Description

Technical Field

[0001] The invention relates to the technical field of railway turnouts, and in particular to a mounting mechanism for a turnout external locking device. Background Art

[0002] A turnout is a line connection device that allows trains to switch from one track to another. It is also one of the weak links of the track and is usually laid in large quantities at stations and marshalling yards. By setting up turnouts, the line's capacity for passing trains can be fully utilized.

[0003] Common single-opening turnouts include two base rails and two point rails at intervals. The two point rails are located between the two base rails. When switching tracks, one of the point rails is in close contact with the base rail next to it, and the other point rail is separated from the base rail next to it. After the track is switched, the base rail and the point rail are locked by a locking device to prevent movement. The locking device is connected to the base rail and the point rail through a corresponding mounting mechanism.

[0004] The close fit between the point rail and the base rail is an important step after switching tracks. The locking device and the corresponding installation mechanism must have the function of adjusting the close fit of the point rail. During the installation, commissioning and regular maintenance of the existing locking device, the measures taken for adjusting the close fit between the point rail and the base rail are usually: adding or reducing adjustment pieces to make the close fit between the point rail and the base rail meet the industry standards, which is inconvenient to operate.

[0005] Point rail creep refers to a certain displacement of the point rail relative to other structures, and the displacement exceeds the standard value. It is a common turnout defect, especially for large-sized turnouts. The longer the point rail, the greater the creeping distance. In addition, the base rail will also deform due to factors such as thermal expansion and contraction. The existing locking device installation mechanism has poor adaptability to point rail creep and base rail deformation, resulting in greater stress on the locking device. Summary of the invention

It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0044] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] like Figures 1 to 3 As shown, this embodiment provides a mounting mechanism of a turnout external locking device, which is used to mount a locking device 100 on a stock rail 200 and a point rail 300. The mounting mechanism of the turnout external locking device includes a first mounting assembly 1, a second mounting assembly 2 and a locking assembly 3.

[0048] See also Figure 3, wherein the locking device 100 comprises a first locking sleeve 101 and a second locking sleeve 102. The first locking sleeve 101 is mounted on the base rail 200 through a first mounting assembly 1. The second locking sleeve 102 is mounted on the point rail 300 through a second mounting assembly 2, and the second locking sleeve 102 is movably inserted into the first locking sleeve 101. When the second locking sleeve 102 moves, it can drive the point rail 300 to move synchronously, so that the point rail 300 is closely attached to or repelled from the corresponding base rail 200.

[0049] See also Figure 1 and Figure 2 Each turnout includes two sets of rails spaced apart. Each set of rails includes a point rail 300 and a base rail 200. The two point rails 300 spaced apart are disposed between the two base rails 200. When one of the point rails 300 is in close contact with the base rail 200 outside the point rail 300, the other point rail 300 is separated from the base rail 200 outside the point rail 300 to achieve track switching. Assuming that the turnout in this embodiment has the ability to switch between track A and track B, see Figure 1 , the point rail 300 in the left guide rail group is away from the base rail 200, and the point rail 300 is in a repelling position, and the point rail 300 in the right guide rail group is close to the base rail 200, and the point rail 300 is in a close contact position. At this time, track A can pass trains. Figure 2 , the pointed rail 300 in the left guide rail group is close to the basic rail 200, and the pointed rail 300 is in a close position, and the pointed rail 300 in the right guide rail group is away from the basic rail 200, and the pointed rail 300 is in a repelling position. At this time, track B is accessible to trains.

[0050] The point rail 300 and the base rail 200 in each group are connected by a locking device 100, and the two locking devices 100 are installed on the base rail 200 and the point rail 300 by corresponding first mounting components 1 and second mounting components 2. The locking device 100 also includes a force transmission locking rod 103, which is inserted and connected in the second locking sleeve 102. The force transmission locking rods 103 on the two locking devices 100 are connected by a distance adjustment rod 4 to achieve synchronous movement of the two point rails 300.

