Technical Field

[0001] This utility model relates to the field of bridge pedestrian slab technology, specifically to a device for preventing loosening of railway bridge pedestrian slabs. Background Technology

[0002] Railway bridge walkways are primarily used as passageways for maintenance personnel to inspect, patrol, or repair the tracks, as well as as temporary storage areas for tools, ballast, sleepers, or rails during maintenance. Currently, railway bridge walkways are located on one side of the railing without effective fixation. In strong winds or with the wind pressure generated by passing trains, there is a risk of the walkways being lifted. To prevent strong winds from adversely affecting the stability of the walkways, or even blowing them away, a device to prevent loosening of railway bridge walkways needs to be designed to secure them.

Detailed Implementation

[0029] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0030] Example 1: like Figures 1-3 The present invention relates to a railway bridge walkway anti-loosening device, which includes a support uniformly fixed to the side of the bridge 1 and a walkway 7 horizontally laid between adjacent supports. A pressure strip 8 is provided above the joint of the adjacent walkway 7. One end of the pressure strip 8 is fixed to the outer end of the support, and the other end is fixed to the connecting plate 5 fixed to the outer side of the bridge 1. Reference Figures 1-4 , Figure 6 The bracket is fixed to the side of the bridge 1 by U-bolts 13 pre-embedded inside the bridge 1. The connecting plate 5 is fixed between the side of the bridge 1 and the bracket by U-bolts 13. In the past, the U-bolts 13 between the side of the bridge 1 and the bracket were provided with two circular washers. In this utility model, the vertical strip-shaped connecting plate 5 is used to replace the existing washers, which cleverly utilizes the connection structure of the bridge itself to realize the installation and fixing of the pressure strip 8. In this embodiment, the inner end of the pressure strip 8 is provided with an upwardly curved arc-shaped bend 9, and the outer end of the pressure strip 8 is provided with a right-angle bend 10 connected to the outer end of the bracket. The connecting plate 5 has a clearance hole 6 corresponding to the arc-shaped bend 9, and the right-angle bend 10 is connected to the bracket by a bolt assembly. After the arc-shaped bend 9 passes through the clearance hole 6, the outer end of the right-angle bend 10 is connected to the bracket by the bolt assembly. The cooperation between the arc-shaped bend 9 and the clearance hole 6 can prevent the inner end of the pressure strip 8 from coming out.

[0031] like Figures 1-7 As shown, the bracket includes a first bracket and / or a second bracket, and the pressure strip includes a first pressure strip 801 corresponding to the first bracket and a second pressure strip 802 corresponding to the second bracket; Reference Figure 4 The first support includes a vertical beam 2 connected to the bridge 1 and a horizontal beam 3 fixed to the top of the vertical beam 2. A column 4 is vertically fixed to the upper part of the outer end of the horizontal beam 3. The right-angle bend 10 at the outer end of the first pressure strip 801 is bent upward and fixed to the column 4 by bolt assembly. Several sets of bolt assembly are provided, at least one set is provided at the lower end of the column 4 near the horizontal beam 3. Reference Figure 6The second support includes a vertical beam 2 connected to the bridge 1 and a horizontal beam 3 fixed to the top of the vertical beam 2. The right-angle bend 10 at the outer end of the second pressure strip 802 is bent downwards and fixed to the outer end of the horizontal beam 3 by bolt assembly. Specifically, the horizontal beam 3, the vertical beam 2, and the column 4 are all L-shaped angle steel. An mounting plate 301 is welded to the outer end of the horizontal beam 3 of the second support, and the right-angle bend 10 at the outer end of the second pressure strip 802 is connected to the mounting plate 301.

[0032] As a further optimization, such as Figure 5 and Figure 7 As shown, the right-angle bends 10 in the first pressure strip 801 and the second pressure strip 802 are identical detachable L-shaped plates. The horizontal part 11 of the L-shaped plate is bolted to the upper part of the outer end of the pressure strip 8. The vertical parts 12 of the L-shaped plates in the first pressure strip 801 and the second pressure strip 802 are respectively arranged facing upwards and downwards. The first pressure strip 801 and the second pressure strip 802 installed at the first bracket and the second bracket can be assembled using the same parts. In use, the upward and downward orientation of the right-angle bends 10 is selected according to the bracket type. By producing the same parts, pressure strips for different bracket types can be installed, which is convenient to use and has good applicability.

[0033] As a further optimization, the upper two sides of the pressure strip 8 are provided with chamfers or rounded corners, so that the step difference between the edge of the pressure strip 8 and the walking board 7 is small or non-existent, ensuring walking safety.

[0034] As a further optimization, a limiting hole is provided on the arc-shaped bend 9 on the inner side of the connecting plate 5, and a latch is provided in the limiting hole. By providing the limiting hole and the latch, the arc-shaped bend 9 can be limited to the inner side of the connecting plate 5, which can prevent the left end of the pressure strip 8 from coming out of the clearance hole 6.

[0035] In this embodiment, the U-shaped part of the U-bolt 13 is embedded inside the bridge 1, and its two threaded connection parts face outward horizontally. The threaded connection parts pass through the vertical beam 2 of the bracket and are locked by nuts. The connecting plate 5 is located between the bridge 1 and the vertical beam 2, and the connecting plate 5 has through holes corresponding to the threaded connection parts.

[0036] Example 2: Reference Figures 8-11 , Figure 13 The difference between this embodiment and embodiment 1 is that the connecting plate 5 is set on the bridge 1 in a different way. Specifically, the bracket is fixed to the side of the bridge 1 by a T-shaped steel embedded in the bridge, and the connecting plate 5 is fixed to the upper end of the T-shaped steel. By extending the connecting plate 5 from the upper end of the T-shaped steel, the connecting plate 5 is firmly fixed to the bridge. There is no need to install and fix the connecting plate 5 later. The structure is simple and reliable.

[0037] Reference Figures 10-11and Figure 13 The T-shaped steel includes a pre-embedded part 14 vertically embedded inside the bridge and a connecting part 15 vertically arranged outside the pre-embedded part 14. The vertical beam 2 of the bracket is connected to the connecting part 15 by a bolt assembly. The connecting plate 5 is fixedly connected to the upper end of the pre-embedded part 14 parallel to the outer wall of the bridge 1.

[0038] Reference Figure 12 and Figure 14 As a further optimization, the first pressure strip 801 and the second pressure strip 801 set at the first bracket and the second bracket can also be assembled using the same parts. By producing the same parts, the installation of pressure strips for different bracket types can be achieved.

[0039] The anti-loosening device can be applied to bridges 1 in both Embodiment 1 and Embodiment 2. The pedestrian slab 7 is limited on the crossbeam 3 by the pressure strip 8, which can prevent the pedestrian slab 7 from being blown away by strong winds. It is firmly and reliably fixed and easy to construct.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
