DETAILED DESCRIPTION

[0026] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] Example 1:

[0028] See also Figure 1-6 A tunnel segment installation device mounted on the tail of a mobile shield for full-section excavation comprises symmetrically arranged connecting beams 1, with arc-shaped mounting seats 3 rotatably mounted between the connecting beams 1 via a tilting shaft 2. A revolving outer ring 4 is fixed between the arc-shaped mounting seats 3, and a revolving inner ring 5 is rotatably mounted inside the revolving outer ring 4. The annular inner wall of the revolving inner ring 5 is provided with an inner gear ring 6, which cooperates with a rotary power device for driving the revolving inner ring 5 to rotate. The rotary power device is fixed to the outer wall of the revolving outer ring 4; a segment installation device for picking up and installing segments is mounted on the outer wall of the revolving inner ring 5. This device can be mounted on the tail of a mobile shield to install segments in the excavated section, thereby realizing the integrated construction of tunnel support, excavation, and segment installation, effectively improving the efficiency of full-section tunnel excavation and ensuring the safety of operations. When it is necessary to install the pipe segments, the pipe segments transported to the inside of the tunnel are picked up by the pipe segment installation device, and then the rotary power device is started to drive the inner ring 5 of the rotary body to rotate, and then the inner ring 5 of the rotary body drives the pipe segment installation device to rotate to the installation position on the inner wall of the tunnel, and then the pipe segments are installed. After the installation of one pipe segment is completed, the pipe segment installation device is reset to install the next pipe segment.

[0029] Furthermore, during installation, the two connecting beams 1 are arranged in parallel and fixedly connected to the inner sidewall of the rear end of the mobile shield 21. This fixed installation method allows the entire segment installation device to be securely mounted and fixed directly to the rear end of the existing mobile shield 21 without requiring redesign or modification of the mobile shield 21's main structure, thereby reducing modification difficulty and cost and improving R&D and design efficiency. Furthermore, the connecting beams 1 facilitate subsequent modular manufacturing and installation, improving operational and installation efficiency.

[0030] Furthermore, the rotary power device includes a connecting plate 15 fixed to the outer wall of the rotating outer ring 4, a crossbeam 14 is fixed between the outer sides of the connecting plate 15, and a rotary motor 20 is fixedly installed on the bottom middle part of the crossbeam 14 through a motor fixing seat 13. The output shaft 12 of the rotary motor 20 is installed with a first driving gear 11, and the first driving gear 11 is meshed with the inner ring gear 6 for transmission. The above-mentioned rotary power device can be used to drive the circumferential movement of the rotating outer ring 4, thereby realizing the installation of pipe segments in all positions of the tunnel section. During operation, when the circumferential position of the pipe segment needs to be adjusted, the rotary motor 20 is started, the output shaft 12 is driven by the rotary motor 20, the first driving gear 11 is driven by the output shaft 12, the inner ring gear 6 is driven by the first driving gear 11, and the pipe segment installation device is driven circumferentially by the inner ring gear 6, thereby changing the pipe segment installation position.

[0031] Furthermore, a triangular reinforcement plate 19 is fixed between the connecting plate 15 and the cross beam 14. The triangular reinforcement plate 19 enhances the strength and stability of the connection structure between the connecting plate 15 and the cross beam 14.

[0032] Furthermore, the segment installation device includes a curved plate 8 fixed to the outer wall of the inner ring 5 of the rotating body. A telescopic cylinder 9 is mounted on the outer wall of the curved plate 8 via symmetrically arranged hinge mounting seats 7. A curved segment installation plate 10 is mounted at the end of the telescopic cylinder 9. This segment installation device can be used to pick up and support segments, thereby facilitating subsequent segment installation. The curved segment installation plate 10 is provided with a segment connection mechanism for securing segment lifting lugs, thereby securing the segment to be installed to the curved segment installation plate 10. Once the curved segment installation plate 10 is locked to the segment, the telescopic cylinder 9 is activated to pick up the segment. The segment is then rotated to the circumferential direction of the tunnel where it is to be installed, using the rotary power device. The telescopic cylinder 9 is then activated to press the segment against the inner wall of the tunnel, further locking the segment. After installation is complete, the curved segment installation plate 10 is released, and the segment installation device is reset.

[0033] Example 2:

[0034] Since the outer ring 4 of the gyroscope is arranged concentrically with the tunnel during use, it may block the tunnel passage and affect the transportation of excavated soil inside the tunnel. Therefore, it is necessary to ensure that the outer ring 4 of the gyroscope can be flipped to a horizontal position when the segments are not being installed. This will reserve the lower passage of the tunnel and will not affect the transportation of excavated soil by the internal transport vehicles. Based on this, a flipping power device is designed to achieve the flipping of the outer ring 4 of the gyroscope.

[0035] Therefore, in this embodiment, a turning power device is installed between the turning shaft 2 and the connecting beam 1 on one side to drive the turning of the entire revolving outer ring 4. This turning power device can achieve the turning of the revolving outer ring 4 from a vertical position to a horizontal position, thereby ensuring that the entire segment installation equipment does not affect traffic inside the tunnel.

[0036] Furthermore, the flipping power device includes a flipping motor 17 fixed to the top of the connecting beam 1. The output shaft of the flipping motor 17 is mounted with a second driving gear 16. The second driving gear 16 is meshed with a driven gear 18 for transmission. The driven gear 18 is fixedly mounted on the flip shaft 2. During operation, the flipping motor 17 drives the second driving gear 16, which in turn drives the driven gear 18. The driven gear 18 drives the flip shaft 2, which in turn drives the rotating outer ring 4 to rotate.

[0037] Working process and principle of this utility model:

[0038] During the specific working process, the segment installation device is installed as a whole at the rear of the mobile shield 21, and then the segment to be installed is fixed on the curved segment installation plate 10. After the curved segment installation plate 10 is locked with the segment, the telescopic cylinder 9 is started to pick up the segment. When the circumferential position of the segment needs to be adjusted, the rotary motor 20 is started, and the output shaft 12 is driven by the rotary motor 20, and the first driving gear 11 is driven by the output shaft 12, and the inner gear 6 is driven by the first driving gear 11, and the inner gear 6 drives the segment installation device to move circumferentially. Then change the installation position of the segment, rotate the segment to the circumferential direction of the tunnel where it needs to be installed, start the telescopic cylinder 9, and use the telescopic cylinder 9 to push the segment against the inner wall of the tunnel to lock the segment. After the installation is completed, loosen the arc segment mounting plate 10, and then reset the segment mounting device. After the installation is completed, in order not to affect the passage, drive the second driving gear 16 through the flip motor 17, drive the driven gear 18 through the second driving gear 16, drive the flip shaft 2 through the driven gear 18, and drive the rotating outer ring 4 to rotate through the flip shaft 2.
