[0017] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present application and its application or use.

[0018] As Figure 1 and Figure 2 shown, in this embodiment, a fixed flipping device includes a fixed base 1, a clamping assembly, and a driving body; a rotatable fixed seat 2 is provided on the fixed base 1; during use, the component in the excavator: the cantilever section 11 is fixed to the rotatable fixed seat 2 with bolts. The clamping assembly includes a clamping pin shaft 4 and a V-shaped fixture 3. The clamping pin shaft 4 is installed in the through hole of the fixed base 1, and this through hole is located at the center of the arc. A V-shaped fixture 3 is sleeved on one side of the clamping pin shaft 4 close to the rotatable fixed seat 2. The V-shaped fixture 3 is movably and limit-fitted on the clamping pin shaft 4 and is locked by a fastener; the driving body is installed on the side plate of the fixed base 1, and one end of the clamping pin shaft 4 facing the driving body is axially movably connected to the output end of the driving body; wherein the rotatable fixed seat 2 fixes the cantilever section 11, the V-shaped fixture 3 movably abuts against the workpiece, and the driving body is started to drive the workpiece to flip; for the cantilever section 11, it can rotate 180°.

[0019] In some embodiments, the specific structure of the fixed flipping device is as follows; As shown in the attached Figure 1As shown, the fixed base 1 is composed of side plates and reinforcing ribs. The reinforcing ribs are used to enhance the overall strength of the base, and the structure is symmetrically distributed. At this time, two sets of clamping assemblies are correspondingly arranged and are installed corresponding to the two side plates one by one. Arc grooves 101 are provided on the opposite surfaces of the two side plates. At this time, the through holes on the side plates are located at the center of the arc of the arc, so that the clamping pin 4 can drive the cantilever section 11 to smoothly perform a flipping motion. The rotating fixed seat 2 is installed in the arc groove 101 through a rotating shaft, and the movement radius of the cantilever section 11 during flipping is the same as the arc diameter of the arc groove 101; considering the protection of the cantilever section 11, elastic rubber is fixed on the working surfaces of the two V-shaped clamps 3 during use.

[0020] Combined with the attached Figure 2 and Figure 3 , in a further embodiment, the position of the clamping pin 4 can be adjusted and can move axially. At this time, the coupling between the clamping pin 4 and the output end of the driving body needs to be redesigned. In addition, the clamping pin 4 is also different from a conventional shaft part during production, and four sections are respectively provided on the clamping pin 4; The first section is for connecting the V-shaped clamp 3. An installation hole is provided in the middle of the V-shaped clamp 3, and a limit groove is provided on the inner wall of the installation hole. A limit block 41 is integrally provided on the first section of the clamping pin 4. The V-shaped clamp 3 moves along the length direction of the clamping pin 4, so that the limit block 41 cooperates with the limit groove. At this time, the radial rotation of the V-shaped clamp 3 and the clamping pin 4 is restricted; The second section is for the cooperation of the external thread and the fastener. Here, a second thread 42 is provided on the first section of the clamping pin 4, and the fastener is selected as the fixing nut 5. The fixing nut 5 is threadedly connected with the second thread 42. When the V-shaped clamp 3 cooperates with the limit block 41, the fixing nut 5 is rotated to fix the V-shaped clamp 3 and transmit torque; The third section is for the cooperation of the external thread and the adjusting nut 6. Here, a first thread 43 is provided on the third section of the clamping pin 4. Through the screw-nut pair structure, the V-shaped clamp 3 presses the shell of the cantilever section 11 on the basis of being pressed by the clamping pin 4, realizing double fixation; during use, ensure that the adjusting nut 6 does not move, rotate the clamping pin 4 to realize the axial movement of the clamping pin 4, and then realize the pressing of the V-shaped clamp 3 on the cantilever section 11; The fourth section is a flat key section. A flat key 44 is integrally provided on the fourth section of the clamping pin shaft 4. A strip-shaped groove is formed on the coupling. The flat key 44 is movably placed in the strip-shaped groove, and the clamping pin shaft 4 and the coupling can move axially. Considering that the adjusted clamping pin shaft 4 needs to be positioned, an axial positioning frame 8 is fixed on the opposite surfaces of the two side plates of the fixed base 1. When the clamping pin shaft 4 rotates and adjusts, the adjusting nut 6 thereon will be axially restricted by the axial positioning frame 8. At this time, it can rotate with the output end of the driving body, realizing the switching between the axial feeding and the circumferential rotation of the clamping pin shaft 4. In addition, in order to facilitate the fixing of the adjusting nut 6, a fixing fork 7 is movably penetrated through the axial positioning frame 8. The fork head at the lower end of the fixing fork 7 contacts the adjusting nut 6 to prevent the adjusting nut 6 from rotating radially. The fixing fork 7 is used in cooperation with the adjusting nut 6. When the fixing fork 7 drops, it can prevent the nut from rotating. Then, the clamping pin shaft 4 can realize axial feeding. When the fixing fork 7 is lifted and disengaged from the adjusting nut 6, the adjusting nut 6 and the clamping pin shaft 4 rotate circumferentially together. The function of the axial fixing frame is to axially limit the adjusting nut 6. In some other embodiments, a limiting groove is provided on the surface of the axial fixing frame facing the side plate for placing the adjusting nut 6. The depth of the limiting groove needs to be less than the thickness of the adjusting nut 6. At the same time, a spring is installed between the fixing fork 7 and the axial fixing frame. It should be noted here that after the spring is installed, the fixing fork 7 is in a lifted state without external force. This is convenient for the use of the equipment.

[0021] In this embodiment, the output end of the driving body, which is the output end of a three-phase asynchronous motor 10, is connected to the clamping pin shaft 4 through a coupling. The clamping pin shaft 4 passes through the axial positioning frame 8 and is connected to the output end of the three-phase asynchronous motor 10. Figure 2 On the left side in the attachment, the driving body is not installed. At this time, the clamping pin shaft 4 passes through the corresponding axial positioning frame 8.

[0022] A cycloid pinwheel 9 is installed at the output end of the three-phase asynchronous motor 10 for reducing the speed of the three-phase asynchronous motor 10. At the same time, it provides self-locking ability, which belongs to the prior art and will not be elaborated here.

[0023] In the attachment Figure 3 In this embodiment, the clamping components are arranged bidirectionally and are installed on the two side plates of the fixed base 1. The two clamping components are symmetrically distributed.

[0024] Specific use; There are many ways of use, which are explained below with examples; first, fix the cantilever section 11 on the rotating fixed seat 2 by bolts, then make a preliminary adjustment to the length of the clamping pin 4 between the two side plates according to the diameter of the cantilever section 11, press the fixing fork 7 down to fix the adjusting nut 6, and rotate the clamping pin 4 to adjust the overall position of the clamping pin 4; thereafter, lift the fixing fork 7, move the V-shaped clamp 3 to the first section of the clamping pin 4 for limiting, and finally apply pressure to the V-shaped clamp 3 by rotating the fixing nut 5 to achieve a stable tightening of the cantilever section 11 by the V-shaped clamp 3; at this time, start the driving body and the cantilever section 11 performs a flipping movement along the arc groove 101; the installation of the cantilever section 11 is greatly facilitated, and the flipping scheme during the assembly process of the cantilever section 11 of the tunnel boring machine replaces the flipping by vehicle dragging, which can greatly improve the assembly efficiency and safety.
