Description

Technical Field

[0001] This utility model relates to the field of skylight protection technology, and in particular to a skylight shielding and protection device for box girders. Background Technology

[0002] Box girders are a common bridge structure, widely used in various bridge projects such as urban viaducts, sea-crossing bridges, and railway bridges due to their excellent mechanical properties and spatial stability. They have a large internal space, and in some cases, skylights are installed to facilitate material transportation, personnel access, and subsequent inspection and maintenance. With the continuous development of the bridge construction industry, relevant specifications and standards have become increasingly comprehensive. To ensure the safety and durability of bridges, clear requirements have been put forward for the protection of box girder skylights. Some bridge design and construction specifications stipulate that box girder skylights must be equipped with effective shielding and protective devices to meet multiple requirements such as waterproofing, dustproofing, and safety. The promulgation of these specifications and standards has prompted bridge construction and operation units to pay more attention to the application and research and development of shielding and protective devices for box girder skylights.

[0003] Advances in materials science have provided more high-performance material options for protective shielding devices, such as high-strength, corrosion-resistant alloys and new composite materials. This has significantly improved the performance and service life of these devices. Continuous improvements in manufacturing processes, such as advanced welding and forming techniques, ensure the manufacturing precision and quality of the protective devices, enabling them to better meet engineering requirements. Furthermore, the widespread application of computer-aided design and finite element analysis in bridge engineering allows for more precise design and mechanical performance analysis of protective shielding devices, optimizing their structure and parameters and improving their reliability and safety. However, even for the same type of box girder, the skylight dimensions can vary. Protective devices are only suitable for skylights of specific types and sizes of box girders, necessitating redesign and customization of these devices. This can severely impact construction progress and may even lead to construction halts. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a box girder skylight shielding and protection device, which aims to improve the existing technology where the skylight sizes of box girders of the same type vary. The protection device is only applicable to skylights of specific types and sizes of box girders, which leads to the need to redesign and customize the protection device. This will seriously affect the construction progress and may even lead to construction stagnation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a box girder skylight shielding and protection device, comprising a support frame, a second support plate fixedly connected to the top center of the support frame, positioning columns fixedly connected to the front and rear sides of the bottom of the second support plate, two through slots opened on the left side of the second support plate, a main plate rotatably connected to the top center of the second support plate, a long plate rotatably connected to the front and rear sides of the top of the main plate, a shielding cover plate rotatably connected to the opposite side of the long plate, an extension plate fixedly connected to the adjacent side of the shielding cover plate, a blind groove opened at the front end of the adjacent side of the shielding cover plate, the adjacent side of the extension plate passing through the corresponding through slot and slidably connected to the inner wall of the corresponding blind groove, two sliders fixedly connected to the front and rear sides of the bottom of the shielding cover plate, the bottom of the sliders slidably connected to the top of the support frame, and a fixing structure provided on the front side of the support frame for fixing the protection device.

[0006] Through the above technical solution: a second support plate is fixedly connected to the top center of the support frame, ensuring the stability and robustness of the device. Positioning columns are fixedly connected to the front and rear sides of the bottom of the second support plate, which can accurately fix the device in the appropriate position, ensuring its stability under various weather conditions. Two through slots are opened on the left side of the second support plate, which not only increases the flexibility of the device but also facilitates maintenance and adjustment. A main board is rotatably connected to the top center of the second support plate, allowing the main board to be adjusted in angle to adapt to different shading needs. Long plates are rotatably connected to the front and rear sides of the top of the main board, and shading covers are rotatably connected to the opposite sides of these long plates, thus forming an adjustable shading system. An extension plate is fixedly connected to the adjacent side of the shading cover. The design of the extension plate not only achieves an adjustable shading effect but also provides additional protection.

[0007] As a further description of the above technical solution:

[0008] The fixed structure includes two support plates. The top of the support plate is fixedly connected to the bottom of the support plate. The front and rear sides of the support plate are rotatably connected to connecting plates. The bottom of the connecting plates are provided with holes at different distances. The top of the connecting plates is threaded with two bolts. The top of the front and rear sides of the support plate is rotatably connected with L-shaped buckles. The top of the support frame is threaded with bolts all around.

[0009] The above technical solution involves two support plates, one at the top and the other at the bottom, which are fixedly connected to ensure the stability of the overall structure. The front and rear sides of the support plate are rotatably connected to connecting plates, which reinforces the fixation of the protective device. The top of each connecting plate is threaded with two bolts, which ensure stability when subjected to heavy loads and external forces. The L-shaped buckle can engage with the hole, which facilitates the fixation of the connecting plate when not needed.

[0010] As a further description of the above technical solution:

[0011] A sealing ring is fixedly connected to the bottom of the support frame, and a nameplate is fixedly connected to the top front side of the support frame.

[0012] The above technical solution ensures good sealing performance when the support frame comes into contact with other surfaces by fixing the bottom of the support frame to the sealing ring. For easy identification and management, a nameplate is also fixedly connected to the top front part of the support frame.

