Through the cooperation of the transmission bar 205 and the transmission groove 208, the synchronous rotation of the connecting shaft 207 and the sprocket 209 is realized. In turn, the chain 2010 can drive one end of the hoisting belt 305 to rise while the other end falls. This applies a force to the shield tunnel segment, enabling it to smoothly rotate from a vertical state to a horizontal state.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, four sets of symmetrically distributed lifting rings 101 and wire ropes are used to steadily and securely suspend the lifting beam frame 1 at the designated lifting point position of the gantry crane, ensuring a safe and reliable lifting process and laying a solid foundation for the subsequent lifting of the tunnel segments. Based on the actual dimensions of the tunnel segments to be lifted, the electric cylinder 105 is activated to control its telescopic end, causing the adjusting seat 103 to slide horizontally along the guide crossbar 102, thereby adjusting the horizontal position of the connecting seat 206, thus facilitating the lifting of the two tunnel segments. Adjust the spacing of the lifting slings 305 to ensure they match the segment dimensions; adjust the total length between the auxiliary cylinder 403 and the pull rod 404 by rotating the knobs on the auxiliary cylinder 403 and pull rod 404 using the threaded connection between the pull rod 404 and the auxiliary cylinder 403; then use locking rings A401 and B406 to install the auxiliary cylinder 403 and pull rod 404 between the two sets of chains 2010, ensuring the chain spacing 2010 remains at the specified value; place the lifting slings 305... The hoisting belt 305 is placed in a suitable position on the tunnel segment to ensure even force distribution. The tunnel segment is then lifted. When the tunnel segment needs to be rotated after being hoisted to a suitable position, the motor is activated to rotate the worm gear 204. The worm gear 204 drives the drive shaft 202 via the worm wheel 203. The drive shaft 202 drives the connecting shaft 207 via the transmission bar 205 and transmission groove 208. The connecting shaft 207 drives the chain 2010 via the sprocket 209. The chain 2010 then moves the hoisting belt 305. 5 One end descends while the other rises, enabling the tunnel segment to flip from vertical to horizontal. During the flipping process, the auxiliary structure 4 maintains the stability of the chain 2010 spacing, ensuring a smooth and safe flipping process. Thanks to the ingenious cooperation between the U-shaped frame 301 and the connecting screw 302, as well as the precise locking and unlocking mechanism of the locking nut 303, construction personnel can efficiently and conveniently complete the disassembly of the lifting belt 305, greatly improving the efficiency of lifting equipment maintenance and replacement of the lifting belt 305.
