[0001] The present application relates to rail transportation technology, and in particular to a rail mounting seat and a switch. Background Art

[0002] The switch is a key equipment in the rail transit system, mainly used to realize the conversion of switches, thereby controlling the transfer of rail vehicles from one track to another.

[0003] Currently, a switch consists of a pad, stock rail, and point rail. The pad is fixed to the mounting surface, and the base of the stock rail is pressed onto the pad by spring clips and a rigid pressing plate on either side. During on-site installation, the fixed position of the pad and the rigid pressing plate securely fastened to the pad make it impossible to adjust the position of the stock rail, making on-site installation difficult. Furthermore, if the stock rail and point rail wear and tear during use, resulting in track gauge changes, the gauge cannot be adjusted, impacting normal operation. Summary of the Invention

[0004] The present application provides a track mounting seat and switch, which can adjust the installation position of the pad during the installation process to adjust the installation position of the base rail, reduce the installation difficulty, and can adjust the track gauge after wear.

[0015] a first fixing assembly, disposed on the upper surface of the pad;

[0016] a stock rail connected to the upper surface of the backing plate via the first fixing assembly;

[0017] a second fixing assembly, disposed on the upper surface of the pad;

[0018] a pointed rail connected to the upper surface of the backing plate via the second fixing assembly;

[0019] The base rail and the point rail are arranged at intervals along the extension direction of the base plate.

[0020] In some embodiments, the first fixing assembly includes:

[0021] A pressing platform is provided on the upper surface of the pad, one end of the pressing platform is provided with a limiting groove, and the working side rail bottom of the basic rail is embedded in the limiting groove;

However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted.

[0044] An embodiment of the present application provides a rail mounting base that can be used to install a common rail or to install a base rail and a point rail in a switch.

[0045] Reference Figure 1 The rail mounting base 100 includes a backing plate 110, a mounting sleeve 120, and a fastener 130. The backing plate 110 is provided with a mounting hole 1101. The mounting sleeve 120 is inserted into the mounting hole 1101 and has a connecting hole 1201, which is eccentrically positioned relative to the mounting hole 1101. The fastener 130 is inserted into the connecting hole 1201 to secure the backing plate 110.

[0046] The backing plate 110 is horizontally arranged, with its upper surface used for mounting the track and its lower surface for placement on a support such as a sleeper. The shape of the backing plate 110 can be customized based on the track installation requirements. For example, the backing plate 110 can be a horizontally arranged rectangular plate. The mounting holes 1101 can be blind holes or through holes, and can be located at the ends of the backing plate 110. Exemplarily, there are two mounting holes 1101, one at each end of the backing plate 110's extension direction.

[0047] The number of mounting sleeves 120 is the same as the number of mounting holes 1101. For example, there are two mounting sleeves 120, each inserted into one of the two mounting holes 1101. The connection holes 1201 on the mounting sleeve 120 are parallel to the central axis of the mounting sleeve 120 and spaced apart by a predetermined distance. When the mounting sleeve 120 is inserted into the mounting hole 1101, the axis of the connection hole 1201 is parallel to the central axis of the mounting hole 1101 and spaced apart by a predetermined distance, thereby eccentrically positioning the connection hole 1201 relative to the mounting hole 1101.

[0048] The fastener 130 may be a bolt, which is screwed into the support body below the pad 110 by passing through the connection hole 1201 , and the head of the bolt can be used to press the pad 110 , thereby fixing the pad 110 on the support body.

[0049] The eccentric distance between the connection hole 1201 and the mounting sleeve 120 can be adjusted based on actual installation requirements. Multiple mounting sleeves 120 with different eccentric distances can be pre-set based on commonly used installation dimensions. During installation, the eccentric distance between the connection hole 1201 and the mounting hole 1101 can be adjusted by changing the installation direction of the mounting sleeve 120 or replacing the mounting sleeve 120 with a different eccentric distance. This allows the fixed position of the base plate 110 to be adjusted while maintaining the position of the fastener 130, thereby facilitating adjustment of the track gauge of the track mounted on the upper surface of the base plate 110.

[0050] Reference Figure 2 In some embodiments, the mounting hole 1101 is a strip-shaped hole, the cross-sectional shape of the mounting sleeve 120 is the same as the shape of the strip-shaped hole, and the axis of the connecting hole 1201 is spaced apart from the center of the strip-shaped hole.

[0051] When the cross-sectional shapes of the mounting hole 1101 and the mounting sleeve 120 are both bar-shaped holes, the outer contour of their cross-sections is composed of two straight line segments and two arc segments, the center of which is the midpoint of the line connecting the centers of the two arc segments. The center of the cross-sectional circle of the connecting hole 1201 can be located on the line connecting the centers of the circles, and there is a distance between it and the midpoint of the line connecting the centers of the circles, so that the connecting hole 1201 is eccentrically arranged relative to the mounting hole 1101.

[0052] During the installation process, the installation direction of the mounting sleeve 120 can be changed, and the eccentric position of the connecting hole 1201 relative to the mounting hole 1101 can be changed. The plane formed by the straight line segments on both sides of the strip hole can be used to locate the installation position of the mounting sleeve 120, and can also prevent the mounting sleeve 120 from rotating in the mounting hole 1101.

[0053] Of course, the cross-sectional shape of the mounting hole 1101 and the mounting sleeve 120 may also be an ellipse or other regular or irregular polygonal structures, which will not be described in detail in this embodiment.

