DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0030] like Figures 1 to 10 As shown, the present invention provides a protective device for a railway bridge, comprising: at least one connecting member 1 and a protective member 2 connected to the connecting member 1, wherein one end of the connecting member 1 is used to connect to the bridge; the protective member 2 comprises a first protective plate body 21 and a first connecting portion 22 arranged on the side of the first protective plate body 21, the first connecting portion 22 has at least one first connecting end, and the first connecting end is connected to the other end of the connecting member.

[0031] In this embodiment, the longitudinal direction refers to the extension direction of the railway bridge, and the transverse and longitudinal directions are perpendicular to each other and are located on the same horizontal plane.

[0032] The connector 1 is used to achieve the connection between the bridge and the guard, wherein the number of the connectors 1 can be multiple, and the multiple connectors 1 can be distributed on the bridge along the longitudinal interval, or can be staggered on the bridge front and back and left and right. In addition, one end of the connector 1 can be directly fixed to the bridge, or can be fixed to the bridge through other components, for example, the other component can be an anti-collision guardrail 8.

[0033] The protective member 2 includes a first protective plate body 21 and a first connecting portion 22 connected to the first protective plate body 21, wherein the first connecting portion 22 can be integrally formed with the first protective plate body 21, or can be separately formed with the first protective plate body 21, such as welded as one, and the first connecting portion has at least one first connecting end, wherein the number of the first connecting ends is equal to the number of connecting members, and the positions of the first connecting ends and the connecting members also correspond, so as to facilitate the fixed connection between the first connecting ends and the connecting members.

[0034] The protective device for a railway bridge provided by the embodiment of the present invention can increase the bearing capacity of the protective member because the protective plate body has an integral force-bearing surface, thereby preventing heavy objects on the bridge or accident vehicles from falling under the bridge and affecting the operational safety of the railway. In addition, a gap is formed between adjacent first connecting ends, and the hands of construction workers can reach the side of the protective plate body away from the bridge through the gap, so that the construction workers can complete the disassembly and installation operations on the bridge deck, thereby improving the convenience of construction.

[0035] Furthermore, the first connecting end is connected to the connecting member 1 by a bolt 112, and an oblong hole 25 is provided on the first connecting end. The provision of the oblong hole 25 can also facilitate the construction workers' hands to reach through the oblong hole to the side of the protective plate body away from the bridge, so that the construction workers can complete the disassembly and installation operations on the bridge deck, thereby improving the convenience of construction. Furthermore, a detachable fine-mesh steel wire mesh can be installed on the oblong hole 25, and the steel wire mesh can be removed during maintenance. When in use, the steel wire mesh is used to block the oblong hole 25 to prevent parabolic objects from being thrown through the oblong hole 25.

[0036] Furthermore, the first connection part 22 is welded to the side of the first protective plate body 21; this embodiment adopts a split setting. On the one hand, the protective parts can be freely assembled according to the needs of customers or the required height of the protective device, which increases the convenience of assembly. On the other hand, the thickness of the first connection part and the first protective plate body can be freely selected. In this embodiment, the longitudinal direction refers to the extension direction of the railway bridge, and the transverse and longitudinal directions are perpendicular to each other and are located on the same horizontal plane. For example: taking the dimension along the transverse direction as the thickness, the thickness of the first connection part is greater than the thickness of the first protective plate body. By increasing the thickness of the bottom of the protective part, the structural strength of the entire protective device is improved.

[0037] Furthermore, the protective member 2 also includes a second protective plate body 23 and a second connecting portion 24 arranged on the side of the second protective body 23, and the second connecting portion 24 has at least one second connecting end; the first protective plate body and the second protective plate body 23 are arranged at intervals along the lateral direction; so that the protective member has a double-layer protective plate, which improves the defense capability of the protective device.

[0038] The projection of the second connection end on the first protective plate body 21 does not overlap with the first connection end; the hands of the construction workers can be extended to the outside through the oblong hole without being blocked by the first protrusion, which is convenient for construction. In addition, the number of the connection pieces is the same as the number of the first connection ends and the second connection ends, and one connection piece is located below the first connection end or the second connection end. For example, Figure 1 As shown, there are four connecting pieces, and the four connecting pieces are arranged alternately front to back and left to right.

[0039] The second connection part 24 is welded on the side of the second protection plate body 23; the thickness of the second connection part is greater than the thickness of the second protection plate body, and an oblong hole is also provided on the second connection end. The function of the second connection part is the same as that of the first connection part, and this embodiment will not be repeated here.

[0040] In order to improve the structural strength of the protective device, a top plate 3 is provided between the top of the first protective plate body 21 and the top of the second protective plate body 23; side plates 4 are provided between the first protective plate body 21 and the two ends of the second protective plate body 23; and a bottom plate 5 is provided between the first connecting portion 22 and the second connecting portion 24. The top plate 3, the side plate 4 and the first protective plate body 21, the top plate 3, the side plate 4 and the second protective plate body 23, and the bottom plate 5 and the first connecting portion 22 and the second connecting portion 24 are fixedly connected by welding.

[0041] As shown in the figure, each side panel 4 is connected to a reinforcing plate 6 at one end close to the bridge, and the bottom of the reinforcing plate 6 is flush with the bottom of the first connecting portion 22. The reinforcing plate 6 can be in direct contact with the bridge. Further, the reinforcing plate 6 connects the first connecting end and the second connecting end to improve the connection strength between the two.

[0042] Further, as shown in the figure, a plurality of reinforcing ribs 7 are provided on the opposite sides of the first protective plate body 21 and the second protective plate body 23, and the reinforcing ribs on the first protective plate body and the reinforcing ribs on the second protective plate body are arranged alternately. In order to facilitate assembly, the width of the reinforcing ribs can be smaller than the distance between the first protective plate body and the second protective plate body.

[0043] In this embodiment, the provided protective parts can be assembled at the construction site or assembled in the factory in advance. After the assembled protective parts are hoisted to the construction site, the protective parts are fixed to the connecting parts by bolts. On the one hand, factory assembly can ensure the welding quality and reduce the construction work time near the railway; on the other hand, it can avoid rust removal, cutting, grinding, welding and other operations above the railway outside the highway bridge, which can greatly reduce the impact of construction and maintenance on railway operations.

[0044] As a preferred embodiment of the connection method between the connecting member and the bridge, the connecting member 1 can be fixedly connected to the bridge through the anti-collision guardrail 8 to increase the connection strength between the protective member 2 and the bridge.
