It is understood that the aforementioned solution allows for precise adjustment of the segment assembly position during segment lifting and assembly.

[0018] In this embodiment, the main body 101 of the tube segment is provided with a plurality of operating cavities 102, and a platform portion 103 is provided in the operating cavity 102. The operating cavity 102 and the platform portion 103 facilitate the installation or removal of the first nut 106 and the second nut 108.

[0019] The hanger 104 is disposed on the top side of the segment body 101. The first arc-shaped screw 105 is detachably connected to both the hanger 104 and the segment body 101. The first nut 106 is threadedly connected to the first arc-shaped screw 105 and abuts against the platform portion 103 of the operating cavity 102 on both sides of the segment body 101. The second arc-shaped screw 107 is detachably connected to both the hanger 104 and the segment body 101 and is located at the center point between the first arc-shaped screw 105. The second nut 108 is threadedly connected to the second arc-shaped screw 107 and abuts against the platform portion 103 of the operating cavity 102 in the middle of the segment body 101. The connecting plate 109 is symmetrically disposed on the top of the hanger 104. The hook device is rotatably mounted on the connecting plate 109. The reinforcing device is disposed on the hanger 104. The reinforcing boss 110 is detachably connected to the hanger 104 and is connected to the connecting plate 109. Plate 109 abuts against; the hanger 104 is provided with corresponding mating through holes, and the segment body 101 is provided with mating holes. After the two mating holes are engaged, they are used for the installation of the first arc-shaped screw 105 and the second arc-shaped screw 107. The first nut 106 is used to cooperate with the first arc-shaped screw 105 to connect and fix the segment body 101 to the hanger 104. The second nut 108 is used to cooperate with the second arc-shaped screw 107 to connect and fix the segment body 101 to the hanger 104. The reinforcing boss 110 is provided with a clearance cavity for the head of the connecting bolt of the connecting plate 109 to be cleared. The reinforcing boss 110 is fixed to the hanger 104 by bolts. After installation, it can cooperate with the main reinforcing rib 113 to provide a two-sided limiting structure for the connecting plate 109, thereby improving the stability of the connecting plate 109 after installation. The hook device cooperates with the external hoisting wire rope. The reinforcing device is used to improve the stability of the hanger 104.

[0020] Cotter pin holes are respectively provided on the ends of the first arc-shaped screw 105 and the second arc-shaped screw 107 away from the hanger 104. Since cotter pin holes are provided on the threaded ends of the first arc-shaped screw 105 and the second arc-shaped screw 107, after the first nut 106 and the second nut 108 are installed, cotter pins can be installed in the cotter pin holes on the first arc-shaped screw 105 and the second arc-shaped screw 107 respectively, facilitating the prevention of loosening of the first nut 106 and the second nut 108 during hoisting.

[0021] Secondly, the auxiliary hook 111 is rotatably mounted on the connecting plate 109 via the connecting member 112; the connecting member 112 is symmetrically arranged on the connecting plate 109. The connecting member 112 adopts a T-shaped pin and a limiting nut. The optical shaft end of the T-shaped pin is used for rotation of the auxiliary hook 111 during installation and operation, and the limiting nut is used for tensioning and limiting.

[0022] Then, the main reinforcing rib 113 is disposed on the top of the hanger 104 and detachably connected to the connecting plate 109; the auxiliary reinforcing ribs 114 are disposed on both sides of the main reinforcing rib 113. The main reinforcing rib 113 and the auxiliary reinforcing ribs 114 cooperate to improve the stress stability of the hanger 104. The second arc-shaped screw 107 is disposed on the rear side of the main reinforcing rib 113. The connecting plate 109 is installed on the main reinforcing rib 113 by a T-shaped screw and a nut.

[0023] Furthermore, the straight rib 115 is integrally formed with the hanger 104 and the main reinforcing rib 113, and is symmetrically arranged. The straight rib 115 further cooperates with the main reinforcing rib 113 to improve the stress stability of the hanger 104.

[0024] Finally, the operating cavities 102 are also symmetrically distributed in the vertical direction of the segment body 101. This structure will facilitate hoisting from both sides of the segment body 101.

[0025] When using this utility model to solve the problem of difficulty in ensuring precise adjustment of the segment assembly position during the existing segment hoisting and assembly process, which easily leads to damage to the edges and corners of the segments, the segment body 101 is hoisted by first using the hook device and wire rope to move the lifting frame 104 to the top of the segment body 101. Then, the mating holes are aligned, and the first arc-shaped screw 105 and the second arc-shaped screw 107 are installed. The first nut 106 and the second nut 108 are then installed and tightened. After tightening, cotter pins are installed as needed. Finally, the segment body 101 can be hoisted for assembly. The hoisting tool of this application can make fine adjustments to the segment position during the three-ring horizontal assembly of the segments, ensuring the accuracy of the segment assembly, enabling rapid assembly, improving construction efficiency, reducing segment damage, and ensuring construction safety. Thus, it can solve the problem of difficulty in ensuring precise adjustment of the segment assembly position during the existing segment hoisting and assembly process, which easily leads to damage to the edges and corners of the segments.
