[0002] The fault fracture zone of a tunnel refers to a long strip of rock fracture zone that is basically consistent with the fault plane direction, which is formed by the relative sliding of the two plates of the fault, causing the rock layers on both sides to be dislocated and broken. This fracture zone is mainly composed of tectonic rocks, including tectonic breccia, conglomerate, mylonite and fault mud. Since this fracture zone is relatively fragile, it is necessary to use external support devices to reinforce and protect it to ensure the stability of the tunnel.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0025] In this embodiment: a large-section tunnel fault fracture zone support device includes a device body 1, a control panel 2, and a motor 3, wherein the control panel 2 is arranged on the outer end surface of the device body 1, and the motor 3 is arranged on the side end of the device body 1;

[0026] A displacement support frame 4 is provided on the inner end surface of the equipment body 1;

[0027] The device body 1 further includes a driving gear 101 and a transverse pad 102 . The driving gear 101 is movably connected to the side wall of the device body 1 , and the transverse pad 102 is welded to the inner end of the device body 1 away from the motor 3 .

[0028] In this embodiment, a plate-shaped mounting base structure is further provided at the bottom of the device body 1. The device body 1 is specifically an irregular structure sandwiched on both sides, and the motor 3 is fixedly installed at the side end of the gap in the middle; the displacement support frame 4 also includes a bracket 401, a linkage shaft 402, and a driven gear 403. The bracket 401 is movably connected to the top of the displacement support frame 4, the linkage shaft 402 runs through the inside of the displacement support frame 4 and establishes a movably connected thereto, and the driven gear 403 is fixedly installed at the side end of the linkage shaft 402;

[0029] Specifically, Figure 1 and Figure 3 As shown, the linkage shaft 402 that runs through the equipment body 1 and the bottom end of the displacement support frame 4 serves as a support for the displacement support frame 4 to rotate, so that the displacement support frame 4 can provide good flexibility when performing support operations;

[0030] In this embodiment, four sets of shafts and six sets of rectangular block structures are also provided at the position where the bracket 401 is connected to the displacement support frame 4, which enables the bracket 401 to have a small rotation effect; the linkage shaft 402 and the driving gear 101 are both provided with bearing assemblies at the position where they contact the device body 1;

[0031] Specifically, Figure 2 and Figure 4 As shown, the multiple groups of shaft bodies and rectangular blocks connected to the displacement support frame 4 at the bottom of the bracket 401 form a parallelogram structure, so that the bracket 401 can be slightly offset left and right. During the support operation, this slight offset can make the bracket 401 fit better with the inner wall of the tunnel;

[0032] In this embodiment, the maximum angle that the displaceable support frame 4 can rotate through the linkage shaft 402 is 110°, and it can rotate completely parallel to the ground when it is rotated toward the side away from the motor 3; the middle part of the displaceable support frame 4 adopts a hollow structure, the driving gear 101 and the driven gear 403 are meshed with each other, and the driving gear 101 also establishes an active connection relationship with the motor 3.

[0033] The working principle and use process of the present invention are as follows: before the operation of the structure, the operator needs to install it at the position inside the tunnel that needs support and reinforcement, and then the operator controls the motor 3 to start through the control panel 2. The motor 3 drives the driven gear 403 through the driving gear 101, and the driven gear 403 drives the displacement support frame 4 passing through it through the connection with the linkage shaft 402. The displacement support frame 4 rotates with the support of the linkage shaft 402 until the bracket 401 on its top rotates to the position in the tunnel that needs reinforcement and support, and then continues to rotate slightly until the upper end face of the bracket 401 is close to the inner wall of the tunnel.

[0034] Finally, it should be noted that the above description 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 replace some of the technical features therein by equivalents.
