Description

Technical Field

[0001] The utility model relates to the technical field of railway bridges, in particular to a ballast retaining device at the end of a railway bridge beam. Background Art

[0002] At present, the ballast caps at the ends of railway bridge beams are buried at the bottom of the railway track ballast all year round. The ballast caps are prone to rust, damage and tilt, causing bridge ballast to gradually leak out from the damaged parts of the ballast caps and the gaps between the ballast caps and the ends of the bridge beams. If the ballast leakage problem is not dealt with in time, it will affect the geometric state of the railway line and even endanger the safety of train operation.

[0003] After analysis and research, the reasons for the rust and damage of the ballast cover are: the ballast cover is made of ordinary steel, which is not only prone to rust in a humid environment, but also prone to wear under the rolling of trains, causing the ballast cover to rust, rot and damage. As the rust worsens, the bridge ballast gradually leaks out from the damaged part of the ballast cover; the reason why the ballast cover is skewed is: the ballast cover is a whole plate, and its bottom plate and its side plates, as well as its side plates and its top plates are fixedly connected. Due to factors such as the tamping of the line on the bridge, the ballast cover vibrates slowly to one side, causing it to skew, or the heights of the beam ends on both sides of the railway bridge are inconsistent. When the train passes, the ballast cover vibrates and deviates to the lower beam end, causing the ballast cover to skew.

[0004] In order to ensure the effectiveness of the remediation of ballast leakage defects at the beam ends of masonry bridges, it is currently necessary to measure the beam end form in advance, which requires an extra skylight point, which not only wastes railway skylight resources, but also increases the workload.

[0007] According to the device for retaining ballast at the end of a railway bridge beam in an embodiment of the utility model, on the one hand, by movably connecting the bottom plate, the side plate and the top plate of the ballast retaining cover plate in sequence along the length direction of the bridge ballast trough, the ballast retaining cover plate can be flexibly adjusted according to the actual angle on site, so that the bottom plate is tightly fitted with the bottom surface of the bridge ballast trough, the side plate is tightly fitted with the inner side surface of the bridge ballast trough, and the top plate is tightly fitted with the outer top surface of the bridge ballast trough, so that the entire ballast retaining cover plate is tightly fitted with the surface of the bridge ballast trough, which can prevent the ballast retaining cover plate from being skewed due to factors such as tamping of the bridge line or passing of trains in the later stage; on the other hand, the bottom plate, the side plate and the top plate are all made of wear-resistant and corrosion-resistant plates, which can prevent the ballast retaining cover plate from being easily rusted and damaged in the later stage.

DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0024] Combine the following Figure 1 to Figure 2 The railway bridge beam end ballast retaining device of the embodiment of the utility model is described.

[0025] like Figure 1 and Figure 2 As shown, the ballast retaining device at the end of a railway bridge beam according to an embodiment of the utility model comprises a ballast retaining cover plate 1, which is used to be arranged on the ballast groove of the railway bridge and buried at the bottom of the ballast of the railway track bed.

[0026] Specifically, the ballast retaining cover 1 includes a bottom plate 101, a side plate 102 and a top plate 103, and one side of the bottom plate 101 and the lower side of the side plate 102, as well as the upper side of the side plate 102 and one side of the top plate 103 are all movably connected, that is, the bottom plate 101, the side plate 102 and the top plate 103 are movably connected in sequence along the length direction of the bridge ballast trough, wherein the bottom plate 101 is used to fit with the bottom surface of the bridge ballast trough, the side plate 102 is used to fit with the inner side surface of the bridge ballast trough, and the top plate 103 is used to fit with the outer top surface of the bridge ballast trough. Since the bottom plate 101, the side plate 102 and the top plate 103 are movably connected in sequence along the length direction of the bridge ballast trough, the ballast cover 1 can be flexibly adjusted according to the actual angle on site, so that the bottom plate 101 is tightly fitted with the bottom surface of the bridge ballast trough, the side plate 102 is tightly fitted with the inner side surface of the bridge ballast trough, and the top plate 103 is tightly fitted with the outer top surface of the bridge ballast trough, that is, the ballast cover 1 is tightly fitted with the surface of the bridge ballast trough, and the ballast cover 1 is prevented from being skewed due to factors such as tamping of the bridge line or passing of trains, thereby avoiding gaps between the ballast cover 1 and any side of the bridge beam end, effectively preventing leakage of roadbed ballast. The bottom plate 101, the side plate 102 and the top plate 103 are all wear-resistant and corrosion-resistant plates, so that the bottom plate 101, the side plate 102 and the top plate 103 can not only resist moisture and will not rust, but also have high hardness and are wear-resistant. They are not easily worn under the rolling of trains. Therefore, the bottom plate 101, the side plate 102 and the top plate 103 are not easy to rust and damage, and can further effectively prevent the leakage of the ballast of the roadbed.

