Description

Technical Field

[0001] This utility model relates to the field of railway engineering technology, and in particular to a railway crossing curve gauge adjustment device. Background Technology

[0002] In railway systems, the curved sections of the track experience changes in gauge due to the centrifugal force generated by trains, causing the rails to shift outwards. This shift not only affects train stability but can also threaten operational safety. This is particularly true at level crossings where the concrete ballast track outside the rails is structurally unique. Traditional gauge maintenance methods, such as installing gauge tie rods and rail braces, are often difficult to implement. Gauge tie rods are prone to causing wear on the rail sides and sleeper surfaces, failing to provide long-term effective gauge stability, while rail braces cannot meet the requirements for adjusting the gauge to the standard value. Furthermore, these traditional methods typically require significant maintenance work and manpower, resulting in high maintenance costs. Therefore, there is an urgent need for a new solution that can effectively maintain gauge stability over the long term while reducing maintenance costs. Utility Model Content

[0003] The purpose of this invention is to provide a railway crossing curve gauge adjustment device that can effectively maintain track gauge stability over a long period of time while reducing maintenance costs.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: This railway crossing curve gauge adjustment device includes a screw rod arranged laterally between the concrete monolithic track bed and the rail. One end of the screw rod is provided with a shim, and the other end is inserted into an iron block. A flat plate washer, a spring washer, and a nut assembly are arranged sequentially between the iron block and the shim rod.

[0005] A more specific technical solution than the above-mentioned technical solution may be that the nut assembly includes at least two nuts.

[0006] Furthermore, the iron block is provided with positioning holes.

[0007] Furthermore, the other end of the screw is inserted into the positioning hole.

[0008] Furthermore, the positioning hole is a blind hole.

[0009] Furthermore, the shim abuts against the web of the rail, and the iron block abuts against the inner wall of the monolithic concrete track bed.

[0010] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0011] This invention makes full use of the gap between the integral concrete track bed and the rails, and installs a gauge adjustment device in these gaps to effectively resist the centrifugal force generated during train operation. This can effectively maintain the track gauge stability for a long time and improve the smoothness and safety of train operation. At the same time, this invention makes full use of the existing structural features of the crossing, eliminating the need for large-scale modification or closure of the crossing for maintenance, thereby greatly reducing installation and maintenance costs and having high economic and social benefits. Attached Figure Description

[0012] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0013] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model; however, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0014] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0016] like Figure 1 The railway crossing curve gauge adjustment device shown includes a screw rod 3 that is transversely arranged between the concrete monolithic track bed 1 and the rail 2. One end of the screw rod 3 is provided with a shim 4, and the other end is inserted into an iron block 5. A flat plate shim 6, a spring shim 7, a first nut 8 and a second nut 9 are arranged sequentially between the iron block 5 and the shim 4.

[0017] The iron block 5 has a positioning hole, and the other end of the screw 3 is inserted into the positioning hole.

[0018] Preferably, the positioning hole is a blind hole to prevent the screw 3 from passing through the iron block 5 and abrading the concrete monolithic track bed 1.

[0019] In practical use, this utility model is placed between the concrete monolithic track bed 1 and the steel rail 2. The second nut 9 is tightened towards the side of the shim 4, and the first nut 8 is tightened towards the side of the concrete monolithic track bed 1, so that the shim 4 abuts against the rail web of the steel rail 2, and the iron block 5 abuts against the inner wall of the concrete monolithic track bed 1. Then, the second nut 9 and the screw rod 3 are locked together by electric welding. After long-term use, even if the distance between the concrete monolithic track bed 1 and the steel rail 2 changes, it is only necessary to adjust the position of the first nut 8 on the screw rod 3 to maintain the function of this utility model and maintain track gauge stability.

[0020] In practical applications, since the distance between the integral concrete track bed 1 and the steel rail 2 gradually increases from top to bottom, the iron block 5 is set as a trapezoid with a smaller top and a larger bottom. One side of the iron block 5 is attached to the inner wall of the integral concrete track bed 1 so that the present invention has sufficient support and prevents movement.

[0021] The flat plate shim 6 and the spring shim 7 serve to prevent the device from loosening, and the second nut 9 can increase the support strength of the shim 4 to the rail 2.

[0022] This invention makes full use of the gap between the integral concrete track bed and the rails, and installs a gauge adjustment device in these gaps to effectively resist the centrifugal force generated during train operation. This can effectively maintain the track gauge stability for a long time and improve the smoothness and safety of train operation. At the same time, this invention makes full use of the existing structural features of the crossing, eliminating the need for large-scale modification or closure of the crossing for maintenance, thereby greatly reducing installation and maintenance costs and having high economic and social benefits.

[0023] After practical application, the gauge variation rate of the level crossing with this invention installed was significantly reduced compared with that without the invention. This invention demonstrated good durability and reliability, and can work stably for a long time, achieving remarkable results in maintaining gauge stability.