[0013] As a further description of the above technical solution:

[0014] A knob is fixedly connected to the top center of the motherboard, and an anti-slip sleeve is fixedly connected to the outer wall of the knob.

[0015] The above technical solution provides a knob for easy operation, and an anti-slip sleeve is fixedly connected to the outer wall of the knob to provide a better grip and ensure greater stability when operating the knob.

[0016] As a further description of the above technical solution:

[0017] The bottom of the shielding cover is fixedly connected to a support plate three on the side away from each other, and T-shaped blocks are fixedly connected to the front and rear sides of the support plate three.

[0018] Through the above technical solution: In order to further enhance the stability and support of the structure, T-shaped blocks are fixedly connected to the front and rear sides of each support plate. These T-shaped blocks provide additional support points, thereby ensuring the stability and durability of the entire device.

[0019] As a further description of the above technical solution:

[0020] The inner wall of the support frame is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to the outer wall of the T-shaped block.

[0021] Through the above technical solution, the inner wall of the chute and the outer wall of the T-block can be slidably connected, thereby providing better support effect and adaptability for the support frame.

[0022] As a further description of the above technical solution:

[0023] Reflective strips are fixedly connected to both the front and rear sides of the shielding cover, and the reflective strips are all designed symmetrically.

[0024] The above technical solutions ensure that the cover provides good reflective properties under various conditions, thereby enhancing safety and visibility.

[0025] As a further description of the above technical solution:

[0026] A warning sign is fixedly connected to the top center of the cover plate on the left, and an identification sign is fixedly connected to the top center of the cover plate on the right.

[0027] The above technical solution ensures that the warning signs can immediately attract the attention of passersby, thereby serving as reminders and warnings. The signs also contain explanatory information to help users quickly identify and correctly use the equipment.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, rotating the knob causes the two long plates on both sides to rotate. The rotation of the long plates pulls the rotation of the cover plate, and the extension plate slides through the corresponding through groove in the blind groove to achieve the purpose of adjusting the protection width. This allows it to adapt to the differences in skylight design of different types of box girders, expanding its application range. At the same time, the operation process is simple and intuitive, requiring no complicated tools or professional skills, saving operation time, improving work efficiency, and facilitating quick adjustments by staff on site.

[0030] 2. In this utility model, the protective device is fixed to the box girder by bolt one after the connecting plate is extended by rotating it. This ensures that the protective device is fixedly connected to the box girder in the extended state, which increases the overall stability of the protective device. It is not easy for it to shift or deform when subjected to external impact or load. When extension is not required, the connecting plate can be rotated to the front and rear sides of the support plate two. The connecting plate is fixed by the L-shaped buckle engaging with the hole. This makes the protective device suitable for various construction scenarios and avoids occupying too much space. Attached Figure Description

[0045] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 A sealing ring 12 is fixedly connected to the bottom of the support frame 1, a nameplate 13 is fixedly connected to the top front side of the support frame 1, reflective strips 19 are fixedly connected to the front and rear sides of the shielding cover 8, and the reflective strips 19 are all symmetrically designed. A knob 14 is fixedly connected to the top center of the main board 6, and an anti-slip sleeve 15 is fixedly connected to the outer wall of the knob 14.

[0046] Specifically, the sealing ring 12 ensures the stability and sealing of the equipment, the nameplate 13 records the relevant information and markings of the equipment, and to improve safety at night, reflective strips 19 are fixedly connected to the front and rear sides of the shielding cover 8.

[0047] Working principle: After placing the support frame 1 at the box girder skylight position, rotating the knob 14 causes the two side plates 7 to rotate. The rotation of the long plates 7 pulls the rotation of the cover plate 8, and the extension plate 9 slides through the corresponding through groove 5 in the blind groove 10 to achieve the purpose of adjusting the protection width. Different widths can be adjusted by rotating the different main plates 6. Different types of box girders have different skylight designs. The adjustable characteristics of this device enable it to adapt to these differences. It can play a good protective role on railway box girders, highway box girders, and other types of box girders, expanding its application range. At the same time, the operation process is simple and intuitive, without the need for complicated tools and professional skills, which can save operation time, improve work efficiency, and facilitate workers to make quick adjustments on site.

[0048] By extending the connecting plate 202 and fixing it to the box girder with bolts 204, the protective device can be securely connected to the box girder in its extended state, increasing the overall stability of the protective device and making it less prone to displacement and deformation when subjected to external impacts or loads. This effectively ensures the protective effect and reduces safety risks. When extension is not required, the connecting plate 202 can be rotated to the front and rear sides of the support plate 3, and the connecting plate 202 can be fixed by the engagement of the L-shaped buckle 205 with the hole 203. This makes the protective device suitable for various construction scenarios. When the internal space of the box girder is limited and compact operations are required, the connecting plate 202 can be retracted to avoid occupying too much space. At the same time, the bolts 206 around the top of the support frame 1 strengthen the fixation of the support frame 1. This ensures the safety and reliability of the protective device in different states from multiple aspects, providing more reliable safety protection for construction personnel and equipment.