[0027] According to the railway bridge beam end ballast retaining device of the embodiment of the utility model, on the one hand, by sequentially movably connecting the bottom plate 101, the side plate 102 and the top plate 103 of the ballast retaining cover plate 1 along the length direction of the bridge ballast trough, it can be flexibly adjusted according to the actual angle on site, so that the bottom plate 101 is tightly fitted with the bottom surface of the bridge ballast trough, the side plate 102 is tightly fitted with the inner side surface of the bridge ballast trough, and the top plate 103 is tightly fitted with the outer top surface of the bridge ballast trough, that is, the ballast retaining cover plate 1 as a whole is tightly fitted with the surface of the bridge ballast trough, which can prevent the ballast retaining cover plate 1 from being skewed due to factors such as tamping of the bridge line or passing of trains in the later stage; on the other hand, the bottom plate 101, the side plate 102 and the top plate 103 are all made of wear-resistant and corrosion-resistant plates, which can prevent the ballast retaining cover plate 1 from being easily rusted and damaged in the later stage. Since the ballast retaining cover 1 is not prone to skew, rust or damage, the ballast retaining device at the end of the railway bridge beam of the utility model embodiment can effectively prevent leakage of roadbed ballast, has a long service life, greatly delays the maintenance cycle of the railway bridge, saves a lot of human resources and railway transportation resources, and can also reduce railway skylight resources. It can be suitable for various masonry beam joints and meet the needs of various different beam end forms.

[0028] In some embodiments, one side of the bottom plate 101 and the lower side of the side plate 102 and the upper side of the side plate 102 and one side of the top plate 103 are connected by loose-leaf 104, which can be rust-proof loose-leaf. In this way, it can be flexibly adjusted according to the actual angle on site, so that the bottom plate 101 is closely fitted with the bottom surface of the bridge ballast groove, the side plate 102 is closely fitted with the inner side of the bridge ballast groove, and the top plate 103 is closely fitted with the outer top surface of the bridge ballast groove, that is, the ballast cover plate 1 as a whole is closely fitted with the surface of the bridge ballast groove, which can prevent the ballast cover plate 1 from being skewed due to factors such as tamping of the bridge line or passing of trains in the later stage, thereby avoiding the occurrence of leaks between the ballast cover plate 1 and any side of the bridge beam end, effectively preventing the leakage of the roadbed ballast.

[0029] In some embodiments, there are multiple hinges 104 between one side of the bottom plate 101 and the lower side of the side plate 102; there are multiple hinges 104 between the upper side of the side plate 102 and one side of the top plate 103; thus, the connection between the bottom plate 101 and the side plate 102 is reliable and can be flexibly adjusted according to the actual angle on site, so that the bottom plate 101 is tightly fitted with the bottom surface of the bridge ballast trough, the side plate 102 is tightly fitted with the inner side surface of the bridge ballast trough, and the top plate 103 is tightly fitted with the outer top surface of the bridge ballast trough, so that the ballast cover 1 as a whole is tightly fitted with the surface of the bridge ballast trough, which can prevent the ballast cover 1 from being skewed due to factors such as tamping of the bridge line or passing of trains in the later stage, thereby avoiding gaps between the ballast cover 1 and any side of the bridge beam end, effectively preventing the leakage of roadbed ballast.

[0030] In some embodiments, there are two hinges 104 between one side of the bottom plate 101 and the lower side of the side plate 102; there are two hinges 104 between the upper side of the side plate 102 and one side of the top plate 103; thus, the connection between the bottom plate 101 and the side plate 102 is reliable and can be flexibly adjusted according to the actual angle on site, so that the bottom plate 101 is tightly fitted with the bottom surface of the bridge ballast trough, the side plate 102 is tightly fitted with the inner side surface of the bridge ballast trough, and the top plate 103 is tightly fitted with the outer top surface of the bridge ballast trough, so that the ballast cover 1 as a whole is tightly fitted with the surface of the bridge ballast trough, which can prevent the ballast cover 1 from being skewed due to factors such as tamping of the bridge line or passing of trains in the later stage, thereby avoiding gaps between the ballast cover 1 and any side of the bridge beam end, effectively preventing leakage of roadbed ballast.

[0031] In some embodiments, a fixing portion 1011 fixed to the bottom surface of the bridge ballast trough is provided on the bottom plate 101. Through the fixing portion 1011, the bottom plate 101 can be fitted and fixed to the bottom surface of the bridge ballast trough, further effectively preventing the ballast cover plate 1 from being relatively displaced or skewed on the surface of the bridge ballast trough, thereby avoiding the formation of gaps between the ballast cover plate 1 and any side of the bridge beam end, effectively preventing leakage of roadbed ballast.