[0051] See also Figure 3 and Figure 5The second mounting assembly 2 includes a second pin shaft 21 and an adaptive adjustment member 22. The second pin shaft 21 is connected to the side of the point rail 300 facing away from the base rail 200. One end of the adaptive adjustment member 22 is sleeved on the second pin shaft 21, and the other end is sleeved on the second locking sleeve 102, and the position relative to the second locking sleeve 102 is adjustable. After the turnout completes the switching of the tracks, the position of the adaptive adjustment member 22 can be adjusted by the second locking sleeve 102, so that the point rail 300 is driven by the second locking sleeve 102 and moves along the axial direction of the second locking sleeve 102, that is, the close adjustment of the point rail 300 is achieved, so that the gap between the point rail 300 and the corresponding base rail 200 meets the industry standard, and there is no need to use the traditional method of adding or reducing the adjustment sheet to adjust the point rail 300, which saves time and effort, and the operation is more convenient and quick. When the pointed rail 300 is adjusted to fit tightly, the locking assembly 3 is used to lock the adaptive adjusting member 22 and the second locking sleeve 102 to prevent the adaptive adjusting member 22 from axially moving relative to the second locking sleeve 102, thereby ensuring that the pointed rail 300 is reliable and stable after fitting tightly.

[0052] Further, see Figure 4 The first mounting assembly 1 includes a first pin shaft 11 connected to the outside of the base rail 200. The first locking sleeve 101 is provided with a mounting ring 1011, which is sleeved on the first pin shaft 11 and can rotate relative to the base rail 200. When the base rail 200 is affected by thermal expansion and contraction or deformed by external impact loads, the mounting ring 1011 and the first locking sleeve 101 connected thereto can rotate relative to the base rail 200 to adapt to the deformation of the base rail 200. At the same time, the adaptive adjustment member 22 connected to the second locking sleeve 102 can rotate relative to the point rail 300. When the point rail 300 creeps, the adaptive adjustment member 22 can drive the second locking sleeve 102 fixedly connected thereto to rotate relative to the point rail 300 to adapt to the creeping of the point rail 300.

[0053] The first mounting assembly 1 and the second mounting assembly 2 in the device work together, which can not only conveniently and quickly realize the close adjustment of the point rail 300, but also automatically adapt to the creeping of the point rail 300 and the deformation of the base rail 200, so as to ensure that the locking devices 100 corresponding to the two pairs of point rails 300 and the base rail 200 in the turnout are always in the same straight line, so as to avoid large stress on the entire locking device 100, the first mounting assembly 1 and the second mounting assembly 2.

[0054] Alternatively, see Figure 6, a first threaded hole 221 is provided at one end of the adaptive adjustment member 22 away from the second pin shaft 21. A first external thread is provided on the outer wall of the second locking sleeve 102, and the second locking sleeve 102 is screwed into the first threaded hole 221 to be threadedly connected with the adaptive adjustment member 22. When it is necessary to adjust the point rail 300 closely, the second locking sleeve 102 is screwed, and the second locking sleeve 102 rotates along the axis in the first locking sleeve 101 without axial movement. Therefore, the adaptive adjustment member 22 can move along the axial direction of the second locking sleeve 102 to drive the point rail 300 to move synchronously axially, thereby adjusting the gap between the point rail 300 and the base rail 200. Compared with the method of adding or reducing the adjustment sheet in the prior art, this method is simpler and more convenient to operate. The close adjustment of the point rail 300 can be achieved by screwing the second locking sleeve 102, which saves time and effort.

[0055] Further, see Figure 5 Six planes of the same size are arranged at intervals along the circumferential direction on the second locking sleeve 102, which can be adapted to the shape of the wrench bayonet, so that the second locking sleeve 102 can be screwed by the wrench, which is easy to operate.

[0056] See also Figure 5 and Figure 6 Optionally, the adaptive adjusting member 22 is provided with a first extension portion 222 and a second extension portion 223. The first extension portion 222 and the second extension portion 223 are both convexly arranged at the position of the first threaded hole 221. The locking assembly 3 includes a locking bolt 31 and a locking nut 32. The locking bolt 31 passes through the first extension portion 222 and the second extension portion 223 in sequence and is connected to the locking nut 32. When the locking nut 32 is not tightened, screwing the second locking sleeve 102 can make the adaptive adjustment member 22 drive the point rail 300 to move. When the gap between the point rail 300 and the base rail 200 is adjusted appropriately, tighten the locking nut 32 to bring the first extension portion 222 and the second extension portion 223 closer (this displacement is small), and the diameter of the first threaded hole 221 is slightly reduced so that the adaptive adjustment member 22 can clamp the second locking sleeve 102. At this time, the hole wall of the first threaded hole 221 is pressed against the outer wall of the second locking sleeve 102 to prevent the first external thread on the second locking sleeve 102 from being screwed relative to the first threaded hole 221, so as to avoid the point rail 300 that has been adjusted closely moving again.

