Description

Technical Field

[0001] This utility model belongs to the field of track reinforcement technology, and in particular relates to an internal support component of a turnout rail reinforcement device. Background Technology

[0002] Turnouts are important pieces of equipment on railway lines. They are used to connect two tracks running in different directions and are one of the key devices to ensure railway traffic safety.

[0003] The patent with publication number CN118087322A discloses a non-destructive reinforcement device for turnout rails, including a top support member supported between the stock rail and the switch rail. The top support member consists of a top support rod and a top support column that are threaded together, and an adjusting nut is threadedly connected to the top support rod.

[0004] However, in actual use, the passage of trains will cause severe vibrations in the rails. As the service time increases, the top support rod, top support column and adjusting nut, which are only connected by threads, are prone to loosening. This causes the connection between the top support and the stock rail and switch rail to loosen, weakening the reinforcement effect between the stock rail and switch rail and reducing the safety of vehicle operation.

[0005] Therefore, it is necessary to improve the internal support components in the existing technology. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects in the existing technology and provide an internal support component of a turnout rail reinforcement device to improve the reinforcement effect between the stock rail and the switch rail.

[0007] To achieve the above objectives, the specific technical solution for the internal support component of the turnout rail reinforcement device of this utility model is as follows:

[0008] An internal support component of a turnout rail reinforcement device includes a stud, on which a threaded sleeve and a locking nut are threadedly connected. A groove is formed on the side of the stud along its own axial direction. A limit block is slidably disposed in the groove. The front end face of the limit block abuts against the end face of the threaded sleeve. The locking nut is provided with a protrusion, which limits the mutual positioning with the limit block to prevent the locking nut from rotating.

[0009] Preferably, the front opening of the locking nut is provided with a tapered surface, and the convex strips are evenly distributed on the tapered surface around the axis of the tapered surface, and the convex strips are distributed along the generatrix direction of the tapered surface.

[0010] Preferably, the top surface of the limiting block is an inclined surface, and both sides of the inclined surface are provided with rounded corners. The height of the front end of the limiting block is greater than the depth of the slide groove, and the height of the end of the limiting block is less than the depth of the slide groove.

[0011] Preferably, the limiting block has a U-shaped structure, and the U-shaped opening of the limiting block is parallel to the axial direction of the stud.

[0012] Preferably, an elastic support member is provided inside the U-shaped opening of the limiting block.

[0013] Preferably, one end of the stud is fixedly connected to an abutment seat.

[0014] Preferably, the side of the abutment seat opposite to the stud has a mounting groove, and a magnetic block is fixedly connected inside the mounting groove.

[0015] Preferably, the outer circumferential portion of the front end of the threaded sleeve is provided with a stepped portion.

[0016] Preferably, the upper and lower sides of the abutment seat are provided with chamfers, and the chamfers are located on the side of the abutment seat away from the stud.

[0017] The internal support component of the turnout rail reinforcement device of this utility model has the following advantages: the limiting block set inside the slide groove can abut against the end of the threaded sleeve to prevent the threaded sleeve from loosening; secondly, it mutually limits the movement of the locking nut with the protrusion on the locking nut, restricting the rotation of the locking nut and preventing the locking nut from loosening; and the locking nut can also limit the sliding of the limiting block, thereby realizing the locking between the limiting block, the locking nut and the threaded sleeve, reducing the probability of the internal support component loosening, and improving the support effect of the internal support component on the stock rail and switch rail.

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0026] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the inner support components and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] like Figure 1 and 2 As shown, an internal support component of a turnout rail reinforcement device includes a stud 2, a threaded sleeve 4 and a locking nut 3 threadedly connected to the stud 2. A groove 201 is provided on the side of the stud 2 along its own axial direction. A limit block 6 is slidably arranged in the groove 201. The front end face of the limit block 6 abuts against the end face of the threaded sleeve 4. The locking nut 3 is provided with a protrusion 302, which limits the lock nut 3 to prevent it from rotating.

[0028] When using a reinforcement device to reinforce turnout rails, the aforementioned inner support component is placed between the stock rail and the switch rail to support the two rails from the inside, thereby improving the stability of the reinforcement of the stock rail and the switch rail. In use, the length of the combination of the threaded sleeve 4 and the stud 2 can be adjusted by turning the threaded sleeve 4 so that it can be adapted to the distance between the stock rail and the switch rail. The ends of the threaded sleeve 4 and the stud 2 are distributed and abut against the web of the switch rail and the stock rail, supporting the two rails from the inside and achieving reinforcement between the two rails.

