DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1 As shown, a typical embodiment of the present invention provides a detachable inverted arch trestle protection device, including a main structure 1, a central protection component 2 and a side protection component 3, the main structure 1 is provided with two rows for vehicles and personnel to walk, the central protection component 2 is arranged between the two rows of main structures 1, the side protection component 3 is arranged on the outside of the main structure 1, the central protection component 2 is detachably connected to the inner side of the main structure 1, and the side protection structure is detachably connected to the main structure 1.

[0035] In this embodiment, the two main structures 1 are used for vehicles to pass through and people to walk. The central protection assembly 2 is not only used to effectively protect the area between the two main structures 1, but also the width of the main structure 1 can be reduced by setting the central protection assembly 2 to reduce the weight and cost of the overall protection device, making the overall protection device easier to install and disassemble. The side protection assembly 3 is used to protect the outer area of ​​the main structure 1. In addition, the detachable connection method of the main structure 1, the central protection assembly 2 and the side protection assembly 3 greatly facilitates the installation and disassembly of the overall protection device.

[0036] The main structure 1 includes multiple I-beams 1.1 connected in sequence in the transverse direction. Specifically, in this embodiment, multiple I-beams 1.1 are connected in the transverse direction to achieve transverse coverage of the main structure 1. The main structure 1 formed by the splicing of multiple I-beams 1.1 has sufficient strength and stability to ensure that the protective device has sufficient safety and passability.

[0037] like Figure 7 , Figure 8 , Fig.12 and Fig.15 As shown, the main structure 1 further includes a transverse connecting plate 1.2, and the multiple I-beams 1.1 are arranged in the longitudinal direction, and the transverse connecting plate 1.2 connects the multiple I-beams 1.1 in the transverse direction. In this embodiment, the transverse connecting plate 1.2 effectively connects and fixes the multiple I-beams 1.1 spliced ​​into the main structure 1 in the transverse direction, which not only improves the overall stability and strength of the main structure 1, but also forms an uneven plane on the upper surface of the main structure 1 by the transverse connecting plate 1.2, which can improve the limiting effect and anti-skid effect on the vehicle body when the vehicle body passes, and further improve the safety of vehicle passage.

[0038] The multiple I-beams 1.1 are provided with a socket 1.3, and the lower surface of the transverse connecting plate 1.2 is fixedly installed with a fastening stud 1.4, which is connected with a fastening nut 1.5 after passing through the socket 1.3. In the process of using the multiple I-beams 1.1 to splice the main structure 1, in the horizontal direction, each fastening stud 1.4 is directly passed downward through the socket 1.3 on each multiple I-beam 1.1, and then the fastening nut 1.5 is connected to the fastening stud 1.4 from the bottom end of the multiple I-beams 1.1, and the transverse connecting plate 1.2 is fixed to the main structure 1.

[0039] like Figure 2 , Figures 5 to 11 , Fig.13 and Fig.14 As shown, the side protection assembly 3 includes a side support, a long tube 3.1, a guardrail 3.2, a side buckle 3.3 and a sleeve 3.4. The inner end of the side support is connected to the main structure 1 on the corresponding side. Three long tubes 3.1 are arranged in sequence in the height direction of the side support. The inner sides of the long tubes 3.1 on the upper and lower sides are fixedly installed with sleeves 3.4. A side buckle 3.3 is arranged at the upper and lower ends of both sides of the guardrail 3.2, and the side buckle 3.3 is inserted into the sleeve 3.4.

[0040] The long tube 3.1 connects the side supports on the same side into a whole, which can improve the overall stability. Specifically, in this embodiment, the side supports are provided with tube holes 3.5 for the long tube 3.1 to pass through. The long tube 3.1 is connected to all the side supports by passing through the tube holes 3.5.

[0041] The guardrail 3.2 is inserted into the sleeve 3.4 through the side buckle 3.3 to achieve quick installation and removal. In this embodiment, the guardrail 3.2 completely covers the space between two adjacent side supports, and the sleeve 3.4 can limit the long tube 3.1 in the length direction of the main structure 1, so that the long tube 3.1 will not move relative to the side support in its length direction, thereby improving the stability of the long tube 3.1. At the same time, the guardrail 3.2 improves the stability between the upper and lower sleeves 3.4 by connecting the upper and lower sleeves 3.4.

