Description

Technical Field

[0001] This utility model relates to the field of steel railway turnout technology, specifically a railway turnout slide plate. Background Technology

[0002] The turnout slide plate is an important component of railway turnout switches. Its main function is to support the switch rails and reduce their movement resistance, ensuring smooth switching. The friction between the slide plate and the switch rails is the biggest factor affecting the smoothness of switch rail operation. Excessive friction will affect the switch's operation of the switch rails. At the same time, frequent switching operations can easily lead to severe wear on the slide plate, and under adverse conditions, may cause the slide plate to come loose.

[0003] Currently, the main ways to reduce switch rail resistance are: (1) applying lubricating oil to the bottom of the rail and the slide plate. After the slide plate is coated with oil, the fine sand and gravel driven by the train wind will stick to its surface, affecting the rail conversion; (2) setting rollers on one side of the slide plate, such as the roller slide plate disclosed in the utility model patent with announcement number CN203393523U. The slide plate of this structure has high requirements for the pad. The entire roller slide plate includes roller frame, roller assembly, eccentric roller, roller adjustment device, etc. The overall structure design is relatively complex and the manufacturing cost is high; (3) setting a pad on the slide plate to reduce the friction coefficient between the bottom of the switch rail and the slide plate, such as a slide plate disclosed in announcement number CN 218436406 U. By setting a pad made of polytetrafluoroethylene on the slide plate, since polytetrafluoroethylene has low hardness, it is easy to wear under the high load conditions of railway, resulting in low durability and increased maintenance costs. Utility Model Content

[0004] This utility model addresses the problems and defects existing in the above-mentioned background technology by providing a flexible railway turnout slide plate.

[0005] To achieve the above objectives, this utility model provides a railway turnout slide plate, including a base plate and a slide plate. One end of the base plate has a metal seat for fixing the main rail. The slide plate is located at the other end of the base plate, situated on one side. A ball bearing plate is located on the other side of the base plate, and the ball bearing plate has universal balls. The top of the universal balls is higher than the top surface of the slide plate. In use, the bottom of the switch rail contacts the universal balls, allowing the switch rail to slide on the balls, reducing switching resistance and ensuring flexible switching.

[0006] Furthermore, the ball bearing plate has a fixing part and a mounting part for mounting the universal ball bearings. The fixing part is located on both sides of the mounting part, and the height of the mounting part is higher than that of the fixing part. This structure facilitates the installation of the ball bearing plate with the pad and also prevents the bolts connecting the ball bearing plate and the pad from affecting the swing of the switch rail. The structural design is ingenious.

[0007] Furthermore, a fixing hole penetrating its upper and lower surfaces is provided on the fixing part, and the ball plate is mounted on the pad by fixing bolts installed in the fixing hole. This connection method facilitates the connection between the ball plate and the pad.

[0008] Furthermore, the fixing hole is an oblong hole. The design of the oblong hole allows for rotational installation according to the turnout model, making it convenient to use.

[0009] Furthermore, a mounting groove of the same length as the ball bearing plate is provided on the bottom surface of the fixing part, and the mounting groove corresponds to the fixing hole.

[0010] Furthermore, the pad is provided with a mounting platform that matches the mounting groove. The mounting platform has several spaced threaded holes that engage with the fixing bolts in the fixing holes to lock and fix the ball bearing plate. The cooperation between the mounting groove and the mounting platform facilitates the installation of the ball bearing plate while ensuring its installation accuracy. During processing, only the machining accuracy of the mating surfaces of the mounting platform and the mounting groove needs to be ensured, which is beneficial for processing and reduces processing costs.

[0011] Furthermore, two mounting holes are provided on the mounting part for mounting universal ball bearings.

[0012] Furthermore, the mounting hole is a countersunk hole, with a larger upper hole that is a spherical hole adapted to the ball bearing cage of the universal ball, and a smaller lower hole that is a cylindrical hole. This design of the mounting hole facilitates the installation of the universal ball bearing and reduces assembly difficulty.

[0013] Furthermore, an elongated hole penetrating the upper and lower surfaces of the pad is provided at the location corresponding to the mounting hole.

[0014] Furthermore, a fixing screw is provided at the bottom of the ball bearing holder. The universal ball bearing located in the mounting hole is locked by the fixing screw and the locking nut. The width of the locking nut is smaller than the width of the elongated hole. The elongated hole is designed to prevent the screw at the bottom of the universal ball bearing from interfering with the pad, ensuring smooth swing of the switch rail.

