Description

Technical Field

[0001] This utility model relates to the technical field of railway turnout conversion adjustment plates, and more specifically to railway turnout conversion roller adjustment plates. Background Technology

[0002] Railway turnout switching is a core component of railway track switching. To reduce friction between the switch rail and the stock rail and minimize rail wear, the industry commonly uses rollers installed on the turnout slide plate. This converts the sliding friction of the switch rail into rolling friction, thereby improving the smoothness of turnout switching and extending the service life of the rails. The installation accuracy of these rollers directly affects the switching effect. Precise adjustments are required for the height difference between the roller and the slide plate, the gap between the roller and the switch rail, and the installation angle of the roller. Therefore, the roller adjustment component is a key auxiliary component in the turnout switching system.

[0003] Currently, the industry lacks dedicated roller adjustment instruments. Adjustments are often made by placing multiple layers of thin adjusting shims between the slide plate and the roller. This method is not only cumbersome and time-consuming, but the overlapping shims can also loosen, leading to height deviations. Furthermore, there is no clear calibration standard for the 45° installation angle of the rollers; it relies entirely on the operator's experience, making it difficult to ensure a consistent angle. This can result in uneven contact between the rollers and the switch rails, exacerbating localized friction and wear. In addition, the frequent disassembly of tools to loosen the roller screws further reduces work efficiency.

[0004] Therefore, there is an urgent need to design a railway turnout conversion roller adjustment plate that can easily achieve precise calibration of roller height, clearance and angle, replace the traditional shim adjustment plate method, and improve the standardization of adjustment and work efficiency. Utility Model Content

[0005] This utility model provides a railway turnout conversion roller adjustment plate to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a railway turnout conversion roller adjustment plate, comprising: an adjustment plate, wherein a leveling device is provided on the front side of the adjustment plate; a limiting plate is provided at an angle on the side of the adjustment plate; and a first adjustment platform, a second adjustment platform, and a third adjustment platform of different thicknesses are provided on the back side of the adjustment plate.

[0007] Preferably, the leveler is two bubble levels, one horizontal and one vertical.

[0008] Preferably, the adjustment plate is also provided with an adjustment port, through which the screws on the railway turnout conversion roller are adjusted.

[0009] Preferably, the thickness of the first adjustment platform is 9mm; the thickness of the second adjustment platform is 6mm; and the thickness of the third adjustment platform is 4mm.

[0010] Preferably, the tilt angle between the limiting plate and the adjusting plate is 135°.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] Precise angle calibration solves the judgment problem: The leveler 2 uses a horizontal and vertical double bubble level 5, which can intuitively observe the position of the bubble to judge the horizontal and vertical flatness of the roller. Combined with the 135° fixed angle limit plate 3, it replaces the traditional experience-based judgment method, realizes the standardized calibration of the roller installation angle, avoids the problem of uneven contact caused by angle deviation, and reduces the local friction loss of the switch rail.

[0013] Simplified height adjustment and improved operating efficiency: The first adjustment platform 6, the second adjustment platform 7, and the third adjustment platform 8 with different thicknesses on the back can be used directly to adapt to the height difference between the slide plate and the rollers, which greatly improves work efficiency.

[0014] Integrated adjustment function optimizes ease of operation: The adjustment port 4 on the adjustment plate 1 allows tools such as wrenches to be directly inserted to tighten the roller screws, eliminating the need to frequently remove the adjustment plate for operation and further simplifying the operation process.

[0015] Standardized adjustments enhance operational stability: The overall structure combines mechanical positioning (limit plate), visual calibration (bubble level), and adaptive height adjustment (adjustment platform) to avoid human error, ensuring consistent adjustment results for different operators. This improves the stability of turnout switching, reduces the risk of equipment failure due to improper roller adjustment, and extends the service life of turnouts and rails.

