[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figure 1 As shown, a TBM inverted arch block turning device includes a crane body 1, and the left and right sides of the crane body 1 are rotatably connected to a first arm 2 and a second arm 3 for clamping the inverted arch block. The lower ends of the first arm 2 and the second arm 3 are provided with a turning mechanism for turning the inverted arch block.

[0025] like Figure 2 As shown, the flipping mechanism includes a rotating motor 7, a first connecting mechanism 4, a second connecting mechanism 5, a small gear 8 and a large gear 9. The first connecting mechanism 4 is rotatably connected to the lower end of the first holding arm 2, and the second connecting mechanism 5 is rotatably connected to the lower end of the second holding arm 3. The large gear 9 is fixedly mounted on the first connecting mechanism 4 and the second connecting mechanism 5. The rotating motor 7 is fixedly mounted on the first holding arm 2, and the small gear 8 is fixedly mounted on the output end of the rotating motor 7. The small gear 8 and the large gear 9 are connected by a chain.

[0026] like Figure 1-3As shown, the top of the first arm 2 is connected to the hanging body 1 through the first hydraulic cylinder 11, and the middle part of the first arm 2 is connected to the left side of the hanging body 1 through double lifting ears and pins; the top of the second arm 3 is connected to the hanging body 1 through the second liquid cylinder, and the middle part of the second arm 3 is connected to the left side of the hanging body 1 through double lifting ears and pins. A hydraulic pump 6 is fixedly installed on the hanging body 1, and the first hydraulic cylinder and the second liquid cylinder are both connected to the hydraulic pump 6. The extension and contraction of the hydraulic cylinder can be achieved by controlling the hydraulic pump 6. When the hydraulic cylinder contracts, the arm rotates upward by a certain angle with the pin as the axis, and the arm is opened. When the hydraulic cylinder extends, the arm rotates downward by a certain angle with the pin as the axis, and the arm is closed, thereby realizing the tightening and loosening of the inverted arch block.

[0027] like Figure 1 and Figure 3 As shown, the first arm 2 is provided with a fixing hole, and the first connecting mechanism 4 is connected and fixed to the first arm 2 by bolts, nuts, and the fixing hole; the second arm 3 is provided with a fixing hole, and the second connecting mechanism 5 is connected and fixed to the second arm 3 by bolts and nuts. The first connecting mechanism 4 and the second connecting mechanism 5 are both discs.

[0028] like Figure 4 As shown, the first connecting mechanism 4 and the second connecting mechanism 5 are both provided with two cylinders corresponding to the two cylindrical holes on the two side surfaces of the inverted arch block, ensuring that the first connecting mechanism 4 can drive the inverted arch block to rotate when it rotates, and can exert force.

[0029] Working principle: When in use, the mold 10 is opened, the crane body 1 moves downward, and the hydraulic cylinder is extended and retracted by controlling the hydraulic pump 6. When the hydraulic cylinder contracts, the arm rotates upward by a certain angle with the pin as the axis, and the arm is opened, and the cylinder is aligned with the cylindrical holes on both sides of the arch block. The arm rotates downward by a certain angle with the pin as the axis, and the arm is closed. The arm holds the arch block tightly and the crane body 1 is raised; the arch block is lifted; the rotating motor 7 is started, and the rotating motor 7 drives the small gear 8 to rotate, and through the chain transmission, drives the large gear 9 to rotate, and drives the first connecting mechanism 4 to rotate. The second connecting mechanism 5 is rotated by the force of the first connecting mechanism 4, thereby realizing a 180-degree flip of the arch block.

[0030] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will also have various changes and improvements, and these changes and improvements will fall within the scope of the utility model to be protected.
