[0021] Figure 1-Figure 3 The main structural components of a shield segment transport and hoisting device are shown, including a base 1, on which a conveying track 2 and a bracket 3 are provided. The characteristic is that tracks 6 are provided on both sides of the bracket 3, and an annular track 4 is connected to the track 6. An annular mounting frame 5 is provided on the side of the annular track 4 away from the bracket 3, and hydraulic rods 8 are provided on both sides of the annular mounting frame 5. The output end of the hydraulic rod 8 is fixedly connected to a mounting frame 10, and the ground of the mounting frame 10 is fixedly connected to a grabbing plate 12 for hoisting the shield segment.

[0022] like Figure 1 As shown, the adjustment of the installation position is mainly completed by the combination of the electric slide rail 7 and the track 6. The electric slide rail 7 is fixedly connected to the inner side of the track 6, and the annular track 4 is connected to the track 6 through the electric slide rail 7. When the electric slide rail 7 is started, the slider on it will drive the annular track 4 to move linearly along the track 6.

[0023] like Figure 1 As shown, in actual operation, the adjustment of the installation angle is completed by the combination of the annular track 4 and the annular mounting frame 5, and the annular mounting frame 5 is rotatably connected to the annular track 4.

[0024] The annular mounting frame 5 is driven by a rotation control motor 13 on the annular mounting frame 5 to rotate on the annular track 4, thereby changing the angle between the hydraulic rod 8 on the annular mounting frame 5 and the horizontal ground, thereby completing the adjustment of the installation angle.

[0025] like Figure 3 As shown, the main component for completing the segment hoisting is the grab plate 12. The underground surface of the grab plate 12 is provided with a plurality of hooks to achieve the grabbing and fixing of the segment.

[0026] A fixing clamp 9 is provided on the annular mounting frame 5 , and the hydraulic rod 8 is fixedly mounted on the annular mounting frame 5 via the fixing clamp 9 .

[0027] A fixing ring 11 is provided on the mounting frame 10 , and a grab plate 12 is fixedly mounted on the bottom surface of the fixing ring 11 . The grab plate 12 is connected to the mounting frame 10 through the fixing ring 11 .

[0028] In order to ensure that the grabbing plate 12 can accurately lift the pipe segment, the grabbing plate 12 is placed directly above the conveying track 2.

[0029] The working principle of the shield segment transfer and hoisting device is as follows:

[0030] In actual work, the pipe segment is transported by the transport track. When the pipe segment is transported to the ground directly below the grab plate 12, the hydraulic rod 8 pushes the grab plate 12 to move downward to grab the pipe segment. Then the electric slide rail 7 can drive the circular track 4 to move linearly in the track 6, so as to adjust the installation position; at the same time, the rotation control motor 13 drives the circular mounting frame 5 to rotate in the circular track 4, so as to adjust the angle between the mounting frame 10 on the hydraulic rod 8 and the horizontal ground, and complete the adjustment of the installation angle.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
