Description

Technical Field

[0001] This utility model relates to the field of rail joint reinforcement technology, and in particular to an assembled rail joint reinforcement component. Background Technology

[0002] In railway transportation systems, rail joints are a critical component of the track structure, and their performance directly affects the safety and stability of train operation as well as the service life of the track. As the connection point between two adjacent rail sections, the rail joint must withstand repeated impacts and vibrations from train loads, as well as the expansion and contraction stresses caused by temperature changes, making it one of the most vulnerable parts of the track structure. To ensure the safety and stability of train operation and the service life of the track, reinforcement components need to be installed at the joints between adjacent rail sections.

[0003] Current rail joint reinforcement components mainly include fishplates (rail joint clamps), bolts, and nuts. During reinforcement, the fishplate is fixed to the rail web with bolts to reinforce the joint between the two rail sections. Although such reinforcement components are easy to install, the bolts are prone to loosening due to vibration during long-term operation. This not only seriously weakens the reinforcement effect on the rail joint but also significantly increases the frequency and cost of maintenance. Utility Model Content

[0004] This utility model relates to an assembled rail joint reinforcement component, which solves the problem that although current rail joint reinforcement components are easy to install, the bolts are prone to loosening due to vibration during long-term operation. This not only weakens the reinforcement effect of the rail joint, but also significantly increases the frequency and cost of maintenance.

[0005] In a first aspect, this utility model provides a prefabricated rail joint reinforcement assembly, specifically comprising: a reinforcement assembly installed at the joint position of two rails, with three second mounting holes at each of the two rail joint positions; the reinforcement assembly includes fishplates and fixing bolts, wherein there are two fishplates, located on the front and rear sides of the two rails respectively, each fishplate having six first mounting holes, and six fixing bolts, each of which is inserted into one of the six first mounting holes on the fishplate, with a fixing block at one end of each fixing bolt, and a nut threadedly connected to each fixing bolt; each fishplate is provided with three anti-loosening components, each anti-loosening component including a rectangular slide cylinder and a locking gear, the rectangular slide cylinder being fixedly connected to the fishplate, and a rectangular sliding block being slidably connected inside the rectangular slide cylinder, the head end of the rectangular sliding block having two locking engagement teeth, the locking gear being fixedly connected to the nut, and a stainless steel spring being provided inside the rectangular slide cylinder at the tail end of the rectangular sliding block.

[0006] Furthermore, the fixing bolt and the fixing block are an integrated structure, and the rectangular sliding block and the locking engagement tooth block are an integrated structure.

[0007] Furthermore, the three fixing blocks on the front side are welded to the front fishtail plate, and the three fixing blocks on the rear side are welded to the rear fishtail plate.

[0008] Furthermore, a limit block is fixedly connected to the outside of the rectangular sliding cylinder, and a rotating rod is rotatably connected to the rectangular sliding block via a rotating shaft.

[0009] Furthermore, when the anti-loosening component is in the locking and limiting state, the locking engagement tooth block meshes with the locking spline gear, and the rotating rod is stuck on the limiting block on one side surface near the head end of the rectangular slide cylinder.

[0010] Furthermore, a counterweight is provided at the lower end of the rotating rod.

[0011] This utility model provides a prefabricated rail joint reinforcement component, which has the following beneficial effects:

[0012] 1. This utility model, through the setting of the anti-loosening component, after the fixing bolt is tightened, rotates the rotating rod outward by 90 degrees, and then, under the action of the stainless steel spring, moves the locking engagement tooth block towards the locking spline gear, so that the locking engagement tooth block meshes with the locking spline gear. Through the meshing action of the locking engagement tooth block and the locking spline gear, the nut is effectively prevented from loosening. This not only improves the reinforcement effect of the rail joint, but also significantly reduces the frequency and maintenance cost of later maintenance.

[0013] 2. By setting up a rotating rod and a limiting block, this utility model can engage the locking meshing tooth block and the locking spline gear. Then, when the rotating rod is released, it automatically hangs down under the gravity of the counterweight block, so that the rotating rod is stuck on the side of the limiting block near the head end of the rectangular slide cylinder, which further limits the rectangular slide block and significantly improves the stability and reliability of the anti-loosening component.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figures 1 to 4 :

