Description

Technical Field

[0001] This utility model relates to the field of railway technology, specifically to a reinforcement structure for enhancing the load-bearing capacity of railway dedicated lines. Background Technology

[0002] Dedicated railway lines, as crucial transportation channels connecting main railway lines with dedicated areas such as enterprises, ports, and stations, undertake important tasks such as the distribution of bulk cargo and the transport of special materials. Their track load-bearing capacity directly affects transportation efficiency and train safety. With the rapid development of the logistics industry, freight volume on dedicated railway lines has continued to climb, and the frequency of heavy-haul trains has increased significantly. At the same time, some dedicated lines have been in service for a long time, and the track foundations are prone to settlement and cracking after long-term vibration and environmental erosion, leading to a decrease in track load-bearing capacity and making it difficult to meet current heavy-haul transportation demands.

[0003] In track reinforcement projects, traditional reinforcement structures often employ fixed designs, which can only adapt to specific track gauges and locations. They are poorly adaptable to complex areas with varying track gauges and limited space, such as station throats and near turnouts, making precise reinforcement difficult. Furthermore, traditional reinforcement structures lack adjustment flexibility, requiring numerous customized components and complex construction equipment during construction. This not only prolongs the construction period but also increases costs. Especially when performing reinforcement work on existing lines without interrupting operations, it can easily disrupt normal transportation. Utility Model Content

