[0039] Reference Figures 1 to 7 , The utility model discloses a positioning and adjusting member for a railway turnout slide bed, which is used to be installed on a slide bed, and also includes a positioning member, which is connected to the slide bed, and the positioning member includes a positioning portion 2 and a mounting portion 21, and the mounting portion 21 is provided with a groove 22 along a first direction, and the mounting portion 21 and the groove 22 are symmetrically arranged about the central axis of the positioning portion 2, and the slide bed includes a bottom plate 1 mounted on the sleeper by bolts, and the bottom plate 1 is provided with a plurality of mounting holes 3 arranged at intervals along a first direction, the first direction is the same as the extension direction of the sleeper, and the width of the mounting hole 3 along the first direction is greater than the bolt diameter, the lower surface of the positioning portion 2 is arranged in contact with the upper surface of the bottom plate 1, the mounting portion 21 cooperates with the mounting hole 3, and the length direction of the mounting portion 21 is consistent with the first direction;

[0040] Adjacent inner walls of the grooves 22 are arranged perpendicular to each other.

[0041] First, the positioning member includes a positioning portion 2 and an installation portion 21. Grooves 22 are arranged on both sides of the installation portion 21 in the length direction, and the installation portion 21 and the groove 22 are symmetrically arranged about the central axis of the positioning portion 2. Such a design helps to disperse the stress generated between the connecting components. Through the arrangement of the groove 22, the force between the connecting components can be evenly distributed, reducing local stress concentration, thereby increasing the stability and durability of the connection.

[0042] Secondly, the slide bed includes a base plate 1, which is provided with a plurality of mounting holes 3 spaced apart along a first direction. The width of the mounting holes 3 along the first direction is greater than the diameter of the bolt. The lower surface of the positioning portion 2 is arranged in contact with the upper surface of the base plate 1, and the mounting portion 21 cooperates with the mounting hole 3. Such a design can ensure that the connecting components are subjected to balanced force, avoid excessive local stress, and improve the stability and safety of the connection.

[0043] Finally, grooves 22 are provided on both sides of the length direction of the mounting portion 21. The design of the grooves 22 helps to disperse the stress generated between the connecting parts, so that the force in the extension direction of the rail is evenly distributed. This design can reduce errors during the installation process, ensure the accuracy and stability of the assembly, and increase the stability and durability of the connection.

[0044] The U-shaped design of the groove 22 can effectively enhance the fixing performance between the positioning piece and the slide bed plate. Since the inner walls of the U-shaped groove 22 are arranged perpendicular to each other, they can provide greater resistance and support force, ensuring that the positioning piece will not easily fall off or loosen after installation. The setting of the groove 22 helps to disperse the stress generated between the connecting parts. When the positioning piece is connected to the slide bed plate, the groove 22 can help evenly distribute the force between the connecting parts, reduce local stress concentration, and improve the stability and durability of the connection. The regular U-shaped design of the groove 22 can provide better fit, making the installation between the positioning piece and the slide bed plate smoother and more convenient. The shape of the groove 22 can ensure that the mounting portion 21 is correctly aligned in the mounting hole 3, simplifying the installation process and improving installation efficiency.

[0045] The two ends of the mounting portion 21 arranged along the central axis are also provided with protrusions 4 respectively, and the side walls of the protrusions 4 abut against the mounting hole 3;

[0046] The raised portion 4 includes a first unit 41 and a second unit 42. The first unit 41 is arranged along the first direction, and the second unit 42 is arranged along the central axis direction of the positioning portion 2. The first direction and the central axis direction are arranged perpendicular to each other. The first unit 41 is arranged in an arc shape, and the second unit 42 is arranged in a rectangular shape.

[0047] The mounting portion 21 is integrally connected with the positioning portion 2. The mounting portion 21 is in the shape of a cross column and is arranged on the positioning portion 2. When the positioning member is matched with the slide bed, the side of the positioning member 2 connected with the mounting portion 21 abuts against the surface of the slide bed, and part of the mounting portion 21 is placed in the mounting hole 3. The cross column shape design can provide a larger contact area, making the connection between the positioning member and the slide bed more firm and stable. This can ensure that the turnout will not shake or loosen during use, improve the safety and reliability of the railway turnout, evenly distribute the fixing force on the surface of the slide bed, avoid local excessive pressure, and reduce the risk of deformation or damage to the slide bed. Compared with designs of other shapes, the cross-shaped mounting portion 21 can more effectively utilize space while ensuring stability, avoiding unnecessary waste caused by excessive positioning members.