[0025] Please see the appendix Figure 1-2 The present invention discloses a railway turnout conversion roller adjustment plate, comprising: an adjustment plate 1, a leveling device 2 on the front of the adjustment plate 1; a limiting plate 3 inclined on the side of the adjustment plate 1; and a first adjustment platform 6, a second adjustment platform 7 and a third adjustment platform 8 of different thicknesses on the back of the adjustment plate 1.

[0026] Specifically, the adjustment plate 1 is 195mm long, 90mm wide, and 9mm thick, and has high strength and corrosion resistance, making it suitable for railway outdoor operation environments; the first adjustment platform 6, the second adjustment platform 7, and the third adjustment platform 8 are all integrally formed with the adjustment plate 1.

[0027] To further optimize the above technical solution, the leveler 2 consists of two bubble levels 5, one horizontal and one vertical.

[0028] Specifically, the outer shell of the bubble level 5 is made of transparent acrylic material and filled with industrial alcohol; the two bubble levels 5 are perpendicular to each other, one is set horizontally along the length of the adjustment plate 1 and the other is set vertically along the width of the adjustment plate 1, both are sealed and installed inside the leveler 2, and the surface is printed with scale lines.

[0029] The bubble level 5 utilizes the fluidity of alcohol bubbles. When the adjustment plate 1 is horizontal, the bubble in the horizontally set bubble level 5 is located at the center mark; when the adjustment plate 1 is vertically level, the bubble in the vertically set bubble level 5 is located at the center mark, thereby determining the flatness of the roller.

[0030] After placing the adjustment plate 1, observe whether the horizontal bubble is centered. If it is offset, fine-tune the screw on the roller. Observe whether the vertical bubble is centered. If it is offset, fine-tune the screw on the roller until both bubbles are centered.

[0031] To further optimize the above technical solution, the adjustment plate 1 is also provided with an adjustment port 4, through which the screws on the railway turnout conversion roller are adjusted.

[0032] Specifically, the adjustment port 4 is a through hole formed by laser cutting of the adjustment plate 1 body, and the edges are polished smooth to avoid scratches. The size of the adjustment port 4 is adapted to the head of a commonly used wrench, allowing the wrench to be directly inserted and fitted with the roller screw, so that the screw can be tightened or loosened without disassembling the adjustment plate.

[0033] To further optimize the above technical solution, the thickness of the first adjustment platform 6 is 9mm; the thickness of the second adjustment platform 7 is 6mm; and the thickness of the third adjustment platform 8 is 4mm.

[0034] Specifically, the height difference of the adjustment platform can better adapt to the height difference between the main rail, the turnout slide plate, and the roller, making the roller adjustment plate leveling more accurate. The area of ​​the first adjustment platform 6 is half that of the adjustment plate 1, and the areas of the second and third adjustment platforms are one-quarter of that of the adjustment plate 1. The second adjustment position is adjacent to the limit plate 3.

[0035] To further optimize the above technical solution, the tilt angle between the limiting plate 3 and the adjusting plate 1 is 135°.

[0036] Specifically, the limiting plate 3 is used to tilt and insert into the gap between the base and the rail, better limiting the position of the adjusting plate 1. The limiting plate 3 is fixedly connected to the adjusting plate 1 by locking components or welding. The standard installation angle of the turnout roller is 45°. The 135° angle between the limiting plate 3 and the adjusting plate 1 can complement the 45° angle of the roller, ensuring that the roller installation angle meets the standard through physical limiting.

[0037] How to use

[0038] Place the adjusting plate 1 on the roller at the turnout slide plate, and insert the limiting plate 3 at an angle into the gap between the base and the rail to ensure that the adjusting plate 1 and the roller are in close contact, thus initially fixing the position of the adjusting plate 1 and the roller.

[0039] Observe the two bubble levels 5 on the front of the adjustment plate 1. If the bubbles are offset in the horizontal or vertical direction, pass the wrench head through the adjustment port on the adjustment plate and align it with the screw on the roller to level it until both bubbles are at the center scale. At this time, the flatness and angle of the roller meet the standard.