[0015] Compared with the prior art, the present invention has the following technical effects:

[0016] The slide plate of this utility model has a simple overall structure and reasonable design. By contacting the pointed rail with the universal ball bearings, the pointed rail slides on the ball bearings, reducing the switching resistance and ensuring the flexibility of switching. The ball bearing plate is installed on the pad plate with bolts, which is convenient for installation and reduces the assembly difficulty. Moreover, the installation groove is set on the bottom surface of the ball bearing plate and the installation platform is set on the pad plate. The combination of the two not only facilitates the assembly, but also reduces the processing difficulty of the ball bearing plate and the pad plate. During processing, only the machining accuracy requirements of the mounting surface of the mounting groove and the mounting platform are required, resulting in low processing cost.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] Example: See Figure 1 This utility model provides a railway turnout slide plate, including a base plate 1 and a slide plate 7. The top surface of the base plate has a slope of 1:40. A metal seat 5 for fixing the main rail is provided at the middle of one end of the base plate 1. Specifically, the metal seat 5 is welded to the higher end of the base plate 1. The slide plate 7 is located at the other end of the base plate 1. The metal seat 5 facilitates fixing the main rail with fasteners. An elastic clamp is provided inside the slide plate 7 to clamp and fix the main rail. See also... Figure 2 The slide plate 7 is located on one side of the pad 1, and the other side of the pad 1 is provided with a ball bearing plate 2. That is to say, the ball bearing plate 2 and the slide plate 7 are arranged parallel to each other along the transverse direction of the pad 1. The ball bearing plate 2 is provided with universal balls 5, and the top of the universal balls 5 is higher than the top surface of the slide plate 7. It can be understood that the top of the universal balls 5 protrudes from the top surface of the slide plate 7. In use, the bottom of the switch rail contacts the universal balls 5, causing the switch rail to slide on the balls. This converts the sliding friction between the switch rail and the slide plate into rolling friction, reducing the switching resistance of the switch rail and ensuring the flexibility of switching.

[0024] like Figure 2 and 3 As shown, in this embodiment, the ball bearing plate 2 has a fixing part 201 and a mounting part 202 for mounting the universal ball bearing 5. The fixing part 201 is located on both sides of the mounting part 202, and the height of the mounting part 202 is higher than that of the fixing part 201. It can be understood that the cross-section of the ball bearing plate 2 is convex. A fixing hole 13 is provided on the fixing part 201, penetrating its upper and lower surfaces. The ball bearing plate 2 is mounted on the pad 1 by fixing bolts 3 installed in the fixing holes 13. For details, see [link to documentation]. Figure 3 The ball bearing plate 2 is mounted on the base plate 1 by fixing bolts 3 and flat washers 4. The fixing hole 13 is an oblong hole, which can be rotated to install according to the model of the turnout, making it convenient to use.

[0025] A mounting groove 8, the same length as the ball plate 2, is provided on the bottom surface of the fixing part 201. The mounting groove 8 corresponds to the fixing hole 13. During machining, the roughness of the bottom of the mounting groove 8 does not exceed 6.3. A mounting platform 9, adapted to the mounting groove 8, is provided on the pad 1. The mounting platform 9 protrudes from the top surface of the pad 1 and has several spaced threaded holes 10 that cooperate with the fixing bolts 3 in the fixing holes 13 to lock and fix the ball plate 2. The cooperation between the mounting groove 8 and the mounting platform 9 facilitates the installation of the ball plate 2 while ensuring its installation accuracy. During machining, only the machining accuracy of the mating surfaces of the mounting platform 9 and the mounting groove 8 needs to be ensured, which is beneficial for machining and reduces machining costs.

[0026] The universal ball bearing 5 in this embodiment is a purchased component, using Alwayse universal balls. Its structure is not shown in the diagram, but it generally consists of a ball bearing cage, a hemispherical cup shell, a large support ball, and multiple smaller support balls housed within the cup shell. The ball bearing cage is fastened or riveted to the top of the cup shell. The top of the support ball has an opening, through which the upper part of the support ball protrudes from the ball bearing cage. Each ball in this universal ball bearing 5 is pre-lubricated during production to reduce maintenance frequency. Its structure is not specifically limited here; it only needs to enable omnidirectional rotation, thereby reducing the resistance of the switch rail transition.

[0027] See Figure 2 Two mounting holes 12 are provided on the mounting section 202 for mounting the universal ball bearings 5. In this embodiment, the mounting holes 12 are countersunk holes, with a larger upper hole that is a spherical hole adapted to the ball bearing cage of the universal ball bearings 5, and a smaller lower hole that is a cylindrical hole. A long slot 11 is provided on the pad 1 corresponding to the mounting holes 12, penetrating its upper and lower surfaces. A fixing screw is provided at the bottom of the ball bearing cage, and the universal ball bearings 5 ​​located in the mounting holes 12 are locked by the fixing screw and the locking nut. The width of the locking nut is smaller than the width of the long slot 11. The long slot 11 is designed to prevent the screw at the bottom of the universal ball bearings 5 ​​from interfering with the pad 1, ensuring smooth swing of the switch rail.

[0028] In an embodiment of this utility model not shown in the figure, the mounting hole 12 is a countersunk hole with a larger upper hole and a smaller lower hole. Both the upper hole and the lower hole are cylindrical holes. In this case, the universal ball bearing 5 and the mounting hole 12 are nested to ensure the stability of the universal ball bearing 5 within the mounting hole 12.

[0029] This invention features universal ball bearings mounted on a base plate, with the pointed rail contacting the ball bearings to reduce switching resistance and ensure flexible switching. The universal ball bearings are mounted on the base plate via ball bearing plates, resulting in a simple, rationally designed, and easy-to-manufacture structure. Mounting grooves are provided on the ball bearing plates, and mounting platforms that fit these grooves are provided on the base plate, reducing the overall machining difficulty and cost of the slide plate.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