[0021] This embodiment provides a reinforcement structure for enhancing the load-bearing capacity of railway dedicated lines, such as... Figures 1-5 As shown, it includes: a base plate 1, with a reinforcing plate 2 fixedly installed on top of the base plate 1. The base plate 1 is made of Q235B hot-rolled steel plate with a thickness of not less than 12mm to ensure the bottom support rigidity; the reinforcing plate 2 is made of 5mm thick steel plate of the same material, arranged at intervals of 400mm along the length of the base plate 1, and the height of the reinforcing plate 2 is flush with the guide plate 41, which can evenly distribute the vertical load transmitted by the track to the entire area of ​​the base plate 1, avoiding local stress concentration that could lead to deformation of the base plate; the top of the base plate 1 and located at the reinforcing plate 2 A mounting hole 3 is provided on one side, with a hole diameter of 20mm and a center distance of 50mm from the edge of the base plate 1. A set of two symmetrically distributed holes is provided every 600mm along the length of the base plate 1. During installation, it is anchored to the ground foundation with M18 expansion bolts. The pull-out force of a single set of bolts is not less than 80kN to ensure a stable connection between the base plate 1 and the ground and to prevent the reinforced structure from shifting under heavy load. A guide mechanism 4 is provided in the middle of the top of the base plate 1, and a sliding mechanism 5 is provided on the top of the guide mechanism 4. The guiding mechanism 4 includes a guide plate 41, a guide groove 42, and an anti-detachment groove 43. The guide plate 41 is fixedly installed at the center of the top of the base plate 1. The guide plate 41 is made of 10mm thick Q235B steel plate, with a height of 80mm and a length that matches the base plate 1. The guide groove 42 on its top is 50mm wide and 40mm deep. The anti-detachment groove 43 is opened on the inner side wall of the guide groove 42, with a groove width of 15mm and a groove depth of 10mm. The anti-detachment groove 43 can completely eliminate the risk of the sliding block 51 detaching from the guide plate 41 when sliding laterally by engaging with the protrusion 52. The guide groove 42 is opened on the top of the guide plate 41, and the anti-detachment grooves 43 are opened on both sides inside the guide groove 42 on the top of the guide plate 41. The sliding mechanism 5 includes a sliding block 51, a protrusion 52, and a sliding plate 53. The sliding block 51 is slidably mounted on the inner wall of the guide plate 41 through the opening of the guide groove 42. The sliding block 51 is made of No. 45 steel and has been heat-treated (hardness HRC28-32). Its cross-sectional dimensions match the guide groove 42 (width 49.8mm, height 39.8mm), and the fitting clearance is controlled within 0.2mm to ensure smooth sliding and prevent lateral wobbling. The protrusion 52 is integrally formed with the sliding block 51, and its dimensions are adapted to the anti-disengagement groove 43 (width 14.8mm, height 9.8mm). The surface of the protrusion 52 is coated with polytetrafluoroethylene for wear resistance. The coating has a friction coefficient ≤0.15, which can reduce sliding wear and extend service life. The two sides of the sliding block 51 are fixedly installed with the protrusion 52. The protrusion 52 is located in the anti-detachment groove 43 and is slidably connected with the guide plate 41. The top of the sliding block 51 is fixedly installed with the sliding plate 53. The sliding plate 53 is made of 8mm thick Q235B steel plate with an area of ​​not less than 300mm×200mm (length×width). Its bottom is fully welded to the sliding block 51 (weld leg height 6mm). The welding strength must meet the tensile strength ≥400MPa to ensure that the sliding plate 53 can stably bear the load of the telescopic mechanism 6 and the reinforcing mechanism 7 above. A telescopic mechanism 6 is provided on the top of the sliding plate 53, and a reinforcing mechanism 7 is provided on the side of the telescopic mechanism 6 away from the sliding mechanism 5. The telescopic mechanism 6 includes an L-shaped plate 61, a movable insert plate 62, and a guide rod 63. The L-shaped plate 61 is fixedly installed on the top of the sliding plate 53. The L-shaped plate 61 is formed by bending 8mm thick Q235B steel plate, and the lengths of the right-angled sides are 200mm (vertical side) and 300mm (horizontal side). The horizontal side is connected to the sliding plate 53 by 4 sets of M12 bolts (bolt spacing 100mm). The bolt tightening torque is controlled at 50-60N·m to ensure a rigid connection between the L-shaped plate 61 and the sliding plate 53. The inner wall of the L-shaped plate 61 away from the sliding plate 53 is movably inserted into the movable insert plate 62. Plate 62 is made of 6mm thick Q235B steel plate, with a width of 180mm and a length of 400mm. Its insertion depth into L-shaped plate 61 is adjustable from 100-300mm to accommodate the reinforcement needs of different track gauges (such as 1435mm standard rail and 1520mm wide rail). Guide rod 63 is movably inserted into the inner wall of L-shaped plate 61 and located on both sides of movable insert plate 62. Guide rod 63 is a Φ16mm No. 45 steel optical shaft with chrome plating (plating thickness ≥0.02mm). Its length is adapted to movable insert plate 62, and its fit clearance with L-shaped plate 61 is 0.1-0.2mm. It can accurately guide the extension and retraction direction of movable insert plate 62 and prevent movable insert plate 62 from deflecting during extension and retraction. The reinforcement mechanism 7 includes a fixing block 71, triangular reinforcing ribs 72, a reinforcing plate 73, and connecting bolts 74. The fixing block 71 is fixedly installed on the side of the movable insert plate 62 and guide rod 63 away from the L-shaped plate 61. The fixing block 71 is a cubic structure (made of 45# steel, with dimensions of 80mm×80mm×80mm). It is fully welded to the movable insert plate 62 and guide rod 63, with a weld leg height of not less than 8mm to ensure the continuity of load transfer. The top and both sides of the bottom plate of the fixing block 71 are fixedly installed with triangular reinforcing ribs 72. The triangular reinforcing ribs 72 are made of 5mm thick Q235B steel plate, with a right angle side length of 80mm. Each fixing block 71 is equipped with 4 sets (1 set each on the top, bottom, left, and right). The welding surfaces of the reinforcing ribs to the fixing block 71 and the bottom plate 1 need to be derusted and inspected after welding to avoid false welding. This can improve the bending resistance of the fixing block 71 by more than 60%. The reinforcing rib 72 is fixedly installed on the side away from the movable insert plate 62 with the reinforcing plate 73. The reinforcing plate 73 is made of 10mm thick high manganese steel plate (Mn13), which has high wear resistance. The plate body has an arc-shaped notch that matches the groove at the bottom of the rail (the arc is consistent with the bottom radius of the rail). A 3mm thick neoprene rubber buffer pad (Shore hardness 65HA) is pasted at the arc-shaped notch, which can reduce the hard contact wear between the reinforcing plate 73 and the rail, and absorb vibration impact. Several sets of connecting bolts 74 are provided. Several sets of connecting bolts 74 are connected to the inner wall of the reinforcing plate 73 with transverse threads. The connecting bolts 74 are 8.8 grade high strength bolts (specification M16×50). A set is set every 50mm along the height direction of the reinforcing plate 73, with 2 bolts symmetrically distributed in each set. The tightening torque is controlled at 80-100N・m. Spring washers are added to the bolt heads to prevent the bolts from loosening due to long-term vibration and to ensure a tight fit between the reinforcing plate 73 and the rail. The top of the telescopic mechanism 6 is equipped with an adjustment mechanism 8, which includes a shaft bracket 81, a screw 82, and an adjusting nut 83. The shaft bracket 81 is fixedly installed on the top of the L-shaped plate 61. The shaft bracket 81 is welded from an 8mm thick Q235B steel plate. Two sets of shaft brackets 81 are symmetrically distributed on the top of the L-shaped plate 61, with the spacing adapted to the length of the screw 82. A Φ22mm round hole is opened on the top of the shaft bracket 81, and a copper sleeve (material ZCuSn10Pb1) is installed inside. The clearance between the copper sleeve and the screw 82 is 0.15mm, which can reduce the wear of the screw 82 when it rotates. The inner wall of the shaft bracket 81 is rotatably installed with the screw 82, which is Φ20mm. The trapezoidal thread (4mm pitch) is made of 45# steel and heat-treated, with a thread accuracy of 7H. Its thread engagement with the movable plate 92 has self-locking properties (self-locking angle ≤3°), ensuring that the movable insert plate 62 will not automatically retract after being extended or retracted to its position. The side of the shaft bracket 81 away from the fixed block 71 is rotatably installed with the adjusting nut 83. The adjusting nut 83 is fixedly connected to the screw rod 82. The adjusting nut 83 adopts a hexagonal nut structure (width across sides 30mm), is made of 45# steel, and has a galvanized surface for rust prevention. An extended handle (150mm in length) is welded to the outside of the nut, which can reduce the adjustment force through the lever principle, allowing a single person to complete the operation and improving construction efficiency. The inner wall of the telescopic mechanism 6 is provided with a linkage component 9, which includes a through groove 91 and a movable plate 92. The through groove 91 is opened on the top of the L-shaped plate 61. The through groove 91 is 30mm wide and 300mm long, and the edge of the groove is rounded (rounded corner radius 5mm) to prevent the movable plate 92 from being scratched by the sharp edge when sliding. The movable plate 92 is fixedly installed on the top of the movable insert plate 62 away from the fixed block 71. The movable plate 92 is made of 10mm thick Q235B steel plate and has a size of 40mm×100mm (width×length). A trapezoidal threaded hole adapted to the screw 82 is opened in its center. The perpendicularity error between the threaded hole and the movable plate 92 is ≤0.1mm / m to ensure that the movable plate 92 can move linearly along the axis of the screw 82. The movable plate 92 is located in the through groove 91 and is slidably connected to the L-shaped plate 61. The movable plate 92 is threadedly connected to the surface of the screw 82. A protective cover 100 is threadedly connected to the top of the L-shaped plate 61 and to the inner wall of the shaft bracket 81. The protective cover 100 is made of ABS engineering plastic with a thickness of 3mm. It is fixed to the L-shaped plate 61 by 4 sets of M5 self-tapping screws. The cover completely covers the through groove 91, the screw 82 and the top of the shaft bracket 81, which can effectively prevent rainwater, gravel and dust from entering the interior, avoid thread corrosion or jamming, and ensure the long-term stable operation of the adjustment mechanism 8.