[0057] Continue reading Figure 5 and Figure 6Optionally, the second mounting assembly 2 further includes a point rail connector 23. The point rail connector 23 includes a first connecting portion 231 and a second connecting portion 232 connected to each other, the first connecting portion 231 being detachably connected to the point rail 300, and the second pin 21 being embedded in the second connecting portion 232. In this embodiment, the first connecting portion 231 and the second connecting portion 232 form a T-shaped structure, the first connecting portion 231 being the head of the T-shaped structure, and the dimension thereof along the extension direction of the point rail 300 being larger than the dimension of the second connecting portion 232 along the extension direction of the point rail 300, which can increase the contact area between the second mounting assembly 2 and the point rail 300 and improve the stability after connection. The second connecting portion 232 is the vertical portion of the T-shaped structure, which is arranged between the first connecting portion 231 and the adaptive adjusting member 22. The second pin 21 is embedded in the second connecting portion 232, which can improve the connection strength and stability between the two and avoid loosening due to impact load.

[0058] Alternatively, see Figure 5 The first connection part 231 is detachably connected to the point rail 300 through the first bolt 27, which is convenient to install and disassemble, and the connection is reliable and not easy to loosen. Specifically, a first bolt 27 is set on the opposite sides of the second connection part 232, and the two first bolts 27 penetrate the point rail 300 and the first connection part 231, and are threadedly connected with the corresponding nuts. The entire point rail connector 23 can be fixed to the point rail 300 by tightening the nuts. Of course, the number of first bolts 27 is not limited to two.

[0059] See also Figure 7 , the adaptive adjusting member 22 is provided with a strip hole 224, and the second pin 21 is passed through the strip hole 224 and slidably cooperates with the strip hole 224. When the point rail 300 is in a normal state, the adaptive adjusting member 22 is vertically arranged, and the strip hole 224 extends vertically. At this time, the locking device 100 and the strip hole 224 are on the same vertical line, and the second pin 21 is located in the middle position of the strip hole 224, that is, the second pin 21 has a certain sliding space in the strip hole 224, either upward or downward.

[0060] contrast Figure 8 and Figure 7 The positions of the center rail 300 and the stock rail 200 show that Figure 8The point rail 300 in the structure creeps rightward relative to the base rail 200, and the point rail 300 drives the upper end of the adaptive adjusting member 22 to move rightward through the second pin shaft 21, while the lower end of the adaptive adjusting member 22 is fixed to the second locking sleeve 102 through the locking assembly 3, so there is no relative rotation, that is, the lower end of the adaptive adjusting member 22 and the second locking sleeve 102 only rotate along their own axis in the original position (the second locking sleeve 102 rotates in the first locking sleeve 101), which will not affect the close contact state of the point rail 300. At the same time, in order to adapt to the rightward movement of the point rail 300, the bar hole 224 on the adaptive adjusting member 22 is slidably matched with the second pin shaft 21.

[0061] contrast Fig. 9 and Figure 7 The positions of the center rail 300 and the stock rail 200 show that Fig. 9 The pointed rail 300 creeps to the left relative to the basic rail 200, and the pointed rail 300 drives the upper end of the adaptive adjustment member 22 to move to the left through the second pin shaft 21, while the lower end of the adaptive adjustment member 22 and the second locking sleeve 102 only rotate along their own axes in the original position. At the same time, in order to adapt to this movement, the strip hole 224 on the adaptive adjustment member 22 slides with the second pin shaft 21.

[0062] See also Figure 4 The first mounting assembly 1 further comprises a mounting body 12, which is detachably connected to the base rail 200. Specifically, the mounting body 12 is detachably connected to the base rail 200 by two second bolts 17. A first mounting block 13 and a second mounting block 14 are convexly provided on a side of the mounting body 12 facing away from the base rail 200. The first mounting block 13 and the second mounting block 14 are arranged at intervals along the extending direction of the base rail 200. The first mounting block 13 and the second mounting block 14 are both connected to the base rail 200 by a hook bolt 18. Taking the first mounting block 13 as an example, the hook bolt 18 comprises a connected screw rod and a hooking portion. When connected, the hooking portion of the hook bolt 18 is hooked and clamped on a side of the base rail 200 facing away from the first mounting block 13. The screw rod passes through the bottom of the base rail 200 and penetrates the first mounting block 13, and then is threadedly connected with a corresponding nut. By tightening the nut, the first mounting block 13 and the base rail 200 can be fixed.

