When in use, the connecting hole of the connecting block 13 can be connected to the sleeper or the ground by bolts, which can provide an effective fixing effect for the side plate 11, and a side shell 12 is provided on the other side of the rail 1, and the side plate 11 and the side shell 12 are both made of cast iron, which has high hardness and wear resistance, and a through hole 2 is provided on the waist of the rail 1, and the number of the through holes 2 is There are two rails 1, a first through hole 3 is formed on the surface of the side plate 11, and second through holes 4 are formed on both sides of the surface of the side shell 12. The first through hole 3 and the second through hole 4 are used in conjunction with the through hole 2. Since there are two rails 1, the first through hole 3 and the second through hole 4 are both four in number. The sizes and positions of the through hole 2, the first through hole 3 and the second through hole 4 correspond to each other. A hexagonal bolt 6 is provided on one side of the first through hole 3. The number of the hexagonal bolts 6 is four. The threaded end of the hexagonal bolt 6 can extend to the inner cavity of the side shell 12 through the first through hole 3, the through hole 2 and the second through hole 4. The inner cavity of the side shell 12 is provided with a worm gear 5, and the worm gear 5 is a circular ring structure. The number and position of the worm gear 5 and the hexagonal bolt 6 correspond to each other. The inner cavity of the side shell 12 is provided with a fastening mechanism 7. The worm gear 5 and the fastening mechanism 7 are used together to enable the worm gear 5 to rotate synchronously on the threaded surface of the hexagonal bolt 6, so that the side plate 11 and the side shell 12 can simultaneously tightly fit and clamp the two sides of the two sections of the rail 1, provide support and fixation for the two sections of the rail 1, prevent the two sections of the rail 1 from displacement and fracture when the train is running, thereby improving the continuity and flatness of the rail 1 as a whole. The outer side of the side shell 12 is provided with an anti-loosening mechanism 8. The anti-loosening mechanism 8 is used in conjunction with the fastening mechanism 7 to avoid the fastening mechanism 7 from being loosened when the hexagonal bolt is in contact with the hexagonal bolt. After the bolt 6 is tightened, if it accidentally loosens due to vibration or impact caused by the train running, the anti-loosening mechanism 8 can provide additional safety to avoid the risk of breakage between the rails 1. An auxiliary mechanism 9 is provided on the surface of the rail 1. The auxiliary mechanism 9 is used in conjunction with the side plate 11 and the side shell 12, which can not only improve the stability of the connection between the rail 1 and the side plate 11 and the side shell 12, but also can disperse the vibration and impact force generated when the train runs on the rail 1 and transmit it to the side plate 11 and the side shell 12, which can effectively reduce the impact of the impact force on the rail 1 and can further prevent the breakage between the rails 1, thereby improving the safety of train operation.
[0027] The fastening mechanism 7 includes a rotating rod 71, which is located below the inner cavity of the side shell 12. One end of the rotating rod 71 is rotatably connected to the inner wall of the side shell 12 through a bearing seat, and the other end of the rotating rod 71 penetrates to the outside of the side shell 12 and is rotatably connected to the penetration point through a bearing sleeve. The other end of the rotating rod 71 is fixedly connected to an external hexagonal head 75. The size of the external hexagonal head 75 is a standard configuration of a hexagonal head bolt, and it can be rotated using an external hexagonal wrench. The surface of the rotating rod 71 is provided with worm patterns 72. The number and position of the worm patterns 72 correspond to those of the worm wheel 5, and they mesh with each other. The inner side of the worm wheel 5 is fixedly connected to a rotating cylinder 73, and the interior of the rotating cylinder 73 is provided with an internal thread, and it forms a screw thread with the worm wheel 5. The cap structure, the hexagonal bolt 6 is threadedly connected to the inner wall of the rotating cylinder 73, the surfaces of the two ends of the rotating cylinder 73 are provided with recesses, and annular grooves 74 are provided on both sides of the inner wall of the side shell 12. The annular grooves 74 match the shape of one end of the rotating cylinder 73 and are slidably connected to each other. When the external hexagonal head 75 is rotated by a wrench, the rotating rod 71 and the worm pattern 72 can be rotated, and the worm pattern 72 can mesh and rotate the worm wheel 5, so that the rotating cylinder 73 inside the worm wheel 5 slides and rotates in the annular groove 74, so that all the worm wheels 5 can rotate synchronously in the same direction in the inner cavity of the side shell 12. The inner wall of the side shell 12 is fixedly connected with a support plate 10, and the center of the support plate 10 is rotatably connected to the surface of the rotating rod 71 through a bearing sleeve. , which can provide a supporting effect for the rotating rod 71, so that the rotating rod 71 drives the worm pattern 72 to mesh with the worm wheel 5 and rotate more smoothly. A hexagonal groove 76 is provided on one side of the side plate 11, and the hexagonal groove 76 is communicated with the first through hole 3. The hexagonal groove 76 matches the size of the hexagonal head at one end of the hexagonal bolt 6. When the hexagonal head of the hexagonal bolt 6 is stuck in the inner wall of the hexagonal groove 76, the hexagonal bolt 6 can be limited to prevent it from rotating. When the worm wheel 5 rotates, the threaded connection between the hexagonal bolt 6 and the center of the rotating drum 73 can make the worm wheel 5 move along the threaded surface of the hexagonal bolt 6, and the sliding connection between the rotating drum 73 and the inner wall of the annular groove 74 can drive the side shell 12 to the rail 1 side. The waist of the rail 1 moves close to and fits tightly. At this time, with the cooperation of the hexagonal head of the hexagonal bolt 6 and the hexagonal groove 76, the side plate 11 can be synchronously moved close to and fit tightly to the waist of the rail 1 on the other side. At the same time, the meshing rotation of the worm pattern 72 and the worm wheel 5 has a good self-locking effect, which can prevent the worm wheel 5 from accidentally rotating and causing the hexagonal bolt 6 to loosen, thereby improving the fitting and clamping effect of the side plate 11 and the side shell 12 on both sides of the waist of the rail 1. Accordingly, the side plate 11 and the side shell 12 can fit and clamp both sides of the two sections of the rail 1, provide fixation and protection for the waist part of the two sections of the rail 1, effectively prevent the displacement and breakage of the two sections of the rail 1 when the train is running, and improve the safety of the railway line.