[0042] like Fig. 9 and Fig.11 As shown, in a relatively specific embodiment, an "L"-shaped mounting bolt 4 is fixedly mounted on one side of the sleeve 3.4, a through hole 5 for the mounting bolt 4 to pass through is provided on the long tube 3.1, and a mounting screw is connected to a mounting nut 6 after passing through the through hole 5. Such an arrangement enables the sleeve 3.4 to be detachably connected to the long tube 3.1, and further, after the sleeve 3.4 is removed from the long tube 3.1, it is more convenient for the long tube 3.1 to be inserted into or withdrawn from the tube hole 3.5 on the side support.

[0043] like Figure 2 and Figure 4 As shown, a plurality of side supports are equidistantly arranged in the length direction of the main structure 1, and the side supports include a transverse I-beam 3.6 and a longitudinal I-beam 3.7. The transverse I-beam is connected to the bottom of the main structure 1, and the longitudinal I-beam 3.7 is vertically installed on the outer end of the upper surface of the transverse I-beam 3.6. Specifically, two pipe holes 3.5 distributed up and down are opened on the longitudinal I-beam, and one pipe hole 3.5 is opened on the outer end of the transverse I-beam 3.6.

[0044] like Figure 4 As shown, a buffer gap 7 is provided between the longitudinal I-beam 3.7 and the outer side surface of the main structure 1 , and a steel bar 8 is provided between two adjacent transverse I-beams 3.6 in the length direction, and the steel bar 8 is located in the buffer gap 7 .

[0045] like Figure 8 As shown, in a relatively specific embodiment, the steel bar 8 is a threaded steel bar, and three threaded sleeves 9 and a smooth sleeve 10 are fixedly installed on the upper surface of the transverse I-beam 3.6 corresponding to the buffer gap 7. The three threaded sleeves 9 are sequentially distributed in the transverse direction, and the three smooth sleeves 10 are sequentially distributed in the transverse direction. One end of the steel bar 8 is inserted into the smooth sleeve 10, and the other end of the steel bar 8 is threadedly installed in the threaded sleeve. This arrangement makes the steel bar 8 more stable and convenient to install and remove.

[0046] like Figure 2 , Figure 6 , Fig.12 and Fig.14 As shown, a side short tube 11 is provided at the bottom of the steel bar 8, the bottom end of the fastening stud 1.4 corresponding to the position of the side short tube 11 passes through the side short tube 11, and the fastening nut 1.5 is located at the bottom of the side short tube 11. The side short tube 11 can support the area of ​​the steel bar 8 between the two transverse I-beams 3.6 from the bottom, thereby improving the stability and compression resistance of the steel bar 8.

[0047] like Fig.14As shown, through holes 12 for fastening studs 1.4 to pass through are provided on both sides of the transverse I-beam 3.6 in the length direction of the main structure 1, and the bottom ends of the fastening studs 1.4 corresponding to the positions of the transverse I-beam 3.6 pass through the through holes 12. Such an arrangement enables the main body to be connected and fixed to the transverse I-beam 3.6 while the multiple I-beams 1.1 are fixed by the transverse connecting plate 1.2 during the process of splicing the main body.

[0048] like Figures 2 to 4 As shown, the central protection assembly 2 includes a central short tube 2.1 and a running pedal 2.2. The end of the running pedal 2.2 is fixedly provided with a central buckle 2.3. The central buckle 2.3 is sleeved on the central short tube 2.1 from top to bottom. The two ends of the central short tube 2.1 are connected to the inner sides of the two main structures 1. Specifically, in this embodiment, the length of the central short tube 2.1 is greater than the distance between two adjacent main structures 1. In the length direction, the two adjacent central short tubes 2.1 are connected and effectively limited by the running pedal 2.2, and in the width direction, the central short tube 2.1 and the running pedal 2.2 are effectively limited by the main structures 1 on both sides. Therefore, while achieving the effect of facilitating installation and disassembly, the central protection assembly 2 has sufficient stability and strength.

[0049] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
