Description

Technical Field

[0001] This utility model relates to the field of rail bracing and padding technology, specifically to an integrated rail bracing padding assembly. Background Technology

[0002] In curved sections of rail lines, rail braces and bearing plates are required to effectively resist lateral forces on the rails. This prevents excessive lateral displacement of the rails when trains pass over curves, which could lead to rail overturning and gauge widening, thus ensuring rail stability. Traditional rail braces and bearing plates are not only bulky but also inconvenient to assemble and install with the rails. Therefore, there is an urgent need for an integrated rail brace and bearing plate assembly to solve these problems. Utility Model Content

[0003] To address the technical problems of traditional rail braces and pads being not only bulky but also inconvenient to assemble and install rails, this utility model provides an integrated rail brace and pad assembly. The pad and rail brace are integrally formed, with a simple structure that facilitates rail fixing. Furthermore, the limiting protrusions, limiting ribs, and rail brace all limit the position of the rail, thereby effectively preventing lateral displacement of the rail.

[0004] This utility model provides an integrated rail support pad assembly, including an integrally formed pad and a rail support with the rail support perpendicular to the pad. The pad is provided with a limiting protrusion strip, and the rail support is located to the side of the limiting protrusion strip. The rail support is provided with a fixing opening and a limiting rib plate, and the limiting rib plate is located on the side of the rail support away from the limiting protrusion strip. The rail is placed on the pad, and the rail is located between the limiting protrusion strip and the limiting rib plate and below the fixing opening.

[0005] Furthermore, the rail brace includes a cross plate and two side plates. The two side plates are fixedly mounted on a base plate and arranged symmetrically. The cross plate is fixedly connected between the two side plates, and there is a space between the cross plate and the base plate. Two fixing openings are provided and respectively located on the two side plates and corresponding to each other. Two limiting ribs are provided and respectively fixedly mounted between one side plate, the cross plate, and the base plate, and between the other side plate, the cross plate, and the base plate. The two limiting ribs are located above the two fixing openings. The space between the cross plate and the base plate allows the rail to pass through this space, ensuring that both ends of the rail bottom can pass through this space and then abut against the limiting protrusion and the limiting ribs, respectively. The limiting ribs further strengthen the connection between the base plate and the rail brace.

[0006] Furthermore, the pad has multiple first fixing holes and second fixing holes on both sides, and the limiting protrusion has multiple notches. Each first fixing hole is located directly below the notch, and each second fixing hole is on the same straight line as the connection between the limiting rib and the pad. Bolts pass through the notches and first fixing holes and are then fixed to the sleeper. The bolts fix one end of the rail to the rail support, and also fix the rail support and rail to the sleeper. Bolts pass through the second fixing holes and are then fixed to the sleeper. The bolts fix the other end of the rail to the rail support, and also fix the rail support and rail to the sleeper.

[0007] Furthermore, the pad is provided with third fixing holes on both sides, and multiple first fixing holes and second fixing holes are located between two third fixing holes. The track spike passes through the third fixing holes to fix the pad to the sleeper.

[0008] Furthermore, fixing sleeves are provided on both sides of the pad, with two fixing sleeves located outside the two third fixing holes. A fixing rod is fixedly installed in each fixing sleeve, with both ends of the fixing rod located outside the pad and having pin holes. The pin passes through the pin holes of the fixing rod and is fixed to the sleeper. The fixing rod further limits the position of the pad, thereby ensuring the stability of the rail and effectively preventing lateral displacement of the rail.

[0009] Furthermore, each of the limiting ribs is L-shaped, and each of the limiting ribs and the fixing opening is provided with an arc.

[0010] Furthermore, the width of the side plate gradually increases from the top to the bottom. This structural design of the side plate makes the rail brace and pad more stable, which in turn makes the rail brace more stable when supporting the rail.

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

[0012] In use, the integrated rail support pad assembly of this utility model has the pad fixed to the sleeper by rail spikes, and the rail placed on the pad (the side of the rail support is attached to the outer surface of the rail). The rail is located between the limiting protrusion and the limiting stiffener and below the fixing opening. That is, the two ends of the bottom of the rail abut against the limiting protrusion and the limiting stiffener respectively and are located below the fixing opening. The limiting protrusion, the limiting stiffener, and the rail support all limit the position of the rail, and the rail support and the end of the rail are fixed together by bolts (the rail support and the rail are also fixed to the sleeper by the same bolts). This effectively prevents the rail from shifting laterally, thereby avoiding changes in track gauge and ensuring the safety of train operation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-3 As shown, an integrated rail support pad assembly includes an integrally formed pad 1 and a rail support 2, with the rail support 2 perpendicular to the pad 1. The pad 1 and the rail support 2 are made of high manganese steel composite material, which has the advantage of high strength. The pad 1 is provided with a limiting protrusion 3, and the rail support 2 is located to the side of the limiting protrusion 3. The rail support 2 is provided with a fixing opening 5 and a limiting rib 4. The limiting rib 4 is located on the side of the rail support 2 away from the limiting protrusion 3. The rail is placed on the pad 1, and the rail is located between the limiting protrusion 3 and the limiting rib 4 and below the fixing opening 5.

