Description

Technical Field

[0001] The present invention relates to the technical field of rail transit maintenance. Specifically, it relates to a scale plate and a control method for quantitative control of the pre-pressure of a rail corrugation suppressor. This technology aims to solve the problem of inaccurate pre-pressure application during the installation of the rail corrugation suppressor and is applicable to precise mechanical adjustment and control during the installation of the rail corrugation suppressor.

[0002] The rail corrugation suppressor is a key mechanical device whose function is to inhibit the generation of wavy wear on the rail surface, thereby improving the service life of the rail and related components. During the installation of the suppressor, the magnitude of the pre-pressure directly affects its fixing effect and vibration damping performance. If the applied pre-pressure is too large, it may cause structural deformation, and if it is too small, the effect of the suppressor will be reduced. Therefore, how to accurately control the applied pre-pressure has become an important technical problem.

[0003] The present invention proposes a scale plate device with simple design, convenient operation and high control precision. By cooperating with the rail and the corrugation suppressor, it can achieve quantitative control of the pre-pressure. At the same time, combined with the control method, the invention is suitable for scenarios of high-precision pressure control and has high application value and promotion potential. Background Art

[0004] Rail corrugation is a phenomenon of periodic wavy wear on the rail surface and is one of the common technical problems in rail transit. The formation of corrugation will cause large vibrations and noises during train operation, and at the same time, it will intensify the wear between the rail and the wheels. This will not only shorten the service life of the rail and the wheels, but also significantly affect the safety and comfort of train operation. Therefore, the effective suppression of rail corrugation has become an important task in track system maintenance.

[0005] The rail corrugation suppressor is a device designed for the corrugation problem. By applying a certain pre-pressure, it closely adheres to the rail, thereby changing the dynamic characteristics of corrugation formation and achieving the effect of suppressing the development of corrugation. The working performance of the suppressor largely depends on the pre-pressure applied during installation. If the pre-pressure is applied too large, it will cause structural deformation of the rail or the suppressor body, thereby reducing the reliability and service life of the equipment; if the pre-pressure is too small, it may lead to poor contact between the suppressor and the rail and fail to fully exert its suppression effect. Therefore, during the installation of the rail corrugation suppressor, applying an appropriate and accurate pre-pressure is the key to achieving the best suppression effect.

[0006] Currently, for the application of the pre-pressure of the rail corrugation suppressor, most rely on the following methods:

[0007] 1. Empirical control method: Operators judge whether the pre-pressure meets the requirements based on construction experience through visual inspection or simple measurement. This method highly depends on the experience of operators and it is difficult to ensure the consistency and accuracy of the applied pressure.

[0008] 2. Complex instrument assistance method: In some scenarios, complex measuring instruments (such as sensors and pressure gauges) are used for auxiliary control. Although these methods can provide high precision, the high cost of instrument equipment and operation complexity limit their wide application on-site.

[0009] 3. Simple tool force application method: Simple tools (such as wrenches or clamps) are used to apply pre-pressure. Although the operation is relatively simple, due to the lack of quantitative standard tools, it is difficult to ensure the accuracy and repeatability of the pressure.

[0010] These methods have deficiencies such as inconvenient operation, low control precision, and high equipment cost in actual use. Therefore, there is an urgent need for a tool or device that can quickly, accurately, economically and efficiently achieve quantitative control of pre-pressure at the construction site.

[0011] In view of the above problems, the present invention proposes a scale plate and control method for quantitative control of pre-pressure of a rail corrugation suppressor with simple design, convenient operation and high precision. Through the special geometric structure design, the scale plate can directly feedback the application state of the pre-pressure, so as to quickly judge whether it meets the design requirements.

[0012] Compared with the prior art, the advantages of the present invention are reflected in the following aspects:

[0013] 1. Reasonable structure design:

[0014] The scale plate consists of an upper working surface, a lower working surface, a vertical positioning surface and a handheld end. The overall structure is compact, which is convenient for operation and carrying.

[0015] 2. Simple operation:

[0016] Intuitively judge through the fitting state of the upper and lower working surfaces of the scale plate with the rail and the suppressor, and the control of the pre-pressure can be completed without additional complex equipment.

[0017] 3. High control precision:

[0018] The vertical distance between the upper working surface and the lower working surface is designed as a fixed value, which corresponds to the optimal pre-pressure required by the suppressor, ensuring the consistency and reliability of the pressure during the installation process.

[0019] 4. Wide application range:

[0020] In addition to being applicable to the installation of rail corrugation suppressors, the present invention can also be applied to other mechanical assembly occasions that require the application of a quantitative pre-pressure, such as industrial manufacturing and engineering construction fields.

[0021] Through the present invention, construction personnel can achieve precise control of the pre-pressure of rail corrugation suppressors at low cost and high efficiency, thereby significantly improving the construction quality and having broad prospects for popularization and application.

[0030] Technical Problem

[0031] During the installation process of rail corrugation suppressors, the pre-pressure is a key parameter determining the performance of the device.

[0076] The adjusting scale plate is mainly composed of the following parts:

[0077] a. Upper working surface: Used to detect whether it fits with the bottom surface of the rail after applying the pre-pressure, which is flat and smooth to ensure the detection accuracy.

[0078] b. Lower working surface: Used to fit with the upper surface of the extended part of the rail corrugation suppressor base to ensure the positioning accuracy.

[0083] b. Material selection: The scale plate is made of high-strength and wear-resistant materials (such as alloy steel or engineering plastics) to ensure that it does not deform during long-term use and meets the durability requirements of the construction environment.

[0084] Example 2: Usage method of the scale plate

[0085] The scale plate of the present invention realizes the quantitative control of the pre-pressure through the following steps:

[0086] 1. Initial preparation

[0087] a. Fix the rail corrugation suppressor on the rail, but do not fully apply the pre-pressure.

[0088] b. Take out the adjusting scale plate, check the upper and lower working surfaces and the surface state of the scale plate to ensure that it is clean and free of dirt and damage.

[0089] 2. Placing the scale plate

[0090] Fit the lower working surface of the scale plate to the upper surface of the extended part of the base of the rail corrugation suppressor, ensure the correct position, and press the vertical positioning surface tightly against the side of the rail to ensure the consistent installation direction.

[0091] 3. Applying pre-pressure

[0093] b. When the upper working surface of the scale plate is fully fitted to the bottom surface of the rail, it indicates that the pre-pressure has reached the design requirements.

[0094] 4. Removing the scale plate

[0095] a. Stop applying pressure, gently remove the scale plate, check the fitting state of the rail corrugation suppressor and the rail, and confirm the completion of the device installation.