[0048] Specifically, the cross-shaped mounting portion 21 includes two groups of first units 41 and two groups of second units 42, wherein the first unit 41 is a protrusion in the length direction, and the first unit 41 is an arc-shaped column, and the second unit 42 is a protrusion in the width direction, and the second unit 42 is a regular rectangular protrusion, wherein the protrusion structure of the first unit 41 and the second unit 42 can provide additional support in different directions, increase the contact area between the positioning member and the slide bed plate, thereby improving the stability of the connection, making the turnout system more solid and reliable; the different shapes of the first unit 41 and the second unit 42 can cooperate with each other to provide more comprehensive support and stability. The arc-shaped column structure of the first unit 41 is more suitable for providing support in the length direction, while the regular rectangular protrusion of the second unit 42 is more suitable for providing stability in the width direction. The combination of the two can give full play to the advantages, thereby improving the firmness of the connection. Protrusions of different shapes can provide support at different angles and directions, disperse the fixing force, reduce local pressure concentration, and thereby reduce the deformation and damage risks of the slide bed plate. This multi-angle support design can improve the stability and durability of the connecting parts. The protrusions of different shapes can better adapt to the structural and shape changes of the fixed slide bed plate, so that the positioning buckle can play the best role in different situations. This design improves the adaptability and versatility of the positioning buckle and has a wider range of applications.

[0049] The positioning portion 2 is also provided with an arc surface 5 in the circumferential direction, and the arc surface 5 abuts against the inner wall of the mounting hole 3 . The side of the positioning portion 2 away from the mounting portion 21 is flush with the surface of the bottom plate 1 .

[0050] The positioning portion 2 includes an upper surface and a lower surface, the lower surface is connected to the mounting portion 21, and the arc surface 5 is arranged obliquely upward between the upper surface and the lower surface. The length dimension of the upper surface is greater than that of the lower surface. By setting the arc surface 5 obliquely upward and completely abutting against the inner wall of the mounting hole 3, it can be ensured that the positioning buckle is firmly fixed in the mounting hole 3, avoiding shaking or loosening, and improving the reliability of the connection. The design of the arc surface 5 can reduce the friction between the positioning buckle and the inner wall of the mounting hole 3, making the positioning buckle easier to install and remove, reducing the difficulty of operation, while also reducing wear and extending the service life. Setting the side of the positioning portion 2 away from the mounting portion 21 to be flush with the surface of the base plate 1 can make the pressure of the positioning buckle more evenly distributed on the surface of the base plate 1 when connected, avoiding damage to the sliding bed plate caused by excessive local pressure, and ensuring the overall stability.

[0051] The cross section of the mounting portion 21 gradually increases along a direction close to the central axis of the positioning portion 2 .

[0052] As the cross section increases, the structure of the mounting portion 21 becomes more solid and stable, can withstand greater tension and pressure, is not easily deformed or broken during use, and increases the bearing capacity of the positioning member. By designing a gradually increasing cross section, the force between the mounting portion 21 and the slide bed plate can be more evenly distributed, reducing local pressure concentration, reducing the pressure on the slide bed plate, and extending the service life.

[0053] The railway turnout slide bed positioning adjustment member further includes an adsorption member 6 and a first adjustment member 7, wherein the first adjustment member 7 is connected to the adsorption member 6, and the first adjustment member 7 is used to control the extension and retraction of the adsorption member 6, the positioning member is provided with a through hole 8, the adsorption member 6 is connected to the inner wall of the through hole 8, the adsorption member 6 extends out of the through hole 8 along the second direction, and the adsorption member 6 is attached to the surface of the mounting portion 21;

[0054] The adsorption member 6 includes a fixed portion 61, a telescopic portion 62 and an adsorption portion 63. The fixed portion 61 is connected to the inner wall of the through hole 8. The fixed portion 61 is hollow. One end of the telescopic portion 62 is connected to the adsorption portion 63. The other end of the telescopic portion 62 is connected to the first adjusting member 7. The telescopic portion 62 and the adsorption portion 63 are both arranged in the fixed portion 61. The first adjusting member 7 is used to adjust the telescopic portion 62. When the adsorption portion 63 protrudes from the opening of the through hole 8, the adsorption portion 63 abuts against the surface of the mounting portion 21.

[0055] The adsorption member 6 also includes a first magnetic portion 64 and a second magnetic portion 65. The first magnetic portion 64 is arranged at an end of the adsorption portion 63 away from the telescopic portion 62, and the second magnetic portion 65 is arranged on the telescopic portion 62. The first magnetic portion 64 and the second magnetic portion 65 attract each other, so that the adsorption portion 63 fits the telescopic portion 62.

[0056] First, the positioning member is provided with a through hole 8, the adsorption member 6 is connected to the inner wall of the through hole 8, the adsorption member 6 extends out of the through hole 8 along the second direction, the side of the adsorption member 6 close to the mounting portion 21 is in contact with the surface of the mounting portion 21, and the side away from the mounting portion 21 is in contact with the lower surface of the slide bed plate. This design realizes the contact of the adsorption member 6 with the surface of the mounting portion 21 and the lower surface of the slide bed plate through the connection between the through hole 8 and the adsorption member 6, thereby ensuring a tight connection between the positioning member and the slide bed plate.

