Description

Technical Field

[0001] This application relates to the field of tunnel equipment technology, and in particular to a tunnel segment transfer device. Background Technology

[0002] Tunnel segments are prefabricated, arc-shaped sheet-like components used for lining and support during the excavation process of a full-face tunnel boring machine (TBM). They can serve as temporary support measures during TBM excavation or as permanent support measures for the tunnel. During TBM excavation, there are supporting segment installation equipment at the rear, allowing for the immediate installation of segments on the exposed rock face after excavation. The segment lining consists of multiple rings along the longitudinal direction of the tunnel, with each ring composed of multiple segments connected by circumferential bolts. Each segment is arranged in an arc shape. After the rings are installed, gravel and grout are filled between the segments and the rock face, making the rock face and segments a unified whole. At this point, the segments can support locally unstable rock masses, resist external rock pressure and groundwater pressure, and maintain the tunnel shape.

[0003] In the traditional process of transferring tunnel segments from the warehouse to the construction site, the tunnel segments are usually tied together with ropes or chains. Then, the tied tunnel segments are transferred to the transport vehicle using lifting and handling machinery in conjunction with the ropes or chains. Finally, the tunnel segments are transported to the construction site for use.

[0004] However, in the existing technology, tunnel segments are bound by ropes or chains, which requires multiple people to work together to complete the task. This is very inconvenient, time-consuming and labor-intensive, and affects the efficiency of tunnel segment transportation. Utility Model Content

Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the second locking assembly 22 is rotatably connected to the first locking assembly 21. The second locking assembly 22 includes a rotating box 221, a connecting rod 222 fixed to the rotating box 221, and a lock head 223 fixed to the connecting rod 222. The rotating box 221 is placed inside the receiving cavity 11C. An opening 221A is provided on one side of the rotating box 221. The threaded rod 212 passes through the opening 221A through the rotating box 221. A locking head 214 is disposed inside the rotating box 221 and can rotate freely inside the rotating box 221. The connecting rod 222 passes through the through hole 11B through the first support assembly 11 and the second support assembly 12 respectively. Here, the lock head 223 is arc-shaped. The locking mechanism 20 has the same connection relationship with the second support assembly 12. Here, the locking head 214 rotates freely inside the rotating box 221, realizing that according to the position of the tunnel segment 40, the locking head 223 is rotated to manually engage the locking head 223 with the corresponding position of the tunnel segment 40, and then the rotating device is operated to clamp the tunnel segment 40.

[0048] Continue to refer to Figure 2 and Figure 9 One end of the extended support rod mechanism 30 is provided with a connector 121, and the other end is provided with a connection hole 11A. The connector 121 on one extended support rod mechanism 30 cooperates with the connection hole 11A of another extended support rod mechanism 30 or the connection hole 11A near the inner end of the first support component 11, so as to extend the length of the original support rod mechanism 10 according to the width of the tunnel segment 40 when transporting tunnel segments 40 of different widths, effectively improving the adaptability of the transport device.

[0049] refer to Figure 10 and Figure 11 , Figure 10 This is a perspective view of a tunnel segment transfer device according to this application. Figure 11 yes Figure 10 An enlarged view of circle B shown. Figure 10 and Figure 11 As shown, the tunnel segment 40 is provided with a hook groove 41. Furthermore, the hook groove 41 on the tunnel segment 40 cooperates with the lock head 223 to realize the clamping connection between the transfer device and the tunnel segment 40, so as to prepare for the transfer of the tunnel segment 40 by the transfer device.

[0050] Here, there is a detachable support rod mechanism 10, a locking mechanism 20 connected to the support rod mechanism 10, and an extended support rod mechanism 30. The first support component 11 and the second support component 12 in the support rod mechanism 10 are detachably connected. The ends of the first support component 11 and the second support component 12 near the outer end are provided with through holes 11B. The second locking component 22 in the locking mechanism 20 is rotatably connected to the first locking component 21. The first locking component 21 and the second locking component 22 pass through the first support component 11 and the second support component 12 respectively through the through holes 11B. This makes the operation of the tunnel segment 40 convenient, saves time and manpower, and effectively improves the transportation efficiency of the tunnel segment 40 during the transportation process.

[0051] To facilitate understanding, the working principle of this application is further described as follows: The tunnel segment transfer device determines whether it is necessary to select an extended support rod mechanism 30 of the appropriate specification to extend the support rod mechanism 10 and to select a locking mechanism 20 of the appropriate specification, based on the width of the tunnel segment 40 and the required clamping thickness of the transfer device, so as to meet the transfer requirements of the tunnel segment 40.

[0052] During use, the locking head 223 in the locking mechanism 20 on the first support assembly 11 and the second support assembly 12 is partially or completely placed inside the hook groove 41. By rotating the locking ring 213, the locking ring 213 and the threaded rod 212 cooperate to clamp the pressure bar 111 and the locking head 223 at the corresponding position of the tunnel segment 40. Then, a lifting device is connected to the connecting hole 11A near the outer end of the first support assembly 11 and the second support assembly 12. Then, multiple transfer devices can be connected to one tunnel segment 40 in sequence. Finally, the lifting and handling machinery lifts the transfer device and the tunnel segment 40 clamped by the transfer device through the external lifting device for transfer, which improves the convenience of operation, saves time and manpower, and improves the transfer efficiency of the tunnel segment 40.