[0028] The anti-loosening mechanism 8 includes a support 81, which is bolted to one side of the side shell 12. An L-shaped blocking rod 82 is rotatably connected between the support 81 through a rotating shaft. The L-shaped blocking rod 82 is used in conjunction with the external hexagonal head 75. A magnet 83 is installed at the bottom of the L-shaped blocking rod 82. By turning the magnet 83, the L-shaped blocking rod 82 can be rotated around the rotating shaft of the support 81. When the L-shaped blocking rod 82 rotates to the bottom of the external hexagonal head 75, the top of the L-shaped blocking rod 82 will contact and fit with the bottom surface of the external hexagonal head 75, which can provide a limiting effect for the external hexagonal head 75 to prevent it from rotating, thereby further preventing the rotating rod 71 and the worm pattern 72 from accidentally rotating. At this time, the magnet 83 will The surfaces of the cast iron side shells 12 generate magnetic attraction to each other, which can keep the limiting state of the L-shaped stopper 82 stable, thereby improving the stability of the L-shaped stopper 82 limiting the external hexagonal head 75. When the external hexagonal head 75 needs to be twisted with a wrench, it is only necessary to pull the magnet 83 away from the magnetic attraction with the side shell 12, and then the L-shaped stopper 82 is rotated in the opposite direction away from the external hexagonal head 75 until it is rotated to the other side of the side shell 12. This will not affect the staff's rotation of the external hexagonal head 75. Therefore, even if the train is subject to vibration and impact during long-term travel, the anti-loosening mechanism 8 can still provide additional safety, which can further avoid the risk of breakage between the rails 1.
[0029] The auxiliary mechanism 9 includes a T-shaped block 91, which is welded to the lower jaw of one side of the rail 1, and a clamping block 93 is welded to the lower jaw of the other side of the rail 1. Since there are two rails 1, there are two clamping blocks 93 and T-shaped blocks 91. A T-shaped slot 92 is provided on the top of the side shell 12. The number and position of the T-shaped slots 92 and the T-shaped blocks 91 correspond to each other and are slidably connected to each other. A clamping slot 94 is provided on the top of the side plate 11. The number and position of the clamping slot 94 and the clamping block 93 match each other and are slidably connected to each other. When in use, the T-shaped block 91 is inserted into the inner wall of the T-shaped slot 92, and the clamping block 93 is inserted into the inner wall of the clamping slot 94. The vibration and impact force generated by the rail head part of the rail 1 when the train is running can be transmitted and dispersed to the side plates 11 and the side shells 12 on both sides, which can reduce the vibration and impact force directly received by the rail 1, and can further reduce the fracture between the rails 1, thereby improving the reliability and safety of the railway track system.
[0030] Working principle: first, insert the block 93 into the slot 94, and fit the side plate 11 with one side of the waist of the two sections of the rail 1, then insert the T-shaped block 91 into the block 93, and make the side shell 12 close to the other side of the waist of the two sections of the rail 1, then extend the threaded ends of the four hexagonal bolts 6 through the first through hole 3, the through hole 2 and the second through hole 4 to the inner cavity of the side shell 12, and make the hexagonal bolts 6 correspond to the central threaded hole of the worm gear 5, then insert the hexagonal head at one end of the hexagonal bolt 6 into the inner wall of the hexagonal groove 76 to prevent it from rotating, and then use a wrench to rotate the outer hexagonal head 75 to rotate the rotating rod 71 and the worm pattern 72, so that the worm pattern 72 engages with the worm wheel 5 to rotate it, and the rotating drum 73 can rotate and move along the threaded surface of the hexagonal bolt 6, and at this time, the rotating drum 73 and the inner wall of the annular groove 74 are connected. The sliding connection can push the side shell 12 to move closer to the waist of the rail 1 on one side of the rail 1, and at the same time, with the cooperation of the hexagonal bolt 6 and the hexagonal groove 76, the side plate 11 and the side shell 12 can be synchronously clamped on both sides of the two sections of the rail 1, which can provide a fixing effect for the waist of the two sections of the rail 1 and prevent the two sections of the rail 1 from breaking. When the external hexagonal head 75 is to be limited, the L-shaped stopper 82 is first rotated to the bottom of the external hexagonal head 75 so that it fits with the bottom surface of the external hexagonal head 75, which can prevent the external hexagonal head 75 from accidentally rotating. The magnet 83 and the cast iron side shell 12 generate magnetic attraction, which can improve the stability of the L-shaped stopper 82. Finally, the connecting hole of the connecting block 13 is connected to the sleeper or the ground by bolts, which can provide additional fixing and supporting effects for the fastening clamp.
