each other, on the one hand, the friction-enhancing structure 200 is connected to the profile plate 100 as a whole, and on the other hand, the stop plate 210 and the resistance lug plate 220 of the friction-enhancing structure 200 are connected intersectingly rather than stacked, thereby increasing the contact area between the friction-enhancing structure 200 and the ballast, thereby increasing the friction between the friction-enhancing structure 200 and the ballast, and further improving the positional stability of the turnout sleeper 10.

[0044] It is understandable that the stop plate 210 is positioned between the ends of two adjacent turnout sleepers 10. Its two ends along its length are constrained by the corresponding sides of the two turnout sleepers 10 to maintain a stable position. At the same time, the stop plate 210 itself forms a stop surface to stop the ballast, preventing the ballast from entering the space between the two adjacent turnout sleepers 10. The resistance lug 220 protrudes outward toward the end of the turnout sleeper 10. Through the rough part 221 with a large coefficient of friction, the friction between the resistance lug 220 and the ballast is increased. This increases the frictional resistance between the turnout sleeper 10 as a whole and the track bed, reduces the probability of the turnout sleeper 10 shifting laterally (lateral movement refers to the direction perpendicular to the turnout sleeper), and further improves the positional stability of the turnout sleeper 10.

[0045] Specifically, the rough portion 221 is constructed as any one of a rubber block, a plastic block, and a silicone block. In one embodiment, the rough portion 221 is a rubber block adhered to the surface of the resistance lug 220 along its thickness direction. The resistance lug 220, the stop plate 210, and the profile plate 100 are all steel plates, ensuring that the resistance lug 220, the stop plate 210, and the profile plate 100 have high structural strength. At the same time, by utilizing the larger coefficient of friction of the rubber block, the overall coefficient of friction of the friction-enhancing structure 200 is increased, making the coefficient of friction of the friction-enhancing structure 200 greater than that of the profile plate 100. Furthermore, through the contact between the rubber block on the resistance lug 220 and the ballast, the frictional force between the friction-enhancing structure 200 and the ballast is increased, thereby improving the positional stability of the turnout sleeper 10.

[0046] Further, see Figure 1 and Figure 2The friction-enhancing structure 200 also includes a reinforcing plate 230, which connects the stop plate 210 and the resistance lug plate 220. The stop plate 210, the reinforcing plate 230 and the resistance lug plate 220 form a stop groove 240 facing the end of the fork bolster 10.

[0047] Specifically, the reinforcing plate 230, the stop plate 210, and the resistance ear plate 220 are integrally formed structures, and the three can be integrally formed by die casting. Of course, the profile plate 100, the stop plate 210, the resistance ear plate 220, and the reinforcing plate 230 are integrally formed structures, and the four can be integrally manufactured by die casting.

[0048] See Figure 2 To further increase the friction between the friction-enhancing structure 200 and the ballast, the reinforcing plate 230 is parallel to and spaced apart from the profile plate 100. The reinforcing plate 230 is connected to the profile plate 100 through the resistance lug plate 220 and the stop plate 210. The reinforcing plate 230 forms the base plate of the friction-enhancing structure 200. The resistance lug plate 220 and the stop plate 210 are respectively vertically connected to the reinforcing plate 230. The stop plate 210, the reinforcing plate 230, the resistance lug plate 220 and the profile plate 100 together define the stop groove 240, which is a U-shaped groove with its opening facing outwards from the end of the turnout sleeper 10.

[0049] This design not only increases the overall wall area of ​​the friction-enhancing structure 200, thereby increasing the contact area between the friction-enhancing structure 200 and the ballast, thus increasing the friction between the friction-enhancing structure 200 and the ballast and improving the positional stability of the turnout sleeper 10, but also allows the stop groove 240 to more effectively accommodate and stop the ballast outside the end of the turnout sleeper 10, further reducing the probability of ballast entering the turnout sleeper 10 and affecting the operation of the electrical switch machine, effectively maintaining the normal operation of the electrical switch machine and the safety and stability of the track, and improving the service life of the turnout sleeper 10.