[0063] Continue reading Figure 4, the first pin shaft 11 passes through the first mounting block 13 and the second mounting block 14, the mounting ring 1011 is located between the first mounting block 13 and the second mounting block 14, and is sleeved on the first pin shaft 11. Further, a second joint bearing 15 is arranged between the mounting ring 1011 and the first pin shaft 11, the mounting ring 1011 is sleeved on the first pin shaft 11 through the second joint bearing 15, and there are gaps between the second joint bearing 15 and the first mounting block 13, and between the second joint bearing 15 and the second mounting block 14. That is, there is a certain amount of activity space on both sides of the second joint bearing 15, so that the mounting ring 1011 and the locking device 100 connected thereto can be adaptively deflected to adapt to the deformation caused by factors such as thermal expansion and contraction of the base rail 200 or impact load.

[0064] Accordingly, see Figure 5 and Figure 6 , first joint bearings 24 and elastic members 25 are provided on both sides of the adaptive adjustment member 22. The first joint bearings 24 and the elastic member 25 are both sleeved on the second pin shaft 21, and the elastic member 25 is located on the side of the first joint bearing 24 away from the adaptive adjustment member 22. The adaptive adjustment member 22 is arranged between the two first joint bearings 24. When the basic rail 200 is deformed, the adaptive adjustment member 22 and the locking device 100 connected thereto are adaptively deflected. The first joint bearing 24 and the second joint bearing 15 cooperate with each other and work together to adapt to the deformation of the basic rail 200 caused by thermal expansion and contraction or impact loads. At the same time, the adaptive deflection ability can make the two locking devices 100 and the distance adjustment rod 4 connecting the two locking devices 100 always in the same straight line. The first joint bearing 24 can be an angular contact joint bearing.

[0065] See also Figure 2 Due to the presence of the first spherical bearing 24 and the second spherical bearing 15 , the two locking devices 100 can be deflected by an angle a in two opposite directions when the stock rail 200 is deformed.

[0066] Continue reading Figure 5 and Figure 6 A stopper 26 is provided on the outer side of an elastic member 25 away from the point rail 300. The stopper 26 abuts against the elastic member 25, so that the two elastic members 25 are given a preset pressure when installed, that is, the two elastic members 25 are in a compressed state when installed. At this time, the two first joint bearings 24 can clamp the adaptive adjustment member 22 under the pressure of the corresponding elastic member 25, so that the adaptive adjustment member 22 can play a buffering role when adaptively deflecting, reduce the impact, and ensure the stability of the adaptive adjustment member 22 and the point rail connector 23 after installation.

[0067] Preferably, in this embodiment, the elastic member 25 is a disc spring group formed by stacking a plurality of disc spring sheets. The disc spring group can bear a large load in a small space and has good buffering and shock absorbing capabilities.

[0068] Optionally, in this embodiment, the ends of the force transmission locking rods 103 of the two locking devices 100 close to each other are both provided with a second threaded hole. The pitch adjustment rod 4 is provided with a second external thread at one end and a third external thread at the other end, and the two force transmission locking rods 103 are both threadedly connected to the pitch adjustment rod 4. The second external thread and the third external thread are rotated in opposite directions. When the pitch adjustment rod 4 is screwed, the two force transmission locking rods 103 are moved closer to each other or farther away from each other. The force transmission locking rod 103 can drive the second locking sleeve 102 sleeved thereon to move closer to each other or farther away from each other, thereby achieving the mutual approach or repulsion of the two locking devices 100, so that the spacing between the two locking devices 100 is appropriately adjusted, so that the opening amount between the point rail 300 and the base rail 200 (i.e., the spacing between the point rail 300 and the base rail 200) meets the standard of the turnout, the operation is convenient and labor-saving, and the production and processing of the internal thread and the external thread are relatively simple, avoiding the addition of cumbersome processes.

[0069] See also Figure 1 The distance adjusting rod 4 is provided with a screwing portion 41 , which is matched with the shape of the wrench bayonet. By engaging the bayonet of the wrench with the screwing portion 41 , the distance adjusting rod 4 can be screwed to adjust the distance between the two locking devices 100 .

[0070] Further, see Figure 1 and Figure 2 , a locking nut 5 is sleeved on the pitch-adjusting rod 4. The locking nut 5 can match the second external thread or the third external thread. When the spacing between the two locking devices 100 is adjusted appropriately (the second external thread and / or the third external thread is located outside the force-transmitting locking rod 103), the locking nut 5 is tightened on the second external thread or the third external thread to play a fixing role, prevent the force-transmitting locking rods 103 of the two locking devices 100 from relative movement with the pitch-adjusting rod 4, and improve stability.
