[0032] The following is combined with Figure 1-3This application is described in further detail.

[0033] The present application embodiment discloses a quick installation structure for connecting ribs of a gas tunnel arch frame. Figure 1 The quick installation structure of the gas tunnel arch connecting rib comprises an arch 1 and connecting ribs 2, wherein the arch 1 has a plurality of connecting ribs distributed in the horizontal direction. In the embodiment of the present application, the arch 1 is selected as an I-shaped steel arch. Specifically, the arch 1 comprises two wing plates and a web 103. In the embodiment of the present application, the wing plate located inside the arch 1 is set as an inner wing plate 101, and the wing plate located outside the arch 1 is set as an outer wing plate 102. Both sides of the web 103 are fixedly mounted on the inner wing plate 101 and the outer wing plate 102, respectively.

[0034] Reference Figure 1 and Figure 2 The connecting ribs 2 are located on the outside of the arch frame 1, that is, on the side of the outer wing plate 102 away from the inner wing plate 101. There are multiple connecting ribs 2 evenly distributed around the axis of the arch frame 1. To facilitate the connection between the arch frame 1 and each connecting rib 2, a plurality of connecting sleeves 3 are provided on the side of the outer wing plate 102 away from the inner wing plate 101. The plurality of connecting sleeves 3 and the connecting ribs 2 are provided one by one. Each connecting sleeve 3 has a through hole 4 provided along its own axis for the connecting rib 2 to pass through. When the connecting rib 2 passes through the through hole 4 of each connecting sleeve 3, the connection between the connecting rib 2 and each arch frame 1 is realized.

[0035] Reference Figure 1 and Figure 3 Specifically, the outer wing plate 102 is provided with a plurality of adjustment holes 5 which are arranged through the outer wing plate 102. A plurality of adjustment holes 5 are arranged corresponding to the connecting sleeve 3 one by one, and each adjustment hole 5 extends circumferentially around the axis of the outer wing plate 102. The connecting sleeve 3 is fixedly provided with a mounting screw 6 which is slidably fitted in the adjustment hole 5. One end of the mounting screw 6 which is passed through the adjustment hole 5 is threadedly fitted with a mounting nut 7, so that the mounting screw 6 and the connecting sleeve 3 can be fixed in position by screwing the mounting nut 7.

[0036] Reference Figure 2 and Figure 3 In addition, the mounting screw 6 is also threadedly matched with an adjusting nut 8, which is located on the side of the outer wing plate 102 away from the mounting nut 7. The mounting nut 7 and the adjusting nut 8 are both fixedly connected with abutment pads 9 on the side close to the outer wing plate 102. The material of the abutment pads 9 is selected as rubber to increase the contact area between the mounting nut 7 and the adjusting nut 8 and the outer wing plate 102 when the connecting sleeve 3 is fixed, thereby fully ensuring the stability of the position of the connecting sleeve 3 when it is fixed. The setting of the adjusting nut 8 facilitates the connection sleeve 3 to be fixed at different radial positions of the arch frame 1 through the adjusting nut 8, thereby facilitating the full flexibility of the installation position of the connecting sleeve 3 and facilitating adaptation to different installation situations.

[0037] Reference Figure 3 In order to fully ensure the stability of the connection rib 2 and the connection sleeve 3 when they are fixed, the connection sleeve 3 is provided with a fixing part, which includes a fixing bolt 10. The fixing bolt 10 is passed along an axis perpendicular to the connection sleeve 3 and threadedly engaged with the connection sleeve 3. One end of the fixing bolt 10 is passed through the through hole 4, so that the connection rib 2 in the connection sleeve 3 is tightly fixed by the fixing bolt 10 to ensure the stability of the position of the connection rib 2. The end of the fixing bolt 10 extending into the through hole 4 is rotatably provided with an arc clamping plate 11, and the arc clamping plate 11 is slidably engaged with the through hole 4 along the axis direction perpendicular to the connection sleeve 3. When the fixing bolt 10 is pressed against the connection rib 2 to fix it, the connection rib 2 is located in the area surrounded by the arc clamping plate 11, so as to further limit the position of the connection rib 2 when it is fixed.

[0038] Reference Figure 2 and Figure 3 In order to facilitate the insertion of the connecting rib 2 into the through hole 4 of the connecting sleeve 3, the openings of the through hole 4 at both ends are rounded, so that the aperture of the through hole 4 near its own opening is larger than the aperture of the through hole 4, so that there is a certain gap transition when the connecting rib 2 is inserted into the through hole 4. Limiting steel wires 12 are provided on both sides of each connecting sleeve 3, and the limiting steel wires 12 are fixed to the connecting rib 2 by binding, so that the relative position stability of the connecting rib 2 and the connecting sleeve 3 when the connecting rib 2 is fixed is further ensured by the limiting effect of the limiting steel wires 12 on the connecting sleeve 3.

[0039] The implementation principle of the quick installation structure of the connecting rib of the gas tunnel arch frame of the present application embodiment is as follows: when it is necessary to connect the connecting rib 2 and each arch frame 1, firstly, the connecting rib 2 is sequentially inserted into the connecting sleeve 3 of each arch frame 1, and the connecting sleeve 3 and the connecting rib 2 are fixed by the fixing bolt 10 to realize the connection between the connecting rib 2 and each arch frame 1. During the connection process of the connecting rib 2 and each arch frame 1, it is not necessary to fix them with each arch frame 1 sequentially by welding. The connecting rib 2 is inserted into the through hole 4 in each connecting sleeve 3 and fixed by the fixing member. The operation is convenient, which is conducive to improving the working efficiency of the connection between the connecting rib 2 and each arch frame 1. In addition, the setting of the adjustment hole 5 and the adjustment bolt facilitates the multi-directional micro-adjustment of the position of the connecting sleeve 3 during installation, which facilitates the adaptability of the connecting sleeve 3 to different installation conditions, and has strong applicability. The setting of the limiting steel wire 12 plays a further limiting role on the connecting sleeve 3 and the connecting rib 2, so as to further ensure the stability of the relative position of the connecting sleeve 3 and the connecting rib 2 when they are fixed.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