[0020] How to use the integrated rail support pad assembly: The pad 1 is fixed to the sleeper with rail spikes. The rail is placed on the pad 1 (one side of the rail support 2 is attached to the outer surface of the rail). The rail is located between the limiting protrusion 3 and the limiting stiffener 4 and below the fixing opening 5. That is, the two ends of the bottom of the rail abut against the limiting protrusion 3 and the limiting stiffener 4 respectively and are located below the fixing opening 5. The lower edge of the top of the rail abuts against the top of the rail support 2. The limiting protrusion 3, the limiting stiffener 4 and the rail support 2 all limit the position of the rail. The rail support 2 and the end of the rail are fixed together with bolts (the rail support 2 and the rail are also fixed to the sleeper with the same bolts). This effectively prevents the rail from shifting laterally, thereby avoiding changes in track gauge and ensuring the safety of train operation.

[0021] The integrated rail support pad assembly of this embodiment has the pad 1 and rail support 2 integrally formed, which has a simple structure and is convenient for fixing the rail. In addition, the limiting protrusion 3, the limiting rib plate 4 and the rail support 2 all limit the position of the rail, thereby effectively preventing the rail from shifting laterally.

[0022] In one possible implementation, the rail brace 2 includes a horizontal plate 21 and two side plates 22, which are integrally formed. The horizontal plate 21 is parallel to the pad 1, and the side plates 22 are perpendicular to the pad 1. The two side plates 22 are fixedly mounted on the pad 1 and arranged symmetrically. The horizontal plate 21 is fixedly connected between the two side plates 22, and there is a space between the horizontal plate 21 and the pad 1. Two fixing openings 5 ​​are provided and are respectively provided on the two side plates 22 and correspond to each other. Two limiting ribs 4 are provided and are respectively fixedly mounted between one side plate 22, the horizontal plate 21, and the pad 1, and between the other side plate 22, the horizontal plate 21, and the pad 1. The two limiting ribs 4 are respectively located above the two fixing openings 5. The space between the horizontal plate 21 and the pad 1 allows the rail to pass through the space and then abut against the limiting protrusion 3 and the limiting rib 4 respectively. The setting of the limiting ribs 4 further strengthens the connection strength between the pad 1 and the rail brace 2. Specifically, the rail is placed on the pad 1, with the two ends of the bottom of the rail abutting against the limiting protrusion 3 and the limiting rib plate 4 respectively, and located below the fixed opening 5, while the lower edge of the top of the rail abuts against the top of the horizontal plate 21.

[0023] In one possible implementation, the pad 1 has multiple first fixing holes 11 and second fixing holes 12 on both sides. The limiting protrusion 3 has multiple notches. Each first fixing hole 11 is located directly below the notch, and each second fixing hole 12 is on the same straight line as the connection between the limiting rib 4 and the pad 1. Bolts pass through the notches and first fixing holes 11 and are then fixed to the sleeper. The bolts fix one end of the rail to the rail support 2, and also fix the rail support 2 and the rail to the sleeper. Bolts pass through the second fixing holes 12 and are then fixed to the sleeper. The bolts fix the other end of the rail to the rail support 2, and also fix the rail support 2 and the rail to the sleeper.

[0024] In one possible implementation, the pad 1 has third fixing holes 13 on both sides, and a plurality of first fixing holes 11 and second fixing holes 12 are located between two third fixing holes 13. Rail spikes pass through the third fixing holes 13 to fix the pad 1 to the sleeper.

[0025] In one possible implementation, fixing sleeves 6 are provided on both sides of the pad 1. The two fixing sleeves 6 are located outside the two third fixing holes 13. A fixing rod 7 is fixedly installed in each fixing sleeve 6. Both ends of the fixing rod 7 are located outside the pad 1, and both ends of the fixing rod 7 are provided with pin holes. The pin passes through the pin holes of the fixing rod 7 and is fixed to the sleeper. The fixing rod 7 further limits the position of the pad 1, thereby ensuring the stability of the rail and effectively preventing lateral displacement of the rail.

[0026] As one possible implementation, each of the limiting stiffeners 4 is L-shaped, and each of the limiting stiffeners 4 and the fixing opening 5 is provided with an arc. The arc of the limiting stiffeners 4 and the arc of the fixing opening 5 match the arc of the rail end, ensuring that the rail end is completely fitted against the limiting stiffeners 4 and that the arc position of the bottom of the rail is completely fitted against the fixing opening 5, ultimately keeping the rail stable and preventing lateral displacement of the rail.

[0027] As one possible implementation, the width of the side plate 22 gradually increases from the top to the bottom. The structural arrangement of the side plate 22 makes the rail brace 2 and the pad 1 more stable, thereby making the rail brace 2 more stable when supporting the rail.

[0028] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of this utility model should be included within the scope of the patent application of this utility model.