[0054] In some embodiments, the mounting sleeve 120 is provided with a limiting member 121 , and the limiting member 121 abuts against the upper surface of the pad 110 .

[0055] The stopper 121 can be integrally formed on the top of the mounting sleeve 120. The stopper 121 can be a protrusion extending from the top of the mounting sleeve 120 away from the axis of the connection hole 1201. The protrusion can be annular or have another shape. After the mounting sleeve 120 is inserted into the mounting hole 1101, the stopper 121 can abut against the upper surface of the backing plate 110 to limit the installation position of the mounting sleeve 120 and prevent the mounting sleeve 120 from passing directly through the mounting hole 1101.

[0056] When the bolt is tightened, the head of the bolt is pressed against the upper surface of the limiting member 121 and the backing plate 110 is pressed against the limiting member 121 .

[0057] In some embodiments, the rail mounting base 100 further includes a gasket 140 disposed on the upper surface of the limiting member 121 , and the fastener 130 presses the gasket 140 against the limiting member 121 .

[0058] The shape of the gasket 140 is the same as the shape of the upper surface of the mounting sleeve 120. The gasket 140 can be made of elastic material or rigid material. The bolts are tightened and pressed on the upper surface of the gasket 140 to

[0059] Based on the above-mentioned track mounting base 100, an embodiment of the present application further provides a switch, including the track mounting base 100 in the above-mentioned embodiment, so as to facilitate adjustment of the track gauge of the switch.

[0060] Reference Figure 3 In some embodiments, the switch further includes: a stock rail 200, a switch rail 300, a first fixing assembly 400, and a second fixing assembly 500. The first fixing assembly 400 is disposed on the upper surface of the base plate 110, and the stock rail 200 is connected to the upper surface of the base plate 110 via the first fixing assembly 400. The second fixing assembly 500 is disposed on the upper surface of the base plate 110, and the switch rail 300 is connected to the upper surface of the base plate 110 via the second fixing assembly 500. The stock rail 200 and the switch rail 300 are spaced apart along the extension direction of the base plate 110.

[0061] During the installation process, the eccentric distance of the connecting hole 1201 relative to the mounting hole 1101 can be adjusted by replacing the mounting sleeve 120 or changing the installation direction of the mounting sleeve 120, thereby adjusting the fixing position of the fastener 130 on the pad 110, thereby achieving adjustment of the position of the basic rail 200 and the point rail 300, and also being able to adjust the track gauge after the basic rail 200 or the point rail 300 is worn and the track gauge changes.

[0062] In some embodiments, the first fixing assembly 400 includes a press plate 410, a first gauge block 420, and a first pressing member 430. The press plate 410 is disposed on the upper surface of the backing plate 110. One end of the press plate 410 defines a retaining groove 4101, into which the working side rail bottom of the stock rail 200 is embedded. The first gauge block 420 is pressed against the non-working side rail bottom of the stock rail 200. The first pressing member 430 is disposed on the backing plate 110 and is used to secure the first gauge block 420.

[0063] The side of the rail bottom portion of the stock rail 200 facing the point rail 300 is the working side, and the other side is the non-working side.

[0064] The press platform 410 can be fixed to the base plate 110 by fasteners 130 such as bolts. A limiting groove 4101 is opened at one end of the press platform 410 facing the basic rail 200. The working side rail bottom of the basic rail 200 is embedded in the limiting groove 4101, and a gap of 1 mm can be set between the inner wall of the limiting groove 4101 and the upper surface of the working side rail bottom of the basic rail 200.

[0065] Since the position of the press platform 410 is fixed relative to the base plate 110, the position of the basic rail 200 is also fixed relative to the press platform 410. The position of the basic rail 200 cannot be adjusted by adjusting the first track gauge or the press platform 410. Therefore, the installation position of the base plate 110 can be adjusted by replacing the installation sleeve 120 or changing the installation direction of the installation sleeve 120, thereby adjusting the installation position of the basic rail 200.

[0066] In some embodiments, the second fixing assembly 500 includes a second gauge block 510, a third gauge block 520, and a second pressing member 530. The second gauge block 510 is pressed onto the working side rail bottom of the switch rail 300, the third gauge block 520 is pressed onto the non-working rail bottom of the switch rail 300, and the second pressing member 530 is disposed on the pressing platform 410 to fix the second gauge block 510 and the third gauge block 520.

[0067] The side of the rail bottom portion of the point rail 300 facing the stock rail 200 is the working side, and the other side is the non-working side.

[0068] The installation position of the point rail 300 can be adjusted by replacing the second gauge block 510 and the third gauge block 520, and then adjusting the installation position of the basic rail 200 by adjusting the position of the pad 110. The relative positions of the basic rail 200 and the point rail 300 can be adjusted, thereby reducing the installation difficulty of the switch and facilitating installation construction.

[0069] The first pressing piece 430 and the second pressing piece 530 may both be spring clip fasteners, so as to facilitate the installation and replacement of the first gauge block 420 , the second gauge block 510 and the third gauge block 520 .

[0070] The embodiments of the present application are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only intended to help understand the method and core ideas of the present application. At the same time, changes or modifications made by those skilled in the art based on the ideas of the present application, the specific implementation methods, and the scope of application of the present application, all fall within the scope of protection of the present application. In summary, the contents of this specification should not be construed as limiting the present application.
