[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a large-span steel corridor to prevent the detachment of the rod, including a corridor body 1 and a connecting beam 2, a supporting beam 3 is fixedly connected to the bottom of the corridor body 1, a bracket 4 is fixedly connected to the bottom of the supporting beam 3, a cylinder 5 is fixedly connected to the bottom of the bracket 4, a connecting column 6 is fixedly connected to the output end of the cylinder 5, a cone head 12 is fixedly connected to the bottom of the connecting column 6, a collar 7 is slidably connected to the outer wall of the connecting column 6, and a fixing block 8 is fixedly connected to the outer wall of the collar 7 and the outer wall of the connecting column 6, one of the fixing blocks 8 is rotatably connected to a rotating rod 1 9 inside, and a rotating rod 2 10 is rotatably connected to the outer wall of the other fixing block 8, the rotating rod 1 9 is slidably connected to the inside of the rotating rod 2 10, and the rotating rod 2 10 and the rotating rod 1 9 are fixedly connected to a support plate 11 on one side, a fixing component is arranged inside the corridor body 1, and the fixing component is used for connecting and fixing functions, and the fixing component includes an anchor bolt 14, and the anchor bolt 14 is threadedly connected to the inside of the corridor body 1, and an isolation seat 13 is arranged at the bottom of the corridor body 1, and the corridor body 1 and the connecting beam 2 are connected by the anchor bolt 14.

[0033] Specifically, when installing the corridor, first place the corridor body 1 above the connecting beam 2, and use the anchor bolts 14 to fasten the corridor body 1 to the connecting beam 2. At the same time, the connecting column 6 and the cone head 12 at the bottom of the corridor body 1 are inserted into the ground to ensure that the bracket 4 is firmly placed on the ground and fixed. Then, the connecting column 6 is driven to move by the output end of the cylinder 5, and the connecting column 6 drives the rotating rod 2 10 and the other fixed block 8 to drive the rotating rod 1 9 to rotate simultaneously through the action of one of the fixed blocks 8. The action of these rotating rods causes the support plate 11 connected to one side thereof to expand outward, so that it is supported in the ground, effectively supporting and fixing the corridor, ensuring that the corridor can stand firmly on the ground after installation, and having additional support and fixing functions.

[0034] Reference Figure 1 and Figure 4 A fixing frame 15 is fixedly connected to one side of the corridor body 1, a motor 16 is fixedly connected to one side of the fixing frame 15, a screw rod 17 is fixedly connected to the output end of the motor 16, a connecting block 18 is threadedly connected to the outer wall of the screw rod 17, and a connecting rod 19 is rotatably connected to one side of the connecting block 18.

[0035] Specifically, when the top of the corridor needs to be closed, the output end of the motor 16 is used to drive the screw 17 to rotate inside the connecting block 18. The threaded relationship between the screw 17 and the connecting block 18 causes the connecting block 18 to move up and down under force, while driving the connecting rod 19 connected to one side to rotate, thereby achieving the effect of motion transmission.

[0036] Reference Figure 1 and Figure 4 One side of the connecting rod 19 is rotatably connected to a support rod 22, one side of the corridor body 1 is fixedly connected to a support column 20, the outer wall of the support column 20 is slidably connected to a connecting frame 21, one side of the support rod 22 is rotatably connected to one side of the connecting frame 21, one side of the support rod 22 is rotatably connected to a pulley 23, the pulley 23 is slidably connected to the inside of the connecting frame 21, a fixed column 25 is fixedly connected to the inside of the connecting frame 21, and a shielding cloth 24 is provided on the outer wall of the fixed column 25.

[0037] Specifically, the force of the connecting rod 19 pushes the supporting rod 22 connected on one side to rotate, and the supporting rod 22 drives the pulley 23 connected on one side to slide inside the connecting frame 21. These actions cause the connecting frame 21 to slide on the outer wall of the supporting column 20. At the same time, the movement of the connecting frame 21 drives the multiple fixed columns 25 connected inside to move. Under the coordinated movement of the multiple fixed columns 25, the shielding cloth 24 is stretched and laid above the corridor, thereby achieving effective closure and protection of the corridor.

[0038] Working principle: When installing the corridor, first place the corridor body 1 above the connecting beam 2, and connect and fix the corridor body 1 and the connecting beam 2 through the anchor bolts 14, and at the same time insert the connecting column 6 and the cone head 12 at the bottom of the corridor body 1 into the ground, so that the bracket 4 is placed on the ground and fixed. At this time, the connecting column 6 is driven to move by the output end of the cylinder 5, and the connecting column 6 drives the rotating rod 2 10 to rotate through one of the fixed blocks 8 on the outer wall. At the same time, the other fixed block 8 will also drive the rotating rod 1 9 to rotate. Through the rotation of the rotating rod 2 10 and the rotating rod 1 9, the support plate 11 connected to one side is pushed outward, so that the corridor is supported and fixed in the ground, thereby achieving the effect of providing additional support for the corridor. When the top of the corridor needs to be closed, The output end of the motor 16 can drive the screw rod 17 to rotate inside the connecting block 18. Through the threaded relationship between the screw rod 17 and the connecting block 18, the connecting block 18 will be forced to move up and down. The connecting block 18 simultaneously drives the connecting rod 19 connected on one side to rotate. The connecting rod 19 is forced to push the supporting rod 22 connected on one side to rotate. The supporting rod 22 is forced to drive the pulley 23 connected on one side to slide inside the connecting frame 21, thereby causing the connecting frame 21 to slide on the outer wall of the supporting column 20. At the same time, the connecting frame 21 will be forced to drive the internally connected fixed column 25 to move. Through the movement of multiple fixed columns 25, the shielding cloth 24 is driven to extend, so that it is laid above the corridor to close it, thereby achieving the effect of protecting the corridor.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
