Description

Technical Field

[0001] The utility model belongs to the technical field of railway track switches, and in particular relates to a novel rail support sliding bed plate for a turnout assembly. Background Art

[0002] With the advancement of railway upgrades and renovations, railway yards have gradually completed the process of converting from wooden to concrete turnout ties (i.e., replacing existing wooden turnout ties with concrete). Due to limited station space, turnouts are typically connected end-to-end or arranged in a straight line. This results in insufficient distance between turnouts and between turnouts and sections, leading to interference between pads. The existing wooden sleeper turnouts use a simple, compact slide bed, but suffers from poor stability and lacks sufficient anti-rollover protection for the stock rails.

[0003] Currently, for a 9-turnout combination with 50kg / m rails (concrete sleepers), where the straight and curved rail ends are each connected to a set of switches, and the length of the straight line between the two rails is zero, conventional rail support and slide bed plates cannot be installed at the turnout junction due to limited space. Furthermore, the slide bed plates used in conventional concrete sleeper turnouts are structurally stable. To enhance the anti-roll capability of the stock rail, rail supports are placed at intervals outside the stock rail. This results in an overall larger size for the rail support and slide bed plates, leaving a smaller space for the turnout assembly. When used in a small space in a turnout assembly, interference between the rail support and slide bed plates may occur. To address this, the following improved technical solutions are proposed.

DETAILED DESCRIPTION

[0033] The following is a combination of the appended examples of the present invention Figure 1-7 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0034] (like Figure 1 A new type of rail support slide bed for a turnout assembly is shown in FIG. 1 , which has a concave-shaped conjoined bottom plate assembly 1 in which two bottom plates are connected. Figure 2 The present invention's integrated base plate 11 structure provides more stable support, and its shortened and optimized design allows for installation in confined spaces within turnout assemblies. This solves the technical problem of interference between the rail supports and slide beds, where conventional rail support and slide bed switches cannot be installed in the limited space between turnouts.

[0035] In the above embodiment, as a preferred embodiment of the present invention: the length of the one-piece base plate 11 is less than or equal to 570 mm; the width of the one-piece base plate 11 is less than or equal to 830 mm, which meets the installation requirements of small size and small space. It should be noted that: this embodiment is optimized in the length direction, from the original 590 mm to 570 mm. The small-sized one-piece base plate can flexibly adapt to various narrow spaces, such as urban subways, light rail systems and track laying in certain special environments, thereby improving the construction flexibility and adaptability of the track system. The small-sized base plate is lighter during installation, reducing the difficulty of lifting and transportation, thereby simplifying the construction process and improving construction efficiency. Smaller size means less material usage, which may reduce material costs.

[0036] (like Figure 3 (As shown in the figure), a rubber pad 3 is provided between the integrated base plate assembly 1 and the base rail 4. In the above embodiment, as a further improvement of the present invention, the rubber pad 3 is adapted to be mounted on the rail-supporting groove formed in the integrated base plate 11 to prevent slipping of the rubber pad 3, and the rubber pad 3 does not interfere with the installation of the base rail 4. In the present invention, the under-rail rubber pad 3 is adapted to be mounted on the rail-supporting groove to prevent slipping of the rubber pad 3.

[0037] (like Figure 1 As shown in FIG, the non-working side of the base rail 4 is prevented from tilting by two sets of rail support fasteners 2. The present invention adopts two sets of rail support fasteners 2, which can provide a more reliable anti-tilting capability of the base rail 4.

[0038] In the above embodiment, as a further improved embodiment of the present invention: (such as Figure 2 As shown) the one-piece bottom plate assembly 1 is composed of an integrally formed and concave one-piece bottom plate 11, two slide tables 12 axially symmetrically arranged on the upper end surface of the one-piece bottom plate 11, two axially symmetrical K-shaped iron seats 13, and two axially symmetrical blocking bars 14 (as shown Figure 1 The axisymmetric structure between the components of the one-piece floor assembly 1 of the present invention can reduce the number of parts, lower the manufacturing cost, and reduce the difficulty of installation.

[0039] In the above embodiment, as a further improved embodiment of the present invention: (such as Figure 3 As shown) the tongue of the slide bed 12 rigidly buckles the working side rail limb of the base rail 4; the non-working side of the base rail 4 is elastically buckled by the rail support fastener 2 (as shown Figure 1 shown).

[0040] In the above embodiment, as a further improved embodiment of the present invention: (such as Figure 3 As shown in the figure, the rail support fastener 2 includes a rail support 21, an adjusting wedge 22, a T-bolt 23, a spring bar 24, and a cap nut 25.

[0041] During use: place two rail supports 21 on the non-working sides of the basic rail 4, and make the side surfaces of the rail supports 21 contact the waist of the basic rail 4, so that the lower edge of the rail support 21 is supported by the upper end surface of the integrated bottom plate 11; after the rail supports 21 are placed in place, install the adjusting wedge 22, and select adjusting wedges 22 of different specifications according to different gaps; clamp the boss of the T-bolt 23 to the anti-rotation wall of the K-shaped iron seat 13, place the elastic bar 24 on the T-bolt 23, and install the cap nut 25 on the T-bolt 23; by adjusting the positions of the T-bolt 23 and the elastic bar 24, tighten the T-bolt 23, check the torque and complete the installation.