[0050] See also some embodiments of this application. Figure 1 and Figure 2 The resistance lugs 220 are multiple, and all the resistance lugs 220 are distributed at intervals along the length direction of the stop plate 210. The resistance lugs 220 are provided with rough portions 221 on both sides along their own thickness direction, and the rough portions 221 cover the corresponding sides of the resistance lugs 220.

[0051] See also Figure 2 The resistance ear plate 220 has three plates, which are parallel to and spaced apart along the length of the stop plate 210. They together with the stop plate 210 and the profile plate 100 form two stop grooves 240. The inner and outer walls of each stop groove 240 are covered with rough parts 221.

[0052] Thus, increasing the distribution density of the resistance lugs 220 corresponds to increasing the coverage area of ​​the rough portion 221, thereby increasing the contact area between the friction-enhancing structure 200 and the ballast, and correspondingly increasing the friction between the friction-enhancing structure 200 and the ballast, thereby improving the positional stability of the turnout sleeper 10.

[0053] Further, see Figure 1 and Figure 2 One end of the stop plate 210 along its own length direction is attached to the inner side of the turnout 10 through the rough part 221 of the resistance lug 220, and the other end of the stop plate 210 along its own length direction is attached to the inner side of another turnout 10 through the rough part 221 of another resistance lug 220.

[0054] Specifically, the rough portion 221 is constructed as an elastic rubber block or silicone block.

[0055] Understandably, along the length of the stop plate 210, the rough portions 221 of the two opposite resistance lugs 220 at the farthest point are tightly fitted to the corresponding inner surfaces of the turnout sleeper 10 under the limiting constraint of the corresponding ends of the stop plate 210. In this way, on the one hand, the overall installation stability of the stop plate 210 and the friction-enhancing structure 200 is improved, and on the other hand, the contact gap between the friction-enhancing structure 200 and the turnout sleeper 10 can be reduced or even eliminated by the fitting effect of the rough portions 221 and the inner surfaces of the turnout sleeper 10, further reducing the probability of ballast entering the turnout sleeper 10, thereby improving the positional stability of the turnout sleeper 10 and maintaining the normal operation of the electrical switch machine and the safety and stability of the track.

[0056] Further, see Figure 1 and Figure 2 The end of the fork bolster 10 is provided with a connecting sleeve (not shown in the figure). The fastener 300 includes an integrally connected head 310 and a rod 320. The rod 320 passes through the mounting hole 110 of the profile plate 100 and is threadedly connected to the connecting sleeve. The head 310 is limited and abuts against the top surface of the profile plate 100.

[0057] Specifically, the turnout sleeper 10 is a sleeper structure formed by pouring concrete and reinforcing steel. The connecting sleeve is pre-embedded in the concrete when the turnout sleeper 10 is poured, forming a sleeve structure formed by pouring concrete and reinforcing steel. The connecting sleeve can be understood as a blind hole channel with internal threads inside the turnout sleeper 10. The fastener 300 can be a bolt, with the head 310 of the fastener 300 corresponding to a nut and the rod 320 corresponding to a stud. When connecting and assembling the profile plate 100, the profile plate 100 is first attached to the top surface of the corresponding ends of the two turnout sleepers 10, and then the rod 320 of the fastener 300 is passed through the mounting hole 110 of the profile plate 100 and screwed into the connecting sleeve. When the head 310 of the fastener 300 first abuts against the top surface of the profile plate 100, the process of detachably fixing the profile plate 100 to the turnout sleeper 10 is completed.

[0058] Furthermore, it should be noted that there are multiple fasteners 300 and multiple mounting holes 110 on the profile plate 100. One end of the profile plate 100 is detachably connected to the top surface of the corresponding end of the turnout sleeper 10 by at least two fasteners 300, and the other end of the profile plate 100 is also detachably connected to the top surface of the end of another turnout sleeper 10 by at least two fasteners 300. In this way, the installation stability of the profile plate 100 is improved, and the two turnout sleepers 10 are subjected to more even force, further improving the positional stability of the turnout sleepers 10.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
