[0034] Please refer to the attached Figure 1-Figure 5 , shows the inclined shaft TBM retreat prevention structure 3 provided in an embodiment of the present application, including: a door panel 301, a fixing clamp 302, a U-shaped clamp 304, and a clamping assembly 307.

[0035] Among them, the surface of the door panel 301 is provided with a door-shaped opening corresponding to the "box-type" track 1, so that it can be stuck on the "box-type" track 1, the fixed clip 302 is fixedly connected to one side of the door panel 301, and one end of the U-shaped clip 304 is fixedly connected to the movable clip 303, and the movable clip 303 cooperates with the fixed clip 302 in a sliding and fastening manner. Relying on the sliding and fastening connection structure of the movable clip 303 and the fixed clip 302, the door panel 301 and the U-shaped clip 304 can be installed together. The U-shaped clip 304 has a clamping deformation part 306, and the clamping assembly 307 is installed on the U-shaped clip 304, and a clamping force is applied to the clamping deformation part 306, so that the clamping deformation part 306 is deformed inward and squeezed on the outside of the "box-type" track 1.

[0036] like Figure 1 , 2 As shown, the running wheels 2 of the trailer are located on the "box-type" track 1 and roll. When the trailer needs to brake, the inclined shaft TBM anti-retreat structure 3 is installed on the "box-type" track 1 and is located obliquely below the running wheels 2 of the trailer, thereby preventing the running wheels 2 from sliding obliquely downward along the "box-type" track 1, thereby achieving the purpose of "anti-retreat".

[0037] When installing the inclined shaft TBM retreat prevention structure 3, first clamp the door panel 301 at a position about 10 cm away from the trailer's running wheels, and then install the U-shaped clamp 304, which is also clamped on the "box-type" track 1, and tighten the clamping assembly 307 to make the clamping deformation part 306 deform inward, squeezing the "box-type" track 1, thereby achieving the fixation of the U-shaped clamp 30 and the "box-type" track 1, and the U-shaped clamp 30 is against one side of the door panel 301, so that the door panel 301 is also fixed.

[0038] In one embodiment, the movable clamp 303 and the fixed clamp 302 are interlocked, and both the movable clamp 303 and the fixed clamp 302 are horizontally U-shaped, like two hands interlocking, and the structural connection is stable and reliable.

[0039] In one embodiment, there is a gap portion 305 between the clamping deformation portion 306 and the fixed clamp 302. The fixed clamp 302 is thicker, and the gap portion 305 is set between the clamping deformation portion 306 and the fixed clamp 302, so that the clamping deformation portion 306 itself is easy to deform without affecting the fixed clamp 302.

[0040] In one embodiment, an anti-slip bevel 3a is provided on the top of the clamping deformation portion 306, and an anti-slip bevel corresponding to the anti-slip bevel 3a is provided on the clamping assembly 307. The anti-slip bevel 3a is inclined downward and the anti-slip bevel is inclined upward, so that after the clamping assembly 307 is clamped, it cannot slide upward relative to the clamping deformation portion 306, thereby making the structure safe and reliable.

[0041] In one embodiment, the clamping assembly 307 includes: a first bracket 3071 and a second clamp 3072 . The tops of the first bracket 3071 and the second clamp 3072 both have ears, and a pulling assembly 3073 is installed between the ears of the first bracket 3071 and the ears of the second clamp 3072 .

[0042] The first clamping frame 3071 and the second clamping member 3072 are brought closer to each other by means of the pulling assembly 3073, so as to achieve the purpose of clamping.

[0043] In one embodiment, the pulling assembly 3073 includes: a double-headed screw 30731, and a first nut 30732 and a second nut 30733 are respectively threadedly installed at both ends of the double-headed screw 30731. By rotating the first nut 30732 and the second nut 30733, the first bracket 3071 and the second bracket 3072 are moved closer to the middle to achieve the purpose of extrusion and clamping.