[0029] Compared to existing internal support components, the aforementioned internal support component has a sliding groove 201, and a limiting block 6 is provided inside the sliding groove 201. There are three sliding grooves 201, evenly spaced around the axis of the stud 2, thus providing three limiting blocks 6. By simultaneously supporting the threaded sleeve 4 with the three limiting blocks 6, the threaded sleeve 4 can be subjected to uniform force, improving its stability. The front end of the limiting block 6 abuts against the end of the threaded sleeve 4, limiting the threaded sleeve 4 and preventing it from sliding along the axial direction of the stud 2. The sliding groove 201 limits the limiting blocks 6, preventing them from extending perpendicular to the plant 201. The directional displacement allows the limiting block 6 and the protrusion 302 to mutually limit each other, preventing the locking nut 3 from rotating under vibration and reducing the probability of the locking nut 3 loosening. When the locking nut 3 is restricted by the limiting block 6, the locking nut 3 can also restrict the sliding of the limiting block 6 inside the slide groove 201, ultimately achieving mutual locking between the stud 2, locking nut 3, threaded sleeve 4, and limiting block 6. This reduces the probability of the inner support component loosening, maintains the support effect of the inner support component on the main rail and switch rail, improves the stability and reliability of the inner support component, and enhances the train's driving safety.

[0030] Further improvements include, for example Figure 5 and 6 As shown, a tapered surface 301 is provided at the front opening of the locking nut 3. Raised ribs 302 are evenly distributed around the axis of the tapered surface 301, with the raised ribs 302 distributed along the generatrix of the tapered surface 301. After the tapered surface 301 contacts the limiting block 6, it generates two component forces on the limiting block 6. One component force is radially towards the bottom of the groove 201 along the stud 2, and the other component force is axially towards the threaded sleeve 4 along the stud 2. This increases the static friction between the limiting block 6 and the bottom of the groove 201. Through friction and the component force towards the threaded sleeve 4, the sliding of the limiting block 6 within the groove 201 is better restricted, thereby improving the stability of the limiting block 6's support for the threaded sleeve 4. Ultimately, this improves the stability of the connection between the threaded sleeve 4 and the stud 2, reducing the probability of loosening of the inner support components.

[0031] Further improvements include, for example Figure 4As shown, the top surface of the limiting block 6 is an inclined surface 601, and both sides of the inclined surface 601 are rounded. The height of the front end of the limiting block 6 is greater than the depth of the slide groove 201, and the height of the end of the limiting block 6 is less than the depth of the slide groove 201. The inclination of the inclined surface 601 is consistent with the inclination of the conical surface 301, so that the inclined surface 601 can closely abut against the conical surface 301, increasing the contact range between the two, thereby improving the mutual limiting effect between the limiting block 6 and the protrusion 302; and the limiting block 6 with the inclined surface 601 can enter the inside of the locking nut 3, and engage with the protrusion 302 from the inside of the locking nut 3 to achieve mutual limiting. In this way, the locking nut 3 can abut against the threaded sleeve 4 to achieve mutual locking between the locking nut 3 and the threaded sleeve 4, further improving the stability of the connection between the threaded sleeve 4 and the stud 2, and improving the stability of the inner support component for the rail support.

[0032] Further improvements include, for example Figure 4 As shown, the limiting block 6 has a U-shaped structure, with the U-shaped opening of the limiting block 6 oriented parallel to the axial direction of the stud 2; an elastic support member 602 is provided inside the U-shaped opening of the limiting block 6. The U-shaped structure allows the limiting block 6 to be compressed along the axial direction of the stud 2, making it easier for the inclined surface 601 to engage between two adjacent protrusions 302 during the tightening process of the locking nut 3, thereby forming a mutual limiting structure; the elastic support member 602 is a disc spring, and the elastic force it generates can push the inclined surface 601 and the conical surface 301 to fit more stably and reliably, thereby effectively maintaining the mutual limiting effect between the limiting block 6 and the protrusions 302 under strong vibration, thus reducing the probability of the locking nut 3 loosening due to rotation, and thus improving the stability of the inner support component.

[0033] Further improvements include, for example Figure 3 As shown, one end of the stud 2 is fixedly connected to the abutment seat 1. The abutment seat 1 increases the contact area between the stud 2 and the web of the main rail, improves the stability of the connection between the stud 2 and the main rail, and thus improves the stability of the inner support component in supporting the rail.

[0034] Further improvements include, for example Figure 1-3 As shown, the side of the abutment 1 opposite to the stud 2 has an installation groove 102, and a magnetic block 5 is fixedly connected inside the installation groove 102. The magnetic block 5 is a permanent magnet. The magnetic block 5 can attract the abutment 1 to the web of the base rail, thereby improving the firmness of the connection between the inner support component and the base rail; and during the installation process, the magnetic block 5 can also be used to pre-fix the stud 2, which is convenient for subsequent tightening of the threaded sleeve 4, improving the ease of installation of the inner support component.

[0035] Further improvements include, for example Figure 3As shown, a stepped portion 401 is provided on the outer periphery of the front end of the threaded sleeve 4. The stepped portion 401 reduces the outer diameter of the front end of the threaded sleeve 4, thereby avoiding the upper and lower arcs of the web of the pointed rail, allowing the threaded sleeve 4 to fit tightly against the web of the pointed rail, thus improving the stability of the inner support component.

[0036] Further improvements include, for example Figure 2 As shown, chamfers 101 are provided on both the upper and lower sides of the abutment seat 1. The chamfers 101 are located on the side of the abutment seat 1 away from the stud 2. The chamfers 101 allow the abutment seat 1 to avoid the upper and lower arcs at the web of the base rail, thereby making the abutment seat 1 fit tightly against the web of the base rail and improving the stability of the inner support component.