[0042] In the above embodiment, as a further improved embodiment of the present invention: (such as Figure 1 、 Figure 2 、 Figure 3 The switch tie bolt mounting holes 15 are located at the four corners of the integrated base plate 11. The positions of the switch tie bolt mounting holes 15 and the rail supports 21 are adaptively adjusted based on the dimensions of the integrated base plate 11, optimizing the dimensions of the integrated base plate 11 to meet the needs of small spaces.

[0043] In the above-mentioned embodiment, as a further improved embodiment of the present invention, (as shown in FIG4 ), the lower end surface of the rubber pad 3 is provided with a plurality of grooves 31 of the same shape and size. The groove 31 structure allows the rubber pad 3 to undergo flexure and shear deformation when subjected to pressure. This deformation can absorb and disperse energy from vehicle vibration and impact, thereby increasing the pad's elastic recovery rate. Under the action of dynamic wheel loads, the rubber pad 3 with the groove 31 structure has a lower dynamic stiffness and can produce a larger deformation, thereby more effectively providing elastic support for the track structure system and reducing vibration transmission to the roadbed and sleepers. The rubber pad 3 with the groove 31 on the lower end surface is easier to align and secure with the sleeper during installation, reducing the difficulty and time of installation. Because the groove 31 design helps to improve the stability and durability of the pad, it can extend the pad's service life, thereby reducing maintenance and replacement costs.

[0044] In the above embodiment, as a preferred embodiment of the present invention: the groove 31 is an isosceles trapezoidal structure or a circular arc structure; when it is an isosceles trapezoidal structure, a transition arc is formed at the corner of the groove 31. The groove design of the isosceles trapezoidal or circular arc structure can increase the flexural and shear deformation capabilities of the rubber pad, so that the pad can more effectively absorb and disperse vibration energy when under pressure, thereby improving the elastic recovery speed of the pad. The rubber pad with this structural design has a smaller dynamic stiffness under the action of the dynamic wheel load and can produce a larger deformation, providing better elastic support for the track structure system and reducing the impact of vibration on the roadbed and sleepers. The smooth transition of the arc shape can reduce the risk of cracks on the rubber pad during production and use, and improve the product yield and quality stability.

[0045] In the above embodiment, as a preferred embodiment of the present invention: the grooves 31 are an even number of 8. The eight grooves are symmetrically distributed in an even number, which helps to achieve mechanical balance and reduce vibration and stress concentration caused by asymmetry; this symmetrical design can enable the rubber pad to more evenly disperse and absorb vibration energy when under pressure, thereby improving vibration reduction and buffering effects. The design of an even number of grooves 31 may be more conducive to the uniform dispersion of stress and reduce material fatigue and damage caused by stress concentration, which helps to improve the structural stability and durability of the pad. The even number design of eight grooves 31 conforms to a certain standardized or modular design concept, making the installation and maintenance of the pad more convenient and quick. The standardized design also helps to reduce production costs and improve production efficiency.

[0046] The working principle of this utility model is: (as Figure 3When assembling (as shown), place the conjoined base plate assembly 1 in the specified position as required, place two modified rail under-rail rubber pads 3 on the left and right rail bearing grooves of the conjoined base plate 11 respectively, assemble the basic rail 4 and rigidly buckle the working side rail limbs of the basic rail 4 through the pressing tongues of the two slide platforms 12; the rail support assembly 2 elastically buckles the non-working side of the basic rail 4; place two rail supports 21 on the non-working side of the basic rail 4 as required, and the side surfaces of the rail support 21 are in contact with the waist of the basic rail 4 After the rail support 21 is in place, install the adjusting wedge 22. Select adjusting wedges 22 of different specifications according to different gaps. Clamp the boss of the T-bolt 23 to the anti-rotation wall of the K-shaped iron seat 13. Place the spring bar 24 on the T-bolt 23. Install the cap nut 25 on the T-bolt 23. After adjusting the position of the T-bolt 23 and the spring bar 24, tighten the T-bolt 23. Check the torque to complete the installation.

[0047] From the above description, it can be found that the structure of the utility model is stable, and the buckling pressure and supporting force of the basic rail 4 meet the needs of driving. The size optimization design of the connected bottom plate 11 makes it adaptable to a smaller installation space, which well solves the problems of small space and insufficient supporting force of concrete combined turnout.

[0048] Furthermore, the present invention can be used not only for small space rail support sliding bed (such as Figure 3 As shown in Figure 2), the design principle can also be applied to ordinary slide bed plates (such as Figure 5 As shown), elastic clip type ordinary slide bed plate (as Figure 6 As shown), elastic clip rail support sliding bed plate (as shown Figure 7 shown) and other situations.

[0049] In summary, the present invention is aimed at a 50kg / m rail 9-single-opening turnout combination (concrete turnout sleepers), that is, the straight and curved ends of the turnout are respectively connected to a group of turnsouts, and the length of the clamped straight line is zero. It solves the technical problem that the space at the connection between the turnsouts is small, the conventional rail support and sliding bed switch cannot be arranged, and interference between the rail support and sliding bed will occur; it is adapted to the small space working conditions of the turnout combination, has a stable structure, effectively prevents the rubber pad under the rail from slipping, has low manufacturing cost, low installation difficulty, wide application range, and is suitable for promotion.