[0032] In some embodiments, the fixing portion 1011 is a fixing hole, so that a protruding column fixed to the bridge ballast trough, such as an anti-rust stud, can be passed through the fixing hole to achieve the fit and fixation of the base plate 101 to the bottom surface of the bridge ballast trough, and the fixed installation is simple and reliable.

[0033] In some embodiments, the fixing holes are distributed in multiple rows, so that the bottom plate 101 can be fixed to the bottom surface of the bridge ballast trough, and the fixing installation is simple and reliable.

[0034] In some embodiments, there are multiple fixing holes in each row, and the multiple fixing holes are arranged at intervals along the width direction of the bridge ballast groove, so that the bottom plate 101 can be fitted and fixed to the bottom surface of the bridge ballast groove, and the fixed installation is simple and reliable.

[0035] In some embodiments, multiple rows of fixing holes are spaced apart along the length direction of the bottom plate 101, so that the bottom plate 101 can be fixedly fitted to the bottom surface of the bridge ballast trough, and the fixing and installation is simple and reliable.

[0036] In some embodiments, Figure 1 As shown, the side plate 102 is a whole plate, that is, the ballast retaining cover plate 1 is a whole plate, which is easy to install.

[0037] In some embodiments, Figure 2 As shown, the side plate 102 includes a lower side plate 1021 and an upper side plate 1022, the upper portion of the lower side plate 1021 and the lower portion of the upper side plate 1022 are overlapped and connected, and the overlapping portion (see Figure 2 The size of the hatched part in the middle) is adjustable. That is, by cutting the side plate 102 horizontally, the ballast retaining cover plate 1 is designed into two independent parts, one of which is a structural component formed by the movable connection of the bottom plate 101 and the lower side plate 1021, and the other is a structural component formed by the movable connection of the upper side plate 1022 and the top plate 103. In this way, for various different lengths of the inner side surface of the bridge ballast trough, by adjusting the size of the overlapping part between the upper part of the lower side plate 1021 and the lower part of the upper side plate 1022, the length of the side plate 102 after the overlap connection is matched with the length of the inner side surface of the bridge ballast trough, thereby expanding the scope of application of the railway bridge beam end ballast retaining device of this embodiment.

[0038] In some embodiments, a first long through groove 10211 is provided on the lower side plate 1021, and a second long through groove 10221 is provided on the upper side plate 1022. The extension direction of the first long through groove 10211 and the extension direction of the second long through groove 10221 are both the length direction of the inner side surface of the bridge ballast groove. Therefore, when the upper part of the lower side plate 1021 and the lower part of the upper side plate 1022 are overlapped and connected, the first long through groove 10211 and the second long through groove 10221 overlap in part or in whole, and the protruding column (such as an anti-rust bolt) fixed on the inner side surface of the bridge ballast groove passes through the corresponding overlapping part of the first long through groove 10211 and the second long through groove 10221, thereby realizing the fixed connection between the lower side plate 1021 and the upper side plate 1022, further preventing the ballast cover plate 1 from being skewed, and the size of the overlapping part is adjustable.

[0039] In some embodiments, there are two first long through grooves 10211, and the two first long through grooves 10211 are two spaced first notch grooves distributed on the upper part of the lower side plate 1021; there are two second long through grooves 10221, and the two second long through grooves 10221 are two spaced second notch grooves distributed on the lower part of the upper side plate 1022. Therefore, when the upper part of the lower side plate 1021 and the lower part of the upper side plate 1022 are overlapped and connected, the first long through groove 10211 and the second long through groove 10221 are partially or completely overlapped, and the bosses (such as anti-rust bolts) fixed on the inner side of the bridge ballast groove pass through the corresponding overlapping parts of the first long through groove 10211 and the second long through groove 10221, thereby realizing the fixed connection between the lower side plate 1021 and the upper side plate 1022, the fixed connection is reliable, further preventing the ballast cover plate 1 from being skewed, and the size of the overlapping part is adjustable.

[0040] In some embodiments, the bottom plate 101, the side plate 102 and the top plate 103 are all hot-dip galvanized stainless steel plates. Therefore, the ballast retaining cover plate 1 can resist moisture and will not rust, and at the same time has high hardness and wear resistance, which greatly prolongs the service life of the ballast retaining steel plate, delays the maintenance cycle, and saves a lot of human resources.

[0041] It should be noted that for curved railway bridges with large leaks at the outer beam ends, the size of the ballast cover 1 is unreasonable, and the outer beam ends leak ballast due to insufficient width of the ballast cover 1. The width of the ballast cover 1 can be appropriately increased to prevent leakage of the roadbed ballast.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0043] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