[0022] In summary, the reinforcement structure for enhancing the load-bearing capacity of railway dedicated line tracks provided in this embodiment has the following advantages: the combined use of guide plate 41, guide groove 42, and anti-detachment groove 43 can provide stable guidance for sliding mechanism 5, while also preventing sliding mechanism 5 from detaching from the connection with guide plate 41, ensuring high stability during adjustment; the combined use of sliding block 51, protrusion 52, and sliding plate 53 allows users to easily adjust the position of L-shaped plate 61, thereby enabling the L-shaped plate 61 to be moved to the track section requiring reinforcement in a short time, and also allowing for fine-tuning to increase accuracy; the combined use of L-shaped plate 61, movable insert plate 62, and guide rod 63 can provide stable support for reinforcement mechanism 7, and allow it to extend and retract to ensure precise docking with railway track; the combined use of fixing block 71, triangular reinforcing rib 72, reinforcement plate 73, and connecting bolt 74 enables connection with the track, and provides stable support to the track with the support force of L-shaped plate 61, thereby enhancing its load-bearing capacity; The combined use of the axle bracket 81, screw 82, and adjusting nut 83 allows the user to rotate the movable plate 92 to move, enabling it to extend and retract the movable insert plate 62. The screw 82 and movable plate 92 have a self-locking mechanism to prevent the movable insert plate 62 from automatically extending or retracting during use. The through groove 91 provides stable guidance for the movable plate 92, allowing it to move linearly along the surface of the screw 82, thus maintaining high stability during the extension and retraction of the movable insert plate 62. The protective cover 100 protects the through groove 91 and screw 82, preventing gravel from entering and affecting their normal operation when used outdoors. Third-party loading tests show that under heavy-load train conditions with an axle load of 25t, this reinforcement structure reduces vertical track settlement by more than 50%, controls lateral displacement within 0.5mm, and increases the overall track load-bearing capacity by 40%, fully meeting the heavy-load (annual transport volume of over 15 million tons) and high-frequency (daily average of over 30 trains) transport requirements of dedicated railway lines.

[0023] In use, first place the base plate 1 next to the railway track, ensuring that the reinforcing plate 73 faces the track side. Then, anchor the base plate 1 to the ground foundation using the mounting holes 3 and M18 expansion bolts, tightening to a torque of 80-100 N·m. Next, the user pushes the L-shaped plate 61, causing the sliding block 51 to drive the protrusion 52 to slide within the guide groove 42 and anti-detachment groove 43 of the guide plate 41. Sliding stops when the reinforcing plate 73 initially approaches the track. Then, the user rotates the extended handle of the adjusting nut 83, driving the screw 82 to rotate within the shaft bracket 81. The screw 82, through threaded transmission, drives the moving plate 92 to move linearly along the through groove 91. Pull the movable insert plate 62 along the guide rod 63 to extend and retract until the arc-shaped notch of the reinforcing plate 73 is completely fitted with the groove at the bottom of the rail; then lock the reinforcing plate 73 to the rail with the connecting bolts 74, controlling the tightening torque at 80-100 N·m; finally, fasten the protective cover 100 to complete the installation of a single set of reinforcing structures; in actual construction, a set of reinforcing structures can be set every 1.2m according to the rail length, and multiple sets of coordinated support can form a continuous reinforcing system to further improve the rail bearing stability; after construction, the torque of all bolts must be re-inspected to ensure that it meets the design requirements, and regular inspections should be carried out every 3 months to tighten loose bolts in a timely manner.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
