Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling object devices on the outer side of the sidewalk of overpasses on urban roads crossing ordinary-speed railways, and particularly relates to an anti-falling object device on the outer side of the sidewalk of overpasses on urban roads crossing ordinary-speed railways. Background Technique

[0002] The anti-falling object device on the outer side of the sidewalk of overpasses on urban roads crossing ordinary-speed railways generally refers to a safety facility designed to prevent objects from falling from the sidewalk or bridge into the railway area. These devices are designed to ensure the safety of urban transportation facilities and prevent situations that may pose risks to railway lines and passing trains.

[0003] When the existing anti-falling object device on the outer side of the sidewalk of overpasses on urban roads crossing ordinary-speed railways is in use,

[0004] the safety performance is poor. In the case of extreme strong wind weather, the safety of railway operation under the overpass on urban roads crossing ordinary-speed railways and the safety of pedestrians on the overpass on urban roads crossing ordinary-speed railways cannot be guaranteed. The device is not easy to disassemble, and the maintenance and repair work will become complicated and time-consuming. Technicians may need more time and resources to handle damaged components. The non-easy-to-disassemble structure limits the flexibility of the equipment, making it difficult to adjust or move according to actual needs, reducing the applicability. The fixed structure may occupy a large space, making transportation inconvenient, increasing the transportation cost and difficulty, especially in occasions where frequent transfer is required.

[0005] In view of the above problems, the utility model provides an anti-falling object device on the outer side of the sidewalk of overpasses on urban roads crossing ordinary-speed railways. Content of the Utility Model

[0006] The purpose of the utility model is to provide an anti-falling object device on the outer side of the sidewalk of overpasses on urban roads crossing ordinary-speed railways. The utility model can provide protection for pedestrians in extreme weather and can be quickly disassembled, thus solving the problems in the background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: an anti-falling object device on the outer side of the sidewalk of overpasses on urban roads crossing ordinary-speed railways, including columns, large frames, a first protection net and connectors. The columns are H-shaped steel reinforced columns, and the bottom ends of the columns are welded and fixed to the embedded steel plates of the sidewalk railing bases; the large frames are formed by welding L-shaped equal-angle steel bars, and the vertical bars of the large frames are connected to the columns by bolts; the first protection net adopts a double-layer welded wire mesh sheet of 20×20mm and 5×5mm. A flat steel small frame is arranged on the outer side of the first protection net, and the wire of the mesh sheet is connected to form a second protection net by welding on the small frame; the second protection net is connected and fixed to the large frame by bolts, and finally a complete anti-falling object device is formed.

[0008] Furthermore, fixed arc plates are welded on the surface of the column. The number of the fixed arc plates is four, achieving the effect of facilitating the fixation of the column.

[0009] Furthermore, the connecting piece includes a screw and a nut which are internally thread-connected for fixing the large frame. A threaded hole is formed on one side of the column, achieving the effect of fixing the large frame.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] A falling object prevention device on the outer side of the sidewalk of an overpass on an urban road spanning a general speed railway provided by the present utility model

[0012] Through the arrangement of the column and the large frame, the overall wind resistance of the falling object prevention net device can be greatly enhanced, effectively ensuring the protection of the railway traffic safety under the overpass spanning the general speed railway and the pedestrian passage safety on the overpass in case of extreme strong wind weather. At the same time, each component has strong independence and can be welded into a whole in the factory and then spliced and installed on site, improving the overall quality of the components and the construction progress. The maintenance and repair work of the equipment is made more convenient through the easy-to-dismantle design. Technicians can quickly remove and replace damaged parts. The device can be adjusted or moved according to actual needs, enhancing the flexibility of the structure, being applicable to different scenarios and uses. The volume of the disassembled parts is small, making it easier to store and transport, reducing the transportation cost and space occupation. BRIEF DESCRIPTION OF THE DRAWINGS