[0057] Secondly, the adsorption member 6 includes a fixing portion 61 , a telescopic portion 62 and an adsorption portion 63 . The fixing portion 61 is connected to the inner wall of the through hole 8, and the fixing portion 61 is hollow; one end of the telescopic portion 62 is connected to the adsorption portion 63, and the other end is connected to the first adjusting member 7. The telescopic portion 62 and the adsorption portion 63 are both arranged in the fixing portion 61, and the end of the adsorption portion 63 is provided with a first adsorption hole and a second adsorption hole. When it is in the unextended state, the first adsorption hole is arranged close to one side of the telescopic portion 62, and the second adsorption hole is arranged away from one side of the telescopic portion 62. In the actual working state, the positioning member is installed on the slide bed plate, and the operator twists the first adjusting member 7 to make the telescopic portion 62 extend and retract. When the adsorption portion 63 protrudes out of the opening of the through hole 8, the adsorption portion 63 abuts against the surface of the mounting portion 21 by its own elastic force, and sucks out the gas inside the adsorption portion 63. Under the joint action of the first adsorption hole and the second adsorption hole, a pressure difference is formed, so that after the adsorption portion 63 extends out of the through hole 8 in the second direction, the side of the adsorption portion 63 close to the mounting portion 21 is in contact with the surface of the mounting portion 21, and the side away from the mounting portion 21 is in contact with the lower surface of the slide bed plate. Such a design achieves precise fitting of the adsorption portion 63 to the surface of the mounting portion 21 and the surface of the slide bed plate through the telescopic control of the telescopic portion 62, thereby ensuring a tight connection between the positioning member and the slide bed plate.

[0058] In the embodiment of the present application, the telescopic part 62 includes a threaded rod and a threaded nut. The first adjusting member 7 is an adjusting knob. The operator rotates the adjusting knob, and the knob is connected to the telescopic part 62. As the adjusting knob rotates, the rotational motion is transmitted to the threaded rod connected to the telescopic part 62. The threaded nut connected to the threaded rod is a thread that matches the threaded rod. When the threaded rod rotates, the threaded nut moves along the thread of the threaded rod. This relative motion will cause a relative displacement between the threaded rod and the threaded nut. Through the relative displacement of the threaded rod and the threaded nut, the telescopic part 62 moves forward or backward, thereby realizing the telescopic process of the telescopic part 62.

[0059] The telescopic part 62 will gradually expand and contract, and one end of the telescopic part 62 is connected to the adsorption part 63. When the adsorption part 63 protrudes out of the opening of the through hole 8, the adsorption part 63 uses its own elasticity to fit the surface of the mounting part 21 and suck out the gas inside the adsorption part 63. Under the action of the first adsorption hole and the second adsorption hole, the adsorption part 63 achieves precise fit to the surface of the mounting part 21 and the surface of the slide bed.

[0060] Finally, the adsorbent 6 also includes a first magnetic part 64, a second magnetic part 65 and a second adjusting part 9. The first magnetic part 64 is arranged at the end of the adsorbent part 63 away from the telescopic part 62, and the second magnetic part 65 is arranged on the telescopic part 62. When the adsorbent 6 needs to be pulled out from the through hole 8, the operator twists the second adjusting part 9. Under the control of the second adjusting part 9, the second adjusting part 9 is an adjusting knob. The operator rotates the adjusting knob, and the knob is connected to the second adjusting part 9. As the adjusting knob rotates, the second magnetic part 65 moves toward the direction close to the first magnetic part 64. The first magnetic part 64 and the second magnetic part 65 attract each other, so that the adsorbent part 63 fits the telescopic part 62, so as to facilitate the smooth removal of the adsorbent 6.

[0061] In summary, the design of the connection between the through hole 8 and the adsorption member 6 ensures that the adsorption member 6 fits the surface of the mounting portion 21, thereby achieving a tight connection between the positioning member and the slide bed plate. The setting of the fixed portion 61, the telescopic portion 62 and the adsorption portion 63 of the adsorption member 6, and the control of the telescopic portion 62 by the first adjustment member 7, together achieve the precise fit of the adsorption portion 63 to the surface of the mounting portion 21, thereby further strengthening the connection between the positioning member and the slide bed plate. In addition, the design of the first magnetic portion 64 and the second magnetic portion 65 enables the adsorption member 6 to be smoothly pulled out of the through hole 8 when it is necessary, while maintaining the reliably connected state of the adsorption member 6. In summary, this design effectively achieves the dual effects of tight connection and convenient operation between the adsorption member 6 and the mounting portion 21 and the slide bed plate, and provides reliable technical support for the stable connection between the positioning member and the slide bed plate.