[0026] This utility model proposes an assembled rail joint reinforcement component, comprising: a reinforcement component 1, which is installed at the joint position of two rails 2, and each of the two rails 2 joint positions has three second mounting holes 201; the reinforcement component 1 includes fishplates 101 and fixing bolts 102, the number of fishplates 101 is two, and the two fishplates 101 are respectively located on the front and rear sides of the two rails 2, each fishplate 101 has six first mounting holes 105, the number of fixing bolts 102 is six, and the six fixing bolts 102 are respectively inserted into the six first mounting holes 105 on the fishplate 101, one end of the fixing bolt 102 is provided with a fixing block 103, and the fixing bolt 102 is threadedly connected with a nut 104; each fishplate 101... Each of the rails 101 is equipped with three anti-loosening components 3. Each anti-loosening component 3 includes a rectangular slide cylinder 301 and a locking gear 302. The rectangular slide cylinder 301 is fixedly connected to the fishplate 101, and a rectangular slide block 303 is slidably connected inside the rectangular slide cylinder 301. Two locking engagement teeth 304 are provided at the head end of the rectangular slide block 303. The locking gear 302 is fixedly connected to the nut 104. A stainless steel spring 307 is provided inside the rectangular slide cylinder 301 at the tail end of the rectangular slide block 303. After the fixing bolt 102 is tightened, the locking engagement teeth 304 and the locking gear 302 effectively prevent the nut 104 from loosening. This not only improves the reinforcement effect of the rail joint 2, but also significantly reduces the frequency and cost of later maintenance.

[0027] The fixing bolt 102 and the fixing block 103 are integrated structures, which gives the fixing bolt 102 and the fixing block 103 better connection strength and improves the reliability of the fixing bolt 102 when fixing the two fishtail plates 101. The rectangular sliding block 303 and the locking engagement tooth block 304 are integrated structures, which gives the rectangular sliding block 303 and the locking engagement tooth block 304 better strength and improves the reliability of the locking engagement tooth block 304 when locking and limiting.

[0028] The three front fixing blocks 103 are welded to the front fishtail plate 101, and the three rear fixing blocks 103 are welded to the rear fishtail plate 101, so that the fixing bolts 102 are effectively fixed on the fishtail plate 101.

[0029] Example 2, based on Example 1, such as Figures 1 to 4As shown, a limiting block 306 is fixedly connected to the outside of the rectangular slide cylinder 301, and a rotating rod 305 is rotatably connected to the rectangular slide block 303 via a rotating shaft. When the anti-loosening component 3 is in the locking and limiting state, the locking engagement tooth block 304 meshes with the locking spline gear 302, and the rotating rod 305 is stuck on the side of the limiting block 306 near the head end of the rectangular slide cylinder 301, thereby further limiting the rectangular slide block 303 and significantly improving the stability and reliability of the anti-loosening component 3.

[0030] A counterweight 308 is provided at the lower end of the rotating rod 305.

[0031] The working principle of this embodiment is as follows: During assembly, firstly, three fixing bolts 102 are inserted into each fishplate 101. Then, three fixing blocks 103 on the front side are welded to the front fishplate 101, and three fixing blocks 103 on the rear side are welded to the rear fishplate 101. Then, the two fishplates 101 are placed on the front and rear sides of the joint of the two rails 2. During this process, the three fixing bolts 102 on the front fishplate 101 are inserted backward into the corresponding first mounting hole 105 and second mounting hole 201. Then, the three fixing bolts 102 on the rear fishplate 101 are inserted forward into the corresponding first mounting hole 105. 05 and the second mounting hole 201; then rotate the rotating rod 305 outward by ninety degrees, and then move the rotating rod 305 towards the tail of the rectangular slide cylinder 301, moving the head end of the rectangular sliding block 303 into the rectangular slide cylinder 301. Then rotate the rotating rod 305 downward, so that the rotating rod 305 is locked on the side of the limiting block 306 away from the head end of the rectangular slide cylinder 301, so that the rectangular sliding block 303 is limited. Then tighten the nut 104 onto the fixing bolt 102, so that the two fishplates 101 are effectively fixed at the joint of the two rails 2, thereby reinforcing the joint of the two rails 2.

[0032] After tightening the fixing bolt 102, rotate the rotating rod 305 outward by 90 degrees. At this time, the rectangular sliding block 303 loses its limiting function. Then, under the elastic force of the stainless steel spring 307, it moves the locking engagement tooth block 304 towards the locking spline gear 302, so that the locking engagement tooth block 304 engages with the locking spline gear 302. Then, release the rotating rod 305. Under the gravity of the counterweight block 308, the rotating rod 305 automatically droops, thus locking the rotating rod 305 into the limiting block 3. On the side surface of the rectangular sliding cylinder 301 near the head end, the rectangular sliding block 303 is further limited, and the locking engagement tooth block 304 and the locking spline 302 effectively prevent the nut 104 from loosening. Since the fixing block 103 is welded to the fishplate 101, the fixing bolt 102 can also be effectively fixed. This not only improves the reinforcement effect of the rail 2 joint, but also greatly reduces the frequency and cost of maintenance.
